Due to the inherent habits of birds, they often look for a foothold to stay or build nests at high places. Especially, the number of larger birds is increasing year by year. Once birds drop bird droppings on the insulators of the electric tower, it is extremely easy to cause a short circuit of the line, frequent line failures, and greatly affect the safe operation of the line;

[0003] For example, an insulating anti-bird guard plate with the patent publication number of CN202022251715.8 includes the cross arm of a transmission line tower. The cross arm has a quadrilateral cross-section, and the tops at both ends of the cross arm are inclined downward. Two groups of intermediate anti-bird guard plate components are symmetrically installed and slidably arranged in the middle of the cross arm, and side anti-bird guard plate components are respectively slidably installed at both ends of the cross arm; the rectangular baffle of the intermediate anti-bird guard plate component, the triangular baffle, the movable baffle, and the inclined baffle of the side anti-bird guard plate component are respectively slidably connected to the cross arm through slide rails, and pins for sliding and locking on the slide rails are respectively provided on the rectangular baffle, the triangular baffle, the movable baffle, and the inclined baffle;

[0004] Since the above-mentioned insulating anti-bird guard plate is connected to the transmission tower through a connecting piece, but the insulating anti-bird guard plate is fixedly connected to the transmission tower, which causes birds to be able to temporarily rest on the edge of the insulating anti-bird guard plate, bringing certain adverse effects to the actual use. Therefore, improvements are needed. Content of the Utility Model

The utility model can be installed on the transmission tower by adjusting the mounting seat, so as to freely disassemble, replace, and clean the anti-bird guard plate, and change and adjust the inside of the anti-bird guard plate into a buffer swing form, so as to achieve the effects of stable adaptation of the anti-bird guard plate to the transmission tower during disassembly and assembly and smooth guiding and discharging in a swinging manner, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An insulating anti-bird protection plate for a transmission tower, comprising a placement plate, a regulating mounting seat is fixedly connected to the bottom of the placement plate, an arc-shaped sliding groove is opened at the top of the regulating mounting seat, a sliding plate is slidably connected to the inner wall of the arc-shaped sliding groove, a tension spring is connected between the surface of the sliding plate and the side surface of the inner wall of the arc-shaped sliding groove through a damping pad, a buffer protection cover is fixedly connected to the top of the sliding plate, a clamping groove is opened at the top of the buffer protection cover, a smooth anti-bird plate is clamped in the inner wall of the clamping groove, and positioning screws are threadedly connected to the inside of the clamping groove and the inside of the smooth anti-bird plate through internal thread grooves.

Through the setting of the elastic sealing sleeve, the effect of external dust protection can be achieved. At the same time, the weight of the bird will cause the buffer cover to swing in an arc on the top of the placement plate, that is, the sliding plate in the buffer cover will smoothly slide in the arc-shaped chute. Through the setting of the tension spring, the effects of elastic compression, stretching, and subsequent elastic reset can be achieved, enabling the bird-proof shield to smoothly discharge the swing after being impacted by the falling bird, enhancing the swing discharge effect of the bird-proof shield on the transmission tower.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Example 1 Please refer to Figures 1 - 4 , the present invention provides a technical solution:

[0025] An insulating anti-bird guard plate for a transmission tower includes a placing plate 1. The bottom of the placing plate 1 is fixedly connected with an adjusting mounting seat 2. The top of the adjusting mounting seat 2 is provided with an arc-shaped chute 3. The inner wall of the arc-shaped chute 3 is slidably connected with a sliding plate 4. The surface of the sliding plate 4 and the side surface of the inner wall of the arc-shaped chute 3 are connected with a tension spring 5 through a damping pad. The top of the sliding plate 4 is fixedly connected with a buffer guard 6. The top of the buffer guard 6 is provided with a clamping groove 7. The inner wall of the clamping groove 7 is clamped with a smooth anti-bird plate 8. The inside of the clamping groove 7 and the inside of the smooth anti-bird plate 8 are both threadedly connected with a positioning screw 9 through an internal thread groove.

