Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic fire extinguisher and an alarm attached to a ceiling.

[0002]

[Prior art]

 There are two types of fire extinguishers: a cylinder type filled with a fire extinguisher that is injected by operating a manual lever, and a cylinder type filled with a fire extinguishing agent that is automatically injected when the temperature of the well is increased. Most fire alarms require a power source.

[0003]

[Issues to be solved by the device]

 Among the causes of fire, it is said that the ignition of oil in the pot is high. Even if you have a cylinder-type fire extinguisher installed in your home, you will not be aware of the installation of the fire extinguisher in an emergency, and you will not be able to operate the fire extinguisher properly, and you will be taught to cover a wet blanket with a ignited pot. When faced with, it is often difficult to implement and it is too late to extinguish the fire. The disadvantage is that fire extinguishers that are installed on the ceiling and automatically inject are expensive. If the price of the fire extinguisher is low, it will be easy to spread. Even if an oil fire in a pot is extinguished by an automatic fire extinguisher, an alarm is necessary because it will refire if left unattended without returning to the site. Use an alarm device that does not use a power source.

[0004]

[Means for Solving the Problems]

 Connect a suspension line hanging from the ceiling to a flammable container or bag containing extinguishant, and attach a restraint to hold it on the ceiling. When the temperature rises to about 40 ° to 80 ° C, the restraint is released and the flammable container or bag containing the extinguishant drops to the ignition point immediately below and is suspended and the container opens due to flame heat and the extinguishant is sprayed on the pan to extinguish the fire. To do.

In order to generate a sound when the ambient temperature rises, the energy storage means is provided with a lock release device for changing the temperature. When the lock is released, a warning device that releases the stored energy and sounds is installed on the ceiling.

[0006]

[Action]

 A container or bag containing extinguishant was connected from the ceiling so that it could be suspended and suspended, and it was restrained on the ceiling, and a restraint release device was attached to it due to temperature changes. When the temperature rises by 40 to 80 ° C, the restraint release device operates and the container or bag containing the extinguishant drops and is suspended on the pan by the branch line, and the container and bag are opened by flame heat and sprayed on the oil in the pan. extinguish a fire. The fire alarm will be installed on the ceiling by attaching a lock release device for temperature change to a sound generator powered by a mainspring or gas pressure. When the oil in the pot catches fire and the ceiling temperature rises to approximately 40 ° to 80 ° C, the lock is released and an alarm is issued. Even if an automatic fire extinguisher can extinguish the oil in the pot, it will reignite unless the heat source is stopped, so an automatic alarm is also important, and it is possible to prevent the fire from occurring.

【Example】

 Referring to the drawings, FIG. 1 shows two examples, A and B. For example A, connect the wire 2 suspended from the ceiling to the flammable container 1 with fire extinguisher, wrap it, attach the terminal to the ceiling, and bind it to the ceiling with the tegus 3. Set the blade of the scissors 5 on which the memory alloy 4 is hung. A pillow 6 is inserted to set a blade on the Tegus. FIG. 2 shows a situation where the oil in the pot 11 is ignited when the example A is restrained on the ceiling 10. Immediately when the ceiling temperature rises to about 40 °, the shape memory alloy 4 stress causes the blade of the scissors 5 to cut the restraint 3 to release the restraint, and the container 1 descends and is suspended by the wire 2 on the pot. . The container is opened by flame heat and the extinguishing agent is sprayed on the pot 11 to extinguish the fire. Although not shown in the figure, if the restraint means of the flammable container 1 containing the extinguishant is a temperature fuse, the temperature fuse is cut at the ceiling temperature of about 72 ° C, the restraint is released, the extinguishant container drops, and flame heat is generated. The container or open fire extinguisher is sprayed on the pan to extinguish the fire. If the restraint means is scissors in which Tegus and a shape memory alloy are engaged, Tegus has the advantage that it is strong and can be easily cut by a blade at 40 ° C.

