Description

Technical Field

[0001] The present application relates to the technical field of wind turbine generator equipment, and specifically discloses a wind turbine generator heat sink cleaning device. Background Art

[0002] With the promotion of new energy projects, wind turbines have become one of the main energy supply methods in some areas of modern society. Wind turbines convert wind energy into electrical energy through the action of blades and motors, and then store it or directly transmit it to electrical appliances.

[0003] At present, wind turbines may have the following problems when working for a long time: gearbox low-speed shaft out of limit, high gearbox cooling water temperature, high generator cooling water temperature and high gearbox oil temperature. The main cause of these failures is the heat sink at the bottom of the generator gearbox. During long-term operation, dust accumulates and causes blockage, which in turn leads to a decrease in the heat dissipation capacity of the cooling system. Every time the water temperature is too high, manual cleaning of the heat sink is required with a flushing pump.

[0004] The patent with authorization announcement number CN216044204U discloses a wind turbine heat sink cleaning device, which uses an electric slide to drive a brush to clean the heat sink at the bottom of the generator gear box. However, during long-term use of the brush, the brush will gradually wear against the heat sink, resulting in a shortening of the brush length. In addition, when cleaning, the brush directly contacts the dust accumulated on the heat sink. Since the brush is elastic, when the heat sink with a gap moves, when it moves from the plate to the gap, or from the gap to the plate, the brush will shake due to the elasticity, and at this time, the dust adhering to the heat sink will be bounced into the generator gear box, causing internal dust accumulation, thereby affecting the operation of the components in the gear box.

[0005] Therefore, in view of this, the inventor provides a wind turbine heat sink cleaning device to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that a conventional cleaning device for a radiator plate of a wind turbine may shake dust into a gear box of the wind turbine during cleaning due to the elasticity of the brush installed on the cleaning device.

[0009] The cleaning member includes an upper cleaning plate arranged between two sliders on both sides, a water sprayer arranged on the inner side of the upper cleaning plate and connected to the water outlet pump, and a lower cleaning plate arranged at the bottom of the upper cleaning member and used to recover water flow. The upper cleaning plate and the lower cleaning plate are respectively arranged on both sides of the heat dissipation plate, and both end surfaces of the upper cleaning plate and the lower cleaning plate are provided with bosses that fit with the end surfaces of the heat dissipation plate, and the bosses are provided with cleaning pads. A connecting block for mounting the lower cleaning plate is provided at one end of the bottom of the upper cleaning plate, and a slide groove for sliding the connecting block is provided on the gear box;

[0010] The end surfaces of the lower cleaning plate wrap the end surfaces of the upper cleaning plate, and the lower cleaning plate is provided with an inclined groove for water flow to flow in. The bottom of the inclined groove is sealed with a sealing baffle, and a return hose is connected between the sealing baffle and the water inlet pump.

[0011] Furthermore, the boss end surfaces on both sides of the lower cleaning plate are also provided with fine-flesh brushes, and the fine-flesh brushes are all arranged on the inner side of the cleaning pad layer.

[0012] Furthermore, the cleaning pad layer is a rubber pad layer, and both sides of the rubber pad layer are provided with rounded corners for transition.

[0013] Furthermore, the sprinkler includes a main pipe connected to the water outlet pump at one end and auxiliary pipes arranged on both sides of the main pipe. The free ends of the main pipe and the auxiliary pipe are both closed, and the main pipe and the auxiliary pipe are both provided with a plurality of high-pressure water outlets.

[0014] Furthermore, the high-pressure water outlets on the auxiliary pipes on both sides are staggered.

[0015] Furthermore, the high-pressure water outlets each include a plurality of circular holes distributed circumferentially.

[0016] Furthermore, the auxiliary pipe can swing back and forth on both sides of the main pipe, a rack is provided in the gear box along the direction of movement of the slider, and a gear transmission mechanism meshing with the rack and used for transmission and a crank slider mechanism driven by the gear transmission mechanism to drive the auxiliary pipe to swing are provided in the upper cleaning plate.

[0017] Furthermore, a water outlet is provided at the top of the water outlet chamber of the collecting tank, and a water supply hose for connecting to a sprinkler is connected to the water outlet. A telescopic plate for accommodating the water supply hose is provided in the gear box.

[0018] Furthermore, the telescopic plate includes a guide plate and a slide plate slidably connected to the guide plate. A movable groove is provided in the guide plate for the slide plate to slide and extend. A spring is provided in the movable groove.

