DETAILED DESCRIPTION

[0027] The embodiment of the present application discloses an anti-climbing power tower, which is achieved by adding an extended support rod 11 to the support leg of the tower body 1, installing a protective device 2 on the support rod 11, and implementing three-level protection of the tower body 1 through the first anti-climbing mechanism 3, the second anti-climbing mechanism 4 and the third anti-climbing mechanism 5 installed on the protective device 2, thereby reducing the possibility of people or animals climbing onto the tower body 1, greatly improving the protection of the tower body 1, solving the problem of poor protection effect of the power tower in the prior art, and effectively improving the protection performance of the power tower and improving the anti-climbing effect.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1 , Figure 2 and Figure 3 An anti-climbing power tower includes a plurality of support rods 11 fixedly installed below a tower body 1. The extension direction of the support rods 11 is consistent with the extension mode of the legs of the tower body 1. The upper ends of the support rods 11 are fixedly connected to the corresponding legs, and the lower ends of the support rods 11 are buried in the ground, which can support the entire tower body 1. A protective device 2 is installed on the support rods 11 to prevent people or animals from climbing onto the tower body 1 to avoid danger or damage to the tower body 1. The protective device 2 includes a first anti-climbing mechanism 3, a second anti-climbing mechanism 4 and a third anti-climbing mechanism 5 which are sequentially arranged from bottom to top along the height direction of the support rods 11. The first anti-climbing mechanism 3 can reduce small creatures such as reptiles from climbing onto the tower body 1 along the support rods 11, the second anti-climbing mechanism 4 can reduce small animals from climbing onto the tower body 1, and the third anti-climbing mechanism 5 can greatly reduce people or large animals from climbing. The three-level protection is arranged on the support rods 11, which can effectively improve the protection performance of the tower body 1.

[0030] Reference Figure 3The first anti-climbing mechanism 3 includes a first protective cover 31 and an insecticidal lamp 32. The first protective cover 31 is sleeved outside the support rod 11 and is close to the lower end of the support rod 11. The outer diameter of the first protective cover 31 increases from top to bottom, and the upper surface of the first protective cover 31 is smooth. A plurality of insecticidal lamps 32 are provided and fixedly bonded to the lower end surface of the first protective cover 31. The insecticidal lamps 32 are used to reduce crawling insects and other small insects from climbing up the tower body 1 along the support rod 11.

[0031] Reference Figure 3 , Figure 4 The second anti-climbing mechanism 4 includes a slide 41, a fixed cylinder 42, a pressure regulating plate 43 and a pressure regulating spring 44. The two ends of the slide 41 are open and slidably mounted on the support rod 11. The two ends of the fixed cylinder 42 are closed and mounted outside the slide 41. The height directions of the slide 41 and the fixed cylinder 42 are consistent with the height direction of the support rod 11. The height of the slide 41 is greater than the height of the fixed cylinder 42. The first protective cover 31 is fixedly installed at the lower end of the slide 41. The fixed cylinder 42 is located in the middle of the slide 41. The opposite side walls of the slide 41 are provided with strip holes 411. The strip holes 411 are arranged along the height direction of the slide 41, and the height of the strip holes 411 is less than the inner height of the fixed cylinder 42. In order to further improve the anti-climbing performance of the fixed cylinder 42, the top of the fixed cylinder 42 is set to be truncated, and the diameter of the top of the fixed cylinder 42 increases from bottom to top. A second protective cover 46 is set at the bottom of the fixed cylinder 42, and the outer diameter of the second protective cover 46 decreases from bottom to top. Fixed blocks 421 are fixedly installed on the two opposite inner walls of the bottom of the fixed cylinder 42. The fixed blocks 421 pass through the strip hole 411 and are fixedly connected to the outer wall of the support rod 11, and the fixed blocks 421 are slidably matched with the strip hole 411. The pressure regulating plate 43 is annular and fixedly installed on the outer wall of the sliding cylinder 41. The outer side of the pressure regulating plate 43 is slidably matched with the inner wall of the fixed cylinder 42, and the pressure regulating plate 43 is located above the strip hole 411. The two ends of the pressure regulating spring 44 are fixedly connected to the lower end surface of the pressure regulating plate 43 and the inner bottom wall of the fixed cylinder 42 respectively. When climbing the support pole 11, due to the setting of the slide cylinder 41, the slide cylinder 41 slides relative to the support pole 11 after being stressed, which can effectively prevent people or small animals from climbing to a higher position of the support pole 11. After the slide cylinder 41 is not stressed, under the action of the pressure regulating spring 44, the slide cylinder 41 can be restored to its position, and the protection performance of the tower body 1 can be further improved.

