Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall cleaning, in particular to a cleaning device for high-rise building exterior walls. Background Technique

[0002] With the acceleration of the urbanization process, high-rise buildings have emerged in large numbers, and the problem of cleaning their exterior walls has become increasingly prominent. The exterior wall materials of high-rise buildings are diverse, including glass curtain walls, stones, tiles, etc. After being exposed to the natural environment for a long time, these materials are prone to accumulating dust, dirt and pollutants, which not only affect the appearance but may also cause damage to the building materials. Therefore, it is crucial to regularly clean and maintain the exterior walls of high-rise buildings. At present, the traditional cleaning method for high-rise building exterior walls mainly relies on manual high-altitude suspension cleaning.

[0003] In the existing cleaning devices for building exterior walls, when cleaning the exterior wall, after a long time of cleaning, a large amount of dust and stains will accumulate on the cleaning roller. At present, the cleaning roller is mainly cleaned by brushing it in a bucket of clean water to ensure the cleaning effect of the cleaning roller. However, this cleaning method pollutes a large amount of clean water in the bucket, resulting in that after multiple cleanings, the cleaning water in the bucket can no longer achieve the cleaning effect, and the cleaning effect is limited. The existing cleaning roller is not convenient for self-cleaning, resulting in a deterioration of the cleaning effect of the cleaning roller on the building exterior wall. Content of the Utility Model

[0004] To solve the above technical problems, a cleaning device for high-rise building exterior walls is provided. This technical solution solves the problem that the existing cleaning roller is not convenient for self-cleaning, resulting in a deterioration of the cleaning effect of the cleaning roller on the building exterior wall.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A cleaning device for high-rise building exterior walls includes a telescopic rod, and a cleaning mechanism is installed at the top of the telescopic rod. The cleaning mechanism includes an installation shell, two groups of rotating shafts are rotatably connected inside the installation shell, a cleaning roller is fixedly connected between the two groups of rotating shafts, a closed shell is slidably connected inside the installation shell, a water inlet is fixedly connected to the outside of the closed shell, a water outlet is fixedly connected to the side of the closed shell adjacent to the water inlet, a dirt removal component is connected inside the closed shell, and the dirt removal component includes a scraping plate which is slidably connected inside the closed shell.

[0007] Preferably, a sliding track is opened inside the installation shell, the closed shell is slidably connected inside the sliding track, both ends of the closed shell extend to the outside of the sliding track, and a rotating collar is fixedly connected to the left side of the closed shell.

[0008] Preferably, the rotating collar is rotatably connected to the mounting shell. The rotating collar is rotatably connected to the outside of the left shaft, and a driven gear is fixedly connected to the outside of the rotating collar extending from the mounting shell.

[0009] Preferably, the cleaning mechanism further includes a first motor and a second motor. The first motor is fixedly installed on the right side of the mounting shell, and the output end of the first motor extends into the mounting shell and is fixedly connected to the right shaft. The second motor is fixedly installed at the left end of the mounting shell through a motor bracket, and the output end of the second motor is fixedly connected to a driving gear meshing with the driven gear.

[0010] Preferably, sliders are fixedly connected to both the left and right ends of the scraping plate. Sliding grooves adapted to the sliders are formed inside the closed shell, and the sliders are slidably connected to the sliding grooves. A return spring is fixedly connected to the bottom inside the sliding grooves, and the end of the return spring away from the sliding grooves is fixedly connected to the sliders.

[0011] Preferably, an inclined platform is fixedly connected to the upper end of the scraping plate. The inclined platform is slidably connected to the closed shell, and the upper end of the inclined platform extends to the outside of the closed shell.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: By providing a cleaning mechanism, the closed shell can slide out of the outside of the mounting shell and form a closed cylinder with the mounting shell. When the closed shell and the mounting shell form a closed cylinder and clean water is injected, during the self-rotation of the cleaning roller, through the scraping of the scraping plate and the flushing of the clean water, effective cleaning of itself is achieved, ensuring that the cleaning roller always maintains a good cleaning effect, thereby improving the cleaning quality of the building exterior wall. Moreover, by injecting clean water into the cylinder formed by the closed shell and the mounting shell, the cleaning roller can be cleaned by pumping out part of the clean water, preventing the cleaning roller from polluting a large amount of clean water, separating the clean water from the sewage after cleaning, enabling the sewage generated after cleaning the cleaning roller to flow out through the water outlet, reducing the usage amount of clean water, saving water resources, and effectively ensuring the self-cleaning effect of the cleaning roller.

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0024] Embodiment 1

[0025] Please refer to Figures 1-6 As shown, a cleaning device for the outer wall of high-rise buildings includes a telescopic rod 1. A cleaning mechanism 2 is installed at the top of the telescopic rod 1. The cleaning mechanism 2 includes an installation shell 201. Two groups of rotating shafts 208 are rotatably connected to the inner side of the installation shell 201. A cleaning roller 205 is fixedly connected between the two groups of rotating shafts 208. A sealing shell 202 is slidably connected inside the installation shell 201. A water inlet 203 is fixedly connected to the outer side of the sealing shell 202. A water outlet 204 is fixedly connected to the side of the sealing shell 202 adjacent to the water inlet 203. A decontamination component 3 is connected inside the sealing shell 202. The decontamination component 3 includes a scraper 301, and the scraper 301 is slidably connected to the inside of the sealing shell 202.

