Description

{fire extinguishing and diffusion delay apparatus}

The present invention relates to a fire suppression and spread delay device, and in particular to a fire suppression and spread delay device that can suppress or delay the spread of a fire such as a forest fire and spread to cultural assets such as houses or temples. will be.

In Korea, there are many mountainous areas, so many forest fires occur. To extinguish forest fires, a large amount of fire water or fire extinguishing agent is sprayed from the air using an aircraft, and when the large fire is extinguished to some extent, ground firefighters are brought in to control the remaining fire. It is common to extinguish fires, etc.

However, if a forest fire cannot be identified and extinguished at an early stage, or if the forest fire spreads rapidly due to strong winds, etc., it spreads and invades cultural properties such as houses, factories, and temples, resulting in significant damage to not only life but also property. Occurs.

In Korea's urban areas and other areas, many facilities are located close to mountains, and in particular, farms or cultural heritage temples are very vulnerable to forest fires because they are located in or close to mountains.

When a forest fire spreads to farms, etc., it is very important to suppress the forest fire to a certain extent or delay it for a certain period of time until fire suppression equipment and personnel arrive, but such facilities are almost non-existent in farms.

In the case of cultural properties such as temples, firefighting facilities are equipped, but these are not for extinguishing forest fires, but rather for extinguishing fires in the cultural properties themselves. They are used to suppress and delay forest fires in case the forest fire spreads and invades. It is not a facility.

In addition, installing firefighting facilities to prevent forest fires from invading requires a lot of money and is very difficult to install.

For example, various facilities are required, such as various sensors to detect forest fires, tanks to accommodate fire-fighting water, facilities to prevent fire-fighting water from freezing, power for pumps to spray fire-fighting water, and installation of power cables to supply power. This makes installation difficult, resulting in high installation and maintenance costs.

Therefore, there is a need for a device that can suppress the spread of forest fires and prevent them from approaching facilities such as houses, factories, and temples to some extent while delaying them for a certain period of time, and is also inexpensive and very easy to install.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments of the present invention illustrated below may be modified into various other forms, and the scope of the present invention is not limited to the embodiments detailed below.

Examples of the present invention are provided to more completely explain the present invention to those skilled in the art.

Figure 1 is a diagram showing the cross-sectional structure of a fire suppression and spread delay device according to an embodiment of the present invention, and is largely composed of a body 100, a release portion 130, and a cover 150.

The body 100 is a cylindrical body with an opening 102 with an open top, accommodating a fire extinguishing agent in powder form, and an elastic part 120 and a pressure plate ( 110) is built in, and the elastic part 120 is a spring that maintains a compressed state by the release part 130, and the pressure plate 110 is located on the upper side of the elastic part 120 to maintain the elastic part 120. It has a structure that goes up and down due to the elasticity of (120).

This pressure plate 110 is in the shape of a disk, and an O-ring 111 is installed around the outer periphery to maintain an airtight state with the inner wall of the body 100 and allow it to be raised and lowered by the elastic portion 120.

Fire extinguishing agent 170 is accommodated on the upper side of the pressure plate 110.

In addition, a fixing part 140 with a sharp lower end so that it can be driven into the ground is provided downward from the lower part of the body 100, so that the body 100 can be erected and fixed from the ground, and the lower side of the body 100 A plurality of supports 141 in the form of a tripod are provided around the circumference to stably maintain the erected state of the body 100.

The release part 130 maintains the compressed state of the compressed elastic part 130, releases the compressed state of the elastic part 130 by the heat of a forest fire, and uses the elastic force of the elastic part 130 to apply fire extinguishing agent. Let it flow out through the opening 102.

For this purpose, a hinge 132 is installed on the outside of the body 100 where the elastic part 120 is located, and a restraint 131 is installed to rotate in the vertical direction by the hinge 132. (131) is an elastic portion (120) whose upper portion is bent around the hinge (132) in the direction of the body (100) and inserted into the inside of the body (100) through the through hole (101) formed in the body (100) and compressed. By being caught, the expansion of the elastic portion 120 is prevented.

