As the device is continuously used, these impurities will block the water circulation pipes and affect the normal use of the device. Summary of the invention

[0036] The reciprocating spray structure 2 includes a fixed track 201, a telescopic cylinder 202, a sliding bracket 203, a water tank 204 and a spray pipe 205. The fixed track 201 is fixedly connected to the maintenance frame assembly 1, the telescopic cylinder 202 is fixedly connected to the maintenance frame assembly 1, the sliding bracket 203 is slidably connected in the fixed track 201, the sliding bracket 203 is fixedly connected to the output end of the telescopic cylinder 202, the water tank 204 is fixedly connected to the sliding bracket 203, the spray pipe 205 is fixedly connected to the sliding bracket 203, and the spray pipe 205 passes through and is fixedly connected to the water tank 204.

[0037] The maintenance frame assembly 1 includes a placement box 101, a partition plate 102, a recovery pipe 103, a delivery pipe 104 and a water pump 105. The partition plate 102 is fixedly connected to the inner surface of the placement box 101, one end of the recovery pipe 103 passes through and is fixedly connected to the placement box 101, one end of the delivery pipe 104 passes through and is fixedly connected to the recovery pipe 103, the other end of the delivery pipe 104 passes through and is fixedly connected to the water tank 204, and the water pump 105 is fixedly connected to the outer surface of the placement box 101.

[0038] The driven rack 408 is meshedly connected to the docking gear 418, the driving rack 415 is meshedly connected to the docking gear 418, and the driving motor 402 is a dual-rotor synchronous motor.

[0039] The fixing plate 401 is fixedly connected to the filter frame 301 , the reciprocating lifting track 302 is symmetrically arranged on the filter frame 301 , the driving pulley 311 is arranged inside the filter frame 301 , and the active pulley 306 is arranged outside the filter frame 301 .

[0040] The intermediate bevel gear 419 is meshedly connected to the driven bevel gear 314 , the support plate 420 is fixedly connected to the filter frame 301 , and the intermediate bevel gear 419 is rotatably connected to the support plate 420 .

[0041] There are two groups of sector gears 309 . The sector gears 309 rotate in the same direction. Both groups of sector gears 309 are meshed with the double-sided rack plate 304 .

[0042] During specific use, the building structure members that need to be sprayed and maintained (such as concrete slabs, etc.) are placed in a single space separated by the partition plate 102 inside the placement box 101, and the one-way valve arranged between the spray pipe 205 and the water tank 204 is opened. The water inside the water tank 204 is sprayed onto the building structure members inside the maintenance frame assembly 1 through the spray pipe 205, and then the telescopic cylinder 202 is started. After the telescopic cylinder 202 is started, it drives the sliding bracket 203 to move back and forth along the fixed track 201 to spray all the building structure members placed inside the placement box 101.

[0043] Start the water pump 105. During the spraying process, the water will eventually gather on the bottom surface of the placement box 101 after being sprayed onto the building structure. After the water pump 105 is started, the water inside the placement box 101 is pumped into the inside of the delivery pipe 104 through the recovery pipe 103, and finally the water inside the delivery pipe 104 enters the inside of the water tank 204, thereby realizing circulating spraying. In the process of circulating spraying maintenance of the building structure, some impurities on the outer surface of these building structure may fall off under the action of the water flow. These fallen impurities move with the water flow and are filtered on the outer surface of the filter frame 301 under the action of the filter frame 301, so that these impurities cannot enter the inside of the recovery pipe 103 and the delivery pipe 104, thereby avoiding blockage of the recovery pipe 103 and the delivery pipe 104.

[0044] With the continuous use of the device, the amount of impurities accumulated on the outer surface of the filter frame 301 increases continuously, and the amount of water passing through the filter frame 301 decreases. At this time, the rotation speed of the turbofan 409 decreases, thereby reducing the rotation speed of the fixed ring 410. As the rotation speed of the fixed ring 410 decreases, the centrifugal force exerted on the extension block 411 provided on the fixed ring 410 decreases, and the extension block 411 contracts inwardly under the action of the return spring 412. As the return spring 412 contracts inwardly, the transmission bracket 414 synchronously moves inwardly under the action of the telescopic spring 416, and the transmission bracket 414 drives the driving rack 415 to move synchronously. The displacement of the driving rack 415 drives the The connecting gear 418 rotates, and the rotation of the docking gear 418 drives the driven rack 408 to move in the opposite direction of the transmission bracket 414. With the displacement of the driven rack 408, the driven rack 408 drives the control bracket 407 to move synchronously. The displacement of the control bracket 407 drives the key shaft 405 to move along the key slot 404, so that the driving bevel gear 406 is meshed and connected with the intermediate bevel gear 419. The driving motor 402 always keeps running, and the driving motor 402 drives the output shaft 403 to rotate. The output shaft 403 drives the key shaft 405 to rotate synchronously through the key slot 404. The key shaft 405 drives the driving bevel gear 406 to rotate, and the driving bevel gear 406 drives The intermediate bevel gear 419 rotates, and the intermediate bevel gear 419 rotates to drive the driven bevel gear 314 to rotate. The driven bevel gear 314 drives the driven pulley 312 to rotate. The driven pulley 312 drives the driving pulley 311 to rotate synchronously through the connecting belt 313. The driving pulley 311 rotates to drive the rotating shaft 305 to rotate synchronously. The rotating shaft 305 drives the driving pulley 306 to rotate. The driving pulley 306 drives the driven pulley 307 to rotate synchronously through the transmission belt 310. At this time, the sector gear 309 rotates under the action of the rotating shaft 305 and the fixed shaft 308, and the double-sided rack plate 304 moves up and down under the action of the sector gear 309. As the filter frame 301 moves back and forth, the double-sided rack plate 304 drives the cleaning brush plate 303 to scrub the outer surface of the filter frame 301. As the cleaning brush plate 303 scrubs, the amount of impurities on the outer surface of the filter frame 301 decreases, the water flow rate increases, the speed of the turbofan 409 increases, and the centrifugal force exerted on the extension block 411 is greater than the supporting force provided by the reset spring 412. The extension block 411 expands outward. At this time, the transmission bracket 414 moves outward, and the control bracket 407 drives the key shaft 405 to move in the opposite direction of the transmission bracket 414. The driving bevel gear 406 is disengaged from the intermediate bevel gear 419 driven by the key shaft 405, and the reciprocating lifting track 302 loses the driving force and stops moving back and forth.

[0045] When the water flow rate sprayed by the spray pipe 205 continues to remain low, it can effectively remind the staff that the number of impurities inside the device is too large. At this time, the staff can stop using the device and clean the impurities inside it. The above is the overall workflow of the present invention. Just repeat this step next time you use it. The actual operation process is very simple and easy.
