Abstract

The invention belongs to the field of safety protection of a coal bed gas drilling machine, and relates to a safety protection system, in particular to a safety protection system for a coal bed gas drilling machine engine. The system is provided with a combustible gas sensor, a poisonous gas sensor, a rotating speed sensor, an acousto-optic alarm lamp, a controller, a scram switch and an electromagnetic turn-off valve. The combustible gas sensor and the poisonous gas sensor are installed at the portion of a vehicle-mounted drilling machine construction orifice, and the rotating speed sensor is installed on a flywheel of the engine or an electricity generator; after the electromagnetic turn-off valve is installed on an engine air filter, the controller, the acoustic-optic alarm lamp and the scram switch are integrated together and installed on a drilling machine control console, and all the components are communicated through a circuit. According to the safety protection system, the purpose of safety protection of an engine in the coal bed gas exploitation and development process can be achieved, prejudgment protection, emergent turn-off and safety shutdown of risk working conditions of the engine can be achieved, and therefore equipment and personnel safety can be guaranteed.

Description

technical field [0001] The invention relates to a safety protection system and method, which belongs to the field of safety protection of a coalbed methane drilling rig, and in particular to a safety protection system and method for a coalbed methane drilling rig engine. Background technique [0002] The drilling rig is the main equipment in the process of coalbed methane exploration and development, and the importance of the industrial engine as the power source of the drilling rig is self-evident. During the operation of the engine, it will encounter working conditions such as abnormal operation, external equipment failure, and dangerous environment. The hazardous environment mainly refers to the combustible and toxic gases that are produced during the exploration and development of coalbed methane. The combustible gas enters the combustion chamber of the engine through the engine air intake system and is used for uncontrolled fuel of the engine, which causes the engine t...
