Description

Technical Field

[0001] This invention relates to the field of power transmission line protection technology, specifically a device to prevent small animals from climbing power transmission lines. Background Technology

[0002] Most power transmission line towers are installed in outdoor areas using guyed installation, with one end buried underground and the other fixed to the top of the tower to ensure stability. In daily safe operation, due to the areas where the towers operate and the installation method, small animals frequently climb up the guy wires or directly onto the top of the towers, causing phase-to-phase short circuits or grounding faults in the power lines, resulting in power outages that affect power generation and user power consumption, causing significant power loss.

[0003] The losses caused by small animals climbing power lines are not limited to line outages; they can also include losses in electricity consumption and generation due to line maintenance and power outages, making it a serious safety hazard. Traditional "cone-shaped" anti-climb netting designs are ineffective because small animals can easily climb over them.

[0004] Chinese patent discloses a device for preventing small animals from climbing power transmission line towers (authorization announcement number CN213848440U). This patented technology can generate an electric shock effect the moment a small animal comes into contact with it, thus repelling it. However, electric shock alone may not be enough to dislodge the animal, as it still has a foothold. Therefore, this invention provides a device to prevent small animals from climbing power transmission line towers, in order to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a device to prevent small animals from climbing power transmission lines, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device to prevent small animals from climbing power transmission lines includes a power pole, a base mounted on the pole, and a top plate mounted on the upper side of the base. The base consists of two halves, which are fixed to the power pole by fixing lugs. The cross-section of the base perpendicular to the horizontal plane is T-shaped, forming an outer cover to prevent animals from climbing. Several protective plates are movably connected to the outer edge of the base. Each protective plate includes an arc-shaped plate, and a connecting rod is fixed to the lower side of the arc-shaped plate. The lower end of the connecting rod is slidably connected in a groove, which is fixed to the lower side of the base. A return spring is connected between the upper side of the arc-shaped plate and the base. Two permanent magnets are located above the return spring, respectively on the arc-shaped plate and the base, to position the arc-shaped plate. A solar panel is mounted on the top plate, which is electrically connected to a battery. The battery is electrically connected to a controller for control.

[0008] A movable rod is rotatably connected to the lower end of the base, and a driving block is slidably connected to the end of the movable rod.

[0012] Preferably, a ball is fixed to one end of the reset rod facing the guide plate, and the side of the guide plate facing the reset rod is arc-shaped to help the guide plate reset.

[0013] Preferably, the toothed ring has a notch for the movement of the intermediate rod.

[0014] Preferably, a guide post is fixed on the driving block, and the guide post is connected to the sliding groove of the moving rod by a spring, so that the driving block can move toward the utility pole when it is subjected to force.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see Figures 1-7 In this embodiment of the invention, the power transmission line anti-small animal pole climbing device includes a power pole 1, a base 2 installed on the power pole 1, and a top plate 3 installed on the upper side of the base 2. The base 2 is composed of two halves, which are fixed to the power pole 1 by fixing lugs 24. The cross-section of the base 2 perpendicular to the horizontal plane is T-shaped, forming an outer cover to prevent animals from climbing. Several protective plates 4 are movably connected to the outer edge of the base 2. The protective plates 4 include arc-shaped plates, and a connecting rod 5 is fixed to the lower side of the arc-shaped plates. The lower end of the connecting rod 5 is slidably connected in a groove 6, which is fixed to the lower side of the base 2. A return spring 41 is connected between the upper side of the plate and the base 2. A fixing rod is provided at the connection position between the return spring 41 and the base 2. The return spring 41 and the fixing rod are rotatably connected. The cross section of the arc plate perpendicular to the horizontal plane is teardrop-shaped. The upper end of the arc plate protrudes from the top plate 3 to protect it when it is pushed by an animal. Two permanent magnets 42 are provided above the return spring 41, located on the arc plate and the base 2 respectively, to position the arc plate. A solar panel is provided on the top plate 3. The solar panel is electrically connected to the battery 15. The battery 15 is electrically connected to the controller 14 for control.

