[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0027] Example 1

[0028] Reference Figures 1 and 2 , which is the first embodiment of the present invention, provides a tower anti-snake and rat climbing device. Through the mutual cooperation between the installation unit 100, the adjustment unit 200 and the warning unit 300, the problem of line tripping after short circuit caused by snakes and rats climbing up the tower to the top of the equipment or the line body to cause damage is solved, thereby achieving the beneficial effect of protecting the equipment or lines on the tower. Specifically, it includes the installation unit 100, which provides a basis for the installation of the tower anti-snake and rat climbing device, and includes a steel ring assembly 101 and a locking assembly 102. The steel ring assembly 101 is mounted on the tower through the locking assembly 102, wherein the tower is a circular support rod for photovoltaics, and the locking assembly 102 is used to fix the steel ring assembly 101 on the tower; the adjustment unit 200 provides the function of preventing snakes and rats from climbing, and includes a moving assembly 201 arranged outside the steel ring assembly 101 and a locking assembly 102 connected to the tower. The moving component 201 is rotatably connected to the spike component 202. The moving component 201 provides a basis for recovering the spikes during maintenance to prevent accidental injury to maintenance personnel. The spike component 202 plays a role in preventing snakes and rats from climbing. The warning unit 300 uses impact sound to warn snakes and rats, thereby achieving an anti-climbing effect. It includes a trigger component 301 set on the moving component 201, and a clicker component 302 connected to the lever of the trigger component 301. The trigger component 301 is subjected to external force, which provides a basis for the sound impact of the clicker component 302.

[0029] Furthermore, the steel ring assembly 101 is a stainless steel ring, including a first steel ring 101a, a second steel ring 101b arranged at one end of the first steel ring 101a, a shrinkage groove 101c arranged between the first steel ring 101a and the second steel ring 101b; and several groups of limiting grooves 101d are arranged on the outside of the first steel ring 101a and the second steel ring 101b; an installation space M is formed between the first steel ring 101a and the second steel ring 101b, providing space for the first steel ring 101a and the second steel ring 101b to be installed on the tower pole.

[0030] Furthermore, the locking assembly 102 is a connector for securing the steel ring assembly 101. It includes a locking buckle 102a fixedly connected to the outer sidewall of the first steel ring 101a, and a locking block 102b engaged with the locking buckle 102a. The locking block 102b is fixedly connected to the second steel ring 101b. The first and second steel rings 101a, 101b are secured to the tower by the engagement of the locking buckle 102a and the locking block 102b.

[0031] It should be noted that two sets of locking buckles 102a are respectively provided at both ends of the first steel ring 101a. Similarly, two sets of locking blocks 102b are respectively provided at both ends of the second steel ring 101b, which are adapted to the locking buckles 102a.

[0032] When in use, the locking buckle 102a has an outward-expanding tail on both sides and is arc-shaped. During installation, the first steel ring 101a and the second steel ring 101b are placed on both sides of the tower to be installed and external force is applied. The outward-expanding tail of the locking buckle 102a shrinks inward due to the compression of the installation space on the locking block 102b. At this time, the arc surface of the tail of the locking buckle 102a makes it easier for the locking buckle 102a to pass through the locking block 102b. When the locking buckle 102a completely passes through the installation space on the locking block 102b, the tail of the locking buckle 102a expands outward again due to the release of compression, completing the fastening. From then on, the first steel ring 101a and the second steel ring 101b are installed. At this time, the arc of the tail of the locking buckle 102a opens outward again, reinforcing the connection between the first steel ring 101a and the second steel ring 101b. This time, four sets of clips are set at the same time. Even if one set of clips fails for some reason, the other three sets of clips can still maintain the stability of the connection.

[0033] In summary, the beneficial effect of a tower snake and rat climbing prevention device is that the locking assembly enables installation and removal, improving mobility and ease of maintenance. The spike assembly design not only effectively prevents snakes and rats from climbing, enhancing protection performance; the recyclable spikes also simplify maintenance procedures, reduce maintenance costs, and make repairs easier. In addition, by pulling the trigger assembly, the clicker assembly produces a sound during the pulling process, which to some extent repel snakes and rats from climbing upwards, further enhancing protection performance.

[0034] Example 2

[0035] Reference Figures 3 to 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a tower snake and rat climbing prevention device. Through the mutual cooperation of the moving component 201 and the spike component 202, it solves the problem of line tripping after short circuit caused by snakes and rats climbing along the tower to the top of the equipment or the line body to cause damage, thereby achieving the beneficial effect of protecting the equipment or lines on the tower; the design of recyclable spikes also simplifies the maintenance process, reduces maintenance costs, and makes maintenance easier. Specifically, it includes a moving component 201, which provides a basis for the recyclability of the spikes, including a moving ring 201a, several groups of support shafts 201b fixedly connected to the bottom of the moving ring 201a, a moving block 201c fixedly connected to the top of the moving ring 201a, a fixed block 201d bolted to the moving block 201c, a moving limit column 201e fixedly connected to the support shaft 201b, a protruding shaft 201f fixedly connected to both ends of the support shaft 201b, and a protruding shaft 201f rotatably connected to the protruding shaft 201f. The following components comprise a driven moving rod 201g, a protruding end 201h disposed at the bottom of the driven moving rod 201g, a fixed plate 201i slidably connected to the protruding end 201h, fixed slots 201j symmetrically disposed on either side of the fixed plate 201i, a positioning post 201k fixedly connected to the top of the fixed plate 201i, first and second telescopic slots 201l and 201m symmetrically disposed on either side of the positioning post 201k and located on the surface of the fixed plate 201i, and two sets of weight-reducing holes 201n symmetrically disposed on either side of the surface of the fixed plate 201i. There are two sets of moving rings 201a, with the bottom support shafts 201b uniformly distributed at the bottom of the moving rings 201a.

