Description

Technical Field

[0001] This invention relates to the technical field of wind turbine blade cleaning, and more particularly to a wind power generation blade cleaning device. Background Technology

[0002] Wind power generation, as a technology that converts the kinetic energy of wind into electrical energy, utilizes wind energy—a clean, pollution-free, and inexhaustible renewable energy source—to effectively mitigate the consumption of fossil fuels and reduce greenhouse gas emissions. It is particularly important in water-scarce, fuel-scarce, and inaccessible coastal islands, grassland pastoral areas, mountainous regions, and plateaus, due to its advantages of not being limited by geography and resources. It not only meets the energy needs of these regions but also promotes local economic development and environmental protection.

[0003] As a key component of wind turbines, the production and maintenance of wind turbine blades directly impact overall power generation efficiency and equipment lifespan. Wind turbine blades are typically manufactured using composite materials, offering high strength and durability. However, after mass production, blades stored in factories or warehouses for extended periods easily accumulate dust and dirt. If this dust remains on the blade surface, it will affect the blade's aerodynamic performance, consequently impacting the efficiency and stability of the wind turbine. Therefore, blades must undergo thorough cleaning before being packaged and shipped to ensure surface cleanliness.

[0004] The current common cleaning method involves placing the blades directly on the ground and rinsing them with a high-pressure water gun. However, this method has significant drawbacks: ground dust is easily splashed up by the water flow, causing secondary pollution. Thorough cleaning of the blades usually requires repeated washing, which not only consumes a large amount of water and manpower but also increases cleaning costs. Furthermore, the use of high-pressure water guns can cause wear and tear on the blade surface, affecting its lifespan. Summary of the Invention

[0034] Example 1

[0035] Reference Figure 1 The first embodiment of the present invention provides a wind turbine blade cleaning device, which includes a support assembly 100, including a base 101 and a mounting bracket 102 symmetrically connected to its top.

[0036] The base 101 is a fixed support base for the device, which can ensure the safe operation of the device. The mounting frame 102 is fixedly installed above the base 101. In this embodiment, two sets are preferably provided. The mounting frame 102 has a "door" shaped structure, and the blades can be placed in the "mouth" shaped cleaning space formed by the base 101 and the mounting frame 102.

[0037] The cleaning component 200 includes a cleaning component 201, a sweeping component 202, and a blowing component 203. The cleaning component 201 is disposed on the top of the base 101, and the sweeping component 202 and the blowing component 203 are both disposed on the mounting bracket 102, with the sweeping component 202 symmetrically disposed on both sides of the blowing component 203.

[0038] The cleaning component 201 is installed inside the base 101 and can spray water or cleaning liquid upwards to rinse the bottom of the blades. Each set of mounting brackets 102 is equipped with a set of cleaning components 202, which can slide up and down on the mounting brackets 102 to accommodate cleaning blades of different sizes.

[0039] Furthermore, the blower 203 is slidably installed between the two sets of mounting brackets 102, and its height is always higher than that of the cleaning component 202. The blower 203 can blow off the dust or water stains on the blades, thus speeding up the cleaning process.

[0040] The drive assembly 300 includes a first drive member 301 and a second drive member 302. The first drive member 301 is disposed on the top of the mounting bracket 102 and its output shaft is connected to the cleaning member 202. The second drive member 302 is mounted on the top of the cleaning member 202.

[0041] The first driving component 301 can drive the cleaning component 202 to move up and down, and the second driving component 302 drives the cleaning component 202 to rotate, thus cleaning the surface of the blade. In this device, both the first driving component 301 and the second driving component 302 are preferably driven motors.

[0042] Example 2

[0043] Reference Figure 1 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the base 101 includes symmetrically arranged load-bearing seats 101a and load-bearing platforms 101b connected to its inner wall. A base plate 101c is also fixedly connected between the load-bearing platforms 101b.

[0044] The bottom of the support base 101a is symmetrically connected with anti-slip feet 101a-1 at the four corners. The top of the support platform 101b on the side away from the support base 101a has a first inclined surface X1. A water leakage space A is formed between the top of the base plate 101c and the support platform 101b. The cleaning component 201 is set in the water leakage space A.

[0045] Preferably, four sets of anti-slip feet 101a-1 are provided, which are respectively installed at the four corners of the bottom of the base 101 to ensure that the base 101 is level and avoids tilting.

