Description

Technical Field

[0001] This invention relates to the field of soil and water conservation technology, specifically to a protective device for preventing soil and water loss from vegetation on slopes. Background Technology

[0002] Preventing soil erosion after slope greening is a comprehensive project aimed at protecting the root system of vegetation to maintain a stable soil structure, reducing erosion caused by rainwater runoff, and beautifying the environment. Generally, the greening plants chosen for slope protection are those with deep root systems, such as herbs, shrubs, or trees. These root systems help reinforce the deep soil structure and prevent erosion. Planting high-coverage ground cover plants creates a dense ground cover, reducing the chance of water directly impacting the soil surface.

[0003] Therefore, vegetation plays a significant role in preventing soil erosion, but this is contingent on the soil and water being well-preserved. The two processes are mutually reinforcing. Thus, in addition to using vegetation for soil and water conservation, engineering projects often incorporate additional protective measures to prevent soil erosion. For example, the most common measure is slope protection netting, which involves laying anti-corrosion netting or ecological bags on slopes to provide initial protection for newly planted plants until their root systems are sufficiently strong. Alternatively, retaining walls can be constructed, with small retaining walls or terraces built where necessary to slow water flow and increase soil deposition. Furthermore, a well-designed drainage system guides rainwater to low-lying areas or collection ponds, preventing concentrated runoff from eroding slopes.

[0004] Among the existing technologies mentioned above, regarding slope protection nets, anti-slide slope protection nets are formed by interlocking several strands of steel wire into rings. This type of net is suitable for high mountains and steep slopes with buffer zones next to buildings and facilities, effectively intercepting disasters such as rockfalls, flying rocks, avalanches, and mudslides, preventing damage to buildings and facilities. Three-dimensional vegetation net slope protection, on the other hand, is a slope protection method using polyethylene material, mainly used for greening, planting grass, and soil stabilization. By laying this net on the slope, it can effectively prevent soil erosion while simultaneously providing vegetation cover, achieving the dual effects of soil stabilization and greening. This slope protection method is suitable for the protection of steep slopes and has high tensile strength. While these slope protection nets possess excellent slope protection properties and can effectively prevent soil erosion, they have a significant drawback: after prolonged use, they rust or age, causing the mesh structure to collapse and rendering them ineffective. Furthermore, the rotting of these nets within the vegetation can harm plant growth. In addition, existing protective nets are primarily laid on the slope surface during or before planting, meaning their effectiveness in intercepting water and soil is mainly limited to the topsoil, with little impact on deeper soil layers.

[0005] Therefore, how to obtain a soil and water conservation device that can both prevent soil and water loss from slope vegetation and be replaced and recycled in a timely and convenient manner is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a protective device for preventing soil and water loss from slope vegetation, so as to solve the problems mentioned in the background art. It is convenient to replace and recyclable, and can also assist existing soil and water loss prevention facilities to greatly reduce the possibility of soil and water loss from slope vegetation growth.

[0007] This invention is achieved through the following technical solution:

[0008] A protective device for preventing soil erosion by vegetation on slopes includes several anchor cylinders pre-installed on the slope. The anchor cylinders are set perpendicular to the slope surface, and the bottom end of the anchor cylinder is a solid conical structure so as to be inserted into the hard rock and soil layer of the slope. All anchor cylinders are arranged in a rectangular array on the slope surface. Between two adjacent anchor cylinders on the same horizontal line, there is a soil-retaining rope, which is covered by the soil covering the slope surface. A rotating shaft is coaxially rotatably installed inside the anchor cylinder. The rotating shaft has several winding shaft segments along its length. Each soil-retaining rope is wound around the corresponding winding shaft segment, so that when one of the rotating shafts is rotated to a set number of revolutions, the section of soil-retaining rope buried in the soil between the pair of adjacent anchor cylinders is collected on one of the rotating shafts, and at this time, the section of soil-retaining rope arranged between the adjacent anchor cylinders is released from the other rotating shaft.

[0009] Furthermore, an additional cylinder is provided between two adjacent anchor cylinders. The additional cylinder is located in the center between the two adjacent anchor cylinders and is also fixed on the slope. The inner hole size of the additional cylinder is designed to allow a camera to be inserted vertically. The camera can capture real-time images of the earth-retaining rope passing through the additional cylinder.

[0010] Furthermore, rubber sleeves are embedded in the walls of the anchor cylinder and the auxiliary cylinder, through which the retaining rope slides.

[0011] Furthermore, the earth-blocking rope includes a wear-resistant rubber sleeve and a steel rope embedded in the wear-resistant rubber sleeve.

