Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically a slope reinforcement device and method for water conservancy projects. Background Technology

[0002] This slope reinforcement device for water conservancy projects is specifically designed for slope protection and restoration in various water conservancy projects, suitable for use in multiple slope scenarios such as rivers, reservoirs, and embankments. It boasts strong overall adaptability, capable of handling slope conditions with varying gradients and geological features. It effectively resists rainwater erosion, water flow erosion, and soil slippage, reducing the risk of slope landslides and collapses at the source. The device is easy to install, has good overall stability and a long service life, and also possesses excellent drainage performance, effectively diverting surface water from slopes and preventing water infiltration from damaging the slope structure. Balancing engineering safety and ecological protection needs, it minimizes construction disturbance and facilitates convenient maintenance, ensuring long-term operational safety of water conservancy slopes. It is suitable for slope reinforcement, renovation, and new protection projects in various water conservancy projects. Existing slope reinforcement devices for water conservancy projects generally suffer from single-function limitations and insufficient protective coordination. In the event of sudden rainstorms or heavy rainfall, they cannot be quickly deployed to lay rainproof tarpaulins, nor can they promptly seal and protect the slope. This can easily lead to large-scale rainwater infiltration, slope erosion, and soil softening, exacerbating the risk of landslides and collapses. Furthermore, they lack emergency rainproof structures that can be quickly deployed, temporarily sealed, and used immediately after laying, making it difficult to meet the emergency protection needs of slopes under rainstorm conditions. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a slope reinforcement device and method for water conservancy projects, which effectively solves the problem that the existing water conservancy slope reinforcement devices cannot quickly lay raincoats and are prone to slope seepage and instability when encountering rainstorms.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a slope reinforcement device for water conservancy projects, comprising a slope top plate with connecting holes at its four corners for fixing to the foundation at the top of the slope. Two longitudinal strips are symmetrically fixed to the front end of the slope top plate, and a reinforcement frame is fixed between the bottom of the longitudinal strips. Multiple anchor rods are threaded through the reinforcement frame, and the top of the anchor rods is equipped with a fastening head that can be inserted into the slope to achieve overall anchoring. A controller is installed on the upper surface of the slope top plate for controlling the start / stop, direction, and running speed of the servo motor.

[0005] A roller is installed between the upper ends of the two longitudinal strips, and a raincoat is wrapped around the outside of the roller. Baffles are fixed to both ends of the raincoat on the surface of the roller to prevent it from shifting. A movable beam is installed below the roller, and an equipment box and protective cover are fixed to the bottom of the movable beam. Support legs are fixed to the lower ends of the longitudinal strips for slope support; a placement edge is fixed to the upper inner side of the longitudinal strips to support the raincoat.

[0006] Preferably, a servo motor is fixed inside the protective cover, and a transmission assembly is provided at the output end of the servo motor, which is connected to the moving beam. The transmission assembly includes a driving bevel gear, a driven bevel gear, a shaft, a shaft seat, a gear column, a gear rail, and a positioning seat. The driving bevel gear is installed at the output end of the servo motor and meshes with the driven bevel gear. The driven bevel gear is coaxially fixed with the shaft, and both ends of the shaft extend out of the equipment box and connect to the gear column. The gear column meshes with the gear rail fixed on the longitudinal strip. The shaft is rotatably positioned with the equipment box and the moving beam through the shaft seat, and the gear column is rotatably positioned with the moving beam through the positioning seat. Sliding strips are fixed at both ends of the equipment box, and a sliding groove is opened on the inner side of the gear rail. The sliding strips slide with the sliding groove to ensure that the moving beam runs smoothly without deviation.

[0007] Preferably, an installation groove is formed on the inner side of the longitudinal strip, and support arms are fixed on both sides of the rear end of the moving beam. The support arms extend into the installation groove and are connected to a rotating seat. The rotating seat is rotatably connected to both ends of the roll. A guide block is fixed to the bottom of the rotating seat, and a guide groove is formed at the bottom of the installation groove. The guide block and the guide groove slide together to improve the movement accuracy of the roll. First gears are fixed to both ends of the roll. The first gears mesh with a first rack fixed to the bottom of the installation groove, so that the roll rotates synchronously when the moving beam moves downward, realizing the raincoat automatically unfolds at a uniform speed.

[0008] Preferably, multiple sets of clamping components are provided on the inner side of the longitudinal strip. Each clamping component includes a clamping frame, a slot, a threaded sleeve, a lead screw, a positioning frame, a second gear, and a rotating seat. The clamping frame is movably inserted into the slot, with its upper end bent inwards. A threaded sleeve is fixed to the bottom of the clamping frame, and the threaded sleeve is threadedly connected to the lead screw. The lead screw is rotated and positioned with the longitudinal strip via the positioning frame, and a second gear is fixed to its bottom. The second gear is positioned via the rotating seat, and a second rack is fixed to the lower side of the moving beam, meshing with the second gear. When the moving beam descends, it drives the second rack to rotate, causing the second gear and lead screw to rotate, thus moving the threaded sleeve and clamping frame downwards and pressing the raincoat firmly against the placement edge to prevent wind blowing, slippage, and leakage.

