Description
Technical field
The utility model relates to a kind of fire-extinguishing apparatus, especially a kind of fire hydrant product.
Background technology
As everyone knows, indoor fireplug is the fire-extinguishing apparatus of pipe network in house to delivery of water, and generally, fire hydrant is arranged on eye-catching, visibility point in building, and the obvious sign marking should be arranged, and is easy to people and finds and use.But in actual use, a lot of fire hydrants are arranged in the corner of building, and show to lack the eye-catching sign marking, when breaking out of fire, people are difficult to find the position of fire hydrant, have therefore incured loss through delay fire extinguishing and have easily caused casualties opportunity.
Summary of the invention
The utility model purpose be to provide a kind of safe and reliable, easy and simple to handle, easy to use, be convenient to the position of hydrant suggestion device of finding.
For achieving the above object, the utility model has adopted following technical scheme: comprise shell, sparge pipe and dodge gate, described shell is the vertical cabinet structure, and dodge gate is offered in front, inner installation sparge pipe, and sparge pipe and water inlet pipe connection; Smoke Sensor and luminance sensor are installed in top at shell; Inner edge in the active side of dodge gate is installed iron plate, and electromagnet is installed in corresponding dodge gate iron plate position in the enclosure, electromagnet and iron plate adhesive, and described electromagnet is connected respectively with manual key switch with Smoke Sensor; Lay LED lamp group at the outer surface of dodge gate, described LED lamp group is connected respectively with Smoke Sensor with luminance sensor.
Ceiling light is installed in the enclosure, and described ceiling light and manual switch connect to form lighting circuit.
Daytime, while using,, because ambient light is stronger, luminance sensor was judged as daytime, the output high level, and corresponding relay receives high level signal, and relay is not opened, and corresponding prompting LED lamp does not work.When dodge gate is closed, press manual key switch and just can open the door, corresponding relay receives low voltage signal, disconnects electromagnet power supply, and now, door automatically springs open.When breaking out of fire, Smoke Sensor detects smog, when smokescope surpasses threshold value, and the output LOW voltage signal, corresponding relay receives low voltage signal, and electromagnet cuts off the power supply, LED lamp group is luminous, and now dodge gate is opened automatically.
Night, while using,, because ambient light is darker, luminance sensor was judged as night, output low level, and corresponding relay receives low level signal, and relay is opened, and corresponding prompting LED lamp group is luminous, and the prompting people are fire-fighting equipment herein.Other functions are identical during with daytime.
In addition, after the user opens dodge gate, also can open ceiling light by manual switch, illuminate enclosure, be convenient to the user and look for the fire-fighting equipments such as sparge pipe.
As shown from the above technical solution, the utility model has the advantages that: reasonable in design, convenient and practical, simple to operate, safe and reliable, possess eye-catching prompt facility, be convenient to people and find fire-fighting equipment, and can automatically open dodge gate, for people's fire-fighting equipment of taking facilitates.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Drawing reference numeral in figure: 1 is that shell, 2 is that sparge pipe, 3 is that dodge gate, 4 is that Smoke Sensor, 5 is that luminance sensor, 6 is that iron plate, 7 is that electromagnet, 8 is that LED lamp group, 9 is that ceiling light, 10 is manual switch.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In perspective view of the present utility model as shown in Figure 1, the utility model comprises shell 1, sparge pipe 2 and dodge gate 3, and described shell is the vertical cabinet structure, and dodge gate is offered in front, inner installation sparge pipe, and sparge pipe and water inlet pipe connection; Smoke Sensor 4 and luminance sensor 5 are installed in top at shell; Inner edge in the active side of dodge gate is installed iron plate 6, and electromagnet 7 is installed in corresponding dodge gate iron plate position in the enclosure, electromagnet and iron plate adhesive, and described electromagnet is connected respectively with manual key switch with Smoke Sensor; Lay LED lamp group 8 at the outer surface of dodge gate, described LED lamp group is connected respectively with Smoke Sensor with luminance sensor.
Ceiling light 9 is installed in the enclosure, and described ceiling light and manual switch 10 connect to form lighting circuit.
Below further describe the principle and the function that respectively form device:
1, Smoke Sensor: adopt the MQ-2 sensor as Smoke Sensor, integrated voltage comparator LM393 on circuit board, making output signal is analog signal and data signal (threshold value is by the potentiometer adjustment), adopt data signal in this device, when there is no smog or smokescope less (not breaking out of fire), output voltage is 5V, and when smog surpasses setting threshold concentration (having fire to occur), output voltage is 0V.
2, luminance sensor: adopt photo resistance as luminance sensor, while using voltage comparator LM393 as signal processing circuit, the analog quantity of photo resistance output changes into digital quantity.Use two substitutional resistances dividing potential drop of being connected at the end of oppisite phase of voltage comparator LM393, making its voltage is 2.5V, and this voltage is as threshold voltage.During daytime, photo resistance resistance is low, and the voltage ratio threshold voltage that the divider resistance of series connection with it divides is high, comparator output high level; During evening, photo resistance resistance is high, and the voltage ratio threshold voltage that the divider resistance of series connection with it divides is low, comparator output low level, thereby judgement daytime and evening.
3, LED lamp group: use warning light (night bright) and the illuminating lamp (device for opening bright) of 7 LED series connection (band current-limiting resistance) as device, by the break-make of power source for relay control.
4, electromagnet: use the opening switch of P30/22 direct current sucked type electromagnet as dodge gate, electromagnet suction 10kg, supply voltage 12v, by Control, when pressing manual key switch or get angry calamity, the electromagnet outage, dodge gate is opened automatically, energising under normal circumstances, dodge gate is closed.
5, control relay circuit: control relay circuit is formed and is furnished with the LED light of response by optocoupler, triode, relay, and optocoupler plays the effect of signal isolation, and triode increases the driving force of signal, and input signal is for effectively low.
6, power module: system as power supply, is used rechargeable battery as stand-by power supply by the 220V alternating current.The 220V alternating current becomes the 24V direct current after switch power module, uses L7805 and LM2575-ADJ as the lowering and stabilizing blood pressure chip, exports respectively 5V and 12V voltage, gives other module for power supply.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
