Technical Field

[0001] This invention belongs to the field of flywheel energy storage technology, specifically a flywheel energy storage device and method for construction positioning and calibration. Background Technology

[0002] Flywheel energy storage devices are a type of energy storage that uses an electric motor to drive a flywheel to rotate at high speed, converting mechanical energy into electrical energy. The core component is the flywheel itself, which is usually made of carbon fiber material to increase the rotor's limiting angular velocity and reduce weight, thereby increasing the energy storage capacity of the energy storage system.

[0003] During the construction of flywheel energy storage devices, positioning and calibration devices are required for positioning and calibration. Generally, the energy storage power of flywheel energy storage devices varies, and the diameter of the flywheel also varies. However, existing positioning and calibration devices have fixed structures and single functions, and can only be used to position and calibrate flywheel energy storage devices of the same size. It is difficult to adjust the positioning and calibration devices according to different sizes of flywheel energy storage devices, so that the positioning and calibration devices can be applied to flywheel energy storage devices of different sizes. This reduces the adaptability of the positioning and calibration devices and also affects their performance. Summary of the Invention

The driven wheel is connected to a driven wheel drive device for driving the driven wheel to rotate.

[0007] Preferably, a connecting block is coaxially provided on the side of the driven wheel near the positioning ring. The connecting block is a hollow frustum structure. A connecting groove for embedding the connecting block is provided on the outer side of the positioning ring. The shape of the connecting block and the connecting groove are adapted to each other so that the driven wheel and the positioning ring are rotatably connected through the connecting block and the connecting groove.

[0008] Preferably, the inner ring of the positioning ring is symmetrically provided with two arc-shaped fixed plates, and the threaded rods connected to each arc-shaped fixed plate have opposite rotation directions. The driven wheel drive device includes an ear plate fixedly connected to the outer wall of the positioning ring. The ear plate is rotatably connected to a transmission rod. The transmission rod passes through the ear plate and is coaxial with the threaded rod. Both ends of the transmission rod are respectively fixedly provided with driving wheels on the same side. The driving wheel and the driven wheel on the same side are connected by a belt. The transmission rod is connected to a transmission rod drive device for driving the transmission rod to rotate.

[0009] Preferably, the transmission rod is a handwheel or a motor. When the transmission rod is a handwheel, the handwheel is fixedly installed at one end of the transmission rod. When the transmission rod is a motor, the motor is a reversible motor, and the output shaft of the reversible motor is connected to one end of the transmission rod.

[0010] Preferably, a guide rod is fixedly connected to the arc-shaped plate. The axis of the guide rod is parallel to the axis of the threaded rod connected to the arc-shaped plate. One end of the guide rod is fixedly connected to the arc-shaped plate, and the other end of the guide rod passes through a positioning ring. The hole on the positioning ring for the guide rod to pass through is clearance-fitted with the guide rod.

[0011] Preferably, the adjustment component includes an adjustment block and a fixing block. The adjustment block is a T-shaped block, and the arc-shaped fixing plate has a T-shaped adjustment groove adapted to the shape of the adjustment block. One end of the adjustment block is embedded in the adjustment groove, and the other end of the adjustment block extends out of the adjustment groove and is fixedly connected to the fixing block. The fixing block can be inserted into the slot of the flywheel energy storage device housing.

[0012] Preferably, the arc-shaped plate is provided with at least two adjustment components.

[0013] Preferably, the positioning ring is circumferentially connected with at least three support devices for supporting the positioning ring, wherein the support devices are support plates or telescopic rods.

[0014] The present invention also provides a method for construction positioning and calibration of a flywheel energy storage device based on the above-mentioned flywheel energy storage device construction positioning and calibration device, comprising the following steps: Fix the support device in a suitable position so that the central axis of the positioning ring is vertical. Then, according to the position of the flywheel energy storage device's outer shell groove, slide the adjustment component along the arc-shaped fixed plate to move the adjustment component to the position corresponding to the flywheel energy storage device's outer shell groove.

