Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, and particularly to a slope ecological restoration slope protection device and method. Background Art

[0002] With the rapid development of infrastructure construction, there are problems of uncoordinated ecological environment development. Since there are many mountains in our country, a large number of slopes are often generated in engineering construction, such as mountain highway slopes, reservoir bank along-river highway slopes, etc. In order to prevent the slope from being washed by rainwater and causing landslides and collapses, it is necessary to take protective measures for the slope.

[0003] In order to solve the problem of "the slope body will be washed by rainwater", a Chinese patent with the publication number CN116971403A discloses a slope ecological restoration slope protection device, including: a fixing component, the fixing component includes a plurality of first frames, the plurality of first frames are detachably connected to each other, the first frames are located on the upper surface of the slope body, the first frames are fixedly connected to the slope body through fixing rods, and the fixing rods are inserted into the slope body; a planting component, the planting component includes a plurality of planting plates, a plurality of seed grooves are arranged on the planting plates, grass seed packets are placed in the seed grooves, the planting plates are filled with soil, and the planting plates are detachably connected in the first frames; a drainage component, the drainage component includes a drainage groove, the drainage groove is arranged between two columns of first frames, and a water retainer is arranged on the first frame, and the water retainer is communicated with the drainage groove. Although the existing technical problems are solved, there are still the following problems:

[0004] In this technical solution, when it rains, the diversion groove can block a part of the rainwater, reducing the scouring effect of the rainwater on the soil in the first space. The rainwater flows out from the flowing water holes along the diversion groove. However, if the diversion grooves are set too densely, it will block the sunlight of the soil vegetation below the diversion grooves, affecting its growth. If the diversion grooves are set too sparsely, the blocked rainwater is limited, and still cannot achieve a good effect of preventing rainwater scouring. Therefore, corresponding improvements are made to solve this problem. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention provides a slope ecological restoration slope protection device and method.

[0006] A slope ecological restoration and slope protection device proposed by the present invention includes a frame. A pair of ear seats are fixed on both sides of the frame. Ground nails for fixing the frame to the slope are inserted on the ear seats. A plurality of evenly distributed leaf plates are arranged inside the frame. Shaft columns are fixed at both ends of the leaf plates. The ends of the shaft columns pass through the frame and form a rotational connection with the frame. A water tank is slidably connected to the bottom end of the frame. The water tank is connected to the shaft column through a transmission component. Under normal conditions, the leaf plates maintain a state of forming an inclination angle with the frame, so that the soil on the slope can receive normal sunlight and does not affect the normal growth of vegetation. In rainy weather, when the amount of rain received in the water tank gradually increases, the water tank will slide downward, and then drive the shaft column and the leaf plate to rotate through the transmission component, so that the leaf plates are parallel to the surface of the frame and enclose the frame, thereby avoiding rainwater from washing away the soil.

[0007] Preferably, the transmission component includes a pair of racks. The two racks are distributed on both sides of the frame. The bottom end of the rack is fixedly connected to the water tank. A gear is fixedly sleeved on the shaft column. The rack is meshed with a plurality of gears on the same side. An elastic connection is formed between the rack and the frame. When the water tank moves, the rack is driven to move synchronously. The rack will drive the gear to rotate meshingly, and then the gear will drive the shaft column and the leaf plate to rotate synchronously.

[0008] Preferably, a guide rod is inserted through the top end of the rack. A first ear block is fixed at the bottom end of the guide rod. The first ear block is fixed on the frame. A first spring is sleeved on the guide rod. The two ends of the first spring are respectively fixedly connected to the first ear block and the rack. In this way, after the rain stops, as the rainwater in the water tank evaporates and decreases, the first spring will push the rack to move back to its original position, and the leaf plates will gradually rotate to the initial position.

[0009] Preferably, the transmission component includes multiple pairs of pulleys fixedly sleeved on the shaft columns. Two pulleys on adjacent shaft columns are connected by a belt. The adjacent two belts are arranged in a staggered manner. An elastic connection is formed between the support rod and the frame. The lowermost shaft column is connected with a rotation driving structure. When the water tank moves downward, it will drive the lowermost shaft column and the leaf plate to rotate through the rotation driving structure, and then the shaft columns will maintain synchronous rotation through the transmission cooperation of the belt and the pulley.

[0010] Preferably, the rotation driving structure includes a pair of support rods fixed at the top end of the water tank. The rear end of the support rod is rotatably connected to a first connecting rod. The other end of the first connecting rod is rotatably connected to a second connecting rod. The other end of the second connecting rod is fixedly sleeved on an adjacent shaft column. When the water tank moves, the support rod is driven to move synchronously, and then the support rod pulls the first connecting rod so that the second connecting rod drives the shaft column to rotate.

