This application claims priority based on Japanese Patent Application No. 2018-027744, and is incorporated herein by reference.

The present invention relates to a bird damage countermeasure device that can be installed in a building or the like to suppress the arrival of birds to the building or the like.

The applicant of the present application has conventionally proposed a bird damage countermeasure apparatus described in Patent Document 1. A conventional bird damage countermeasure apparatus has a cross-sectional shape as shown in FIG. 5, for example, and is installed on the roof of a building. Two flat electric shock wires 102 are embedded in the resin base 101, and a direct current is passed through one electric shock wire 102 and the other electric shock wire 102. At this time, when the polarity of one of the electric shock wires 102 is −, the polarity of the other electric wire 102 is +. When birds fly and place their legs so as to straddle one of the lightning lines 102 and the other of the lightning lines 102, the current from the lightning lines 102 flows through the body of the bird. As a result, birds can feel pain and fly away.

Japanese Unexamined Patent Publication No. 2013-247863

However, in the conventional bird damage countermeasure device, although the birds do not straddle between the electric shock lines 102, energization occurs between the electric shock lines 102 and a voltage drop occurs, and thus the birds have come. Even in this case, there was a phenomenon that birds could not be given effective blitz. In particular, this phenomenon tended to become more prominent with the passage of time after installation.

The present invention was conceived by the inventor who faced the above phenomenon after earnest research, and its task is to suppress unintentional energization between the electric shock wires for a long period after installation and maintain performance. It is to provide a bird damage countermeasure device that can be used.

The present invention is a rigid rod-like body formed of a nonconductor and formed of an elongated shape and a conductor, and is embedded in the base portion so that a part thereof is exposed upward, and the elongated shape A bird damage countermeasure apparatus comprising: a plurality of lightning sections extending in a longitudinal direction and having a cross-sectional contour shape orthogonal to the longitudinal direction and having a curved shape without corners.

Further, the contour shape of the cross section perpendicular to the longitudinal direction of each of the plurality of lightning portions may be a perfect circle shape.

Further, the upper surface of the base portion may be inclined so that the other end side is lower than the one end side in the width direction orthogonal to the longitudinal direction.

In addition, as the upper surface of the base portion moves from one end side to the other end side in the width direction, the base portion may be gradually inclined and then steeply inclined between the electric shock portions adjacent in the width direction. .

In addition, each of the plurality of installation units is configured to have a predetermined length by combining the base portion and the plurality of lightning portions, and each of the plurality of installation units adjacent in the longitudinal direction. The installation units can be configured to be connected to each other by a joint member that can be fitted from the outside to the electric shock sections having the same polarity.

Moreover, in each of the plurality of installation units having the predetermined length, each of the plurality of lightning portions can be longer than the base portion.

FIG. 2A is a plan view showing an installation example of the installation unit. FIG. 2B is a side view showing a connection portion between the installation units.

It is a longitudinal cross-sectional view which shows the shape of the installation unit in the conventional bird damage countermeasure apparatus.

Next, the present invention will be described by taking one embodiment. As shown in FIG. 1, the bird damage countermeasure apparatus 1 according to this embodiment includes an installation unit 2 installed on an installation target such as a building (for example, the upper surface of the parapet P or the upper surface of the headboard covered with the parapet P). And a power supply unit 3 (only schematically shown) for supplying power to the installation unit 2. The power supply unit 3 has the same configuration as that conventionally used, and therefore will not be described in detail. Regarding the power supply unit 3, it is assumed that a solar cell is provided, and the power generated by sunlight is boosted and supplied to the installation unit 2. This configuration is preferable because it does not require connection to a commercial power source, and electrical work can be omitted.

As shown in FIGS. 2A, 2B, and 3, the installation unit 2 is configured by combining a base portion 4 and a plurality (two in this embodiment) of electric shocks 5. A high-voltage direct current flows from the power supply unit 3 to the electric shock unit 5. The output voltage of the power supply unit 3 of this embodiment is set to 8000 V in a no-load state. At least one of the plurality of electric shocks 5 is connected to the negative pole of the power supply unit 3, and at least one other is connected to the positive pole of the power supply unit 3. In the present embodiment, each of the electric shocks 5 is connected to the negative pole and the positive pole of the power feeding unit 3. The electric poles 5 having different polarities are connected to each other at the end opposite to the power supply unit 3 to form a closed circuit.

