Description
Technical field
The present invention is applicable to ocean prospecting device, puts and wave compensation system for a kind of the falling of 1500m-3000m marine site prospecting apparatus for work in particular for the depth of water.
Background technology
At present, the used wave compensation system of marine operation divides by the power supply and mainly contains two kinds of passive compensation and Active Compensation.The compensation power resources of passive-type wave compensation system when the ship heave, rely on the hoisting force of wave and the gravity of ship self to compress and discharge the pressurized air in the energy storage, thereby realize heave compensation in the heave of ship.The wave compensation system of the type is consumption of power hardly, therefore uses more extensive.But its disadvantage is exactly the compensation performance instability, and it is bigger to lag behind.The energy of the engine of the compensation work dependence charging system of active wave compensation system itself comes work, like Hydraulic Pump.The type charging system can adopt controlled reset, and antijamming capability is strong, and comformability is good, and compensation precision is high, and compensation performance is stable, but the power that consumes is bigger, only is suitable for the miniwatt occasion.
Ocean prospecting device is a kind of more special marine operation equipment; Equally, rely on passive compensation to satisfy not the power needs merely, and it is excessive to rely on the Active Compensation energy resource consumption fully; In the today of pursuing energy savings, hope has a kind of science more, reasonable compensation system to come out.
Summary of the invention

The specific embodiment
The wave compensation system of device is reconnoitred in a kind of ocean; Two outlets of main pump 3 link to each other with the import of the first selector valve group 4 and the second selector valve group 5 respectively; The outlet of the first selector valve group 4 links to each other 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 links to each other 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 links to each other with the oil-filled mouth of compensating cylinder 13, the outlet of hydraulic control one-way valve 18; The outlet of compensating cylinder 13 links to each other 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 links to each other 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 the 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.
Said compensating cylinder 13 mainly adds 6 multiplying power assembly pulleys by Φ 280mm plunger cylinder and forms, oil cylinder stroke 1600mm, promptly ± 800mm.
Said compensating cylinder 13 hydraulic fluid port security settings pressure 25Mpa, the pressure size is regulated by by pass valve 17.
At said compensating cylinder 13 strokes ± 0.5m upper limit position switch 14 and lower position switch 15 are set.
The steel rope of winch 8 of hoisting is walked around the assembly pulley of compensating cylinder 13 earlier; Then with reconnoitre device 16 and be connected, the up-down of reconnoitring device is by selector valve group 4 and 5 controls, the selector valve group is opened; Main pump 3 is hydraulic wireline winch 8 motor fuel feeding; Drive hydraulic wireline winch 8 and rotate, this system adopts closed circuit, so washout valve group 6 is used for washing away the impurity in the oil circuit.
Under the low sea conditions, compensation of undulation is with the motorless passive fast master that is compensated for as, and this moment, winch was 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 are formed; 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 sea have ± during the billow of 3m; The fluctuation up and down of hull should ± below the 3m; Remain on certain scope in order to ensure the winch cable tensile force, flexible through compensation of undulation oil cylinder 13 and bonded assembly energy storage group 12 control oil cylinders thereof, loosen cooresponding steel rope thereby tighten up; Promptly give the compensation of hydraulic wireline winch 8 steel rope certain force of strain, compensation tension force 20kN～50kN through compensating cylinder 13 and energy storage group 12.Compensating cylinder 13 is oil-filled through auxilliary pump 21, compensating cylinder 13 hydraulic fluid port security settings pressure 25Mpa, and the pressure size is regulated by by pass valve 17.
To put be to drive through winch 8 rotatings in the lifting and falling of prospecting device 16 in the passive compensation; Whole hydraulic efficiency pressure system designs for enclosed, and when installing 16 behind the seabed, winch stops; Because hull can fluctuate with wave; Steel rope is caused unexpected tensioning, influence prospecting work, therefore need compensate equipment.
Compensating cylinder 13 is a plunger tpe, and oil cylinder is installed on the fixed support of ship, and when hull fluctuateed up and down with wave, compensating cylinder 13 plungers were flexible up and down, regulate rope capacity, and prospecting equipment is carried out bit shift compensation, and be passive compensation this moment.(during the steel rope pine; The compensating cylinder plunger up stretches out under the oil pressure effect, and the compensating cylinder oil pressure configures according to depth of water computing value, during the steel rope tensioning; Compensating cylinder pressure increases; Plunger puts in downwards under pull of steel wire, and the fluid in the oil cylinder gets into energy storage 12, when pressure reaches setting value, stops.)
Compensation when Active Compensation is primarily aimed at the ultra operating mode of the wave drift compensation of reconnoitring device 16 and severe sea condition is winch power Active Compensation.Being provided with during drift compensation mainly is to overcoming boats and ships with long variation of stream drift back rope.Rope is long to be changed greatly to following three kinds of reasons are arranged: 1. hull dynamic positioning error drift causes rope length to change; 2. the rope that causes of fluctuation tide is long changes; 3. the 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 all the time and is awaited orders; 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 plunger cross ± during the stroke of 500mm, touch corresponding travel switch; The signal that this switch sends is through the logic control of electric controller; Operate the working connection of corresponding winch 8, make oil pump 3 output oil stream drive winches and receive rope or put rope and change so that the compensation rope is long, impel the range of operation of compensating cylinder plunger to return to ± normal range of 0.5m in.
