Description

Technical Field

[0001] The invention relates to the technical field of water body ecological restoration and submerged plant planting, and in particular to a planting device for submerged plant posture control and orientation. Background Art

[0002] Submerged plants play a vital role in aquatic ecosystems. They can absorb nutrients from the water, inhibit algae growth, improve water transparency, and provide habitats and food sources for aquatic organisms. Therefore, how to achieve efficient and rapid planting of submerged plants has become a key issue that needs to be solved urgently. As for the current main direct casting method, it faces many difficulties.

[0003] In the traditional method of wrapping the roots of submerged plants with clay or mud for planting, the clay or mud is easy to loosen and break, making it difficult for submerged plants to be fixed in a suitable position for growth. The Chinese patent number CN104206161B provides a method for planting submerged plants and a pot-breaking model device that uses agar to wrap the roots of submerged plants for planting, solving the problem of looseness and breakage in the process of submerged planting wrapped with clay or mud. However, during the throwing process, due to the impact of the water surface, agar is also easy to break and it is difficult to maintain the upright state of submerged plants. The Chinese patent number CN104206161B provides a method for wrapping submerged plants with mud balls based on a submerged plant planting mud ball matrix, which wraps the stems of multiple submerged plants to form mud balls, and the roots of submerged plants are on the outside, which shortens the rooting time. However, during the operation, the height of the submerged plants needs to be screened, which increases the labor cost. In addition, in the actual seed throwing process, affected by water entry angle, water flow, waves and other hydrodynamic factors, once the submerged plants do not sink upright, it is easy to cause the stems of the submerged plants to break. Chinese patent number CN119054462A provides a method for restoring Vallisneria ovalis with seeds as propagation bodies under the background of heavy pollution. Vallisneria ovalis seeds are planted on the surface of a cylindrical agar gel and then thrown to increase the seed germination rate and seedling growth rate of submerged plants. However, during the throwing process, the cylindrical agar gel matrix may roll in the bottom mud and cannot achieve directional planting. It may also cause the seeds on the surface to be pressed into the bottom mud, limiting the germination of seeds and the growth of seedlings. Chinese patent number CN222108505U provides a visual underwater plant planting device that uses a seed throwing tube to achieve directional planting of submerged plants, but the seed throwing tube is in direct contact with the bottom mud, forming a relatively sealed state inside the tube, resulting in an increase in the pressure difference inside the seed throwing tube, slowing down the sedimentation rate of submerged plants during the seed throwing process, and reducing the seed throwing efficiency. In addition, it is difficult to meet the planting needs of a large area using a single seed tube.

[0004] Therefore, the present application designs a planting device for controlling the posture and orientation of submerged plants, which can effectively reduce the risk of the substrate being broken by water flow impact and precisely control the planting posture of submerged plants. Summary of the Invention

[0005] The purpose of the present invention is to provide a planting device for controlling the posture and orientation of submerged plants, aiming to solve the above existing problems.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A planting device for controlling the posture and orientation of submerged plants includes a seedling-raising plate, a floating plate, and a telescopic pipe that shields water flow debris for submerged plants and forms a falling channel; a plurality of groups of uniformly arranged planting holes are opened on the surface of the floating plate, there are a plurality of groups of telescopic pipes, the telescopic pipes are lapped with the floating plate through the planting holes, and the telescopic pipes extend downward through the planting holes; the submerged plants are placed on the seedling-raising plate, and the seedling-raising plate is placed on the upper surface of the floating plate;

[0007] The floating plate floats on the water surface, the telescopic pipe naturally sinks and unfolds under the influence of gravity, and stops after contacting the bottom mud; the submerged plants fall into the planting holes in the form of the disassembled seedling-raising plate, and the submerged plants fall into the bottom mud along the telescopic pipe.