[0035] A movable rod 7 is rotatably connected to the lower end of the base 2. A guide plate 21 is fixed to the upper side of the movable rod 7 at its rotation position. A reset rod 16 is provided on one side of the guide plate 21. The reset rod 16 is slidably connected inside the limiting cylinder 17. A ball is fixed to the end of the reset rod 16 facing the guide plate 21. The side of the guide plate 21 facing the reset rod 16 is arc-shaped to help the guide plate 21 reset. An intermediate rod 19 is rotatably connected to the end of the reset rod 16 away from the guide plate 21. The intermediate rod 19 is rotatably connected to a gear ring 18. The upper side of the gear ring 18 is connected to a motor 20 through a worm gear. The gear ring 18 has a notch for the intermediate rod 19 to move. A driving block 8 is slidably connected to the end of the movable rod 7. A guide post is fixed on the driving block 8. The guide post is connected to the sliding groove of the movable rod 7 through a spring, so that when the driving block 8 is subjected to force, it can move towards the utility pole 1. A locking interface 9 is provided on one side of the lever 1, and a pry bar 10 is locked onto the locking interface 9. The upper end of the pry bar 10 is rotatably connected to the base 2. A spring piece 11 is provided on the lower side of the pry bar 10 to help the pry bar 10 return to its original position. The lower end of the pry bar 10 extends out of the base 2. A ring-shaped conductive wire 13 is provided on the outer side of the driving block 8. The ring-shaped conductive wire 13 is connected to the battery 15 through a wire. Several conductive pieces are spaced apart on the lower end of the driving block 8. Several conductive pieces are embedded on the upper end of the arc-shaped protective plate 22. The conductive pieces are connected to the positive and negative terminals of the battery 15 respectively to electrically drive the animal on the lower side. A push switch is provided on one side of the pry bar 10. When the pry bar 10 drives the push switch to turn on, the battery 15 supplies power to the ring-shaped conductive wire 13 and the conductive pieces. An elastic ring 12 is sleeved on the outer side of the pry bar 10. When the animal comes up from one side, the elastic ring 12 is deformed by force, which in turn drives the pry bar 10 on the lower side to rotate.

[0036] The driving block 8 has a triangular cross-section and is inclined on the outside. The lower outer side of the base 2 is fitted with an interlocking arc-shaped protective plate 22. The inner side of the arc-shaped protective plate 22 is fixed with a claw, which engages with the slot 23 of the base 2 for fixation. The outer side of the arc-shaped protective plate 22 is a smooth curved surface. The lower end of the pry bar 10 is inclined outward and the outer side of the lower end of the pry bar 10 is flush with the outer side of the arc-shaped protective plate 22.

[0037] The working principle of this invention is as follows: When in use, it is installed by fixing ears 24 on the base 2, the base 2 is fixed on the utility pole 1, and then the top plate 3 is installed. The arc-shaped protective plate 22 is fixed by the slot 23 to complete the installation.

[0038] When an animal climbs the pole, the first step is to block it through the arc-shaped protective plate 22. The smooth outer surface hinders the animal's ascent. After the animal crosses the arc-shaped protective plate 22, when the point of force is on the pry bar 10, the pry bar 10 is stressed, the spring piece 11 is compressed, the pry bar 10 disengages from the locking interface 9, and the moving rod 7 and the driving block 8 are unlocked. At the same time, pressing the switch turns on the circuit, supplying power to the annular conductive wire 13 and the conductive sheet. The driving block 8 falls under the influence of gravity, driving the animal outward. Meanwhile, the energized position on the outside allows the animal to detach from the fixed position. The upper conductive sheet of the arc-shaped protective plate 22 is connected to the power supply. When the animal comes into contact with it, the current is conducted, so that the animal has no point of force and reaches the driving position. When the point of force is on the driving block 8, the lower end of the driving block 8 drives the pry bar 10 to rotate, achieving the same effect.

[0039] When the animal touches the protective plate 4, the permanent magnet 42 of the protective plate 4 disengages, and the protective plate 4 rotates and slides downward along the slide groove 6, thereby changing the force position of the animal, making the animal's grip unstable. When the force is no longer applied, the return spring 41 drives the protective plate 4 to return to its original position, and the permanent magnet 42 is positioned.

[0040] According to the monitoring of the controller 14, when the push switch is turned on, the controller 14 controls the motor 20 to start after a period of time. The motor 20 drives the gear ring 18 to rotate through the worm gear, which in turn drives the reset rod 16 to move through the intermediate rod 19. The reset rod 16 pushes the guide plate 21, which in turn drives the moving rod 7 and the driving block 8 back to the initial position. They are then fixed by the pry bar 10 and the locking interface 9, and restored to the initial position.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
