Description

Technical Field

[0001] The invention belongs to the technical field of curtain wall cleaning, in particular to a cleaning robot for building curtain walls. Background Art

[0002] With the development of the times, glass is widely used in the construction industry as a light-transmitting and wind-blocking material. Along with it is the rise of the building glass curtain wall cleaning industry. An existing cleaning robot adopts the adsorption principle, firmly adsorbs on the glass curtain wall through a suction cup or a magnetic device, and then uses a walking device to move on the curtain wall surface, while carrying a cleaning system to clean the curtain wall.

[0003] A patent application with publication number CN116158685A discloses an automatic cleaning device for building glass curtain walls, including a glass-wiping robot. A support plate is provided inside the glass-wiping robot, a cleaning component is placed on the upper part of the support plate, and the cleaning component is used for spraying water for cleaning. The T-block is driven up and down by an incomplete gear, and is rotatably connected by a fixed connecting block and a matching connecting block, so that the cleaning plate slides on the surface of the glass curtain wall and can wipe the surface stains of the glass curtain wall. The compression block is pushed by the cam block, and the stirred cleaning agent will be sucked into the compression chamber, and squeezed through the flushing spray box to be quickly sprayed onto the surface of the glass curtain wall, so that it is quickly adsorbed into the stains, facilitating subsequent wiping work.

[0004] The above scheme still has some problems in practical application. When the device is used for cleaning, in order to ensure that it will not fall due to failure or operating error during operation, a rope sufficient to bear the weight of the device needs to be hung from the roof, and the rope needs to pass through the device. However, since some glass curtain walls are only concave but not convex glass surfaces, and the device moves on the glass through the suction cups on the crawler, when passing through the concave surface, due to the limitation of the rope, the crawler cannot fit with the concave glass, making it very easy for the device to not fit with the glass. If the device is set to be tiltable, the sprayed cleaning liquid cannot be accurately sprayed on the glass curtain wall to be cleaned.

DETAILED DESCRIPTION

[0021] 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.

[0023] Specifically, the cleaning robot for a building curtain wall of the scheme is mainly used for cleaning glass curtain walls. When in use, firstly, a set of safety ropes 5 sufficient to bear the weight of the cleaning robot needs to be hung from the roof of the building, and the safety ropes 5 need to pass through the shell 1, so that the shell 1 slides along the surface of the safety ropes 5, and then the surface of the shell 1 is made parallel to the glass curtain wall, the shell 1 is placed at the starting position of the glass curtain wall, and it is ensured that the suction cup 22 on the surface of the conveying roller 21 is stably adsorbed on the glass surface, at this time, the conveying roller 21 is started for conveying, and the cleaning robot will move along the safety ropes 5 to the glass curtain wall. At this time, the glass curtain wall cleaning agent will be discharged from the water tank 405. Since the bottom surface of the shell 1 is perpendicular to the ground at this time, the glass curtain wall cleaning agent will also move downward with gravity and finally fall on the surface of the extrusion plate 408. At this time, the extrusion plate 408 and the worm 404 are started, and the extrusion plate 408 will move upward, and finally the glass curtain wall cleaning agent will be squeezed into the inside of the worm 404. Since the worm 404 is still rotating at this time, the worm 404 will The glass curtain wall cleaning agent is squeezed into the interior of the cleaning frame 31, and due to the continuous rotation of the worm 404, the glass curtain wall cleaning agent will not flow back. When the glass curtain wall cleaning agent reaches a certain dosage, the glass curtain wall cleaning agent will flow out from the holes on the surface of the water supply pipe 33, and finally spray out from the surface of the nozzle 34 to the surface of the glass curtain wall. Then, the brush 37 can be started to clean the glass curtain wall, and when the cleaning robot moves to the concave glass, the adjustment spring 403 at this time will release the elastic force and push the brush 37 to contact with the concave surface of the glass curtain wall, and then the sliding tooth plate 403 is started. 14, the sliding tooth plate 414 will drive the conveying roller 21 to move in the moving direction of the brush 37, and move the same distance, so that the suction cup 22 on the surface of the conveying roller 21 is always attracted to the glass curtain wall. By setting the sliding tooth plate 414, when the cleaning robot moves to the concave glass, the cleaning robot can always remain perpendicular to the ground while maintaining a precise connection with the glass curtain wall, thereby not affecting the position of the safety rope 5, and the nozzle 34 and the brush 37 used to clean the glass curtain wall will also adaptively adjust the distance between them and the glass curtain wall, so as to better clean.