[0008] By wrapping the gravity of the substrate, the submerged plants automatically sink to the bottom mud along the telescopic rod, and the telescopic rod can ensure that the plants sink vertically. During the sinking process of the submerged plants, the risk of the substrate being broken by water flow impact is effectively reduced. It provides a stable nutrient source and a firm attachment root for the submerged plants, and greatly improves the survival rate of the plants.

[0009] Furthermore, seedling-raising bins corresponding to the positions of the planting holes are opened on the surface of the seedling-raising plate. The seedling-raising bins are spindle-shaped structures, and the cross-sectional size gradually increases from top to bottom; there are a plurality of groups of seedling-raising plates, and the plurality of groups of seedling-raising plates are inserted into each other to form splicing seams for easy disassembly and assembly of the seedling-raising plates. A plurality of groups of through holes are opened on the outer wall of the telescopic pipe from top to bottom.

[0010] Through the design of the spindle-shaped seedling-raising bin, the falling form of the submerged plants conforms to the principle of hydrodynamics. When the submerged plants are wrapped and sink in the water, the water flow passes through the surface of the package. Due to the axisymmetric structure of the spindle shape, the acting forces on both sides of it by the water flow are equal in magnitude and opposite in direction, which makes the package always maintain axial stability during the sinking process and will not easily roll or shift. At the same time, under the action of the telescopic pipe, the center of gravity of the spindle-shaped package is always on the central axis, further ensuring the stability of its vertical sinking and precisely controlling the planting posture of the submerged plants.

[0011] Further, it also includes a thin rod, a recovery hole, a base, and an auxiliary mechanism for the recovery displacement of the thin rod; one end of the base is fixedly connected to the lower end of the telescopic tube, the other end of the base is rotatably connected to the lower end of the thin rod, the recovery hole is opened on the side of the planting hole, and the thin rod passes through the planting hole and extends above the floating board; the thin rod is a spiral metal rod with a quasi-rectangular cross-section but with arcs on both sides.

[0012] Through the provided auxiliary mechanism and the thin rod, after completing one planting task, the individual telescopic rod can be retracted or all the telescopic tubes can be lifted synchronously. When facing different waters and different planting areas, the device has higher adaptability, is more convenient for operators to operate, can be displaced to the next planting location without lifting the floating board, and the lockable design is more convenient for the daily storage and storage of the device, which can effectively reduce the labor intensity of the operators and improve the versatility and convenience of the device.

[0013] Further, through holes are opened on the seedling-raising board, and the through holes are used to accommodate the thin rod when the seedling-raising board is spliced with the floating board. The auxiliary mechanism includes a driving sleeve, a fixed sleeve, a vertical plate, a connecting rod, a synchronous driving rod, a spring telescopic rod, and a locking component; the fixed sleeve is fixedly arranged in the recovery hole, the thin rod is slidably connected with the fixed sleeve, the driving sleeve is designed with an inner and outer double layer, a limiting hole with the same cross-section as the thin rod is opened in the middle of the inner layer of the driving sleeve, the inner layer and the outer layer of the driving sleeve are connected by a one-way bearing, a locking component is arranged at the lower part of the driving sleeve, one end of the connecting rod is connected to the outer layer of the driving sleeve, the other end of the connecting rod is fixedly connected to the upper end of the spring telescopic rod, and the lower end of the vertical plate is fixedly connected to the rear end of the floating board.

[0014] Further, a plurality of groups of through grooves are opened on the surface of the vertical plate, the upper end of the spring telescopic rod is slidably connected with the through grooves, the lower end of the spring telescopic rod is fixedly connected to the vertical plate, the synchronous driving rod is located at the upper ends of all the spring telescopic rods, and the side part of the synchronous driving rod is slidably connected with the vertical plate through the spring telescopic rod; the thin rod passes through the inner layer of the driving sleeve. A limiting hole with the same cross-section as the thin rod is penetrated in the middle of the fixed sleeve, and the thin rod is slidably connected with the fixed sleeve through the limiting hole.

