Description
Technical Field
[0001] The utility model relates to the field of railways, and more specifically, to a bird repellent device for railway catenaries. Background Art
[0002] The catenary boom is an important component in the catenary system, mainly used for hanging and supporting the contact wire to keep it at a certain height and horizontal position to ensure the normal operation of electric locomotives. Since railway catenary equipment is usually located in open areas, and equipment such as power supply poles often becomes the tallest building in the surrounding environment, birds will choose such high buildings to build nests in order to forage and avoid natural enemies.
[0003] During the nest-building process of birds, the insulation distance between the energized body and the grounded body is reduced or short-circuited through the body or nest materials of the birds, resulting in problems such as grounding tripping, even wire breakage, and insulator breakdown. Since equipment such as power supply poles is usually located in open areas, operators cannot always monitor whether there are bird nests on the surface of the railway catenary. Usually, when it is discovered, the birds have already completed nest-building. At this time, after the bird nest is manually removed, the birds will show extremely high persistence and usually choose to rebuild the nest in the original place or nearby areas. This behavior pattern not only increases the difficulty of bird damage prevention but also poses a continuous threat to the safe and stable operation of railway power supply facilities. How to solve these problems has become an urgent problem for those skilled in the art. Summary of the Utility Model

Detailed implementation manners
[0028] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Refer to Figures 1 - 5 , a bird repellent device for railway catenary, including a support pillar 1, a cantilever base 2 installed on the outer wall of the support pillar 1, and a cantilever insulator 3 installed on the outer wall of the cantilever base 2. A bird repellent component 4 is installed on the top of the cantilever base 2, and an auxiliary component 5 is arranged on the outer wall of the bird repellent component 4.
[0030] The bird repellent component 4 includes a movable base 401, a sliding rod 402, a trapezoidal plate 403, a support spring 404, a pressing member 405, a pressure switch 406, a buzzer 407 and a power supply 408. The movable base 401 is installed on the top of the cantilever base 2. The sliding rod 402 is arranged on the top of the movable base 401. The bottom end of the sliding rod 402 penetrates through the top of the movable base 401 and extends below the movable base 401. The outer wall of the sliding rod 402 is slidably connected to the inner wall of the movable base 401 penetrated. The trapezoidal plate 403 can move on the top of the movable base 401 through the sliding rod 402. The trapezoidal plate 403 is fixedly connected to the top end of the sliding rod 402. The support spring 404 is fixedly connected to the bottom of the trapezoidal plate 403. The bottom of the support spring 404 abuts against the top of the movable base 401. The existence of the support spring 404 can push the trapezoidal plate 403 to reset. The pressing member 405 is fixedly connected to the top of the trapezoidal plate 403. The pressure switch 406 is installed on the top of the movable base 401. The buzzer 407 is fixedly connected to the outer wall of the movable base 401. The power supply 408 is fixedly connected to the outer wall of the movable base 401. The buzzer 407 is electrically connected to the power supply 408 through the pressure switch 406. After the pressure switch 406 is triggered, it can control the power supply 408 to supply power to the buzzer 407.
[0031] By setting the pressing member 405 and the pressure switch 406, when the load on the trapezoidal plate 403 increases, it will push the pressing member 405 down and trigger the pressure switch 406. At this time, the power supply 408 supplies power to the buzzer 407, and the buzzer 407 generates noise, thereby driving away the birds; this solves the problem that the existing bird-driving methods cannot drive away the birds before they complete nesting. At the same time, a support spring 404 is installed at the bottom of the trapezoidal plate 403. Therefore, the trapezoidal plate 403 has a certain load-bearing capacity, which can avoid false triggering and prevent a large number of birds from accumulating on the surface of the trapezoidal plate 403. When the birds leave the trapezoidal plate 403, the trapezoidal plate 403 will reset under the action of the support spring 404, and the power supply 408 will stop supplying power to the buzzer 407 to prevent the birds from developing resistance to the noise.