It is stably supported by a support device. The inner ring of the positioning ring is symmetrically equipped with several arc-shaped fixed plates, which together form the positioning and calibration cavity for the flywheel energy storage device. Therefore, the flywheel energy storage device can be positioned using these arc-shaped fixed plates. An arc-shaped fixed plate driving device is connected to the positioning ring to drive all the arc-shaped fixed plates synchronously towards or away from the positioning ring axis. Therefore, the movement of all the arc-shaped fixed plates is synchronous. The arc-shaped fixed plates can be driven by the arc-shaped fixed plate driving device to... To achieve stable positioning of the flywheel energy storage device, an adjustment component is provided on an arc-shaped fixed plate that can slide circumferentially along the plate.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figure 1 and Figure 2 This embodiment of the flywheel energy storage device construction positioning and calibration device includes a positioning ring 101. The positioning ring 101 is connected to a support device for supporting the positioning ring 101. A plurality of arc-shaped fixing plates 203 are symmetrically arranged on the inner ring of the positioning ring 101. Generally, at least two arc-shaped fixing plates 203 are provided. The plurality of arc-shaped fixing plates 203 form a positioning and calibration cavity for the flywheel energy storage device. An adjustment component 5 is provided on each arc-shaped fixing plate 203, which can slide circumferentially along the arc-shaped fixing plate 203. One end of the adjustment component 5 facing the axis of the positioning ring 101 can be inserted into a groove in the outer shell of the flywheel energy storage device. An arc-shaped fixing plate driving device is connected to the positioning ring 101 for driving all arc-shaped fixing plates 203 to synchronously approach or move away from the axis of the positioning ring 101. Based on this embodiment of the flywheel energy storage device construction positioning and calibration device, the flywheel energy storage device construction positioning and calibration method includes the following process: The support device is fixed in a suitable position so that the central axis of the positioning ring 101 is vertical. Then, according to the position of the flywheel energy storage device housing groove, the adjusting component 5 is slid along the arc-shaped fixed plate 203 to move the adjusting component 5 to the position corresponding to the flywheel energy storage device housing groove. At this time, the flywheel energy storage device is placed inside the positioning ring 101 (that is, the positioning and calibration cavity of the flywheel energy storage device is formed by several arc-shaped fixed plates 203). Then, the arc-shaped fixed plate driving device drives all the arc-shaped fixed plates 203 to move closer to the flywheel energy storage device at the same time, so that the adjusting component 5 is inserted into the flywheel energy storage device housing groove until the inner surface of the arc-shaped fixed plate 203 contacts the flywheel energy storage device housing. At this time, the positioning and calibration of the flywheel energy storage device is realized.

[0020] As a preferred embodiment of the present invention, see Figures 1-4Based on 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 passes through the positioning ring 101 radially 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 slot of the flywheel energy storage device housing, the arc-shaped fixed plate 203 is limited by the adjustment component 5 and the slot of the flywheel energy storage device housing. When the driven wheel 302 is driven to rotate, the arc-shaped fixed plate 203 cannot rotate because it is limited. At this time, only the threaded rod 202 can move along the axial direction of the threaded rod 202, thereby realizing that the arc-shaped fixed plate 203 is close to or away from the axis of the positioning ring 101, and thus realizing that the arc-shaped fixed plate 203 is close to or away from the surface of the flywheel energy storage device housing. Before the flywheel energy storage device is placed into the positioning ring 101, the driven wheel 302 is driven to rotate by the driven wheel drive device, thereby moving the arc-shaped fixed plate 203 away from the axis of the positioning ring 101. The size of the positioning and calibration cavity of the flywheel energy storage device formed by the arc-shaped fixed plates 203 is large enough to allow the flywheel energy storage device housing to be inserted. 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 drive device, causing the arc-shaped fixed plate 203 to move closer to the axis of the positioning ring 101. Finally, the adjusting component 5 is inserted into the slot of the flywheel energy storage device housing until the inner surface of the arc-shaped fixed plate 203 contacts the flywheel energy storage device housing. At this time, the positioning and calibration of the flywheel energy storage device is achieved.

