Description

  The present invention applies a static electric field to flying organisms such as spores of plant pathogenic fungi and / or small pests, and makes it difficult to move flying organisms by applying an electrostatic field, The present invention relates to a flying organism removal apparatus and a plant protection apparatus that remove flying creatures to prevent the occurrence of plant disease and insect damage.

  In the cultivation of agricultural and horticultural plants, many fungicides and insecticides are used for the purpose of preventing the occurrence of disease and insect damage. In institutional cultivation of agricultural and horticultural plants, once a spore of a pathogenic fungus or a pest invades into the facility, there is a very high possibility that the disease or pest will spread throughout the facility. For this reason, this risk is avoided by spraying the medicine before the occurrence of pest damage. However, acquisition of drug resistance of pathogenic bacteria and acquisition of drug resistance of pests have recently become problems, particularly in institutional cultivation, and it is currently difficult to completely suppress the occurrence of plant pest damage only by spraying drugs.

  Many diseases caused by plant pathogens (mainly mold) are caused by airborne infection. The main source of mold is spores, many of which are scattered by the wind.

  An air purifier is used to remove bacteria, spores and pollen in the air. As this air cleaner, a filter and / or an apparatus that removes bacteria, spores, pollen, and the like by an electrostatic precipitator are known.

  The filter is not effective unless it has finer holes than the one to be removed, and clogging is difficult, and long-term operation is difficult.

  An electrostatic induction dust collector using two metal electrodes and a plastic three-dimensional mesh screen installed in parallel therewith has been reported as one that increases the filter collection effect (for example, patent document). 1).

  Furthermore, there are known electric dust collectors of a wire discharge type that applies a high voltage to a metal wire and a needle discharge type that applies a high voltage to a needle tip (see, for example, Patent Document 2, Patent Document 3, Patent Document 4, etc.) ). In both of these, spores and pollen are charged by corona discharge and adsorbed by a collecting electrode to remove bacteria, spores and pollen.

  Many plant pests (mainly insects) fly and harm plants, or fly and lay eggs on plants, and hatched larvae harm plants.

  There is a lightning insecticidal device that kills pests that fly by high voltage. It is known that a general electric shock insecticidal device on the market causes an insect flying between electrodes to be electrocuted by arc discharge (for example, see Patent Documents 5 and 6).

  In addition, a method has been reported in which a kidnapping lamp is lit in the countryside at night and a high voltage of plus and minus is applied to the electric wire stretched in a net at the same time to discharge and burn the pests (for example, Patent Document 7, 8).

  The commercially available electric shock insecticide uses AC100V as the input power supply, and positive and negative voltages are alternately applied. Therefore, when a small pest is allowed to enter at a momentary low voltage, the passage is allowed. There is.

Insects that can be attacked by electric shock killers vary in size from large to small. If the distance between the electrodes is narrowed, discharge is likely to occur, but a large insect remnant or the like may be caught between the electrodes, which may cause the device to malfunction. Further, if the distance between the electrodes is increased, the discharge is less likely to occur, and it is necessary to increase the voltage in order to kill small insects.

  The present invention has been made in view of the above-described points, and the object of the present invention is to provide an electrostatic field to a flyable organism such as a spore of a plant pathogenic fungus that causes plant disease or insect damage, or a fungus body or a small pest. Even if it is captured and removed by applying the force of, or even if the removal is avoided, it can be killed by discharging to a creature that can fly, preventing the occurrence of plant diseases and insect damage The object is to provide an animal and animal removal device and a plant protection device.

  In order to achieve the above object, in the present invention, an electrostatic field is applied to a flying organism.

Specifically, the flying organism removal apparatus according to the present invention is:
At least one first conductor;
At least one second conductor disposed at a distance from the first conductor by a distance;
A power source for applying a predetermined DC voltage to the first conductor and the second conductor,
The flying creature is removed by an electric field generated by the first conductor and the second conductor.

  The flying organism removing apparatus according to the present invention includes a first conductor, a second conductor, and a power source.

  The first conductor and the second conductor may be at least one each. Moreover, when there are a plurality of first conductors and second conductors, the first conductors and the second conductors can be alternately arranged. The second conductor is arranged at a position separated from the position of the first conductor by one distance with respect to the position of the first conductor.

  The power source is electrically connected to the first conductor and the second conductor, and a DC voltage can be applied to the first conductor and the second conductor. It is only necessary to apply a predetermined DC voltage to the first conductor and the second conductor, and either one of the first conductor and the second conductor may be grounded. By applying a DC voltage between the first conductor and the second conductor, a constant electric field whose magnitude and direction do not change with time can be generated. By doing in this way, since an electric field can always be generated, the creatures that can fly can be accurately removed.

  As described above, when a DC voltage is applied to the first conductor and the second conductor, a constant electric field whose magnitude and direction do not change with time is generated. The “one distance” between the first conductor and the second conductor is such that when only the first conductor and the second conductor exist, no discharge occurs, but the first conductor and the second conductor When a flying creature exists between the two conductors, it is preferable to cause a discharge to occur through the flying creature. By doing in this way, discharge can be generated only when there is a flying creature between the first conductor and the second conductor, and the flying creature can be removed by the discharge.

  Moreover, it is preferable to arrange | position a 1st conductor and a 2nd conductor so that the strength of the electric field produced by a 1st conductor and a 2nd conductor changes with positions. For example, the shape and arrangement of the first conductor and the second conductor may be determined so that a parallel plate capacitor having a large area is not formed by the first conductor and the second conductor. In this way, by generating an electric field whose electric field intensity varies depending on the position (uneven electric field, non-uniform field), when the flying creature is charged, the Coulomb force is applied to the flying creature. If the flying creature is electrically neutral, the flying creature can be subjected to electrostatic induction to exert a gradient force. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing in this way, the opportunity which produces the discharge mentioned above can be increased, and the creature which can fly can be removed exactly.

The flying organism removing apparatus according to the present invention is
The first conductor is a plurality of linear or plate-like first conductors;
The plurality of first conductors are arranged to be substantially parallel to each other,
The plurality of first conductors are arranged along a predetermined first surface,
The second conductor is a plurality of linear or plate-like second conductors,
The plurality of second conductors are arranged to be substantially parallel to each other,
The plurality of second conductors are arranged along a predetermined second surface,
The first surface and the second surface are preferably separated from each other by the one distance.

  The first conductor described above is a first conductor having a linear or plate shape. The first conductor is composed of a plurality of things. The plurality of first conductors are arranged so as to be substantially parallel to each other. The plurality of first conductors need not be linear or rectangular, but may be arranged in a certain shape. The plurality of first conductors only need to be arranged at positions parallel to each other.

  The interval between the plurality of first conductors is sufficient for the plant to which air is supplied via the flying organism removing device, depending on the type of plant and the type of flying organism to be removed. What is necessary is just to set to the grade which can be distribute | circulated. Further, the interval between the plurality of first conductors is such that the plurality of first conductors are not shaded and light is applied to a plant to which air is supplied via the flying organism removing apparatus. Furthermore, it is preferable to determine appropriately according to the type of plant and the type of flying organism to be removed.

  Further, the plurality of first conductors are arranged along the first surface. The first surface is a virtual surface and is a virtual surface that characterizes the overall shape of the plurality of first conductors. Specifically, first, the shape of each of the plurality of first conductors is specified by the shape of one line. This can define a single line by defining the center of the conductor in a plane perpendicular to the longitudinal direction of the conductor and connecting the center along the longitudinal direction of the conductor. In this way, one line characterizing each of the plurality of first conductors can be determined. In addition, the shape of the line for characterizing each shape of the plurality of first conductors does not have to be a strict shape indicating the first conductor, but the entire shape of each of the plurality of first conductors. Any average shape that can be outlined is sufficient.

  The first surface can then be defined by identifying one surface such that a line characterizing the shape of each of the plurality of first conductors is approximately included. It is not necessary to specify a strict surface in which all of these lines are always included in the specification of the first surface, and it is only necessary that one approximately included surface is the first surface.

  For example, when each of the plurality of first conductors is constituted by a linear conductor and these conductors are juxtaposed so as to be parallel to each other, each of the plurality of first conductors is Can be identified by a straight line. Further, since the plurality of first conductors are juxtaposed in parallel to each other, the plane including these straight lines is one plane, and the first plane is the one plane.

  The shape of the first surface described above may be any shape as long as it can be defined in a certain shape such as a flat surface or a spherical surface, and may be appropriately determined according to the shape of the place where the flying organism removing device is installed. . The plurality of first conductors only need to be arranged along the first surface.

  The second conductor described above is a second conductor having a linear or plate shape. The second conductor is composed of a plurality of things. The plurality of second conductors are arranged so as to be substantially parallel to each other. The plurality of second conductors need not be linear or rectangular, but may be arranged in a certain shape. The plurality of second conductors only need to be arranged at positions parallel to each other. Further, the plurality of second conductors are arranged along the second surface. This second surface is also a virtual surface similar to the first surface described above, and is a virtual surface that characterizes the overall shape of the plurality of second conductors. What is necessary is just to identify a 2nd surface by the method similar to the 1st surface mentioned above.

  The shape of the second surface may be any shape as long as it can be defined in a fixed shape such as a flat surface or a spherical surface, and may be appropriately determined according to the shape of the place where the flying creature removing device is installed. The plurality of second conductors only need to be arranged along the second surface.

  With the configuration described above, the first conductor has a linear or plate shape, and the second conductor also has a linear or plate shape. By doing in this way, when both the 1st conductor and the 2nd conductor are linear, when the 1st conductor is linear and the 2nd conductor is plate shape, the 1st conductor Is plate-shaped and the second conductor is linear, there are four cases where both the first conductor and the second conductor are plate-shaped.

  In particular, when both the first conductor and the second conductor are linear, when the first conductor is linear and the second conductor is plate-like, and when the first conductor is plate-like In the three cases of the case where the second conductor is linear and the three cases, an electric field whose intensity varies depending on the position of the first conductor and the second conductor (a non-uniform electric field, non-uniform electric field). Field). When flying creatures are charged by such an unequal electric field or inhomogeneous field, the Coulomb force can be exerted on the flying creatures, and the flying creatures are electrically neutralized. In the case of sex, a gradient force can be exerted by causing electrostatic induction in a flying creature. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing in this way, the opportunity which produces the discharge mentioned above can be increased, and the creature which can fly can be removed exactly.

  When both the first conductor and the second conductor are plate-shaped, the first conductor and the second conductor are arranged so as not to be parallel to each other, or the first conductor Even when the second conductor and the second conductor are arranged in parallel, the first conductor and the second conductor generate an unequal electric field or a non-uniform field by arranging the facing surfaces to be different from each other. be able to. By doing in this way, the opportunity which produces discharge with respect to the creature which can fly can be increased, and the creature which can fly can be removed exactly.

