Portable tunnel fire fighting equipment based on municipal water supply

Abstract

The invention discloses a portable tunnel fire fighting equipment based on municipal water supply. The portable tunnel fire fighting equipment structurally comprises a spray gun head, an extension pipe, a water flow valve, a water supply pipe, a winding disc, a rotating shaft and a fixing frame. The tail end of the spray gun head is connected with the extension pipe through a flange, the tail end of the extension pipe is connected with the water supply pipe through a flange, and the water supply pipe is connected with the surface of the winding disc in a nested mode. The center of the winding disc is movably matched with the rotating shaft, the center of the rotating shaft is connected with the water supply pipe in a nested mode, the tail end of the water supply pipe is connected with the water flow valve in a nested mode, the water flow valve is in clearance fit with the spray gun head, and the fixing frame is matched with the top end of the water supply pipe in a nested mode. The spray gun head comprises a circulation cavity, a water outlet, a diffuser and a pipe connecting sleeve. After a rotary pressurization rotating disc rotates, a swing blade is pressed into a clamping groove while an inner rotating wheel rotates, so that a rope sliding block covers a cavity of a stop block, the stop block is blocked in a disguised mode, the water flow pressure in an overflow cavity is increased, disguised pressurization is effectively conducted under the condition that the distance is too long and the pressure is insufficient, and sufficient water flow pressure is ensured.

Description

technical field [0001] The invention relates to the municipal field, in particular to a portable tunnel fire-fighting equipment based on municipal water supply. Background technique [0002] Municipal water supply is a part of urban public utilities. Through municipal water system planning within the city, the interconnection of water supply within the city is realized. The municipal water supply system is usually composed of water sources and water plants. After water is taken, it is transported to the water plant through water pipes for water quality treatment. The final water is distributed through the water pipe network through pressurization; [0003] But there are following deficiencies in the prior art: the current portable tunnel fire-fighting equipment based on municipal water supply, because the depth of the tunnel is too long, only a fire-fighting equipment is installed at a certain distance, so a portable and stretchable fire-fighting nozzle is used to cooperate ...

Problems solved by technology

[0003] But there are following deficiencies in the prior art: the current portable tunnel fire-fighting equipment based on municipal water supply, because the depth of the tunnel is too long, only a fire-fighting equipment is installed at a certain distance, so a portable and stretchable fire-fighting nozzle is used to cooperate with the pipeline The extension is carried out, but due to the limitation of the distance, the length of the municipal pressurized water supply is extended, resulting in insufficient internal water flow pressure, which in turn causes the water sprayed by the firefighting equipment to reach the distance.