[0019] Further, the upper cleaning plate is provided with a liquid pump in communication with the water supply hose and used for pressurization, and the liquid outlet of the liquid pump is in communication with the water sprayer.

[0020] The principle and effect of the basic scheme are that:

[0021] 1. Before using the present application, water is first injected into the liquid collecting tank, and then it is put into use. During use, the sliding blocks are driven to slide by the electric sliding rails, and the upper and lower cleaning plates are synchronously driven to slide on the two end faces of the heat dissipation plate by the synchronous sliding of the sliding blocks on the two sides. The rubber pad layers on the two sides of the upper and lower cleaning plates are respectively attached to the end faces of the heat dissipation plate, and the inclined table is located outside the contact table and partially overlaps the rubber pad layer. The fine lint brush on the inclined table is arranged below the rubber pad layer of the contact table. The fine lint brush can fall some dust, and the wrapped and closed upper and lower cleaning plates will not cause dust and water mist to fly.

[0022] 2. With the continuous and repeated movement of the sliding blocks, the water sprayer in the upper cleaning plate will suck water from the liquid collecting tank through the water pump and pump the water into the main pipe and the auxiliary pipe. The high-pressure water flow is formed by the pressure given by the liquid pump and is sprayed out of the high-pressure water outlets on the main pipe and the auxiliary pipe to the heat dissipation plate to clean the heat dissipation plate. The water mist formed on the heat dissipation plate and the sprayed water curtain will be wrapped in the upper and lower cleaning plates and will drip down or be swept into the inclined chute of the lower cleaning plate through the rubber pad layer, and then will be collected into the sealing baffle and then be introduced into the liquid collecting tank by the water inlet pump. The water is filtered by the filter layer in the liquid collecting tank to realize repeated use and sewage purification.

[0023] 3. During the movement of the upper cleaning plate, the gear transmission mechanism is engaged with the rack to drive the two auxiliary pipes to swing through the internal gear transmission and the cooperation with the crank slider mechanism, which will increase the cleaning angle of the cleaning plate and form a swinging water curtain to increase the cleaning area and cleaning strength.

[0024] The present application cleans the heat dissipation plate by high-pressure water curtain, realizes the reuse of water resources by the reflux hose, the water supply hose and the liquid collecting tank, realizes cleaning by the main pipe and the auxiliary pipe, and prevents dust and water mist from overflowing into the gear box by the wrapped upper and lower cleaning plate structure, which solves the problem of the traditional wind turbine heat dissipation plate cleaning device. The brush installed on the cleaning device has elasticity, and when cleaning, the dust will be shaken into the gear box of the wind turbine. BRIEF DESCRIPTION OF DRAWINGS

[0033] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0034] The figure marks in the drawings of the specification include: gear box 1, liquid collecting tank 2, return hose 3, positioning ring 4, water supply hose 5, slide plate 6, slider 7, electric slide rail 8, heat sink 9, upper cleaning plate 10, lower cleaning plate 11, liquid pump 12, first adapter plate 13, connecting block 14, rack 15, fine-nose brush 16, lower rubber pad 17, upper rubber pad 18, auxiliary pipe 19, main pipe 20, driving gear 21, driven gear 22, and driven block 23.

[0035] A wind turbine radiator plate cleaning device, for example Figure 1As shown:

[0036] In this embodiment, only the gearbox 1 of the wind turbine and the interior of the gearbox 1 are shown. A circular hole for mounting a functional component is provided on the right side of the gearbox 1. A positioning ring 4 for positioning and mounting the functional component is installed on the right inner wall of the gearbox 1. The positioning ring 4 has four bolt holes circumferentially formed thereon.

[0037] At the bottom of the gear box 1, there is a heat dissipation hole, in which a heat dissipation plate 9 is installed. The heat dissipation plate 9 has a plurality of mesh holes for ventilation, and the heat dissipation plate 9 is fixed in the heat dissipation hole by bolts.

[0038] A guide rail mounting frame is installed on the bottom of each side of the gear box 1. Through the two guide rail mounting frames, an electric slide rail 8 is installed on the bottom of each side of the gear box 1. The guide rail mounting frames on both sides are arranged in parallel. At the same time, the electric slide rails 8 on both sides are also arranged in parallel. A slider 7 is also installed inside the electric slide rails 8 on both sides. The slider 7 can slide on the electric slide rails 8.

[0039] A group of cleaning members are also installed between the sliders 7 on both sides.

[0040] like Figure 1 As shown, a liquid collection tank 2 is mounted behind the gearbox 1. The liquid collection tank 2 is connected to the cleaning unit via two pipes. These two pipes, namely a water supply hose 5 and a return hose 3, respectively, provide water supply and return. In this embodiment, both the water supply hose 5 and the return hose 3 are flexible pipes.

