Description

Technical Field

[0001] This invention belongs to the field of geotechnical engineering and ecological restoration technology, specifically relating to a rock slope protection device in water-scarce areas. Background Technology

[0002] In mountainous urban construction, road administration, mining, and other engineering activities, rock slopes are inevitably generated. Managing rock slopes in water-scarce areas presents numerous challenges. On the one hand, rock slopes themselves have poor stability and are prone to landslides and collapses under the influence of natural factors such as weathering, rainfall, and earthquakes, threatening the safety of surrounding buildings, roads, and people. On the other hand, water-scarce areas lack water resources, making plant growth difficult, and traditional slope greening methods are ineffective, resulting in a deteriorated slope ecological environment and severe soil erosion.

[0003] Common methods for supporting rock slopes include retaining walls and anti-slide piles. While these methods can improve slope stability to some extent, they suffer from high costs, complex construction, and do not consider slope greening and ecological restoration. Traditional slope greening methods, such as hydroseeding, struggle to achieve the desired greening and ecological restoration effects in water-scarce areas due to insufficient water. Therefore, developing a comprehensive management method that can effectively improve the stability of rock slopes in water-scarce areas while also achieving slope greening and ecological restoration is of significant practical importance. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies and proposes a protection device for rock slopes in water-scarce areas. Without affecting the anchor structure and slope ecology, it effectively realizes the integrated functions of slope stability support, automatic rainwater collection and intelligent irrigation during drought. Through a purely mechanical structure, it achieves reliable fixation of seed storage bags and adaptive water supply, improves the reliability of ecological restoration of rock slopes in water-scarce areas, reduces the later maintenance cost, and solves the current problems of difficulty in water storage, difficulty in plant growth, and difficulty in fixing seed storage bags on the slope.

[0010] Furthermore, the water collection mechanism also includes a three-way pipe and a sealing plug; an inlet is provided on the top plate of the water storage tank, and a three-way pipe is fixedly installed at the inlet. The first and second interfaces of the three-way pipe are kept horizontal, and the third interface of the three-way pipe extends vertically downward through the inlet into the interior of the water storage tank. The outlet of the collection pipe is fixedly connected to the first interface of the three-way pipe, and a sealing plug is slidably inserted into the second interface of the three-way pipe.

[0011] Furthermore, the water collection mechanism also includes a float and a float support. A first clearance groove is provided on the side wall of the second interface of the tee pipe.

[0012] Furthermore, the automatic irrigation mechanism also includes a water-drawing pipe, which is fixedly installed on the inner wall of the water storage tank. The water-drawing cone is slidably installed vertically inside the water-drawing pipe, and a second groove is provided on the outer wall of the water-drawing cone. A second clearance groove is provided on the side wall of the water storage tank, and a third clearance groove is provided on the side wall of the water-drawing pipe.

[0016] The beneficial effects of this invention compared to the prior art are as follows: (1) By setting up a gripping and fixing mechanism, the fixing claws are tightly engaged with the mesh of the winch net, and combined with the limiting mechanism of the ratchet, adjustable protrusion, and fixed protrusion, the water collection mechanism and automatic irrigation mechanism are reliably fixed. The gripping and fixing mechanism does not rely on easily aging components such as springs, effectively avoiding the problem of fixing failure caused by elastic decay in the unmaintained outdoor environment, and significantly improving the long-term stability of the device under harsh conditions in water-scarce areas.

[0017] (2) The water collection mechanism efficiently collects rainwater and dew through the arc-shaped collection pipe and collection plate. With the help of the automatic control mechanism of the float and the sealing plug, the water inlet of the water tank is automatically closed when the water level in the storage tank reaches a certain height to prevent the water from being too full and affecting the stability of the anchor. This design not only realizes the intelligent collection and storage of water resources, but also takes into account the aesthetics of the slope treatment process. The collection plate can be designed in the shape of a leaf and sprayed with green to blend naturally with the environment.