[0009] When the servo motor is running, it drives the moving beam to move along the longitudinal strip towards the bottom of the slope through the transmission component. The roller rotates synchronously under the cooperation of gear and rack to unfold the raincoat, achieving rapid full coverage of the slope. The pressing component moves synchronously with the moving beam, pressing the unfolded raincoat section by section to ensure stable and reliable protection under heavy rain conditions.

[0010] The present invention also provides a method for slope reinforcement in water conservancy projects, based on the above-mentioned device, and the steps are as follows: On-site installation and positioning: Fix the top plate to the top surface of the slope and anchor it to the foundation using the connecting holes; fit the reinforcement frame against the slope surface, drive the anchor rod through the reinforcement frame into the slope soil, and lock the fastening head to complete the device fixation; support the outriggers at the toe of the slope to ensure overall stability.

[0011] Control system self-test: The controller performs no-load tests on the servo motor, transmission mechanism, winding mechanism, and clamping mechanism to confirm smooth operation, normal signals, and accurate limit switches.

[0012] Emergency deployment during heavy rain: When a rain warning is received or a sudden heavy rain occurs, the controller starts the servo motor to rotate forward, and the transmission component drives the moving beam to descend at a constant speed; the roller rotates synchronously under the action of the first gear and the first rack, and the raincoat is evenly deployed and covers the slope.

[0013] Synchronous pressing and fixing: During the downward movement of the moving beam, the second rack drives each second gear to rotate in sequence, which in turn drives the lead screw to rotate, causing the lead sleeve and the pressure frame to move down, pressing the edge of the raincoat onto the placement edge, thus achieving simultaneous laying and pressing and full-process stability.

[0014] Protection ends and is retracted: After the rainstorm ends, the controller controls the servo motor to reverse, the moving beam moves upward to reset, and the roller rotates in the opposite direction to retract the raincoat; the second rack drives the clamping components to loosen in sequence, the raincoat is retracted into the roller, and the device returns to standby state.

[0015] Compared with the prior art, the beneficial effects of the present invention are: It enables raincoats to automatically and quickly deploy during heavy rain without manual operation, providing rapid response, complete coverage, and timely prevention of rainwater infiltration; The spreading and compaction are synchronized, spreading and compacting at the same time, so that the raincoat does not slip, lift up or leak, greatly improving the protective stability; It integrates slope anchoring and reinforcement, emergency rain protection, and automatic control, with high structural integration and strong adaptability, and is suitable for various types of water conservancy slopes; It is reliable in operation, simple to operate, and convenient to maintain, significantly reducing the risk of slope instability, landslides, and collapses induced by rainstorms, with outstanding safety benefits.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example 1, by Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The invention comprises a slope top plate 1, longitudinal strips 2, a reinforcing frame 3, a controller 4, a roller 5, a raincoat 6, a moving beam 7, an equipment box 8, a protective cover 9, a servo motor 10, anchor rods 12, a transmission assembly, and a clamping assembly. The slope top plate 1 is fixed to the top of the slope, with connecting holes 40 at the four corners for fixing to the foundation at the top of the slope. Two longitudinal strips 2 are symmetrically fixed to the front end of the slope top plate 1 and arranged along the slope surface. A reinforcing frame 3 is fixed between the bottom of the two longitudinal strips 2. The reinforcing frame 3 fits against the slope surface to form a support frame, and multiple anchor rods 12 are evenly inserted on it. The top of the anchor rod 12 is provided with a fastening head 38, which can be inserted into the slope soil to achieve overall anchoring. The lower end of the longitudinal strip 2 is fixed with a support leg 39 to support the slope foot, and the upper inner side is fixed with a support edge 28 to support the edge of the raincoat 6.

[0020] A roller 5 is rotatably mounted between the upper ends of the two longitudinal strips 2. A raincoat 6 is wrapped around the outside of the roller 5 and baffles 21 are provided at both ends to prevent deviation. A movable beam 7 is provided below the roller 5. The bottom of the movable beam 7 is fixed with an equipment box 8 and a protective cover 9. A servo motor 10 is installed inside the protective cover 9. The output end of the servo motor 10 is connected to a transmission component.

[0021] Depend on Figure 4 , Figure 6 as well as Figure 7 The transmission assembly includes a driving bevel gear 11, a driven bevel gear 13, a shaft 14, a shaft seat 15, a gear column 16, a gear rail 17, and a positioning seat 18. The driving bevel gear 11 is fixed to the output end of the servo motor 10 and meshes with the driven bevel gear 13. The driven bevel gear 13 is coaxially fixed to the shaft 14. Both ends of the shaft 14 pass through the equipment box 8 and fix the gear column 16. The gear column 16 meshes with the gear rail 17 fixed on the longitudinal bar 2. The gear column 16 is rotatably connected to the moving beam 7 through the positioning seat 18. The shaft 14 is rotatably positioned with the equipment box 8 and the moving beam 7 through four shaft seats 15.

