Abstract

The invention discloses a diesel engine safety protection device. The diesel engine safety protection device comprises an intermediate gear assembly, a bevel gear assembly, a galloping protection device component, an electromagnetic shutdown protection component and a shutdown mechanism component. The rotating speed of a diesel engine is transmitted to the bevel gear assembly through the intermediate gear assembly. The input rotating speed is sent to a speed governor through the bevel gear assembly. The speed governor controls the shutdown mechanism component to adjust an accelerator pull rod of the diesel engine. The rotating speed is transmitted to the galloping protection device component through the intermediate gear assembly. When the rotating speed of the diesel engine is larger than the galloping protection rotating speed threshold value, the output end of the galloping protection device component drives a third rocker arm to rotate through a stop block, and the third rocker arm controls the shutdown mechanism component to adjust the accelerator pull rod. The electromagnetic shutdown protection component is connected with the third rocker arm and capable of driving the third rocker arm to rotate through energizing remote control or manual control, and the third rocker arm controls the shutdown mechanism component to adjust the accelerator pull rod. The diesel engine safety protection device has the functions of speed governing transmission assisting, overspeed protection, emergency shutdown and the like.

Description

technical field [0001] The invention belongs to diesel engines, in particular to a diesel engine safety protection device. Background technique [0002] The hydraulic governor is used as a speed control mechanism of the diesel engine. Control the fuel supply of the diesel engine to always adapt to the external load, so as to ensure the stable operation of the diesel engine. Generally, the hydraulic governor is installed on the diesel engine through an additional gear transmission device, which assists in transmitting the speed of the diesel engine to the governor, so that the governor can control the fuel supply of the diesel engine according to the transmitted speed. [0003] When the speed of the diesel engine is out of control, a runaway will occur, which will cause serious damage to the diesel engine itself. In order to avoid the overrun of the diesel engine, the general diesel engine needs to have an overspeed protection function. At the same time, when the diesel en...
