[0024] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to their rights.

[0025] Example 1, with reference to Figure 1-3 , a cable laying and protection device, the device comprising;

[0026] At least two cable tubes 1, the number of which can be selected according to the cable laying length, for example, three, etc. The cable tubes 1 are seamless steel tubes, and their inner diameter can be selected according to the use requirements. The axes of the two adjacent cable tubes 1 are collinear, and the space inside the cable tubes 1 forms a cable laying channel;

[0027] In order to improve the protection of the cables between the two adjacent cables, we set up a protective mechanism, which includes a curved cover plate 2, a U-shaped connecting lock 3 and a connecting bottom plate 4. The cable tube 1 is located between the curved cover plate 2 and the connecting bottom plate 4; the curved cover plate 2 spans the top of the two cable tubes 1, and the curved cover plate 2 is formed into a roughly curved plate-like structure. The curved cover plate 2 is set upside down, referring to Figure 3 The bottom surface of the U-shaped connecting lock 3 is fitted with the top surface of the arc-shaped cover plate 2, and the top inner peripheral surface of the U-shaped connecting lock 3 abuts against the top outer peripheral surface of the arc-shaped cover plate 2. The bottom of the U-shaped connecting lock 3 passes through the connecting base plate 4, and the connecting base plate 4 is formed into a roughly square plate-shaped structure. An external thread that can be screwed with an external bolt fastener is also provided on the outer peripheral surface of the U-shaped connecting lock 3 extending out of the connecting base plate 4, so as to lock the arc-shaped cover plate 2 between the U-shaped connecting lock 3 and the connecting base plate 4. The U-shaped connecting lock 3 is formed into a roughly U-shaped shape, and its middle area is formed as an arc surface that can fit with the outer peripheral surface of the arc-shaped cover plate 2, and its two ends are arranged parallel to each other.

[0028] The flat steel cable bracket 5 is formed into a roughly plate-like structure. One end of the flat steel cable bracket 5 is placed inside the end of the cable tube 1, and the other end extends out of the cable tube 1 and extends vertically downward to have an arc-shaped bend. The arc-shaped bend is formed into a roughly arc-shaped plate-like structure to reduce friction when the cable passes through this part. The flat steel cable bracket 5 is horizontally fixed to the inner peripheral edge of the end of the cable tube 1, and its top surface is smoothly connected to the inner peripheral surface of the cable tube 1;

[0029] The flat steel cable bracket 5 is used to tie the cable to the top surface of the flat steel cable bracket 5, so as to relatively fix the cable to prevent it from moving;

[0030] The support angle steel 6 and the pad 7, the top end of the support angle steel 6 is fixedly connected to the bottom outer peripheral surface of the cable tube 1, and the bottom end is vertically fixed on the top surface of the pad 7. The outer wall of the support angle steel 6 can be welded and fixed to the outer peripheral surface of the cable tube 1, and the bottom surface of the pad 7 forms a contact surface with the ground. The pad 7 is formed into a roughly square plate-like structure. The bottom surface of the pad 7 can be welded and fixed to the ship deck. Two groups of the support angle steels 6 are provided on the outer peripheral surfaces of the front and rear ends of the cable tube 1, and the support angle steel 6 bracket is an L-shaped structure.

[0031] The process of using the cable laying and protection device is as follows:

[0032] (1) Preparation stage: according to the length of the cable laying and the required number of cable pipes 1, select the appropriate length and inner diameter of seamless steel pipe as the cable pipe 1, determine the layout of the cable pipe 1, ensure that the axis of the two adjacent cable pipes 1 is collinear to form a continuous cable laying channel, prepare the arc-shaped cover plate 2, U-shaped connecting lock 3 and connecting bottom plate 4 required by the protection mechanism, as well as the flat steel cable support 5, support angle steel 6 and base plate 7 and other accessories;

[0033] (2) Install the cable pipe 1: place the cable pipe 1 on the ground or ship deck according to the predetermined layout, ensure that the cable pipes 1 maintain appropriate spacing and collinearity, install two sets of support angle steels 6 on the outer peripheral surface of the front and rear ends of the cable pipe 1 respectively, the top end of the support angle steel 6 is fixedly connected with the bottom outer peripheral surface of the cable pipe 1, and the bottom end is fixedly connected with the top surface of the base plate 7, the outer wall of the support angle steel 6 can be fixed with the outer peripheral surface of the cable pipe 1 by welding or other methods, and the base plate 7 is fixed on the ground or ship deck to ensure that the bottom surface of the base plate 7 is in close contact with the contact surface, which can be fixed by welding or other methods;

[0034] (3) Install the protection mechanism: place the arc-shaped cover plate 2 across the top of the two adjacent cable pipes 1, ensure that the bottom surface of the arc-shaped cover plate 2 is in close contact with the top surface of the cable pipe 1, abut the top inner peripheral surface of the U-shaped connecting lock 3 on the top outer peripheral surface of the arc-shaped cover plate 2, and pass the bottom of the U-shaped connecting lock 3 through the connecting bottom plate 4, and install external bolt fasteners on the outer peripheral surface of the U-shaped connecting lock 3 extending out of the connecting bottom plate 4 and tighten them to lock the arc-shaped cover plate 2 between the U-shaped connecting lock 3 and the connecting bottom plate 4;

[0035] (4) Laying cable: start laying the cable from one end of the cable pipe 1 and gradually push forward along the cable laying channel, use binding tape and other tools to bind the cable to the top surface of the flat steel cable support 5 during the cable laying process to ensure that the cable remains in a fixed state, and after completing the cable laying, check the cable pipe 1, protection mechanism, flat steel cable support 5 and support angle steel 6 and other components to ensure that all components are firmly installed and have no loose parts.

[0036] Compared with the traditional cable protection structure, the cable laying and protection device forms a cable laying channel by using at least two cable pipes 1 with collinear axes, and sets a protection mechanism above the cable pipe 1, which can effectively prevent the cable from being damaged by external mechanical damage, especially avoiding the problem that the metal cable hose rusts and becomes brittle due to sea moisture and salt corrosion, so that it cannot continue to protect the cable, thereby improving the integrity and service life of the cable to a certain extent.