The lower portion of the restraint section 131 centered on the hinge 132 is bent toward the outside of the body 100, and the restraint release elastic portion 133 and the restraint retainer 134 are connected to the bent portion. It has a structure.

The restraint release elastic part 133 is a spring that pulls the lower part of the restraint period 131. The upper part is connected to the lower side of the restraint period 131, and the lower part is located on the lower side of the restraint period 131. It is connected to the body 100.

Accordingly, the restraint section 131 is released from the locked state of the elastic portion 120 by the restraint release elastic portion 133, causing the elastic portion 120 to expand.

In addition, the restraint holding portion 134 is in the form of a wire or plate, and its lower portion is connected to the restraint rod 131, and its upper portion is connected to the body 100 above the restraint rod 131 to restrain it. The liver 131 is kept tied to the elastic portion 120 to prevent it from expanding.

This restraint holding portion 134 is formed in the form of a wire made of synthetic resin material such as acrylic, PE, PP, PET, etc., and has heat resistance of about 70 to 120°C so that it can be cut or deformed such as elongation by the heat of a forest fire.

Alternatively, the restraint retaining portion 134 may be formed of a metal material that expands by heat, for example, a bimetal, and the restraint release elastic portion 133 and restraint retainer 134 may be formed of a compressed elastic portion 120. The state of equilibrium is maintained by equal force so that the restraint rod 131 in a restrained state does not rotate.

A plurality of such release parts 130 may be provided at regular intervals along the outer circumference of the body 100.

Alternatively, the release unit 130 may be installed at a position that restricts the elevation of the pressure plate 110, and the elastic portion 120 also maintains a compressed state due to the restraint of the pressure plate 110.

The cover 150 closes the opening 102 to prevent foreign substances from outside, such as rainwater, snow, and fallen leaves, from flowing into the interior of the body 100, and opens the opening 102 by the outflow pressure of the fire extinguishing agent 170. By opening, the outflow space is secured in the upper part of the body 100 by being lifted upward by the pressure of the extinguishing agent 170 flowing out. It has a dome shape so that the extinguishing agent 170 can spread laterally. , it can have various shapes such as hat shape, flat shape, etc.

It is desirable that the cover 150 does not completely separate from the body 100 in order to secure an outflow space for the fire extinguishing agent 170 and to spread the fire extinguishing agent 170. To this end, the bottom portion of the cover 150 is completely separated from the body 100. It has a stopper 152 structure to prevent it from coming off.

That is, on the inner upper wall of the body 100, a plurality of rails 103 with long holes 104 formed in the vertical direction are installed at intervals, and the cover 105 is installed in the area corresponding to the rails 103. A plurality of rods 151 extend downward from the bottom of the rod 151, and a bent stopper 152 is provided at the lower end of the rods 151.

Therefore, the rod 151 is inserted into the rail 103 and the stopper 152 is inserted into the long hole 104 so that the stopper 152 is caught on the upper side of the long hole 104 when the cover 150 is lifted upward. By limiting the lifting distance of the cover 150, complete separation of the cover 150 from the body 100 is prevented and the fire extinguishing agent 170 is spread smoothly.

The operation of this embodiment of the present invention will be described.

First, the elastic portion 120 is inserted through the opening 102 of the body 100, and then the upper portion of the restraint section 131 is rotated in a compressed state to insert the elastic portion 120 through the through hole 101. The expansion is restrained by hanging, and in this state, the restraint holding part 134 is connected to maintain the restraint state of the restraint rod 131.

Thereafter, the pressure plate 110 is placed on the upper side of the elastic part 120 by inserting the opening 102 into the body 100 and then receiving the fire extinguishing agent 170 through the opening 102.

