technical field

The utility model relates to the technical field of fire escape, in particular to a forest fire protection cover.

Background technique

The disposal of major forest fires is still a worldwide problem. During the actual fire fighting process of forest fires, hidden dangers exist all the time, because forest fires occur in open ecosystems and are affected by various Influenced by factors, forest fires are extremely complex, and there are no roads in many places, which brings great difficulties to fire fighting and search and rescue work.

When firefighters are surrounded by fire in forest firefighting, the way to escape is to rush out of the fire, but the firefighters wear fire suits that cannot withstand larger fires, and if they cannot rush out of the fire, they will lose the chance of rescue. The threat to the lives of firefighters is also the smoke generated by the fire. If the surrounding fire can be controlled and the rescue is waited for within a safe fire range, the chance of escape will be greatly improved.

SUMMARY OF THE INVENTION

Detailed ways

The following are specific embodiments of the present utility model combined with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

As shown in Figure 1-2, a forest fire protection cover includes a cover body 1, a cover bottom 2 and a cover top 3 made of fireproof materials. The cover body 1 and the cover top 3 are both telescopic structures, and the upper end of the cover top 3 Open and arc-shaped, two handles 31 are symmetrically arranged on both sides of the top, and two straps 4 are arranged on the inner side of the cover bottom 2. The strap 4 is an adjustable strap for firefighters of different physiques. A compressed oxygen self-rescuer 5 is also fixed.

Compressed oxygen self-rescuer, also known as isolated compressed oxygen self-rescuer, is a reusable self-rescuing escape device that uses high-pressure compressed oxygen as an oxygen source. It mainly occurs in coal mines or ordinary atmospheric pressure operating environments. Used in disasters. The interior of the human respiratory system is isolated from the outside world, which is used by people in distress to quickly rescue themselves and escape. It has the characteristics of light weight, small size, comfortable breathing and easy portability.

In further detail, the closed ends of the cover top 3 are respectively provided with magnetic strips 6 that attract each other, and the two magnetic strips attract each other to close the cover top 3. The cover top 3 can be closed by attracting the two magnetic strips 6 to each other to prevent the flame from entering the protective cover. It is convenient and convenient to use, and is convenient to use when the situation is critical. Prevent smoke from entering the protective cover and ensure the safety of firefighters in the protective cover.

In further detail, the closure of the two ends of the cover top 3 is also provided with a secondary closed structure, and the secondary closed structure includes a convex strip 7 arranged at one end and a closed groove 8 symmetrically arranged at the other end, and the convex strip 7 is sealed with the closed groove 8. In cooperation, the protruding strips 7 are made of rubber, which further prevents smoke from entering the protective cover and ensures the safety of firefighters in the protective cover.

Preferably, the inner side of the cover bottom 2 is also provided with a sound alarm 9. When the firefighter enters the protective cover, a distress signal can be sent to the outside world through the sound alarm 9, so that nearby rescuers hear the alarm and find themselves rescued in time.

In further detail, the cover body 1 and the cover top 3 include an aluminum coating layer, a silicon-titanium fireproof layer, a ceramic fireproof layer and a heat insulation layer, and the aluminized layer has the function of reflecting radiant heat; It can be used for a long time at 900 °C; the highest refractoriness of the ceramic fireproof layer is 1300 °C, which can be used for a long time at 1000 °C, and has the advantages of high temperature resistance, low thermal conductivity, thermal shock resistance, and low heat capacity; the thermal insulation layer can effectively Prevent the high temperature outside from affecting the temperature inside the protective cover, making firefighters safer when they are inside the protective cover.

To further elaborate, the cover bottom 2 is made of rock wool board. The rock wool board is very stable in size, will not stretch, shrink or deform in a fire, and is resistant to high temperature. 2 on the security.

In further detail, one end of the cover top 3 is provided with a laser generator 10. When the cover top 3 is closed, the laser beam emitted by the laser generator 10 is irradiated towards the sky to form a beam of light, and rescuers who are in the distance can be determined by the position of the beam of light. The position of the trapped firefighters should be rushed to rescue in time. When a forest fire occurs, there is more smoke, and the light beam formed in time is more conspicuous. Compared with the sound alarm, the light beam transmits the rescue signal farther, which greatly reduces the sacrifice rate of firefighters. It is convenient for rescuers to locate rescue.

In further detail, the cover bottom 2 is provided with a fireproof foot cover 11. When the firefighter is trapped and has to move the location, he can put his foot into the fireproof foot cover 11 to move, and after reaching the designated place, remove the foot from the fireproof foot cover. The cover 11 can be taken out to be folded and the cover bottom 2 can be placed on the ground. There is no need for firefighters to get out of the protective cover to drive the protective cover to move together, which greatly improves the speed of movement in special situations.

In further detail, a plurality of air holes 12 are evenly opened at the bottom of the cover body 1, the harmful gas generated by the fire is generally in the upper part, and the flame will actually fly to the sky, and the temperature above will be higher, at this time, the air below contains There are fewer harmful gases, preventing firefighters from being in danger due to excessive carbon dioxide concentration in the protective cover for a long time.

In further detail, the fireproof foot cover 11 is made of aluminized coating flame retardant composite fabric, the surface is covered with aluminized reflective film, and the inner lining is cotton fiber, which improves the safety of firefighters when moving through the fireproof foot cover 11 and steps on high temperature. The place also has high temperature resistance for a long time.
