Description

Technical Field

[0001] The invention relates to the technical field of soil and water loss protection, and in particular to a protection device for preventing soil and water loss of green plants on a slope. Background Art

[0002] Preventing soil erosion after greening of slope areas is a comprehensive project aimed at protecting the roots of vegetation with a stable soil structure, reducing erosion caused by rainwater erosion, and beautifying the environment. Generally, the green plants selected to prevent soil erosion on slopes are plants with roots that penetrate deep into the soil, such as herbs, shrubs or trees. The roots of these plants help to reinforce the deep soil structure and prevent erosion. Planting ground cover plants with high coverage rate forms a tight ground cover to reduce the chance of water flow directly impacting the soil surface.

[0003] Therefore, green plants are of great significance to the prevention and control of soil erosion, but the premise is that the soil and water themselves can be well preserved. The two are a complementary process. Therefore, in addition to using green plants to maintain soil and water, some additional protective facilities are added to the project to prevent soil erosion. For example, the most common is the slope protection net, which is to lay anti-erosion nets or ecological bags on the slope to provide initial protection for newly planted plants until their roots develop strong enough. Or set up retaining walls, build small retaining walls or terraces where necessary, slow down the flow of water, and increase the chance of soil deposition. In addition, set up a reasonably laid out drainage system to guide rainwater to low-lying areas or collection pools to avoid concentrated runoff erosion of the slopes.

[0004] Among the above existing technologies, as far as slope protection nets are concerned, anti-slip slope protection nets are formed by several strands of steel wire coiled into a ring and interlocked. This type of protection net is suitable for high mountains and steep hills with buffer zones next to building facilities. It can effectively intercept disasters such as rockfalls, flying rocks, snow avalanches, and mudslides to prevent these disasters from destroying building facilities. The three-dimensional vegetation net slope protection is a slope protection method using polyethylene material, which is mainly used for greening, planting grass and consolidating soil. By laying this net on the slope, it can effectively prevent soil erosion and cover it with vegetation at the same time, achieving the dual effects of soil consolidation and greening. This slope protection method is suitable for the protection of high and steep slopes and has high strength and tensile resistance. Although these slope protection nets have excellent slope protection properties and can prevent soil erosion very well, they do have a major flaw. After long-term use, this type of protection net will rust or age, causing the mesh structure to collapse and no longer play a protective role. Moreover, it will rot in the soil of green plants and cause damage to the growth of green plants. In addition, the existing protection nets are basically laid on the slope surface when or before the green plants are planted. Therefore, their function of intercepting water and soil is mainly aimed at the surface soil, while the deeper soil does not have obvious interception properties.

[0005] Therefore, how to obtain a soil erosion protection device to prevent soil erosion of slope green plants and to replace and recycle them in a timely and convenient manner is a problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a protective device for preventing soil erosion of green plants on slopes to solve the problems raised in the background technology. While it is easy to replace and recycle, it can also assist existing soil erosion protection facilities to greatly reduce the possibility of soil erosion caused by the growth of green plants on slopes.

[0007] The present invention is achieved through the following technical solutions:

[0008] A protective device for preventing soil and water loss of green plants on a slope comprises a plurality of anchor barrels pre-installed on the slope, wherein the anchor barrels are arranged perpendicular to the slope surface, the bottom ends of the anchor barrels are solid cone-shaped structures so as to be inserted into the hard rock and soil layers of the slope, all the anchor barrels are arranged in a rectangular array on the slope surface, and soil-retaining ropes are connected between two adjacent anchor barrels on the same horizontal line, and the soil-retaining ropes are covered by the soil covered by the slope surface; a rotating shaft is coaxially rotatably installed in the anchor barrel, and the rotating shaft has a plurality of winding shaft sections along its length direction, and each of the soil-retaining ropes is wound on the corresponding winding shaft section, 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 barrels is received on one of the rotating shafts, and at this time, a section of soil-retaining rope released from the other rotating shaft is arranged between the adjacent anchor barrels.

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

[0010] Furthermore, a rubber sleeve is embedded in the cylinder wall of the anchor cylinder and the additional cylinder, and the earth-blocking rope passes through the rubber sleeve in a sliding manner.

[0011] Furthermore, the earth-retaining 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 to the winding shaft section on the rotating shaft, and the soil-blocking rope is wound around the winding wheel.

