Technical Field

[0028] In this embodiment, reference Figure 5 The heat dissipation mechanism 4 includes a heat dissipation box 401 fixedly connected to the outer wall of the flywheel energy storage unit 1. A lower guide pipe 402 is fixedly connected to the lower center of the outer wall of the heat dissipation box 401 and to the side near the flywheel energy storage unit 1. A heat exchange sleeve 403 is fixedly connected to the outer wall of the lower guide pipe 402 and to the motor position near the flywheel energy storage unit 1. A baffle plate 404 is fixedly connected to the inner wall of the heat exchange sleeve 403. A baffle plate 404 is fixedly connected to the outer wall of the heat exchange sleeve 403 and to the inside of the flywheel energy storage unit 1. A support rod 405 is attached. A connecting pad 406 is fixedly connected to the outer wall of the heat exchange sleeve 403 near the motor side inside the flywheel energy storage device 1. An upper guide pipe 407 is fixedly connected to the outer wall of the heat exchange sleeve 403 above the lower guide pipe 402. An inlet pipe 408 is fixedly connected to the inside of the heat dissipation box 401 at the corresponding position of the lower guide pipe 402. An outlet pipe 409 is fixedly connected to the inside of the heat dissipation box 401 at the corresponding position of the upper guide pipe 407.

[0029] The heat sink 401 and the baffle 404 are made of thermal insulation material. The heat sink 401 has an I-shaped structure design. Multiple sets of the lower guide pipe 402, the upper guide pipe 407 and the baffle 404 are provided. The multiple sets of baffles 404 are arranged alternately in the heat exchange sleeve 403. The connection between the connecting pad 406 and the motor inside the flywheel energy storage 1 and the connection between the support rod 405 and the shell of the flywheel energy storage 1 are fixed connections. The heat exchange sleeve 403 is made of copper. The lower guide pipe 402 and the upper guide pipe 407 both pass through the flywheel energy storage 1 and extend into the heat sink 401. The heat exchange sleeve 403 and the baffle 404 are both annular structures. The connecting pad 406 is made of thermally conductive silicone grease.

[0030] The working process of this utility model is as follows: When the flywheel energy storage assembly designed using this scheme is running, the controller 6 turns off the electromagnet 313, and the electromagnet 313 no longer attracts the sliding seat 302. The sliding seat 302 drives the moving wheel 304 to move downwards. When the moving wheel 304 falls to the ground, the controller 6 starts the micro-pump 310. The micro-pump 310 sends the hydraulic oil in the storage sleeve 311 into the fixed sleeve 301 through the delivery pipe 309. The hydraulic oil pushes the fixed frame 2 and the flywheel energy storage device 1 upwards through the fixed sleeve 301. The fixed frame 2 is lifted off the ground. The fixed frame 2, relying on the moving wheel 304, drives the flywheel energy storage device 1 to move. When the fixed frame 2 moves to the appropriate position, the pushing of the fixed frame 2 stops. The controller 6 activates the micro electric push rod 307, which pushes the clamping plate 305 to move inward. The inward-moving clamping plate 305 clamps the rotating shaft 303, preventing the rotating shaft 303 and the moving wheel 304 from rotating and thus preventing the fixed frame 2 from moving. The micro delivery pump 310 delivers the hydraulic oil in the fixed sleeve 301 into the storage sleeve 311 through the delivery pipe 309. The hydraulic oil in the fixed sleeve 301 gradually decreases, and the hydraulic oil can no longer support the fixed sleeve 301 and the fixed frame 2. The fixed frame 2 drives the flywheel energy storage device 1 to slowly fall to the ground. The controller 6 activates the electromagnet 313, which attracts the sliding seat 302 to move upward. The rising sliding seat 302 drives the moving wheel 304 to leave the ground.

[0031] When the flywheel energy storage device 1 is running, the heat generated by the motor in the flywheel energy storage device 1 is transferred to the heat exchange sleeve 403 through the connecting pad 406. Low-temperature coolant is injected into the inlet pipe 408. The low-temperature coolant flows into the heat sink 401 through the inlet pipe 408 and into the heat exchange sleeve 403 along the lower guide pipe 402 in the heat sink 401. The low-temperature coolant entering the heat exchange sleeve 403 flows upward along the baffle plate 404. The upward-flowing low-temperature coolant carries away the heat in the heat exchange sleeve 403. The coolant that has absorbed the heat flows into the heat sink 401 through the upper guide pipe 407 and flows out through the outlet pipe 409. The continuously flowing coolant can carry away the heat generated by the motor in the flywheel energy storage device 1 in a timely manner.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