After accommodating the fire extinguishing agent 170, the cover 150 is placed on the upper side of the body 100, and the rod 151 is inserted into the rail 103 and pushed downward, the stopper 152 is formed into a long hole ( As it is inserted into 104 and moves downward, the cover 150 blocks the opening 102 of the body 100.

In this state, when the worker drives the body 100 vertically into the ground, the fixing part 140 is driven into the ground and the body 100 is erected, so that the erected state can be stably maintained by the support part 141. do.

Additionally, barbed wire may be installed around the outer circumference or surrounding area of the body 100 to prevent the present invention from being damaged or knocked over by animals.

Therefore, workers install several at intervals in the form of a forest fire prevention line at locations where forest fire invasion is expected, for example, about 50 to 100 meters away from cultural properties such as private houses, factories, and temples in the direction of the mountain. Installation is very quick and easy because the invention only needs to be driven into the ground.

If a forest fire occurs and approaches the area where the present invention is installed, the restraint retaining portion 134 is cut or deformed, such as elongation, due to the heat, thereby breaking the balance of force with the restraint release elastic portion 133. The restraint release elastic portion 133 pulls the lower side of the restraint section 131 toward the body 100.

Accordingly, the upper part of the restraint section 131 separates from the elastic portion 120, causing the elastic portion 120 to expand, and as a result, the pressure plate 110 moves up and down and pushes the fire extinguishing agent 170 upward, thereby extinguishing the fire. As the medicine 170 lifts the cover 150 with pressure, it is guided laterally by the cover 150, that is, in the peripheral direction, and spreads as it flows out.

Therefore, it is possible to suppress forest fires close to the surrounding area of the present invention or delay the invasion of forest fires for a certain period of time by forming a forest fire prevention line by the leaked and diffused fire extinguishing agent 170.

In the present invention, if the diameter of the area where the fire extinguishing agent 170 spreads is, for example, 10 m, a forest fire prevention line can be easily formed by installing it every 10 m.

Figure 2 is a road showing another embodiment of the present invention, which has an ejection pressure by accumulating the fire extinguishing agent 270 inside the body 200, and a cover 250 on the upper side of the body 100. ) is located, the airtight member 251 provided on the lower part of the cover 250 airtightly blocks the opening 202 to prevent the internal fire extinguishing agent 270 and pressure from leaking out to the outside, and the release part ( 230) to prevent the cover 250 from coming off due to pressure inside the body 200.

This airtight member 251 has a shape that airtightly closes the opening 202 by elastic force, and has a cylindrical shape protruding downward from the center of the cover 25, so as to airtightly seal the opening 202. It is inserted and may become more pointed towards the lower part of the lower part.

In addition, the bottom of the cover 250 has a structure in which a plurality of locking portions 253 are installed at intervals in the lateral direction of the airtight member 251.

The body 200 is provided with a fixing part 240 and a support part 241 as shown in FIG. 1.

The release part 230 causes the cover 250 with the airtight member 251 to rise and fall due to the heat of the forest fire to open the opening 202, thereby allowing the accumulated pressure fire extinguishing agent 270 to flow out to the outside. Hinges 232 are installed at positions corresponding to the locking portion 253 on the outside of the body 200 where the opening 202 is located, and the restraints 231 are rotated in the vertical direction by the hinges 232. ) is installed, and the upper portion of the restraint 231 is bent around the hinge 232 so that it can be inserted and caught from the outside in the locking portion 253, and this restraint 231 is connected to the locking portion 253. A spring-shaped restraint release elastic portion 233 is connected in a compressed state between the body 200 and the upper portion of the restraint section 231 so that the restraint can be released by breaking away from the restraint.

In addition, the lower part of the restraint period 231 is connected to the lower part of the restraint period 231 around the hinge 232, and one side of this structural maintenance part 234 is connected to the lower part of the restraint period 231. It is connected, and the other part is connected to the body 200 at the lower part of the restraint section 231.

