[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 and Figure 2 The construction positioning and calibration device of the flywheel energy storage device of this embodiment includes a positioning ring 101, the positioning ring 101 is connected to a supporting device for supporting the positioning ring 101, the inner ring of the positioning ring 101 is symmetrically provided with a plurality of arc-shaped fixed plates 203, generally at least two arc-shaped fixed plates 203 are provided, and a flywheel energy storage device positioning and calibration cavity is formed between the plurality of arc-shaped fixed plates 203, and the arc-shaped fixed plates 203 are provided with an adjustment component 5 that can slide circumferentially along the arc-shaped fixed plates 203, and the end of the adjustment component 5 facing the axis of the positioning ring 101 can be inserted into the outer casing groove of the flywheel energy storage device, and the positioning ring 101 is connected to an arc-shaped fixed plate driving device for driving all arc-shaped fixed plates 203 to synchronously approach or move away from the axis of the positioning ring 101. The construction positioning and calibration method of the flywheel energy storage device based on the construction positioning and calibration device of the flywheel energy storage device of this embodiment includes the following processes: The supporting device is fixed in a suitable position so that the central axis of the positioning ring 101 is in a vertical state. Then, according to the position of the outer shell groove of the flywheel energy storage device, the adjustment component 5 is slid along the arc-shaped fixed plate 203 to move the adjustment component 5 to a position corresponding to the outer shell groove of the flywheel energy storage device. At this time, the flywheel energy storage device is placed in the positioning ring 101 (i.e., a plurality of arc-shaped fixed plates 203 constitute a positioning and calibration cavity for the flywheel energy storage device). Then, all the arc-shaped fixed plates 203 are driven synchronously to approach the flywheel energy storage device by the arc-shaped fixed plate driving device, so that the adjustment component 5 is inserted into the outer shell groove of the flywheel energy storage device until the inner surface of the arc-shaped fixed plate 203 contacts the outer shell of the flywheel energy storage device. At this time, the positioning and calibration of the flywheel energy storage device are realized.

[0020] As a preferred embodiment of the present invention, see Figure 1-Figure 4On the basis of the above embodiments, the arc-shaped fixed plate driving device of this embodiment can adopt the following structure: the arc-shaped fixed plate driving device includes a threaded rod 202, one end of the threaded rod 202 penetrates the positioning ring 101 along the radial direction of the positioning ring 101 and is fixedly connected to the arc-shaped fixed plate 203, a driven wheel 302 is threadedly connected to the threaded rod 202, the driven wheel 302 is rotatably connected to the outer side of the positioning ring 101, and the driven wheel 302 is connected to a driven wheel driving device for driving the driven wheel 302 to rotate. In this embodiment, after the adjustment component 5 is inserted into the outer casing groove of the flywheel energy storage device, the arc-shaped fixed plate 203 is limited by the adjustment component 5 and the outer casing groove of the flywheel energy storage device. When the driven wheel 302 is driven to rotate, the arc-shaped fixed plate 203 is limited, so the arc-shaped fixed plate 203 cannot rotate. At this time, the threaded rod 202 can only move axially along the threaded rod 202, thereby realizing the arc-shaped fixed plate 203 approaching or moving away from the axis of the positioning ring 101, and further realizing the arc-shaped fixed plate 203 approaching or moving away from the outer casing surface of the flywheel energy storage device. Before the flywheel energy storage device is placed in the positioning ring 101, the driven wheel 302 is first driven to rotate by the driven wheel driving device, so that the arc-shaped fixed plate 203 is moved away from the axis of the positioning ring 101. The size of the flywheel energy storage device positioning and calibration cavity formed between the plurality of arc-shaped fixed plates 203 must be able to allow the outer shell of the flywheel energy storage device to be placed therein. After the flywheel energy storage device is placed in the positioning ring 101, the driven wheel 302 is driven to rotate by the driven wheel driving device, so that the arc-shaped fixed plate 203 is moved closer to the axis of the positioning ring 101. Finally, the adjustment component 5 is inserted into the outer shell groove of the flywheel energy storage device until the inner surface of the arc-shaped fixed plate 203 contacts the outer shell of the flywheel energy storage device. At this time, the positioning and calibration of the flywheel energy storage device are realized.

[0021] As a preferred embodiment of the present invention, see Figure 2-Figure 4, based on the above embodiments, in this embodiment, the way the driven wheel 302 is rotatably connected to the outer side of the positioning ring 101 is as follows: Specifically, a connecting block 402 is coaxially provided on the side of the driven wheel 302 close to the positioning ring 101. The connecting block 402 is a hollow frustum structure, and the inner wall surface of the connecting block 402 is a smooth surface. A connecting groove 401 for embedding the connecting block 402 is formed on the outer side of the positioning ring 101. The shapes of the connecting block 402 and the connecting groove 401 are adapted to each other, so that the driven wheel 302 and the positioning ring 101 are rotatably connected through the connecting block 402 and the connecting groove 401. Since the connecting block 402 is a hollow frustum structure, its small-end side is coaxially connected to the driven wheel 302 and its large-end side is away from the driven wheel 302. Therefore, after the connecting block 402 is arranged in the connecting groove 401, the connecting groove 401 can realize the circumferential and axial limiting of the connecting block 402, so that the connecting block 402 can only rotate around the central axis of the connecting block 402 in the connecting groove 401. Moreover, since the connecting block 402 and the connecting groove 401 are in surface contact, the circumferential and axial limiting effects of the connecting groove 401 on the connecting block 402 are good, and the stress at the contact part is relatively small, ensuring the reliability of the connection between the connecting block 402 and the connecting groove 401. It is preferably a clearance fit between the connecting block 402 and the connecting groove 401, which can ensure the flexible rotation of the driven wheel 302.

