Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the oil-filled pipeline of sealing that the present invention mainly consists of upper shielded-plate tube 3 and lower shielded-plate tube 5 and the feeder 2 of pipeline inside form.The corrosion resistant light aluminum alloy material of employing of upper shielded-plate tube 3 and lower shielded-plate tube 5.Guaranteeing on the basis of communication distance, the length of upper shielded-plate tube 3 and lower shielded-plate tube 5 and the distance between upper and lower shielded-plate tube are determined according to antenna gain theoretical calculation formula.Between upper shielded-plate tube 3 and lower shielded-plate tube 5, by nylon tube connector 4, utilize and be threaded, between upper shielded-plate tube 3, lower shielded-plate tube 5 and tube connector 4, by rubbery flat gasket circle, realize sealing.
Upper shielded-plate tube 3 tops are end cover 1, and end cover 1 is threaded connection with upper shielded-plate tube 3, utilizes plain washer to seal, and goes up shielded-plate tube 3 top drillings simultaneously as oil-filled hole.Lower shielded-plate tube 5 bottoms have the compensating pipe 5b of mounting seat 5a and close position base.On compensating pipe 5b, be connected with transition joint 9.Bottom tube 7 is fixedly connected with by set bolt 6 with the mounting seat 5a of lower shielded-plate tube 5, and sealing between the two realizes by radial and axial two seals circle 14.Antenna connection seat 8 is commercially available underwater electrical connector, and it is drawn two wires and is communicated with feeder 2 and lower shielded-plate tube 5 respectively, impedance requirement and the antenna match of cable buttock line.
Feeder 2 adopts the copper wire same with water surface antenna.For guaranteeing to insulate between feeder 2 and upper and lower shielded-plate tube, in its outer wrap one deck oil resistant thermoplastic sleeve pipe (not shown), the root of thermoplastic sleeve pipe is cast by epoxy resin 13, be fixedly connected with and locate with the mounting seat 5a of lower shielded-plate tube 5, guarantee insulation completely between part feeder 2 and upper shielded-plate tube 3 and lower shielded-plate tube 5.
For guaranteeing that the antenna casing and the seawater that consist of end cover 1, upper shielded-plate tube 3, lower shielded-plate tube 5 and transition joint 9 insulate, after end cover 1, upper shielded-plate tube 3, lower shielded-plate tube 5 and transition joint 9 installations are connected, at outer surface, carry out integral body sulfuration, sulfuric horizon should be fitted completely with antenna casing part, pore-free.Meanwhile, bottom tube 7 and transition joint 9 are nonmetallic materials, guarantee insulation.
For guaranteeing that antenna can bear high pressure, between feeder 2 and antenna casing, be full of insulating oil.The external rubber compensation of transition joint 9 oil pipe 11, rubber compensation oil pipe 11 is interior oil-filled, redeeming under hyperbaric environment.Rubber compensation oil pipe 11 is oil resistant oil pipes, tubing length (compensating oily volume) is determined according to the cubical contraction of antenna under maximum pressure, pipe clamp 10a fixing seal is passed through with transition joint 9 in one end of rubber compensation oil pipe 11, other end utilization silently 12 and pipe clamp 10b fixing seal.
The principle that oil subsidy of the present invention is repaid is as follows: compensation oil pipe is connected with shielded-plate tube, when antenna is under water time, Water Pressure, in the outer wall of compensation oil pipe, is delivered to antenna inside by flexible pipe by hydraulic pressure, make whole system external and internal pressure identical, and change and automatically regulate with submerged depth.Like this, antenna system still can design according to a conventional method, needn't consider the impact of hydraulic pressure, greatly reduces physical dimension and the weight of system, with the obvious advantage in the design of hyperbaric environment.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