[0026] Specifically, as Figures 1 - 4As shown in the figure, the main body of the adjustment mounting base 2 is a restraint frame. An adjustment cavity is provided inside the restraint frame. The bottom of the inner wall of the adjustment cavity is rotatably connected to an adjustment screw rod 10 through a bearing. A threaded sleeve plate 11 is threadedly connected to the surface of the adjustment screw rod 10. A limiting component is connected to the surface of the threaded sleeve plate 11. A lower magnetic attraction clamping plate 12 is clamped on the surface of the threaded sleeve plate 11. A upper magnetic attraction clamping plate 13 is fixedly connected to the restraint frame near the top of its inner wall. A non-slip rotation ball 14 is fixedly connected to the bottom of the adjustment screw rod 10. A wear-resistant coating is filled on the surface of the non-slip rotation ball 14. The limiting component includes a limiting plate 15 and a limiting groove 16. The limiting plate 15 is fixedly connected to the side surface of the threaded sleeve plate 11. The limiting groove 16 is provided on the surface of the inner wall of the restraint frame. The inner wall of the limiting groove 16 and the surface of the limiting plate 15 are slidably connected. The restraint frame on the adjustment mounting base 2 forms a clamping effect on the main body. Then, by adjusting the distance between the upper magnetic attraction clamping plate 13 and the lower magnetic attraction clamping plate 12, the effect of clamping the upper bracket of the transmission tower is completed. That is, rotating the non-slip rotation ball 14 can drive the adjustment screw rod 10 to rotate. Through the setting of the limiting plate 15 and the limiting groove 16, the movement track of the threaded sleeve plate 11 is limited, so that the rotation of the threaded rod can drive the threaded sleeve plate 11 to move. The movement of the threaded sleeve plate 11 can drive its upper and lower magnetic attraction clamping plates 12 to move. It can be made that the lower magnetic attraction clamping plate 12 moves upward to approach the upper magnetic attraction clamping plate 13, and the positioning restraint of the whole bird-proof guard plate can be completed.

[0027] Example 2 Please refer to Figures 1 - 4 , the difference between this embodiment and Embodiment 1 is that: the bottom of the buffer guard 6 is a lower arc plate 17. A spring telescopic rod 18 is fixedly installed on the top of the lower arc plate 17. One end of the spring telescopic rod 18 is fixedly connected to an upper arc plate 19. A limiting lifting plate 20 is fixedly connected to the bottom of the upper arc plate 19. A limiting lifting groove 21 is provided on the surface of the top of the lower arc plate 17. The inner wall of the limiting lifting groove 21 and the surface of the limiting lifting plate 20 are slidably connected. An elastic sealing sleeve 22 is fixedly connected to the surface of the upper arc plate 19 near its side surface. The surface of the elastic sealing sleeve 22 and the surface of the lower arc plate 17 near its side surface are fixedly connected. Because the smooth bird-proof plate 8 has a smooth surface, it can prevent birds from standing steadily. And because of the weight of the birds, the limiting lifting plate 20 in the upper arc plate 19 will smoothly lift and lower in the limiting lifting groove 21, increasing the effect that the spring telescopic rod 18 can play an elastic buffering role. Through the setting of the elastic sealing sleeve 22, the effect of external dust protection can be achieved. At the same time, the weight of the birds will cause the buffer guard 6 to swing in an arc on the top of the placing plate 1. That is, the sliding plate 4 in the buffer guard 6 smoothly slides in the arc-shaped chute 3. Through the setting of the tension spring 5, the effects of elastic compression and stretching and subsequent elastic reset can be achieved, so that the bird-proof guard plate can smoothly discharge after swinging when being impacted by the falling birds.

[0028] Working principle of the utility model: When in use, the staff can place the placing plate 1 on the anti-bird installation position of the transmission tower, and then use the restraint frame on the adjusting mounting seat 2 to form the clamping effect of the main body. Then, by adjusting the distance between the upper magnetic clamping plate 13 and the lower magnetic clamping plate 12, the effect of clamping the upper bracket of the transmission tower is completed. That is, rotating the anti-slip rotating ball 14 can drive the adjusting screw rod 10 to rotate. Through the setting of the limiting plate 15 and the limiting groove 16, the movement track of the threaded sleeve plate 11 is limited, so that the rotation of the threaded rod can drive the threaded sleeve plate 11 to move. The movement of the threaded sleeve plate 11 can drive its upper and lower magnetic clamping plates 12 to move, so that the lower magnetic clamping plate 12 can move upward to approach the upper magnetic clamping plate 13, and the positioning constraint of the entire anti-bird guard plate can be completed. If a bird perches on the anti-bird guard plate, the bird will first land on the smooth anti-bird plate 8 on the outside. Because the smooth anti-bird plate 8 is a smooth surface, it can prevent the bird from standing steadily. And due to the weight of the bird, the limit lifting plate 20 in the upper arc plate 19 will move up and down smoothly in the limit lifting groove 21, and the spring telescopic rod 18 can play an elastic buffering effect. Through the setting of the elastic sealing sleeve 22, the effect of external dust protection can be achieved. At the same time, the weight of the bird will cause the buffer cover 6 to swing in an arc on the top of the placing plate 1, that is, the sliding plate 4 in the buffer cover 6 slides smoothly in the arc-shaped chute 3. Through the setting of the tension spring 5, the effects of elastic compression and stretching and subsequent elastic reset can be achieved, so that the anti-bird guard plate can swing smoothly and drain down after being hit by the bird, enhancing the smooth adaptation, disassembly and assembly of the anti-bird guard plate on the transmission tower and the effect of swinging and draining down.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
