Abstract
The invention discloses a stretchy suspension pendulum device capable of capturing wave energy. The device is composed of a suspension support, a hydraulic cylinder, a pendulum piece, a pendulum piece sealing part and a support sealing part. The lower end of the suspension support is in a pendulum-piece shape and is hollow, the pendulum piece is arranged inside the suspension support, the pendulum piece is hollow, the hydraulic cylinder is installed in the pendulum piece, a cylinder barrel of the hydraulic cylinder is welded with the suspension support, a cylinder rod of the hydraulic cylinder is hinged to the inner wall of the pendulum piece, and the pendulum piece sealing part and the support sealing part are arranged between the pendulum piece and the suspension support. The hydraulic cylinder can drive the pendulum piece to conduct axial stretchy motion inside the lower end of the suspension support, therefore, the length of the portion, submerged in the water, of a suspension pendulum is adjusted, the matching between the suspension pendulum capturing efficiency and the wave energy is achieved, and self-existence capability of the suspension pendulum type wave energy utilization device under the extremely severe situation such as the windstorm and the typhoon can be improved.
Description
Technical field
The present invention relates to a kind of suspension pendulum device of catching wave energy, particularly telescopic suspension pendulum device.
Background technique
Hanging the pendulum-type wave energy utilizing apparatus is a kind of typical coastal engineering device, can absorb ocean wave energy, is converted into electric energy or realizes desalination of sea water, has higher wave energy conversion efficiency.Hanging pendulum is the core component in this kind of wave energy utilizing apparatus, by it, in the swing under wave action, realizes catching of Wave energy.Existing suspension pendulum structure is all integral type, can't regulate the matching relationship between capture rate and Wave energy.When Wave energy exceeds the design output power that hangs the pendulum-type wave energy utilizing apparatus, especially under the exceedingly odious conditions such as storm, typhoon, existing integral type suspension pendulum will bear huge wave force, thereby easily cause hanging the destruction of pendulum-type wave energy utilizing apparatus.
Summary of the invention
The object of the present invention is to provide a kind of scalable suspension pendulum device of catching wave energy.
The technical solution adopted for the present invention to solve the technical problems is:
The present invention includes suspension holdfast, oil hydraulic cylinder, pendulum, pendulum Sealing and support Sealing.The suspension holdfast lower end is pendulum shape and hollow, and inside is equipped with pendulum.The pendulum inner hollow, be equipped with oil hydraulic cylinder.Barrel of Hydraulic Cylinders and suspension holdfast weld together, and hydraulic cylinder bar and pendulum inwall are hinged.Pendulum Sealing and support Sealing are installed between pendulum and suspension holdfast.Oil hydraulic cylinder can drive pendulum to do the axial stretching motion in inside, suspension holdfast lower end.
The invention has the beneficial effects as follows:
(1) oil hydraulic cylinder can drive the pendulum axial motion, thereby regulate, hangs the length that pendulum is immersed in the water part.It is more that the suspension pendulum is immersed in the water part, and the Wave energy capture rate is higher; It is fewer that the suspension pendulum is immersed in the water part, and the Wave energy capture rate is higher.When running into the exceedingly odious condition such as storm, typhoon, drive oil hydraulic cylinder to make to hang pendulum and no longer be immersed in water, can make to hang pendulum and avoid bearing huge wave force, thereby improve the ability of certainly depositing that hangs the pendulum-type wave energy utilizing apparatus.
(2) each component structural is simple, is convenient to processing and assembling.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that in the present invention, oil hydraulic cylinder is regulated the schematic diagram of portal swing axle to length.
In figure: 1, suspension holdfast, 2, oil hydraulic cylinder, 3, the pendulum Sealing, 4, pendulum, 5, the support Sealing.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As depicted in figs. 1 and 2, the present invention is comprised of suspension holdfast 1, oil hydraulic cylinder 2, pendulum 4, pendulum Sealing 3 and support Sealing 5.Suspension holdfast 1 lower end is pendulum shape and hollow, and inside is equipped with pendulum 4.Pendulum 4 inner hollow, be equipped with oil hydraulic cylinder 2.Oil hydraulic cylinder 2 cylinder barrels and suspension holdfast 1 weld together, and oil hydraulic cylinder 2 cylinder bars and pendulum 4 inwalls are hinged.Pendulum Sealing 3 and support Sealing 4 are installed between pendulum 4 and suspension holdfast 1.Oil hydraulic cylinder 2 can drive pendulum 4 to do the axial stretching motion in suspension holdfast 1 inside, lower end, hang thereby regulate the length that pendulum is immersed in the water part, realize hanging the coupling between pendulum capture rate and Wave energy, and can improve certainly the deposit ability of pendulum-type wave energy utilizing apparatus under the exceedingly odious conditions such as storm, typhoon that hang.
