Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curtain wall cleaning, in particular to a photovoltaic self-driven high-altitude curtain wall cleaning robot. BACKGROUND

[0002] At present, building curtain walls have been rapidly developed in China for 20 years due to their advantages such as beauty, energy saving, easy maintenance, etc. At present, the construction area is about 10 million square meters per year. However, long-term exposure to the natural environment, the curtain wall surface is easy to accumulate carbon dioxide, carbon monoxide, sulfur dioxide, chloride and oil smoke and other pollutants. These pollutants combined with rain and moisture can form acidic or alkaline attack on the curtain wall. If not regularly cleaned and maintained, the pollutants will penetrate into the building surface and corrode the surface and structure of the curtain wall. Therefore, regular cleaning and maintenance of building curtain walls are very important.

[0003] A curtain wall cleaning robot is disclosed in Chinese patent No. CN110638384A. The robot includes a rack, a roller brush assembly, a walking wheel and a pressure adjusting assembly. The cylinder of the roller brush assembly is pivoted to the rack, and the center line of the cylinder is parallel to the center line of the walking wheel. The outer edge of the cleaning piece protrudes from the outer edge of the walking wheel, so that the cleaning piece and the walking wheel can abut against the curtain wall to be cleaned. The pressure adjusting assembly is used to adjust the pressure between the walking wheel and the curtain wall to be cleaned, aiming to alleviate the problem of curtain wall damage caused by excessive friction between the walking wheel and the curtain wall. However, the above-mentioned device still has obvious defects in actual application. The device lacks an adsorption positioning structure for glass curtain walls. During cleaning, when the cleaning brush contacts the curtain wall surface, it can only rely on the rolling of the walking wheel on the glass curtain wall, and the cleaning brush plate cannot be stably attached to the outer surface of the curtain wall. Since the curtain wall is usually at a high position, the wind force is large, and the device is easily affected by strong wind during cleaning and shakes, which causes the cleaning brush to not always stably contact the glass curtain wall, thereby affecting the cleaning effect. This instability caused by the lack of stable adsorption structure makes the device have obvious deficiencies in cleaning operation, and it is difficult to meet the needs of efficient and thorough cleaning of the curtain wall. Therefore, it is necessary to improve the existing technology. SUMMARY

[0018] The following is combined with Figure 1-8This application is described in further detail.

[0019] The present application discloses a photovoltaic self-propelled high-altitude curtain wall cleaning robot. Figure 1-8 As shown, it includes a robot body 1, a power supply battery 2 is fixedly installed on the upper end of the back of the robot body 1, a cleaning mechanism 3 is fixedly installed in the middle of the back of the robot body 1, a cleaning liquid spraying mechanism 4 is fixedly installed in the middle of the front of the robot body 1, and a moving mechanism 5 is fixedly installed at the four corners of the robot body 1; The moving mechanism 5 includes a mounting plate 51, which is fixedly mounted on the upper and lower ends of both sides of the robot body 1. A first motor 52 is fixedly mounted on the middle part of the outer side of the mounting plate 51, and a connecting shaft 53 is fixedly mounted on the output end of the first motor 52. A moving wheel 54 is fixedly mounted on the outer end of the connecting shaft 53. The outer surface of the moving wheel 54 is fixedly mounted with elastic adsorption modules 56 arranged in a ring at equal intervals. During the application of this device, when the photovoltaic self-driven high-altitude curtain wall cleaning robot is working, the power supply battery 2 provides power support for each mechanism. After starting the equipment, the first motor 52 of the moving mechanism 5 drives the moving wheel 54 to rotate through the connecting shaft 53, and the elastic adsorption module 56 on the outer surface of the moving wheel 54 operates accordingly. The electric vacuum suction cup 564 generates negative pressure to adsorb on the curtain wall surface, providing a stable attachment basis for the equipment. During the rotation of the moving wheel 54, the elastic adsorption module 56 moves synchronously with it, and multiple electric vacuum suction cups 564 alternately adsorb and release in sequence. Combined with the automatic adjustment of the telescopic spring 562 and the reinforcing spring 566, it can adapt to the flatness changes of the curtain wall surface, ensuring that the equipment always fits tightly to the curtain wall, and can remain stable even in high-altitude strong wind environments to avoid shaking and offset. This design solves the cleaning instability problem caused by the lack of a stable adsorption structure in traditional equipment. At the same time, the cleaning mechanism 3 cleans the curtain wall surface under electric drive, and the cleaning liquid spraying mechanism 4 simultaneously provides cleaning liquid to assist in cleaning. The various mechanisms work together to improve cleaning efficiency and effectiveness. The rotation of the moving wheel 54 drives the entire robot body 1 to move along the curtain wall surface to achieve large-scale cleaning coverage. The flexible operation of the elastic adsorption module 56 not only ensures the smoothness of movement, but also avoids hard damage to the curtain wall surface.