  What is necessary is just to determine whether a 1st conductor or a 2nd conductor is linear form or plate shape with the cross-sectional shape of a 1st conductor or a 2nd conductor. In particular, when the first conductor or the second conductor has a long shape, is it linear in the cross section perpendicular to the longitudinal direction of the first conductor or the second conductor? Whether it is plate-like can be determined. In addition, when the first conductor and the second conductor have a plate shape, it is preferable that the first conductor and the second conductor be arranged so as to be substantially parallel to the direction of air flow so as not to hinder the air flow.

  The first surface and the second surface are disposed at positions separated by a distance. In particular, when both the first surface and the second surface are planar, it is preferable that the first surface and the second surface are arranged so as to be substantially parallel.

  Note that only the relationship between the first surface and the second surface is parallel, and there is no need for the plurality of first conductors and the plurality of second conductors to be parallel. For example, even if the longitudinal direction of the plurality of first conductors is the horizontal direction and the longitudinal direction of the plurality of second conductors is the vertical direction, the first surface and the second surface are substantially the same. What is necessary is just to be parallel. In addition, the longitudinal direction of the plurality of first conductors and the longitudinal direction of the plurality of second conductors may be any direction as long as the first surface and the second surface are substantially parallel. May be suitable.

  By doing in this way, the field of the electric field generated from the first conductor and the second conductor can be expanded, and the force by the electric field can be given to the flying creature accurately, or the flying creature It is possible to remove the living creatures that can fly by accurately causing discharge.

The plurality of second conductors are arranged to be substantially parallel to each other,
The plurality of second conductors are arranged along a predetermined second surface,
The first surface and the second surface are preferably separated from each other by the one distance.

  The first conductor described above is a first conductor formed in a mesh shape from a conductive material. The mesh is formed by knitting or bending a conductive wire, or the whole or part of the first conductor is formed by forming holes in a plate-like material, for example, by a conductive material. As long as it is formed so that it can be visually recognized finally as a mesh shape. The size of one mesh may be determined according to the type of creature that can fly. Also, it is not necessary for all mesh sizes to be the same. The shape of the mesh is preferably a substantially square or a substantially diamond shape, but may be other polygonal shapes.

  The first conductor is disposed along the first surface. The first surface is a virtual surface and is a virtual surface that characterizes the overall shape of the first conductor. The first surface does not have to be a strict shape showing the first conductor, but may be an average shape that can show an outline of the entire first conductor. The shape of the first surface may be any shape as long as it can be defined in a certain shape such as a flat surface or a spherical surface, and may be determined as appropriate according to the shape of the place where the flying creature removing device is installed. The 1st conductor should just be arrange | positioned so that the 1st surface may be followed.

  The second conductor described above is a second conductor having a linear or plate shape. The second conductor is composed of a plurality of things. The plurality of second conductors are arranged so as to be substantially parallel to each other. The plurality of second conductors need not be linear or rectangular, but may be arranged in a certain shape. The plurality of second conductors only need to be arranged at positions parallel to each other. Further, the plurality of second conductors are arranged along the second surface. This second surface is also a virtual surface similar to the first surface described above, and is a virtual surface that characterizes the overall shape of the plurality of second conductors. What is necessary is just to identify a 2nd surface by the method similar to the 1st surface mentioned above.

  The shape of the second surface may be any shape as long as it can be defined in a fixed shape such as a flat surface or a spherical surface, and may be appropriately determined according to the shape of the place where the flying creature removing device is installed. The plurality of second conductors only need to be arranged along the second surface.

  The first surface and the second surface are disposed at positions separated by a distance. In particular, when both the first surface and the second surface are planar, it is preferable that the first surface and the second surface are arranged so as to be substantially parallel.

  In this way, by using the first conductor as a mesh-like first conductor, an electric field (inhomogeneous electric field, non-uniform field) whose strength varies depending on the position can be more easily generated. Such non-uniform electric field and non-uniform field can exert coulomb force and gradient force on flying creatures, increasing the chances of causing discharge and accurately removing flying creatures. be able to.

  Further, by using the first conductor as a mesh-like first conductor, the air flow can be disturbed or vortex can be generated. By disturbing the flow of air, it is possible to increase the opportunity for living organisms that can fly in the region where the electric field generated by the first conductor and the second conductor described above is effectively present. The flying creature can be removed.

  In the above flying organism removing apparatus, the first conductor is a first conductor formed in a mesh shape, and the second conductor is a plurality of second conductors that are linear or plate-like. However, the first conductor may be a plurality of linear or plate-like first conductors, and the second conductor may be a second conductor formed in a mesh shape.

The flying organism removing apparatus according to the present invention is
Including at least two housing openings facing each other so as to allow air to flow, and supporting the first conductor and the second conductor;
The first surface and the second surface are preferably substantially parallel to at least one of the at least two housing openings.

  The flying organism removing apparatus according to the present invention includes a housing. This casing is formed with at least two casing openings. The at least two housing openings are formed so that air can flow, and are formed to face each other. In particular, it is preferable that two housing openings are formed so as to be substantially parallel to each other. Further, the first conductor and the second conductor described above are supported by the housing. By doing so, the first conductor and the second conductor are disposed between at least two housing openings.

  Furthermore, the first surface and the second surface described above are substantially parallel to at least one of the two housing openings. Note that the phrase “substantially parallel to the casing opening” means that the surface that can be defined by the edge of the casing opening is substantially parallel to the casing opening.

By doing in this way, discharge can be produced with respect to the flying organism which moves on the flow of the air which distribute | circulates over at least 2 housing | casing opening, and a flying organism can be removed exactly.
It is preferable to include a dielectric disposed at a position where dielectric polarization is generated by the electric field generated by the first conductor and the second conductor.

  The dielectric is disposed at a position where dielectric polarization occurs inside the dielectric due to an electric field generated by the first conductor and the second conductor. By doing so, an electric field can be generated by the dielectric polarization of the dielectric, and this electric field can also exert a force on the flying creature.

  In particular, the dielectric is preferably arranged and shaped so that the strength of the electric field generated by the dielectric polarization of the dielectric varies depending on the position. In this way, by generating an electric field whose electric field intensity varies depending on the position (uneven electric field, non-uniform field), when the flying creature is charged, the Coulomb force is applied to the flying creature. If the flying creature is electrically neutral, the flying creature can be subjected to electrostatic induction to exert a gradient force. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing so, it is possible to accurately capture flying creatures by the electric field generated by the dielectric polarization of the dielectric.

  Moreover, it is preferable to arrange | position in order of a dielectric material, a 1st conductor, and a 2nd conductor toward the plant to which air is supplied via a flying organism removal apparatus. By arranging in this way, first, it is possible to make the force due to the electric field generated by the dielectric polarization of the dielectric material difficult to move to the flying creature and to capture the flying creature. . Furthermore, even if the flying organism cannot be captured by the electric field generated by the dielectric polarization of the dielectric, the flying organism can be moved by the electric field generated from the first conductor or the second conductor. As a result of the discharge, the flying creature can be killed, so that the flying creature can be surely removed.

  Further, at least one dielectric is sufficient. When a plurality of dielectrics are provided, the arrangement of the first and second conductors and the dielectrics described above should be protected by the type of flying creatures to be removed and the flying creature removing device. They can be combined or changed as appropriate according to the type of plant.

The flying organism removing apparatus according to the present invention is
The dielectric is a plurality of plate-like dielectric plates; and
The plurality of dielectric plates are arranged so as to be substantially parallel to each other,
The plurality of dielectric plates are arranged along a predetermined third surface different from the first surface and the second surface,
The third surface is separated from the first surface and the second surface by a predetermined distance,
Each of the plurality of dielectric plates is preferably arranged so that air can pass between each of the plurality of dielectric plates.

  The dielectric is a dielectric plate having a plate shape. The plate-like shape includes both a flat shape and a curved shape. For example, a cylindrical shape is included in the plate shape regardless of the thickness. Thus, by using a plate-like shape, the dielectric plate can be lightened, and handling of the flying organism removing apparatus can be facilitated. Further, the shape of the dielectric plate may be a plate shape as a whole, and irregularities or the like may be formed on the surface of the dielectric plate. For example, grooves or dents may be formed on the surface of the dielectric plate.

  This dielectric plate has a dielectric property and consists of a plurality of members. The plurality of dielectric plates are arranged so as to be substantially parallel to each other and along the third surface. The plurality of dielectric plates are preferably arranged such that adjacent ones have a predetermined interval and are parallel to each other. What is necessary is just to determine this predetermined space | interval so that air can fully distribute | circulate with respect to the plant which should supply air via a flying organism removal apparatus. For example, the distance between adjacent dielectric plates may be determined according to the type of plant to which air is to be supplied.

  The third surface described above is a virtual surface and is located at a position different from the first surface and the second surface described above. The third surface is a virtual surface that characterizes the overall shape of the plurality of dielectric plates. Specifically, first, the shape of each of the plurality of dielectric plates is specified by the shape of one line. This can define a single line by defining the center of the dielectric plate in a plane perpendicular to the longitudinal direction of the dielectric plate and connecting the center along the longitudinal direction of the dielectric plate. In this way, one line characterizing each of the plurality of dielectric plates can be determined. In addition, the shape of the line for characterizing each shape of the plurality of dielectric plates does not need to be a strict shape indicating the dielectric plate, but an average that can show an outline of each of the plurality of dielectric plates. Any shape is acceptable.

  A third surface can then be defined by identifying one surface that includes a line characterizing the shape of each of the plurality of dielectric plates. It is not necessary to specify a strict surface in which all of these lines are always included in the specification of the third surface, and one approximately included surface may be set as the third surface.

  Further, the third surface is disposed at a position separated from the first surface and the second surface by a predetermined distance. The shape of each of the plurality of dielectric plates is determined, or the plurality of dielectric plates are arranged so that the plurality of dielectric plates do not shadow the plant to which air is supplied via the flying organism removing device. It is preferable. In other words, it is preferable that the plurality of dielectric plates are arranged in such a manner that the plurality of dielectric plates do not block light from the plants. Each of the plurality of dielectric plates is disposed so that air can pass between each of the plurality of dielectric plates. The interval between each of the plurality of dielectric plates may be such that air can be sufficiently supplied to a plant to which air is supplied via the flying organism removing device.

  In particular, when the first surface, the second surface, and the third surface are planar, the first surface, the second surface, and the third surface are arranged so as to be substantially parallel. Preferably it is done. Note that only the relationship between the first surface, the second surface, and the third surface is parallel, and the plurality of first conductors, the second conductors, and the plurality of dielectric plates are all connected. There is no need to be parallel. For example, even if the longitudinal direction of the plurality of first conductors is the horizontal direction and the longitudinal direction of the plurality of dielectric plates is the vertical direction, the first surface and the third surface should be substantially parallel. That's fine. Further, the longitudinal direction of the plurality of first conductors and the longitudinal direction of the plurality of dielectric plates are oriented in any direction as long as the first surface and the third surface are substantially parallel. Also good.

The flying organism removing apparatus according to the present invention is
The dielectric is a dielectric network formed in a network by a dielectric material,
The dielectric network is disposed along a predetermined third surface different from the first surface and the second surface;
It is preferable that the third surface is separated from the first surface and the second surface by a predetermined distance.

