[0022] Please refer to Figures 1-4This application provides a base for installing a power transmission tower, including: a support for supporting the power transmission tower, the support including columns 1 and crossbars 2, the columns 1 being four in number, the four columns 1 being connected to each other by the crossbars 2; and an anti-climbing mechanism, the anti-climbing mechanism including a transverse anti-climbing plate 3 and a longitudinal anti-climbing plate 4, the transverse anti-climbing plate 3 being disposed on the crossbars 2, the transverse anti-climbing plate 3 extending out of the support formed by the columns 1, and the longitudinal anti-climbing plate 4 being circumferentially disposed at the edge of the transverse anti-climbing plate 3.

[0023] In this embodiment, the aforementioned support structure consists of four uprights 1 and several crossbars 2. The four uprights 1 are connected in pairs via crossbars 2 to form a stable frame structure. The crossbars 2 are distributed at different heights, and the anti-climbing mechanism is located on the crossbars 2 in the upper middle part of the support. The frame structure is a four-legged support, which provides a solid supporting foundation for the transmission tower through a reasonable layout and connection method. It should be noted that the transmission tower itself has a large weight and will also bear vertical loads such as the tension of the transmission line during operation. The four uprights 1 are evenly distributed at the four corners of the base, which can evenly transfer the vertical load of the transmission tower to the foundation, avoiding local stress concentration that could lead to foundation settlement or structural damage.

[0024] In nature, transmission towers are subjected to horizontal loads such as wind and seismic forces. The crossbar 2 connects the four columns 1 into a single unit, enhancing the rigidity and stability of the support structure. When subjected to horizontal loads, the crossbar 2 and columns 1 work together to dissipate and disperse the horizontal force through the deformation of the frame structure, ensuring the horizontal stability of the transmission tower and preventing it from tipping over. The frame structure composed of the four columns 1 and the crossbar 2 possesses high strength and rigidity, capable of withstanding large loads, providing reliable support for the transmission tower and ensuring its stable operation in various harsh environments.

[0025] Furthermore, the aforementioned transverse climbing barrier 3 is installed on the crossbar 2 and extends outwards to form a support structure with the uprights 1. The portion of the transverse climbing barrier 3 extending outwards from the support structure forms a physical barrier. When someone attempts to climb the transmission tower, the transverse climbing barrier 3 blocks their hand and foot grip points, preventing them from climbing smoothly. In areas with frequent human activity, such as the outskirts of cities or near schools, the transverse climbing barrier 3 can prevent children or curious individuals from accidentally climbing the transmission tower, reducing the occurrence of safety accidents such as electric shock and falls, and protecting the lives of personnel.

[0026] In this embodiment, the longitudinal climbing barrier 4 is circumferentially disposed at the edge of the transverse climbing barrier 3 and is perpendicularly connected to the transverse climbing barrier 3, forming a surrounding structure. The longitudinal climbing barrier 4, based on the transverse climbing barrier 3, blocks the climber vertically. When the climber attempts to bypass the transverse climbing barrier 3 to continue climbing, the longitudinal climbing barrier 4 further increases the difficulty of climbing.

[0027] Specifically, the transverse anti-climbing plate 3 and the longitudinal anti-climbing plate 4 work together to form a multi-layered anti-climbing system, greatly improving the reliability and effectiveness of anti-climbing. Even if the transverse anti-climbing plate 3 is partially damaged or bypassed, the longitudinal anti-climbing plate 4 can still play a blocking role, ensuring the safety of the transmission tower.

[0028] Please refer to Figures 1-4 In some embodiments of this example, the aforementioned transverse anti-climbing plate 3 includes an inner anti-climbing plate 301, an outer anti-climbing plate 302, and a support beam 303. The support beam 303 is disposed on the crossbar 2, and both the inner anti-climbing plate 301 and the outer anti-climbing plate 302 are disposed on the support beam 303.

[0029] In this embodiment, the aforementioned support beams 303 are two rods that traverse the entire support frame. The support beams 303 are mounted on the crossbar 2 and are used to install the inner baffle plate 301 and the outer baffle plate 302. They bear the weight of the inner baffle plate 301 and the outer baffle plate 302, and transmit external forces to the crossbar 2. Through a secure connection with the crossbar 2, such as welding or bolting, the entire transverse anti-climbing plate 3 structure is stably attached to the support frame.

[0030] When a climber attempts to climb the transmission tower and applies external force to the anti-climb plate, the support beam 303 can evenly distribute this force to the crossbar 2, and then the crossbar 2 transmits it to the entire support structure, avoiding local stress concentration that could lead to structural damage.

[0031] Furthermore, the aforementioned inner barrier plate 301 is located inside the support structure, and its main function is to prevent climbers from climbing upwards from inside the transmission tower. When someone attempts to climb from inside the support structure, the inner barrier plate 301 forms a physical barrier, blocking their hand and foot grip points. The outer barrier plate 302 is located on the outer perimeter of the support structure and serves as the first line of defense against external personnel climbing the transmission tower, increasing the difficulty of climbing the support structure.

[0032] Specifically, the support beam 303 serves as the basic support structure, organically connecting the inner barrier plate 301 and the outer barrier plate 302 together and fixing them to the crossbar 2. The inner barrier plate 301 and the outer barrier plate 302 function from both the inside and outside of the transmission tower, forming a complementary and collaborative anti-climbing system. When a climber attempts to climb the transmission tower from different directions, the inner barrier plate 301 and the outer barrier plate 302 simultaneously act as a barrier, while the support beam 303 transfers the external force applied by the climber to the crossbar 2 and the entire support structure, ensuring that the entire transverse anti-climbing plate system can stably withstand external forces and maintain the integrity of the structure.

