Description

Fire Extinguisher Bomb With Curved Shape At Both Ends

The present invention relates to a digestion gun having curved ends formed at both ends in a curved shape. More particularly, the present invention relates to a fire extinguisher which is fire extinguished in a fire scene, maintains a posture for efficiently extinguishing the fire extinguishing agent, and is capable of detecting the heat of fire and ejecting the fire extinguishing agent. .

A fire extinguisher is a device that injects fire extinguishing agents into the inside of the fire and extinguishes the fire. Fire extinguishers are being developed in various ways so as to be able to effectively extinguish the fire according to various causes of fire accidents. For example, fire extinguishers are being developed as foam fire extinguishers useful for gasoline and chemical fires, powder fire extinguishers useful for electric fires, and halon fire extinguishers useful for gas fires.

Such a fire extinguisher is a structure in which the user has to operate directly at a fire site. Therefore, the user is burned in the process of operating the fire extinguisher at the fire scene, or sucking the toxic gas and suffocating.

Currently, fire extinguishers are being developed to prevent the occurrence of such accidents so that the user can suppress the fire without approaching the fire scene. For example, fire extinguishers have been developed to thrash fire by throwing them at a fire scene. Such throwing fire extinguishers are disclosed in Korean Utility Model Registration No. 20-0184406.

However, most of the developed fire extinguishers have problems that the spray nozzles are clogged on the floor when they are thrown and the fire extinguishing agent can not be sprayed properly and thus the fire can not be effectively suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, components of a fire extinguisher having curved ends at both ends according to an embodiment of the present invention will be described in detail.

The enclosure 100 is formed in a cylindrical body having a receiving space 110 formed therein and a curved surface 140 having an injection port 141 formed at one end and the other end. Such an enclosure 100 may be formed in a shape that can be readily gripped by a worker and a firefighter, or a shape that can be easily mounted on an unmanned airplane.

 The gas container unit 120, the motor unit 130 and the inner container unit 150 are installed in the housing space 100 of the enclosure unit 100. A part of the outer surface of the enclosure unit 100 is exposed to the outside A fire detection sensor unit 160 for detecting a fire is installed. The injection port 141 of the curved surface 140 is provided with an injection nozzle 142 for injecting the extinguishing agent into the inside of the enclosure 100.

In addition, the enclosure 100 includes a gas injection tube 144, a fire extinguishing agent injection tube 143, and the like.

The gas container unit 120 is a container filled with a high-pressure gas therein. Here, the gas may be nitrogen or carbon dioxide. The gas container unit 120 has a structure in which one end communicates with the other end of the inward portion and a structure in which one end communicates with the other end of the inside portion and a gas injection pipe 144 is installed therein. .

The gas injection tube 144 is connected at one end to the gas container part 120 and at the other end inside the internal cavity part 150 so that the high pressure gas G in the gas container part 120 is passed through the internal cavity part 150, . In particular, the gas injection pipe 144 further includes a check valve 145 for preventing backflow of the gas discharged to the outside. The backflow prevention valve 145 will be described in detail with reference to FIG.

An opening and closing part 131 is provided between the gas container part 120 and the gas injection pipe 144 to control the flow of the gas in response to the operation of the motor part 130, It is possible to control the flow of the high-pressure gas. For example, the opening / closing part 131 may be formed as a damper, and may be connected to the shaft of the motor part 130 to rotate in accordance with the amount of rotation of the shaft.

The motor unit 130 may be a motor driven by a DC voltage. The motor unit 130 may be driven by a power supplied from a fire detection sensor unit 160 or may be driven by a power supplied from a battery.

The fire detection sensor unit 160 senses heat and generates electricity to allow the voltage to be transmitted to the motor unit 130. The fire detection sensor unit 160 has a structure in which one surface is exposed on the outer surface of the enclosure and the other surface is installed in the accommodation space 110.

For example, the fire detection sensor unit 160 senses heat through one surface exposed on the outer surface of the enclosure to generate electricity, applies the generated electricity to the motor unit 130 connected to the other surface of the accommodation space 110, And drives the switch unit 190 disposed between the battery unit 130 and the battery unit B.