[0020] Please refer to Figures 1-4The cleaning liquid spraying mechanism 4 includes a water tank 41, which is fixedly installed in the middle of the front of the robot body 1. A photovoltaic panel 8 is fixedly installed on the front of the water tank 41. A water pump 42 is fixedly installed in the middle of the upper end of the front of the water tank 41. The input end of the water pump 42 is connected to the interior of the water tank 41. A connecting pipe 43 is fixedly installed on the output end of the water pump 42. A horizontal pipe 44 is fixedly installed on the top of the connecting pipe 43. Cleaning liquid nozzles 45 are fixedly installed on the back of the horizontal pipe 44 in a linear arrangement at equal intervals. A cleaning liquid adding pipe 46 is fixedly installed at one end of the top of the water tank 41. The top of the liquid adding pipe 46 is threadedly connected with a sealing cover 47. During the use of this device, when the cleaning liquid spraying mechanism 4 is working, the cleaning liquid stored in the water tank 41 is extracted by the water pump 42, and is transported to the horizontal pipe 44 through the connecting pipe 43. Then, the cleaning liquid nozzle 45 on the back of the horizontal pipe 44 is evenly sprayed on the curtain wall surface, providing a wet environment for the subsequent cleaning of the brush plate 354, making it easier to remove stains on the curtain wall surface, especially those stubborn stains that are tightly attached. They can become loose under the infiltration of the cleaning liquid, thereby improving the overall cleaning effect. When the cleaning liquid in the water tank 41 is When the amount of cleaning liquid is insufficient, it can be replenished through the cleaning liquid adding pipe 46. After the addition is completed, the sealing cap 47 is threadedly connected to the top of the adding pipe, which can effectively prevent the cleaning liquid from leaking due to shaking during the movement or operation of the equipment, avoiding waste and secondary pollution of the curtain wall. At the same time, it can also keep the inside of the water tank 41 clean, ensure that the cleaning liquid is not contaminated by external impurities, and ensure that the sprayed cleaning liquid is always clean, without affecting the cleaning quality of the curtain wall. This whole set of spraying processes is coherent and efficient, and cooperates well with the cleaning mechanism 3, which can further improve the overall cleaning effect of the device. During the use of this device, the photovoltaic panel 8 outside the water tank 41 can efficiently absorb solar energy under light conditions and convert it into electrical energy through the internal conversion device. This electrical energy can be directly used to power various devices or stored in the power supply battery 2 for subsequent use. This design allows the device to be operated at high altitude without relying entirely on the initial power. It can supplement power through continuous light energy conversion, significantly reducing the operation interruption caused by insufficient power, effectively improving the continuous working ability and endurance of the device, and is particularly suitable for long-term cleaning operations on large-area curtain walls.

[0021] Please refer to Figures 1-6The cleaning mechanism 3 includes a guide rail 31, which is fixedly installed on the inner middle part of the robot body 1. A second motor 32 is fixedly installed on one end of the guide rail 31, and a screw rod 33 is fixedly installed on the output end of the second motor 32. The screw rod 33 is rotatably connected to the inside of the guide rail 31. The outer surface of the screw rod 33 is threadedly connected to a slider 34. The slider 34 is slidably connected to the inside of the guide rail 31. Rotating cleaning components 35 are installed on both sides of the guide rail 31. The rotating cleaning components 35 include side frames 351 and a base plate 352. The side frames 351 are fixedly installed on both sides of the guide rail 31. The outer side of the frame 351 is fixedly installed with a rack 353, and the base plate 352 is fixedly installed on the back of the slider 34. The two ends of the back of the base plate 352 are rotatably connected to the cleaning brush plate 354, and the two ends of the front of the base plate 352 are rotatably connected to the gear 355. The gear 355 and the rack 353 are meshed and connected. The middle part of the front of the cleaning brush plate 354 is fixedly connected to the back of the gear 355. The side shape of the slider 34 is convex, and the cross-section shape of the internal cavity of the guide rail 31 is also convex. The outer surface of the slider 34 is fixedly connected with a wear-resistant gasket. The outer corners are all set to be arc-shaped. When the cleaning mechanism 3 is working, the second motor 32 starts to drive the screw rod 33 to rotate inside the guide rail 31. The rotation of the screw rod 33 causes the slider 34 threadedly connected thereto to slide along the guide rail 31. The convex design on the side of the slider 34 is adapted to the convex structure of the internal cavity of the guide rail 31 to ensure that the sliding process is stable and without deviation. The wear-resistant gasket on the outer surface reduces the friction loss between the slider 34 and the guide rail 31, thereby extending the service life of the components. When the slider 34 moves, the base plate 352 moves synchronously with it, and the cleaning brush plate on the back of the base plate 352 354 then wipes the surface of the curtain wall, and at the same time, the gear 355 on the front of the base plate 352 engages with the rack 353 on the outside of the side frame 351. The gear 355 rotates under the action of the rack 353, thereby driving the cleaning brush plate 354 to rotate, forming a double cleaning action combining reciprocating movement and rotary wiping, which greatly enhances the cleaning force and can more thoroughly remove stains on the surface of the curtain wall. The arc-shaped edge design on the outside of the robot body 1 can reduce collision with the curtain wall during the movement of the equipment, avoid damage to the curtain wall, and ensure the safety of the cleaning operation.

