Description

Technical Field

[0001] This invention relates to the field of power grid facilities technology, and in particular to a bird spike-proof device that does not require breaking. Background Technology

[0002] In power grid systems, bird spikes are widely used to prevent birds from nesting or perching on the crossarms of transmission line towers, which could cause short circuits and other faults. Bird spikes mainly consist of a base fixedly connected to the crossarm and multiple spikes. The spread-out spikes form a physical barrier, preventing birds from approaching critical facilities.

[0003] However, existing bird spikes have significant drawbacks in practical use. After securing the base to the crossbeam, workers must bend each spike individually to create a spread-out protective structure. This bending process is cumbersome, time-consuming, and inefficient; especially in high-altitude work scenarios, it greatly prolongs the time workers are exposed to the hazardous environment, significantly increasing the risk of falls from heights. Furthermore, the spikes are sharp and easily injure workers during the bending process, posing a safety hazard.

[0004] Therefore, it is necessary to develop a bird spike-proof device that does not require breaking to address the aforementioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a bird spike that can be bent without bending, so as to solve the defects of existing bird spikes that are cumbersome, time-consuming, inefficient and have safety risks.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The bottom end of the support rod is provided with multiple locking slots spaced evenly at the top and bottom. One end of the locking connector is provided with locking teeth, which engage with the locking slots. The end of the locking connector away from the locking teeth is fixedly connected to the sliding rod mechanism, and the sliding rod mechanism is slidably connected to the cylinder cover.

Detailed Implementation

[0034] The core of this invention is to provide a bird spike that can be bent without bending, so as to solve the defects of existing bird spikes that are cumbersome, time-consuming, inefficient and have safety risks.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] In this invention, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", "link", "fix", "sleeve", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] In a specific embodiment of the present invention, a base 100 is included. The base 100 can be a component fixedly connected to the crossarm in the prior art or the form shown in the accompanying drawings, and can be selected according to actual needs. The base 100 shown in the accompanying drawings includes a hexagonal plate 110, a stud, and a nut. The stud is fixed to the bottom end of the hexagonal plate 110, and the nut is threaded onto the stud. In use, the hexagonal plate 110 is supported on the crossarm, the stud passes through the crossarm, and the nut is located on the side of the crossarm away from the hexagonal plate 110. The stud, the hexagonal plate 110, and the crossarm are fixed together by the nut. A flat washer and a spring washer can be provided between the nut and the crossarm.

[0039] The present invention also includes:

[0040] Support rod 200 is fixed to the top of base 100;

[0041] The cylindrical cover 300 is installed around the support rod 200.

[0042] Multiple needle-punching components 400 are arranged at intervals in the upper and lower parts, and the needle-punching components 400 are rotatably connected to the cylindrical cover 300;

[0043] Adjustment component 500 is fixed around the support rod 200, and adjustment component 500 and needle punch component 400 are set in a one-to-one correspondence and slidably connected;

[0044] The limiting component 600 is mounted on the sleeve 300 and detachably connected to the support rod 200.

[0045] In a specific embodiment of the present invention, the needle assembly 400 includes a plurality of forks 410 and a plurality of needles 420 corresponding to each fork 410. The needles 420 are welded or threaded to one end of the fork 410. The end of the fork 410 near the needle 420 is rotatably connected to the cylindrical cover 300 (specifically, the outer wall of the cylindrical cover 300 is provided with a lug corresponding to the fork 410, and the lug is rotatably connected to the fork 410 through a pin). The plurality of forks 410 are evenly distributed around the circumference. The end of the fork 410 away from the needle 420 extends into the inner cavity of the cylindrical cover 300, and the cylindrical cover 300 is provided with a clearance opening 310 for the fork 410 to swing, providing space for the fork 410 to swing and ensuring that the needle 420 can adjust its angle. When the adjusting component 500 and the sleeve 300 move up and down relative to each other, the shift fork 410 is acted upon by the adjusting component 500 and swings about the rotation connection point as an axis, thereby causing the needle 420 to spread out or retract.

[0046] In a specific embodiment of the present invention, the adjusting component 500 includes a ring 510 and connecting rods 520. The ring 510 is coaxially disposed around the support rod 200, and multiple connecting rods 520 are fixed between the ring 510 and the support rod 200. The ring 510 is slidably connected to the fork of the shift fork 410. Due to the slidable connection between the ring 510 and the fork of the shift fork 410, the shift fork 410 swings when the ring 510 and the shift fork 410 move relative to each other up and down, thereby adjusting the angle of the needle 420. Obviously, the connecting rods 520 need to be staggered with the shift fork 410 to prevent interference between them.

