Description

TECHNICAL FIELD

[0001] The utility model relates to elevator technical field, concretely relates to a new energy elevator's energy conversion device. BACKGROUND

[0002] In the design of modern elevators, the power supply scheme of elevator systems gradually turns to the direction of environmental protection, energy saving and high autonomy. In order to adapt to the development, the applicant has previously proposed a new energy elevator with application number 2025101172126. The elevator adopts double battery design and is connected with photovoltaic power supply device. It not only can ensure the stable operation of the elevator, but also reduces the dependence on commercial power and reduces carbon emissions through the utilization rate of photovoltaic power supply device, and improves the environmental protection of the system. However, the technical scheme does not recycle the kinetic energy generated during the descent of the elevator car, which causes resource waste.

[0003] The kinetic energy recovery structure disclosed in the current market for recovering the kinetic energy generated during the descent of the elevator car can refer to the technical scheme with application number 202320561536.5, which includes a base and a moving seat. The upper surface of the moving seat is fixed with a DC generator. The top end of the DC generator is fixed with a CVT gearbox matched with the DC generator. The input shaft of the CVT gearbox is fixedly connected with a pressure plate. The pressure plate is matched with a flywheel. The moving seat is controlled to move through a hydraulic telescopic rod. The upper surface of the base is fixed with a storage battery. The technical scheme drives the CVT gearbox connected with the pressure plate to rotate by using the friction force when the pressure plate is pressed on the surface of the flywheel. The CVT gearbox transmits power to the DC generator to generate electricity, realizing the recovery of kinetic energy during the descent of the elevator car.

[0004] However, the kinetic energy recovery structure disclosed in the technical scheme does not have pressure detection function. When the hydraulic telescopic rod controls the movement of the moving seat, the situation that the pressure plate is pressed and damaged by the flywheel due to excessive thrust may occur.
