With the acceleration of urbanization, cleaning and maintenance issues of high-altitude buildings, bridges, power facilities, etc. have become increasingly prominent. Traditional manual cleaning methods are not only inefficient and costly, but also pose safety risks in high-altitude operations. High-pressure water jet cleaning technology carried by drones has emerged as the times require, and with its unique advantages, it has become a new solution to this problem. This technology uses a high-pressure water jet device on a drone platform to achieve long-distance, high-altitude, and precise cleaning operations, with the advantages of high operating efficiency, low cost, and good safety.

System Composition

The high-pressure water spray cleaning system carried by drones is mainly composed of drone platform, high-pressure water spray device, control system, water supply system, data transmission and monitoring system, etc. The drone platform is responsible for carrying other components and providing flight capabilities; the high-pressure water spray device is the core of the cleaning task; the control system ensures that the drone flies stably and performs cleaning operations according to the predetermined trajectory; the water supply system provides a stable water flow for the water spray device; the data transmission and monitoring system transmits the operation screen and data in real time, which is convenient for ground operators to monitor and adjust.

High Pressure Water Spraying Device

The high-pressure water spray device is the core component of the system, usually composed of a high-pressure pump, a nozzle, a water pipe, etc. The high-pressure water flow generated by the high-pressure pump is transported to the nozzle through the water pipe. The nozzle is designed with a specific spray angle and flow rate to achieve a precise cleaning effect. The selection of the nozzle needs to be adjusted according to the different cleaning objects to achieve the best cleaning effect.

Auxiliary Equipment

In addition to the above main components, the high-pressure water jet cleaning system carried by the drone also needs to be equipped with some auxiliary equipment, such as GPS positioning system, obstacle avoidance sensor, camera, etc. The GPS positioning system ensures that the drone flies according to the predetermined trajectory; the obstacle avoidance sensor helps the drone fly safely in complex environments; the camera transmits the operation picture in real time for ground operators to monitor.

Security Analysis

The high-pressure water jet cleaning technology carried by drones has significant advantages in terms of safety. First, drone flight operations reduce the risks of manual high-altitude operations; second, through precise control systems and auxiliary equipment, collisions with the cleaning objects can be effectively avoided; finally, the system has fault self-detection and emergency handling functions. Once an abnormal situation occurs, the operation can be stopped immediately and measures can be taken to protect the safety of drones and personnel.

Application Scenario

This technology is widely used in various fields of urban cleaning and maintenance, such as glass curtain wall cleaning of high-altitude buildings, bridge surface cleaning, rust removal and corrosion prevention of power facilities, etc. In addition, it can also be used for pest control spraying operations in agriculture and forestry, and aerial firefighting in the field of firefighting.

Operation and Effect

In terms of operation, the high-pressure water jet cleaning system carried by drones usually operates in remote control or autonomous flight mode. After the ground operator sets the flight route and cleaning parameters through the control system, the drone can automatically complete the cleaning task. In terms of cleaning effect, since the high-pressure water flow has strong impact and penetration, it can quickly remove dirt and attachments attached to the surface of the cleaning object and restore its original cleanliness and glossiness. With the continuous development and improvement of drone technology and high-pressure water jet technology, the high-pressure water jet cleaning technology carried by drones will be applied and promoted in more fields. In the future, this technology is expected to further improve cleaning efficiency and quality, reduce operating costs, enhance safety performance, and combine with other intelligent technologies to form a more efficient and intelligent cleaning and maintenance solution. At the same time, with the improvement of environmental awareness and the promotion of policies, green and environmentally friendly cleaning methods will also become an important trend in future development.
