Description

Technical Field

[0001] This application relates to the field of river ecological restoration technology, and in particular to a river ecological restoration device and restoration method. Background Technology

[0002] Ecological floating islands are an artificial aquatic ecological restoration technology. They utilize buoyancy materials to construct floating platforms on the water surface, where suitable aquatic or terrestrial plants are planted. The plant roots naturally extend into the water, forming a vast network structure that effectively absorbs excess nutrients such as nitrogen and phosphorus, inhibiting algae growth. Simultaneously, the roots provide an attachment medium for microorganisms, forming biofilms and enhancing the degradation of organic pollutants. Furthermore, floating islands create habitats for fish, insects, and other organisms, increasing biodiversity. They offer advantages such as low cost, good aesthetic appeal, no need for land occupation, and ease of management, and are widely used for water purification and ecological landscape creation in lakes, rivers, and ponds. However, existing river ecological floating islands face the challenge of being easily washed away during flood season when river flow and velocity increase. Summary of the Invention

[0003] To address the problem of existing floating ecological islands in riverbeds being easily washed away during flood season due to increased water flow and velocity, this application provides a riverbed ecological restoration device, comprising a vegetation bin, a fixed base, and a connecting belt. One end of the connecting belt is fixed to the fixed base, and the other end of the connecting belt is connected to one side of the vegetation bin.

[0004] Furthermore, a long strip-shaped intermediate component is installed at the bottom of the vegetation compartment, the vegetation compartment is rotatably connected to the intermediate component, and the connecting strap is connected to one end of the intermediate component.

[0005] Furthermore, the middleware is provided with a drive component for driving the vegetation bin to rotate; The drive assembly includes a transition piece rotatably connected to one end of the intermediate piece away from the connecting strip along the axis of the intermediate piece, and a drive blade coaxially fixed to the transition piece, wherein a gear set is provided between the transition piece and the vegetation bin. The water flow impacts the drive blades, causing them to rotate. The drive blades, through the transition piece and the gear set, drive the vegetation bin to rotate.

[0006] Furthermore, the intermediate component has an arrangement cavity arranged along its own axis, the top of the arrangement cavity has a connecting hole, and a connecting rod is vertically fixed at the center of the bottom of the vegetation bin, the connecting rod passing through the connecting hole and extending into the arrangement cavity; The gear set includes a first bevel gear located in the arrangement cavity and coaxially fixed to the connecting rod, and a second bevel gear rotatably connected to the arrangement cavity and used in conjunction with the first bevel gear; One end of the transition piece is located inside the arrangement cavity and coaxially connected to the second bevel gear, while the other end extends out of the arrangement cavity and is connected to the drive blade.

[0007] Furthermore, a polygonal drive hole is coaxially provided on the second bevel gear; The drive assembly includes a transition section and a drive section. The transition section is located within the arrangement cavity and has a tubular shape adapted to the drive hole. The transition section slides through the drive hole. The driving part is a rod-shaped structure adapted to the transition part. The transition part is slidably sleeved onto the driving part. An elastic element is provided between the transition part and the intermediate part. Under the action of the elastic element, the transition part tends to be sleeved outside the connecting part. The drive unit extends out of the arrangement cavity, the drive unit is rotatably connected to the intermediate component, and the drive blade is installed on the drive unit; A mounting hole is provided at one end of the intermediate component where the connecting strip is located, and the connecting strip passes through the mounting hole and connects to the end of the transition portion away from the driving portion. The upper wall of the arrangement cavity is provided with an installation hole, and a limiting component is slidably installed in the installation hole. The limiting component includes a base part and a limiting part. The base part is a vertically arranged tubular structure. A track is vertically arranged in the arrangement cavity. The base part is slidably connected to the track. The limiting part is slidably connected to the base part. An elastic component is fixed between the limiting part and the base part. Under the action of the elastic component, the top of the limiting part tends to protrude from the top of the base part. The outer periphery of the transition section is coaxially provided with a tapered guide section that cooperates with the base section, and a plane one, a guide slope and a plane two are formed on the transition section; When the bottom of the base is erected to the first plane, the top of the limiting part detaches from the lower surface of the vegetation bin; when the bottom of the base is erected to the second plane, the top of the limiting part abuts against the lower surface of the vegetation bin.

[0008] Furthermore, a rotating component is rotatably connected to one end of the transition portion facing the mounting hole. A limiting rod is integrally provided on the rotating component, and a limiting groove is provided in the corresponding arrangement cavity along the axial direction of the intermediate component. The limiting rod is slidably connected to the limiting groove.

