Description

Technical Field

[0001] The present invention relates to a bird damage prevention tool that has a high bird damage prevention effect and excellent portability when carried to high places such as electric wires.

Background Art

[0002] Electricity generated at a power plant is sent to each household via transmission lines and distribution lines. However, the electric wires are laid out in various places, and in some places, birds perch on the wires, causing problems such as wire deterioration due to bird droppings, deterioration of the surrounding environment, and power outages due to birds getting electrocuted.

[0003] To solve these problems, various methods have been considered. As one of them, a core wire (corresponding to a winding wire in Patent Document 1) with ring bodies arranged at required intervals is wound around an electric wire, and the ring bodies arranged on the outside act as an obstruction to prevent birds from approaching or perching on the wire (Patent Document 1). This bird damage prevention tool is planar.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In order to reduce the blank space where birds can enter, the bird damage prevention tool preferably has a three-dimensional shape. However, when it is made three-dimensional, its portability when carried to high places such as electric wires decreases. The object of the present invention is to provide a bird damage prevention tool that has a three-dimensional shape during use, such as when wound around an electric wire, and high portability.

Means for Solving the Problems

[0006] As a result of various studies to achieve the above objective, the inventors have discovered a mechanism that allows the bird-repellent devices to be made three-dimensional by simply bringing adjacent bird-repellent devices closer together when in use, while remaining flat when transported, and thus arrived at the present invention. That is, the present invention is as follows. 1. A bird damage prevention device comprising a core wire to which multiple bird damage prevention bodies are attached, The bird damage prevention device consists of a bird damage prevention device fixed to a core wire and a bird damage prevention device that is movable along the core wire, and the bird damage prevention device is equipped with a guide that rotates one bird damage prevention device relative to the other bird damage prevention device by bringing adjacent bird damage prevention devices closer together. A bird damage prevention device that, using the guide, can rotate and erect the bird damage prevention body, thereby creating a three-dimensional bird damage prevention device from a flat plate. 2. A bird damage prevention body, which is movable along the core wire and includes a pull wire running parallel to and close to the core wire, is fixed to the pull wire. The bird damage prevention device according to the first invention, wherein by shifting the core wire and the pull wire in opposite directions, a bird damage prevention body fixed to the core wire and a bird damage prevention body movable along the core wire can be brought closer together. 3. The bird damage prevention device described in item 2 above, wherein part or all of the bird damage prevention body is frame-shaped. 4. The bird damage prevention device described in item 3 above, wherein a part of the bird damage prevention device also serves as a guide. 5. A bird repellent device according to any one of 1, 2, 3, or 4 above, which has a stopper to prevent both bird repellent devices that have approached each other from returning to their original positions. [Effects of the Invention]

[0007] The bird-repellent device of this invention has a three-dimensional shape when in use, resulting in a high level of bird-repellent effect. When transported, it is flat, making it highly portable, meaning that many can be carried at once to high places such as power lines. [Brief explanation of the drawing]

[0008] [Figure 1] An example of a bird damage prevention device of the present invention is shown. [Figure 2] This image shows the bird damage prevention device of the present invention in an upright position. [Figure 3] This shows how the bird damage prevention device of the present invention looks when wrapped around a linear body. [Figure 4] This shows how the bird-repellent device stands upright. The ring-shaped bird-repellent device 4 moves in the direction of the arrow relative to the ring-shaped bird-repellent device 3, and the ring-shaped bird-repellent device 4 stands upright in the sequence (A)⇒(B)⇒(C). [Figure 5] Figure 4 shows the same view from a different direction. [Figure 6] This image shows a close-up of the stopper portion that prevents the bird deterrent from returning to its original position and flattening as the bird deterrent approaches. [Modes for carrying out the invention]

[0009] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.