[0015] Further, the locking component includes an elastic buckle, a push rod, a driven rod, an arc-shaped locking block, a trapezoidal pin, and a spring; the push rod is slidably connected with the inner wall of the connecting rod, and an elastic buckle is arranged at the end of the push rod positioned on one side of the spring telescopic rod and extends to the outside of the connecting rod; the connecting rod is in an L-shaped structure, the driven rod is positioned in the short side of the connecting rod, the driven rod is slidably connected with the connecting rod, one end of the driven rod is fixedly connected to the trapezoidal pin, the other end of the driven rod passes through the connecting rod and is fixedly connected to the arc-shaped locking block, and the inner wall of the connecting rod is connected to the driven rod through a spring; the arc of the arc-shaped locking block is the same as the arc of the thin rod, and the arc-shaped locking block is made of a material with high friction and deformability.

[0016] Compared with the prior art, it has the following beneficial effects:

[0017] 1. Solve the problem of substrate fragmentation: In the existing submerged plant planting technology, the substrate is prone to fragmentation during the sinking process, resulting in the plants being unable to obtain sufficient nutrients and stable support. With the help of the gravity of the wrapped substrate, the submerged plants in the present invention automatically sink along the telescopic rod to the bottom mud, and the telescopic rod can ensure the vertical sinking of the plants. During the sinking process of the submerged plants, the risk of the substrate being fragmented due to water flow impact is effectively reduced. It provides a stable nutrient source and a firm attachment foundation for the submerged plants, greatly improving the survival rate of the plants.

[0018] 2. Control the plant posture: The present invention changes the conventional irregular shape of the package to a spindle shape. This unique spindle shape structure conforms to the principle of hydrodynamics. When the package sinks in water, the water flow passes over the surface of the package. Due to the axisymmetric structure of the spindle shape, the acting forces on both sides of it by the water flow are equal in magnitude and opposite in direction. This enables the package to always maintain axial stability during the sinking process and will not easily roll or shift. At the same time, under the action of gravity, the center of gravity of the spindle-shaped package is always on the central axis, further ensuring the stability of its vertical sinking and accurately controlling the planting posture of the submerged plants.

[0019] 3. Modular design improves flexibility: The seedling-raising plate can be flexibly spliced and disassembled, and can be adjusted according to different planting areas and requirements to adapt to diverse water environments. This modular design makes the planting operation more convenient. The planting scale and density can be flexibly arranged according to the actual situation. Compared with the traditional fixed-structure planting device, it has higher adaptability and operability. Description of the Drawings

Detailed implementation manners

[0031] In order to more easily understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention will be described in detail below in conjunction with the drawings as follows:

[0032] Embodiment 1

[0033] As Figure 1 shown, the present application proposes a planting device for controlling the posture and orientation of submerged plants, including a seedling raising plate 1, a floating plate 2, and a telescopic tube 3 that shields the submerged plants from water flow debris and forms a falling channel; a plurality of groups of evenly arranged planting holes 4 are formed on the surface of the floating plate 2, and a plurality of groups of telescopic tubes 3 are provided. The telescopic tube 3 is lapped with the floating plate 2 through the planting hole 4, and the telescopic tube 3 extends downward through the planting hole 4; the submerged plants are placed on the seedling raising plate 1, and the seedling raising plate 1 is placed on the upper surface of the floating plate 2;

[0034] The floating plate 2 floats on the water surface. The telescopic tube 3 naturally sinks and unfolds under the influence of gravity and stops after contacting the bottom mud; the submerged plants fall into the planting hole 4 in the form of disassembling the seedling raising plate 1, and the submerged plants fall into the bottom mud along the telescopic tube 3.

[0035] Referring to Figure 1 , a seedling raising bin 11 corresponding to the position of the planting hole 4 is formed on the surface of the seedling raising plate 1. The seedling raising bin 11 is of a spindle-shaped structure, and its cross-sectional size gradually decreases from top to bottom; a plurality of groups of seedling raising plates 1 are provided, and the plurality of groups of seedling raising plates 1 are inserted into each other to form a splicing seam 12 to facilitate the disassembly and assembly of the seedling raising plate 1.

