Description

Wave Eddy Current Conversion Device

technical field

The invention relates to the technical field of renewable energy, in particular to a wave-vortex conversion device.

Background technique

Energy shortage and environmental pollution are huge problems facing the world today. In order to maintain social progress, economic development and environmental protection, countries around the world are constantly exploring and developing various alternative energy sources, clean energy sources, especially renewable energy sources. Renewable energy refers to the continuous regeneration in nature, mainly including solar energy, wind energy, hydro energy, biomass energy, geothermal energy and ocean energy. It is a sustainable, inexhaustible and inexhaustible resource that is harmless to the environment and widely distributed.

At present, the kinetic energy of fluid collected in the world is divided into flow energy (current flow, tidal potential energy or tidal flow) and wave energy (oscillation, swing, buoyancy). The force of the fluid acts on the blades. There is a certain angle between the blade and the rotating shaft, and a component force is generated to make the shaft rotate and drive the generator to generate electricity. Its conversion efficiency is equal to the kinetic energy of the action minus the component of the complementary loss of the blade angle, that is to say, it is impossible to reach 100%. In addition, the conversion efficiency is related to the angle of the blade and the flow rate, and the flow rate changes at any time. The expected value of randomly adjusting the blade angle to increase the efficiency is 80-95%, but what can actually be done now is far from this index. Therefore, tidal energy and ocean current energy are now in the exploration and research stage of utilization. The use of tidal energy is to store seawater in the reservoir at high tide, release it at low tide, and use the difference between high and low tide levels to drive the turbine to rotate. Due to the process of storing water, the flow of seawater can be controlled, the loss of energy can be reduced, and the conversion efficiency can reach more than 85%. Therefore, tidal energy has entered a practical stage. 2. Collection of wave energy. Wave energy is the largest kinetic energy in the ocean. Due to the mixed direction of natural wave power, it is changing all the time. It is the most difficult form of kinetic energy to collect. To this end, people try to use the oscillation, sway and buoyancy of objects directly under the action of waves, or use changes in wave pressure, or use waves to climb along the shore to convert into potential energy, and other methods to convert them into rotating mechanical energy. The actual conversion efficiency is around 15-30% and is not stable. Therefore, wave energy is now in the experimental research stage.

In addition, the current technology of collecting ocean currents can only collect flow energy, and the technology of collecting wave energy can only collect kinetic energy such as upper and lower, front and rear, and its specific technology wastes other energy resources that exist simultaneously in the same area.

At present, the hydropower directly acts on the impeller to drive the generator to generate electricity. Solving the instability of the impulse direction of fluids such as ocean currents, waves, and wind is currently the main cost of collecting natural fluid energy. In recent years, with the development of science and technology, a large number of wave energy absorption devices have appeared, and many of them have been used for power generation. "Today, the oscillating water column (OWC) model has been widely used in wave energy conversion devices. But the device has a disadvantage that the wave energy conversion efficiency is relatively low. According to relevant introductions, for decades, the United States, Britain, Japan, Norway, Other countries are developing and building wave energy power stations. Generally, the vertical undulating motion from wave crest to wave valley is used to drive hydraulic or gas turbines; The surge is concentrated in the waterway using methods such as water level difference and pressure difference, but so far no method has been widely used and promoted.”

At this stage, countries in the world are still unable to form large-scale commercial development of wave energy development. All methods can be simply summarized into three steps, namely, one is to convert wave energy into rotating mechanical energy, the other is to convert mechanical energy into electrical energy, and the third is to convert wave energy into electrical energy. Unstable electrical energy is processed into stable electricity and sent to the grid. At present, the second and third parts are relatively mature, and the main problems

The problem is in the first step, that is, how to effectively convert wave energy into rotational mechanical energy.

Detailed ways

The wave vortex conversion device includes an inner cylindrical body 1, a top cover 6, and a bottom cover 5. The inner cylindrical body 1 is provided with a fluid infusion layer 2, an interval layer 3 and a fluid discharge layer 4. The fluid infusion layer 2 is located on the interval layer 3, the fluid discharge layer 4 is located under the interval layer 3, and the fluid infusion layer 2 There are sixteen water inlet grooves 7 cut into the inner barrel body 1, and the water inlet of the water inlet groove 7 is provided with a water inlet groove check door 8. The fluid discharge layer 4 is also arranged with sixteen water inlet grooves cut into the inner barrel body 1. The water outlet groove 9 is provided with a water outlet groove check door 10 at the water outlet of the water outlet groove 9 . The water inlet groove 7 cut into the inner drum body and the water outlet groove 9 cut into the inner drum body are tangentially opposite. The flowing and fluctuating water of the fluid is poured into the tangent line acting on the water column in the inner barrel body from the water inlet, and converted into a whirlpool rotation to form a wave eddy current conversion device.

Working principle: The pressure of waves naturally distributed around the conversion device changes at any time, and the water level inside the conversion device is relatively stable. The water inlet tank changes the flow direction of the water, and its non-return door prevents drainage. When the external water pressure of the water inlet tank in any direction is higher than the internal water pressure, the external water will push the corresponding water inlet tank non-reverse door and pour inward. The water acts on the tangent of the water column in the inner barrel, the direction of rotation is the same, a vortex is formed, and the kinetic energy of the vortex increases. The non-return door of the water outlet prevents water from entering. When the internal water pressure of the water outlet in any direction is higher than the external water pressure, the corresponding non-return door of the water outlet will be pushed open, and the water will be discharged to the outside to reduce the pressure, so as to maintain the internal and external pressure of the water inlet. Difference. The water is fed from the inlet groove at the position of the wave crest, and drained by the drainage groove at the position of the wave trough.

The vortex energy extraction method converted by the device: insert the shaft with the blade vertically into the vortex fluid, and the torsional force of the vortex acts vertically on the rotation of the blade, driving the shaft to rotate. The rotating shaft is connected to a generator, and electricity is available.

In addition, the blades are at a certain angle to gravity, and gravitational potential energy can also be extracted.
