[0002] Wind turbine blade grinding equipment is a mechanical tool specially used to process the surface of wind turbine blades to improve their performance. With the rapid development of the wind power industry, the quality requirements for wind turbine blades are getting higher and higher. Due to the large size and complex curved surface of wind turbine blades, the traditional manual grinding method is not only inefficient, but also produces a lot of dust, which is harmful to the health of workers. At the same time, if the wind turbine blade grinding device does not have the ability to swing, it may affect the uniformity of grinding, increase the risk of blade damage, reduce operational flexibility, reduce efficiency, increase maintenance costs and increase health risks. Secondly, a lot of heat will be generated during the grinding process. If it is not cooled down in time, the high temperature may cause the performance of the blade material to decline, and even cause deformation, cracking and other damage. Therefore, based on the above problems, this application document proposes a wind turbine blade grinding device to improve the above problems. Utility Model Content

[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0023] like Figure 1 and Figure 5 As shown, a wind turbine blade grinding device includes a frame 10, a moving mechanism 18 is assembled at the upper end of the frame 10, a support plate 14 is arranged at the upper end of the moving mechanism 18, a telescopic motor 16 and a water tank 17 are fixed to the upper end of the support plate 14 from one side to the other side in sequence, a bottom plate 20 is fixed to the bottom end of the telescopic motor 16, a third motor 21 is fixed to the upper end of the bottom plate 20, a driving gear 22 is fixed to the output end of the third motor 21, and the driving gear 22 is located at one end of the bottom plate 20, one end of the bottom plate 20 and one end close to the driving gear 22 is rotatably connected to a driven gear 23, and the driving gear 22 and the driven gear 23 are meshingly connected, a swing rod 24 is fixed to the upper end of the bottom plate 20 and located at the upper end of the driven gear 23, a fourth motor 25 is fixed to one end of the driven gear 23 and located at the bottom end of the swing rod 24, a grinding disc 26 is fixed to the output end of the fourth motor 25, and a shield 27 is fixed to the outer side of the fourth motor 25.

[0024] like Figure 2 and Figure 3As shown, the moving mechanism 18 includes a first slide rail 11, a first motor 12, a second slide rail 13 and a second motor 15. The two first slide rails 11 are slidably connected to both sides of the upper end of the frame 10, the first motor 12 is fixed to one side of a first slide rail 11, the two second slide rails 13 are fixed to the upper end of the first slide rail 11, the support plate 14 is slidably connected to the upper ends of the two second slide rails 13, and the second motor 15 is fixed to the support plate 14 and one end close to the telescopic motor 16.

[0025] like Figure 5 As shown, the material of the shield 27 is transparent rubber. The shield 27 can prevent flying debris or dust from injuring the operator, thereby improving work safety. At the same time, the shield 27 helps to limit the splashing of these particles, maintain the cleanliness of the working environment, and avoid contamination of other equipment or processes. At the same time, it can be deformed during polishing and can quickly return to its original shape after the external force is removed, which enables the rubber shield 27 to effectively absorb and alleviate impact force.

[0026] like Figure 3 and Figure 4 As shown, a plurality of fixing columns 30 are fixed to the bottom end of the support plate 14, a fixing plate 31 is fixed to the bottom ends of the plurality of fixing columns 30, a water pump 32 is fixed to the upper end of the fixing plate 31 and located at the bottom end of the support plate 14, and the water pump 32 and the water tank 17 as well as the water pump 32 and the protective cover 27 are connected via a conduit 33.

[0027] Furthermore, the conduit 33 is a bellows, and the corrugated structure of the bellows provides good elasticity and deformability, so that it can adapt to different degrees of deformation and pressure, and is suitable for various expansions or movements. Secondly, the bellows is non-conductive and has good sealing properties, which can prevent stray current corrosion and improve the fatigue resistance of the component.

[0028] Furthermore, the water tank 17 is made of a transparent material. The water tank 17 is transparent so that the flow of the liquid and the water level can be observed intuitively, which helps to promptly detect any abnormalities, such as a low water level. At the same time, the water tank 17 allows the user to directly observe the state of the water quality, including color, turbidity, etc., and promptly detect foreign objects in the water.

[0029] The working principle of the utility model is:

[0030] When the blades of the wind turbine generator need to be polished, the first motor 12 can drive the first slide rail 11 to move, and the second motor 15 can drive the second slide rail 13 to move. When the blades are moved to the position where polishing is required, the telescopic motor 16 is extended downward. Because the bottom plate 20 is fixed to the lower end of the telescopic motor 16, and the third motor 21 is fixed to the upper end of the bottom plate 20, when polishing the plane, the third motor 21 stops, and the fourth motor 25 starts to rotate. The polishing disc 26 is fixed to the output end of the fourth motor 25 and starts to rotate, thereby The blades of the wind turbine are ground. When the blades are ground into a curved surface, the third motor 21 starts to rotate slowly, the third motor 21 drives the driving gear 22 to rotate, and the driving gear 22 drives the driven gear 23 to rotate. Because the fourth motor 25 is fixed on the driven gear 23, and the swing rod 24 is fixed to one end of the base plate 20, the fourth motor 25 starts to rotate, and the grinding disc 26 also starts to rotate. When cooling is required, the water pump 32 draws water from the water tank 17 through the conduit 33 to the shield 27, thereby cooling the blades of the wind turbine.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
