[0002] With the improvement of infrastructure construction and renewable energy facilities in my country, wind turbines have been widely used. Wind turbines are a green power generation device that converts mechanical energy into electrical energy.

[0003] At present, the waste oil channel on the wind turbine tower is difficult to clean manually due to the small space. In addition, the waste oil has low fluidity and strong adhesion, so the waste oil pipe or wire used to clean the waste oil channel is very inconvenient. On the other hand, waste oil easily forms solid grease blocks when it comes into contact with air, and in extremely cold areas, the grease is prone to solidification and freezing, so it is difficult to effectively clean the waste oil channel.

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] refer to Figure 1~Figure 3 The utility model protects a waste oil treatment device for a wind turbine generator, comprising a housing 13 and a motion unit; the motion unit comprises a driving member 1, an elastic member 4 and a pounding block 10; the pounding block 10 contracts and rebounds while rotating in the housing 13; the pounding block 10 is coupled to the elastic member 4 through a thrust bearing 12, and the driving member 1 is movably connected to the pounding block 10 through a shaft sleeve device.

[0022] By providing the elastic member 4, the elastic member 4 is allowed to accumulate force during the upward rotation of the pounding block 10. When the arc-shaped raised track 5 on the pounding block 10 is no longer in contact with the fixed block 11, that is, two arc-shaped raised tracks 5 are provided, and there is a space between the two for the fixed block 11 to slide, the elastic member 4 releases the elastic force to eject the pounding block 10 downward. By providing the thrust bearing 12, the elastic member 4 and the pounding block 10 can be coupled while allowing relative rotation. This structure has the characteristics of small structure and strong rebound.

[0023] refer to Figure 1~Figure 3 In a specific embodiment, the sleeve device includes a power output shaft 2 of a driving member 1 and a power input shaft 3 of a pounding block 10. The end of the power input shaft 3 of the pounding block 10 is a "cross-shaped" cylindrical protrusion 14, and the end of the power output shaft 2 of the driving member 1 is a "circular tube" shape. Four long strip holes 15 are symmetrically arranged at the end of the power output shaft 2, and the diameter of the long strip holes 15 is the same as the diameter of the "cross-shaped" cylindrical protrusion 14; the four ends of the "cross-shaped" cylindrical protrusion 14 on the power input shaft 3 of the pounding block 10 are inserted into the four long strip holes 15 of the power output shaft 2 of the driving member 1.

[0024] By cooperating with each other, the power output shaft 2 of the driving member 1 and the power input shaft 3 of the pounding block 10, the power of the driving member 1 can be stably transmitted to the pounding block 10, while allowing axial relative movement between the pounding block 10 and the driving member 1. The structure of the device is relatively simple and suitable for narrow working spaces.

[0025] refer to Figure 1~Figure 3 In a specific embodiment, a water inlet 16 is provided on the upper portion of the shell 13 , and a fixing block 11 is provided on the inner wall of the shell 13 opposite to the water inlet 16 .

[0026] By providing the water inlet 16, hot water can be introduced into the device to melt the solidified grease and clean the residual grease on the circular hanging plate 9 of the pounding block 10. This method can efficiently clean the grease solidified at low temperature.

[0027] refer to Figure 1~Figure 3 In a specific embodiment, the fixing block 11 is cylindrical.

[0028] By providing the cylindrical fixing block 11, the friction between the fixing block 11 and the arc-shaped raised track 5 can be reduced, the pounding block 10 can rotate more smoothly, and the service life of the device is increased.

[0029] refer to Figure 1~Figure 3 In a specific embodiment, two relatively parallel arc-shaped raised tracks 5 are provided on the outer surface of the pounding block 10 , and the upper surface of the arc-shaped raised track 5 is in sliding contact with the outer surface of the fixed block 11 , and the arc-shaped raised track 5 rotates against the fixed block 11 .

[0030] By providing two arc-shaped raised tracks 5, the pounding block 10 can rotate, shrink and automatically rebound under the action of the fixed block 11 and the arc-shaped raised tracks 5. The device has an ingenious structure and reduces the size of the device.

[0031] refer to Figure 1~Figure 3 In a specific embodiment, a circular hanging plate 9 is provided at the lower end of the outer surface of the pounding block 10 , and the outer diameter of the circular hanging plate 9 is the same as the outer diameter of the shell 13 .

[0032] By setting a circular hanging plate 9 with the same outer diameter, the waste oil attached to the waste oil channel can be cleaned. At the same time, the shell 13 of the wind turbine waste oil treatment device is in contact with the inner wall of the waste oil channel. When the outer wall and the grease inside the waste oil channel are cleaned by the circular hanging plate 9, the shell 13 will fall under the action of gravity and continue to clean the deeper waste grease in the waste oil channel. This device does not require manual operation and can automatically clean the waste oil in the waste oil channel, which is labor-saving and convenient.

[0033] refer to Figure 1~Figure 3 In a specific embodiment, the outer edge of the circular hanging plate 9 has a circle of raised blades with a "right triangle" cross-section, and five blades 8 are cross-arranged on the lower surface of the circular hanging plate 9, and 10 through holes are evenly arranged between the blades 8.

[0034] By setting a raised blade in the shape of a "right triangle", the grease sticking on the inner wall of the waste oil channel can be scraped off. By cross-setting five blades 8 on the lower surface of the circular hanging plate 9, the grease clogged in the waste oil channel can be scraped off. By setting a through hole 6, the hot water entering the device from the water inlet 16 can be discharged from the water outlet 6 to melt the condensed waste grease, making it easy to be scraped off by the scraper 8, and the grease fragments scraped off the circular hanging plate 9 can also be cleaned. After scraping off the grease sticking on the inner wall of the waste oil channel, the waste oil channel can be flushed by flushing methods such as an external water pump, so that the grease scraped off the inner wall of the waste oil channel is flushed to the outside.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
