Description

Technical Field

[0001] The invention belongs to the technical field of wind power equipment cleaning devices, in particular to a wind power tower oil cleaning device. Background Art

[0002] Wind turbine tower oil cleaning equipment is a mechanical equipment specially used to clean oil stains on the surface of wind turbine towers. It mainly includes wall-climbing robots (or high-pressure cleaning machines), cleaning components, sewage recovery devices and other parts. It can use high-pressure water, detergents or dry ice and other media to efficiently and environmentally remove oil stains, dirt and stubborn attachments on the surface of the tower, realizing automated and intelligent cleaning operations.

[0003] In the prior art, the equipment reaches the oil stain location on the tower by climbing up by itself, and at the same time, the nozzle sprays the prepared cleaning liquid on the oil stain so that the oil stain is fully soaked. The cleaning brush head brushes off the oil stain during the rotation process, and then the recovery device is used to collect the cleaning liquid with oil stains to prevent it from flowing freely and causing secondary pollution. After a series of cleaning processes, the oil stains on the surface of the wind turbine tower are effectively removed.

[0004] There are still some problems in the actual application of the above scheme. The existing equipment can complete the cleaning of oil stains on the surface of wind turbine towers. However, since wind turbine towers are usually in an outdoor environment, they will be affected by various factors such as sunlight and temperature changes, causing the oil stains to gradually change from a fluid form to a semi-fluid form. At this time, the detergent sprayed by the equipment is simply attached to the outer layer of the oil stains, but cannot penetrate into the interior. Since the detergent cannot penetrate into the interior of the oil stains, each cleaning can only remove the part of the detergent attached to the outer layer of the oil stains. In order to achieve the ideal cleaning effect, the same area needs to be cleaned multiple times, which will greatly reduce the cleaning efficiency and increase the cost and time of cleaning. Secondly, due to the popularity of wind power, there are also a large number of wind turbine towers in desert areas. However, due to the large amount of wind and sand in desert areas, when mixed with oil stains, these solid particles will remain in the oil stains and increase the hardness of the oil stains when the oil stains solidify. At this time, when parallel piercing is performed by pressing the piercing mechanism, these solid particles will damage the needle, which will reduce the service life of the equipment and the adaptability of the equipment to cleaning different types of oil stains.

[0005] To this end, the present invention provides a wind turbine tower oil cleaning device. Summary of the invention

[0019] 1. The oil stain cleaning device for wind turbine tower described in the present invention, when the moving plate moves along the guide of the inner cavity of the protection frame, it will synchronously drive all the components in the inner cavity of the moving plate to move synchronously. When the bottom of the moving needle contacts the surface of the oil stain, the moving plate will continue to move toward the surface of the wind turbine tower, and pierce the oil stain through the bottom of the moving needle while moving. When the bottom of the local moving needle contacts the outer ring surface of the wind turbine tower, the moving needle will move upward along the guide of the inner cavity of the piston cylinder, and squeeze the inner cavity of the piston cylinder while moving. The reciprocating spring in the cavity can reduce the damage to the outer ring surface of the wind turbine tower during parallel insertion through the arc structure at the bottom of the moving needle and the setting of the reciprocating spring. When several groups of moving needles complete the puncturing of the oil on the outer ring surface of the wind turbine tower, the wall-climbing trolley will continue to move with all the parts, and spray the oily parts that have been punctured with detergent through the atomizing nozzle.

Since the toggle rod is sleeved inside the annular buckle, when the bottom of the annular buckle contacts the upper part of the toggle rod, it drives the toggle rod, the piston cylinder, the reciprocating spring and the moving needle to rotate around the rotating ball. At this time, the downward pressure in the downward pressure piercing mechanism can make the moving needle in an inclined state to pierce the oil mixed with impurities. When piercing obliquely, the direction of force is oblique.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1: Figures 1 to 8As shown, a wind power tower oil cleaning device according to an embodiment of the present invention comprises a wall-climbing trolley 1, a cleaning assembly 2 is arranged on the side of the wall-climbing trolley 1, and the cleaning assembly 2 comprises a support frame 201, the support frame 201 is fixedly connected to the side of the wall-climbing trolley 1, a protection frame 202 is fixedly connected to one end of the support frame 201, a cavity is arranged inside the protection frame 202, a detergent containing box 203 is fixedly connected to the upper part of the cavity of the protection frame 202, an atomizing nozzle 204 is fixedly connected to the bottom of the detergent containing box 203, the atomizing nozzle 204 penetrates the bottom of the detergent containing box 203, and a one-way valve is arranged between the detergent containing box 203 and the atomizing nozzle 204, a rotating cleaning brush 205 is arranged in the inner cavity of the protection frame 202, the top of the rotating cleaning brush 205 is connected to the motor output shaft, and the motor is fixedly connected to the side wall of the detergent containing box 203, and a downward pressing piercing mechanism 3 is arranged inside the cleaning assembly 2;

