Description

Technical Field

[0001] The present invention relates to the technical field of flywheel energy storage, and particularly to a flywheel energy storage braking energy recovery system and method. Background Art

[0002] A flywheel is a disk-shaped part with a large moment of inertia, and its function is like an energy storage device. For a four-stroke engine, it does work once every four piston strokes, that is, only the power stroke does work, while the exhaust, intake, and compression strokes all consume power. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft;

[0003] During the process of flywheel braking, the stored mechanical energy will be wasted during braking. In the existing flywheel energy storage system during braking, the energy storage system is used to absorb the energy during flywheel braking, and the energy absorbed by the energy storage system will be dissipated in the form of heat energy, resulting in energy waste.

[0022] A flywheel energy storage braking energy recovery method includes the following steps:

[0023] S1: The driving component transmits the collected mechanical force to the surface of the flywheel through the contact component and pushes the flywheel to rotate, reducing the mechanical force required for the flywheel to start again.

[0024] S2: The flywheel rotates inside the arc friction frame. At the same time, the arc friction frame is limited by the pressure during rotation. The mechanical force during the braking of the flywheel is recovered by the movement of the arc friction frame.

[0025] S3: When the elastic sheet moves, it pushes the force-receiving ring to rotate on the surface of the rotating rod. The mechanical force during the braking of the flywheel is collected by the rotation of the rotating ring and the force-receiving ring.

[0026] S4: The telescopic elastic rod can push the bent rod to move. When the bent rod moves, it pushes the flywheel to start rotating through the contact component, converting the recovered mechanical force into the mechanical force required for the flywheel to start.

[0027] The present invention has the following beneficial effects:

[0028] In the present invention, a recovery component is arranged inside the outer shell. When the flywheel rotates, it drives the recovery component to rotate inside the outer shell through friction. After the flywheel completes the braking work, the recovery component stops synchronously with the flywheel through friction. The recovery component uses the pressure generated during the rotation of the flywheel to push the transmission component to deform, and the transmission component transmits the mechanical force of the flywheel braking to the driving component through deformation. When the flywheel starts to work again, the driving component transmits the collected mechanical force to the surface of the flywheel through the contact component and pushes the flywheel to rotate, reducing the mechanical force required for the flywheel to start again, thereby achieving the purpose of recycling the braking energy of the flywheel.

[0029] When the flywheel of the present invention rotates inside the outer shell through the rotating rod, the flywheel will generate friction with the inner wall of the arc friction frame during rotation. The arc friction frame drives the sliding frame to move through friction, and the sliding frame drives the fixed ring to rotate inside the outer shell through the bracket. When the arc friction frame drives the fixed ring to reach a certain position, the flywheel will rotate inside the arc friction frame, and at the same time, limit the arc friction frame through the pressure during rotation, and use the movement of the arc friction frame to recover the mechanical force during the braking of the flywheel.

[0030] When the sliding frame moves, it drives the fixed rod to move through the central frame. When the fixed rod moves, it drives the rotating ring to rotate on the surface of the rotating rod through the connection between the arc plate and the vertical rod. The rotating ring drives the slider to slide inside the arc chute frame through the vertical rod, improving the stability of the rotating ring during rotation. When the vertical rod moves, it drives the elastic sheet to move inside the outer shell through the push rod. When the elastic sheet moves, it drives the force-receiving ring to rotate on the surface of the rotating rod, and uses the rotation of the rotating ring and the force-receiving ring to collect the mechanical force during the braking of the flywheel.

[0031] When the force-receiving ring rotates, it drives the moving block to slide inside the semi-circular chute frame by squeezing the elastic sheet. When the moving block moves, it drives the arc spring frame to deform through the cylindrical rod, and drives the telescopic spring rod to squeeze the surface of the base through the arc spring frame. The contraction of the telescopic spring rod is used to recover and store the mechanical force of the flywheel. When the flywheel needs to start again, the electric rod pulls the support frame away from the surface of the base, so that the telescopic spring rod can drive the bent rod to move. When the bent rod moves, it drives the flywheel to start rotating through the contact component, and converts the recovered mechanical force into the mechanical force required for the flywheel to start.

[0032] When the flywheel rotates, it drives the pressure plate to move. When the pressure plate moves, it drives the extrusion elastic sheet to deform, avoiding affecting the use of the flywheel. When the pressure plate needs to transmit and use the recovered mechanical force, the pressure plate will drive the flywheel to rotate, and the pressure plate will be positioned by the extrusion of the contact plate, so that the recovered mechanical force can assist the flywheel to start working through the pressure plate.

[0033] Of course, it is not necessary for any product implementing the present invention to achieve all of the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The arc friction frame 25 pushes the sliding frame 21 to move through friction, and the sliding frame 21 pushes the fixed ring 20 to rotate inside the outer shell 2 through the bracket 23. When the arc friction frame 25 is driven to a certain position where the fixed ring 20 reaches, the flywheel 5 will rotate inside the arc friction frame 25, and at the same time, limit the arc friction frame 25 through the pressure during rotation, and utilize the movement of the arc friction frame 25 to recover the mechanical force during the braking of the flywheel 5.

