[0028] 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.

[0029] like Figures 1-7As shown, this utility model provides a technical solution: a wind turbine tower, including a base 1 and a tower body 2. The top of the base 1 is provided with the tower body 2 for installing a wind turbine. The generator set 202 is conveniently installed on the top of the tower body 2 via a connecting seat 201. The generator set 202 facilitates the conversion of wind kinetic energy into electrical energy. The inner side of the tower body 2 is provided with a non-climbing mechanism 3 for workers to avoid climbing. The non-climbing mechanism 3 includes columns 301, which are configured as two sets. The bottom ends of the two sets of columns 301 are fixedly installed on the top of the base 1. The top ends of the two sets of columns 301 are fixedly connected to the inner wall of the connecting seat 201. A guide groove 302 is opened on one side of the outer wall of the two sets of columns 301. A rotating wheel 303 is rotatably installed on the top of the two sets of columns 301 via a mounting bracket. A guide block 304 is slidably installed inside the two sets of guide grooves 302. A base plate is fixedly connected to the end of the two sets of guide blocks 304 away from the two sets of guide grooves 302. 305. The base plate 305 is fixedly connected to one end of the steel cable 5 near the two sets of guide blocks 304 via a connecting block. The surface of the steel cable 5 away from the base plate 305 overlaps the inner surface of the rotating wheel 303. The top of the base plate 305 near the two sets of columns 301 is fixedly connected to a back plate 306. Handrails 307 are fixedly installed on both sides of the top of the base plate 305. The base plate 305 facilitates standing on its top, and the back plate 306 facilitates the worker to lean against its surface. By holding the two sets of handrails 307, the worker can stabilize their body on the top of the base plate 305. The rotating wheel 303 drives the base plate 305 at the other end of the steel cable 5 to rise with the rotation of the take-up roller 602. This causes the base plate 305 to slide upward through the two sets of guide blocks 304 inside the two sets of guide grooves 302 and move steadily upward on the surface of the two sets of columns 301. The upward movement of the base plate 305 allows the worker to rise into the interior of the connecting seat 201.

[0030] As one implementation method in this embodiment, such as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, a protective mechanism 4 for protecting workers is provided on one side of the outer wall of the non-climbing mechanism 3. The protective mechanism 4 includes protective shoulder straps 401, which are configured as two sets. Both sets of protective shoulder straps 401 are installed on both sides of the surface of the back plate 306 via mounting parts. The ends of both sets of protective shoulder straps 401 away from the back plate 306 are fixedly connected to connecting straps 402. One set of connecting straps 402 away from one set of protective shoulder straps 401 is equipped with spring plates 403 via connecting parts. There are two sets of spring plates 403, and the ends of both sets of spring plates 403 away from one set of connecting straps 402 are fixedly installed with snap-fit ​​connectors 404. The other set of connecting straps 402 is fixedly connected to a connecting sleeve 405 via connecting parts. The outer walls of the connecting sleeve 405 are provided with snap-fit ​​grooves 406 on both sides. The ends of the two sets of snap-fit ​​connectors 404 away from the two sets of spring plates 403 are inserted into the two sets of snap-fit ​​grooves 406. Workers pass their arms through the two sets of protective shoulder straps 401 respectively, and then... The worker wears a set of protective harnesses 401 on their upper body. Simultaneously, the worker holds two sets of connecting straps 402 and wraps them around their chest to align the two sets of locking connectors 404 at one end of the two sets of spring plates 403 with the inlet of the connecting sleeve 405. Once the two sets of spring plates 403 and the two sets of locking connectors 404 are aligned with the connecting sleeve 405, the worker manually inserts the two sets of spring plates 403 and the two sets of locking connectors 404 into the inside of the connecting sleeve 405. At the same time, the elastic force of the two sets of spring plates 403 drives the two sets of snap-fit ​​connectors 404 to snap into the inside of the two sets of snap-fit ​​grooves 406, which facilitates the fixing of the two sets of spring plates 403 and connecting sleeves 405. The two sets of spring plates 403 and connecting sleeves 405, after being fixed, fix the two sets of connecting straps 402 to the chest of the worker. The two sets of fixed connecting straps 402 facilitate the fixing of the two sets of protective back straps 401 to the upper body of the worker, making it convenient to restrain the worker on the surface of the back panel 306.

[0031] As one implementation method in this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the inner side of the non-climbing mechanism 3 is provided with a steel cable 5 for hoisting the non-climbing mechanism 3, and the bottom end of the base 1 is provided with a winding mechanism 6 for winding and unwinding the steel cable 5. The winding mechanism 6 includes a shaft frame 601, the bottom end of which is fixedly installed inside the base 1. A winding roller 602 is rotatably installed on the inner side of the shaft frame 601. The surface of the winding roller 602 is connected to the other end of the steel cable 5. A servo motor 603 is fixedly installed on one side of the outer wall of the shaft frame 601 through a mounting plate. The output end of the servo motor 603 is fixedly connected to one end of the winding roller 602 through a shaft.

[0032] Working principle: When workers need to install or maintain generator set 202, they first enter the tower body 2, then stand on top of the base plate 305. The worker then turns around with their back against the back plate 306, and puts their arms through two sets of protective back straps 401, covering their upper body. Simultaneously, the worker holds two sets of connecting straps 402 and wraps them around their chest to align the two sets of clamping connectors 404 at one end of the two sets of spring plates 403 with the inlet of the connecting sleeve 405. Once the two sets of spring plates 403 and the two sets of clamping connectors 404 are aligned with the connecting sleeve 405, the worker manually inserts the two sets of spring plates 403 and the two sets of clamping connectors 404 into the inside of the connecting sleeve 405. 03 While being inserted into the connecting sleeve 405, the elastic force of the two sets of spring plates 403 drives the two sets of snap-fit ​​connectors 404 to snap into the inside of the two sets of snap-fit ​​slots 406, which facilitates the fixation of the two sets of spring plates 403 and the connecting sleeve 405. The two sets of spring plates 403 and the connecting sleeve 405 are fixed together, thereby fixing the two sets of connecting straps 402 to the chest of the worker. The two sets of fixed connecting straps 402 facilitate the fixation of the two sets of protective back straps 401 to the upper body of the worker, which facilitates the restraint of the worker on the surface of the back plate 306. At the same time, the worker holds onto the two sets of handrails 307, which helps to stabilize the body on the top of the base plate 305, which plays a role in safety protection for the worker and prevents the worker from falling off the top of the base plate 305 during the ascent.

[0033] When the worker has taken safety precautions on the base plate 305, the servo motor 603 is started to drive the winding roller 602 to rotate inside the shaft frame 601. The rotating winding roller 602 winds up the steel cable 5 wrapped around its surface. The force generated by the rotating winding roller 602 drives the rotating wheel 303 to rotate through the steel cable 5. The rotating wheel 303 drives the base plate 305 at the other end of the steel cable 5 to rise upward with the force of the rotating winding roller 602. This causes the base plate 305 to slide upward through the two sets of guide blocks 304 inside the two sets of guide grooves 302 and move steadily upward on the surface of the two sets of columns 301. The upward movement of the base plate 305 raises the worker to the inside of the connecting seat 201. When the worker reaches the inside of the connecting seat 201, the worker manually releases the protective mechanism 4 to facilitate the worker's entry into the generator set 202 for installation and maintenance.

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