Description
Technical field
The utility model relates to low-tension distribution box vacuum fire extinguishing field, specially a kind of low pressure with automatic fire-extinguishing function
Distribution box.
Background technique
Low-tension distribution box is useful in each plant area and market, although low-voltage distribution cabinet voltage is relatively low, have
A little place electricity consumptions are big, such as market, especially in summer, it is easy to and it causes distribution box temperature excessively high and catches fire, therefore, fire prevention
It is critically important, occur various fire extinguishing distribution boxs in the market, add fire extinguisher, still, these structures are more complicated, fire extinguishing
Device is added up, it is not intended to considerably increase cost, therefore, it is necessary to a kind of at low cost convenient for universal fire extinguishing low-tension distribution box.
Utility model content
The purpose of this utility model is to provide a kind of low-tension distribution boxes with automatic fire-extinguishing function, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of low pressure with automatic fire-extinguishing function
Distribution box including cabinet and is hingedly connected to the chamber door of cabinet front end, be separately installed in the cabinet smoke sensor device with
And it is electrically connected the controller of smoke sensor device；
The upper end of the cabinet offers air inlet, and the pumping being electrically connected with controller is connected on the downside of the outer end of cabinet
Blower, be equipped on the cabinet when smoke sensor device detects smog to air inlet carry out closing promote in cabinet air every
Exhausted mechanism of dying.
Preferably, the mechanism of dying includes the solenoid valve being connected on air inlet, and the controller is electrically connected electromagnetism
Valve.
Preferably, the inlet end of the solenoid valve is provided with filter screen.
Preferably, be provided on the upside of the inner cavity of the cabinet by the air dispersion that air inlet enters blow to case it is intracorporal every
Plate, and air-permeating hole is uniformly provided on partition.
Preferably, the junction of the chamber door and cabinet is provided with gasket.
Compared with prior art, the utility model has the beneficial effects that
1, exhaust fan works, and pressure reduces in cabinet, and air enters through solenoid valve from air inlet, under the action of partition,
Air is located at the chamber on the upside of partition full of cabinet, to uniformly be blowed in cabinet downwards along air-permeating hole, to internal components into
Row cooling, heat is extracted out through exhaust fan again, to guarantee that internal temperature is not too high, it is not easy to catch fire；
2, it when box house catches fire, can be detected by smoke sensor device, signal is transmitted to controller, controller control
Electromagnetic valve work is closed, and such cabinet forms airtight chamber, and air constantly reduces, and has lacked oxygen, fire source will be slowly
Extinguish, to put out a fire；
Here, increasing solenoid valve on the basis of cooling, carry out vacuum fire extinguishing, cooling intelligent fire fighting has, relative to
Fire extinguisher in the market, cost is lower, convenient for universal, and, it is not easy to the interior of cabinet is made dirty because fire extinguishing generates spray
Portion's device does not generate any fire extinguishing raw material, more environmentally friendly health here.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the main view of the utility model.
In figure: 1 cabinet, 11 smoke sensor devices, 12 controllers, 2 air inlets, 21 exhaust fans, 22 solenoid valves, 23 filter screens,
24 partitions, 25 air-permeating holes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1 to 2 is please referred to, the utility model provides a kind of low-tension distribution box technical solution with automatic fire-extinguishing function:
A kind of low-tension distribution box with automatic fire-extinguishing function including cabinet 1 and is hingedly connected to the chamber door of 1 front end of cabinet, cabinet 1
It is inside separately installed with smoke sensor device 11 and is electrically connected the controller 12 of smoke sensor device 11, smoke sensor device 11 connects here
Controller 12 is connect, control fire extinguishing component actuation can all go out in the fire extinguishing system in each mansion market for technology common in the market
Existing, therefore, specific connection and model are no longer described in detail, for example controller 12 can use 80C51.
The upper end of cabinet 1 offers air inlet 2, and is connected on the downside of the outer end of cabinet 1 and the electric connection of controller 12
Exhaust fan 21 is equipped on cabinet 1 and carries out closing to air inlet 2 when smoke sensor device 11 detects smog and promote in cabinet 1
The mechanism of dying of air exclusion, mechanism of dying include the solenoid valve 22 being connected on air inlet 2, and controller 12 is electrically connected electromagnetism
Valve 22, solenoid valve 22 work, and 1 air of cabinet is promoted to cannot be introduced into, and working on for exhaust fan 21, promote air in cabinet 1
