[0020] The following is combined with Figure 1-7 The specific implementation methods of the utility model are further described in detail.

[0021] Embodiment 1, the technical solution is that the present application provides a hydraulic lubrication cooling device for a wind turbine, specifically, a cooling device for a generator 1 in a generator 1 group, specifically, a cooling chamber 3 arranged in a cooling jacket can receive cold water from a water supply device, a heat-conducting copper plate 4 is arranged in the cooling chamber 3, a heat-conducting copper bar 5 abutting against the outer wall of the generator 1 is arranged on the copper plate, the heat-conducting copper bar 5 cooperates with the heat-conducting copper plate 4 to absorb the heat generated by the generator 1, and the cold water in the cooling chamber 3 can exchange heat with the heat absorbed by the heat-conducting copper plate 4 to cool the generator 1, and a spiral guide plate 6 is also arranged in the cooling chamber 3 to increase the travel of the cold water in the cooling chamber 3, thereby ensuring the heat exchange effect between the cold water and the heat-conducting copper plate 4 and the cooling effect. The transit cooling device can receive the cooling water after heat exchange and heating from the cooling chamber 3, and cool it in the cooling barrel 8, and after cooling, it can also be discharged to the water supply device for use, so that the cooling water can be recycled.

[0022] Embodiment 2, on the basis of embodiment 1, specifically, when the generator 1 is working, the heat-conducting copper plate 4 cooperates with the heat-conducting copper bar 5 to continuously absorb heat from the generator 1, and cooling water is stored in the water supply tank 21 of the water supply device. When the generator 1 is working, the water supply valve 24 is opened and the water supply pump 22 is started. The water supply pump 22 transports the cooling water in the water supply tank 21 to the cooling chamber 3 through the water supply pipe 23. The cooling water entering the cooling chamber 3 will spiral downward along the spiral guide plate 6, increasing the travel of the cooling water in the cooling chamber 3, thereby facilitating heat exchange between the cooling water and the heat-conducting copper plate 4, and thereby cooling the generator 1. The temperature of the cooling water after heat exchange between the cooling chamber 3 and the heat-conducting copper plate 4 will increase, and then the cooling water with increased temperature will enter the cooling barrel 8 of the transfer cooling device through the drain pipe 7 for temporary storage.

[0023] In order to quickly cool down the cooling water in the cooling barrel 8 so as to facilitate its delivery to the water supply device for recycling. Specifically, in order to quickly cool down the cooling water from the cooling chamber 3 in the cooling barrel 8, the hydraulic telescopic cylinder 10 on the support plate 9 should be started to perform continuous telescopic action, and the air cooler 12 should also be started. The extension of the hydraulic telescopic cylinder 10 will drive the vertical rod 13 and the copper container 14 to move upward along the axis of the support frame 11 through the connecting rod 16. The copper container 14 will hold a certain amount of cooling water and move upward during the upward process. When the copper container 14 is separated from the liquid surface, the cooling water in the copper container 14 will be thrown downward from the opening 15 to form a thin water curtain. The air cooler 12 can quickly cool down the cooling water by blowing on the water curtain. After that, the hydraulic telescopic cylinder 10 will shrink and drive the copper container 14 to sink to the bottom of the water. As the hydraulic telescopic cylinder 10 continues to expand and contract, the above process will be repeated, thereby quickly cooling down the cooling water in the cooling barrel 8. When necessary, the drain valve 20 of the drain assembly can be opened and the drain pump 18 can be started. Under the action of the drain pump 18, the cooled cooling water can enter the water supply tank 21 through the front conduit 17 and the rear conduit 19 in sequence to facilitate the circulation of the cooling water.

[0024] Embodiment 3, based on embodiment 2, the copper container 14 can absorb the temperature of the cooling water to cool the cooling water, and after the copper container 14 is lifted out of the water surface as the hydraulic telescopic cylinder 10 extends, the air cooler 12 can also cool the copper container.
