Description

Technical Field

[0001] The invention relates to the technical field of liquid cooling devices, and in particular to a liquid cooling device for a wind turbine generator set. Background Art

[0002] A liquid cooling device is a thermal management system that efficiently transfers the heat generated by equipment operation to the external environment through the circulation of liquid medium. Its core goal is to maintain equipment operation within a safe temperature range to avoid performance degradation or damage due to overheating. Liquid cooling devices are widely used. When a wind turbine is working, a liquid cooling device is used to dissipate heat from structures such as the gearbox inside the wind turbine.

[0003] At present, when the existing liquid cooling device is in use, scale will be generated inside the coolant. Although the scale can be filtered out by filtering equipment, due to the high working position of the liquid cooling device, the staff may only clean the scale once a year or two. Therefore, the scale will accumulate on the inner wall of the pipeline and the filtering equipment, causing pipeline congestion, resulting in low heat conversion efficiency, and easily leading to a decrease in heat dissipation efficiency.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing wind turbine liquid cooling devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0045] The specific implementation of this embodiment is as follows: when it is necessary to process the scale accumulated in the scale filter cloth 221, the first stepper motor 212 is controlled to operate, and the operation of the first stepper motor 212 will drive the first threaded shaft 215 to rotate, and the threaded connection relationship between the first threaded shaft 215 and the first rectangular plate 216 can be used to drive the first rectangular plate 216 and the fixed frame 222 to move to the right, until the first rectangular plate 216 and the fixed frame 222 move to the rear of the rectangular box 217.

[0046] Example 2: Please refer to Figure 6-Figure 12 The present invention provides a technical solution: a liquid cooling device for a wind turbine.

The pipeline port processing mechanism 3 includes a cleaning unit 31, and the cleaning unit 31 is arranged in front of the condensation box 1. The cleaning unit 31 can effectively remove scale on the inner wall of the pipeline that reduces the thermal conductivity.

[0047] As a further limitation of the pipe port processing mechanism 3 of the present invention, the cleaning unit 31 includes a second rectangular plate 3108, the bottom surface of the second rectangular plate 3108 is fixedly connected to the third rectangular plate 3107, the front surface of the third rectangular plate 3107 is fixedly connected to the spiral cylinder 3115, the interior of the spiral cylinder 3115 and the interior of the third rectangular plate 3107 are slidably connected to the spiral shaft 3105, the interior of the spiral shaft 3105 is slidably connected to the long shaft 3104, the end of the long shaft 3104 away from the second stepper motor 202 is fixedly connected to the extrusion block 3117, the inner wall of the spiral shaft 3105 is fixedly connected to the first return spring 3120, the interior of the spiral shaft 3105 is slidably connected to two scrapers 3114, the inner wall of the spiral shaft 3105 is fixedly connected to two groups of connecting plates 3116, and the interior of the spiral shaft 3105 is provided with three groups of transmission plates 31 18. Each second return spring 3119 is fixedly connected to a side surface of the spiral shaft 3105 that is close to the circle, the inner wall of the condensation box 1 is rotatably connected to the third threaded shaft 3101, the outer surface of the third threaded shaft 3101 is fixedly connected to the first steering gear 3102, the outer surface of the first steering gear 3102 is meshed with the second steering gear 3103, the outer surface of the third threaded shaft 3101 is threadedly connected to the moving cylinder 3111, the inner wall of the moving cylinder 3111 is rotatably connected to the rotating sleeve 3109, the inner wall of the rotating sleeve 3109 is fixedly connected to the ferrite magnet 3113, and by setting the cleaning unit 31, the cleaning unit 31 can be used to effectively deal with the scale accumulated at the pipe mouth, so as to prevent the scale from accumulating in large quantities at the connection between the pipe mouth and the filter cloth, resulting in a decrease in water flow, thereby reducing the thermal conductivity.

[0048] See also Fig.12 The inner wall of each scraper 3114 is rotatably connected to the roller 3106, the outer surface of each roller 3106 contacts the outer surface of the extrusion block 3117, the inner wall of the second rectangular plate 3108 is threadedly connected to the outer surface of the first threaded shaft 215, the upper surface of the second rectangular plate 3108 contacts the inner top wall of the condensation box 1, and the end of the first return spring 3120 close to the long axis 3104 is fixedly connected to the inner wall of the extrusion block 3117. The number of each group of transmission plates 3118 is two. By providing the scraper 3114, the scraper 3114 can be used to treat the scale on the inner wall of the circulation pipe 3205.

