Description

Technical Field

[0001] This utility model relates to the field of bird deterrent technology, and in particular to a bird deterrent for power transmission lines. Background Technology

[0002] A bird deterrent is a device used to prevent birds from approaching a specific area. Its main purpose is to prevent bird activity from causing harm to the power system, ensuring the safe and stable operation of the power grid, and at the same time protecting birds from harm.

[0003] The bird deterrent device mainly consists of a physical support and a rotating bird deterrent component. It achieves the bird deterrent effect by combining visual and physical barriers. The support is fixed to facilities such as power transmission lines. It uses wind power to drive a rotating windmill, and the ribbons or whistles on the windmill make sounds to scare away birds. At the same time, the physical structure directly prevents birds from landing.

[0004] Bird deterrents for power transmission lines are typically installed on utility poles or high-voltage towers, resulting in their long-term exposure to the outdoors. When faced with the threat of storms and extreme weather, traditional wind-driven rotary bird deterrents generally have wind resistance defects. Strong winds drive the rotary bird deterrent components to operate at excessive speeds, often exceeding 300 r / min, which can cause the blades to break or even disintegrate completely. The resulting debris seriously threatens the insulation safety of the power transmission lines. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing transmission bird deterrents are difficult to cope with extreme weather conditions such as storms, and to propose a bird deterrent for power transmission lines.

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

[0007] A bird deterrent device for power transmission lines includes a mounting frame detachably connected to a power tower. A bird deterrent assembly is provided on the top of the mounting frame. The bird deterrent assembly includes a rotating base rotatably connected to the top of the mounting frame, a hemispherical cover fixedly connected to the rotating base, and a reflector fixedly connected to the open end of the hemispherical cover, a friction block slidably connected inside the rotating base, one side of the friction block being in contact with the circumferential surface of the mounting frame, and a force-applying arm rotatably connected to the rotating base. One end of the force-applying arm abuts against the friction block, and the other end of the force-applying arm is provided with a counterweight. When the rotation speed of the rotating base exceeds a preset value, the force-applying arm rotates and pushes the friction block to press against the mounting frame.

[0008] To facilitate the operation of the lever arm, preferably, a counterweight is fixedly installed at the end of the lever arm. When the rotating base rotates, the counterweight rises due to centrifugal force, causing the lever arm to rotate along the axis of the rotating shaft.

[0009] To facilitate the use of centrifugal force to lift the lever arm, the lever arm is further divided into a power arm and a resistance arm with the axis of the rotating shaft as the center. The length ratio of the resistance arm to the power arm is 1:5. When the counterweight rises, the power arm rotates along the rotating shaft after being subjected to force, causing the end of the resistance arm to move down, so that the resistance arm pushes the friction block to squeeze the mounting frame.

[0010] To facilitate the repositioning of the friction block, preferably, a groove is provided in the rotating base, and a support rod is slidably installed in the groove. The end of the support rod extends to the outside of the groove and is fixedly installed with the friction block. A spring is sleeved on the support rod, and the two ends of the spring abut against the support rod and the groove, respectively. When the thrust of the applied arm decreases, the spring rebounds and pushes the support rod to move, thereby repositioning the friction block.

[0011] To prevent the friction block from moving too much, the support rod is further configured as a "T" shape, and the diameter of the protrusion of the support rod is the same as the diameter of the groove.

[0012] To reduce the impact of strong winds on the hemispherical cover, preferably, a mounting plate is fixedly connected to the hemispherical cover, the mounting plate has an air inlet hole, and the hemispherical cover has an air outlet hole, with the air inlet hole and the air outlet hole being connected.

[0013] Compared with the prior art, this utility model provides a bird deterrent for power transmission lines, which has the following beneficial effects:

[0014] 1. This bird deterrent for power transmission lines uses a lever arm in conjunction with a friction block. When encountering stormy weather, causing the hemispherical cover to rotate at a speed exceeding 300 r / min, the lever arm, due to centrifugal force, pushes the friction block against the mounting frame through the resistance arm, thereby increasing friction and reducing the rotational speed of the rotating base. This effectively prevents the hemispherical cover from breaking or the bird deterrent from disintegrating due to storms, thus avoiding the danger to the insulation safety of power transmission lines caused by fragments from disintegration.

[0015] 2. The bird deterrent device for power transmission lines uses a combination of an air outlet and an air inlet on a hemispherical cover and a mounting plate. In the event of a storm, the air inlet and outlet can reduce the rotation speed of the hemispherical cover, thereby preventing the bird deterrent device from disintegrating due to excessive rotation speed of the rotating base, thus effectively improving the practical effect of this application.

