The specific embodiment
The wave compensation system of device is reconnoitred in a kind of ocean, two outlets of main pump 3 are connected with the import of the second selector valve group 5 with the first selector valve group 4 respectively, the outlet of the first selector valve group 4 is connected with the P mouth of washout valve group 6, the hydraulic fluid port of hydraulic wireline winch 8, the outlet of the second selector valve group 5 is connected with the T mouth of washout valve group 6, the import of balance cock 7, and the hydraulic fluid port of the outlet of balance cock 7 and hydraulic wireline winch 8 is connected to form the lifting side of closed circuit; The import of by pass valve 17 is connected with the oil-filled mouth of compensating cylinder 13, the outlet of hydraulic control one-way valve 18, the outlet of compensating cylinder 13 is connected with compression indicator 10 with energy storage 12, nitrogen gas cylinder 11 and inflation ball valve 9, the P mouth of change-over valve 19 is connected with the outlet of check valve 20, the T mouth of change-over valve 19 is connected with fuel tank 1, between main pump 3 and fuel tank 1, complementary pump 21 and fuel tank 1, ball valve 2 is housed; The steel rope of hydraulic wireline winch 8 is walked around the assembly pulley of compensating cylinder 13, and reconnoitres device 16 and is connected.
Described compensating cylinder 13 mainly adds 6 multiplying power assembly pulleys by Φ 280mm plunger cylinder and forms, oil cylinder stroke 1600mm, ± 800mm.
Described compensating cylinder 13 hydraulic fluid port security settings pressure 25Mpa, pressure size is regulated by by pass valve 17.
At described compensating cylinder 13 strokes ± 0.5m, upper limit position switch 14 and lower position switch 15 are set.
The steel rope of hoister winch 8 is first walked around the assembly pulley of compensating cylinder 13, then with reconnoitre device 16 and be connected, reconnoitring the lifting of device is controlled by selector valve group 4 and 5, selector valve group is opened, main pump 3 is hydraulic wireline winch 8 motor fuel feeding, drive hydraulic wireline winch 8 to rotate, this system adopts closed circuit, so washout valve group 6 is used for washing away the impurity in oil circuit.
Under low sea conditions, compensation of undulation is with the motorless quick passive master that is compensated for as, and now winch is to shut down armed state, the dry run position work but hydraulic pressure main pump 3 mediates.Passive compensation of undulation is by compensating cylinder 13, and piston accumulator 12 and nitrogen gas cylinder 11 form; Compensating cylinder 13 mainly adds 6 multiplying power assembly pulleys by Φ 280mm plunger cylinder and forms, and oil cylinder stroke 1600mm is ± 800mm, so compensation range is ± 4800mm.When the billow of have ± 3m of sea, the fluctuation up and down of hull should ± below 3m, in order to ensure winch cable tensile force, remain on certain scope, by the Accumulator arrangements 12 of compensation of undulation oil cylinder 13 and connection thereof, control oil cylinders flexible, thereby tighten up, loosen corresponding steel rope, by compensating cylinder 13 and Accumulator arrangements 12, give hydraulic wireline winch 8 steel ropes certain tension compensating, compensation tension force 20kN～50kN.Compensating cylinder 13 is oil-filled by auxiliary pump 21, compensating cylinder 13 hydraulic fluid port security settings pressure 25Mpa, and pressure size is regulated by by pass valve 17.
In passive compensation, reconnoitre the lifting of device 16 and fall that to put be to drive by winch 8 rotatings, whole hydraulic efficiency pressure system designs for enclosed, when device 16 is behind seabed, winch stops, because hull can fluctuate with wave, steel rope is caused to unexpected tensioning, affect survey, therefore need to compensate equipment.
Compensating cylinder 13 is plunger tpe, and oil cylinder is arranged on the fixed support of ship, and when hull fluctuates up and down with wave, compensating cylinder 13 plungers are flexible up and down, regulate rope capacity, and prospecting equipment is carried out to bit shift compensation, are now passive compensation.(during steel rope pine, compensating cylinder plunger up stretches out under oil pressure effect, compensating cylinder oil pressure sets according to depth of water computing value, during steel wire tensioning, compensating cylinder pressure increases, plunger puts in downwards under the pulling force of steel rope, and the fluid in oil cylinder enters energy storage 12, until pressure stops while reaching setting value.)
The compensation of Active Compensation when reconnoitring the wave drift compensation of device 16 and the super operating mode of severe sea condition is winch power Active Compensation.Arranging during drift compensation is mainly for overcoming boats and ships with long variation of the rear rope of stream drift.Rope is long to be changed greatly to there being following three kinds of reasons: 1. hull dynamic positioning error drift causes rope length to change; 2. long variation of rope that fluctuation tide causes; 3. ocean current water resistance causes steel rope to form radian and long variation of rope of causing.
The work drive motor oil pump group that is set to of drift Active Compensation is opened and is awaited orders all the time, at compensating cylinder 13 strokes ± 0.5m, oil cylinder stroke upper limit position switch 14 and oil cylinder stroke lower position switch 15 are set, when plunger belongs to normal ± 3m compensation of undulation during operation in ± 0.5m, when the stroke of cross ± 500mm of plunger, touch corresponding travel switch, the signal that this switch sends is by the logic control of electric controller, the working connection of operational correspondence winch 8, making oil pump 3 output oil streams drive winch rope closing or put rope changes so that compensation rope is long, impel the range of operation of compensating cylinder plunger to return to ± normal range of 0.5m in.
