Embodiment one
Embodiments of the invention one provide a kind of wave energy propelling unit, comprising:
Energy converter, it has the plane of symmetry, and has the cross sectional shape of airfoil structure perpendicular to the direction of this plane of symmetry on the edge; Wherein, described energy converter has respectively symmetrical upper surface and lower surface in the both sides of the described plane of symmetry;
Many group air deflectors, wherein, every group of air deflector comprises a pair of wing fence structure, this a pair of wing fence structure is separately positioned on described upper surface and the described lower surface of described energy converter.
With reference to Fig. 1, a kind of wave energy propelling unit comprises energy converter 1 and many group air deflectors 2, energy converter 1 has the plane of symmetry 101, and energy converter 1 has with this plane of symmetry 101 laterally zygomorphic structures, and forms upper surface and lower surface take this plane of symmetry as benchmark.On the direction perpendicular to this plane of symmetry 101, the cross sectional shape of energy converter is airfoil structure.
The below describes energy converter produces the navigation thrust of the marine communication means such as boats and ships under the effect of wave energy process:
With reference to Fig. 1, a kind of wave energy propelling unit is immersed in the water in use.Wave originally is up-and-down movement, but after the boats and ships that a kind of wave energy propelling unit is installed started, it had speed of advance, and wave will be obliquely with respect to ship or oblique current downflow, namely have obliquely with respect to gear or oblique under kinematic velocity.With reference to Fig. 1, for example move with respect to energy converter and water velocity when being V when current, under this flow action, can form conversion power under oblique, i.e. lift L at energy converter 1.Lift L can be decomposed into horizontal component of force L1 and vertical component L2, and horizontal component of force L1 always points to the working direction of boats and ships forward, provides power to ship's navigation.With reference to Fig. 1, when the route speed of boats and ships was higher, the lift that energy converter produces was larger, and the energy conversion efficiency of a kind of wave energy propelling unit of the present invention just can be higher.For example, when the route speed of boats and ships is waves up and down during 2.5-8 times of flowing velocity, energy conversion efficiency will be higher.More preferably, when the angle between the plane of symmetry of water velocity V and aerofoil profile is 7-20 °, and boats and ships are when up and down the 2.5-8 of flowing velocity doubly navigates by water with wave, and energy conversion efficiency will reach a high value, is more than 10%, through verification experimental verification, can reach 40%.So based on this imagination, a kind of wave energy propelling unit of the present invention also can increase auxiliary power unit, such as motor etc., so that boats and ships can comparatively fast enter the high speed operational configuration from quiescence.And when shipping high speed navigates by water, can close auxiliary power unit, enable energy converter and air deflector, thereby realize the effective utilization to wave energy.
In embodiment one, a kind of wave energy propelling unit further comprises many group air deflectors 2.Because wave has non-directional and the unequal characteristics of speed, if do not guided, then can produce cancel out each other or with the lift of navigation opposite direction.Air deflector of the present invention then can be arranged on the upper and lower surface of energy converter so that the wave that flows through is carried out water conservancy diversion and rectification, thereby can suppress the mobile interference between the current of friction speed in the adjacent water, the current in the guiding adjacent water achieve as much as possible co-flow.Further, can also suppress the stall phenomenon that energy converter might produce.Stall is after airfoil structure and air-flow or current angle (angle of attack) increase to certain degree (critical angle of attack), airfoil structure upper surface burbling, the phenomenon that causes lift to reduce.Air deflector is the flow direction of bootable water then, more effective lift is produced, thereby effectively avoid the stall phenomenon.In air deflector of the present invention, every group of air deflector comprises a pair of wing fence structure, with reference to Fig. 1, two wing fence structures of every centering are separately positioned on the upper and lower surface of the airfoil structure of energy converter, and wing fence erects setting, have certain altitude in the direction perpendicular to the plane of symmetry, be used for current are played guide functions.Thinner thickness can reduce the resistance to wave simultaneously, can alleviate the weight of hull simultaneously.
