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
Affiliated technical field
The present invention relates to the improvement of indoor fire hydrant, be especially convenient to the flow-controllable distance type indoor fire hydrant that one man operation is used.
Background technology
The operation principle of indoor fire hydrant water supply system and operation using method are: when finding after fire, open Door for fire hydrant by people, press Fire Alarm Button, send fire alarm signal or start at a distance fire pump to fire protection control center by it, then pull out rapidly water band, hydraulic giant (or hose reel), one, water band is connected with nozzle outlet, other end and hydraulic giant connect, exhibition (getting rid of) boiling water band, rotation fire hydrant handwheel is opened water valve, the hydraulic giant (best two people coordinate) of holding with a firm grip, the jet producing by hydraulic giant (or tap), water-jet is implemented to fire extinguishing to ignition point.Owing to can produce suddenly larger hydraulic pressure in the time opening fire hydrant water valve, therefore simultaneously must be by another person's hydraulic giant of holding with a firm grip, in case hydraulic pressure causes hydraulic giant to touch and wounds other people, but in some cases, as only have a people in the time of scene of fire, cannot use fire hydrant or use difficulty large.
Summary of the invention
In order to overcome the existing single deficiency that cannot operate indoor fire hydrant feedwater fire extinguishing, the present invention has designed a kind of flow-controllable distance type indoor fire hydrant.By setting up secondary remote control electric valve at nozzle outlet and water interband, when one man operation's fire hydrant, first rotate fire hydrant handwheel and open water valve, then launch water band, connect hydraulic giant, hold with a firm grip and hydraulic giant is aimed at after ignition point, open electrically operated valve by Digiplex again, water flow increases gradually, until reach suitable water yield.In fire extinguishing procedure, can be at any time regulate electrically operated valve to open amplitude with water yield adjusting by remote controller, realize the single fire extinguishing of can ease of Use fire hydrant putting out a fire to save life and property.
The technical solution adopted for the present invention to solve the technical problems is: by a kind of flow-controllable distance type indoor fire hydrant, comprise fire hydrant, remote controller, Receiver Module, single chip circuit (MCU), relay, electrically operated valve, electrically operated valve critical piece comprises motor, motor forward/backward rotation control circuit, screw rod, nut, spool, water inlet, delivery port.Remote controller is connected with single chip circuit by wireless mode, single chip circuit and two relay electrical connections, two relays are electrically connected with the motor forward/backward rotation circuit of electrically operated valve respectively, control the motor forward or reverse of electrically operated valve, carry out control valve with this and open amplitude, thus the size of water yield adjusting.
The communication mode of the wireless remote control in this fire hydrant can pass through bluetooth, less radio-frequency, the technology such as infrared realizes.
Electrically operated valve bidirectional interface design in this fire hydrant adopts 50mm and 65mm fire hose snap ring.
The invention has the beneficial effects as follows: can after launching fire hydrant water band, connecting hydraulic giant, open electrically operated valve by wireless remote control mode, and can regulate discharge, in case the injury that high hydraulic pressure causes.Simple in structure, and without existing indoor fire hydrant and fire hose are transformed, RF receiving circuit, single chip circuit, relay, electrically operated valve can be made into one, be directly connected on conventional indoor fire hydrant and use as annex, convenience quick for installation.
Brief description of the drawings
Fig. 1 is flow-controllable distance type indoor fire hydrant schematic diagram.
Reference numeral is as follows:
1: indoor fire hydrant, 2: motor, 3: screw rod, 4: nut, 5: with indoor fire hydrant interface, 6: with hose coupling, 7: spool
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
In Fig. 1, single-chip microcomputer receives after the control signal that remote controller sends by Receiver Module, pass through relay A (relay B) drive motor forward (reversion) circuit by single-chip microcomputer, motor (2) by with screw rod (3) mechanical connection, motor (2) is by control signal requirement output torque, by screw rod (3) and nut (4), motor-driven valve spool (7) being produced moves axially, carry out adjust flux thereby change water inlet (5) with the cross-sectional flow area of delivery port (6), implement fire extinguishing.
