The working principle of the flywheel battery: There is a motor (electric/generator integrated machine) in the flywheel battery. When charging, the motor operates in the form of a motor, and the electric energy input from the outside is converted into the kinetic energy of the flywheel through the motor and stored. That is, the flywheel battery "charging "; when the outside world needs electric energy, the motor rotates in the form of a generator, and the kinetic energy of the flywheel is converted into electric energy through the generator, which is output to the external load, that is, the flywheel battery is "discharged". In order to reduce windage loss, friction and other energy losses, the flywheel battery is placed in the vacuum box, and the rotating parts are supported by magnetic suspension bearings. the

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

Method 1, the technical solution of the present invention is mainly that an elastic driving mechanism and an automatic separation mechanism are set outside the flywheel battery vacuum box 21 of the prior art, and a magnetic drive wheel 23 connected to the flywheel 22 is added in the vacuum box 21 of the flywheel battery ( See Figure 3).

The function of the elastic driving mechanism is to use the elastic potential energy to drive the flywheel 22 to rotate (see Figures 1 to 5), so that the flywheel 22 stores kinetic energy: it includes the first positioning pile 18, the second positioning pile 19, the elastic rope assembly 11, and the index rope 12 , limit assembly 13, pressure wheel 14, pulley 15, speed increaser 16, first friction wheel 17, second friction wheel 43; the first end 111 of elastic cord assembly 11 is connected with index rope 12, and the second end 112 Connect with the second positioning pile 19 fixed on the ground; the first positioning pile 18 is fixed on the ground at a certain distance from the second positioning pile 19, and is connected with the vacuum box 21; the belt pulley 15 is arranged on the bottom of the vacuum box 21 (see 5), the vacuum box 21 is connected to the pulley 15 and the pressure wheel 14 through the side plate 26; one end of the index rope 12 is connected to the first end 111 of the elastic cord assembly 11, and the other end is connected to the limit assembly 13 (see FIG. 1 and FIG. 2 ); the index rope 12 is set in the gap between the groove 151 of the pulley and the pressure roller 14 . The function of the pressing wheel 14 is to compress the index rope 12 in the groove 151 of the pulley 15 to increase the friction force so that the index rope 12 can effectively drive the pulley 15 to rotate. Bearings (not shown) can be arranged in the pressure roller 14 to avoid unnecessary power consumption; the index rope 12 is preferably made of lightweight nylon material. The metal chain sprocket is not used here because it reduces the load on the road. the

The elastic cord assembly 11 mainly includes a first end 111, a plurality of elastic cords 113 and a second end 112. The first end 111 is connected to the second end 112 through the elastic cords 113. The most commonly used materials for making the elastic cords 113 are polyester and high elastic yarns. , Light texture, easy to carry. The reason why the elastic cord assembly 11 does not use heavy metal springs is also to reduce the load during the journey. the

(see Fig. 5 to Fig. 7) pulley 15, speed increaser 16, first friction wheel 17 and second friction wheel 43 are connected sequentially; The friction wheel 43 is provided with a plurality of magnets 431 along the circumference; a ratchet assembly 9 is provided between the pulley 15 and the input shaft 161 of the speed increaser 16 (see Figure 5 and Figure 14);

Referring to FIG. 1 and FIG. 16 , the limit assembly 13 includes a striker 131 , a limit spring 132 and a fixed block 133 . The collision block 131 can slide on the traction rope 12 , and the fixed block 133 is fixed on the traction rope 12 . A limit spring 132 is disposed between the collision block 131 and the fixed block 133 .

See Fig. 5 and Fig. 6, in the vacuum box 21 of described flywheel battery, flywheel 22 is connected with a magnetic wheel 23, and magnetic wheel 23 is provided with a plurality of magnets 231 along the circumference; The number of magnets 431 on 43 is equal, and one-to-one correspondence, and through magnetic field coupling; In order to reduce friction consumption, a plurality of rolling balls 182 are arranged on the end face of the second friction wheel, see Figure 7, correspondingly, outside the vacuum box, A chute 211 for the running of the rolling ball 182 is provided; the magnetic drive wheel 23 is coaxial with the second friction wheel 43; Made of magnetic material, to avoid the operation of the magnetic wheel 23 and the second friction wheel 43 from being disturbed. the

(See Figures 3 to 9) The function of the automatic separation mechanism is: after the second friction wheel 43 drives the magnetic wheel 23 to rotate, it can automatically stay away from the magnetic wheel 23, otherwise the magnet 431 on the second friction wheel 43 will be opposite to the rotating magnet. The magnetic wheel 23 of the flywheel 23 produces resistance, which will consume the kinetic energy of the flywheel 22. The automatic separation mechanism includes a guide bolt 31, a first return spring 32, a wedge push rod mechanism 33 (see Figure 9), and a sliding rod 34; the upper part of the sliding rod 34 is connected with the vacuum box 21, and the guiding bolt 31 is arranged on the upper part of the sliding rod 34; The first return spring 32 is arranged inside the guide bolt 31, and its effect is that when the external force causes the guide bolt 31 to move toward the direction of the magnetic wheel 23, the first return spring 32 is pressed, and when the external force acting on the guide bolt 31 disappears, the first The return spring 32 returns the guide bolt 31 . A second friction wheel 43 is arranged outside the guide bolt 31 . The guide bolt 31 includes a slope 311 , an optical axis 312 and a thread 313 . The slope 311 is provided for wedging of the wedge 333 (see FIG. 7 and FIG. 9 ). The optical axis 312 is for the small diameter of the screw hole 183 of the second friction wheel 43 to rotate on the optical axis 312 . When the screw thread 313 of the guide bolt 31 enters the screw hole 183 of the second friction wheel 43 in rotation, the second friction wheel can rotate around the screw thread 313 until it rotates out of the screw thread 313 and slides down from the sliding bar 34 to the ground. the

