Description

Technical Field

[0001] This utility model relates to the field of power facility safety protection technology, and in particular to a power transmission tower with an anti-climbing structure. Background Technology

[0002] Transmission towers, as crucial infrastructure for power transmission, are widely used in the power delivery field. To ensure the safe operation of transmission towers and prevent accidents and damage to power facilities caused by unauthorized personnel climbing them, anti-climb structures have become an indispensable component of transmission towers.

[0003] A search revealed Chinese patent CN222614945U, which discloses a power transmission tower with an anti-climbing structure. The tower includes a base with a tower body fixedly mounted on its upper end and a fixed base connected to its lower side; a groove formed on the outer side of the middle portion of the base, with a supporting structure connected inside the groove; a mounting block installed on the outer side of the lower end of the tower body, with a connecting plate fixedly connected to its outer side; a fixing rod connected to the lower inner side of the connecting plate, and an mounting rod installed on the upper inner side of the connecting plate; an anti-climbing plate connected to the outer upper end of the mounting rod; an anti-climbing block fixedly mounted to the outer lower end of the anti-climbing plate; and a protruding rod connected to the lower side of the anti-climbing block. The outer lower end of the anti-climbing plate is inclined and serves to prevent climbing on the tower base. This power transmission tower with an anti-climbing structure facilitates support, prevents climbing, and allows for easy disassembly of the anti-climbing structure.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] In existing anti-climbing structures for power transmission towers, the angle of the anti-climbing plates is mostly fixed, making it impossible to dynamically adjust the angle according to different environmental needs (such as different terrains and climbing methods). This is because the connection method between the anti-climbing plates and the tower body in existing structures is relatively fixed, lacking a flexible adjustment mechanism. In practical applications, the terrain, surrounding environment, and climbing methods that potential climbers may use vary in different regions, making it difficult for fixed-angle anti-climbing plates to adapt to complex and changing situations. For example, in flat areas with frequent personnel activity, a steeper anti-climbing angle is needed to enhance the protective effect; while in areas with complex terrain and difficult access, the angle may need to be adjusted appropriately to reduce the impact on the surrounding environment. Fixed-angle anti-climbing plates cannot meet diverse protective needs, resulting in a significant reduction in anti-climbing effectiveness, posing safety hazards, and failing to effectively guarantee the operational safety of power transmission towers. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a power transmission tower with an anti-climbing structure. Multiple sets of mounting frames are set at the four corners of the main body of the tower, and adjacent mounting frames are detachably connected by fixing components. At the same time, a rotating shaft mechanism is used to pass through the main protective baffle and connect it to the mounting frame, which can control the anti-climbing baffle to tilt and swing up and down around the outside of the main body of the tower.

[0007] The technical solution to achieve the purpose of this utility model is: a power transmission tower with an anti-climbing structure, including a tower body and further comprising;

[0008] The mounting brackets are provided in two sets at each of the four corners of the power tower body. The tops of the two adjacent mounting brackets at the corners of the power tower body are provided with fixing components, which detachably connect the two sets of mounting brackets.

[0009] The main protective baffle is located on the outer perimeter of the corresponding power tower body, and the two sides of the main protective baffle are located between two mounting brackets.

[0010] A rotating shaft mechanism is provided, which is installed through both sides of the corresponding main protective baffle, and the two ends of the rotating shaft mechanism extend outward through the outside of the two corresponding mounting brackets. The rotating shaft mechanism controls the main protective baffle to tilt and swing up and down around the outside of the power tower body.

[0011] A safety control cabinet, wherein the safety control cabinet is disposed outside the mounting frame, and the two ends of the rotating shaft mechanism extend into the two sets of safety control cabinets;

[0012] The secondary protective baffles are located at the four corners of the main body of the power tower. The four main protective baffles and the four secondary protective baffles form a ring of profile anti-climbing structure around the outside of the main body of the power tower.

[0013] In some embodiments, the mounting bracket includes two sets of limiting brackets, and the fixing component includes a first docking block and a second docking block respectively disposed on the top of the two sets of limiting brackets. The second docking block has a groove on the side near the first docking block, and one end of the first docking block is inserted into the groove of the second docking block. The top of the second docking block is threadedly connected to a first fixing bolt that penetrates one end of the first docking block through the groove.

[0014] In some embodiments, the safety control cabinet includes a safety enclosure installed outside the limit frame, the main protective baffle is a right-angled trapezoidal anti-climb baffle with the inclined surface of the anti-climb baffle facing the outside of the power tower body, and the rotating shaft mechanism includes a rotating shaft rod passing through both sides of the anti-climb baffle, with a steering wheel and a limit nut located inside the safety enclosure at both ends of the rotating shaft rod.