[0011] Preferably, a guide sleeve is fixed inside the support rod, a guide post is inserted into the guide sleeve, a second ear block is fixed to the bottom end of the guide post, the second ear block is fixed to the frame, a second spring is sleeved on the guide post, and both ends of the second spring are fixedly connected to the second ear block and the guide sleeve respectively. In this way, after the rain stops, as the rainwater in the water tank evaporates and decreases, the second spring will push the support rod to move back to its original position, and the leaf plate will gradually rotate to the initial position.

[0012] Preferably, the driving and rotating structure includes a pair of brackets respectively fixed on both sides of the frame. A rotating structure is provided at the end of the bracket. The rotating structure is connected with a winding drum. A pulling rope is wound around the winding drum. The free end of the pulling rope is fixedly connected to the water tank. The winding drum is fixedly sleeved on the shaft column. When the water tank moves downward, it will pull the pulling rope, and then the pulling rope will drive the winding drum to rotate. The winding drum will synchronously drive the shaft column to rotate. The shaft column can be driven to rotate in the reverse direction through the rotating structure.

[0013] Preferably, the rotating structure includes a first end cover and a second end cover that are rotatably connected together and a torsion spring. The torsion spring is installed between the first end cover and the second end cover. The first end cover is fixed on the bracket. The winding drum is fixedly sleeved on the second end cover. In this way, after the rain stops, as the rainwater in the water tank evaporates and decreases, the originally tightened torsion spring will reset due to its elasticity. In this way, it will drive the winding drum and the shaft column to rotate in the reverse direction through the second end cover, and the leaf plate will gradually rotate to the initial position.

[0014] Preferably, protective shells covering above multiple shaft columns are fixed on both sides of the frame. Third ear blocks are fixed on both sides of the frame. A connecting rod is fixed to the bottom end of the third ear block. A pair of water outlets are opened at the bottom of the water tank. The bottom end of the connecting rod passes through the water outlet and is fixed with a sealing plate capable of sealing the water outlet. The transmission components can be shielded and protected through the protective shell. When the water tank moves downward, the sealing plate will gradually close the water outlet. In this way, the water tank will continuously receive water and remain in the lowest state. When the water tank moves back to its original position, the sealing plate will expose the water outlet. In this way, the water in the water tank can be discharged through the water outlet as soon as possible, and the leaf plate can be reset as soon as possible.

[0015] The present invention also provides a using method of a slope ecological restoration and slope protection device, including the following steps:

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] Reference Figures 1-12 , a slope ecological restoration and slope protection device comprises a frame 1, a pair of ear seats 5 are fixed on both sides of the frame 1, and ground nails 6 for fixing the frame 1 to the slope are inserted on the ear seats 5, and a plurality of evenly distributed blades 2 are arranged in the frame 1, and shaft columns 3 are fixed at both ends of the blade plates 2. The ends of the shaft columns 3 pass through the frame 1 and form a rotation connection with the frame 1, and the bottom end of the frame 1 is slidably connected with a water tank 4, and the water tank 4 is connected to the shaft column 3 through a transmission assembly. Under normal circumstances, the blade plates 2 remain in a state of forming an inclination with the frame 1, so that the soil on the slope can be normally illuminated without affecting the normal growth of vegetation. In rainy weather, when the amount of rainfall in the water tank 4 gradually increases, the water tank 4 will slide downward, and then the shaft column 3 and the blade plates 2 will be driven to rotate through the transmission assembly, so that the blade plates 2 are parallel to the surface of the frame 1, and the frame 1 is closed, thereby preventing rainwater from eroding the soil.

[0042] In Example 1, the transmission assembly includes a pair of racks 8, and the two racks 8 are distributed on both sides of the frame 1. The bottom end of the rack 8 is fixedly connected to the water tank 4. A gear 7 is fixedly sleeved on the shaft column 3. The rack 8 is meshed and connected with multiple gears 7 on the same side. An elastic connection is formed between the rack 8 and the frame 1. When the water tank 4 moves, it synchronously drives the rack 8 to move, and the rack 8 will mesh and drive the gear 7 to rotate, and then the gear 7 will synchronously drive the shaft column 3 and the blade 2 to rotate.

[0043] Among them, a guide rod 10 is passed through the top of the rack 8, a first ear block 9 is fixed to the bottom of the guide rod 10, the first ear block 9 is fixed to the frame 1, a first spring 11 is sleeved on the guide rod 10, and the two ends of the first spring 11 are respectively fixedly connected to the first ear block 9 and the rack 8, so that after the rain stops, as the evaporation of rainwater in the water tank 4 decreases, the first spring 11 will push the rack 8 to reset and move, and the blade 2 will gradually rotate to the initial position.

