Remote water supply equipment

Abstract

The invention discloses remote water supply equipment which comprises a travelling trolley, wherein the travelling trolley is provided with an engine, a pressurizing pump, an engine cooler and a water tank. One end of an engine crankshaft is connected with a pump shaft of the pressurizing pump through a clutch while the other end of the engine crankshaft is connected with a pump shaft of a hydraulic pump through a coupler to drive the pump shaft to rotate; the hydraulic pump is further connected with a submerged water-taking pump through an oil path to drive the submerged water-taking pump to operate; the submerged water-taking pump is provided with a floater. When the submerged water-taking pump is arranged in water, the submerged water-taking pump can float on the water level by the buoyancy of the floater; a water outlet pipe of the submerged water-taking pump is communicated with the water tank and a water inlet pipe of the pressurizing pump is further communicated with the water tank. The remote water supply equipment disclosed by the invention can dispatch the water from a remote water source to a scene of fire to continuously supply the water to fire fighting. In addition, one engine can drive all compoments at the same time, so that the equipment provided by the invention is simple in structure and low in cost.

Description

technical field [0001] The invention relates to remote water supply equipment, in particular to a remote water supply equipment used for fire fighting and extinguishing when a large-scale fire occurs in a petrochemical area. Background technique [0002] At present, in the design of fire protection systems in petrochemical areas (refinery or storage), the fire water volume is usually designed based on the sum of the maximum fire water volume and auxiliary cooling water volume, and the fire extinguishing time (hydrants and fire monitors) is 6 hours. However, in actual fire fighting, especially for liquefied petroleum gas or refined oil depots, once a fire occurs, it often causes an explosion, which can cause multiple fires. The vehicle has limited water storage, and there is no continuous water source for firefighting or maintaining passageway isolation. In many cases, we can only wait helplessly for the flame to extinguish automatically when the combustibles are burned out...

AI Technical Summary

Problems solved by technology

However, due to the characteristics of the water pump, the self-priming capacity of the water pump is affected by the atmospheric pressure of only 0.1MPa and the cavitation of the pump. The self-priming capacity of general large-scale water pumps will not exceed 5m, and the head of the self-priming pump is relatively low.

On the shores of rivers, rivers, lakes, seas, reservoirs, etc., the drop between the position that the trailer pump can reach and the water level is often high. It is difficult for ordinary trailer pumps to absorb water. There is no water delivery effect, and it is impossible to achieve large flow water supply
