Abstract
Description
Technical Field
[0001] This utility model relates to the field of bird-proofing equipment technology, specifically to a power grid bird-proofing device. Background Technology
[0002] Birds, as an important part of the food chain, play a vital role in the stability and protection of the ecological environment. However, the breeding of birds has a huge impact on power transmission lines. Every year, power transmission failures caused by birds nesting on power poles and playing on power lines occur frequently, seriously threatening my country's power supply security and being very detrimental to the improvement of people's living standards and industrial production.
[0003] Personnel carrying bird spikes climb the electric fence frame and install the spikes. They then need to pry the spikes apart one by one to create a scattered structure, thus completing the installation.
[0004] While the above equipment can install bird spikes on the electric fence, the work involves personnel working at heights. The spikes are arranged vertically, requiring them to be individually pried open, creating a scattered structure. This process is inconvenient and inefficient. While carrying the pried spikes themselves can speed up the installation, the spikes may tear clothing, causing further inconvenience. Utility Model Content
[0005] In view of this, the present invention provides a bird deterrent device for power grids. The present invention can avoid personnel having to pry open the bird deterrent spikes one by one, and at the same time improves the efficiency of personnel installing bird deterrent spikes.
[0006] To solve the above-mentioned technical problems, this utility model provides a power grid bird-proofing device, including a U-shaped base and multiple bird spikes. The tail ends of the bird spikes are provided with spheres. The upper surface of the U-shaped base is provided with a non-bending component, which includes a fixing post at the top of the U-shaped base. The fixing post has multiple spherical grooves, with the spheres located within the grooves. A fixing sleeve is fitted onto the fixing post, and the bird spikes are located inside the fixing sleeve. Specifically, personnel first install the U-shaped base on the L-shaped steel of the power grid frame. Then, by moving the fixing sleeve downwards, the fixing sleeve releases the restriction on the multiple bird spikes, indirectly causing the bird spikes to spread out on the fixing post. This avoids the need for personnel to pry the bird spikes apart one by one, and simultaneously improves the efficiency of installing the bird spikes.
[0007] The no-bend component also includes an external thread on the outer arc surface of the fixed column and an internal thread on the inner wall of the fixed sleeve. The external thread and the internal thread are threaded together; that is, by rotating the fixed sleeve on the fixed column, it is easy for the fixed sleeve to move up and down on the fixed column.
[0008] The bird deterrent spikes are equipped with bells at the tip; that is, the bells are installed on the bird deterrent spikes to facilitate the dispersal of birds.
[0009] The bottom of the U-shaped base is equipped with a magnetic piece; that is, the U-shaped base makes it easy for personnel to insert it into the L-steel on the electric grid frame, so that the magnetic piece is attracted to the L-steel, thus facilitating the installation of the U-shaped base.
[0010] The U-shaped base is equipped with two fixing bolts, which are located on one side of the fixing column; the use of two fixing bolts makes it convenient for personnel to install the U-shaped base on the power grid frame.
[0011] The U-shaped base, fixing post, and bird spikes are all made of stainless steel; this avoids rusting of the U-shaped base, fixing post, and bird spikes due to weather conditions.
[0012] The top of the fixed post is semi-circular, which facilitates the spreading out of multiple bird spikes.
[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0014] 1. When personnel carry bird spikes onto the power grid frame, the bird spikes are limited by the fixing sleeve, thus forming a clustered vertical state. Then, the personnel need to engage the internal thread on the fixing sleeve with the external thread on the fixing post, and rotate the fixing sleeve to move it downwards. The fixing sleeve releases the restriction on multiple bird spikes, thus exposing the fixing post. Then, because the ball at the bottom of the bird spike shakes on the top of the fixing post, it disperses, so the personnel do not need to pry the bird spikes apart one by one, improving the installation efficiency of bird spikes.
[0015] 2. The bird deterrent spikes are equipped with bells. Because the sphere at the bottom of the bird deterrent spikes can swing freely on the fixed post, the airflow blows towards the bird deterrent spikes, causing them to shake and carrying the bells. The bells disturb the birds, thereby reducing the time the birds stay in this area. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0024] like Figure 1-4 As shown: This embodiment provides a bird-proof device for electric grids, including a U-shaped base 100 and multiple bird spikes 103. The U-shaped base 100 is used for installation on the electric grid frame, and the bird spikes 103 can prevent birds from nesting in the area. The tail ends of the multiple bird spikes 103 are provided with spheres 205, which are fixedly installed on the tail ends of the bird spikes 103 by welding. The upper surface of the U-shaped base 100 is provided with a non-bending component 200, which includes a fixing post 203 provided on the top of the U-shaped base 100. The fixing post 203 is fixedly installed on the U-shaped base 100 by welding, thus providing support for the fixing post 203. The fixing post 203 is provided with multiple spherical grooves 204, and the spheres 205 are located in the spherical grooves 204. The spheres 205 are engaged within the spherical grooves 204, and can also be positioned within the spherical grooves 204. The fixed post 203 is rotated, and a fixed sleeve 201 is fitted on the fixed post 203. The bird spikes 103 are located inside the fixed sleeve 201. The fixed sleeve 201 can move up and down on the fixed post 203. When the fixed sleeve 201 moves to the top of the fixed post 203, the bottom of the bird spikes 103 is inside the fixed sleeve 201. The bird spikes 103 can gather inside the fixed sleeve 201 and avoid being scattered. This indirectly makes it easier for personnel to carry the bird spikes 103. Then, the fixed sleeve 201 moves down on the fixed post 203, so that the fixed post 203 is fully exposed. Since the balls 205 on the bottom of the multiple bird spikes 103 can rotate freely on the fixed post 203, the multiple bird spikes 103 are scattered. This avoids the need for personnel to pry the bird spikes 103 apart one by one and improves the efficiency of personnel installing the bird spikes 103.
[0025] No-break component 200 Figure 2 As shown,
[0026] The no-bending component 200 also includes an external thread 202 on the outer arc surface of the fixed column 203, and an internal thread 206 on the inner wall of the fixed sleeve 201. The external thread 202 and the internal thread 206 are threaded together. By rotating the fixed sleeve 201, the fixed sleeve 201 can move up and down on the fixed column 203, thereby speeding up the process of personnel scattering multiple bird spikes 103.
[0027] Bird spike protection 103 Figure 1 As shown,
[0028] The bird spike 103 is equipped with a bell 104 at its head. Since the ball 205 on the bottom of the bird spike 103 can swing freely on the fixed post 203, the airflow blows towards the bird spike 103, causing the bird spike 103 to swing and carry the bell 104 to swing. The bell 104 plays a role in disturbing the flock of birds, thereby reducing the time the flock of birds stays in this area.
[0029] A magnet 101 is provided at the bottom of the U-shaped base 100. The magnet 101 is fixedly installed on the U-shaped base 100. At the same time, a weak magnet is used so that when the U-shaped base 100 is installed on the power grid, it can be initially positioned, which facilitates subsequent installation by personnel.
[0030] The U-shaped base 100 is provided with two fixing bolts 102, which are located on one side of the fixing post 203. The use of fixing bolts 102 makes it convenient to install the U-shaped base 100 on the power grid.
[0031] The U-shaped base 100, the fixing post 203, and the bird spike 103 are all made of stainless steel, which can prevent the U-shaped base 100, the fixing post 203, the fixing post 203, and the bird spike 103 from rusting due to weather conditions.
[0032] Fixed column 203 Figure 2 As shown,
[0033] The top of the fixing post 203 is semi-circular, which makes it easy to spread out multiple bird spikes 103;
[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