[0013] Furthermore, a plurality of fishbone rods are provided on the connecting line between every two anchor barrels. The fishbone rods include a main rod and support rods fixed on both sides of the main rod. The main rod is arranged parallel to the anchor barrel, and a plurality of support rods are arranged at intervals in the length direction of the main rod. The bottom end of each support rod is inclined downward, and the two support rods at the same height are distributed in a herringbone shape; the bottom ends of the main rod and the support rod are both pointed ends that can be inserted into rock and soil.

[0014] Furthermore, the top of the rotating shaft has a hexagonal slot for inserting the main shaft of the power supply motor to drive the rotating shaft to rotate; the top port of the anchor barrel is threadedly matched with a locking cover, and when the locking cover is tightened, its inner bottom surface contacts and contacts with the top of the rotating shaft to axially compress the rotating shaft, and the locking cover is rotated to a position where the first connecting ear fixed on its side is opposite to the second connecting ear on the side wall of the anchor barrel, and the two connecting ears each have a locking hole that can be coaxial at this time, and the lock passes through the locking hole to lock the locking cover to the top of the anchor barrel.

[0015] Furthermore, the top end of the anchor barrel is coaxially provided with a disc having a diameter larger than that of the anchor barrel, and the disc is provided with a circular cavity coaxial with the center hole of the anchor barrel, and a driven inner gear ring is coaxially rotatably installed in the side wall of the circular cavity, and a driving gear is meshed on the inner side of the driven inner gear ring, and the driving gear can intermittently mesh with an independent gear tooth fixed on the rotating shaft, so that when the rotating shaft rotates one circle, the independent gear tooth meshes with the driving gear by one gear tooth.

[0016] Furthermore, a T-shaped groove coaxial with the circular cavity is provided on the inner wall above the driven inner gear ring, and a positioning slide is slidably connected in the T-shaped groove. After the positioning slide is fixed in the T-shaped groove, when the driven inner gear ring rotates to a set angle, a limit block fixed on the driven inner gear ring contacts and contacts the positioning slide and stops rotating. At this time, the section of the earth-retaining rope originally buried in the soil between adjacent anchor cylinders is just completely received on the winding shaft section.

[0017] Furthermore, the positioning slide includes a vertically arranged baffle, a T-bolt and a locking nut, wherein the cross-section of the middle section of the T-bolt is rectangular, and the top end of the baffle has a rectangular hole coaxially sleeved with the middle section, and when the threaded section of the T-bolt is tightened by the locking nut, the locking nut presses against the side of the baffle to fix the baffle on the side wall of the circular cavity.

[0018] The beneficial effects of the present invention are:

[0019] The protective device for preventing soil and water loss of green plants on the slope can be used alone or in combination with the existing slope protection net. Its essence is to refer to the ground fence structure used in daily production and life. Through the pre-buried anchor cylinders and soil-retaining ropes arranged at intervals, a soil-retaining net structure is formed. It can well produce an overall interception and bearing effect on the slope soil when the roots of green plants are spread. Its interception effect is spread throughout the entire soil layer, which can better avoid large-scale soil and water loss.

[0020] Moreover, since the earth-blocking ropes are set in the soil, when the rotating shaft is rotated, the earth-blocking ropes can be stored in the corresponding anchor barrels, and then a new earth-blocking rope in another anchor barrel is pulled out, so that the barrier net formed by the combination of earth-blocking ropes can be quickly and automatically replaced without excavating and destroying the slope vegetation. In addition, the role of the fishbone rod and the additional barrel makes the protective net for intercepting soil erosion more reliable, especially suitable for slope protection on both sides of the main road. Because the slope protection in this occasion is extremely safe and the cost itself is also high, it can be equipped with traditional protective fences, nets and other forms for comprehensive use, which can further enhance the protection and ensure the safety of both sides of the road slope.