[0010] 1. Regarding the structure of the bird damage prevention device 21 of the present invention The bird damage prevention device 21 of the present invention (Figure 1) is a bird damage prevention device that becomes three-dimensional by the rotation and uprighting of the bird damage prevention bodies (3, 4) (Figure 2). By wrapping the core wire 1 to which the bird damage prevention bodies are attached around a linear body 5 such as an electric wire (Figure 3), it prevents birds from approaching or perching on the linear body 5, thereby preventing bird damage. The bird-repellent devices 3 and 4 (Figure 1) are not particularly restricted in shape as long as they are designed to make it difficult for birds to perch on them. For example, they may be made of a flexible material in the shape of a frame, such as a ring (hereinafter sometimes referred to as frame or ring), or they may be shaped like protrusions. If they are frame-shaped, they can prevent birds from approaching, and if a bird tries to perch on them, the frame will bend under the weight of the bird, thus preventing it from perching. If they are shaped like protrusions, they will be deterred, preventing birds from approaching or perching on them. Furthermore, the frame may have slits to allow birds to escape easily if they get caught, for example, it may have slits 6 (Figure 4) in the ring-shaped bird repellent.

[0011] The bird damage prevention device 21 of the present invention comprises a plurality of bird damage prevention bodies, each consisting of a bird damage prevention body 3 fixed to a core wire 1 (Figure 4) and a bird damage prevention body 4 movable along the core wire 1. More preferably, the two are attached alternately to the core wire 1 in a ratio of 1 to 1 or 2, and even more preferably, they are attached alternately to the core wire 1 in a 1:1 ratio. When the bird damage prevention bodies rotate and stand upright to form a three-dimensional bird damage prevention device, a larger proportion of the movable bird damage prevention bodies 4 along the core wire 1 results in a denser arrangement of bird damage prevention bodies in three dimensions, but this increases the number of bird damage prevention bodies and makes the device somewhat bulkier. Considering this balance, it is even more preferable to attach them alternately to the core wire 1 in a 1:1 ratio. The bird-repellent body 3, fixed to the core wire 1, may be attached to the core wire 1 using a fastener 7, or the bird-repellent body and the fastener 7 may be integrated and fixed to the core wire 1 with this integrated fastener 7 (the fastener 7 is such a fastener), or the bird-repellent body may be integrated with the core wire 1. For example, if the bird-repellent body is integrated with the fastener 7, the fastener, which is divided into upper and lower halves with the vertical axis of the bird-repellent body 3, is joined to form a fastener 7 that forms a hole smaller in diameter than the core wire 1, and each of these upper and lower halves of the fastener is integrated with the left and right bird-repellent bodies of the core wire 1, respectively. By joining the upper and lower halves of the fastener so as to sandwich the core wire 1, the left and right bird-repellent bodies are joined together and a hole smaller in diameter than the core wire 1 is formed, fixing the bird-repellent body to the core wire 1. The bird-repellent body 4, which is movable along the core wire 1, is attached to the core wire 1 so that it can move in the direction of the core wire, that is, in the direction of the arrow in Figure 4 and in the opposite direction. For example, while having a structure that clamps the core wire 1, similar to the fixing device 7, the hole formed when clamping the core wire 1 is made thicker than the core wire 1 to allow movement in the direction of the core wire, and this can be used as a core wire mounting device (the part of the mounting device / tension wire fixing device 8 that clamps the core wire 1 corresponds to this). There are no particular restrictions on the material of the core wire 1; for example, metal, resin, or metal coated with resin may be used.