[0032] The auxiliary component 5 includes a gear 501, a movable rod 502, a swing plate 503, a counterweight 504, a knocking member 505, a striking plate 506 and a limiting rod 507. The gear 501 is installed on the outer wall of the movable base 401. The movable rod 502 is fixedly connected to the bottom of the trapezoidal plate 403. A tooth groove is formed inside the movable rod 502, and the gear 501 meshes with the tooth groove. When the trapezoidal plate 403 moves, it can drive the gear 501 to rotate through the movable rod 502. The swing plate 503 is installed on the outer wall of the movable base 401, and the swing plate 503 is rotatably connected to the outer wall of the movable base 401. The swing plate 503 can rotate on the outer wall of the movable base 401. The counterweight 504 is fixedly connected to the bottom of the swing plate 503. The knocking member 505 is fixedly connected to the top of the swing plate 503. The striking plate 506 is fixedly connected to the outer wall of the movable base 401. The knocking member 505 contacts the striking plate 506. After the swing plate 503 rotates to a certain angle, the counterweight 504 will drive the swing plate 503 to reset and drive the knocking member 505 to collide with the striking plate 506, generating vibration. The limiting rod 507 is fixedly connected to the outer wall of the movable base 401.
[0033] The gear 501 is composed of a round wheel 5011, a bent rod 5012, gear teeth 5013, a torsion spring 5014 and a baffle 5015. The round wheel 5011 is located on the outer wall of the movable base 401, and the round wheel 5011 is rotatably connected to the movable base 401. The bent rod 5012 is fixedly connected to the outer wall of the round wheel 5011. The gear teeth 5013 are located on the outer wall of the round wheel 5011. The bent rod 5012 penetrates the gear teeth 5013 and is rotatably connected to the inner wall of the gear teeth 5013. The gear teeth 5013 can rotate on the outer wall of the bent rod 5012. When the circular wheel 5011 drives the gear teeth 5013 to revolve, it will push the swing plate 503 to rotate. The torsion spring 5014 is fixedly connected to the outer wall of the gear teeth 5013. The two sides of the torsion spring 5014 are respectively fixedly connected to the outer wall of the gear teeth 5013 and the outer wall of the bent rod 5012. The existence of the torsion spring 5014 can pull the gear teeth 5013 to reset. The baffle 5015 is fixedly connected to the outer wall of the circular wheel 5011. The existence of the baffle 5015 can limit the rotation angle of the gear teeth 5013.
[0034] By setting the gear 501 and the striking plate 506, when the trapezoidal plate 403 moves, the gear 501 can be driven to rotate through the tooth grooves on the surface of the movable rod 502. When the gear 501 rotates, it will push the swing plate 503 to rotate. When the gear 501 is separated from the swing plate 503, the swing plate 503 will drive the striking piece 505 to collide with the striking plate 506 under the action of the counterweight block 504, thereby assisting the buzzer 407 to drive away birds.
[0035] The working principle of the bird-repelling device for a railway contact network is as follows: when a large number of birds stay on the top of the trapezoidal plate 403, the trapezoidal plate 403 will descend under the trend of the weight of the birds. When the trapezoidal plate 403 descends, it will drive the pressing piece 405 to move downward until the pressing piece 405 contacts the pressure switch 406 and triggers the pressure switch 406, so that the power supply 408 supplies power to the buzzer 407, thereby generating noise, and driving away the large number of birds resting on the top of the trapezoidal plate 403. At the same time, when the trapezoidal plate 403 descends, the gear 501 is driven to rotate through the movable rod 502, and the gear 501 pushes the swing The movable plate 503 rotates, and when the gear 5013 separates from the swing plate 503, the swing plate 503 will be reset under the action of the counterweight block 504, and the knocking piece 505 will collide with the striking plate 506, thereby cooperating with the buzzer 407 to drive away birds; if birds build nests on the top of the trapezoidal plate 403, the trapezoidal plate 403 will move under the action of the bird's nest, and start the buzzer 407 through the pressing piece 405, and at the same time drive the swing plate 503 to rotate through the gear 501, so that the knocking piece 505 collides with the striking plate 506, and the buzzer 407 is used to drive away birds.
[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