[0009] Furthermore, a water-blocking component is provided on one side of the vegetation bin.

[0010] Furthermore, a positioning groove is provided on the lower surface of the vegetation bin, and a positioning member is fixed on the outside of the limiting member. When the bottom of the limiting member is located on the second plane, the top of the positioning member extends into the positioning groove, and at this time the water-blocking member is located on the water-facing side of the vegetation bin.

[0011] Furthermore, the water-blocking component is a telescopic structure, and the water-blocking component includes several telescopic parts that are attached to each other, wherein one side of the telescopic part is fixed to the vegetation compartment; Two adjacent telescopic sections form a group. In the same group, the telescopic section closer to the vegetation bin is vertically provided with a slide rail, and the other telescopic section is fixed with a sliding block. The sliding block is slidably connected to the slide rail, and an elastic member is fixed between the slider and the telescopic section where the slide rail is located. Under the action of the elastic member, the telescopic section where the slider is located has a tendency to extend upward. A locking mechanism is provided between the water-blocking component and the intermediate component.

[0012] Furthermore, the locking mechanism includes an adjusting member and several fixing members, each of which corresponds to one of the telescopic parts. Each fixing member includes a fixing rod that is vertically fixed to the lower surface of the telescopic part. The bottom end of the fixing rod has an installation notch along the axial direction of the intermediate member. A fixing block is slidably connected in the installation notch, and a driving spring is fixed between the fixing block and the fixing rod. The intermediate component has an installation cavity arranged along its own axial direction. The upper wall of the installation cavity has several fixing holes, and each fixing hole corresponds to a fixing rod. The fixing rod extends downward through the fixing hole into the installation cavity, and the fixing block extends out of the installation notch under the action of the drive spring and hooks onto the upper wall of the installation cavity. The adjusting member is slidably installed into the mounting cavity along the axial direction of the intermediate member, a push rod is fixed on the adjusting member, and a tension spring is provided between the adjusting member and the intermediate member; Several of the fixing members are located between the push rod and the transition portion, and the pushing portion tends to move toward the fixing block under the action of the tension spring; The intermediate component has a connecting cavity arranged along its own axial direction. One end of the connecting cavity is connected to the arrangement cavity, and the other end of the connecting cavity is connected to the mounting cavity. An adjustment rope is provided inside the connecting cavity. One end of the adjustment rope extends into the mounting cavity and is fixed to the side of the adjustment member away from the arrangement cavity. The other end extends into the arrangement cavity and is connected to the end of the transition part away from the drive blade.

[0013] In summary, the present invention has at least the following beneficial effects: 1. By setting the connecting strap to the vegetation bin as a side connection, the vegetation bin is effectively prevented from overturning around the fixed base, which greatly improves the overall stability of the device under strong water flow. 2. Through a linkage speed-limiting mechanism consisting of a drive assembly and a guide section and limiting components (including a base section, a limiting section, and elastic components), under normal conditions, the water flow drives the blades to rotate the vegetation chamber, ensuring uniform light exposure for the vegetation. During flood peaks, the accelerated water flow pushes the transition section axially, causing the limiting component to press against the vegetation chamber and slow it down. This structure enables intelligent adjustment of the vegetation chamber's rotation speed according to the water flow, significantly enhancing its resistance to flood peak impacts while ensuring daily ecological functions. 3. By incorporating a water-blocking component, positioning component, and locking mechanism (including fixing component, adjusting component, and adjusting rope) linked to the transition component, this design can automatically control the water-blocking height based on changes in the thrust of the water flow on the vegetation compartment and intermediate component. When the water flow thrust increases, the connecting belt pulls the transition component towards the adjusting component. The adjusting component and the push rod move towards the fixing component under the action of the tension spring. The push rod sequentially releases the locking of each level of the telescopic component, and each telescopic component extends step by step under the action of the push spring. This structure achieves adaptive and graded adjustment of the water-blocking height, providing appropriate wave protection for flood peaks of varying intensities, preventing damage to vegetation and the device from being knocked over.

[0016] This application provides a river ecological restoration device, referring to... Figure 1 and Figure 2 It includes a circular vegetation chamber 1, several planting areas 11 for planting aquatic ecological restoration vegetation are set on the vegetation chamber 1, and a fixed base 2 for fixing the position of the vegetation chamber 1. The fixed base 2 is placed at the bottom of the river. A connecting strip 3 is set between the vegetation chamber 1 and the fixed base 2. One end of the connecting strip 3 is fixedly connected to the fixed base 2, and the other end of the connecting strip 3 is connected to one side of the vegetation chamber 1.

