Reversible roof rainwater power generation and lift energy supply system

Abstract

The invention discloses a reversible roof rainwater power generation and lift energy supply system which comprises a lift car, pulley assemblies, speed limiters and a stay. A switch, external limit switches and a safety gear are arranged in the lift car, an upper pool with a rain collecting function is arranged on a roof of a building, and a lower pool with a water storage function is arranged at the bottom of the building; a water pipe is arranged between the upper pool and the lower pool, and the lower pool is provided with a reversible power generation and electric water pump; the reversible power generation and electric water pump can be simultaneously connected with a pump body and a rotary shaft of a sheave. The reversible roof rainwater power generation and lift energy supply system has the advantages that power can be generated by the aid of potential energy provided by the upper pool to drive the lift car to move upwardly, water stored in the lower pool can be lifted into the upper pool by power generated by the aid of downward movement potential energy of the lift car, accordingly, energy consumption can be reduced, a clean energy source can be provided, and the manufacturing cost of an energy-saving lift can be reduced; problems of shortage of supply water, high urban waterlogging stress and the like can be solved by a roof rainwater collecting system; rainwater is collected for power generation, so that a temporary power source can be provided under extreme weather conditions, and conditions can be provided for personnel transfer, escape and the like; the reversible roof rainwater power generation and lift energy supply system is provided with reservoirs, so that certain fire safety effects can be realized for the high-rise building.

Description

technical field [0001] The invention relates to energy utilization technology of urban high-rise buildings, in particular to a natural energy recovery and utilization system which uses high-rise buildings to store rainwater to generate electricity for use by elevators. Background technique [0002] With the rapid development of science and technology, new technologies and methods are gradually loved by the public due to their advantages of high efficiency, energy saving and environmental protection. However, in the field of elevators, most domestic elevators use traditional elevators. With the acceleration of urbanization, the number of elevators is bound to continue to increase. The huge energy consumption of elevators has attracted close attention from the social and government functional departments. The status quo of my country's energy presents new challenges. At present, the research on this pumped-storage elevator is still in its infancy at home and abroad, and the us...

However, in the field of elevators, most domestic elevators use traditional elevators. With the acceleration of urbanization, the number of elevators is bound to continue to increase. The huge energy consumption of elevators has attracted close attention from the social and government functional departments. my country's energy situation poses new challenges

At present, the research on this kind of pumped storage elevator is still in its infancy at home and abroad, and the use of water resources in the elevator field is still blank in the prior art.
