Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to a fire extinguisher device used indoors. Background Art

[0002] In high-rise residential areas, many fires are caused by natural gas leaks. Therefore, some residents now install gas leak alarms and fire alarms in places such as kitchens where gas leaks are most likely to occur, to remind users to extinguish the fire as soon as possible when gas leaks and fires occur.

[0003] Although the alarm can give an alarm prompt at the first time of fire and gas leakage, its shortcomings are also obvious. Specifically, if the user is not at the scene when gas leakage and fire occur and the alarm sounds, the accident will be aggravated. Moreover, when gas leakage and fire occur, the user may be poisoned by gas and burned by fire due to lack of experience. In summary, it is particularly necessary to provide a fire extinguisher device that can spray water to extinguish fire, dilute the gas concentration in the air, and turn off the main gas valve and main power switch in the first time when gas leakage and fire occur, reduce the probability of accident aggravation, and can promptly wirelessly prompt the community property management to handle the situation.

The lower end of the movable column of the electric push rod M is sealed and welded to the upper inner part of the connecting pipe 42, and a bearing 48 is tightly sealed and sleeved on the inner lower end of the connecting pipe 43. A sealing ring is installed between the upper and lower ends of the inner and outer rings of the bearing 48. A water inlet pipe 43 is horizontally welded to the middle of the left outer side of the connecting pipe 43. The left end of the water inlet pipe 43 is threadedly connected to one end of the solenoid valve DC, and the other end of the solenoid valve DC is connected to the tap water pipe through a hose; the left and right side ends of the fire extinguishing pipe 41 are closed structures, and a water inlet pipe 43 is welded to the middle of the upper left end of the fire extinguishing pipe 41.

The lower end of the fire extinguishing pipe 41 is provided with a plurality of water spray holes 45 spaced from left to right, and there is an opening 46 on the front side of the right end of the fire extinguishing pipe. A fixing plate 47 is welded to the upper end of the cylinder of the electric push rod M, and the fixing plate 47 is bolted to the indoor ceiling such as the kitchen. The ceiling has an open groove (not shown) with a length slightly larger than the horizontal length of the fire extinguishing pipe, and the fire extinguishing pipe 41 is located in the open groove; one end of the solenoid valve ADC1 is threadedly connected to the indoor natural gas pipe, and the other end of the solenoid valve ADC1 is connected to one end of the natural gas manual valve (not shown) through a pipe joint, and the other end of the manual valve is threadedly connected to the main natural gas pipe (not shown) in the home. The power module W1, the detection circuit 1, and the control circuit 2 are installed in the component box 5, which is installed on the wall of the kitchen, etc. The alarm B is installed in the electric control box 6 on the ground floor of the unit building (the electric control box is installed in the public corridor at the outer end of the first floor of the unit building). The alarms of multiple households in the unit building are installed together in the electric control box.

[0016] Figure 1 , 2As shown in , the solenoid valve DC is a normally closed valve core solenoid valve, and the solenoid valve ADC1 is a normally open valve core solenoid valve. The detection circuit includes a fire detection module W and a gas leak detection module W2, diodes VD1 and VD2, and a relay K1 connected via circuit board wiring. The control power input terminal of the relay K1 is connected to the positive power input terminal 1 of the fire detection module W and the gas leak detection module W2, the negative power input terminal 2 of the fire detection module W and the gas leak detection module W2 is connected to the negative power input terminal of the relay K1, the output terminal 3 of the fire detection module W and the gas leak detection module W2 is connected to the positive poles of the two diodes VD1 and VD2 respectively, and the negative poles of the two diodes VD1 and VD2 are connected to the positive power input terminal of the relay K1. The control circuit includes a time-controlled switch W3 and a relay K2 connected via circuit board wiring. The positive power input terminal 1 of the time-controlled switch W3 is connected to the positive power input terminal of the relay K2, and the negative power input terminal 2 of the time-controlled switch W3 is connected to the negative power input terminal of the relay K2. The present invention has multiple sets, and the number is consistent with the number of residents in the unit building. The alarm B is an alarm sound and light alarm. The power input end of each sound and light alarm B and the power output end relay K1 of the detection circuit are connected by wires. The front side end of the sound and light alarm B of the multiple receiving circuits is located at the front outer side of the electric control box, and the electric control box on the side of each sound and light alarm B is marked with a number representing the corresponding household number of the unit building. The power input end 1 and 2 pins of the power module W1 are connected to the two poles of the AC 220V power supply by wires, the power output end 3 and 4 pins of the power module W1 are connected to the power input end relay K1 of the detection circuit and the negative power input end by wires, and the power output end relay K1 of the detection circuit and the normal open contact end and the negative power input end are connected to the 1 and 2 pins of the power input end time switch W3 of the control circuit by wires. The 3 and 4 pins of the time switch W3 are connected to the positive and negative power input ends of the electric push rod M by wires. The normally open contact terminal and the negative power input terminal of the relay K1 are connected to the power input terminals of the solenoid valve DC and the solenoid valve ADC1 through wires. The control contact terminal and the normally open contact terminal of the relay K2 are connected to the two contacts under the opening test button SY of the air switch at home through wires.

