Method and device for rapidly adjusting water yield and effluent pressure of hydraulic monitor of fire engine

Abstract

The invention relates to a fire-fighting technology, and in particular relates a method and device for rapidly adjusting the water yield and effluent pressure of a hydraulic monitor of a fire engine. The existing fire-fighting technology has the following defects: the difficulty of management at the fire scene is serious; the speed for adjusting the water yield and effluent pressure of the hydraulic monitor is slow; and the extinguishing efficiency is low. The method in the invention is that: arranging a controller (11), a pressure sensor (5) arranged on the inlet and outlet of a fire-fighting water pump on the fire engine and a flow rate sensor (9); setting the control parameters of the controller (11); inputting the sensor signals in the controller; and regulating the size of a throttle of an engine automatically, and regulating the rotation speed of the motor and the pressure of the water pump outlet to reach the preset target. The device provided by the invention comprises the controller (11), the pressure sensor (8) of the water pump outlet, the pressure sensor (5) of the water pump inlet and a rotation speed sensor (6). The method and device for rapidly adjusting the water yield and effluent pressure of the hydraulic monitor of fire engine have the advantages that the fire-fighting working efficiency is improved, the extinguishing speed is improved, the fire disaster loss is reduced, and the operation is convenient and easy.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a method and a device for quickly adjusting the water output and water output pressure of a water gun of a fire truck. Background technique [0002] Fire trucks are an important tool for modern firefighting. Various fire trucks are equipped with fire extinguishing tools such as water pumps and fire nozzles. Generally, the working pressure of the water gun is between 0.2MPa and 0.8MPa, the direct impact range can reach 40m, and the water flow is between 2-8 liters per second. In the prior art, at the fire fighting site, the fire commander commands the driver of the fire truck to adjust the engine throttle and the outlet pressure of the water pump according to the fire situation orally or with a walkie-talkie, so as to adjust the water outlet pressure and water output of the fire water gun to achieve the fire extinguishing effect. The prior art has the following disadvanta...
