Abstract

The embodiment of the invention discloses a device and a fire prevention method. The device comprises a device body, an air inlet, an air outlet, an inlet air temperature detecting device, a control center, an air inlet control device and a cooling air channel, wherein the air inlet and the air outlet are arranged on the device body; the inlet air temperature detecting device is positioned at the air inlet of the device body and used for detecting the temperature value of an air flow entering the device body from the air inlet and sending the temperature value to the control center; the control center is used for judging the temperature value, and sending a shutdown signal to the air inlet control device when the temperature value is larger than a threshold value; the air inlet control device is used for shutting down the air inlet and the air outlet of the device body according to the shutdown signal; and the cooling air channel is positioned at the air inlet of the device body and used for cooling external high-temperature gas and / or flame in a fire disaster when the external high-temperature gas and / or flame enters the device body through the cooling air channel. Due to the active fire prevention design, the fire disaster outside the device can be detected automatically, so that the damage on the equipment caused by the external fire disaster can be avoided.

Description

technical field [0001] The invention relates to the field of fire prevention, in particular to a device and a fire prevention method. Background technique [0002] All types of equipment, especially those left unattended in the wild or in remote areas, are sometimes exposed to external fire hazards. Existing fire protection design schemes are usually passive fire protection schemes, that is, using fireproof materials as equipment casings or using heat insulating materials inside the equipment casings to resist high-temperature baking, so as to achieve heat insulation and prevent equipment casings from igniting and becoming a source of combustion. [0003] In the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages: [0004] When designing the casing of the device, it is generally necessary to consider the heat dissipation function. Therefore, the convection design of the air in and out is used on the casi...