[0036] The downward-pressing piercing mechanism 3 includes a bidirectional screw 302 rotatably arranged in the inner cavity of the protective frame 202, a movable plate 309 is fixedly arranged at the lower part of the bidirectional screw 302, and a plurality of movable needles 314 are slidably arranged inside the movable plate 309. The reciprocating motion of the movable plate 309 can drive the movable needles 314 to reciprocate, so that holes can be pierced in the oil stains attached to the outer ring surface of the wind turbine tower, thereby improving the penetration efficiency of the detergent and thus improving the overall cleaning efficiency.

[0037] Specifically, the existing equipment can complete the cleaning of oil stains on the surface of wind turbine towers. However, since wind turbine towers are usually located in an outdoor environment, they will be affected by various factors such as sunlight and temperature changes, causing the oil stains to gradually change from a fluid state to a semi-fluid state. At this time, the cleaning agent sprayed by the equipment simply adheres to the outer layer of the oil stains and cannot penetrate deep into the interior. Since the cleaning agent cannot penetrate deep into the oil stains, each cleaning can only remove the part of the outer layer of the oil stains where the cleaning agent adheres. In order to achieve the ideal cleaning effect, the same area needs to be cleaned multiple times, which will greatly reduce the cleaning efficiency and increase the cost and time of cleaning.

[0038] Therefore, the present invention solves this problem by setting a corresponding structure. The oil cleaning device for wind turbine tower described in the present invention, when it is necessary to clean the oil on the wind turbine tower, start the wall climbing trolley 1 with the cleaning component 2 to move from the bottom to the top along the outer ring surface of the wind turbine tower, and open the one-way valve between the detergent containing box 203 fixed in the inner cavity of the protection frame 202 and the atomizing nozzle 204 while moving. At this time, the detergent stored in the detergent containing box 203 will be sprayed onto the outer ring surface of the wind turbine tower through the atomizing nozzle 204, and the motor fixed on the side wall of the detergent containing box 203 will be started while spraying the detergent. At this time, the rotating cleaning brush 205 fixed to the motor output shaft will rotate, thereby achieving the cleaning effect. However, since the wind turbine tower is usually in an outdoor environment, it will be affected by various factors such as sunlight and temperature changes. The influence of makes the oil stain gradually change from a fluid form to a semi-fluid form. At this time, the detergent sprayed by the equipment is simply attached to the outer layer of the oil stain and cannot penetrate into the inside. Since the detergent cannot penetrate into the inside of the oil stain, each cleaning can only remove the part of the outer layer of the oil stain where the detergent is attached. In order to achieve the ideal cleaning effect, the same area needs to be cleaned multiple times, which will greatly reduce the cleaning efficiency, thereby increasing the cost and time of cleaning. Before spraying, the bidirectional screw 302 will rotate, and at the same time, it will drive the moving plate 309 to move linearly. When the moving plate 309 moves linearly, it will drive several moving needles 314 inside it to move synchronously, so that the oil stain attached to the outer ring surface of the wind turbine tower can be pierced, thereby improving the penetration efficiency of the detergent, thereby improving the overall cleaning efficiency.

[0039] Embodiment 2: Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0040] like Figure 3 As shown, the downward pressing hole-piercing mechanism 3 described in this embodiment includes a first micro bidirectional motor 301, and the first micro bidirectional motor 301 is fixedly connected to the side wall of the protection frame 202. The output shaft of the first micro bidirectional motor 301 is fixedly connected to a bidirectional screw 302, and the outer ring surface of the bidirectional screw 302 is threadedly connected to a displacement block 303, and the top of the displacement block 303 is fixedly connected to a guide block 304. A guide groove 305 is opened at the top of the inner cavity of the protection frame 202, and the guide block 304 is slidably connected to the inside of the guide groove 305.

[0041] Specifically, when the oil stains on the outer ring surface of the wind turbine tower are thick, start the first micro bidirectional motor 301. At this time, the output shaft of the first micro bidirectional motor 301 will drive the bidirectional screw 302 fixed to it to rotate, and at the same time drive the two groups of displacement blocks 303 on its outer ring surface to move synchronously. Since the guide block 304 on the top of the displacement block 303 slides inside the guide groove 305, when the bidirectional screw 302 rotates, it will drive the two groups of displacement blocks 303 to perform relative linear motion along the guide of the guide groove 305, thereby providing corresponding power support for subsequent equipment.