[0015] In some embodiments, a movable door is movably connected to the external opening of the safety enclosure, and a door lock assembly is installed on the outside of the movable door.

[0016] In some embodiments, the secondary protective baffle includes a second baffle with an L-shaped cross-section. The bottom of the second baffle is located at the top of two sets of safety boxes at the corner of the power tower body. The inner surfaces of the two safety boxes are provided with second fixing bolts for threaded fixation to the bottom of the second baffle.

[0017] In some embodiments, each of the anti-climbing baffles has a flow-guiding groove at its bottom that extends through the outer wall of the side closest to the main body of the power tower.

[0018] Compared with existing technologies, the significant advantages of this invention are:

[0019] Firstly, this utility model features multiple mounting brackets at the four corners of the power tower body, with adjacent brackets detachably connected via fixing components. A rotating shaft mechanism passes through the main protective baffle (anti-climb baffle) and connects it to the mounting brackets, allowing for adjustable tilting and swinging of the anti-climb baffle around the power tower body. The main protective baffle and the secondary protective baffle (second baffle) form a ring of profile anti-climbing structure around the power tower body. This structural design makes it difficult for climbers to find a stable foothold, and the baffle's tilt angle can be flexibly adjusted according to actual protection needs, greatly enhancing the anti-climbing capability of the transmission tower, effectively preventing unauthorized personnel from climbing, ensuring the safe operation of the transmission tower, and solving the problems of existing transmission tower anti-climbing structures being fixed, difficult to adjust flexibly, and having poor protective effects.

[0020] Secondly, in this utility model, the top of the limiting frame of the mounting frame is fixed by connecting block one, connecting block two and the first fixing bolt, which realizes the stable connection of the mounting frame at the corner of the power tower body, provides reliable support for the swing adjustment of the main protective baffle, avoids the anti-climbing function being affected by the loosening of the mounting frame, and solves the problem of unstable support foundation of the existing anti-climbing structure.

[0021] Thirdly, the safety control cabinet of this utility model includes a safety enclosure with a movable door equipped with a door lock assembly at its external opening. The two ends of the rotating shaft mechanism extend into the safety enclosure and are equipped with a steering wheel and limit nuts. The rotating shaft mechanism can only be adjusted by opening the movable door through the door lock assembly. This effectively prevents unauthorized personnel from misoperating the mechanism and ensures that the anti-climb barrier adjustment function is controlled only by authorized personnel, solving the problem of existing anti-climb structures being easily adjusted arbitrarily and having poor security.

[0022] Fourthly, the auxiliary protective baffle of this utility model adopts a second baffle with an L-shaped cross-section. Its bottom is fixed to the safety box by a second fixing bolt. Together with the main protective baffle, it forms a continuous closed barrier around the power tower and at the corners, filling the corner gaps, eliminating the risk of climbing, and solving the problem of blind spots in the existing anti-climbing structure.

[0023] Fifthly, this utility model has a drainage groove at the bottom of the anti-climb baffle, which can divert rainwater flowing into the bottom of the baffle outward, preventing rainwater from stagnating and causing the baffle to rust, extending the service life of the structure, and preventing water accumulation from forming a smooth surface to assist climbing, thus indirectly enhancing the anti-climbing effect. This solves the problem that existing anti-climbing structures are easily damaged by rainwater erosion and pose climbing hazards. Attached Figure Description

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0032] This utility model provides an improved power transmission tower with an anti-climbing structure. The technical solution of this utility model is as follows:

[0033] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0034] like Figures 1-4 As shown, a power transmission tower with an anti-climbing structure includes a tower body 100, mounting frames, a main protective baffle, a rotating shaft mechanism, a safety control cabinet, and secondary protective baffles. Two sets of mounting frames are installed at each of the four corners of the tower body 100, and the tops of adjacent mounting frames at each corner are detachably connected via fixing components. The main protective baffle is located on the outer perimeter of the tower body 100, between the left and right mounting frames. The rotating shaft mechanism passes through both sides of the main protective baffle and extends to the outside of the mounting frames, used to control the up-and-down tilting and swinging adjustment of the main protective baffle. The safety control cabinet is located outside the mounting frames, with both ends of the rotating shaft mechanism extending into the interior of the safety control cabinet. The secondary protective baffles are located at the four corners of the tower body 100, forming a ring of profile anti-climbing structure together with the main protective baffles.

