See also Fig. 2 a to Fig. 2 c, for fully absorb wave can, utilize to greatest extent wave can, the shape and the structure of kickboard 110 designed.Below for the structure and the working principle of this kickboard 110 are described:
The cross section of this kickboard 110 is a trapezium structure, and its number is decided according to practical situation.Kickboard 110 has the opening of inclination, thereby makes its upper limb nearer than its lower edge apart from the above-mentioned wave that heads on.This kickboard 110 comprises a wave flow-guiding surface, and it stretches to above-mentioned head-on wave above this opening.Open design becomes trumpet-shaped this structure, makes when wave strikes the buoyancy device, can absorb and assemble more water, after the wave process, can discharge more water.
In the present embodiment, this kickboard 110 comprises first kickboard 112 arranged side by side and second kickboard 113.The centre of this first kickboard 112 is set to first receiving cavity 1121, has first opening 1122 facing to the wave direction of advance that heads on this first receiving cavity 1121.This first receiving cavity 1121 is to be horn-like that opening increases one by one, and along with wave gets into first receiving cavity 1121 by first opening, 1122 places, its bore narrows gradually, and wave speed increases, and potential energy increases.
The centre of this second kickboard 113 is set to second receiving cavity 1131, has second opening 1132 facing to the wave direction of advance that heads on this second receiving cavity 1131.This second receiving cavity 1131 is to be horn-like that opening increases one by one, and along with wave gets into second receiving cavity 1131 by second opening, 1132 places, its bore narrows gradually, and wave speed increases, and potential energy increases.
This water turbine comprises first water turbine 114 and second water turbine 115.This first water turbine 114 is installed in the bottom of above-mentioned first receiving cavity 1121, the smallest end opening of horn-like opening; This first water turbine 114 is to be made up of water turbine rotation blade wheel 1141 and water turbine stator blade wheel 1142.This second water turbine 115 is installed in the bottom of above-mentioned second receiving cavity 1131, the smallest end opening of horn-like opening; This second water turbine 115 is to be made up of water turbine rotation blade wheel 1151 and water turbine stator blade wheel 1152.
Shown in Fig. 2 a and Fig. 2 b; First water turbine 1141 or second water turbine 1142 are connected respectively to an air pump 600; This air pump connects through a first-class physical efficiency transducer 400 and is connected with gas storage tanks 500; After this wave can convert water turbine to the hydraulic pressure ability, convert first-class physical efficiency dress parallel operation 400 to air pressure, storage is as storing in the gas storage tanks 500.
The working principle of this kickboard 110 can be explained as follows:
Shown in Fig. 2 a to Fig. 2 c, after a wave ran into kickboard 110 of the present invention, because kickboard 110 own weight of the present invention are less, so it can floating and rising.Its bottom kickboard is used for collecting wave or immersed water, perhaps injects first receiving cavity through the water in the wave by first opening or second opening or second receiving cavity is filled.After wave is through first kickboard and second kickboard; Water level can sharply descend; In this stage, the additional weight of the water that holds in first receiving cavity or second receiving cavity will produce a significant gravity (centrifugal force), and this gravity can spur the kickboard device downwards constantly.
In addition, the energy along impulse force direction bump kickboard is broken down into two rectangular each other vectorial forces in the wave: a power and the horizontal force along direction that vertically rises.On a side and a position between the track bottom (being close in fixed element) of the circular trace of kickboard, two vectorial forces can constitute one with the kickboard device towards the moving climbing power of a thruster, again water being filled into simultaneously increases the potential energy of assembling in the cavity.
After the wave warp, this extra potential energy will discharge.Produce impact force and convert Wave energy into generated energy through kickboard impulse force of the present invention, can generate electricity.
In addition; In order to improve the energy absorption capability of kickboard device of the present invention; It is towards the wave flow-guiding surface of the wave that heads on, and first water turbine 114 and second water turbine 115 that are installed in this first receiving cavity 1121 and second receiving cavity 1131 drive water turbine rotation blade wheel 1141,1151 and water turbine stator blade wheel 1142,1152 respectively.First water turbine 1141 or second water turbine 1142 are connected respectively to air pump 600; This air pump 600 connects through a first-class physical efficiency transducer 400 and is connected with gas storage tanks 500; After this wave can convert water turbine to the hydraulic pressure ability; Convert first-class physical efficiency dress parallel operation 400 to air pressure, storage is as storing in the gas storage tanks 500.Generate electricity through extra two water turbine that are arranged in two water tanks, made full use of the energy of wave.
1) more than the depth of water 3-4 rice, flood tide and ebb differs 4 meters, and the 2m that ebbs tide is good with seascarp, and coastal landform can be thought technological adjustment;
