Document Type and Number:
WIPO Patent Application WO/2023/045238
Kind Code:
A1
Abstract:
A water hose reel system for use in a drainage emergency vehicle comprises a water hose reel assembly (1), a hydraulic motor (2), a solenoid valve (3), a hydraulic pump (4), a controller (5), and a pressure sensor (6). The hydraulic pump (4) is used to provide power to the hydraulic motor (2), the pressure sensor (6) is used to measure an oil supply pressure of the hydraulic pump (4) and feed back the oil supply pressure to the controller (5), and the controller (5) determines a working state of the water hose reel assembly according to a pressure value, so as to adjust an open or closed state and a flow rate of the solenoid valve (3), and thereby adjust a rotation speed of the hydraulic motor (2). The invention also comprises a method for controlling a water hose reel system for use in a drainage emergency vehicle, and a drainage emergency vehicle. The apparatus and method can improve the operation efficiency and reduce the labor intensity of personnel.
