Description

Technical Field

[0001] The invention relates to the technical field of slope protection, and in particular to a slope protection ecological restoration device and method with adjustable drainage. Background Art

[0002] Slope protection ecological restoration refers to the construction of a comprehensive slope protection system in water conservancy projects through plants or a combination of plants and auxiliary structures. This system can not only maintain water and soil and prevent soil erosion, but also repair and improve the ecological environment, maintain ecological balance, and improve the landscape effect. Specifically, slope protection ecological restoration technology integrates the basic knowledge of engineering mechanics, soil science, ecology and botany, supports slopes or side slopes, and forms a comprehensive slope protection system composed of plants or engineering and plants. The purpose of this technology is to meet the needs of engineering projects such as flood control, drainage and shipping, while fully considering the ecological effects, and transforming the river embankment from a concrete building in the past into a natural-like slope protection suitable for biological growth, where water and soil, water and plants or organisms conserve each other. The main functions of ecological slope protection include deep root anchoring of vegetation, shallow root reinforcement, prevention of soil erosion, and improvement of environmental functions, such as restoring the damaged ecological environment, reducing noise, reducing light pollution, ensuring driving safety, promoting the degradation of organic pollutants, purifying the air, and regulating the microclimate.

[0003] After searching, it was found that there were problems with the use of slope protection in the prior art. Since there was a plant planting area on the side of the slope protection, rainwater fell on the slope protection on rainy days, and the soil and plants on it would absorb the rainwater, but the amount of rainwater might be greater than the amount that the soil and plants could absorb, resulting in the soil and plant roots being soaked in water, the soil gradually becoming loose, and prone to soil erosion. The effects of traditional densely planted plants and drainage channels were unstable. Secondly, on rainy days, runoff might be generated on the side of the slope protection, and part of the runoff might move laterally due to the unevenness of the soil and the obstruction of the plants. The lateral runoff might move laterally on the slope protection for a distance and then move downward. The lateral runoff stayed on the slope protection longer than the runoff that moved directly downward, resulting in the lateral runoff scouring the soil surface, causing soil particles to be carried away, forming erosion gullies, aggravating soil erosion, and possibly destroying the soil structure, dispersing soil or soil particles, aggravating soil erosion, and affecting the use of the slope protection. Therefore, based on the above search and in combination with the prior art, a slope protection ecological restoration device and method with adjustable drainage is proposed to solve the above problems.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0037] In a typical implementation of this application, please refer to Figures 1 to 12, a drainage-adjustable slope protection ecological restoration device and method, comprising a slope protection body 1, a water-permeable groove 26 is provided on one side of the slope protection body 1, and excess rainwater will enter the inside of the water-permeable groove 26, and a slope protection side plate 2 is installed inside the water-permeable groove 26, and the slope protection side plate 2 is cast by concrete and steel bars, and a plurality of planting grooves 32 for planting are provided on one side of the slope protection side plate 2, and the planting grooves 32 are grooves left in the process of casting the slope protection side plate 2. By putting soil into the planting grooves 32, plants can be planted in the planting grooves 32, and a drainage ditch 3 for drainage is provided on one side of the slope protection side plate 2; a grille plate 4 is movably sleeved in the inside of the drainage ditch 3 to prevent debris from entering the drainage ditch 3; a connecting groove 25 is provided on one side of the slope protection body 1 to communicate with the drainage ditch 3; a drainage adjustment mechanism 7 is provided on one side of the slope protection side plate 2 to adjust the drainage on the slope protection side plate 2;

[0038] The drainage regulating mechanism 7 includes a water flow trough 8, which is provided on one side of the slope protection side plate 2. A plurality of support grooves 9 are provided on one side of the slope protection side plate 2. The support grooves 9 are inclined upward and communicated with the water flow trough 8. The water flow trough 8 and the plurality of support grooves 9 constitute a tree-like drainage net. A plurality of support seats 24 are fixedly installed inside the permeable trough 26. The support seats 24 are U-shaped structures. The slope protection side plate 2 can be supported by the plurality of support seats 24. A plurality of seepage holes 36 for water seepage are provided on one side of the inner side of the planting trough 32. A permeable net 33 for blocking soil is fixedly sleeved inside the seepage hole 36.