[0012] Furthermore, the bird damage prevention device 21 of the present invention includes a guide device that rotates one bird damage prevention device relative to the other when adjacent bird damage prevention devices approach each other. The guide device has a guide path that guides the bird damage prevention devices. For example, the guide device has a groove or an outer edge, and the bird damage prevention device rotates and stands up as it is guided along it. The guide device converts the force that brings the bird damage prevention devices closer together into a force that causes the bird damage prevention devices to rotate and stand up. The guide device may exist independently, or other components may perform the same function. For example, in Figure 4, the bird-repellent body 3, which is fixed to the core wire 1 in part, acts as a guide, becomes narrower in spacing and thicker in thickness as it approaches the figure-eight cross section (see also Figure 5, which clearly shows the change in thickness). The narrower the spacing and the thicker the thickness, the more the bird-repellent body 4 is guided towards the outer edge of the bird-repellent body 3 and tilts. As a result, the bird-repellent body 4, which is movable along the core wire 1, tilts more and more as it approaches the bird-repellent body 3 fixed to the core wire 1, being guided towards the outer edge of the fixed bird-repellent body 3 (Figure 4(A)⇒(B)). Furthermore, the mounting fixture and tension wire fixing fixture 8 of the bird-repellent body 4, which is movable along the core wire 1, fits into the figure-eight cross section of the bird-repellent body 3 fixed to the core wire 1, causing it to stand upright (Figure 4(B)⇒(C)). To explain Figure 4 in more detail, adjacent bird-repellent devices are placed with the upper and lower parts of the two figure-eight rings overlapping alternately (Figure 4(A)), and the adjacent rings are brought closer together. Then, according to the above reasoning, a part of one ring body acts as a guide, causing the other ring body to stand upright and move closer (Figure 4(B)), and finally, the crossing parts of the figure-eight shapes of the two ring bodies fit together, causing the other ring to stand up almost vertically, and the bird-repellent device becomes three-dimensional (Figure 4(C)). The crossing part may be formed by the ring body, the fixing device 7, and the attachment / tension fixing device 8 individually, or some of these may be integrated to form the crossing part. For example, in the bird-repellent device 3 of Figure 4, the ring body and the fixing device 7 are integrated to form the crossing part. Note that standing upright does not only mean that one bird-repellent device remains stationary while only the other rotates and stands upright, but also that one bird-repellent device stands upright relative to the other bird-repellent device. Further, a screw groove with a gently sloped inclination is provided on the core wire 1 as a guiding path, and a structure is adopted in which the figure-eight cross portion of the bird damage prevention body 4 movable along the core wire 1 engages with the screw groove. By bringing the bird damage prevention bodies closer to each other, the bird damage prevention body 4 movable along the screw groove of the core wire 1 may be rotated and erected. The movable bird damage prevention body 4 attached to the core wire 1 is not erected when being carried, so the bird damage prevention device is in a flat plate shape and easy to carry. During use, since the bird damage prevention body is erected by the guiding device, when the bird damage prevention device is wound around a linear body 5 such as an electric wire, the bird damage prevention bodies are arranged more closely in a three-dimensional manner, and bird damage can be more effectively prevented.

[0013] When the guiding device also serves as other components, a part of the bird damage prevention body may serve as the guiding device as in the above example. For example, the core wire 1, the tension wire 2 to be described later, the fixing device 7, and the attachment device and tension wire fixing device 8 may also serve as the guiding device. Also, a plurality of these components may integrally form the guiding device.

[0014] In the present invention, the mechanism for bringing adjacent bird damage prevention bodies closer to each other is not particularly limited. For example, as follows, it may be achieved by providing a tension wire 2 (Fig. 4).

[0015] The tension wire 2 is parallel to the core wire 1 (Figs. 1 and 4) in a state of approaching each other. A bird damage prevention body 4 movable along the core wire 1 is fixed to this tension wire. More preferably, all the bird damage prevention bodies 4 movable along the core wire 1 are fixed to the tension wire 2. For fixing, for example, a tension wire fixing tool that forms a hole smaller than the diameter of the tension wire 2 and sandwiches it may be used. In Fig. 4, the portion of the attachment device and tension wire fixing device 8 that sandwiches the tension wire 2 corresponds to this, and the attachment device and tension wire fixing device 8 is an attachment device that is movably attached to the core wire 1 and a fixing device to the tension wire 2 integrated into one attachment device and tension wire fixing device 8. By pulling or pushing the pull wire 2, the movable bird-repellent body 4 can be moved, and conversely, by pulling or pushing the core wire 1, the bird-repellent body 3 fixed to the core wire 1 can be moved, bringing the two closer together and allowing the bird-repellent body to stand upright.

