Cable protection device for water conservancy and hydropower engineering

The utility model relates to the technical field of cable protection equipment, in particular to a cable protection device for water conservancy and hydropower engineering. The cross-shaped sliding groove is formed in the base, the movable and fixable sliding block is arranged in the sliding groove, and the protection cylinder capable of rotating around the bearing is arranged on the sliding block and used for protecting the cable. When in use, the device can be arranged at the corner, and a cable is directly placed in the protective cylinder, so that the cable can be pulled to slide in the protective cylinder when being laid and pulled, and the cable is prevented from being in direct contact with the corner to cause scraping; and the cable can also be fixed in the protective cylinder through the rubber pad, so that the cable is prevented from sliding. And meanwhile, the cable has a certain moving range on the base, and can rotate and move relatively, so that the relative direction of the cable is changed. Th
