Description

Technical Field

[0001] The utility model relates to the technical field of bird repelling for cross arms, in particular to a bird repelling device for cross arms. Background Art

[0002] With the rapid development of China's power industry, in the construction and transformation of transmission lines, except for some transmission lines being changed to cable laying, most transmission lines still adopt the overhead form. The power line cross arm is an important part of the pole tower. Its function is to install insulators and fittings to support the conductors and lightning conductors and keep a certain safe distance as required.

[0003] With the sound development of China's ecological environment in recent years, a large number of birds gather near the power transmission lines. It is found that birds standing on the cross arms of the lines to move or even build nests will cause grounding faults in the energized parts, and even burn the birds to death by electric discharge. At the same time, the electric arc causes the line to break. For example, in the patent named "A Double Cross Arm with Bird Repelling Function" with the publication number of CN110037009A, a cleverly designed, simple-structured and low-cost device is designed. By blocking the intersection of the cross arm and the telegraph pole, there is no support for birds to build nests, fundamentally solving the problem of bird damage.

[0004] Since the telegraph poles for power transmission are generally set in unmanned jungles where there are many birds, there are still reserved positions on the transverse ends of the existing first cross arm and second cross arm, which can also provide positions for birds to build nests. Therefore, there is still a hidden danger of line damage. Content of the Utility Model

A sprocket 14 is fixedly installed on the shaft rod 12 and on one side of the cam 13. Chains 15 are connected between the sprockets 14. A motor 16 is fixedly installed on the outer front wall surface of the bearing box 3. The motor 16 is fixedly connected to the shaft rod 12;

[0022] Start the motor 16. The driving end of the motor 16 drives the shaft rod 12 to rotate. Since the shaft rods 12 are connected by the sprockets 14 and the chains 15, when one of the plurality of shaft rods 12 rotates, the rest of the shaft rods 12 rotate simultaneously. The shaft rod 12 drives the cam 13 to rotate, so that the eccentric end of the cam 13 reciprocally strikes the baffle 9. The baffle 9 pushes the first support rod 7 and the second support rod 8, so that the first support rod 7 and the second support rod 8 push the hammer head 10, and the hammer head 10 moves up and down reciprocally, thereby striking the bearing plate 6, and further driving away the birds on the bearing plate 6.

[0024] In this embodiment, it is further set that the trigger assembly includes a moving rod 17. A through hole is formed at the upper end of the cylinder body 5. The moving rod 17 passes through the through hole. A piston plate 18 is fixedly installed at the lower end of the moving rod 17.

[0025] The bearing plate 6 pushes the moving rod 17 downward. The moving rod 17 pushes the piston plate 18. The piston plate 18 squeezes the second spring 19, so that the second spring 19 is compressed under force. The piston plate 18 pushes the trigger rod 20 downward until the trigger rod 20 contacts the pressure sensor 21.

[0026] In this embodiment, it is further set that a protective box 22 is fixedly installed on the front wall surface outside the bearing box, and the motor 16 is located inside the protective box 22.

[0029] Embodiment: As can be seen from the accompanying drawings of the specification, the motor 16 and the pressure sensor 21 are electrically connected to an external controller respectively. When in use, when a bird lands on the cross arm 2, the bird first lands on the bearing plate 6. The bearing plate 6 pushes the moving rod 17 downward. The moving rod 17 pushes the piston plate 18. The piston plate 18 squeezes the second spring 19, so that the second spring 19 is compressed under force. The piston plate 18 pushes the trigger rod 20 downward until the trigger rod 20 contacts the pressure sensor 21. The pressure sensor 21 detects a pressure signal and transmits the signal to the external controller. The external controller controls the motor 16 to start. The driving end of the motor 16 drives the shaft rod 12 to rotate. Since the shaft rods 12 are connected by a sprocket 14 and a chain 15, when one of the several shaft rods 12 rotates, the rest of the shaft rods 12 rotate simultaneously. The shaft rod 12 drives the cam 13 to rotate, so that the eccentric end of the cam 13 repeatedly knocks on the baffle 9. The baffle 9 pushes the first support rod 7 and the second support rod 8, so that the first support rod 7 and the second support rod 8 push the hammer head 10. The hammer head 10 moves up and down reciprocally, and then knocks on the bearing plate 6, thereby driving away the birds on the bearing plate 6.
