The side of fixed seat 1 is equipped with fixed strip 12, handle groove 14 is set in the outside of fixed strip 12, handle groove 14 is used to carry the equipment whole body conveniently.

[0036] The rotating shaft 3 is fixed outside the rotating seat 2, and the revetment net 4 is wound outside the rotating shaft 3. The revetment net 4 is fixedly connected with the cross rod 15 at one end away from the rotating shaft 3. The cross rod 15 is used to integrate the other end of the revetment net 4, so as to facilitate the use of the revetment net 4. The first positioning hole 13 is arranged at both ends of the fixed strip 12, and the second positioning hole 16 is arranged at both ends of the cross rod 15. The anchor rod cooperates with the first positioning hole 13 and the second positioning hole 16, so as to fix the equipment on the foundation pit slope. The limiting groove 17 is arranged at both ends of the rotating seat 2, and cooperates with the cross rod 15. After the revetment net 4 is wound, the cross rod 15 is located in the limiting groove 17, so as to limit and store the cross rod 15.

[0037] In one aspect of the embodiment, the two sides of the rotating seat 2 are respectively provided with an elastic winding assembly and an anti-shrinkage limiting assembly. The elastic winding assembly is used to drive the rotating shaft 3 to rotate and simultaneously shrink and wind the revetment net 4. The elastic winding assembly comprises a fixed ring 5 and a coil spring 6. The fixed ring 5 is fixed on one side of the rotating seat 2, and one end of the rotating shaft 3 is located in the fixed ring 5. One end of the coil spring 6 is fixed to the inner wall of the fixed ring 5, and the other end is fixed to the outer side of the rotating shaft 3. When the revetment net 4 is pulled, the rotating shaft 3 is driven to rotate, thereby driving the one end of the coil spring 6 connected with the rotating shaft 3 to rotate, and the coil spring 6 is compressed, so that the coil spring 6 exerts a reverse rotating force on the rotating shaft 3. When the revetment net 4 is not pulled, the rotating shaft 3 is reversely rotated under the elastic force of the coil spring 6, thereby driving the revetment net 4 to be quickly wound, completing the storage operation of the revetment net 4, and avoiding manual folding, which improves the storage efficiency and reduces the probability of damage to the revetment net 4 during storage.

[0038] In one aspect of the embodiment, the anti-shrink limiting assembly is used to limit the rotation of the rotating shaft 3.

The clamping block 11 is fixed on the bottom of the L-shaped plate 9, and the clamping block 11 is clamped with the toothed disc 7. By clamping the toothed disc 7 with the clamping block 11, the toothed disc 7 cannot rotate after the slope protection net 4 is expanded, so that the rotating shaft 3 cannot rotate, and the device cannot automatically store the slope protection net 4 by the action of the coil spring 6. The bottom of the clamping block 11 and the toothed groove on the outside of the toothed disc 7 are provided with mutually matched inclined surface structures. By the action of the inclined surface structure, when the slope protection net 4 is expanded, the toothed disc 7 can lift the clamping block 11, so as to achieve the purpose of not hindering the expansion of the slope protection net 4. After the slope protection net 4 is expanded, the toothed disc 7 and the rotating shaft 3 cannot automatically rotate back under the action of the coil spring 6.

[0039] Working principle:

[0040] In use, first, the anchor rod is inserted into the first positioning hole 13 inside, so as to fix the fixed seat 1 in the inside of the foundation pit, then rotate the rotating seat 2, so that the rotating seat 2 is attached to the angle of the foundation pit slope, then expand the slope protection net 4 by pulling the cross bar 15;

[0041] By the action of the inclined surface structure, when the slope protection net 4 is expanded, the toothed disc 7 can lift the clamping block 11, so as to achieve the purpose of not hindering the expansion of the slope protection net 4. When the size of the slope protection net 4 is enough to cover the foundation pit slope, the anchor rod is inserted into the second positioning hole 16 inside the two ends of the cross bar 15, so as to fix the cross bar 15 on the slope, and make the slope protection net 4 close to the slope, so as to protect the slope, and avoid the situation of rolling stones;

[0042] When the slope support is not needed, the anchor rod inside the second positioning hole 16 is removed, and the L-shaped plate 9 is pushed upward by hand, the spring 10 is pressed, and the L-shaped plate 9 drives the clamping block 11 to disengage from the toothed groove outside the toothed disc 7, then the rotating shaft 3 is reversely rotated under the action of the coil spring 6, so as to drive the slope protection net 4 to be quickly wound, complete the storage operation of the slope protection net 4, and then no manual folding is needed, not only improves the storage efficiency, but also reduces the probability of damage to the slope protection net 4 in the storage process;

[0043] After the revetment net 4 is wound up, the two ends of the horizontal rod 15 are placed in the limiting groove 17, then the rotating seat 2 is turned into the fixed seat 1, and then the equipment can be carried through the handle groove 14, which is convenient and practical.
