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.

Embodiment 1

[0036] figure 1 A structural schematic diagram of a diesel engine scavenging air box fire extinguishing device provided by an embodiment of the present invention is shown. Such as figure 1 As shown, the diesel engine scavenging air box fire extinguishing device includes a detection device 10 , a control device 11 and an execution device 12 . Wherein the detection equipment is connected with the control equipment, is arranged inside the scavenging air box of the diesel engine, and sends the detection signal to the control equipment to detect whether a fire occurs in the scavenging air box. The control device is connected with the execution device through the driving circuit 13, receives the detection signal, and sends an execution instruction to the execution device, so that the execution device performs the temperature-lowering and fire-extinguishing operation.

[0037] The above-mentioned control device may be a single-chip microcomputer or a programmable controller PLC (Pr...

Embodiment 2

[0061] image 3 A schematic structural view of a diesel engine scavenging air box fire extinguishing system provided by an embodiment of the present invention is shown. Such as image 3 As shown, the diesel engine scavenging box fire extinguishing system includes a steam device 100, a CO device 200 and a diesel engine scavenging box fire extinguishing device 300 as in Embodiment 1; the steam solenoid valve of the diesel engine scavenging box fire extinguishing device is arranged at the outlet of the steam device , the CO of the diesel engine scavenging box fire extinguishing device 2 Solenoid valve set at CO 2 outlet of the device. Outlet of steam plant and CO 2 The outlets of the device are all connected to each scavenging air box in the diesel engine, and correspond to each scavenging air box one by one. In this way, the deceleration of the diesel engine can be controlled, and by controlling the corresponding CO 2 Solenoid valve and steam solenoid valve can input CO fo...

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...