[0018] (3) The automatic irrigation mechanism realizes the automatic triggering of the one-way ball valve to open when the seed storage bag is not moist enough through the gravity balance mechanism between the planting platform and the water-drawing cone. The water in the water storage tank is transported to the planting platform through the capillary water suction tube to supply the plant growth. After the seed storage bag absorbs water and increases in weight, the water supply is automatically shut off to avoid root rot. The automatic irrigation mechanism is mechanically driven throughout the process and does not rely on electronic sensors. It effectively overcomes the problem of sensor failure in the harsh environment of water-scarce areas and realizes low-cost and high-reliability automatic irrigation and ecological restoration.

Detailed Implementation

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0021] like Figure 1 As shown in Figure 10, this invention provides a rock slope protection device for water-scarce areas, including a grid mesh 34, a cable net 35, an anchor bolt 1, a gripping and fixing mechanism 2, a water collection mechanism 3, and an automatic irrigation mechanism 4. The grid mesh 34 is laid on the slope surface, and the cable net 35 covers the grid mesh 34. The grid mesh 34 and the cable net 35 are fixed to the slope surface by the anchor bolt 1. The gripping and fixing mechanism 2 is snapped and fixed at the tail end of the anchor bolt 1. The gripping and fixing mechanism 2 includes a snap-fit ​​sleeve 5, an operating platform 6, and a fixing bracket 7. The snap-fit ​​sleeve 5 is snapped and fixed to the outside of the tail end of the anchor bolt 1. The operating platform 6 is fixedly installed on the outside of the snap-fit ​​sleeve 5, and a ring of one-way rotating fixing bracket 7 is provided on the operating platform 6. The water collection mechanism 3 includes a water storage tank 15 and a collection pipe 19. A collection plate 21 and a water storage tank 15 are fixedly installed at the tail end of the locking sleeve 5. A collection pipe 19 is installed on the water storage tank 15, and a collection plate 21 is fixedly installed at one end of the outer side of the collection pipe 19. The automatic irrigation mechanism includes a planting platform 23, a lifting bracket 24, a capillary suction pipe 30, a water-drawing cone 28, and a one-way ball valve 22. A height-adjustable planting platform 23 is installed on the outer wall of the water storage tank 15, and a height-adjustable water-drawing cone 28 is installed on the inner wall of the water storage tank 15. The two ends of the capillary suction pipe 30 are fixedly connected to the planting platform 23 and the water-drawing cone 28, respectively. A lifting bracket 24 is rotatably installed on the side wall of the water storage tank 15, and the two ends of the lifting bracket 24 are connected to the planting platform 23 and the water-drawing cone 28, respectively. The one-way ball valve 22 is installed at the lower end of the water-drawing cone 28.

[0022] The engaging sleeve 5 is a cylindrical structure with openings at both ends, and the operating table 6 is a cuboid structure. The operating table 6 is fixedly fitted onto the outer side of the front opening of the engaging sleeve 5. A bracket mounting groove 9 is provided on each of the outer surfaces of the operating table 6, and the bracket mounting groove 9 is connected to the front surface of the operating table 6. A fixed bracket 7 is rotatably mounted inside each bracket mounting groove 9. The fixed bracket 7 includes a mounting base and a fixing claw 13. The mounting base is fixedly mounted inside the bracket mounting groove 9, and the mounting base has a fixing claw rotation groove. One end of the fixing claw 13 is rotatably mounted inside the fixing claw rotation groove of the mounting base, and the initial position of the fixing claw 13 is limited by the inner wall of the fixing claw rotation groove.

[0023] A one-way rotation assembly is provided between the mounting base and the fixed claw 13. This assembly includes a ratchet 8, an adjustable protrusion 11, and a fixed protrusion 12. A circular ratchet rotation groove 10 is provided on the mounting base. A ratchet 8 is rotatably positioned at the center of the ratchet rotation groove 10. The ratchet 8 is fixedly connected to the corresponding end of the fixed claw 13 via a rotating shaft, which is rotatably located inside the mounting base. When the ratchet 8 rotates, it drives the fixed claw 13 to rotate synchronously via the rotating shaft. A ring of fixed protrusions 12 is fixedly arranged on the inner cylindrical surface of the ratchet rotation groove 10. A ring of adjustable protrusions 11 is also rotatably arranged on the inner cylindrical surface of the ratchet rotation groove 10. The number of fixed protrusions 12 and adjustable protrusions 11 is equal, and they are all arranged in a circular array around the axis of the ratchet rotation groove 10. The adjustable protrusions 11 and fixed protrusions 12 are staggered. The fixed protrusions 12 limit the movement of one side of the adjustable protrusion 11, ensuring that the adjustable protrusion 11 can only rotate in one direction. A torsion spring is provided between the adjustable protrusion 11 and the inner cylindrical surface of the ratchet rotation groove 10, so that the adjustable protrusion 11 can be restored to its original position after rotation.

