Description

Technical Field

[0001] The utility model relates to the technical field of power grid facilities, in particular to a needle-type bird deterrent thorn. Background Art

[0002] Bird deterrent thorns are usually installed on power transmission towers, and multiple needles are radially opened to prevent birds from building nests.

[0003] Traditional bird deterrent thorns have certain defects. They are usually fixedly installed and the bird deterrent effect is average. If the opening degree of the needles is too small, the protection range is small, leaving too much space around the cross arm, and some small birds can still build nests. If the opening degree of the needles is too large, the distance between the tips of the needles is large. After a period of time, the birds will get used to it and will have the courage to stay on the needles and even build nests based on multiple needles as the basic framework.

[0004] For example, the patent with the publication number CN217160907U discloses a bird deterrent thorn that is firmly fixed and not prone to loosening. However, it has the following problems: if the opening degree of the needles is too small, the protection range is small, leaving too much space around the cross arm, and some small birds can still build nests. If the opening degree of the needles is too large, the distance between the tips of the needles is large. After a period of time, the birds will get used to it and will have the courage to stay on the needles and even build nests based on multiple needles as the basic framework;

[0005] Its specification also records that "mainly considering that birds may occasionally perch on the thorn rods. When a bird perches on the thorn rod, it will squeeze the hemispheres, and then squeeze the elastic members, causing the hemispheres to shake up and down, so as to easily startle the birds, and finally make the birds quickly leave the iron tower, further reducing the occurrence of bird damage accidents." However, in actual application, due to the large number of thorn rods, the mutual extrusion between the thorn rods and the cluster tube, and the generally small body weight of the birds, even if the birds perch on the thorn rods, it is very difficult to make the hemispheres shake, and the birds cannot be effectively startled.

[0006] Therefore, it is necessary to develop a needle-type bird deterrent thorn to address the above defects. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a needle-type bird deterrent thorn that can improve the bird deterrent effect of the bird deterrent thorn.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0030] In a specific embodiment of the present utility model, as Figures 1 to 3 shown, it includes a thorn base 1, and a plurality of thorns 2 are fixed to the top end of the thorn base 1. The thorns 2 are radially spread out. It also includes a bottom plate 3, a sleeve 4 and a rotating shaft 5. The bottom end of the sleeve 4 is fixedly connected to the top surface of the bottom plate 3. The bottom end of the rotating shaft 5 is rotatably connected to the sleeve 4. One side of the top end of the rotating shaft 5 is horizontally fixedly connected with an adjusting rod 6. The thorn base 1 is slidably matched with the adjusting rod 6. A positioning component for positioning the thorn base 1 is arranged on the adjusting rod 6;

[0031] A wind bowl assembly is fixed on the part of the rotating shaft 5 between the sleeve 4 and the adjusting rod 6. A plurality of wind bowl assemblies are circumferentially and evenly distributed with the axis of rotation of the rotating shaft 5 as the center. A sounding component is arranged on the wind bowl assembly;

[0032] One side of the top end of the rotating shaft 5 is fixedly connected with a counterweight 7, and the counterweight 7 is located on the side of the rotating shaft 5 away from the adjusting rod 6.

[0033] Specifically, the wind blows the wind bowl assembly, the wind bowl assembly drives the rotation of the rotating shaft 5, the rotating shaft 5 drives the adjusting rod 6 to rotate around the axis of rotation of the rotating shaft 5, the adjusting rod 6 drives the thorn seat 1 to synchronously rotate around the axis of rotation of the rotating shaft 5, and the thorn seat 1 drives the acupuncture needles 2 to move synchronously. Therefore, the birds can be actively driven and disturbed. Thus, regardless of the opening degree of the acupuncture needles 2, the birds cannot build nests on the acupuncture needles 2, improving the bird prevention effect.

[0034] By adjusting the position of the thorn seat 1 on the adjusting rod 6, the protection range when the acupuncture needles 2 move synchronously with the thorn seat 1 can be adjusted. The farther the thorn seat 1 is from the rotating shaft 5, the larger the protection range. During actual installation, it should be noted that there should be no other objects such as wires and insulators within the protection range of the acupuncture needles 2.

[0035] The sound - generating component can disturb the birds, improving the bird prevention effect.

[0036] The counterweight 7 mainly plays a role in balancing and stabilizing. Since the adjusting rod 6, the acupuncture needles 2, and the thorn seat 1 are eccentric to the axis of rotation of the rotating shaft 5, the force on the rotating shaft 5 is unbalanced when it rotates. Therefore, the counterweight 7 can offset a part of the unbalanced force, making the rotation of the rotating shaft 5 stable.

[0038] Specifically, loosen the first bolt 8 to make the thorn seat 1 slide in the chute, thereby adjusting the position of the thorn seat 1 on the adjusting rod 6. After adjustment, tighten the first bolt 8.

[0039] There are at least three wind bowl assemblies. The wind bowl assembly includes a bowl shell 9 and a connecting rod 10. The connecting rod 10 is horizontally arranged. One end of the connecting rod 10 is fixedly connected to the rotating shaft 5, and the other end of the connecting rod 10 is fixedly connected to the bottom wall of the bowl shell 9. The open end of the bowl shell 9 faces one side, and the central axis of the bowl shell 9 is perpendicular to the central axis of the connecting rod 10.

[0040] Specifically, the bowl shell 9 receives the wind air flow, so that the bowl shell 9 drives the connecting rod 10 to act, and the connecting rod 10 drives the rotating shaft 5 to rotate. The connecting rod 10 is threadedly connected or welded to the rotating shaft 5.

[0041] The sound - generating component is a whistle 11. The air inlet end of the whistle 11 is fixedly connected to the connecting rod 10. The whistle 11 is coaxially arranged with the bowl shell 9, and the inner cavity of the bowl shell 9 is communicated with the air inlet end of the whistle 11.

[0042] Specifically, the wind air flow received by the bowl shell 9 enters the whistle 11, and then the whistle 11 emits a sound.
