An energy-saving elevator

Abstract

The invention discloses an energy saving elevator. The energy saving elevator comprises a hoistway vertically arranged, a car arranged in the hoistway, a driving device for driving the car to move, and a power supply system, wherein the power supply system comprises a commercial power supply device and a solar power supply device; and the solar power supply device comprises a photovoltaic plate set. The energy saving elevator further comprises a rainwater detecting unit, a sunlight angle detecting unit, a rotary lifting mechanism and a deflecting mechanism; the deflecting mechanism and the photovoltaic plate set are in drive connection; the rotary lifting mechanism and the deflecting mechanism are in drive connection; an object carrying cavity is formed in the top of the hoistway; a door opening and closing mechanism is arranged at the top of the object carrying cavity; a lifting cylinder is fixed in the object carrying cavity; the rainwater detecting unit detects if it is raining, and controls the door opening and closing mechanism and the lifting cylinder to work; and the sunlight angle detecting unit detects the sunlight angle, and controls a rotating motor and a hydraulic oil cylinder to work to enable the photovoltaic plate set to be perpendicular to the sunlight.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an energy-saving elevator. Background technique [0002] As an essential tool for high-rise buildings, elevators are used more and more widely. However, the power consumption of elevators accounts for about 20% of the total power consumption, second only to the power consumption of air conditioners. Such a large power consumption of elevators does not meet the requirements. The national sustainable development policy leads to a large loss of energy and brings a large economic burden to users. In the prior art, solar energy is used in elevators, but the utilization rate of solar energy is low. On the basis of the high cost of solar energy, the effect of effective energy saving cannot be achieved, and the service life of solar power supply devices used in elevators is relatively short, so the current It is necessary to design an energy-saving elevator with high utilization rate of solar e...

However, the power consumption of elevators accounts for about 20% of the total power consumption, second only to the power consumption of air conditioners. Such a large power consumption of elevators does not meet the requirements. The national sustainable development policy leads to a large amount of energy loss and brings a large economic burden to users

In the prior art, solar energy is used in elevators, but the utilization rate of solar energy is low. On the basis of the high cost of solar energy, the effect of effective energy saving cannot be achieved, and the service life of solar power supply devices used in elevators is relatively short, so the current It is necessary to design an energy-saving elevator with high utilization rate of solar energy and long service life