  The above-described dielectric is a dielectric network formed in a mesh shape with a dielectric material. The mesh is formed by knitting or bending a dielectric wire, or all or part of the dielectric mesh is formed by forming a hole in a dielectric material, for example, a plate-like material. It is sufficient if it is formed so that it can be visually recognized as a net. The size of one mesh may be determined according to the type of creature that can fly. Also, it is not necessary for all mesh sizes to be the same. The shape of the mesh is preferably a substantially square shape or a substantially rhombus shape, but may be other polygonal shapes.

  The dielectric network is disposed along the third surface. That is, the third surface is defined by the entire dielectric network. The third surface is a virtual surface and is a surface different from the first surface and the second surface described above. Further, the third surface is disposed so as to be separated from the first surface and the second surface by a predetermined distance. Note that the distance between the third surface and the first surface is not necessarily the same as the distance between the third surface and the second surface, and the third surface is not limited to the first surface or the second surface. What is necessary is just to arrange | position away from a surface.

  By doing so, it is preferable that the electric field strength generated by the dielectric polarization of the dielectric network body be shaped so as to vary depending on the position and disposed. In this way, by generating an electric field whose electric field intensity varies depending on the position (uneven electric field, non-uniform field), when the flying creature is charged, the Coulomb force is applied to the flying creature. If the flying creature is electrically neutral, the flying creature can be subjected to electrostatic induction to exert a gradient force. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing so, it is possible to accurately capture flying creatures by the electric field generated by the dielectric polarization of the dielectric network.

  Furthermore, by appropriately determining the size of the mesh of the dielectric mesh body, it is possible to prevent the movement of an object larger than the flying organism, for example, plant leaves and dust, by the dielectric mesh body. It can exclude so that it may not contact 1 conductor and 2nd conductor.

The flying organism removing apparatus according to the present invention is
Including at least two housing openings facing each other so that air can flow, and supporting the first conductor, the second conductor, and the dielectric,
The first surface, the second surface, and the third surface are preferably substantially parallel to at least one of the two housing openings.

  The flying organism removing apparatus according to the present invention includes a housing. This casing is formed with at least two casing openings. The at least two housing openings are formed so that air can flow, and are formed to face each other. In particular, it is preferable that two housing openings are formed so as to be substantially parallel to each other. In addition, the first conductor, the second conductor, and the dielectric described above are supported by the housing. By doing so, the first conductor, the second conductor, and the dielectric are disposed between at least two housing openings.

  Furthermore, the first surface, the second surface, and the third surface described above are substantially parallel to at least one housing opening of at least two housing openings. Note that the phrase “substantially parallel to the casing opening” means that the surface that can be defined by the edge of the casing opening is substantially parallel to the casing opening.

  By doing in this way, discharge can be produced with respect to the flying organism which moves on the flow of the air which distribute | circulates over at least 2 housing | casing opening, and a flying organism can be removed exactly.

The flying organism removing apparatus according to the present invention is
Each of the plurality of dielectric plates has a convex curved surface protruding in a direction perpendicular to the longitudinal direction, and
Each of the plurality of dielectric plates is preferably arranged such that the convex curved surface is oriented in a direction perpendicular to the third surface.

  Each of the plurality of dielectric plates has a convex curved surface protruding in a direction perpendicular to the longitudinal direction. As described above, the plurality of dielectric plates need only have a plate shape and can determine the longitudinal direction, and do not necessarily have a long shape. The longitudinal direction indicates the direction in which the dielectric plate is formed the longest. The convex curved surface is formed so as to protrude, and the outer shape may be formed by a curved surface. Each of the plurality of dielectric plates is disposed such that the convex curved surface is directed in a direction perpendicular to the third surface described above.

  As described above, each of the plurality of dielectric plates has a shape having a convex curved surface, so that electric fields (inhomogeneous electric field, non-uniform field) having different strengths depending on positions are generated by the dielectric polarization of the plurality of dielectric plates. Can do. By generating such an electric field, when a flying creature is charged, the Coulomb force can be exerted on the flying creature, and the flying creature is electrically neutral. In some cases, a gradient force can be exerted by causing electrostatic induction in a flying creature. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing so, it is possible to accurately capture flying creatures by the electric field generated by the dielectric polarization of the dielectric.

  In addition, since each of the plurality of dielectric plates has a shape having a convex curved surface, when air is supplied to the plant through the flying creature removing device, the air flow is bent, the air is rotated, Can produce vortex. By bending the air flow or giving a rotational component to the air flow, the electric field generated by the first conductor and the second conductor described above and the electric field generated by the dielectric polarization of the dielectric are effectively present. It is possible to increase the chances of a creature that can fly in the area to be captured, and to capture or remove the creature that can fly accurately. In addition, it is possible to increase the chance of living creatures that can fly in the region where the electric field exists effectively without increasing the size of the first and second conductors and the dielectric, so that the device can be made thinner. Can be downsized.

  The dielectric plate preferably has a substantially arc-shaped cross section along a direction perpendicular to the longitudinal direction. Furthermore, the cross-section along the direction perpendicular to the longitudinal direction is preferably a substantially semicircle. That is, it is preferable that the dielectric plate has a semicylindrical shape. By doing in this way, processing of a dielectric plate can be made easy and arrangement | positioning can be made easy.

The flying organism removing apparatus according to the present invention is
It is preferable that at least a part of one of the first conductor or the plurality of second conductors is covered with a dielectric material.

  One of the first conductor or the second conductor is covered with a dielectric material. It is not necessary for all of the conductors to be covered with a dielectric material, as long as at least a portion is covered with a dielectric material. For example, the first conductor or the second conductor is covered with a dielectric material. For example, the first conductor or the second conductor is covered with a cylindrical dielectric, or a semi-cylindrical shape. Some of the dielectrics cover the first conductor and the second conductor.

  By doing in this way, it becomes unnecessary to separately arrange a dielectric separately from the first conductor and the second conductor, and the dielectric and the conductor can be handled integrally. Assembly and handling can be facilitated.

The flying organism removing apparatus according to the present invention is
The first conductor is at least partly covered with a dielectric material, and is a plurality of linear or plate-like dielectric covered conductors,
The plurality of dielectric coated conductors are arranged so as to be substantially parallel to each other,
The plurality of dielectric coated conductors are arranged along a predetermined fourth surface,
The second conductor is a plurality of linear or plate-like second conductors,
The plurality of second conductors are arranged to be substantially parallel to each other,
The plurality of second conductors are arranged along a second surface having a predetermined shape,
The fourth surface and the second surface are preferably separated by the one distance.

  The first conductor described above is at least partially covered with a dielectric material, and this is called a dielectric coated conductor. There are a plurality of dielectric coated conductors, and they have a linear or plate shape. The plurality of dielectric coated conductors are arranged so as to be substantially parallel to each other. The plurality of dielectric coated conductors do not have to be linear or rectangular, and may be arranged in a certain shape. The plurality of dielectric coated conductors only need to be arranged at positions translated from each other.

  The intervals between the plurality of dielectric coated conductors allow sufficient air to flow through the plant to which air is supplied via the flying organism removing device, depending on the type of plant and the type of flying organism to be removed. It should be determined to the extent that it can be done. Further, the interval between the plurality of dielectric coated conductors is such that the plurality of dielectric coated conductors are not shaded against the plant to which air is supplied via the flying organism removing device, and is exposed to light. It is preferable to determine appropriately according to the type and the type of flying organism to be removed.

  Further, the plurality of dielectric coated conductors are arranged along the fourth surface. The fourth surface is a virtual surface and is a virtual surface that characterizes the overall shape of the plurality of dielectric coated conductors. Specifically, first, the shape of each of the plurality of dielectric coated conductors is specified by the shape of one line. This can define a single line by defining the center of the dielectric coated conductor in a plane perpendicular to the longitudinal direction of the dielectric coated conductor and connecting the center along the longitudinal direction of the dielectric coated conductor. In this way, one line characterizing each of the plurality of dielectric coated conductors can be determined. In addition, the shape of the line for characterizing each shape of the plurality of dielectric coated conductors does not have to be a strict shape indicating the dielectric coated conductor, and an outline of each of the plurality of dielectric coated conductors can be shown. Any average shape may be used.

  A fourth surface can then be defined by identifying one surface such that a line characterizing the shape of each of the plurality of dielectric coated conductors is approximately included. It is not necessary to specify a strict surface in which all of these lines are always included in the specification of the fourth surface, and it is only necessary that one substantially included surface is the fourth surface.

  For example, when each of the plurality of dielectric coated conductors is linear and these are juxtaposed so as to be parallel to each other, each of the plurality of dielectric coated conductors can be specified by a straight line. . Further, since the plurality of dielectric coated conductors are juxtaposed in parallel to each other, the plane including these straight lines is one plane, and the fourth plane is the one plane.

  The shape of the fourth surface described above may be any shape as long as it can be defined in a certain shape such as a flat surface or a spherical surface, and may be appropriately determined according to the shape of the place where the flying creature removing device is installed. . The plurality of dielectric coated conductors only have to be arranged along the fourth surface.

  The second conductor described above is a second conductor having a linear or plate shape. The plurality of second conductors are arranged along the second surface. The second surface may be specified in the same manner as described above. It is preferable that the fourth surface and the second surface described above are separated by one distance. In particular, when both the fourth surface and the second surface have a planar shape, it is preferable that the fourth surface and the second surface are arranged so as to be substantially parallel.

  Note that only the relationship between the fourth surface and the second surface is parallel, and it is not necessary for the plurality of dielectric coated conductors and the plurality of second conductors to be parallel. For example, even if the longitudinal direction of the plurality of dielectric coated conductors is the horizontal direction and the longitudinal direction of the plurality of second conductors is the vertical direction, the fourth surface and the second surface are substantially parallel. I just need it. Further, the longitudinal direction of the plurality of dielectric coated conductors and the longitudinal direction of the plurality of second conductors are oriented in any direction as long as the fourth surface and the second surface are substantially parallel. May be.

  By doing this, it is possible to remove the creatures that can fly by giving a force by an electric field accurately to the creatures that can fly, or causing the creatures that can fly precisely to discharge. Since the dielectric and the conductor can be handled integrally, the assembly and handling of the flying organism removing apparatus can be facilitated.

The flying organism removing apparatus according to the present invention is
The first conductor is a dielectric coated conductor that is at least partially covered with a dielectric material and formed in a mesh shape;
The dielectric coated conductor is formed along a predetermined fourth surface,
The second conductor is a plurality of linear or plate-like second conductors,
The plurality of second conductors are arranged to be substantially parallel to each other,
The plurality of second conductors are arranged along a predetermined second surface,
The fourth surface and the second surface are preferably separated by the one distance.

  The first conductor described above is at least partially covered with a dielectric material, and this is called a dielectric coated conductor. The dielectric coated conductor is formed in a mesh shape. The mesh is formed by knitting or bending a conductive wire covered with a dielectric material, or all or part of the dielectric covered conductor is formed by a conductive material covered with a dielectric material. For example, it may be formed integrally by forming a hole in a plate-like material and finally formed so as to be visually recognized as a mesh shape. The size of one mesh may be determined according to the type of creature that can fly. Also, it is not necessary for all mesh sizes to be the same. The shape of the mesh is preferably a substantially square shape or a substantially rhombus shape, but may be other polygonal shapes.