[0022] Please refer to Figures 1-4 and Figure 7-Figure 8A conductive slip ring 55 is provided on the output shaft of the first motor 52, and the power supply battery 2 is electrically connected to each elastic adsorption module 56 on the outer surface of the moving wheel 54 through the conductive slip ring 55. A hanger 6 is fixedly installed on the top of the robot body 1, and a hanging rope 7 is fixedly installed on both ends of the top of the hanger 6. The elastic adsorption module 56 includes a fixed seat 561, and the fixed seats 561 are arranged in a ring shape with equal intervals and fixedly installed on the outer surface of the moving wheel 54. A telescopic spring 562 is fixedly installed on the outer side of the fixed seat 561, and a connecting plate 563 is fixedly installed on the outer end of the telescopic spring 562. Both ends of the connecting plate 563 are fixedly installed with an electric vacuum suction cup. 564, the elastic adsorption module 56 also includes a fixing ring 565, which is fixedly installed at the middle of the two ends of the hub of the moving wheel 54. The outer surface of the fixing ring 565 is evenly spaced and arranged in a ring shape with a reinforcing spring 566 fixed thereon. The outer end of the reinforcing spring 566 is fixedly connected to the inner end of the electric vacuum suction cup 564. During the application of this device, when working, the robot is suspended to the curtain wall working position with the help of the hanging rope 7 on the top of the hanger 6. The current released by the power supply battery 2 is continuously transmitted to the elastic adsorption module 56 on the outer surface of the moving wheel 54 through the conductive slip ring 55 on the output shaft of the first motor 52. After starting, the first motor 52 drives the moving wheel 54 to rotate, and the elastic adsorption module 56 moves synchronously with it. The telescopic spring 562 on the outside of the fixing seat 561 and the reinforcing spring 566 on the outside of the fixing ring 565 work together to push the electric vacuum suction cups 564 at both ends of the connecting plate 563 to approach and contact the curtain wall surface. After the suction cups are energized, negative pressure is formed to complete the adsorption. During the rotation of the moving wheel 54, the ring-shaped elastic adsorption modules 56 alternately perform adsorption and release actions in sequence. When one group of suction cups is about to leave the curtain wall, the adjacent group of suction cups has completed adsorption, ensuring uninterrupted adsorption force. The telescopic spring 562 and the reinforcing spring 566 can automatically adjust the suction cups according to the undulations of the curtain wall surface. The telescopic adjustment allows the electric vacuum suction cup 564 to always maintain a close fit with the curtain wall, and it can maintain stable attachment even under the influence of high-altitude wind, avoiding the shaking caused by unstable adsorption of traditional equipment. During use, its conductive slip ring 55 maintains circuit connectivity when the output shaft of the first motor 52 rotates, ensuring that the power supply of the elastic adsorption module 56 is uninterrupted, allowing the adsorption function to continue to be stable. The dual elastic support of the telescopic spring 562 and the reinforcing spring 566 not only cushions the impact force when the moving wheel 54 rotates, but also reduces the hard contact between the suction cup and the curtain wall, reducing the risk of damage to the curtain wall surface, while ensuring the smoothness of the movement process.