The base part 4 has a flat shape with a small height dimension with respect to the width dimension, and has an elongated shape. The base portion 4 is entirely formed of a nonconductor. The base portion 4 of the present embodiment is formed by extrusion molding of a soft vinyl chloride resin (PVC) (but is not limited to this. The material may be other plastic, rubber, or elastomer). As will be described later, a relatively hard material can be used for the base portion 4 in response to using a hard rod-like body as the electric shock portion 5. Since a hard material can be used, for example, even if a bird is pecking with a beak or hooking a nail, the base portion 4 is not easily damaged. For this reason, it can prevent that the electric shock part 5 remove | deviates from the base part 4 by damage of the base part 4. FIG. In addition, it is not essential that the whole base part 4 is a nonconductor, and the area | region which touches the outer periphery of each electric shock part 5 should just be formed with the nonconductor.

Regarding the hardness of the base part 4, if the hardness is too small, it becomes difficult to fix the electric shock part 5 to the base part 4, and the electric shock part 5 is liable to be displaced or detached. In particular, when the electric shock part 5 is extended due to the influence of the ambient temperature, the electric shock part 5 is easily detached from the base part 4. Moreover, when the installation surface of the base part 4 has an unevenness | corrugation, it is easy to deform | transform so that it may wave by distorting by thermal expansion and contraction. If this deformation becomes severe, the electric shock section 5 may come off from the base section 4, and an unintended discharge or short circuit may occur. On the other hand, if the hardness is too high, it is difficult to fit the electric shock part 5 to the base part 4 and it becomes difficult to construct. Moreover, if it tries to fit forcefully, the electric shock part 5 will be distorted. For this reason, the hardness of the base portion 4 is preferably from 30 to 70 HDD, more preferably from 40 to 60 HDD in terms of durometer hardness (JIS K 7215).

The base part 4 is formed in a predetermined longitudinal dimension. By connecting the plurality of base portions 4 in the longitudinal direction of the elongated shape, flexible installation according to the installation location is possible. Small irregularities are formed on the bottom surface 41 of the base portion 4. In the present embodiment, a large number of small grooves along the longitudinal direction are provided. This functions as a slipper against the installation surface.

A plurality of fitting grooves 42 are formed on the upper surface of the base portion 4. Each fitting groove 42 is formed to be continuous from one end to the other end in the longitudinal direction of the base portion 4. In the present embodiment, two fitting grooves 42 are formed in parallel according to the number of lightning portions 5. Each fitting groove 42 has a circular cross-sectional shape corresponding to the cross-sectional shape of the electric shock portion 5, and an upper portion is open to the upper surface of the base portion 4. As shown in FIG. 3, the electric shock part 5 is embedded by being fitted into the fitting groove 42 so that a part thereof is exposed upward in the base part 4. The electric shock section 5 is continuously embedded from one end to the other end in the longitudinal direction of the base section 4 while being wrapped in the fitting groove 42. In addition, in order to connect the installation unit 2 adjacent to a longitudinal direction, the longitudinal dimension of the electric shock part 5 is large compared with the longitudinal dimension of the base part 4, as shown to FIG. For this reason, the electric shock portion 5 embedded in the fitting groove 42 protrudes from the longitudinal end portion of the base portion 4. The interval between the adjacent fitting grooves 42 is set to an interval at which the leg portions of the type of bird assumed as a countermeasure target can naturally span between the adjacent electric shock portions 5 in a state where the electric shock portions 5 are embedded. Is done. As shown in the drawing, the electric shock portion 5 is exposed upward from a state in which the electric shock portion 5 protrudes from the upper surface of the base portion 4 (a part of the electric shock portion 5 is the upper end in the cross-sectional shape of the base portion 4 (the fitting groove 42). The state of being located above the upper end) is preferable because it easily touches the legs of birds. However, it may be in a state where it is exposed but not protruding, such as being exposed so that a part of the electric shock portion 5 is exposed on the back side of the fitting groove 42. In order to support the electric shock part 5 reliably, the upper part of the fitting groove 42 protrudes so that a part of space where the electric shock part 5 is arrange | positioned may be covered from upper direction. In this configuration, the electric shock part 5 can be reliably retained in the space by the elasticity of the base part 4 made of resin.

