Description
Technical Field
[0001] This utility model relates to the field of wind turbine blade cleaning technology, and in particular to a large-area high-level cleaning device for wind turbine blades. 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 have a direct impact on the overall power generation efficiency and equipment lifespan. After the blades are polished, they must be cleaned to ensure that the surface is clean. However, the existing cleaning devices are inefficient and have poor cleaning effects. Utility Model Content
[0004] The main purpose of this utility model is to solve the above-mentioned technical problems to a certain extent, and to propose a large-area high-level cleaning device for wind turbine blades, which can improve the cleaning efficiency of the blades by sweeping and suctioning at the same time, and ensure the cleaning effect of the blades.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a large-area high-level cleaning device for wind turbine blades, comprising a housing, brushes, and a quick-release operating rod. The lower surface of the housing is recessed with a groove, and two brushes are disposed on the left and right sides of the housing, so that the space between the two brushes and the groove form a dust-collecting chamber. The upper surface of the housing is provided with a first through-slot communicating with the dust-collecting chamber. A first fixed seat is provided on the upper surface of the housing, sealing the first through-slot, and a second through-slot communicating with the first through-slot is provided on the first fixed seat. A second fixed seat is provided on one side of the upper surface of the housing, and the quick-release operating rod is hinged to the second fixed seat, and its movement drives the cleaning direction of the housing. The quick-release operating rod is connected to an external wind turbine and dust collection box. The first fixed seat and the quick-release operating rod are connected through a connecting pipe.
[0006] In some embodiments, the housing includes a front housing and a rear housing, which are assembled and connected by a plurality of connectors. The lower end faces of the front housing and the rear housing are recessed with grooves. The first through groove is provided in the front housing, and the second fixing seat is provided in the rear housing. The front end of the front housing and the rear end of the rear housing are respectively provided with protrusions extending downward, and the two brushes are respectively assembled on both sides of the protrusions.
[0007] In some embodiments, the front end of the front housing and the rear end of the rear housing are provided with baffles covering the protrusion and the end of the brush.
[0008] In some embodiments, the quick-release operating lever includes a mounting sleeve and a tube body. The outer surface of the mounting sleeve is symmetrically provided with mounting shafts. The mounting shafts are rotatably assembled in the slots provided by the second fixing seat. The two ends of the mounting sleeve are respectively sealed and assembled with the tube body and the connecting pipe.
[0009] In some embodiments, the end of the mounting sleeve that mates with the connecting pipe is conical.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] This invention involves attaching a brush to the surface of the blades. By pushing a quick-release operating lever, the housing moves, allowing the brush to clean the surface of the blades. The dust cleaned by the brush enters the suction chamber as the housing moves. A fan creates negative pressure in the suction chamber, causing the dust to be discharged into the dust collection box via the first fixed seat, connecting pipe, and quick-release operating lever. This method of use improves the cleaning efficiency of the blades by simultaneously sweeping and suctioning, while ensuring the cleanliness of the blades.
[0012] Furthermore, depending on the height of the blade, the length of the tube 302 can be quickly increased or decreased, and the mounting shaft is rotatably mounted in the second fixed seat via a hinge, which can meet the cleaning requirements of the curved surfaces of the blades with different curvatures.

Two brushes 2 are respectively assembled on both sides of the protrusions 4, and the brushes 2 are flush with the left and right sides of the front housing 101 and the rear housing 102, so that the space between the two brushes 2 and the grooves form a dust collection chamber 5. The front end of the front housing 101 and the rear end of the rear housing 102 are provided with baffles 6 covering the protrusions 4 and the ends of the brushes 2. The upper surface of the front housing 101 is provided with a first through groove 7 communicating with the dust collection chamber 5. The upper surface of the housing 102 is sealed and covered by a first through groove 7 and has a first fixed seat 8. The first fixed seat 8 has a second through groove 9 that communicates with the first through groove 7. A connecting pipe 10 is sealed and assembled on the first fixed seat 8. The connecting pipe 10 is a flexible hose. A second fixed seat 11 is provided on one side of the upper surface of the rear housing 102. The quick-release operating lever 3 includes a mounting sleeve 301 and a tube body 302. The outer surface of the mounting sleeve 301 is symmetrically provided with mounting shafts 303. The mounting shafts 303 are rotatably assembled in the slots provided in the second fixed seat 11. The two ends of the mounting sleeve 301 are respectively sealed and assembled with the tube body 302 and the connecting pipe 10.