In the example B of FIG. 1, a wire 2 hung from the ceiling is connected to a bag containing an extinguishant, and the wire 2 is wrapped around and placed in a sphere 8 that opens in two as restraining means. The scissors blade with shape memory alloy 4 hung on the nigiri is set on the Tegus. This fire extinguisher is kept on the ceiling for a long period of time, so a cover 9 is put on it to prevent sticky materials from sticking to the scissors and impairing the function of the scissors. Fig. 2 shows a state in which example B is restrained on the ceiling 10 and the oil in the pot ignites. When the oil in the pot ignites, the temperature of the ceiling rises to about 40 ° C, and the stress of the shape memory alloy 4 causes the blade of the scissors to cut the gut 3 and release the restraint. The sphere 8 which is the restraint means opens, and the extinguishant bag 7 is suspended on the falling pan 11, and the bag 7 is opened by flame heat and the extinguishant is sprayed on the pan to extinguish the fire. Although not shown in the figure, if a thermal fuse is installed on the lower two corners of the sphere that opens in two as restraint means, the thermal fuse will be cut at the ceiling temperature of about 72 ° C and the binding will be released and the fire extinguisher bag will be removed. Descent and extinguish the fire.

FIG. 3 shows scissors 5 for cutting and opening Tegus, which is a means for restraining the extinguishant on the ceiling, at about 40 ° C. The tip of the scissors 5 is folded into a U-shape like 12, a blade 13 is fixed on one side, and a hole 12 for holding a tex is provided on the other side. This is important because the Tegu is always on the blade. The shape memory alloy 4 hung on the grip of the scissors 5 shrinks when the ambient temperature reaches about 40 ° C., and the action of the scissors causes the blade 13 to cut the tex in the hole 12.

In FIG. 4, a pipe and a cock 16 are connected to a gas-compressed can 15, which is an energy storage means, and a whistle 17 is connected to the pipe. The coil spring 20 and the gut 3 are distributed to the lever 18 of the cock, and each terminal is fixed to the fixing portion 19. The blade of the scissors 5 with the shape memory alloy 4 hung on the nigiri part is set on the Tegus 3 and is in a locked state. When the ambient temperature reaches about 40 ° C., the stress of the shape memory alloy 4 causes the gut 3 to be cut by the scissors 5, the lever 18 to be pulled by the spring 20, the gas in the can 15 to be ejected, and the whistle 17 to sound and to give an alarm. Although not shown, the coil spring 20 and the thermal fuse are fixed to the lever 18, and the distribution end is fixed to the fixing portion 19. When the ambient temperature rises to about 72 ° C, the thermal fuse is cut, the lock is released and an alarm is issued.

Although not shown in the drawing, a stopper is attached to the mallet part of the spiral spring bellows, and a spring and a tegu are attached to this, and each pulling end is fixed while the mallet part of the body is locked. Set the blade of the scissors with the shape memory alloy engaged to the Tegus. When the ambient temperature reaches about 40 C, the shape memory alloy stress causes the gut to be cut by the scissors, and the spring pulls the stopper on the mallet to release the lock, hit the bell and give an alarm. The spring and the thermal fuse are distributed and fixed to the stopper of the mallet, and when the ambient temperature rises to about 72 ° C, the temperature fuse is disconnected, the spring pulls the stopper and the lock is released, and an alarm is issued.

[Effect of device]

 It is said that there is a high rate of inadvertently leaving the site during the cooking of tempura and catching fire in the oil in the pan, causing a fire. Even if you have a fire extinguisher installed in your home, in an emergency, you may not be aware of the fire extinguisher, it may be too late because you cannot operate it, or you may be taught to cover the pot with cloth. is there. Most fires can be prevented if the fire extinguishing agent falls from the ceiling and extinguishes automatically at the same time as an oil fire in the pot as in this plan. Even if the fire is extinguished automatically, if it is left carelessly and it is left as it is, it will re-ignite, so a fire alarm is necessary. It is considered that this plan is easy to spread because it has a simple configuration that does not use electricity and its price is low.