The upper surface 43 of the base portion 4 is in the direction of the arrow 43S shown in FIG. 3, and is located on the other end side (left side in FIG. 3) rather than one end side (right side in FIG. 3) in the width direction orthogonal to the longitudinal direction. Are formed along a slope (single slope) that gradually decreases. The term “along” is not limited to the one parallel to the one-side inclined line (linear line), and includes one that repeats rising and lowering across the one-side inclined line. In short, the upper surface 43 may be shaped so that the other end side is lower than the one end side in the width direction. The upper surface 43 of the present embodiment has a shape that is suddenly raised from the bottom surface 41 and draws a round shape at one end side in the width direction. Then, it descends along the direction of the arrow 43S, and at the other end side in the width direction, it is shaped so as to gently descend and reach the bottom surface 41.

By forming the upper surface 43 of the base portion 4 in this way, the installation unit 2 is used outdoors. Therefore, when installing at the upper end portion of a building in particular, rainwater can be concentrated on the upper surface 43 of the base portion 4. Since it can flow in the direction, drainage is good. When installing the installation unit 2 on the upper surface of the parapet P as shown in FIG. 1, the lower end portion of the base portion 4 is installed on the side close to the edge of the upper surface of the parapet P, so that the base portion 4 can be quickly dropped from the upper surface of the parapet P.

In particular, in the present embodiment, as the upper surface 43 of the base portion 4 moves from one end side in the width direction to the other end side, it is once gently inclined between the electric shock portions 5 adjacent in the width direction (intermediate upper surface 431). It is a wavy shape that becomes steep after becoming. In other words, as shown in FIG. 3, the upper surface 43 slightly descends to the left side of the drawing from the higher side electric shock 5 and rises after becoming one end side recess 431a, and gently rises upward. After passing through the intermediate convex portion 431b which is a convex portion protruding to the lower end, it descends again, continues to the other end side concave portion 431c which is a gentle concave portion, and then reaches the right side of the low-side electric shock portion 5 Shape. By adopting such a shape, even if rainwater accumulates in the region between the lightning portions 5 (intermediate upper surface 431) in the upper surface 43 of the base portion 4, the other end side concave portion 431c having a relatively large space, Or it will be divided and collected in the one end side crevice 431a which has a comparatively small space. Moreover, since the intermediate convex part 431b protrudes compared with the one end side recessed part 431a and the other end side recessed part 431c, rainwater does not accumulate over the whole area of the intermediate upper surface 431. Therefore, it is possible to suppress rainwater from remaining on the intermediate upper surface 431 in a state in which the adjacent electric shocks 5 are accumulated and are conducted through water. In order to allow birds to place their legs so as to straddle adjacent electric shocks 5, it is desirable that the intermediate protrusion 431 b not be too high. Specifically, it is desirable that the intermediate convex portion 431b is formed so as not to exceed the tangent line with reference to the tangent line of the portion exposed from the base portion 4 between the adjacent lightning portions 5.

