Technical Field

The invention relates to the technical field of emergency rescue in special industries, in particular to a cooling device for a platform for emergency repair in a dangerous scene.

Background

Most insulating media of the electrical equipment used at present are SF6 gas, SF6 gas can be leaked when the electrical equipment explodes or catches fire in a high-voltage switch chamber, and meanwhile, a large amount of toxic gases such as smoke, carbon monoxide and chlorine are often generated along with the leakage. The breakdown of an insulating medium is generally caused by the fault of the electrical equipment, and the fault of single-phase grounding is difficult to find in many cases. At the same time, the secondary wire, the housing, and the like may be charged. After the electrical equipment breaks down, the secondary power supply from the voltage transformer is possibly disconnected, illumination can only be realized by a field emergency lamp, and severe factors such as field smoke and the like are added, so that emergency personnel cannot enter a switch room to watch and judge the accident situation. Thus, emergency personnel typically enter the respirator or respirator through a window or after wearing the respirator or respirator, or after exhausting sufficiently. But this takes a long time and even misses the best time for accident handling, resulting in further spread of the accident.

Application No.: CN201810076371.6, the invention of the invention discloses a liquid carbon dioxide cooling fire prevention and extinguishing system, a liquid carbon dioxide tanker vehicle outputs liquid carbon dioxide from a metal hose into a liquid carbon dioxide pipe, the liquid carbon dioxide flows into the high-pressure seamless liquid carbon dioxide pipe from a ground liquid carbon dioxide control valve through the liquid carbon dioxide pipe, a temperature sensor of a mining conveying area and a goaf pressure sensor located in a goaf remove the temperature and pressure of the carbon dioxide in the goaf, a PLC control system starts a liquid carbon dioxide gasification device, the liquid carbon dioxide gasification device conveys the liquid carbon dioxide to a vaporizer set, the liquid carbon dioxide vaporizes and absorbs heat, cold air is conveyed to a working surface through a fan to reduce the temperature of the working surface, the liquid inlet end and the gas outlet end of the liquid carbon dioxide gasification device both adopt sensors to collect data, the PLC control system controls the opening of the valve according to the data collected by the sensors, thereby solving the problem that the liquid carbon dioxide device can not be accurately adjusted.

However, such a carbon dioxide cooling device is an internal circulation device, and needs to be installed in the equipment in advance at the time of manufacturing the equipment. And cannot interact with the environment to perform the operations of extinguishing fire and removing toxic gases, except for cooling. The carbon dioxide flow rate of circulation is limited in the cooling pipe, and the cooling effect is relevant with the pipe diameter, but too big pipe diameter leads to rescue platform volume and quality too big in some critical scenes, influences the effect of speedily carrying out rescue work on the contrary.