[0021] As a preferred embodiment of the present invention, see Figures 2-4Based on the above embodiments, in this embodiment, the driven wheel 302 is rotatably connected to the outer side of the positioning ring 101 as follows: Specifically, a connecting block 402 is coaxially provided on the side of the driven wheel 302 near 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 provided 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. Because the connecting block 402 is a hollow frustum structure, with its small end coaxially connected to the driven wheel 302 and its large end away from the driven wheel 302, the connecting block 402 is positioned behind the connecting groove 401. The connecting groove 401 can effectively limit the circumferential and axial movement of the connecting block 402, allowing it to rotate only around its central axis within the connecting groove 401. Furthermore, the connection between the connecting block 402 and the connecting groove 401 is a surface contact, resulting in good circumferential and axial limiting of the connecting block 402 and relatively low stress at the contact points, ensuring a reliable connection between the connecting block 402 and the connecting groove 401. Ideally, the connection between the connecting block 402 and the connecting groove 401 should be a clearance fit to ensure the driven wheel 302 rotates freely.

[0022] As a preferred embodiment of the present invention, see Figures 1-3 In this embodiment, the inner ring of the positioning ring 101 is symmetrically provided with two arc-shaped fixed plates 203. At this time, the threaded rods 202 connected to the two arc-shaped fixed plates 203 are coaxial, and the threaded rods 202 connected to each arc-shaped fixed plate 203 rotate in opposite directions. The driven wheel drive device includes an ear plate 205 fixedly connected to the outer wall of the positioning ring 101. The ear plate 205 is rotatably connected to a transmission rod 206. The transmission rod 206 passes through the ear plate 205 and is coaxial with the threaded rod 202. The two ends of the transmission rod 206 are respectively coaxially fixedly provided with driving wheels 301. The driving wheel 301 on the same side is connected to the driven wheel 302 through a belt 303. The transmission rod 206 is connected to a transmission rod drive 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 drive device, the transmission rod 206 synchronously drives the two driving wheels 301 to rotate. The two driving wheels 301 then drive the corresponding driven wheels 302 to rotate. Since the threaded rods 202 connected to the two arc-shaped fixed plates 203 rotate in opposite directions, when the two driven wheels 302 rotate synchronously, the movement directions of the two threaded rods 202 are opposite. This causes the two threaded rods 202 to move synchronously towards or away from each other, thereby enabling the two arc-shaped fixed plates 203 to synchronously approach or move away from the flywheel energy storage device housing. In this embodiment, it is required that the diameters of the two driving wheels 301 and the two driven wheels 302 are the same, thus ensuring that the transmission ratio between the two sets of driving wheels and driven wheels is the same.

[0023] As a preferred embodiment of the present invention, see Figures 1-2 In this embodiment, the transmission rod is either a handwheel or a motor. When the transmission rod is a handwheel, the handwheel is fixedly installed at one end of the transmission rod 206. When the transmission rod is a motor, the motor is 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 handwheel or a motor. Those skilled in the art can choose according to actual needs, and this invention does not impose specific limitations.

[0024] As a preferred embodiment of the present invention, see Figures 1-3 In this embodiment, a guide rod 204 is fixedly connected to the arc-shaped fixed plate 203. The axis of the guide rod 204 is parallel to the axis of the threaded rod 202 connected to the arc-shaped fixed plate 203. 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. The hole on the positioning ring 101 through which the guide rod 204 passes is clearance-fitted with the guide rod 204. In this embodiment, the guide rod 204 can limit the arc-shaped fixed plate 203 and 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 limiting points in the circumferential direction (one limiting point is the connection point between the arc-shaped fixed plate 203 and the threaded rod 202, and the other limiting point is the connection point between the arc-shaped fixed plate 203 and the guide rod 204). Therefore, when the driven wheel 302 rotates, the arc-shaped fixed plate 203 only moves radially along 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 fixing block 503. The adjustment block 502 is a T-shaped block. The arc-shaped fixed plate 203 has a T-shaped adjustment groove 501 that matches the shape of the adjustment block 502. 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 fixing block 503. The adjustment block 502 can slide along the adjustment groove 501, and the fixing block 503 can be inserted into the slot of the flywheel energy storage device housing.

[0026] In a preferred embodiment of the present invention, at least two adjustment components 5 are provided on the arc-shaped fixed plate 203. Generally, two or three adjustment components 5 are sufficient.

[0027] As a preferred embodiment of the present invention, see Figure 1 , Figure 2In this embodiment, at least three support devices for supporting the positioning ring 101 are evenly connected circumferentially. Generally, three support devices are sufficient. The support devices are either support plates 102 or telescopic rods. The length of the support plate 102 is fixed. In use, the support plate 102 is fixed in a suitable position by a fixed cone so that the central axis of the positioning ring 101 is vertical. The length of the telescopic rod is variable. In use, the length of the telescopic rod is adjusted so that the central axis of the positioning ring 101 is vertical.