  The dielectric coated conductor is disposed along the fourth surface. That is, the fourth surface is defined by the entire dielectric coated conductor. The fourth surface is a virtual surface and is a surface different from the second surface. Further, the fourth surface is disposed so as to be separated from the second surface by a predetermined distance.

  In this way, it is preferable that the electric field strength generated by the dielectric polarization of the dielectric coated conductor is different in shape depending on the position and is arranged. In this way, by generating an electric field whose electric field intensity varies depending on the position (uneven electric field, non-uniform field), when the flying creature is charged, the Coulomb force is applied to the flying creature. If the flying creature is electrically neutral, the flying creature can be subjected to electrostatic induction to exert a gradient force. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing so, it is possible to accurately capture flying creatures by the electric field generated by the dielectric polarization of the dielectric coated conductor.

  Furthermore, by appropriately determining the size of the mesh of the dielectric coated conductor, it is possible to prevent the movement of an object larger than the flying organism, for example, a plant leaf or dust, by the dielectric coated conductor. It can be excluded so as not to contact the conductor.

The flying organism removing apparatus according to the present invention is

  The flying organism removing apparatus according to the present invention includes a housing. This casing is formed with at least two casing openings. The at least two housing openings are formed so that air can flow, and are formed to face each other. In particular, it is preferable that two housing openings are formed so as to be substantially parallel to each other. Further, the above-described dielectric coated conductor and the second conductor are supported by the casing. By doing so, the dielectric coated conductor and the second conductor are disposed between at least two housing openings.

  Further, the fourth surface and the second surface described above are substantially parallel to at least one of the two housing openings. Note that the phrase “substantially parallel to the casing opening” means that the surface that can be defined by the edge of the casing opening is substantially parallel to the casing opening.

  By doing in this way, discharge can be produced with respect to the flying organism which moves on the flow of the air which distribute | circulates over at least 2 housing | casing opening, and a flying organism can be removed exactly.

The plant protection device according to the present invention comprises:
A plant placement area where the plant is placed;
And a surrounding portion surrounding the plant placement area,

The kind of plant is not ask | required. The go portion surrounds the plant placement area. The go portion is made of a member that can transmit visible light to the extent necessary for plant growth and survival. The surrounding portion is provided with a place where air can flow. The air should just be able to distribute | circulate air to the extent required for the growth and survival of a plant. The place where the air can circulate is provided with the above-described flying organism removing apparatus. By doing in this way, the flying organism can be removed from the air, and air suitable for plant growth and survival can be supplied.

The plant protection device according to the present invention comprises:
It is preferable that the dielectric, the first conductor, and the second conductor are arranged in this order toward the plant placement area.

  By disposing the dielectric, the first conductor, and the second conductor in this manner, first, it is possible to make it difficult for the flying creature to move by the electric field generated by the dielectric polarization of the dielectric. Movable organisms can be captured. In addition, even when the electric field generated by the dielectric polarization of the dielectric material cannot be captured, the electric field generated from the first conductor and the second conductor causes a discharge to the flying organism. Thus, the flying organisms can be removed, so that the removal of the flying organisms can be ensured, and air suitable for plant growth and survival can be supplied to the plants.

The plant protection device according to the present invention comprises:
What is arrange | positioned so that the said convex curve may face in the opposite direction with respect to the said plant arrangement | positioning area is preferable.

  The convex curved surface can be used to bend the flow of air, rotate the air, or generate vortex. In this way, by bending the air flow or adding a rotational component to the air flow, the opportunity for flying creatures to exist in the area where the electric field exists effectively can be increased, and the flight can be performed accurately. Increase opportunities to remove movable organisms.

In the surrounding portion, at least one flow opening for supplying air to the plant arranged in the plant arrangement area is formed,
The flying organism removing device is attached so as to cover the at least one flow opening,

It is possible to prevent organisms from reaching plants.

  It is preferable that the dielectric coated conductor and the second conductor are arranged in this order toward the plant placement area.

  By doing in this way, first, it is possible to make it difficult to move the flying creature by the electric field generated by the dielectric polarization of the dielectric coated conductor, and it is possible to capture the flying creature. In addition, even if the electric field generated by the dielectric polarization of the dielectric coated conductor cannot be captured, the electric field generated from the second conductor causes a discharge to the flying organism and causes the flight. Since possible organisms can be removed, removal of flying creatures can be ensured, and air suitable for plant growth and survival can be supplied to the plants.

In the surrounding portion, at least one flow opening for supplying air to the plant arranged in the plant arrangement area is formed,
The flying organism removing device is attached so as to cover the at least one flow opening,

It is possible to prevent organisms from reaching plants.

  A static electric field is applied to flying organisms such as spores of plant pathogenic bacteria and / or small pests, and the flying organisms are captured by applying an electrostatic field or are killed by discharge. In this way, it is possible to remove flying organisms and prevent plant pest damage.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

In addition, this FIG. 3 showed what the flying organism removal apparatus 100 was attached to the opening 34a of the front wall 32a of the plant protection apparatus 10 mentioned above as an example. As shown in FIG. 3, the flying organism removing apparatus 100 is attached to the outer surface of the front wall 32a so as to cover the opening 34a. As described above, when the flying organism removing device 100 is attached to the plant protection device 10 (not shown), the back surface 168b of the flying organism removing device 100 is aligned with the opening 34a of the plant protection device 10. In FIG. 3, the left direction of the drawing is the outside of the plant protection device 10, the right direction of the drawing is the inside of the plant protection device 10, and there is a plant arrangement area 20 (not shown).

<First conductor 110>
The first conductor 110 of the flying organism removing apparatus 100 shown in FIG. 3 has two sets of an outer one (the left side in the drawing) and an inner one (the right side in the drawing). Hereinafter, the outer one is referred to as the first conductor 110a, and the inner one is referred to as the first conductor 110b. The first conductor 110a includes nine first conductors 112a. The first conductor 110b includes nine first conductors 112b. The broken lines shown in FIG. 3 indicate the first surface 114a that characterizes the overall shape of the nine first conductors 112a and the first surface 114b that characterizes the entire shape of the nine first conductors 112b. This is a virtual surface, not a real surface. The first surfaces 114a and 114b will be described later. As described above, the nine first conductors 112a and the nine first conductors 112b are electrically connected to each other by an electric wire (not shown) at the side portion 162a or 162b of the housing 150. Connected.

  In FIG. 3, a cross section of nine first conductors 112a and nine first conductors 112b is drawn. Each of the nine first conductors 112a and each of the nine first conductors 112b has a substantially linear shape, and is in a horizontal direction (a direction perpendicular to the paper surface of FIG. 3). It is a long conductive wire extending straight. The cross-sectional shapes of the first conductors 112a and 112b are substantially circular.

  Each of these nine first conductors 112a is arranged in a horizontal direction (a direction perpendicular to the paper surface of FIG. 3). The nine first conductors 112a are spaced apart from each other, and are arranged so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. Similarly, each of the nine first conductors 112b is also arranged in the horizontal direction (direction perpendicular to the paper surface of FIG. 3). Each of the nine first conductors 112b is also arranged so as to be spaced apart from each other so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. As described above, by disposing each of the nine first conductors 112a and 112b so as to be separated from each other, air can be sufficiently supplied to the plant protection device 10, and the nine first conductors 112a and 112b can be supplied. Since the shadow caused by the single conductors 112a and 112b can be reduced, it is possible not to block the light irradiated to the plant protection device 10.

  Note that the shape of each of the nine first conductors 112a and the shape of each of the nine first conductors 112b are not limited to being linear, and can maintain a certain shape. For example, it may have a curved shape along a certain curve.

  The nine first conductors 112a constituting the first conductor 110a are arranged along the vertical direction (vertical direction on the paper surface of FIG. 3). That is, the nine first conductors 112a are arranged along the first surface 114a.

  The method for specifying the first surface 114a may be performed according to the following procedure.

  First, the shape of each of the nine first conductors 112a is specified by the shape of one line. This is by defining the center of the first conductor 112a in a plane perpendicular to the longitudinal direction of one first conductor 112a and connecting the center along the longitudinal direction of the first conductor 112a, One line can be defined for one first conductor 112a. In this way, it is possible to determine one line characterizing each of the nine first conductors 112a. In the present embodiment, since each of the nine first conductors 112a has a substantially straight shape extending straight as described above, each of the nine first conductors 112a. The line characterizing is a straight line.

  The first surface 114a can then be defined by identifying one surface that approximately includes a line for characterizing the shape of each of the nine first conductors 112a. The first surface 114a need not be specified as a strict surface in which all of these lines are always included, and one approximately included surface may be used as the first surface 114a. In the present embodiment, since the lines for characterizing the shapes of the nine first conductors 112a are straight lines as described above, the shape of the first surface 114a is one plane. It becomes.

  The nine first conductors 112b constituting the first conductor 110b are also arranged along the vertical direction (vertical direction on the paper surface of FIG. 3). That is, the nine first conductors 112b are arranged along the first surface 114b. The first surface 114b can be specified by the same method as that for the first surface 114a.

  As described above, the nine first conductors 112a constituting the first conductor 110a and the nine first conductors 112b constituting the first conductor 110b are arranged along the vertical direction. Therefore, the first surface 114a and the first surface 114b are parallel to each other.

  In the example shown in FIG. 3, the first surface 114a characterizing the overall shape of the nine first conductors 112a is a flat surface, and the overall shape of the nine first conductors 112b is the same. Although the case where the first surface 114b to be characterized is also a flat surface is shown, the first surfaces 114a and 114b are not limited to being a flat surface, and may be curved surfaces. The nine first conductors 112a and the nine first conductors 112b may be arranged along a certain surface.

<Second conductor 120>
The second conductor 120 of the flying organism removing apparatus 100 illustrated in FIG. 3 includes nine second conductors 122. The broken line shown in FIG. 3 is the second surface 124 that characterizes the overall shape of the nine second conductors 122, which is a virtual surface and not a substantial surface. The second surface 124 will be described later. These nine second conductors 122 are electrically connected to each other by an electric wire (not shown).

  In FIG. 3, cross sections of nine second conductors 122 are drawn. Each of the nine second conductors 122 is a long conductive wire having a substantially linear shape and extending straight in the horizontal direction (direction perpendicular to the paper surface of FIG. 3). The cross-sectional shape of the second conductor 122 is substantially circular.

  Each of these nine second conductors 122 is arranged in a horizontal direction (a direction perpendicular to the paper surface of FIG. 3). Each of the nine second conductors 122 is spaced apart from each other and arranged so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. As described above, each of the nine second conductors 122 is arranged so as to be spaced apart from each other, so that air can be sufficiently supplied to the plant protection device 10, and the nine second conductors can be supplied. Since the shadow caused by the conductor 122 can be reduced, it is possible to prevent the light irradiating the plant protection device 10 from being blocked.