[0039] Among them, the permeable net 33 is made of 15KN polyester non-woven fabric. This material has the characteristics of high strength, anti-aging, water permeability and corrosion resistance, and is suitable for river slope protection projects. Its internal structure has a certain porosity to ensure that water can penetrate smoothly and prevent the accumulation of soil and water, which is beneficial to the drainage and anti-seepage functions of the river.

[0040] A plurality of connecting pipes 27 are buried inside the slope protection body 1. The connecting pipes 27 are buried therein during the pouring process of the slope protection body 1. The connecting pipes 27 are connected to the drainage ditch 3. The connecting pipes 27 are U-shaped structures for conveying water inside the permeable groove 26 to the inside of the drainage ditch 3.

[0041] When it rains, rain falls on the soil in the planting groove 32 on the slope protection side plate 2, and the soil and plants inside the planting groove 32 absorb water. The excess water penetrates into the inside of the permeable groove 26 through the permeable net 33 and then enters the inside of the drainage ditch 3 through the multiple connecting pipes 27.

[0042] At the same time, runoff will be formed on the slope protection side plate 2. The runoff will move vertically on the slope protection side plate 2 and directly enter the multiple support grooves 9. The runoff flowing horizontally will also meet the inclined support grooves 9 and enter them, shortening the flow path of the horizontal runoff on the slope protection side plate 2, reducing soil and water loss on the slope protection side plate 2, and the runoff will enter the multiple support grooves 9 and then flow into the water trough 8 from the support grooves 9 and finally be discharged;

[0043] The drainage adjustment mechanism 7 also includes a plurality of support blocks 28, one side of the support blocks 28 is fixedly mounted on one side of the slope protection side plate 2, one side of the support block 28 is rotatably connected to a cover plate 29 through a rotating shaft, and the cover plate 29 covers the support groove 9 to prevent dead branches and leaves of plants from blocking the support groove 9. A plurality of mounting blocks 30 are fixedly mounted on both sides of the slope protection body 1, one end of the cover plate 29 is fixedly mounted with a connecting shaft 38, and one side of the mounting block 30 is fixedly mounted with a mounting box 39, and one end of the connecting shaft 38 passes through the mounting block 30 and the mounting box 39 and extends to the mounting box 39. On the outside, one end of the connecting shaft 38 passes through the mounting block 30 and the mounting box 39 and a winding disk 40 is fixedly installed on one end. A spring 45 is sleeved on the outer circumferential wall of the connecting shaft 38. One end of the spring 45 is fixedly connected to the outer circumferential wall of the connecting shaft 38. The other end of the spring 45 is fixedly connected to the inner circumferential wall of the mounting box 39. A water accumulation box 31 is slidably connected to one side of the mounting block 30. A steel wire rope 60 is wound around the outer circumferential wall of the winding disk 40. A top block 41 is fixedly installed on one side of the inner side of the water accumulation box 31. One end of the steel wire rope 60 is fixedly connected to the top surface of the top block 41.

[0044] In the initial state, the cover plate 29 blocks the support groove 9 to prevent dead plants from entering the support groove 9. When it rains, some rainwater will fall into the inside of the water accumulation box 31. When the rainwater inside the water accumulation box 31 reaches a certain weight, the water accumulation box 31 moves downward due to the weight, causing the steel wire rope 60 to move downward. The downward movement of the steel wire rope 60 causes the winding disk 40 to drive the connecting shaft 38 to rotate. The rotation of the connecting shaft 38 drives the cover plate 29 to rotate. After the cover plate 29 rotates outward, it is convenient for runoff to enter the support groove 9.

