Abstract

A hydrokinetic energy generator generating electricity from a natural water flow. A water-surface platform has an independent vertical-movement platform, and is mounted at a location having an abundant water source and a strong water flow. The generator is connected to a speed-increasing machine, and the speed-increasing machine is connected to a water turbine. A blade surface of the water turbine directly faces the water flow. The vertical-movement platform is controlled to descend, and the water turbine is impacted by the water flow, thereby driving the generator to generate electricity. When the amount of generated electricity meets a design requirement, the vertical-movement platform is stopped, and the height of the vertical-movement platform is adjusted to adapt to a change in a water flow rate, such that the amount of generated electricity is kept at a constant and stable level. According to a second method, a water flow baffle controls the water turbine which is placed in the water; the water flow baffle is controlled to allow a certain surface area of the water turbine blade to be impacted by the water flow; when the amount of electricity generated by the generator meets the design requirement, the water flow baffle is stopped. One or more hydrokinetic energy generators can be disposed along a water flow in series in order to generate a required amount of electricity.

Description

Hydrokinetic generator

Technical field

The invention relates to a hydrokinetic energy generator that uses water flow to generate electricity.

Background technique

Environmental pollution and global warming, governments of all countries are actively advocating the development of clean energy; coal-fired thermal power plants consume large amounts of funds and pollute, solar power and wind power generation are small and unstable. The installed capacity of hydropower stations is limited, and the number of power generation is not enough. .

The principle of a hydroelectric power station is to build a dyke to accumulate enough water to form a large enough water pressure. The water flow is guided and controlled by the waterway and impacts the fixed position of the water wheel propeller to generate kinetic energy to drive the generator to generate electricity; the hydroelectric power station requires large investment and construction The cycle is long, and the number of generators cannot be increased after completion, and the number of power generation is limited.

Summary of the invention

The purpose of the present invention is to provide a hydrokinetic energy generator to solve the current clean energy generators, which have unstable power generation and insufficient power generation.

In order to solve the above problems, the first method of the present invention is to connect the generator to the speed increaser, and connect the water turbine propeller to the lifting platform of the water platform. The water platform is installed in a position with abundant water sources and large currents, and the height of the elevator is adjusted. Responding to changes in water flow, the power generation is always maintained in a stable state; the second method is to control the water turbine paddle installed in the water by the water flow baffle, and operate the water flow baffle to allow the area of the blade to be impacted by the water flow to generate electricity When the generator reaches the power generation required by the design, the water flow baffle stops. There are many rivers that are suitable for installing hydrokinetic energy generators. They can be installed continuously along the water flow, and as much electricity can be produced as much electricity is needed.

The comparison between hydrokinetic energy generators and current generators is as follows:

1 Compared with coal-fired thermal power plants, hydrokinetic energy generators are pollution-free.

2 Compared with solar power generation and wind power generation, hydrodynamic power generators have a stable power generation rate and a high amount of power generation.

3 Compared with hydroelectric power stations, the number of power generation is sufficient, and enough generators can be installed continuously along the current according to needs.

detailed description

Hydrokinetic energy generators include generators, speed-increasing gears, water turbine blades, water flow baffles, and water platforms; water turbine blades are composed of water wheel shafts, hubs, and blades. The larger the length and width of the blade, the greater the water flow During the impact, more water kinetic energy will be obtained; the water platform has an independent lifting platform, which is suitable for installation in a location with abundant water sources and large water flow; the scale of the water platform should be coordinated with other supporting facilities, including the diameter of the water wheel. The size of the water flow depth, the size of the water flow speed, the size of the generator power, and the size of the speed increaser must be fully considered when designing and formulating.

Example 1

The water platform is installed in a location with abundant water sources and large currents. The generator is connected to the output end of the speed increaser, and the input end of the speed increaser is connected to the water wheel shaft. The water turbine blades are directly facing the water flow. It is installed on the lifting platform and has two load-bearing supports. The water wheel shaft is fixed to ensure the balance and stability of the water wheel shaft connected to the speed increaser. The operation controls the elevator to slowly descend. The water wheel blade enters the water. The longer the water wheel blade enters the water, the more water kinetic energy will be obtained. Large, the water turbine blades are forced to drive the water wheel shaft to rotate, the water wheel shaft drives the speed increaser to rotate, and the speed increaser drives the generator to generate electricity. When the output of the generator reaches the design requirement range, the lifting platform stops and the water flow increases. When the lifting platform rises and the water flow decreases, the lifting platform goes down. Adjust the height of the lifting platform to respond to changes in water flow, so that the power generation is always stable.

Example 2

The water platform is suitable for installation in a location with abundant water sources and large water flow. A large wind generator with a power of 2 million watts is equipped with blades with a length of 10 meters and a width of 2 meters. It is installed on the lifting platform of the water platform with the blades facing upright. Regarding the water flow, the operation control lifting platform slowly descends, the blade enters the water, and the impact of the water flow on the blade gradually increases. When the power generation of the wind turbine reaches the design requirement, the lifting platform stops and adjusts the height of the lifting platform to deal with The change in the size of the water flow keeps the power generation in a stable state; the intensity of water kinetic energy is far greater than wind energy, and the continuous stability is better than wind energy; a new invention, no historical data for reference, only as a reference for future hydrokinetic energy generators. The power of the kinetic energy generator, the size of the blades, the number of blades, the depth of water flow, and the speed of water flow need to be tested and tested according to local conditions and matched with reasonable facilities.

Facility example 3

For water platforms with vertical semicircular openings, the water turbine paddles are installed vertically. A load-bearing steel beam is installed between the two points at the bottom of the semicircular opening of the water platform. The middle of the steel beams is equipped with a load-bearing bearing. Fixed at the middle position of the upper part of the semicircular mouth, the upper end of the water wheel shaft is connected to the input end of the speed increaser, and the output end of the speed increaser is connected to the generator. (If the water platform in this state is installed in a position with large water flow, the water turbine paddle All are impacted by the water flow, the water wheel paddle has no direction, the water flow baffle blocks part of the water wheel paddle, the water wheel paddle will have a direction); the water flow baffle blocks the semicircular opening on the inner side of the water platform, half of the water wheel paddle The impact of water flow is the limit of the rotation speed of the water wheel; the water platform is equipped with push-pull, telescopic, and translation devices to control and adjust the arc door outside the semicircular mouth. The arc door is a movable baffle, and the volume of the two arc doors is smaller than Semi-circular mouth and larger than one-fourth of the diameter of the water turbine propeller; after installation, the floating platform is installed in a position with abundant water sources and large water flow, the water turbine blade surface is facing the water flow, the operation control arc door is opened, two arcs The gates each translate to the inside of the semicircular opening. The blades of the water wheel are impacted by the current and gradually become larger and larger. The water wheel propeller drives the speed increaser to rotate, and the speed increaser drives the generator to rotate and generate electricity, and the generator reaches the power generation range required by the design. When the arc door stops, adjust the opening degree of the arc door to deal with changes in the water flow, so that the power generation is always stable.

There are many rivers and oceans that are suitable for installing hydrokinetic energy generators, and the installation can be continuously increased along the current; to build a large-scale water power station, as much electricity is required as much electricity is required, provided that the corresponding installed capacity needs to be invested first; wind turbines It is equivalent to a small horse-drawn cart with insufficient rear force, and the hydrodynamic generator is equivalent to a large horse-drawn cart with sufficient rear force.
