Description

Technical Field

[0001] This utility model belongs to the technical field of blade cleaning devices, specifically a blade cleaning device for wind power generation equipment. Background Technology

[0002] Wind power generation equipment is a key device for converting wind energy into electrical energy. It mainly consists of wind turbine generator sets, control systems, foundation structures, and supporting power facilities. Its working principle is based on aerodynamics: wind blows the blades to rotate, which drives the generator rotor to cut magnetic field lines through a speed-increasing gearbox (or direct drive technology) to generate alternating current, which is then converted into electrical energy that meets the grid standards by a converter.

[0003] The blades of wind turbines are the core components of wind turbines, undertaking the crucial task of converting wind energy into mechanical energy. Their performance directly affects power generation efficiency and turbine lifespan. After manufacturing, wind turbine blades need to be cleaned to remove residual mold release agents, dust, resin debris, and other contaminants from the production process, ensuring surface cleanliness for subsequent quality inspection and ensuring coating adhesion. The current cleaning method generally involves operators rinsing the blades with a water gun. This method is not only inefficient but also prone to incomplete cleaning, and wastewater remains on the blade surface after a single rinse, resulting in poor cleaning performance. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a blade cleaning device for wind power generation equipment, which has the advantages of high efficiency and good effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blade cleaning device for wind power generation equipment, comprising a base frame, an mounting plate fixedly installed on the left side of the base frame, a first movable frame movably installed on the front of the base frame, a second movable frame movably installed on the back of the base frame, a connecting pipe movably sleeved inside the top of the second movable frame, a movable pipe fixedly connected to the bottom end of the connecting pipe, a high-pressure nozzle fixedly connected to the top of the movable pipe, a horizontal plate fixedly connected to the front end of the movable pipe, a vertical plate fixedly installed on the top of the horizontal plate, a round shaft fixedly installed on the top of the front of the vertical plate, a disc movably sleeved on the outer surface of the round shaft, the bottom of the disc fixedly connected to the top of the first movable frame, an insertion hole opened inside the front of the disc, a rotating plate fixedly sleeved on the front side of the outer surface of the round shaft, a bolt threaded inside the rotating plate, the rear end of the bolt penetrating the rotating plate and extending into the interior of the disc and movably sleeved with the inner wall of the disc.

[0006] As a preferred embodiment of this utility model, a motor is fixedly installed on the left side of the front of the bottom frame, and a threaded rod is fixedly connected to the other end of the motor output shaft. The outer surface of the threaded rod is movably sleeved with the inner wall of the bottom frame, and the outer surface of the threaded rod is threadedly sleeved with the inner wall of the first movable frame.

[0007] As a preferred embodiment of this utility model, a round rod is fixedly installed on the back of the bottom frame, and the outer surface of the round rod is movably sleeved with the inner wall of the second movable frame.

[0008] As a preferred embodiment of this utility model, a drain pipe is fixedly installed on the right side of the bottom frame, a fixing plate is fixedly installed on the back of the horizontal plate, and the other end of the fixing plate is fixedly connected to the inner surface of the movable pipe.

[0009] As a preferred embodiment of this utility model, fixing blocks are fixedly installed on both the front and rear sides of the top of the fixing plate, and a crossbar is fixedly connected between the fixing blocks. Moving blocks are movably sleeved on both the front and rear sides of the outer surface of the crossbar. The bottom of the moving blocks is movably connected to the top of the fixing plate, and a spring is fixedly connected to the outer surface of the moving blocks. The other end of the spring is fixedly connected to the outer surface of the fixing blocks.

[0010] As a preferred embodiment of this utility model, a hinge rod is hinged inside the top of the movable block, the top of the hinge rod is hinged to the bottom of the lifting plate, a cleaning sponge is fixedly connected to the top of the lifting plate, and a vertical rod is fixedly connected to the bottom of the lifting plate. The outer surface of the vertical rod is movably sleeved with the inner wall of the fixed plate.

