Description

energy generator

technical field

The present invention relates to an energy generator. More specifically, the present invention relates to a device for converting rotational energy into electrical energy in an efficient manner.

Background technique

With the expansion of the global population and the increasing industrialization of developing countries, the demand for energy has reached unprecedented levels, and the current energy supply is likely to be the source of an energy crisis. To date, more than half of the energy supply comes from fossil fuels extracted from deep within the Earth's crust. Fossil fuels are classified as non-renewable energy because such resources will eventually be depleted on Earth through constant exploration and use. Other types of non-renewable energy sources may include, but are not limited to, nuclear fuels such as coal, oil, natural gas, and uranium. In addition, the consumption and use of many non-renewable energy sources such as fossil fuels and nuclear fuels will generate by-products that also pollute the environment.

To meet our daily electricity needs while reducing our environmental impact, various technologies have been developed to generate electricity from renewable energy sources such as sunlight, wind and ocean waves. The supply of renewable energy is virtually limitless and can be harnessed in a number of ways to greatly reduce or minimize the impact on the environment and Earth's ecosystems. A worrying problem in the renewable energy sector, however, is that power generation is heavily dependent on natural resources beyond human control. For example, if the wind speed is low, the windmill will not work, resulting in zero power flow to the grid. On the other hand, too much wind can damage generators, so a delicate balance needs to be maintained to maintain continuous power generation. Uncertainties in energy production in renewable energy technologies are affecting their viability and commerciality in the energy sector.

With such a limited energy supply, it needs to be fully utilized through a system that converts it efficiently into electricity. The present invention provides such a system and apparatus therefor.

Referring to Figure 1, a preferred embodiment of a rotary energy generator is shown. Although the present invention can be implemented in many different ways and incorporate a variety of different components and techniques, various embodiments of the present invention are based on the combination of two main concepts: first, the law of conservation of angular momentum, and second , the gear ratio. Another aspect of the rotary energy generator is that the torque of at least one of the flywheels is maximized by magnetically levitating the flywheels, since frictional forces can be greatly reduced or even eliminated.

The key components of the rotary energy generator include a rotatable flywheel assembly (10), one or more support rails (21, 22), a drive motor (30) and a generator (40). Preferably, the rotatable flywheel assembly (10) comprises a first flywheel (11) and a second flywheel (12), the first flywheel (11) and the second flywheel (12) are connected with the shaft (13), so Said shaft (13) is rotatable about a first axis (51) to form a rotational movement (52) of the two flywheels (11, 12). The first and second flywheels (11, 12) are efficient rotating mechanisms for storing rotational energy when they are respectively in rotational motion (13), and they are further configured to release the stored rotational energy at a later stage. The amount of energy stored in the first and second flywheels (11, 12) is proportional to their respective weight and rotational speed.

The main function of the support rails (21, 22) is to suspend the flywheel assembly (10) on the ground, and allow the flywheel assembly (10) to rotate in a full rotation manner, so that the flywheel (11, 12) and the support rails (21, 22) friction between them is minimized. In a preferred embodiment, the edge and support rails (21, 22) of each flywheel (11, 12) are magnetized to provide magnetic levitation to eliminate friction. However, it should be noted that magnetic levitation can easily be replaced by other levitation methods as technology develops. One or more rollers may be provided on each support track (21, 22) for contact with the corresponding flywheel (11, 12). The rollers can periodically rotate in a direction that keeps the flywheels (11, 12) in continuous rotation. Preferably, four rollers are provided on each support track (21, 22) and they are equally spaced along the respective support track (21, 22).

A one-way bearing (63) may be provided between the drive motor (30) and the shaft (13) to allow free movement in the opposite direction to the rotational movement (52) of the flywheel assembly (10) so that even when the drive motor ( 30) The shaft (13) can also continue to rotate when closed. The drive motor (30) can be driven by renewable energy or non-renewable energy (eg biomass, hydropower, geothermal, wind, solar, fossil fuel, nuclear fuel, etc.). The drive motor (30) may be fitted with a timer switch that controls its power on/off at pre-programmed intervals for maximum efficiency. The optimal interval is the combination that requires the least energy input to produce the highest net power output.

The rotational motion of the first flywheel (11) drives the first connecting rod shaft (43) to rotate in the first direction (54), and the rotational motion of the second flywheel (12) drives the second connecting rod shaft (44) to rotate in the first direction (54) Rotation in the opposite second direction (56). A reverse gear (81) may be coupled to either the first link shaft (43) or the second link shaft (44) to facilitate reverse rotation (54, 56) of the first and second link shafts (43, 44) ), so that the stator (42) and the rotor (41) can rotate in opposite directions (54, 56), respectively.

In a preferred embodiment, the shaft (13) may be formed by a first shaft (14) and a second shaft (15) connected in a telescopic manner. The first shaft (14) can be connected to the first flywheel (11) through a first one-way bearing (61), the second shaft (15) can be connected to the second flywheel (12) through a second one-way bearing (62), The first and second flywheels (11, 12) can continue to rotate without the driving force of the driving motor (30).

In another preferred embodiment, the shaft (13) further comprises a third connecting rod shaft (94) and a fourth connecting rod shaft (95), the fourth connecting rod shaft being in the opposite direction to the third connecting rod shaft (94) up extension. Each free end of the third and fourth link shafts (94, 95) is coupled to a pinion (92, 93) which is meshable with the linear gear track (91). In this embodiment, the first shaft (14) of the shaft (13) is further connected to the third connecting rod shaft (94) through the third bevel gear set (74), and the second shaft (15) of the shaft (13) is connected through The fourth bevel gear set (73) is further connected to the fourth link shaft (95).
