A kind of flame retardant isolation frame used for forest flying fire prevention

Abstract

The invention discloses a flame-retardant isolation frame for forest flying fire prevention, and relates to the technical field of forest fire prevention equipment. It includes a support and a folding screen used in conjunction with it, and the folding screen is a rigid structure; the support is installed on the ground and is used to support the folding screen; the number of the folding screen is at least one and is arranged on an adjacent Between the two supports; the folding screen adopts a hollow structure, and at least one folding indentation is pressed on the folding screen; the support is provided with a pipeline made of a good heat-conducting material, and the pipeline is a sealed structure, The pipeline is filled with a solvent with a boiling point in the range of 36°C-65°C, and the pipeline communicates with the folding screen. The invention can convert the heat energy of forest burning into the mechanical energy of folding curtain along the indentation recovery, so that when the forest temperature is abnormal and reaches a critical point, it can automatically stretch and resist wind and fire, without the need for limited energy such as electricity and petroleum to drive. And it is flame retardant itself, which greatly reduces the loss of forest fires.

Description

technical field [0001] The invention relates to the technical field of forest fire prevention equipment, in particular to a flame-retardant isolation frame for forest flying fire prevention. Background technique [0002] Forest fire is a natural disaster that is sudden, destructive, and difficult to deal with and rescue. Forest fires that occur all over the world cause tens of billions of losses every year. The occurrence and spread of forest fires are related to many factors, such as moisture content of forest vegetation, composition of tree species, stand canopy density, soil, terrain and meteorological conditions, among which meteorological conditions have a greater impact on forest spread. Among many meteorological conditions, wind is an important factor affecting the risk of forest fires. On the one hand, wind can take away the moisture in the air, which reduces the humidity in the forest and accelerates the drying of combustibles; on the other hand, if the forest has a...

Among many meteorological conditions, wind is an important factor affecting the risk of forest fires. On the one hand, wind can take away the moisture in the air, which reduces the humidity in the forest and accelerates the drying of combustibles; on the other hand, if the forest has already When a fire breaks out, the heated air will continue to form a vortex upwards, and the wind will continuously send fresh air and oxygen from the lower part to the burning place to replace the heated air, making the fire more fierce and difficult to control

And although the loss is reduced by setting up the forest fire protection zone, under the action of the wind, the ignited branches and leaves will be blown to the distance, causing flying fire, and it is easy to cross the fire protection zone to spread the fire