[0024] When ratchet 8 rotates forward, it actuates adjustable protrusion 11, causing it to rotate. This allows ratchet 8 to pass through the rotated protrusion 11, thus achieving forward rotation. After passing through protrusion 11, it returns to its original position under the restoring force of the torsion spring. When ratchet 8 begins to rotate in the reverse direction, fixed protrusion 12 limits its rotation, preventing reverse rotation. Therefore, ratchet 8 can only rotate in one direction, thus causing fixed pawl 13 to rotate only in one direction.

[0025] The control panel 6 is provided with four insertion holes, and a detachable insert 14 is inserted into each of the four insertion holes. The four inserts 14 are located at the openings of the four bracket mounting slots 9. The inserts 14 limit the fixing claws 13 of the fixed bracket 7 inside the bracket mounting slot 9, preventing them from starting to rotate.

[0026] The water collection mechanism 3 also includes a float 16, a three-way pipe 17, a float support 18, and a sealing plug 20.

[0027] The water inlet of the water storage tank 15 is located on the top plate of the water storage tank 15. A three-way pipe 17 is fixedly installed at the water inlet. The first and second interfaces of the three-way pipe 17 are horizontal, and the third interface of the three-way pipe 17 extends vertically downward through the water inlet into the interior of the water storage tank 15. The collecting pipe 19 has an arc-shaped tubular structure. The inlet of the collecting pipe 19 is vertically upward and is fixedly installed with the collecting plate 21. The outlet of the collecting pipe 19 is horizontal and is fixedly connected to the first interface of the three-way pipe 17. The collecting plate 21 is designed in a blade shape. One end of the second interface of the three-way pipe 17 is closed. A sealing plug 20 is slidably inserted into the second interface of the three-way pipe 17. The end of the sealing plug 20 facing the outlet of the collecting pipe 19 is designed in a frustum shape. A first clearance groove is provided on the side wall of the second interface of the three-way pipe 17, and the second interface of the three-way pipe 17 is connected to the interior of the water storage tank 15 through the first clearance groove.

[0028] A first groove is provided at the lower end of the side wall of the sealing plug 20. A float bracket 18 is rotatably installed inside the water storage tank 15. A float 16 is fixedly installed at one end of the float bracket 18, and the float 16 floats on the water surface inside the water storage tank 15. The other end of the float bracket 18 is slidably engaged with the first groove inside the sealing plug 20. The hinge axis between the float bracket 18 and the water storage tank 15 is located at the water inlet of the water storage tank 15. The float 16 is located below the sealing plug 20 on the side away from the outlet of the collection pipe 19.

[0029] The automatic irrigation mechanism 4 also includes a limiting clamp 25, a limiting strip 26, and a water intake pipe 27.

[0030] A water-drawing pipe 27 is fixedly installed on the inner wall of the water storage tank 15. Both ends of the water-drawing pipe 27 are open. A water-drawing cone 28 is slidably installed vertically inside the water-drawing pipe 27. A second groove is provided on the outer wall of the water-drawing cone 28. A second clearance groove is provided on the side wall of the water storage tank 15, and a third clearance groove is provided on the side wall of the water-drawing pipe 27. The second clearance groove on the side wall of the water storage tank 15 corresponds to the third clearance groove on the side wall of the water-drawing pipe 27. A hinge seat is fixedly installed on the outside of the second clearance groove of the water storage tank 15. The middle part of the support bracket 24 is hinged to the hinge seat. One end of the support bracket 24 is hinged to the lower end of the planting platform 23. The other end of the support bracket 24 passes through the second clearance groove and the third clearance groove in sequence and slides into the second groove on the outer wall of the water-drawing cone 28.