The electric shock section 5 is a hard rod-shaped body made of a conductor and has an elongated shape. Specifically, the electric shock section 5 is made of metal, and in the present embodiment, is made of a stainless alloy (but is not limited to this). Since the stainless alloy is not easily corroded, it is suitable for use in the installation unit 2 installed outdoors. Here, the term “hard” means that the electric shock section 5 is independent and has a length used for the installation unit 2, so that it does not (almost) bend even if the longitudinal direction is directed vertically. It is a property having properties. The rod-shaped body constituting the electric shock section 5 is set to have rigidity and dimensions so as to have the self-supporting property. Therefore, the rod-shaped body that constitutes the electric shock section 5 of the present embodiment is different from a flexible linear body, such as a linear body that has been stripped from an electric wire that is used exclusively for the flow of electricity. It is an object. The electric shock portion 5 has a curved shape in which the contour shape (outer edge shape) of the cross section orthogonal to the longitudinal direction is free from corners. Here, the “corner” is not limited to a corner formed by intersecting two straight lines in the cross-sectional contour shape, and includes a curved shape. Specifically, a “pointed” shape (a shape like the electric shock line 102 shown in FIG. 5) due to the curvature of the curvature being significantly larger than other curved portions is also included. In the electric shock section 5 of the present embodiment, since there is no corner that can be the starting point of discharge, electric discharge between the electric shock sections 5 is unlikely to occur. Here, in particular, in the conventional bird damage countermeasure device, the electric shock wire is exposed in the air at the connection point between the electric shock wires, and the discharge from the corner portion of the electric shock wire is concentrated in this exposed portion. There was a suspicion. On the other hand, since the electric shock section 5 of the present embodiment has a curved shape with no corners, it is difficult to generate a discharge that has been suspected in the past even at the connection portion between the electric shock sections 5. Therefore, unintended energization between the electric shock sections 5 can be suppressed over a long period after installation, and the performance of the bird damage countermeasure apparatus 1 can be maintained. In this embodiment, the contour shape of the cross section orthogonal to the longitudinal direction of the electric shock part 5 is a perfect circle shape. For this reason, since the metal round bar which is marketed generally and can be obtained easily can be utilized as the electric shock part 5, it can contribute to manufacturing cost reduction, for example. In this embodiment, a round bar having a diameter of 4 mm is used. However, when using a round bar, the diameter of the electric shock part 5 is not restricted to this, and can be various diameters. The “perfect circle shape” is not limited to a geometrically perfect circle, and includes a contour shape deviated from the geometrically perfect circle due to a manufacturing error or the like. Also included is a contour shape that is interpreted as a “circle” for social conventions.

Here, in the conventional bird damage countermeasure device, there was one that was configured such that the blitz wire was installed in the air. However, with such a configuration, there is a risk that an operator's foot may be caught during maintenance of a building or the like. Further, there is a risk that the electric shock wire may be deformed or damaged by being pressed by a maintenance tool (for example, a rope hanging by an operator during window cleaning work). On the other hand, the electric shock part 5 of this embodiment is embedded in the flat base part 4. FIG. Moreover, the base portion 4 is made of a softer material than the electric shock portion 5. For this reason, the said inconvenience does not occur easily compared with the structure in which the electric shock wire is installed in the air. Moreover, since the upper surface 43 of the base part 4 is made into the shape which changes gently in the width direction as mentioned above, even if it is installed in a building, it is hard to be caught on an operator's leg, and the base part 4 is from a building. Another advantage is that inconveniences such as peeling off hardly occur.

Further, by using a hard rod-like body as the electric shock section 5, even if a relatively hard material is used for the base section 4, an operator can easily fit the electric shock section 5 into the fitting groove 42. . Moreover, since the electric shock part 5 does not bend easily according to the temperature of an installation place, all of the electric shock parts 5 are removed from the base part 4 due to the influence of the air temperature, or fall off or partially covered with the parapet P. It is possible to prevent electric discharge from being generated with respect to the cap board (in particular, when it is made of metal). In particular, since the installation unit 2 of the present embodiment is installed at a high place, it is a great merit that the damage caused by the electric shock unit 5 can be prevented. Moreover, the electric shock part 5 is not bent by the weight of the bird. Moreover, it is possible to prevent the lightning unit 5 from being damaged by a bird pecking with a beak or hooking a nail. Moreover, since the electric shock part 5 does not bend easily, it can prevent that the bird removes the electric shock part 5 from the fitting groove 42 of the base part 4. FIG. As described above, the electric shock section 5 of the present embodiment has many advantages as compared with the case where a flexible linear body such as one in which the coating is removed from the electric wire to form a bare wire as the electric shock section.

