[0023] See also Figure 1-4 The utility model provides a technical solution: a wind power gearbox with an impact protection structure, including a wind power gearbox mechanism 1, the wind power gearbox mechanism 1 is fastened with a protection mechanism 2 on both sides, and the protection mechanism 2 includes a protection plate 21 and a shock absorbing spring 22, the shock absorbing spring 22 is fixedly connected to the four corners of the surface of one side of the protection plate 21, one end of the shock absorbing spring 22 is fixedly connected to a fixing plate 23, and the edge of the surface of one side of the fixing plate 23 is evenly penetrated with fixing holes 231; the wind power gearbox mechanism 1 includes a first wind power gearbox 11 and a second wind power gearbox Box 12, and the No. 2 wind turbine gearbox 12 is plugged into the side surface of the No. 1 wind turbine gearbox 11; the No. 1 wind turbine gearbox 11 is symmetrically fixedly connected with fixed columns 16 at both ends, and the No. 2 wind turbine gearbox 12 is symmetrically fixedly connected with fixed shafts 17 at both ends, and the peripheral surface of the fixed shaft 17 is movably connected with a clamp 18, and the clamp 18 is plugged into the peripheral surface of the fixed column 16; the No. 1 wind turbine gearbox 11 is fixedly connected with an insert block 19 on the side surface, and a slot 121 is provided in the middle of the side surface of the No. 2 wind turbine gearbox 12, and the insert block 19 is plugged into the slot 121.

[0024] Working principle: When the wind turbine gearbox with an impact protection structure is subjected to impact force, the protection plate 21 is subjected to the impact force and will transfer the force to the shock-absorbing spring 22. The shock-absorbing spring 22 is subjected to the impact force and thus undergoes elastic deformation, thereby buffering the impact force, thereby preventing the wind turbine gearbox mechanism 1 from being subjected to the impact force and causing deformation and damage. When the wind turbine gearbox mechanism 1 needs to be disassembled, it is only necessary to apply a rotational force to the clamp 18 so that the clamp 18 does not contact the fixed column 16, and then apply an outward pulling force to the outer wind turbine gearbox No. 1 11 and the wind turbine gearbox No. 2 12 respectively, so that the wind turbine gearbox mechanism 1 can be disassembled. Otherwise, the wind turbine gearbox mechanism 1 can be installed, which makes it easier to inspect and repair the wind turbine gearbox mechanism 1. It is relatively convenient and practical, and is worthy of promotion.