The motor unit 130 may be driven by a voltage applied from the fire detection sensor unit 160 or a voltage transmitted from the battery unit B. [

Furthermore, the fire detection sensor unit 160 can generate electricity only when the heat transmitted from the outer side is higher than the set temperature (the temperature higher than the normal temperature), and can not be operated at room temperature.

The inner container 150 becomes a container filled with an extinguishing agent. Here, the extinguishing agent (H) may be a sodium hydrogen carbonate powder or a monobasic ammonium phosphate powder.

One end of the inner cap 150 communicates with the injection port 141 so that the extinguishing agent H present inside the cap 150 can be discharged to the outside of the enclosure 100. One end of the extinguishing agent spray pipe 143 is connected to the spray nozzle 142 provided at the ejection port 141 and the other end is connected to the inside port 150 So that the extinguishing agent can be discharged to the outside of the enclosure 100.

The extinguishing agent spraying pipe 143 allows the extinguishing agent in the inner casing 150 to be discharged to the outside by the gas introduced into the inner casing 150 from the gas container unit 120. The shape and operation of the extinguishing agent spray tube 143 will be described in detail with reference to FIG.

In addition, the enclosure 100 includes a partition 103 dividing the accommodation space into a plurality of spaces. The partition part 103 is installed in a direction perpendicular to the longitudinal direction of the body.

For example, a partition 103 may be provided at the center of the enclosure 100 to divide the accommodation space into a first accommodation space and a second accommodation space. That is, the enclosure 100 may have a first enclosure having a first accommodating space and a second enclosure having a second accommodating space by the partitioning unit 103. [ Here, the first enclosure has a first ejection opening 141a formed in the first curved surface 140a and the first curved surface 140a, a second curved surface 140b and a second curved surface 140b in the second enclosure, And a second jet opening 141b formed therein. The first enclosure and the second enclosure may include devices installed in the accommodation space 110 formed in the one enclosure 100 described above.

The partition part 103 in the present specification is not limited to being formed as a single unit and installed in the accommodation space 110 as described above, and may be formed as a plurality as needed to divide the accommodation space into a plurality of parts.

However, in the present specification, a description will be given of an example in which the partition part 103 is formed as one so that the description of the curved digits at both ends can be concise and clear.

Hereinafter, the structure and operation of the check valve and the extinguishing agent dispensing tube will be described with reference to FIGS. 3 and 4. FIG.

The check valve 145 is provided at one end of the gas injection pipe 144 so that the gas injected from the gas injection pipe 144 is not re-introduced into the gas injection pipe 144 again. For example, the check valve 145 may be a disk check valve. The backflow prevention valve 145 closes the passage as shown in FIG. 3 (a). When the high pressure gas flows from the other side as shown in FIG. 3 (b) As shown in FIG.

When the high-pressure gas is introduced from the other side of the check valve 145, the disk moves from one side to the other side so that the high-pressure gas can be discharged to one side. When the inflow of the high-pressure gas stops, the disk is moved from one side to the other side Closing the passageway prevents high pressure gas from escaping. Accordingly, the gas injection pipe 144 can prevent the high pressure gas discharged from the gas container unit 120 from being re-introduced into the gas container unit 120 through the check valve 145. One end of the extinguishing agent spray tube 143 is installed in the injection nozzle and the other end is installed inside the inside space 150. The extinguishing agent spray tube 143 is formed so that the diameter of the other end is smaller than the diameter of one end. That is, the extinguishing agent spray pipe 143 is formed in a shape in which the diameter of one end and the diameter of the other end are different from each other.

The extinguishing agent spraying pipe 143 lowers the pressure of the extinguishing agent H through the other end of the extinguishing agent H delivered to the high pressure in the inside portion 150 and then quickly transfers the extinguishing agent H to one end. The extinguishing agent spraying pipe 143 can rapidly spray the extinguishing agent H with a difference between the pressure delivered from the wide internal portion 150 and the pressure reduced at the other end.

5 and 6, the operation and use of the fire extinguisher with the curved ends at both ends of the present invention will be described.

