Description

Technical Field

[0001] The utility model relates to the field of cleaning, in particular to a cleaning device. Background Art

[0002] As a renewable and clean energy source, wind power generation is becoming increasingly important for generator maintenance, tower cleaning, and blade inspection. The tower is the support frame of the wind turbine, and there are problems such as dust pollution, oil pollution, corrosion and rust, and oil pollution is particularly serious. As the working time of the wind turbine increases, the oil pollution will become more serious, which not only affects the beauty of the tower, but also causes serious damage to the paint surface of the tower, making the tower surface more prone to corrosion and rust. Large-area oil pollution will make the entire tower surface without paint protection, which will reduce the anti-corrosion performance of the tower, shorten the service life, stress deformation, reduce the structural strength, and cause the risk of tower collapse. Therefore, tower cleaning is very important. Traditional cleaning mechanisms and cleaning robots usually use an integrated mechanism that cannot be quickly disassembled and transported to the site. It is not convenient to replace different devices in time when in use. At the same time, the traditional cleaning method cannot clean the root position of the wind turbine tower cabin, and cannot adapt to the changes in the upper and lower diameters of the tower well, resulting in inconvenient transportation, small cleaning range, incomplete cleaning position, and low cleaning efficiency for the cleaning structure.

[0026] As a renewable and clean energy source, wind power generation is becoming increasingly important for generator set maintenance, tower cleaning, and blade inspection. At present, the main methods of tower cleaning are manual operation and sling cleaning robots. Generally, most of them are completed by manual high-altitude cleaning operations. The operators are attached to the tower by hanging on the rope and manually clean the tower from top to bottom. There are problems such as low cleaning efficiency, long cleaning cycle, high risk factor, low safety, high labor intensity, high labor cost, and high cleaning cost. Some sling cleaning robots are used. The roller brush 31 is set in the middle position of the working device, and it is impossible to clean the root position of the wind turbine tower 50 cabin. At the same time, different working devices cannot be replaced to clean the wall of the wind turbine tower 50 with different curvature radii, making transportation inconvenient, the cleaning range is small, and the cleaning position is not thorough. The tower cleaning mechanism 20 and the cleaning robot, for many reasons, have product structures that cannot be modularly disassembled and transported, cannot replace different working devices, cannot clean the root position of the wind turbine tower 50 cabin, and cannot adapt to changes in the upper and lower diameters of the tower. Therefore, it is an urgent problem to design a cleaning mechanism 20 and a cleaning robot that can be modularly disassembled and transported, can replace different working devices, can clean the root of the wind turbine tower 50 nacelle, can automatically adapt to the changes in the upper and lower diameters of the tower, and are easy to transport, have a large cleaning range, clean the position thoroughly, have a good cleaning effect, and have a high cleaning efficiency.

[0027] See also Figure 1 and Figure 2 To solve the above problems, the present application provides a cleaning device 10, comprising: a cleaning mechanism 20, comprising a support body 21, a cleaning member 30 is provided at the front top of the support body 21; at least two driving mechanisms 40, at least two driving mechanisms 40 are detachably mounted on the left and right sides of the support body 21, and each driving mechanism 40 is provided with a lifting assembly 41. The following embodiments take the cleaning device 10 cleaning a wind turbine tower 50 as an example.

