[0020] according to Figure 1 As shown, a cable tunnel safety protection device comprises a protection plate body 1, electric lifting columns 2 are fixedly arranged at both ends of the bottom of the protection plate body 1, a base 3 is fixedly arranged at the bottom of the electric lifting columns 2, a moving component 4 is fixedly arranged at the bottom of the base 3, a mounting groove 11 is arranged at the top of the protection plate body 1, a buffer component 5 is fixedly arranged in the mounting groove 11, and a buffer plate 6 is fixedly arranged on the top of the buffer component 5; two electric lifting columns 2 are respectively arranged at the bottom of both ends of the protection plate body 1, and a force block 8 is fixedly arranged between the protruding ends of the two electric lifting columns 2 and the protection plate body 1; a diagonal brace 7 is fixedly arranged on the inner side of the fixed end of the electric lifting column 2 and the base 3; the curvature of the buffer plate 6, the arc-shaped connecting plate 56 and the protection plate body 1 are consistent.

[0021] In a specific implementation, the protective plate body 1, the buffer plate 6 and the arc-shaped connecting plate 56 can all be set to an arc shape with the same curvature. The buffer plate 6 is set above the protective plate body 1 through the buffer assembly 5. Electric lifting columns 2 are set at both ends of the bottom of the protective plate body 1. The overall height of the protective plate body 1 can be adjusted through the electric lifting columns 2 to meet the needs of cable tunnels of various heights. The force block 8 can evenly distribute the force of extending and retracting the electric lifting column 2 to the bottom of both ends of the protective plate body 1 when the electric lifting column 2 rises and falls, thereby improving the stability of the protective plate body 1 when adjusting the height. The diagonal brace 7 can be set at 45° on the inner side of the electric lifting column 2 and the top of the base 3. The stability of the support of the electric lifting column 2 is further increased by the diagonal brace 7. When the device needs to be moved, the moving assembly 4 can extend from the bottom of the base 3 and prop up the device to move the device. After moving to a suitable position, the moving assembly 4 is retracted to the bottom of the base 3, and the base 3 is used to improve the stability of the device when it is fixed.

[0022] according to Figure 2 and Figure 3 As shown, the buffer assembly 5 includes a sliding shaft 52 and a slider 53. The sliding shaft 52 can be set to two. Both ends of the two sliding shafts 52 are fixedly provided with a fixed block 51. The two sliding shafts 52 are fixedly provided in the mounting groove 11 through the fixed block 51. The slider 53 can be set to two and two through holes are opened on both sides of the slider 53. The two sliders 53 are slidably provided on the two sliding shafts 52 through the two through holes. The two sliding shafts 52 are respectively sleeved with a return spring 1 54 and a return spring 2 541. One end of the return spring 1 54 is fixedly connected to the fixed block 51, and the other end is fixedly connected to the outer side of the slider 53. Both ends of the return spring 2 541 are respectively fixedly connected to the inner sides of the two sliders 53. A connecting block 55 is rotatably provided on the top of the two sliders 53. The other end of the connecting block 55 is rotatably connected to an arc-shaped connecting plate 56. The arc-shaped connecting plate 56 is fixedly provided at the bottom of the buffer plate 6.

[0023] In specific implementation, a connecting block 55 is rotatably provided on the top of the two sliders 53, and the tops of the two connecting blocks 55 are rotatably connected to the bottom of the buffer plate 6. When rocks and other debris fall from the top of the cable tunnel, the rocks and other debris first contact the buffer plate 6, and the force of the rocks falling downward causes the buffer plate 6 to move toward the protective plate body 1. During the downward movement of the buffer plate 6, the two connecting blocks 55 move outward, and during the movement, the two sliders 53 slide toward the two ends of the sliding shaft 52 respectively. During the sliding movement of the slider 53 toward the two ends of the sliding shaft 52, the return spring 1 54 is affected by the movement of the slider 53. The extrusion shortens the distance, and the reverse elastic force generated when the return spring 1 54 is squeezed can slow down the speed of the slider 53 moving toward the sliding shaft 52. At the same time, the two ends of the return spring 2 541 are respectively subjected to the pulling force generated when the two sliders 53 move outward. The contraction force of the return spring 2 541 is used to further slow down the speed of the two sliders 53 moving toward the two ends of the sliding shaft 52. When the return spring 1 54 and the return spring 2 541 release energy, they drive the two sliders 53 to move to the middle position of the sliding shaft 52. The two sliders 53 moving toward the middle prop up the two connecting blocks 55, and then prop up the buffer plate 6.

[0024] according to Figure 4 As shown, a contraction groove 31 is opened at the bottom of the base 3, and the moving component 4 is fixedly arranged in the contraction groove 31; the moving component 4 includes an electric telescopic column 41, and the electric telescopic column 41 can be arranged in plurality, and the fixed end of the electric telescopic column 41 is fixedly arranged in the contraction groove 31, and the extended end of the electric telescopic column 41 is arranged toward the ground and a universal wheel 42 is fixedly arranged on the extended end.

[0025] In specific implementation, the number of electric telescopic columns 41 and the number of universal wheels 42 can be adjusted according to actual conditions. In the present embodiment, four electric telescopic columns 41 and universal wheels 42 are provided in each retractable groove 31. When the device needs to be moved, the electric telescopic column 41 is controlled to extend, and the extended electric telescopic column 41 extends the universal wheel 42 from the retractable groove 31 so that the base 3 and the entire device are lifted off the ground. The worker can then push the device to move the device. After moving to the appropriate position, the electric telescopic column 41 contracts and retracts the universal wheel 42 into the retractable groove 31 so that the universal wheel 42 is suspended in the air. At this time, the bottom of the base 3 is in contact with the ground. The purpose of supporting the entire device is achieved by the contact between the base 3 and the ground, thereby increasing the stability of the device during use.
