Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a slope protection device for water conservancy projects. Background Technology

[0002] In water conservancy projects, slope stability is directly related to the safety and durability of the project. Traditional slope protection methods have many drawbacks. For example, simple stone-built slope protection is easily loosened by water erosion, which greatly reduces the effectiveness of slope protection; although concrete slope protection is strong, it lacks ecological functions and is not conducive to the natural growth of vegetation and the maintenance of ecological balance.

[0003] Currently, some slope protection nets on the market have relatively simple functions, and most of them can only provide basic reinforcement. They are prone to loosening under long-term water erosion. In addition, although vegetation slope protection can stabilize the soil to a certain extent, it lacks effective drainage measures. When encountering heavy rainfall, water accumulation inside the slope may lead to problems such as soil softening and landslides. Utility Model Content

[0004] The purpose of this invention is to provide a slope protection device for water conservancy projects, which solves the problems of the single function of the existing slope protection net and the easy loosening of the slope protection soil layer under long-term rainwater erosion.

[0005] The technical solution adopted by this utility model is a slope protection device for water conservancy projects, including a lower fixed frame and a pair of upper fixed frames that are connected to each other. Several sets of reinforcing nets are installed on the lower fixed frame and the pair of upper fixed frames respectively. The upper and lower ends of the lower fixed frame are respectively movably connected to a first fixed plate and a second fixed plate. Several sets of fixing components for fixed connection with the slope are provided at the bottom of the lower fixed frame.

[0006] Multiple drain pipes are distributed between the upper and lower fixed frames. One end of the drain pipe is connected to the groove on the first fixed plate through a flexible hose, and the other end is connected to the water outlet pipe installed in the second fixed plate through a flexible hose.

[0007] The present invention is further characterized in that,

[0008] The fixing component includes an adjusting rod that is rotatably connected to the lower fixing frame, and the upper surface of the adjusting rod has an adjusting groove with a rectangular cross-section.

[0009] The bottom of the adjusting rod is connected to a drive rod, and a fixed rod is set at the bottom of the lower fixed frame relative to the adjusting rod. The fixed rod has a hollow structure, and the drive rod is located inside the fixed rod. The bottom of the drive rod is connected to an umbrella-shaped component. Rotating the adjusting rod drives the drive rod to rise and fall, thus opening and closing the umbrella-shaped component.

[0010] The lower end of the adjusting rod passes through the inside of the fixed rod, and the lower end of the adjusting rod is threadedly connected to the drive rod;

[0011] A limiting frame is also fixedly connected to the inside of the fixed rod. The lower end of the drive rod passes through the inside of the limiting frame, and the lower end of the drive rod has a rectangular cross-section. The inside of the limiting frame is a rectangular opening that cooperates with the lower end of the drive rod.

[0012] The umbrella-shaped assembly includes a base, which is connected to the inner wall of the fixed rod. A support rod is connected to the top of the base, and the upper end of the support rod passes through the drive rod.

[0013] Several reinforcing struts are movably connected to the base. These reinforcing struts are distributed along the circumference of the base, and the fixed struts have notches relative to the positions of the reinforcing struts.

[0014] A circular sleeve is movably connected to the support rod. The circular sleeve is connected to the bottom end of the drive rod. A connecting rod is movably connected to the lower end of the circular sleeve. The other end of the connecting rod is movably connected to the reinforcing support rod.

[0015] A limit ring is also fixedly connected to the support rod, and the limit ring is located below the circular sleeve.

[0016] Planting troughs are installed on the reinforcement net, and hooks are installed inside the planting troughs.

[0017] The upper fixed frame is movably connected to both sides of the lower fixed frame, and fixing bolts for connecting the upper fixed frame and the lower fixed frame are provided between the upper fixed frames.

[0018] Anchor bolts are also installed on the first and second fixing plates. One end of the anchor bolt is connected to a handwheel. Turning the handwheel causes the anchor bolt to penetrate the fixing plate and insert into the slope.

[0019] The beneficial effects of this utility model are:

[0020] (1) The water conservancy engineering slope protection device of this utility model sets up an upper fixed frame and a lower fixed frame, and installs a reinforcing net on both fixed frames. The double-layer reinforcing net can effectively reduce the risk of soil erosion caused by rainwater scouring. At the same time, this utility model also sets up a drainage pipe between the upper and lower reinforcing nets. Rainwater falling on the top of the slope gathers in the groove and is drained through the drainage pipe to the outlet pipe for discharge, avoiding rainwater scouring of the slope soil from the top of the slope and greatly reducing the problems of slope soil softening and landslides.

[0021] (2) The slope protection device for water conservancy projects of this utility model has several fixing components at the bottom of the lower fixing frame. The fixing components are equipped with an umbrella-shaped structure. By rotating the adjusting rod, the driving rod is driven to move down. Since the driving rod is connected to the circular sleeve, the driving rod moves down and drives the circular sleeve to move down at the same time, pressing the umbrella-shaped component to open. The reinforcing support rod of the umbrella-shaped component cuts into the soil through the notch, which increases the connection stability between the lower fixing frame and the slope.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] This utility model relates to a slope protection device for water conservancy projects, such as... Figure 1 As shown, the system includes a lower fixing frame 2 and a pair of upper fixing frames 3 connected to each other. Several sets of reinforcing nets 4 are installed on the lower fixing frame 2 and the pair of upper fixing frames 3 respectively. Planting troughs 5 are installed on the reinforcing nets 4 of the upper fixing frames 3, and hooks 6 are provided in the planting troughs 5. Nutrients for vegetation growth can be provided on the hooks 6.