FIG. 5 is an operational view of a fire extinguisher having curved ends at both ends according to an embodiment of the present invention, and FIG. 6 is a state of use of a fire extinguisher having curved ends at both ends according to an embodiment of the present invention.

The fire extinguisher (1) having curved ends at both ends is formed by a curved surface (140) having one end and the other end punctured with an injection port (141), and the fire detection sensor unit And a voltage is applied to the motor unit 130 to operate.

At this time, the motor unit 130 operates to operate the opening / closing unit 131 so that the high-pressure gas G is moved from the gas container unit 120 to the inner container 150 through the gas injection pipe 144. Then, the fire extinguishing agent H can be sprayed through the fire extinguishing agent spraying pipe 143 by moving the fire extinguishing agent H to the spraying nozzle 142. At this time, the spray nozzle 142 may be formed of a spray nozzle and a mist nozzle capable of spraying the extinguishing agent H in a wide radiation angle.

When the fire extinguisher 1 having the curved ends at both ends is thrown by the firefighter with the flame F, the length of the outer casing is inclined by the curved surface 140 so that the jetting port 141 is positioned with the flame F do.

The fire extinguishing sensor unit 160 operates on the enclosure 100 and the fire extinguishing agent H can be sprayed by the flame F as described above.

7 to 8, a fire extinguisher having curved ends at both ends according to another embodiment of the present invention will be described in detail.

FIG. 7 is a vertical sectional view of a fire extinguisher having curved ends at both ends according to another embodiment of the present invention, and FIG. 8 is an enlarged view of the first exterior part of FIG.

The fire extinguisher 1-1 having curved ends at both ends according to another embodiment of the present invention may be manufactured in the same manner as the tactical bulb 1-1 except for the plurality of button portions 170, the sum operation gate 181, the product operation gate 182, Is substantially the same as that of the digestive coal 1 at both ends according to one embodiment.

Therefore, in order to simplify the description of the fire extinguisher (1-1) having curved ends at both ends according to another embodiment of the present invention, the fire extinguisher (1) having curved ends at both ends according to one embodiment may be avoided It focuses on examples that differ from examples.

A fire extinguisher (1-1) having curved ends at both ends according to another embodiment of the present invention may have the same structure as the fire extinguisher (1) having curved ends at both ends according to an embodiment, and the first enclosure (100a-1) And a fire detection sensor unit 160. The control unit 100 includes a control unit 100b-1, an internal combustion engine 150, a motor unit 130, a fire detection sensor unit 160, and the like.

Particularly, the fire extinguisher (1-1) having a curved shape at both ends includes a plurality of button portions (170). The button unit 170 may be installed in both the first enclosure 100a-1 and the second enclosure 100b-1. One end portion of the button portion 170 is exposed to the outside in the lengthwise surfaces of the first and second enclosure portions 100a-1 and 100b-1, the other end portion is located in the accommodation space 110, When an external force is applied, it is displaced and a voltage can be generated. For example, the button portion 170 may be formed of a piezoelectric element. The button portion 170 is provided on the upper and lower sides of the outer casing, and when the length of the outer casing 100 is brought into contact with the bottom surface, the button portion 170 can be pressed and generate a voltage.

The plurality of button units 170 may be connected to an input terminal of the sum operation gate 181 to apply a voltage to the sum operation gate 181.

The sum operation gate 181 is an or gate used in a digital circuit and outputs a digital signal '1' when a voltage higher than a set voltage is applied from one of the plurality of button units 170, When a voltage equal to or higher than the set voltage is applied to all the button units 170, a digital signal '0' can be output. And applies the output signal to one input of the product gate 182.

For example, when a voltage equal to or higher than a noise margin is applied to the sum operation gate 181 on the button portion 170 of the upper side and a voltage less than the noise margin is applied on the lower side button portion 170, Output. When a voltage less than the noise margin is applied to the sum operation gate 181 on the button portion 170 of the upper side and a voltage less than the noise margin is applied on the lower side button portion 170, And is applied to one input terminal of the output calculation multiplication gate 182.