[0012] Furthermore, a winding wheel is coaxially fixed at the winding shaft section on the rotating shaft, and the soil-blocking rope is wound on the winding wheel.

[0013] Furthermore, several fishbone rods are provided on the line connecting each pair of anchor cylinders. The fishbone rods include a main rod and support rods fixed on both sides of the main rod. The main rod is set parallel to the anchor cylinder, and multiple support rods are set at intervals along the length of the main rod. The bottom end of each support rod is inclined downwards, and two support rods at the same height are distributed in a V-shape. The bottom ends of the main rod and the bottom ends of the support rods are both pointed tips that can be inserted into the rock and soil.

[0014] Furthermore, the top of the rotating shaft has a hexagonal slot into which the motor spindle is inserted to drive the rotating shaft to rotate; the top port of the anchor tube is threaded with a locking cover. When the locking cover is tightened, its inner bottom surface abuts against the top of the rotating shaft and axially presses the rotating shaft, and the locking cover rotates exactly to the position where the first connecting ear fixed on its side is directly opposite the second connecting ear on the side wall of the anchor tube. Each of the two connecting ears has a locking hole that can be coaxial at this time. The lock passes through the locking hole to lock the locking cover to the top of the anchor tube.

[0015] Furthermore, the top of the anchor tube has a disc with a diameter larger than that of the anchor tube, which is coaxially located at the top. The disc has a circular cavity coaxial with the central hole of the anchor tube. A driven internal gear ring is rotatably mounted coaxially in the side wall of the circular cavity. A driving gear meshes with the inner side of the driven internal gear ring. The driving gear can intermittently mesh with an independent gear tooth fixed on the rotating shaft, so that when the rotating shaft rotates once, the independent gear tooth meshes with the driving gear by one tooth.

[0016] Furthermore, a T-shaped groove coaxial with the inner wall of the circular cavity located above the driven internal gear ring is provided. A positioning slide block is slidably connected in the T-shaped groove. After the positioning slide block is fixed in the T-shaped groove, when the driven internal gear ring rotates at a set angle, a limiting block fixed on the driven internal gear ring abuts against the positioning slide block and stops rotating. At this time, the section of the earth-blocking rope that was originally buried in the soil between adjacent anchor cylinders is completely taken into the winding shaft section.

[0017] Furthermore, the positioning slide includes a vertically arranged stop bar, a T-bolt, and a locking nut. The cross-section of the middle section of the T-bolt is rectangular, and the top of the stop bar has a rectangular hole that is coaxially fitted with the middle section. When the threaded section of the T-bolt is tightened by the locking nut, the locking nut presses against the side of the stop bar and fixes the stop bar to the side wall of the circular cavity.

[0018] The beneficial effects of this invention are as follows:

[0019] This protective device for preventing soil and water loss from slope vegetation can be used alone or in conjunction with existing slope protection nets. It is essentially based on the ground fence structure used in daily production and life. Through the intermittent arrangement of pre-embedded anchor cylinders and soil-retaining ropes, a soil-retaining net structure is formed. It can effectively intercept and bear the soil on the slope when the roots of vegetation are spread. Its interception effect covers the entire soil layer and can effectively prevent large-scale soil and water loss.

[0020] Moreover, since the retaining ropes are embedded in the soil, when the shaft is rotated, the retaining ropes can be stored in the corresponding anchor cylinders, and then a new retaining rope can be pulled out from another anchor cylinder. This allows the retaining net formed by the combination of retaining ropes to be quickly and automatically replaced without excavating and damaging the slope vegetation. In addition, the fishbone poles and auxiliary cylinders make the protective net for intercepting soil erosion more reliable, especially suitable for slope protection on both sides of main roads. Because the slope protection in this case is extremely safe and the cost is also high, it can be combined with traditional protective fences, nets and other forms to further enhance the protection and ensure the safety of both sides of the road slope.