[0047] In a specific embodiment of the present invention, the limiting component 600 includes a sliding rod mechanism and a locking connector 610. The bottom end of the support rod 200 is provided with a plurality of locking slots 210 at even intervals. The locking slots 210 are annular structures. One end of the locking connector 610 is provided with a locking tooth 611, which engages with the locking slot 210. The end of the locking connector 610 away from the locking tooth 611 is fixedly connected to the sliding rod mechanism. The sliding rod mechanism is slidably connected to the cylindrical cover 300.

[0048] In a specific embodiment of the present invention, the slide bar mechanism includes a first moving rod 620, a second moving rod 630, and a compression spring 640. A snap-fit ​​connector 610 is fixedly connected to one end of the first moving rod 620, and the other end of the first moving rod 620 is fixedly connected to one end of the second moving rod 630. The other end of the second moving rod 630 slides through the cylindrical cover 300 and is fixedly connected to an operating component 650. The operating component 650 can be a pull ring or other component that facilitates finger application of force. The compression spring 640 is sleeved on the second moving rod 630 and is located between the first moving rod 620 and the cylindrical cover 300.

[0049] In one specific embodiment of the present invention, a guide tube 320 is fixed on the inner wall of the cylindrical cover 300, and a second moving rod 630 slides through the guide tube 320; one end of a compression spring 640 abuts against the end of the guide tube 320, and the other end of the compression spring 640 abuts against the end of the first moving rod 620. The guide tube 320 improves the support capacity of the cylindrical cover 300 for the second moving rod 630.

[0050] In a specific embodiment of the present invention, a sliding key is fixed to the inner wall of the guide tube 320, and a sliding groove is formed on the surface of the second moving rod 630, the sliding groove being slidably connected to the sliding key (not shown in the accompanying drawings). The sliding groove and the sliding key guide the first moving rod 620, preventing it from rotating arbitrarily during movement, and avoiding the locking connector 610 from being difficult to align and engage with the locking groove 210 after rotation.

[0051] In one specific embodiment of the present invention, at least one needle 420 is fixed to the top of the cylindrical cover 300. Since the needles 420 of the needle assembly 400 cannot cover the top of the cylindrical cover 300 after they spread out, the needles 420 fixed to the top of the cylindrical cover 300 can protect the top of the cylindrical cover 300, forming a more comprehensive bird-proof barrier.

[0052] In one specific embodiment of the present invention, the cylindrical cover 300 is a cylindrical shell structure or a shell structure that gradually tapers from bottom to top.

[0053] In a specific embodiment of the present invention, the cylindrical cover 300 is a shell structure that gradually decreases in size from bottom to top, and each step is provided with at least one needle-punching component 400.

[0054] The working principle of this invention for bird spike protection without bending is as follows: When the spike 420 needs to be unfolded, the operating component 650 is pulled, causing the second moving rod 630 to move the first moving rod 620 and the locking connector 610. The locking teeth 611 disengage from the locking groove 210. At this time, a downward force is continued to be applied to the operating component 650, causing the operating component 650 to move the second moving rod 630, the guide tube 320, the cylindrical cover 300, and the spike 420 downward. Since the ring body 510 does not move, the fork 410 can rotate around the connection point with the cylindrical cover 300, and the spike 420 unfolds to form a protective structure. Then, the operating component 650 is released, and under the action of the compression spring 640, the locking teeth 611 engage with the locking groove 210 of the support rod 200 near the base 100, completing the unfolding of the spike 420.

[0055] When it is necessary to retract the needle 420, pull the operating component 650, causing the second moving rod 630 to move the first moving rod 620 and the locking connector 610. The locking teeth 611 disengage from the locking groove 210. At this time, continue to apply an upward force to the operating component 650. The operating component 650 drives the second moving rod 630, the guide tube 320, the sleeve 300 and the needle 420 to move upward. Since the ring body 510 does not move, the shift fork 410 can rotate around the connection point with the sleeve 300, and the needle 420 retracts accordingly. Then release the operating component 650. Under the action of the compression spring 640, the locking teeth 611 engage with the locking groove 210 of the support rod 200 away from the base 100, completing the retraction of the needle 420.

[0056] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0057] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