[0041] like Figure 2 As shown, a rack 15 is mounted on the inner bottom surface of the right side of the gearbox 1. The rack 15 is parallel to the electric slide rail 8 and is located on the inner bottom surface of the gearbox 1 inside the electric slide rail 8. At the same time, a chute is opened on the inner bottom surface between the rack 15 and the inner wall of the right side of the gearbox 1. The chute runs through the inner bottom surface of the gearbox 1 and is parallel to the electric slide rail 8.

[0042] like Figure 2 、 Figure 3 and Figure 4 As shown, the cleaning unit includes an upper cleaning plate 10 mounted between the two side sliders 7 above the heat sink 9, a lower cleaning plate 11 mounted below the heat sink 9, an adapter plate mounted inside the two side sliders 7 and used to fix the upper cleaning plate 10, and a water sprayer mounted inside the upper cleaning plate 10. A rack 15 is mounted below the right end of the upper cleaning plate 10.

[0043] In this embodiment, the right adapter plate is the first adapter plate 13, and the left adapter plate is the second adapter plate. The second adapter plate is mounted only on the inside of the slider 7 and is used to mount and position the upper cleaning plate 10. The first adapter plate 13 is mounted on the inside of the slider 7, with the top of the first adapter plate 13 bent to the right and having a water inlet. The bottom of the first adapter plate 13 has a water outlet, and the first adapter plate 13 between the water inlet and the water outlet has a cavity for water flow. A liquid pump 12 is mounted at the bottom of the first adapter plate 13. The liquid inlet of the liquid pump 12 is connected to the water outlet of the first adapter plate 13, and the liquid outlet of the liquid pump 12 is connected to the water sprayer. The upper cleaning plate 10 is mounted below the liquid pump 12 and moves synchronously with the liquid pump 12, the first adapter plate 13, and the slider 7.

[0044] like Figure 3 As shown, a connecting block 14 is installed below the slider 7 on the right. The top of the connecting block 14 extends outward to form a transfer platform, which is connected to the bottom end of the slider 7. The connecting block 14 is placed in the slide groove and can move synchronously with the slider 7 in the slide groove.

[0045] The bottom end of the connecting block 14 is located below the heat sink 9, and the lower cleaning plate 11 is installed on the inner side of the bottom end of the connecting block 14. The lower cleaning plate 11 and the upper cleaning plate 10 have the same width and are arranged opposite to each other up and down, and the length of the lower cleaning plate 11 is longer than the length of the upper cleaning plate 10.

[0046] like Figure 5 and Figure 6 As shown, in this embodiment, the sprinkler includes a main pipe 20 and auxiliary pipes 19 mounted on either side of the main pipe 20. Both the main pipe 20 and the auxiliary pipe 19 are parallel to the upper cleaning plate 10 and extend from the right end bottom surface to the left end bottom surface of the upper cleaning plate 10, but with gaps between them and the right and left end surfaces of the upper cleaning plate 10. The right ends of the main pipe 20 and the auxiliary pipe 19 serve as water inlets, while the left ends of the main pipe 20 and the auxiliary pipe 19 are sealed. The water inlets of both the main pipe 20 and the auxiliary pipe 19 are connected to the liquid outlet of the liquid pump 12. The main pipe 20 and the auxiliary pipe 19 also have a number of high-pressure water outlets equidistantly spaced along the axis. In this embodiment, the high-pressure water outlets of the auxiliary pipes 19 on both sides are staggered. Water pumped in by the liquid pump 12 is sprayed through the high-pressure water outlets onto the heat sink 9 below.

[0047] The lower surface of the upper cleaning plate 10 features a receiving groove for the water sprayer. Chamfers are located between the inner walls and the inner top surface of each side of the receiving groove. In this embodiment, the auxiliary pipes 19 are mounted on these chamfers and can rotate synchronously on either side of the receiving groove. The two auxiliary pipes 19 rotate at the same angle but in opposite directions. The main pipe 20 is fixedly mounted on the inner top surface of the receiving groove.

[0048] A rectangular chamber is provided at the right end portion of the upper cleaning plate 10 , in which a set of drive components for transmitting and driving the auxiliary pipe 19 to rotate is installed, and the bottom of the rectangular chamber passes through the bottom surface of the right end portion of the upper cleaning plate 10 .

