Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) airborne systems, and in particular to an UAV airborne high-altitude cleaning system. Background Technology
[0002] As an important part of modern urban services, the high-altitude cleaning industry has developed rapidly in recent years with the acceleration of urbanization and the popularization of glass curtain wall buildings. At present, the high-altitude cleaning field mainly relies on aerial work platforms or suspended platforms for manual operation, which generally suffers from problems such as poor safety, low efficiency, limited scenarios, and insufficient economy. However, the industry still relies heavily on traditional manual operation mode. Most cleaning work is still completed by carrying people on aerial work platforms or suspended platforms, which has significant safety hazards and efficiency bottlenecks. Suspended platform operations are significantly affected by factors such as wind force and equipment aging, resulting in high operational risks. Although aerial work platforms have good stability, blind spots often appear in complex building structures, forcing operators to adopt dangerous postures. Utility Model Content
[0003] The purpose of this invention is to provide an unmanned aerial vehicle (UAV)-borne high-altitude cleaning system that enables high-altitude cleaning via UAV, eliminating the need for manual high-altitude operations and providing an efficient and environmentally friendly solution for the field of high-altitude cleaning.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an unmanned aerial vehicle (UAV) airborne high-altitude cleaning system, comprising a water tank and a frame assembly. The water tank is positioned above the frame assembly, and a high-pressure water pump is installed inside the frame assembly. A spray pipe is installed at the front of the frame assembly, and a nozzle is connected to the spraying end of the spray pipe. The outlet of the water tank is connected to the inlet of the high-pressure water pump via a first water pipe, and the outlet of the high-pressure water pump is connected to the spray pipe via a second water pipe. A dual-axis servo motor assembly for controlling the pitch and oscillation of the spray pipe and the water basin is installed at the front end of the frame assembly. A waterproof control box is installed inside the frame assembly, and the control box is electrically connected to the high-pressure water pump.
[0005] Furthermore, the frame assembly includes a left frame and a right frame, which are arranged opposite each other. The front and rear ends of the left and right frames are connected by connecting rods. A placement plate is fixed below the left and right frames, and an mounting plate is provided above the left and right frames.
[0006] Furthermore, both the left and right frames are provided with side cover plates, and the side cover plates are provided with switch holes.
[0007] Furthermore, the dual-axis servo assembly includes a pitch servo, a horizontal servo, and a swivel plate. The swivel plate is hinged to the front end of the mounting plate. The pitch servo is fixed below the mounting plate. The output end of the pitch servo is connected to the lower surface of the swivel plate via a first linkage arm. The horizontal servo is fixed to the lower end of the swivel plate. The output end of the horizontal servo passes through the swivel plate and is connected to a second linkage arm. A fixing component is provided on the swivel plate via a rotating member. The other end of the second linkage arm is connected to the fixing component.
[0008] Furthermore, the fixing assembly includes a long plate and a hand-tight quick-release pipe clamp, the hand-tight quick-release pipe clamp being fixed to the front and rear ends of the long plate, and the nozzle being disposed inside the hand-tight quick-release pipe clamp.
[0009] Furthermore, the rotating component includes a support base and a support plate. The support plate is fixed to the bottom of the swing plate by a fixing column. The swing plate and the support plate have fixing holes with opposite positions. The support base is set in the fixing holes by a bearing.
[0010] Furthermore, the nozzle is detachably connected to a spray head.
[0011] Furthermore, the nozzle is a fan-shaped nozzle, a columnar nozzle, or an atomizing nozzle.
[0012] Furthermore, it also includes a small hydraulic spring, the fixed end of which is movably connected to the swing plate, and the telescopic end of which is movably connected to the placement plate.
[0013] Furthermore, the water tank is equipped with a filter screen inside, and a flow guide slope is provided at the bottom of the water tank.
[0014] The beneficial effects of this utility model are as follows: After the system is carried by a drone to a predetermined altitude, a high-pressure water pump pressurizes the water in the tank, and the water is precisely directed to the cleaning surface through a nozzle. Pitch and horizontal angle adjustments are achieved through the coordinated operation of dual servo motors. With interchangeable nozzles (fan-shaped / columnar / atomizing), it adapts to the cleaning needs of different surface materials. Furthermore, it can be used with existing technologies such as preset programs to perform reciprocating automated operations with controllable nozzles. Compared to traditional aerial work platforms or manual suspended platforms for cleaning, this system operates unmanned, completely replacing high-risk manual cleaning at heights. It eliminates the risks of falls and electric shocks, significantly improving operational safety and eliminating the risk of personnel falling from heights. Its high-speed operation and automated cleaning efficiency are several times that of manual cleaning, making it particularly suitable for the non-destructive cleaning of irregularly shaped structures such as wind turbine blades and power transmission insulators. It solves cleaning problems that traditional equipment cannot reach, such as wind turbine blades, high-voltage tower insulators, and ultra-high-altitude glass curtain walls. Deployment costs are drastically reduced, eliminating the need for aerial work platforms / scaffolding and saving on equipment rental fees. Its water-saving design and modular quick-repair mechanism lower maintenance costs, resulting in even lower long-term operating costs. This device provides an efficient and environmentally friendly solution for the field of aerial cleaning and has broad application prospects in infrastructure maintenance and new energy equipment upkeep.

A waterproof control box 6 is installed inside the frame assembly 4. The control box is electrically connected to the high-pressure water pump 7. The frame assembly 4 is detachably connected to the drone. The high-pressure water pump 7 is a miniature plunger-type water pump with a built-in pressure detection module for overpressure protection. It works in conjunction with shock-absorbing pads to isolate the drone from the outer platform, reducing the impact of vibration on the drone. The nozzle 3 is linked with the servo system to dynamically adjust the spray angle, adapting to high-frequency oscillations in high-intensity working environments. This system can also support system start-stop control based on an embedded controller and remote wireless control module, with preset cleaning modes such as left-right reciprocating oscillation cleaning, up-down reciprocating oscillation cleaning, and rotational oscillation cleaning. It monitors the system status (water pressure, flow rate, servo angle, etc.) in real time, automatically triggering emergency shutdown protection in abnormal states. Remote control using a controller and remote wireless control module is existing technology, well understood by those skilled in the art, and will not be described in detail here. This application can also install a camera at the front end of the frame assembly 4 to determine the cleaning position using real-time images captured by the camera. The system includes a water tank 1 and a frame assembly 4 mounted on the drone. The frame assembly 4 is detachably connected to the drone.
