FIRE EXTINGUISHER BASED ON UPPER COVER [0002]

The present invention relates to an upper cover for an extinguishing apparatus and an upper cover-based extinguishing apparatus. More specifically, the present invention relates to an upper cover for an extinguishing apparatus for protecting a fire extinguishing liquid container from an external force, And an upper cover-based fire extinguishing system.

A fire extinguisher is a device used in advance inside a building or at a suitable place in a vehicle and used to turn off the fire immediately after a fire occurs. Fractional fire extinguishers that use compressed air as a cylinder made of metal, carbon dioxide gas fire extinguishers that generate chemically generated carbon dioxide gas, powder fire extinguishers that blow out soda ash powder, and foam fire extinguishers that breathe carbon dioxide gas.

Conventionally, these fire extinguishers are installed in advance at appropriate places or entrance of the passageways, allowing many people to know their installation places, and can quickly evolve using fire extinguishers under an emergency called fire occurrence.

In other words, in most fire extinguishers, when a fire extinguisher is to be used, the safety pin, which is a part of the fire extinguisher, is pulled out and the lever is pulled to release the discharged fire extinguisher.

In this fire extinguisher, when the filled nitrogen is used as the extinguishing material, the pressure is 52.7㎏ / ㎠, and instantaneous injection is performed by using high pressure. Accordingly, the fire extinguishing material container must have a strength that can be protected by external force against internal and external pressures.

The container fastening end 132 is formed to have a cylindrical shape of which the upper and lower ends are cut to have a short height and to be fixed while enclosing the upper outer surface of the main container 140. To this end, the upper portion of the main body container 140 is formed in a conical shape and overlapped with the lower surface of the cover main body 131, and the lower end region thereof is surrounded by the container fastening end 132.

The concave curved surface 133 is an area where the concave curved surface 133 is in contact with the rear surface of the jetting end 160. A jetting passage groove 135 is formed in the upper end of the front central region, 134 and the jet hole passing groove 135 are formed.

The gauge insertion groove 134 is inserted into the detection end of the pressure gauge 130a and the ejection hole passing groove 135 provides a structure in which the ejection port of the lower lever connection end 180a having the ejection opening is fastened from the upper portion to the lower portion, The connection end fixing ring insertion groove 136 provides a structure in which the fixing ring of the lower lever connection end 180a with the ejection opening is fastened from the upper part to the lower part.

On the other hand, the remaining half of the gage insertion groove 134 and the coupling end fixing groove insertion groove 136 formed in the coupling surface 133 described above is formed in the supporting curved surface 137. More specifically, the gage insertion groove 134 and the coupling end fixing groove insertion groove 136 have a structure extending in the direction of the supporting curved surface 137 with respect to a half formed on the coupling curved surface 133.

That is, the supporting curved surface 137 is formed with a larger diameter than the connecting curved surface 133, and constitutes one half of the body of the multiple connecting means aggregate 130a.

In this structure, the upper cover 130 is separated from the main body container 140, and a region through which the introduction pipe fixing body 195 passes can be formed at the center.

Here, the introduction pipe fixing body 195 is inserted into the center hole of the upper cover 130, and the introduction pipe is inserted and fixed through the lower end.

The upper end of the inlet pipe fixing member 195 and the upper lever 170 are connected to each other by a lower lever connecting end 180a. The upper end of the upper cover 130 abuts against the lower lever 180 at an upper portion of the lower lever connecting end 180a having a jet port. And has a structure in which a jetting end connecting portion 160 is connected.

The main body container 140 has a cylindrical shape and contains a digestive substance such as an accumulative extinguishing powder, an extinguishing liquid, a fire extinguishing gas, and the like. The upper surface of the main body container 140 is hemispherical to be superimposed on the lower surface of the upper cover 130, A container holder 140a for protecting from an external force can be provided.

The trumpet-type spraying unit 150 allows the extinguishing material to be radially sprayed in a conical shape in which the upper and lower ends are cut in place of the conventional fire hose.

As described above, the blowing-out connecting end 160 is formed to surround the front of the upper cover 130 and has a hole through which the blowing-out port can pass. Thus, the blowing-out connecting end 160 is coupled to the blowing- It provides a structure that can be.

Through this structure, the extinguishing material is moved upward by the vertical pressure generated by the provision of the external force to the upper lever 170 and the lower lever 180 through the introduction pipe, and then the trumpet- Lt; / RTI >

Meanwhile, the pressure gauge 130a is formed in a region where the spraying end connecting portion 160 is in contact with the upper cover 130 in the horizontal direction, and the pressure of the extinguishing material passing through the inlet pipe fixing body 195 therein is measured can do. Here, the pressure gauge 130a may be formed of an analog pressure gauge or a digital pressure gauge.

In the upper cover-based fire extinguishing system 100 designed with such a structure, the tensile strength, the tear strength and the tear strength of the upper cover 130 and the upper and lower ends of the upper cover-based fire extinguishing apparatus 100, 12 (a) to 12 (c), all of which are improved as compared with those before the mounting of the upper cover 130.

The TAPPI T 404 om-87 and TAPPI T 511 om-83 were used for tensile strength and tensile strength, respectively. The TAPPI T 451 cm-84 was used for the TAPPI T 451 cm-84 and the Clark type was used for the stiffness. The tear strength was measured using the Mullen low-pressure tester according to TAPPI T 403 om-85.

The upper cover-based fire extinguishing system 100 is configured such that the safety bar 110 is detachable and includes an upper lever 170, a lower lever 180, a trumpet-type spraying unit 150, a jetting- And the upper cover 130 can be separated from each other. The main container 140 is refilled by separating the upper cover 130 after removing the upper lever 170, the lower lever 180, the trumpet-type spraying unit 150, ) Can be provided.

The airtightness of the upper cover 130 in the upper cover-based fire extinguishing system 100, that is, the generation of particles due to adhesion of the upper cover 130 to the space between the inlet pipe fixing body 195 and the main body container 140 The relationship with the suppression was found to be the result of the parameter setting of the main container 140 as shown in [Table 1] below. Here, the hermeticity was measured by an external waterproof test. The relation with the particle generation suppression is that the fire extinguishing material is sprayed to the upper cover 130 and the particulate matter collecting device to suppress particle generation in the state that the upper cover 130 is attached to the fire extinguishing apparatus 100 based on the seal sticker , Performance was tested based on whether or not 15 ppm or more of particulates were generated per square meter, and if it is less than 15 ppm, it is judged to be suitable for particulate test.
