Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic power generation, and specifically to a cleaning device for a wind power column. Background Art

[0002] Wind energy is a renewable clean energy. Nowadays, both internationally and domestically, great progress has been made in the utilization of wind energy, whether in theoretical research or application. In a wind turbine generator set, the main function of the tower barrel is to serve as a frame for supporting the generator. It not only needs to have a certain height to enable the blades to operate at a more reasonable position, but also good cleaning can improve the anti-corrosion performance of the tower barrel and greatly extend the service life of the tower barrel.

[0003] The Chinese patent CN111156138A, authorized and announced on May 19, 2020, discloses a cleaning device for a wind power column. Among them, it includes a sleeve, a flexible drive mechanism, and a cleaning mechanism. The support frame in the flexible drive mechanism is installed in the sleeve through an electric linear cylinder. Sliders are respectively installed on both sides of the end of the support frame. The roller body is rotatably installed on the slider through a universal joint coupling, and connecting rods are respectively arranged in the roller body. The connecting rods are connected through a universal joint coupling. A flexible belt is sleeved on the roller body. A push rod is movably installed on the bottom plate, and the end of the push rod contacts the inner side surface of the flexible belt. Two cleaning mechanisms are respectively installed at the ends of the two flexible drive mechanisms. In the above application document, when the device is used on a variable-diameter circular tower-shaped wind power column, since the radius of the cleaning mechanism at the top is fixed and the length of the brush is fixed, the device cannot perform cleaning work on the circular tower-shaped wind power column. At the same time, part of the dust generated by cleaning will directly fall into the device, which will have a certain impact on the internal components of the device after long-term use.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment 1, please refer to Figures 1-4 , A wind power generation column cleaning device, comprising: The outer shell 100 has two bolt mounting plates with a fixing function fixedly connected to the front side of the outer shell 100. By setting the bolt mounting plates, the two outer shells 100 can be fixedly closed. Four rotating shaft blocks are fixedly connected to the rear side of the outer shell 100. By setting the rotating shaft blocks, the rear sides of the two outer shells 100 are kept hinged, so that the device can be opened when the cleaning work is completed, facilitating the installation and disassembly of the device. An inner support plate 200 is fixedly connected to the inside of the outer shell 100. A flexible driving device is movably connected to the inside of the inner support plate 200. By setting the flexible driving device, when the device moves up and down the side of the wind power column, the flexible driving device automatically deflects according to the shape of the column side, making the device move more stably when moving up and down. The inner support plate 200 is fixedly connected to the outer shell 100 through the first fixing block 400. A first support rod 300 is fixedly connected to the top of the inner support plate 200. A circular slide rail 500 is fixedly connected to the top of the first inner support rod 300. A friction wheel 600 is movably connected to the front side of the circular slide rail 500. By setting the friction wheel 600, the circular hydraulic block 805 inside the circular slide rail 500 rotates following the rotation of the friction wheel 600, making the device clean the wind power column more efficiently. A circular hydraulic block 805 is slidably connected inside the circular slide rail 500. The outer side of the circular hydraulic block 805 is movably connected to the outer side of the friction wheel 600. A rotating shaft 700 is penetrated and fixedly connected inside the friction wheel 600. The friction wheel 600 is movably connected to the circular hydraulic block 805 through a square groove opened on the outer surface of the circular slide rail 500. A circular groove 806 is opened at the center of the circular hydraulic block 805. A first hydraulic block 801 is fixedly connected to the surface of the circular groove 806. The number of the first hydraulic blocks 801 is six, and each first hydraulic block 801 is circumferentially distributed on the surface of the circular groove 806. The length of the first push block 802 is greater than the length of the telescopic brush bristles 804. The number of the first push blocks 802 is six, and each first push block 802 is circumferentially distributed on the surface of the circular groove 806. The number of the telescopic brush bristles 804 is thirty. Every two telescopic brush bristles 804 form a group, and each group of telescopic brush bristles 804 is circumferentially distributed on the inner side surface of the circular hydraulic block 805. The first push block 802 is slidably connected to the outer side of the first hydraulic block 801. One end of a first hose 803 is fixedly connected to the side surface of the first hydraulic block 801, and the other end of the first hose 803 is fixedly connected to the inner side of the circular hydraulic block 805. By setting the first hose 803, the inside of the circular hydraulic block 805 is communicated with the inside of the first hydraulic block 801. A plurality of telescopic brush bristles 804 are slidably connected to the upper and lower inner sides of the circular hydraulic block 805. An automatic water spraying assembly 900 is movably connected to the top of the circular hydraulic block 805. A scraping plate assembly 1000 is movably connected to the inside of the automatic water spraying assembly 900. By setting the telescopic brush bristles 804, when the device moves on the variable-diameter circular tower-shaped wind power column, the length of the telescopic brush bristles 804 changes correspondingly, making the telescopic brush bristles 804 closely adhere to the side surface of the wind power column, increasing the usage range of the device.