[0045] The inner wall of the water accumulation box 31 is slidably connected with a sealing plate 37, the inner bottom surface of the water accumulation box 31 is slidably connected with a movable block 46, racks 49 are symmetrically installed on both sides of the movable block 46, and a gear 50 is meshed and connected on the rack 49. Two bearing seats 61 are fixedly installed on the inner bottom surface of the water accumulation box 31, and one end of the gear 50 is rotatably connected to the bearing seat 61 through a rotating shaft, and the bearing seat 61 can support the gear 50;

[0046] A connecting rod 2 59 is fixedly installed on one side of the gear 1 50 through a pin, a slide bar 57 is fixedly installed on the bottom surface of the sealing plate 37, a limiting block 56 is arranged on the top surface of the movable block 46, a slide groove 58 is provided on the top surface of the limiting block 56, the slide groove 58 is slidably connected with the slide bar 57, the slide bar 57 and the slide groove 58 are both T-shaped structures, and the two can limit the movement of the limiting block 56 by cooperation, and racks 2 55 are symmetrically installed on both sides of the limiting block 56, and gears 2 54 are meshed and connected on the racks 2 55, and connecting rods 1 53 are fixedly installed on both sides of the gear 2 54 through pins, and one end of the connecting rod 1 53 is rotatably connected with one end of the connecting rod 2 59 through a rotating shaft, and the racks 2 55, gears 2 54, connecting rods 1 53 and connecting rods 2 59 on both sides of the limiting block 56 are axially symmetrical with each other;

[0047] A screw rod 48 is rotatably connected to the inside of the water collection box 31 through a bearing, and the screw rod 48 is threadedly connected to the movable block 46. One end of the screw rod 48 passes through one side of the water collection box 31 and a knob 42 is fixedly installed on one end. A limiting rod 47 is fixedly installed inside the water collection box 31, and the limiting rod 47 is slidably connected to the movable block 46. The movement of the movable block 46 can be limited by the limiting rod 47.

[0048] In addition, by rotating the knob 42, the screw rod 48 is driven to rotate, and the rotation of the screw rod 48 causes the movable block 46 to drive the rack 1 49 to move, and the movement of the two racks 1 49 causes the gear 1 50 to rotate, and the rotation of the gear 1 50 drives the connecting rod 2 59 and the connecting rod 1 53 to rotate, and the connecting rod 1 53 rotates so that the gear 2 54 drives the limiting block 56 to move through the rack 2 55, and the connecting rod 2 59 and the connecting rod 1 53 rotate upward, which also causes the sealing plate 37 to move outward, and the outward movement of the sealing plate 37 reduces the internal volume of the water accumulation box 31, thereby changing the weight of the water accumulation box 31, and the change in the weight of the water accumulation box 31 causes the rotation angle of the cover plate 29 to change, and then the angle of the cover plate 29 is adjusted according to demand;

[0049] By adopting the above technical solution, through the slope protection body 1, the staff can lay soil and plant plants inside the planting groove 32 on the slope protection side plate 2 on the side of the slope protection body 1. In the initial state, since there is no rainwater inside the water accumulation box 31, the cover plate 29 will cover the upper part of the support groove 9 to prevent the dead branches and leaves of the plants on the planting groove 32 from entering the support groove 9 and blocking the support groove 9;

[0050] On rainy days, rainwater will fall on the slope protection side plate 2, and part of the rainwater will be absorbed by the plants and soil inside the planting groove 32. At this time, due to the blocking of the cover plate 29, it is difficult for rainwater to enter the inside of the support groove 9. The soil and plants inside the planting groove 32 can absorb limited rainwater. The excess rainwater inside the planting groove 32 will enter the inside of the permeable groove 26 through the permeable net 33. The rainwater entering the permeable groove 26 will enter the inside of the drainage ditch 3 through the multiple connecting pipes 27.

