AI Technical Summary

Technical Problem

The water hose carried by the fire-fighting drone was suspended in mid-air above the target window, making it impossible to connect to the fire hydrant inside the building window for water supply.

Method used

A hose retraction system is provided, including a building-side device and a drone-side device. The system utilizes a delivery rod and a clamping mechanism to achieve automatic traction and retraction of the hose. The delivery rod of the building-side device delivers a guide to the clamping mechanism of the drone-side device. The clamping mechanism receives the guide in an open state and clamps it in a closed state. Subsequently, the delivery rod retracts, driving the hose to the vicinity of the building window.

Benefits of technology

It enables the guidance and retraction of water hoses across suspended distances, reducing the risks of manual high-altitude operations and improving the safety and efficiency of fire rescue in super high-rise buildings.

Abstract

The application relates to the technical field of fire rescue equipment, in particular to a water hose pulling system and a water hose pulling method. The water hose pulling system comprises a building side device and a UAV side device; the building side device comprises a first base and a delivery assembly, the delivery assembly comprises a delivery rod and a guide piece, the delivery rod can be extended and retracted towards the UAV side device, and the guide piece is arranged at one end of the delivery rod away from the first base; the UAV side device comprises a second base and a clamping mechanism, the clamping mechanism has an open state and a closed state, the guide piece can be received in the open state, and the guide piece can be clamped in the closed state. The delivery rod delivers the guide piece to the clamping mechanism, the delivery rod is retracted together with the guide piece after being clamped by the clamping mechanism, so that the target water hose at the suspended span is pulled to the vicinity of the building window, and the target water hose is convenient for supplying water to the UAV for fire extinguishing.
