[0032] The high-altitude curtain wall cleaning equipment proposed in the present invention is adsorbed on the high-altitude curtain wall by the wall-climbing chassis 100, and a main roller brush disc 212 and an auxiliary roller brush disc 213 are arranged on the scrubbing arm 211. The high-altitude curtain wall is cleaned by rotating the brushes 2124 on the main roller brush disc 212 and the auxiliary roller brush disc 213. During cleaning, the two auxiliary roller brush discs 213 swing relative to each other along the scrubbing arm 211, thereby further improving the cleaning efficiency. By arranging a pneumatic rod 300 between the wall-climbing chassis 100 and the scrubbing arm 211, when facing an uneven high-altitude curtain wall, the height of the scrubbing arm 211 can be adjusted so that the roller brush disc and the wall surface always maintain an optimal contact distance, thereby further improving the cleaning effect of the high-altitude curtain wall cleaning equipment. In addition, there is no need to manually climb to the high-altitude curtain wall to perform operations during the entire cleaning process, thereby improving safety. This high-altitude curtain wall cleaning equipment solves the problems of low efficiency and low safety in cleaning high-altitude curtain walls in traditional technologies.

[0033] One end of the scrubbing arm 211 is hingedly connected to the wall-climbing chassis 100, and the ends of the main roller brush disc 212 and the auxiliary roller brush disc 213 are both provided with brushes 2124. The scrubbing arm 211 is also provided with a pneumatic rod 300, one end of which is hingedly connected to the wall-climbing chassis 100, and the other end of which is hingedly connected to the scrubbing arm 211. Specifically, when uneven surfaces appear on the high-altitude curtain wall, the scrubbing arm 211 can adjust itself according to the height changes of the wall surface, so that the roller brush disc and the wall surface always maintain an optimal contact distance, and the pneumatic rod 300 can make the lifting and lowering movement of the scrubbing arm 211 more gentle, further improving the cleaning effect of the high-altitude curtain wall cleaning equipment.

[0034] The connecting member 2142 includes a crank 2142a, a first connecting rod 2142b and a second connecting rod 2142c, and a pivot shaft 2142d respectively connected to the first connecting rod 2142b and the second connecting rod 2142c. The first connecting rod 2142b and the second connecting rod 2142c are respectively hingedly connected to the two rocker rods 2141, and the pivot shaft 2142d is used to repeatedly pivot the two rocker rods 2141 to move. One end of the crank 2142a is connected to the turbine 2143, and the other end of the crank 2142a is connected to the pivot shaft 2142d.

[0035] Specifically, the worm motor 2144 drives the turbine 2143 to rotate, and the crank 2142a connected to the turbine 2143 repeatedly moves to drive the pivot shaft 2142d to move. The pivot shaft 2142d repeatedly pivots the two rocker rods 2141 connected to the second through the first connecting rod 2142b, and the two rocker rods 2141 drive the two auxiliary roller brush plates 213 to swing relative to each other along the scrubbing arm 211.

[0036] The wall-climbing chassis 100 includes a loading chassis 110, a vacuum pump 120 fixedly connected to the loading chassis 110, and two adsorption devices respectively fixed on both sides of the loading chassis 110, the adsorption device includes an adsorption track and a second drive device 150, the adsorption track includes a transmission chain 130 and a plurality of vacuum suction cups 140 fixed on the transmission chain 130, the second drive device 150 is connected to the transmission chain 130 to drive the transmission chain 130 to rotate, the vacuum pump 120 is respectively connected to two multi-gas distribution solenoid valves 170 through two first hoses 160, each of the vacuum suction cups 140 is respectively connected to the multi-gas distribution solenoid valve 170 through a second hose 180, and the cleaning device is fixed on the loading chassis 110.

[0037] Specifically, the second driving device 150 adopts a driving motor, which outputs power to drive the transmission chain 130 to rotate. The vacuum suction cup 140 fixed on the transmission chain 130 moves along with the rotation of the transmission chain 130, thereby realizing the overall movement of the robot wall-climbing chassis 100. When the vacuum pump 120 is working, the multi-air path distribution solenoid valve 170 reasonably distributes the vacuum air path to the required vacuum suction cup 140. The vacuum suction cup 140 is in a vacuum state, and the pressure is much lower than the external air pressure. Due to the effect of pressure, the vacuum suction cup 140 is adsorbed on the wall, thereby realizing the stable adsorption of the robot wall-climbing chassis 100 on the wall.

[0038] In a specific implementation, multiple second hoses 180 are connected to multiple vacuum suction cups 140 via an air slip ring (not shown). By setting an air slip ring (not shown) between the vacuum suction cup 180 and the multi-air path distribution solenoid valve 170, on the one hand, the air path signal is transmitted, and on the other hand, the second hose 180 is prevented from being entangled and knotted when directly connected to the multi-air path solenoid valve 170 for operation.

[0039] In a specific implementation, a plurality of compartments are provided on the cargo-carrying chassis 110 , and the water tank 202 , the first micro water pump 204 , and the second micro water pump 207 are placed in each compartment for easy management.

[0040] The cleaning liquid supply device 200 includes a nozzle 201, a water tank 202, a first water pipe 203, and a first micro water pump 204. The water tank 202 and the first micro water pump 204 are both fixed on the wall-climbing chassis 100. The water tank 202 contains cleaning liquid. The first water pipe 203 is respectively connected to the nozzle 201 and the water pipe. The nozzle 201 is arranged near the end of the brush 2124. Under the action of the first micro water pump 204, the cleaning liquid in the water tank 202 is sprayed out from the nozzle 201 through the first water pipe 203.