[0022] Sliding strips 19 are fixed at both ends of the equipment box 8. A sliding groove 20 is opened on the inner side of the toothed rail 17. The sliding strips 19 are embedded in the sliding groove 20 to slide and achieve guidance and limit, ensuring that the moving beam 7 runs smoothly without deviation. An installation groove 29 is opened on the inner side of the longitudinal strip 2. Support arms 25 are fixed on both sides of the rear end of the moving beam 7. The support arms 25 extend into the installation groove 29 and fix the rotating seat 22. The rotating seat 22 is rotatably connected to both ends of the roller 5. A guide block 26 is fixed at the bottom of the rotating seat 22. A guide groove 27 is opened at the bottom of the installation groove 29. The guide block 26 is embedded in the guide groove 27 to slide and improve the movement stability.

[0023] The first gear 23 is fixed at both ends of the roll 5. The first gear 23 meshes with the first rack 24 fixed at the bottom of the mounting groove 29. When the moving beam 7 moves, the first gear 23 rolls along the first rack 24, so that the roll 5 rotates synchronously, so that the raincoat 6 can be unfolded flat, at a uniform speed and without pulling.

[0024] Depend on Figure 5 and Figure 8As shown, multiple sets of clamping components are arranged inside the longitudinal strip 2. The clamping components include a clamping frame 31, a slot 32, a threaded sleeve 33, a lead screw 34, a positioning frame 35, a second gear 36, and a rotating seat 37. The clamping frame 31 is movably inserted into the slot 32 with its upper end bent inward. The threaded sleeve 33 is fixed to the bottom of the clamping frame 31 and is threadedly connected to the lead screw 34. The top of the lead screw 34 is rotated and positioned with the longitudinal strip 2 by the positioning frame 35, and the bottom is fixed with the second gear 36 and positioned by the rotating seat 37. A second rack 30 is fixed to the lower side of the moving beam 7. The second rack 30 meshes with the second gear 36. When the moving beam 7 moves downward, the second rack 30 drives the second gear 36 to rotate, which drives the lead screw 34 to rotate, causing the threaded sleeve 33 and the clamping frame 31 to move downward, pressing the edge of the raincoat 6 against the placement edge 28. A controller 4 is installed on the slope plate 1 to control the start, stop, forward and reverse rotation, and running speed of the servo motor 10, realizing fully automatic control.

[0025] The slope reinforcement method for hydraulic engineering adopted in this invention includes the following steps: Step 1: On-site installation. Fix the top plate 1 to the top of the slope and anchor it to the foundation through the connecting hole 40. Fit the reinforcement frame 3 to the slope surface. Drive the anchor rod 12 through the reinforcement frame 3 into the slope soil and lock the fastening head 38. Support the outrigger 39 at the foot of the slope to complete the device fixation. Step 2: System self-test. The servo motor 10 is started by the controller 4 for no-load test to check whether the transmission components, the rotation of the roller 5, and the operation of the clamping components are normal. Step 3, emergency deployment: When the rainstorm arrives, the controller 4 starts the servo motor 10 to rotate forward, and drives the moving beam 7 to move down along the longitudinal bar 2 through the transmission component. The roller 5 rotates synchronously under the action of the first gear 23 and the first rack 24, and automatically unfolds the raincoat 6 to cover the slope. Step 4, synchronous pressing: the moving beam 7 moves downward, driving the second rack 30 to drive the second gear 36 and the lead screw 34 to rotate, and the screw sleeve 33 drives the pressure frame 31 to move downward, pressing the raincoat 6 onto the placement edge 28; Step 5, protection maintenance and recovery: After the rainstorm ends, servo motor 10 reverses, moving beam 7 moves upward, roller 5 rotates to recover raincoat 6, and clamping components are released synchronously to complete the reset.

[0026] After the servo motor 10 starts, it drives the active bevel gear 11 and the driven bevel gear 13 to rotate. The shaft 14 and the gear column 16 rotate synchronously. The gear column 16 rolls along the gear rail 17 to push the moving beam 7 downward. The moving beam 7 drives the roller 5 to move downward. The first gear 23 and the first rack 24 cooperate to make the roller 5 rotate and unfold the raincoat 6. At the same time, the second rack 30 at the bottom of the moving beam 7 drives the second gear 36 of each pressing component to rotate in sequence. The lead screw 34 rotates and drives the lead sleeve 33 and the pressure frame 31 to move downward, pressing the edge of the raincoat 6 section by section onto the placement edge 28. After the raincoat 6 completely covers the slope, it can effectively block rainwater infiltration, prevent slope erosion and soil softening, and ensure that the slope is stable and does not seep or landslide under heavy rain conditions.

[0027] After the rain, the servo motor 10 reverses, the moving beam 7 moves upward to reset, the roller 5 retracts the raincoat 6, the clamping components are released synchronously, and the device returns to standby mode. With the anchoring effect of the reinforcement frame 3 and the anchor rod 12, long-term reinforcement and emergency rain protection are integrated.
