Description

Technical Field

[0001] This invention relates to the field of slope protection technology, specifically to a soil and water conservation slope protection device. Background Technology

[0002] Slope soil erosion refers to the erosion of slope soil caused by natural factors or human activities, resulting in topsoil stripping, nutrient loss, and potentially triggering secondary disasters such as landslides. Using active protective netting to restrain loose soil and rock layers on slopes is one measure to prevent soil erosion. This involves covering the slope with protective netting (high-strength steel wire rope netting) and forming a prestressed anchoring system using anchor rods fixed inside the slope. This system directly inhibits the movement of the surface soil and rock mass by applying pre-tension, thereby preventing soil erosion.

[0003] When traditional protective netting encounters dynamic impacts from rock and soil (typically rockfall impacts or landslide impacts), it firstly suffers from the following problems: as mentioned in the patent publication CN 115787686 B "A Highway Slope Protection Device", the positioning nails (anchors) are easily pulled out of the slope body. This is because the impact kinetic energy of the rock and soil mass is easily transmitted to the anchors through the protective netting, which can easily cause the anchors to overturn or become completely pulled out and fail. Secondly, as mentioned in the patent publication CN 114319235 B "A Water Conservancy Engineering Slope Protection Device", it cannot buffer the impact force received by the slope protection netting. This is because the yield strength threshold of conventional protective netting materials is limited, making it difficult to effectively reduce the instantaneous kinetic energy generated by the high-speed impact of large volumes of rock masses. This often leads to irreversible damage to the netting structure, and subsequently, the loss of its continuous restraint function on the slope rock and soil mass. Summary of the Invention

[0004] This invention addresses the problems of anchor bolts easily overturning or being pulled out entirely due to the traction of the protective net when it is subjected to dynamic impacts from rock and soil, and the difficulty of the protective net effectively dissipating the impact kinetic energy of large volumes of rock. It provides a soil and water conservation slope protection device that can improve the connection strength of the protective net to the slope via anchor bolts, and can also prevent the protective net from being damaged by impact kinetic energy.

[0005] To solve the above problems, the technical solution of the present invention is:

[0006] A soil and water conservation slope protection device includes a protective net. Anchor plates are provided at both ends of the protective net to anchor the top and bottom of the slope. Each anchor plate contains a connector that elastically connects to the end of the protective net. Multiple anchors are symmetrically connected to the left and right sides of the protective net. The left anchor includes a base plate and a rotating plate. An anchor rod is connected to the bottom of the base plate, and a rotating ring is rotatably connected to its outer circumference. A support plate is vertically mounted inside the right side of the rotating ring. A limit strip is rotatably connected to the top of the base plate. The limit strip extends into a radially opened sliding hole at the bottom of the rotating plate. The rotating plate slides along the length of the limit strip. A spring is connected to the left side of the limit strip. A connecting plate for the support plate is provided in the sliding hole on the right side. An inclined hole, lower on the left and higher on the right, is provided on the front and rear sides of the sliding hole corresponding to the position of the connecting plate. A drive rod with both ends extending into the opposite inclined hole is fixed on the connecting plate. The protective net is connected to the top of the rotating plate.

[0007] Furthermore, both anchor plates are hollow plate structures; the connectors at the top and bottom of the slope are symmetrical along the middle of the protective net.

[0008] Furthermore, the connector at the head end of the protective net includes a connecting rod and multiple insert rods. Multiple insert rods are mounted on the anchor plate, and a baffle is connected to the upper end of each insert rod. A connecting rod is slidably provided in the anchor plate on the front side of the multiple insert rods. The front end of the connecting rod is connected to the inner surface of the front side of the anchor plate via a spring. The head end of the protective net moves through the front side plate of the corresponding anchor plate and connects to the connecting rod. A steel wire rope corresponding to the multiple insert rods is provided on the rear side of the connecting rod. One end of each steel wire rope is connected to the lower part of the rear side plate of the anchor plate, and the other end of the steel wire rope moves upward at an angle, moves through the corresponding insert rod, and then bends downward to connect to the lower part of the rear side of the connecting rod.

[0009] Furthermore, the sliding hole is an isosceles trapezoid with a longitudinal section that is wider at the top and narrower at the bottom, and both ends of the sliding hole penetrate the circumference of the rotating plate; the limiting strip is a strip-shaped rod with a longitudinal section that is wider at the top and narrower at the bottom, and the length of the limiting strip is less than the length of the sliding hole.

