Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to an energy-enhancing flywheel mechanism which realizes energy conversion and increases energy output by performing work on a rotating shaft through translation of a flywheel. Background Art

[0002] Flywheel is a common mechanical device, which plays an important role. It is mainly used to store and release energy, achieve energy balance and transfer, and is widely used in various fields. When external energy is input, the flywheel will rotate and store the energy. This energy storage method is efficient and fast, and can absorb a large amount of energy in a short time. Flywheel energy storage system is widely used in power systems and other fields. It can convert electrical energy into mechanical energy through electric motors and then store it in flywheels. When energy needs to be released, the flywheel will convert the stored energy into mechanical energy or electrical energy output to achieve energy balance and transfer.

[0003] Traditional flywheels mainly perform centripetal motion, so the resultant external torque of traditional flywheels is zero, but the resultant external force is not zero, so the angular momentum is conserved; however, the flywheel adds external force to the rotating shaft, which increases the torque of the rotating shaft without doing work, so the angular kinetic energy of the flywheel does not change in the absence of resistance; therefore, by making the external force do work on the rotating shaft, energy conversion is generated, and the energy enhancement effect is achieved, which has become the direction of our research and development. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the utility model provides an energy-enhancing flywheel mechanism, which overcomes the defect that the traditional flywheel only stores and transmits energy but does not do work, and utilizes three hammers to perform rigid body translational motion, the three hammers generate kinetic energy, do work on the rotating shaft, thereby generating energy conversion, and achieving the purpose of energy enhancement;

[0005] The technical solution adopted by the utility model to solve its technical problems is that it includes a thin disc flywheel, a suspended hammer flywheel, a speed reducer, a speed increaser and a rotating shaft, wherein the power input end of the rotating shaft is provided with a speed reducer and a speed increaser, the thin disc flywheel and the suspended hammer flywheel are key-connected with the rotating shaft, the suspended hammer flywheel includes three suspended hammers, a connecting disk, a hub, and three limit pins, the hub is connected to the connecting disk, the three suspended hammers are matched with the connecting disk and connected with the pin shaft, the three limit pins are respectively matched with one side of the three suspended hammers and connected with the connecting disk, the center of the hub is provided with an axial hole connected with the rotating shaft, and the inner diameter of the axial hole is provided with a keyway;

[0006] The three hanging hammers have the same structure and mass, and are evenly distributed on the hanging hammer connection plate at 120 degrees. The main arrows of the three hanging hammers move slightly in one direction, and the main arrows of the hammer heads are not perpendicular to the rotation axis by 90 degrees.

[0007] The angular displacement directions of the three pendulums are consistent with the rotation direction of the rotating shaft.

[0008] The beneficial effect of the utility model is that the energy-enhancing flywheel mechanism overcomes the defect that the traditional flywheel only stores and transmits energy but does not do work. The suspended hammer flywheel is in translation rather than rotation, so it only does work on the rotating shaft without increasing the torque of the rotating shaft. The three hammer heads continuously generate kinetic energy. Therefore, the energy output to the load through the rotating shaft is much greater than the original power input by the motor, thereby achieving the beneficial effect of energy enhancement.

[0013] The specific implementation method of the utility model is, referring to Figure 1 , Figure 2 , Figure 3 , including a thin disc flywheel 5, a suspended hammer flywheel 6, a reducer 2, a speed increaser 3 and a rotating shaft 1, wherein the power input end of the rotating shaft 1 is provided with a reducer 2 and a speed increaser 3, the thin disc flywheel 5 and the suspended hammer flywheel 6 are connected with the rotating shaft 1 keys 4 and 7, the suspended hammer flywheel 6 includes three suspended hammers 8, a connecting disk 9, a hub 11, and three limit pins 14, the hub 11 is connected to the connecting disk 9, the three suspended hammers 8 are matched with the connecting disk 9 and connected with the pin shaft 10, the three limit pins 14 are respectively matched with one side of the three suspended hammers 8 and connected with the connecting disk 9, the center of the hub 11 has an axial hole 12 connected with the rotating shaft 1, and the inner diameter of the axial hole 12 has a keyway 13;

[0014] Reference Figure 3 The three hanging hammers 8 have the same structure and mass, and are evenly distributed on the hanging hammer connecting plate 9 at 120°. The main arrows of the three hanging hammers 8 move slightly in one direction, and the main arrows of the hammer heads are not perpendicular to the rotation axis by 90 degrees.

[0015] Reference Figure 1 , Figure 3 , the angular displacement direction of the three pendants 8 is consistent with the rotation direction of the shaft 1;

[0016] Reference Figure 1, Figure 2 , Figure 3 The working principle of the energy-enhancing flywheel mechanism is to connect the power output shaft of the motor with the power input end of the rotating shaft 1 of the energy-enhancing flywheel mechanism, start the motor to input the original power, and the original power is transformed by the power output shaft of the motor, the reducer 2, and the speed increaser 3, so that the rotation speed of the rotating shaft 1 of the energy-enhancing flywheel mechanism is greater than the rotation speed of the power output shaft of the motor, driving the rotating shaft 1 to rotate, and the input power is obtained and stored by the thin disc flywheel 5. While storing and releasing energy, the thin disc flywheel 5 overcomes the rotation dead point of the suspended hammer flywheel 6, drives the suspended hammer flywheel 6 to rotate smoothly, and outputs it to the load through the rotating shaft 1; because the suspended hammer flywheel 6 is a translation rather than a rotation, it only does work on the rotating shaft without increasing the torque of the rotating shaft 1, and the three suspended hammers 8 continuously generate kinetic energy. Therefore, the energy output to the load through the rotating shaft 1 is much greater than the original power input by the motor, achieving the effect of energy enhancement;

[0019] 1. Moment of inertia: l = ½ mr 2 = ½(62×0.25 2 )=1.9375kg / m 2 ;

[0020] 2. Linear speed: v = ΠD / t = 3.14 × 0.5 × 1500 / 60 = 39.25 m / s;

[0021] 3. Angular velocity: ω=v / r=39.25÷0.25=157 rad / s;

[0022] 4. Angular momentum: L = lω = 1.9375 × 157 = 304.18 kgm 2 / s;

[0023] 5. Angular kinetic energy: EK = ½ lω 2 = ½ (1.9375 × 157 2 ) = 23.879kw; the thin disc flywheel does not do work on the rotating shaft, and the energy cannot be converted;

[0024] 2. Momentum and kinetic energy analysis of suspended hammer flywheel: speed 1500 rpm, number of suspended hammers 3, mass of a single suspended hammer m = 18.3 kg, diameter of suspended hammer D = 0.55 m, total mass of suspended hammer flywheel = 18.3 × 3 = 55 kg;

[0026] 2. Momentum of suspended flywheel: p=mv=55×43.175=2374.625kgm / s;

[0027] 3. Kinetic energy of suspended hammer flywheel: E=½mv 2 = ½ (55 × 43.175 2 ) = 51.262kw;

[0028] 3. Final output power = initial input power of the motor 22 kw + kinetic energy of the suspended hammer flywheel 51.262 kw = 73.262 kw; it can be seen that the output power of the energy-enhancing flywheel mechanism is greater than the input power, that is, the initial input power is 22 kw, and the output is 73.262 kw. Compared with the prime mover, the energy-enhancing flywheel mechanism can drive a larger load.