[0051] At the same time, when the precipitation time is long or the rainfall per unit time is large, runoff will appear on the slope protection side plate 2. At the same time, as the overall precipitation increases, rainwater is continuously accumulated inside the water accumulation box 31. The weight of the rainwater causes the water accumulation box 31 to move downward. At this time, the rainfall reaches a certain amount and the soil and plants inside the planting groove 32 have fully absorbed the rainwater.

[0052] The water box 31 moves downward due to its weight, causing the wire rope 60 to move downward. The downward movement of the wire rope 60 releases the remaining wire rope 60 of the winding disk 40 and causes the winding disk 40 to rotate. The rotation of the winding disk 40 drives the connecting shaft 38 to rotate and causes the mainspring 45 to reel up. The rotation of the connecting shaft 38 drives the cover plate 29 to rotate so that the cover plate 29 rotates around the support block 28. At this time, the cover plate 29 rotates outward. After the cover plate 29 rotates outward, the support slot 9 is opened.

[0053] During the precipitation period or when the rainfall per unit time is large, runoff will appear on the slope protection side plate 2. The vertical runoff will directly enter the interior of the support groove 9 and then enter the interior of the water flow groove 8 from the support groove 9, while the lateral runoff will meet the inclined support groove 9 after moving horizontally on the slope protection side plate 2, shortening the moving distance of the lateral runoff on the slope protection side plate 2, preventing the soil inside the planting groove 32 from forming gullies due to the flow of lateral runoff, and reducing soil and water loss;

[0054] In addition, the staff rotates the knob 42, and the rotation of the knob 42 causes the movable block 46 to drive the two racks 49 to move along the screw rod 48. The movement of the rack 49 causes the gear 50 to rotate around the bearing seat 61. The rotation of the gear 50 drives the connecting rod 2 59 to rotate. The rotation of the connecting rod 2 59 drives the connecting rod 1 53 to rotate. The rotation of the connecting rod 1 53 drives the gear 2 54 to rotate. The rotation of the gear 2 54 causes the rack 2 55 on the slide 58 to move. The movement of the rack 2 55 causes the limiting block 56 to move. The movement of the limiting block 56 moves along the slide bar 57 on the bottom surface of the sealing plate 37. The slide bar 57 and the slide groove 58 cooperate with each other to limit the movement of the limiting block 56. The rotation of the connecting rod 2 59 and the connecting rod 1 53 also makes the limiting block 56 drive the sealing plate 37 to move upward. After the sealing plate 37 moves upward, the volume inside the water accumulation box 31 changes. The change in the volume of the water accumulation box 31 changes the weight of the water accumulation box 31 in rainy days. The smaller the weight of the water accumulation box 31, the smaller the force applied by the water accumulation box 31 to the wire rope 60. The smaller the force on the wire rope 60, the smaller the winding amplitude of the spring 45. The small winding amplitude of the spring 45 makes the rotation angle of the cover plate 29 small.

[0055] In the first case, when the cover plate 29 is rotated outward at a small angle, rainwater is difficult to directly enter the interior of the support groove 9, but enters the planting groove 32 through the inclined cover plate 29. At this time, only runoff and a small amount of rainwater enter the interior of the support groove 9, and the drainage speed is relatively slow; in the second case, when the cover plate 29 is rotated outward at a large angle and is perpendicular to the slope protection side plate 2, rainwater directly enters the internal runoff of the support groove 9 and also enters the interior of the support groove 9, which speeds up the drainage. The first case is suitable for when there is no rainfall for a long time and the soil is dry and the plants are short of water. The second case is suitable for when the soil is relatively moist and the plants are not short of water, which is convenient for adjusting the drainage;