[0046] The mounting bracket 102 includes symmetrically arranged vertical beams 102a and horizontal beams 102b connected at their tops. The vertical beams 102a have a first sliding hole 102a-1, and the adjacent side walls of the symmetrical vertical beams 102a also have a second sliding hole 102a-2. A horizontal frame 102c is also fixedly connected between the tops of the vertical beams 102a, and a first spring T1 is fixed at the bottom of the horizontal frame 102c.

[0047] The first sliding hole 102a-1 extends horizontally through the vertical beam 102a, while the second sliding hole 102a-2 is opened on the relatively adjacent side of the vertical beam 102a, and the first spring T1 is vertically installed between the two mounting brackets 102.

[0048] The bottom end of the vertical beam 102a is fixedly connected to the top of the support seat 101a. A lead screw 102a-1a is also rotatably inserted into the first sliding hole 102a-1 along its length direction. The lead screw 102a-1a is fixedly connected to the output shaft of the first drive component 301.

[0049] The cleaning component 202 includes a mounting plate 202a and a telescopic cleaning component 202b rotatably connected at its bottom at equal intervals. The second driving component 302 is fixedly connected to the top of the mounting plate 202a.

[0050] The telescopic sweeping component 202b includes a rotating sleeve 202b-1, a telescopic rod 202b-2, and a sweeping cloth 202b-3. The rotating sleeve 202b-1 is rotatably inserted into the mounting plate 202a. One set of rotating sleeves 202b-1 is fixedly connected to the output shaft of the second drive component 302. The top of the remaining rotating sleeves 202b-1 is fixedly connected with an anti-detachment cap 202b-1a. The anti-detachment cap 202b-1a can ensure that the rotating sleeves 202b-1 on both sides can rotate on the mounting plate 202a without falling off.

[0051] The telescopic rod 202b-2 can be slidably inserted into the rotating sleeve 202b-1, and the cleaning cotton 202b-3 is fixed at the bottom of the telescopic rod 202b-2.

[0052] Among them, the cleaning cotton 202b-3 is always in contact with and adheres to the upper surface of the blade below during the working process.

[0053] A frustum 202b-1b is fixed to the outer wall of the bottom end of the rotating sleeve 202b-1. A connector strip 202b-1c is symmetrically connected to its inner wall. A strip groove 202b-2a is symmetrically opened on the outer wall of the telescopic rod 202b-2. The connector strip 202b-1c is slidably inserted into the strip groove 202b-2a. A second spring T2 is also sleeved on the telescopic rod 202b-2 between the frustum 202b-1b and the cleaning cotton 202b-3.

[0054] A first gear C1 is fixedly sleeved on the outside of the rotating sleeve 202b-1, and a second gear C2 is rotatably connected on the mounting plate 202a between the rotating sleeves 202b-1. The first gear C1 and the second gear C2 are meshed together.

[0055] The remaining structure is the same as that in Example 1.

[0056] During use, the second drive unit 302 is activated, and its output shaft drives the rotating sleeve 202b-1 connected to it to rotate. Under the restriction of the strip groove 202b-2a and the plug bar 202b-1c, the telescopic rod 202b-2 will rotate together with the rotating sleeve 202b-1.

[0057] Furthermore, the cleaning cotton 202b-3 rotates accordingly, cleaning the upper surface of the blade. The cleaning cotton 202b-3 is preferably made of sponge material, which will not scratch the blade body.

[0058] Furthermore, the central rotating sleeve 202b-1 rotates under the drive of the second driving member 302, and the first gear C1 in the middle drives the next set of rotating sleeves 202b-1 to rotate through the adjacent meshing second gear C2. Similarly, the remaining rotating sleeves 202b-1 will also rotate.

[0059] During this process, the adjacent cleaning sponges 202b-3 rotate in opposite directions, which can improve the cleaning effect; and because the blade structure is undulating and irregularly flat and long, it is necessary to ensure that the upper surface of the blade is always in contact with the cleaning sponge 202b-3 during the cleaning process.

[0060] At this time, since each set of telescopic rods 202b-2 is independently inserted into the rotating sleeve 202b-1, they can extend to different lengths respectively, and under the action of the second spring T2, the cleaning cotton 202b-3 is always pressed against the blade surface at the corresponding position.

