Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wind turbine blade repair technology, and specifically relates to a wind turbine blade repair and grinding device with a collection function. Background Technology
[0002] Wind turbine blades are constantly exposed to a complex and ever-changing natural environment, making them highly susceptible to surface damage (such as wear, cracks, and coating peeling) caused by factors like wind and sand erosion, rainwater erosion, and ultraviolet radiation. With increasing usage time, this damage significantly increases blade surface roughness, thereby affecting its aerodynamic performance and reducing wind energy conversion efficiency and power generation. Therefore, regular blade polishing and maintenance are crucial: not only can they effectively repair damage and extend blade life, but they can also improve power generation efficiency by restoring blade surface smoothness, ensuring the stable operation of the entire wind power generation system.
[0003] When using grinding devices to repair wind turbine blades, the centrifugal force generated by the grinding discs stirs up a large amount of harmful dust containing glass fibers, resin, and other materials, creating dust storms. Long-term inhalation of this dust by maintenance personnel can easily lead to respiratory illnesses and other health problems. Furthermore, this dust readily adheres to the ground blade surface, weakening the adhesion of subsequent repair materials, reducing repair quality, and potentially causing dynamic imbalances during high-speed blade operation, leading to vibrations and safety hazards. Utility Model Content
[0004] In view of the problem that the dust generated when grinding wind turbine blades can easily cause respiratory diseases to maintenance personnel, this utility model proposes a wind turbine blade maintenance and grinding equipment with a collection function to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a wind turbine blade repair and grinding device with a collection function, including a grinding body, a grinding component and an elastic shielding component are provided at one end of the grinding body, the elastic shielding component is provided on the outside of the grinding component, an extraction component is provided on the outside of the grinding body, the extraction component is connected to the elastic shielding component, and a collection component is provided inside the extraction component.
[0007] The grinding component is used to grind wind turbine blades, the elastic shielding component is used to shield the dust generated during grinding, and the extraction component is used to extract the dust inside the elastic shielding component so that the collection component can collect the dust.
[0008] Furthermore, the polishing assembly includes a mounting base, which is fixedly connected to the bottom of the polishing body. A rotating shaft is rotatably connected to the bottom of the mounting base. A connecting plate is fixedly installed at the bottom end of the rotating shaft. A polishing disc is fixedly connected to the bottom of the connecting plate. A scraper is fixedly connected to the outer side of the connecting plate.
[0009] Furthermore, the elastic shielding assembly includes a T-shaped cylinder, which is connected to the bottom of the mounting base above the top. The T-shaped cylinder is located on the outside of the rotating shaft. A shielding cover is movably connected to the outer surface of the T-shaped cylinder. A push spring is fixedly connected between the shielding cover and the mounting base. The scraper is in contact with the inner wall of the shielding cover.
[0010] Furthermore, the extraction component includes a storage box, a fan is fixedly installed on the back of the storage box, an extraction tube is fixedly connected to one side of the storage box, and one end of the extraction tube is fixedly connected to a shield.
[0011] Furthermore, the collection component includes a limiting frame, which is fixedly connected to the inner wall of the storage box. A collection box is movably connected to one side of the limiting frame. The top of the collection box extends to the outside of the storage box and is fixedly connected to a handle. A through groove is provided on one side of the collection box corresponding to the extraction tube. A mesh is provided on the back of the collection box corresponding to the limiting frame.
[0012] Furthermore, the storage box has an internal mounting cavity, in which a storage battery is fixedly installed. The grinding body and the exhaust fan are both electrically connected to the storage battery.
[0013] Furthermore, a carrying strap is fixedly connected to the front of the storage box.
[0014] This utility model has the following beneficial effects:
[0015] 1. When the present invention uses the grinding component to perform fixed grinding on wind turbine blades, the blocking end of the elastic blocking component can block the grinding position under the push of the elastic end, so that the dust generated during the operation of the grinding component will not drift out from the inside of the elastic blocking component. At the same time, the extraction component can extract the dust inside the blocking end into the collection component. The above settings prevent dust from being generated when grinding wind turbine blades, thus ensuring the health of maintenance personnel. At the same time, it greatly reduces the dust residue on the blade surface, thereby significantly reducing the difficulty of subsequent cleaning work.
