Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a system for preventing a building fire or a forest fire from spreading in a residential area.

2. Description of the Related Art A method of preventing fire spread by changing a building itself to a fire wall is currently used as a method of preventing fire spread, and a method of preventing fire spread by, for example, using a crane to prevent fire from spreading. A method of forming a hanging fire curtain, a method of arranging easily assembling members in various places, and assembling it in the event of a fire to form a fire wall, and a method disclosed in Japanese Patent Laid-Open Publication No. 63-272362. There is a method of erecting a telescopic support on a carriage and mounting the non-combustible sheet on the support.

[Problems to be Solved by the Invention] Even if the building itself is changed to a fire wall, it is costly to assemble a wall having a height of several tens of meters in a bad environment near a fire site. It is more difficult than expected. Also, the method of hanging a noncombustible sheet on a crane to form a fire curtain is unlikely to allow large-sized cranes such as cranes to move freely in the event of a disaster, and it is also possible to combine many cranes at the same time at the same time. Have difficulty. Then, a proposal of erecting a telescopic support on the bogie to make the non-combustible sheet extendable up and down and back and forth on the support, and in addition, the proposal of providing a cooling water discharge means has the advantage of being able to move freely. Precision mechanical operation is required from the drive mechanism such as hydraulic cylinder, annular plunger, annular cylinder, etc. to operate, and a generator, battery, or external power supply is required as a power supply, and water supply for cooling and discharging water It is also necessary to secure such equipment, and it is considered that the manufacturing cost of this device is as high as that of heavy vehicles. And although it can be said that the non-combustible sheet can be vertically extended and retracted vertically, it is not possible to cope with the case where the flame at the time of fire is higher than the upper limit height of the column of the device due to its mechanism. However, it is expected that it will take time to form a fire protection fence with a system corresponding to the fire spot due to the mechanism of the measures that cannot be turned around.

The object of the present invention can fundamentally solve the above problems. Easy to move and assemble, economical, and realistically, the workability to obtain the fire curtain quickly at the fire site is good, and the horizontal and vertical directions for the formation of the fire curtain are arbitrarily selected. It is an object of the present invention to provide a possible fire spread prevention device.

[Means for Solving the Problems] In order to achieve the above object, a winding device which can be easily moved and which can be operated manually even with a power specification has a freely set width and winding length. A non-combustible woven fabric woven of a material mainly composed of ceramic fiber is wound, and a bar made of a heat-resistant resin or light metal for holding the cloth tension at the end of the non-combustible woven fabric is provided on the end face thereof. It is connected, and the joint ring is firmly attached to the bar and the woven fabric, while the inflator or cylinder has a part that can be filled with hydrogen gas or helium gas in a short time, and the surface is protected with fire-resistant material Prepare a mooring rope with a balloon attached and a hook such as a carabiner that can be easily connected to the above-mentioned ring attached to the tip of the incombustible rope for mooring the balloon. It is very easy to carry these to the fire site, and in accordance with the situation, install the winding device on which the non-combustible sheet is wound in a predetermined direction and instantly connect the hook and the joint ring of the non-combustible sheet which is the end connection device of the mooring rope. When the balloon is connected and is filled with hydrogen gas or the like in a short time from an inflator or a cylinder into a small balloon in a gas-free state when not in use, the balloon rises at once and the non-combustible sheet is pulled and extended. When the non-combustible sheet is extended to a required altitude, the winding device is designed to display at regular intervals how much the sheet has been advanced. Then, a brake is applied with a predetermined feeding length by a stopper provided in the winding device to secure a necessary length. Further, the balloon is provided with a plurality of non-combustible ropes that can be pulled and controlled in position when swept away by the wind in the sky. A set of these equipment was carried in as many as necessary according to the situation of the fire site, and a fire curtain was formed at a predetermined position, so that any flame could be surrounded and fire spread could be prevented.

[Embodiment of the Invention] [Example] The drawings show an embodiment of the present invention, wherein 1 is a non-combustible sheet winding device main body which is lightweight but has excellent mechanical strength, and 2 has an arbitrary width and length. Non-combustible sheet selected and wound, 11
Is a balloon filled with gas, 17 is a container into which a gas for inflating the balloon is press-fitted, and 14 is a non-combustible rope for anchoring a balloon to which a hook connected to a joint ring of a non-combustible sheet is attached at its tip.

The normal balloon 11 is degassed and folded small and stored together with the non-combustible sheet take-up device 1 and the inflator or cylinder in a fire department or the like. Put it on another trolley and haul it to the leeward side of the fire site. Thus, the three-piece set of the plurality of balloons 11, the non-combustible sheet take-up device 1, the inflator or the gas cylinder 17 is carried in and arranged at an appropriate position. The fire-retardant sheet winder 1 is installed at an appropriate position by checking the state of the fire and the wind speed on the lee of the fire site, and 1 is fixed at that position using the fixing device 9 of the winder. Next, the one-touch carabiner-shaped hook 16 at the tip of the balloon mooring rope 14 is joined to the joint ring 3, and the injection of gas such as hydrogen from the inflator or cylinder 17 into the balloon 11 is started immediately. The gas discharge port 19 of the cylinder is fitted to the gas inlet 13 on the balloon side, the opening / closing handle 18 at the top of the cylinder is opened, and gas is injected up to the specified value of the balloon pressure gauge 15. This increases the buoyancy of the balloon 11, pulls out the non-combustible sheet 2 to the required length as shown in FIG. 1, stops the flame, and prevents the spread of fire. At this time, the necessary length can be easily determined because the take-up device is provided with a gauge for indicating how much the non-combustible sheet is unwound. It is sufficiently conceivable that the balloon which has risen in a strong wind and rises in the sky is pushed by a considerable wind pressure and flows downwind. In this case, the fire-resistant noncombustible sheet at the angle is similarly swept from the upper part to the leeward side, and becomes oblique, and obstructs the fire prevention effect. Secure fixed. Since the flammable gas is filled in the balloon and the gas cylinder after gas filling, it is a natural measure to make the system not close to the flame.

[Effects of the Invention] According to the present invention, the following effects can be obtained. 1. Each device has a simple structure and is lightweight, so it is easy to carry and move. 2. A fire protection curtain can be formed in a short time at an emergency fire site from its simple structure and system. 3. Because the structure is simple, the production cost of equipment and equipment is unexpectedly low. 4. Depending on the size of the fire, the width and height of the flame,
The size of the fire curtain can be adjusted appropriately and easily. 5. Both devices and systems can be easily operated by amateurs without any special skills. However, it goes without saying that leaders need to be able to judge the speed and time at which the fire spreads due to the fire.
