Kinetic energy recovery device and drainage system

Abstract

The invention belongs to the technical field of municipal drainage, and particularly relates to a kinetic energy recovery device and a drainage system. The kinetic energy recovery device comprises a first piston cylinder vertically arranged under a pavement speed bump, wherein a first gas port and a second gas port are formed in a piston upper-side cavity of the first piston cylinder; the first gas port communicates with a negative pressure tank through a pipeline; the second gas port communicates with the atmosphere; a first one-way valve is arranged on the first gas port; and a second one-way valve is arranged on the second gas port. According to the kinetic energy recovery device and the drainage system provided by the invention, the kinetic energy recovery device arranged under the speed bump is utilized for recovering and temporarily storing automobile kinetic energy into an energy storage device, and the energy storage device can provide a continuous suction force for a suction device, so that the suction device can suck and drain accumulative water of a low-lying road segment into a municipal drainage network. According to the kinetic energy recovery device and the drainagesystem provided by the invention, no any energy supply equipment needs to be externally connected, a simple and high-efficiency pavement drainage solution is provided, and meanwhile, a braking force of a car can be recovered and utilized, so that a great environmental protection significance is realized.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and in particular relates to a kinetic energy recovery device and a drainage system. Background technique [0002] With the continuous expansion of the city, more and more intersections have begun to build three-dimensional transportation facilities such as elevated and underpass to improve the efficiency of road traffic. With the reconstruction of these roads, the urban drainage system must also be upgraded accordingly. However, it is often difficult to predict the future development trend of urban construction in the early urban drainage networks when they are built, so they are generally set at a shallow position from the ground during construction. The height of the original urban drainage network, therefore, in order to connect the drainage system of the underpassing section to the original urban drainage network, it is necessary to set up water conservancy facilities such as pump...

AI Technical Summary

Problems solved by technology

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
