Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a device for cleaning copper heat sinks of a wind power generator. Background Art

[0002] Copper heat sinks are a key component in wind turbines, used to dissipate heat and cool the wind turbine. Since wind turbines generate heat during operation, heat sinks are essential to effectively dissipate this heat to maintain acceptable temperatures. Copper heat sinks are a popular choice for wind turbines due to their excellent thermal conductivity and corrosion resistance. They are typically installed on the stator and rotor of a wind turbine to improve heat dissipation and maintain stable temperatures. The design and construction of copper heat sinks can be tailored to the specific needs of the wind turbine. Generally, copper heat sinks feature a scaly or raised surface to maximize surface area and heat dissipation. They also need to work closely with other wind turbine components (such as the cooling fan and heat pipes) to ensure the effective operation of the entire cooling system. Using copper heat sinks can effectively reduce wind turbine operating temperatures, improve efficiency and reliability, and extend service life. Therefore, copper heat sinks hold significant application value in the wind power industry.

[0003] Conventional methods for cleaning the copper radiator of a wind turbine are mostly performed by moving a brush or a scraper up and down. However, during the dust cleaning process, the cleaned dust will still fly around in the air and attach to the copper radiator again. In addition, the floating dust will pollute the surrounding environment, reducing the cleaning efficiency. Summary of the Invention

[0034] Example 1

[0035] Reference Figure 1 - Figure 2 , which is a first embodiment of the present invention, provides a wind turbine copper heat sink cleaning device, comprising a fixing component 100, including a mounting base 101, a fixing frame 102 symmetrically mounted on the mounting base 101, a forward and reverse threaded rod 103 rotatably mounted on the fixing frame 102, a clamping assembly 104 having opposite threads on both sides of the forward and reverse threaded rod 103 and threadedly mounted on the forward and reverse threaded rod 103, and a tilting frame 105 and a collection box 106 disposed on the mounting base 101, wherein the tilting frame 105 is fixedly mounted on the mounting base 101;

[0036] The cleaning component 200 includes a movable frame 201 symmetrically arranged on the mounting base 101, the movable frame 201 is slidably mounted on the top of the mounting base 101, and a limiting member is further provided on the top of the mounting base 101, which can limit the movable frame 201 after it moves toward the copper heat sink, so that it will not move when cleaning the copper heat sink; a screw rod 202 and a servo motor 203 arranged on the movable frame 201, the screw rod 202 is rotatably mounted on the movable frame 201, and one end of one of the screw rods 202 is fixedly connected to the output end of the servo motor 203; a belt 204 and a drainage box 205 are arranged between the two screw rods 202, and the two screw rods 202 are driven by the belt 204, so that the drainage box 205 threadedly mounted between the two screw rods 202 can move up and down; a cleaning component 206 arranged on the drainage box 205, and the copper heat sink is cleaned by the cleaning component 206; and a rotating component 207 and a pulling component 208 used in conjunction with the cleaning component 206; and,

[0037] The pushing component 300 includes a connecting frame 301 fixedly installed at the bottom of the movable frame 201, a baffle 302 and a rotating plate 303 arranged on the connecting frame 301, the rotating plate 303 is rotatably installed on the connecting frame 301, and a scraping component 304 is arranged on the tilting frame 105, and the tilting frame 105 is cleaned by the scraping component 304.

[0038] Specifically, the clamping assembly 104 includes a concave frame 104a threadedly installed on both sides of the forward and reverse screw rods 103, a clamping plate 104b and a first spring 104c symmetrically arranged on the concave frame 104a, the clamping plate 104b is slidably installed on the concave frame 104a, and a guide plate 104d symmetrically arranged on the fixed frame 102.

[0039] Furthermore, the first spring 104c is located between the clamping plate 104b and the concave frame 104a, and the clamping plate 104b can be reset by the first spring 104c. The side of the guide plate 104d close to the clamping plate 104b is set as a slope. The opposite surfaces of the two fixing frames 102 are fixedly connected with square plates and are located directly below the clamping assembly 104. The top end of each positive and negative screw rod 103 passes through the fixing frame 102.