[0035] like Figure 3 As shown, in one embodiment, the mounting frame includes two sets of limiting frames 200, and the fixing assembly includes a first docking block 201 and a second docking block 202 disposed on the top of the two sets of limiting frames 200. The second docking block 202 has a groove on the side near the first docking block 201, one end of the first docking block 201 is inserted into the groove, and the top of the second docking block 202 is threadedly connected to and extends through the first fixing bolt 203 to one end of the first docking block 201 within the groove. Through the groove engagement between the first docking block 201 and the second docking block 202, and the threaded fixing of the first fixing bolt 203, a stable connection between the two sets of mounting frames at the corner of the power tower body 100 is achieved, providing a reliable support foundation for the up-and-down swing adjustment of the main protective baffle, ensuring that the anti-climbing function of the main protective baffle is not affected by the loosening of the mounting frame during adjustment.

[0036] In one embodiment, the safety control cabinet includes a safety housing 600 installed outside the limit frame 200. The main protective baffle is a right-angled trapezoidal anti-climb baffle 400, with its inclined surface facing the outside of the power tower body 100. The rotating shaft mechanism includes a rotating shaft rod 300 passing through both sides of the anti-climb baffle 400. A steering wheel 301 and a limit nut 302 are located inside the safety housing 600 at both ends of the rotating shaft rod 300. When the limit nut 302 is loosened, the steering wheel 301 can be manually rotated to rotate the rotating shaft rod 300, thereby causing the anti-climb baffle 400 to rotate up and down around the rotating shaft rod 300. The design of the right-angled trapezoidal inclined surface makes it difficult for climbers to find a point of leverage, and the baffle's tilt angle can be flexibly adjusted according to actual protection needs, enhancing the anti-climb effect. The limit nut 302 can fix the rotating shaft rod 300 after adjustment to a suitable angle, ensuring the baffle's stable position.

[0037] like Figure 1 and Figure 2As shown, in one embodiment, a movable door 601 is movably connected to the external opening of the safety enclosure 600, and a door lock assembly 602 is installed on the outside of the movable door 601. By locking the movable door 601 with the door lock assembly 602, unauthorized personnel can be prevented from opening the safety enclosure 600 at will, and non-staff members can be prevented from accidentally operating the rotating shaft mechanism or disassembling internal components. This ensures that the adjustment function of the anti-climb baffle 400 is controlled only by authorized personnel, further improving the safety and reliability of the transmission tower.

[0038] like Figure 2 and Figure 4 As shown, in one embodiment, the secondary protective baffle includes a second baffle 500 with an L-shaped cross-section. Its bottom is located at the top of two sets of safety enclosures 600 at the corner of the power tower body 100, and the inner surfaces of both safety enclosures 600 are threaded to the bottom of the second baffle 500 via second fixing bolts 501. The L-shaped second baffle 500 cooperates with the main protective baffle anti-climb baffle 400 to form a continuous and closed anti-climb barrier around the power tower body 100 and at the corners, filling the corner gaps between the main protective baffles and eliminating climbing hazards. Simultaneously, the secondary protective baffle is fixed by the second fixing bolts 501 inside the safety enclosure 600, requiring the opening of the movable door 601 for disassembly and assembly. Combined with the protection of the door lock assembly 602, this effectively prevents unauthorized personnel from arbitrarily disassembling the secondary protective baffle, ensuring the integrity of the overall anti-climb structure.

[0039] like Figure 2 As shown, in one embodiment, each anti-climb baffle 400 has a guide groove 401 extending through the outer wall of the side closest to the main body 100 of the power tower at its bottom. When external rainwater flows into the bottom of the anti-climb baffle 400, the rainwater will be diverted outward along the groove path of the guide groove 401, preventing rainwater from accumulating on the top of the baffle. This design can prevent rainwater from accumulating for a long time and causing the baffle to rust, extending the service life of the anti-climb structure. At the same time, it prevents water accumulation from forming a smooth surface, preventing climbers from using the adhesion of the water surface to assist in climbing, thus indirectly enhancing the anti-climb effect.

[0040] Working principle and usage process of this utility model:

[0041] When adjusting the tilt angle of the anti-climb baffle 400, first open the movable door 601 of the safety box 600 through the door lock assembly 602, loosen the limit nut 302, manually rotate the steering wheel 301 to rotate the rotating shaft rod 300, causing the anti-climb baffle 400 to flip up and down around the rotating shaft rod 300 to the required angle. Then tighten the limit nut 302 to fix the rotating shaft rod 300. When installing or removing the secondary protective baffle (second baffle 500), the movable door 601 must also be opened, and the threaded connection or disassembly operation is performed through the second fixing bolt 501. During normal use, the movable door 601 is locked by the door lock assembly 602 to ensure the stability and safety of the anti-climb structure. The closed barrier formed by the main protective baffle and the secondary protective baffle, along with the inclined slope design, effectively prevents personnel from climbing the main body of the power tower 100.

[0042] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
