Description
Technical field
The present invention relates to Buoyancy Control Technique field, specifically a kind of dilatation reduces density increase buoyant device.
Background technology
The power that the object being immersed in liquid or gas is held in the palm straight up by liquid or gas is called buoyancy, according to A Ji meter
For moral principle it is recognised that in liquid or identical gas density, displacement and capacity determine the size of buoyancy, institute
Buoyancy can be increased suitably to expand buoyant device volume, but the buoyant device on current aircraft and submariner device is often all
It is the device of constant volume, it is impossible to the buoyancy of aircraft or submariner device is adjusted flexibly, the hang time of aircraft is short, using very not
Flexibly.
The content of the invention
Goal of the invention the defects of being to overcome described in background technology of the present invention, so as to realize a kind of energy consumption it is relatively low,
The buoyancy that flexibly can quickly adjust aircraft or submariner device, that the dilatation for the hang time for extending aircraft reduces density increase is floating
Power apparatus.
For achieving the above object, the technical scheme is that：A kind of dilatation reduces density increase buoyant device, bag
Including left and right metal hemisphere and connect the ripple film of left and right metal hemisphere, the relative direction that fastens of the left and right metal hemisphere is set,
Left and right metal hemisphere is sealed connected together by ripple film；The centre position of ripple film is fixed between the left and right metal hemisphere
It is provided with electric machine support, installation settings has a motor with reductor on the electric machine support, outside the speed reducer output shaft
Connect double Worm gear mechanisms；Left spiral shell is fixedly installed respectively along the left and right metal hemisphere summit madial wall in ripple film telescopic direction
Bar and right screw rod, and left and right screw rod coordinates installation with double turbine mechanisms, forms double worm and gear structure.
As the preferred technical solution of the present invention, each wave bottom of the ripple film is fixedly installed support ring,
Each support ring mutually be arranged in parallel.
As the preferred technical solution of the present invention, the left and right metal hemisphere is titanium alloy material metal hemisphere.
As the preferred technical solution of the present invention, the ripple film is carbon fibre materials ripple film.
As the preferred technical solution of the present invention, along the left and right metal hemisphere summit madial wall in ripple film telescopic direction
Upper to be fixedly installed left and right screw support block respectively, left and right screw rod one end is fixedly installed on left and right screw support block respectively.
The dilatation of the present invention reduces the operation principle of density increase buoyant device：
This buoyant device is sealing, and inside is isolated from the outside, and during work, motor drives two turbines rotations, left and right spiral shell
Bar and turbine composition turbine and worm structure, most red motor drive left screw rod to be promoted to the left side, and right screw rod promotes to the right, makes
The right hemisphere of titanium alloy is moved to the right, and titanium alloy left hemisphere is moved to the left side, and now ripple film is just softened, and is finally moved to
The end of left and right screw rod, it will expand whole device volume and be twice the above, due to being sealing, external fluid can not enter interior
Portion, so the result that volume expansion is twice the above causes the density of whole device to reduce, so as to reach the purpose of increase buoyancy.
The dilatation of the present invention reduces the beneficial effect of density increase buoyant device：
1. the dilatation of the present invention reduces density increase buoyant device, each wave bottom of ripple film is fixedly installed support
Ring so that whole device has the enough pressure for withstanding external fluid, will not deform, and sturdy and durable, service life is longer.
2. the dilatation of the present invention reduces density increase buoyant device, driven simultaneously using motor, double turbine and worm mechanisms
Dynamic two screw rods in left and right rotate, and flexibly can quickly adjust the volume of buoyant device, both can guarantee that enough driving forces, and can is certainly
Lock, therefore whole mechanism will not expend too many electric energy, while can be by controlling motor rotating and the position rotated very
The size of convenient regulation buoyancy.
3. the dilatation of the present invention reduces density increase buoyant device, use multiple can be also tied so that buoyancy changes
Variable accumulation expands at double, and adjusting range is more wide in range.
Brief description of the drawings
The dilatation that Fig. 1 is the present invention reduces density increase buoyant device structural representation.
In figure：The left metal hemisphere of 1-, the right metal hemisphere of 2-, 3- ripple films, 4- electric machine supports, 5- motors, the left spiral shells of 6-
Bar, the right screw rods of 7-, 8- support rings, the left screw support blocks of 9-, the right screw support blocks of 10-.