[0017] Compared to the traditional method of directly fixing the connecting strap 3 to the center of the bottom of the vegetation bin 1, in this case, because the connecting strap 3 is connected to one side of the vegetation bin 1, the vegetation bin 1 is less likely to overturn when encountering a flood peak as the water flow gradually increases.

[0018] Furthermore, a long strip-shaped intermediate component 4 is installed at the bottom of the vegetation bin 1 along the radial direction of the vegetation bin 1.

[0019] Reference Figure 3 and Figure 4 The vegetation bin 1 is rotatably connected to the intermediate component 4, and the end of the connecting belt 3 away from the fixed base 2 is connected to one end of the intermediate component 4.

[0020] Because the vegetation chamber 1 is rotatably connected to the intermediate component 4, the state of the vegetation chamber 1 will rotate to a certain extent with the change of water flow under the push of the water flow, so that the plants in the vegetation chamber 1 receive more uniform light, which is conducive to the growth of the plants in the vegetation chamber 1, thereby improving the restoration effect of the restoration device on the river water quality.

[0021] Furthermore, the intermediate component 4 is equipped with a drive assembly 5 for driving the vegetation bin 1 to rotate. The drive assembly 5 is located at the end of the intermediate component 4 away from the connecting belt 3. Specifically, the drive assembly 5 includes a transition component 51 arranged along the axis of the intermediate component 4. The transition component 51 is rotatably connected to the intermediate component 4. There are four drive blades 52, which are evenly distributed circumferentially along the axis of the drive unit 512. Each blade has an angle of attack of 15° to 45° with the direction of the water flow and is slightly twisted clockwise along the axis. The root of the blade is wider than the tip of the blade and is fixedly connected to the drive unit 512 to ensure that a continuous tangential torque is generated when the water flow impacts, driving the drive unit 512 to rotate. A gear set 53 is provided between the transition component 51 and the vegetation bin 1.

[0022] As the water flow in the river propels the drive blade 52 to rotate, the drive blade 52, through the cooperation of the transition piece 51 and the gear set 53, drives the vegetation chamber 1 to rotate together, thereby enabling the vegetation chamber 1 to rotate continuously and stably, ensuring that the vegetation in the vegetation chamber 1 can receive more uniform sunlight.

[0023] An arrangement cavity 41 is provided in the middle part 4 along its own axis; a connection hole 411 is provided at the top of the arrangement cavity 41; a connecting rod 12 is vertically fixed at the center of the bottom of the vegetation bin 1; the bottom of the connecting rod 12 passes through the connection hole 411 and extends into the arrangement cavity 41. The gear set 53 includes a first bevel gear 531 coaxially fixed to the bottom end of the connecting rod 12, and a second bevel gear 532 rotatably connected to the inner wall of the arrangement cavity 41. The second bevel gear 532 meshes with the first bevel gear 531, and the second bevel gear 532 has a polygonal drive hole 5321 that cooperates with the transition piece 51. The transition component 51 includes a transition section 511 and a drive section 512. The transition section 511 is configured as a tubular structure adapted to the drive section 512. The transition section 511 is located in the arrangement cavity 41 and is adapted to the drive hole 5321. The transition section 511 slides through the drive hole 5321. One end of the drive section 512 slides into the transition section 511, and the other end of the drive section 512 extends through the intermediate member 4. The drive section 512 and the intermediate member 4 are rotatably connected. The drive blade 52 is fixedly installed to the end of the drive section 512 that extends out of the intermediate member 4. The transition section 511 and the drive section 512 are slidably connected (rather than fixedly connected). The core feature is the separation of rotational motion and axial movement: the drive section 512 is only responsible for transmitting rotational force to the transition section 511. The transition section 511 can move independently along the axial direction of the drive section 512, avoiding the transmission of axial force to the drive section 512 and the drive blade 52, ensuring the stable rotation of the drive assembly 5, and at the same time ensuring the reliability of the linkage between the limit member 6 and the locking mechanism 8 during the flood peak.

