Diesel engine scavenging box fire extinguishing device and system

Abstract

The invention provides a diesel engine scavenging box fire extinguishing device and a system, which relate to the technical field of diesel engine detection and control. The diesel engine scavenging box fire extinguishing device comprises a detection device, a control device and an execution device; the detection device is arranged in a scavenging box of a diesel engine, is connected with the control device, and sends a detection signal to the control device so as to detect whether a fire breaks out in the scavenging box; the control device is connected with the execution device through a drive circuit, receives the detection signal and sends an execution command to the execution device; the execution device carries out fire prevention and fire extinguishment operation through releasing different fire extinguishing media. The fire can be automatically judged through the detection device, so that the breaking out of the fire can be prevented. After the breaking out of the fire is determined or a fire sign happens, the execution device is automatically controlled to cool and extinguish the fire, so that the time from fire determination to fire extinguishing execution is effectively shortened, the aims of timely discovering the fire and quickly eliminating the potential safety hazard are achieved, and the safe navigation of ships is further ensured.

Description

technical field [0001] The invention relates to the technical field of diesel engine detection, in particular to a diesel engine scavenging air box fire extinguishing device and system. Background technique [0002] The diesel engine is the main propulsion power unit of the ship, and its operation reliability is directly related to the navigation safety of the ship. Once the diesel engine fails, the whole ship will be paralyzed. Therefore, real-time monitoring of the marine diesel engine is of great significance. The marine diesel engine is located in the engine room of the ship, and the engine room is located at the lower part of the deck. Due to the poor ventilation and high temperature in the cabin, and the insufficient fuel combustion, it is easy to have high exhaust temperature, and the exhaust temperature is too high. The scavenging box and supercharger are caused to catch fire. When the ship is sailing in relatively bad sea conditions, the speed is very prone to insta...

Problems solved by technology

The marine diesel engine is located in the engine room of the ship, and the engine room is located at the lower part of the deck. Due to the poor ventilation and high temperature in the cabin, and the insufficient fuel combustion, it is easy to have high exhaust temperature, and the exhaust temperature is too high. Cause the scavenging box and supercharger to catch fire. When the ship is sailing in relatively bad sea conditions, the speed is prone to instability or even speeding, which seriously affects the safety of life and property.

[0003] The fire in the scavenging tank of modern large-scale diesel engines is a major problem that plagues the safe operation of diesel engines. At present, ship design, research and development and management personnel do not have a good way to prevent and solve this problem. They can only be taken after manual fire judgment. Manually open the steam fire extinguishing valve next to the scavenging box to extinguish the fire

It takes a long time to manually judge whether a fire has occurred and take fire-fighting actions, and there are certain safety hazards for those who take fire-fighting actions
