Description

Technical Field

[0001] The utility model relates to the technical field of bird-proofing equipment, in particular to a convenient bird-proofing nesting placeholder. Background Art

[0002] Birds nesting, moving, and defecating on transmission and distribution poles and crossarms can easily cause short circuits in the power system, and even lead to major power grid accidents. During the current installation of power distribution lines, double crossarms are commonly used at corner poles, reinforcement poles, tension poles, and other locations. However, birds often use double crossarms as nesting sites, building nests between the crossarms, posing a serious threat to the safe operation of distribution lines. To reduce the number of power system circuit breaker tripping incidents caused by bird activity, people have begun installing anti-bird nesting placeholders on transmission and distribution poles. The purpose of installing anti-bird nesting placeholders is to make birds think that the area is already occupied, thereby avoiding nesting there.

[0003] Existing bird nest prevention devices are of a fixed length. When the double crossarms are longer, the shorter bird prevention device cannot completely block the bird nest, allowing birds to continue nesting in areas not occupied by the bird nest prevention device. This results in poor flexibility and limited effectiveness in preventing bird nests. Furthermore, existing bird nest prevention devices typically require one worker to hold the device steady while another worker installs it using tools, making installation complex. Therefore, we propose a convenient bird nest prevention device. Utility Model Content

[0021] See also Figure 2 、 Figure 4 and Figure 5 In the figure, the guide mechanism includes a T-shaped slot 12 and a T-shaped block 16. The T-shaped block 16 is fixedly connected to the rear edge of the outer arc surface of the arc plate 2. The T-shaped slot 12 is opened at the top of the inner arc surface of the arc plate 1, and the T-shaped slot 12 and the T-shaped block 16 are slidably matched.

[0022] See also Figure 3In the figure, the elastic part includes an annular plate 14, which is fixedly mounted on the outer wall of the plug column 13, and one side wall of the annular plate 14 is in contact with one side wall of the inner side of the cylindrical tube 3, and a spring 15 is fixedly connected between the other side wall of the annular plate 14 and the other side wall of the inner side of the cylindrical tube 3, and the spring 15 is slidably mounted on the outer wall of the plug column 13.

[0023] See also Figure 1 and Figure 3 In the figure, the pulling member includes a pulling block 4, which is fixedly connected to the end of the plug column 13 away from the insertion hole 17, and the side wall of the pulling block 4 is in contact with the side wall of the cylindrical tube 3.

[0024] See also Figure 1 、 Figure 2 and Figure 4 In the figure, the auxiliary reinforcement component includes four tension springs 9, which are rotatably connected to the bottom ends of the four U-shaped plates 5 near the edge of the arc-shaped plate 1. The bottom ends of the two tension springs 9 on the same side are fixedly connected to a hook 10, and the bottom ends of the two tension springs 9 on the other side are fixedly connected to a ring 11.

[0025] See also Figure 1 and Figure 5 In the figure, the outer arc surfaces of the arc plate 1 and the arc plate 2 2 are embedded with multiple reflectors 7, and the multiple reflectors 7 are evenly distributed. Specifically, the reflectors 7 reflect sunlight to produce dazzling light, so the setting of multiple reflectors 7 can have the effect of repelling birds to a certain extent.

[0026] See also Figure 1 and Figure 5 In the figure, a toggle rod 8 is fixedly connected to the front edge of the outer arc surface of the arc-shaped plate 2; specifically, the setting of the toggle rod 8 facilitates the movement of the arc-shaped plate 2.

[0027] Working principle: During installation, first place the four U-shaped plates 5 on the arc plate 1 on the double cross arms on the telephone pole, and make the rear end of the arc plate 1 fit against the outer wall of the telephone pole, then use both hands to pull the two tension springs 9 in the front, so that the hook 10 on one of the tension springs 9 is hooked into the ring 11 on the other tension spring 9 (both tension springs 9 are located below the double cross arms). Similarly, according to the same operation, the hook 10 on the other tension spring 9 can be hooked into the corresponding ring 11 on the other tension spring 9. Then, the placeholder can be initially installed and fixed, which makes it convenient to insert and tighten the screws into the mounting holes 6 on the U-shaped plates 5 and insert and tighten them on the cross arms with the help of tools. There is no need for another staff member to hold the anti-bird nesting placeholder steady, which brings convenience to the staff's installation work.

[0028] When the length of the double cross arm is long, in order to achieve full occupation, the pull block 4 can be pulled first, and the pull block 4 will drive the plug post 13 to slide outward between the inner wall of the arc plate 1 and the cylindrical tube 3, and the plug post 13 will drive the annular plate 14 to slide in the cylindrical tube 3 (in this process, the spring 15 between the annular plate 14 and the cylindrical tube 3 will be squeezed on the outer wall of the plug post 13), and the plug post 13 will slide outward in the frontmost socket 17 on the arc plate 2 and completely slide out of the socket 17, and then, while keeping the pull block 4 pulled, the toggle rod 8 will be pulled forward, and the toggle rod 8 will The movable arc plate 2 2 slides forward on the arc plate 1 (in this process, the T-shaped block 16 on the arc plate 2 2 will slide forward in the T-shaped groove 12 on the arc plate 1) until the arc plate 2 2 moves to the required position (that is, the arc plate 2 2 and the arc plate 1 cooperate to achieve basically complete occupation of the double cross arm), and the pull block 4 can be released. Then, under the action of the spring 15, the plug post 13 will automatically reset and be inserted into another plug hole 17 on the corresponding arc plate 2 2. Then, the arc plate 2 2 can be kept fixed with the arc plate 1 again after moving, and the operation is simple.

[0029] It should be noted that the length of this anti-bird nesting placeholder is adjustable and can adapt to double crossarms of different lengths. It has good flexibility in use and good effect in preventing bird nesting. At the same time, under the action of the auxiliary reinforcement components, this anti-bird nesting placeholder does not require two workers to operate together when installing the anti-bird nesting placeholder, which brings convenience to the workers.