[0032] Reference Figure 3 , Figure 4 and Figure 5In order to further improve the anti-climbing capability, the second anti-climbing mechanism 4 also includes a lubrication component 6. By setting the lubrication component 6, a certain amount of lubricating liquid can be released when climbing the support pole 11, so that the support pole 11 and the slide 41 are easy to slip, preventing people or animals from continuing to climb. The lubrication component 6 includes a liquid pipe 61 and an oil pipe 62. A liquid inlet 412 and a liquid outlet 413 are opened on the side wall of the slide 41. The liquid inlet 412 is located in the fixed cylinder 42 and below the pressure regulating plate 43. The liquid outlet 413 is located outside the fixed cylinder 42 and close to the upper end of the slide 41. The liquid inlet 412 and the liquid outlet 413 are arranged one by one and are located on the same vertical plane. A plurality of liquid inlets 412 and liquid outlets 413 are arranged at intervals along the circumference of the slide 41. A liquid through pipe 61 is arranged between each pair of liquid inlet 412 and liquid outlet 413. The liquid through pipe 61 is located inside the side wall of the slide cylinder 41. The upper end of the liquid through pipe 61 is connected with the liquid outlet 413, and the lower end of the liquid through pipe 61 is connected with the liquid inlet 412. The oil pipe 62 is a hose, and the upper end is fixedly installed on the side wall of the slide cylinder 41. The oil pipe 62 and the liquid through pipe 61 are arranged one by one. The upper end of the oil pipe 62 is connected with the liquid inlet 412, and the lower end of the oil pipe 62 is close to the inner bottom wall of the fixed cylinder 42 and is spaced apart from the inner bottom wall of the fixed cylinder 42. A liquid filling port 422 is fixedly formed on the side wall of the fixed cylinder 42. The liquid filling port 422 is located below the pressure regulating plate 43. A sealing plug 423 is detachably fixedly installed on the liquid filling port 422. The sealing plug 423 can be removed by the maintenance personnel to fill the liquid filling port 422, so that the cavity in the fixed cylinder 42 and between the pressure regulating plate 43 and the bottom of the fixed cylinder 42 can be filled with a certain amount of lubricating liquid. When a person or an animal climbs, the slide cylinder 41 will slide downward along the height direction of the support rod 11, and then the pressure regulating plate 43 can be driven to approach the position of the bottom of the fixed cylinder 42, increasing the pressure in the fixed cylinder 42, so that the lubricating liquid in the fixed cylinder 42 is squeezed into the oil pipe 62, and the lubricating liquid flows out from the liquid outlet 413 along the liquid inlet 412 and the liquid pipe 61, so that the lubricating liquid in the fixed cylinder 42 can flow out to the outer wall of the slide cylinder 41 and the fixed cylinder 42 in time, thereby increasing the obstacle to the climber.

[0033] Reference Figure 3 and Figure 6A support mechanism 7 is installed in the fixed cylinder 42. The support mechanism 7 can open the lower end of the oil pipe 62 in time, so that when the lubricating liquid in the fixed cylinder 42 is squeezed, the lubricating liquid can easily enter the oil pipe 62. The number of the support mechanisms 7 corresponds to the number of the oil pipes 62. The support mechanism 7 includes a bracket 71, a support rod 72, and a driving assembly 8. The bracket 71 is L-shaped. The vertical section of the bracket 71 is fixedly installed on the inner bottom wall of the fixed cylinder 42 and is located in the fixed cylinder 42 near the slide cylinder 41. The horizontal section of the bracket 71 is fixedly connected to one side of the lower end of the oil pipe 62. The opening of the oil pipe 62 Away from the bracket 71, the strut 72 is inserted into the oil pipe 62. The length direction of the strut 72 is consistent with the extension direction of the oil pipe 62 near the bottom position. The strut 72 and the bracket 71 are located on opposite sides of the oil pipe 62, which can effectively open the lower end of the oil pipe 62. The drive component 8 is installed on the inner bottom wall of the fixed cylinder 42 and connected to the strut 72. The drive component 8 can drive the strut 72 to move away from the bracket 71, thereby opening the opening at the lower end of the oil pipe 62, making it easy for the lubricating fluid to enter from the lower end of the oil pipe 62, avoiding the lower end of the oil pipe 62 from being blocked, which may easily lead to poor flow of the lubricating fluid. The driving assembly 8 includes a mounting frame 81 and a driving rod 82. The mounting frame 81 is fixed to a side close to the support rod 72. The driving rod 82 is horizontally arranged above the mounting frame 81, and the middle part of the driving rod 82 is rotatably connected to the mounting frame 81. The lower end of the support rod 72 is fixedly connected to the end of the driving rod 82 close to the oil pipe 62. A gravity block 83 is fixedly installed on the lower end surface of the end of the driving rod 82 away from the oil pipe 62. In addition, a connecting rope 84 is fixedly connected to the corresponding position of the lower end surface of the pressure regulating plate 43 on the upper end surface of the end of the driving rod 82 away from the oil pipe 62. When the pressure regulating plate 43 slides downward without external force, the connecting rope 84 is in a taut state, the driving rod 82 is in a horizontal state, and the support rod 72 is close to the oil pipe 62. 2, when the pressure regulating plate 43 slides downward under pressure, the distance between the pressure regulating plate 43 and the bottom of the fixed cylinder 42 is reduced, so that the connecting rope 84 is loosened, and the pulling force of the connecting rope 84 on the end of the driving rod 82 is reduced. At this time, the gravity of the gravity block 83 is greater than the pulling force of the connecting rope 84 on the end of the driving rod 82, so that the end of the driving rod 82 away from the oil pipe 62 moves toward the bottom of the fixed cylinder 42, driving the end of the driving rod 82 close to the oil pipe 62 to move away from the bottom of the fixed cylinder 42, driving the support rod 72 to contact the inner side wall of the oil pipe 62, so that the support rod 72 moves away from the bracket 71, and the lower end of the oil pipe 62 is opened, so that the lubricating fluid can flow into the oil pipe 62 easily.

