The subsurface buoy hydraulic buoyant force driving system comprises a shell, an inner leather bag, an outer leather bag, a hydraulic cylinder and a drive mechanism. The outer leather bag is arranged outside the shell, and the inner leather bag, the hydraulic cylinder and the drive mechanism are all arranged in the shell. The hydraulic cylinder comprises a cylinder body and a piston arranged inside the cylinder body. The inner leather bag is communicated with the cylinder body through a second two-way valve, and the outer leather bag is communicated with the cylinder body through a first two-way valve.

Description
Technical field
The utility model relates to a kind of seabed subsurface buoy observation system, relates in particular to a kind of subsurface buoy floating force driving system.
Background technology
The hydraulic floatage drive system is the core of submarine hydrothermal solution/cold spring systematic observation subsurface buoy, and subsurface buoy crust CF presses the stereomutation of oil to be provided by it, and subsurface buoy is also finished by it in the depthkeeping motion of vertical section.It is the key that can subsurface buoy finish the work, and its performance quality is related to the reliability of monitoring platform.For satisfying the requirement that monitoring platform can carry out depthkeeping control at 2000m, floating force driving system must have big discharge capacity, high flow and the maximum ability that can do work under 25Mpa pressure.Based on above-mentioned requirements, the population parameter of subsurface buoy hydraulic efficiency pressure system is decided to be: discharge capacity 〉=500ml; Flow 〉=25ml/min; Maximum working pressure (MWP) 25Mpa; Overall weight≤7kg.
Usually adopt following several subsurface buoy buoyancy-driven modes in the prior art:
The single stage hydraulic cylinder scheme: use single stage piston formula hydraulic actuating cylinder, by the driven by motor leading screw, from outer leather bag suction oil, the subsurface buoy overall volume changes in the reciprocating motion of the pistons process.The whole hydraulic system structure of this kind scheme is simple, low cost of manufacture.Design plan is suitable for the less Argo buoy of total quality and uses (general 30 kilograms), but for large volume with than the monitoring platform system of heavy amount, this buoyancy-driven scheme is difficult for satisfying the requirement of big discharge capacity; The leading screw stroke is longer, easily unstability; The hydraulic efficiency pressure system discharge capacity is definite value in system design back, and discharge capacity enlarges difficult.For this kind design plan, establish diameter of piston rod D=0.03m, if will reach the discharge capacity of 500ml, then the power of bearing on the piston is 17671N, and piston length is 919.6mm, and hydraulic actuating cylinder weight is 3.036kg.According at present existing leading screw calculation of parameter as can be known, leading screw has been in instability status in this design plan, does not meet design requirement.Simultaneously, this scheme on big discharge capacity and flow also difficulty satisfy this platform requirement, the hydraulic efficiency pressure system overall length is about 1.4m, is unfavorable for the monitoring platform interior layout, so do not adopt this scheme.
The multistage hydraulic cylinder scheme: main hydraulic cylinder under low pressure uses, and can realize the heave movement of subsurface buoy in more shallow scope, because working depth is more shallow, can use bigger hydraulic actuating cylinder internal diameter, finishes the change of monitoring platform large volume.Secondary hydraulic actuating cylinder is also gradable according to the working depth difference, uses less internal diameter, and the small size of subsurface buoy changes when being implemented in deep ocean work.Total system can realize that hydraulic actuating cylinders at different levels can time-sharing work, classification oil extraction, conserve energy; Can realize simultaneously big discharge capacity.But this system's design is complicated, and driving system and power part are many, and cost height and reliability are relatively poor.The max.cap. of hydraulic efficiency pressure system is definite value after system's design is finished simultaneously, and the discharge capacity expansion is difficult to realize.Because use multistage hydraulic cylinder, the overall weight of hydraulic actuating cylinder has reached 2.94kg, according to general driving system estimation, its weight is about 2 times of calculating of hydraulic actuating cylinder weight, and then the hydraulic efficiency pressure system total weight is about 8.82kg, so the hydraulic efficiency pressure system overall weight is bigger.The hydraulic efficiency pressure system overall length of this design plan is about 1.2m simultaneously, is unfavorable for the monitoring platform interior layout.
The high-pressure plunger pump assembled scheme of primary pinion pump and back level: the primary pinion pump is used for the preliminary supercharging of hydraulic oil of internal leather bag, satisfies the operating needs of high-pressure plunger pump, can separate out the air in the hydraulic oil simultaneously, improves the functional reliability of high-pressure plunger pump.Behind the hydraulic oil process primary pinion pump, flow to outer leather bag via high-pressure plunger pump and check valve, change the leather bag volume.By pass valve between primary pinion pump and high-pressure plunger pump is used for the earial drainage of big displacement gear pump.Then by three two three-way electromagnetic valves transpositions, flow through flow regulating valve and by pass valve were got back to interior leather bag when hydraulic oil refluxed from outer leather bag to interior leather bag.Conceptual design can be realized big discharge capacity, and discharge capacity is not subjected to design constraint, can conveniently expand.Native system uses existing pump, valve to build simultaneously, needs self-designed parts few, and it is fast that scheme is finished speed.But this scheme system is complicated, is difficult to the stereomutation that realizes that subsurface buoy is quantitative, and the required element of system is many, poor reliability, and weight is big.Because systematic comparison complexity and weight are bigger than normal, finish comparatively difficulty of quantitative oil extraction.
