Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration and management and soil and water conservation in the drawdown zone of rivers, lakes and reservoirs, and in particular to a soil-fixing and planting device for ecological restoration and management in the drawdown zone of rivers, lakes and reservoirs. Background Art

[0002] The drawdown zone refers to the alternating wet-dry zone formed by the seasonal rise and fall of water bodies such as rivers, lakes, and reservoirs, which causes the land in the water-land junction to be periodically submerged and exposed. Plants that grow in this area are called drawdown zone plants. Since the drawdown zone plays a very important role in soil conservation and biodiversity, it is also highly valued in ecology, environmental conservation, and urban planning. The drawdown zone of rivers, lakes, and reservoirs refers to the drawdown zone of flowing rivers, lakes, and reservoirs. The soil characteristics of this type of drawdown zone are relatively muddy due to the periodic dry-wet alternation.

[0003] In the process of ecological restoration and management of the drawdown zones of rivers, lakes and reservoirs, due to the properties of the drawdown zones themselves, not only are plants needed that can be easily planted when exposed, but they also need to be able to maintain growth when submerged. Under the premise of these aspects, medicinal plants, especially aquatic medicinal plants, can be used for ecological restoration and management of the drawdown zones of rivers, lakes and reservoirs. This can take into account economic value to increase planting enthusiasm, while taking into account water purification and soil conservation in the drawdown zones.

DETAILED DESCRIPTION

[0034] Example 1: Please refer to Figure 1-4 In an embodiment of the present invention, a soil-fixing planting device for ecological restoration and management of the drawdown zone of rivers, lakes and reservoirs includes a frame 3 and a bottom plate 4 arranged at the bottom of the frame 3, a plurality of groups of connecting rods 2 are assembled and connected on the frame 3, and the ends of the connecting rods 2 away from the frame 3 are commonly connected with a mounting plate 1, the side of the frame 3 is embedded with a side groove 31, and the two sides of the side groove 31 are symmetrically embedded with slide grooves 32, and a side plate 6 is slidably provided in the side groove 31, and protrusions that are slidably adapted to the slide groove 32 are provided on both sides of the side plate 6, and a support chain 33 is movably embedded on the side groove 31, and the end of the support chain 33 away from the side groove 31 is rotatably connected to the side plate 6, and when the end of the side plate 6 away from the protrusion approaches / moves away from the side groove 31, the connection between the support chain 33 and the side plate 6 radially approaches / moves away from the side groove 31.

[0035] During planting, based on the key technology system for multi-dimensional three-dimensional forest-grass composite ecological restoration and reconstruction of the river, lake and reservoir drawdown zone (forest and marsh system, all existing technologies), the plants planted by the device in this embodiment are mainly water-resistant trees (including but not limited to Zhongshan fir, etc.), supplemented by water-resistant herbaceous plants and aquatic plants, which have achieved remarkable results and showed good comprehensive benefits in soil and water conservation, water resistance, anti-scouring, wind resistance, water quality purification, landscape improvement, etc. In the study of the drawdown zone management in the Three Gorges, there have been precedents for planting Chinese medicinal plants in combination with the characteristics of the drawdown zone, which can not only purify water quality and conserve soil from the perspective of environmental protection, but also have certain economic value and improve the enthusiasm for planting. On this basis, the commonly used medicinal plants used in the drawdown zone include Euryale ferox, Houttuynia cordata, Alisma orientalis, Calamus, Lotus, Water chestnut, Water safflower seeds, Tripterygium wilfordii, Pollen truncatum, Ze Lan, etc. Specifically, when in use, the frame 3 is a frame-like structure, and the size of the side panels 6 and the side grooves 31 are preferably matched. The side panels 6 are usually fitted in the side grooves 31, and the protrusions are set at the upper ends of the two sides of the side panels 6, and the support chains 33 are correspondingly rotatably connected to the relatively lower sides of the side panels 6. The plants to be planted can be placed in the space between the frame 3 and the bottom plate 4, and one side of the bottom plate 4 is inserted into the soil in the drawdown zone of rivers, lakes and reservoirs. After removing the mounting plate 1 and the connecting rod 2, the frame 3 and the bottom plate 4 are used to maintain the planting stability of the plants. After the plant roots grow, the frame 3 and the bottom plate 4 are taken out. This can improve the survival rate of plant planting, and during planting, the planting stability of the plants can be better maintained, especially in the drawdown zone of rivers, lakes and reservoirs that are in a silt state or have relatively soft soil, which can better improve the planting efficiency and reduce the difficulty of maintenance; further using the setting of the side panels 6, After one side of the bottom plate 4 is sunk into the soil, the side plate 6 can be pushed downward relative to the side groove 31. One end of the side plate 6 can slide and cooperate with the protrusion and the slide groove 32 to limit the end of the side plate 6 to be located in the side groove 31, while the other end is relatively far away from the side groove 31, and the support chain 33 is extended at the same time. The support chain 33 can constrain the side plate 6 to gradually rotate from a state of fitting the side groove 31 to a state perpendicular to the side groove 31. During this state change, the side plate 6 can cooperate with the frame 3 to maintain the vertical state of the frame 3 and the bottom plate 4 relative to the soil. The side plate 6 extends into the soil in a relatively horizontal state. If the frame 3 and the bottom plate 4 want to tilt, it is necessary to overcome the pressure of the soil on the side plate 6, especially in silt and soil with greater flexibility. The side plate 6 can use the interaction force with the viscous soil to maintain the vertical state of the frame 3 and the bottom plate 4.