[0016] When attaching bird deterrents that are fixed alternately in a 1:1 ratio and movable bird deterrents to the core wire as shown in Figures 1-3, there is one pull wire 2. If the ratio is 1:2, there are two pull wires 2.

[0017] If bird-repellent bodies 4, which are movable along the core wire 1, are connected via a pull wire 2, then when one bird-repellent body is rotated and raised by a guide, another bird-repellent body fixed to the same pull wire 2 will also rotate and raise. Therefore, it can be said that a guide is sufficient for each group of connected bird-repellent bodies. However, more preferably, multiple guides are provided to smoothly rotate and raise the bird-repellent bodies, for example, guides are provided to accommodate all bird-repellent bodies that are movable along the core wire 1.

[0018] The mechanism for bringing adjacent bird-repellent devices closer together may be achieved by pulling out the bird-repellent device 21 of the present invention in the longitudinal direction from the cylindrical packaging material, so that only one of the bird-repellent device 3 fixed to the core wire 1 or the bird-repellent device 4 that can move along the core wire 1 moves, thereby bringing the two closer together. In other words, the bird-repellent body 3, which is fixed to the core wire 1, is temporarily fixed to the inside of the packaging material. When removing the bird-repellent device from the packaging material, pulling the pull wire 2 causes only the bird-repellent body 4, which is movable along the core wire 1 fixed to the pull wire 2, to move towards the opening. The bird-repellent body 3, which is temporarily fixed to the packaging material and fixed to the core wire 1, does not move, so the two move closer together. As they move closer together and join, the movable bird-repellent body 4 rotates and stands upright. If pulled further, the bird-repellent body 3 fixed to the core wire 1 also starts to move, the temporary fixing is released, and the three-dimensional bird-repellent device is pulled out from the packaging material. Conversely, a bird-repellent device 4 that can move along the core wire 1 may be temporarily fixed in place, and the core wire 1 may be pulled.

[0019] Once the bird-repellent bodies approach each other and stand upright, they can maintain that position due to friction with guides and the like. However, to eliminate the possibility of the bird-repellent bodies returning to their original position and becoming flat again, it is preferable to have a stopper to prevent the approaching bird-repellent bodies from separating again. It is preferable to form the stopper on the part where the bird-repellent body is connected to the core wire 1. For example, the fixing device 7 (Figure 6) can be provided with a notch 11 that gradually becomes shallower and a groove 12 that follows it, and the other bird-repellent body can be provided with a claw 13 on the part where it is connected to the core wire 1. As the mounting device / tension wire fixing device 8 and the fixing device 7 approach each other, the mounting device / tension wire fixing device 8 stands upright relative to the fixing device 7, and the claw 13 is guided into the notch 11 and recessed. When the claw reaches the groove 12, the claw 13 pops out and fits into the groove 12.

[0020] 2. Manufacturing method (1) The core wire 1 is required to have strength and durability because it will be pulled or wrapped around the wire body 5 for long-term use. For example, it is manufactured by coating a string-like metal core with resin. (2) The pull wire 2 needs to be strong enough to pull the bird repellent. For example, it can be manufactured by coating a core string-like metal with resin. (3) If the bird repellent body and the fixing device 7 are made of resin, they may be manufactured by injection molding using a mold, or by performing secondary processing such as cutting after primary molding. The same method can also be used when the bird repellent body and the fixing device 7 are integrally molded. (4) After manufacturing each component, the bird damage prevention device 21 is assembled by attaching the bird damage prevention body to the core wire 1 using the fastener 7. It can be manufactured in this way.

[0021] 3.How to use The bird damage prevention device 21 of the present invention is carried to a high place in its flat form, and at the high place the core wire 1 and the tension wire 2 are shifted in opposite directions to form a three-dimensional shape, and then it is used by wrapping it around a linear body 5 such as an electric wire. [Industrial applicability]

[0022] The bird damage prevention device 21 of the present invention is highly effective in preventing bird damage, is not bulky and easy to handle when transporting it to high places such as power lines, and is therefore useful for the power and telecommunications industries, which suffer from bird damage.
