Description

Technical Field

[0001] The invention relates to the technical field of flywheel energy storage, and in particular to a flywheel assembly for a generator. Background Art

[0002] The flywheel has a large moment of inertia. Since the work done by each cylinder of the engine is discontinuous, the engine speed is also variable. When the engine speed increases, the kinetic energy of the flywheel increases and the energy is stored; when the engine speed decreases, the kinetic energy of the flywheel decreases and the energy is released. The flywheel can be used to reduce the speed fluctuation during the operation of the engine and withstand the impact of alternating loads. At the same time, the flywheel is a high-speed rotating part. Therefore, the flywheel is required to have sufficient rigidity and strength, good ability to withstand impact loads, wear resistance and good lubrication.

[0003] Flywheel energy storage refers to a method of energy storage that uses an electric motor to drive a flywheel to rotate at high speed, and then uses the flywheel to drive a generator to generate electricity when needed. The technical characteristics are high power density and long life. The flywheel body is the core component of the flywheel energy storage system. Its function is to strive to increase the rotor's limit angular velocity, reduce the rotor's weight, and maximize the storage capacity of the flywheel energy storage system. When using a general flywheel energy storage system, the mass of the flywheel cannot be adjusted according to actual needs, but can only increase the speed of the flywheel, which leads to poor stability of the flywheel system and also creates great safety hazards, which cannot meet actual needs.

The auxiliary permanent magnet ring increases the structural stability of the conversion shaft 17 inside the auxiliary shaft 24. When the speed of the flywheel is too fast, it cannot store more electricity. It is necessary to increase the mass of the flywheel and expand the energy storage capacity of the flywheel. A plurality of mass pieces 58 are clamped between the limit seats 57 and are installed on one side of the second flywheel 12 using a fixed threaded rod 56. The mass of the second flywheel 12 is adjusted to increase the appropriate mass of the second flywheel 12. The oil pump 45 is started and the upper solenoid valve 53 on one side of the second auxiliary impeller 52 is opened. The resistance oil in the oil storage tank 48 is drawn out through the oil discharge pipe 49 on the side of the second auxiliary impeller 52, enters the auxiliary shaft 24 through the oil inlet, enters the oil outlet pipe 54 on the side of the second auxiliary impeller 52 through the oil outlet, and enters the cavity on the side of the second auxiliary impeller 52 inside the regulating cylinder 5 through the upper solenoid valve 53. The conversion shaft 17 drives the first auxiliary impeller 51 to rotate, and the blades on the first auxiliary impeller 51 push the resistance oil to flow. The resistance oil impacts the blades on the second auxiliary impeller 52, so that the auxiliary shaft 24 rotates. The rotation of the auxiliary shaft 24 drives the second flywheel 12 to rotate, so that the auxiliary shaft 24 and the first flywheel 11 rotate together, so that the mass on the entire flywheel group is increased. Under certain speed conditions, the mechanical energy of the flywheel group is increased. When the second flywheel needs to be adjusted 12, or when a fault occurs and the first flywheel 11 and the second flywheel 12 need to be stopped, the oil pump 45 is turned on, the upper solenoid valve 53 on the side of the second reduction impeller 55 is turned on, and the resistance oil in the oil storage tank 48 is pumped out through the oil discharge pipe 49 on the side of the second reduction impeller 55, enters the auxiliary shaft 24 through the oil inlet, enters the oil outlet pipe 54 on the side of the second reduction impeller 55 through the oil outlet, and enters the cavity on the side of the second reduction impeller 55 inside the regulating cylinder 5 through the upper solenoid valve 53, the conversion shaft 17 drives the second reduction impeller 55 to rotate, the blades on the second reduction impeller 55 push the resistance oil to flow, and the resistance oil impacts the blades on the first reduction impeller 46, so that the reduction shaft 15 rotates, thereby driving the first reduction wheel 13 and the second reduction wheel 14 to rotate,Since the blades on the first reduction wheel 13 and the second reduction wheel 14 are opposite, the first reduction wheel 13 and the second reduction wheel 14 push the resistance oil inside the reduction cylinder 4 toward each other, and the hydraulic oil is transmitted through the support plate 36 and the guide plate 44, and the hydraulic oil impacts each other, and the flow rate slows down, and impacts the blades on the first reduction wheel 13 and the second reduction wheel 14 respectively, so that the speed of the reduction shaft 15 is quickly reduced. When the deceleration effect is not fast enough, the motor 42 is started, and the output shaft of the motor 42 rotates to drive the threaded rod 39 to rotate, and push the rack 43 to move back and forth, thereby driving the gear 40 and the rotating rod to rotate, so that the position of the guide plate 44 rotates, and the guiding direction of the guide plate 44 to the resistance oil is adjusted, so that the guide plate 44 is perpendicular to the direction of the first reduction wheel 13 or the second reduction wheel 14, so that the deceleration effect of the resistance oil is the best. In addition, the speed of the reduction shaft 15 is extremely fast. At the moment of deceleration, the impact is extremely large. The resistance oil can well buffer the impact caused by the deceleration of the reduction shaft 15, while achieving deceleration, reducing the impact on the equipment.
