[0032] Please refer to Figures 1-4 A kind of cable protection device suitable for coal mine electromechanical equipment in the embodiment, including cover 1, the upper surface of the cover 1 two sides symmetry integration is connected with a pair of mounting frame 4 by fastening screw installation in mine top wall, mounting frame 4 is equipped with fastening hole being passed through by fastening screw, the fixing of mounting frame 4 realizes that overall protection device is hoisted in the top wall of mine, the upper surface of mounting frame 4 front and back side are all installed and fixed with a pair of symmetrically arranged telescopic rod 5, the bottom of telescopic rod 5 is extension end.

[0033] The extension end is fixedly installed with a movable cover 2 for sealing the lower end opening of the cover 1. The telescopic rod 5 is composed of a plurality of hollow cylinders which are in sliding communication with each other, wherein the topmost and bottommost hollow cylinders are connected with the mounting frame 4 and the movable cover 2 respectively, so as to drive the movable cover 2 to move when the telescopic rod 5 is stretched or contracted. The abutting surface of the cover 1 and the movable cover 2 is provided with a sealing rubber strip. The sealing rubber strip ensures that the abutting surface is fully sealed when the cover 1 and the movable cover 2 are abutted, thereby preventing the entry of coal mine dust.
