Abstract

The invention relates to a superconducting flywheel main shaft positioning device and a using method thereof. The positioning device comprises a vacuum sealing cavity, a radial positioning mechanism and a motor, wherein the vacuum sealing cavity is arranged above a superconducting flywheel host, the radial positioning mechanism is arranged in the vacuum sealing cavity, and the motor is positionedon one side of the vacuum sealing cavity. The radial positioning mechanism comprises a sliding rail, a left sliding block and a right sliding block which are located below the sliding rail and are insliding fit with the sliding rail, a screw rod which penetrates through the left sliding block and the right sliding block in sequence and is in threaded fit with the left sliding block and the rightsliding block, a left guide rod and a right guide rod which are arranged at the bottoms of the left sliding block and the right sliding block respectively, a left clamping block which is arranged on the left guide rod in a sleeved mode and is in clearance fit with the left guide rod, and a right clamping block which is arranged on the right guide rod in a sleeved mode and is in clearance fit withthe right guide rod. The output shaft of the motor is connected with one end of the screw rod. The left clamping block and the right clamping block are provided with clamping grooves respectively. According to the positioning device, the main shaft of the superconducting flywheel can be subjected to reliable, accurate and rapid radial positioning, and the radial displacement caused by axial movement when the flywheel main shaft is in a non-working state is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of high-temperature superconducting flywheel energy storage systems, in particular to a superconducting flywheel spindle positioning device and a method for using the same. Background technique [0002] With the development of the new energy field, energy storage technology has become a worldwide research topic. Among many energy storage technologies, flywheel energy storage has been highly valued at home and abroad for its advantages of high power, high efficiency, long life, high energy storage density, clean and pollution-free. Superconducting flywheel energy storage technology has broad prospects, but the stability and reliability of superconducting flywheel operation still need to be improved. When the superconducting flywheel energy storage device operates under the condition of field cooling, because the pinning effect of the superconducting block needs to capture the magnetic flux, the rotor spindle...