[0036] like Figure 2-Figure 6As shown, the side groove 31 is embedded in the edge of the outer side of the upper end of the frame 3, the end of the side panel 6 close to the protrusion is semicircular, and the end of the side panel 6 away from the protrusion is inclined. Preferably, the inclined surface is arranged on the side of the side panel 6 facing the side groove 31, and the end of the support chain 33 is rotatably connected to the inclined surface of the side panel 6. Among them, the support chain 33 includes a connecting plate 3301, two relatively parallel connecting plates 3301 form a group, and a rotating pin 3302 is rotatably connected between the two connecting plates 3301 in one group on both sides, and a connecting block 3303 is provided between the two adjacent groups of connecting plates 3301, and the rotating pins 3302 of the two adjacent groups are respectively movably passed through the two sides of the connecting block 3303. Preferably, the connecting plate 3301, the rotating pin 3302 and the connecting block 3303 can be in a coiled shape, or can be slidably embedded in the frame 3, and the connecting plate 3301, the rotating pin 3302 and the connecting block 3303 can rotate left and right relative to the side plate 6 and the side groove 31, but can provide supporting force in the up and down direction, which can constrain the side plate 6 to gradually slide downward from one end being attached to the side groove 31, and finally until the upper and lower ends of the side plate 6 gradually approach the same height in the vertical direction. This method makes it convenient for the side plate 6 to be inserted into the soil layer. The semicircular end of the side panel 6 facilitates the sliding and rotation of the side panel 6 in the side groove 31, and the inclined surface of the side panel 6 facilitates the installation of a hinge seat rotatably connected to the side panel 6 on a connecting plate 3301 at the outermost end of the multiple groups of connecting plates 3301, and there will be no impact when the side panel 6 is attached to the side groove 31.

[0037] Example 2: Please refer to Figure 1-Figure 4 In the embodiment of the present invention, a soil-fixing planting device for ecological restoration and management of the drawdown zone of rivers, lakes and reservoirs is provided. On the basis of the first embodiment, two sets of frame frames 3 together form a frame-like structure, and symmetrical connecting wing plates 34 are provided at the opposite edges of the two sets of frame frames 3. The two sets of frame frames 3 are stably assembled by assembling bolt connection pairs on the aligned connecting wing plates 34. Multiple sets of bottom plates 4 are provided at the bottom of the frame frames 3. The multiple sets of bottom plates 4 at the bottom of the two sets of frame frames 3 can be brought together to the middle to finally form a pyramid-like structure, and the free ends of the multiple sets of bottom plates 4 (the ends away from the frame frames 3) can also be relatively far away. In this way, when one end of the bottom plate 4 is in a pyramid shape, the frame 3 and the bottom plate 4 form a container with an open upper end, so that the plants to be planted can be placed therein (preferably together with the soil), and one end of the bottom plate 4 is inserted into the soil of the lakeside belt, and the bottom plate 4 is opened so that multiple groups of bottom plates 4 are relatively far apart. At this time, the connecting rod 2 can be removed from the frame 3, and the frame 3 and the bottom plate 4 are left in the soil of the lakeside belt. After the plants grow and adapt and the root system is stable, the frame 3 and the bottom plate 4 are taken out of the soil, and the bolt connection pair connecting the two groups of frames 3 is disassembled, thereby improving the survival rate of plant planting.