[0049] See also Figure 7A rectangular frame 3110 is fixedly connected to the left side of the rectangular box 217, and a sliding block 3112 is slidably connected inside the rectangular frame 3110. The outer surface of the sliding block 3112 is fixedly connected to the outer surface of the moving cylinder 3111, wherein the side surfaces of two transmission plates 3118 close to each other are respectively fixedly connected to the two side surfaces of one of the scrapers 3114, and the side surfaces of the other four transmission plates 3118 close to each other are respectively fixedly connected to the two side surfaces of another scraper 3114, one end of each second return spring 3119 is fixedly connected to the side surface of the connecting plate 3116 close to the center of the spiral shaft 3105, and the inner wall of the second steering gear 3103 is fixedly connected to the outer surface of the second rotating shaft 218. By providing the sliding block 3112 and utilizing the characteristic of the sliding block 3112 sliding inside the rectangular frame 3110, the rotation of the moving cylinder 3111 can be avoided.

[0050] The specific implementation of this embodiment is as follows: when the first stepper motor 212 is running, it will drive the threaded shaft to rotate, and the threaded connection relationship between the threaded shaft and the first rectangular plate 216 will drive the first rectangular plate 216 and the fixed frame 222 to move to the right to the final position, and the second rectangular plate 3108 threadedly connected to the surface of the first threaded shaft 215 will also move to the right, thereby driving the third rectangular plate 3107 to move to the right, so that the third rectangular plate 3107 moves to the front of the circulation tube 3205. At this time, the spiral shaft 3105 sliding inside the third rectangular plate 3107 will be just in front of the center of the circulation tube 3205. When the second stepper motor 202 is running, the second stepper motor 202 will drive the second rotating shaft 218 and the second steering gear. 3103 rotates, and the rotation of the second steering gear 3103 can transmit power to the first steering gear 3102, which can further drive the third threaded shaft 3101 to rotate. By utilizing the threaded connection between the third threaded shaft 3101 and the moving cylinder 3111, the rotating sleeve 3109 and the ferrite magnet 3113 can be pushed to move toward the position of the long axis 3104, so that the ferrite magnet 3113 is magnetically connected to one end of the long axis 3104. As the third threaded shaft 3101 continues to rotate, the moving cylinder 3111 will push the spiral shaft 3105 to move toward the inside of the circulation pipe 3205. However, when the spiral shaft 3105 moves toward the inside of the circulation pipe 3205, the spiral groove on the surface of the spiral shaft 3105 is fixed to the inner wall of the spiral cylinder 3115. 3105 moves toward the direction of the circulation tube 3205 while rotating. Since the ferrite magnet 3113 is magnetically connected to the long axis 3104, the rotational power generated when the spiral shaft 3105 rotates will also be transmitted to the ferrite magnet 3113 and the rotating sleeve 3109. However, the rotating sleeve 3109 rotates on the inner wall of the moving cylinder 3111. Therefore, the rotational connection between the rotating sleeve 3109 and the moving cylinder 3111 can be used to offset the rotational power, so that the moving cylinder 3111 can move laterally normally. When the long axis 3104 is pushed by the thrust to push the spiral shaft 3105 to move inside the circulation tube 3205, the second stepper motor 202 will run in the reverse direction. After a series of force transmission, the final It will eventually drive the moving cylinder 3111, the rotating sleeve 3109 and the ferrite magnet 3113 to move in the opposite direction, so that the long shaft 3104 and the extrusion block 3117 can be pulled forward first, and the extrusion block 3117 will squeeze the two scrapers 3114 to move outward, so that the scrapers 3114 contact the inner wall of the circulation tube 3205. It should be understood here that the contact surface between the third rectangular plate 3107 and the spiral shaft 3105 is covered with a layer of rubber, so the friction coefficient between the two is large. Therefore, when the second stepper motor 202 runs in the reverse direction, the converted reverse pulling force will first act on the long shaft 3104, and the long shaft 3104 will pull the extrusion block 3117 to move forward first, and achieve the purpose of pushing the scraper 3114 to extend outward. It can be understood here thatThe friction between the third rectangular plate 3107 and the spiral shaft 3105 is greater than the friction between the extrusion plate and the scraper 3114. As the long shaft 3104 continues to move forward, the limit plate fixed on the surface of the long shaft 3104 will contact the inner wall of the spiral barrel 3115. Therefore, the long shaft 3104 will transmit power to the spiral shaft 3105, driving the spiral shaft 3105 to move forward synchronously. When the spiral shaft 3105 moves forward, it will still rotate along the spiral strip fixed on the inner wall of the spiral barrel 3115, thereby driving the scraper 3114. 114 rotates and moves forward to take out the scale. As the long shaft 3104 continues to move forward, the scraper 3114 will eventually contact the back of the third rectangular plate 3107. At this time, the long shaft 3104 and the spiral shaft 3105 can no longer move forward until the pulling force is greater than the magnetic force of the ferrite magnet 3113 and the long shaft 3104. At this time, the two will be disconnected, thereby removing the scale accumulated on the inner wall of the circulation pipe 3205, thereby increasing the flow rate of the condensed water. The inner wall of the circulation pipe 3205 can be cleaned many times by repeating the cycle.

