Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically to a cooling water filtration and sterilization device. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of a rotor, generator (including the generator assembly), directional control unit (tail fin), tower, speed limiting safety mechanism, and energy storage device. The wind turbine cooling system is a crucial system for ensuring effective heat dissipation and maintaining stable temperatures for all components during operation.

[0003] A search revealed prior art publication number CN212178548U, which discloses a water supply device for a wind turbine generator converter water cooling system. The device includes a coolant tank, a water pump M2, a solenoid valve V2, a check valve N, a pressure sensor PT2, and a converter water cooling system. The coolant tank, water pump M2, solenoid valve V2, and check valve N are connected sequentially along a supply pipeline. The check valve N is connected to the converter water cooling system and faces the system. The pressure sensor PT2 is located on the supply pipeline between the check valve N and the solenoid valve V2. By utilizing the spare space at the wind turbine tower base to install a water tank and supply water to the water cooling system, the cooling water system pressure is maintained constant, preventing wind turbine shutdown due to low pressure and improving the availability and economic efficiency of the wind turbine.

[0004] After prolonged operation, the cooling water in the existing wind turbine generator cooling device contains various impurities, and bacteria also grow in the cooling water. The growth of bacteria in the cooling device leads to a reduction in the cooling effect. Therefore, based on the above research and in light of the existing problems, a cooling water filtration and sterilization device is provided. Utility Model Content

[0005] The purpose of this invention is to provide a cooling water filtration and sterilization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling water filtration and sterilization device includes a wind turbine generator, a generator fixedly installed at the upper end of the wind turbine generator, and blades fixedly installed on the rotating end of the generator generator.

A water outlet block is fixedly installed at the water outlet end of the cooling shell, and a water outlet pipe is fixedly installed at the lower end of the water outlet block. A water storage tank is fixedly installed at the end of the water outlet pipe away from the water outlet block, and the water storage tank is fixedly installed at the upper end of the wind turbine generator.

[0009] Furthermore, a water pump is fixedly installed at the bottom of the inner wall of the water storage tank, a water transmission pipe is fixedly installed at the outlet of the water pump, a disinfection pipe is fixedly connected to the upper end of the water transmission pipe, and the end of the water inlet pipe away from the water inlet block is fixedly connected to the upper end of the disinfection pipe.

The lower end of the cooler will wrap around the disinfection pipe, and the control end of the cooler is provided with a control line for controlling the working efficiency of the cooler.

[0010] Furthermore, the filtration and disinfection mechanism includes a germicidal lamp, which is fixedly installed at the upper end of the disinfection tube. A filter box is fixedly installed at the input end of the water pump, and the filter box passes through the side end of the water storage tank. A filter frame is slidably installed at the end of the filter box away from the water pump, and multiple layers of filter screens are fixedly installed on the inner wall of the filter frame.

[0011] Furthermore, a resistance rod is fixedly connected to the end of the control line away from the cooler, and the resistance rod is fixedly installed on the inner wall of the water inlet block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a filter screen in the filter box to filter out impurities.

[0025] 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.

[0026] Example: Please refer to Figures 1-4A cooling water filtration and sterilization device includes a wind turbine generator 1, a generator 102 fixedly installed on the upper end of the wind turbine generator 1, and blades 101 fixedly installed on the rotating end of the generator 102. When the blades 101 rotate, the generator 102 starts to generate electricity. A cooling mechanism 2 for cooling the generator 102 is sleeved on the outer wall of the generator 102. A filtration and sterilization mechanism 3 for filtering, disinfecting and sterilizing the cooling water is provided in the cooling mechanism 2.

[0027] Please see Figures 1-3 The cooling mechanism 2 includes a cooling shell 201, which wraps around the outer wall of the generator 102 to cool it down. A water inlet block 202 is fixedly installed at the water inlet end of the cooling shell 201, and a water inlet pipe 203 is fixedly installed at the upper end of the water inlet block 202. A water outlet block 210 is fixedly installed at the water outlet end of the cooling shell 201, and a water outlet pipe 211 is fixedly installed at the lower end of the water outlet block 210. A water storage tank 204 is fixedly installed at the end of the water outlet pipe 211 away from the water outlet block 210, and the water storage tank 204 is fixedly installed at the upper end of the wind turbine generator 1. When the generator 102... When the temperature of generator 102 begins to rise, cooling water is transferred to the cooling shell 201 through the inlet pipe 203 and the inlet block 202, and then discharged back to the storage tank 204 through the outlet block 210 and the outlet pipe 211, thereby cooling the generator 102. A collection pipe 207 is fixedly installed at the upper end of the storage tank 204, and a one-way valve is provided between the collection pipe 207 and the storage tank 204. A collection hopper 205 is fixedly installed at the upper end of the collection pipe 207, and a protective net 206 is provided at the upper end of the collection hopper 205. When it rains, rainwater is collected, thereby playing a role in energy saving and environmental protection.