[0016] 2. When the wind turbine blades are polished by the polishing disc, the dust generated during polishing is thrown to the inner wall of the shield under the centrifugal force of the polishing disc. Since the connecting disc synchronously drives the polishing disc and the scraper to rotate, and the scraper keeps in contact with the inner wall of the shield, the rotating scraper can continuously push the dust on the inner wall to the extraction pipe port. This directional pushing significantly improves the dust extraction efficiency of the extraction pipe.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0029] Please see Figures 1-6 As shown, this utility model is a wind turbine blade repair and grinding device with a collection function, including a grinding body 1. A grinding component 2 and an elastic shielding component 3 are provided at one end of the grinding body 1. The elastic shielding component 3 is provided on the outside of the grinding component 2. An extraction component 4 is provided on the outside of the grinding body 1. The extraction component 4 is connected to the elastic shielding component 3. A collection component 5 is provided inside the extraction component 4.
[0030] The grinding component 2 is used to grind the wind turbine blades, the elastic shielding component 3 is used to shield the dust generated during grinding, and the extraction component 4 is used to extract the dust inside the elastic shielding component 3 so that the collection component 5 can collect the dust.
[0031] By placing the grinding component 2 on the wind turbine blade where grinding is required, the grinding component 2 grinds the wind turbine blade. At the same time, the elastic shielding component 3 can block the dust, the extraction component 4 extracts the dust blocked inside the elastic shielding component 3, and the collection component 5 collects the extracted dust.
[0032] When the wind turbine blades are being ground by the grinding assembly 2, the shielding end of the elastic shielding assembly 3 can shield the grinding position under the push of the elastic end, so that the dust generated by the grinding assembly 2 during operation will not drift out from the inside of the elastic shielding assembly 3. At the same time, the extraction assembly 4 can extract the dust inside the shielding end into the collection assembly 5. The above settings ensure that no dust is generated when grinding the wind turbine blades, thus ensuring the health of maintenance personnel. At the same time, it also greatly reduces the dust residue on the blade surface, thereby significantly reducing the difficulty of subsequent cleaning work.
[0033] In one embodiment, the grinding assembly 2 includes a mounting base 201, which is fixedly connected to the bottom of the grinding body 1. A rotating shaft 202 is rotatably connected to the bottom of the mounting base 201. A connecting plate 203 is fixedly installed at the bottom end of the rotating shaft 202. A grinding disc 204 is fixedly connected to the bottom of the connecting plate 203. A scraper 205 is fixedly connected to the outer side of the connecting plate 203.
[0034] The grinding body 1 is equipped with a motor, the output end of which is connected to the rotating shaft 202. When grinding the wind turbine blade, the grinding body 1 places the grinding disc 204 in a suitable position, and then drives the rotating shaft 202 through the motor. This causes the rotating shaft 202 to drive the grinding disc 204 to rotate through the connecting plate 203. The rotating grinding disc 204 then grinds the surface of the blade. During this process, the dust that is ground off can be thrown to the inner wall of the shielded end by the centrifugal force of the grinding disc 204. The scraper 205, driven by the connecting plate 203, can push the dust at the shielded end, so that the dust can continuously move to the extraction end of the extraction component 4, thereby enabling the extraction component 4 to extract the dust more effectively.
[0035] In one embodiment, the elastic shielding component 3 includes a T-shaped cylinder 301, which is connected to the bottom of the mounting base 201. The T-shaped cylinder 301 is disposed on the outside of the rotating shaft 202. A shielding cover 302 is movably connected to the outer surface of the T-shaped cylinder 301. A push spring 303 is fixedly connected between the shielding cover 302 and the mounting base 201. The scraper 205 is in contact with the inner wall of the shielding cover 302.
[0036] The push spring 303 pushes the shield 302 downward, causing the shield 302 to contact the edge of the T-shaped cylinder 301, while its bottom is located below the grinding disc 204. When grinding the blade, the shield 302 is placed in a suitable position by the grinding body 1, and then the grinding body 1 is pressed downward. At this time, the shield 302 can push the push spring 303 upward, and the shield 302 slides continuously on the T-shaped cylinder 301. When the grinding disc 204 contacts the blade, the pressing of the grinding body 1 is stopped, and the grinding operation begins. The above arrangement allows the shield 302 to contact the blade surface relatively tightly, and the shield 302 does not cause obstruction after the grinding disc 204 contacts the blade.