[0021] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] See also Figure 1-2The present invention provides a technical solution: a protective device for preventing soil erosion of green plants on a slope includes a plurality of anchor cylinders 1 pre-installed on the slope. The key point is that these anchor cylinders 1 are arranged perpendicular to the slope surface, and the bottom end of the anchor cylinder 1 is a solid cone tip structure so that it can be inserted into the hard rock and soil layer of the slope to achieve fixation. Therefore, before planting green plants at the place where the slope is built, it is necessary to pre-fix these anchor cylinders 1 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, that is, facing the slope, there are several rows of anchor cylinders 1, and between two adjacent anchor cylinders 1 on the same horizontal line, there are specially connected earth-blocking ropes 2. During construction, these earth-blocking ropes 2 are covered by soil, that is, after the anchor cylinders 1 and earth-blocking ropes 2 are installed, the soil is dumped backfilled and then used for planting green plants. Therefore, 90% of the protective device is buried in the soil. These densely distributed anchor piles and earth-blocking ropes 2 together construct a protective net to prevent soil erosion, so as to prevent green plants from losing the soil they depend on for survival after being washed away by rainwater. In more detail, if Figure 2 As shown, the present embodiment requires a rotating shaft 3 to be coaxially rotatably installed in the anchor barrel 1, and the rotating shaft 3 has a plurality of winding shaft sections along its length direction, and each earth-retaining rope 2 is wound on the corresponding winding shaft section. For two adjacent anchor barrels 1, when one of the rotating shafts provided in one of the anchor barrels 1 is rotated to a set number of revolutions, the section of earth-retaining rope 2 buried in the soil between the pair of adjacent anchor barrels 1 will be received on one of the above-mentioned rotating shafts, and at this time, the earth-retaining rope 2 arranged between the adjacent anchor barrels 1 becomes a new section of earth-retaining rope 2 just released on the other rotating shaft, thereby realizing the replacement of the earth-retaining rope 2 in the soil. This protective structure does not require re-excavating the slope to replace the protective net, and in terms of engineering practice, traditional protective facilities such as plastic grids, once buried in the slope, are not replaceable themselves, and can only gradually age and break with the passage of time, and then lose the soil retaining effect, and it is impossible to re-excavate the slope to replace facilities such as the protective net.

[0035] In this embodiment, in order to improve the protection, an additional cylinder 6 can be provided between two adjacent anchor cylinders 1. The additional cylinder 6 is located in the center between the two adjacent anchor cylinders 1 and is also pre-fixed on the slope. Moreover, a special function is that in this embodiment, the size of the inner hole of the additional cylinder 6 is based on the size of a camera 7 that can be placed vertically. The maintenance personnel can later place the camera 7 into the additional cylinder 6, and then Figure 3As shown, a real-time image of the earth-blocking rope 2 passing through the additional cylinder 6 is captured, so as to determine the damage of the earth-blocking rope 2 so as to consider timely updating. In practice, a rubber sleeve 5 can be embedded in the cylinder wall of the anchor cylinder 1 and the additional cylinder 6, and the rubber sleeve 5 is slidably fitted for the earth-blocking rope 2 to pass through, so that when the earth-blocking rope 2 is stored and replaced, the soil on its surface can be scraped off and better stored on the winding shaft section, so that after the anchor cylinder 1 is taken out later, it can be recycled and reused in a centralized manner with guaranteed quality and quantity. When recycling is needed, a small hole can be excavated locally on the intercepting rope path, and then the exposed intercepting rope can be cut off, the corresponding rotating shaft 3 can be rotated, and then the corresponding anchor cylinder 1 can be pulled out to realize the recycling of the intercepting rope, while also preventing it from rotting and remaining in the soil. When making it specifically, it is best to make the earth-blocking rope 2 into a structure including a wear-resistant rubber sleeve and a steel rope embedded in the wear-resistant rubber sleeve, so that the wear-resistant rubber sleeve can play an anti-corrosion role and protect the internal steel strands and other steel ropes. When the camera 7 captures the large-scale aging and shedding of the above-mentioned wear-resistant rubber sleeve, it is promptly recovered and replaced, and the steel rope is recovered more timely and fully, without causing 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, and the diameter of the winding line is larger than the rotating shaft 3, so that the earth-blocking rope 2 can be quickly wound on the winding wheel 4, that is, the main shaft rotates one circle, the length of the recovered earth-blocking rope 2 is longer, and the speed of updating the earth-blocking rope 2 is faster.

[0036] In this embodiment, in order to further improve the interception effect of soil, a plurality of fishbone rods can be specially provided on the connection line between each two anchor cylinders 1, so as to form a denser mesh structure with the soil-blocking rope 2. Specifically, Figure 8 The fishbone rod comprises a main rod 8 and support rods 9 fixed on both sides of the main rod 8. The main rod 8 is arranged parallel to the anchor tube 1, and a plurality of support rods 9 are arranged at intervals in the length direction of the main rod 8. The bottom end of each support rod 9 is arranged to be tilted downward to form a fishbone structure, and the two support rods 9 at the same height are distributed in a herringbone shape. The bottom ends of the main rod 8 and the support rods 9 are both pointed ends that can be inserted into the rock and soil, thereby firmly fixing the fishbone rod while enhancing its soil retaining effect. The fishbone rod here can be fixed to the slope with the anchor tube 1 in advance, or it can be directly inserted later. Because the size of the fishbone is very small compared to the green plant area on the slope, it is convenient to insert it directly into the green plants, and it will not seriously damage the root system of the green plants.