[0010] Furthermore, both ends of the sliding hole are sealed by sealing plates, and the left end of the limiting strip on the left anchor is connected to the sealing plate at the left end of the sliding hole via a spring; a reinforcing ring is fitted and fixed on the outer periphery of the rotating plate at the location corresponding to the sealing plate.

[0011] Furthermore, the support plate is an arc-shaped plate bent from a rectangular plate, and the lower end of the connecting plate is connected to the middle of the top surface of the support plate.

[0012] Furthermore, an annular groove is provided on the circumferential surface of the base plate, and a limiting rod with its inner end sliding into the annular groove is fixedly mounted on the rotating ring.

[0013] Furthermore, the rotating plate and the base plate are in sliding contact; a rotating rod is connected to the bottom of the limiting strip, and the rotating rod passes through the through hole one and through hole two opened on the base plate in sequence. The diameter of through hole two is larger than that of through hole one. The lower part of the rotating rod is rotatably connected to through hole two via a bearing. A torsion spring is provided inside through hole one and sleeved on the outside of the rotating rod. One end of the torsion spring is connected to one side wall of the through hole and the other end is connected to the rotating rod. The bottom surface of the base plate is provided with a connecting plate for sealing the lower opening of through hole two, and the upper end of the anchor rod is fixed to the connecting plate.

[0014] Furthermore, each of the anchors has a rotating plate with an array of screws on its top surface, a cover plate on the upper side of the rotating plate, a protective net between the cover plate and the rotating plate, and the free ends of the multiple screws passing through the protective net and the cover plate in sequence upwards and being limited by nuts.

[0015] The beneficial effects of the present invention through the above technical solution are as follows:

[0016] 1. When the present invention is connected to the slope, when the protective net is impacted by the rock mass, the head and tail ends of the protective net have room to move within the corresponding anchor plates. The left and right parts of the protective net can drive the rotating plates on the connected anchors to move a certain distance along the direction of the traction force. The protective net has room to move away from the slope. Therefore, the protective net can reduce the impact energy of the rock mass and thus avoid damage to the protective net. Moreover, the impact energy received by the protective net is also converted into the potential energy of spring one, the potential energy of spring two, and the potential energy of the torsion spring, respectively, further reducing the impact energy received by the protective net.

[0017] 2. When the protective net of the present invention is impacted by rock mass, the rotating plate on each anchor can rotate with the deformation of the protective net, thereby reducing the torsional force on the anchor rod on the anchor. Moreover, the protective net provides a traction force to the rotating plate, which can drive the rotating plate to move a certain distance in the direction of the traction force. At this time, the rotating plate drives the support plate on the anchor to move towards the slope. The support plate provides support in a direction with an inclined tendency relative to the rotating plate, thereby reducing the inclination of the anchor and improving the connection strength between the anchor and the slope, thus preventing it from coming off.

[0018] 3. Both anchor plates of the present invention are equipped with insert rods. When the protective net is impacted by the rock mass, the protective net can drive the insert rods on each anchor plate to move downwards, thereby causing the baffles on the insert rods to press down on the anchor plate, ensuring the connection between the anchor plate and the top or bottom of the slope, and further improving the connection strength between the present invention and the slope.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] like Figures 1 to 13As shown, a soil and water conservation slope protection device includes a protective net 1. The protective net 1 has anchor plates 2 at both ends for anchoring the top and bottom of the slope. Each anchor plate 2 has a connector that elastically connects to the end of the protective net 1. Multiple anchors are symmetrically connected to the left and right sides of the protective net 1. The left anchor includes a base plate 3 and a rotating plate 4. The base plate 3 is a circular plate. An anchor rod 5 is connected to the bottom of the base plate 3, and a rotating ring 6 is rotatably connected to its outer circumference. The rotating ring 6 is a circular ring whose inner ring slides in contact with the circumferential surface of the base plate 3. A support plate 7 is movably inserted into the right side of the rotating ring 6. A limiting strip 8 is rotatably connected to the top of the base plate 3. The limiting strip 8 extends into a radially opened sliding hole 9 at the bottom of the rotating plate 4. The rotating plate 4 is a circular plate with a diameter larger than that of the base plate 3. The rotating plate 4 moves along the limiting strip 8... The length direction is slidably connected to the limiting strip 8. A spring 10 is connected to the left side of the limiting strip 8. A connecting plate 11 is provided in the sliding hole 9 on the right side, which is connected to the support plate 7. The width of the connecting plate 11 is smaller than the width of the support plate 7. Corresponding to the position of the connecting plate 11, there are inclined holes 12 on the front and rear sides of the sliding hole 9, which are lower on the left and higher on the right. The inclined hole 12 is a long strip hole that penetrates the circumference of the rotating plate 4 at the right end. The higher end of the inclined hole 12 is at a distance from the top surface of the sliding hole 9. The distance between the upper and lower ends of the connecting plate 11 is smaller than the distance from the top surface of the sliding hole 9 to the lower opening. The purpose is to facilitate the connecting plate 11 to extend into the sliding hole 9. A drive rod 13 is fixed on the connecting plate 11, which extends into the corresponding inclined hole 12 at both ends. The drive rod 13 is a round rod with a diameter that matches the width of the inclined hole 12. The top of the rotating plate 4 is connected to the protective net 1.