[0049] The drive assembly consists of a set of gear transmission mechanisms and two sets of crank slider mechanisms. The gear transmission mechanism provides power for the crank slider mechanism. Figure 6 As shown, the gear transmission mechanism includes a main shaft mounted and rotatable within a rectangular chamber, a driving gear 21 coaxially connected to the main shaft, driven shafts mounted on both sides of the main shaft and rotatable on the inner side of the chamfer, driven wheels coaxially connected to the driven shafts, a right primary gear meshing with both the right driven gear 22 and the driving gear 21, a left primary gear and a left secondary gear meshing with the left driven gear 22 and the driving gear 21, respectively, and the left primary gear and the left secondary gear also meshing with each other. The bottom of the driving gear 21 is located outside the rectangular chamber and meshes with the rack 15 at the bottom of the rectangular chamber.

[0050] Each slider-crank mechanism consists of a rotatable positioning shaft mounted within a rectangular cavity on the inside of the chamfer; rockers coaxially connected to the positioning shaft; cranks coaxially connected to the driven shaft; and a driven block 23 mounted at the end of the crank for rotation. The driven block 23 has a guide groove through which the rocker passes and slides. A through groove is formed in the chamfer, through which the rocker extends and is fixedly connected to the inside of the auxiliary pipe 19.

[0051] As slider 7 drives the upper and lower connecting plates to slide, the driving gear 21 rotates due to the meshing relationship between the racks 15, which in turn drives the left and right gear trains, and in turn the driven gears 22 on each side. Because the number of gears in the gear trains differs by one, the driven gears 22 on each side rotate in opposite directions, but at the same speed. The rotation of the driven gear 22 drives the driven shaft and the crank coaxially connected to the driven shaft. This, in turn, drives the rocker through the slider-crank mechanism, which in turn drives the auxiliary pipe 19 at the end of the rocker to swing. Because the rockers on both sides swing in opposite directions, the auxiliary pipe 19 also swings in opposite directions. As slider 7 continues to move, the auxiliary pipe 19 repeatedly swings inward or outward simultaneously, forming a cross-shaped water curtain. Simultaneously, high-pressure water is supplied by the liquid pump 12 to powerfully flush the heat sink 9 panels impacted by the water curtain, increasing the flushing area and coverage. At the same time, the staggered high-pressure water outlets on the auxiliary pipes 19 will not cause the water curtains on both sides to impact each other and weaken the impact force of the water.

[0052] like Figure 5As shown, contact pads are located on both sides of the lower surface of the upper cleaning plate 10, contacting the heat sink 9. A water sprayer is positioned between the two contact pads. A cleaning pad is mounted on the lower surface of each contact pad, contacting the upper end surface of the heat sink 9. In this embodiment, the cleaning pad is a rubber pad with rounded edges on both sides. Mounted on the contact pads is the upper rubber pad 18.

[0053] The lower cleaning plate 11 is installed below the heat sink 9 and opposite to the upper cleaning plate 10. On both sides of the lower cleaning plate 11, there are inclined platforms tilted outwards, and the top end surfaces of the inclined platforms are also in contact with the heat sink 9. Figure 5 As shown, the inclined platforms on both sides of the lower cleaning plate 11 wrap around the contact platforms on both sides of the upper cleaning plate 10, and a set of cleaning pads are installed on the outside of the inclined platforms, that is, rubber pads are installed, and the edges on both sides of the rubber pads are also rounded. Installed on the inclined platform is the lower rubber pad 17. A set of fine-hair brushes 16 are also installed on the end face of the inclined platform inside the rubber pad. The fine-hair brushes 16 are not elastic, and at the same time, the upper rubber pad is pressed on top of the fine-hair brushes 16. Through the wrapped inclined platform and the rubber pad that fits the heat sink 9, the high-pressure water sprayed by the main pipe 20 and the auxiliary pipe 19, the generated water mist and the water stains attached to the heat sink 9 can all be sealed and wiped off through the rubber pad to the lower cleaning plate 11 below.

[0054] The lower cleaning plate 11, located between the two ramps, is also equipped with a flow channel through which the water flows. The right end of the flow channel is higher than the left end, and the flow channel decreases slowly and smoothly from right to left. A sealing baffle is installed on the left side of the lower cleaning plate 11, completely enclosing the left end of the lower cleaning plate 11. The top end of the sealing baffle and the right end of the lower cleaning plate 11 are both in contact with the bottom surface of the gearbox 1 and can slide on the bottom surface of the gearbox 1.