[0023] The implementation principle of a photovoltaic self-driven high-altitude curtain wall cleaning robot in the embodiment of the present application is as follows: during the application of the equipment, when in use, first connect the lifting rope 7 to the lifting equipment on the top of the building, and with the help of the traction of the lifting equipment, the robot is stably suspended at a suitable position on the curtain wall through the hanger 6. The outer edges and corners of the base frame are designed in an arc shape, which can reduce direct collision with the curtain wall during the movement and operation of the equipment and reduce the risk of damage to the curtain wall surface. The power supply battery 2 provides continuous power support for the operation of the entire equipment. The conductive slip ring 55 on the output shaft of the first motor 52 ensures that the power can be stably transmitted to the various elastic adsorption modules 56 on the outer surface of the moving wheel 54 to ensure the normal start-up of the adsorption function. After starting the equipment, the first motor 52 of the moving mechanism 5 starts to run, and drives the moving wheel 54 to rotate through the connecting shaft 53. At this time, the electric vacuum suction cup 564 of the elastic adsorption module 56 is energized to generate negative pressure, which is firmly adsorbed on the curtain wall surface, providing a reliable initial fixing force for the equipment. As the moving wheel 54 rotates, the elastic adsorption module The group 56 follows the movement synchronously, and the telescopic spring 562 on the outside of the fixing seat 561 and the reinforcing spring 566 outside the fixing ring 565 cooperate with each other to automatically adjust the telescopic and retractable positions according to the flatness of the curtain wall surface. When one group of electric vacuum suction cups 564 is about to leave the curtain wall surface during movement, the other group of electric vacuum suction cups 564 just contacts the outer surface of the curtain wall and starts adsorption. The design of the telescopic spring 562 and the reinforcing spring 566 can be flexibly extended to ensure that the multiple electric vacuum suction cups 564 on the outer surface of the circular moving wheel 54 can be adsorbed synchronously. At this time, the previous electric vacuum suction cups 564 can be closed. This alternating adsorption and release method, combined with the flexible extension adsorption function given by the telescopic spring 562 and the reinforcing spring 566, ensures that the electric vacuum suction cups 564 can always be in close contact with the curtain wall, effectively avoiding the unstable adsorption force, ensuring the stable movement of the equipment on the curtain wall surface, and replacing the hard contact mode of the traditional walking wheel, solving the problem of damage to the curtain wall caused by unstable friction. During the cleaning process, the water pump 42 of the cleaning liquid spraying mechanism 4 can be started, and the cleaning liquid in the water tank 41 is transported to each cleaning liquid spray head 45 through the connecting pipe 43 and the cross pipe 44 under the action of the water pump 42, and finally sprayed uniformly on the surface of the curtain wall, creating a humid environment for subsequent cleaning operations, which is more conducive to removing stubborn stains that adhere closely. When the cleaning liquid in the water tank 41 is insufficient, it can be supplemented through the cleaning liquid adding pipe 46. After the addition is completed, the sealing cap 47 is tightened to effectively prevent waste and pollution caused by cleaning liquid leakage. Subsequently, the second motor 32 of the cleaning mechanism 3 is started to drive the rotation of the screw rod 33 inside the guide rail 31. The rotation of the screw rod 33 drives the sliding block 34 connected with it by threads to slide smoothly along the guide rail 31. The convex design on the side surface of the sliding block 34 matches the shape of the internal cavity of the guide rail 31, ensuring the stability of the sliding process. The wear-resistant pad on the outer surface of the sliding block 34 reduces the direct friction between the sliding block 34 and the guide rail 31, reducing the wear degree of the components and prolonging the service life of the equipment. While the sliding block 34 moves, the cleaning brush plate 354 on the back of the base plate 352 moves synchronously. The gear 355 on the front of the base plate 352 is engaged with the rack 353 on the outside of the side frame 351. The gear 355 rotates under the action of the rack 353, thereby driving the cleaning brush plate 354 to rotate. By starting the forward and reverse rotation of the second motor 32, reciprocating wiping and cleaning can be formed. The cleaning brush plate 354 can be selected according to the cleaning requirements. The reciprocating wiping and rotating cleaning combination greatly improves the cleaning effect on the surface of the curtain wall, ensuring that the stains can be completely removed. During the application of the device, when the work is completed, the power of each mechanism of the device is turned off, the electric vacuum chuck 564 stops working, the negative pressure state is released, and the adsorption force disappears. At this time, the hoisting rope 7 is pulled through the hoisting equipment on the top of the building to safely recover the robot to the ground. During the entire cleaning process, the negative pressure generated by the electric vacuum chuck 564 of the elastic adsorption module 56, in combination with the adjustment of the extension spring 562 and the reinforcing spring 566, successfully solves the problem that the cleaning brush cannot be stably attached to the curtain wall due to the lack of adsorption structure in the background technology. Even in a high-altitude strong wind environment, the device can be firmly fixed to the surface of the curtain wall, ensuring that the cleaning brush plate 354 always maintains close contact with the curtain wall. The moving wheel 54 moves with the help of the elastic adsorption module 56, avoiding the hard contact between the traditional walking wheel and the curtain wall, effectively preventing damage to the curtain wall caused by unstable friction. The dual cleaning method of the cleaning mechanism 3 and the cooperation of the cleaning liquid spraying solve the problem of incomplete cleaning of traditional equipment. The reasonable design of the sliding block 34 and the guide rail 31 and the orderly layout of each mechanism further enhance the practicality and durability of the device, making the entire cleaning operation process convenient and efficient, meeting the actual needs of high-altitude curtain wall cleaning.

[0024] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