[0036] Among them, the seedling-raising plate 1 has high flexibility. Through the insertion of mortise and tenon structures, convenient splicing and disassembly operations can be achieved. The seedling-raising chamber 11 is spindle-shaped and has a variable-diameter structure that is smaller at the top and larger at the bottom. Submerged plants complete the matrix wrapping process in the seedling-raising chamber 11 and at the same time complete the morphological fixation to ensure the stable morphology of the plants. The aperture and hole spacing of the seedling-raising plate 1 are precisely adapted to the planting holes 4 on the floating plate 2, and it can be directly placed and covered on the floating plate 2 to form a tight combined structure.

[0037] See Figure 1 , a plurality of through holes 31 are provided on the outer wall of the telescopic tube 3 from top to bottom. The telescopic tube 3 adopts a multi-stage nested structure, with a hollow cavity inside and specific through holes 31 on the outer wall. When placed on the water surface, it can automatically complete the bottom-finding action by its own gravity to ensure vertical positioning. The telescopic rod passes through the planting hole 4 of the floating bed. The upper outer edge of the first-stage telescopic rod is in a flared shape, and its diameter is slightly larger than the planting hole 4, and it can reliably buckle on the planting hole 4 to form a stable support and positioning.

[0038] Working principle: During the planting operation, the seedling-raising plate 1 is placed on the floating plate 2, and the seedling-raising plate 1 is disassembled. The submerged plants wrapped with the matrix automatically fall into the planting hole 4. With the gravity of the wrapped matrix, the submerged plants automatically sink along the telescopic rod to the bottom mud to complete precise planting. After the sowing is completed, the floating plate 2 can be vertically lifted and moved to the next water area, which is convenient for quickly transferring to other water areas and continuing the sowing operation.

[0039] Embodiment 2

[0040] As another embodiment, as Figures 2 to 8 shown, this embodiment further includes a thin rod 5, a recovery hole 6, a base 7, and an auxiliary mechanism 8 for the recovery displacement of the thin rod 5 compared with Embodiment 1; one end of the base 7 is fixedly connected to the lower end of the telescopic tube 3, and the other end of the base 7 is rotatably connected to the lower end of the thin rod 5. The recovery hole 6 is opened on the side of the planting hole 4, and the thin rod 5 passes through the planting hole 4 and extends above the floating plate 2; the thin rod 5 is a spiral metal rod with a cross-section that is approximately rectangular but with arcs on both sides.

[0041] When the telescopic tube 3 is driven to descend under the influence of its own gravity, the thin rod 5 is synchronously driven to move downward. Due to the limitation of the recovery hole 6 and the auxiliary mechanism 8, the thin rod 5 always maintains a vertical state. Among them, the thin rod 5 is made of metal, and its surface is sprayed with an anti-corrosion coating to prevent the water body from corroding the thin rod 5.

[0042] See Figure 2, a through track 13 is provided on the seedling-raising plate 1, and the track 13 is used to accommodate the thin rod 5 when the seedling-raising plate 1 is spliced with the floating plate 2. In this embodiment, the seedling-raising plate 1 is placed on the upper part of the floating plate 2 in an inserted manner through the front end of the floating plate 2, so that the thin rod 5 is accommodated in the track 13, preventing the movement of the thin rod 5 from affecting the disassembly of the seedling-raising plate 1.