As described above, the base unit 4 and the plurality of lightning units 5 are combined to form the installation unit 2 having a predetermined length. In this embodiment, the length of one installation unit 2 is 2 m. However, the length of the installation unit 2 can be set as appropriate. Further, as shown in FIG. 2A, when arranging the installation units 2 in a right angle direction, the longitudinal edge of the base portion 4 facing the right angle portion may be inclined, and a length difference may be provided in the length of the electric shock portion 5. Is possible.

The plurality of installation units 2 adjacent in the longitudinal direction or the right-angle direction are configured to be connected by joint members 6 that can be fitted from the outside to the electric shocks 5 of the same polarity. In addition, in order to prevent the discharge from the electric shock part 5 to a building etc. under the part where the base part 4 was interrupted including the joint member 6, it is possible to arrange an insulating material such as an insulating sheet. preferable.

The joint member 6 is elastically deformed and fitted into both electric shocks 5 in a manner as shown in FIG. 4A so as to straddle the electric shocks 5 adjacent in the longitudinal direction or the right angle direction. The state before fitting is a state indicated by a two-dot chain line, and the state after fitting is a state indicated by a solid line. The joint member 6 is formed by bending a plate-like body formed of a conductor. The joint member 6 of this embodiment is made of a stainless alloy. Attachment portions 61 are formed at both ends in the longitudinal direction, and connection portions 62 are formed in the middle. By this joint member 6, a plurality of installation units 2 can be easily connected. Therefore, the workability on site at the time of installation is good. Further, by using a hard rod-like body as the electric shock section 5, the portion that protrudes from the end portion in the longitudinal direction of the base section 4 in the electric shock section 5 is not bent and is kept straight. Therefore, the joint member 6 can be easily fitted into the adjacent electric shocks 5.

In the installation unit 2 of the present embodiment, the electric shock section 5 is formed longer than the base section 4. Due to the difference in length between them, the electric shock part 5 protrudes from the base part 4 (because the end part of the electric shock part 5 is not covered by the base part 4), so the work of fitting the joint member 6 into the electric shock part 5 is easy. Can be. Further, as shown in FIGS. 2A and 2B, a gap 2S is generated between the base portions 4, and therefore this gap 2S can be used for draining the upper surface of the parapet P or the like. Therefore, it is possible to avoid rainwater remaining around the base portion 4 (particularly the bottom surface 41) for a long time.

Further, the joint member 6 can be used by bending the connecting portion 62 located in the middle. For this reason, for example, when installing the installation unit 2 in a corner portion of a parapet, the corner portion is attached by attaching a bent joint member 6 between the installation units 2 installed orthogonally as shown in FIG. 2A, for example. The installation unit 2 can be easily connected. The joint member 6 may be bent so as to have a corner as shown in FIG. 2A, or may be bent so as to be curved as shown in FIG. 4B. As shown by a two-dot chain line in FIG. 4B, the direction in which the connecting portion 62 is bent or bent can be set as appropriate.

Next, the inventor conducted a test of energization by installing the bird damage countermeasure apparatus 1 of the present embodiment and the conventional bird damage countermeasure apparatus shown in FIG. The old and new bird damage control equipment installation units were installed for 40 meters outdoors. During a clear daytime, the same power supply unit was connected to each installation unit of the new and old bird damage countermeasure devices, and the voltage (potential difference) generated between the lightning sections was measured.

In the bird damage countermeasure apparatus 1 of the present embodiment, the voltage was 7600 V at any of the energization distances 0 m, 15 m, and 40 m, and the measured value was stable. On the other hand, in the conventional bird damage countermeasure device, the voltage at the energization distance of 0 m was 7600 V, the voltage at the same 15 m was 7500 V, the voltage at the same 40 m was 7200 V, and the voltage decreased as the energization distance became longer. . Moreover, the measured value moved up and down and was not stable. From this test result, it was actually confirmed that the bird damage countermeasure apparatus 1 of the present embodiment is superior with no voltage drop as compared with the prior art.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

For example, although the base part 4 and the electric shock part 5 of the said embodiment were the shapes extended linearly, it can also be made into the curved shape. Moreover, although the base part 4 and the electric shock part 5 are linear, for example, a slit is formed in the base part 4, and a flexible linear body (the electric shock part 5 of the embodiment described above is configured as a reference example). By using a different material from a hard rod-like body to be made, a flexible structure that can be easily bent on site can be obtained.

