Description

Technical Field

[0001] This utility model relates to the field of flywheel energy storage technology, and in particular to a flywheel energy storage experimental device. Background Technology

[0002] Against the backdrop of an era in which the energy structure is rapidly transforming towards cleaner and smarter energy, flywheel energy storage technology has become a key research direction in fields such as power system frequency regulation, backup power, and industrial energy conservation, thanks to its advantages such as high power density, long cycle life, and environmental friendliness. Flywheel energy storage systems store kinetic energy by accelerating a flywheel driven by an electric motor, and when needed, they use the flywheel to decelerate and drive a generator to generate electricity, thus achieving bidirectional conversion between electrical and kinetic energy.

[0003] However, when traditional devices stop operating, the flywheel may continue to rotate due to its large inertia. However, due to insufficient braking force of the drive components or failure to brake in time, the flywheel may reverse. At this time, the torque generated by the rotor due to inertia will cause severe alternating loads on the bearings and support structures, leading to problems such as increased vibration and excessive bearing displacement, which greatly shortens the service life of the device.

[0004] Therefore, it is necessary to provide a flywheel energy storage experimental device to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a flywheel energy storage experimental device, which solves the problem that the lack of a reverse rotation limiting function in traditional devices leads to a significantly shortened service life.

[0009] Preferably, the main body of the device is provided with a drive assembly, the drive assembly including a drive fixing frame mounted on the device base plate, and a drive component is fixedly mounted on the drive fixing frame.

[0010] Preferably, the protection component includes a flywheel installed at the output end of the drive component, the flywheel is surrounded by a protective shell, and the protective shell has heat dissipation holes.

[0011] Preferably, the main body of the device includes a support assembly, the support assembly includes a device support rod installed at the bottom of the device base plate, and the bottom of the device support rod is equipped with an anti-slip component for preventing the main body of the device from slipping.

[0012] Preferably, a controller is installed on the shock-absorbing plate.

[0013] Compared with related technologies, the flywheel energy storage experimental device provided by this utility model has the following beneficial effects:

[0014] This invention provides a flywheel energy storage experimental device. When using this device, the controller controls the drive component to rotate the flywheel. The flywheel then rotates the rotating rod, which in turn rotates the protrusion. When the flywheel reverses, the limiting block restricts the protrusion, effectively preventing the flywheel from reversing. This device adds a function to prevent flywheel reversal. At the end of the device's operation, due to the large inertia and load, a certain degree of reversal may occur. This device effectively prevents the flywheel from reversing when it stops rotating, thus effectively avoiding the impact of alternating torque generated during reversal on the bearings and support structure. It also avoids the loss of flywheel dynamic balance due to reversal, reduces structural damage to the equipment caused by excessive vibration, and ultimately extends the service life of the device.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a flywheel energy storage experimental device provided by this utility model; Figure 2 for Figure 2 The diagram shows a cross-sectional view of the main body of the device. Figure 3 for Figure 2 The diagram shows the internal structure of the fixing block. Figure 4 for Figure 2 The diagram shows an enlarged view of part A. A flywheel energy storage experimental device includes: a main body 1, comprising an anti-reverse component 2, a shock-absorbing component 3, a protective component 4, and a base plate 8. The anti-reverse component 2 includes a device support frame 211 fixedly mounted on the main body 1. A fixing block 201 is provided on the device support frame 211, and a fixing ring 202 is provided on the fixing block 201. An inner ring 209 is provided inside the fixing block 201, and a rotating bearing 203 is provided between the inner ring 209 and the fixing ring 202. A vertical groove 206 is formed on the fixing ring 202, and a limiting slider 205 is provided inside the vertical groove 206. A protrusion 204 is provided on the limiting slider 205. A first elastic element 207 for limiting the slider 205 to reset is provided inside the vertical groove 206. A protrusion 208 is installed on the inner ring 209, and a rotating rod 210 is provided on the inner ring 209.

[0022] The first elastic element 207 mentioned above can be a spring, elastic sponge, or other component that can assist the limiting block 204 in resetting. The device support frame 211 has the function of fixing and supporting the fixing block 201. The rotating rod 210 has the function of driving the inner ring 209 to rotate, thereby driving the protrusion 208 to rotate.

