Description
Technical field
It the utility model is related to a kind of wisdom energy for being used to connect the signal transmission of ground acoustic equipment and underwater installation
Low noise high tensile cable.
Background technology
The product is used for underwater sound device and the signal of underwater installation transmits, because cable can move with underwater sound device in water,
Therefore easily there is the problems such as swing, noise and sealing, therefore the requirement to cable is very high.The cable mainly has 4 keys
Point：1st, reduce as current or wave are swung；2nd, reduce the spray and encounter noise caused by cable；3rd, the waterproof of the termination of cable；
4th, hydraulic pressure easily causes shielding to scratch insulation and fail.
In order to reduce swing of the cable with current or wave, weight is hung below cable, therefore it is required that cable has
There is very high tensile strength.Traditional cable center is strengthened using steel wire, and creep extension occurs in this scheme, get rusty and causes electricity
The problems such as cable hardness increase, it is therefore desirable to use new strengthening core, not only to ensure that cable is soft and the construction of cable is stable, together
When to ensure that strengthening core can bear weight for a long time, it is therefore desirable to physical dimension to strengthening core and ability of weighing carry out accurate
Calculate, while the sheath of the cable needs have very high intensity and anti-tear performance, avoids sheath after bearing pulling force from ftractureing, therefore
Design new structure is needed to strengthen cable cover(ing).Common cable is all smooth surface, is occurred with spray collision very big
Noise, so as to influence the degree of accuracy of underwater detecting devices test result, it is therefore desirable to cable surface is improved, so as to
Reduce spray and noise caused by cable collision.Chloroprene rubber material has excellent elasticity, water resistance, mechanical performance and glued
Performance is tied, therefore the cable uses chloroprene rubber sheath, while cable connector also uses identical material, it is ensured that cable bonds good
It is good, so as to play waterproof effect.Underwater Pressure is very big, and brass wire shielding easily pierces through insulation, it is therefore necessary to special in structure
Design fails so as to avoid shielding layer of copper wires from scratching insulation.
Disclosed in Chinese patent ZL 200820223672.9《Oil well heater oil-resistant high-temperature high tensile cable》,
The centrally disposed twisted steel wire rope of cable improves the tensile property of cable, and can adapt in oil well high intensity uses ring
Border.But the cable is used to connect ground acoustic equipment and the signal of underwater installation transmits, cable not only requires very high
Tensile strength, while cable needs have a high flexibility, thus braided wires in water using easily make moist and get rusty and under intensity
Drop, while steel wire can cause cable hardness to increase considerably as strengthening core.