[0040] Operation process: When in use, by rotating the two positive and negative screw rods 103, the concave frame 104a moves toward the opposite side. When the concave frame 104a moves, the clamping plate 104b will gradually contact the inclined surface of the guide plate 104d and squeeze the clamping plate 104b, so that the distance between the two clamping plates 104b gradually increases. At this time, the first spring 104c is squeezed, and then the copper heat sink to be cleaned is placed between the two fixed frames 102 and supported by the square plate so that the two ends of the copper heat sink are located between the clamping plate 104b and the guide plate 104d. At this time, the positive and negative screw rods 103 are rotated in the opposite direction to make the concave frame 104a move to the opposite side and reset. At the same time, the distance between the two clamping plates 104b gradually decreases, and the copper heat sink is clamped and fixed by the reaction force of the first spring 104c (such as Figure 1 or 3).

[0041] Example 2

[0042] Reference Figure 3 - Figure 7 , which is the second embodiment of the present invention. Different from the first embodiment, the cleaning component 206 includes a water storage tank 206a fixedly mounted on the mounting base 101, a water supply pipe 206b connected between the water storage tank 206a and the drainage box 205, and a water pump is also provided on the mounting base 101. The output end of the water pump is connected to the water supply pipe 206b, an atomizing pipe 206c, a brush 206d and a rotating rod 206e are provided on the drainage box 205, and the drainage box 205 and the atomizing pipe 206c are connected. A sponge 206f is sleeved on the rotating rod 206e, a placement groove is provided on the rotating rod 206e, and an arc block 206g and a second spring 206h are provided in the placement groove. The inner wall of the sponge 206f is expanded by the arc block 206g, and the sponge 206f can be fixed on the rotating rod 206e by the expansion force.

[0043] Specifically, the surface of the atomizing tube 206c is connected to a plurality of atomizing nozzles, which can spray water in atomized form. There are a plurality of atomizing tubes 206c, brushes 206d and rotating rods 206e, which are arranged equidistantly. A hard mounting plate is provided at one end of the sponge 206f close to the drainage box 205. The second spring 206h is located between the arc block 206g and the placement groove, and the arc block 206g is reset by the second spring 206h.

[0044] Furthermore, the rotating assembly 207 includes a first gear 207a fixedly mounted on the surface of the rotating rod 206e, a rack belt 207b arranged between several first gears 207a, and the several first gears 207a are transmitted through the rack belt 207b, a second gear 207c fixedly mounted on the surface of one of the rotating rods 206e, a limit block 207d slidably mounted on the surface of the drainage box 205 and close to the side of the second gear 207c, and a rack 207e fixedly mounted on the collection box 106.

[0045] Furthermore, one end of the limit block 207d is engaged with the second gear 207c to limit the second gear 207c so that it does not rotate. A fourth spring is fixedly connected between the other end of the limit block 207d and the drainage box 205, and the limit block 207d can be reset by the fourth spring. The rack 207e is located directly below the second gear 207c, and there is a gap between the sponge 206f and the second gear 207c. The second gear 207c is a flywheel.

[0046] Furthermore, the pulling assembly 208 includes a box body 208a and a long plate 208b arranged between the two fixing frames 102, the size of the long plate 208b is consistent with the size of the gap between the sponge 206f and the second gear 207c, and a pull rod 208c fixedly installed at both ends of the long plate 208b.

[0047] The rest of the structure is the same as that of Example 1.