The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Please see Figure 1-2The present invention provides a technical solution: a protective device for preventing soil and water loss from slope vegetation includes several anchor cylinders 1 pre-installed on the slope. The key is that these anchor cylinders 1 are set perpendicular to the slope surface, and the bottom end of the anchor cylinder 1 is a solid conical structure so as to be inserted into the hard rock and soil layer of the slope for fixation. Therefore, before planting vegetation at the location of slope construction, these anchor cylinders 1 need to be pre-fixed on the slope in a form similar to anchor rods. Specifically, during construction, all anchor cylinders 1 are arranged in a rectangular array on the slope surface, meaning there are several rows of anchor cylinders 1 facing the slope. Furthermore, adjacent anchor cylinders 1 on the same horizontal line are specifically connected by soil-retaining ropes 2. During construction, these soil-retaining ropes 2 are covered by soil. That is, after installing the anchor cylinders 1 and soil-retaining ropes 2, backfill soil is dumped and then used for planting vegetation. Therefore, 90% of this protective device is buried in the soil. These densely packed anchor piles and soil-retaining ropes 2 together form a protective net to prevent soil erosion, preventing rainwater from washing away the soil on which the vegetation depends for survival. More detailed, such as... Figure 2 As shown, in this embodiment, a rotating shaft 3 is coaxially installed inside the anchor cylinder 1. Several winding shaft segments are provided along the length of the rotating shaft 3. Each earth-blocking rope 2 is wound around the corresponding winding shaft segment. For two adjacent anchor cylinders 1, when one of the rotating shafts inside one anchor cylinder 1 is rotated to a set number of revolutions, the section of earth-blocking rope 2 buried in the soil between the two adjacent anchor cylinders 1 will be collected onto the aforementioned rotating shaft. At this time, the earth-blocking rope 2 arranged between the adjacent anchor cylinders 1 becomes a new section of earth-blocking rope 2 that has just been released onto the other rotating shaft, thereby realizing the replacement of the earth-blocking rope 2 in the soil. This protective structure does not require excavating the slope again to replace the protective net. Moreover, in engineering practice, traditional protective facilities such as plastic mesh, once buried in the slope, are not replaceable. They can only gradually age and break over time, eventually losing their earth-blocking effect. It is impossible to excavate the slope again to replace the protective net and other facilities.

[0035] In this embodiment, to enhance protection, an auxiliary cylinder 6 can be provided between two adjacent anchor cylinders 1. The auxiliary cylinder 6 is located in the center between the two adjacent anchor cylinders 1 and is also pre-fixed to the slope. Furthermore, a special feature is that, in this embodiment, the inner diameter of the auxiliary cylinder 6 is designed to allow a camera 7 to be vertically inserted. Maintenance personnel can later insert the camera 7 into the auxiliary cylinder 6, and then... Figure 3The image shows a real-time view of the retaining rope 2 passing through the auxiliary cylinder 6, allowing for assessment of its damage and timely replacement. In practice, rubber sleeves 5 can be embedded in the walls of the anchor cylinder 1 and the auxiliary cylinder 6, allowing the retaining rope 2 to slide through. This allows for the removal of surface soil when storing and replacing the retaining rope 2, making it easier to collect on the winding shaft and ensuring its quality and quantity for centralized recycling after the anchor cylinder 1 is removed. When recycling is needed, a small hole can be dug along the path of the retaining rope, the exposed rope can be cut, the corresponding shaft 3 can be rotated, and the corresponding anchor cylinder 1 can be pulled out to retrieve the retaining rope, preventing it from rotting and remaining in the soil. In specific manufacturing, it is best to make the retaining rope 2 into a structure that includes a wear-resistant rubber sleeve and a steel rope embedded in the wear-resistant rubber sleeve. In this way, the wear-resistant rubber sleeve can play a role in preventing corrosion and protecting the internal steel strands and other steel ropes. When the camera 7 captures a large area of ​​aging and falling off of the wear-resistant rubber sleeve, it can be promptly recycled and replaced, making the steel rope recycling more timely and thorough, and avoiding the problem of increased waste due to the use of metal materials. In addition, in order to make the winding speed faster, a winding wheel 4 can be coaxially fixed at the winding shaft section on the rotating shaft 3. The diameter of the winding line is larger than that of the rotating shaft 3, so that the retaining rope 2 can be wound quickly onto the winding wheel 4. That is, for every rotation of the main shaft, a longer length of retaining rope 2 is recycled, and the replacement speed of retaining rope 2 is faster.

[0036] In this embodiment, to further enhance the soil interception effect, several fishbone rods are specially installed along the line connecting every two anchor cylinders 1 to form a denser mesh structure with the soil-blocking rope 2. Specifically, as... Figure 8 This fishbone pole includes a main pole 8 and support poles 9 fixed on both sides of the main pole 8. The main pole 8 is set parallel to the anchor cylinder 1, and multiple support poles 9 are spaced apart along the length of the main pole 8. The bottom end of each support pole 9 is inclined downward to form a fishbone structure, and two support poles 9 at the same height are distributed in a V-shape. The bottom ends of the main pole 8 and the bottom ends of the support poles 9 are pointed tips that can be inserted into the soil, thus firmly fixing the fishbone pole while enhancing its soil-retaining function. The fishbone pole can be pre-fixed to the slope with the anchor cylinder 1, or it can be directly inserted later. Because the size of the fishbone is very small relative to the area of ​​the slope vegetation, it is easy to insert directly into the vegetation and will not seriously damage the vegetation root system.

