ている。 In the figure, reference numeral 1 denotes a G sensor, which is a seismic sensor, and has the function of sensing a predetermined seismic intensity, for example, the impact when a vehicle collides, and sending a signal to a pressure feeder, which will be described later. Reference numeral 2 denotes a pressure feeder, which is activated by a signal from the G sensor 1 and blows out air or a predetermined gas at high pressure from a protruding feed pipe 3. Reference numeral 4 denotes a gelling agent storage tank, in which a gelling agent 5 is hermetically sealed, and a feeding pipe 3 is connected to the upper part. 6
is a delivery pipe, and the gelling agent storage tank 4
The lower end reaches near the bottom of the gelling agent storage tank 4. 7 is a gasoline tank for the vehicle, which stores gasoline 8 and is attached to the vehicle body 9.
and is connected to the delivery pipe 6, the end of which is located at the bottom of the gasoline tank 7.

生を防止する。 In this embodiment having the above configuration, when a vehicle equipped with the ignition prevention device for a flammable liquid tank according to this embodiment collides due to an accident, the gasoline tank 7
If a crack occurs, first, the G sensor 1 senses the impact caused by the collision and sends a signal to the pressure feeder 2. Upon receiving the signal, the pressure feeder 2 is activated and blows out high pressure air or high pressure gas from the feed pipe 3 into the gelling agent storage tank 4 . This increases the internal pressure inside the gelling agent storage tank, and this internal pressure forces the gelling agent 5 into the gasoline tank 7 via the delivery pipe 6, where it mixes with the gasoline 8 remaining in the gasoline tank 7. The gasoline 8 is made into a gel by a chemical reaction, which prevents the gasoline from flowing out through the cracks formed in the gasoline tank 7 and makes it nonflammable, thereby preventing the occurrence of a fire due to the gasoline flaming.

For example, 15% Gelol D powder is dissolved in N/N-dimethylacetamide, and Gelol D or Gelol T is derived from the condensation reaction of D-sorbitol and benzaldehyde (hydrophobic When 10 to 30% of this gelling agent is injected into gasoline, the gasoline instantly turns into a gel and seals the cracks in the tank. Since it does not flow out and becomes unnatural as a result of this gelation phenomenon, it is possible to prevent gasoline from igniting. In addition, in the above-mentioned example, the case where the present invention was implemented in a car was shown, but
The same goes for boiler oil tanks; by instantly injecting a gelling agent into the oil tank using a sensing mechanism that detects boiler explosions or earthquakes, the oil gels and cracks in the oil tank are removed. Prevent oil from spilling,
This can prevent oil from catching fire.

に行わしむることを可能とするものである。 As explained above, in the present invention, when a tank serving as a storage container for gasoline, other volatile oil, oil, etc. is damaged by various impacts, the gasoline, etc. is instantly turned into a gel, thereby removing the damaged part from the damaged part. It prevents gasoline from leaking outside and makes it non-flammable. It prevents secondary disasters such as fires at the accident site, protects human lives from such fires, and facilitates rescue operations following the initial accident. This makes it possible to do so safely.