[0051] Example 3: Please refer to Figure 8 , Fig. 9 , Fig.13 and Fig.14 The present invention provides a technical solution: a liquid cooling device for a wind turbine. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The pipeline port processing mechanism 3 also includes a centralized processing unit 32, which is arranged at the rear of the condensation box 1. The centralized processing unit 32 cooperates with the cleaning unit 31, and the centralized processing unit 32 can centrally process the cleaned scale.

[0052] As a further limitation of the pipeline port processing mechanism 3 of the present invention, the centralized processing unit 32 includes a collection box 3206, the front of the collection box 3206 is fixedly connected with a force spring 3208, the bottom of the collection box 3206 is movably hinged with a folding plate 3210, the front of the collection box 3206 is fixedly connected with two positioning shafts 3207, the back of the collection box 3206 is fixedly connected with two bull's eye bearings 3209, the back of the condensation box 1 is fixedly connected with a centralized box 3201, and the inner wall of the centralized box 3201 is fixedly connected with a plurality of identical heating wires 321 3. The upper surface of the centralized box 3201 is fixedly connected with a fixed frame 3214, the inner wall of the fixed frame 3214 is fixedly connected with a hydraulic rod 3203, the telescopic end of the hydraulic rod 3203 is fixedly connected with a push plate 3202, and a centralized processing unit 32 is provided, and the collected scale can be centrally processed by the centralized processing unit 32. By providing a filter cloth cleaning mechanism, a cleaning unit 31 and a centralized processing unit 32, it can be effectively avoided that a large amount of scale is generated when the equipment is in use, and the scale will accumulate on the inner wall of the pipe, thereby reducing the heat conduction efficiency.

[0053] See also Fig.14 A second water pump 3212 is fixedly connected to the back of the condensation tank 1, and a second water pumping pipe 3204 is fixedly connected to the input end of the second water pump 3212. The end of the second water pumping pipe 3204 close to the condensation tank 1 passes through the condensation tank 1 and extends to the interior of the condensation tank 1. The output end of the second water pump 3212 is fixedly connected to the second drain pipe 3211. A circulation pipe 3205 is fixedly connected to the back of the condensation tank 1. One end of the force spring 3208 is fixedly connected to the inner wall of the third rectangular plate 3107. The bottom surface of the folding plate 3210 contacts the inner wall of the condensation tank 1. The outer surface of each positioning shaft 3207 is slidably connected to the interior of the third rectangular plate 3107. By providing the second water pump 3212, the condensed water can be pumped out by using the second water pump 3212 and the second water pumping pipe 3204, and the gear box and other equipment are cooled and then returned to the interior of the condensation tank 1 through the circulation pipe 3205.

[0054] The specific implementation of this embodiment is as follows: when the scale in the scale filter cloth 221 is processed, the cleaning water and the scale will enter the interior of the collection box 3201 along the guide plate 224, and when the third rectangular plate 3107 moves to the right, the collection box 3206 fixed on the back of the third rectangular plate 3107 will also move to the right synchronously, so that the cleaned scale will enter the interior of the collection box 3206. When the scale is cleaned, the first stepper motor 212 runs to drive the first threaded shaft 215 to rotate in the opposite direction, which can drive the collection box 3206 to return to its original position. When the collection box 3206 is reset, there is no obstruction behind the collection box 3206, so the collection box 3206 will move backward under the action of the force spring 3208. When the folding plate 3210 movably hinged on the bottom surface of 206 moves to the top of the collecting box 3201, the folding plate 3210 will fold downward, so that the scale collected inside the collecting box 3206 will enter the interior of the collecting box 3201. When the equipment needs to be controlled to process the scale again, it is necessary to first control the hydraulic rod 3203 to push the push plate 3202 to move, and use the push plate 3202 to push the collecting box 3206 to move inside the condensation box 1, so that the collecting box 3206 can follow the third rectangular plate 3107 to move to the right, and then the heating wire 3213 can be controlled to operate, and the heat generated by the heating wire 3213 during operation is used to heat the water and scale mixture, so that the water can evaporate, leaving only the scale inside the collecting box 3201, thereby increasing the scale storage capacity.