[0037] As one of the specific implementation structures, in order to facilitate the rotation of the shaft 3, as Figure 4-5, there is a hexagonal slot at the top of the rotating shaft 3 for the main shaft of the power supply motor to be inserted, so as to drive the rotating shaft 3 to rotate quickly. A locking cover 10 is threadedly matched at the top end of the anchor barrel 1. When the locking cover 10 is tightened, its inner bottom surface contacts and contacts with the top of the rotating shaft 3 to axially press the rotating shaft 3. After the main shaft rotates a set number of times, the rotating shaft 3 is fixed. In addition, when the locking cover 10 presses the rotating shaft 3, it also rotates to the position where the first connecting ear 12 fixed on its side is opposite to the second connecting ear 13 on the side wall of the anchor barrel 1. The above two connecting ears each have a locking hole that can be coaxial at this time. The lock passes through the locking hole to lock the locking cover 10 to the top of the anchor barrel 1, so that non-managers cannot operate this protective device at will.

[0038] In this embodiment, Figure 4-5 As shown, during the specific production, it is necessary to coaxially have a disc 11 with a diameter larger than that of the anchor barrel 1 at the top end of the anchor barrel 1, and the disc 11 has a circular cavity 1101 coaxial with the center hole of the anchor barrel 1. A driven internal gear ring 14 is coaxially rotatably installed in the side wall of the circular cavity 1101, and 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 circle, the independent gear tooth 16 meshes with the driving gear 15 by one gear tooth. For example, in the above embodiment, the driving gear 15 has 30 teeth, and the driven inner gear ring 14 has 60 teeth, and the transmission ratio between the two is 0.5. Therefore, the rotating shaft 3 needs to rotate 30 times before the driving gear 15 rotates one circle, and the driven inner gear ring 14 can only rotate half a circle. Therefore, if the driven gear ring is to rotate one circle in the end, the above-mentioned rotating shaft 3 must rotate 60 times. Assuming that the diameter of the above-mentioned winding wheel 4 or the winding shaft section of the rotating shaft 3 is 20 cm, then the rotating shaft 3 rotates 60 times and can at least accommodate 37.68 m of the earth-blocking rope 2. The actual length should be larger than this value, because the diameter of the coil formed by the earth-blocking rope 2 will become larger and larger than 20 cm as the winding proceeds. Therefore, only one driving gear 15 is actually needed for speed change to be sufficient to accommodate the corresponding section of the earth-blocking rope 2. Generally speaking, the spacing between adjacent anchor barrels 1 is sufficient to be within 10 meters. Therefore, the above transmission structure design is compact and small in size, but it is an ideal structure that can meet any design requirements in construction.

[0039] In this embodiment, in order to realize the control of the rotation angle of the driven inner gear ring 14, that is, to control it to rotate within a range of less than or equal to one circle, the specific rotation angle can be as follows: Figure 4-6As shown, on the inner wall of the circular cavity 1101 located above the driven inner gear ring 14, there is a coaxial T-shaped groove 17, and a positioning slide 19 is slidably connected in the T-shaped groove 17. After the positioning slide 19 slides into place in the T-shaped groove 17, it can be fixed to the corresponding position on the T-shaped groove 17. When in use, when the driven inner gear ring 14 rotates to a set angle, a limit block 20 fixed on the driven inner gear ring 14 will inevitably come into contact with the positioning slide 19, thereby stopping the rotation. At this time, the section of the earth-blocking rope 2 originally buried in the soil between the adjacent anchor cylinders 1 is just completely received in the winding shaft section, and replaced by a new section of the earth-blocking rope 2 released from another rotating shaft. As one of the implementation details, Figure 6-7 The positioning slide 19 of this embodiment includes a vertically arranged stop bar 1904, a T-bolt and a locking nut 1903, wherein the sliding nut 18 of the T-bolt is slidably installed in the T-slot 17, and the cross section of the middle section 1901 of the T-bolt is processed into a rectangular shape. At the same time, the top of the stop bar has a rectangular hole coaxially sleeved with the middle section 1901. The two will not rotate relative to each other after being plugged in, and when the threaded section 1902 of the T-bolt is tightened by the locking nut 1903, as shown in FIG. Figure 7 The locking nut 1903 presses the side of the retaining bar 1904, thereby fixing the retaining bar 1904 on the side wall of the circular cavity 1101 so as to collide with the above-mentioned limit block 20 to realize automatic control of the storage length of the earth-blocking rope 2.
