Underground fire fighting device with double water outlets which is easily buried

Abstract

The invention discloses an underground fire fighting device with double water outlets which is easily buried.The device comprises a box body, a fixing frame and a plug body, the bottom of the box bodyis fixedly connected with the fixing frame, a cavity is formed in the fixing frame, a driving motor is fixedly mounted on the bottom of the cavity, an outlet shaft of the driving motor is fixedly connected to one end of a screw rod, an inner wall of the fixing frame is movably connected with a movable block,the top end of the movable block is fixedly provided with the plug body, the other end ofthe screw rod penetrates through the movable block,thescrew rod is in screwed connection with the movable block, and connecting blocksare fixedly connected to the left and right sides of the fixing frame. The underground firefighting device drives the up-and-down movement of the movable block and the plug body thereon by the forward and reverse rotation of the screw rod, so that the up-and-down movement of the plug body is not only very rapid, but also very stable.

Description

technical field [0001] The invention relates to a fire hydrant, in particular to an underground fire-fighting device with double water outlets which are easy to be buried. Background technique [0002] Fire hydrant, officially called fire hydrant, is a fixed fire-fighting facility whose main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. There are indoor fire hydrants and outdoor fire hydrants. [0003] The existing hydraulically driven underground fire hydrants have the following three problems. First: the existing underground fire hydrants need to dig a large pit to place the box underground, which is very troublesome, and it is also difficult for pedestrians on the bottom to step on the fire hydrants It is easy to cause the tilt of the underground fire hydrant, making it difficult to open the cover plate on the top of the box; second: the hydraulic drive drives the fire hydrant to move up and down, because th...

[0003] The existing hydraulically driven underground fire hydrants have the following three problems. First: the existing underground fire hydrants need to dig a large pit to place the box underground, which is very troublesome, and it is also difficult for pedestrians on the bottom to step on the fire hydrants It is easy to cause the tilt of the underground fire hydrant, making it difficult to open the cover plate on the top of the box; second: the hydraulic drive drives the fire hydrant to move up and down, because the hydraulic pressure starts slowly, which leads to the slow movement of the fire hydrant and affects Extinguish the fire in time; third: the existing fire hydrants generally only have one outlet pipe, which can only be connected to one water pipe, which is inconvenient for many people to control multiple water pipes to extinguish the fire
