Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to an anti-mistaken entry device for a wind power generator set. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind rotor, a generator, a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft.

[0003] In an anti-mistaken-entry device for a wind turbine generator set disclosed in my country's utility model patent CN221372714U, a first baffle, a connecting member and a second baffle are provided, and the second baffle is used to block the passage, while the first baffle is used to block climbing over, so as to achieve an anti-mistaken-entry effect. However, in this design, it is impossible to prevent the person who has misentered from passing through the gap between the handrails on both sides of the passage driven by curiosity, and then climbing over the second baffle by holding the handrail. At the same time, if the person who has misentered climbs over the second baffle sideways, there is still a great risk that he or she may accidentally fall and cause injury. Therefore, we propose an anti-mistaken-entry device for a wind turbine generator set to solve the above problems. Utility Model Content

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments

[0024] Refer to Figures 1-3 , an anti-misentry device for a wind turbine, including a stepped channel 1 and a handrail 2. A blocking structure is provided on the stepped channel 1, and a protective plate 3 is provided on the side wall of the stepped channel 1 close to the blocking structure

[0025] The blocking structure includes a sliding plate 4 fixedly connected to the stepped channel 1. A sunk groove 5 is formed on the sliding plate 4, and a strip-shaped hole is formed in the sunk groove 5. A cross frame 6 is slidably connected to the lower end of the stepped channel 1. A plurality of pedals 7 are fixedly connected to the cross frame 6, and the pedals 7 are slidably connected to the strip-shaped hole. In this design, the pedals 7 are slightly inclined to prevent users from slipping and falling when climbing on the pedals 7, improving the safety of the blocking structure. One end of the pedal 7 away from the cross frame 6 is fixedly connected to a baffle 8. A support rod 9 is also fixedly connected to the cross frame 6. A relief groove matching the support rod 9 is formed on the protective plate 3. A counterweight is provided on one side of the cross frame 6, and a pull rod 10 is provided at one end of the cross frame 6 close to the stepped channel 1. A grip for driving the pull rod 10 is provided on the pull rod 10. During the operation of the blocking structure, the grip is taken away by the user, so that the misentry person cannot operate the pull rod 10

[0026] In this design, when the blocking structure is in operation, the user controls the cross frame 6 to slide downwardly under the action of gravity, and the multiple pedals 7 pass through the strip holes and are located below the slide plate 4. At this time, the baffle plate 8 is stuck in the sink 5, which can not only further fix the cross frame 6 to ensure that the cross frame 6 will not continue to slide downward, but also fill the sink 5. At this time, the upper surface of the entire slide plate 4 is in an inclined and smooth state without force. In this state, the stray person cannot pass through the blocking structure by climbing the slide plate 4, and the protective plate 3 is provided to prevent the stray person from sliding down from both sides of the slide plate 4, thereby improving the safety of the entire structure.

[0027] When the user needs to pass through the blocking structure, the user uses the handle to pull the pull cover, driving the pedal 7 to pass through the strip hole and move to the top of the skateboard 4. At this time, the user can use the pedal 7 as a step to move upward, meeting the needs of professionals to pass. In addition, by setting the handrail 9, it is convenient for the user to stabilize his body when passing through the blocking structure to avoid falling.

[0028] Furthermore, the step channel 1 is fixedly connected to a limit platform 11 near the upper surface of the pull rod 10, and a clearance hole is provided on the limit platform 11. The inner wall of the pull rod 10 is fixedly connected to a connecting sleeve 12, and the inner wall of the connecting sleeve 12 is provided with a spiral groove 13, and the inner wall of the connecting sleeve 12 is provided with a clamping groove 14;

[0029] In this design, the limit platform 11 is mainly used to prevent the user from pulling the pull rod 10 upward by hand through the gap, and to prevent the user from forcibly pulling the pull rod 10 without the help of the handle. By setting the connecting sleeve 12 in conjunction with the spiral groove 13 and the card groove 14, the user can better use the handle to drive the pull rod 10 to move.

[0030] Furthermore, the grip includes a handle 15, one end of the handle 15 is fixedly connected to a connecting rod 16, and one end of the connecting rod 16 away from the handle 15 is fixedly connected to a cross bar 17 matching the card slot 14;

[0031] In this design, the user holds the handle 15 and inserts the cross bar 17 into the connecting sleeve 12, and then rotates the handle 15 so that the cross bar 17 moves along the spiral groove 13 and finally snaps into the snap groove 14. At this time, the user pulls the handle 15 upward to cooperate with the pull rod 10 to drive the cross frame 6 to move upward.

[0032] Furthermore, one end of the handrail 2 close to the connecting rod 9 is slidably connected with a sliding sleeve 18, and the inner diameter of the sliding sleeve 18 is the same as that of the handrail 9. In this design, after the user pulls the cross bar 17 upward, the sliding sleeve 18 is slid to put it on the handrail 9, and the sliding sleeve 18 is used to make the handrail 9 coaxial with the handrail 2, thereby fixing the cross frame 6 in this state, making it convenient for the user to pass through the blocking structure.

[0033] Furthermore, external threads are provided on the handrail 9, and a threaded sleeve 19 that mates with the external threads is rotatably connected to the sliding sleeve 18. In this design, the external threads cooperate with the threaded sleeve 19 to relatively fix the handrail 9 and the sliding sleeve 18, preventing the cross frame 6 from dropping due to the sliding of the sliding sleeve 18 relative to the handrail 9 when the user passes through the blocking structure.

[0034] Furthermore, the protective plate 3 is in a U shape, and both the protective plate 3 and the sliding plate 4 are made of polished stainless steel. Since it is necessary to ensure the smoothness of the protective plate 3 and the sliding plate 4, polishing treatment is used to make their surfaces smoother. This also makes it difficult to cover a protective paint film on the surface of the sliding plate 4, so stainless steel is used. The U-shaped protective plate 3 is provided to ensure that when a person who has strayed wants to pass through the sliding plate 4, the protective plate 3 can play a protective role and the person who has strayed cannot use the protective plate 3 to climb by leveraging.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