[0033] Please refer to Figures 1-4In some embodiments of this example, a ladder 5 is provided inside the bracket, and an opening 6 for the ladder 5 is provided on the inner barrier plate 301. A sealing plate 7 is provided on the opening 6, and the sealing plate 7 is hinged to the inner barrier plate 301 by a hinge.

[0034] In this embodiment, a ladder 5 is installed within the aforementioned support frame to facilitate climbing for authorized personnel, such as power workers, when inspecting, maintaining, or repairing the tower. The ladder 5 is typically designed and installed with a specific slope and spacing, and its steps provide stable footholds for workers, facilitating their safe ascent and descent from the tower. The ladder 5 guides workers to climb along designated paths, preventing potential accidents caused by haphazard climbing within the tower. It also helps standardize work procedures and improve work efficiency.

[0035] Furthermore, since a ladder 5 is installed inside the support frame, and the main function of the inner barrier plate 301 is to prevent unauthorized climbing, an opening 6 is made in the inner barrier plate 301 to ensure that the presence of the inner barrier plate 301 does not affect the normal access of authorized personnel to the tower via the ladder 5. The position and size of the opening 6 are set according to the actual position and specifications of the ladder 5 to ensure that the ladder 5 can pass smoothly through the opening 6, while not affecting the blocking effect of the inner barrier plate 301 on other unauthorized climbing paths.

[0036] It should be noted that the aforementioned sealing plate 7, by covering the opening 6, can seal the opening 6 when the ladder 5 is not needed, preventing unauthorized personnel from climbing into the tower through the opening 6. The size and shape of the sealing plate 7 match the opening 6, allowing it to tightly cover the opening 6 and effectively block access.

[0037] When authorized personnel need to use ladder 5, the sealing plate 7 can be opened to allow opening 6 to pass freely; after the work is completed, the sealing plate 7 can be put back over opening 6 to restore the anti-illegal climbing state. This responsive opening and closing method ensures both the convenience of authorized operations and maximizes the safety of the tower.

[0038] Please refer to Figures 1-4 In some embodiments of this example, both the blocking plate 7 and the inner resistance plate 301 are provided with supports 8 for passing through the lock body.

[0039] In this embodiment, supports 8 for mounting the lock body are respectively provided on the inner barrier plate 301 and the sealing plate 7 to adapt to common lock body structures. The supports 8 are firmly fixed to the corresponding positions of the inner barrier plate 301 and the sealing plate 7 by welding or bolting, providing a stable foundation for the installation of the lock body.

[0040] Specifically, the aforementioned lock body is used to connect the two supports 8 after installation. When it is necessary to lock the sealing plate 7, the lock tongue or other locking components of the lock body extend, allowing them to engage with the specific structure on the corresponding support 8 or inner barrier plate 301 to form a locked state. By setting up the lock body and supports 8, the sealing plate 7 can be firmly locked onto the inner barrier plate 301, effectively preventing unauthorized personnel from climbing into the interior of transmission towers and other facilities by opening the sealing plate 7. Even if unauthorized personnel attempt to damage the sealing plate 7 or other parts of the inner barrier plate 301, the presence of the lock body increases the difficulty and time cost for them to carry out illegal activities, thereby improving overall security.

[0041] Please refer to Figures 1-4 In some embodiments of this example, the bottom of the column 1 is provided with a positioning plate 9 for connecting with the pre-cast screw of the transmission tower, and the positioning plate 9 is provided with several docking holes.

[0042] In this embodiment, the positioning plate 9 is installed at the bottom of the column 1 to provide a precise positioning reference for the installation of the column 1 on the transmission tower. During the construction of the transmission tower, the pre-cast bolts are fixed in advance in the tower foundation concrete, having a definite position and orientation. The positioning plate 9 is set according to the layout and spacing of the pre-cast bolts. When the column 1 is installed on the tower, the positioning plate 9 can precisely align with the pre-cast bolts, ensuring that the column 1 is accurately positioned in both the horizontal and vertical directions.

[0043] In this embodiment, the aforementioned mating holes are designed to align with the pre-cast bolts of the transmission tower. The number, position, and size of the mating holes correspond one-to-one with the pre-cast bolts. When installing the column 1, the pre-cast bolts are passed through the mating holes on the positioning plate 9, and then the positioning plate 9 is securely connected to the bolts using nuts or other fasteners. This precise connection between the positioning plate 9 and the pre-cast bolts ensures a reliable connection between the column 1 and the tower foundation.

[0044] Please refer to Figures 1-4 In some embodiments of this example, the top of the bracket is provided with a locking plate 11 that is connected to the transmission tower, and the locking plate 11 is provided with a corresponding locking hole 12 for inserting screws.

[0045] In this embodiment, the locking plate 11 is fixedly installed on the top of the support, providing a dedicated and stable structural platform for the connection between the support and the transmission tower. During installation, the locking plate 11 fits tightly against the corresponding part of the transmission tower, and uses its own strength and rigidity to bear and transmit the force between the support and the tower.

[0046] In this embodiment, the locking plate 11 is provided with a positioning flange, which is used to position the mounting base of the transmission tower, which can greatly improve the installation efficiency.

[0047] Please refer to Figures 1-4 In some embodiments of this example, the transverse anti-climb plate 3 is a grid plate.

[0048] In this embodiment, the aforementioned mesh plate is formed by arranging steel wires at a certain spacing and direction, and connecting them to the crossbars 2 through manual welding, creating a plate-like structure with regular grid holes. This mesh plate structure allows for relatively reduced weight while maintaining high strength. Compared to solid plates, the mesh plate, with the same amount of material, can withstand greater loads due to its hollow grid structure, and is easier to handle and install, reducing construction difficulty and cost.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
