AI Technical Summary

Technical Problem

Existing fire-fighting diesel internal combustion engines are inadequate in terms of earthquake resistance, fuel purification, and fuel tank pressure regulation, making it difficult to cope with complex disaster conditions such as earthquakes, resulting in shortened equipment lifespan and low automation.

Method used

The system employs a combination structure of a damping telescopic rod and a first spring for multi-stage buffering and energy absorption. Combined with the inclined baffle and filtration mechanism inside the oil tank, it achieves oil-water separation. The system utilizes the vibration force of the unit to drive automatic circulation separation and purification. It is equipped with a pressure balancing component to prevent negative pressure in the oil tank and the entry of humid air.

Benefits of technology

It achieves fully automated coordinated operation of equipment in fire emergency situations, including seismic stability, automatic oil-water separation and purification, and pressure balance, reducing maintenance costs and ensuring equipment availability and operational reliability at all times.

Abstract

This invention discloses an earthquake-resistant fire-fighting diesel generator set, relating to the technical field of diesel generator sets. It includes a diesel engine body mounted on top of a generator body, with the diesel engine body internally connected to the generator body via a transmission connection. A water tank radiator is located on one side of the generator body and communicates with the interior of the diesel engine body. This earthquake-resistant fire-fighting diesel generator set absorbs most of the vibration force generated during operation through a damping telescopic rod and a first spring in the base mechanism. Simultaneously, the remaining vibration force drives a lifting plate to move a first piston up and down within a pressure chamber, forming a unidirectional suction effect that continuously transports the oil-water mixture in the tank to a sedimentation tank for oil-water separation. The settled water remains at the bottom of the sedimentation tank, while the filtered oil automatically flows back to the tank. This achieves fully automatic coordinated operation of oil-water separation, filtration, and pressure balance while ensuring shock absorption.