[0011] As a preferred embodiment of the present invention, an installation block is fixedly installed on the back of the second movable frame, and a fixing tube is fixedly sleeved inside the installation block, with the outer surface of the fixing tube movably sleeved with the inner wall of the connecting tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a connecting pipe, a movable pipe, a high-pressure nozzle, and a vertical plate, allows the cleaning fluid to be delivered to the interior of the movable pipe through the connecting pipe and then sprayed onto the bottom of the blades through the high-pressure nozzle, thereby cleaning the blades. As the first movable frame moves, the blades can be thoroughly cleaned. Since there are two rows of high-pressure nozzles on the left and right, the outer surface of the blades can be cleaned more thoroughly. When the first movable frame moves to the far right, the rotating plate is rotated, causing the circular shaft to drive the vertical plate to rotate, which in turn causes the movable pipe to rotate 180 degrees, allowing the high-pressure nozzle to spray downwards, thereby cleaning the upper surface of the blades.

[0013] 2. This utility model, by setting up a crossbar, a moving block, a spring, and a cleaning sponge, allows the blade to contact the top of the cleaning sponge when it is installed on the right side of the mounting plate. This pushes the blade downward, causing the hinge rod to push the two moving blocks to move in opposite directions. This compresses the spring, which then generates a reverse elastic force under the elastic recovery action. This force pushes the lifting plate and the cleaning sponge upward through the hinge rod, causing the cleaning sponge to adhere tightly to the blade surface. This allows the blade to be wiped clean during the movement of the cleaning sponge. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6As shown, this utility model provides a blade cleaning device for wind power generation equipment, including a base frame 1, an mounting plate 2 fixedly installed on the left side of the base frame 1, a first movable frame 3 movably installed on the front of the base frame 1, a second movable frame 4 movably installed on the back of the base frame 1, a connecting pipe 5 movably sleeved inside the top of the second movable frame 4, a movable pipe 6 fixedly connected to the bottom end of the connecting pipe 5, a high-pressure nozzle 7 fixedly connected to the top of the movable pipe 6, a horizontal plate 8 fixedly connected to the front end of the movable pipe 6, a vertical plate 9 fixedly installed on the top of the horizontal plate 8, a round shaft 10 fixedly installed on the top of the front of the vertical plate 9, a disc 11 movably sleeved on the outer surface of the round shaft 10, the bottom of the disc 11 fixedly connected to the top of the first movable frame 3, an insertion hole 12 opened inside the front of the disc 11, a rotating plate 13 fixedly sleeved on the front side of the outer surface of the round shaft 10, a bolt 14 threaded inside the rotating plate 13, the rear end of the bolt 14 penetrating the rotating plate 13 and extending into the interior of the disc 11 and movably sleeved with the inner wall of the disc 11.

[0018] The operator can install the blades to be cleaned on the right side of the mounting plate 2 to fix the blades. When the cleaning fluid is delivered into the interior of the movable pipe 6 through the connecting pipe 5, it will clean the surface of the blades through the high-pressure nozzles 7. Since the high-pressure nozzles 7 are set in two rows, the two rows of high-pressure nozzles 7 can clean the blades more thoroughly. After the bottom of the blades is cleaned, the rotating plate 13 can be rotated, which will drive the vertical plate 9 to rotate through the round shaft 10, causing the movable pipe 6 to rotate upward by 180 degrees. This will allow the high-pressure nozzles 7 to spray downwards, thereby cleaning the upper surface of the blades.

[0019] Among them, a motor 15 is fixedly installed on the left side of the front of the bottom frame 1, and a threaded rod 16 is fixedly connected to the other end of the output shaft of the motor 15. The outer surface of the threaded rod 16 is movably sleeved with the inner wall of the bottom frame 1, and the outer surface of the threaded rod 16 is threadedly sleeved with the inner wall of the first movable frame 3.

[0020] The operator starts the motor 15, which causes the threaded rod 16 to drive the first moving frame 3 to move to the right, so that the cleaning fluid sprayed by the high-pressure nozzle 7 can thoroughly clean the blades.

