Description

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

  The applicant of the present application has conventionally proposed a bird damage countermeasure device 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.

JP2013-247863A

  However, in the conventional bird damage countermeasure device, even though the birds do not straddle between the electric shock lines 102, energization occurs between the electric shock lines 102 and a voltage drop occurs, so that the birds fly. 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 includes a base portion formed of a non-conductor and extending in the longitudinal direction, and formed of a conductor, embedded in the base portion so as to be partially exposed upward, extending in the longitudinal direction, and extending in the longitudinal direction. A plurality of electric shock lines having a curved shape with no corners, and the upper surface of the base portion is along an inclination in which the other end side is lower than the one end side in the width direction. One end-side recess that is formed and between which the upper surface descends on the one end side, and the other end-side recess that the upper surface descends on the other end side, between the electric shock lines adjacent in the width direction. And an intermediate convex portion whose upper surface protrudes upward in the middle, and the intermediate convex portion is based on the tangent of the portion exposed from the base portion between the electric shock lines adjacent in the width direction, that is formed so as not to exceed the upward of the tangent It is a harm countermeasure device.

According to this configuration, the cross-sectional contour shape is a curved shape with no corners with respect to each electric shock line. For this reason, it is hard to produce the discharge between electric shock lines. Moreover, especially when installed at the upper end of a building, rainwater can flow in one direction, so drainage is good. Moreover, it can suppress that rainwater remains on the upper surface of a base part in the state which adjacent electric shock lines conduct | electrically_connect through accumulated water. In addition, birds can place their legs so as to straddle adjacent electric shock lines.

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 has a shape that is once gently inclined and then steeply inclined between the electric shock lines adjacent in the width direction. I can do it.

According to this configuration, it is possible to prevent rainwater from remaining in a state where adjacent electric shock wires are conductive, particularly in the region between the electric shock wires, in the upper surface of the base portion .

In addition, the upper surface of the base portion has a shape that is suddenly raised from the bottom surface at one end in the width direction, and gently descends to the bottom surface at the other end in the width direction. It can be assumed that it is a shape to reach .

Also, for each of the plurality of shock lines, it is assumed the contour shape of the cross section perpendicular to the longitudinal direction is a perfect circle shape.

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

  In addition, the base unit and the plurality of electric shock wires are combined to form an installation unit having a predetermined length, and the installation units adjacent in the longitudinal direction are fitted into the electric shock wires of the same polarity from the outside. It can be connected by a joint member that can.

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

  Further, in the installation unit having the predetermined length, each of the plurality of electric shock wires can be longer than the base portion.

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

  According to the present invention, it is difficult to cause a discharge between the electric shock lines. For this reason, it is possible to maintain the performance by suppressing unintentional energization between the electric shock wires for a long period after installation.

It is a longitudinal cross-sectional perspective view which shows the example of installation of the installation unit in the bird damage countermeasure apparatus which concerns on one Embodiment of this invention. (A) is a top view which shows the example of installation of the said installation unit, (B) is a side view which extracts and shows the connection part of the said installation units. It is a longitudinal cross-sectional view which shows the shape of the said installation unit. The joint member used for the said bird damage countermeasure apparatus is shown, (A) is a longitudinal cross-sectional view which shows the attachment condition to an electric shock wire, (B) is a figure which shows an example of the deformation | transformation in the bending arrangement | positioning part of the said installation unit. 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 up 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 FIG. 2 (A), (B) or FIG. 3, the installation unit 2 is configured by combining a base portion 4 and a plurality (two in this embodiment) of electric shock wires 5. A high-voltage direct current flows from the power supply unit 3 to the electric shock wire 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 shock wires 5 is connected to the negative pole of the power supply unit 3, and at least the other one is connected to the positive pole of the power supply unit 3. In the present embodiment, each one of the electric shock wires 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 portion 4 has a flat shape with a small height dimension relative to the width dimension, and has a shape extending in the longitudinal direction. The base portion 4 is entirely formed of a nonconductor. In this embodiment, it is formed by extrusion molding of a soft vinyl chloride resin. In addition, it is not essential that the whole base part 4 is a nonconductor, and at least the outer peripheral area | region of each electric shock wire 5 should just be formed with the nonconductor.

  The base portion 4 is formed with a predetermined longitudinal dimension. By connecting a plurality of base portions 4 in the longitudinal direction, 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. In the present embodiment, two fitting grooves 42 are formed in parallel in accordance with the number of the electric shock wires 5. Each fitting groove 42 has a circular cross-sectional shape corresponding to the cross-sectional shape of the electric shock wire 5, and an upper portion is open to the upper surface of the base portion 4. As shown in FIG. 3, the electric shock wire 5 is embedded by being fitted into the fitting groove 42 so that a part of the base portion 4 is exposed upward. In addition, in order to connect the installation units 2 adjacent in the longitudinal direction, the longitudinal dimension of the electric shock wire 5 is larger than the longitudinal dimension of the base portion 4 as shown in FIG. For this reason, the electric shock wire 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 of the type of bird assumed as a countermeasure target can naturally span between the adjacent electric shock wires 5 in the state where the electric shock wires 5 are embedded. Is done. As shown in the drawing, the exposed state of the electric shock wire 5 is a state in which the electric shock wire 5 protrudes from the upper surface of the base portion 4 (a portion of the electric shock wire 5 is positioned above the upper end in the cross-sectional shape of the base portion 4). Is preferable because it is easy to touch the legs of birds. However, it may be in a state where it is exposed but not protruding, for example, a part of the electric shock wire 5 is exposed to the back of the fitting groove 42. In order to support the electric shock wire 5 reliably, the upper part of the fitting groove 42 protrudes so as to cover a part of the space where the electric wire 5 is arranged from above. In this configuration, the electric wire 5 can be securely held in the space by the elasticity of the base portion 4.

