Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is one embodiment of the invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Referring to Fig. 1, the present invention includes basal disc 8, two as hoisting and falling the winch 2 of putting basal disc 8, oil cylinder assembly pulley and base 1, the oil cylinder assembly pulley comprises steel rope, fixed pulley 3, movable pulley 4 and plunger tpe compensation of undulation oil cylinder, every winch 2 links by steel rope and basal disc 8 respectively, plunger tpe compensation of undulation oil cylinder is installed on the base 1, also be fixed with outer fix switch 10 and inner side switch 9 on the base 1, plunger tpe compensation of undulation oil cylinder comprises cylinder body 5 and can be at the plunger 6 of cylinder body 5 interior movements, fixed pulley 3 is fixed on the bottom of cylinder body 5, movable pulley 4 is installed on the plunger 6, on cylinder body 5, be connected with energy storage 7 by oil pipe, be provided with the support 11 that can touch outer fix switch 10 and inner side switch 9 at plunger 6.
In the present embodiment, the oil cylinder assembly pulley comprises three movable pulleys 4 that plunger 6 fills previously and four fixed pulleys 3 that fill later, the effective travel of plunger 6 is 1600mm, so the effective compensation stroke of plunger tpe compensation of undulation oil cylinder is 1600mm*6=9600mm, namely positive and negative 4.8 meters.
300mm and 1300mm place at plunger 6 strokes, be provided with respectively inner side switch 9 and outer fix switch 10 on the base 1, winch 2 is by locked when the plunger 6 of plunger tpe compensation of undulation oil cylinder moves in stroke 300mm and 1300mm scope, the stroke of compensation is 1000mm*6=6000mm, be positive and negative 3 meters and be the scope of compensation of undulation, be called passive compensation range, can carry out normal permanent tension compensating at this scope inner plunger formula compensation of undulation oil cylinder, this moment is without any need for power, do not consume any energy, do not produce any heat.
In the time of beyond plunger 6 moves to 300mm and 1300mm, support 11 must touch and be arranged on inner side switch 9 and the outer fix switch 10 that stroke is 300mm and 1300mm place, and inner side switch 9 and outer fix switch 10 are as drift-compensated starting switch.
When ship since drift about out basal disc 8 directly over the time, the distance of ship and basal disc 8 is elongated; Or because of the reason of morning and evening tides sea level rise, the distance of ship and basal disc 8 is also elongated, this moment, plunger 6 range of movement of plunger tpe compensation of undulation oil cylinder departed from 300mm to 1300mm, plunger 6 is to cylinder body 5 interior movements, thereby shake-up inner side switch 9, inner side switch 9 sends signal, so that steel rope is emitted in winch 2 work, plunger 6 range of movement of plunger tpe compensation of undulation oil cylinder is got back in the 300mm to 1300mm.
Otherwise, when ship since the drift get back to basal disc 8 directly over the time, the distance of ship and basal disc 8 shortens; Or descend because of the reason sea level of morning and evening tides, the distance of ship and basal disc 8 also shortens, the range of movement of compensating cylinder plunger 6 also departs from 300mm to 1300mm at this moment, plunger 6 is to cylinder body 5 outer movements, thereby shake-up outer fix switch 10, outer fix switch 10 sends signal, so that steel rope is tightened up in winch 2 work, plunger 6 range of movement of plunger tpe compensation of undulation oil cylinder is got back in the 300mm to 1300mm.
More than be catabiotic in two kinds of situations, but this is the minority time after all, and claims that this kind situation is the Active Compensation scope.
Arrange positive 3 meters to positive 4.8 meters and negative 3 meters to negative 4.8 meters for time the Active Compensation scope, in fact also the range extension of passive compensation to positive and negative 4.8 meters scope.When Active Compensation and positive and negative 4.8 meters passive compensation stack, the scope of compensation is actual can to reach positive and negative 6 meters.Because when Active Compensation, because wave moved a period of time, wave rise and fall this moment speed drops to below the 1.2M/S because V=1.7Cos ω t, so when t=0 V=1.7M/S; V=1.2M/S when t=π/4 ω, even calculate with 1.2M/S later on, because winch 2 has the speed of 0.5M/S cancelling out each other, so the maximum speed of steel rope is 1.2M/S-0.5M/S=0.7M/S, therefore the distance that Active Compensation and passive compensation can compensate altogether in the Active Compensation scope of 1.8M is 1.8M* (1.2M/S)/(0.7M/S)=3.0856M, add 3 meters of passive compensation, therefore approximately can accomplish 6 meters of monolateral compensation, say that the scope that compensates is actual and can reach positive and negative 6 meters.
More than show and described groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