[0041] Specifically, the nozzle 201 adopts an atomizing nozzle, which can further improve the cleaning effect.

[0042] The cleaning liquid supply device 200 also includes a sewage filter device fixedly mounted on the wall climbing chassis 100, the sewage filter device includes a second water pipe 205, a sewage filter water tank 206, a second micro water pump 207, and a water storage assembly 208. The second water pipe 205 is connected to the water storage assembly 208 and the sewage filter water tank 206 respectively. The water storage assembly 208 is arranged near the end of the brush 2124. Under the action of the second micro water pump 207, the sewage in the water storage assembly 208 enters the sewage filter water tank 206 through the second water pipe 205, and enters the water tank 202 after being filtered in the sewage filter water tank 206. A scraper 400 is arranged on the cargo carrying chassis 110, and the water storage assembly 208 is arranged inside the scraper 400. The scraper 400 is used to scrape off the water droplets remaining on the surface of the curtain wall after the cleaning mechanism cleans it, and collect the water droplets and gather them in the water storage assembly 208. A spring pressing device 410 is provided between the scraper 400 and the wall-climbing chassis 100 .

[0043] Specifically, during cleaning, the scraper 400 scrapes and collects the sewage on the wall, collects it in the water storage component 208, and under the action of the second micro water pump 207, the sewage enters the sewage filter tank 206 for filtration. In specific implementation, the sewage filter box is provided with filter cotton and filter net, and the filter cotton and filter net form a filter cavity in the sewage filter box, and the sewage is filtered through the filter cavity. It can be understood that adding zeolite or calcium sulfite and other filter materials in the filter cavity can further enhance the filtering effect of the sewage filter tank 206. A spring clamping device 410 is provided between the scraper 400 and the wall-climbing chassis 100 to ensure close contact between the scraper 400 and the wall surface, so that the scraper 400 can scrape the residual sewage on the wall surface more thoroughly. It can be understood that in the specific implementation, the scraper 400 is made into a curved shape to facilitate the collection of the cleaning sewage collected by the scraper 400 to the middle of the scraper 400, which is convenient for the water storage component 208 to store water; a silicone strip is arranged on the scraper 400 to make the scraper 400 more solid and easy to scrape, so that the wall surface is cleaner after cleaning.

[0044] The main roller brush plate 212 and the auxiliary roller brush plate 213 both include a roller brush plate upper cover 2121, a roller brush plate lower cover 2122 connected to a rotating shaft 2123 of the roller brush plate upper cover 2121, and a motor for driving the rotating shaft 2123 to rotate. The end of the roller brush plate lower cover 2122 is provided with the brush 2124. In a specific implementation, the motor drives the rotating shaft 2123 to rotate, and the rotating shaft 2123 drives the roller brush plate lower cover 2122 to rotate. The brush 2124 at the end of the roller brush plate lower cover 2122 rotates to clean the wall surface.

[0045] The cleaning mechanism is provided in plurality, and the plurality of cleaning mechanisms are arranged along the circumference of the wall-climbing chassis 100. It can be understood that the cleaning efficiency can be further improved by providing a plurality of cleaning mechanisms and arranging the plurality of cleaning structures along the circumference of the wall-climbing chassis 100.

[0046] It is understandable that in order to achieve the safe adsorption, movement and cleaning functions of high-altitude curtain wall cleaning equipment, in addition to the reasonable coordination of various devices, energy supply should also be available. According to the working needs of the high-altitude curtain wall cleaning equipment, a wiring power supply can be selected. When the cleaning equipment is required to be convenient, lithium-ion batteries are preferred as energy supply.

[0047] In this embodiment, it needs to be further explained that the motor, worm motor 2144 and drive motor in the curtain wall cleaning device are turned on and off by manual control, and can also be automatically controlled by a single chip microcomputer.

[0048] In this embodiment, it needs to be further explained that in order to improve the safety of the high-altitude curtain wall cleaning equipment, a distance measuring sensor device 500 can be set on the wall climbing chassis 100. The distance measuring sensor can be used to monitor in real time the distance at which the high-altitude cleaning equipment is adsorbed on the wall surface, thereby determining whether the high-altitude cleaning equipment is safely adsorbed on the high-altitude curtain wall, making it convenient for operators to control the high-altitude curtain wall cleaning equipment.

[0049] In summary, the high-altitude curtain wall cleaning equipment in the above-mentioned embodiment of the present invention is adsorbed on the high-altitude curtain wall by the wall-climbing chassis 100, and a main roller brush disc 212 and an auxiliary roller brush disc 213 are arranged on the scrubbing arm 211. The high-altitude curtain wall is cleaned by rotating the brushes 2124 on the main roller brush disc 212 and the auxiliary roller brush disc 213. During cleaning, the two auxiliary roller brush discs 213 swing relative to each other along the scrubbing arm 211, thereby further improving the cleaning efficiency. By arranging a pneumatic rod 300 between the wall-climbing chassis 100 and the scrubbing arm 211, when facing an uneven high-altitude curtain wall, the height of the scrubbing arm 211 can be adjusted so that the roller brush disc and the wall surface always maintain an optimal contact distance, thereby further improving the cleaning effect of the high-altitude curtain wall cleaning equipment. In addition, there is no need to manually climb to the high-altitude curtain wall to perform operations during the entire cleaning process, thereby improving safety. This high-altitude curtain wall cleaning equipment solves the problems of low efficiency and low safety in cleaning high-altitude curtain walls in traditional technologies.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