[0042] like Figure 4 As shown, the displacement block 303 in this embodiment is fixedly connected to a fixed block 306 at the bottom, and a connecting rod 307 is rotatably connected inside the fixed block 306. A base 308 is provided at one end of the connecting rod 307, and one end of the connecting rod 307 is rotatably connected to the inside of the base 308. A movable plate 309 is fixedly connected to the bottom of the base 308.

[0043] Specifically, when the two groups of displacement blocks 303 move synchronously toward the middle of the bidirectional screw 302 along the guide of the guide groove 305, the fixed block 306 fixed at the bottom of the displacement block 303 will also move synchronously, and drive the connecting rod 307 to move synchronously while moving. However, since one end of the connecting rod 307 is rotated inside the base 308, when the fixed block 306 follows the displacement block 303 to move in a straight line, the connecting rod 307 will push the base 308 and the movable plate 309 fixed to the base 308 to move along the guide of the inner cavity of the protective frame 202.

[0044] like Figure 5 and Figure 6 As shown, in this embodiment, an inner cavity is defined inside the movable plate 309, a limiting hole 310 is defined through the bottom of the inner cavity of the movable plate 309, a rotating ball 311 is rotatably connected inside the limiting hole 310, a piston cylinder 312 is fixedly connected to the bottom of the rotating ball 311, an inner cavity is defined inside the piston cylinder 312, a reciprocating spring 313 is fixedly connected to the top of the inner cavity of the piston cylinder 312, a moving needle 314 is fixedly connected to the other end of the reciprocating spring 313, the moving needle 314 is slidably connected in the inner cavity of the piston cylinder 312, and a toggle rod 315 is fixedly connected to the top of the rotating ball 311.

[0045] Specifically, when the moving plate 309 moves along the guide of the inner cavity of the protection frame 202, it will synchronously drive all the components in the inner cavity of the moving plate 309 to move synchronously. When the bottom of the moving needle 314 contacts the surface of the oil stain, the moving plate 309 will continue to move toward the surface of the wind turbine tower, and pierce the oil stain through the bottom of the moving needle 314 while moving. When the bottom of the local moving needle 314 contacts the outer ring surface of the wind turbine tower, the moving needle 314 will move upward along the guide of the inner cavity of the piston cylinder 312, and squeeze the inner cavity of the piston cylinder 312 while moving. The reciprocating spring 313, through the arc structure at the bottom of the moving needle 314 and the setting of the reciprocating spring 313, can reduce the damage to the outer ring surface of the wind turbine tower during parallel insertion. When several groups of moving needles 314 complete the puncturing of the oil stains on the outer ring surface of the wind turbine tower, the wall-climbing trolley 1 will continue to move with all the parts, and spray the oil stains that have been punctured with detergent through the atomizing nozzle 204. At this time, the detergent will enter the junction of the wind turbine tower and the oil stains through the punctured holes, thereby improving the penetration efficiency of the detergent, thereby improving the overall cleaning efficiency.

[0046] like Figure 7 As shown, the interior of the downward pressing hole-piercing mechanism 3 described in this embodiment is provided with an adjustable mechanism 4 with adjustable angle, and the adjustable mechanism 4 includes a second micro bidirectional motor 401, and the second micro bidirectional motor 401 is fixedly connected to the interior of the movable plate 309, and the output shaft of the second micro bidirectional motor 401 is fixedly connected to the first rotating shaft 402, and the outer ring surface of the first rotating shaft 402 is transmission-connected to the conveyor belt 403, and the conveyor belt 403 is internally rotatably connected to the second rotating shaft 404, and both ends of the second rotating shaft 404 and both ends of the first rotating shaft 402 are rotatably connected to the side wall of the inner cavity of the movable plate 309.

[0047] like Figure 8 As shown, in this embodiment, a reciprocating plate 405 is fixedly connected to the bottom of the conveyor belt 403 , and a ring buckle 406 is fixedly connected to the bottom of the reciprocating plate 405 . The ring buckle 406 is sleeved on the top of the toggle rod 315 .

