Power generation and energy storage device based on underground rainwater pipe network

Abstract

The invention discloses a power generation and energy storage device based on an underground rainwater pipe network. The device comprises an energy storage device, a miniature hydraulic turbine generator and a catchment closing-in device; a catchment compression cavity is arranged at one end of the catchment closing-in device towards the water incoming direction, and the catchment compression cavity is of a structure with the inner diameter gradually shrunk along the water flow direction; the miniature hydraulic turbine generator is mounted in a water outlet of the catchment compression device; and a filter screen device is arranged at the inlet end of the catchment compression cavity and is of an inclined inwards-concave installation structure. The catchment closing-up device is arranged in a rainwater pipeline, so that the water flow speed can be increased, and the power generation efficiency is improved; and the inclined concave variable-gap filter screen device is arranged at the inlet of the catchment closing-up device, so that impurities can be automatically cleaned and filtered. Therefore, the labor cost, the storage battery replacement cost, the operation and maintenance device line reconstruction cost and the like can be effectively reduced, and the overall construction cost of urban operation and maintenance, especially underground rainwater pipe network monitoring, is reduced.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a power generation and energy storage device based on an underground rainwater pipe network. Background technique [0002] As the country vigorously promotes the construction of new cities and improves the level of urban intelligence, "one map" digital management of underground pipe networks and unified management of urban operations, a large number of sensors and intelligent terminals are used in the construction of smart cities. In order to solve the problem of urban waterlogging, a large number of intelligent sensing terminal devices will be deployed in key nodes of drainage facilities, rainwater pipe networks, and waterlogging points to meet daily management, operation scheduling, disaster prediction, early warning and forecasting, flood control scheduling, and emergency rescue. Wait. Among them, the energy supply mode of the intelligent sensing terminal equ...

Problems solved by technology

Although there are currently some technical solutions for installing power generation devices in underground rainwater pipe networks for power generation, these existing technical solutions generally have the problem that the design is not scientific and reasonable. Meet the needs of actual use; and there is still the problem that even if the filter device is installed, it is still easy to block the water inlet of the generator. It is often necessary to manually clean up the impurities intercepted by the filter device, which is not only time-consuming and laborious, but also further affects the power generation efficiency
