Description

 Description

Method for using flywheel battery replenishing gravity driving device capable of automatic clutching

 The present invention relates to the field of flywheel batteries (or flywheel energy storage devices), and more particularly to a device for replenishing energy of a flywheel battery.

Background technique

 Among many energy storage devices, the flywheel battery breaks through the limitations of chemical batteries and uses physical methods to achieve energy storage. When the flywheel rotates at a certain angular velocity, it has a certain kinetic energy, and the flywheel battery is converted into electric energy by its kinetic energy. Compared with chemical batteries, flywheel batteries are expected to be the most promising energy storage batteries due to their high efficiency, short charging time, small relative size, and clean and pollution-free.

 The working principle of the flywheel battery: There is a motor (electric/generator integrated machine) in the flywheel battery. When charging, the motor runs in the form of a motor, and the externally input electric energy is converted into the kinetic energy of the flywheel through the electric motor, that is, the flywheel battery is charged. 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 by the generator, and is output to an external load, that is, the flywheel battery is "discharged". In order to reduce wind loss, friction and other energy losses, the flywheel battery is placed in a vacuum box and uses magnetic suspension bearings to support the rotating parts.

 The flywheel battery has high energy storage density and relatively small size. It is especially suitable for carrying in the field without power supply. Especially for the riders who ride bicycles, it is very necessary to have a laptop, radio, and high-power lighting support. Power flywheel battery. However, the flywheel battery can only drive the motor in the vacuum box to drive the flywheel to rotate, so that the flywheel stores kinetic energy, but there is no power supply in the field to charge the flywheel battery.

detailed description

 The present invention will be further described with reference to the accompanying drawings and specific embodiments. The technical solution of the present invention is mainly to provide a gravity driving mechanism 4 outside the vacuum box 33 of the prior art flywheel battery, and an internal driving in the vacuum box 33 of the flywheel battery. Organization 5 (see Figure 3).

 The function of the gravity driving mechanism 4 is to drive the flywheel 31 to rotate by the gravitational potential energy (see FIGS. 1 to 3), and the flywheel 31 stores the kinetic energy: it includes the weight bag 11, the index rope 12, the pressure roller 14, the pulley 15, and the speed increase. The first pulley 17, the belt 13 and the second pulley 43; the pulley 15 is disposed below the flywheel 31, and the vacuum box 21 is connected to the pulley 15 and the pressure roller 14 through the side plate 26; one end of the index rope 12 and the weight The object bag 11 is connected; the index line 12 is disposed in a gap between the groove 151 of the pulley and the pressure roller 14. The function of the pressure roller 14 is to press the indexing rope 12 into the groove 151 of the pulley 15, increasing the friction force, so that the indexing rope 12 effectively drives the pulley 15 to rotate. Bearings (not shown) can be placed in the pressure roller 14 to avoid unnecessary power consumption; the indexing rope 12 is preferably made of lightweight nylon material. Metal chain sprocket sets are not used here because they reduce the load on the road.

 (See FIGS. 3 to 5) The pulley 15, the speed increaser 16, the first pulley 17, the belt 13 and the second pulley 43 are sequentially connected; the second pulley 43 is disposed on the central shaft 432 outside the vacuum box; The second pulley 43 is provided with a plurality of first magnets 431 along the circumference.

 Preferably, the weight bag 11 can accommodate stones, dirt, or water that are easily found in the field as gravity. Therefore, the weight bag 11 is preferably made of a light, impervious material so that when heavy solids are not found nearby, water, or dirt, or stones can be placed in the weight bag as gravity.

 A ratchet assembly 9 (see Figs. 3 and 6) is disposed between the pulley 15 and the input shaft of the speed increaser 16.

 Referring to Fig. 4, the inner drive mechanism 5 is disposed in the vacuum box 33. The device mainly receives the magnetic force of the gravity drive mechanism and rotates according to the rotation of the gravity drive mechanism. The inner driving mechanism includes a magnetic wheel 51, a rotating shaft 52, a centrifugal mechanism 53 and a friction concave wheel 54, and the magnetic wheel 51 is connected to the centrifugal mechanism 53 via the rotating shaft 52; the sliding sleeve 535 in the centrifugal mechanism 3 passes through the connecting rod 537 and the friction concave wheel 54. A compression spring 536 is disposed between the sliding sleeve 535 and the friction cam 54 . The sliding sleeve 535 can move on the rotating shaft 52. The magnetic wheel 51 is coaxial with the second pulley 43. The magnetic wheel 51 is provided with a plurality of blocks along the circumference. The second magnet 511; the second magnet 511 on the magnetic wheel is equal in number to the first magnet 431 in the second pulley, and corresponds to one another and passes through the magnetic field lithium A

 One end of the flywheel 31 is connected to the generator 34, and the other end is connected to a friction cam 32, and the friction cam 32 is intermittently connected to the friction cam 54 in the inner driving mechanism 5.

