Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, 2, and 3:
according to the forest fire extinguisher 100, the hollow cylindrical outer cover 1 is provided with the hollowed grid-shaped through holes, the lower cover 8 clamped at the lower end of the outer cover 1 is provided with the hollowed grid-shaped through holes, the upper cover 5 is clamped at the upper end of the outer cover 1, and the outer cover 1, the lower cover 8 and the upper cover 5 are all made of engineering nylon plastics.
A water-proof paper or thin plastic water bag 7 is hung on the hanging ring 51 on the lower surface of the upper cover 5, and the water bag 7 is accommodated in the outer cover 1.
The waterproof water bag 7 is filled with a fire extinguishing agent 71, and the fire extinguishing agent 71 can be water or an existing water-containing fire extinguishing compound.
A pressure expansion driving device 6 is hung on the hanging ring 51 and is immersed in the fire extinguishing agent 71.
The pressure expansion driving device 6 comprises an aluminum foil bag 61 immersed in a fire extinguishing agent 71, and the aluminum foil bag 61 is filled with a reactive powder 62, such as lime or magnesium powder, which reacts violently with water and is driven by pressure expansion.
A glass tube 63 is plugged at the opening of the aluminum foil bag 61, the glass tube 63 is filled with filling liquid with higher thermal expansion coefficient (all are high-expansion-rate liquid which can be boiled at low temperature, the expansion coefficient of the filling liquid is larger than that of the glass, ester, alcohol, ethanol, ether and the like are selected according to different operating temperatures, and as long as the temperature change is small, the liquid volume expands to generate large internal pressure to break the glass body), an electric heating wire 64 is wound outside the glass tube 63, a sealing adhesive 65 is filled in a gap between the glass tube 63 and the electric heating wire 64 and the aluminum foil bag 61, and the sealing adhesive 65 plays a role in sealing the opening of the aluminum foil bag 61 and fixing the glass tube 63 and the electric heating wire 64 at the opening position of the aluminum foil bag 61. The electric heating wire 64 is connected to a power source by a wire 66.
The bottom of the lower cover 8 is provided with a smoke detector 9, and the smoke detector 9 is connected with a control circuit board 10 (figure 4) and a power supply. An audible and visual alarm connected to the control circuit board 10 may also be provided.
An annular hoop 3 with an opening is connected to the top end of the upper cover 5, an annular silica gel ring 4 is fixedly arranged in the annular hoop 3, and the screw and nut combination 2 can be locked after penetrating through the opening of the annular buckle 3.
The power source may be a solar cell.
As shown in fig. 4:
the control circuit board 10 has a signal transmitting and receiving module 11, and the signal transmitting and receiving module 11 is connected with the control center processor 12 through the internet.
In actual use:
several forest fire extinguishers 100 are arranged in a forest.
The clamping object can be selected from branches and can also be selected from an installed hanging rod.
The annular silica gel ring 4 is clamped on a clamped object in a wrapping mode, the screw and nut combination 2 penetrates through the opening of the annular buckle 3 and then is locked, the clamped object is clamped due to elasticity of the annular silica gel ring 4, and the whole forest fire extinguisher 100 is hung on the clamped object.
When a fire occurs below the forest fire extinguisher 100, the smoke detector 9 sends a signal to the control circuit board 10 after detecting the fire.
The control circuit board 10 is connected with a circuit composed of the electric heating wire 64, the electric wire 66 and the power supply, the electric heating wire 64 heats the glass tube 63, and the sealed glass tube filled with the organic solution with the higher thermal expansion coefficient in the glass tube 63 expands until the glass tube 63 is crushed. Thereby the opening of the aluminum foil bag 61 is opened, and since the aluminum foil bag 61 is immersed in the fire extinguishing agent 71, the fire extinguishing agent 71 enters the aluminum foil bag 61 from the opening of the aluminum foil bag 61, and is mixed with the reaction powder 62 (lime or magnesium powder), thereby generating pressure expansion driving, and the water bag 7 is burst, and the fire extinguishing agent 71 is sprinkled on the fire below through the hollow grid-shaped through holes of the outer cover 1 and the lower cover 8 to extinguish the fire.
The control circuit board 10 controls the audible and visual alarm to give an alarm.
Meanwhile, the control circuit board 10 sends the position signal of the forest fire extinguisher 100 to the control center processor 12 through the signal transmitting and receiving module 11, so that a control person can know where the forest fire extinguisher fires immediately, arrange the personnel to put out the fire ahead, send a signal to the signal transmitting and receiving module 11 of the nearby forest fire extinguisher 100, and then control the forest fire extinguisher to explode the pressure expansion driving device 6 through the control circuit board 10, and cover the area which can fire with the fire extinguishing agent 71.
After the water bag 7 is burst by the pressure expansion driving device, the outer cover 1, the lower cover 8 and the upper cover 5 are all made of engineering nylon plastics and can be reused, and only the new water bag 7 filled with the fire extinguishing agent 71 and the new pressure expansion driving device 6 are needed.
