Description
Technical field
The utility model relates to a kind of watertight joint box, relates in particular to a kind of under-water robot pressure adaptive watertight joint box.
Background technology
Under-water robot has crucial effect to the exploitation of marine resources.The watertight joint box is important on the under-water robot, critical component, generally all adopts the structure of external pressure compensator.Oil-filled watertight joint box communicates with external pressure compensator through oil circuit.When being stressed; The suffered external pressure of watertight joint box and pressure compensator is greater than interior pressure, and watertight joint box's metal cabinet deformation can not take place, and external pressure compensator is owing to receiving external pressure that deformation takes place; Oil in the pressure compensator gets in the oil-filled casing of watertight joint box; Oily total amount in the oil-filled casing increases, and has remedied the VOLUME LOSS of oil-filled casing inner fluid because of reducing by compression, makes watertight joint box and external pressure compensator internal and external pressure balance.The watertight joint box of external pressure compensator form need carry out the installation of pressure compensator and the laying of oil circuit; There are potential faults such as fuel clogging, corrosion leakage and external compensator breakage, in seawater, are easy to generate the inefficacy of crackle build-up of pressure compensator like the leather bag pressure compensator.
Adopt the built-in form of pressure compensator can avoid above problem.Chinese patent CN101804856 A discloses a kind of compensation-film oil-filled connection box for deep submergence vehicle; This patent adopts the plastic sheeting compensation way of film by way of compensation; Compensation film and oil-filled casing are formed built-in pressure compensator, and the deformation through compensation film compensates in the oil-filled metal cabinet because pressure changes the fluid volume change that causes, the plastic material compensation film that this patent adopts is damaged easily; The inefficacy of build-up of pressure compensator; And do not adopt redundant compensation method, and only adopting the compensation way of compensation film, in a single day compensation film goes wrong and will cause whole watertight joint box's inefficacy.
Summary of the invention
The purpose of the utility model provides a kind of under-water robot pressure adaptive watertight joint box.
The utility model solves the technical scheme that its technical matters adopted:
The utility model comprises metal cabinet, flange, sealing band, compensation film, pressing plate, protective cover, bolt, underwater electrical connector, plug, quick joint, piston-type pressure compensator, fuel feed hole and oil outlet.The wall of metal cabinet is equipped with underwater electrical connector, quick joint, plug and piston-type pressure compensator, and there are fuel feed hole and oil outlet in the metal cabinet bottom surface, and the end face port of metal cabinet is equipped with flange; Compensation film places on the flange; Between compensation film and the flange sealing band is installed, pressing plate is installed on the compensation film, protective cover is installed on the pressing plate again; Said compensation film, pressing plate, protective cover and flange are tightly connected through bolted, and said protective cover has through hole.The compensation film of metal cabinet end face is a platinum/titanium metal thin film, in the watertight joint box, fills the compensation oil with capacity, and compensation oil is formed built-in metallic film type pressure compensator with compensation film, works simultaneously with the piston-type pressure compensator.
The beneficial effect of the utility model is: the utility model is equipped with the piston-type pressure compensator on the metal box body wall; One end of piston and inner oil pocket are connected; An other end and outer water environmental communication, inside and outside can promote piston motion when having pressure reduction, thereby change the interior oil cavity volume; Oil liquid pressure in the watertight joint box changes with the variation of oil chamber volume, presses with external pressure in making to keep balance.The piston-type pressure compensator makes the interior pressure of watertight joint box a little more than external pressure, effectively avoids penetration of sea water in the watertight joint box.The compensation film at metal cabinet top is a platinum/titanium metal thin film; In the watertight joint box, fill compensation oil with capacity; Compensation oil is formed built-in metallic film type pressure compensator with compensation film; Compensation film can produce deformation along with inside and outside differential pressure, and the oil liquid pressure in the watertight joint box changes self-equalizing joint box external and internal pressure with the variation of oil chamber volume.Platinum/titanium metal thin film ductility is good, and deformation range is big, not cracky.The utility model need not external pressure compensator and oil circuit, adopts redundant compensation method, and two pressure compensators are worked simultaneously, watertight joint box reliable operation.
