Abstract

A gravitational potential energy device for replenishing a flywheel battery with energy by gravity comprises a flywheel battery and a gravity-driven device (4) outside the flywheel battery. The electricity generated by an electric generator (17) in the gravity-driven device (4) is input to an electric motor/electric generator (34) in a vacuum box (33) to drive a flywheel (31) to rotate. The method of utilization of the device includes hanging the gravitational potential energy device and a heavy bag (11) thereof at an elevated position. The heavy bag (11) during the falling process drives a belt wheel (15) to rotate via a traction rope (12). A speed regulator increases the rotating speed of the belt wheel (15) and drives the electric generator (17) to generate electricity, and the electricity generated drives the electric motor/electric generator (34) in the vacuum box (33). Then, the electric motor/electric generator (34) drives the flywheel (31) to rotate. The flywheel (31) stores energy by rotating. When no electrical power source is available, kinetic energy can be replenished for the flywheel battery using gravity, so that the flywheel battery can be used for power supply when camping and during travel the next day.

Description

Description Gravity potential energy device for supplementing flywheel battery energy by gravity power generation and method of use

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 by 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 a high energy storage density and a relatively small size. It is especially suitable for carrying in the field without power supply. Especially for bicycles or hikers, when camping in the wild, it is necessary to have a laptop computer and a radio. High-powered lights support the flywheel battery of electricity. However, the flywheel battery can only be driven by the generator 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 below in conjunction with the accompanying drawings and specific embodiments:

The technical solution of the present invention mainly provides a gravity driving mechanism 4 outside the vacuum box 33 of the prior art flywheel battery (see figure

3).

The function of the gravity driving mechanism 4 is to drive the flywheel 31 to rotate by gravity potential energy (see FIGS. 1 to 3), so that the flywheel 31 stores kinetic energy: it includes a weight bag 11, an index rope 12, a pressure roller 14, a pulley 15, and a tone. Speedometer 16, generator 17; pulley 15 is disposed under vacuum box 33, vacuum box 33 is connected to pulley 15 and pressure wheel 14 through side plate 26; one end of indexing rope 12 is connected with weight bag 11; index rope 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 string 12 into the groove 151 of the pulley 15, increasing the frictional force and causing the indexing rope 12 to effectively rotate the pulley 15. 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. Metal chain sprocket sets are not used here because they reduce the load on the road.

(See Fig. 3) The pulley 15, the governor 16, and the generator 17 are connected in sequence; the generator 17 is connected to the motor/generator 34 in the vacuum box through the wire 18;

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 can be placed in the weight bag. Or earth, or stone, as gravity.

A ratchet assembly 9 (see figure) is provided between the pulley 15 and the input shaft 161 of the governor 16.

Instructions:

See Figure 1. The gravity potential device of the present invention is suspended at a high position. In the wild, gravitational potential devices can often be hung on trees or piling on steep mountain walls.

Then, the traction rope 12 is pulled, and the traction weight bag 11 approaches the pulley 15 upward; since the ratchet assembly 9 is disposed between the pulley 15 and the governor 16 (see FIGS. 3 and 4), 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 governor 16, driving the governor 16 and generator 17 rotate to generate electricity.

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 governor 16 increases the rotational speed of the pulley 15, the governor 16 drives the generator 17 to generate electricity, and the generated electric motor drives the motor/generator 34 in the vacuum box, and the motor/generator 34 drives the flywheel 31 to rotate, thereby making the flywheel 31 rotating storage energy;

When the weight bag 11 falls to the ground, the traction rope 12 stops moving, so that the pulley 15, the governor 16, and the generator 17 stop rotating, and 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.