Referring to Fig. 8 and Fig. 9, the wedge push rod mechanism 33 mainly includes a second return spring 331, a push rod 332, and a wedge 333. When the bumper 131 pushes the push rod 332 (at this time, the second return spring 331 is under pressure), the wedge 333 connected to the push rod 332 is wedged into the slope 311 of the guide bolt, forcing the guide bolt 31 to move toward the direction of the magnetic wheel 23; After the bumper 131 leaves the push rod 332, the second return spring 331 restores the push rod 332 to the position before being pushed. the

Instructions:

Method 1. See Figures 5 to 7, rotate the second friction wheel 43 through the thread 313 of the guide bolt 31, and install it on the optical axis 312 of the guide bolt 31; (see Figure 1) drive the first friction wheel 43 on the ground Positioning pile 18 and the second positioning pile 19, the first positioning pile 18 is at a certain distance from the second positioning pile 19; then the elastic driving device is placed on the ground, and the first positioning pile 18 is connected with the vacuum box 21 of the flywheel battery; the second positioning The stake 19 is connected to the second end 112 of the elastic cord assembly. At this moment, the elastic cord 113 is in the minimum tension state; then the traction cord 12 is pulled, and the first end 111 of the traction elastic cord assembly 11 overcomes the elastic force of the elastic cord 113 and gradually approaches the belt. Pulley 15 (see Figure 2); since the ratchet assembly 9 (see Figure 5 and Figure 14) is set between the pulley 15 and the speed increaser 16, when one end of the elastic cord assembly 11 is pulled upward, the pulley 15 is idle and when the elastic cord assembly 11 is contracted by the elastic force of the elastic cord 113, the pulley 15 reversely rotates to act on the ratchet assembly 9, and the ratchet assembly 9 engages with the input shaft 161 of the speed increaser 16 to drive the speed increaser. The gearbox 16 and associated connecting parts rotate.

When the first end 111 of the elastic cord assembly is close to the pulley 15;, the elastic cord 113 is elongated, and the elastic cord 113 on the elastic cord assembly is in the maximum tension state, that is, the elastic potential energy is in the maximum state (see Figure 2);

Then, let go of the traction rope 12, and the elastic cord assembly 11 begins to shrink gradually by the elastic force of the elastic cord 113. During the contraction process, the elastic cord assembly 11 drives the belt pulley 15 to rotate by the traction rope 12, and the speed increaser 16 drives the belt pulley 15 to rotate. The rotating speed increases, and the output end 163 of the speed increaser 16 drives the first friction wheel 17 to rotate, and the first friction wheel 17 drives the second friction wheel 43, and the magnet 431 on the second friction wheel 43 and the magnetic drive wheel 23 in the vacuum box 21 The magnet 231 of the magnet 231 is coupled by a magnetic field, so that the second friction wheel 43 drives the magnetic wheel 23 and the flywheel 22 to rotate, and the flywheel 22 stores kinetic energy during rotation;

When the elastic potential energy of the contraction of the elastic rope assembly 11 gradually decreases, the elastic rope 113 gradually shortens, and the bumper 131 of the limit assembly on the traction rope 11 contacts with the push rod 332 (see Fig. 1, Fig. 4, Fig. 8, Fig. 9 and Figure 16). At this time, the flywheel 22 in the vacuum box 21 has stored enough kinetic energy, and the flywheel 22 can actually drive the second friction wheel 43 to rotate through the magnetic wheel 23 . Therefore, the very small shrinkage elastic force of the elastic rope 113 can make the limit spring 132 behind the bumper 131 be gradually compressed, and the elastic force generated by the limit spring 132 pushes the push rod 332 through the bumper 131, and the wedge connected with the push rod 332 333 is wedged into the slope 311 of the guide bolt, so that the guide bolt 31 moves axially toward the direction of the magnetic wheel 23, as shown in Figure 7 (the flat key 39 makes the guide bolt 31 only allow axial movement); thus, the thread of the guide bolt 313 is engaged with the screw hole 183 of the rotating second friction wheel 43, see Fig. 11 and Fig. 13 . At this time, the rotational force of the second friction wheel 43 mainly comes from the magnetic wheel 23 driven by the flywheel 22 , and the magnetic wheel 23 is coupled with the magnetic field of the second friction wheel 43 to drive the second friction wheel 43 to rotate. Then, the second friction wheel 43 continues to rotate, and the rotation at this time is around the thread 313 of the guide bolt, so at last the second friction wheel 43 can rotate out of the thread 313 of the guide bolt, and slide down from the slide bar 34 to On the ground; thus the second friction wheel 43 is far away from the magnetic wheel 23 (see the dotted line in FIG. 4 ), and the magnetic force of its magnet 431 no longer produces resistance to the magnetic wheel 23 . Then the flywheel 22 can continue to rotate by virtue of the stored kinetic energy in the vacuum in the vacuum box 21;

When the outside world needs electric energy, the kinetic energy of the flywheel 22 is converted into electric energy by the generator 25 and output to the external load.

Method 2. When the flywheel 22 still has residual kinetic energy, the stop magnet 27 can be inserted into the stop groove 28 on the vacuum box (see Figure 15), and the magnet 231 in the magnetic wheel 23 in the vacuum box is subjected to the magnetic force of the stop magnet 27 , so that the magnetic wheel 23 and the flywheel 22 gradually stop rotating; then the second friction wheel 43 is installed on the optical axis 213 of the guide bolt; the rest is the same as method 1. the