[0028] In the cleaning device 10, the cleaning part 30 is arranged at the front top of the bracket body 21. The cleaning part 30 can clean the wind power tower 50. The tower is the support frame of the wind turbine, and there are dust pollution, oil pollution, corrosion and rust problems, and oil pollution is particularly serious. As the working time of the wind turbine increases, the oil pollution will become more serious, which not only affects the beauty of the tower, but also causes serious damage to the paint surface of the tower, making the tower surface more prone to corrosion and rust. Large-area oil pollution will make the entire tower surface without paint protection, which will reduce the anti-corrosion performance of the tower, shorten the service life, stress deformation, reduce the structural strength, and cause the risk of tower collapse. Therefore, tower cleaning is very important. Placing the cleaning member 30 in front of the bracket body 21 enables the cleaning member 30 to directly clean the wind turbine tower 50. Placing the cleaning member 30 at the top of the front enables the cleaning device 10 to clean the root of the wind turbine tower 50, thereby cleaning the root of the nacelle of the wind turbine tower 50 and improving the cleaning effect of the cleaning device 10 on the wind turbine tower 50. In some embodiments, the cleaning device 10 includes at least two driving mechanisms 40, and the driving mechanism 40 can be used to drive the cleaning mechanism 20 to move on the wind turbine tower 50. In some embodiments, the driving mechanism 40 can be symmetrically arranged on the left and right sides of the cleaning mechanism 20, respectively, so that the cleaning mechanism 20 can stably move on the wind turbine tower 50. In some embodiments, the driving mechanism 40 is provided with a lifting assembly 41, which has the function of adjusting the height. The lifting assembly 41 can adjust the position of the driving mechanism 40 and drive the cleaning mechanism 20 to move. The drive mechanism 40 is set to a detachable structure, which can be modularly disassembled and transported to the work site, and quickly assembled and put into use, so as to realize a convenient, fast, modular disassembly and assembly transportation method. Compared with the traditional integrated mechanism that cannot be quickly disassembled and transported to the site, cannot replace different devices in time, cannot clean the root position of the wind turbine tower 50 cabin, and cannot adapt to the change of the upper and lower diameters of the tower, resulting in inconvenient transportation, small cleaning range, incomplete cleaning position, poor cleaning effect, low cleaning efficiency and other problems, the embodiment of the present application can realize the modular disassembly of the cleaning device 10, while improving the cleaning effect of the cleaning device 10, thereby improving the cleaning efficiency.

[0029] In some embodiments, the cleaning member 30 includes a roller brush 31, a rotating shaft 32 and a coupling 33. The rotating shaft 32 extends in the left-right direction of the support body 21. The roller brush 31 is fixed on the rotating shaft 32. The rotating shaft 32 is rotatably connected to the coupling 33. The coupling 33 is fixed to the support body 21. The support body 21 is connected to the driving mechanism 40. The support body 21 can move under the drive of the driving mechanism 40, so as to clean different positions of the wind turbine tower 50. In some embodiments, the coupling 33 is fixed to the support body 21, the rotating shaft 32 is rotatably connected to the coupling 33, and the roller brush 31 is fixed on the rotating shaft 32. It can be seen that the roller brush 31 can clean the wind turbine tower 50 under the drive of the driving mechanism 40. In some embodiments, the side of the roller brush 31 close to the wind turbine tower 50 is set to an arc shape. In some embodiments, the arc surface of the roller brush 31 is adapted to the arc surface of the outer surface of the wind turbine tower 50. In some embodiments, the top of the roller brush 31 is higher than the bracket body 21. Such a structural setting enables the roller brush 31 to clean the root of the wind turbine tower 50, thereby cleaning the root position of the nacelle of the wind turbine tower 50. In some embodiments, the roller brush 31 can rotate around the rotating shaft 32, so that when cleaning, the rotatable brush can clean the wind turbine tower 50 more comprehensively. In some embodiments, the roller brush 31 uses a brush with rich bristles to improve the cleaning effect and cleaning efficiency of the cleaning device 10. In some embodiments, the roller brush 31 is set at the uppermost position of the cleaning device 10, so as to achieve the cleaning of the root position of the nacelle of the wind turbine tower 50, thereby improving the cleaning efficiency of the cleaning device 10.

[0030] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the cleaning component 30 is detachably mounted on the bracket body 21. The cleaning component 30 is set as a detachable structure. When cleaning different wind turbine towers 50, different cleaning components 30 can be replaced according to the situation. Cleaning components 30 of different diameters can be switched according to wind turbine towers 50 of different diameters. Cleaning components 30 of different diameters can be effectively fitted to the outer walls of different wind turbine towers 50, thereby achieving the cleaning of the walls of wind turbine towers 50 with different curvature radii. At the same time, the cleaning component 30 is set as a detachable structure to facilitate the maintenance of the cleaning device 10 and the regular replacement of the cleaning component 30, such as regular replacement of the roller brush 31, which can improve the cleaning effect of the cleaning device 10 and thereby improve the cleaning efficiency of the cleaning device 10.

