[0002] A wind turbine is a device that uses wind power to drive the generator rotor to rotate, thereby converting wind energy into electrical energy. In order to prevent the equipment from overheating and causing performance degradation or damage, a cooling device is required to cool and dissipate heat. Through effective heat dissipation, the cooling device can extend the service life of the generator, improve power generation efficiency, and ensure the stable operation of the entire wind power generation system.

[0038] Working process: The energy-saving air-water cooling equipment performs the cooling operation on the wind turbine as follows. Note 1: The cooling electrical appliances of this equipment are all powered by the power supply 8 and are all controlled by the control box 7; Note 2: The cooling process of the cooling water by the refrigeration unit 5 is as follows. When the low-temperature and low-pressure refrigerant liquid passes through the expansion throttle valve, it undergoes a throttling process, and the pressure is reduced, causing the refrigerant to expand and evaporate rapidly in the evaporator, absorbing the heat transferred by the cooling water, causing the cooling water temperature to drop, and achieving a refrigeration effect. The evaporated refrigerant gas is sucked in and compressed by the compressor, and the pressure and temperature increase. Then, the high-temperature and high-pressure refrigerant gas enters the condenser, releasing heat to the surrounding environment, and the refrigerant condenses into a high-pressure liquid. Finally, the high-pressure liquid is refrigerated. The agent enters the evaporator again through the expansion throttle valve, and the cycle continues, thereby continuously refrigerating the cooling water; Note 3: The cooling water of this equipment is driven by the liquid pump 68, and is drawn out from the evaporator of the refrigeration unit 5 through the liquid outlet pipe 67, and then passes through the heat exchange coil 66, the liquid supply pipe 69, the upper connecting pipe 463, the upper cavity of the bypass folded pipe 462, and the left folded hose 461 to enter the heat exchange folded pipe 435 for circulation, completing the first half of the cycle, and then the cooling water enters the right folded hose 461 from the other end of the heat exchange folded pipe 435, passes through the lower cavity of the bypass folded pipe 462, the lower connecting pipe 463 to enter the return pipe 65, and the cooling water is returned to the evaporator through the return pipe 65, completing the whole cooling water cycle;Air cooling operation steps: the main generator 15 and the gear box 14 of the wind turbine will generate temperature during operation, which will cause the temperature in the cabin 12 to continue to rise. In order to stabilize the room temperature of the cabin 12, the exhaust fan 62 is first started to exhaust air from the frame shell 2 that carries and accommodates the main generator 15 and the gear box 14 through the exhaust pipe 63. The extracted hot air flow will be sent to the partition plate 61 and contact the heat exchange air duct 101. At the same time, since the cabin 12 of the wind turbine is in a high-altitude and windy environment, the air guide 103 installed at the cabin 12 can guide the wind in all directions downward into the heat exchange air duct 101. In the process of the air flow passing through the heat exchange air duct 101, the heat exchange air duct 101 exchanges heat with the hot air flow entering the partition plate 61, so that the wind passing through the heat exchange air duct 101 takes away the heat of the hot air flow in the partition plate 61, reduces the temperature of the air flow that has undergone heat exchange in the partition plate 61, and then the low-temperature air flow after heat exchange It will enter the air cavity 23 of the seat plate 21 through the air outlet pipes 64 on both sides and be discharged from the air outlet holes 24, so that the low-temperature airflow after heat exchange moves upward to take away the heat emitted by the gear box 14 and the generator host 15, and then is drawn into the exhaust pipe 63 to complete an air cooling cycle. In this way, the temperature of the gear box 14 and the generator host 15 can be effectively controlled to avoid overheating. When the water cooling is started, the hot air flow in the partition plate 61 can also exchange heat with the circulating cooling water through the heat exchange coil 66 (the cooling water will usually increase by 5-6° after heat exchange, and subsequent local water cooling operations can still be carried out), further reducing the air flow temperature after heat exchange and improving the air cooling effect on the gear box 14 and the generator host 15. The air cooling operation is completed through the above steps, so that the energy-saving air-water cooling equipment can prevent external dust and corrosive gases from entering the cabin and affecting the service life of the unit when air cooling the key equipment of the wind turbine;The local water cooling operation steps are as follows: the temperature is detected by the temperature sensors 9 at various positions. When the gear box 14 and the generator host 15 have a local temperature that is too high and exceeds the threshold during operation, the temperature sensor 9 at the corresponding local high temperature position sends an electrical signal to the control box 7, so that the control box 7 determines the high temperature position according to the information of the temperature sensor 9, and then controls the adjustment part 3 to adjust the position of the water cooling device 4. The operation of the angle adjustment motor 34 is controlled to drive the gear roller 32 and the guide rod 33 to rotate, and the gear roller 32 is meshed with the inner gear frame 31, so that the rotating gear roller 32 drives the entire adjustment part 3 and the water cooling device 4 to move at the arc frame of the arc guide plate 25, completing the angle adjustment of the water cooling device 4, and then the horizontal adjustment motor 37 is controlled to operate, so that the rotation of the screw rod 38 drives the screw rod 38 to rotate with it. The spirally connected wire guide sleeve 39 is displaced on the guide rod 33, and the displacement of the wire guide sleeve 39 will drive the water cooling device 4 to move (so that the connecting pipe 463 is translated in the hole position of the right rail plate 29 according to the movement of the water cooling device 4). Through the above operation, the water cooling device 4 is moved to the local high temperature position. After the position adjustment is completed, the angle adjustment motor 34 and the horizontal adjustment motor 37 are controlled to stop, and the preparation operation of local water cooling is completed. At this time, the refrigeration unit 5 is started to cool the cooling water in the evaporator, the liquid pump 68 is started to circulate the cooling water, and then the air pump of the air delivery component 45 is started to inflate the base shell 41, so that the contact part 43 moves outward with the air pressure, so that the thermal conductive silicone pad 433 of the contact part 43 is in elastic and full contact with the local high temperature of the gear box 14 or the generator host 15. As the contact part 43 moves, the folded hose 461 will unfold and extend to ensure the normal circulation of cooling water; the heat at the local high temperature of the gear box 14 or the generator host 15 will be conducted to the heat conducting plate 432 through the thermal silicone pad 433, and then dispersed to each thermal fin 434 to exchange heat with the cooling water circulation in the heat exchange folded tube 435, so that the cooling water takes away the heat in the circulation. After cooling, the air delivery component 45 is controlled to deflate, and the contact part 43 is driven to reset by the tension spring 44, and then the refrigeration unit 5, the liquid pump 68 and the air pump of the air delivery component 45 are controlled to stop, and the local water cooling operation is completed through the above steps; in summary, the cooling operation of this equipment is divided into three states: normal cooling measures, maintaining the cabin 12, the gear box 14 and the generator host 15 through air cooling The temperature of the main engine 15, in this state, only the exhaust fan 62 is started; local cooling measures, when the local high temperature of the equipment exceeds the threshold, the local high temperature position of the equipment is locally water-cooled for a short time (the water cooling time can be set as needed). In this state, the angle adjustment motor 34, the horizontal adjustment motor 37, the air pump of the gas transmission component 45, the liquid pump 68 and the refrigeration unit 5 will be started for a short time when needed, and it is in a shutdown state outside the state; equipment overload cooling measures, when the equipment is overloaded and the overall high temperature appears, the cooling water circulation is started to improve the air cooling efficiency of the equipment and perform more effective temperature control; the energy-saving air-water cooling equipment can be adaptively carried out normal, local, overload processing and other targeted cooling measures according to the temperature conditions of the key equipment of the wind turbine. ;
