Abstract
Description
Technical Field
[0001] This utility model relates to a high-altitude cleaning device for drones, belonging to the field of drone technology. Background Technology
[0002] During actual use, the exterior of glass curtain walls often accumulates dust and other debris. To maintain good light transmission, regular cleaning of the glass curtain wall facade is necessary. Cleaning building exteriors or curtain walls is crucial for maintaining a clean building appearance, and primarily includes two methods: manual cleaning and mechanical cleaning. Manual cleaning involves workers using ropes, baskets, and other tools, holding cleaning tools (such as rags and brushes) and cleaning agents to wipe the wall surface. This method is suitable for complex designs or small-area curtain walls, but it is inefficient and dangerous.
[0003] Mechanical cleaning primarily utilizes equipment such as exterior wall cleaning machines, employing high-pressure water jets or rotating brush heads for cleaning. It is highly efficient and suitable for large, flat exterior walls. However, the increasingly popular aerial drone cleaning methods also suffer from similar drawbacks to mechanical cleaning, such as their inability to handle complex building facades or small curtain wall areas. Utility Model Content
[0004] The purpose of this invention is to solve the technical problem that existing technologies cannot adapt to cleaning complex building facades and small-area curtain walls, and to provide a drone-based high-altitude cleaning device.
[0005] This utility model is achieved through the following technical solution:
[0006] The present invention relates to a drone high-altitude cleaning device, comprising a drone body, two support arms mounted on one side of the drone body, a vertical plate fixedly mounted at the end of the support arms, a bidirectional cylinder mounted on the back of the vertical plate, a strip-shaped hole on the vertical plate, two support arms mounted in the strip-shaped hole, one end of the support arms being connected to the bidirectional cylinder, two movable brush rollers mounted between the other ends of the two support arms, a retractable spray pipe being provided between the two support arms, and a fixed brush roller mounted on the back of the vertical plate via two support rods.
[0007] The operator controls the drone to fly to the curtain wall to be cleaned. The brush rollers are pressed against the curtain wall, and the drone is raised and lowered vertically. The length of the telescopic spray pipe and the distance between the two moving brush rollers can be controlled by a two-way cylinder to move the two support arms. When the distance between the two moving brush rollers reaches its maximum, the length of the fixed brush roller is not less than the maximum focal length at this time, ensuring that no part of the cleaning is missed during the up and down movement. At the same time, the telescopic spray pipe sprays water onto the curtain wall cleaned by the brush rollers, which can adapt to the complex building facades and narrow curtain walls.
[0008] Further optimization involves a retractable scraper hinged to the top of the vertical panel. The end of the retractable scraper away from the vertical panel is flush with the surface. A one-way cylinder is hinged to the back of the retractable scraper, and the other end of the one-way cylinder is hinged to a reinforcing rod fixed between the two arms. After the curtain wall is cleaned by brush rollers and sprayed with water by the retractable spray pipes, some water stains will appear to varying degrees after it dries naturally. The retractable scraper can clean these water stains from the curtain wall.
[0009] In a further preferred embodiment, the two movable brush rollers are connected by a telescopic rod.
[0010] Further optimized, the movable brush roller and the fixed brush roller are arranged in a staggered vertical arrangement and are flush front to back in the vertical direction. This ensures that there is no interference between the movable and fixed brush rollers and also guarantees a good fit with the curtain wall.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The operator controls the drone to fly to the curtain wall to be cleaned. The brush rollers are pressed against the curtain wall, and the drone is raised and lowered vertically. The length of the telescopic spray pipe and the distance between the two moving brush rollers can be controlled by a two-way cylinder to move the two support arms. When the distance between the two moving brush rollers reaches its maximum, the length of the fixed brush roller is not less than the maximum focal length at this time, ensuring that no part of the cleaning is missed during the up and down movement. At the same time, the telescopic spray pipe sprays water onto the curtain wall cleaned by the brush rollers, which can adapt to the complex building facades and narrow curtain walls.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0019] like Figs. 1 to 3 The above-displayed drone high-altitude cleaning device includes a drone body 1. Two support arms 2 are mounted on one side of the drone body 1. A vertical plate 5 is fixed at the end of each support arm 2. A bidirectional cylinder 4 is mounted on the back of the vertical plate 5. A strip-shaped hole 6 is opened on the vertical plate 5, and two support arms 7 are arranged in the strip-shaped hole 6. One end of each support arm 7 is connected to the bidirectional cylinder 4. Two movable brush rollers 8 connected by telescopic rods 9 are installed between the other ends of the two support arms 7. A telescopic spray pipe 12 is provided between the two support arms 7. One end of the telescopic spray pipe 12 is connected to a water supply pipe 13, which extends to the ground and is connected to a water source on the ground. A fixed brush roller 10 is mounted on the back of the vertical plate 5 through two support rods 11. A motor for driving the fixed brush roller 10 to rotate is mounted on the support rods 11. A motor for driving the movable brush rollers 8 to rotate is mounted on the support arms 7.
[0020] The operator controls the drone body 1 to fly to the curtain wall to be cleaned. The brush rollers are close to the curtain wall. The drone body 1 is then raised and lowered vertically. The length of the telescopic spray pipe 12 and the distance between the two moving brush rollers 8 can be achieved by the two-way cylinder 4 driving the two support arms 7 to move. When the distance between the two moving brush rollers 8 reaches its maximum, the length of the fixed brush roller 10 is not less than the maximum focal length at this time, ensuring that there will be no omissions in the vertical cleaning. At the same time, the telescopic spray pipe 12 sprays water to clean the curtain wall cleaned by the brush rollers. It can adapt to the complex building facades and narrow curtain walls.
[0021] A retractable scraper 15 is hinged to the top of the vertical plate 5. The end of the retractable scraper 15 away from the vertical plate 5 is flush with the plate. The retractable scraper 15 is extended and retracted by a bidirectional electric telescopic rod 16 installed on it. A one-way cylinder 14 is hinged to the back of the retractable scraper 15. The other end of the one-way cylinder 14 is hinged to a reinforcing rod 3 fixed between the two arms 2. After the curtain wall is cleaned by brush rollers and sprayed with water by the retractable spray pipe 12, some water stains will appear after it dries naturally. The retractable scraper 15 can clean the water stains on the curtain wall.
[0022] The movable brush roller 8 and the fixed brush roller 10 are staggered vertically and aligned front to back vertically. This ensures that there is no interference between the movable brush roller 8 and the fixed brush roller 10, and also ensures a good fit with the curtain wall.
[0023] Working principle:
[0024] The operator controls the drone body 1 to fly to the curtain wall to be cleaned. The brush rollers are pressed against the curtain wall. The drone body 1 is then raised and lowered vertically. The length of the telescopic spray pipe 12 and the distance between the two moving brush rollers 8 can be achieved by the two-way cylinder 4 driving the two support arms 7 to move. When the distance between the two moving brush rollers 8 reaches its maximum, the length of the fixed brush roller 10 is not less than the maximum focal length at this time, ensuring that there will be no omissions in the vertical cleaning. At the same time, the telescopic spray pipe 12 sprays water to clean the curtain wall cleaned by the brush rollers. The one-way cylinder 14 drives the telescopic scraper 15 to flip, so that the telescopic scraper 15 is pressed against the surface of the curtain wall, which can adapt to the complex building facades and narrow curtain walls.