[0028] Example Please see Figures 1 to 4 The flywheel energy storage device construction positioning and calibration device provided in this embodiment includes a positioning and calibration device body 1, a positioning component 2, a transmission component 3, a connecting component 4, and an adjusting component 5 for the construction of the flywheel energy storage device. The positioning and calibration device body 1 includes a positioning ring 101 and a support plate 102. Three support plates 102 are fixedly arranged in a ring array on the positioning ring 101. The positioning component 2 is arranged on the positioning ring 101. The positioning component 2 includes a through-hole groove 201, a threaded rod 202, an arc-shaped fixed plate 203, a guide rod 204, an ear plate 205, and a transmission rod 206. Two through-hole grooves 201 are symmetrically opened on the positioning ring 101. The threaded rod 202 slides through the through-hole groove 201, and the two threaded rods 202... The threads are opposite in direction, so that when the transmission rod 206 rotates, the two arc-shaped fixed plates 203 can move relative to each other or away from each other through the transmission assembly 3; the arc-shaped fixed plates 203 are fixedly connected to the ends of the threaded rod 202 and can contact the outer shell of the flywheel energy storage device, and the two arc-shaped fixed plates 203 form a positioning and calibration cavity for the flywheel energy storage device; two guide rods 204 are symmetrically slidably passed through the positioning ring 101 and fixedly connected to the arc-shaped fixed plates 203; ear plates 205 are fixed on the outer surface of the positioning ring 101; the transmission rod 206 passes through the ear plate 205 and is rotatably connected to the ear plate 205 through a bearing, and the transmission rod 206 is connected to the threaded rod 202 through the transmission assembly 3; the axes of the transmission rod 206 and the threaded rod 202 are parallel; The transmission assembly 3 includes a drive wheel 301, a driven wheel 302, and a belt 303; the two drive wheels 301 are symmetrically sleeved on both ends of the transmission rod 206; the driven wheel 302 is screwed onto the threaded rod 202 and rotatably connected to the positioning ring 101 through the connecting assembly 4, and the driven wheel 302 is connected to the drive wheel 301 through the belt 303. The connecting component 4 includes a connecting groove 401 and a connecting block 402; two connecting grooves 401 are symmetrically opened on the outer surface of the positioning ring 101; the connecting block 402 is rotatably inserted into the connecting groove 401 and fixedly connected to the driven wheel 302; the connecting block 402 is sleeved on the threaded rod 202 and does not contact the threaded rod 202; the connecting block 402 is a hollow frustum structure, and the size of the side of the connecting block 402 near the driven wheel 302 is smaller than the size of the side of the connecting block 402 away from the driven wheel 302, thereby fixing the position of the driven wheel 302.

[0029] The adjustment assembly 5 is arranged on the arc-shaped fixed plate 203. The adjustment assembly 5 includes an adjustment groove 501, an adjustment block 502, and a fixed block 503. The inner surface of the arc-shaped fixed plate 203 has an adjustment groove 501. The three adjustment blocks 502 are arranged in a ring array and slide through the adjustment groove 501. The fixed block 503 is fixedly connected to the end of the adjustment block 502 and contacts the flywheel energy storage device housing groove. In order to ensure that the flywheel energy storage device can effectively store and release energy, balance the speed fluctuation of the engine through the rotational inertia of the flywheel energy storage device, enhance the structural strength of the flywheel, and provide a better heat dissipation channel, a groove is provided on the flywheel energy storage device housing. Therefore, the adjustment assembly 5 can adapt to flywheel energy storage device housing grooves with different spacing. The adjustment block 502 has a T-shaped structure, and the size of the side of the adjustment block 502 closer to the fixed block 503 is smaller than the size of the side of the adjustment block 502 away from the fixed block 503, so that the rotation range of the adjustment block 502 is fixed.