[0044] In Embodiment 2, the transmission assembly includes multiple pairs of pulleys 12 fixedly sleeved on the shaft columns 3. A belt 13 is connected between two pulleys 12 on adjacent shaft columns 3. Adjacent belts 13 are staggeredly distributed. An elastic connection is formed between the support rod 14 and the frame 1. The lowermost shaft column 3 is connected with a rotation driving structure. When the water tank 4 moves downward, it will drive the lowermost shaft column 3 and the blade 2 to rotate through the rotation driving structure. Then, the shaft columns 3 will maintain synchronous rotation through the transmission cooperation of the belts 13 and the pulleys 12.

[0045] Among them, the rotation driving structure includes a pair of support rods 14 fixed to the top end of the water tank 4. The rear end of the support rod 14 is rotatably connected with a first connecting rod 15. The other end of the first connecting rod 15 is rotatably connected with a second connecting rod 16. The other end of the second connecting rod 16 is fixedly sleeved on an adjacent shaft column 3. When the water tank 4 moves, it drives the support rod 14 to move synchronously. Then, the support rod 14 pulls the first connecting rod 15, causing the second connecting rod 16 to drive the shaft column 3 to rotate.

[0046] Among them, a guide sleeve 17 is fixed inside the support rod 14. A guide post 19 is inserted into the guide sleeve 17. A second ear block 18 is fixed to the bottom end of the guide post 19. The second ear block 18 is fixed on the frame 1. A second spring 20 is sleeved on the guide post 19. The two ends of the second spring 20 are respectively fixedly connected with the second ear block 18 and the guide sleeve 17. In this way, after the rain stops, as the rainwater in the water tank 4 evaporates and decreases, the second spring 20 will push the support rod 14 to move back to its original position, and the blade 2 will gradually rotate to the initial position.

[0047] In Embodiment 3, the rotation driving structure includes a pair of brackets 21 respectively fixed on both sides of the frame 1. A rotary structure 22 is arranged at the end of the bracket 21. The rotary structure 22 is connected with a reel 23. A pull rope 24 is wound around the reel 23. The free end of the pull rope 24 is fixedly connected with the water tank 4. The reel 23 is fixedly sleeved on the shaft column 3. When the water tank 4 moves downward, it will pull the pull rope 24. Then, the pull rope 24 will drive the reel 23 to rotate, and the reel 23 will synchronously drive the shaft column 3 to rotate. The shaft column 3 can be driven to rotate in the reverse direction through the rotary structure 22.

[0048] Among them, the rotary structure 22 includes a first end cover 2201 and a second end cover 2202 rotatably connected together and a torsion spring 2203. The torsion spring 2203 is installed between the first end cover 2201 and the second end cover 2202. The first end cover 2201 is fixed on the bracket 21. The reel 23 is fixedly sleeved on the second end cover 2202. In this way, after the rain stops, as the rainwater in the water tank 4 evaporates and decreases, the originally tightened torsion spring 2203 will reset due to its elasticity. In this way, it will drive the reel 23 and the shaft column 3 to rotate in the reverse direction through the second end cover 2202, and the blade 2 will gradually rotate to the initial position.

[0049] Further, protective shells 29 covering the upper sides of a plurality of axle columns 3 are fixed on both sides of the frame 1. Third ear blocks 25 are fixed on both sides of the frame 1. A connecting rod 26 is fixed to the bottom end of the third ear block 25. A pair of water outlet openings 27 are formed at the bottom of the water tank 4. The bottom end of the connecting rod 26 passes through the water outlet opening 27 and is fixed with a sealing plate 28 capable of sealing the water outlet opening 27. The transmission assembly can be shielded and protected by the protective shell 29. When the water tank 4 moves downward, the sealing plate 28 will gradually seal the water outlet opening 27, so that the water tank 4 will continuously receive water and remain in the lowest state. When the water tank 4 moves back to its original position, the sealing plate 28 will expose the water outlet opening 27, so that the water in the water tank 4 can be discharged through the water outlet opening 27 as soon as possible, and thus the vane 2 can return to its original position as soon as possible.

[0050] The present invention also provides a method for using a slope ecological restoration slope protection device, which includes the following steps:

[0051] S1. Move the frame 1 to the slope body. After determining the position of the frame 1, insert the ground nails 6 into the ear seats 5 and nail them into the slope body to fix the frame 1.

[0052] S2. Under normal conditions, the vane 2 remains in a state of forming an inclination angle with the frame 1, so that the soil on the slope body can receive normal sunlight and does not affect the normal growth of vegetation.

[0053] S3. When it rains and the water volume in the water tank 4 increases, the water tank 4 will slide downward, and then drive the axle column 3 and the vane 2 to rotate through the transmission assembly, so that the vane 2 is parallel to the surface of the frame 1 to enclose the frame 1, thereby preventing rainwater from washing the soil.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
