Emergency protective device of operation in confined space

Abstract

The invention provides an emergency protective device of operation in confined space. The emergency protective device of operation in the confined space includes a positive pressure type equipment helmet, a gas bomb, a gas delivery conduit, a reducing valve and an air valve. The positive pressure type equipment helmet includes a positive pressure type equipment helmet shell, a face mask, an air detector, a face mask opening and closing device, a gas delivery conduit interface and a control chip, wherein the front of the helmet shell is mechanically connected with the face mask, the opening andclosing device is fixed on the joint of the face mask and the helmet shell, and the control chip is electrically connected with the face mask opening and closing device, the automatic reducing valveof the gas bomb and the air valve. A gas delivery conduit interface is connected with the gas bomb through the gas delivery conduit, air / oxygen in the gas bomb enters into the helmet through the gas delivery conduit. The preparing time for construction work can be effectively reduced by the emergency protective device, workers can be timely and effectively protected in the confined space, and thusinjury by falling objects, hypoxia poisoning and other situations can be avoided, and the risk of construction can be reduced.

Description

technical field [0001] The invention relates to the technical field of emergency rescue equipment, in particular to an emergency protection device for working in a limited space. Background technique [0002] Emergency escape equipment is used for personnel escape in poisonous, harmful gas, smog and anoxic environment, mainly used in petroleum, metallurgy, chemical industry, ship, hotel, hotel computer room and entertainment place, and also suitable for other hazardous spaces. The existing limited space operation adopts the principle of "test first, then work". Without detection, operators are strictly prohibited from entering the confined space. [0003] In practical applications, the operating environment conditions in limited spaces may change, and continuous or regular detection of hazards in the workplace should be carried out. The equipment that personnel must carry when entering a limited space to work includes ventilation equipment, testing equipment, communication ...

AI Technical Summary

Problems solved by technology

[0005] The shortcoming of the limited space emergency rescue equipment in the above-mentioned prior art is: the long-tube mask-type equipment inhales filtered fresh air with the help of the human lungs to protect the safety protection equipment of the human respiratory system. Inconvenience to work

Positive pressure equipment requires manual control. In the case of changes in the confined space environment or unexpected situations, there may be insufficient reaction time to cause accidental personal injury.

Operators also need to wear safety helmets and testing equipment, and the preparation work is cumbersome
