Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As mentioned in the background art, the deepwater sensing devices for transmitting various kinds of observation data can only be deployed in a short period of time and cannot be deployed in a full deepwater area for a long time, so that offshore energy, communication and the like cannot be deeply transmitted to the deepwater area, and the deployment, maintenance and recovery costs are high, and the safety and reliability are relatively poor. At present, sensing detection equipment is fixed on a submarine cable through a bearing type electric or photoelectric composite cable, sensing detection and communication transmission can be realized, although the sensing detection equipment is arranged in a full-depth water area for a long time, the bearing capacity of the submarine cable is less than 100 tons, the sea condition resistance is poor, and permanent real-time and in-situ detection cannot be realized.

Therefore, how to transmit energy and communication on the water surface to the deep sea and provide a real-time long-term in-situ sensing and detecting means for environmental monitoring under deep and distant sea water will become an improved direction of the application. In view of the above, the embodiments of the present application provide a polyester cable for sensoring integrated deep water mooring.

Please refer to fig. 1 to 8, which show the specific structure of the sensing integral deep water mooring polyester cable of the present application.

As shown in fig. 1 and fig. 2, the sensing-sensing integrated deep water mooring polyester cable comprises a first protective layer 1, an intermediate layer 2, a first filter layer 3 and a core layer 4 which are sequentially arranged from outside to inside; the middle layer 2 is provided with a sensing communication cable, the sensing communication cable comprises a cable 21 and a plurality of detection sensing devices 22, and circuit boards inside the detection sensing devices 22 are sequentially connected through power supply core wires in the cable 21.

The sensing and sensing integrated deep water mooring polyester cable not only has the bearing function, but also integrates the functions of deep sensing detection, communication transmission, energy supply and the like. The core layer 4, the first filter layer 3 and the first protective layer 1 form a polyester cable basic structure, so that the bearing and the strength guarantee are realized. The sensing equipment transmits data to the floating platform in real time and transmits the data back to the shore base in modes of satellite communication, Beidou and the like. The cable 21 supplies the surface energy to the subsea equipment while transmitting various data of the subsea equipment to the surface.

Wherein, the cable 21 and the detection sensing device 22 are arranged in a chain manner, and the detection sensing device 22 and the cable 21 are coaxially vulcanized. In order to prevent the bulge of the detection sensing device 22 and the cable 21 during the integration process with the polyester cable, the outer diameters of the detection sensing device 22 and the cable 21 are designed to have a uniform size.

The probe sensing device 22 includes a temperature probe 222 and a depth probe 223. The temperature probe 222 and the depth probe 223 of the detection sensing device 22 need to be in contact with the marine environment, so that a hole is formed in the lower end of the detection sensing device to ensure that information of the marine environment can be detected and sensed.

It should be noted that the first protective layer 1 is a woven protective sleeve; the first filter layer 3 is made of woven sand polyester fabric, and the core layer 4 is made of polyester engineering fiber. The sandwich layer 4 bears the pulling force, and first filter layer 3 can prevent that 3-5um and bigger granule from getting into sandwich layer 4 and producing wearing and tearing, and first protective layer 1 is wear-resisting, protection sensing communication cable.

In a preferred embodiment, as shown in fig. 3, a second filter layer 5 is disposed between the first protective layer 1 and the middle layer 2, and a second protective layer 6 is disposed between the middle layer 2 and the first filter layer 3. The second filter layer 5 can prevent 3-5um and larger particles from entering the sensing communication cable to cause abrasion; the second protective layer 6 is wear resistant and protects the core layer 4.

In a further preferred embodiment, as shown in fig. 4 and 5, a sub-cable 7 is provided between the core layer 4 and the first filter layer 3. The sub-cables 7 may further enhance the load-bearing properties of the deep water moored polyester cable.

In the above embodiment, the sensing communication cable is spirally wound on the first filter layer 3.

The method for spirally winding the cable 21 and the detection sensing device 22 is shown in fig. 6, and the winding distance of the sensing communication cable needs to take the elongation of the polyester cable into consideration. Through accurate calculation, the cable 21 and the detection sensing device 22 are prevented from being damaged due to longitudinal tension under the condition that the polyester cable is subjected to tension.

The following is an analytical determination of the winding pitch and helix angle of the sensing communication cable.

Stretching change of the polyester cable:

the polyester cable is abstracted as a model, and as shown in fig. 7, the polyester cable is regarded as a line, and any point on the sensing communication cable moves up and down along with the extension and contraction of the length of the cable. With the lowest as the origin of coordinates, then the displacement is in [ y ]₀：y²]To change between. Maximum length of displacement of y₂-y₀＝y₀*R_l。

Effect of polyester cable stretch:

maximum elongation R of polyester cable_lSetting the original length L of the polyester cable, the original length L 'after stretching, the original diameter D and the diameter D' after stretching, and obtaining the following formula according to the volume invariance principle:

when not stretched, the diameter is D, the winding angle is alpha, one winding can be simplified to the model shown in FIG. 8, the front view of one winding can be regarded as the half length of the circle, and the diameter of the circle isThe length of the sensing and communication cable wound by one circle is as follows:

the pitch of the winding is:

when stretched, L ═ L₀*(1+R_l) As analyzed above, then the length of the communication cable needs to be sensed to become

From the above analysis, it can be seen that the larger the expansion and contraction ratio, the larger the diameter change, and the larger the length change of the polyester cable. The longer the sensing communication cable needs to be wound. The larger the helix angle and pitch, the shorter the length of the sensing communication cable and vice versa.

Therefore, on the first filter layer 3, the sensing communication cable is provided with a spiral angle and a pitch wound at the detection sensing device 22, which are larger than those wound at the position where the detection sensing device 22 is not provided. The first assurance can make cable 21 not atress when tensile, and the second assurance detects sensing equipment 22 and places with the sandwich layer 4 syntropy of polyester cable, and first protective layer 1 can not be to detecting sensing equipment 22 cause great extrusion force.

Finally determining according to the expansion and contraction rate of the polyester cable, wherein the spiral angle of the sensing and communication cable is 45-75 degrees, and the thread pitch is 50-100 cm.
