Hydraulic power generation system and fire fighting truck with hydraulic power generation system

Abstract

The invention discloses a hydraulic power generation system. The hydraulic power generation system comprises a hydraulic power generation unit (1) and a control unit (2), wherein the hydraulic power generation unit (1) is used for converting hydraulic power into electric energy; hydraulic power is connected with the hydraulic power generation unit (1), the control unit (2) controls the hydraulic power to drive or stop work of the hydraulic power generation unit (1), and an opening P of the control unit (2) is connected with an oil inlet of the hydraulic power to control hydraulic oil to flow into or stop entering the opening P of the hydraulic power generation unit (2). The control unit (2) is composed of an electromagnetic directional valve (2-1), a throttling valve (2-2) and an overflow valve (2-3). The invention further discloses a fire fighting truck with the hydraulic power generation system. The hydraulic power of the fire fighting truck is connected to the hydraulic power generation unit through the control unit, so that the hydraulic power of the fire fighting truck is converted into electric energy to be used by the fire fighting truck. The hydraulic power generation system has the advantages that a power source is used conveniently and efficiently, the power density is large, the rescuing time is saved, and the rescuing efficiency is improved.

Description

technical field [0001] The invention relates to a power generation system for a fire truck, in particular to a hydraulic generator system and a fire truck using the system. Background technique [0002] During the fire rescue process, equipment such as lighting and electric tools are essential. Under normal circumstances, most of the power systems at the rescue site have been damaged, and equipment that requires electricity such as lighting and electric tools cannot be used, hindering many rescue efforts and seriously delaying rescue time. [0003] Existing emergency rescue fire engines are mostly equipped with gasoline generators, but gasoline generators are large, heavy, and have low power density, which cannot meet the needs of on-site rescue. [0004] It generally includes two types, one is directly fixed on the fire truck, which needs to occupy a large space of the fire truck when it is designed and arranged, and it is also inconvenient to use. [0005] There is als...

AI Technical Summary

Problems solved by technology

Under normal circumstances, most of the power systems at the rescue site have been damaged, and lighting, electric tools and other electric-driven equipment cannot be used, hindering many rescue work and seriously delaying rescue time

[0003] Existing emergency rescue fire trucks are mostly equipped with gasoline generators, but gasoline generators are large, heavy, and have low power density, which cannot meet the needs of on-site rescue

[0004] It generally includes two types, one is directly fixed on the fire truck, which takes up a lot of space in the fire truck when it is designed and arranged, and it is inconvenient to use

[0005] There is also a gasoline generator that can be moved, and rollers are set at the bottom of the generator. When in use, the generator should be placed on a level ground and the rollers should be fixed; if no rollers are installed, it will bring a lot of inconvenience to the replacement of gasoline.

[0006] To sum up: From the perspective of the urgency of rescue, there is not much time to adjust the position of the generator, which will affect the efficiency of rescue