  Note that the shape of each of the nine second conductors 122 is not limited to a linear shape, and may be any shape that can maintain a constant shape, for example, a curve along a constant curve. It may have a shape.

  The nine second conductors 122 constituting the second conductor 120 are arranged along the vertical direction (the vertical direction of the paper surface of FIG. 3). That is, the nine second conductors 122 are arranged along the second surface 124 that is substantially parallel to the first surface 114a or 114b described above.

  The second surface 124 can be specified by the same method as the first surfaces 114a and 114b. The second surface 124 is parallel to the above-described first surfaces 114a and 114b, and is located at a predetermined distance from the first surfaces 114a and 114b. This predetermined distance does not cause discharge when only the nine first conductors 112a and 112b and the nine second conductors 122 are present, but the nine first conductors 112a and 112b When there is a flying creature between 112b and the nine second conductors 122, the distance is set such that a discharge can be generated. Note that the nine second conductors 122 need only be roughly arranged along the second surface 124, and need not be arranged so as to be included in the second surface 124. That is, the nine second conductors 122 may be arranged so that the entirety of the nine second conductors 122 can be visually recognized as constituting the second surface 124.

  In the example illustrated in FIG. 3, the second surface 124 that characterizes the entire shape of the nine second conductors 122 is a flat surface. However, the second surface 124 is a flat surface. It is not limited to a certain case, and may be a curved surface. The nine second conductors 122 only need to be arranged along a certain surface.

  As shown in FIG. 3, the vertical positions of the first conductors 112a and 112b (vertical direction in FIG. 3) and the vertical positions of the second conductors 122 are staggered. The nine first conductors 112a and 112b and the second conductor 122 are preferably arranged. By doing in this way, it can be easy to produce the electric field from which intensity differs in a position, and it can make it easy to exert Coulomb force and gradient force on the creature which can fly.

  As will be described later, the first conductors 110 a and 110 b and the second conductor 120 described above are electrically connected to a power source 130. By doing so, the first conductors 110a and 110b have the first potential, and the second conductor 120 has the second potential higher than the first potential. In particular, the first conductors 110a and 110b are preferably grounded and have a potential of zero.

  In addition, the above-mentioned distance between the first surface 114a and the second surface 124 and the distance between the first surface 114b and the second surface 124 are “one distance” for the flying creature. The distance may be any distance that can cause an accurate discharge, preferably 0.1 to 3 cm, more preferably 0.3 to 2 cm, and still more preferably 0.5 to 1 cm.

  Moreover, it is preferable that there is no dielectric other than air between the first conductors 110a and 110b and the second conductor 120. The arrangement of the first conductor 110 and the second conductor 120 may be alternately arranged, or only the single first conductor 110 and the single second conductor 120 may be arranged. Good.

<Power supply 130>
The power supply 130 has a plus terminal and a minus terminal that can output a predetermined DC voltage.

  Each of the nine first conductors 112a constituting the first conductors 110a and 110b and each of the nine first conductors 112b are connected to the negative terminal of the power supply 130. In the present embodiment, the minus terminal is grounded. Each of the nine second conductors 122 constituting the second conductor 120 is connected to the positive terminal of the power supply 130.

  The DC voltage applied to the first conductors 110a and 110b and the second conductor 120 is determined by the distance between the first surface and the second surface, the distance from the dielectric 140, which will be described later, and the amount of air passing therethrough. What is necessary is just to decide suitably by etc. For example, any voltage may be used as long as a high voltage can be applied to a flying organism such as a pest and a discharge can be caused to the flying organism. Specifically, the DC voltage applied to the first conductors 110a and 110b and the second conductor 120 is preferably 1 to 40 kV, more preferably 3 to 30 kV, and even more preferably 5 to 20 kV. When the DC voltage to be applied is 1 to 40 kV, it is preferable because a living thing that can fly between the first conductor and the second conductor can be removed. In addition, when the DC voltage to be applied is too low, it is not preferable because there is a possibility that dielectric polarization is not generated in the flying creature.

  In this embodiment, a DC high voltage generator is used as a power source. By doing so, a constant high voltage can be applied to the first conductors 110a and 110b and the second conductor 120, and flyable organisms such as pests are removed by discharge, thereby protecting the plant. Intrusion into the plant placement area 20 of the device 10 can be prevented.

The plant protection device 10 described above may be naturally ventilated or forcedly ventilated. The wind speed in the case of forced ventilation is the distance between the first conductors 110a and 110b and the second conductor 120, the voltage applied to the first conductors 110a and 110b and the second conductor 120, and a dielectric that will be described later. What is necessary is just to determine by the position of. For example, 1 to 1000 m ³ / hr per 1 m ² can be given as an example for the openings 34 a and 34 b of the plant protection device 10.

<Dielectric 140>
As shown in FIG. 3, the dielectric 140 is attached to the outermost side of the flying organism removing apparatus 100. The dielectric 140 is composed of eight dielectric plates 142 having a plate-like dielectric property. The broken line shown in FIG. 3 is a third surface 144 that characterizes the overall shape of the eight dielectric plates 142, which is a virtual surface and not a substantial surface. The third surface 144 will be described later.

  The dielectric 140 may be anything that does not conduct electricity, that is, a so-called insulator. Examples of the material of the dielectric 140 include vinyl chloride, polyethylene, polypropylene, urethane, polyester, rayon, cellulose, rubber, and the like.

  3 and 4, cross sections of the eight dielectric plates 142 are drawn. The cross-sectional shape of the dielectric plate 142 is a substantially semicircular arc. As shown in FIGS. 3 and 4, each of the eight dielectric plates 142 has a long shape extending straight in the horizontal direction (direction perpendicular to the paper surface of FIG. 3). FIG. 4 is a perspective view showing one dielectric plate 142. Each of the eight dielectric plates 142 has a semi-cylindrical shape extending straight in the horizontal direction. By adopting such a shape, the vertical direction can be reduced and the surface area can be increased. Since it can be reduced in the vertical direction, the thickness of the flying organism removing apparatus 100 can be reduced, and the shadow generated by the eight dielectric plates 142 can be reduced, so that the light irradiating the plant protection apparatus 10 is not blocked. Can be. In addition, the intensity of the electric field generated by the dielectric polarization of the dielectric plate 142 can be made more nonuniform. Furthermore, since the surface area of the dielectric plate 142 can be increased, an area where the electric field generated by the dielectric polarization of the dielectric plate 142 can be exerted on the flying creature can be expanded.

  Each of these eight dielectric plates 142 is arranged in a horizontal direction (a direction perpendicular to the paper surface of FIG. 3). Each of the eight dielectric plates 142 is arranged so as to be spaced apart from each other so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. In this way, by arranging the eight dielectric plates 142 to be spaced apart from each other, it is possible to make it difficult to block the light irradiated to the plant protection device 10.

  Note that the shape of each of the eight dielectric plates 142 is not limited to a long shape that extends straight, and may be any shape that can maintain a certain shape, for example, along the longitudinal direction. It may have a curved shape.

  The eight dielectric plates 142 constituting the dielectric 140 are arranged along the vertical direction (vertical direction on the paper surface of FIG. 3). That is, the eight dielectric plates 142 are arranged along the third surface 144.

  The method for specifying the third surface 144 may be performed by the following procedure.

  First, the shape of each of the eight dielectric plates 142 is specified by the shape of one line. This defines a center of the dielectric plate 142 in a plane perpendicular to the longitudinal direction of the dielectric plate 142, and connects the center along the longitudinal direction of the dielectric plate 142 to define a single line. In this way, one line characterizing each of the eight dielectric plates 142 can be determined. In the present embodiment, since each of the eight dielectric plates 142 has a semi-cylindrical shape extending straight as described above, a line characterizing each of the eight dielectric plates 142 is a straight line. It becomes.

  A third surface 144 can then be defined by identifying one surface that approximately includes a line characterizing the shape of each of the eight dielectric plates 142. The third surface 144 is not necessarily specified as a strict surface that always includes all of these lines, and the roughly included one surface may be the third surface 144. In the present embodiment, since the lines for characterizing the shapes of the eight dielectric plates 142 are straight lines as described above, the shape of the third surface 144 is one plane.

  As shown in FIGS. 3 and 4, the shape of the cross section of each of the eight dielectric plates 142 is a substantially semicircular arc shape, but the shape of the cross section is toward the outside of the plant protection device 10 ( It may be a convex curve that protrudes (leftward in FIG. 3). That is, each of the eight dielectric plates 142 is arranged such that the convex curved surfaces of the eight dielectric plates 142 protrude in a direction perpendicular to the longitudinal direction of the dielectric plates 142.

  In this way, each of the eight dielectric plates 142 has a shape having a convex curved surface, so that electric fields (inhomogeneous electric field and non-uniform field) having different strengths depending on positions can be applied to the dielectric polarization of the eight dielectric plates 142. Can be generated. By generating such an electric field, when a flying creature is charged, the Coulomb force can be exerted on the flying creature, and the flying creature is electrically neutral. In some cases, a gradient force can be exerted by causing electrostatic induction in a flying creature. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing so, it is possible to accurately capture flying creatures by the electric field generated by the dielectric polarization of the eight dielectric plates 142.

  In addition, since each of the eight dielectric plates 142 has a shape having a convex curved surface, as shown by the arrow formed by the curve in FIG. 3, when supplying air to the plant through the flying organism removing device, The convex curved surface can be used to bend the air flow, rotate the air, or generate vortex. By bending the air flow or applying a rotational component to the air flow, the electric fields generated by the nine first conductors 112a and 112b and the nine second conductors 122 described above, It is possible to increase the chances of flying creatures in the region where the electric field generated by the dielectric polarization of the eight dielectric plates 142 is effectively present, and to capture and remove the flying creatures accurately. be able to. Further, it is possible to fly to a region where an electric field is effectively present without increasing the nine first conductors 112a and 112b, the nine second conductors 122, and the eight dielectric plates 142. Since it is possible to increase the chance of living organisms, the device can be made thinner or smaller.

  The eight dielectric plates 142 constituting the dielectric 140 are arranged along the vertical direction (up and down direction on the paper surface of FIG. 3). That is, the eight dielectric plates 142 are arranged along the third surface 144 substantially parallel to the first surface 114a or 114b described above. The third surface 144 is located at a predetermined distance from the first surface 114a or 114b, and is substantially parallel to the first surface 114a or 114b and the second surface 124. The predetermined distance is that dielectric polarization occurs in the eight dielectric plates 142 by the electric fields generated by the first conductors 110a and 110b and the second conductor 120, and the electric fields can be effectively generated by the dielectric polarization. Any distance is sufficient. Effectively generating this electric field means that the movement of living creatures can be prevented by the electric field generated by dielectric polarization. As for the predetermined distance mentioned above, for example, this distance is preferably 3 cm or less, more preferably 0.3 to 2 cm, and further preferably 0.5 to 1 cm.

  It should be noted that the eight dielectric plates 142 need only be roughly arranged along the above-described third surface 144, and need not be arranged so as to be included in the third surface 144. In other words, the eight dielectric plates 142 may be arranged so that the entirety of the eight dielectric plates 142 can be visually recognized as constituting the third surface 144.

