Detailed description of the invention

Fig. 1 is the backside structure figure in the utility model embodiment for the automatic fire extinguisher of electrical cabinet.

Fig. 2 is the structural schematic diagram of automatic fire extinguisher in the utility model embodiment.

The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.

Specific embodiment

The technical solution of the utility model is described in detail below with reference to drawings and the specific embodiments, to become apparent from, directly See the invention essence that ground understands the utility model.

Shown in referring to Fig.1, the present embodiment provides a kind of automatic fire extinguisher 100 for electrical cabinet, which includes Cabinet body 10 and automatic fire extinguisher 20, the cabinet body 10 includes multiple interlayers 101 from lower and lower arrangement, and is provided with front door 102 and back door 103, user, which opens front door 102, can install electrical equipment and wiring etc., and opening back door 103 can check and more Change automatic fire extinguisher 20.

Referring to shown in Fig. 2, the automatic fire extinguisher 20 of the present embodiment is fixedly installed in an interlayer 101 positioned at top layer It is interior, it is provided at least waypoint domain fire extinguishing channel 210 and at least road surface domain fire extinguishing channel 220.Described domain fire extinguishing channel 210 are laid with downwards by the hose 211 of a warm mutagens, and one end of the hose 211 is connect with the automatic fire extinguisher 20, To obtain pressurized fire suppressant, other end closing.The face domain fire extinguishing channel 220 is laid with downwards by a copper pipe 221, the copper pipe 221 one end is connect with the automatic fire extinguisher 20, and to obtain pressurized fire suppressant, the other end connects a glass tube 222, described Temperature sensing liquid is sealed in glass tube 222.The hose 211 is suitable for softening under specific temperature conditions, makes in the hose 211 Pressurized fire suppressant broken wall and go out.The glass tube 222 is suitable for rupturing and being discharged in the copper pipe 221 under specific temperature conditions Pressurized fire suppressant, to realize self-extinguishing.

Specifically, the hose 211 wriggles and is laid with along the side of the partition of the cabinet body 10 and the side wall of interlayer 101, with Just it can put out a fire to each interlayer 101, principle is the known materials that the hose 211 is 160 ± 30 DEG C by denaturation temperature It is made, the pressure of the pressurized fire suppressant is 1.0 ± 0.2MPa.When the temperature of the region point where hose 211 reaches 130~ At 190 DEG C, hose 211 softens, and pressurized extinguishing chemical is broken through, and extinguishing chemical sprays, to realize extinguishing action.

On the other hand, the copper pipe 221 is laid with downwards along the side wall of the interlayer 101, and the material of the copper pipe 221 is Red copper, the temperature that the glass tube 222 ruptures are 90 ± 30 DEG C.When the temperature of 222 peripheral region of glass tube reaches 90~120 DEG C When, the temperature sensing liquid expanded by heating in glass tube 222, until glass tube 222 is burst, glass tube 222 is broken fall after, push against simultaneously The piston pressurized extinguishing chemical (not shown) for sealing copper pipe 221 squeezes out, and extinguishing chemical is sprayed from copper pipe, to realize that fire extinguishing is dynamic Make.

Therefore, point domain fire extinguishing channel 210 and face domain fire extinguishing channel 220 can be handled fire hazard in time.

Preferred mode is that above-mentioned automatic fire extinguisher 20 is detachably secured in the interlayer 101, in order to certainly When extinguishing chemical inside dynamic extinguishing device 20 is reduced, it is convenient to fill extinguishing chemical, or when automatic fire extinguisher 20 is damaged When, replaceable automatic fire extinguisher 20, without replacing entire electrical cabinet 100, to save cost.

In the present embodiment, the extinguishing chemical can be gas or aerosol, it is to be understood that in other embodiments, It is not excluded for using the liquid extinguisher that can be used for electrical fires fire extinguishing.

Above-mentioned automatic fire extinguisher 20 is also equipped with a manual switch 230, to control described domain fire extinguishing channel 210 and face The opening and closing in domain fire extinguishing channel 220.For example, during transportation, the manual switch 230 can be closed, in self-extinguishing After device 20 and electric wiring are laid, the manual switch 230 can be opened, to improve safety.

The automatic fire extinguisher is additionally provided with an alarm module 240, and the alarm module 240 is suitable for going out in described domain After fiery channel 210 and/or face domain fire extinguishing channel 220 are put out a fire, an alarm signal is exported, alternatively, automatic fire extinguisher is additionally provided with Pressure gauge 250.Adoptable mode is, for example, which arrives monitoring room by connection, when generation fire or Person is after described domain fire extinguishing channel 210 and/or face domain fire extinguishing channel 220 are put out a fire or pressure gauge 250 detects internal firefighting When the pressure value of agent is less than threshold value, automatic fire extinguisher 20 exports an alarm signal, passes through the line transmission to monitoring room, security personnel Personnel or system security official can grasp fire dangerous situation in time, to make appropriate processing in time.

In conclusion the utility model can be examined accurately using point domain fire extinguishing channel and face domain fire extinguishing channel binary channels fire extinguishing Extinguishing chemical can be released immediately when a fire by surveying environment temperature, with it is timely, automatic, effectively put out a fire, to be sent out in fire Raw initial stage can detect in time and can effectively put out, and to prevent trouble before it happens, reduce loss, effective guarantee to the maximum extent Personnel and property safety using unit.

The above is only the preferred embodiment of the present invention, is not intended to limit its scope of the patents, all to utilize this Equivalent structure transformation made by utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks Domain is also included in the patent protection scope of the utility model.
