Description

Technical Field

[0001] This utility model belongs to the field of protective covers, specifically relating to a bird-proof protective cover for insulators. Background Technology

[0002] Bird shields are specially designed protective devices primarily used in power systems, agriculture, and other fields to prevent bird activity from damaging facilities or crops through physical isolation or deterrence.

[0003] The existing device connection structure lacks a guiding design, requiring precise alignment or forceful manipulation during installation, which is laborious. The wire through hole may be a smooth round hole, leaving a gap between the wire and the hole wall when the wire passes through. Birds can easily fly into the protective cover through the gap to nest and defecate, thus polluting or damaging the insulator. Utility Model Content

[0004] To overcome the problems of existing technologies where the device connection structure lacks a guiding design, requires precise alignment or forceful manipulation during installation, is laborious, and the wire through-hole may be a smooth round hole, leaving gaps between the wire and the hole wall, allowing birds to easily fly into the protective cover to nest, defecate, and contaminate or damage the insulator, a bird-proof protective cover for insulators is proposed.

[0005] The technical solution of this utility model is as follows: an insulator bird protection cover, comprising a first hemisphere and a locking mechanism provided on the inner wall of the first hemisphere, a second hemisphere provided on one side of the first hemisphere, a slot mechanism provided on the inner wall of the second hemisphere, and a sealing mechanism provided on the inner walls of the first and second hemispheres.

[0006] Furthermore, the locking mechanism includes a first fixed block fixed to both sides of the inner wall of the first hemisphere, a sliding block fixed to the side of the first fixed block near the second hemisphere, and a third slot hole through which one end of the sliding block is formed.

[0007] Furthermore, the slot mechanism includes a second fixing block fixedly connected to both sides of the inner wall of the second hemisphere, a first slot opening on the side of the second fixing block near the first hemisphere, a second slot opening on both sides of the inner wall of the first slot, one end of a first spring fixedly connected to the inner wall of the second slot, and a limit block fixedly connected to the other end of the first spring.

[0008] Furthermore, the sealing mechanism includes a third fixing block fixed to the inner wall of the first hemisphere, a fourth slot opening on the side of the third fixing block near the second hemisphere, a fifth slot opening on the inner wall of the fourth slot, one end of a second spring fixed to the inner wall of the fifth slot, and a clamping block fixed to the other end of the second spring.

[0009] Furthermore, the lower end of the sliding block is provided with an arc surface, and the side of the limiting block near the sliding block is provided with an arc surface.

[0010] Furthermore, the first and second hemispheres are distributed vertically, and both hemispheres are spherical.

[0011] Furthermore, two sealing mechanisms are fixed to the inner walls of both the first and second hemispheres, and the sealing mechanisms of the inner walls of the first and second hemispheres are symmetrical about the plane at the connection point between the first and second hemispheres.

[0012] The beneficial effects of this utility model are:

[0013] 1. By pressing the limiting block with the sliding block, and using the first spring to push the limiting block into the third slot, a mechanical locking fixation is formed, making the connection between the first hemisphere and the second hemisphere more stable and less likely to detach due to external force.

[0014] 2. The side walls of the sliding block and the limiting block are designed with arc surfaces. The arc surface contact reduces the squeezing resistance, making it easier for the sliding block to smoothly squeeze the limiting block and reducing the difficulty of installation.

[0015] 3. With the help of four clamping blocks and a second spring, the clamping blocks are squeezed when the wire passes through. The spring reaction force makes the clamping blocks tightly wrap the wire, eliminating the gap in the through hole and effectively preventing birds from entering. The clamping blocks can adapt to wires of different diameters within a certain range through the elastic deformation of the second spring, and always maintain a stable clamping force.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: an insulator bird protection cover, including a first hemisphere 1 and a locking mechanism 2 provided on the inner wall of the first hemisphere 1, a second hemisphere 5 provided on one side of the first hemisphere 1, a slot mechanism 3 provided on the inner wall of the second hemisphere 5, and a sealing mechanism 4 provided on the inner walls of the first hemisphere 1 and the second hemisphere 5.