  In the example shown in FIG. 3, the third surface 144 characterizing the entire shape of the eight dielectric plates 142 is a flat surface, but the third surface 144 is not a flat surface but a curved surface. But you can. The eight dielectric plates 142 should just be arrange | positioned along a fixed surface.

  In the example shown in FIG. 3, the cross section of the dielectric plate 142 has a substantially semicircular arc shape. However, the electric field generated by the dielectric polarization of the dielectric plate 142 on a flyable organism such as a pest. Any shape can be used as long as the force can be applied to the flying creature such as a pest and the like and captured. However, the shape which can inhibit the discharge by the electric field produced by the 1st conductor 110a and 110b and the 2nd conductor 120 with respect to the creature which can fly is remove | excluded.

  The electric field generated by the dielectric polarization of the eight dielectric plates 142 constituting the dielectric 140 makes it difficult for the creatures that can fly to move and can be captured by the eight dielectric plates 142 and can fly. Living organisms can be removed. In addition, even if the flying organism cannot be captured by the electric field generated by the dielectric polarization of the dielectric 140, the nine first conductors 112a and 110b constituting the first conductors 110a and 110b 112b and the electric field generated from the nine second conductors 122 constituting the second conductor 120 can cause the dischargeable organisms to discharge and be removed. Biological removal can be ensured.

<Dielectric plates 242, 342, 442>
5a to 5c are perspective views showing second to fourth examples of the dielectric plate.

  The dielectric plate 242 of the second example shown in FIG. 5a, the dielectric plate 342 of the third example shown in FIG. 5b, and the dielectric plate 442 of the fourth example shown in FIG. 5c are the dielectric plates of the first example. Similar to 142, the cross-sectional shape is a substantially semicircular arc shape, and the entire shape has a long shape extending two straight. That is, the dielectric plates 242, 342, and 442 have a semi-cylindrical shape extending straight.

  On the convex surface of the dielectric plate 242, a plurality of grooves 244 are formed along the longitudinal direction of the dielectric plate 242. A plurality of recesses 344 are formed on the convex surface of the dielectric plate 342. By forming such a plurality of grooves 244 and a plurality of recesses 344 on the convex surface, the intensity of the electric field generated by the dielectric polarization of the eight dielectric plates 242 and 342 can be made more non-uniform. By generating such an electric field, a larger Coulomb force or a gradient force can be exerted on the flying creature, and the flying creature can be captured while making it more difficult to move.

  In addition, the plurality of grooves 244 and the plurality of recesses 344 can bend the flow of air flowing near the convex surfaces of the dielectric plates 242 and 342, rotate the air more, and cause more vortexes. Further, it is possible to further increase the chances of causing a flying creature to exist in a region where the electric field is effectively present, and it is possible to capture or remove the flying creature.

  Further, the dielectric plate 442 is formed from a dielectric material in a mesh shape, for example, a fiber shape. Even in this case, it is possible to generate an electric field with a non-uniform intensity, and to exert a greater Coulomb force or gradient force on the flying creature, further moving the flying creature. It is difficult to capture.

  Further, by forming the mesh, it is possible to improve air circulation, bend the air flow more greatly, rotate the air more, and generate more vortex.

  In the above-described flying organism removing apparatus 100, the first conductor is composed of two sets of nine first conductors 112a and nine first conductors 112b. But you can. What is necessary is just to adjust according to the kind of flying organism to remove, the kind of plant to protect, etc. In addition, the second conductor is only one set of nine second conductors 122, but this is also two or more sets depending on the type of flying organism to be removed, the type of plant to be protected, and the like. It may be. Further, in the flying organism removing apparatus 100, only one set of eight dielectric plates 142 is used as the dielectric, but this also depends on the type of flying organism to be removed, the type of plant to be protected, and the like. It may be more than a set.

As shown in FIG. 6, the flying organism removing apparatus 200 is attached to the outer surface of the front wall 32a so as to cover the opening 34a. When the flying organism removing device 200 is attached to the plant protection device 10 (not shown), the back surface 168b of the flying organism removing device 200 is aligned with the opening 34a of the plant protection device 10. In FIG. 6, the left direction of the drawing is the outside of the plant protection device 10, the right direction of the drawing is the inside of the plant protection device 10, and there is a plant arrangement area 20 (not shown). The arrows shown in FIG. 6 indicate the flow of air that flows in from the outside of the plant protection device 10 toward the inside through the flying organism removal device 200.

  The flying creature removing apparatus 200 includes a first conductor 110, a second conductor 120, and a power supply 130. The first conductor 110, the second conductor 120, and the power source 130 have the same configuration as that of the flying organism removing apparatus 100, and have the same functions, and thus description thereof is omitted. That is, the flying organism removing apparatus 200 is obtained by omitting the dielectric 140 from the flying organism removing apparatus 100. It is good also as such a structure according to the kind of plant arrange | positioned in the plant protection apparatus 10, the kind of flying organism which should be removed.

  In the above-described flying organism removing apparatus 200, the first conductor is composed of two sets of nine first conductors 112a and nine first conductors 112b. But you can. What is necessary is just to adjust according to the kind of flying organism to remove, the kind of plant to protect, etc. In addition, the second conductor is only one set of nine second conductors 122, but this is also two or more sets depending on the type of flying organism to be removed, the type of plant to be protected, and the like. It may be.

FIG. 7 is a cross-sectional view showing the flying organism removing apparatus 300. In addition, this FIG. 7 showed as an example the thing to which the flying organism removal apparatus 300 was attached to the opening 34a of the front wall 32a mentioned above similarly to the flying organism removal apparatus 100 of FIG. As shown in FIG. 7, the flying organism removing apparatus 300 is attached to the outer surface of the front wall 32a so as to cover the opening 34a. When the flying organism removing device 300 is attached to the plant protection device 10 (not shown), the back surface 168b of the flying organism removing device 300 is aligned with the opening 34a of the plant protection device 10. In FIG. 7, the left direction of the drawing is the outside of the plant protection device 10, the right direction of the drawing is the inside of the plant protection device 10, and the plant arrangement area 20 exists. The arrows shown in FIG. 7 indicate the flow of air that flows in from the outside of the plant protection apparatus 10 toward the inside through the flying organism removal apparatus 300.

  The flying creature removing apparatus 300 includes a first conductor 110, a second conductor 120, a power supply 130, and a dielectric 540. The ends of the first conductor 110, the second conductor 120, and the dielectric 540 are supported by the housing 150. Note that the first conductor 110, the second conductor 120, and the power source 130 have the same configuration as that of the flying organism removing apparatus 100 and have the same functions, and thus the description thereof is omitted.

<Dielectric 540>
As shown in FIG. 7, the dielectric 540 includes 16 plate-like dielectric plates 542 having dielectric properties. The broken line shown in FIG. 7 is a third surface 544 characterizing the overall shape of the 16 dielectric plates 542, which is a virtual surface and not a substantial surface. The third surface 544 will be described later.

  The dielectric 540 may be anything that does not conduct electricity, that is, a so-called insulator. Examples of the material of the dielectric 540 include vinyl chloride, polyethylene, polypropylene, urethane, polyester, rayon, cellulose, rubber, and the like.

  In FIG. 7, the cross sections of these 16 dielectric plates 542 are drawn. The cross-sectional shape of the dielectric plate 542 is substantially rectangular. As shown in FIG. 7, each of the 16 dielectric plates 542 has a long shape extending straight in the horizontal direction (direction perpendicular to the paper surface of FIG. 7). Each of the 16 dielectric plates 542 has an elongated thin flat plate shape extending straight in the horizontal direction. By adopting such a shape, the processing of the dielectric plate 542 can be facilitated, the arrangement of the dielectric plate 542 can be facilitated, and the flying organism removing apparatus 300 can be easily manufactured.

  Each of these 16 dielectric plates 542 is arranged in the horizontal direction (direction perpendicular to the paper surface of FIG. 7). The 16 dielectric plates 542 are spaced apart from each other and arranged so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. Thus, by arranging the 16 dielectric plates 542 apart from each other, it is possible to make it difficult to block the light irradiated to the plant protection device 10.

  Note that the shape of each of the 16 dielectric plates 542 is not limited to a long and straight shape, and may be any shape that can maintain a certain shape, for example, along the longitudinal direction. It may have a curved shape.

  The above-described method for specifying the third surface 544 may be performed by the following procedure.

  First, the shape of each of the 16 dielectric plates 542 is specified by the shape of one line. This defines a center of the dielectric plate 542 in a plane perpendicular to the longitudinal direction of the dielectric plate 542, and a single line can be defined by connecting the center along the longitudinal direction of the dielectric plate 542. In this way, one line characterizing each of the 16 dielectric plates 542 can be determined. In the present embodiment, each of the 16 dielectric plates 542 has an elongated thin flat plate shape that extends straight as described above. Therefore, the lines characterizing each of the 16 dielectric plates 542 are: It becomes a straight line.

  The third surface 544 can then be defined by identifying one surface that includes a line characterizing the shape of each of the 16 dielectric plates 542. The third surface 544 is not necessarily specified as a strict surface in which all of these lines are always included, and one approximately included surface may be used as the third surface 544. In the present embodiment, since the lines for characterizing the shapes of the 16 dielectric plates 542 are straight lines as described above, the third surface 544 is a single plane.

  As shown in FIG. 7, each of the 16 dielectric plates 542 is arranged so that the outer side (left side in FIG. 7) faces upward and the inner side (right side in FIG. 7) faces downward. By arranging in this way, the flow of the air passing between the dielectric plates 542 is changed from the top to the bottom. By doing so, the electric field generated by the nine first conductors 112a and 112b and the nine second conductors 122 and the electric field generated by the dielectric polarization of the 16 dielectric plates 542 are effective. It is possible to increase the chances of a creature that can fly in a region existing in the area, and to capture or remove the creature that can fly accurately.

  Moreover, by arranging in this way, air can be supplied to the plant protection device 10 without blocking the light entering the plant protection device 10.

  Note that the 16 dielectric plates 542 need only be roughly arranged along the above-described third surface 544, and need not be arranged so as to be included in the third surface 544. In other words, the 16 dielectric plates 542 may be arranged so that the entirety of the 16 dielectric plates 542 can be visually recognized as constituting the third surface 544.

In the example shown in FIG. 7, the third surface 544 characterizing the overall shape of the 16 dielectric plates 542 is a flat surface. However, the third surface 544 is not a flat surface but a curved surface. But you can. The 16 dielectric plates 542 may be arranged along a certain surface.
The electric field generated by the dielectric polarization of the 16 dielectric plates 542 constituting the dielectric 540 makes it difficult for the creatures that can fly to move and can be captured by the 16 dielectric plates 542 and can fly. Living organisms can be removed. In addition, even when the flying organism cannot be captured by the electric field generated by the dielectric polarization of the dielectric 540, the nine first conductors 112a and 110b constituting the first conductors 110a and 110b 112b and the electric field generated from the nine second conductors 122 constituting the second conductor 120 can cause the dischargeable organisms to discharge and be removed. Biological removal can be ensured.