[0056] During this process, in the initial state, the cover plate 29 can shield the support groove 9 to prevent the support groove 9 from being blocked and allow rainwater to be absorbed by the soil and plants inside the planting groove 32 first. At this time, the excess rainwater will enter the inside of the permeable groove 26 through the permeable net 33 and then enter the inside of the drainage ditch 3 through the multiple connecting pipes 27;

[0057] The tree-like drainage network composed of multiple support grooves 9 and water flow grooves 8 can effectively shorten the movement path of lateral runoff on the slope protection side plate 2 and reduce soil erosion; the movable block 46 is driven to move by the cooperation of the knob 42 and the screw rod 48, and then the sealing plate 37 is moved upward by the connecting rod 2 59 and the connecting rod 1 53 to change the volume inside the water accumulation box 31. The angle of rotation of the cover plate 29 is changed by the volume change. The adjustment of the rotation angle of the cover plate 29 controls whether rainwater directly enters the support groove 9, so that the soil and plants inside the planting groove 32 increase or decrease the absorption of rainwater, and the drainage speed is controlled, thereby adjusting the drainage on the slope protection side plate 2 on the side of the slope protection body 1, so as to achieve the drainage adjustment effect of the slope protection body 1 and the slope protection side plate 2, which is helpful to make the slope protection body 1 and the slope protection side plate 2 in water conservancy projects;

[0058] A water tank 6 for storing water is fixedly installed on the bottom surface of the slope protection body 1, and a water inlet pipe 14 is fixedly installed on the top surface of the water tank 6. The water inlet pipe 14 penetrates the slope protection body 1 and extends to the inside of the drainage ditch 3. A one-way valve 15 is fixedly installed inside the water inlet pipe 14. The water inside the drainage ditch 3 enters the inside of the water tank 6 in one direction through the one-way valve 15. A water outlet valve 16 for discharging water is fixedly installed on one side of the water tank 6. A connecting pipe 17 is fixedly sleeved on the inner circular wall surface of the water outlet valve 16, and a flange is fixedly sleeved on the outer circular wall surface of the connecting pipe 17. The external pipeline can be connected to the connecting pipe 17 by using the flange;

[0059] The water inside the drainage ditch 3 enters the water storage tank 6 through the one-way valve 15 and the water inlet pipe 14 for storage. The staff connects the pipe with the connecting pipe 17 to use the water stored in the water storage tank 6 to irrigate the plants.

[0060] Specifically, through the slope protection body 1, excess rainwater on the slope protection side plate 2 on the side of the slope protection body 1 will enter the interior of the drainage ditch 3 through the water flow groove 8 and the connecting groove 25. On rainy days, the water inside the drainage ditch 3 will flow through the one-way valve 15 and the water inlet pipe 14 into the water storage tank 6 for storage. During the installation of the slope protection body 1, the staff will connect the pipeline with the connecting pipe 17 through a flange. When watering the plants on the slope protection side plate 2, the water outlet valve 16 will be opened to allow the water stored in the water storage tank 6 to pass through the connecting pipe 17 and the pipeline to irrigate the plants on the slope protection side plate 2, thereby storing and utilizing the rainwater.

[0061] As a preferred implementation in this embodiment, please refer to Figures 1 to 10 A slide rail 43 for supporting the movement of the water accumulation box 31 is fixedly installed on one side of the mounting block 30, and a slide column 44 is fixedly installed on one side of the water accumulation box 31. The slide column 44 is slidably connected to the slide rail 43. The movement of the water accumulation box 31 drives the slide column 44 to move on the slide rail 43. The slide rail 43 and the slide column 44 cooperate to limit the movement of the water accumulation box 31. Support bars 13 are fixedly installed on both sides of the interior of the drainage ditch 3. The two support bars 13 can support the grille plate 4. Two positioning columns 11 are fixedly installed on the top surface of the support bar 13. A plurality of positioning columns 11 are provided on the top surface of the grille plate 4. The positioning columns 11 are movably sleeved with the positioning holes 10. Bolts 12 for limiting are threadedly connected on both sides of the positioning columns 11.