The product operation gate 182 is an AND gate used in a digital circuit, and one button unit 170 and one fire detection sensor unit 160 are connected to an input terminal. When the voltage applied to the input terminal is higher than the set voltage 1 ", and when any one of the digital signals is less than the set voltage, the digital signal " 0 " is output and applied to the switch unit 190. That is, the product arithmetic gate 182 outputs the digital signal '1' only when both the button unit 170 and the fire detection sensor unit 160 are in normal operation, any one of them does not operate normally and the digital signal '0' And applies it to the switch unit 190.

The switch unit 190 is connected to the output end of the product calculation gate 182 to form a voltage path corresponding to the value output from the product calculation gate. The switch unit 190 is formed of a Bipolar Junction Transistor (BJT), for example. The first end of the switch unit 190 is connected to the product gate 182, the second end of the switch unit 190 is connected to the battery unit B, And the third stage may be connected to the motor unit 130. When the digital signal '1' is applied to the product gate 182, the switch unit 190 is turned on and connects the battery unit B to the current path of the motor unit 130 and the transmitter unit 200 Off state and the current path between the battery unit B and the motor unit 130 and the transmitter unit 200 is cut off or disconnected when the digital signal '0' is applied at the product calculation gate 182 .

In other words, the switch unit 190 can prevent or allow current to flow from the battery unit B to the motor unit 130 and the transmission unit 200 according to the magnitude of the voltage applied through the first end.

The transmitter 200 transmits a communication signal to a signal receiving terminal (not shown) and an unmanned airplane 300 carried by an operator and a firefighter. Here, the signal receiving terminal may be a terminal connected to the transmitting unit 200 through a wired connection, and connected to the wired signal or the Bluetooth communication to receive the wireless signal.

Then, the unmanned airplane 300 is a device capable of flying with the operator's radio control after gripping the curved digits 1-1 at both ends. For example, the unmanned airplane 300 can be a drone.

The signal receiving terminal and the unmanned airplane 300 include a receiver for receiving a signal transmitted from the transmitter 200. An indicator 310 that is turned on and off according to a signal received by the receiver .

In one example, the unmanned airplane 300 includes two indicators, one of which may be turned on by a signal transmitted by a transmitter installed in the first enclosure 100, May be turned on by a transmitter installed in the second enclosure (100).

And may be separated from the unmanned airplane 300 as shown in FIG. 10, and may fall into the flame F of the fire area. In addition, the digestive coal (1-1), which is not shown but has a curved shape at both ends, can be moved to the fire area by throwing firefighters. In other words, the fire extinguisher (1-1), which is curved at both ends, can be moved in various ways to the fire area, such as moving on the unmanned airplane (300) or by throwing firefighters.

The fire extinguisher (1-1) having curved ends at both ends can transmit the driving signal to the unmanned airplane (300) in the flame, or can transmit the driving signal to the above-mentioned signal receiving terminal possessed by the operator and the firefighter.

At this time, the unmanned airplane 300 receives the transmitted signal, flies the indicator 310 on or off, and returns to the operator and the firefighter. The worker and the firefighter can be seen through the unmanned airplane 300 to see whether or not the fire extinguisher (1-1) having a curved shape at both ends that are separated by the flame is normally driven.

In addition, the signal receiving terminal receives the signal to be transmitted, turns on / off the indicator in response to the received signal, and the operator and the fireman watch the indicator and determine whether the curved digits 1-1 on both ends are normally driven .

Accordingly, the operator and the firefighter can easily understand how many fire-fighting coils 1-1, which are loaded on the plurality of unmanned air-conditioning units 300 and are curved at both ends, have been operated and some of them have not been operated normally . Further, it is possible to grasp which of the curved fire extinguishers 1-1 at both ends in the flame has been operated normally or the like.

Then, the operator and the firefighter may throw the curved rounded summit (1-1) at both ends again, or carry it on the unmanned airplane (300) and transfer it to the fire area as many times as the normal operation. In addition, the operator and the firefighter calculate how the intensity of the flame changes in correspondence with the number of the digits 1-1, which are both curved at both ends, To the fire area.
