The guide frame adopts a special semicircular shape. Through the special design of its structure and shape, the optical cable can slide smoothly in and out of the cabin, avoiding damage to the optical cable or wiring obstruction caused by excessive friction, thereby solving the problems existing in the transportation of traditional optical cables between cabins, improving the laying efficiency and quality, and reducing costs.

[0031] In order to more clearly illustrate the technical solution of the present invention, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1 As shown, the present invention provides a guide frame for submarine cables to enter and exit the cabin, wherein the guide frame 10 is arranged on both sides of the hatch, and the two ends of the guide frame 10 are respectively connected to the optical cable transmission port. The guide frame 10 is connected to the optical cable guide rail 83 above it, and the submarine cable is stored in the lower optical cable cabin 70. During use, the submarine cable enters and exits the optical cable cabin 70 through the roller slide 60; the cross section of the guide frame 10 is semicircular, and through the shape and slope of the special curved surface, the submarine cable can slide smoothly during the wiring process, avoiding damage to the submarine cable or wiring obstruction caused by excessive friction, improving the laying efficiency and quality, and reducing costs; this design not only improves the efficiency of submarine cable wiring, but also extends the service life of the submarine cable, and improves the reliability and safety of the submarine cable.

[0032] The guide frame 10 is mainly assembled from arc steel pipes 2, connecting pipes 7 and supporting steel pipes 3; the arc steel pipes 2 are installed on the cabin floor 4 through the supporting steel pipes 3, and the arc steel pipes 2 are evenly distributed on the connecting pipes 7. There are multiple connecting pipes 7, which are arranged in parallel on the semicircular arc surface, with good stability and short construction period. Diagonal braces Ⅰ5 are set between the supporting steel pipes 3 on the upper end surface of the cabin floor 4, and diagonal braces Ⅱ6 are set between the supporting steel pipes 3 on the upper end surface of the cabin floor 4 and the arc steel pipes 2 to increase structural stability; the supporting steel pipes 3 on the lower end surface of the cabin floor 4 are parallel to each other, and the arc steel pipes 2 are connected and supported to prevent the arc steel pipes 2 from losing stability.

[0033] like Figure 2As shown, the side view of the guide frame shows that the cross-section of the arc surface formed by the guide frame is a semicircle, and the center of the circle is located at the cabin floor 4 where the guide frame 10 is located. Through the special design of the curved surface shape of the guide frame 10, the submarine cable can slide from the lower cable cabin 70 to the main cable outlet without any hindrance; when both ends of the submarine cable are in the cable guide rail 83 and the middle section is in the lower cargo hold 70, the middle section can be slid to the cable guide rail 83 without any hindrance by pulling the two ends in the cable guide rail 83; when one end of the submarine cable is in the cable guide rail 83 and the rest including the other end is in the lower cable cabin 70, the rest can be pulled into the cable guide rail 83 through the curved surface shape of the guide frame 10 by pulling the end in the cable guide rail 83.

[0034] like Figure 4 As shown, assuming that the radius of the semicircle in the side view is R and the thickness of the cabin floor 4 is T, the height of the highest point of the guide frame 10, i.e., the edge of the optical cable guide rail 83, from the cabin floor 4 is H, and the relationship between H and R is: ; Through the special curved surface design of the guide frame 10, the submarine cable can slide smoothly from the lower cable compartment 70 to the cable guide rail 83 of the upper compartment, avoiding the transmission obstruction in the traditional submarine cable laying process and improving the laying efficiency.

[0035] The horizontal distance from the highest point of the guide frame 10 to the edge of the cabin floor 4 is D, and the condition that D satisfies is: ; The installation condition of the horizontal distance D greatly facilitates the welding installation of the guide frame, and avoids the guide frame 10 being damaged due to structural instability caused by welding at a random position.

[0036] like Figure 3 As shown, it is a connection structure between the guide frame 10 and the cable drum slide 60. The cable drum slide 60 is assembled by a bottom bracket 1 and an outer bracket 62. The outer bracket 62 is arranged on one side of the bottom bracket 1 of the cable drum slide 60; the steel frame 8 is arranged on the other side of the bottom bracket 1 of the cable drum slide 60. A connecting pipe 12 is welded to one end of the guide frame 10, and the connecting pipe 12 is welded and fixed to the steel frame 8. The connecting pipe 12 is respectively connected to the guide frame 10 and the cable drum slide 60 by welding, so as to realize a perfect transition between the guide frame 10 and the cable drum slide 60; the cable drum slide 60 is installed on the lower cable cabin 70. The steel frame 8 and the outer bracket 62 of the cable drum slide 60 together form the guardrails on both sides of the drum slide, so as to ensure that the submarine cable can enter and exit the lower cable cabin 70 along the predetermined track. The drum 61 can reduce the sliding resistance of the submarine cable, which can protect the submarine cable and reduce the labor intensity of the workers.

[0037] When laying a submarine cable, a repeater is required every 80 kilometers for signal enhancement. The mass of the repeater is so large that a crane is needed to lay the repeater. The repeater 82 is stored in a repeater storage box 81 next to the cable guide 83. The cables at both ends of the repeater are located in the cable cabin 70.

[0038] like Figure 5 to Figure 11 As shown, the method for using the guide frame for entering and exiting a submarine optical cable for a cable-laying ship comprises the following steps: Step 1: If Figure 5 As shown, the laying of the submarine cable begins. A repeater 82 is lifted out of the repeater storage box 81 by a crane to the position shown in the figure, and the wheel-movable cable barge 80 pulls the optical cable on the left side of the repeater 82 along the submarine cable guide 83 toward the left stern. The submarine cable was originally stored in the cable cabin 70 on the lower floor, and its length is very long, so the situation that both sides of the submarine cable are in the cable guide 83 and the middle part is stranded in the cable cabin 70; Step 2: If Figure 6 As shown in FIG. 1 , the wheel-movable cable-barge device 80 continues to pull the left side of the submarine cable toward the stern, and the submarine cable will slide along the guide frame 10 of the present invention into the cable guide rail 83, forming a Figure 7 The state shown is that all the submarine cables on the left side of the repeater are moved into the cable guide 83; Step 3: If Figure 8 As shown, the wheel-movable cable barge 80 continues to pull the left submarine cable of the repeater 82 toward the left stern, and at the same time, the crane lifts the repeater 82 on the cable guide rail 83 along with the left submarine cable of the repeater, and at this time, the right submarine cable of the repeater is still stranded in the lower cable cabin 70; Step 4: If Fig. 9 As shown, the wheel-movable cable barge 80 continues to pull the left submarine cable of the repeater 82 toward the left stern, and at the same time, the crane hoists the repeater 82 to the cable guide rail 83 and moves toward the left stern. The right submarine cable of the repeater 82 will slide along the guide frame 10 of the present invention into the cable guide rail 83, forming Fig.10 State, that is, the repeater is hoisted into the cable guide rail 83, and the submarine cables on both sides are also transported into the cable guide rail 83, such as Fig.11 .
