Within the vehicle, there are hygiene emergency treatment 0 devices, oxygen storage, carbon dioxide absorber, food, drinking water, power source, devices for observing outside environment from the vehicle, communication devices and etc. The electric emergency rescue vehicle is equipment capable of coping with all kinds of disasters, ensuring workers' safety and for reducing the loss of properties when a disaster occurs in coal mine. Its 5 character is: the body of the electric emergency rescue vehicle is able to act as a sealed capsule. It's a drivable vehicle under disaster conditions, such as a water disaster, fire disaster, coal dust and gas explosion or in an environment where a tunnel is filled with harmful gas and without oxygen. It can carry the workers to safety, transport the sick and wounded, and transport rescue workers and supervisors to the disaster site rapidly. It can supply all kinds of disaster relief and supply materials to .0 a disaster area. It can also be used as an ambulance, exploration vehicle, emergency car, rescue car, refuge car, transfer car, waiting car and rescue command car. The electric power source of the vehicle is a rechargeable storage battery and is located near the bottom of the vehicle, so that the battery is in an airtight state, ensuring that there is no leakage of 25 electricity, no short circuit and no broken circuit when submerged in water. As the position of the battery is near the bottom of the device, the vehicle offers a large space inside the vehicle. The vehicle can be driven using the storage battery. The lighting, audio and video intercom, communication device, fan and the instrument for observing the environment parameter are powered by direct current. 30 The surface of the vehicle is anti-fire, pressure-resistant and anti-impact metal structure. Its internal and external surfaces are applied with a coat of material which endures high temperature, anti-fire, anti-heat and anti-radiation. The upper part of the vehicle is a semicircle and the lower part is rectangular. The whole body is elongated. The inside and outside of both ends have lightings, audio and visual intercom, bulletproof observation screen and a microphone. The middle and upper part, 35 inside and outside of the vehicle may include bulletproof glass which can withstand high temperature. Doors at each end open outwards. After closing the vehicle doors, they are water and air proof. Above the vehicle doors there are three steel tubes with valve. The aim is to receive underground air pressure, 4 air circulation and to act as a safety valve, so that it can ensure that pressure on the vehicle is not over 0.15Mpa. Near the inner side of the doors of the electric emergency rescue vehicle, there are operating and 5 control devices. Below the operating and control devices is the seat of the driver. The top inner side of the vehicle includes two lamps for lighting. In each side of the device set, there are rectangle metal chairs which are side by side. The length of the chairs is 6-8m, width 0.3m and height 0.4m within the effective space inside the vehicle. One side under the seat includes ice storing devices and calcium hydroxide filter stick, used to adjust temperature and air composition inside the vehicle. The other side 0 includes a food box, pressured oxygen, chemical oxygen generating machine and oxygen generating medical items, and emergency treatment devices. It is also possible to include a toilet. The space inside the electric emergency rescue vehicle is large. It can take more people, transport a number of rescue goods and materials, resist explosion, large impact wave and high temperature. The 5 capacity of the battery is large. The vehicle is good in dragging and climbing motions. It is easy to operate, convenient to speed up, slow down and stop. It can move in water and also move in a tunnel filled with harmful gas and without oxygen. It can avoid a disaster area rapidly. It can transport materials to disaster area rapidly. It also can carry wounded people out of a dangerous area, otherwise it can be resting place for emergency rescue workers, be a commanding place for rescue commanders .0 to analyse the disaster area and give directions to rescue workers. In certain conditions, it can be a transfer station. In one embodiment, two ends of the electric emergency rescue vehicle include seats of drivers. It can be driven rapidly. It uses a single power engine. It can be controlled by a double electric circuit. It can 25 be driven directly. At the same time, the double electric circuit can be a self-cutting electric circuit.
