Description

Technical Field

[0002] With the advancement of urban greening and ecological environment construction, ecological retaining walls, as a new type of slope protection structure integrating structural support and plant greening functions, have been widely used in highway slope protection, river regulation, mountain management and other projects. Plant symbiotic ecological retaining walls introduce plant planting modules on the basis of traditional retaining wall structures. They not only have good mechanical stability, but also can strengthen the soil through plant roots, while improving the environmental landscape and ecosystem.

[0003] At present, most common plant-symbiotic ecological retaining wall structures are prefabricated concrete or gabion retaining wall structures, which are equipped with a number of planting holes or planting grooves for planting herbaceous or shrubby plants with soil-fixing functions. However, as the plant growth cycle progresses, the soil in the planting holes is prone to problems such as compaction and poor ventilation, which seriously affects the normal growth of plants and even causes local vegetation to wither, affecting the ecological function and aesthetics of the entire retaining wall.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-Figure 5 As shown, a plant symbiotic ecological retaining wall system includes a retaining wall body 1 and a planting box 2, the planting box 2 is fixedly connected to the retaining wall body 1, a planting cavity 3 and a first cavity 8 are opened on the planting box 2, a linkage groove 9 is opened on the side wall of the first cavity 8, a lifting rod 7 and an L-shaped rod 11 are slidably connected to the inner wall of the first cavity 8, the lower end of the lifting rod 7 extends to the bottom of the planting box 2, a floating ball 6 is fixedly connected to the lower end of the lifting rod 7, a first limiting groove 10 is opened on the side wall of the lifting rod 7, a first permanent magnetic plate 27 is fixedly connected to the L-shaped rod 11, the L-shaped rod 11 is connected to the inner wall of the first cavity 8 through a second elastic member 28, the upper end of the L-shaped rod 11 extends above the planting box 2, and a second permanent magnetic plate 29 is fixedly connected to the inner wall of the first cavity 8; The lifting rod 7 is provided with a transmission tooth 56, and the inner wall of the first cavity 8 is rotatably connected to a rotating rod 57, and a second gear 59 is fixedly connected to the rotating rod 57, and the second gear 59 is meshed with the transmission tooth 56. A rod channel 58 is opened at one end of the rotating rod 57, and a transmission bar 60 is slidably connected to the inner wall of the rod channel 58. A threaded rod 61 is fixedly connected to the transmission bar 60, and a threaded loosening drill bit 62 is fixedly connected to the left end of the threaded rod 61. A fixing block 63 is fixedly connected to the inner wall of the linkage groove 9, and a threaded hole is opened on the fixing block 63. The threaded rod 61 is threadedly connected to the inner wall of the threaded hole, and the left end of the threaded rod 61 extends into the planting cavity 3, and the threaded loosening drill bit 62 is located in the planting cavity 3.

[0025] The steps for connecting the planting box 2 to the retaining wall 1 are as follows: first, remove the debris and loose soil on the surface of the retaining wall 1, use a measuring instrument to lay out positioning lines on the surface of the retaining wall 1, calibrate the installation position and spacing of the planting box 2, drill holes in the retaining wall 1, connect the planting box 2 to the retaining wall 1 with connectors, and finally test the stability of the planting box 2.

[0026] Embodiment 1: The planting cavity 3 is filled with soil 5 , and plants 4 are planted in the soil 5 . The plants 4 grow symbiotically on the retaining wall 1 .

[0027] When loosening the soil is not required, the horizontal section of the L-shaped rod 11 is inserted into the first limiting groove 10 to limit the lifting rod 7, and the lifting rod 7 and the floating ball 6 will not move up and down. When loosening the soil is required, the L-shaped rod 11 is pushed to overcome the elastic force of the second elastic member 28 and move rightward until the first permanent magnetic plate 27 and the second permanent magnetic plate 29 are abutted and magnetically connected, and the horizontal section of the L-shaped rod 11 releases the limit on the lifting rod 7.

[0028] The buoy 6 moves up and down with the waves of the river, thereby causing the lifting rod 7 to move up and down. The transmission tooth 56 on the lifting rod 7 drives the second gear 59 to rotate, and the second gear 59 drives the rotating rod 57 to rotate. Since the transmission bar 60 is in the shape of a rectangular parallelepiped, the rod channel 58 is also in the shape of a rectangular parallelepiped that matches the transmission bar 60. The rotation of the rotating rod 57 will drive the transmission bar 60, the threaded rod 61 and the threaded loosening drill bit 62 to rotate. Since the threaded rod 61 is threadedly connected to the threaded hole on the fixed block 63, the threaded rod 61 will drive the threaded loosening drill bit 62 to rotate and move horizontally when it rotates, so that the threaded loosening drill bit 62 loosens the soil 5, improves the air permeability and drainage of the soil 5, and facilitates better growth of the plant 4.