[0055] On the sealing baffle, there is also a liquid outlet trough connected to the lower cleaning plate 11, such as Figure 1 As shown, on the outside of the sealing baffle, a return hose 3 mounted on the liquid collection tank 2 communicates with the liquid outlet trough. When the sealing baffle moves with the lower cleaning plate 11, it also moves the return hose 3. Because the return hose 3 is a flexible tube, and in this embodiment, its length is longer than the width of the bottom of the gearbox 1, the movement of the sealing baffle does not cause the return hose 3 to be stretched or deformed.

[0056] like Figure 7 and Figure 1As shown, the liquid collection tank 2 includes a water inlet chamber, a water purification chamber, and a water outlet chamber. The water inlet chamber is located on the left side of the liquid collection tank 2, the water outlet chamber is located on the right side of the liquid collection tank 2, and the water purification chamber is located in the middle of the liquid collection tank 2. The top end of the water purification chamber is connected to the water inlet chamber, and the bottom end is connected to the water outlet chamber.

[0057] A water inlet pump is installed at the bottom of the water inlet chamber, and the water inlet pump is used to pump the water in the return hose 3 into the water inlet chamber and then pump it into the clean water chamber.

[0058] A filter layer is installed within the water purification chamber to purify and store water. The internal filter layer is replaceable. After purification, the water is discharged into the connection with the water outlet chamber below. A water outlet pump is also installed at the connection between the water outlet chamber and the water purification chamber. This pumps out the purified water and supplies it through the water supply hose 5, via the first adapter plate 13, to the liquid pump 12. The clean water is then sprayed out through the main pipe 20 and the auxiliary pipe 19.

[0059] like Figure 1 As shown, the water supply hose 5 is also a flexible hose, and a through-hole is provided in the gearbox 1 to allow the water supply hose 5 to pass through. A set of telescopic plates is also installed within the gearbox 1 to accommodate the water supply hose 5. The telescopic plates comprise a guide plate and a slide plate 6. The guide plate has a movable groove that accommodates the slide plate 6 and allows it to slide and extend. The top end of the movable groove has an integrally formed ring, and the bottom end of the slide plate 6 has an integrally formed retaining plate that prevents the retaining plate from extending beyond the ring. A spring is installed within the movable groove to propel the slide plate 6 upward to its highest point, where the retaining plate and the ring abut against each other. The water supply hose 5 is mounted on the top of the slide plate 6. As the slider 7 moves away, it pulls the water supply hose 5 and forces it downward, causing it to extend. When the slider 7 retracts, the slide plate 6 is reset by the spring, which in turn drives the water supply hose 5 back. The telescopic plates prevent the water supply hose 5 from swinging around and potentially affecting the functional components within the gearbox 1.

[0060] Before using the present invention, water is first poured into the liquid collecting tank 2, and then the present invention is put into use. During use, the slider 7 is driven by the electric slide rail 8 to slide, and the sliders 7 on both sides slide synchronously to drive the upper cleaning plate 10 and the lower cleaning plate 11 to slide synchronously on the two end surfaces of the heat dissipation plate 9, and the rubber pads on the end surfaces of the contact platform and the inclined platform on both sides of the upper cleaning plate 10 and the lower cleaning plate 11 are respectively in contact with the end surfaces of the heat dissipation plate 9, and the inclined platform is located outside the contact platform and the rubber pads are partially overlapped, and the fine-hair brush 16 on the inclined platform is arranged below the rubber pad of the contact platform;

[0061] As the slider 7 continues to move repeatedly, the water sprayer in the upper cleaning plate 10 will absorb water from the liquid collection tank 2 through the liquid pump 12, and pump the water into the main pipe 20 and the auxiliary pipe 19. The pressure based on the liquid pump 12 forms a high-pressure water flow, and is sprayed onto the heat sink 9 through the high-pressure water outlets on the main pipe 20 and the auxiliary pipe 19 to clean the heat sink 9. The water mist sprayed on the heat sink 9 and the sprayed water curtain will be wrapped in the upper cleaning plate 10 and the lower cleaning plate 11, and drip downward or be swept into the flow groove of the lower cleaning plate 11 through the rubber pad layer, and then merged into the sealing baffle through the inclined flow groove, and then introduced into the liquid collection tank 2 by the water inlet pump, and filtered through the filter layer in the liquid collection tank 2;

[0062] During the movement of the upper cleaning plate 10, the driving assembly will engage with the rack 15, and through the cooperation of the gears and the crank slider mechanism, the auxiliary pipes 19 on both sides will be driven to swing. The swing of the auxiliary pipes 19 will increase the cleaning angle of the cleaning plate and form a swinging water curtain.

[0063] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
