Low-lying road surface drainage system based on kinetic energy recovery

Abstract

The invention belongs to the technical field of municipal drainage, and particularly relates to a low-lying road surface drainage system based on kinetic energy recovery. The low-lying road surface drainage system comprises a speed bump arranged on the road surface and a kinetic energy recovery device arranged below the speed bump, the kinetic energy recovery device is connected to an energy storage device, the energy storage device is connected to a pumping device, one end of the pumping device is in communication with a low-lying road surface drainage passageway, and the other end of the pumping device is in communication with a city drainage network. According to the low-lying road drainage system, the kinetic energy recovery device arranged below the speed bump is used for recovering kinetic energy of cars and temporarily storing the energy in the energy storage device, the energy storage device can provide continuous pumping force for the pumping device, and therefore the pumpingdevice can pump accumulated water on a low-lying road section into the city drainage network; the low-lying road surface drainage system does not require to be externally connected with any energy supply equipment and is a simple and efficient road surface drainage solution; and meanwhile, the braking force of the cars can be recovered and utilized, and the low-lying road drainage system has greatenvironmental protection significance.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and in particular relates to a low-lying road surface drainage system based on kinetic energy recovery. Background technique [0002] With the continuous expansion of the city, more and more intersections have begun to build three-dimensional traffic facilities such as elevated roads and underpasses to improve road traffic efficiency. With the reconstruction of these roads, the urban drainage system must also be upgraded accordingly. However, it was often difficult to predict the future urban construction development trend when the early urban drainage network was constructed, so it was generally set at a shallower position from the ground when it was constructed, which has led to the fact that most of the underpass road sections today are lower than The height of the original urban drainage network, so if the drainage system of the underpass road section is connected to the original u...

However, it was often difficult to predict the future urban construction development trend when the early urban drainage network was constructed, so it was generally set at a shallower position from the ground when it was constructed, which has led to the fact that most of the underpass road sections today are lower than The height of the original urban drainage network, so if the drainage system of the underpass road section is connected to the original urban drainage network, water conservancy facilities such as pumping stations must be installed on these road sections

Existing pumping stations are mainly driven by electric energy, which not only has high construction costs, but also generates huge energy consumption. When encountering heavy rain, the efficiency of upgrading is often insufficient, which can easily lead to water accumulation on the road, resulting in huge loss of personnel and property