[0037] As one of the specific implementation structures, in order to facilitate the rotation of the rotating shaft 3, such as Figure 4-5At the top of the rotating shaft 3 is a hexagonal slot into which the motor spindle is inserted to drive the rotating shaft 3 to rotate rapidly. A locking cover 10 is threaded into the top port of the anchor cylinder 1. When the locking cover 10 is tightened, its inner bottom surface abuts against the top of the rotating shaft 3, axially pressing the rotating shaft 3. After the spindle rotates a set number of times, the rotating shaft 3 is fixed. Furthermore, when the locking cover 10 presses against the rotating shaft 3, it also rotates to the position where its first connecting lug 12, fixed to its side, is directly opposite the second connecting lug 13 on the side wall of the anchor cylinder 1. Each of these two connecting lugs has a locking hole that allows it to be coaxial at this time. A lock passes through the locking hole, locking the locking cover 10 to the top of the anchor cylinder 1, thus preventing unauthorized personnel from operating this protective device.

[0038] In this embodiment, as Figure 4-5 As shown, during the actual manufacturing process, a disc 11 with a diameter larger than that of the anchor cylinder 1 needs to be coaxially mounted at the top of the anchor cylinder 1. This disc 11 has a circular cavity 1101 coaxial with the central hole of the anchor cylinder 1. A driven internal gear ring 14 is coaxially rotatably mounted inside the side wall of this circular cavity 1101. A driving gear 15 is meshed inside the driven internal gear ring 14. The driving gear 15 can intermittently mesh with an independent gear tooth 16 fixed on the rotating shaft 3, so that when the rotating shaft 3 rotates one revolution, the independent gear tooth 16 meshes with the driving gear 15 by one tooth. For example, in the above embodiment, the driving gear 15 has 30 teeth, while the driven internal gear ring 14 has 60 teeth, resulting in a transmission ratio of 0.5. Therefore, the shaft 3 needs to rotate 30 times for the driving gear 15 to rotate once, while the driven internal gear ring 14 can only rotate half a turn. If the driven gear ring is to eventually rotate once, then the shaft 3 needs to rotate 60 times. Assuming the diameter of the winding wheel 4 or the winding shaft section of the shaft 3 is 20cm, then the shaft 3 can hold at least 37.68m of earth-blocking rope 2 after rotating 60 times. The actual length should be larger than this value because the diameter of the coil formed by the earth-blocking rope 2 will increase compared to 20cm as the winding progresses. Therefore, only one driving gear 15 is needed for speed change, which is sufficient to hold the corresponding section of earth-blocking rope 2. Generally, a distance of less than 10 meters between adjacent anchor cylinders 1 is sufficient. Therefore, the above transmission structure design is compact and small in size, yet it is an ideal structure that can meet any design requirements in construction.

[0039] In this embodiment, in order to control the rotation angle of the driven internal gear ring 14, that is, to control it within a range of less than or equal to one revolution, the specific degree of rotation can be determined as follows: Figure 4-6As shown, a T-shaped groove 17, coaxial with the circular cavity 1101, is provided on the inner wall above the driven internal gear ring 14. A positioning slide block 19 is slidably connected within the T-shaped groove 17. After the positioning slide block 19 slides into place within the T-shaped groove 17, it can be fixed at the corresponding position on the T-shaped groove 17. In use, when the driven internal gear ring 14 rotates to a set angle, a limiting block 20 fixed on the driven internal gear ring 14 will inevitably come into contact with the positioning slide block 19, thereby stopping the rotation. At this time, the section of the earth-blocking rope 2 originally buried in the soil between adjacent anchor cylinders 1 is completely stored on the winding shaft section, and a new section of earth-blocking rope 2 released from another rotating shaft is replaced. As one of the implementation details, such as Figure 6-7 In this embodiment, the positioning slide 19 includes a vertically arranged stop bar 1904, a T-bolt, and a locking nut 1903. The sliding nut 18 of the T-bolt is slidably installed within the T-shaped groove 17. The cross-section of the middle section 1901 of the T-bolt is machined into a rectangle. The top of the stop bar has a rectangular hole coaxially fitted with the middle section 1901, preventing relative rotation after insertion. When the threaded section 1902 of the T-bolt is tightened by the locking nut 1903, as... Figure 7 The locking nut 1903 presses against the side of the stop bar 1904, thereby fixing the stop bar 1904 to the side wall of the circular cavity 1101 so that it can collide and contact with the aforementioned limiting block 20, thereby achieving automatic control of the length of the earth-blocking rope 2.