[0061] Example 3

[0062] Reference Figure 1This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the blower 203 includes a drive pump 203a, a hollow cross frame 203b, and a jet head 203c. The drive pump 203a is fixedly installed on the top of the hollow cross frame 203b, and the jet heads 203c are arranged and installed at the bottom of the hollow cross frame 203b. The output end of the drive pump 203a is connected to the jet head 203c. Both the drive pump 203a and the jet head 203c are prior art.

[0063] During use, the drive pump 203a can inject a large amount of air into the jet head 203c, and then spray it from the output end of the jet head 203c onto the upper surface of the blade, blowing off the dust or water stains on the blade.

[0064] The hollow cross frame 203b has symmetrically provided stabilizing plates 203b-1 and sliding rods 203b-2 at both ends and on the side walls. The sliding rods 203b-2 are slidably inserted into the second sliding hole 102a-2, and the first spring T1 is connected to the top of the hollow cross frame 203b.

[0065] During use, the hollow crossbeam 203b is positioned below the vertical beam 102a. At this time, the first spring T1 is in a naturally extended state, and the stabilizing plate 203b-1 clamps the vertical beam 102a from both sides, ensuring that the hollow crossbeam 203b slides smoothly vertically.

[0066] The two ends of the mounting plate 202a are slidably inserted into the first sliding hole 102a-1. The screw 102a-1a is rotatably inserted into the mounting plate 202a and threadedly connected to the mounting plate 202a. The mounting plate 202a is also fixedly connected to the side of the mounting plate 202a near the second sliding hole 102a-2. The abutment insertion platform 202a-2 extends out of the second sliding hole 102a-2 and abuts against the bottom of the sliding insertion rod 203b-2.

[0067] In the initial state, the two sets of mounting horizontal plates 202a are at the same horizontal height and are both located below the device. At this time, the abutment platform 202a-2 is located at the bottom of the sliding rod 203b-2, that is, the hollow horizontal frame 203b is placed entirely above the abutment platform 202a-2.

[0068] During use, if one of the mounting plates 202a moves upward, the blower 203 can be lifted upward by abutting the insertion platform 202a-2, so that the jet head 203c inside the blower 203 will always face the downward blades.

[0069] Furthermore, regardless of which of the two sets of cleaning components 202 moves upward, it can drive the blower component 203 to rise, ensuring that the blower component 203 works normally.

[0070] The inner wall of the opposite side of the support platform 101b is connected to at least one set of conveyor wheels 101b-1; the conveyor wheels 101b-1 can protect the blade side edge from impacting the support seat 101a and causing blade scratches.

[0071] A protective leak plate 101d is also installed between the load-bearing seats 101a, and the protective leak plate 101d covers the top of the leak space A.

[0072] The protective plate 101d has at least one set of lower leakage strip holes 101d-1 arranged on it. The lower leakage strip holes 101d-1 have symmetrically arranged inner holes 101d-1a on the longer side walls. The protective plate 101d-1b is symmetrically slidably inserted into the inner hole 101d-1a. A third spring T3 is connected between the protective plate 101d-1b and the inner hole 101d-1a. A second inclined surface X2 is opened at the bottom of the end of the protective plate 101d-1b away from the third spring T3.

[0073] Water or dust can fall from the lower drain hole 101d-1 onto the bottom plate 101c instead of accumulating on the upper surface of the protective drain plate 101d.

[0074] A connecting plate 101d-2 is symmetrically connected to the bottom of the protective leak plate 101d. A connecting block 101d-2a is connected between the connecting plate 101d-2 and the protective leak plate 101d. Sliding sleeves 102d-2b are fixedly connected to both ends of the connecting plate 101d-2. Triangular blocks 101d-3 are also fixedly connected to both ends of the bottom of the protective leak plate 101d. The third inclined surface X3 on the triangular block 101d-3 abuts against the first inclined surface X1.

[0075] The top edge of the base plate 101c is symmetrically connected with a sliding column 101c-1, and a sliding sleeve 102d-2b is slidably sleeved on the top of the sliding column 101c-1. A fourth spring T4 is also sleeved on the outside of the sliding column 101c-1.

