Abstract

The invention provides a water band pressurizing device, a water band pressurizing method and a fire fighting apparatus. The water band pressurizing device comprises a water flow conveying belt consisting of a plurality of sections of water bands which are mutually communicated, wherein an axial-flow electric pump is arranged at a node between every two adjacent sections of water bands; the axial center of a blade of the axial-flow electric pump is parallel to the water flow direction in the water bands; and the axial-flow electric pump is used for pressurizing water flowing through the node along a water flow direction. After sequentially flowing through the node, the water flow is pressurized in a way of relay, so the problem that it is difficult to delivery water to a high floor during fire fighting is solved. The water band pressurizing device has the advantages of high fire-fighting efficiency, flexible operation, compact structure and the like.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a pressurization device, method and fire protection equipment for a hose. Background technique [0002] With the continuous increase of building height, the operating range of fire fighting equipment is getting larger and larger, and the length of fire hose is also increasing accordingly. For super long fire hoses, the efficiency of fire extinguishing is often affected due to insufficient water pressure. Therefore, those skilled in the art usually install a pressurizing device on the fire fighting equipment to increase the water supply pressure of the hose. [0003] Some of the existing pipeline pumps can increase the water supply pressure of the hose. Its power system is generally driven by electric motors and gasoline engines. The supercharging device is heavy and cumbersome to install. Moreover, in the process of water flow conveying, due to the frictional resistance between...
