Abstract
The invention relates to a method for limiting degree of freedom of a floating wave dissipation and energy absorption dam. The floating wave dissipation and energy absorption dam clings to a sea surface, and energy absorption efficiency is improved. The floating wave dissipation and energy absorption dam transforms wave energy by compressing air through rise and fall of waves. By the aid of the method, two adjacent stages can be buffered by each other, the position of the floating wave dissipation and energy absorption dam can be ensured, and the floating wave dissipation and energy absorption dam can efficiently absorbs energy.
Description
Technical field
The present invention relates to a kind of method of unrestrained energy-absorbing dam degree of freedom of disappearing of floating that limits, making floats the floating on the sea that unrestrained energy-absorbing dam can be stable that disappear.
Background technology
Floating, the influence owing to stormy waves can produce moving freely in the certain limit when disappearing unrestrained energy-absorbing dam layout and sea, this efficient that moves meeting reduction energy-absorbing freely.Traditional method can only be carried out grappling for this situation, but needs high-intensity connection, and cost is very high, and uses and need after several years to change.
Summary of the invention
The present invention relates to a kind of method that limits the unsteady unrestrained energy-absorbing dam degree of freedom that disappears, be used for making the unsteady unrestrained energy-absorbing dam that disappears to be close to the sea, improve energy-absorbing efficient.The unsteady energy-absorbing unrestrained dam that disappears utilizes heaving of the sea compressed air to carry out the wave transformation of energy.The present invention is made up of the fixed pulley that is fixed in the seabed, hawser, floatage body.The unsteady unrestrained energy-absorbing dam that disappears links to each other with floatage body by hawser, and this hawser makes the direction of motion on floatage body and the unsteady unrestrained energy-absorbing dam that disappears opposite by being fixed in the fixed pulley in seabed; Before and after the two neighboring pole energy-absorbing unrestrained dam that disappears that floats link to each other by hawser, this hawser is by two fixed pulleys that are fixed in the seabed, and these two pulleys directly have certain distance, makes hawser become " recessed " font, on the hawser between two fixed pulleys a floatage body is arranged fixedly, be used for this section of tensioning hawser.Floatage body disappears at unsteady energy-absorbing can provide certain accumulation of energy cushioning effect when unrestrained dam falls after rise, improves the disappear energy-absorbing efficient on unrestrained dam of the energy-absorbing that floats.

3. according to claim 1, floatage body is immersed in the water fully, and the buoyancy that produces makes the hawser tensioning, is used for the unsteady unrestrained energy-absorbing dam degree of freedom that disappears of restriction.
4. according to claim 1, the fixed pulley that is fixed in the seabed is used for changing by hawser the direction of power.
5. according to claim 1, hawser is used for the power transmission with the floatage body generation, and connects floatage body and the unrestrained energy-absorbing dam that disappears that floats.
6. according to claim 1, floatage body produces the accumulation of energy effect in the return process, having improved the efficient of the unsteady unrestrained energy-absorbing dam energy-absorbing that disappears.
7. according to claim 1, floating disappears is linked to each other by the hawser that is fixed in the fixed pulley in seabed by two between the unrestrained energy-absorbing dam two neighboring pole, is used for the mutual restraint of liberty degree of front and back stages.
8. according to claim 7, between two fixed pulleys certain distance is arranged, make the hawser that passes through become " recessed " type.
9. according to claim 7, fix a floatage body on the hawser between two pulleys, make the hawser tensioning.
10. according to claim 9, be fixed on two floatage bodies on the hawser between the pulley certain accumulation of energy effect also can be provided, improve the energy-absorbing efficient on the unsteady unrestrained energy-absorbing dam that disappears.