[0076] If no blades are placed above the protective leak plate 101d, the protective leak plate 101d will be pushed upward under the action of the fourth spring T4, and the third inclined surface X3 will separate from the first inclined surface X1.

[0077] Furthermore, under the action of the third spring T3, the protective plate 101d-1b extends out from the embedded hole 101d-1a, and the end of the protective plate 101d-1b with the second inclined surface X2 abuts against each other. At this time, the second inclined surface X2 forms an inverted "V" shaped groove.

[0078] The cleaning component 201 includes a vertical plate 201a, a horizontal assembly plate 201b, a cleaning nozzle 201c, and a water pump 201d. The horizontal assembly plate 201b is fixed to the top of the base plate 101c. The vertical plate 201a is symmetrically connected to both ends of the horizontal assembly plate 201b. The cleaning nozzle 201c is installed on the horizontal assembly plate 201b. The water pump 201d is connected to each set of cleaning nozzles 201c through a pipe 201d-1.

[0079] During use, the water pump 201d is connected to the external water supply pipe, and clean water is delivered to the cleaning nozzle 201c through the pipe 201d-1.

[0080] The upright plate 201a can be inserted into the lower drain hole 101d-1. The top of the plate is symmetrically provided with a fourth inclined surface X4 and a snap-fit ​​groove 201a-1 on both sides near the embedded hole 101d-1a. The snap-fit ​​groove 201a-1 includes a vertical groove wall 201a-1a and a first inclined wall X5 and a second inclined wall X6 on both sides. The protective plate 101d-1b can be snapped into the snap-fit ​​groove 201a-1. The fourth inclined surface X4 and the second inclined surface X2 are obliquely abutted.

[0081] During use, after the blade is placed above the protective sprue plate 101d, the protective sprue plate 101d is subjected to pressure and moves downward. At this time, the fourth inclined surface X4 contacts and presses against the second inclined surface X2, causing the protective plate 101d-1b to open to both sides. The cleaning nozzle 201c extends from the lower sprue hole 101d-1 and sprays water onto the blade above to clean it.

[0082] Furthermore, when the protective leak plate 101d descends to the position where the triangular block 101d-3 contacts the first inclined surface X1, the protective plate 101d-1b is just inserted into the snap-fit ​​groove 201a-1. At this time, the second inclined surface X2 is in contact with the second inclined wall X6, and the protective leak plate 101d is always in a state of opening to both sides under the action of the vertical plate 201a.

[0083] After the blades are removed, the fourth spring T4 resets and pushes the protective leak plate 101d upward. At this time, the upper surface of the protective plate 101d-1b slides obliquely relative to the first inclined wall X5, and the vertical plate 201a retracts to below the protective leak plate 101d. The protective plate 101d-1b re-seals the lower leak strip hole 101d-1, protecting the cleaning nozzle 201c below.

[0084] In summary, during use, the fan blades move to the top of the protective leak plate 101d with the help of the warehouse transport device, and then the upper part of the protective leak plate 101d is squeezed from below. At this time, the protective plate 101d-1b opens to both sides and the cleaning nozzle 201c extends out.

[0085] It should be noted that the leading edge of the blade can be cleaned first. After the upper and lower surfaces are cleaned, the blade can be lifted up again with the help of a transport device and then moved forward to avoid the protective plate 101d from scratching the blade surface.

[0086] Furthermore, during the process of the blade being lifted and moved forward, the cleaning component 202 and the blowing component 203 located above the blade will be raised to their highest positions to prevent them from contacting and squeezing the upper surface of the blade, thus preventing damage to the blade.

[0087] Furthermore, since the blades are relatively large, the cleaning process is quite slow. Therefore, the cleaned parts can be covered with a dustproof cloth to prevent dust from falling back onto the blades during the subsequent cleaning process.

[0088] Furthermore, when the blade is placed above the protective baffle 101d, the cleaning component 202 and the blowing component 203 located above the blade move downward under the drive of the first driving component 301, so that the lower end of the telescopic cleaning component 202b contacts the surface of the blade, reaching a position where dust can be cleaned.

[0089] Furthermore, the blower 203 can be pushed and controlled by the cleaning components 202 on both sides, but it can also ensure that it is always in a high position above the blades, so that the jet head 203c can blow away the water and dust on the blades over the largest area.

[0090] The remaining structure is the same as that in Example 2.

[0091] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
