[0031] According to the above structure, when the device is used for forest tree fire prevention monitoring, first, the reinforced cylinder 1 and the extension cylinder 2 are installed near the tree in the open area by the support, so that when a fire occurs, the high-temperature airflow is transported into the heat insulation cover 10, the air in the heat insulation cover 10 is heated and the density is reduced to generate buoyancy and expansion without interference, and at the same time, multiple devices can be installed in the forest according to the distribution of trees.

[0032] And when a fire occurs during use, the temperature sensor 4 first detects the temperature, and the temperature sensor 4 transmits the data to the buzzer 19 to make the buzzer 19 send an alarm and notify the control personnel, and in order to ensure the accuracy of fire monitoring, the fan 17 runs to extract the high-temperature airflow generated when the fire occurs into the gas collecting head 25, and the high-temperature airflow is gathered by the gas collecting head 25 and then transported into the shunt disc 5 through the first heat preservation pipe 12, and then through the extension pipe 14, the joint 24 and the gas collecting head 25 through the nozzle 15, the air inside the heat insulation cover 10 is heated and the density is reduced to generate buoyancy and make the heat insulation cover 10 expand upward at the same time, and when the heat insulation cover 10 rises upward, the inductor 8 is driven by the pull rod 11 to displace, the grating displacement sensor 7 senses the position of the inductor 8 and alarms through the buzzer 19, and through the heat insulation cover 10 rising in the forest fire scene, the hot air is quickly deployed to send a help signal at a high altitude, so that the staff can quickly respond;

[0033] And the high-temperature airflow is gathered by the gas collecting head 28, and the filter plate 18 can filter the floating impurities in the high-temperature airflow, and by continuously supplying enough high-temperature airflow, the heat radiation and convection heat dissipation of the heat insulation cover 10 are offset, and the tin foil heat preservation strip 27 reduces the loss speed of the high-temperature airflow transported into the heat insulation cover 10, so as to make the heat insulation cover 10 rise, ensure the accuracy of fire monitoring, and then the heat insulation cover 10 and the inductor 8 are reset after the subsequent fire fighting is completed, so as to continuously use the device.

[0034] Different from the prior art, the application discloses a fireproof monitoring device. High-temperature gas flows out through the nozzle 15 through the extension pipe 14, the joint 24 and the gas collecting head 25. The air in the temperature insulation cover 10 is heated and its density is reduced to generate buoyancy, and the temperature insulation cover 10 is expanded and rises up at the same time. When the temperature insulation cover 10 rises up, the inductor 8 is displaced through the pull rod 11. The grating displacement sensor 7 senses the position of the inductor 8 and alarms through the buzzer 19. The temperature insulation cover 10 rises in the forest fire scene, and a high-altitude rescue signal is quickly deployed by using hot gas, so that the staff can quickly respond. The filter plate 18 can filter the floating dust impurities in the high-temperature gas flow. By continuously supplementing the high-temperature gas flow, the heat radiation and convection heat dissipation of the temperature insulation cover 10 to the outside are offset. The tin foil heat preservation strip 27 reduces the loss speed of the high-temperature gas flow delivered to the temperature insulation cover 10, so that the temperature insulation cover 10 rises, and the fire monitoring accuracy is ensured. After the subsequent fire fighting is completed, the temperature insulation cover 10 and the inductor 8 are reset, so that the device can be continuously used.