[0043] See Figures 3 to 8 As shown, the auxiliary mechanism 8 includes a driving sleeve 81, a fixing sleeve 82, a vertical plate 83, a connecting rod 84, a synchronous driving rod 85, a spring telescopic rod 86 and a locking component 87; the fixing sleeve 82 is fixedly arranged in the recovery hole 6, the thin rod 5 is slidably connected with the fixing sleeve 82, the driving sleeve 81 is designed with an inner and outer double layer, a limiting hole 89 with the same cross-section as the thin rod 5 is opened in the middle of the inner layer of the driving sleeve 81, the inner layer of the driving sleeve 81 and the outer layer of the driving sleeve 81 are connected through a one-way bearing 88, a locking component 87 is arranged at the lower part of the driving sleeve 81, one end of the connecting rod 84 is connected with the outer layer of the driving sleeve 81, the other end of the connecting rod 84 is fixedly connected with the upper end of the spring telescopic rod 86, and the lower end of the vertical plate 83 is fixedly connected with the rear end of the floating plate 2.

[0044] Among them, when the telescopic pipe 3 moves downward under gravity, it drives the thin rod 5 to move downward synchronously. The friction between the fixing sleeve 82 and the thin rod 5 is relatively low and will not affect the natural fall of the thin rod 5, but will drive the thin rod 5 to rotate; the one-way bearing 88 between the inner layer and the outer layer of the driving sleeve 81 enables the inner layer of the driving sleeve 81 to rotate only in one direction and is limited in the other direction.

[0045] By placing the floating plate 2 on the water surface, then the telescopic pipe 3 naturally falls to the bottom, and at the same time drives the thin rod 5 to rotate and move downward. During this process, the inner layer of the driving sleeve 81 rotates naturally driven by the thin rod 5. After inserting the seedling-raising plate 1 to the upper end of the floating plate 2, the seedling-raising plate 1 is disassembled, and the wrapped submerged plants naturally fall into the planting holes 4 and naturally fall to the bottom mud along the direction of the telescopic pipe 3. After planting, by pulling the connecting rod 84 downward to drive the driving sleeve 81 to move downward, since the one-way bearing 88 limits the inner layer of the driving sleeve 81 from rotating in the reverse direction, the inner layer of the driving sleeve 81 drives the thin rod 5 to rotate in the reverse direction during the downward movement. The thin rod 5 rotating in the reverse direction shows a tendency to move upward under the limit of the fixing sleeve 82, pulling the telescopic pipe 3 to recover, and locking the thin rod 5 through the locking component 87.

[0046] See Figure 4 And Figure 5 , a plurality of through chutes 831 are provided on the surface of the vertical plate 83, the upper end of the spring telescopic rod 86 is slidably connected with the chute 831, the lower end of the spring telescopic rod 86 is fixedly connected with the vertical plate 83, the synchronous driving rod 85 is located at the upper ends of all the spring telescopic rods 86, and the side part of the synchronous driving rod 85 is slidably connected with the vertical plate 83 through the spring telescopic rod 86; the thin rod 5 passes through the inner layer of the driving sleeve 81.

[0047] When using certain planting holes 4 during single - time planting, the corresponding connecting rod 84 can be unlocked individually, allowing the telescopic tube 3 to fall naturally. After planting, pulling the connecting rod 84 downward compresses the spring telescopic rod 86. The connecting rod 84 drives the driving sleeve 81 to move downward, driving the thin rod 5 to rotate and rise. After releasing the hand, the spring telescopic rod 86 rebounds and pushes the connecting rod 84 back to the initial position. During this process, the inner layer of the driving sleeve 81 rotates without being limited, and does not drive the thin rod 5 to rotate. Repeatedly pulling the connecting rod 84 can drive the corresponding thin rod 5 to retract, and then pull the corresponding telescopic tube 3 to retract and lock; when all thin rods 5 need to be driven simultaneously, unlock all the locking components 87, and pull the synchronous driving rod 85. The synchronous driving rod 85 can simultaneously drive all the connecting rods 84 to move downward, and then synchronously drive all the thin rods 5 to move.

[0048] See Figure 6 The middle of the fixing sleeve 82 is provided with a limiting hole 89 having the same cross - section as the thin rod 5. The thin rod 5 is slidably connected to the fixing sleeve 82 through the limiting hole 89.