[0017] Figure 1 , 2As shown, the new fire extinguishing pipe 41 is usually located in the open slot, which does not affect the aesthetics of the kitchen, etc. After the AC power enters the power input terminal of the power module W1, the 3 and 4 pins of the power module W1 output a stable DC 12V power supply to enter the power input terminal of the detection circuit. When there is no fire on the scene, the 3 pin of the fire detection module W (the detection surface is located outside the first opening at the front end of the component box) does not output a high level, so the relay K1 will not be powered on and the control circuit will not be powered on; when a fire occurs on the scene, the 3 pin of the fire detection module W outputs a high level through the diode VD1 unidirectional conduction into the positive power input terminal of the relay K1, then the relay K1 will be powered on and its control power input terminal and the normally open contact terminal will be closed, and then the control circuit will be powered on and work. After the gas leak detection module W2 (the detection surface is located outside the second opening at the front end of the component box) is powered on, when there is no gas leak on site, the 3rd pin of the gas leak detection module W2 does not output a high level, then the relay K1 will not be powered on and the control circuit will not be powered on; when a gas leak occurs on site, the 3rd pin of the gas leak detection module W2 outputs a high level and enters the positive power input terminal of the relay K1 through a diode VD2 in a unidirectional manner, then the relay K1 will be powered on and its control power input terminal and normally open contact terminal will be closed, and then the control circuit will be powered on and work. After the control circuit is powered on, the relay K2 will be powered on and its control contact terminal and normally open contact terminal will be closed, so that the two contacts under the tripping test button SY of the air switch in the home will be closed, and then the air switch will trip, preventing the electrical equipment from being powered off during fires (including electrical fires), leading to the expansion of accidents. After the time switch W3 is energized, its 3rd and 4th pins will output 6 seconds of power to the positive and negative power input terminals of the electric push rod M. The movable column of the electric push rod M will push the fire extinguishing pipe 41 downward to prepare for water spraying fire extinguishing (the fire extinguishing pipe 41 is located outside the lower end of the opening slot). After the solenoid valve DC is energized, the valve core opens, and tap water enters through the left end of the connecting pipe 42, and then sprays downward through the multiple water spray holes 45 at the lower end of the fire extinguishing pipe 41 to extinguish the kitchen and other related areas (fire-prone points, such as the upper end of the stove). At the same time, pressurized water is sprayed from the front opening 46 at the right end of the fire extinguishing pipe to generate reverse thrust, pushing the left end of the fire extinguishing pipe 41 to rotate along the bearing, and the fire extinguishing pipe rotates to extinguish the fire in the relevant area (and can dilute the leaked natural gas), which can achieve a better fire extinguishing coverage effect. After the solenoid valve ADC1 is energized, its valve core is closed, so that natural gas no longer enters the stove, etc., preventing the gas from being ignited during a fire and causing the accident to expand. In the event of a fire or gas leak on site, during the time when relay K2 is energized and its control power input terminal and normally open contact terminal are closed, alarm B will be energized to emit an audible and visual alarm signal.

[0018] Figure 1 , 2As shown above, the new type outputs a signal to the control circuit when a fire or gas leakage occurs in the corresponding area of ​​the home. The control circuit can promptly shut off the main power switch of the gas valve in the home and the electrical equipment in the home, and can automatically spray water, automatically extinguish the fire and dilute the leaked combustible gas by rotating the fire extinguishing pipe. The fire signal can also be transmitted to the electric control box on the ground floor of the residential unit. The sound and light alarm in the electric control box sends out a sound and light alarm signal. The community property management personnel (or other people passing by in the community) can understand the specific situation in a relatively short time, go to the relevant residential homes to assist in fire extinguishing, etc., reducing the probability of gas leakage and fire accidents expanding. The diodes VD1 and VD2 are of model 1N4007 (unidirectional conduction); the relays K1 and K2 are of model DC12V; the power module W1 is a power module for converting AC 220V to DC 12V; the time switch W3 is a microcomputer time switch product of model KG316T, which has two power input terminals, two power output terminals, and seven setting buttons, and the time for the two power output terminals to output power can be set by operating the seven buttons respectively; the alarm B is a sound and light alarm product of model ED-1081J; the fire detection module W is a smoke fire alarm product of model JTY-GD-930, which has two power input terminals and one signal output terminal. When a fire is detected, the signal output terminal can output power, otherwise it will not output; the gas leak detection module W2 is a combustible gas leak detection module product of model MQ-4, which has two power input terminals and one signal output terminal. When a gas leak is detected, the signal output terminal can output power, otherwise it will not output; the electric push rod M is a reciprocating electric telescopic rod product with a power of 30W.
