DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The two one-way liquid passage mechanisms 4 are arranged in opposite positions relative to the sealing seat 6. The one-way liquid passage mechanisms 4 are used for one-way liquid passage. A plurality of cleaning mechanisms 5 are arranged inside the driving mechanism 3, and the driving mechanism 3 can drive the plurality of cleaning mechanisms 5 to rotate.

[0031] The wear-reducing and shock-proof mechanism 2 includes a receiving groove 201, which provides an installation position, and the interior of the receiving groove 201 is filled with lubricating oil. The receiving groove 201 is opened inside the outer column 1, and the middle part of the outer column 1 is slidably connected with a movable column 202, which provides an installation position. The outer side of the movable column 202 is slidably connected with multiple butterfly-shaped springs 203, and the movable column 202 can limit the movement trajectory of the butterfly-shaped springs 203. The butterfly-shaped springs 203 can provide elastic force. Liquid holes 204 are opened on both sides of the butterfly-shaped springs 203, and the liquid holes 204 can pass liquid. Liquid grooves 205 are opened on both sides of the outer column 1. The liquid tank 205 can pass through the liquid, and a plurality of connecting holes 206 are provided on the inner walls on both sides of the outer column 1. The top of the top butterfly spring piece 203 is fixedly connected to the top column 207, and the bottom of the top column 207 is fixedly connected to the top of the movable column 202. The bottom of the bottom butterfly spring piece 203 is fixedly connected to the bottom inner wall of the receiving groove 201, and the butterfly spring piece 203 is slidably connected to the inside of the receiving groove 201. The outside of the top column 207 is slidably connected to the top of the outer column 1. The connecting hole 206 is connected to the receiving groove 201. The top of the outer column 1 is fixedly connected to the sealing ring 7, and the outside of the top column 207 is slidably connected to the inner side of the sealing ring 7. The top column 207 is After being squeezed, the movable column 202 can be driven to move downward, and the top column 207 can be used to squeeze the butterfly spring piece 203, so that the butterfly spring piece 203 is deformed. Under the reaction force of the butterfly spring piece 203, the butterfly spring piece 203 has elasticity. When the butterfly spring piece 203 is deformed, the lubricating oil inside the butterfly spring piece 203 can flow out from the inside of the liquid hole 204. At the same time, the liquid inside the receiving groove 201 increases and enters the inside of the liquid groove 205 through the connecting hole 206, and then enters the driving mechanism 3 through the liquid groove 205. When the butterfly spring piece 203 rebounds, it can drive the top column 207 to move upward, and then It can drive the movable column 202 to move upward, so that the liquid is squeezed into the interior of the liquid groove 205, and the liquid in the liquid groove 205 is passed into the interior of the receiving groove 201 through the connecting hole 206, and then enters the interior of the butterfly spring 203 through the liquid hole 204, so that the liquid can flow when the butterfly spring 203 is squeezed and when the butterfly spring 203 is restored, and then the butterfly spring 203 can be lubricated to reduce friction. At the same time, since the hole of the connecting hole 206 is small, the speed of the liquid flow can be limited, and then the butterfly spring 203 can be prevented from suddenly rebounding and impacting the interior of the outer column 1, thereby playing a shockproof role.

[0032] The driving mechanism 3 includes a fixed ring 301, which provides an installation position. The bottom of the fixed ring 301 is fixedly connected to the top of the outer column 1. The top of the fixed ring 301 is fixedly connected to the installation ring 302. The installation ring 302 provides an installation space. The inner side of the installation ring 302 is rotatably connected to the rotating ring 303. The outer side of the rotating ring 303 is fixedly connected to the inner side of the installation ring 302. The inner ring 305 is fixedly connected to the side away from the rotating ring 303. A plurality of blades 3 are fixedly connected. 06, the blade 306 can drive the inner ring 305 and the rotating ring 303 to rotate under the action of liquid flow, the rotating ring 303 is fixedly connected to the outer ring 304 on the side away from the inner ring 305, the outer ring 304 and the inner ring 305 can play a role in limiting, the outer sides of the mounting ring 302 are fixedly connected to the liquid pipe 307, the liquid pipe 307 can pass liquid, the bottom end of the outer column 1 is provided with a liquid tank 309, the liquid tank 309 is slidably connected to the inside of the movable plug 308, the mounting ring 302 is fixedly connected to the outer ring 305, the outer ring 304 and the inner ring 305 can play a role in limiting, the outer sides of the mounting ring 302 are fixedly connected to the liquid pipe 307, the liquid pipe 307 can pass liquid, the bottom end of the outer column 1 is provided with a liquid tank 309, the inner side of the liquid tank 309 is slidably connected to the movable plug 308, The interior of the liquid tank 309 is also filled with liquid and is divided into two layers with the movable plug 308 as the boundary. The top of the movable plug 308 is fixedly connected to the bottom of the movable column 202. When the movable plug 308 moves downward, the liquid in the space below the movable plug 308 in the liquid tank 309 will enter the interior of one of the liquid pipes 307 through one of the one-way liquid passing mechanisms 4, and then the liquid can flow inside the mounting ring 302, thereby driving the blade 306 to rotate. After the blade 306 rotates, it can drive the inner ring 305 to rotate. After the inner ring 305 rotates, it can drive the rotating ring 303 and the outer ring 304 to rotate, and then drive the cleaning mechanism 5 to rotate. The cleaning mechanism 5 is used to scrape off dust and impurities attached to the top column 207 to prevent the top column 207 from continuously moving up and down for a long time and entering the interior of the receiving groove 201, causing the friction between the butterfly spring piece 203 and the inner wall of the receiving groove 201 to increase, resulting in damage to the butterfly spring piece 203.