[0029] After loosening the soil for a period of time, the L-rod 11 is moved left to disengage the magnetic connection between the first permanent magnet plate 27 and the second permanent magnet plate 29. The horizontal section of the L-rod 11 is pressed against the right wall of the lifting rod 7 under the elastic force of the second elastic member 28. When the first limiting groove 10 on the lifting rod 7 is lifted and lowered to the same level as the horizontal section of the L-rod 11, the horizontal section of the L-rod 11 is inserted into the first limiting groove 10 under the elastic force of the second elastic member 28, thereby limiting the lifting rod 7 and stopping loosening the soil.

[0030] In this embodiment, only by moving the L-shaped rod 11, the threaded loosening drill bit 62 can be driven indirectly by the wave force to rotate and move horizontally left and right to loosen the soil 5, so that the soil 5 can maintain good air permeability and looseness, which is conducive to the smooth growth of the plants 4. There is no need for workers to carry tools and lean out of the shore for a long time to loosen the soil 5 in the planting box 2 as in traditional technologies, which reduces the difficulty of loosening the soil and improves the safety of operation.

[0033] According to an optional embodiment of the present invention, a meshing cavity 20 is provided on the planting box 2, a second annular groove 54 is provided on the inner wall of the planting cavity 3, a gear ring 21 is rotatably connected to the inner wall of the second annular groove 54, a first annular groove 22 is provided on the top wall of the gear ring 21, the bottom wall of the first annular groove 22 is connected to the bottom wall of the gear ring 21 through the liquid outlet channel 23, the gear ring 21 extends into the meshing cavity 20, a worm 18 is rotatably connected to the bottom wall of the meshing cavity 20, and a first annular groove 22 is provided on the top wall of the gear ring 21. A gear 19, the first gear 19 and the gear ring 21 are meshed, the lower end of the worm 18 extends into the linkage groove 9, the inner wall of the linkage groove 9 is fixedly connected with a one-way bearing 17, the one-way bearing 17 is rotatably connected with a linkage shaft 14, the linkage shaft 14 is fixedly connected with a worm wheel 15 and a friction wheel 16, the worm wheel 15 and the worm 18 are meshed, the lifting rod 7 is connected with a friction plate 12 through a first elastic member 13, the friction plate 12 is slidably connected to the inner wall of the linkage groove 9, and the friction plate 12 and the friction wheel 16 are against each other.

[0034] According to an optional implementation of the present invention, a reversing wheel assembly 39 is connected to the top wall of the liquid tank 33 , and the floating block 37 is turned by the reversing wheel assembly 39 .

[0035] According to an optional embodiment of the present invention, the upper end of the lifting rod 7 is fixedly connected to a limit block 24 , the first wedge block 25 is fixedly connected to the top wall of the limit block 24 , and the inner wall of the first cavity 8 is fixedly connected to a supporting member 26 .

[0036] According to an optional implementation of the present invention, the friction plate 12 is provided with a first rough friction surface, and the friction wheel 16 is provided with a second rough friction surface, and the first rough friction surface and the second rough friction surface are opposed to each other.

[0037] According to an optional implementation of the present invention, the distances between every two adjacent second permanent magnet blocks 51 are equal.

[0038] According to an optional implementation of the present invention, the fourth permanent magnet block 53 is located above the third permanent magnet block 52 .

[0039] Embodiment 2: On the basis of Example 1, when the horizontal section of the L-shaped rod 11 is inserted into the first limit groove 10, the third permanent magnet block 52 magnetically attracts one of the second permanent magnet blocks 51, so that all the second permanent magnet blocks 51 and the connecting rod 50 move right to the right limit position, and the second permanent magnet block 51 does not magnetically repel the first permanent magnet block 46.