[0035] Both anchor plates 2 are hollow plate structures, and the lower opening of each anchor plate is sealed by the lower side plate; the connecting parts at the top and bottom of the slope are symmetrical along the middle of the protective net 1.

[0036] The connector at the head end of the protective net 1 includes a connecting rod 15 and multiple insert rods 14. Multiple insert rods 14 are installed along the length of the anchor plate 2. Each insert rod 14 moves from top to bottom through the anchor plate 2. The upper end of each insert rod 14 is connected to a baffle 16 that contacts the outer top surface of the anchor plate 2. A connecting rod 15 is slidably provided in the anchor plate 2 in front of the multiple insert rods 14. The connecting rod 15 is a rectangular rod that slides in contact with the inner bottom and inner top surfaces of the anchor plate 2. The front end of the connecting rod 15 is connected to the inner front surface of the anchor plate 2 via a spring 17. The head end of the protective net 1 moves through the front side plate of the corresponding anchor plate 2 and connects to the connecting rod 15. The rear side of the connecting rod 15 is provided with steel wire ropes 18 corresponding to the multiple insert rods 14. One end of each steel wire rope 18 is connected to the lower part of the rear side plate of the anchor plate 2. The other end of the steel wire rope 18 moves upward at an angle, passes through the corresponding insert rod 14, and then bends downward to connect to the lower part of the rear side of the connecting rod 15.

[0037] The sliding hole 9 is an isosceles trapezoid with a longitudinal section that is wider at the top and narrower at the bottom. Both ends of the sliding hole 9 penetrate the circumference of the rotating plate 4. The limiting strip 8 is a strip with a longitudinal section that is wider at the top and narrower at the bottom. The length of the limiting strip 8 is less than the length of the sliding hole 9.

[0038] Both ends of the sliding hole 9 are sealed by the sealing plate 19. The left end of the limiting strip 8 on the left anchor is connected to the sealing plate 19 at the left end of the sliding hole 9 via a spring 10. When the rotating plate 4 of the left anchor moves along the length of the limiting strip 8 and the sealing plate 19 at the left end compresses the spring 10, the inclined hole 12 on the rotating plate 4 drives the connecting plate 11 to move downward until the lower end of the support plate 7 is lower than the bottom plate 3. A reinforcing ring 31 is fitted and fixed on the outer periphery of the rotating plate 4 corresponding to the sealing plate 19.

[0039] The connecting plate 11 is a rectangular plate with a width matching the width of the lower opening of the sliding hole 9. The support plate 7 is an arc-shaped plate bent from the rectangular plate. The lower end of the connecting plate 11 is connected to the middle of the top surface of the support plate 7. The bottom surface of the rotating ring 6 is higher than the bottom surface of the base plate 3. When the spring 10 on the anchor is in its natural state, the end of the drive rod 13 on the connecting plate 11 is located inside the end of the inclined hole 12 at its height, and the bottom surface of the support plate 7 is flush with the bottom surface of the rotating ring 6.

[0040] The rotating ring 6 is sleeved on the outside of the base plate 3. The base plate 3 has an annular groove 20 on its circumferential surface. A limiting rod 21 is fixedly mounted on the rotating ring 6 and has its inner end sliding into the annular groove 20. The limiting rod 21 is a round rod whose inner end slides in contact with the annular groove 20.

