Description

Seawater wave/current comprehensive utilization generator set

technical field

The sea wave/current comprehensive utilization generator set described in the present invention relates to a wave and tidal power generation device, specifically a generator set that simultaneously utilizes sea waves and currents to generate electricity.

Background technique

As the development trend of new energy, wave power generation is being developed by all countries. The principle of wave power generation is as follows:

1. Basic principles:

According to the principle of electromagnetic induction, when the magnetic pole with a certain magnetic induction intensity moves to cut the magnetic force line relative to the coil, the induced electromotive force and current will be generated in the coil.

Induced electromotive force calculation formula:

E＝-BLVsinΦ(V)

in:

B: Magnetic induction (Wb/m^2);

L: coil length (m);

V: Coil cutting magnetic induction line moving speed (m/s);

Φ: the angle between v or L and the magnetic field line;

Coil cutting magnetic induction line movement v and coil L can not be parallel to the magnetic induction line, but can not be perpendicular to the magnetic induction line;

L: effective length (m);

When Φ=90°, E=-BLV(V)

2. Seawater movement and energy conversion:

Generally, there are two forms of motion during seawater motion: surge and seawater flow:

1. The surge causes objects floating on the sea level to move up and down;

2. The flow of sea water will cause plane motion (movement) of objects floating on the sea level;

At the same time, due to the gravitational effect of the moon and the earth, seawater has tidal flow.

The seawater wave/current energy power generation device is actually a device that converts the kinetic energy and potential energy of the wave/water flow into the electric energy of the generator. The composition of the wave/current energy power generation device is generally divided into three parts:

The first part is the collection part of wave/water flow energy, which converts wave/water flow energy into usable mechanical energy through mechanical system, such as water level energy or medium pressure energy;

The second part is the motion conversion mechanism, which converts the energy obtained in the first part into mechanical energy suitable for the movement of the generator structure;

The third part is the power generation device, which converts mechanical energy into electrical energy through a generator.

3. The main principle of the current seawater power generation device

Looking at the current wave energy power generation devices developed at home and abroad, when parameters such as magnetic induction intensity B, coil length L, and moving speed V of the magnetic pole relative to the coil are determined, ordinary seawater power generation devices set the relative movement method of the magnetic pole and the induction coil. Generally, the following two power generation principles are adopted:

1. The magnetic pole and the coil move relatively to cut the magnetic field line to generate electricity (as shown in Figure 4)

When the tidal flow of seawater pushes the magnetic pole to move up and down relative to the coil, the angle between the magnetic line of force and the coil is Φ=90゜, E=-BLV(V), and the efficiency of generating electric energy by seawater tidal flow is the highest;

When the waves of seawater push the magnetic pole to rotate relative to the coil, the angle between the magnetic line of force and the coil is Φ=0゜, and no electric energy is generated; the seawater flow energy cannot be effectively used to generate electricity;

For example, the buoy type permanent magnet linear wave energy generation device has been developed internationally, and the "Sea Snake" wave energy generation device developed by Pelamis Wave Energy Company.

2. The relative rotation of the magnetic pole and the coil cuts the magnetic force line to generate electricity (as shown in Figure 5)

When sea waves push the magnetic pole to rotate relative to the coil, the angle between the magnetic line of force and the coil is Φ=90゜, E=-BLV(V), and the use of surge to generate electric energy is the most efficient;

When the tidal flow of seawater pushes the magnetic pole to move up and down relative to the coil, the angle between the magnetic line of force and the coil is Φ=0゜, and no electric energy is generated;

For example, an energy company named "ATARGIS" headquartered in Colorado, USA has developed a device that uses similar windmill blades for energy conversion. The waves push the two blades to rotate around the central axis and drive the power generation connected to it machine to generate electricity.

Above-mentioned two kinds of ways all can only utilize a kind of mode of sea wave to generate electricity independently, and can not fully and effectively comprehensively utilize the two kinds of forms of sea wave to still sleep the energy and carry out power generation.

In view of the problems in the prior art mentioned above, it is very necessary to study and design a new type of seawater wave/current comprehensive utilization generating set, so as to overcome the problems in the prior art.

Contents of the invention

In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to study and design a novel seawater wave/current comprehensive utilization generating set.

The key point of the present invention is to wind the copper enameled wire and the axis of the coil winding frame at 45° to form an electromagnetic induction coil, and the size and number of turns of the coil need to be calculated according to specific conditions. Put the wound 45-degree winding magnetic induction coil on the outer surface of the fixed column in a coaxial direction with the axis of the fixed column and fix it. The coil position should be a certain height above the sea level. The permanent magnet magnetic poles are arranged on the inner surface of the magnetic sleeve, and the magnetic sleeve is set on the outside of the 45-degree winding magnetic induction coil.

A magnetic sleeve with magnetic poles and a fixed column with a 45-degree winding magnetic induction coil constitute a new type of seawater wave current generator set. The generating set can be placed in the offshore tidal position. When tidal movement forms a sea current, the blades are pushed to drive the cylinder to rotate relative to the column, the magnetic poles move relative to the coil to generate cutting magnetic force lines, and the induced electromotive force output is generated in the fixed coil; when the wave fluctuations push the cylinder to move up and down, the magnetic poles also generate cutting relative to the coil The magnetic force line moves, and the induced electromotive force output is generated in the fixed coil. The upper end of the column is equipped with an elastic limit device to prevent the collision between the fixed part of the generator set and the fixed cable of the column when the moving distance of the magnetic pole exceeds the upper limit of the induction coil when the wave height is too large.

1. In the present invention, the copper enameled wire and the coil winding frame axis are wound at 45° to form a 45° winding magnetic induction coil, which ensures that the magnetic pole can cut the coil when it rotates around the coil and moves up and down the coil under the action of sea waves Generate induced electromotive force output;

2. The present invention utilizes ocean waves and tidal currents to realize the power generation function, and is suitable for offshore islands, aquaculture rafts, navigation mark equipment, etc.

There are currently two ways to supply electricity to offshore islands:

1) The use of submarine cables to transmit electric energy is suitable for larger islands or contiguous islands, and the construction and maintenance costs are high, so it is not suitable for smaller islands;

2) Self-built power plants: equipment investment is large, and air pollution is unavoidable; generally not suitable for islands;

At present, the electricity used for farming rafts and buoy equipment is mainly powered by batteries + solar power generation. The batteries need regular maintenance, and solar power generation is greatly disturbed by weather factors.

The new seawater wave/current comprehensive utilization generator set for power generation fully utilizes seawater energy, can realize all-weather power generation, eliminate air pollution, and ensure the stability and reliability of power consumption. And other advantages, its mass market will produce positive social benefits and significant economic benefits.