  In the above-described flying organism removing apparatus 300, the first conductor is composed of two sets of nine first conductors 112a and nine first conductors 112b. But you can. What is necessary is just to adjust according to the kind of flying organism to remove, the kind of plant to protect, etc. In addition, the second conductor is only one set of nine second conductors 122, but this is also two or more sets depending on the type of flying organism to be removed, the type of plant to be protected, and the like. It may be. Further, in the flying organism removing apparatus 300, the dielectric is only one set of the 16 dielectric plates 542. However, this also depends on the type of flying organism to be removed, the type of plant to be protected, and the like. It may be more than a set.

In addition, this FIG. 8 showed as an example what the flying organism removal apparatus 400 was attached to the opening 34a of the front wall 32a mentioned above similarly to the flying organism removal apparatus 100 of FIG. As shown in FIG. 8, the flying organism removing apparatus 400 is attached to the outer surface of the front wall 32a so as to cover the opening 34a. When the flying organism removing device 400 is attached to the plant protection device 10 (not shown), the back surface 168b of the flying organism removing device 400 is aligned with the opening 34a of the plant protection device 10. In FIG. 8, the left direction of the drawing is the outside of the plant protection device 10, the right direction of the drawing is the inside of the plant protection device 10, and there is a plant arrangement area 20 (not shown). The arrows shown in FIG. 8 indicate the flow of air that flows in from the outside of the plant protection device 10 toward the inside through the flying organism removing device 400.

  The flying creature removing apparatus 400 includes a first conductor 210, a second conductor 220, a power supply 130, and a dielectric 140. The ends of the first conductor 210, the second conductor 220, and the dielectric 140 are supported by the housing 150. The power supply 130 and the dielectric 140 have the same configuration as that of the flying organism removing apparatus 100 and have the same functions, and thus description thereof is omitted here.

The first conductor 210 of the flying organism removing apparatus 400 shown in FIG. 8 includes two sets, an outer one (the left side in the drawing) and an inner one (the right side in the drawing). Hereinafter, the outer one is referred to as a first conductor 210a, and the inner one is referred to as a first conductor 210b. The first conductor 210a is composed of nine first conductive wires 212a, has the same configuration as the nine first conductors 112a described above, and a description thereof is omitted. The first conductor 210b includes nine first conductive plates 212b. The nine first conductive wires 212a and the nine first conductive plates 212b are electrically connected to each other by an electric wire (not shown) at the side portion 162a or 162b of the housing 150. Yes.

  The broken lines shown in FIG. 8 indicate a first surface 214a that characterizes the overall shape of the nine first conductive lines 212a and a first surface 214b that characterizes the overall shape of the nine first conductive plates 212b. This is a virtual surface, not a real surface. As described above, since the nine first conductive lines 212a have the same configuration as the nine first conductors 112a, the first shape characterizing the overall shape of the nine first conductive lines 212a. The surface 214a is also the same as the first surfaces 114a of the nine first conductors 112a, and the description thereof is omitted here. The first surface 214b will be described later.

  In FIG. 8, a cross section of nine first conductive lines 212a and nine first conductive plates 212b is depicted. The cross-sectional shape of the first conductive plate 212b is substantially rectangular, and the first conductive plate 212b is a long thin plate-like conductive member that extends straight in the horizontal direction (the direction perpendicular to the paper surface of FIG. 8). It is a board.

  The cross section of the first conductive plate 212b shown in FIG. 8 shows the width (horizontal direction) and thickness (vertical direction) of the first conductive plate 212b. As shown in FIG. 8, it is possible to prevent the flow of air flowing into the plant protection device 10 from being hindered by arranging the first conductive plate 212b so that the width direction thereof is in the horizontal direction.

  Each of these nine first conductive lines 212a is arranged in a horizontal direction (a direction perpendicular to the paper surface of FIG. 8). The nine first conductive lines 212a are spaced apart from each other, and are arranged so that the distance between adjacent ones is a predetermined length and substantially parallel to each other. Similarly, each of the nine first conductive plates 212b is also arranged in the horizontal direction (direction perpendicular to the paper surface of FIG. 8). Each of the nine first conductive plates 212b is also arranged so as to be spaced apart from each other so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. As described above, each of the nine first conductive wires 212a and each of the nine first conductive plates 212b are arranged so as to be separated from each other, thereby sufficiently supplying air to the plant protection device 10. And the shadow caused by each of the nine first conductive wires 212a and each of the nine first conductive plates 212b can be reduced, so that the light irradiating the plant protection device 10 can be reduced. It is also possible not to block.

  Note that the shape of each of the nine first conductive wires 212a and the shape of each of the nine first conductive plates 212b are not limited to a shape that extends straight, and a certain shape is maintained. For example, it may have a curved shape along a certain curve.

  The nine first conductive lines 212a constituting the first conductor 210 are arranged along the vertical direction (the vertical direction on the paper surface of FIG. 8). That is, the nine first conductive lines 212a are arranged along the first surface 214a. Similarly, the nine first conductive plates 212b constituting the first conductive plate 212b are arranged along the vertical direction (the vertical direction of the paper surface of FIG. 8). That is, the nine first conductive plates 212b are arranged along the first surface 214b substantially parallel to the first surface 214a.

  The above-described method for specifying the first surface 214b may be performed according to the following procedure.

  First, the shape of each of the nine first conductive plates 212b is specified by the shape of one line. This is by defining the center of the first conductive plate 212b in a plane perpendicular to the longitudinal direction of the first conductive plate 212b and connecting the center along the longitudinal direction of the first conductive plate 212b. One line can be defined for one first conductive plate 212b. Thus, one line characterizing each of the nine first conductive plates 212b can be determined. In the present embodiment, each of the nine first conductive plates 212b has a thin plate-like shape extending straight as described above, so that each of the nine first conductive plates 212b is The characterizing line is a straight line.

  Then, the first surface 214b can be defined by specifying one surface that roughly includes a line for characterizing the shape of each of the nine first conductive plates 212b. The first surface 214b need not be specified as a strict surface in which all of these lines are always included, and one approximately included surface may be used as the first surface 214b. In the present embodiment, since the lines for characterizing the shapes of the nine first conductive plates 212b are straight lines as described above, the shape of the first surface 214b is one plane. It becomes.

  In the example shown in FIG. 8, the first surface 214a that characterizes the overall shape of the nine first conductive lines 212a is a flat surface, and characterizes the entire nine first conductive plates 212b. Although the case where the first surface 214b is a plane is shown, the surfaces 214a and 214b are not limited to being a plane, and may be curved surfaces. The nine first conductive wires 212a and the nine first conductive plates 212b only need to be arranged along a certain surface.

<Second conductor 220>
The second conductor 220 of the flying organism removing apparatus 400 shown in FIG. 8 includes nine second conductive plates 222. The broken line shown in FIG. 8 is the second surface 224 that characterizes the overall shape of the nine second conductive plates 222, which is a virtual surface and not a substantial surface. The second surface 224 will be described later. The nine second conductive plates 222 are electrically connected to each other by an electric wire (not shown).

  In FIG. 8, a cross section of the second conductive plate 222 is drawn. The cross-sectional shape of the second conductive plate 222 is substantially rectangular, and the second conductive plate 222 is a long thin plate-like conductive member that extends straight in the horizontal direction (the direction perpendicular to the paper surface of FIG. 8). It is a board.

  The cross section of the second conductive plate 222 shown in FIG. 8 shows the width (horizontal direction) and thickness (vertical direction) of the second conductive plate 222. As shown in FIG. 8, it is possible to prevent the flow of air flowing into the plant protection device 10 from being hindered by arranging the second conductive plate 222 so that the width direction thereof is the horizontal direction.

  In FIG. 8, each of these nine second conductive plates 222 is arranged in a horizontal direction (a direction perpendicular to the paper surface of FIG. 8). Each of the nine second conductive plates 222 is arranged so as to be spaced apart from each other so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. As described above, by disposing each of the nine second conductive plates 222 so as to be separated from each other, air can be sufficiently supplied to the plant protection device 10, and the nine second conductive plates 222 can be supplied. Since the shadow produced by each of the conductive plates 222 can be reduced, it is possible to prevent the light irradiated to the plant protection device 10 from being blocked.

  Note that the shape of each of the nine second conductive plates 222 is not limited to a shape that extends straight, and may be any shape that can maintain a constant shape, for example, a constant curve. It may have a curved shape along.

  The nine second conductive plates 222 constituting the second conductor 220 are arranged along the vertical direction (the vertical direction of the paper surface of FIG. 8). That is, the nine second conductive plates 222 are arranged along the second surface 224 substantially parallel to the first surface 214a or 214b described above.

  The second surface 224 can be specified by the same method as the first surfaces 214a and 214b. The second surface 224 is parallel to the first surfaces 214a and 214b described above and is located at a predetermined distance from the first surfaces 214a and 214b. The nine second conductive plates 222 only need to be roughly arranged along the second surface 224, and need not be arranged so as to be included in the second surface 224. That is, it is only necessary that the nine second conductive plates 222 be disposed so as to be visually recognized as if they constitute the second surface 224.

  In the example shown in FIG. 8, the second surface 224 characterizing the entire shape of the nine second conductive plates 222 is a plane, but the second surface 224 is a plane. It is not limited to a certain case, and may be a curved surface. The nine second conductive plates 222 only need to be arranged along a certain surface.

  Similar to the flying organism removing apparatus 100 described above, the first conductors 210 a and 210 b and the second conductor 220 are electrically connected to the power supply 130. In this way, the first conductors 210a and 210b are at the first potential, and the second conductor 220 is at the second potential that is higher than the first potential. In particular, the first conductors 210a and 210b are preferably grounded and have a potential of zero.

  In addition, the distance between the first surface 214a and the second surface 224 and the “one distance” that is the distance between the first surface 214b and the second surface 224 are also the same as the flying organism removing apparatus 100. Similarly, it may be a distance that can cause an accurate discharge to a flying organism, preferably 0.1 to 3 cm, more preferably 0.3 to 2 cm, and further preferably 0.5 to 1 cm. preferable.

  Moreover, it is preferable that there is no dielectric other than air between the first conductors 210 a and 210 b and the second conductor 220. The first conductor 210 and the second conductor 220 may be arranged alternately in the horizontal direction, or only the single first conductor 210 and the single second conductor 220 may be arranged. May be.

  As described above, the dielectric 140 is the same as that of the flying organism removing apparatus 100 and has the same configuration and function, and the arrangement of the eight dielectric plates 142 constituting the dielectric 140 is also the same. It is the same.

  By doing in this way, the electric field (an uneven electric field, a nonuniform field) from which intensity changes with positions can be generated by the dielectric polarization of the eight dielectric plates 142. By generating such an electric field, when a flying creature is charged, the Coulomb force can be exerted on the flying creature, and the flying creature is electrically neutral. In some cases, a gradient force can be exerted by causing electrostatic induction in a flying creature. By generating such an electric field, it is possible to exert a Coulomb force or a gradient force on the flying creature and make it difficult to move the flying creature. By doing so, it is possible to accurately capture flying creatures by the electric field generated by the dielectric polarization of the eight dielectric plates 142.