[0048] Operation process: push the movable racks 201 on both sides to move toward the copper heat sink, and limit the movable racks 201 through the limiter on the top of the mounting base 101. At this time, the atomizing tube 206c, the brush 206d and the sponge 206f will be located directly above the copper heat sink, and then start the servo motor 203 to drive one of the screw rods 202 to rotate, and the belt 204 drives the drainage box 205 to start to descend. At the same time, the water pump will also start to work, allowing the water pipe 206b to transport the water in the water tank 206a to the drainage box 205, and then the water will enter the atomizing tube 206c and be sprayed to the gap between the copper heat sinks through the atomizing nozzle on the surface, so that the dust on the surface will not splash due to the water. At this time, as the drainage box 205 As the drain box 205 continues to descend, the atomizing tube 206c, the brush 206d and the sponge 206f will descend, and the dust in the interval will be swept down first by the brush 206d, and then wiped by the sponge 206f. The dust swept down will increase in weight due to the water, and will eventually fall onto the tilt frame 105 and slide into the collection box 106 for collection. As the drain box 205 continues to descend, the atomizing tube 206c, the brush 206d and the sponge 206f will descend to the bottom of the copper heat sink and no longer contact the copper heat sink. At this time, one side of the rack 207e will first contact the limit block 207d, and squeeze the limit block 207d to move it, and release the limit on the second gear 207c. At this time, the second gear 207c will mesh with the rack 207e, and as it descends, the second gear 207c will rotate 90 degrees, so that the gear connected to it The rotating rod 206e rotates, and through the transmission of the rack belt 207b, the first gear 207a also drives the other rotating rods 206e to rotate, causing the sponge 206f to rotate 90 degrees, so that the clean two sides correspond to the interval between the copper heat sinks, and then the servo motor 203 drives the screw rod 202 to rotate in the opposite direction, so that the drainage box 205 rises. At this time, water no longer enters the drainage box 205, and the second gear 207c is a flywheel, so that even if the second gear 207c engages with the rack 207e when rising, it will not drive the rotating rod 206e to rotate. The second gear 207c will only idle on the surface of the rotating rod 206e at this time. After separating from the rack 207e, the reaction force of the fourth spring causes the limit block 207d to reset and engage with the second gear again. The wheel 207c is engaged to limit it, and the copper heat sink interval is cleaned twice by the clean sponge 206f and the brush 206d, thereby improving the cleaning effect. After the drainage box 205 rises to the top, the long plate 208b will be located between the sponge 206f and the second gear 207c. Then the pull rod 208c is pulled to move the long plate 208b and squeeze the sponge 206f, so that several sponges 206f can quickly separate from the rotating rod 206e and fall into the box body 208a. Then the clean sponge 206f is installed on the rotating rod 206e again. During the installation, the arc block 206g is squeezed by the hard mounting plate, so that the arc block 206g moves toward the depth of the rotating rod 206e. After the installation is completed,The second spring 206h allows the arc block 206g to return to its original position, expanding the inner wall of the sponge 206f. This expansion force secures the sponge 206f to the rotating rod 206e. The movable frames 201 on both sides are then pushed back to their original positions, and the long plate 208b is then reset. Finally, the clamping assembly 104 is released from securing the copper heat sink. The cleaned copper heat sink can then be removed. Repeat the above steps for the remaining copper heat sink.

[0049] Example 3

[0050] Reference Figure 8 - Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that the scraping assembly 304 includes a slide groove 304a symmetrically opened on both sides of the tilting frame 105, an L-shaped plate 304b and a third spring 304c arranged in the slide groove 304a, the L-shaped plate 304b is slidably installed in the slide groove 304a, and a scraper 304d is fixedly installed between the two L-shaped plates 304b.

[0051] Specifically, the top surface of the tilting frame 105 is set to be an inclined surface, the slide groove 304a is set to be inclined, the bottom end of the scraper 304d is in contact with the top inclined surface of the tilting frame 105, and a torsion spring is provided at one end of the rotating plate 303. When the movable frame 201 moves toward the copper heat sink, it will also drive the connecting frame 301 to move. At this time, the rotating plate 303 will contact the L-shaped plate 304b, and the rotating plate 303 will be squeezed to rotate. After separating from the L-shaped plate 304b, it is reset by the torsion spring.

[0052] The rest of the structure is the same as that of Example 2.

[0053] Operation process: When the movable frame 201 is pushed backward to reset, the connecting frame 301 will also move with it. At this time, the rotating plate 303 will contact the L-shaped plate 304b. The baffle 302 will block the rotating plate 303 from rotating and squeeze the L-shaped plate 304b, so that it drives the scraper 304d to move toward the lower part of the inclined surface at the top of the inclined frame 105. The scraper 304d scrapes off the impurities remaining on the top of the inclined frame 105 and pushes it into the collection box 106 for storage. Since the slide groove 304a is inclined, the L-shaped plate 304b will gradually separate from the rotating plate 303 during movement, and finally reset by the third spring 304c.
