Description

Technical Field

[0001] This utility model relates to the field of architectural glass cleaning technology, specifically a ducted propeller-driven adsorption cleaning robot. Background Technology

[0002] With the rapid increase in the number of high-rise buildings worldwide, the cleaning and maintenance of building facade glass has become a crucial issue in modern urban operations. Traditional cleaning methods mainly rely on two modes: manual climbing and aerial work platforms. The former requires cleaning personnel to wear professional rope equipment for suspended operations, posing significant safety hazards such as falls from heights and injuries from broken glass. While the latter reduces some risks through lifting equipment, its daily work efficiency is low due to limitations in equipment size, site conditions, and weather factors. This high-risk, low-efficiency, and high-cost operating mode can no longer meet the needs of modern dense and large-scale building development, necessitating the exploration of safer and more efficient alternatives.

[0003] In existing technologies, when the cleaning target is a high-rise building with window sills, the traditional adsorption method makes it difficult for the cleaning robot to get close to the glass due to the gap between the cleaning robot and the glass surface, resulting in blind spots. Furthermore, existing cleaning robots are difficult to accurately position in complex facade environments (such as concave and convex window sills and corner structures), posing a risk of collision or "stepping into the air". To address this, we propose a ducted propeller adsorption cleaning robot. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a ducted propeller-driven suction cleaning robot. Utilizing ducted propellers at the four corners of the top, the distance between the robot and the glass surface can be quickly adjusted, effectively overcoming distance obstacles caused by structures such as window sills. This ensures that the negative pressure suction cup and cleaning rollers are in close contact with the glass. Front and rear detection cameras and radars scan the building facade outline in real time, proactively avoiding obstacles such as window sills and corners, preventing collisions and the risk of missteps, and solving the background problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ducted propeller-driven suction cleaning robot, comprising a robot body, two sets of drive tracks symmetrically mounted on the front and rear sides of the robot body, a cleaning wheel cover mounted on the right side of the robot body, a cleaning roller rotatably mounted inside the cleaning wheel cover, ducted propellers fixedly mounted at the four corners of the top of the robot body, several negative pressure suction cups mounted on the bottom of the robot body, an installation port opened on the top right side of the robot body, an air filter assembly for the negative pressure suction cups installed inside the installation port, and a hanging assembly also mounted on the top of the robot body.

[0006] Preferably, the air filtration assembly includes a filter cartridge, which is installed inside the mounting port. A sealing cap is threaded onto the top of the filter cartridge. An air filter is installed inside the filter cartridge. An air outlet pipe is fixedly connected to the bottom of the filter cartridge. An air inlet pipe is fixedly connected to the top left side of the filter cartridge. Several air inlets are provided on the air inlet pipe. The air inlets are fixedly connected to a negative pressure suction cup through a pipe.

[0007] Preferably, the suspension assembly includes two sets of crossbeams, with hooks fixedly connected to the front and rear sides of both sets of crossbeams. Ground safety ropes are wound around the two sets of hooks on the front side, and suspension ropes are wound around the two sets of hooks on the rear side.

[0008] Preferably, a detection camera and a detection radar are installed on the left side of the robot body and the right side of the cleaning wheel cover.

[0009] Preferably, two sets of mounting rods are fixedly connected to the front and rear sides of the robot body, and side guide wheels are rotatably mounted on the ends of the four sets of mounting rods away from the robot body.

[0010] Preferably, an air outlet is provided at the center of the top side of the robot body.

[0011] Preferably, a tethered universal interface is installed on the top left side of the robot body.

[0012] This invention provides a ducted propeller-driven adsorption cleaning robot. Compared with the prior art, it has the following advantages:

[0013] 1. This ducted propeller-driven suction cleaning robot utilizes ducted propellers at the four corners of the top to quickly adjust the distance between the robot and the glass surface, effectively overcoming distance obstacles caused by structures such as window sills, ensuring that the negative pressure suction cup and cleaning rollers are in close contact with the glass, and front and rear detection cameras and radars scan the building facade outline in real time to avoid obstacles such as window sills and corners in advance, avoiding the risk of collision and misstepping.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a ducted propeller adsorption cleaning robot, including a robot body 1, two sets of drive tracks 2 symmetrically installed on the front and rear sides of the robot body 1, a cleaning wheel cover 3 installed on the right side of the robot body 1, a cleaning roller 17 rotatably installed inside the cleaning wheel cover 3, ducted propellers 8 fixedly installed at the four corners of the top of the robot body 1, a number of negative pressure suction cups 16 installed at the bottom of the robot body 1, an installation port 6 opened on the top right side of the robot body 1, an air filter assembly for the negative pressure suction cups 16 installed inside the installation port 6, and a hanging assembly installed on the top of the robot body 1.