[0038] Among them, Figure 8 , Fig.10 , Fig.11As shown, the bottom plate 4 is preferably a thin plate in the shape of an isosceles triangle, the bottom side of the bottom plate 4 is arranged opposite to the frame 3, and a rotating shaft 41 is fixedly connected to the bottom side, the rotating shaft 41 is rotatably connected to the frame 3 through a bearing seat, the bottom plate 4 can rotate relative to the frame 3 through the rotatable connection between the rotating shaft 41 and the frame 3, and a wire wheel 42 is fixedly arranged on the outer periphery of the middle part of the rotating shaft 41, and a second traction rope 43 is arranged around the outer periphery of the wire wheel 42, one end of the second traction rope 43 is fixedly connected to the wire wheel 42, and the other end is connected to the traction assembly 5 through a limit joint 7, the limit joint 7 is embedded in the frame 3, and the traction assembly 5 is installed on the mounting plate 1. When the traction assembly 5 is driven in use, the second traction rope 43 can be pulled through the limit joint 7, thereby driving the wire wheel 42 to rotate, so that multiple groups of bottom plates 4 can be pulled and opened synchronously, and the premise of this is that a torsion spring is arranged on the outer periphery of the wire wheel 42, and the torsion spring acts to make multiple groups of bottom plates 4 relatively close.

[0039] like Figure 9-10As shown, the limit joint 7 includes a sleeve shell 71 embedded on the frame 3 and a connecting joint 74 slidably assembled in the sleeve shell 71, the end of the connecting joint 74 is connected to the sleeve shell 71 through a spring, and the end is connected and fixed to the second traction rope 43. When the connecting joint 74 slides away from the sleeve shell 71, the spring will be stretched, and a card cavity 73 is embedded in the sleeve shell 71 at the periphery of the end of the connecting joint 74 away from the second traction rope 43. Preferably, the card cavity 73 is symmetrically embedded on both sides of the connecting joint 74, and rotating grooves 75 are symmetrically embedded on both sides of the connecting joint 74 opposite to the card cavity 73. A core shaft 76 is radially fixedly provided in the connecting joint 74, and two groups of rotating card plates 77 are rotatably provided on the periphery of the core shaft 76, and the rotating card plates 77 extend from the rotating grooves 75. The end of the traction assembly 5 can be moved downwardly, and the end of the traction assembly 5 can be used to cooperate with the traction assembly 5, so that when the end of the traction assembly 5 moves upward, the connecting joint 74 can be pulled relative to the sleeve 71 to slide. In this way, the second traction rope 43 can be driven to move synchronously, and then the bottom plate 4 can be pulled and driven to rotate. This operation is simple and convenient, the traction is stable, and it is easy to assemble and disassemble. After the bottom plate 4 and the frame 3 are driven into the soil, the connecting rod 2 can be removed from the frame 3, and the cooperation between the end of the traction component 5 and the limit joint 7 can be disengaged, thereby leaving the bottom plate 4 and the frame 3 to give the plants sufficient self-growth time, so that the frame 3 and the bottom plate 4 can be removed after the plant roots are stable. This can improve the survival rate of the plants and avoid problems such as plant tipping in the mud.