[0041] The rotating plate 4 and the base plate 3 are in sliding contact; the bottom of the limiting strip 8 is connected to a rotating rod 22, which passes downward through through holes 24 and 29 on the base plate 3. Through holes 24 and 29 are coaxial circular holes and are connected. The diameter of through hole 29 is larger than that of through hole 24. The lower part of the rotating rod 22 is rotatably connected to through hole 29 via a bearing 28. A torsion spring 23 is provided inside through hole 24 and sleeved on the rotating rod 22. One end of the torsion spring 23 is connected to the side wall of through hole 24 and the other end is connected to the rotating rod 22. The torsion spring 23 is located above the bearing 28; the base plate 4 is in sliding contact with the base plate 3. The bottom surface of plate 3 is provided with a connecting plate 30 for sealing the lower opening of through hole 29. The upper end of anchor rod 5 is fixed on the connecting plate 30. The anchor rod 5 includes a rod body 5a and a cone 5b. The rod body 5a is a round rod body. The upper end of the rod body 5a is fixedly connected to the connecting plate 30, and the lower end is connected to the cone 5b with the tip pointing downward. The peripheral wall of the rod body 5a is evenly distributed with barbs 5c with the outer end pointing upward. The barb 5c has an inclination angle of 45°. The barb 5c with an inclination angle of 45° can increase the contact area with the slope and form an effective "self-locking effect", increasing the pull-out resistance of anchor rod 5.

[0042] Each of the anchors has a rotating plate 4 with an array of screws 25 on its top surface. A cover plate 26 is provided on the upper side of the rotating plate 4. The protective net 1 is located between the cover plate 26 and the rotating plate 4. The free ends of the multiple screws 25 pass through the mesh of the protective net 1 and the cover plate 26 in sequence and are limited by nuts 27.

[0043] During installation, the lower parts of multiple insert rods 14 on the anchor plate 2 at the head end of the protective net 1 are inserted into the top of the slope, so that the outer bottom surface of the anchor plate 2 presses against the top of the slope, and the baffle 16 on the insert rod 14 presses against the outer top surface of the anchor plate 2. Similarly, the anchor plate 2 at the tail end of the protective net 1 is fixedly connected to the bottom of the slope via the insert rod 14, and the outer bottom surface of the anchor plate 2 presses against the bottom of the slope, and the baffle 16 on the insert rod 14 presses against the outer top surface of the anchor plate 2. At this time, the springs 17 in the two anchor plates 2 are in their natural state, the protective net 1 between the two anchor plates 2 is laid outside the slope, the anchor rod 5 of each anchor on the protective net 1 is vertically inserted into the slope, and the bottom surface of the connecting plate 30 on each anchor contacts the slope. The connection between the present invention and the slope to be protected is completed.

[0044] When the slope rock mass within the protective netting collapses or a landslide occurs, the rock mass moves along the slope's inclination direction and impacts the protective netting 1 between the two anchor plates 2. When impacted by the rock mass, the protective netting 1 tends to move away from the slope's incline. The head end of the protective netting 1 pulls the connecting rod 15 within the corresponding anchor plate 2 forward. A through hole 32 is provided on the front side plate of the anchor plate 2 for the head end of the protective netting 1 to pass through. The bottom surface of the through hole 32 is a raised, upward-facing arc-shaped surface to prevent the protective netting 1 from being stuck in the through hole 32. At the bend of line 2, the connecting rod 15 compresses the connected spring 17 forward. As the connecting rod 15 moves forward, the front end of each wire rope 18 connected to it moves forward with it. Since each wire rope 18 passes through the upper part of its corresponding insert rod 14, the forward movement of the front end of each wire rope 18 pulls the connected insert rod 14 downwards. The insert rod 14 tends to move downwards, thus causing the baffle 16 connected to the upper end of each insert rod 14 to exert a downward force on the anchor plate 2. This allows the anchor plate 2 to more effectively... Further pressing down on the top of the slope strengthens the connection between the anchor plate 2 and the top of the slope. Similarly, the tail end of the protective net 1 pulls the connecting rod 15 to move backward. The rear side plate of the anchor plate 2 corresponding to the tail end of the protective net 1 has a through hole 33 for the tail end of the protective net 1 to pass through. The top surface of the through hole 33 is a downward-facing arc-shaped surface to prevent the protective net 1 from being stuck at the corner of the through hole 33. The connecting rod 15, driven by the wire rope 18, has a downward tendency to move the corresponding insertion rod 14, thereby strengthening the connection between the anchor plate 2 and the bottom of the slope. In addition to its strength, after the head end of the protective net 1 moves forward a certain distance, the protective net 1 will be lifted up by the slope rock mass that has fallen out inside the protective net 1, which can give the protective net 1 a margin to move away from the slope. In this way, when the rock mass impacts the protective net 1, the protective net 1 has a buffer margin, making the protective net 1 have a flexible protective effect. When the rock mass impacts the protective net 1, it reduces the impact energy of the rock mass, thereby avoiding damage to the protective net 1. Moreover, part of the impact force received by the protective net 1 is converted into the potential energy of the two pairs of springs 17.