[0049] Embodiment 3

[0050] As another embodiment, as Figure 8 and Figure 9 shown, the locking component 87 includes an elastic buckle 871, a push rod 872, a driven rod 873, an arc - shaped locking block 874, a trapezoidal pin 875, and a spring 876; the push rod 872 is slidably connected to the inner wall of the connecting rod 84. An elastic buckle 871 is provided at the end of the push rod 872 positioned on one side of the spring telescopic rod 86 and extends outside the connecting rod 84; the connecting rod 84 has an L - shaped structure. The driven rod 873 is positioned inside the short side of the connecting rod 84. The driven rod 873 is slidably connected to the connecting rod 84. One end of the driven rod 873 is fixedly connected to the trapezoidal pin 875, and the other end of the driven rod 873 passes through the connecting rod 84 and is fixedly connected to the arc - shaped locking block 874. The inner wall of the connecting rod 84 is connected to the driven rod 873 through the spring 876.

[0051] When the position of the telescopic tube 3 needs to be locked, press the push rod 872 exposed outside the connecting rod 84, causing the push rod 872 to generate a horizontal displacement. The end of the push rod 872 contacts the trapezoidal pin 875. Using the inclined surface of the trapezoidal pin 875, the trapezoidal pin 875 pushes the driven rod 873 to generate a displacement, and then pushes the arc - shaped locking block 874 into the spiral groove of the thin rod 5, thus completing the locking of the thin rod 5. At the same time, the connecting rod 84 is also locked and cannot move in the vertical direction. The position of the push rod 872 is locked by the provided elastic buckle 871. Pressing the push rod 872 again can unlock it. The push rod 872 returns to the initial position, and the trapezoidal pin 875 returns to the initial position under the action of the spring 876, pulling the arc - shaped locking block 874 to retract.

[0052] It should be noted that the arc of the arc-shaped locking block 874 is the same as that of the thin rod 5, and the arc-shaped locking block 874 is made of a deformable material with high friction. After the arc-shaped locking block 874 is pushed into the spiral groove of the thin rod 5, the arc-shaped locking block 874 is compressed and deformed, increasing the contact area with the thin rod 5 to obtain greater friction, thereby realizing the locking of the thin rod 5; the material of the arc-shaped locking block 874 is preferably rubber material.

[0053] Working principle:

[0054] After inserting the seedling-raising plate 1 onto the upper end of the floating plate 2, the seedling-raising plate 1 is split, and the wrapped submerged plants naturally fall into the planting holes 4 and then fall into the bottom mud along the direction of the telescopic tube 3. After the planting is completed, by pulling the connecting rod 84 downward, the driving sleeve 81 moves downward. The downward movement of the inner layer of the driving sleeve 81 drives the thin rod 5 to rotate in the reverse direction. The thin rod 5 rotating in the reverse direction has a tendency to move upward under the limit of the fixed sleeve 82, pulling the telescopic tube 3 to retract. When it is necessary to lock the position of the telescopic tube 3, press the push rod 872 exposed from the connecting rod 84, so that the push rod 872 generates a horizontal displacement. The end of the push rod 872 contacts the trapezoidal pin 875. Using the inclined surface of the trapezoidal pin 875, the trapezoidal pin 875 is used to push the driven rod 873 to generate a displacement, and then the arc-shaped locking block 874 is pushed into the spiral groove of the thin rod 5, and the locking of the thin rod 5 can be completed. Press the push rod 872 again to unlock. The push rod 872 returns to the initial position, and the trapezoidal pin 875 returns to the initial position under the action of the spring 876, pulling the arc-shaped locking block 874 to retract; when it is necessary to retract all the telescopic tubes 3, unlock all the locking components 87, and pull the synchronous driving rod 85. The synchronous driving rod 85 can simultaneously drive all the connecting rods 84 to move downward, and then synchronously drive all the thin rods 5 to move.

[0055] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention all fall within the protection scope of this technical solution.