[0031] In some embodiments, a control box 22 is provided in the support body 21, and a hoist 411 is provided in the lifting assembly 41. The mechanical equipment for transportation by changing potential energy, the hoist 411 generally has a strong lifting capacity. The transportation process is completed by dragging the flexible steel rope and the transported goods up and down by a power machine, and the hoist 411 is used to connect and act on the steel rope 413 to provide lifting force for the cleaning device 10. In some embodiments, the steel rope 413 can be a phosphate-coated steel wire rope, a galvanized steel wire rope, a stainless steel wire rope or a smooth steel wire rope. In some embodiments, a power supply is provided in the control box 22, and the power supply is electrically connected to the hoist 411 to realize power supply. The control box 22 is installed at the lower end of the cleaning mechanism 20, and the output end of the control box 22 is connected to the input end of the drive mechanism 40 to control the drive mechanism 40. The lifting assembly 41 can make the cleaning device 10 rise or fall. In some embodiments, a power supply is provided in the control box 22, and the power supply is electrically connected to the hoist 411 to realize power supply, the steel rope 413 passes through the pulley 410, and the hoist 411 acts on the steel rope 413 to provide lifting force to the cleaning device 10, which is used to lift the entire cleaning device 10. By adjusting the lifting of the cleaning device 10, the cleaning device 10 can be moved on the wind power tower 50 to achieve cleaning work at different parts. In some embodiments, a pulley 410 is also provided in the lifting assembly 41, and the pulley 410 is located above the hoist 411, and the pulley 410 is used to pass the steel rope 413. The pulley 410 is a small wheel with a groove around the periphery that can rotate around the axis. A mechanical structure that can rotate around the central axis is composed of a grooved disc that can rotate around the central axis and a flexible cable that crosses the disc. In some embodiments, the front side of the lifting assembly 41 is provided with an adsorption member 412 that can be rotated laterally relative to the bracket body 21. The adsorption member 412 is installed at the front end of the driving mechanism 40 and has a permanent magnet with strong adsorption force, which is used to adsorb the cleaning device 10 on the working surface of the tower. In some embodiments, the adsorption member 412 can be an electric permanent magnetic chuck, and the electric permanent magnetic chuck has two rare earth permanent magnetic materials-neodymium iron boron and aluminum nickel cobalt. The electric permanent magnet uses the different characteristics of these two permanent magnetic materials to control and convert the distribution of its internal magnetic circuit through the electric control system, so that the permanent magnetic field is self-balanced inside the system, which is characterized by a demagnetized relaxation state, or released to the working magnetic pole surface of the electric permanent magnet, which is characterized by a magnetized clamping state. An electromagnet is a device that generates electromagnetism when powered on, which converts electrical energy into magnetic energy, and then converts magnetic energy into kinetic energy. It is mainly a conductive winding that matches its power is wound around the outside of the iron core. This coil with current flowing through it has magnetism like a magnet. An electro-permanent magnet is a magnet that can be controlled by electricity. Its main materials are neodymium iron boron and aluminum nickel cobalt. The electromagnet is magnetic when it is powered on and loses its magnetism when it is powered off. An electro-permanent magnet only needs electricity when it is magnetized or demagnetized, that is, when it is attracted or released. It does not need electricity when it is used in between and can maintain its magnetic force permanently. In some embodiments, the adsorbent 412 is a permanent magnet.The adsorption member 412 of the driving mechanism 40 is adsorbed on the working surface of the tower, and the cleaning device 10 is lifted on both sides by the steel rope 413, so that the cleaning device 10 moves slowly from bottom to top along the working surface and cleans.

[0032] See also Figure 1 The bottom of the bracket body 21 is provided with a distance sensor 23 with a detection direction facing the front of the bracket body 21. In some embodiments, the distance sensor 23 can be an ultrasonic sensor, which is a sensor developed using the characteristics of ultrasonic waves. Ultrasonic waves are mechanical waves with a vibration frequency higher than that of sound waves. They are generated by the vibration of the transducer chip under the excitation of voltage. They have the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can become rays and propagate in a directional manner. Ultrasonic waves have great penetrating power for liquids and solids, especially in solids that are opaque to sunlight, and can penetrate a depth of tens of meters. When ultrasonic waves encounter impurities or interfaces, they will produce significant reflections to form echoes, and when they encounter moving objects, they can produce a Doppler effect. In some embodiments, the distance sensor 23 can also be a laser distance sensor. When the laser sensor is working, the laser diode first aims at the target and emits laser pulses. After being reflected by the target, the laser is scattered in all directions. Part of the scattered light returns to the sensor receiver, and is imaged onto the avalanche photodiode after being received by the optical system. The avalanche photodiode is an optical sensor with an internal amplification function, so it can detect extremely weak light signals. By recording and processing the time from when the light pulse is emitted to when it is received, the target distance can be determined. The distance sensor 23 can also be an infrared distance sensor. The infrared distance sensor uses the principle that the intensity of the reflection of the infrared signal at different distances from the obstacle is also different to detect the distance of the obstacle. In some embodiments, a plurality of universal wheels 24 are provided at the bottom of the bracket body 21. The universal wheels 24 can facilitate the movement of the cleaning mechanism 20 on the ground and are the main moving parts of the cleaning mechanism 20. The universal wheels 24 are provided on the cleaning device 10 to increase the movement speed of the cleaning device 10 on the ground. The staff can push the cleaning device 10 to move the cleaning device 10 on the ground, which is convenient for the transportation of the cleaning device 10.

