One end of the protective net 3 is slidably mounted on the winding drum 1 and fixedly connected to the rotating roller 8. The winding drum 1 is provided with a rotating mechanism to facilitate the winding and unwinding of the protective net 3. A connecting frame 4 is fixed to the end of the protective net 3, and the winding drum 1 is provided with a connecting mechanism for connecting and fixing multiple protective nets 3. By setting up the winding drum 1, the protective net 3, the rotating roller 8, and the rotating mechanism, the rotating mechanism can drive the rotating roller 8 to rotate, and the rotation of the rotating roller 8 realizes the winding and unwinding of the protective net 3, which is convenient for carrying and placing the protective net 3, and also convenient for pulling out and deploying the protective net 3. By setting up the connecting frame 4 and the connecting mechanism, the cooperation between the connecting mechanism and the connecting frame 4 can realize the fixing of multiple protective nets 3, which can effectively avoid the problem of gaps between multiple protective nets 3 affecting the protective effect.

[0020] Reference Figure 3 and Figure 4 The rotating mechanism includes a worm gear 10 fixedly installed at the end of the take-up roller, a worm 9 rotatably installed on the take-up roller, a rotating plate fixed at the end of the worm 9, and the worm 9 meshing with the worm gear 10. By setting the worm 9 and the worm gear 10, the rotation of the worm 9 drives the worm gear 10 to rotate, and the rotation of the worm gear 10 drives the take-up roller to rotate, thus performing the winding and unwinding work on the protective net 3. At the same time, the worm 9 and the worm gear 10 can perform a self-locking function to avoid the problem of the protective net 3 shaking during winding and unwinding, thereby improving stability.

[0021] Reference Figure 1 and Figure 2The connecting frame 4 is equipped with multiple fixing rods 5 for inserting into the road slope base. The connecting frame 4 is also equipped with an adjustment mechanism for adjusting the insertion depth of the fixing rods 5. By setting the fixing rods 5 and inserting them into the road slope base, the connecting frame 4 and the protective net 3 can be installed simultaneously, while also providing auxiliary support to the slope base.

[0022] Reference Figure 1 and Figure 2 The adjustment mechanism includes a threaded rod 12 threadedly mounted on the connecting frame 4. One end of the threaded rod 12 is fixed with a handle, and the end of the fixing rod 5 is fixedly connected to the other end of the threaded rod 12. By setting the threaded rod 12, the threaded rod 12 rotates on the connecting frame 4, and at the same time, the threaded rod 12 drives the fixing rod 5 to move synchronously, so that the fixing rod 5 can be inserted into the slope base, thereby improving the stability of the fixing rod 5.

[0023] Reference Figure 1 The connecting mechanism includes a connecting plate 2 fixedly installed on the surface of the winding drum 1. The connecting frame 4 has a slot for the connecting plate 2 to be inserted into, and the connecting plate 2 has a threaded hole that cooperates with the fixing rod 15. By setting the connecting plate 2, the connecting plate 2 can be inserted into the connecting frame 4 and snapped into the connecting frame 4 for installation. At the same time, the threaded rod 12 can simultaneously fix the connecting plate 2, thereby realizing the installation of multiple protective nets 3.

[0024] Reference Figure 1 One side of the connecting frame 4 is provided with a fixing rod 7 for insertion into the ground for fixation. By inserting the fixing rod 7 into the ground, the protective net 3 can be further supported and fixed in case the road slope collapses, thus preventing the protective net 3 from collapsing synchronously with the slope.

A mounting plate 11 is rotatably mounted on the bottom end of the connecting rod 6. A second fixing rod 7 is fixed on the mounting plate 11. By setting the connecting rod 6 and the mounting plate 11, the connecting frame 4 and the second fixing rod 7 are connected. When the slope collapses and causes the protective net 3 and the connecting frame 4 to tilt, the connecting rod 6 can simultaneously drive the second fixing rod 7 to insert deeper into the ground for support, reducing the possibility of the protective net 3 and the connecting frame 4 tilting and collapsing.

[0026] Reference Figure 1 The protective net 3 is composed of multiple steel wire ropes that are intertwined and connected for support, which can effectively improve the support effect of the protective net 3.

[0027] Working principle: Rotating the threaded rod 12 fixes the fixing rod 5 inside the road slope base, thus fixing the connecting frame 4. The fixing rod 7 is inserted into the ground. Then, by rotating the worm gear 9, the worm gear 9 drives the worm wheel 10 to rotate, causing the rotating roller 8 to rotate and unwind the protective net 3, thus protecting the road slope base. The connecting plate 2 on the side of the protective net 3 is inserted into the connecting frame 4 on the side of another protective net 3, thus splicing and installing multiple protective nets 3 to achieve a larger area of ​​protection.