  Moreover, when each of the eight dielectric plates 142 has a shape having a convex curved surface, as shown by the arrow formed by the curve in FIG. 8, when supplying air to the plant through the flying organism removing device, The convex curved surface can be used to bend the air flow, rotate the air, or generate vortex. By bending the air flow or applying a rotational component to the air flow, the nine first conductive wires 212a, the nine first conductive plates 212b, and the nine second conductive wires described above. It is possible to increase the chance of living creatures that can fly in a region where the electric field generated by the plate 222 and the electric field generated by the dielectric polarization of the eight dielectric plates 142 are present effectively, and can fly accurately. Can be captured or removed. Further, the electric field is effectively increased without increasing the nine first conductive lines 212a, the nine first conductive plates 212b, the nine second conductive plates 222, and the eight dielectric plates 142. Since it is possible to increase the chances of living creatures that can fly in the existing area, the device can be made thinner or smaller.

  Further, as shown in FIG. 8, the first conductive plates 212b and the second conductive plates 222 described above are alternately arranged along the vertical direction (the vertical direction of the paper in FIG. 8). Further, these conductive plates are arranged horizontally. For this reason, the first conductive plate 212b and the second conductive plate 222 are arranged in parallel, but not all face each other, but only partially face each other. By arranging in this manner, the nine first conductive plates 212b and the nine second conductive plates 222 can easily generate an unequal electric field or a non-uniform field. By doing this, it is possible to make the Coulomb force and the gradient force exert on the flying creature, making it difficult to move the flying creature, increasing the chances of causing discharge, and flying. The movable organism can be accurately removed.

  In the above-described flying organism removing apparatus 400, the first conductor is composed of two sets of nine first conductive wires 212a and nine first conductive plates 212b. But you can. What is necessary is just to adjust according to the kind of flying organism to remove, the kind of plant to protect, etc. In addition, the second conductor is only one set of nine second conductive plates 222, but this is also more than two sets depending on the type of flying organisms to be removed, the type of plants to be protected, etc. It may be. Furthermore, in the flying organism removing apparatus 400, only one set of eight dielectric plates 142 is used as the dielectric, but this also depends on the type of flying organism to be removed, the type of plant to be protected, and the like. It may be more than a set.

  FIG. 9A is a cross-sectional view showing the dielectric coated conductor 500. As shown in FIG. 9A, the dielectric covered conductor 500 includes a conductive wire 312 and a dielectric 340.

  The conductive wire 312 shown in FIG. 9A is the same as the first conductor 112a or 112b described above, has a substantially linear shape, and has a horizontal direction (a direction perpendicular to the paper surface of FIG. 9). ) Is a long conductive wire extending straight. A cylindrical dielectric 340 is disposed around the conductive line 312. The dielectric 340 has a long cylindrical shape that extends straight in the horizontal direction. The length of the conductive wire 312 in the longitudinal direction and the length of the dielectric 340 in the longitudinal direction are formed to be substantially the same. In particular, the dielectric 340 is preferably a cylindrical dielectric sheet having a mesh-like dielectric property. Thus, by using a mesh-like sheet, a sufficient amount of air can be supplied to the plant protection device 10 without hindering air flow. By doing in this way, the whole conductor wire 312 can be covered with the dielectric material 340, and it becomes the linear dielectric covering conductor 500.

  In the cross-sectional view shown in FIG. 9A, the gap between the conductive wire 312 and the dielectric 340 is shown. However, the conductive wire 312 may be in close contact.

  Further, a plurality of grooves 244 shown in FIG. 5a or a plurality of recesses 344 shown in FIG. 5b may be formed on the surface of the dielectric 340 of the dielectric coated conductor 500. By doing this, the flow of air can be bent, the air can be rotated, and vortexes can be generated, so the chance of flying creatures in the area where the electric field exists effectively increases. be able to. In addition, by doing this, it is possible to generate an electric field whose electric field strength varies depending on the position, and exerts a Coulomb force or a gradient force on the flying creature and makes it difficult to move the flying creature. Thus, it can be easily captured.

The dielectric 440 has a semi-cylindrical shape obtained by cutting a cylinder into approximately half along the longitudinal direction. A dielectric 440 formed in a semi-cylindrical shape is disposed so as to be in close contact with substantially half of the periphery of the conductive wire 412. In this way, a part of the conductive wire 412 can be covered with the dielectric 440, and the linear dielectric covered conductor 550 is obtained.

  The dielectric coated conductor 550 shown in FIG. 9B may also be formed by forming the plurality of grooves 244 shown in FIG. 5a on the surface of the dielectric 440 or the plurality of recesses 344 shown in FIG. 5b. Good. By doing this, the flow of air can be bent, the air can be rotated, and vortexes can be generated, so the chance of flying creatures in the area where the electric field exists effectively increases. be able to. In addition, by doing this, it is possible to generate an electric field whose electric field strength varies depending on the position, and exerts a Coulomb force or a gradient force on the flying creature and makes it difficult to move the flying creature. Thus, it can be easily captured.

  As shown in FIGS. 9A and 9B described above, by forming the conductive wire and the dielectric integrally, the dielectric is also attached only by attaching the conductive wire to the housing 150. The handling of the removing device can be facilitated.

The end portions of the dielectric covered conductor 510 and the second conductor 120 are supported by the casing 150. The second conductor 120 and the power source 130 have the same configuration as that of the flying organism removing apparatus 100 and have the same function, and thus the description thereof is omitted.

<Dielectric coated conductor 510>
The dielectric coated conductor 510 of the flying organism removing apparatus 600 shown in FIG. 10 has two sets of an outer one (the left side in the drawing) and an inner one (the right side in the drawing). Hereinafter, the outer one is referred to as a dielectric coated conductor 510a, and the inner one is referred to as a dielectric coated conductor 510b.

Each of the nine dielectric-coated conductive wires 512b is also arranged so as to be separated from each other, so that the interval between adjacent ones has a predetermined length, and is substantially parallel to each other. As described above, each of the nine dielectric-coated conductive wires 512a and 512b is arranged so as to be spaced apart from each other, so that air can be sufficiently supplied to the plant protection device 10, and the nine dielectric coatings can be supplied. Since the shadow caused by the conductive lines 512a and 512b can be reduced, it is possible to prevent the light irradiated to the plant protection device 10 from being blocked.

There are two sets of dielectric coated conductors 560 of the flying organism removing apparatus 700 shown in FIG. 11, an outer one (the left side in the drawing) and an inner one (the right side in the drawing). Hereinafter, the outer one is referred to as a dielectric coated conductor 560a, and the inner one is referred to as a dielectric coated conductor 560b. The dielectric covered conductor 560a includes nine dielectric covered conductive wires 562a. The dielectric covered conductor 560b includes nine dielectric covered conductive lines 562b. The broken lines shown in FIG. 11 are a fourth surface 564a that characterizes the overall shape of the nine dielectric-coated conductive wires 562a and a fourth surface 564b that characterizes the overall shape of the nine dielectric-coated conductive wires 562b. This is a virtual surface, not a real surface. The fourth surfaces 564a and 564b may be specified in the same manner as the first surface, the second surface, and the third surface described above. The conductive wires of these nine dielectric coated conductive wires 562a (corresponding to reference numeral 412 in FIG. 9B) and the conductive wires of nine dielectric covered conductive wires 562b (corresponding to reference numeral 412 in FIG. 9B). ) Are side portions 162a or 162b of the housing 150, and are electrically connected to each other by an electric wire (not shown).

  In FIG. 11, a cross section of nine dielectric coated conductive lines 562a and 562b is depicted. Each of the nine dielectric-coated conductive lines 562a and each of the nine dielectric-coated conductive lines 562b has a substantially linear shape and is straight in the horizontal direction (the direction perpendicular to the paper surface of FIG. 11). It has a long shape extending in the direction.

  Each of these nine dielectric coated conductive lines 562a is arranged in the horizontal direction (direction perpendicular to the paper surface of FIG. 11). Each of the nine dielectric-coated conductive wires 562a is spaced apart from each other and arranged so that the distance between adjacent ones is a predetermined length and is substantially parallel to each other. Similarly, each of the nine dielectric-coated conductive lines 562b is arranged in the horizontal direction (direction perpendicular to the paper surface of FIG. 11). Each of the nine dielectric-coated conductive wires 562b is also arranged so as to be separated from each other so that the interval between adjacent ones has a predetermined length and is substantially parallel to each other. As described above, each of the nine dielectric-coated conductive wires 562a and 562b is arranged so as to be spaced apart from each other, so that air can be sufficiently supplied to the plant protection device 10, and the nine dielectric coatings can be supplied. Since the shadow caused by the conductive lines 562a and 562b can be reduced, it is possible to prevent the light applied to the plant protection apparatus 10 from being blocked.

  The shape of each of the nine dielectric-coated conductive wires 562a and the shape of each of the nine dielectric-coated conductive wires 562b are not limited to being linear, and can maintain a certain shape. For example, it may have a curved shape along a certain curve.

  The nine dielectric-coated conductive lines 562a are arranged along the vertical direction (the vertical direction on the paper surface of FIG. 11). That is, the nine dielectric covered conductive wires 562a are arranged along the fourth surface 564a. Nine dielectric-coated conductive wires 562b are also arranged along the vertical direction (the vertical direction on the paper surface of FIG. 11). That is, the nine dielectric covered conductive wires 562a are arranged along the fourth surface 564b.

  Further, as described above, the dielectric covered conductor 560 includes the semi-cylindrical dielectric 440. The dielectric 440 is disposed so as to face the housing opening of the housing 150. Specifically, the dielectrics 440 of the nine dielectric-coated conductive wires 562a are arranged to face the front surface 168a (housing opening) of the housing 150, and the dielectrics 440 of the nine dielectric-coated conductive wires 562b are The housing 150 is disposed so as to face the back surface 168b (housing opening). By doing in this way, since a conductive wire is not arrange | positioned at the housing | casing opening side, even when it is a case where the power supply is supplied to a conductive wire, it can handle safely.

  Moreover, the flying organism removing apparatus 600 described above includes nine dielectric-coated conductive wires 512 a and 512 b and nine conductive wires 122. The flying creature removing apparatus 700 includes nine dielectric-coated conductive wires 562a and 562b and nine conductive wires 122. In this way, it is preferable that at least one set is a conductive wire, that is, a bare wire, rather than all the dielectric covered conductive wires. By doing so, first, from the front surface 168a of the housing 150 toward the back surface 168b, the flying organisms are to be captured by the electric field generated by the dielectric polarization of the nine dielectric-coated conductive wires 512a and 562a. When it cannot be captured by this, an electric field by nine conductive lines 122 can cause discharge to the flying organism. Furthermore, even when flying organisms cannot be removed by this discharge, flying organisms can be captured by the electric field due to the dielectric polarization of the nine dielectric-coated conductive wires 512b and 562b. By comprising in this way, a flying organism can be removed accurately or supplemented.