[0030] In this embodiment, by setting up a positioning component 2, a transmission component 3, and a connecting component 4, the support plate 102 is fixed in a suitable position by a fixing cone. Then, the flywheel energy storage device is placed inside the positioning ring 101. Next, the handwheel on the transmission rod 206 is rotated, causing the transmission rod 206 to rotate through the bearing and the ear plate 205, causing the two driving wheels 301 to rotate. The driving wheels 301 drive the driven wheel 302 to rotate through the belt 303, causing the connecting block 402 to rotate in the connecting groove 401, and causing the driven wheel 302 to be threadedly connected to the threaded rod 202, thus connecting the threaded rod... The movement of 202 within the through-hole groove 201 causes the guide rod 204 to move within the positioning ring 101, resulting in relative movement of the two arc-shaped fixed plates 203 until the inner surface of the arc-shaped fixed plates 203 contacts the flywheel energy storage device housing. At this point, the flywheel energy storage device can be positioned and calibrated. Compared to existing technologies, this invention has a simple and reasonable structure and ingenious design. The positioning and calibration device body 1 can be adjusted according to different sizes of flywheel energy storage devices, making it adaptable to flywheel energy storage devices of different sizes. In this embodiment, by setting the adjustment component 5, the fixed block 503 is moved according to the position of the slot on the flywheel energy storage device housing, causing the adjustment block 502 to slide within the adjustment groove 501 until the fixed block 503 moves to a suitable position. This allows the fixed block 503 to adapt to flywheel energy storage device housing slots with different spacing. Furthermore, by inserting the fixed block 503 into the flywheel energy storage device housing slot, the stability of the flywheel energy storage device's positioning and calibration can be improved.

[0031] The working principle of the flywheel energy storage device construction positioning and calibration device in this embodiment is as follows: In use, first, fix the support plate 102 in a suitable position using the fixing cone. Then, according to the position of the groove on the flywheel energy storage device housing, move the fixing block 503 so that the adjusting block 502 slides in the adjusting groove 501 until the fixing block 503 moves to a suitable position. At this time, place the flywheel energy storage device in the positioning ring 101. Next, rotate the handwheel on the transmission rod 206 so that the transmission rod 206 rotates through the bearing and the ear plate 205, causing the two drive wheels 301 to rotate, and causing the drive wheels 301 to rotate through the belt 303. The driven wheel 302 rotates, causing the connecting block 402 to rotate within the connecting groove 401. This causes the driven wheel 302 to be threadedly connected to the threaded rod 202, which in turn moves within the through-hole groove 201. This causes the guide rod 204 to move within the positioning ring 101, resulting in relative movement of the two arc-shaped fixed plates 203. Consequently, the fixing block 503 is inserted into the flywheel energy storage device housing groove until the inner surface of the arc-shaped fixed plate 203 contacts the flywheel energy storage device housing. At this point, the flywheel energy storage device can be positioned and calibrated.

[0032] As can be seen from the above scheme, the present invention, by setting up a positioning component, a transmission component, and a connecting component, fixes the support plate in a suitable position using a fixing cone. Then, the flywheel energy storage device is placed inside the positioning ring. Next, the handwheel on the transmission rod is rotated, causing the transmission rod to rotate through the bearing and the ear plate, causing the two driving wheels to rotate. The driving wheels drive the driven wheel to rotate through the belt, causing the connecting block to rotate in the connecting groove, causing the driven wheel to be threadedly connected to the threaded rod, causing the threaded rod to move in the through hole groove, causing the guide rod to move in the positioning ring, and causing the two arc-shaped fixed plates to move relative to each other until the inner surface of the arc-shaped fixed plates contacts the outer shell of the flywheel energy storage device. At this point, the flywheel energy storage device can be positioned and calibrated. Compared with the prior art, the present invention has a simple and reasonable structure and ingenious design. The positioning and calibration device body can be adjusted according to different sizes of flywheel energy storage devices, making the positioning and calibration device body applicable to flywheel energy storage devices of different sizes, with strong adaptability.

[0033] This invention, by setting an adjustment component, moves a fixed block according to the position of the slot on the flywheel energy storage device housing, allowing the adjustment block to slide within the adjustment slot until the fixed block moves to a suitable position. This allows the fixed block to adapt to flywheel energy storage device housing slots with different spacings. Furthermore, by inserting the fixed block into the flywheel energy storage device housing slot, the stability of the flywheel energy storage device's positioning and calibration can be improved.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
