[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a wind turbine gearbox internal testing device, the wind turbine gearbox internal testing device includes: a testing instrument body 1, a handle 2 is provided on the side of the testing instrument body 1, a base plate 3 is provided on the end face of the handle 2, a cover 4 is provided on the side of the base plate 3, a storage groove 5 is opened in the base plate 3, and a positioning rod 6 is provided in the storage groove 5.

[0023] The traction belt 7 has a positioning hook 8 on its end face. The positioning hook 8 has a limit rod 9 and a fixing rod 10 on its side. An auxiliary plate 11 is sleeved on the surface of the fixing rod 10.

[0024] The gearbox of the wind turbine can be inspected through the instrument body 1. When the instrument body 1 is not in use, the cover 4 can be opened, and then the positioning hook 8 can be pulled out with the traction belt 7. The positioning hook 8 can be hooked onto the worker's body with the auxiliary plate 11, so that the worker can carry the instrument body 1 without having to hold it in his hand all the time.

[0025] Example 2: Based on Example 1, a traction belt 7 is provided to facilitate carrying the detector body 1. One end of the traction belt 7 is fixedly connected to the side of the positioning rod 6, and the other end of the traction belt 7 is fixedly connected to the end face of the positioning hook 8. A traction frame 16 is provided in the storage slot 5. The traction frame 16 has a square frame structure. The traction belt 7 passes through the traction frame 16. The auxiliary plate 11 can rotate around the fixed rod 10. The limiting rod 9 can limit the rotation of the auxiliary plate 11. A limiting spring 17 is sleeved on the surface of the fixed rod 10. One end of the limiting spring 17 is fixedly connected to the side of the auxiliary plate 11, and the other end of the limiting spring 17 is fixedly connected to the surface of the fixed rod 10.

[0026] When in use, the detector body 1 can be hooked onto the worker's body by the positioning hook 8 set at one end of the traction belt 7. When hooking the detector body 1, the auxiliary plate 11 can be pressed to move the auxiliary plate 11 backward, and then the positioning hook 8 can be hung on the body. The auxiliary plate 11 can be reset by the torque of the limit spring 17, which can work with the limit rod 9 to prevent the positioning hook 8 from falling off the worker's body. The setting of the limit spring 17 also prevents the auxiliary plate 11 from rotating arbitrarily. The setting of the traction frame 16 can guide the traction belt 7 and also prevent the positioning hook 8 from being stored inside the storage slot 5. The positioning hook 8 cannot pass through the traction frame 16.

[0027] Example 3: Based on Example 2, a positioning rod 6 is provided for convenient storage of the traction belt 7. The base plate 3 is fixedly connected to the end face of the handle 2. The outer side of the base plate 3 is provided with a Velcro flat surface 12, the inner side of the cover 4 is provided with a Velcro rough surface 13, the surface of the storage groove 5 is provided with a limit bearing 14, one end of the positioning rod 6 is fixedly connected to the inner ring surface of the limit bearing 14, the other end of the positioning rod 6 passes through the base plate 3, and the other end of the positioning rod 6 is provided with a rotating disk 15.

[0028] In use, rotating the rotating disk 15 allows the positioning rod 6 to rotate in conjunction with the limit bearing 14, facilitating the winding of the traction belt 7. The traction belt 7 can be wound onto the positioning rod 6, allowing the traction belt 7 and positioning hook 8 to be easily stored in the storage slot 5. Then, pulling the cover 4 utilizes the adhesion between the Velcro flat surface 12 and the Velcro rough surface 13 to cover the side of the storage slot 5, thus preventing the traction belt 7 and positioning hook 8 from being exposed to the outside, and thus facilitating the storage of the traction belt 7 and positioning hook 8 in the storage slot 5.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
