[0025] See also Figure 1-7 , as shown in the figure: This embodiment is a preferred implementation scheme in the present technical scheme, a power engineering cable protection device, comprising a cable body 1; one end of the two cable bodies 1 is respectively sleeved with a first connecting ring 2 and a second connecting ring 3, one end of the first connecting ring 2 and the second connecting ring 3 is respectively fixedly connected with a ferrule 4, the two ferrules 4 are respectively tightly fitted on the outer walls of the two cable bodies 1, the other end of the second connecting ring 3 is fixedly connected with a sealing ring 6, one end of the sealing ring 6 is plugged into one end of the first connecting ring 2, and two L-shaped rods 10 are fixedly connected to the inner wall of the sealing ring 6, the other end of the L-shaped rod 10 is fixedly connected with a fixing head 11, one end of the L-shaped rod 10 extends to the inside of the first connecting ring 2, and one end of the fixing head 11 is plugged into the inside of the first connecting ring 2.

[0026] like Figure 2 , 5 As shown, one end of the first connecting ring 2 is provided with a mounting groove 7 matching the sealing ring 6, and one end of the sealing ring 6 is inserted into the mounting groove 7. By inserting one end of the sealing ring 6 into the mounting groove 7 provided in the first connecting ring 2, the sealing ring 6 extends toward the interior of the first connecting ring 2, thereby sealing the connecting portion between the first connecting ring 2 and the second connecting ring 3.

[0027] like Figure 3 , 7 As shown, a through opening 8 is longitudinally opened inside the first connecting ring 2, and the L-shaped rod 10 and the fixing head 11 extend downward through the through opening 8 respectively. The through opening 8 opened on the inner wall of the first connecting ring 2 is used for the L-shaped rod 10 and the fixing head 11 to extend downward through the through opening 8.

[0028] like Figure 3 , 7As shown, a fixing groove 9 is horizontally opened on the inner wall of the first connecting ring 2, and the fixing groove 9 is opposite to the fixing head 11. The bottom end of the through-port 8 is connected with one end of the fixing groove 9, and one end of the fixing head 11 extends into the fixing groove 9. The fixing groove 9 opened on the inner wall of the first connecting ring 2 is connected with the through-port 8, so that the fixing head 11 moves into the fixing groove 9, so that the fixing head 11 is constrained inside the first connecting ring 2.

[0029] like Figure 6 As shown, a notch 12 is provided at one end of the first connecting ring 2 , and the upper end of the L-shaped rod 10 fits in the notch 12 . The notch 12 provided at one end of the first connecting ring 2 is used for hiding and moving the L-shaped rod 10 .
