Abstract

The invention relates to a multi-buffering energy storage device and application thereof. The multi-buffering energy storage device comprises an energy storage cylinder, an oil tank, a first volute spring mechanism, a second volute spring mechanism, a hydraulic motor, a differential planetary gear train and a generator; the energy storage cylinder comprises a closed cylinder body, an elastic moving device is arranged at one end of the closed cylinder body, an energy transmitting device is arranged at the other end of the closed cylinder body, and hydraulic oil fills the space between the elastic moving device and the energy transmitting device; and the closed cylinder body, the hydraulic motor and the oil tank are connected through an oil way to form a hydraulic loop, the energy transmitting device is connected with the first volute spring mechanism, the hydraulic motor is connected with the second volute spring mechanism, and the first volute spring mechanism and the second volute spring mechanism are connected with the generator through the differential planetary gear train. According to the multi-buffering energy storage device, by means of the energy storage cylinder, redundant energy can be converted and stored, energy waste is reduced, and resources are saved. The energy storage device is ingenious in structural design, convenient to install and use, and high in energy conversion rate and storage rate.

Description

technical field [0001] The invention relates to a multiple buffer energy storage device and its application, belonging to the technical field of energy conversion and reuse. Background technique [0002] At present, the common accumulators according to the loading method can be divided into spring type, weight type, and gas type. The energy storage form of the above-mentioned accumulators is single, and the energy is not stored for further use. [0003] For example, Chinese patent document CN204037271U discloses an energy-recoverable oil-pneumatic suspension, including a hydraulic cylinder, an accumulator, a pipeline, a rodless chamber connected to the hydraulic cylinder, and the accumulator; the hydraulic motor is arranged in the pipeline, and the generator Connected with hydraulic motor transmission. The suspension system of the present application adds a controllable energy recovery device to the energy recovery oil-air suspension, has the function of energy recovery, an...