[0024] Reference Figure 5 The middle part 4 has a mounting hole 412 at one end that is connected to the connecting strip 3; Reference Figure 6 A rotating component 5111 is rotatably connected to one end of the transition section 511 facing the mounting hole 412. A limiting rod 5111a is integrally provided on the side wall of the rotating component 5111. A limiting groove 413 is formed on the inner wall of the corresponding arrangement cavity 41 along the axial direction of the intermediate component 4. The limiting rod 5111a extends into the limiting groove 413. With the cooperation of the limiting rod 5111a and the limiting groove 413, the rotating component 5111 can only move along the axial direction of the intermediate component 4, and relative rotation can also occur between the rotating component 5111 and the transition section 511. The connecting band 3 passes through the mounting hole 412 and is fixedly connected to the rotating component 5111 on the transition section 511. The rotating component 5111 is designed to minimize the rotation of the connecting band 3 during the rotation of the transition section 51.

[0025] Reference Figure 3 An elastic element 5116 is fixedly installed between the transition part 511 and the intermediate part 4. The elastic element 5116 is generally a spring. The restoring force of the elastic element 5116 causes the transition part 511 and the driving part 512 to move closer to each other.

[0026] Reference Figure 7A limiting hole 414 is provided at the top of the arrangement cavity 41, and a limiting member 6 is slidably connected in the limiting hole 414. Specifically, the limiting member 6 includes a base part 61 and a limiting part 62. The base part 61 is a vertically arranged tubular structure, and a track 415 is vertically fixed on the inner wall of the arrangement cavity 41. A slider 611 is integrally provided on the side wall of the base part 61, and the slider 611 is slidably connected to the track 415. The limiting part 62 is a vertically arranged rod-shaped structure, and the limiting part 62 is slidably connected to the base part 61 in the vertical direction. An elastic member 63 is fixed between the limiting part 62 and the base part 61. Under the action of the elastic member 63, the top end of the limiting part 62 tends to extend beyond the top of the base part 61.

[0027] A tapered guide portion 5112 is coaxially fixed to the periphery of the transition portion 511. For ease of subsequent description, the guide portion 5112 is provided on the transition portion 511 to form a first plane 5113, a guide slope 5114, and a second plane 5115.

[0028] In normal working condition, the bottom of the base 61 of the limiting member 6 abuts against the plane 5113, and the top of the limiting part 62 of the limiting member 6 disengages from the lower surface of the vegetation bin 1. The water flow in the river pushes the drive blade 52 to drive the drive part 512 to rotate. When the drive part 512 rotates, it engages with the sliding spline of the bevel gear 532 through the transition part 511, causing the bevel gear 532 to rotate synchronously, thereby meshing with the bevel gear 531 to drive the vegetation bin 1 to rotate, and thus driving the vegetation bin 1 to rotate.

[0029] When a flood peak occurs, as the water flow gradually increases, the water flow drives the rotation of the drive blade 52 to accelerate, thus increasing the rotational speed of the vegetation bin 1. Furthermore, the thrust of the river water flow on the vegetation bin 1 and the intermediate component 4 gradually increases. During this process, the bottom of the limiting component 6 moves upward along the guide slope 5114, and the top of the limiting part 62 gradually presses against the vegetation bin 1 to reduce its rotational speed, thereby ensuring the stability of the vegetation bin 1. During the flood peak, the transition part 511 can move axially along the drive hole 5321 of the bevel gear 2 532 without affecting rotational transmission, while simultaneously triggering the limiting component 6 to decelerate. To ensure smoother relative movement of the bottom of the limiting component 6 between the transition parts 511, a ball bearing 612 is rotatably connected to the bottom of the base part 61.

[0030] Water-blocking components 7 are installed on the sides of the vegetation bin 1. When a flood peak occurs, the water-blocking components 7 can block the waves. On the one hand, the water-blocking components 7 can also protect the vegetation inside the vegetation bin 1, and on the other hand, can prevent the vegetation bin 1 from being knocked down by the waves as much as possible.

[0031] A positioning groove 13 is provided on the lower surface of the vegetation bin 1, and an additional hole 416 is provided on the top of the corresponding arrangement cavity 41. An "L"-shaped positioning member 64 is fixed on the side wall of the limiting member 6. The bottom of the positioning member 64 can be fixed to the base part 61 or the limiting part 62 of the limiting member 6. In this case, the positioning member 64 is fixed to the base part 61, and the positioning member 64 is aligned with the additional hole 416.