[0024] like Figures 1 to 8As shown, the cleaning structure 3 further includes: a moving circular frame 32, which is arranged at one end of the water supply pipe 33; a water storage frame 35, which is arranged inside the moving circular frame 32 and connected to the water supply pipe 33; the adjustment structure 4 further includes: a connecting arm 401, which is arranged at one end of the moving circular frame 32, and the other end of the connecting arm 401 slides inside the shell 1; a moving frame 415, which is arranged inside the shell 1, and the moving frame 415 is arranged at one end of the connecting arm 401; a sliding rod 419, which is arranged inside the shell 1 19 is arranged inside the shell 1; the sliding ring 418, the sliding ring 418 is slidably connected to the surface of the sliding rod 419; the abutment block 416, the abutment block 416 is connected to the sliding ring 418, and the moving frame 415 contacts the abutment block 416 during operation; the adjusting gear 420, the adjusting gear 420 is arranged at one end of the abutment block 416, and the adjusting gear 420 is engaged with the sliding tooth plate 414 during operation; the abutment roller 412, the abutment roller 412 is rotatably connected to the inside of the shell 1, and the adjusting gear 420 slides on the surface of the abutment roller 412.

[0025] Specifically, when cleaning the glass curtain wall, the glass curtain wall cleaning agent will enter the water storage frame 35 through the water supply pipe 33 and finally be sprayed out from the nozzle 34. When the cleaning robot moves to the concave glass, the movable circular frame 32 will be pushed to contact the concave surface of the glass curtain wall, and the movable circular frame 32 will drive the movable frame 415 to move through the connecting arm 401, and the movable frame 415 will contact the inclined surface of the abutment block 416, so that the abutment block 416 drives the adjusting gear 420 toward the abutment roller 412. The abutment roller 412 is provided with a small card strip on the surface of the abutment roller 412, and the small card strip is engaged with the inner wall of the adjusting gear 420. At this time, the abutment roller 412 is started to rotate, and the abutment roller 412 will drive the adjusting gear 420 to rotate. Since the adjusting gear 420 is meshed with the sliding tooth plate 414, the sliding tooth plate 414 will eventually move the conveying roller 21 in the moving direction of the brush 37 and move the same distance to achieve adjustment.

[0026] like Figure 8 As shown, a compression spring 417 is provided between the adjusting gear 420 and the abutting block 416 .

[0027] Specifically, when the abutment block 416 drives the adjusting gear 420 to connect with the abutment roller 412, since a small clip is provided on the surface of the abutment roller 412, when the adjusting gear 420 contacts the abutment roller 412, the adjusting gear 420 may not be directly connected with the abutment roller 412. By providing an extrusion spring 417, since the abutment roller 412 is continuously rotating, and the extrusion spring 417 at one end of the adjusting gear 420 will continue to apply pressure, when the abutment roller 412 rotates to a direction consistent with the adjusting gear 420, the extrusion spring 417 at this time will quickly push the adjusting gear 420 to connect with the abutment roller 412.

[0028] like Figures 1 to 9 As shown, a pressing spring 421 is provided at the lower end of the extrusion plate 408 , and an intermittent gear 409 is rotatably connected to one end of the housing 1 close to the extrusion plate 408 , and the intermittent gear 409 is meshed with the extrusion plate 408 .

[0029] Specifically, by setting the intermittent gear 409, when the glass curtain wall cleaning agent is transferred to the surface of the extrusion plate 408, the intermittent gear 409 is started to rotate. While rotating, the intermittent gear 409 will drive the extrusion plate 408 to move upward, thereby squeezing the glass curtain wall cleaning agent into the inside of the worm 404, and then the intermittent gear 409 will no longer mesh with the extrusion plate 408. At this time, the pressing spring 421 will release the elastic force and pull the extrusion plate 408 back to its original position. After the intermittent gear 409 rotates one circle, it will mesh with the extrusion plate 408 again, thereby ensuring the continuous transfer of the glass curtain wall cleaning agent.

[0030] like Figures 1 to 10 As shown, a connecting chain 411 is sleeved on the surface of the intermittent gear 409 , and the other end of the connecting chain 411 is connected to the abutting roller 412 .

[0031] Specifically, by providing the connecting chain 411, when the intermittent gear 409 rotates, the abutting roller 412 will be driven to rotate through the connecting chain 411, so that the two rotate at the same time.

[0032] Embodiment 2 like Figure 6 As shown, in contrast to Example 1, another implementation of the present invention is that a sealing strip 413 is provided on the side of the extrusion plate 408 , and the sealing strip 413 is in contact with the inner wall of the housing 1 .

[0033] Specifically, by providing the sealing strip 413 , it can be ensured that when the squeezing plate 408 transfers the glass curtain wall cleaning agent, no glass curtain wall cleaning agent will flow out from the side of the squeezing plate 408 .

[0034] like Figures 1 to 5 As shown, a ball plug 407 is provided at one end of the housing 1 near the water tank 405 .

