The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Fig. 2; A kind of deep-sea underwater glider floatage actuating device comprises fuel tank 7, high-pressure plunger pump 4, gear type pump 8, pump drive motor 3,9, filter 5, small-sized normally closed solenoid valve 10, the baby check valve 2,6 that is installed in 17 li of pressure shells and is installed in pressure shell 17 exterior outer oil sacs 1 that hydraulic principle is as shown in Figure 1.Fuel tank 7 comprises shell 11, inner bellows-type leather bag 13, bottom opto-electronic pickup 12, stage casing opto-electronic pickup 14, top opto-electronic pickup 16 and mobile end cap 15.One end of bellows-type leather bag 13 and the bottom end seal of shell 11 are affixed, and 15 sealings of the other end and mobile end cap are affixed, move end cap 15 and are slidingly connected in the shell 11, can sway, realize oil-feed and oil extraction.Above-mentioned shell 11 is processed for aluminum alloy.
Outer oil sac 1 is in pressure shell 17 outsides, outside face and seawater direct contact, and it encloses 18 side seals with pressure shell 17 through O shape and is connected.
Outer oil sac 1 oil inlet links to each other with high-pressure plunger pump 4 oil outlets; High-pressure plunger pump 4 oil inlets link to each other with gear type pump 8 oil outlets; Gear type pump 8 oil inlets link to each other with fuel tank 7 oil outlets; Gear type pump 8 oil outlets link to each other with fuel tank 7 oil inlets through baby check valve 6 and do skimmer circuit, are aided with pump drive motor 3,9 and filter 5, constitute oil-discharging circuit jointly.Outer oil sac 1 oil outlet links to each other with fuel tank 7 oil inlets through small-sized normally closed solenoid valve 10, constitutes the oil-feed loop.
When the underwater glider rig ship for dive, small-sized normally closed solenoid valve 10 is opened, and under the effect of inside and outside differential pressure, hydraulic oil flows to fuel tank 7 from outer oil sac 1.Fluid is on the increase in the fuel tank 7, promotes bellows-type leather bag 13 to the top expansion, and when top opto-electronic pickup 16 detects when moving end cap 15 positions, small-sized normally closed solenoid valve 10 is closed in leather bag 13 arrival desired locations.At this moment, gravity is greater than buoyancy, underwater glider with fixed speed along the dive of zig-zag track.
When underwater glider was prepared come-up, pump drive motor 3,9 drove high-pressure plunger pump 4 and gear type pump 8 work respectively, and hydraulic oil is oil sac 1 outside filter 5 and baby check valve 2 flow into.Pump drive motor code-disc is measured the rotation number of turns of high-pressure plunger pump 4, passes to master control system, multiply by the fixed displacement of high-pressure plunger pump 4 revolutions again, can draw the oil extraction volume.The fluid volume constantly reduces in the fuel tank, makes the bellows-type leather bag shrink, and when bottom opto-electronic pickup 12 detects when moving end cap 15 positions, pump drive motor 3,9 quits work.At this moment, gravity is less than buoyancy, and underwater glider floats along the zig-zag volume with fixed speed.
In the working process, underwater glider can be opened pump drive motor 3,9 or small-sized normally closed solenoid valve 10, regulates the buoyancy size, thereby the athletic posture and the kinematic velocity of adjustment aerodone navigate by water according to desired trajectory.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