The centrifugal mechanism 53 is a mechanical automatic control device based on the principle of centrifugal motion. The structure is as shown in Figs. 4 and 5: On the rotating shaft 52, two first pull rods 531 are respectively provided with two flying hammers 532. The first pull rod 531 is swingable about the pin shaft 533 in a vertical plane. When the rotating shaft 52 rotates, the flying hammer 532 generates a centrifugal movement tendency, and the first pulling rod 531 is opened at a certain angle. The second pull rod 534 moves the sliding sleeve 535 sleeved on the rotating shaft 52 a distance toward the friction cam 32. The friction cam 32 is coupled to the flywheel 31, and the other end of the flywheel 31 is coupled to the generator 34. The greater the rotational speed of the rotating shaft 52, the larger the opening angle of the first pull rod 531, the larger the sliding sleeve 535 is moved against the resistance of the compression spring 536, and the sliding sleeve 535 is connected to the friction concave wheel 54 through the connecting rod 537 (see FIG. 5). The friction cam 54 approaches and engages the friction cam 32, causing the flywheel 31 to rotate therewith, and the flywheel 31 begins to store kinetic energy.

 Instructions:

 Method 1. See Figure 1 to Figure 3 to hang the gravity drive unit at a high position. In the wild, it is often possible to hang a gravity drive on a tree or piling on a steep mountain wall.

 Then, the traction rope 12 is pulled, and the traction weight bag 11 is brought up close to the pulley 15; since the ratchet assembly 9 is provided between the pulley 15 and the speed increaser 16 (see Figs. 3 and 6), the weight bag 11 is pulled upward. When the pulley 15 is in the idling state, the pulling is not laborious; and when the weight bag 11 is lowered, the pulley 15 acts on the ratchet assembly 9, and the ratchet assembly 9 meshes with the input shaft 161 of the speed increaser 16 to drive the speed increaser 16 and related connecting parts rotate.

 After the weight bag 11 is raised (see FIGS. 2 and 3), the traction rope 12 is released, and the weight bag 11 starts to fall by gravity. During the falling of the weight bag 11, the pulley 15 is driven to rotate by the traction rope 12. The speed increaser 16 increases the rotational speed of the pulley 15, the output end 163 of the speed increaser 16 drives the first pulley 17 to rotate, and the first pulley 17 drives the second pulley 43 through the belt 13, and the first magnet 431 of the second pulley 43 The second magnet 511 on the magnetic wheel 51 is coupled by a magnetic field, so that the second pulley 43 drives the magnetic wheel 51, the centrifugal mechanism 53 and the friction cam 54 to rotate together. When the rotation of the centrifugal mechanism 53 reaches a certain speed, the centrifugal force Under the action, the sliding sleeve 535 in the centrifugal mechanism 53 is moved toward the friction cam 32 against the elastic force of the compression spring 536, thereby engaging the friction cam 54 coupled with the sliding sleeve 535 with the friction cam 32, thereby driving the flywheel 31. Rotate to store energy.

 When the weight bag 11 falls to the ground, the traction rope 12 stops moving, so that the pulley 15, the speed increaser 16, the first pulley 17, the belt 13, the second pulley 43, the magnetic wheel 51, the centrifugal mechanism 53, and the friction cam 54 thus stops rotating; the centrifugal force of the centrifugal mechanism disappears, and the elastic force of the compression spring 536 pushes the sliding sleeve 535 such that the friction cam 54 connected to the sliding sleeve 535 leaves the friction cam 32; the flywheel 31 continues to rotate by the stored kinetic energy.

 When the outside world needs electric energy, the kinetic energy of the flywheel 31 is converted into electric energy by the generator 34 and output to an external load.

Fig. 7 is another embodiment of the present invention. It is characterized by the vertical setting of the components inside and outside the vacuum box.