[0021] During use, when the diameter of the wind power column changes on the side, due to the diameter change, the first push block 802 moves outwards to be flush with the column surface, causing the first hydraulic block 801 to be compressed. The internal pressure of the first hydraulic block 801 is transmitted through the first hose 803 to the inside of the annular hydraulic block 805, causing the annular hydraulic block 805 to be compressed, and the telescopic brush bristles 804 are pushed outwards to be flush with the column surface. The telescopic brush bristles 804 are closely attached to the side of the wind power column, increasing the scope of use of the device. When the device moves in the reverse direction, the first push block 802 contracts inwards to be flush with the column surface, causing the first hydraulic block 801 to recover. The internal pressure of the first hydraulic block 801 is transmitted through the first hose 803 to the inside of the annular hydraulic block 805, causing the annular hydraulic block 805 to recover. As a result, the telescopic brush bristles 804 contract inwards to be flush with the column surface, and the telescopic brush bristles 804 are closely attached to the side of the wind power column, increasing the scope of use of the device.

[0022] Embodiment 2. Please refer to Figures 1-6 , on the basis of Embodiment 1, the automatic water spraying assembly 900 includes a second hose 901, a second hydraulic block 902, a second push block 903, a valve 904, a water spraying pipe 905, an annular water tank 906, a water injection port 907, and a second support rod 908. The side of the first hydraulic block 801 is fixedly connected to one end of the second hose 901, and the other end of the second hose 901 is fixedly connected to the side of the second hydraulic block 902. The second hose 901 is provided to make the inside of the first hydraulic block 801 communicate with the inside of the second hydraulic block 902.

The top of the water spraying pipe 905 is fixedly connected to an annular water tank 906. The annular water tank 906 is provided so that when the annular hydraulic block 805 rotates, the annular water tank 906 rotates together with the annular hydraulic block 805, thus not affecting the cleaning process.

The surface of the telescopic brush bristles 804 is provided with water spraying ports, and the inside of the telescopic brush bristles 804 communicates with the inside of the water spraying pipe 905 through a water pipe. Through the setting of the automatic water spraying assembly 900, when the diameter of the wind power column changes, the first hydraulic block 801 is compressed, and in cooperation with the second hydraulic block 902, the second push block 903, the valve 904, the water spraying pipe 905, the annular water tank 906, and the second hose 901, the water spraying ports inside the telescopic brush bristles 804 spray water onto the surface of the wind power column, improving the cleaning efficiency of the device.

[0023] In use, on the basis of the first embodiment, when the diameter of the wind power column changes, the first push block 802 moves outwards until it is flush with the column surface, compressing the first hydraulic block 801. The internal pressure of the first hydraulic block 801 is transmitted through the second hose 901 to the inside of the second hydraulic block 902, compressing the second hydraulic block 902. The second push block 903 is pushed downwards, gradually opening the valve 904. The water inside the annular water tank 906 is sprayed onto the surface of the wind power column through the water spray pipe 905 and the water spray nozzles inside the telescopic brush bristles 804, improving the cleaning efficiency of the device. When the device moves in the reverse direction, the first push block 802 moves inwards until it is flush with the column surface, restoring the first hydraulic block 801. The internal pressure of the first hydraulic block 801 is transmitted through the second hose 901 to the inside of the second hydraulic block 902, restoring the second hydraulic block 902. The second push block 903 slides upwards, gradually closing the valve 904, thereby achieving the effect of cyclic water spraying and improving the cleaning efficiency of the device.

