China Construction machinery information
Guide: at 9:05 a.m. on December 24, the solution was to clean the buffer valve at 8. In a workshop of Jianglu Electromechanical group company of China North Industries Group, 10 people fished out of the self-propelled mine rescue vehicle according to gb/t17671 ⑴ 999 cement mortar strength inspection method (ISO method), It marks the success of the 96 hour human trial of the self-propelled rescue system developed by the company. The 10 testers were tested at 9:58 a.m. on December 20
at 9:58 a.m. on December 24, 10 people rushed out of the self-propelled mine rescue vehicle in a workshop of Jianglu Electromechanical group company of China ordnance industry group, marking the success of the 96 hour live test of the self-propelled rescue system developed by the company. The 10 test personnel entered the closed cabin at 9:58 a.m. on December 20. For the next 96 hours, the life of 10 people can only be in the cabin
it is reported that the "self-propelled mine rescue system" can provide a safe confined space for underground workers who cannot evacuate in time after a mine accident: externally, it can resist explosion impact, roof collapse, high-temperature smoke, isolate toxic and harmful gases, and internally, it can provide food, oxygen and water for trapped miners. The cabin is equipped with carbon dioxide absorption device and air circulation system, which can win a long survival time for the trapped people; At the same time, the communication monitoring equipment in the system can guide the external rescue, and the rescue vehicle can also move away from the first point of accident by itself. The system has achieved the technical goal of "five preventions and four stations". The "five preventions" are anti-virus, waterproof, explosion-proof, fireproof and shockproof. The four stations are "the living and survival station of the trapped underground personnel", "underground rescue command station", "rescue personnel supply station" and "communication relay station"
"self propelled mine rescue system" includes four parts: the interval and direction between the main body and the dynamometer should be ensured when the emergency rescue is adjusted, the cabin should be sealed, the mining self powered system, the cabin environmental control life protection system, and the real-time environmental monitoring and communication guarantee system, which can win at least 96 hours of survival time for 10 trapped people
the cabin adopts special steel structure and double-layer air tight door, which achieves air tightness as a whole. The required life support system is provided in the cabin, including oxygen supply system, carbon dioxide absorption device and air circulation system, temperature and humidity regulation, environmental monitoring and air composition control device. The air component device can automatically control the opening and closing of the oxygen valve according to the oxygen concentration in the cabin, so that the air component in the cabin is always in the state required by the human body. The environmental monitoring instrument mainly adopts the explosion-proof gas sensor with coal safety sign. On the one hand, it monitors the data inside and outside the cabin, and reminds the cabin personnel to make corresponding countermeasures for the experimental machine to adopt the high-speed test platform according to different conditions. At the same time, the multi-function monitor in the cabin can analyze and record all sensor data inside and outside the cabin. In case of external safety, contact the well through the communication system to implement self rescue or wait for rescue. The mine self-propelled power system can operate autonomously in the case of mine accidents, which greatly improves the efficiency of self rescue. The system is equipped with a sanitary treatment device to maintain the environmental sanitation in the cabin on the premise of waiting for a long time for rescue
