Description

technical field [0001] The invention relates to the technical field of road energy utilization, in particular to a road gas collection energy storage power generation device. Background technique [0002] With the change of climate and environment and the shortage of petroleum energy, the search for non-pollution renewable green energy has been highly concerned by people. There are a large number of renewable green energy in people's life. The collection and utilization of green energy is in line with the sustainable development of our society. development requirements. In the process of seeking new energy, roads, as an important infrastructure, have the potential to develop renewable energy while undertaking transportation functions. In recent years, with the development of micro-energy harvesting technology in road engineering, more types of advanced technologies have been used in the road environment. Energy harvesting research in the field of road engineering mainly inc...

Problems solved by technology

[0004] At present, power generation equipment mainly includes hydraulic transmission, gear mechanical transmission, electromagnetic power generation, air bag liquid bag energy storage power generation and other forms according to different principles. Considering the actual situation of traffic flow, the power generation process of hydraulic transmission and mechanical transmission mode is intermittent. , can not make the generator work continuously, which will lead to low energy conversion rate of the equipment

In order to reduce the loss in the process of energy conversion, the problems existing in the first two modes can be overcome by adopting energy storage power generation. The device still has some shortcomings in the collection part and the energy stable release part, which restricts the marketization of the product. The main shortcomings are:

[0005] 1) Only one long airbag is used to collect gas, and the amount of gas collected is limited, that is, the conversion rate of driving potential energy is not high;

[0006] 2) The airbag filling process is slow. If the vehicle passes continuously, the potential energy of the vehicle may not be collected in time;

[0007] 3) The output air pressure of the airbag is low, which will lead to low efficiency of the equipment as a whole;

[0008] 4) The airbag is easily damaged, has poor durability, and has a high frequency of replacement
