The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention. In the following description, for clarity of presentation of the structure and operation of the present invention, description will be made with reference to the accompanying drawings by means of various directional words, but words such as "front", "rear", "left", "right", "upper", "lower" and the like should be interpreted as words of convenience and not as limiting words.
1-2, including a hull, an air bag positioned in the hull, a front cover mounted to one end of the hull, and a rear cover mounted to the other end of the hull; the cabin body comprises a shell with spiral drainage grooves on the inner wall and flange plates arranged at two ends of the shell; the air bag comprises a pipe body made of rubber, an air inlet end which is connected to the pipe body in a liquid sealing way and is close to the front cover, and an water inlet end which is connected to the pipe body in a liquid sealing way and is close to the rear cover; an air inlet groove is formed in one end, facing the outside of the pipe body, of the air inlet end head, and a vent hole communicated with the pipe body is formed in the bottom of the air inlet groove; the inner end of the front cover is provided with an air inlet inner ring which is in airtight connection with the air inlet groove, and the outer end of the front cover is provided with an air inlet and outlet joint which is communicated with the air vent and used for air inlet and outlet; the inner end of the front cover is arranged on an air inlet outer ring in liquid-tight fit with the inner wall of the shell, and a front gap for water supply circulation is formed between the air inlet outer ring and the end face adjacent to the air inlet joint; the outer end of the front cover is provided with a drainage joint communicated with the front gap; a water inlet groove is formed in one end, facing the outside of the pipe body, of the water inlet end head; the inner end of the rear cover is provided with a water inlet inner ring in liquid-tight connection with the water inlet groove, and the outer end of the rear cover is provided with a water inlet joint communicated with the water inlet groove and used for water inlet; the inner end of the rear cover is provided with a water inlet outer ring in liquid-tight fit with the inner wall of the shell, and a rear gap for water supply circulation is formed between the water inlet outer ring and the end face adjacent to the water inlet joint; at least one water through hole communicated with the rear gap is arranged on the water inlet inner ring.
Wherein, the shell and the flange plate are split parts, and obviously can be integrally formed into an integral part by welding or screwing. The water inlet joint is connected with the pipe body in an adhesive mode, and obviously can be connected with the pipe body in a hot melting mode. The air inlet joint and the pipe body are connected in an adhesive mode, and obviously can be connected in a hot melting mode. The front cover is connected with the cabin body through bolts, and obviously clamping and the like can also be adopted. The rear cover is connected with the cabin body through bolts, and obviously clamping and the like can also be adopted. The pipe body is made of vulcanized rubber, and obviously, the pipe body is made of plastic or silica gel. The drain tank preferably adopts a double-spiral structure. When the air bag is rapidly enlarged, and the drainage joint is only arranged at one end, the drainage effect of the double-head drainage groove is stronger than that of the single-head drainage groove, and the drainage speed is faster and more thorough. The shell belongs to a slender thin-wall part, and the double-head spiral drainage groove is adopted to meet the requirements of drainage rate, process superiority and working strength.
The inner wall of the shell is provided with the drainage groove, and when the air bag is enlarged after the air inlet connector is opened and the outer wall of the air bag is completely attached to the inner wall of the shell, the water medium is quickly discharged to the drainage connector along the drainage groove of the inner wall of the shell through the clearance between the shell and the air bag, so that the quick effectiveness of the water discharge of the buoyancy adjusting device is achieved.
When the buoyancy is required to be increased for the underwater device, the air inlet and outlet connectors are used for air inlet, the air bags are enlarged and are tightly attached to the inner wall of the shell, the water discharge connectors are opened, water medium is rapidly and thoroughly discharged from the water discharge connectors along the water discharge grooves, and the buoyancy is increased; when the buoyancy of the underwater device needs to be reduced, the water inlet connector is used for water inlet, the air inlet and outlet connector is opened, the air bag is extruded and then air is discharged from the air inlet and outlet connector, and the buoyancy is reduced. When the buoyancy reaches the requirement, the air inlet and outlet joint and the water inlet joint are closed, so that the stability of the buoyancy is realized. The exhaust joint adopts a two-way positive and negative pressure vacuum pump to realize air intake and exhaust, and the air exhaust/inflation function of the pump is controlled by an electromagnetic valve.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