[0030] The lower fixing frame 2 is movably connected to the upper and lower ends of the first fixing plate 7 and the second fixing plate 10 respectively, and the bottom of the lower fixing frame 2 is provided with several sets of fixing components 14 for fixed connection with the slope 1.

[0031] Multiple drain pipes 9 are distributed between the upper fixed frame 3 and the lower fixed frame 2. One end of the drain pipe 9 is connected to the groove 8 on the first fixed plate 7 through a flexible hose, and the other end is connected to the water outlet pipe 13 provided in the second fixed plate 10 through a flexible hose.

[0032] Furthermore, the upper fixed frame 3 is movably connected to both sides of the lower fixed frame 2, and fixing bolts for connecting the upper fixed frame 3 and the lower fixed frame 2 are provided between the upper fixed frames 3.

[0033] In use, the lower fixing frame 2 is attached to the slope 1, the fixing component 14 is inserted into the soil of the slope 1, the level of the lower fixing frame 2 is adjusted, and then the first fixing plate 7 and the second fixing plate 10 are rotated to fit with the top and bottom of the slope. After the first fixing plate 7 and the second fixing plate 10 are fixed to the slope, the upper fixing frame 3 is rotated until the upper fixing frame 3 and the lower fixing frame 2 are parallel to each other. Soil is filled into the position where the reinforcement net 4 is set, and vegetation is planted in the planting trough 5 and the soil outside the planting trough 5. Because the soil filling height in the planting trough 5 is relatively high, small and medium-sized vegetation can be planted. The roots of small and medium-sized vegetation grow into the deeper soil, which can better improve the protection effect of the slope.

[0034] Example 2

[0035] This utility model relates to a slope protection device for water conservancy projects, such as... Figure 1 As shown, the system includes a lower fixing frame 2 and a pair of upper fixing frames 3 connected to each other. Several sets of reinforcing nets 4 are installed on the lower fixing frame 2 and the pair of upper fixing frames 3 respectively. Planting troughs 5 are installed on the reinforcing nets 4 of the upper fixing frames 3, and hooks 6 are provided in the planting troughs 5. Nutrients for vegetation growth can be provided on the hooks 6.

[0036] The lower fixing frame 2 is movably connected to the upper and lower ends of the first fixing plate 7 and the second fixing plate 10 respectively, and the bottom of the lower fixing frame 2 is provided with several sets of fixing components 14 for fixed connection with the slope 1.

[0037] Multiple drain pipes 9 are distributed between the upper fixed frame 3 and the lower fixed frame 2. One end of the drain pipe 9 is connected to the groove 8 on the first fixed plate 7 through a flexible hose, and the other end is connected to the water outlet pipe 13 provided in the second fixed plate 10 through a flexible hose.

[0038] like Figure 2 As shown, anchor rods 12 are also provided on the first fixing plate 7 and the second fixing plate 10. One end of the anchor rod 12 is connected to a handwheel 11. Rotating the handwheel 11 causes the anchor rod 12 to penetrate the fixing plate and insert into the slope 1.

[0039] When in use, first place the lower fixing frame 2 at the predetermined position at the bottom of the slope 1, forcefully insert the fixing component 14 at the lower end of the lower fixing frame 2 into the ground to initially fix the lower fixing frame 2 and keep it stable. Then, according to the actual slope of the slope, rotate the two upper fixing frames 3 and adjust the angle between them and the lower fixing frame 2 until they fit the slope of the slope. Then tighten the fixing bolt at the center of the upper fixing frame 3 to lock the relative position of the upper and lower fixing frames.

[0040] Then, rotate the first fixing plate 7 and the second fixing plate 10 to a suitable angle so that they are in full contact with the ground. By turning the handwheel 11, drive the anchor rod 12 to slowly screw into the ground until the first fixing plate 7 and the second fixing plate 10 are firmly fixed to the ground, further stabilizing the lower fixing frame 2.

[0041] When it rains, the water will enter the drain pipe 9 through the groove 8. The water will then flow through the drain pipe 9 and the hose into the outlet pipe 13 inside the second fixing plate 10, and finally be discharged to the designated area.

[0042] Suitable vegetation can be planted in the planting trough 5 of the reinforcement net 4, and nutrients for vegetation growth can be placed on the hook 6 to increase the survival rate. During the growth process, the roots of the vegetation penetrate deep into the slope soil, playing a role in soil stabilization and slope protection. The hook 6 in the planting trough 5 can be used to hang auxiliary facilities such as protective nets as needed.

[0043] Furthermore, when the reinforcing net 4 of the upper fixing frame 3 is damaged, only the upper fixing frame 3 needs to be opened to replace the upper reinforcing net 4, without changing the reinforcing net on the lower fixing frame 2, thus maintaining the stability of the soil.