[0031] The one-way ball valve 22 includes a ball valve wall 31, a sealing ball 32, and a limiting spring 33. The ball valve wall 31 is a vertically arranged cylindrical structure with openings on both its top and bottom plates. Water from the water storage tank 15 can enter the ball valve wall 31 through the opening at its lower end, filling it with water. Inside the ball valve wall 31, the sealing ball 32 and the limiting spring 33 are arranged vertically. The upper and lower ends of the limiting spring 33 are connected to the sealing ball 32 and the bottom surface of the ball valve wall 31, respectively. When the sealing ball 32 is not subjected to a downward force, the limiting spring 33's rebound force closes the opening on the top plate of the ball valve wall 31.

[0032] The planting platform 23 is a disc-shaped structure with an open top, and a drainage outlet 29 is provided on the side wall of the planting platform 23.

[0033] The end of the capillary suction tube 30 that connects to the water-drawing cone 28 is flush with the lower end face of the water-drawing cone 28. The middle part of the capillary suction tube 30 passes through the first clearance groove and the second clearance groove.

[0034] A limiting clamp 25 is fixedly installed on the outer wall of the water storage tank 15. The limiting clamp 25 is located above the second clearance groove, and an arc-shaped sliding groove is provided on the inner wall of the limiting clamp 25. A limiting strip 26 is fixedly installed at the lower end of the planting platform 23. The end of the limiting strip 26 away from the planting platform 23 is slidably engaged with the inside of the limiting clamp 25. A sliding post is fixedly installed at the end of the limiting strip 26 away from the planting platform 23. The sliding post is slidably engaged with the inside of the sliding groove. The height of the hinge shaft between the planting platform 23 and the support bracket 24 is equal to the height of the sliding post.

[0035] When the planting platform 23 moves synchronously with the end of the support bracket 24, the planting platform 23 drives the sliding column on the limit strip 26 to slide synchronously inside the sliding groove. Through the cooperation between the sliding column and the sliding groove, the planting platform 23 is kept horizontal during movement.

[0036] The working principle of this invention is as follows: Specialized slope clearing equipment, such as hydraulic breakers and pneumatic drills, is used to clear rock slopes. Larger loose rocks are removed by blasting or hoisting; smaller loose stones and gravel are cleared using a combination of manual labor and machinery. During the clearing process, the slope is strictly adjusted according to the designed gradient to ensure that the slope flatness error is within the allowable range.

[0037] Lay the grid mesh 34 on the slope so that it fits tightly against the slope. Then cover the grid mesh 34 with the cable net 35. Use the nuts and washers that come with the anchor rod 1 to fix the grid mesh 34 and the cable net 35 to the slope. During the fixing process, ensure that the grid mesh 34 and the cable net 35 are taut and there is no looseness.

[0038] Based on the mesh size and spacing of the cable net 35, select a suitable length of fixing claw 13 and install the fixing claw 13 on the corresponding mounting base. Then, install all four mounting bases on the operating table 6. Four insert strips 14 are inserted into the operating table 6. At this time, the four fixing claws 13 are in the open state. The maximum opening angle of the fixing claws 13 is limited by the inner wall of the fixing claw rotation groove on the mounting base, and the insert strips 14 prevent the fixing claws 13 from rotating in the closing direction, thereby ensuring that the four fixing claws 13 on the operating table 6 are fixed.

[0039] Then, the engaging sleeve 5 is fitted onto the tail end of the anchor rod 1, so that the engaging sleeve 5 and the anchor rod 1 are engaged and fixed, thereby fixing the operating platform 6 and the water storage tank 15. Then, all four inserts 14 are pulled out from the operating platform 6, so that the four fixing claws 13 can rotate in the direction of convergence. Then, the fixing claws 13 are pressed, so that the four fixing claws 13 gradually converge and approach the slope. Due to the cooperation of the ratchet 8, the adjustable protrusion 11, and the fixed protrusion 12, the fixing claws 13 can only rotate in one direction towards the slope, and cannot rotate in the direction away from the slope, so that the fixing claws 13 are firmly fixed on the cable net 35 and will not come off, thereby fixing the entire device to the slope.

