Background

The inertial energy storage is a method for storing energy by depending on the motion of an object, and the kinetic energy stored in the rotating machinery and the flywheel is rotating mechanical energy, so that the energy storage density is high, and the extraction is convenient.

The inertial energy storage power generation is a power generation device which utilizes a prime mover to drive a flywheel to rotate at a high speed and then utilizes the flywheel to drive a generator to generate power when needed. When energy is stored, a flywheel is dragged by a prime mover such as a motor, a turbine, a diesel engine and the like to accelerate the energy storage, and the energy is stored in the flywheel rotating at a high speed in a kinetic energy mode, so that the energy storage process of converting electric energy, chemical energy into mechanical energy is completed; when the flywheel reaches the set maximum rotating speed, the prime motor maintains a constant rotating speed; when releasing energy, the flywheel rotating at high speed drags the generator to output current and voltage suitable for load by using the inertia effect of the flywheel, and the energy releasing process from mechanical energy to electric energy conversion is completed.

The single-cylinder diesel engine is widely applied due to simple design and high cost performance, but when used as the power of a generator, the single-cylinder diesel engine can only be driven by a belt generally, and the belt transmission has the problems of large power loss, belt abrasion and unstable frequency, so that the single-cylinder diesel engine is rarely used as the power source of the generator at present, and the problem of high energy consumption exists in a small part of the single-cylinder diesel engine. In addition, because the flywheel starting moment of large inertia is larger, the single cylinder diesel engine in the prior art is a direct starting flywheel, and a diesel engine with output power far larger than the actually required power of a generator is required, so that the cost is higher, the energy consumption of power generation is increased while resources are wasted, a unit is easy to generate heat, and the noise generated during power generation is larger.

The ability of a flywheel to act as an energy store is generally expressed in terms of rotational inertia, with greater rotational inertia storing more energy, but greater rotational inertia may cause the power machine to be less likely to start. Therefore, the traditional integrated disk flywheel is difficult to realize easy starting and large moment of inertia, and is difficult to carry and assemble conveniently due to heavy volume and large diameter.

Furthermore, the input shaft and/or the output shaft of the flywheel are/is connected with the clutch, and the clutch connected in front of the input shaft can be disconnected with the flywheel when the clutch is closed without a single-cylinder diesel engine, so that the energy conservation and the consumption reduction are facilitated; and the clutch is connected behind the output shaft, so that the connection with the generator can be cut off when the engine is started, the starting torque is reduced, the power requirement on the single-cylinder diesel engine is further reduced, and the cost is saved. Furthermore, the integral flywheel is split into a plurality of independent flywheel pieces, and then the fixing pieces are connected in a sliding mode to form the integral flywheel with the energy storage function, so that the problem that the traditional integral flywheel is difficult to assemble, disassemble and transport due to heavy volume and large circle diameter is solved; the flywheel sheet is limited by the elastic body, so that the flywheel sheet is difficult to move outwards due to the resistance limitation of the elastic body at low speed, and can keep lower rotational inertia, and the flywheel sheet moves outwards due to the centrifugal force overcoming the resistance limitation of the elastic body at high speed, so that higher rotational inertia can be obtained, the starting moment is further reduced, and the energy storage capacity is improved; in addition, each flywheel sheet capable of sliding independently can automatically change the inertia of the flywheel under the combined action of centrifugal force and the resistance of the elastic body, so that the amplitude and the phase of the inherent torque fluctuation of the diesel engine are dynamically adapted, and the aim of reducing the torque fluctuation of the diesel engine is fulfilled.

As shown in fig. 2 and 5, after the single cylinder diesel engine 1 is started, the automatic transmission 2 is in the lowest gear and the clutch 7 at the rear end of the output shaft of the flywheel 3 is disengaged, and the automatic transmission 2 converts the high-speed and low-torque output of the single cylinder diesel engine 1 into low-speed and high-torque output to start the flywheel 3 to rotate; when the control system detects that the rotating speed of the output shaft of the flywheel 3 reaches a preset threshold value through the speed sensor 5, the automatic transmission 2 is controlled to be shifted up to increase the rotating speed of the flywheel 3, the steps are repeated until the flywheel 3 is accelerated from a low speed to a rated rotating speed to store energy, and at the moment, the automatic transmission 2 is shifted up to the highest gear to enable the single-cylinder diesel engine 1 to maintain the flywheel 3 at a constant rotating speed with smaller power; when releasing energy, the control system controls the clutch 7 at the rear end of the output shaft of the flywheel 3 to be attracted, the flywheel 3 rotating at a high speed drags the generator 4 to generate electricity by utilizing the inertia effect of the flywheel 3, and current and voltage suitable for loads are output to finish the process of releasing energy from mechanical energy to electric energy conversion. When the flywheel 3 is started, due to the resistance of the elastic body 303 (such as an arc spring), the flywheel piece 302 is positioned at the position close to the center of the flywheel 3, the inertia torque of the flywheel 3 is small at the moment, and the starting force required by the single-cylinder diesel engine 1 is small; as the rotation speed of the flywheel 3 increases, the centrifugal force of the flywheel piece 302 is gradually greater than the resistance of the elastic body 303 (such as an arc spring), and at this time, the flywheel piece 302 moves outwards relative to the center of the fixed disk 301, so that the inertia torque of the flywheel 3 is increased, and the rotational inertia of the flywheel 3 is improved; when the flywheel 3 drives the generator 4 by means of inertia, the flywheel 3 decelerates under the dragging resistance of the generator 4 and the torque decreases, the centrifugal force of the flywheel pieces 302 further increases, so that the flywheel pieces 302 slide outwards along the guide rods 306 of the fixed disc 301, at this time, the centrifugal force and inertia of the flywheel 3 increase under the action of the plurality of flywheel pieces 302, the torque decreasing speed transmitted to the generator 4 decreases, and the time of the output power of the generator 4 can be prolonged.