[0037] In one embodiment, the extraction component 4 includes a storage box 401, a fan 402 is fixedly installed on the back of the storage box 401, an extraction tube 403 is fixedly connected to one side of the storage box 401, and one end of the extraction tube 403 is fixedly connected to a shield 302.
[0038] The exhaust fan 402 can draw air from the inner wall of the storage box 401, thereby creating a negative pressure inside the storage box 401. At this time, the extraction pipe 403 generates suction under the action of negative pressure, so that when the dust is pushed to one end of the extraction pipe 403 by the scraper 205, the extraction pipe 403 can extract the dust, and the extracted dust falls directly into the inside of the storage box 401 under the guidance of the extraction pipe 403.
[0039] In one embodiment, the collection component 5 includes a limiting frame 501, which is fixedly connected to the inner wall of the storage box 401. A collection box 502 is movably connected to one side of the limiting frame 501. The top of the collection box 502 extends to the outside of the storage box 401 and is fixedly connected to a handle 503. A through groove 504 is provided on one side of the collection box 502 corresponding to the extraction tube 403. A mesh 505 is provided on the back of the collection box 502 corresponding to the limiting frame 501.
[0040] The limiting frame 501 can limit the collection box 502 inside the storage box 401. At the same time, the exhaust fan 402 can extract air from inside the collection box 502 through the mesh 505. When dust is inside the storage box 401 under the guidance of the extraction pipe 403, it can fall directly into the collection box 502 through the channel 504. At this time, the exhaust fan 402 will not extract the dust from the collection box 502 due to the obstruction of the mesh 505, so that the collection box 502 can collect the dust better. When cleaning the collected dust, the collection box 502 can be lifted upward by the handle 503, so that the collection box 502 can be moved out from inside the storage box 401, and then the dust inside the collection box 502 can be poured out through the channel 504.
[0041] In one embodiment, the storage box 401 has an internal mounting cavity 6, and a storage battery 7 is fixedly installed inside the mounting cavity 6. The grinding body 1 and the exhaust fan 402 are both electrically connected to the storage battery 7.
[0042] The battery 7 can power the exhaust fan 402 of the grinding body 1. Since the battery 7 is located inside the storage box 401, the battery 7 can be set to a larger size. At the same time, the battery 7 can provide power to the grinding body 1 and the exhaust fan 402 for a longer period of time. This setting means that maintenance personnel do not need to worry about insufficient power when performing high-altitude operations.
[0043] In one embodiment, the storage box 401 described above has a shoulder strap 8 fixedly connected to its front.
[0044] The operator can carry the storage box 401 on their back using the shoulder strap 8. This design allows maintenance personnel to free their hands and focus on performing maintenance tasks when working at heights. At the same time, the storage box 401 can move with the maintenance personnel, so that the extraction and collection of dust can be carried out normally.
[0045] Through the above technical solution: 1. When the wind turbine blade is polished by the polishing component 2, the shielding end of the elastic shielding component 3 can shield the polishing position under the push of the elastic end, so that the dust generated when the polishing component 2 is working will not drift out from the inside of the elastic shielding component 3. At the same time, the extraction component 4 can extract the dust inside the shielding end into the collection component 5. The above settings ensure that no dust is generated when polishing the wind turbine blade, thus ensuring the health of maintenance personnel. At the same time, it greatly reduces the dust residue on the blade surface, thereby significantly reducing the difficulty of subsequent cleaning work.
[0046] 2. When the wind turbine blades are polished by the polishing disc 204, the dust generated during polishing is thrown to the inner wall of the shield 302 under the centrifugal force of the polishing disc 204. Since the connecting disc 203 synchronously drives the polishing disc 204 and the scraper 205 to rotate, and the scraper 205 keeps in contact with the inner wall of the shield 302, the rotating scraper 205 can continuously push the dust on the inner wall to the port of the extraction pipe 403. This directional pushing significantly improves the dust extraction efficiency of the extraction pipe 403.
