It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0025] See also Figures 1 to 7The preferred embodiment of the utility model provides a retractable shore power cable protection tool, which includes a roller 1, a roller support rod 2, a first tripod 3, a second tripod 4 and a connecting rod 5, wherein the first tripod 3 and the second tripod 4 are respectively arranged on both sides of the roller support rod 2, and the roller support rod 2 is rotatably connected to the upper end of the first tripod 3 and the upper end of the second tripod 4 respectively; the roller 1 is rotatably connected to the roller support rod 2, and the axial direction of the roller 1 is perpendicular to the laying direction of the shore power cable 12; the connecting rod 5 is connected between the first tripod 3 and the second tripod 4, and an angle can be formed between the first tripod 3 and the second tripod 4, and the angle can be locked by the connecting rod 5. Wherein, the first tripod 3 and the second tripod 4 are both composed of two support members 31 and a connecting rod 32, the two support members 31 are arranged in parallel, and the connecting rod 32 is fixedly connected between the two support members 31.

[0026] According to the retractable shore power cable protection tooling of the utility model, Figure 1 , Figures 5 to 7 As shown, when it is necessary to pull and apply the shore power cable 12 on the ship, the first tripod 3 and the second tripod 4 on both sides of the roller support rod 2 are first unfolded to form an angle between the first tripod 3 and the second tripod 4, and the angle is locked by the connecting rod 5, and then the shore power cable 12 is laid on the roller 1 to avoid direct contact between the shore power cable 12 and the ground, thereby avoiding high-temperature melting and scratches of the shore power cable 12; when it is not necessary to pull and apply the shore power cable 12, the locking of the connecting rod 5 on the angle formed between the first tripod 3 and the second tripod 4 is released, and the first tripod 3 and the second tripod 4 on both sides of the roller support rod 2 are folded and stored in the corresponding area on the ship. It can be seen that with the organic combination of the first tripod 3, the second tripod 4 and the connecting rod 5, the tooling can be quickly folded, the utilization rate of the space on the ship is improved, and the practicality is good. In addition, since the axial direction of the roller 1 is perpendicular to the laying direction of the shore power cable 12, and the roller 1 is rotatably connected to the roller support rod 2, when the operator pulls the cable from the ship, a rolling friction force is generated between the shore power cable 12 and the roller 1, thereby reducing the labor intensity of the staff when pulling and laying.
