Problems solved by technology

[0002] With the development of the marine economy, submarine cable products such as submarine cables, submarine optical cables, and submarine photoelectric composite cables are widely used in offshore oil platforms and offshore wind power. Sliding, causing the cable to fail to work normally. In order to solve this problem, there are many kinds of submarine cable platform fixing devices, but most of the existing fixing devices can only fix one or two layers of submarine cable armored steel wire. The existing Chinese patent CN201420808606. 3 discloses a double-layer armored submarine cable platform fixing device. A number of backing plates and pressure plates are arranged in the protective cover and are superimposed on each other, and the first layer and the second layer of armor are respectively tightly pressed between the backing plates and the pressure plates. Steel wire, then connect the backing plate, pressure plate, and protective cover to the base through long screws, and fix them with lock nuts
When encountering a cable with four layers of armored steel wires, only one or two layers of armored steel wires are fixed, which cannot ensure the safety and reliability of the submarine cable. The third and fourth layers of armored steel wire are not only complicated in structure and cumbersome to install, but also need to double the length of the screw, and because the weight of the four-layer cable armored steel wire is twice as heavy as that of the two-layer cable armored wire, it is bound to be four layers. The armored steel wire of the cable puts more pressure on the long screw, which is easy to cause the long screw to bend, making the submarine cable weak in stability and low in tensile strength, which cannot ensure the safety of the submarine cable

Abstract

The invention discloses a fixing device and a fixing method for a submarine cable with four layers of armored steel wires. The fixing device is characterized in that the device includes a submarine cable and a fixed body; the submarine cable is provided with four layers of armored steel wires and a submarine cable core at one end, fixing rings are respectively arranged on at least two layers of armored steel wires, the armored steel wires are bent inward or outward and clamp the fixing rings, and the armored steel wires after fixing are an inverted truncated cone; the fixed body is provided with an installation hole connected with the outside and a cable hole at one end; the fixed body is internally provided with an inner cavity with an inverted truncated cone, the inner cavity is communicated with the cable hole, one end of the submarine cable is placed in the inner cavity, and the outermost layer of armored steel wire is matched with the inner wall of the fixed body; and a fixed plate with a glue pouring hole is arranged at the other end of the fixed body, and the fixed plate is connected to the fixed body through threads. The advantage is that: because the inner cavity and the armored steel wire after anchoring are inverted truncated cones, the outermost layer of the submarine cable fixed in the inner cavity can be connected with the inner wall of the fixed body more closelywhen the submarine cable is pulled downward by its own gravity.
