Abstract
The utility model relates to an automatic fire extinguishing device for an airplane washroom. Compared with the prior art, the automatic fire extinguishing device overcomes the defect that automatic monitoring for small-range fire extinguishing in an airplane washroom cannot be implemented. The automatic fire extinguishing device comprises a tank body (1), a valve core (4), a single-chip microprocessor (6), a temperature detector (8) and a program-controlled valve (7), wherein the valve core (4) is arranged on the upper part of the tank body (1) and is provided with a pressure gauge (2) through an O-shaped ring (3); the lower part of the tank body (1) is provided with a spray pipe (5); the program-controlled valve (7) is arranged in the spray pipe (5); the single-chip microprocessor (6) and the temperature detector (8) are arranged on the outer wall of the spray pipe (5); the temperature detector (8) and the program-controlled valve (7) are connected with the single-chip microprocessor (6) respectively. According to the automatic fire extinguishing device, when a fire breaks out in the airplane washroom, the fire can be immediately extinguished without any adverse effect on parts, except for a specified position, in the washroom.
Description
Technical field
The utility model relates to the fire-fighting equipment technical field, is a kind of automatic fire extinguisher for the aircraft washroom specifically.
Background technology
The present generation aircraft washroom is due to the standing crew of nothing, and this regional fire alarm becomes an important component part of fire alarm system, is equipped with the rigid requirement that fire extinguisher has become flight safety.And the aircraft washroom easily becomes unheeded zone on aircraft, be difficult to again be found by people at condition of a fire early period of origination.Simultaneously due to condition restriction, in the aircraft washroom, again the building fire extinguishing system can't be installed, particularly the building fire extinguishing system is large-area fire extinguishing water, can't effectively put out a fire at the condition of a fire initial stage, large-area fire extinguishing water also can cause the fault on aircraft, thereby affects the flight safety of aircraft.How to develop a kind ofly can become urgent problem for automatic fire extinguisher among a small circle.
The utility model content
The purpose of this utility model is in the aircraft washroom, can't automatically monitor the defect of putting out a fire among a small circle in order to solve in prior art, provides a kind of automatic fire extinguisher for the aircraft washroom to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of automatic fire extinguisher for the aircraft washroom, comprise tank body and the valve inside that is contained in tank body top, on valve inside, by O type circle, Pressure gauge is installed, tank body lower part is installed with jet pipe, also comprise single-chip microcomputer, hygrosensor and be arranged on the sequencing valve in jet pipe, described single-chip microcomputer and hygrosensor are arranged on the outer wall of jet pipe, and described hygrosensor is connected with single-chip microcomputer respectively with sequencing valve.
The input of described sequencing valve is connected with the output of single-chip microcomputer, and the output of described hygrosensor is connected with the input of single-chip microcomputer.
Also comprise aircraft power supply, described aircraft power supply is connected with sequencing valve, hygrosensor and single-chip microcomputer respectively.
Beneficial effect
A kind of automatic fire extinguisher for the aircraft washroom of the present utility model, put out a fire in the time of compared with prior art can be on fire in the aircraft washroom in time, and fire extinguishing can not cause any adverse effect to the position except assigned address in washroom.Effectively prevent the generation of aircraft washing inside fire, guaranteed that in the aircraft washroom, other electronic devices and components are not damaged, guaranteed the flight safety of aircraft.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is circuit block syndeton schematic diagram in the utility model
Wherein, 1-tank body, 2-Pressure gauge, 3-O type circle, 4-valve inside, 5-jet pipe, 6-single-chip microcomputer, 7-sequencing valve, 8-hygrosensor, 9-fixed strip, 10-aircraft power supply.
The specific embodiment
For making that architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1, a kind of automatic fire extinguisher for the aircraft washroom described in the utility model, comprise tank body 1 and the valve inside 4 that is contained in tank body 1 top, on valve inside 4, by O type circle 3, Pressure gauge 2 is installed, tank body 1 bottom is installed with jet pipe 5, more than the extinguishing device with pressure for using in prior art.Pressure gauge is for showing the pressure in tank body, and it is better that the O type encloses sealing effectiveness, and valve inside 4 is filled for the fire extinguishing material in tank body, and tank body 1 is arranged on the fire extinguishing zone that needs emphasis to take precautions against by fixed strip 9.Also comprise single-chip microcomputer 6, hygrosensor 8 and be arranged on the sequencing valve 7 in jet pipe 5, sequencing valve 7 is be used to controlling the switching of jet pipe 5.Described single-chip microcomputer 6 and hygrosensor 8 are arranged on the outer wall of jet pipe 5.As shown in Figure 2, hygrosensor 8 is connected with single-chip microcomputer 6 respectively with sequencing valve 7, the input of described sequencing valve 7 is connected with the output of single-chip microcomputer 6, the output of described hygrosensor 8 is connected with the input of single-chip microcomputer 6, aircraft power supply 10 is connected with sequencing valve 7, hygrosensor 8 and single-chip microcomputer 6 respectively, and the airborne power supply of aircraft provides the power supply supply for whole monitoring and control equipment.
During actual the use, single-chip microcomputer 6 is carried out to the setting of temperature value, when the temperature of hygrosensor 8 detection aircraft washrooms surpasses setting value, hygrosensor 8 is to single-chip microcomputer 6 output fire signals, and single-chip microcomputer 6 is controlled sequencing valve 7 and opened, and the extinguishing chemical in tank body is under the effect of pressure, from jet pipe 5, spraying extinguish material to reach the effect stamped out a fire rapidly, due to the restriction of jet pipe 5 positions, can be arranged on the top, zonule of the easy discovery condition of a fire simultaneously, reach the effect of putting out a fire among a small circle.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
