The first valve block 200 is connected to the first water outlet 110, and the first valve block 200 has an air-cooling connection port 210, and the air-cooling connection port 210 is used to connect an external air cooler. The expansion tank 300 is in communication with the first valve block 200. The second valve block 400 is connected to the second water outlet 120, and the second valve block 400 has a first connection port 410 thereon, and the first connection port 410 is used for connecting a water cooling pipeline inside the generator.

In this embodiment, the water pump assembly 100 can circulate the cooling medium through the water cooling pipeline inside the generator, thereby reducing the operating temperature of the generator. The air-cooling connector 210 on the first valve block 200 can be connected with an external air cooler, so that when the temperature of the cooling medium rises, the temperature of the cooling medium is timely reduced, and the working effect of the cooling system is ensured. In this embodiment, the number of air-cooled connecting holes is two, and two air coolers can be connected simultaneously, so that the speed of reducing the temperature of the cooling medium is increased. The cooling medium in the cooling system can also exchange heat with hydraulic oil in a hydraulic pipeline of the gearbox in the plate heat exchanger 500, so that the aim of reducing the temperature of the hydraulic oil of the gearbox is fulfilled. In this embodiment, the expansion tank 300 has a volume of 25L and a pre-charge nitrogen pressure of 1.5bar, and mainly functions to convert the pressure energy into elastic potential energy for storage and to maintain the pressure at the outlet of the water pump unit 100 stable. By utilizing one set of cooling system, the purpose of simultaneously reducing the internal temperature of the wind motor 130 and the temperature of a hydraulic pipeline of the gear box can be realized, the structure is compact, the reliability is high, and the cost is saved.
In consideration of the safety problem of the internal pressure of the cooling system, the cooling system for the wind generating set further includes a safety valve 220 and a water collection bottle 230, the safety valve 220 is mounted on the first valve block 200, and a water outlet of the safety valve 220 is connected to the water collection bottle 230. When the pressure in the cooling system is too high, the cooling medium can flow out of the water collecting bottle 230 through the safety valve 220, so that the safety of the cooling system is ensured. In this embodiment, the set value is 5bar for controlling the pressure of the whole cooling system, and when the pressure exceeds 5bar, the safety valve 220 is actuated, and the cooling medium overflows to stabilize the system pressure.
In addition, the cooling system for the wind generating set further comprises a water replenishing valve 240, and the water replenishing valve 240 is installed on the first valve block 200.

When the system normally works, the water replenishing valve 240 is normally closed, and when the system needs to be filled with cooling medium, the water replenishing ball valve is opened to replenish the cooling medium into the system pipe through external power. When the system needs quick pressure relief, the pressure relief can be realized by opening the water-filled ball valve.
In this embodiment, the cooling system of the wind turbine generator system further includes a filter screen 250, and the filter screen 250 is installed on a pipeline connecting the first water outlet 110 and the first valve block 200.
