Abstract
The invention discloses a floating wave energy device. The corresponding stable part on an energy converter is connected with a motion limiter; wherein, the motion limiter is a damping plate arranged under the energy converter; the damping plate is connected with the energy converter by a bracket; furthermore, a flowing space is formed between the damping plate and the energy converter. In the invention, the damping plate is adopted to restrict the corresponding stable part on the energy converter, therefore, the stability effect is good and the stability effect is not affected by tidal level.
Description
Technical field
The present invention relates to a kind of floating type waving energy device.
Background technique
In the design of floating type waving energy device, relatively stable parts (as rotating shaft in the wave energy apparatus or housing) on the enegrgy converter are kept relative stability, fluctuating at wave, in the flow process, wave action is on enegrgy converter, finish transformation of energy, for simplicity, the parts that the relatively stable parts of enegrgy converter played effect of contraction are called the limit movement body, the stability of this limit movement body plays crucial effects to the conversion efficiency of enegrgy converter, mode by mooring between the relatively stable parts of existing limit movement body such as anchor chain and enegrgy converter is connected, but utilize this method to be difficult to obtain gratifying effect: anchor chain generally is in relaxed state, is difficult to provide the artificer needed constraint; Anchor chain has also limited the motion of Vertical direction in the motion of limit levels direction; When tidal level changed, bigger variation also can take place in the size of the restraining force of anchor chain, made the stablizing effect of anchor chain undesirable, and then had influence on its energy conversion efficiency.
Summary of the invention
The object of the present invention is to provide the floating type waving energy device that a kind of stablizing effect is better, energy conversion efficiency is higher.
The present invention is achieved through the following technical solutions:
Floating type waving energy device, its limit movement body are the damping plate of being located at enegrgy converter below, and this damping plate is connected with relatively stable parts on the enegrgy converter by support, and forms the flowing space between damping plate and enegrgy converter.
The fluid motion rule is more away from the water surface in the wave, fluid motion speed is more little, the present invention utilizes in the wave liquid speed along the variation characteristics of vertical distribution, certain distance is provided with damping plate under the water surface, because the speed that this position water flows is very little, the moving resistance of damping plate is very big, substantially can keep stable, wave is in fluctuating or flow process, water (being the enegrgy converter position) above support produces bigger moving, below (being place, limit movement body position) almost can regard static as; In the wave energy apparatus of the present invention, damping plate can play effect of contraction to enegrgy converter at any time, and when tidal level changed, in the wave energy apparatus of the present invention, the stablizing effect of limit movement body can not be affected yet, and stablizing effect is good,
Further structure of the present invention is:
Described damping plate comprise at least level board, erect plate one of them.When wave moved up and down, level board can play on this direction and hinder and stabilization, and the energy when wave moved up and down is changed; When wave flowed in the horizontal direction, erect plate can play inhibition in the horizontal direction, and the energy during with the wave horizontal motion is changed.
Described damping plate comprises level board and is located at erect plate on this level board, and further, erect plate can be at least two, and these at least two erect plates become the angle of inclination.At least two erect plates are in non-parallel state, promptly these two erect plates can be simultaneously produce inhibition to all around both direction of substantially horizontal, like this, three damping plates can three directions produce inhibition in top to bottom, left and right, front and rear, promptly enegrgy converter is carried out the three-dimensional stability effect, stablizing effect is good; Further optimize structure and be: described erect plate is two, and it is cross that these two erect plates vertically make its horizontal projection mutually.

Embodiment
Embodiment one
As shown in Figure 1, floating type waving energy device, relatively stable parts 1 on the enegrgy converter are connected with the limit movement body, wherein, the limit movement body is to be located at the damping plate (being level board 3) that enegrgy converter 1 below is the level of state, this damping plate is connected with relatively stable parts on the enegrgy converter 1 by support 2, and between damping plate and enegrgy converter 1 the formation flowing space 5.
In the present embodiment, the damping plate of substantially horizontal can play effect of contraction in the motion of Vertical direction to the relatively stable parts on the enegrgy converter 1, when tidal level 6 changes, the stablizing effect of level board 3 can not be affected yet, stablizing effect is good, and enegrgy converter 1 can be converted to power absorption with moving up and down of wave.
Embodiment two
As shown in Figure 2, present embodiment and embodiment's one difference is, described damping plate is an erect plate 4, this erect plate 4 can play the effect of contraction of substantially horizontal to the relatively stable parts on the enegrgy converter 1, when the wave horizontal motion, enegrgy converter 1 can transform absorption to the energy of its horizontal motion.
Embodiment three
As shown in Figure 3, Figure 4, damping plate comprises level board 3 and is located at two mutually perpendicular erect plates 4 on this level board 3 that the horizontal projection of these two erect plates 4 is a cross.The damping plate of present embodiment can three directions play effect of contraction to the relatively stable parts on the enegrgy converter 1 in top to bottom, left and right, front and rear simultaneously, and stablizing effect is good, and is simple in structure.
