Energy-storing and energy-releasing assembling type road slab used for large longitudinal slop

Abstract

The invention discloses an energy-storing and energy-releasing assembling type road slab used for a large longitudinal slope. The road slab is formed by splicing a plurality of road units, wherein each road unit comprises a controller, a firs assembling unit, a second assembling unit, a movable panel and a speed sensor used for detecting speed of a vehicle on a road; one end of the movable panel is connected with the side surface at the top of the second assembling unit, the other end of the movable panel covers and is fixed above an opening in the top of the first assembling unit, the first assembling unit can move up and down, an energy storage system used for storing and releasing potential energy produced by the first assembling unit when moves downward is arranged in the first assembling unit, an output terminal of the speed sensor is connected with an input terminal of the controller, and an output terminal of the controller is connected with an input terminal of the energy storage system. The assembling type road slab disclosed by the invention has the advantages that kinetic energy of the vehicle when travels downhill can be absorbed, speed of the vehicle when travels downhill is reduced, and the vehicle can be assisted to speed up when climbs up a hill, so that energy consumption of the vehicle is reduced.

Description

technical field [0001] The invention belongs to the field of road surface energy storage and conversion utilization, and relates to an assembled road slab used for energy storage and release on long longitudinal slopes. Background technique [0002] The long longitudinal slope section we are talking about refers to: when the average longitudinal slope is 3%, the continuous downhill slope is longer than 5km; when the average longitudinal slope is 4%, the continuous downhill slope is longer than 4km; when the average longitudinal slope is 5%, The continuous downhill slope is longer than 3km. Accident-prone road sections with long longitudinal slopes account for 55% of the total road sections, especially traffic accidents caused by speeding on long downhill sections account for 40%. The safety problems faced are more prominent and the situation is extremely severe. [0003] On a section with a long longitudinal slope, when the vehicle climbs the slope, the speed decreases, the...

Problems solved by technology

[0006] However, the climbing lane and the emergency lane need to be specially set up separately, which occupies more land resources, does not use the energy of the vehicle to solve the problem of the existing long longitudinal slope section, and the power performance, fuel consumption, and gradient of large vehicles on various longitudinal slopes. There is a lack of demonstration and analysis of slope length restrictions, which affects the efficiency of road transportation