[0033] The one-way liquid flow mechanism 4 includes a mounting cylinder 401, which provides a mounting position. The two mounting cylinders 401 are fixedly connected to the bottom of the liquid flow pipe 307 on one side away from the outer column 1. The interior of the mounting cylinder 401 is slidably connected to a sealing round block 405, which serves as a limit. A plurality of holes 406 are provided inside the outer edge of the sealing round block 405, and the holes 406 can pass liquid. The middle part of the sealing round block 405 is fixedly connected to a stabilizing column 403, which can improve the stability of the movement of the sealing round block 405. The outer sleeve of the stabilizing column 403 is provided with a spring 404, and the outer sliding connection of the stabilizing column 403 is a fixing frame 402, and the outer periphery of the fixing frame 402 is fixedly connected to the interior of the mounting cylinder 401, stabilizing The side of the column 403 away from the sealing round block 405 is fixedly connected to the limit plate 407, the side of the mounting cylinder 401 away from the liquid pipe 307 is fixedly connected to the sealing seat 6, the two sealing seats 6 are fixedly connected to the two sides of the outer column 1 on the sides away from the liquid pipe 307, the interior of the mounting cylinder 401 is connected to the bottom of the liquid tank 309, one end of the spring 1 404 is fixedly connected to the side of the sealing round block 405 close to the limit plate 407, and the other end of the spring 1 404 is fixedly connected to the side of the fixing frame 402 close to the sealing round block 405. When the movable plug 308 moves downward, the liquid can be squeezed, so that the liquid pushes one of the sealing round blocks 405 to move in the direction away from the outer column 1. When the hole 40 on the sealing round block 405 is opened, the liquid is pushed out. When there is no installation cylinder 401 to block it, the spring 1 404 can be compressed, so that the liquid enters the interior of the installation cylinder 401 through the hole 406 and can be discharged through the liquid pipe 307. When the movable plug 308 moves upward, suction is generated in the space below the movable plug 308 in the liquid tank 309. At this time, one of the sealing round blocks 405 quickly moves toward the direction of the outer column 1 under the dual action of the spring 1 404 and the suction, and then the installation cylinder 401 can be used to block the hole 406. At this time, the liquid cannot enter the interior of the liquid tank 309 from one of the installation cylinders 401. When the movable plug 308 moves downward, the other sealing round block 405 will make the sealing block 405 open under the action of the liquid pressure. The sealing block 405 is tightly pressed against the inner side of the mounting tube 401, so that the inner side of the mounting tube 401 can be used to block the hole 406. When liquid enters the other liquid tube 307, the sealing block 405 is pushed toward the outer column 1 under the action of liquid pressure, so that the other sealing block 405 can move toward the outer column 1, and then the hole 406 on the other sealing block 405 is no longer blocked by the mounting tube 401, so that the liquid can enter the space below the movable plug 308 in the liquid tank 309 from the inside of the other mounting tube 401, thereby realizing unidirectional movement of the liquid in the space formed by the two liquid tubes 307 and the mounting ring 302.Then the rotating ring 303 can drive the cleaning mechanism 5 to rotate and then the dust on the top column 207 can be scraped off.

[0034] The cleaning mechanism 5 includes a mounting shell 501, which provides a mounting position. The exterior of the plurality of mounting shells 501 is fixedly connected to the interior of the rotating ring 303. A second spring 502 is provided inside the mounting shell 501. The interior of the mounting shell 501 is slidably connected to a limited circular block 503. The limited circular block 503 has a limiting function. A movable rod 504 is fixedly connected to the side of the limited circular block 503 away from the second spring 502. The movable rod 504 plays a connecting role. A cleaning brush 505 is fixedly connected to the side of the movable rod 504 away from the limiting circular block 503. The cleaning brush 505 can clean the top column 2. 07, one end of spring 202 is fixedly connected to the inner side of the mounting shell 501, and the other end of spring 202 is fixedly connected to the end of the limiting block 503 away from the movable rod 504. When the cleaning brush 505 is against the outer wall of the top column 207, the movable rod 504 and the limiting block 503 are compressing the spring 202. Therefore, the reaction force of spring 202 can be used to give the limiting block 503 and the movable rod 504 a force toward the top column 207, so that the cleaning brush 505 can be tightly pressed against the outside of the top column 207, thereby being able to scrape off the dust on the top column 207.