Therefore, when the restraint retaining portion 234 is cut or deformed such as elongation occurs due to the heat of a forest fire, the restraint release elastic portion 233 pushes the upper side of the restraint member 231 to separate it from the locking portion 253. As a result, the cover 250 is pushed by the pressure of the fire extinguishing agent 270 and rises upward, causing the fire extinguishing agent 270 to be ejected.

At this time, a stopper composed of an elastic part 254 made of a spring or a wire 252 is provided between the body 200 and the cover 250, so that when the cover 250 is lifted up and down, the elastic part 254 is lifted by the lifting force. ) is extended to limit the lifting distance to prevent the cover 250 from being completely separated from the body 200.

In addition, the upper part of the airtight member 251 deviates from the opening 202 due to the limitation of the lifting distance of the cover 250 by the stopper, but the fire extinguishing agent 270 is prevented by the sharp lower part of the airtight member 251. By ejecting pressure through the space between the opening 202 and the airtight member 251, it can be easily and widely spread to surrounding areas by the cover 250.

Meanwhile, in the present invention, it is possible to extinguish or delay a forest fire by discharging the fire extinguishing agent without power due to the heat of the forest fire. An alarm signal for this operating state, that is, an alarm signal notifying that a forest fire is approaching, is sent to the destination, that is, the resident's smartphone. , it can have the function of notifying the temple manager's smartphone, a remote fire and disaster prevention center, etc.

For this purpose, the covers 150 and 250 or the bodies 100 and 200 are provided with a solar panel 300 and a circuit unit 400, where the circuit unit 400 includes a charging circuit that charges the power generated from the solar panel 300. battery 410, a sensor unit 430 for detecting the open state of the cover (150, 250) or the operating state of the release unit (130, 230), and a memory 450 based on information sensed from the sensor unit 430. It consists of a controller 420 that reads destination information previously stored in the system, that is, the resident's phone number, the manager's phone number, the fire and disaster prevention center's phone number, etc., and transmits an alarm signal through the communication unit 440.

The controller 420, sensor unit 430, and communication unit 440 are operated by power charged in the battery 410, and the sensor unit 430 is in the form of a micro switch when the covers 150 and 250 are raised and lowered. It may generate an 'ON' signal, and may also be a sensor in the form of various switches that detects that the release units 130 and 230 are operating.

Therefore, when an input is generated from the sensor unit 430, the controller 420 operates the release units 130 and 230 as a forest fire approaches, and accordingly, the covers 150 and 250 are normally opened, allowing the extinguishing agent 170 and 270 to flow out. It is determined that a forest fire is approaching, and by using the current operating state as an alarm signal and generating an alarm signal through the communication unit 440 based on the destination information stored in the memory 450, it is quickly notified that a forest fire is approaching.

The communication unit 440 preferably uses a mobile communication network, and recognizes that a forest fire is approaching by this alarm, and dispatches equipment and manpower to respond to it. Before the equipment and manpower arrive at the scene, the forest fire is prevented by the present invention. The spread of forest fires can be delayed by suppressing them to some extent.

Figure 3 shows another embodiment of the present invention, as shown in Figure 2, an electromagnetic valve 280 is installed at the opening 202 of the body 200 containing the accumulated pressure fire extinguishing agent 270 to prevent the outflow of the extinguishing agent 270. is prevented, and when heat is detected by the sensor unit 430 that can detect the heat of a forest fire, the controller 420 opens the electromagnetic valve 280 to allow extinguishing agent with pressure to be ejected.

At this time, the cover 250 is raised and lowered by the ejection pressure of the fire extinguishing agent 270 to enable even spraying to the surrounding area.

In Figure 3, the airtight member 251 in Figure 2 is replaced with an electromagnetic valve 280, and the release parts 130 and 230 are deleted, and other structures are the same or similar, so detailed descriptions are omitted.

In addition, the release parts 130 and 230, the electronic valve 280, etc. as described above may be mechanical, electronic, or a mixture of mechanical and electronic, and may have various structures capable of spraying fire extinguishing agents.
