Title:
LEVELING DEVICE HAVING ENERGY RECOVERY FUNCTION, AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/051127
Kind Code:
A1
Abstract:
A leveling device having an energy recovery function, comprising a leveler (10) and an energy recovery device. The leveler (10) performs leveling by means of electromagnetic induction heating, and the energy recovery device collects wind energy generated during the operation of the leveler (10) and converts the wind energy into electric energy for use by a movable heating trolley (13). The leveler (10) comprises a variable-frequency power supply (11), a water chilling machine (12) and the movable heating trolley (13). The variable-frequency power supply (11) is mounted above the water chilling machine (12), supplies power needed by the water chilling machine (12) via a first electric wire assembly (31), and transmits power into the movable heating trolley (13) via a second electric wire assembly (33). A coaxial transformer and an electromagnetic induction heating coil are mounted in the movable heating trolley (13), wherein the coaxial transformer is used for reducing a current input by the variable-frequency power supply (11) within a safe voltage range, and the water chilling machine (12) is used for transferring heat in the variable-frequency power supply (11) and the movable heating trolley (13). The energy recovery device comprises a power generation part on the front side of the water chilling machine (12) and a current conversion part on the movable heating trolley (13). Further provided is a leveling method having the energy recovery function. The device can collect and store wind energy generated when the leveler performs leveling, and convert the wind energy into electric energy for use by the movable heating trolley, thereby improving the energy utilization rate.
