Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to a floating laying device for armored optical fiber composite cables. Background Technology

[0002] With the increasingly widespread and in-depth development of aquatic resources, the number of engineering projects operating on water is increasing. These projects often require work in open waters spanning hundreds or even thousands of meters. During these operations, communication and power are transmitted via fiber optic composite cables, which offer significantly higher transmission efficiency than copper cables, while also providing excellent safety and strong anti-interference capabilities. Therefore, they are widely used for power and signal transmission between offshore vessels and shore-based equipment. Metal armor is used to protect the internal cables, giving them high compressive and tensile strength, and resistance to harsh environments.

[0003] However, during water operations, vessels or work platforms need to move frequently within a small range due to the operational requirements, making it impossible to lay the fiber optic composite cable underwater. To prevent the fiber optic composite cable from accidentally scraping against underwater structures and damaging the cable during the movement of the water platform, it is necessary to design a floating deployment device for armored fiber optic composite cables. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a floating deployment device for armored optoelectronic composite cables. It employs a dual-buoy structure, which, while fixed to the cable, provides positive buoyancy to keep the cable afloat on the water surface, effectively improving the safety of the optoelectronic composite cable.

[0005] Specifically, this utility model provides a floating deployment device for armored optical fiber composite cables, comprising:

[0006] external floating body;

[0007] The inner float is an inner air bladder located inside the outer float. The inner surface of the inner float is a cavity for accommodating the cable. When the inner float is inflated, it clamps the cable.

[0008] Furthermore, an air cylinder is detachably mounted on the outer float, and the air cylinder is connected to the inner float via an internal air pipe for inflating the inner float.

[0009] Furthermore, the outer float is provided with a gas cylinder placement cavity, the gas cylinder is placed in the gas cylinder placement cavity and fixed by an anti-loosening strap.

[0010] Furthermore, the internal air pipe is equipped with an internal air valve.

[0011] Furthermore, the outer float is an outer airbag with an external air pipe for connecting to an external air source to inflate the outer float.

[0012] Furthermore, the external air pipe is equipped with an external air valve and a pressure gauge, the pressure gauge being used to measure the air pressure of the external buoy.

[0013] Furthermore, both the outer and inner floating bodies are U-shaped structures and are arranged coaxially.

[0014] The working principle of this utility model:

[0015] Prepare the required number of deployment devices in advance on a flat surface or deck. Inflate the outer float of each deployment device via an external air hose, using a pressure gauge to measure the air pressure. Stop inflating when the pressure gauge reading reaches 0.02 MPa. Then, place the device on the cable and open the internal air valve, allowing the air cylinder to quickly inflate the inner float. Inflate until it tightly wraps around the cable. At this point, the cable and inner float are in close contact with each other, and the friction is high, making it difficult to move the device onto the cable. Then, close the internal air valve, securing the device firmly to the cable. Release the cable a short distance and repeat the above steps.

[0016] When retrieving the cable, simply open the vent of the inner float to release the gas inside, then remove the device and place it in a suitable retrieval location.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The device provided by this utility model adopts the method of inner and outer double airbags, which can effectively reduce the inflation preparation time and disassembly time before the experiment.

[0019] (2) The overall device of this utility model has high reliability and high flexibility, and can be adapted to different numbers of devices for different release lengths. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1-3 As shown, this embodiment provides a floating deployment device for armored optical fiber composite cables. Multiple of these devices are installed on the cable to provide positive buoyancy, allowing it to float on the water surface, thereby improving the safety of the cable. Specifically, each floating deployment device includes an outer float 1 and an inner float 2. The outer float 1 is a U-shaped high-strength external airbag with an external inflation port and an external air deflation port 11 at its two ends. The external inflation port is connected to an external air pipe 3. The external air pipe 3 is equipped with a pressure gauge 32 and an external air valve 31. The external air pipe 3 is connected to an external air source 33. The external float 1 is inflated through the air source 33, and the inflation of the U-shaped outer float 1 is controlled by the external air valve 31. The pressure gauge 32 measures the air pressure of the outer float 1. When the float is fully inflated and elastic when pressed, inflation can be stopped when the pressure gauge 32 shows a value of 0.02 MPa.

[0029] The inner float 2 is an inner air bladder located inside the outer float 1. The inner side of the inner float 2 is a cavity for accommodating the cable 5. It has an internal inflation port and an internal deflation port 21 at both ends. The internal inflation port is connected to a gas cylinder 41 via an internal air pipe 43, and an internal air valve 44 is installed on the internal air pipe 43 for inflation control. The gas cylinder 41 is installed in the gas cylinder placement cavity on the outer float 41 via an anti-loosening strap 42. The inner float 2 can be inflated through the gas cylinder 41 via the internal air valve 44. After inflation, it tightly wraps around the cable 5, resulting in close contact and high friction between the cable and the inner float 2. Closing the internal air valve 44 then secures the device to the cable 5.

[0030] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