[0024] Example 3, please refer to Figures 1-8, based on the first and second embodiments, the scraper assembly 1000 includes a third hose 1001, a third hydraulic block 1002, a third push block 1003, a second fixed block 1004, a chute 1005, and a scraper 1006. The side of the first hydraulic block 801 is fixedly connected to one end of the third hose 1001, and the other end of the third hose 1001 is fixedly connected to the side of the third hydraulic block 1002. The third hose 1001 is provided to communicate the inside of the third hydraulic block 1002 with the inside of the first hydraulic block 801. The inside of the third hose 1001 communicates with the inside of the third hydraulic block 1002, and the inside of the third hose 1001 communicates with the inside of the first hydraulic block 801. The bottom of the third hydraulic block 1002 is movably connected to a third push block 1003. The bottom of the third push block 1003 is fixedly connected to a second fixed block 1004. The side of the second fixed block 1004 is slidably connected to the scraper 1006 through the chutes 1005 opened on both sides of the scraper 1006. The chutes 1005 are provided to enable the scraper 1006 to slide along the direction of the chutes 1005. The number of scrapers 1006 is five, and each scraper 1006 is circumferentially distributed on the surface of the annular hydraulic block 805. The included angle between the side of each scraper 1006 and the top of the annular hydraulic block 805 is 45 degrees. The other side of the second fixed block 1004 is fixedly connected to the outside of the water spray pipe 905. The width of the chute 1005 is the same as the width of the second fixed block 1004. An arc-shaped opening is provided at the front end of the scraper 1006, and the arc of the arc-shaped opening is consistent with the side curvature of the wind power generation column. The arc-shaped opening is provided to make the front end of the scraper 1006 contact the side of the wind power generation column more completely, so that the swept ash can fall onto the surface of the scraper 1006 as much as possible, thereby reducing the impact of dust on the internal parts of the equipment. The rear end of the scraper 1006 extends outside the housing 100. Through the setting of the scraper assembly 1000, the dust generated by the telescopic brush bristles 804 scrubbing the surface of the wind power generation column is carried to the outside of the equipment by the scraper 1006, so that the dust will not directly fall into the equipment, thereby protecting the equipment.

[0025] In use, based on the first and second embodiments, when the diameter of the wind power column changes, the first push block 802 moves outward until it is flush with the column surface, compressing the first hydraulic block 801. The internal pressure of the first hydraulic block 801 is transmitted through the third hose 1001 to the inside of the third hydraulic block 1002, compressing the third hydraulic block 1002. The third push block 1003 moves downward, causing the second fixed block 1004 to slide with the scraper 1006 through the chute 1005, and the scraper 1006 moves obliquely upward until it contacts the surface of the wind power column. Thus, the dust generated by the telescopic brush bristles 804 scrubbing the surface of the wind power column is carried to the outside of the device by the scraper 1006, preventing the dust from directly falling into the device, thereby protecting the device. When moving in the reverse direction, the first hydraulic block 801 returns, and the internal pressure of the first hydraulic block 801 is transmitted through the third hose 1001 to the inside of the third hydraulic block 1002, causing the third hydraulic block 1002 to return. The third push block 1003 moves upward, causing the second fixed block 1004 to slide with the scraper 1006 through the chute 1005, and the scraper 1006 moves obliquely downward and remains in contact with the surface of the wind power column. Thus, the dust generated by the telescopic brush bristles 804 scrubbing the surface of the wind power column is carried to the outside of the device by the scraper 1006, preventing the dust from directly falling into the device, thereby protecting the device.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