[0045] Meanwhile, since the slope surface is inclined, when the rock mass impacts the protective net 1, the protective net 1 undergoes irregular deformation along the slope direction. The direction of the traction force exerted by the protective net 1 on the anchor is constantly changing. Therefore, the anchor needs to be adjusted according to the traction direction of the protective net 1 to buffer the traction force of the protective net and ensure the stable connection between the anchor and the slope. Taking the left anchor as an example, when the rock mass moves along the slope and impacts the protective net 1, causing the left side of the protective net 1 to deform along the slope direction, that is, the left side of the protective net 1 will pull the rotating plate 4 of the connected anchor to rotate clockwise. The rotation of the rotating plate 4 can buffer the traction force of the protective net 1, preventing the traction force of the protective net 1 from causing torsion of the anchor rod 5. Moreover, when the rotating plate 4 rotates, the rotating plate 4 drives the rotating rod 22 to rotate via the limiting strip 8, and the torsion spring 23 outside the rotating rod 22 is torsion. Part of the traction force on the rotating plate 4 is converted into the potential energy of the torsion spring 23. In addition, the rotation of the rotating plate 4 will drive the rotating ring 6 to rotate clockwise along the circumference of the base plate 3 via the connecting plate 11 and the support plate 7. Moreover, as the traction force of the protective net 1 on the rotating plate 4 increases, the rotating plate 4 moves along the length direction of the connected limiting strip 8. The limiting strip 8 and the sliding... Spring 10 between holes 9 is compressed by the sealing plate 19 at the left end. Part of the traction force on the rotating plate 4 is converted into the potential energy of spring 10. When the rotating plate 4 moves along the length of the connected limiting strip 8, the inclined hole 12 on the rotating plate 4 presses against the drive rod 13 on the connecting plate 11, causing the connecting plate 11 to drive the support plate 7 downward until the lower end of the support plate 7 is lower than the bottom surface of the bottom plate 3 and contacts the extrusion slope. At this time, the support plate 7 will support the side of the rotating plate 4 that has a tendency to tilt, to prevent the rotating plate 4 from tilting the anchor rod 5 due to the traction of the protective net 1. The greater the traction force on the rotating plate 4, the better. The greater the downward force exerted by the inclined hole 12 on the rotating plate 4 on the support plate 7, the greater the supporting reaction force exerted by the support plate 7 on the rotating plate 4. Although the magnitude and direction of the traction force on each anchor on the left side of the protective net 1 are different, when the rotating plate 4 on the left anchor is only pulled to the right by the protective net 1, the rotating plate 4 on the anchor does not rotate. At this time, the support plate 7 is located on the lower right side of the rotating plate 4, and the protective net 1 has a tendency to pull the left anchor to tilt to the right. When the rotating plate 4 moves to the right along the length direction of the limiting strip 8 due to the traction, the spring 10 in the left side of the rotating plate 4 is compressed. The right side of the rotating plate 4 drives the support plate 7 to move downward through the inclined hole 12 to contact the top pressure slope and support the right end of the rotating plate 4.Alternatively, when the rotating plate 4 on the left anchor is pulled downwards and to the right by the protective net 1, the rotating plate 4 rotates due to the pull of the protective net 1. When the rotating plate 4 rotates, the right end of the rotating plate 4 remains consistent with the pull direction of the protective net 1. The support plate 7 rotates with the rotating plate 4 via the connecting plate 11. The support plate 7 remains located on the lower side of the end of the rotating plate 4 that is consistent with the pull direction of the protective net 1. Moreover, the spring 10 and the limiting strip 8 inside the rotating plate 4 move synchronously with the rotating plate 4. When the left anchor is pulled downwards and to the right by the protective net 1, it tends to tilt in the direction of the pull force of the protective net 1. When the sealing plate 19 at the left end of the rotating plate 4 compresses the spring 10, the oblique hole 12 on the rotating plate 4 can drive the support plate. 7 moves downwards to contact the top of the slope. The support plate 7 supports the rotating plate 4 of the left anchor, which tends to tilt downwards and to the right. Therefore, the support plate 7 is always located on the side of the rotating plate 4 that tends to tilt, providing support to the rotating plate 4. Similarly, the rotating plates 4 of the multiple anchors on the right side of the protective net 1 can rotate counterclockwise under the traction of the protective net 1. When the rotating plate 4 moves along the length direction of the connected limiting strip 8, the inclined hole 12 on the rotating plate 4 presses against the drive rod 13 on the driving connecting plate 11, causing the connecting plate 11 to drive the support plate 7 downwards. The support plate 7 on each rotating plate 4 can provide a supporting reaction force to the rotating plate 4. Therefore, the present invention can improve the connection strength between the anchor and the slope, preventing tilting and detachment.