Moreover, in the said embodiment, although the outline shape of the cross section orthogonal to the longitudinal direction of the electric shock part 5 was a perfect circle shape, various shapes, such as an ellipse, an ellipse, and the shape (glasses shape) in which two or more circles were continued. It can be. However, even if the contour shape (outer edge shape) of the cross section orthogonal to the longitudinal direction of the electric shock section 5 is a curved shape without corners, if the shape is too flat, it is possible to discharge from the flat tip portion. There is sex. For this reason, as for the cross-sectional shape of the electric shock part 5, it is preferable to make flatness into 0 or more and 0.7 or less, and it is more preferable to set it as 0 or more and 0.5 or less.

Further, the joint member 6 is not limited to that of the above-described embodiment, and may be formed in a shape like a coil spring, for example, and arranged on the outer periphery of the electric shock portion 5. In addition, the joint member 6 can take various forms as long as it is a conductor that can be fixed to the electric shock section 5.

The configuration and operation related to the embodiment will be described collectively below. The embodiment is a non-conductor, elongated base portion 4 and a hard rod-like body formed of a conductor, embedded in the base portion 4 so that a part thereof is exposed upward, The bird damage countermeasure apparatus 1 includes a plurality of electric shocks 5 extending in a longitudinal direction in the elongated shape and having a curved shape with a corner having a curved cross section perpendicular to the longitudinal direction.

According to this configuration, the cross-sectional contour shape of each of the plurality of electric shocks 5 is a curved shape with no corners. For this reason, it is hard to produce the discharge between the adjacent electric shock parts 5. FIG.

Further, the contour shape of the cross section perpendicular to the longitudinal direction of each of the plurality of electric shocks 5 can be a perfect circle.

According to this configuration, for example, a commercially available metal round bar can be used as the electric shock section 5, which can contribute to a reduction in manufacturing cost.

Further, the upper surface 43 of the base portion 4 can be inclined so that the other end side is lower than the one end side in the width direction orthogonal to the longitudinal direction.

による According to this configuration, when the base part 4 is installed particularly at the upper end of the building, rainwater can flow in one direction, so drainage is good.

Further, as the upper surface 43 of the base portion 4 moves from one end side in the width direction to the other end side, it once becomes a gentle slope between the electric shock portions 5 adjacent in the width direction and then becomes a steep slope. I can do it.

According to this configuration, it is possible to suppress the rainwater from remaining in a state in which the adjacent lightning portions 5 are conductive, particularly in the region 431 between the lightning portions 5 in the upper surface 43 of the base portion 4.

The plurality of installation units 2 are configured to have a predetermined length by combining the base portion 4 and the plurality of lightning portions 5 and are adjacent to each other in the longitudinal direction. The plurality of installation units 2 to be configured can be configured to be connected by joint members 6 that can be fitted from the outside to the electric shocks 5 of the same polarity.

According to this configuration, the plurality of installation units 2 can be easily connected by the joint member 6.

Further, in each of the plurality of installation units 2 having the predetermined length, each of the plurality of lightning portions 5 can be longer than the base portion 4.

According to this configuration, since the electric shock section 5 protrudes from the base section 4 due to the difference in length between the two, the work of fitting the joint member 6 into the electric shock section 5 can be facilitated. Furthermore, since a gap 2S is generated between the base portions 4, the gap 2S can be used for drainage.

As mentioned above, according to the said embodiment, it is hard to produce the discharge between the electric shock parts 5. FIG. For this reason, the unintended electricity supply between the electric shock parts 5 can be suppressed over the long term after installation, and performance can be maintained.