[0022] As a preferred embodiment of the present invention, referring to Figure 1-Figure 3 , in this embodiment, two arc-shaped fixing plates 203 are symmetrically arranged on the inner ring of the positioning ring 101. At this time, the threaded rods 202 connected to the two arc-shaped fixing plates 203 are coaxial, and the rotation directions of the threaded rods 202 connected to each arc-shaped fixing plate 203 are opposite. The driven wheel driving device includes an ear plate 205 fixedly connected to the outer wall of the positioning ring 101. A transmission rod 206 is rotatably connected to the ear plate 205. The transmission rod 206 penetrates through the ear plate 205 and is coaxial with the threaded rod 202. Active wheels 302 are coaxially and fixedly provided at both ends of the transmission rod 206 respectively. The active wheels 302 and the driven wheels 302 on the same side are connected by a belt 303. The transmission rod 206 is connected with a transmission rod driving device for driving the transmission rod 206 to rotate. In this embodiment, when the transmission rod 206 is driven to rotate by the transmission rod driving device, the transmission rod 206 synchronously drives the two active wheels 302 to rotate. Then, the two active wheels 302 respectively drive the corresponding connected driven wheels 302 to rotate. Since the rotation directions of the threaded rods 202 connected to the two arc-shaped fixing plates 203 are opposite, when the two driven wheels 302 rotate synchronously, the moving directions of the two threaded rods 202 are opposite, so that the two threaded rods 202 will move towards or away from each other synchronously, and thus the two arc-shaped fixing plates 203 approach or move away from the flywheel energy storage device housing synchronously. In this embodiment, it is required that the diameters of the two active wheels 302 are the same and the diameters of the two driven wheels 302 are the same, so that the transmission ratios between the two groups of active wheels and driven wheels are the same.

[0023] As a preferred embodiment of the present invention, see Figure 1-Figure 2 In this embodiment, the transmission rod adopts a hand wheel or a motor. When the transmission rod adopts a hand wheel, the hand wheel is fixedly mounted on one end of the transmission rod 206. When the transmission rod adopts a motor, the motor adopts a reversible motor, and the output shaft of the reversible motor is connected to one end of the transmission rod 206. The transmission rod 206 can be driven to rotate by either a hand wheel or a motor, and those skilled in the art can select one according to actual needs, and the present invention does not make a specific limitation.

One end of the guide rod 204 is fixedly connected to the arc-shaped fixed plate 203, and the other end of the guide rod 204 passes through the positioning ring 101. There is a clearance fit between the hole provided on the positioning ring 101 for the guide rod 204 to pass through and the guide rod 204. In this embodiment, the guide rod 204 can limit the arc-shaped fixed plate 203 to prevent the arc-shaped fixed plate 203 from rotating around the axis of the threaded rod 202. Specifically, the arc-shaped fixed plate 203 has two limit points in the circumferential direction (one of the limit points is the connection point between the arc-shaped fixed plate 203 and the threaded rod 202, and the other limit point is the connection point between the arc-shaped fixed plate 203 and the guide rod 204), and then when the driven wheel 302 rotates, the arc-shaped fixed plate 203 only moves along the radial direction of the positioning ring 101.

[0025] As a preferred embodiment of the present invention, see Figure 1 , Figure 2 and Figure 4 In this embodiment, the adjustment component 5 includes an adjustment block 502 and a fixed block 503. The adjustment block 502 is a T-shaped block. A T-shaped adjustment groove 501 that matches the shape of the adjustment block 502 is opened on the arc-shaped fixed plate 203. One end of the adjustment block 502 is embedded in the adjustment groove 501, and the other end of the adjustment block 502 extends out of the adjustment groove 501 and is fixedly connected to the fixed block 503. The adjustment block 502 can slide along the adjustment groove 501, and the fixed block 503 can be inserted into the housing groove of the flywheel energy storage device.

[0026] As a preferred embodiment of the present invention, in this embodiment, at least two adjustment components 5 are provided on the arc-shaped fixed plate 203, and generally two or three adjustment components 5 are installed.

[0027] As a preferred embodiment of the present invention, see Figure 1 , Figure 2In this embodiment, at least three supporting devices for supporting the positioning ring 101 are evenly connected to the circumference of the positioning ring 101. Generally, three supporting devices are sufficient, wherein the supporting device adopts a supporting plate 102 or a telescopic rod. The length of the supporting plate 102 is fixed. When in use, the supporting plate 102 is fixed in a suitable position through a fixed cone so that the central axis of the positioning ring 101 is in a vertical state; the length of the telescopic rod is variable. When in use, the length of the telescopic rod is adjusted to make the central axis of the positioning ring 101 in a vertical state.
