Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] exist figure 1 Among them, after the single-chip microcomputer receives the control signal from the remote controller through the radio frequency receiving module, the single-chip microcomputer drives the motor forward (reverse rotation) circuit through the relay A (relay B), and the motor (2) is mechanically connected with the screw (3). (2) Output the torque according to the control signal requirements, and make the electric valve spool (7) move axially through the screw (3) and nut (4), thereby changing the flow between the water inlet (5) and the water outlet (6) The cross-sectional area is used to adjust the flow rate and implement fire extinguishing.

Abstract

The invention discloses a flow rate controllable distance type indoor fire hydrant. A secondary remote control electrically operated valve is additionally arranged between a conventional fire hydrant water outlet and a conventional water hose; a remote controller is electrically connected with a single-chip microcomputer in a wireless manner; a circuit of the single-chip microcomputer is electrically connected with two relays; the two relays are electrically connected with the positive and negative rotation circuits of a motor of the electrically operated valve respectively to control positive rotation or negative rotation of the motor of the electrically operated valve; the opened range of the valve is regulated; the intensity of flow rate is regulated.

Description

Technical field [0001] The invention relates to the improvement of an indoor fire hydrant, in particular to an indoor fire hydrant with controllable flow and remote control which is convenient for one person to operate and use. Background technique [0002] The working principle and operation method of the indoor fire hydrant water supply system are as follows: when a fire is discovered, the person opens the fire hydrant door, presses the fire alarm button, which sends a fire alarm signal to the fire control center or remotely starts the fire pump, and then quickly pulls Out of the hose, water gun (or fire hose), connect one end of the hose to the outlet of the fire hydrant, and the other end to the water gun, spread (swing) the hose, turn the hand wheel of the fire hydrant to open the water valve, and hold the water gun (most It is best for two people to cooperate), and the jet produced by the water gun (or hose) will shoot the water to the fire point to extinguish the fire...