[0035] Specifically, by setting the ball plug 407, when the water tank 405 transfers the glass curtain wall cleaning agent to the surface of the extrusion plate 408, as the liquid level continues to rise, the ball plug 407 will block the channel between the water tank 405 and the extrusion plate 408, thereby preventing the glass curtain wall cleaning agent from flowing back due to excessive content of the glass curtain wall cleaning agent.

[0036] like Figures 1 to 5 As shown, a rotating rod 406 is provided at one end of the housing 1 close to the ball plunger 407 , and the ball plunger 407 is rotatably connected to the arc surface of the rotating rod 406 .

[0037] Specifically, by providing the rotating rod 406 , as the liquid level continues to rise, the ball plug 407 will rotate along the arc surface of the rotating rod 406 and eventually block the passage between the water tank 405 and the extrusion plate 408 .

[0038] like Figures 1 to 3 As shown, a heating tube 402 is provided inside the housing 1 .

[0039] Specifically, by providing the heating tube 402, when the cleaning robot moves, the heating tube 402 located inside the shell 1 is started, and the heating tube 402 will heat the part just cleaned, thereby accelerating the drying of the glass.

[0040] like Figures 1 to 12 As shown, a rotating disk 36 is rotatably connected inside the movable circular frame 32 , and a water storage frame 35 is provided at one end of the rotating disk 36 , and a brush 37 is provided at the other end of the rotating disk 36 .

[0041] Specifically, when cleaning the glass curtain wall, the turntable 36 is started to rotate. Since the water storage frame 35 and the brush 37 are both arranged on the surface of the turntable 36, when the glass curtain wall cleaning agent is sprayed out from the nozzle 34, the turntable 36 rotates, and the brush 37 will quickly clean and wipe the glass curtain wall, thereby achieving a better cleaning effect.

[0042] Working principle: When in use, firstly, a set of safety ropes 5 sufficient to bear the weight of the cleaning robot needs to be hung from the roof of the building, and the safety ropes 5 need to pass through the shell 1, so that the shell 1 slides along the surface of the safety ropes 5, and then the surface of the shell 1 is made parallel to the glass curtain wall, the shell 1 is placed at the starting position of the glass curtain wall, and it is ensured that the suction cup 22 on the surface of the conveying roller 21 is stably adsorbed on the glass surface, and then the conveying roller 21 is started for conveying, and the cleaning robot will move upward along the safety ropes 5, and at the same time, the water tank 405 is started, and the glass curtain wall cleaning agent is placed inside the water tank 405, and the glass curtain wall cleaning agent will be discharged from the water tank 405 at this time, because the bottom surface of the shell 1 at this time is The cleaning agent for the glass curtain wall will be vertical to the ground, so the glass curtain wall cleaning agent will also move downward with gravity, and finally fall on the surface of the extrusion plate 408, starting the rotation of the intermittent gear 409. The intermittent gear 409 will drive the extrusion plate 408 to move upward while rotating, and finally squeeze the glass curtain wall cleaning agent into the inside of the worm 404. Since the worm 404 is still rotating at this time, the worm 404 will squeeze the glass curtain wall cleaning agent into the inside of the cleaning frame 31, and since the worm 404 keeps rotating, the glass curtain wall cleaning agent will not flow back, and then the intermittent gear 409 will no longer mesh with the extrusion plate 408. At this time, the pressing spring 421 will release its elastic force to pull the extrusion plate 408 back to its original position. After the gear 409 rotates one circle, it will mesh with the extrusion plate 408 again to ensure the continuous transfer of the glass curtain wall cleaning agent. When the glass curtain wall cleaning agent reaches a certain dosage, the glass curtain wall cleaning agent will enter the water storage frame 35 through the water supply pipe 33 and finally be sprayed out from the nozzle 34. When the cleaning robot moves to the concave glass, the adjustment spring 403 will release the elastic force at this time and push the moving circular frame 32 to contact the concave surface of the glass curtain wall, and the moving circular frame 32 will drive the moving frame 415 to move through the connecting arm 401, and the moving frame 415 will contact the inclined surface of the abutment block 416, so that the abutment block 416 drives the adjustment gear 420 toward the abutment roller 412 , and finally the inner wall of the adjusting gear 420 contacts the surface of the abutting roller 412. Since a small card strip is provided on the surface of the abutting roller 412, and the small card strip is engaged with the inner wall of the adjusting gear 420, and since a connecting chain 411 is provided between the intermittent gear 409 and the abutting roller 412, the abutting roller 412 is rotating at this time, and the abutting roller 412 will also drive the adjusting gear 420 to rotate. Since the adjusting gear 420 is meshed with the sliding tooth plate 414, the sliding tooth plate 414 will eventually move the conveying roller 21 in the moving direction of the brush 37, and move the same distance, so that the suction cup 22 on the surface of the conveying roller 21 is always attracted to the glass curtain wall.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