[0028] Please see Figures 1-3A water pump 212 is fixedly installed at the bottom of the inner wall of the water storage tank 204. A water transmission pipe 213 is fixedly installed at the outlet of the water pump 212. A disinfection pipe 214 is fixedly connected to the upper end of the water transmission pipe 213. The disinfection pipe 214 is made of a transparent pipe material as used in the prior art. The disinfection pipe 214 is fixedly installed on the inner wall of the water storage tank 204. The end of the water inlet pipe 203 away from the water inlet block 202 is fixedly connected to the upper end of the disinfection pipe 214. A cooling box 208 is fixedly installed on the outer wall of the disinfection pipe 214 away from the water transmission pipe 213. A cooler 209 is fixedly installed at the upper end of the cooling box 208. The lower end of the cooler 209 will wrap around the disinfection pipe 214. The cooler 209 is a cooler as used in the prior art. The cooling device has a cooling pipe at its cooling end, which wraps around the disinfection pipe 214. When the cooler 209 starts working, it cools the disinfection pipe 214. Specifically, when it is necessary to cool the generator 102, the water pump 212 is turned on, so that the water in the water tank 204 is transferred to the disinfection pipe 214 through the water transfer pipe 213 for cooling and disinfection. Then, the water is transferred to the cooling shell 201 through the water inlet pipe 203 and the water inlet block 202 to cool the generator 102. The control end of the cooler 209 is equipped with a control line 4 for controlling the working efficiency of the cooler 209. The control line 4 controls the output power of the cooler 209, thereby controlling the temperature of the cooling water transferred to the cooling shell 201 through the disinfection pipe 214.

[0029] Please see Figures 1-3 The filtration and disinfection mechanism 3 includes a germicidal lamp 301, which is a conventional ultraviolet disinfection lamp, and will not be described in detail here. The germicidal lamp 301 is fixedly installed at the upper end of the disinfection tube 214. The disinfection tube 214 is a transparent pipe, allowing ultraviolet rays to penetrate the disinfection tube 214 and irradiate the cooling water in the water storage tank 204 when the germicidal lamp 301 disinfects the cooling water in the disinfection tube 214. This ensures that the disinfection of the cooling water is both rapid and comprehensive. A filter box 302 is fixedly installed at the input end of the water pump 212, and the filter box 302 passes through the water storage tank 204. On the side, a filter frame 303 is slidably installed at the end of the filter box 302 away from the water pump 212, and a sealing ring is provided on the side of the filter frame 303 near the filter box 302, so that the filter box 302 and the filter frame 303 remain sealed when the filter frame 303 is installed inside the filter box 302. Multiple layers of filter screens 304 are fixedly installed on the inner wall of the filter frame 303. Specifically, when the generator 102 needs to be cooled, the water pump 212 is started, so that the water in the water storage tank 204 is filtered through the filter screens 304 set in the filter box 302 to filter out impurities. The filtered cooling water is transferred to the disinfection pipe 214 through the water transmission pipe 213, and the sterilization lamp 301 is turned on to disinfect the cooling water.

[0030] Please see Figures 1-4 A resistance rod 405 is fixedly connected to one end of the control line 4 away from the cooler 209, and the resistance rod 405 is fixedly installed on the inner wall of the water inlet block 202. A detection cylinder 401 is fixedly installed on the side end of the water inlet block 202, and the detection cylinder 401 is located inside the generator 102. The detection cylinder 401 is filled with nitrogen gas that is easily expanded by heat, so that when the temperature in the generator 102 changes, the gas pressure in the detection cylinder 401 changes rapidly.

[0031] Please see Figures 1-4 A piston ring 402 is slidably disposed on the inner wall of the detection cylinder 401 near the water inlet block 202. A piston rod 403 is fixedly installed at the end of the piston ring 402 away from the detection cylinder 401. A brush block 404 is fixedly installed at the end of the piston rod 403 away from the piston ring 402, and the brush block 404 slides against the outer wall of the resistance rod 405. Specifically, when the temperature of the generator 102 begins to rise, the nitrogen gas in the detection cylinder 401 begins to expand, pushing the piston ring 402 to move. The piston ring 402 pushes the piston rod 403, and the piston rod 403 drives the brush block 404 to slide on the surface of the resistance rod 405. The output voltage of the control line 4 increases, causing the output cooling power of the cooler 209 to increase, thereby lowering the temperature of the cooling water entering the cooling shell 201, so that the cooling device controls the temperature of the generator 102 within a suitable range.

[0032] Working principle: When the wind turbine 1 starts working, the temperature of the generator 102 begins to increase. The water pump 212 is turned on, causing the water in the storage tank 204 to pass through the filter screen 304 in the filter box 302 to filter impurities. The filtered cooling water is then transferred through the water pipe 213 to the disinfection pipe 214. At the same time, the germicidal lamp 301 disinfects the cooling water and also disinfects the cooling water in the storage tank 204, thus making the disinfection of the cooling water faster and more comprehensive.

[0033] After disinfection and sterilization, the cooling water is transferred to the disinfection pipe 214 through the water transfer pipe 213 for cooling and disinfection, and then transferred to the cooling shell 201 through the water inlet pipe 203 and the water inlet block 202. Finally, it is discharged back to the water storage tank 204 through the water outlet block 210 and the water outlet pipe 211, thereby cooling the generator 102.

[0034] At the same time, when the temperature of generator 102 begins to rise, the nitrogen in the detection cylinder 401 begins to expand, and the piston rod 403 drives the brush block 404 to slide on the surface of the resistance rod 405, causing the output cooling power of the cooler 209 to increase, thereby lowering the temperature of the cooling water entering the cooling shell 201, so that the cooling device controls the temperature of generator 102 within a suitable range, preventing generator 102 from being damaged due to temperature rise.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
