Embodiment

As shown in Figure 1, the device of the utility model Waving piston transducing is the offshore structure body, is made up of the two large divisions: a part is for being used to receive and the elevated reservoir 3 of transducing, a part for place reservoir below and float on the sea adopt the energy system unit.

Described elevated reservoir and the agent structure that makes up across the sea is one, it is highly decided by the design head requirement for height, the stable energy of head of a level altitude is provided to the application of secondary energy, under the effect of wave energy, the seawater supercharging and be injected into the purpose that has just realized transformation of energy in the reservoir that occupy high-order.

Adopting of described reservoir below can comprise one group of piston body of inserting piston cylinder in the sea 4 and including 5 by cell arrangement, and the piston cylinder top is and the pressure inlet 2 of its perforation that pressure inlet 2 heads insert elevated reservoir, and upper end-hole is higher than the reservoir bottom surface.One ball float 1 that floats on the sea level is set on piston cylinder 4 and the pressure inlet 2.In pressure inlet, be provided with backflow one-way valve 7 (the reducing place that is located at pressure inlet is good), on piston body, be provided with into water supercharging one-way valve 8; Connection is established multistage resistance baffle 6 in the bottom of piston body 5.

Length of thread engagement between the piston body that described piston cylinder and its include should be greater than the maximum wave height in putting marine site.

Piston body 5 proportions determine that principle should satisfy: its height peak that revolves in the floating deep water should be greater than the maximum wave height in this marine site from piston cylinder vertex distance h.

Described ball float 1 and rigidly connected two assemblying bodys of piston body 5 right and wrong.Piston cylinder 4 and piston body 5 should satisfy the motion of omnidirectional mechanism, and it is fixed should to satisfy the requirement of spatial mechanism's degrees of freedom through length H and matching gap δ, and the water pressure of piston cylinder is that the effective section by long-pending sum of deep-water resistance baffle 6 effective sections and piston amasss D ² _n/ d ²Determine.

Ball float 1 on the water surface is the carrier of this device, adopt the main body of energy especially, its geometric shape can be the conical funnel type, determine its direction non-selectivity to wave, comprehensive collection wave energy is subjected to the wave energy effect that it is upwards floated---and promptly force piston cylinder 4 to move upward, and produce relative displacements with respect to the ball float 1 relative static piston body that is in deep water 5, this process is called the work done phase of wave energy, also is to adopt the energy process.When wave energy disappears, because the quality of quality of itself and elevated reservoir is subjected to earth attraction to do to sink in order to certain speed, its momentum acts on the relatively-stationary with it piston body 5 fully, water pressure in the piston cylinder is increased, be expressed in the elevated reservoir, absorb ball float 1 momentum and be converted into the potential energy of elevated reservoir, can thereby realized efficiently adopting, and be converted into the stable potential energy of certain altitude, pressure in the piston cylinder 4 is decided by the gross mass of ball float 1, the long-pending ratio of effective section that also is decided by the long-pending resistance baffle 6 with under water of effective section of piston cylinder 4 is because of D ² _SummationThe d of＞＞＞ ²So, judge that piston body 5 relative ball floats 1 are the solid obstacle bodies of a random position orientation.Because the distance on its plane off sea of the proportion of piston body 5 decision is a constant definite value, and because it is in and influenced by wave of the sea can to ignore, so can only relative moving take place along the medial axis of the two when ball float 1 is subjected to wave energy to do the time spent, piston body 5 conditions each other with piston cylinder 4.Adopted this method exactly, guaranteed both under the ocean environment of upheaval, realized relative movement, direction is opposite, and it is vertical that active force keeps, and obtains maximum conversion efficiency.
