Description

[0002] During the operation of wind power generation equipment, a corresponding water cooling system is required for cooling. Referring to a wind turbine water cooling device (CN209586601U), the device includes a frame with a water tank inside. A miniature water pump is installed inside the water tank, and a water pipe is installed on one side of the miniature water pump. When the water temperature in the tank rises due to the heat generated by the generator, external wind carries away the heat from the tank through ventilation openings, preventing the temperature inside the tank from rising further. This facilitates continuous cooling of the generator by the water in the tank. However, as described in the aforementioned patent, existing water cooling systems for wind-cooled units are ineffective when the water temperature in the tank is too high and the external temperature is also high. The time required to interrupt and replace the cooling water is too long, affecting the water cooling efficiency of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] refer to Figure 1-4 This utility model provides the following two technical solutions:

[0026] First embodiment: A water cooling system for a wind turbine with automatic liquid addition includes a housing 1. The housing 1 is connected to a cooling component for water cooling of the wind turbine. The cooling component includes: an iron core 2, disposed inside the housing 1 for heat absorption by the wind turbine; a cooling pipe 3, installed inside the housing 1 and wound around the outside of the iron core 2 for water cooling heat absorption; a water storage component 4, installed at the bottom of the housing 1 for water cooling by the automatic liquid addition mechanism. The water storage component 4 includes a water storage shell 41 for storing water and installed at the bottom of the housing 1. The water storage shell 41 has a built-in liquid level sensor 44 for detecting the water level. A water cooling component 45 for supplying water to the cooling pipe 3 for cooling is installed on the rear side of the water storage shell 41; a filter 5, installed on the water storage shell 41 for collecting and filtering rainwater; and a protective shell 6, installed on the rear side of the housing 1 for providing protection to the outside of the water cooling component 45. The water storage component 4 also includes a heat sink 42 installed on the outside of the water storage shell 41 for heat dissipation. A drain valve 43 is installed at the bottom of the water storage shell 41, and a drain pipe is provided at the bottom of the drain valve 43.

[0027] The water-cooled component 45 includes a water pump 451 installed on the rear side of the water storage shell 41 for supplying water. The water pump 451 has a first three-way valve 452 installed at the pumping end for switching the pumping direction. A first pumping pipe 453 for drawing external water is provided on the right side of the first three-way valve 452. A second pumping pipe 454 for drawing water from the water storage shell 41 is installed below the first three-way valve 452. A water injection pipe 455 fixedly connected to and communicating with the cooling pipe 3 is installed on the upper side of the first three-way valve 452. A drain pipe 456 for draining is installed on the left side of the cooling pipe 3. A second three-way valve 457 for switching the draining direction is installed near the inner side of the protective shell 6 on the drain pipe 456. A return pipe 458 fixedly connected to the upper rear side of the water storage shell 41 is provided on the lower side of the second three-way valve 457. A water tank 459 for replenishing water to the water storage shell 41 is installed on the right side of the second three-way valve 457.

[0028] The second pumping pipe 454 is fixedly connected to and communicates with the water storage shell 41. A water supply valve is installed on the front side of the water tank 459 and fixedly connected to the lower rear end of the water storage shell 41. The water tank 459 is installed inside the protective shell 6. The water pump 451, the first three-way valve 452, the first pumping pipe 453, and the second pumping pipe 454 cooperate with each other to adjust the pumping direction. The guide pipe 456 cooperates with the second three-way valve 457 and the return pipe 458 to adjust the drainage direction. The water tank 459 cooperates with the drain valve 43 to facilitate the discharge and replenishment of water stored in the water storage shell 41, thereby improving the water cooling efficiency.

[0029] The main difference between the second implementation method and the first implementation method is that:

[0030] The filter element 5 includes a receiving shell 51 installed on the upper left side of the water storage shell 41. The upper side of the receiving shell 51 is provided with a filter tank with an internal filter plate 52 for filtering rainwater. The upper side of the filter plate 52 is attached with an auger 53 for retaining and discharging impurities. The protective shell 6 is provided with a motor 54 for driving the auger 53. The drain valve 43, liquid level sensor 44, water pump 451, first three-way valve 452, second three-way valve 457, motor 54, and water supply valve are all electrically connected to an external controller.

[0031] The receiving shell 51 is connected to the water storage shell 41. The filter plate 52 is an arc-shaped plate and its surface is attached to the blade end of the auger 53. The output end of the motor 54 is coaxially and fixedly connected to the auger 53. When the receiving shell 51 receives rainwater from the outside to replenish the water storage shell 41, the filter plate 52 filters solid impurities, allowing the motor 54 to drive the auger 53 to rotate. The rotating auger 53 removes the impurities retained on the filter plate 52.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] In use, the user covers the iron core 2 inside the housing 1 to the outside of the wind turbine, and installs the entire device at the end of the wind turbine. The drain valve 43, liquid level sensor 44, water pump 451, first three-way valve 452, second three-way valve 457, motor 54, and water supply valve are electrically connected to the external controller. When water cooling is required for the wind turbine, the water pump 451 is started. The water pump 451 draws external water through the first three-way valve 452 and the first water suction pipe 453. Then the water is injected into the cooling pipe 3 through the water injection pipe 455. The wound cooling pipe 3 absorbs the heat dissipated by the iron core 2 and the cooling unit through heat transfer. Then the water flows into the water storage tank 41 through the conduit 456, the second three-way valve 457, and the return pipe 458.

[0034] After the level sensor 44 detects that the water level in the water storage tank 41 has reached a suitable height, it switches the first three-way valve 452. The water pump 451 then pumps water into the water storage tank 41 through the first three-way valve 452 and the second water pipe 454 to achieve water circulation and heat dissipation. The heat sink 42 on the side of the water storage tank 41 dissipates heat from the water inside the tank. On rainy days, rainwater passes through the filter plate 52 and the receiving shell 51 before entering the water storage tank 41. When the water level in the water storage tank 41 is too high, the drain valve 43 is activated, and the drain valve 43 drains the water from the water storage tank. Water in storage tank 41 is discharged to the recycling end through the drain pipe. When the temperature sensor detects that the temperature inside storage tank 41 is continuously higher than the temperature required for cooling, the first three-way valve 452 is reset, and the second three-way valve 457 is reversed. At this time, the water pump 451 continues to pump external water. The water passing through the cooling pipe 3 is introduced into the water tank 459 through the conduit 456 and the second three-way valve 457. At the same time, the drain valve 43 is opened to discharge the high-temperature water in storage tank 41. The water supply valve is opened, and the water tank 459 replenishes water to storage tank 41 through the water supply valve.
