Abstract
The utility model relates to a compensation film type oil-filled connection box for a deep diving submersible, which comprises a metal box body with water-tight sockets arranged on the front and the rear side surfaces, and is characterized in that an oil charge valve, an oil drain valve and a deflation valve are respectively arranged on the other side surfaces of the metal box body. A ring flange is hermetically arranged at the port of the box body; a compensation film is covered on the ring flange; a pressure plate is arranged on the compensation film; the pressure plate, the compensation film and the ring flange are connected tightly and hermetically; and a through-hole is formed in the middle of the pressure plate. In the utility model, the compensation film adopting a soft oil-proof plastic sheet is used to cover the top surface; sufficient compensation oil is filled in the connection box; the sufficient oil and the compensation film together constitute an internal compensator, so an external compensator and an oil pipe are not required, and the compensation film only has tensile deformation and is not damaged easily; besides, the connection box has the advantages of simple structure, reliability, practicability and very low cost.
Description
Technical field
The utility model relates to a kind of oil-filled junction box, in order to carry out gathering and transferring of electric wiring, can be widely used under the various compression resistance occasions, is particularly useful on all kinds of bathyscaphs that the degree of depth reaches thousands of meters.
Background technology
At present, the oil-filled junction box who uses on the domestic and international submersible all adopts the pressure compensation structure of external compensator.Establish an oil connection on the junction box, receive on the compensator by oil pipe, the compensation rate of this compensator is to be multiplied by the compression ratio of compensation oil under limiting pressure by the volume that calculates oil-filled junction box, adds certain nargin statistics.Oil-filled junction box and compensator oil circuit communicate, when pressurized, oil-filled junction box and compensator external pressure are greater than interior pressure, itself can not produce deformation oil-filled junction box, piston pressurized on the compensator is pushed ahead, and the oil in the compensator is clamp-oned in the oil-filled junction box, and the oily total amount in the oil-filled junction box increases, filled up the VOLUME LOSS that reduces because of oily pressurized compression, the inside and outside pressure of oil-filled junction box and compensator reaches balance.The oil-filled junction box of this form needs to carry out the installation of external compensator and the laying of oil pipe when mounted, also has potential faults such as oil pipe obstruction, corrosion leakage and the breakage of external compensator leather bag.
Summary of the invention
Volume, weight, mounting arrangements that exists at external compensator in the prior art and the problem that has aspect such as potential safety hazard, the applicant provides a kind of compensation-film oil-filled connection box for deep submergence vehicle, it need not external compensator and oil pipe, compensate film can tensile deformation, be not easy to destroy, and the junction box is simple in structure, and cost is very cheap.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Compensation-film oil-filled connection box for deep submergence vehicle, comprise metal cabinet, the lateral means watertight socket of metal cabinet, the side returning apparatus of described metal cabinet has oil charge valve, fuel outlet valve and vent valve, the port sealing device ring flange of casing, compensate film is covered on the ring flange, installs pressing plate on the compensate film, described pressing plate, compensate film and ring flange are fastened and connected, and described pressing plate middle part has through hole.Described compensate film is a flexible plastic sheet.
Technique effect of the present utility model is:
The utility model at its end face coated with the oil resistant plastics sheet of softness film by way of compensation, in the junction box, fill compensation oil with capacity, the oil of these capacities and compensate film are formed a built-in compensator together, need not external compensator and oil pipe, compensate film only has tensile deformation, be not easy to damage, and the junction box is simple in structure, reliable and practical, cost is very cheap.

Fig. 2 is a vertical view of the present utility model.
Fig. 3 is that the utility model is full of the front view of oil back under normal pressure.
Fig. 4 is that the utility model is full of behind the oil front view under high pressure.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
See Fig. 1, Fig. 2, the utility model comprises metal cabinet 2, its four walls and bottom surface adopt metallic plate to be welded, the forward and backward side wall surface of metal cabinet 2 all installs watertight socket 7, the side wall surface returning apparatus of metal cabinet 2 has oil charge valve 8, fuel outlet valve 1 and vent valve 9, " returning " font ring flange 3 of port welding of casing, " return " compensate film 4 of the flexible plastic sheet material of the about 3mm of cladding thickness on the ring flange 3 of shape, device " returning " font pressing plate 5 on the compensate film 4, pressing plate 5 middle parts have through hole.With hold-down bolt 6 that ring flange 3, compensate film 4 and pressing plate 5 sealings are fastening, flexible plastic sheet plays the effect of compensate film.
See Fig. 3, under normal pressure, after electric wiring connects in the junction box, oil-filled in the junction box by oil charge valve 8, open vent valve 9 exhausts simultaneously, when in the junction box, being full of oil and not having air substantially, vent valve 9 cuts out, continue in the junction box oil-filledly, reach the interior pressure of 0.4kg up to junction box's internal pressure, this moment, compensate film 4 was outwards heaved.
See Fig. 4, along with the submersible dive, the junction box is subjected to external pressure to be increased gradually, because metal cabinet 2 is rigid objects, and compensate film 4 is flexible materials, pressurized post-compensation 4 down falls into from the middle part gradually, compensation oil volume compression in the junction box, the interior pressure increases, up to interior, the external pressure balance, i.e. the accumulator box increase gradually that is subjected to external pressure by the compression of compensation oil volume and in press to increase offset or compensate (compensation oil can be compressed, and decrement probably is 7%-10%) under the certain pressure environment, this part volume compression remedies to lower recess by compensate film 4 pressurizeds, can not cause the distortion of metal cabinet 2 itself.
When latent device come-up, junction box's external pressure reduces, and the compensation oil volume in the junction box increases gradually, and compensate film slowly recovers the state heaved.Because in this process, compensate film is in the distortion state of stretching, contract always, and compensate film can not tear breakage at the tapping of hold-down bolt, therefore, requires the compensate film must oil resistant, and certain pliability should be arranged, and certain intensity is arranged again.
The utility model through surplus 60 times 71.5MPa voltage-withstand test checking, fully proves feasibility of the present utility model and reliability, and finds application on 7000 meters manned underwater vehicles.
