Because stormy waves on sea is larger, in the face of in the situation of high sea, in order to guarantee the Safety performance of collecting device 100, collecting device 100 need to be packed up, to hide stormy waves.This collecting device 100 also comprises a link press span 130, lifting device 122 and kickboard platform 124.This kickboard platform 124 is connected with frame 120 by the first above-mentioned guide rail, and lifting device 122 is connected with kickboard platform 124, for driving this kickboard platform 124 to move up and down along the first guide rail; This kickboard 110 is fixed on one end of link press span 130, and other one end and the kickboard platform 124 of link press span 130 are hinged.
Specifically, this lifting device 122 comprises a winch, and this winch is fixed on the top of frame 120, is connected with kickboard platform 124 by rope 126.In the time that wave is too large, lifting device 122 pulls kickboard platform 124 and sliding sleeve 123 to rise by rope 126, and then kickboard 110 moves up thereupon, can adjust according to the size of wave the height of kickboard 110, very simple, convenient.
Refer to Fig. 2 a to Fig. 2 c, for abundant absorption wave energy, utilize to greatest extent unrestrained energy, shape and structure to kickboard 110 design.Below for structure and working principle to this kickboard 110 are described:
The cross section of this kickboard 110 is trapezium structure, and its number is determined 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.Opening is designed to trumpet-shaped this structure, makes can absorb and assemble more water in the time that wave strikes buoyancy device, after wave process, can discharge more water.
In the present embodiment, this kickboard 110 comprises the first kickboard 112 arranged side by side and the second kickboard 113.The centre of this first kickboard 112 is set to the first receiving cavity 1121, on this first receiving cavity 1121 with one facing to the first opening 1122 of wave direction of advance head-on.This first receiving cavity 1121 is to be horn-like that opening successively increases, and along with wave enters the first receiving cavity 1121 by the 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 the second receiving cavity 1131, on this second receiving cavity 1131 with one facing to the second opening 1132 of wave direction of advance head-on.This second receiving cavity 1131 is to be horn-like that opening successively increases, and along with wave enters the second receiving cavity 1131 by the second opening 1132 places, its bore narrows gradually, and wave speed increases, and potential energy increases.
This water turbine comprises the first water turbine 114 and the second water turbine 115.This first water turbine 114 is arranged on the bottom of above-mentioned the 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 arranged on the bottom of above-mentioned the 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.
As shown in Figure 2 a and 2 b, the first water turbine 1141 or the second water turbine 1142 are connected respectively to an air pump 600, this air pump connects and is connected with gas storage tanks 500 by a first-class physical efficiency transducer 400, this wave can convert water turbine after hydraulic energy to, convert first-class physical efficiency dress parallel operation 400 to air pressure, storage is as stored in gas storage tanks 500.
The working principle of this kickboard 110 can be expressed as follows:
As shown in Fig. 2 a to Fig. 2 c, when a wave runs into after kickboard 110 of the present invention, because the weight of kickboard 110 of the present invention own is less, therefore it can floating and rising.Its bottom kickboard is used for collecting wave or has been immersed in the water, or is injecting the first receiving cavity by the water in wave by the first opening or the second opening or the second receiving cavity is filled.After wave is through the first kickboard and the second kickboard, water level can sharply decline, in this stage, the additional weight of the water holding in the first receiving cavity or the second receiving cavity will produce a significant gravity (centrifugal force), and this gravity can pull kickboard device downwards constantly.
In addition, in wave, clash into the energy of kickboard along impulse force direction and be broken down into two rectangular vectorial forces each other: power and a horizontal force along direction vertically rising.On a position between a side and the track bottom (being close in fixed element) of the circular trace of kickboard, two vectorial forces can form a climbing power that kickboard device is promoted towards a side, again water are filled into and in cavity, increase the potential energy of assembling simultaneously.
After wave warp, this extra potential energy will discharge.Produce impact force Wave energy is converted to generated energy by kickboard impulse force of the present invention, can generate electricity.