[0032] As the bottom of the base 61 slides upward along the guide slope 5114, there is a critical point near the plane 5115. When the bottom of the base 61 reaches the critical point, the top of the positioning member 64 presses against the bottom of the vegetation bin 1. At this time, the top of the positioning member 64 rubs against the vegetation bin 1, which can help the limiting member 6 to restrict the rotation of the vegetation bin 1. During this process, as the vegetation bin 1 continues to rotate, when the positioning groove 13 is aligned with the top of the positioning member 64, the limiting member 6 can continue to slide upward along the guide slope 5114 to the plane 5115. When the bottom of the limiting member 6 slides to the plane 5115, the top of the positioning member 64 inserts into the positioning groove 13. At this time, the vegetation bin 1 cannot rotate. In this position, the water-blocking member 7 is located on the water-facing side of the vegetation bin 1, that is, the side where the connecting strip 3 and the intermediate member 4 are connected. At this time, the water-blocking member 7 can better protect the vegetation bin 1.

[0033] Reference Figure 2 The vegetation compartment 1 has an assembly notch 14 for installing the water-blocking component 7.

[0034] Reference Figure 5 and Figure 8 In this case, the water-blocking component 7 is configured as a telescopic structure. Specifically, the water-blocking component 7 includes several arc-shaped telescopic parts 71 that are attached one after another. The number of telescopic parts 71 can be determined according to the actual situation. In this case, three telescopic parts 71 are used as an example. The innermost telescopic part 71 (the side closest to the center of the vegetation chamber 1) is fixed to the bottom of the assembly notch 14 of the vegetation chamber 1 as the fixed reference for the water-blocking component 7. The other telescopic parts 71 are movable telescopic parts that can slide out relative to the fixed reference. Two connected telescopic parts 71 form a group. In the same group of two telescopic parts 71, the telescopic part 71 closer to the vegetation chamber 1 is vertically provided with a slide rail 711. The corresponding telescopic part 71 is integrally provided with a sliding block 712. The sliding block 712 is slidably connected to the slide rail 711. A push spring 713 is fixed between the sliding block 712 and the inner wall of the slide rail 711. Under the action of the push spring 713, the telescopic part 71 where the sliding block 712 is located tends to extend upward out of the assembly notch 14. Fixed to the innermost telescopic part 71 of the vegetation bin 1 (attached) Figure 5The right side is always located within the assembly notch 14, with its top flush with the upper surface of the vegetation compartment 1, and does not participate in the extension; the movable telescopic part on the left side extends step by step relative to the fixed reference through the slide rail 711 and the sliding block 712 to achieve water blocking height adjustment.

[0035] A locking mechanism 8 is provided between the water-blocking component 7 and the intermediate component 4. It should be explained that in this case, the locking mechanism 8 is only provided for the movable telescopic part. The function of the locking mechanism 8 is to release the corresponding number of telescopic parts 71 extending out of the assembly notch 14 according to the size of the water flow in the river.

[0036] Specifically, the locking mechanism 8 includes several fixing members 81, each corresponding to a certain number of telescopic parts 71. The fixed telescopic part (right side) does not require fixing members 81; only the movable telescopic part (attached) on the left side... Figure 5 Fixing member 81 is provided on the lower surface of the two telescopic parts (left and middle). The fixing member 81 includes a fixing rod 811 that is vertically fixed to the lower surface of the telescopic part 71. The bottom of the fixing rod 811 is provided with an installation notch 8111 along the axial direction of the intermediate part 4. A fixing block 812 is slidably connected in the installation notch 8111. A driving spring 813 is fixed between the fixing block 812 and the fixing rod 811. The driving spring 813 is arranged along the axial direction of the intermediate part 4.

[0037] An installation cavity 417 is provided in the middle part 4 along the axial direction of the middle part 4. The top of the installation cavity 417 is provided with a number of fixing holes 418 that are adapted to the fixing rod 811. The fixing member 81 slides through the fixing holes 418 and extends into the installation cavity 417. The fixing block 812 extends out of the installation notch 8111 to the side away from the transition member 51 under the action of the driving spring 813 and hooks onto the upper wall of the installation cavity 417, thereby fixing the telescopic part 71.

[0038] The locking mechanism 8 also includes an adjusting member 82 that is slidably disposed in the mounting cavity 417 along the axial direction of the intermediate member 4. A push rod 821 is fixed on the adjusting member 82, and the top of the push rod 821 is aligned with the fixing block 812.

[0039] A tension spring 822 is provided between the adjusting member 82 and the intermediate member 4. Under the action of the tension spring 822, the adjusting member 82 tends to move towards the transition member 51.

