Automatic protection device of anti-explosive diesel engine

Abstract

The invention discloses an automatic protection device of anti-explosive diesel engine. The automatic protection device comprises an infrared temperature measurement device, a water coolant temperature sensor, a water coolant level sensor, an air exhaust temperature sensor, an engine oil pressure sensor, a combustible gas detector, an electronic control unit (ECU), a fuel oil shutoff valve and an automatic fire extinguishing device, wherein the infrared temperature measurement device, the water coolant temperature sensor, the water coolant level sensor, the air exhaust temperature sensor, the engine oil pressure sensor and the combustible gas detector are connected with the ECU through a bus. By the automatic protection device, the surface temperature, the air exhaust temperature, the water coolant temperature and level, the engine oil pressure, and the combustible gas content in an environment can be monitored in real time; and when the monitoring parameter exceeds a limit value, an alarm can be automatically sounded, and protective measures can be taken; and therefore, accidents can be prevented.

Description

technical field [0001] The invention relates to the field of explosion-proof diesel engines, in particular to an automatic protection device for explosion-proof diesel engines. Background technique [0002] At present, explosion-proof diesel engines are widely used because of their good safety performance in power equipment working in environments containing flammable and explosive gases such as mines. When an explosion-proof diesel engine works in an environment containing flammable and explosive gases, the surface temperature of the diesel engine, exhaust temperature, cooling water temperature and water level, oil pressure, and flammable gas content in the working environment are all required to be limited within a certain range. , may ignite combustible gases in the environment and cause accidents. Therefore, during the use of explosion-proof diesel engines, the above parameters must be monitored at all times, and when abnormal conditions occur, protective measures can b...

AI Technical Summary

Problems solved by technology

[0003] The existing automatic protection devices for explosion-proof diesel engines have the following problems: first, when detecting the surface temperature of the diesel engine, only a few limited positions are detected, which cannot reflect the overall situation of the outer surface of the diesel engine; Thirdly, when an abnormality occurs, there is no effective fuel cut-off and automatic fire extinguishing function

[0004] To sum up, the existing automatic protection devices for explosion-proof diesel engines have single function, low degree of automation, and low safety factor. These factors restrict the promotion and application of explosion-proof diesel engines
