Description

Wave vortex conversion device

Technical Field

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

Background

Energy shortage and environmental pollution are great problems facing the world today. In order to maintain social progress, economic development and environmental protection, various countries in the world are constantly exploring and developing various alternative energy sources and clean energy sources, particularly renewable energy sources. Renewable energy refers to the energy which can be continuously regenerated in nature and mainly comprises solar energy, wind energy, water energy, biomass energy, geothermal energy, ocean energy and the like. The method is a resource which is continuously utilized, inexhaustible and inexhaustible, is harmless to the environment and has wide resource distribution.

The current world collects fluid kinetic energy, which is divided into flow energy (flow of ocean current, potential energy of tide or flow of tide) and wave energy (oscillation, swing and buoyancy), and energy collection and conversion modes thereof are as follows: 1. the flow energy is collected by applying force from the fluid to the blades. The blades and the rotating shaft form a certain included angle to generate component force to rotate the shaft and drive the generator to generate electricity. The conversion efficiency is equal to the kinetic energy applied minus the complementary loss component of the blade angle, i.e. it cannot reach 100%. In addition, the conversion efficiency is related to the angle of the blade and the flow rate, the flow rate changes at any time, the expected value of the efficiency increase by randomly adjusting the blade angle is 80-95%, and the index can not be achieved at present. Therefore, tidal current energy and ocean current energy are now under the stage of research and study for their utilization. The utilization of tidal energy is that sea water is stored in a reservoir when the tide rises and is discharged when the tide falls, and the water turbine is driven to rotate by the difference between high and low tide levels. The flow of the seawater can be controlled due to the process of storing water, the loss of energy is reduced, and the conversion efficiency reaches more than 85%. Thus, tidal energy has entered a practical stage. 2. The wave energy is collected, the wave energy is the largest kinetic energy in the ocean, and the natural wave power direction is mixed and is changed all the time, so that the wave energy is the kinetic energy form with the largest collection difficulty. Therefore, people try to convert the object oscillation and swing under the direct action of waves and buoyancy into rotary mechanical energy in various modes, such as by using the change of wave pressure, or by using the potential energy converted by the waves climbing along the shore, and the like. The actual conversion efficiency is about 15-30% and is unstable. Therefore, wave energy is now in the experimental study phase.

In addition, the current technology for collecting ocean current can only collect flow energy, and the technology for collecting wave energy can only collect kinetic energy of up and down, front and back, and the like, and the specific technology wastes other energy resources existing in the same area at the same time.

At present, the mode that fluid power directly acts on an impeller is adopted to drive a generator to generate electricity. The solution to the instability of impulse directions of fluids such as ocean currents, ocean waves and wind is the main cost for collecting natural fluid energy at present. In recent years with the development of scientific technology, a large number of wave energy absorbing devices have emerged, and many of them have been used to generate electricity. "nowadays, the Oscillating Water Column (OWC) model has been widely applied to wave energy conversion devices. One disadvantage of this arrangement is that the efficiency of the wave energy conversion is relatively low. By introduction, for decades, countries such as the united states, the united kingdom, japan, norway, etc. have developed and built wave power plants, which typically use vertical heave motions from wave crest to wave trough to drive water or gas turbines; the leaf machine is pushed by mechanical elements such as a cam and the like through back and forth movement of waves, and other methods such as the method of concentrating surge in a water channel and utilizing water head difference, pressure difference and the like do not exist, but the method is not widely applied and popularized at present.

At present, wave energy development of all countries in the world cannot form large-scale commercial development, and all methods can be simply summarized into three steps, namely, the wave energy is converted into rotational mechanical energy, the mechanical energy is converted into electric energy, and unstable electric energy is processed into stable electricity and is transmitted to a power grid. At present, the second and third parts are mature and there are main questions

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

The inner circle barrel body 1 is provided with a fluid filling layer 2, a spacing layer 3 and a fluid discharging layer 4, the fluid filling layer 2 is positioned on the spacing layer 3, the fluid discharging layer 4 is positioned below the spacing layer 3, the fluid filling layer 2 is provided with sixteen water inlet grooves 7 cut in the inner circle barrel body 1, the water inlet of the water inlet grooves 7 is provided with a water inlet groove check door 8, the fluid discharging layer 4 is also provided with sixteen water outlet grooves 9 cut in the inner circle barrel body 1, and the water outlet of the water outlet grooves 9 is provided with a water outlet groove check door 10. The water inlet groove 7 cut on the inner circular barrel body and the water outlet groove 9 cut on the inner circular barrel body are opposite in tangential direction. The flowing and fluctuating water of the fluid is filled into the tangent line of the water column in the inner drum body from the water inlet groove and is converted into vortex-type rotation, thus forming the wave vortex conversion device.

The working principle is as follows: the pressure of the waves naturally distributed around the conversion means varies at any time, while the water level inside the conversion means is relatively smooth. The flow direction of water is changed in the intake chamber, and its check door stops the drainage, and when the outside water pressure of intake chamber of any direction was higher than inside water pressure, outside water all can push open corresponding intake chamber check door and inwards pour into, and the water effect of pouring is on the tangent line of cask water column including on, and the direction of rotation is unanimous, forms the swirl, and the kinetic energy of swirl increases. When the internal water pressure of the water outlet tank in any direction is higher than the external water pressure, the corresponding water outlet tank check door is pushed open, water is drained outwards, the pressure is reduced, and the internal and external pressure difference of the water inlet tank is maintained. The water is fed from the water inlet groove at the wave crest position, and is discharged from the water discharge groove at the wave trough position, so that the fluid enters and exits from the pressure difference between the crest and the trough generated by the stable water level inside the water tank, and a circulation mechanism is formed.