[0040] After the L-shaped rod 11 moves to the right, the third permanent magnet 52 will move to the right, and the second permanent magnet 51 will lose the magnetic attraction of the third permanent magnet 52, and the second permanent magnet 51 will maintain the current position. When the lifting rod 7 moves up and down, the first wedge block 25 will push the second wedge block 32 to overcome the elastic force of the fifth elastic member 55 and move to the left, thereby causing the valve plate 30 to move to the left. When the plate hole 31 and the liquid transfer channel 34 and the first annular groove 22 are connected, the nutrient solution 36 passes through the liquid transfer channel 34 and the plate hole 31 under its own gravity and enters the first annular groove 22. Then, the nutrient solution 36 in the first annular groove 22 passes through the liquid outlet channel 23 and falls into the soil 5, thereby replenishing nutrients to the soil 5 and allowing the plant 4 to grow more smoothly.

[0041] When the lifting rod 7 moves downward, since the friction plate 12 and the friction wheel 16 are against each other, that is, the first rough friction surface and the second rough friction surface are against each other, the friction plate 12 drives the friction wheel 16 to rotate through the friction force, and the friction wheel 16 drives the linkage shaft 14, the worm wheel 15, the worm 18, the first gear 19, the gear ring 21 and the liquid outlet channel 23 to rotate. The rotation of the liquid outlet channel 23 causes the nutrient solution 36 to drip into the soil 5 from different angles, ensuring that the nutrients are evenly distributed in the soil 5, reducing the local concentration of nutrients being too high or too low, avoiding the waste and loss of nutrients, and preventing the local humidity of the soil 5 from being too high, thereby destroying the aggregate structure of the soil 5 and affecting the air permeability and water permeability of the soil 5.

[0042] When the lifting rod 7 moves upward, since the one-way bearing 17 limits the linkage shaft 14 to rotate in only one direction, the friction wheel 16 will not be driven by the friction plate 12, and the friction plate 12 can move upward smoothly without being limited by the friction wheel 16.

[0043] When the liquid level of the nutrient solution 36 in the liquid chamber 35 drops, the floating block 37 is driven to move downward, and the floating block 37 pulls the transmission plate 40 upward through the pull line 38. When one of the second permanent magnet blocks 51 moves up to the same horizontal plane as the fourth permanent magnet block 53, the fourth permanent magnet block 53 magnetically repels the second permanent magnet block 51, so that all the second permanent magnet blocks 51 and the connecting rod 50 move left to the left limit position, the liquid level of the nutrient solution 36 continues to drop, and the transmission plate 40 continues to move upward. When another second permanent magnet block 51 moves to the same horizontal plane as the first permanent magnet block 46, the second permanent magnet block 51 repel the first permanent magnet block 46. The fourth wedge block 45 overcomes the elastic force of the fourth elastic member 47 and moves leftward, thereby pushing the third wedge block 43 to overcome the elastic force of the third elastic member 44 and move downward. The lower end of the third wedge block 43 abuts against the top wall of the valve plate 30. When the second limiting groove 41 moves below the third wedge block 43, the third wedge block 43 is inserted into the second limiting groove 41 to limit the valve plate 30. At this time, the valve plate 30 blocks the liquid transmission channel 34, so that the nutrient solution 36 stops falling into the soil 5, thereby preventing excessive addition of the nutrient solution 36 from causing waste and causing problems such as salinization of the soil 5, excessive humidity, and microbial imbalance.

[0044] When the L-shaped rod 11 moves to the left to limit the lifting rod 7, the third permanent magnet block 52 will move to the left, thereby magnetically attracting one of the second permanent magnet blocks 51 to the right limit position. After the first permanent magnet block 46 loses the magnetic repulsion of the second permanent magnet block 51, the fourth wedge block 45 moves to the right and resets under the elastic force of the fourth elastic member 47, and the third wedge block 43 moves up and resets under the elastic force of the third elastic member 44. The third wedge block 43 is separated from the second limiting groove 41 to release the limit on the valve plate 30, so that the valve plate 30 can move when the L-shaped rod 11 moves to the left next time. The equidistant arrangement between adjacent second permanent magnet blocks 51 can ensure that each time the L-shaped rod 11 moves to the right, an appropriate and equal amount of nutrient solution 36 can be added to the soil 5, and the amount of nutrient addition can be automatically controlled without manual control.

[0045] According to an optional embodiment of the present invention, the material of the float 6 includes PVC, the float 6 is a hollow structure, and the lifting rod 7 is coated with a waterproof and anti-corrosion coating. PVC has good acid and alkali resistance, grease resistance, water resistance and other properties, is low in price, has large and stable buoyancy, and is suitable for being used as the material of the float 6. The waterproof and anti-corrosion coating can prevent the river water from corroding the lifting rod 7.