[0024] In use, the wire is first placed in the through hole of the first hemisphere 1. Then, the slot mechanism 3 inside the second hemisphere 5 is connected to the block mechanism 2 inside the first hemisphere 1. The sliding block 22 is pressed into the first slot 32. When the sliding block 22 is pressed against the side wall of the limiting block 35, the lower end of the sliding block 22 and the side wall of the limiting block 35 are curved, which facilitates the sliding block 22 pressing against the limiting block 35. When the sliding block 22 presses against the limiting block 35, the limiting block 35 presses against the first spring 34. When the limiting block 35 is pressed into the second slot 33, the sliding block 22 enters the first slot. Inside 32, the limiting block 35 is flush with the third slot 23. Then, the first spring 34 pushes the limiting block 35 into the interior of the third slot 23. The limiting block 35 fixes the second fixing block 31 and the first fixing block 21 together. The wire passes through the through hole of the first hemisphere 1 and the second hemisphere 5. The wire squeezes the clamping block 45, and the clamping block 45 squeezes the second spring 44. The second spring 44 exerts a reaction force on the clamping block 45. The four clamping blocks 45 clamp the wire to prevent birds from flying into the interior of the first hemisphere 1 and the second hemisphere 5 through the through hole.

[0025] Please see Figure 3 In this embodiment, the locking mechanism 2 includes a first fixing block 21 fixed to both sides of the inner wall of the first hemisphere 1, and a sliding block 22 fixed to the side of the first fixing block 21 near the second hemisphere 5. One end of the sliding block 22 is provided with a third slot 23, which facilitates the fixed connection between the first hemisphere 1 and the second hemisphere 5.

[0026] Please see Figure 4 In this embodiment, the slot mechanism 3 includes a second fixing block 31 fixed to both sides of the inner wall of the second hemisphere 5. The second fixing block 31 has a first slot 32 on the side near the first hemisphere 1. The inner walls of the first slot 32 have second slots 33 on both sides. One end of the first spring 34 is fixed to the inner wall of the second slot 33. The other end of the first spring 34 is fixed to a limit block 35. The first spring 34 and the limit block 35 cooperate to limit the sliding block 22.

[0027] Please see Figure 5In this embodiment, the sealing mechanism 4 includes a third fixing block 41 fixed to the inner wall of the first hemisphere 1, a fourth slot 42 opened on the side of the third fixing block 41 near the second hemisphere 5, a fifth slot 43 opened on the inner wall of the fourth slot 42, one end of a second spring 44 fixed to the inner wall of the fifth slot 43, and a clamping block 45 fixed to the other end of the second spring 44. The second spring 44 clamps the clamping block 45 to the wire, thereby increasing the internal sealing of the first hemisphere 1 and the second hemisphere 5.

[0028] Please see Figure 3 In this embodiment, the lower end of the sliding block 22 is provided with an arc surface, and the side of the limiting block 35 near the sliding block 22 is provided with an arc surface. The arc surface facilitates the lower end of the sliding block 22 to press against the sliding block 22.

[0029] Please see Figure 2 In this embodiment, the first hemisphere 1 and the second hemisphere 5 are distributed vertically, and the first hemisphere 1 and the second hemisphere 5 are spherical. The spherical shape can reduce the need for birds to stand.

[0030] Please see Figure 2 In this embodiment, two sealing mechanisms 4 are fixedly connected to the inner walls of the first hemisphere 1 and the second hemisphere 5. The sealing mechanisms 4 on the inner walls of the first hemisphere 1 and the second hemisphere 5 are symmetrical about the plane at the connection point of the first hemisphere 1 and the second hemisphere 5. The sealing mechanisms 4 on the inner walls of the first hemisphere 1 and the second hemisphere 5 cooperate with each other to increase the sealing between the first hemisphere 1 and the second hemisphere 5.

[0031] Working principle: First, the wire is placed in the through hole of the first hemisphere 1. Then, the slot mechanism 3 inside the second hemisphere 5 is connected to the block mechanism 2 inside the first hemisphere 1. The sliding block 22 is pressed into the first slot 32. When the sliding block 22 is pressed against the side wall of the limiting block 35, since the lower end of the sliding block 22 and the side wall of the limiting block 35 are curved, it is easy for the sliding block 22 to press against the limiting block 35. When the sliding block 22 presses against the limiting block 35, the limiting block 35 presses against the first spring 34. When the limiting block 35 is pressed into the second slot 33, the sliding block 22 enters the first slot. Inside 32, the limiting block 35 is flush with the third slot 23. Then, the first spring 34 pushes the limiting block 35 into the interior of the third slot 23. The limiting block 35 fixes the second fixing block 31 and the first fixing block 21 together. The wire passes through the through hole of the first hemisphere 1 and the second hemisphere 5. The wire squeezes the clamping block 45, and the clamping block 45 squeezes the second spring 44. The second spring 44 exerts a reaction force on the clamping block 45. The four clamping blocks 45 clamp the wire to prevent birds from flying into the interior of the first hemisphere 1 and the second hemisphere 5 through the through hole.