[0023] The damping component 3 includes a guide groove 303 formed on the device base plate 8. A fixed slide rod 306 is provided inside the guide groove 303. A vertical slide rod 304 is provided on the fixed slide rod 306. A damping plate 301 is installed at the top of the vertical slide rod 304.

[0024] The aforementioned guide groove 303 serves to guide the damping plate 301, and the fixed slide rod 306 serves to guide the vertical slide rod 304.

[0025] A second elastic element 305 for damping the anti-reverse component 2 is arranged around the fixed slide rod 306. A guide block 302 is provided inside the guide groove 303, and the guide block 302 is slidably connected to the guide groove 303. The vertical slide rod 304 is slidably connected to the fixed slide rod 306.

[0026] The second elastic element 305 mentioned above can be a spring, elastic sponge, or other element that can absorb shock when the device is subjected to impact.

[0027] The main body 1 of the device is provided with a drive assembly 5, which includes a drive fixing frame 502 mounted on the device base plate 8, and a drive component 501 is fixedly mounted on the drive fixing frame 502.

[0028] The driving component 501 can be a motor, electric motor or other driving device that can drive the flywheel 402 to rotate, and the driving bracket 502 has the function of fixing the driving component 501.

[0029] The protection component 4 includes a flywheel 402 installed at the output end of the drive component 501. A protective shell 401 is provided around the flywheel 402, and heat dissipation holes 403 are provided on the protective shell 401.

[0030] The aforementioned protective shell 401 serves to protect the flywheel 402 from external damage, and also protects the operator and ensures their safety when the flywheel 402 is damaged. The aforementioned heat dissipation holes 403 serve to ensure that the flywheel 402 dissipates heat in a timely manner.

[0031] The main body 1 of the device includes a support assembly 7, which includes a device support rod 701 installed on the bottom of the device base plate 8. An anti-slip component 702 for preventing slippage of the main body 1 is installed on the bottom of the device support rod 701.

[0032] The aforementioned anti-slip component 702 can be a rubber anti-slip mat, a wooden anti-slip mat, or the like, which can prevent the main body 1 of the device from sliding during operation, thereby ensuring the stable operation of the device.

[0033] A controller 6 is installed on the damping plate 301, and the controller 6 has the function of controlling the operation of the main body 1 of the device.

[0034] The working principle of the flywheel energy storage experimental device provided by this utility model is as follows:

[0035] When this device is used, the controller 6 controls the drive component 501 to drive the flywheel 402 to rotate. At this time, the flywheel 402 drives the rotating rod 210 to rotate, which in turn drives the inner ring 209 to rotate. The inner ring 209 then drives the protrusion 208 to rotate. When the protrusion 208 contacts the limiting block 204, the protrusion 208 will press against the limiting block 204. Simultaneously, the limiting block 204 will drive the limiting slider 205 to press against the first elastic element 207. When the protrusion 208 passes the limiting block 204, the first elastic element 207 will use its own elasticity to push the limiting block 204 to reset, thereby ensuring the normal operation of the device. When the flywheel 402 reverses, the limiting block 204 will restrict the protrusion 208, effectively preventing the flywheel from reversing.

[0036] Compared with related technologies, the flywheel energy storage experimental device provided by this utility model has the following beneficial effects:

[0037] When using this device, the controller 6 controls the drive component 501 to drive the flywheel 402 to rotate. At this time, the flywheel 402 drives the rotating rod 210 to rotate, and the rotating rod 210 drives the protrusion 208 to rotate. When the flywheel 402 reverses, the limiting block 204 restricts the protrusion 208, which can effectively prevent the flywheel from reversing. This device adds the function of preventing the flywheel 402 from reversing. When the device ends, due to the large inertia of the load, it may reverse to a certain extent. This device can effectively prevent the flywheel 402 from reversing when it stops rotating, thereby effectively avoiding the impact of the alternating torque generated during reversal on the bearings and support structure, avoiding the dynamic balance of the flywheel 402 caused by reversal, reducing the structural damage to the equipment caused by excessive vibration, and thus extending the service life of the device.
