Abstract
An underwater optical cable and electric cable seal device includes a subbase (1) connected with a photoelectron hatch cover (7) and is characterized in that the subbase (1) is provided with a screw thread end cap (3), an O-shaped seal ring (2) is arranged between the subbase (1) and the screw thread end cap (3), an outer liner is sleeved to the screw thread end cap (3), and a silastic seal cushion (4) used for deformingly squeezing on the optical cable (8) is arranged between the inner cavity of the outer liner (6) and an external end face of the screw thread end cap (3). The seal device has advantages of simple technique for processing, low cost, short manufacturing cycle, convenient maintenance and low cost of rehabilitation; when the optical cable or electric cable or the seal device is damaged or fault, it is easy to disassemble and replace.
Description
Technical field
The utility model relates to a kind of underwater sealing device, especially a kind of device that is used for the underwater optical cable sealing, specifically a kind of sealing device of optical cable under water.
Background technology
At present, underwater operation equipment is stationary monitoring base station, underwater robot etc. under water, they need with carry out communication and control on the bank, therefore need a large amount of electric connectors and (light) cable.Traditional cable and electric connector sealing generally all take the heat cure method, but there are very big problem in this method: at first, the rate of finished products of sulfuration cost costliness, product is not high and the manufacturing cycle is longer; Secondly, the sulfuration sealant is easy to wear out and damage medium-term and long-term placement of air; Moreover, in case the sulfuration sealant be damaged or lost efficacy, the rehabilitation cost height, the cycle is long.Especially, some plastic outer layer communication cable as optical cable or optical cable etc., can not be taked the vulcanization process sealing technically.
Summary of the invention
The purpose of this utility model is the cost height that sealing exists at existing underwater optical cable, and the cycle is long, problem such as can not repair, and it is good to design a kind of versatility, and cost is low, makes and uses all optical cable sealing devices under water very easily of installation.
The technical solution of the utility model is:
A kind of sealing device of optical cable under water, it comprises the base 1 that links to each other with photoelectron hatchcover 7, it is characterized in that being equipped with on the base 1 thread ending cover 3, between base 1 and the thread ending cover 3 O RunddichtringO 2 is installed, be installed with overcoat 6 on the thread ending cover 3, between the outer face of the inner chamber of overcoat 6 and thread ending cover 3, be equipped with and be used to be out of shape the silicone rubber seal pad 4 that is squeezed on the optical cable 8.
Also fill up at the intracavity bottom of described overcoat 6 metal caul 5 is housed.
All be processed with the V-shaped groove of reinforced seal effect on contacted of described end cap 3, overcoat 6 and metal caul 5 and silicone rubber seal pad 4.
The internal diameter of described silicone rubber seal pad 4 is than the little 0.1～0.2mm of external diameter of optical cable.
The beneficial effects of the utility model:
(1) processing technology is simple, with low cost, the manufacturing cycle short.Be used for the occasion higher to seal request, the Mold Making of silicone rubber seal pad is used for the occasions lower to seal request such as shallow water, can make of simple and easy method.
(2) at the equal machning v grooves of contact-making surface of end cap, overcoat and metal caul and silicone rubber seal pad, good sealing effect.
(3) at the bottom of easy to maintenance, the rehabilitation cost, when optical cable or damaging appears in sealing device or be easy to dismounting during fault and change.
(4) the utility model fields such as monitoring base station, subaqueous survey buoy and underwater operation robot under water have wide practical use.
(5) the utility model process 1MPa, the hydraulic test of 30min and 60 meters depth of waters, the 24h water test proves that its sealing effectiveness is good, can satisfy actual instructions for use fully.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of sealing device of optical cable under water, it comprises the base 1 that links to each other with photoelectron hatchcover 7, O RunddichtringO 2, thread ending cover 3, silicone rubber seal pad 4 and overcoat 6, base 1 can link to each other with photoelectron hatchcover 7 by welding, thread ending cover 3 is fixedly linked by securing member (screw) and base 1, O RunddichtringO 2 is installed between base 1 and the thread ending cover 3 to be leaked to prevent thread ending cover 3 and base 1 junction, be installed with overcoat 6 on the thread ending cover 3, between the outer face of the inner chamber of overcoat 6 and thread ending cover 3, be equipped with and be used to be out of shape the silicone rubber seal pad 4 that is squeezed on the optical cable 8, be preferably in when specifically implementing between the inner chamber bottom surface of silicone rubber seal pad 4 and overcoat 6 metal caul 5 is installed.Optical cable 8 passes overcoat 6, metal caul 5, silicone rubber seal pad 4, thread ending cover 3 and base 1 and enters in the cabin body 7, overcoat 6 moves to the rotation of cabin body direction along the fine thread of end cap 3, with 4 compressions of silicone rubber seal pad, make it all have certain decrement, reach sealing function at front/rear end and each face of Internal and external cycle.When overcoat 6 when the external screw thread of end cap 3 screws, metal caul 5 produces the rotational slide effect between overcoat 6 and silicone rubber seal pad 4, prevent that silicone rubber seal pad 4 from being sprained.
Also can on end cap 3, overcoat 6 and metal caul 5 and silicone rubber seal pad 4 contacted, all be processed with the V-shaped groove of reinforced seal effect during concrete enforcement.Simultaneously the internal diameter of silicone rubber seal pad 4 should be than the external diameter of optical cable little 0.1～0.2mm, so both can guarantee sealing effectiveness, again can be so that the installation of optical cable and sealing device.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
