Abstract
The invention discloses a compensation-film oil-filled connection box for a deep submergence vehicle. The connection box comprises a metal box body of which the side face is provided with a water-tight socket. The connection box is characterized in that: the side face of the metal box body is also provided with an oil charge valve, an oil drain valve and an air release valve; a ring flange is hermetically arranged on the port of the box body; a compensation film is covered on the ring flange and is provided with a pressure plate; the pressure plate, the compensation film and the ring flange are tightly and hermetically connected with each other; and the middle part of the pressure plate is provided with a through hole. The top surface of the connection box is covered by a soft oil-resistant plastic sheet serving as the compensation film; the inside of the connection box is filled with enough compensation oil; and the enough oil and the compensation film form a built-in compensator so an externally connected compensator and an oil pipe are not needed. The compensation film only has tensile deformation and is unlikely to damage. The connection box has the advantages of simple structure, reliability and practicability and very low cost.
Description
Technical field
The present invention relates to a kind of oil-filled joint box,, can be widely used under the various compression resistance occasions, be particularly useful on all kinds of deep submergence vehicles that the degree of depth reaches thousands of meters in order to carry out gathering and transferring of electric wiring.
Background technology
At present, the oil-filled joint box who uses on the domestic and international submersible all adopts the pressure compensation structure of external compensator.Establish an oil connector on the joint box, receive on the compensator by oil pipe, the compensation rate of this compensator is to be multiplied by the bulk compressibility of compensation oil under ultimate pressure by the volume that calculates oil-filled joint box, adds certain nargin statistics.Oil-filled joint box and compensator oil circuit communicate, when pressurized, oil-filled joint box and compensator external pressure are greater than interior pressure, itself can not produce deformation oil-filled joint box, piston pressurized on the compensator is pushed ahead, and the oil in the compensator is clamp-oned in the oil-filled joint box, and the oily total amount in the oil-filled joint box increases, filled up the volume loss that reduces because of oily pressurized compression, the inside and outside pressure of oil-filled joint box and compensator reaches balance.The oil-filled joint 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 joint box is simple in structure, and cost is very cheap.
In order to solve the problems of the technologies described above, the present invention 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, oil cock and aie escape valve, the port sealing device flange of casing, compensate film is covered on the flange, installs pressing plate on the compensate film, described pressing plate, compensate film and 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 invention is:
The present invention at its end face coated with the oil resistant plastics sheet of softness film by way of compensation, in the joint 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 joint box is simple in structure, reliable and practical, cost is very cheap.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a birds-eye view of the present invention.
Fig. 3 is that the present invention is full of the front view of oil back under normal pressure.
Fig. 4 is that the present invention is full of behind the oil front view under high pressure.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
See Fig. 1, Fig. 2, the present invention includes metal cabinet 2, its four walls and bottom surface adopt metal sheet 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, oil cock 1 and aie escape valve 9, " returning " font 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 flange 3 of shape, device " returning " font pressing plate 5 on the compensate film 4, pressing plate 5 middle parts have through hole.With push bolt 6 that 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 joint box, oil-filled in the joint box by oil charge valve 8, open aie escape valve 9 exhausts simultaneously, when in the joint box, being full of oil and not having air substantially, aie escape valve 9 is closed, continue in the joint box oil-filledly, reach the interior pressure of 0.4kg up to joint box's internal pressure, this moment, compensate film 4 was outwards heaved.
See Fig. 4, along with the submersible dive, the joint 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 joint box, the interior pressure increases, up to interior, the external pressure balance, i.e. the storage battery 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 amount of compression 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, joint box's external pressure reduces, and the compensation oil volume in the joint 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 push bolt, therefore, requires the compensate film must oil resistant, and certain elasticity should be arranged, and certain intensity is arranged again.
The present invention through surplus 60 times 71.5MPa voltage-withstand test checking, fully proves feasibility of the present invention and reliability, and finds application on 7000 meters manned submersibles.