[0036] Furthermore, spike assembly 202 is equipped with spike protection on its surface and sides to prevent climbing. It includes two sets of sleeves 202a symmetrically arranged at both ends of support shaft 201b, T-shaped connecting rods 202b fixedly connected to the outer walls of sleeves 202a, a spike mounting plate 202c plugged into T-shaped connecting rods 202b, and several sets of spikes 202d fixedly connected to the upper and lower surfaces and side walls of spike mounting plate 202c. To facilitate installation, spike mounting plate 202c has an extension near locking buckle 102a.

[0037] Furthermore, the movable limiting column 201e is fixedly connected to the side of the support shaft 201b close to the first steel ring 101a, the movable limiting column 201e is slidingly connected to the limiting groove 101d, and the movable limiting column 201e and the support shaft 201b are set to the same group number.

[0038] Furthermore, the protruding end 201h is adapted to the fixing groove 201j, and the protruding end 201h is slidably connected to the fixing plate 201i through the fixing groove 201j.

[0039] Furthermore, the two sets of sleeves 202a are rotatably connected to the support shaft 201b, and the inner wall of the spike mounting plate 202c is provided with a T-shaped plug slot. The length of the spike mounting plate 202c is greater than the length of the support shaft 201b and both ends extend to the top of the two sets of driven moving rods 201g.

[0040] It should be noted that when the spike assembly 202 is stable in a horizontal position, the spike mounting plate 202c is supported by the driven moving rod 201g in a non-vertical state. At this time, the driven moving rod 201g and the spike mounting plate 202c maintain a fixed angle α. When the protruding end 201h at the bottom of the driven moving rod 201g slides in the fixed groove 201j on the side of the fixed plate 201i, the driven moving rod 201g rotates from the non-vertical state to the vertical state, and the spike mounting plate 202c loses the support of the driven moving rod 201g. At this time, in order to maintain the fixed angle α with the driven moving rod 201g, the sleeve 202a starts to rotate and move, so that the spike mounting plate 202c and the driven moving rod 201g maintain a fixed angle α.

[0041] During use, the limiting column 201e is moved upward in the limiting groove 101d to the fixed block 201d and fixed. At this time, the sleeve 202a starts to rotate during the movement of the driven moving rod 201g, and the spike mounting plate 202c always maintains a fixed angle α with the moving rod 201g. When the driven moving rod 201g rotates and moves to a vertical state, the spike mounting plate 202c is recovered.

[0042] In summary, the beneficial effect of a pole tower anti-snake and rat climbing device is that through the setting of several groups of spikes, obstacles will appear in the climbing process of snakes and rats, thereby achieving anti-snake and rat climbing and enhancing the protection performance; during the movement of the moving ring, the rotational motion trajectory of the spike mounting plate is realized through the motion trajectory of the driven moving rod, thereby achieving effective recovery of the spikes, simplifying the maintenance process, reducing maintenance costs, and making maintenance easier.

[0043] Example 3

[0044] Reference Figure 7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a tower snake and rat climbing prevention device. Through the cooperation of the trigger assembly 301 and the clicker assembly 302, different components collide to produce a sound, thereby achieving the beneficial effect of preventing snakes and rats from climbing. Specifically, it includes a trigger assembly 301. The configuration of the trigger assembly 301 converts the external force it receives into an interaction force between the components, providing a basis for warning snakes and rats from climbing. It includes a balancing shaft 301a, a reversing shaft 301b rotatably connected to the end of the balancing shaft 301a near the first telescopic slot 201l and away from the second telescopic slot 201m, a same-direction shaft 301c rotatably connected to the end of the reversing shaft 301b away from the first telescopic slot 201l, and a touch plate 301d rotatably connected to the end of the same-direction shaft 301c away from the first telescopic slot 201l. The middle portion of the balancing shaft 301a is rotatably connected to the fixed plate 201i.

[0045] Furthermore, the clicker assembly 302 moves in position through the force converted by the trigger assembly 301, resulting in an impact with a fixed position, thereby making a sound to warn snakes and rats, thereby achieving an anti-climbing effect. It includes a counterweight shaft 302a that is rotatably connected to one end of the balance shaft 301a away from the first telescopic slot 201l and close to the second telescopic slot 201m, and a warning sheet 302b that is bolted to the threaded hole at the bottom of the counterweight shaft 302a.

[0046] It should be noted that, in order to ensure that the trigger assembly can be triggered normally, the total mass of the counterweight shaft 302a and the warning sheet 302b is slightly heavier than that of the touch panel 301d and the reversing shaft 301b.

[0047] During use, when the touch panel 301d receives an external force, it shifts position. The end of the reversing shaft 301b, which is rotatably connected to the touch panel 301d, experiences a downward pull, causing it to move downward. Simultaneously, the end of the balancing shaft 301a, which is closer to the first telescopic slot 201l and farther from the second telescopic slot 201m, experiences a pull, causing it to move downward. Simultaneously, the balancing shaft 301a loses its balance, triggering the trigger assembly 301. At this point, the end of the balancing shaft 301a, which is farther from the first telescopic slot 201 and closer to the second telescopic slot 201m, experiences an equal upward pull, causing the counterweight shaft 302a to move upward. Simultaneously, the warning sheet 302b, which is fixedly connected to the counterweight shaft 302a, moves upward, colliding with the bottom of the fixed plate 201i, producing a loud noise that serves as a warning to snakes and rats, thereby preventing them from climbing.

[0048] In summary, the beneficial effect of a tower anti-snake and rat climbing device is that through the cooperation of the touch plate and the balance shaft, the clicker and the fixed plate collide to produce a sound, which to a certain extent repel snakes and rats from climbing upwards and further enhance the protection performance.