[0034] Reference Figure 3 and Figure 5The third anti-climbing mechanism 5 includes a block 51 and a paddle 52. A receiving groove 111 is provided on the outer wall of the support rod 11 and located above the fixed cylinder 42. The receiving groove 111 is an annular groove. The height direction of the receiving groove 111 is consistent with the height direction of the support rod 11. One side of the block 51 is fixedly mounted on the groove wall of the receiving groove 111, and one side of the paddle 52 is fixedly mounted on the inner wall of the slide cylinder 41. Multiple blocks 51 and paddles 52 are arranged at intervals along the height direction of the support rod 11. The number of blocks 51 is greater than the number of paddles 52. Multiple paddles 52 are all close to the lower half of the receiving groove 111. The block 51 near the position of the fixed cylinder 42 corresponds to the paddle 52 one by one. The correspondingly arranged block 51 and paddle 52 have partial overlap. In order to further improve the protective effect of the third anti-climbing mechanism 5, multiple rows of blocks 51 and paddles 52 can be arranged in the circumference of the receiving groove 111. When the slide 41 is forced to move downward along the support rod 11, the paddle 52 has a certain elasticity and rubs and collides with the block 51 to make a sound, which can serve as a prompt to scare away the climber and issue a warning. In order to further improve the overall protective performance, a third protective cover 9 is fixedly installed on the upper end of the slide 11. The outer diameter of the third protective cover 9 decreases from bottom to top, and the liquid outlet 413 is located below the third protective cover 9, which can improve the protection of the liquid outlet 413 and reduce the possibility of the liquid outlet 413 being blocked by dust. A warning sign 91 is also fixedly installed above the slide 41 to facilitate reminders to avoid approaching the power tower.

[0035] The working principle of the embodiment of the present application is: when a person or animal wants to climb the tower body 1, they will climb along the support rod 11. In the embodiment of the present application, the height of the sliding bar is between 2-4 meters, and the length of the support rod 11 is higher than 3 meters, which can improve the protection of the tower body 1 and make it difficult for people or animals to approach the bottom of the tower body 1 and climb.

[0036] When small reptiles climb along the support pole 11 , they will be blocked by the first protective cover 31 , and an insecticidal lamp 32 is arranged below the first protective cover 31 to force back some reptiles and improve the protection of the tower body 1 .

[0037] When a person or an animal climbs the support pole 11, pressure is exerted on the slide cylinder 41, causing the slide cylinder 41 to slide relative to the support pole 11, making it difficult for the climber to further climb up the tower body 1. Furthermore, when the climber causes the slide cylinder 41 to slide downward, the pressure regulating plate 43 on the slide cylinder 41 squeezes the lubricating fluid in the fixed cylinder 42. At the same time, when the pressure regulating plate 43 approaches the bottom of the fixed cylinder 42, the tension of the connecting rope 84 decreases, causing the support pole 72 to open the lower end of the oil pipe 62, so that the bottom of the oil pipe 62 is open, which is conducive to squeezing the lubricating fluid out. The oil pipe 62 is entered by the pressure in the fixed cylinder 42, and the oil pipe 62 is further squeezed by the pressure in the fixed cylinder 42, so that the lubricating fluid in the oil pipe 62 enters the liquid pipe 61 through the liquid inlet 412, and flows out to the outside of the sliding cylinder 41 through the liquid pipe 61. Since the top of the fixed cylinder 42 is a frustum, it is beneficial to further guide the lubricating fluid seeping out of the outside of the sliding cylinder 41, so that the surfaces of the sliding cylinder 41 and the fixed cylinder 42 are evenly covered with lubricating fluid, thereby increasing the smoothness of the surface of the protective device 2 to prevent climbers from continuing to climb the tower body 1, thereby greatly improving the protection capability of the tower body 1.

[0038] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