[0062] Specifically, through the water accumulation box 31, the movement of the water accumulation box 31 will drive the slide post 44 to move along the slide rail 43. The slide rail 43 and the slide post 44 can cooperate to support the movement of the water accumulation box 31 and limit the movement of the water accumulation box 31, so as to achieve the limiting effect of the water accumulation box 31. The staff places the grille plate 4 on the two support bars 13 inside the drain ditch 3 so that the positioning post 11 enters the inside of the positioning hole 10. The staff installs the bolts 12 on both sides of the positioning post 11. The positioning hole 10 and the positioning post 11 can cooperate to position the grille plate 4, and the bolts 12 on both sides of the positioning post 11 can limit the grille plate 4 to prevent the grille plate 4 from tilting upward.

[0063] Two connecting pipes 51 are fixedly installed on the inner bottom surface of the water accumulation box 31. A positioning strip 52 is slidably connected inside the connecting pipe 51. The top surface of the positioning strip 52 is fixedly connected to the bottom surface of the sealing plate 37. The movement of the sealing plate 37 will drive the positioning strip 52 to move inside the connecting pipe 51. The connecting pipe 51 and the positioning strip 52 cooperate to support the movement of the sealing plate 37.

[0064] Specifically, the movement of the sealing plate 37 drives the positioning bar 52 to move inside the second connecting pipe 51. The second connecting pipe 51 and the positioning bar 52 cooperate to limit the movement of the sealing plate 37, thereby preventing the sealing plate 37 from tilting during the movement and improving the stability of the sealing plate 37 during the movement.

[0065] A plurality of support plates 34 are fixedly installed inside the planting trough 32, and a plurality of connection holes 35 for water permeability are opened on one side of the support plate 34. The support plate 34 can block the soil inside the planting trough 32, and the plurality of connection holes 35 on the support plate 34 can allow the water falling inside the planting trough 32 to flow;

[0066] Specifically, through the slope protection side plate 2, the staff will lay the soil between the multiple support plates 34 inside the planting groove 32 on the slope protection side plate 2 and then plant the plants therein. The support plates 34 can block the soil inside the planting groove 32 to prevent the soil from loosening. Secondly, the rainwater falling inside the planting groove 32 will also flow through the connection holes 35 on the support plates 34 to prevent the rainwater from staying somewhere on the planting groove 32.

[0067] The filter screen 5 for blocking debris is slidably connected inside the connection groove 25, two positioning frames 18 are fixedly installed on the side of the slope protection body 1, and two connection blocks 19 for positioning are fixedly installed on the inner top surface of the filter screen 5. The connection blocks 19 are slidably connected with the positioning frames 18. The filter screen 5 can block the debris inside the water flow trough 8. The positioning frames 18 and the connection blocks 19 cooperate to position the filter screen 5.

[0068] Specifically, through the slope protection body 1, rainwater on the slope protection side plate 2 on the side of the slope protection body 1 will enter the interior of the drainage ditch 3 through the water flow groove 8 and the connecting groove 25. The filter 5 can filter the rainwater to prevent debris from entering the interior of the drainage ditch 3. After long-term use, some debris may be stuck in the filter 5. The staff moves the filter 5 upward to separate the connecting block 19 from the positioning frame 18. After cleaning the debris stuck on the filter 5, the staff resets the filter 5 to make the connecting block 19 on the filter 5 enter the interior of the positioning frame 18, thereby positioning the filter 5 to prevent the filter 5 from tilting.