[0040] When the water level inside the storage tank 15 is low, the float 16 is at a low height. The float 16, through the float bracket 18, moves the sealing plug 20, causing it to be positioned inside the second interface of the three-way pipe 17. The sealing plug 20 is then disconnected from the outlet of the collection pipe 19, allowing the collection pipe 19 to smoothly supply water into the storage tank 15. During rain, rainwater is collected by the collection plate 21 and then flows into the storage tank 15 through the collection pipe 19 and the third interface of the three-way pipe 17 for storage. As the water level inside the storage tank 15 gradually rises, the float 16 also gradually rises. The float 16 drives the float bracket 18 to rotate, causing the float bracket 18 to move the sealing plug 20 in the opposite direction, bringing it closer to the outlet of the collection pipe 19. When the water level inside the storage tank 15 reaches the set height, the sealing plug 20 blocks the outlet of the collection pipe 19, preventing rainwater collected by the collection plate 21 from flowing into the storage tank 15 through the collection pipe 19. When the seed storage bag inside the planting platform 23 has a high water content, it provides sufficient moisture for plant growth. Since the total weight of the planting platform 23 exceeds the weight of the water-drawing cone 28, the end of the support bracket 24 connected to the planting platform 23 is pressed down, causing the water-drawing cone 28 to tilt upwards. This disengages the lower end of the water-drawing cone 28 from the sealing ball 32. Without downward force, the sealing ball 32, under the rebound force of the limiting spring 33, seals the opening on the top plate of the ball valve pipe wall 31. Because the lower end of the water-drawing cone 28 is disengaged from the sealing ball 32, the end of the capillary suction tube 30 also detaches from the water surface and ceases to draw water to the planting platform 23.

[0041] When a prolonged drought causes the slope to dry out and the seed storage bags to lack moisture, the total weight of the planting platform 23 is lighter than the weight of the water-drawing cone 28. This causes the end of the support bracket 24 connected to the planting platform 23 to rise, while the end connected to the water-drawing cone 28 begins to fall, allowing the water-drawing cone 28 to slide downwards inside the water-drawing pipe 27. The lower end of the water-drawing cone 28 contacts the sealing ball 32, applying a downward force to it. The limiting spring 33 is compressed, and the sealing ball 32 disengages from the opening on the top plate of the ball valve pipe wall 31. Water inside the ball valve pipe wall 31 reaches the opening on the top plate of the ball valve pipe wall 31, thus bringing the lower end of the water-drawing cone 28 into contact with water. The end of the capillary suction pipe 30 also comes into contact with water, drawing water from the water storage tank 15 onto the planting platform 23 through capillary action to replenish the seed storage bags.

[0042] When the total weight of the planting platform 23 exceeds the weight of the water-drawing cone 28 again, the end of the support bracket 24 connected to the planting platform 23 is pressed down again, causing the water-drawing cone 28 to tilt upwards. This disengages the lower end of the water-drawing cone 28 from the sealing ball 32. Under the restoring force of the limiting spring 33, the sealing ball 32 closes the opening on the top plate of the ball valve pipe wall 31 again. Since the lower end of the water-drawing cone 28 is disengaged from the sealing ball 32, the end of the capillary suction tube 30 also detaches from the water surface and ceases to draw water and transmit it to the planting platform 23.

[0043] The above process effectively solves the problem that the rock slope has sufficient rainfall but cannot retain moisture, resulting in the inability of vegetation to grow on the slope. At the same time, it does not use sensors, thus avoiding the situation where sensors malfunction due to harsh external environment.

[0044] Since the number of anchor rods 1 on the slope is limited, in order to improve the greening efficiency, multiple sets of devices can be directly installed on the cable net 35. At this time, although there is no anchor rod 1 for support, the four sets of fixing claws 13 can still effectively grab the mesh, realize the relative fixation of the device and the slope. By arranging the drought automatic irrigation device in an array, more growth platforms can be provided for the seed storage bags, thereby realizing large-area greening of the slope.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
