Technical field
This utility model belongs to buoyancy regulating device field, is applicable to underwater particularly to the one in this field
The water hydraulic buoyancy regulating system of floating apparatus in the dive the most voluntarily such as people, buoy, bathyscaph, underwater glider.
Background technology
Hydraulic-driven buoyancy regulating system disclosed in prior art has fluid pressure buoyancy adjustment formula and water hydraulic buoyancy to adjust
Joint formula two kinds.
Chinese invention patent CN102079375 A, (Central China science and technology is big for Master's thesis " oil-pocket buoyancy regulation device development "
Learn, Fang Xu) disclosed in fluid pressure buoyancy regulating system as it is shown in figure 1, mainly include interior outer container, check valve, solenoid directional control valve,
Bidirectional hydraulic pump, motor etc., wherein outer container is annular seal space, is placed in the surrounding medium outside device case；Remaining part is put
In device case.Inner pressurd vessel is non-tight circle chamber, it is ensured that balance each other with pressure in device case.When motor-driven hydraulic pumps is suitable
When hour hands (or counterclockwise) rotate, pump, from outer container oil suction, is pressed into inner pressurd vessel by check valve, and outer container volume reduces, it is achieved
Dive；When (or clockwise) rotates motor-driven hydraulic pumps counterclockwise, pump obtains electric from inner pressurd vessel oil suction, solenoid directional control valve, liquid
Force feed is pressed into outer container by the left position of reversal valve, and outer container volume increases, it is achieved float.
In dive and floating-upward process, inside and outside container pressure variation tendency is as in figure 2 it is shown, the change of inner pressurd vessel pressure is much smaller than outward
Container.During floating, the operating pressure of hydraulic pump need to be enough to overcome water depth pressure, therefore for deep-sea situation, hydraulic pump works pressure
Must be sufficiently high；During dive, outer container pressure relatively inner pressurd vessel is high, i.e. the inlet pressure of pump is higher than outlet pressure, and hydraulic oil can be straight
Connect press-in inner pressurd vessel, but in order to control diving speed, motor must apply an opposing torque, stops dive of overrunning, deep sea pressure energy
It is not effectively utilized；Additionally, because pressure is low in housing, be deep sea pressure outside housing, thus deep for sea, and housing need to hold
By high pressure, it is not easy to miniaturization.