[0048] Specifically, when encountering oily dirt mixed with impurities, the second micro bidirectional motor 401 is started, and the second micro bidirectional motor 401 drives the first rotating shaft 402 fixed to its output shaft to rotate, and drives the conveyor belt 403 on its outer ring surface to transmit during the rotation, and the second rotating shaft 404 rotating inside the conveyor belt 403 rotates at this time, and when the conveyor belt 403 transmits, it drives the reciprocating motion plate 405 at the bottom thereof to perform synchronous horizontal displacement, and when the displacement occurs, it drives the annular buckle 406 to perform synchronous movement, and since the toggle rod 315 is sleeved inside the annular buckle 406, when the bottom of the annular buckle 406 contacts the upper part of the toggle rod 315 , it will drive the toggle rod 315, the piston cylinder 312, the reciprocating spring 313 and the moving needle 314 to rotate around the rotating ball 311. At this time, the downward pressure in the downward pressure piercing mechanism 3 can make the moving needle 314 in an inclined state to pierce the oil mixed with impurities. When the oblique piercing is made, the direction of the force is oblique. When the needle hits a solid particle, the oblique force can make the moving needle 314 slide along the edge of the particle or push the particle away, thereby avoiding damage to the moving needle 314 caused by solid impurities in the oil, thereby extending the service life of the equipment. Secondly, by adjusting the inclination angle of the moving needle 314 for piercing the oil, the applicability of the equipment can be improved.

[0049] Working principle: when the oil stain on the outer ring surface of the wind turbine tower is thick, start the first micro bidirectional motor 301. At this time, the output shaft of the first micro bidirectional motor 301 will drive the bidirectional screw 302 fixed to it to rotate, and at the same time, it will drive the two groups of displacement blocks 303 on its outer ring surface to move synchronously. Since the guide block 304 on the top of the displacement block 303 slides inside the guide groove 305, when the bidirectional screw 302 rotates, it will drive the two groups of displacement blocks 303 to move in a relative straight line along the guide of the guide groove 305, thereby providing corresponding power support for subsequent equipment.

[0050] When the two groups of displacement blocks 303 move synchronously toward the middle of the bidirectional screw 302 along the guide of the guide groove 305, the fixed block 306 fixed at the bottom of the displacement block 303 will also move synchronously, and at the same time drive the connecting rod 307 to move synchronously, but because one end of the connecting rod 307 is rotated inside the base 308, when the fixed block 306 follows the displacement block 303 to move in a straight line, the connecting rod 307 will push the base 308 and the movable plate 309 fixed to the base 308 to move along the guide of the inner cavity of the protective frame 202.

[0051] When the movable plate 309 moves along the guide of the inner cavity of the protection frame 202, all the components in the inner cavity of the movable plate 309 will be synchronously driven to move synchronously. When the bottom of the movable needle 314 contacts the surface of the oil stain, the movable plate 309 will continue to move toward the surface of the wind turbine tower, and pierce the oil stain through the bottom of the movable needle 314 while moving. When the bottom of the local movable needle 314 contacts the outer ring surface of the wind turbine tower, the movable needle 314 will move upward along the guide of the inner cavity of the piston cylinder 312, and squeeze the inner cavity of the piston cylinder 312 while moving. The reciprocating spring 313, through the arc structure at the bottom of the moving needle 314 and the setting of the reciprocating spring 313, can reduce the damage to the outer ring surface of the wind turbine tower during parallel insertion. When several groups of moving needles 314 complete the puncturing of the oil stains on the outer ring surface of the wind turbine tower, the wall-climbing trolley 1 will continue to move with all the components, and spray the oil stains that have been punctured with detergent through the atomizing nozzle 204. At this time, the detergent will enter the junction of the wind turbine tower and the oil stains through the punctured holes, thereby improving the penetration efficiency of the detergent, thereby improving the overall cleaning efficiency.

[0052] When encountering oil contamination mixed with impurities, the second micro bidirectional motor 401 is started, and the second micro bidirectional motor 401 will drive the first rotating shaft 402 fixed to its output shaft to rotate, and drive the conveyor belt 403 on its outer ring surface to transmit during the rotation, and the second rotating shaft 404 rotating inside the conveyor belt 403 will rotate at this time, and when the conveyor belt 403 is transmitting, it will drive the reciprocating motion plate 405 at the bottom thereof to perform synchronous horizontal displacement, and during the displacement, it will synchronously drive the annular buckle 406 to perform synchronous movement, and since the toggle rod 315 is sleeved inside the annular buckle 406, the bottom of the annular buckle 406 and the toggle rod 315 are in contact with each other. When the upper part of the movable rod 315 contacts, it will drive the toggle rod 315, the piston cylinder 312, the reciprocating spring 313 and the moving needle 314 to rotate around the rotating ball 311, and pierce the oil mixed with impurities while moving. When the piercing is oblique, the direction of the force is oblique. When the needle touches a solid particle, the oblique force can make the moving needle 314 slide along the edge of the particle or push the particle away, thereby avoiding damage to the moving needle 314 caused by solid impurities in the oil, thereby extending the service life of the equipment. Secondly, by adjusting the inclination angle of the moving needle 314 for piercing the oil, the applicability of the equipment can be improved.