[0023] When the cleaning robot is working, the rooftop reel is connected to the hanging assembly on the top of the robot body 1, which can drive the robot body 1 to rise and fall. The drive tracks 2 on the front and rear sides of the robot body 1 are responsible for moving on the glass surface. After the ducted thrusters 8 at the four corners of the top are activated, they can push the robot body 1 onto the glass surface. At this time, the negative pressure suction cup 16 at the bottom is fixed by the air filter assembly, so that the robot body 1 is close to the glass. The cleaning roller 17 rotating inside the cleaning wheel cover 3 on the right side performs the cleaning operation on the glass.

[0024] The air filtration assembly includes a filter cartridge 18, which is installed inside the mounting port 6. A sealing cap 19 is threaded onto the top of the filter cartridge 18. An air filter is installed inside the filter cartridge 18. An air outlet pipe 20 is fixedly connected to the bottom of the filter cartridge 18. An air inlet pipe 21 is fixedly connected to the top left side of the filter cartridge 18. Several air inlets 22 are provided on the air inlet pipe 21. The air inlets 22 are fixedly connected to the negative pressure suction cup 16 through pipes.

[0025] When the air filtration assembly is working, air enters the air inlet pipe 21 through the air inlet 22 when the negative pressure suction cup 16 is activated. After being filtered by the air filter in the filter box 18, it is discharged through the air outlet pipe 20, thereby purifying the airflow and maintaining the efficient operation of the negative pressure system. The filter box 18 is installed in the installation port 6 and the top is fixed by the sealing cover 19 with threads, which facilitates the replacement of the air filter.

[0026] The suspension assembly includes two sets of crossbeams 4, with hooks 5 fixedly connected to the front and rear sides of the two sets of crossbeams 4. Ground safety ropes 15 are wound around the two sets of hooks 5 on the front side, and suspension ropes 14 are wound around the two sets of hooks 5 on the rear side.

[0027] When the suspension assembly is in operation, the suspension rope 14 of the rooftop cable reel is wound around the two sets of hooks 5 on the rear side, and the ground safety rope 15 is wound around the two sets of hooks 5 on the front side. The two sets of crossbeams 4 form a double safety connection through the hooks 5 to ensure the suspension stability of the robot body 1 when it is working at height.

[0028] Both the left side of the robot body 1 and the right side of the cleaning wheel cover 3 are equipped with detection cameras 10 and detection radars 11, which scan the building facade structure in front in real time, detect obstacles or changes in spacing, and provide environmental data for the movement of the robot body 1 to avoid risks.

[0029] Two sets of mounting rods 12 are fixedly connected to the front and rear sides of the robot body 1. Side guide wheels 13 are rotatably mounted on the ends of the four sets of mounting rods 12 away from the robot body 1. When the drive track 2 moves, the side guide wheels 13 rotate to assist in guidance and prevent the robot body 1 from being damaged by collision.

[0030] An air outlet 7 is provided on the top center of the robot body 1 to discharge the airflow processed by the air filter assembly or part of the airflow during the operation of the ducted thruster 8, so as to maintain the air pressure balance inside the body.

[0031] The robot body 1 is equipped with a tethering universal interface 9 on the top left side. The tethering universal interface 9 on the top left side is used to fasten the power cord and water pipe. When the power cord is fastened, the robot body 1 is driven by an external power source, or it can be driven by the power source built into the robot body 1. After the water pipe is fastened, the water pipe moves with the robot body 1, which facilitates the supply of cleaning water.

[0032] Working principle: When the cleaning robot is working, the hoisting rope 14 of the rooftop reel is wound around the two sets of hooks 5 on the rear side, and the ground safety rope 15 is wound around the two sets of hooks 5 on the front side. The two sets of crossbeams 4 form a double safety connection through the upper and lower hooks 5, ensuring the suspension stability of the robot body 1 when working at height and driving the robot body 1 to rise and fall. The drive tracks 2 on the front and rear sides of the robot body 1 are responsible for moving on the glass surface. When it is necessary to clean the exterior glass of a high-rise building, the ducted propellers 8 at the four corners of the top are activated, and the robot body 1 is pushed to the glass surface by wind power. Then, the negative pressure suction cup 16 is activated. The vacuum pump draws air from the bottom of the negative pressure suction cup 16. The air enters the air inlet pipe 21 through the air inlet 22, is filtered by the air filter in the filter box 18, and is discharged through the air outlet pipe 20. This purifies the airflow and maintains the efficient operation of the negative pressure system. The filter box 18 is installed in the mounting port 6 and the top is fixed by the sealing cover 19 with threads, which facilitates the replacement of the air filter. After the negative pressure suction cup 16 is attached to the glass, the robot body 1 is pressed against the glass. The cleaning roller 17 rotating in the cleaning wheel cover 3 on the right side, together with the water pipe attached to the tethered universal interface 9, provides a water source, thereby performing cleaning operations on the exterior glass of high-rise buildings.