[0035] Working principle: after the top column 207 is squeezed, it can drive the movable column 202 to move downward, and can use the top column 207 to squeeze the butterfly spring piece 203, so that the butterfly spring piece 203 is deformed. Under the reaction force of the butterfly spring piece 203, the butterfly spring piece 203 has elasticity. When the butterfly spring piece 203 is deformed, the lubricating oil inside the butterfly spring piece 203 can flow out from the inside of the liquid hole 204. At the same time, the increase in the liquid inside the receiving groove 201 will enter the interior of the liquid groove 205 through the connecting hole 206, and enter the liquid filling groove 309 located in the upper part of the movable plug 308 through the liquid groove 205. At this time, due to the downward movement of the movable plug 308, the space in the upper half of the liquid filling groove 309 located in the movable plug 308 can be increased. At the same time, as the movable plug 308 moves, suction can be generated, so that the excess liquid in the liquid groove 205 will enter The liquid filling tank 309 is located in the upper half of the movable plug 308. When the butterfly spring piece 203 rebounds, it can drive the top column 207 to move upward, and then drive the movable column 202 and the movable plug 308 to move upward, so that the liquid in the upper half of the movable plug 308 can be squeezed into the interior of the liquid-passing tank 205, and the liquid in the liquid-passing tank 205 is passed into the interior of the receiving tank 201 through the connecting hole 206, and then enters the interior of the butterfly spring piece 203 through the liquid-passing hole 204, so that the liquid can flow when the butterfly spring piece 203 is squeezed and when the butterfly spring piece 203 recovers, and then the butterfly spring piece 203 can be lubricated to reduce friction. At the same time, since the hole of the connecting hole 206 is small, the speed of the liquid flow can be limited, and then the butterfly spring piece 203 can be prevented from suddenly rebounding and impacting the interior of the outer column 1, thereby playing a shockproof role.

[0036] When the movable plug 308 moves downward, the liquid in the space below the movable plug 308 in the liquid tank 309 will enter the interior of one of the liquid passages 307 through one of the one-way liquid passage mechanisms 4, and then the liquid will flow inside the mounting ring 302, thereby driving the blade 306 to rotate. After the blade 306 rotates, it can drive the inner ring 305 to rotate. After the inner ring 305 rotates, it can drive the rotating ring 303 and the outer ring 304 to rotate, and then drive the cleaning mechanism 5 to rotate, and use the cleaning mechanism 5 to scrape off the dust and impurities attached to the top column 207, so as to prevent the top column 207 from continuously moving up and down for a long time from entering the interior of the receiving groove 201, causing the friction between the butterfly spring piece 203 and the inner wall of the receiving groove 201 to increase, resulting in damage to the butterfly spring piece 203;

[0037] When the movable plug 308 moves downward, it can squeeze the liquid, so that the liquid pushes one of the sealing round blocks 405 to move in the direction away from the outer column 1. When the hole 406 on the sealing round block 405 is not blocked by the installation cylinder 401, the spring 1 404 can be compressed, so that the liquid enters the interior of the installation cylinder 401 through the hole 406 and can be discharged through the liquid pipe 307. When the movable plug 308 moves upward, the space below the movable plug 308 in the liquid tank 309 generates suction. At this time, one of the sealing round blocks 405 quickly moves toward the direction of the outer column 1 under the dual action of the spring 1 404 and the suction, and then the hole 406 can be blocked by the installation cylinder 401. At this time, the liquid cannot enter the interior of the liquid tank 309 from one of the installation cylinders 401, and when the movable plug 308 moves downward, the other sealing round block 405 The sealing block 405 is pressed tightly against the inner side of the installation cylinder 401 by the action of the liquid pressure, so that the hole 406 can be blocked by the inner side of the installation cylinder 401. When the liquid enters the other liquid tube 307, the sealing block 405 is pushed toward the outer column 1 by the action of the liquid pressure, so that the other sealing block 405 can be moved toward the outer column 1, and then the hole 406 on the other sealing block 405 is no longer blocked by the installation cylinder 401, so that the liquid can enter the space below the movable plug 308 in the liquid tank 309 from the inside of the other installation cylinder 401, thereby realizing the unidirectional movement of the liquid in the space formed by the two liquid tubes 307 and the installation ring 302, and then the rotating ring 303 can drive the cleaning mechanism 5 to rotate, so as to scrape off the dust on the top column 207.

[0038] When the cleaning brush 505 is pressed against the outer wall of the top column 207, the movable rod 504 and the limiting block 503 are compressing the spring 2 502. Therefore, the reaction force of the spring 2 502 can be used to give the limiting block 503 and the movable rod 504 a force toward the top column 207, thereby enabling the cleaning brush 505 to be tightly pressed against the outside of the top column 207, thereby scraping off the dust on the top column 207.