[0069] A plurality of fixing blocks 22 are fixedly installed on the top surface of the slope protection body 1, and a support frame 21 is rotatably connected between every two fixing blocks 22 through a rotating shaft. The support frame 21 is elastically connected to the top surface of the slope protection body 1 through a spring 23, and the spring 23 is installed on the bottom surface of the support frame 21. One end of the spring 23 is fixedly connected to the top surface of the slope protection body 1. The spring 23 can provide a reset force for the support frame 21. A clamping groove 20 is provided on both sides of the filter screen 5, and one end of the support frame 21 is clamped with the clamping groove 20;

[0070] The support frame 21 is squeezed to rotate downward around the fixing block 22 and one end of the support frame 21 is separated from the clamping groove 20, so that the filter screen 5 can be removed and the debris stuck in the holes of the filter screen 5 can be cleaned;

[0071] Specifically, through the set filter 5, before the staff cleans the filter 5, the staff presses the support frame 21 so that the support frame 21 rotates outward around the two fixed blocks 22 and the spring 23 is compressed. The support frame 21 rotates outward so that one end of the support frame 21 is separated from the clamping groove 20 on the filter 5. Then the filter 5 can be removed. Under normal conditions, the support frame 21 can clamp the filter 5 to prevent the filter 5 from falling off.

[0072] Working principle: through the slope protection body 1, rainwater falls into the soil in the planting groove 32 on the slope protection side plate 2 on the side of the slope protection body 1 on rainy days, the soil and plants inside the planting groove 32 will absorb water, and the excess water will penetrate into the inside of the permeable groove 26 through the permeable net 33 and then enter the inside of the drainage ditch 3 through multiple connecting pipes 27;

[0073] In the initial state, the cover plate 29 blocks the support groove 9 to prevent dead plants from entering the support groove 9. When it rains, some rainwater will fall into the inside of the water collection box 31. When the rainwater inside the water collection box 31 reaches a certain weight, the water collection box 31 moves downward due to the weight, causing the steel wire rope 60 to move downward. The steel wire rope 60 moves downward, causing the winding disk 40 to drive the connecting shaft 38 to rotate. The rotation of the connecting shaft 38 drives the cover plate 29 to rotate. After the cover plate 29 rotates outward, it is convenient for runoff to enter the support groove 9.

[0074] As a result, the runoff moves vertically on the slope protection side plate 2 and directly enters the multiple support grooves 9. The runoff flowing horizontally will also meet the inclined support grooves 9 and enter them, shortening the flow path of the horizontal runoff on the slope protection side plate 2, reducing soil and water loss on the slope protection side plate 2, and the runoff enters the multiple support grooves 9 and then flows into the water flow groove 8 from the support groove 9 and is finally discharged.

[0075] At the same time, the knob 42 is turned to drive the screw rod 48 to rotate, and the rotation of the screw rod 48 causes the movable block 46 to drive the rack 1 49 to move, and the movement of the two racks 1 49 causes the gear 1 50 to rotate, and the rotation of the gear 1 50 drives the connecting rod 2 59 and the connecting rod 1 53 to rotate, and the connecting rod 1 53 rotates so that the gear 2 54 drives the limiting block 56 to move through the rack 2 55, and the connecting rod 2 59 and the connecting rod 1 53 rotate upward, which also causes the sealing plate 37 to move outward, and the outward movement of the sealing plate 37 reduces the internal volume of the water accumulation box 31, thereby changing the weight of the water accumulation box 31, and the change in the weight of the water accumulation box 31 causes the rotation angle of the cover plate 29 to change, and then the angle of the cover plate 29 is adjusted according to demand, thereby adjusting the drainage speed;

[0076] In addition, the water inside the drainage ditch 3 enters the water storage tank 6 through the one-way valve 15 and the water inlet pipe 14 for storage. The staff connects the pipe with the connecting pipe 17 to use the water stored in the water storage tank 6 to irrigate the plants.

[0077] Finally, the filter 5 can block the debris inside the water trough 8 by squeezing the support frame 21 so that the support frame 21 rotates downward around the fixed block 22 and separates one end of the support frame 21 from the snap-in groove 20, thereby removing the filter 5 and cleaning the debris stuck in the holes of the filter 5.

[0078] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