[0044] Example 3

[0045] This embodiment is based on the above embodiment 2, such as Figure 3 As shown, the fixing component of the water conservancy engineering slope protection device of this utility model includes an adjusting rod 15 that is rotatably connected to the lower fixing frame 2. The upper surface of the adjusting rod 15 is reserved with an adjusting groove with a rectangular cross-section.

[0046] A drive rod 17 is connected to the bottom of the adjusting rod 15, and a fixed rod 16 is positioned at the bottom of the lower fixed frame 2 relative to the adjusting rod 15. The fixed rod 16 has a hollow structure, and the drive rod 17 is located inside the fixed rod 16. An umbrella-shaped component 20 is connected to the bottom of the drive rod 17. Rotating the adjusting rod 15 causes the drive rod 17 to rise and fall, thus opening and closing the umbrella-shaped component 20. A notch 19 is also provided on the fixed rod 16 relative to the umbrella-shaped component 20.

[0047] Example 4

[0048] Based on Embodiment 3 above, in this embodiment, the lower end of the adjusting rod 15 in the water conservancy engineering slope protection device of this utility model passes through the inside of the fixed rod 16, and the lower end of the adjusting rod 15 is threadedly connected to the driving rod 17.

[0049] A limiting frame 18 is also fixedly connected to the inner side of the fixed rod 16. The lower end of the drive rod 17 passes through the interior of the limiting frame 18, and the lower end of the drive rod 17 has a rectangular cross-section. The inner side of the limiting frame 18 has a rectangular opening that mates with the lower end of the drive rod 17. This ensures that the drive rod 17 will not rotate with the adjusting rod 15, thus ensuring the stability of the drive rod 17 during adjustment.

[0050] When the fixing component 14 is in use, the fixing rod 16 is inserted into the soil, and the lower fixing frame 2 is laid flat in the predetermined position. Then, the adjusting rod 15 is rotated through the adjusting groove using an external tool. Since the adjusting rod 15 and the driving rod 17 are connected by a thread, the driving rod 17 can be raised and lowered within the fixing rod 16. The raising and lowering of the driving rod 17 drives the opening and closing of the umbrella-shaped component 20. The umbrella-shaped component 20 passes through the notch 19 on the fixing rod 16 and enters the soil. The umbrella-shaped component 20 increases the stability of the fixing rod 16 inserted into the soil, thereby ensuring the stability of the lower fixing frame 2.

[0051] Example 5

[0052] This embodiment is based on embodiment 4 above, such as Figure 4 As shown, the umbrella-shaped component 20 of the water conservancy engineering slope protection device of this utility model includes a base 22, which is connected to the inner wall of the fixing rod 16. A support rod 21 is connected to the top of the base 22, and the upper end of the support rod 21 passes through the drive rod 17.

[0053] Several reinforcing support rods 26 are movably connected to the base 22. The reinforcing support rods 26 are distributed along the circumference of the base 22. The notch 19 is opened at the position of the fixed rod 16 relative to the reinforcing support rod 26.

[0054] A circular sleeve 23 is movably connected to the support rod 21. The circular sleeve 23 is connected to the bottom end of the drive rod 17. A connecting rod 24 is movably connected to the lower end of the circular sleeve 23. The other end of the connecting rod 24 is movably connected to the reinforcing support rod 26.

[0055] When the adjusting rod 15 rotates and drives the driving rod 17 to move downward, it drives the annular sleeve 23 to move downward synchronously. The annular sleeve 23 slides relative to the support rod 21. Since the bottom of the annular sleeve 23 is movably connected to the connecting rod 24, when the annular sleeve 23 moves downward, it will drive one end of the connecting rod 24 to move downward synchronously. At this time, the other end of the connecting rod 24 pushes the reinforcing support rod 26 to rotate relative to the base 22, achieving the "opening umbrella" effect. At this time, the reinforcing support rod 26 passes through the notch 19 and cuts into the soil, effectively increasing the force-bearing area between the fixed rod 16 and the soil, and improving the connection stability of the lower fixed frame 2.

[0056] When it is necessary to remove the fixing rod 16 from the soil, simply rotate the adjusting rod 15 in the opposite direction to move the driving rod 17 upward, thus achieving the "umbrella closing" effect.

[0057] Furthermore, in order to make it easier for the reinforcing strut 26 to cut into the soil, the side of the reinforcing strut 26 opposite to the notch 19 is blade-shaped, so that the reinforcing strut 26 can cut into the soil more easily when the umbrella-shaped component 20 "opens the umbrella".

[0058] Example 6

[0059] Based on Embodiment 5 above, in this embodiment, a limiting ring 25 is also fixedly connected to the support rod 21 of the water conservancy engineering slope protection device of this utility model, and the limiting ring 25 is located below the circular sleeve 23.

[0060] When the bottom of the annular sleeve 23 is in contact with the limiting ring 25, the drive rod 17 stops moving downward, and at this time the connecting rod 24 and the reinforcing support rod 26 are extended to their maximum extent.
