Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of power transmission and transformation equipment maintenance, especially to a power transmission line bird nest removal tool. BACKGROUND

[0002] As the "Chinese Water Tower", Qinghai Province is rich in natural resources and has outstanding biodiversity. In recent years, with the sustained high pressure of environmental protection, the natural ecology in Qinghai has been further consolidated, and bird activity has shown an explosive growth trend. In order to better reproduce, birds usually choose to settle in prominent mountains or buildings. However, Qinghai Province is vast in area and lacks tall trees, so power transmission line towers become an ideal place for birds to nest. Currently, although bird prevention facilities such as bird prevention spikes, bird prevention needle plates, and bird repellents are installed on power transmission line towers, the nesting of birds on power transmission towers has not improved significantly. After nesting, birds frequently move in the power transmission line channel, which can easily cause line trip failures. According to incomplete statistics, from 2021 to 2024, the power transmission line towers under the jurisdiction of the Gonghe Operation and Maintenance Branch of Qinghai Ultra-High Voltage Company had a total of 486 bird nests, and the line failures caused by bird damage totaled 4 times. As can be seen from the above, it is urgent to remove the bird nests, which is crucial to improving the safety and stability of power transmission line operation.

[0003] The existing bird nest removal methods mainly rely on manual operation, using long poles, hooks and other tools to hook out or directly manually remove the bird nests. However, these methods have the following problems:

[0004] 1. Bird nests are usually located in high places or difficult-to-reach parts of power transmission towers, and operators need to climb or use aerial work equipment, increasing the difficulty and danger of operation. In addition, long-term aerial work can also cause fatigue, increasing the risk of accidents;

[0005] 2. The existing bird nest removal tools are mostly long poles or hook-shaped devices, which remove the bird nests by pushing them from one side. This method can easily cause the materials in the bird nests to fall on the conductors or in the surrounding environment, posing safety hazards such as electric shock and short circuit, and may threaten the stable operation of the power grid and the safety of the operators. INVENTION CONTENTS

[0006] To overcome the above technical problems, the utility model provides a power transmission line bird nest removal tool, which overcomes the difficulty of manual operation and the safety hazards in the bird nest removal process. The specific technical solution is as follows:

[0007] The utility model provides a kind of transmission line bird nest removal tool, which comprises a lead screw, one end of the lead screw is fixed with a lead screw handle for operating and controlling the movement of the lead screw. A sleeve is fitted on the lead screw, and the lead screw can slide in the sleeve along its axial direction. A pair of rakes is hinged to the end of the sleeve away from the lead screw handle, and the rakes are symmetrically arranged on both sides of the axis of the sleeve, so that the pair of rakes can open and close relative to each other for grasping and fixing the bird nest. To control the opening and closing of the rakes, the end of the lead screw away from the lead screw handle is connected to the inner side of the rakes on both sides by elastic ropes. When the operator pulls the lead screw, the pulling force exerted by the elastic ropes makes the rakes close, thereby firmly grasping the bird nest. In addition, the tool also comprises a screw fastener connected to the lead screw by screwing, which is located between the lead screw handle and the sleeve of the lead screw. By rotating the screw fastener, the operator moves it upwards along the lead screw until it contacts the bottom of the sleeve, achieving self-locking function to ensure that the rakes remain in the clamping state and will not loosen without external force. With this tool, the operator can safely and effectively remove the bird nest in high altitude or other difficult-to-reach places, avoiding the safety hazards caused by the scattering of bird nest materials in traditional methods, and improving work efficiency.

[0008] Further, the rakes comprise arc-shaped clamping members, and the outer side of the arc-shaped clamping members is provided with a plurality of sharp curved protrusions similar to nails or tines, which can enhance the grasping ability of the rakes, make them more firm when clamping the bird nest, and effectively grasp and fix the materials in the bird nest.

[0009] Further, the screw fastener is a long strip-shaped locking member, and a through hole is formed in the middle of the locking member, and the inner wall of the through hole is provided with an internal thread matched with the lead screw.

[0010] Further, the length of the sleeve is less than the length of the lead screw, ensuring that it can slide and position freely during operation.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] Through the linkage of the lead screw, elastic ropes and sleeve, the operator can safely and quickly remove the bird nest in high altitude or other difficult-to-reach places, effectively reducing the risk of high-altitude operation. The screw fastener automatically locks the rakes during operation, ensuring that they remain in the clamping state and will not loosen without external force, thereby avoiding the bird nest from sliding down during removal and ensuring the safety and stability of the operation.

[0013] In addition, by symmetrically opening and closing the rakes for grasping, the scattering of bird nest materials onto the conductor is prevented, reducing the risk of damage to power grid equipment due to short circuit or grounding fault. The utility model has simple structure and light weight, and is suitable for bird nest removal work in various environments, especially in narrow spaces and complex environments, improving work efficiency.