[0040] Furthermore, in order to ensure that the connecting joint 74 does not rebound after the traction assembly 5 is relatively separated from the limiting joint 7, as Figure 10-11As shown, the outer periphery of the end of the sleeve 71 provided with a clamping cavity 73 is embedded with a threaded groove 72, and the outer periphery of the end of the connecting rod 2 away from the mounting plate 1 is movably sleeved with a threaded connection sleeve 21, and the threaded connection sleeve 21 is threadedly adapted to the threaded groove 72. An L-shaped cavity 78 is embedded in the sleeve 71, and piston protrusions are slidably embedded at both ends of the L-shaped cavity 78. One end of the L-shaped cavity 78 is opposite to the side of the connecting joint 74, and the other end of the L-shaped cavity 78 extends to be opposite to the threaded groove 72. Positioning members 79 are symmetrically embedded on both sides of the connecting joint 74. The positioning members 79 are composed of a limiting protrusion slidably embedded in the side of the connecting joint 74 and a spring connected between the limiting protrusion and the connecting joint 74. The limiting protrusion is adapted to the opening size of the L-shaped cavity 78. When the connecting joint 74 is not pulled, the end of the L-shaped cavity 78 is located between the positioning member 79 and the clamping cavity 73. When the connecting joint 74 is pulled and driven, the limiting protrusion in the positioning member 79 gradually approaches the L-shaped cavity 78. When the limiting protrusion is aligned with the end of the L-shaped cavity 78, the end of the limiting protrusion is pushed by the spring and extends into the L-shaped cavity 78. In this way, the relative position of the connecting joint 74 and the sleeve 71 can be limited by the limiting protrusion. At this time, the piston protrusion at one end of the L-shaped cavity 78 is pushed into the L-shaped cavity 78, and the piston protrusion at the other end will be pushed away from the L-shaped cavity 78. In order to prevent the piston protrusion from falling off the L-shaped cavity 78, the piston protrusion can be set in a "convex" shape, and the opening of the L-shaped cavity 78 is in a state of sliding adaptation with the end of the piston protrusion. If the threaded connection sleeve 21 is threadedly engaged with the end of the sleeve shell 71 and is threadedly engaged with the thread groove 72, the end of the threaded connection sleeve 21 will fit against one end of the L-shaped cavity 78. In this way, even if the positioning member 79 moves with the connecting joint 74 so that the limiting protrusion is opposite to the opening of the L-shaped cavity 78, it cannot push the piston protrusion at the opening of the L-shaped cavity 78 to move, and the connecting joint 74 cannot be limited in position with the sleeve shell 71. Only when it is necessary to remove the connecting rod 2 and the frame 3 relatively, the threaded connection sleeve 21 is twisted to disengage it from the thread groove 72 on the sleeve shell 71, so that the threaded connection sleeve 21 is no longer engaged with the end of the L-shaped cavity 78, and the limiting protrusion can push the piston protrusion at one end of the L-shaped cavity 78 to move, so that the The relative positions of the connecting joint 74 and the sleeve shell 71 are limited, so that even if the traction component 5 and the limiting joint 7 are disengaged, the second traction rope 43 can still remain in the traction state, so that after the base plate 4 is inserted into the soil, the connecting joint 74 is pulled upward by the traction component 5, thereby driving the second traction rope 43 to open the base plate 4, and after the threaded connection sleeve 21 and the threaded groove 72 are released, the threaded connection sleeve 21 no longer fits the end of the L-shaped cavity 78, and the limiting protrusion pushes the piston protrusion at one end of the L-shaped cavity 78, and the piston protrusion at the other end moves synchronously. The cooperation between the limiting protrusion and the L-shaped cavity 78 limits the relative movement of the connecting joint 74 and the sleeve shell 71, which can also facilitate the subsequent removal of the base plate 4 and the frame 3 from the soil.To release the relative position restriction of the connecting joint 74 and the sleeve 71 , it is only necessary to tighten the threaded connecting sleeve 21 onto the threaded groove 72 at the end of the sleeve 71 , and the piston protrusion at the end of the L-shaped cavity 78 can be pushed into the L-shaped cavity 78 , thereby pushing the limiting protrusion out of the L-shaped cavity 78 .