In the present invention, when the flywheel 5 rotates, it pushes the pressure plate 62 to move. When the pressure plate 62 moves, it pushes the squeezing elastic sheet 61 to deform, so as not to affect the use of the flywheel 5. When the pressure plate 62 needs to transmit and use the recovered mechanical force, the pressure plate 62 will push the flywheel 5 to rotate, and the pressure plate 62 will be positioned by the extrusion of the contact plate 63, so that the recovered mechanical force can assist the flywheel 5 to start working through the pressure plate 62.

[0066] A flywheel energy storage braking energy recovery method includes the following steps:

[0067] S1: The driving component 12 transmits the collected mechanical force to the surface of the flywheel 5 through the contact component 13 and pushes the flywheel 5 to rotate, reducing the mechanical force required for the flywheel 5 to start again.

[0068] S2: The flywheel 5 rotates inside the arc friction frame 25. At the same time, the arc friction frame 25 is limited by the pressure during rotation, and the mechanical force during the braking of the flywheel 5 is recovered by the movement of the arc friction frame 25.

[0069] S3: When the elastic sheet 40 moves, it pushes the force-bearing ring 38 to rotate on the surface of the rotating rod 6, and the mechanical force during the braking of the flywheel 5 is collected by the rotation of the rotating ring 30 and the force-bearing ring 38.

[0070] S4: The telescopic elastic rod 49 can push the bent rod 51 to move. When the bent rod 51 moves, it pushes the flywheel 5 to start rotating through the contact component 13, and converts the recovered mechanical force into the mechanical force required for the flywheel 5 to start.

[0071] In use, a recycling component 10 is arranged inside the outer shell 2. When the flywheel 5 rotates, it drives the recycling component 10 to rotate inside the outer shell 2 through friction. After the flywheel 5 completes the braking work, the recycling component 10 stops synchronously with the flywheel 5 through friction. The recycling component 10 uses the pressure generated during the rotation of the flywheel 5 to push the transmission component 11 to deform. The transmission component 11 transmits the mechanical force of the flywheel 5 braking to the driving component 12 through deformation. When the flywheel 5 starts working again, the driving component 12 transmits the collected mechanical force to the surface of the flywheel 5 through the contact component 13 and pushes the flywheel 5 to rotate, reducing the mechanical force required for the flywheel 5 to start again, thereby achieving the purpose of recycling the braking energy of the flywheel 5. When the flywheel 5 rotates inside the outer shell 2 through the rotating rod 6, the flywheel 5 will generate friction with the inner wall of the arc friction bracket 25 during rotation. The arc friction bracket 25 drives the sliding bracket 21 to move through friction. The sliding bracket 21 pushes the fixed ring 20 to rotate inside the outer shell 2 through the bracket 23. When the arc friction bracket 25 is driven to a certain position of the fixed ring 20, the flywheel 5 will rotate inside the arc friction bracket 25 and limit the arc friction bracket 25 through the pressure during rotation, and recover the mechanical force of the flywheel 5 during braking by using the movement of the arc friction bracket 25. When the sliding bracket 21 moves, it pushes the fixed rod 36 to move through the central bracket 26. When the fixed rod 36 moves, it drives the rotating ring 30 to rotate on the surface of the rotating rod 6 through the connection between the arc plate 35 and the vertical rod 33. The rotating ring 30 pushes the slider 32 to slide inside the arc chute bracket 31 through the vertical rod 33, improving the stability of the rotating ring 30 during rotation. When the vertical rod 33 moves, it pushes the elastic piece 40 to move inside the outer shell 2 through the push rod 34. When the elastic piece 40 moves, it pushes the force-receiving ring 38 to rotate on the surface of the rotating rod 6, and collects the mechanical force of the flywheel 5 during braking by using the rotation of the rotating ring 30 and the force-receiving ring 38. When the force-receiving ring 38 rotates, it pushes the moving block 45 to slide inside the semi-circular chute bracket 44 through the extrusion elastic piece 43. When the moving block 45 moves, it pushes the arc elastic bracket 46 to deform through the cylindrical rod 50, and pushes the telescopic elastic rod 49 to squeeze the surface of the base 55 through the arc elastic bracket 46, and recovers and stores the mechanical force of the flywheel 5 by using the contraction of the telescopic elastic rod 49. When the flywheel 5 needs to start again, the electric rod 54 pulls the support frame 56 away from the surface of the base 55, so that the telescopic elastic rod 49 can push the bent rod 51 to move. When the bent rod 51 moves, it pushes the flywheel 5 to start rotating through the contact component 13, and converts the recovered mechanical force into the mechanical force required for the flywheel 5 to start. When the flywheel 5 rotates, it pushes the pressure plate 62 to move. When the pressure plate 62 moves, it pushes the extrusion elastic sheet 61 to deform to avoid affecting the use of the flywheel 5. When the pressure plate 62 needs to transmit and use the recovered mechanical force, the pressure plate 62 will push the flywheel 5 to rotate, and the pressure plate 62 will be positioned by the extrusion of the contact plate 63, so that the recovered mechanical force can assist the flywheel 5 to start working through the pressure plate 62.