[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model uses a force-applying arm in conjunction with a friction block, which enables the application to achieve a passive deceleration effect under storm conditions. By squeezing the support rod with the friction block, the rotation speed of the rotating base is reduced, effectively preventing the hemispherical cover from breaking or the bird deterrent from disintegrating, and preventing the fragments after disintegration from threatening the insulation safety of the transmission line.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0024] Reference Figures 1-4A bird deterrent for power transmission lines includes a mounting frame 1 detachably connected to a power tower. A bird deterrent assembly is provided on the top of the mounting frame 1. The bird deterrent assembly includes a rotating base 2 rotatably connected to the top of the mounting frame 1, a hemispherical cover 3 fixedly connected to the rotating base 2, and a reflector 4 fixedly connected to the open end of the hemispherical cover 3, a friction block 5 slidably connected inside the rotating base 2, one side of the friction block 5 being in contact with the circumferential surface of the mounting frame 1, and a force-applying arm 6 rotatably connected to the rotating base 2. One end of the force-applying arm 6 abuts against the friction block 5, and the other end of the force-applying arm 6 is provided with a counterweight. When the rotation speed of the rotating base 2 exceeds a preset value, the force-applying arm 6 rotates and pushes the friction block 5 to press against the mounting frame 1, thereby reducing the rotation speed of the rotating base 2 and avoiding the problem of the hemispherical cover 3 breaking or the bird deterrent disintegrating due to the excessive rotation speed of the rotating base 2.

[0025] Specifically, by using the force-applying arm 6 in conjunction with the friction block 5, when encountering stormy weather that causes the hemispherical cover 3 to drive the rotating base 2 to rotate at a speed exceeding 300 r / min, the force-applying arm 6, due to centrifugal force, pushes the friction block 5 to squeeze the mounting frame 1 through the resistance arm, thereby increasing the friction force and reducing the rotation speed of the rotating base 2. This effectively prevents the hemispherical cover 3 from breaking or the bird deterrent device from disintegrating due to storms, thus avoiding the problem of fragments from disintegration endangering the insulation safety of power transmission lines.

[0026] A counterweight 7 is fixedly installed at the end of the force-applying arm 6. When the rotating base 2 rotates, the counterweight 7 rises due to centrifugal force, causing the force-applying arm 6 to rotate along the axis of the rotating shaft. The counterweight 7 further enhances the application effect of centrifugal force, so that when the rotating base 2 rotates more than 300 r / min, the counterweight 7 pushes the force-applying arm 6 to work, thereby causing the force-applying arm 6 to push the friction block 5 and squeeze the positioning rod, thus facilitating the reduction of the rotation speed of the rotating base 2.

[0027] The force-applying arm 6 is divided into a power arm and a resistance arm with the axis of rotation as the center. The length ratio of the resistance arm to the power arm is 1:5. When the counterweight 7 rises, the power arm rotates along the axis after being subjected to force, causing the end of the resistance arm to move down. This causes the resistance arm to push the friction block 5 to press against the mounting frame 1. The longer power arm allows the resistance arm to push the friction block 5 more easily when the force-applying arm 6 is working, increasing the pressure of the friction block 5 on the top of the mounting frame 1, thereby facilitating the reduction of the rotation speed of the rotating base 2.

[0028] The rotating base 2 has a groove, and a support rod 8 is slidably installed in the groove. The end of the support rod 8 extends to the outside of the groove and is fixedly installed with the friction block 5. A spring 9 is sleeved on the support rod 8. The two ends of the spring 9 abut against the support rod 8 and the groove, respectively. When the thrust of the force arm 6 decreases, the spring 9 rebounds and pushes the support rod 8 to move, so that the friction block 5 is reset. This effectively avoids the situation where the friction block 5 is difficult to reset after working, which would prevent the application from being used normally in a light wind.

[0029] The support rod 8 is set in a "T" shape, and the diameter of the protrusion of the support rod 8 is the same as the diameter of the groove. The protrusion of the support rod 8 away from the friction block 5 avoids the problem that the spring 9 pushes the friction block 5 a long distance when it resets. On the other hand, it can also avoid the problem that the friction block 5 wears some material after long-term use, which would make it difficult for the force arm 6 to contact the friction block 5.

[0030] A mounting plate 10 is fixedly connected to the hemispherical cover 3. An air inlet 11 is provided on the mounting plate 10, and an air outlet 12 is provided on the hemispherical cover 3. The air inlet 11 and the air outlet 12 are connected. By using the air outlet and air inlet provided on the hemispherical cover 3 and the mounting plate 10 in conjunction, when encountering stormy weather, the air inlet and air outlet can reduce the rotation speed of the hemispherical cover, thereby avoiding the situation where the bird deterrent device disintegrates due to excessive rotation speed of the rotating base 2, and effectively improving the practical effect of this application.

[0031] In this invention, when the bird deterrent device encounters a storm, the hemispherical cover 3 is affected by the storm and causes the rotating base 2 to rotate at high speed. The centrifugal force generated by the rotating base 2 throws the counterweight 7 up, and the force arm 6 moves with the counterweight 7, thereby causing the force arm 6 to rotate along the axis of the rotating shaft. When the force arm 6 rotates, it pushes the friction block 5 to move, and then the friction block 5 presses against the top of the mounting frame 1, thereby reducing the rotation speed of the rotating base 2. This effectively avoids the problem of the hemispherical cover 3 breaking or the bird deterrent device disintegrating due to the high speed of the rotating base 2, and prevents the fragments generated by the disintegration from threatening the insulation safety of the transmission line.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