[0040] A connecting cavity 419 is provided on one side of the mounting cavity 417 along the axis of the intermediate member 4. One end of the connecting cavity 419 is connected to the arrangement cavity 41, and the other end of the connecting cavity 419 is connected to the mounting cavity 417. An adjusting rope 83 is fixed to the end of the adjusting member 82 away from the transition member 51. After passing through the connecting cavity 419, the adjusting rope 83 is connected to the transition part 511 of the transition member 51. The transition part 511 pulls the adjusting member 82 through the adjusting rope 83, so that the push rod 821 on the adjusting member 82 is located on the side of the several fixing holes 418 away from the transition member 51.

[0041] As the water flow velocity in the river increases, the thrust exerted by the water flow on the intermediate component 4 and the vegetation chamber 1 gradually increases. Under the action of the connecting belt 3, the transition part 511 approaches the adjusting component 82. At this time, the tension spring 822 pulls the adjusting component 82 towards the transition part 511. When the push rod 821 on the adjusting component 82 contacts the fixing block 812, it pushes the fixing block 812 to slide into the installation notch 8111. When the fixing block 812 disengages from the hook on the upper wall of the installation cavity 417 and enters the fixing position, the fixing of the telescopic part 71 is released. Under the action of the push spring 713, the telescopic part 71 extends upward to produce a water-blocking effect. In this way, as the water flow continues to increase, several telescopic parts 71 extend in sequence, which can adapt to more types of flood peaks and thus ensure the stability of the vegetation chamber 1.

[0042] A reset slope 8121 is provided on the side of the bottom of the fixing block 812 away from the drive part 512. By setting the reset slope 812, after the flood peak recedes, the staff presses down on the telescopic part 71. During the downward movement of the telescopic part 71, the reset slope 8121 will gradually guide the fixing block 812 to align with the fixing hole 418 after contacting the intermediate part 4, so that the fixing block 812 can pass smoothly through the fixing hole 418 and hook onto the upper wall of the installation cavity 417, thereby making it easier for the staff to reset the telescopic part 71.

[0043] The implementation principle of this scheme is as follows: During normal water flow, the drive blade 52 is driven to rotate through the transition piece 51 and gear set 53, so that the vegetation chamber 1 is evenly exposed to light, which is conducive to the growth of vegetation. During flood peaks, the water flow accelerates and drives the drive blade 52, the vegetation chamber 1 rotates faster and the thrust increases. The bottom of the limiting piece 6 rises along the guide slope 5114, and the limiting part 62 presses against the vegetation chamber 1 to reduce the rotation speed. When approaching the critical point, the top of the positioning piece 64 presses against the vegetation chamber 1 to assist in limiting it. After the positioning groove 13 is aligned with the top of the positioning piece 64, the positioning piece 64 is inserted into the positioning groove 13, and the vegetation chamber 1 stops rotating. At this time, the water-blocking piece 7 is located on the water-facing side to better protect the vegetation. At the same time, the water flow speed increases and the thrust increases. Under the action of the connecting belt 3, the transition part 511 approaches the adjusting part 82, the tension spring 822 pulls the adjusting part 82, and the push rod 821 pushes the fixing block 812 to release the fixation of the telescopic part 71.

[0044] A method for river ecological restoration using a river ecological restoration device includes the following steps: S1: Equipment Deployment and Routine Operation Steps: Select installation location → Plant plants → Start running Specific steps: Installation site selection: In the section of the river that needs to be purified (such as slow-flowing areas or heavily polluted areas), fix the fixed base of the device to the riverbed and connect the floating vegetation bins with connecting straps.

[0045] Planting: Plant the selected aquatic purification plants in the planting area of ​​the vegetation chamber.

[0046] Start-up: Once the device is placed in water, the water flow naturally propels the drive blades, causing the plant chamber to rotate slowly. The plants receive even sunlight and begin efficiently purifying the water. Regular checks of plant growth and water quality are all that's needed.

[0047] S2: Flood Season Response and Maintenance Steps: Pre-flood inspection → Post-flood reset Specific steps: Pre-flood season inspection: Before the flood season, check whether the connecting belts, fixed bases and moving parts are secure and intact to ensure that the device can work normally.

[0048] Post-flood reset: After the flood, inspect the device. Once the water flow has returned to a steady level, manually push the floodgate back and unlock the vegetation compartment to restart its rotation. Inspect and clear debris, and replant any damaged vegetation.
