DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4A water and soil erosion prevention protection structure comprises a first protective plate 1 and a second protective plate 2. The front and rear positions of the inner cavities of the first protective plate 1 and the second protective plate 2 are slidably connected with an extension plate 3. The first protective plate 1 and the second protective plate 2 are fixedly connected with a fixing box 4 on the opposite sides. The top of the inner cavity of the fixing box 4 is slidably connected with a threaded rod 5 through a bearing. Both sides of the inner cavity of the fixing box 4 are slidably connected with a limiting cone 6. The inner cavity of the limiting cone 6 is embedded with a threaded cylinder 7. The threaded rod 5 is threadedly connected with the threaded cylinder 7. By arranging the first protective plate 1, the second protective plate 2 and the extension plate 3, when the extension plate 3 is unfolded, the protection area can be adjusted. The protective area is expanded. When the extension plate 3 is closed into the first protective plate 1 and the second protective plate 2, the shielding capacity of the first protective plate 1 and the second protective plate 2 is increased. Then, through the fixing box 4, the threaded rod 5, the limiting cone 6, the threaded cylinder 7, the driven gear 8, the driving gear 9, the transmission rod 10 and the rotating handle 11, it is convenient for the user to fix the protective structure. The limiting cone 6 is inserted into the soil for fixing, which can have a good fixing effect, and solves the problem that the protective area of ​​the existing protective structure against soil erosion is fixed and cannot be adjusted according to the soil erosion protection, and the shielding strength of the protection cannot be adjusted, which affects the protective effect.

[0020] Specifically, a driven gear 8 is sleeved on the surface of the threaded rod 5 , and a driving gear 9 is meshed on the surface of the driven gear 8 .

[0021] Specifically, a transmission rod 10 is fixedly connected to the other side of the driving gear 9, and the other end of the transmission rod 10 passes through the fixed box 4 through a bearing and is fixedly connected to a turning handle 11. Through the arrangement of the driven gear 8, the driving gear 9, the transmission rod 10 and the turning handle 11, the threaded rod 5 can be driven to rotate, and the threaded rod 5 drives the limiting cone 6 to move downward.

[0022] Specifically, movable grooves 12 are provided at the front and rear positions of the inner cavities of the first protective plate 1 and the second protective plate 2, and the inner cavities of the movable grooves 12 are slidably connected with movable blocks 13, and one end of the movable block 13 away from the movable grooves 12 is fixedly connected to the extension plate 3. Through the setting of the movable grooves 12 and the movable blocks 13, the extension plate 3 can be limited and guided to improve the sliding performance.

[0023] Specifically, handles 14 are fixedly connected to the opposite sides of the inner cavities of the two fixed boxes 4, and the surfaces of the handles 14 are provided with anti-slip grooves. The provision of the handles 14 can facilitate users to carry the protective structure.

[0024] Specifically, both sides of the inner cavity of the fixed box 4 are provided with a slide groove 15, and the inner cavity of the slide groove 15 is slidably connected with a slider 16. The end of the slider 16 away from the slide groove 15 is fixedly connected to the limiting cone 6. Through the setting of the slide groove 15 and the slider 16, the limiting cone 6 can be limited and guided to move.

[0025] The principle of this embodiment is:

[0026] When in use, by setting the first protective plate 1, the second protective plate 2 and the extension plate 3, when the extension plate 3 is unfolded, the protection area can be adjusted to expand the protection area. When the extension plate 3 is closed into the first protective plate 1 and the second protective plate 2, the shielding ability of the first protective plate 1 and the second protective plate 2 is increased, and the protection force is improved. Then the turning handle 11 is rotated to drive the transmission rod 10 to rotate, the transmission rod 10 drives the active gear 9 to rotate, the active gear 9 drives the driven gear 8 to rotate, and the driven gear 8 drives the threaded rod 5 to rotate. The threaded rod 5 drives the limiting cone 6 embedded with the threaded tube 7 to move downward, so that the limiting cone 6 is inserted downward into the soil for fixation, which can play a good fixing effect and can facilitate the user to fix the protection structure, thereby solving the problem that the protection area of ​​the existing protection structure against soil erosion is fixed and cannot be adjusted, and the shielding strength of the protection cannot be adjusted, thereby affecting the protection effect.