[0041] Furthermore, if Figure 7 and Fig.11As shown, the traction assembly 5 includes a pressing member assembled on the mounting plate 1 and a clamping member slidingly matched at the end of the connecting rod 2 away from the mounting plate 1. The pressing member and the clamping member are connected by transmission. The clamping member slides with the clamping cavity 73 in the limit joint 7 and is adapted to the rotating clamping plate 77. The pressing member includes multiple sets of pipe sleeves 51 fixedly connected to the mounting plate 1. A gripping rod 52 is arranged between the pipe sleeves 51. A first traction rope 53 is fixedly arranged through the middle of the gripping rod 52. The ends of the first traction rope 53 pass through the pipe sleeves 51 and slide through the multiple sets of connecting rods 2 and are connected to the clamping member. Preferably, two sets of pipe sleeves 51 are symmetrically arranged in this embodiment. After the two ends of the first traction rope 53 on the gripping rod 52 pass through the pipe sleeves 51 on both sides, each end of the first traction rope 53 is divided into two bundles and then passed into the connecting rod 2. Among them, the mounting plate 1 is a square frame structure. A handle 11 is fixedly connected and arranged on the mounting plate 1. The handle 11 is an arc-shaped member. Preferably, the pressing member is arranged below the handle 11, and the handle 11 is convenient for holding and operation. The clamping part includes a sliding gasket 54 that is slidably fitted on the end of the connecting rod 2. A clamping plate 55 is symmetrically rotatably connected to the side of the sliding gasket 54 away from the connecting rod 2. A torsion spring is connected between the clamping plate 55 and the sliding gasket 54. The torsion spring acts to move the ends of the two groups of clamping plates 55 away from the sliding gasket 54 relatively far away. A spring is connected between the side of the sliding gasket 54 close to the connecting rod 2 and the connecting rod 2. When the sliding gasket 54 is pulled into the connecting rod 2 by the first traction rope 53 driven by the grip rod 52, the spring is compressed, and the torsion spring is compressed, and the end of the clamping plate 55 can be retracted into the connecting rod 2. When the grip rod 52 is released, the sliding gasket 54 is slid to the end of the connecting rod 2 by the action of the spring, and the clamping plate 55 is no longer constrained by the opening of the connecting rod 2, and its end can rotate relatively far away. Preferably, an arc-shaped protrusion is provided on the inner side of one end of the card plate 55 away from the sliding gasket 54. When the card plate 55 extends into the card cavity 73, the arc-shaped protrusion pushes the rotating card plate 77 to rotate in the rotating groove 75. The rotating groove 75 preferably has a fan-shaped cross-section. When the rotating card plate 77 rotates to the bottom of the rotating groove 75, the card plate 55 can continue to move downward. Therefore, when the arc-shaped protrusion of the card plate 55 extends into the lower side of the rotating groove 75, the rotating card plate 77 can resume rotation after losing the suppression of the arc-shaped protrusion. Therefore, when the sliding gasket 54 and the card plate 55 are driven to move by the grip rod 52 and the first traction rope 53, the connecting joint 74 can be driven away from the housing 71 through the snap-fitting cooperation between the arc-shaped protrusion and the rotating card plate 77. At this time, the rotating card plate 77 is stuck in the upper part of the rotating groove 75 and cannot continue to rotate, and the transmission cooperation is stable.When it is necessary to remove the connecting rod 2 from the frame 3, after unscrewing the threaded connecting sleeve 21, the threaded connecting sleeve 21 can slide on the connecting rod 2, and when the grip 52 is still in the manually pressed state, the first traction rope 53 pulls the sliding gasket 54 and the card plate 55 into the connecting rod 2, and the card plate 55 moves out of the restriction of the card cavity 73. At this time, after releasing the grip 52, the sliding gasket 54 and the card plate 55 will move to the end of the connecting rod 2 under the action of the spring and the torsion spring, and the card plate 55 rotates relatively, so that the card plate 55 also breaks away from the restriction of the rotating card plate 77, so that the cooperation between the traction component 5 and the limiting joint 7 can also be automatically disengaged, and at this time the relative position of the connecting joint 74 and the sleeve shell 71 can be kept stable as mentioned above, the operation is simple and convenient, and automatic positioning can be achieved, and the transmission and release of the transmission do not require the addition of a limiting structure, but only need to utilize the cooperation of the structure itself and the assembly of the threaded connecting sleeve 21 to achieve it.
