Device for expanding volume, reducing density and increasing buoyancy

Abstract

The invention relates to the field of buoyancy control, and in particular, relates to a device for expanding volume, reducing density and increasing buoyancy, wherein the device includes a left metalhemisphere, a right metal hemisphere and a corrugated film connecting the left metal hemisphere and the right metal hemisphere. The left metal hemisphere and the right metal hemisphere are arranged ina relative buckling direction, and the left metal hemisphere and the right metal hemisphere are sealedly connected together by the corrugated film; a middle position, between the left metal hemisphere and the right metal hemisphere, of the corrugated film is fixedly provided with a motor support; the motor support is equipped with a drive motor with a speed reducer, and an output shaft of the speed reducer is externally connected with a double-worm gear mechanism; the inner side walls of the top points of the left metal hemisphere and the right metal hemisphere in the corrugated film stretching direction are fixedly provided with a left screw rod and a right screw rod respectively. The device for expanding volume, reducing density and increasing buoyancy can adjust the volume of a buoyancy device flexibly and rapidly, and also can be self locked, so the whole mechanism cannot consume too much electric energy, and meanwhile, the buoyancy can be easily adjusted by controlling positive and negative rotation and a rotation position of the driving motor.

Description

technical field [0001] The invention relates to the technical field of buoyancy control, in particular to a buoyancy device for expanding capacity, reducing density and increasing buoyancy. Background technique [0002] The force that an object immersed in a liquid or gas is lifted vertically upward by the liquid or gas is called buoyancy. According to Archimedes’ principle, we can know that when the density of the liquid or gas is the same, the displacement and displacement determine the buoyancy. Therefore, appropriately expanding the volume of the buoyancy device can increase the buoyancy. However, the buoyancy devices on the current aircraft and submersibles are often fixed-volume devices, which cannot flexibly adjust the buoyancy of the aircraft or submersible. flexible. Contents of the invention [0003] The purpose of the present invention is to overcome the defects described in the background technology, so as to realize a buoyancy device with low energy consumpti...
