Fire hydrant for social public safety

Abstract

The invention discloses a fire hydrant for social public safety. Key points of the technical scheme are as follows: the fire hydrant comprises a fire hydrant body arranged on a wall; a supporting plate is fixedly welded to the outer portion of the fire hydrant body. A first pipeline is fixedly mounted above the supporting plate; a cross-shaped rod is fixed in the first pipeline; a servo motor is fixed on the cross-shaped rod; a first fixing rod is fixed to the end of a motor shaft of the servo motor, the first fixing rod is rotatably connected into the cross-shaped rod, a second fixing rod isdetachably connected to the end of the first fixing rod, a supporting sleeve is connected to the outer portion of the second fixing rod in a threaded mode, and a plurality of exhaust fan blades are fixed to the supporting sleeve; when the fire hydrant for social public safety is used, the fire hydrant can be used as a water supply source and can also be used for exhausting indoor smoke, certain indoor smoke can be exhausted, and smoke accumulation during indoor fire disasters can be reduced.

Description

technical field [0001] The invention belongs to the technical field of firefighting equipment, and in particular relates to a fire hydrant used for social public safety. Background technique [0002] Fire hydrants are divided into indoor fire hydrants and outdoor fire hydrants, which are connected through a water pipe network, and can be connected to water pipes to extinguish the fire in case of fire.