  The upper surface 43 of the base portion 4 is in the direction of the arrow 43S shown in FIG. 3 and has an inclination that is gradually lower on the other end side (left side in FIG. 3) than on one end side (right side in FIG. 3) in the width direction ( It is formed along one slope). 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, the upper surface 43 of the base portion 4 is once gently inclined between the electric shock lines adjacent to each other in the width direction (intermediate upper surface 431) as it goes from one end side to the other end side in the width direction. It has a wavy shape with a steep slope. Specifically, as shown in FIG. 3, the upper surface 43 slightly descends to the left of the higher side of the electric shock wire 5 and rises after forming one end side recess 431a, and gently protrudes upward. After passing through the intermediate convex part 431b which is a convex part, it descends again, continues to the other end side concave part 431c which is a gentle concave part, and then reaches the right side of the low-side electric shock wire 5 . By adopting such a shape, even if rainwater accumulates in the region between the electric shock lines 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 prevent rainwater from remaining in a state in which adjacent electric shock wires 5 are electrically connected to each other through accumulated water. In addition, in order to allow birds to place their legs so as to straddle the adjacent electric shock lines 5, specifically, the base part is not provided between the adjacent electric shock lines 5 so that the intermediate convex part 431 b does not become too high. It is desirable to form so as not to exceed the tangent line with reference to the tangent line of the portion exposed from 4.

  The electric shock wire 5 is a rod-shaped body formed of a conductor and has a shape extending in the longitudinal direction. In this embodiment, it is made of a stainless alloy. Since it does not corrode easily, it is suitable for use in the installation unit 2 installed outdoors. The electric shock wire 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 wire 5 of this embodiment, since there is no corner that can be a starting point of discharge, electric discharge between the electric shock wires 5 hardly occurs. 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 wire 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 point between the electric shock wires 5. Therefore, unintended energization between the electric shock wires 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 outline shape of the cross section orthogonal to the longitudinal direction of the electric shock wire 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 wire 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 a round bar is used, the diameter of the electric shock wire 5 is not limited to this, and can be various diameters.

  Here, in the conventional bird damage countermeasure apparatus, there existed what was comprised so that a blitz could be 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 wire 5 of the present embodiment is embedded in the flat base portion 4. Moreover, the base portion 4 is made of a soft material. 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.

  As described above, the base unit 4 and the plurality of electric shock wires 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 the installation units 2 are arranged in a right angle direction, the longitudinal edge of the base portion 4 facing the right angle portion is slanted, and the length difference of the electric shock wire 5 is increased or decreased. It is also possible to provide it.

  The installation units 2 adjacent to each other in the longitudinal direction are connected by joint members 6 that can be fitted from the outside to the electric shock wires 5 having the same polarity. In addition, in order to prevent the discharge from the electric shock wire 5 to the building or the like below the portion including the joint member 6 where the base portion 4 is interrupted, an insulating material such as an insulating sheet may be disposed. preferable.

  The joint member 6 is elastically deformed and fitted into both the electric shock wires 5 in a manner as shown in FIG. 4A so as to straddle the electric shock wires 5 adjacent in the longitudinal 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. In this embodiment, it 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.

  In the installation unit 2 of this embodiment, the electric shock wire 5 is formed longer than the base portion 4. Due to the difference in length between the two, since the electric shock wire 5 protrudes from the base portion 4 (because the end portion of the electric shock wire 5 is not covered by the base portion 4), the work of fitting the joint member 6 into the electric shock wire 5 is easy. Can be. Further, as shown in FIGS. 2 (A) and 2 (B), a gap 2S is generated between the base portions 4, so that the 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 the corner portion of the parapet, for example, as shown in FIG. 2A, by attaching the bent joint member 6 between the installation units 2 installed orthogonally The installation unit 2 at the corner can be easily connected. The joint member 6 may be bent so as to have a corner as shown in FIG. 2 (A), or may be bent so as to be curved as shown in FIG. 4 (B). 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, a description will be given of 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 electric shock lines 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.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the summary of this invention.

  For example, although the base part 4 and the electric shock wire 5 of the said embodiment were the shapes extended linearly, they can also be made into the curved shape. Moreover, although the base part 4 and the electric shock wire 5 are linear, for example, by forming a slit in the base part 4 and using a flexible linear body for the electric shock wire 5, it can be easily bent at the site. It can also be set as a flexible structure.

  Moreover, in the said embodiment, although the outline shape of the cross section orthogonal to the longitudinal direction of the electric shock wire 5 was a perfect circle shape, it is various shapes, such as an ellipse, an ellipse, and the shape (glasses shape) in which multiple circles 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 wire 5 is a curved shape without corners, if the shape is too flat, the discharge may occur from the flat tip portion. There is sex. For this reason, as for the cross-sectional shape of the electric shock wire 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 wire 5. In addition, the joint member 6 can have various forms as long as it is a conductor that can be fixed to the electric shock wire 5.