[0033] See also Figure 1 , Figure 2 and Figure 3In some embodiments, the cleaning device 10 adopts a detachable transportation method and replaces different cleaning parts 30. The cleaning mechanism 20 and at least two driving mechanisms 40 can be disassembled and separated separately, transported to the site, and reassembled for use after arriving at the site, thereby reducing transportation costs, facilitating disassembly and assembly, and facilitating maintenance. At the same time, for towers with different curvature radii, the cleaning mechanism 20 containing roller brushes 31 of different diameters can be replaced, which can effectively fit with different tower outer walls to achieve the cleaning of the wall surface of the wind turbine tower 50 with different curvature radii. The traditional cleaning robot sets the roller brush 31 in the middle position of the working device. When cleaning the root position of the cabin of the wind turbine tower 50, the upper end of the roller brush 31 is blocked by the working device, so the root position of the cabin cannot be cleaned at all. Now set the roller brush 31 at the uppermost position of the cleaning mechanism 20, and the root position of the cabin of the wind turbine tower 50 will be cleaned. Figure 3The schematic diagram shows the working state of the driving mechanism 40 of the cleaning device 10 on the tower wall at 2.0m, 2.5m, 3.0m, and 4.5m of the diameter of the wind turbine tower 50. When the cleaning device 10 is close to the wall of the wind turbine tower 50, the adsorption part 412 of the driving mechanism 40 will be adsorbed on the working surface of the tower, and the cleaning device 10 will be lifted on both sides by steel ropes 413, so that it can slowly move and clean along the working surface from bottom to top. In one embodiment, two driving mechanisms 40 are used, namely a left driving mechanism and a right driving mechanism. The left driving mechanism is installed at the left end of the cleaning mechanism 20, and the right driving mechanism is installed at the right end of the cleaning mechanism 20, and both provide walking power for the cleaning device 10. The cleaning mechanism 20 includes a cleaning part 30, a control box 22, a distance sensor 23, a universal wheel 24, etc. The cleaning part 30 is provided at the front top of the bracket body 21. The top of the roller brush 31 is higher than the bracket body 21, and can clean the root position of the nacelle of the wind turbine tower 50. The control box 22 is installed at the lower end of the cleaning part 30. The output end of the control box 22 is connected to the input end of the driving mechanism 40 to control the driving mechanism 40. The distance sensor 23 is installed at the lower end of the cleaning part 30 to detect the distance from the working surface of the wind tower. The bracket body 21 is the main supporting component of the cleaning mechanism 20, and the universal wheel 24 is the main moving component of the cleaning mechanism 20. The cleaning part 30, the control box 22, the distance sensor 23, and the universal wheel 24 are all installed on the bracket body 21. The cleaning part 30 includes a roller brush 31, a rotating shaft 32 and a coupling 33. The roller brush 31 is fixed to the rotating shaft 32, and both ends of the rotating shaft 32 are fixed to the bracket body 21 through the coupling 33. The left driving mechanism includes a hoist 411, a pulley 410, a steel rope 413, and an adsorbent 412. The right driving mechanism has the same structure as the left driving mechanism. The hoist 411 is installed at the lower end of the left driving mechanism to provide a lifting force. The pulley 410 is installed at the upper end of the left driving mechanism. The steel rope 413 passes through the pulley 410 and is used together to lift the entire cleaning device 10. The adsorbent 412 is installed at the front end of the left driving mechanism and has a permanent magnet with strong adsorption force, which is used to adsorb the robot to the working surface of the tower. Through the above-mentioned cleaning process, the modular disassembly of the cleaning device 10 can be achieved, and at the same time, the cleaning effect of the cleaning device 10 is improved, thereby improving the cleaning efficiency.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