[0026] In this solution, the telescopic rod 1 can increase the cleaning range of the cleaning mechanism 2, facilitating the use by workers. The water inlet 203 is connected to an external water pump through a pipeline, facilitating the injection of clean water. The water outlet 204 is connected to an external water extraction pump through a pipeline, capable of pumping out the sewage after cleaning. The closed shell 202 can slide out of the outside of the installation shell 201 and form a closed cylinder with the installation shell 201. At this time, clean water is injected into the cylinder through the water inlet 203 until it is full, and through the self-rotation of the cleaning roller 205, the self-cleaning of the cleaning roller 205 can be realized, ensuring the cleaning effect of the cleaning roller 205. The sewage generated after cleaning the cleaning roller 205 flows out through the water outlet 204;

[0027] Furthermore, the scraper 301 can slide to the inside of the closed shell 202 and contact the cleaning roller 205. Through the self-rotation of the cleaning roller 205, the stains on the outside of the cleaning roller 205 can be scraped off, increasing the self-cleaning effect of the cleaning roller 205 and further ensuring the cleaning effect of the cleaning roller 205 on the building exterior wall.

[0028] Embodiment 2

[0029] Please refer to Figures 2-5 As shown, a slideway 210 is provided inside the installation shell 201. The closed shell 202 is slidably connected to the inside of the slideway 210. Both ends of the closed shell 202 extend to the outside of the slideway 210, and a rotating collar 211 is fixedly connected to the left side of the closed shell 202.

[0030] The rotating collar 211 is rotatably connected to the installation shell 201. The rotating collar 211 is rotatably connected to the outside of the left-side rotating shaft 208. The rotating collar 211 extends to the outside of the installation shell 201 and is fixedly connected to a driven gear 212.

[0031] The cleaning mechanism 2 further includes a first motor 206 and a second motor 207. The first motor 206 is fixedly installed on the right side of the installation shell 201. The output end of the first motor 206 extends into the installation shell 201 and is fixedly connected to the right-side rotating shaft 208. The second motor 207 is fixedly installed on the left end of the installation shell 201 through a motor bracket. The output end of the second motor 207 is fixedly connected to a driving gear 209 that meshes with the driven gear 212.

[0032] In this solution, the first motor 206 is electrically connected to an external power supply. The first motor 206 can drive the cleaning roller 205 to rotate, facilitating the cleaning of the exterior wall. The second motor 207 is electrically connected to an external power supply. The second motor 207 can drive the driving gear 209 to rotate, and then drive the rotating collar 211 to rotate through the driven gear 212, thereby driving the closed shell 202 to slide out of the slideway 210 and making the upper part of the closed shell 202 slide into the slideway 210;

[0033] Further, when the cleaning roller 205 cleans the outside, the closed shell 202 slides into the inside of the slideway 210, so that the cleaning roller 205 is exposed outside the mounting shell 201.

[0034] Embodiment 3

[0035] Please refer to Figures 5-6 As shown, both the left and right ends of the scraping plate 301 are fixedly connected with sliders 303. The inner side of the closed shell 202 is provided with a chute 213 adapted to the slider 303. The slider 303 is slidably connected with the chute 213. The inner bottom of the chute 213 is fixedly connected with a return spring 304. One end of the return spring 304 away from the chute 213 is fixedly connected with the slider 303.

[0036] The upper end of the scraping plate 301 is fixedly connected with an inclined platform 302. The inclined platform 302 is slidably connected with the closed shell 202. The upper end of the inclined platform 302 extends to the outside of the closed shell 202.

[0037] In this solution, the cross-sectional shape of the inclined platform 302 is wedge-shaped. When cleaning the cleaning roller 205, the upper part of the closed shell 202 slides to the entrance at the lower end of the slideway 210, thereby driving the dirt removal assembly 3 to slide, so that the inclined surface of the inclined platform 302 abuts against the lower end of the mounting shell 201. Further, under the continuous sliding of the closed shell 202, the inclined platform 302 is extruded, so that the inclined platform 302 slides into the inside of the closed shell 202, and then drives the scraping plate 301 to protrude from the inside of the closed shell 202, facilitating the scraping and cleaning of the stains on the outside of the cleaning roller 205;

[0038] Further, when the closed shell 202 slides into the inside of the mounting shell 201, the upper part of the closed shell 202 is located outside the mounting shell 201. At this time, the return spring 304 can push the slider 303 to drive the scraping plate 301 and the inclined platform 302 to reset

[0039] The working principle and usage process of the present utility model: First, when cleaning the cleaning roller 205, start the second motor 207 and drive the driving gear 209 to rotate. Further, drive the rotating collar 211 to rotate through the driven gear 212, thereby driving the closed shell 202 to slide out of the slideway 210, and making the upper part of the closed shell 202 slide into the inside of the slideway 210, so that the closed shell 202 and the mounting shell 201 form a closed cylinder. At the same time, the inclined platform 302 is extruded by the mounting shell 201, so that the inclined platform 302 slides into the inside of the closed shell 202, and then drives the scraping plate 301 to protrude from the inside of the closed shell 202. At this time, inject clean water into the cylinder through the water inlet 203 until it is full, and through the self-rotation of the cleaning roller 205, with the cooperation of the scraping plate 301 and the clean water, the self-cleaning of the cleaning roller 205 can be realized, effectively ensuring the cleaning effect of the cleaning roller 205 on the outer wall.
