[0016] Among them: a storm railing 1; a rotating shaft 2; a guide frame 3; a roller 4; an adjustable telescopic rod 5; an outer rod 5.1; an inner rod 5.2; a lock 5.3; and a ship deck 6. DETAILED DESCRIPTION

[0017] See also Figure 1 and Figure 2 The utility model relates to an anti-interference protection device for shore power cables, which is arranged on a stormproof railing 1, and includes a rotating shaft 2, a guide frame 3, a roller 4 and an adjustable telescopic rod 5. The stormproof railing 1 is fixed on a ship deck 6, and the rotating shaft 2 is fixedly arranged on the top of the stormproof railing 1 and welded to the stormproof railing 1 as a whole. The guide frame 3 is sleeved on the rotating shaft 2, and one end of the guide frame 3 extends outward, and the other end is connected to the adjustable telescopic rod 5. The adjustable telescopic rod 5 is vertically arranged on the inner side of the stormproof railing 1, and the lower end of the adjustable telescopic rod 5 is fixed on the ship deck 6 through an ear seat. The guide frame 3 is provided with rollers 4 at intervals along the extension direction, and the rollers 4 are rotatably arranged on the guide frame 3.

[0018] The adjustable telescopic rod 5 comprises an outer rod 5.1 and two inner rods 5.2, the two inner rods 5.2 are respectively arranged at the upper and lower ends of the outer rod 5.2, and a lock 5.3 is arranged between the inner rod and the outer rod, so that the upper and lower sections of the adjustable telescopic rod 5 can be flexibly adjusted, and the position is locked by the lock 5.3 after being adjusted to a suitable position, which is very simple and convenient for the crew to use. By adjusting the length of the adjustable telescopic rod 5, the guide frame 3 is driven to rotate along the rotating shaft 2, thereby adjusting the angle of the guide frame 3.
