[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a power transmission tower with anti-fall function, comprising:

[0024] A concrete base 1, on the top of which the main body of the power tower 11 is fixedly installed;

[0025] Fall protection climbing mechanism 2 is installed on the main body 11 of the power tower and is used for fall protection.

[0026] The climbing de-icing mechanism 3 is installed on the top of the concrete base 1 and is used to de-ice the fall-prevention climbing mechanism 2.

[0027] The fall-prevention climbing mechanism 2 includes a central crossbar 27 and a support block 275. A rotating assembly 271 is rotatably connected to the outer wall of the central crossbar 27. A protective plate 272 is fixedly installed on the outer wall of the rotating assembly 271. A through hole 273 is opened at the top of the protective plate 272. An extension block 274 is fixedly installed on the outer wall of the protective plate 272. A rubber block 276 is fixedly installed at the top of the support block 275. The protective plate 272 is used to shield the worker from below, realizing the function of preventing vertical falls and increasing safety. The protective plate 272 is rotatably connected to the central crossbar 27 via the rotating assembly 271. During the user's movement, the protective plate 272 can be rotated open to facilitate passage. The opening angle of the protective plate 272 is less than 90 degrees. After opening, it will automatically close under the action of gravity. The rubber block 276 can produce elastic deformation to buffer the impact force of the closing of the protective plate 272, reducing noise and vibration damage.

[0028] As one implementation method in this embodiment, such as Figure 2 As shown, the fall-prevention climbing mechanism 2 also includes a crossbeam 21, which is fixedly installed on the outer wall of the main body 11 of the power tower. A first reinforcement member 23 is fixedly installed on the outer wall of the crossbeam 21. The end of the first reinforcement member 23 away from the crossbeam 21 is fixedly installed on the outer wall of the main body 11 of the power tower. A vertical rod 22 is fixedly installed on the crossbeam 21. A second reinforcement member 24 is fixedly installed on the outer wall of the vertical rod 22. The end of the second reinforcement member 24 away from the vertical rod 22 is fixedly installed on the outer wall of the crossbeam 21. Through the design of the crossbeam 21 and the vertical rod 22, the entire fall-prevention climbing mechanism 2 can be supported. Through the design of the first reinforcement member 23 and the second reinforcement member 24, the crossbeam 21 and the vertical rod 22 can be reinforced.

[0029] As one implementation method in this embodiment, such as Figure 2 As shown, the middle horizontal bar 27 is fixedly installed on the outer wall inside the vertical bar 22, the support block 275 is fixedly installed on the side of the vertical bar 22, the climbing horizontal bar 25 is fixedly installed on the outer wall inside the vertical bar 22, and the arc-shaped protective bar 26 is fixedly installed on the side of the vertical bar 22. The design of the climbing horizontal bar 25 allows users to climb, and the design of the arc-shaped protective bar 26 prevents users from falling from the side when climbing in its inner cavity.

[0030] As one implementation method in this embodiment, such as Figure 4As shown, the climbing de-icing mechanism 3 includes a vertical square tube 31, which is fixedly installed on the top of the concrete base 1. A support sleeve 32 is fixedly sleeved on the outer wall of the vertical square tube 31, and the support sleeve 32 is fixedly installed on the top of the concrete base 1. A reinforcing leg 33 is fixedly installed on the outer wall of the support sleeve 32, and the reinforcing leg 33 is fixedly installed on the top of the concrete base 1. Through the design of the support sleeve 32 and the reinforcing leg 33, the vertical square tube 31 can be stably supported on the top of the concrete base 1.

[0031] As one implementation method in this embodiment, such as Figure 4 As shown, a hollow tube 34 is fixedly connected to the side of the vertical square tube 31. An exhaust hole 35 is provided on the side of the hollow tube 34 away from the vertical square tube 31. If the climbing crossbar 25 is covered with ice, the safety of the climbing work will be greatly reduced. At this time, the user can use a hot air blower to introduce hot air into the inner cavity of the vertical square tube 31. The hollow tube 34 corresponds one-to-one with the climbing crossbar 25 and the middle crossbar 27. The hot air is then sprayed out from the exhaust hole 35 to heat and remove the ice on the climbing crossbar 25 and the middle crossbar 27, thereby increasing the safety during the climbing process.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, a bend 36 is fixedly connected to the side of the vertical square tube 31 away from the hollow tube 34. An anti-loss rope 37 is fixedly installed on the outer wall of the bend 36. A sealing cover 38 is fixedly installed at the end of the anti-loss rope 37 away from the bend 36. The sealing cover 38 is threaded to the bottom of the bend 36. In the initial state, the sealing cover 38 is connected to the bottom of the bend 36 to prevent dust from entering the bottom of the bend 36. The output end of the hot air blower is pre-installed with the interface corresponding to the bottom of the bend 36. When in use, the sealing cover 38 is removed, and then the interface of the hot air blower is connected to the bottom of the bend 36 to deliver hot air into the interior of the vertical square tube 31.

[0033] Working principle: When in use, if the climbing crossbar 25 is covered with ice, remove the sealing cover 38, then connect the hot air blower interface to the bottom of the bent pipe 36, control the hot air blower to operate, and introduce hot air into the inner cavity of the vertical square tube 31. The hollow tube 34 corresponds one-to-one with the climbing crossbar 25 and the middle crossbar 27, and the hot air is then sprayed out from the exhaust hole 35 to heat and remove the ice on the climbing crossbar 25 and the middle crossbar 27. The worker can then climb from the climbing crossbar 25 in the inner cavity of the arc-shaped protective bar 26. During the climbing process, the protective plate 272 can be manually rotated to open. Because the opening angle of the protective plate 272 is less than 90 degrees, it will automatically close under the action of gravity after opening. At this time, the protective plate 272 is used to shield the worker from below, realizing the function of preventing vertical falls.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
