A hydraulically driven renewable energy vehicle energy recovery and utilization device and energy vehicle

Abstract

The invention discloses a renewable energy vehicle recovering and utilizing device hydraulically driven and an energy vehicle. The renewable energy vehicle recovering and utilizing device comprises metering pumps, a variable motor, a two-position three-way reversing valve, a three-position four-way reversing valve, a two-stage energy accumulator, a plurality of one-way valves used for controlling conduction of oil liquid and an oil tank storing oil liquid. A pump-controlled motor hydraulic system is used for driving a load, and the loss in the energy transmitting process is reduced to be minimal. Switching of serial and parallel work modes of two pneumatic hydraulic pumps can be achieved by switching the two-position three-way reversing valve in good time, and therefore the renewable energy vehicle recovering and utilizing device can better adapt to the work condition environment of the low wind speed and high wind speed. The two-stage energy accumulator is used for enabling the energy storage link and the energy storage link to independent from each other, and the interference on the energy output due to the random factor in the energy recovering process is eliminated. The renewable energy vehicle with the hydraulic system is free of fuel and environment-friendly, the work is not limited by the wind speed or the wind direction, and the application is wide. The renewable energy vehicle recovering and utilizing device is suitable for medium-low load and medium-low speed light vehicles such as small ferry vehicles and sightseeing vehicles in the tourist attractions.

Description

technical field [0001] The invention belongs to the field of fluid pressure control mechanisms, and in particular relates to a hydraulically driven renewable energy vehicle energy recovery and utilization device and an energy vehicle. Background technique [0002] With the global energy crisis and environmental problems becoming more and more prominent, the development and utilization of renewable energy has become a hot spot pursued by countries all over the world. Wind energy and solar power generation have played an important role in the utilization of renewable energy in the past, bringing new development opportunities to the electric energy industry. However, the use of renewable energy for power generation will be limited by many factors, such as natural environmental factors such as wind power and site, and economic factors such as one-time large-scale investment. Therefore, broadening its application range is an effective way to further develop and utilize renewable...

Problems solved by technology

Since the wind speed and direction near the ground are variable, it is difficult to continuously supply energy, which affects the continuity of the power required for the vehicle to move forward. Therefore, the development of a wind energy recovery device suitable for different working conditions is the key to solving this type of application.

At the same time, there is a large randomness in the collection and storage of energy and the distribution of the power required to drive the load. Therefore, effective measures must be taken to eliminate the mutual interference between the two without affecting energy recovery and distribution.