[0021] A round rod 17 is fixedly installed on the back of the bottom frame 1, and the outer surface of the round rod 17 is movably connected to the inner wall of the second movable frame 4.

[0022] By setting the round rod 17, the round rod 17 can play a limiting role in the second moving frame 4.

[0023] A drain pipe 18 is fixedly installed on the right side of the bottom frame 1, and a fixing plate 19 is fixedly installed on the back of the horizontal plate 8. The other end of the fixing plate 19 is fixedly connected to the inner surface of the movable pipe 6.

[0024] By installing a drain pipe 18, the cleaning fluid inside the bottom frame 1 can be drained.

[0025] Among them, fixing blocks 20 are fixedly installed on the front and rear sides of the top of the fixing plate 19, and a crossbar 21 is fixedly connected between the fixing blocks 20. Moving blocks 22 are movably sleeved on the front and rear sides of the outer surface of the crossbar 21. The bottom of the moving block 22 is movably connected to the top of the fixing plate 19, and a spring 23 is fixedly connected to the outer surface of the moving block 22. The other end of the spring 23 is fixedly connected to the outer surface of the fixing block 20.

[0026] By setting spring 23, after being compressed, spring 23 can push moving block 22 to move under the limiting action of crossbar 21 under the elastic recovery action.

[0027] The movable block 22 has a hinge rod 24 hinged to its top, the top of the hinge rod 24 is hinged to the bottom of the lifting plate 25, the top of the lifting plate 25 is fixedly connected to a cleaning sponge 26, the bottom of the lifting plate 25 is fixedly connected to a vertical rod 27, and the outer surface of the vertical rod 27 is movably sleeved with the inner wall of the fixed plate 19.

[0028] By setting the vertical rod 27, the vertical rod 27 can limit the movement of the lifting plate 25, so that the lifting plate 25 and the cleaning sponge 26 can move more stably.

[0029] Among them, the back of the second movable frame 4 is fixedly installed with a mounting block 28, and a fixing tube 29 is fixedly sleeved inside the mounting block 28. The outer surface of the fixing tube 29 is movably sleeved with the inner wall of the connecting tube 5.

[0030] Due to the design of the mounting block 28, the mounting block 28 can fix the fixing pipe 29, so that the fixing pipe 29 can remain fixed when the connecting pipe 5 rotates.

[0031] Working principle and usage process of this utility model: When cleaning the blades, the blades are first installed on the right side of the mounting plate 2. Then, the external water pump is connected to the bottom end of the fixed pipe 29. After the blades are installed, they will contact the top of the cleaning sponge 26. At this time, the spring 23 will be compressed, so that the spring 23 can push the moving block 22 under the elastic recovery action. This pushes the lifting plate 25 and the cleaning sponge 26 upward through the hinge rod 24, so that the cleaning sponge 26 can stick to the lower surface of the blade. Then, the operator starts the motor 15, so that the threaded rod 16 drives the first moving frame 3 to move to the right, so that the cleaning sponge 26 moves along the bottom of the blade, thereby cleaning the blade.

[0032] Because the high-pressure nozzles 7 are designed with two rows on the left and right, the water jets from the high-pressure nozzles 7 in the forward direction, in conjunction with the cleaning sponge 26, can effectively clean the blades. The high-pressure nozzles 7 in the rear row can rinse the sewage on the blades, making the blades cleaner. When the first moving frame 3 moves to the rightmost side of the travel, the bolt 14 is rotated to disengage from the inside of the disc 11. Then, the rotating plate 13 is rotated, causing the shaft 10 to drive the vertical plate 9 to rotate, thereby causing the movable tube 6 to rotate 180 degrees. This allows the high-pressure nozzles 7 to spray downwards to clean the upper surface of the blades. Then, the bolt 14 is rotated again to insert it into the insertion hole 12, thereby fixing the position of the movable tube 6. At this time, the motor 15 is started, causing the threaded rod 16 to reverse, thereby driving the first moving frame 3 to move to the left to clean the top of the blades.
