Technical Field

[0001] This invention relates to the field of ecological restoration technology, and in particular to a device for promoting the growth of plants in tidal wetlands and salt marshes. Background Technology

[0002] Tidal wetland salt marsh ecosystems play a vital role in maintaining biodiversity, purifying water quality, and mitigating storm surges. However, due to human activities and climate change, the area of ​​tidal wetlands is shrinking, posing numerous challenges to the growth of salt marsh plants. Current methods of cultivating salt marsh plants largely rely on natural environmental conditions and lack effective human intervention, making it difficult to ensure the healthy growth of plants in complex tidal environments.

[0003] Currently, although there are some auxiliary devices for the growth of wetland plants, these devices generally have the following problems: First, they cannot adaptively adjust the water level according to tidal changes, which may cause plants to be submerged due to excessively high water levels or lack of water due to excessively low water levels; second, when a certain area is raised due to siltation or low-lying areas are formed due to water erosion, they cannot flexibly adjust their position and height according to the topographical undulations of different areas. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a tidal wetland salt marsh plant growth promotion device, which effectively solves the problems of the prior art that it cannot adaptively adjust the water level according to tidal changes and cannot flexibly adjust the position and height according to the topographic undulations of different areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for promoting plant growth in tidal wetlands and salt marshes includes a frame. Inside the frame, a grid-like three-dimensional structure is formed by setting a first partition and a second partition to create independent planting troughs. A microporous aeration and oxygenation device, consisting of an air pump and an aeration pipe, is installed inside the planting trough. A water level regulation system is also installed inside the frame, including a water level monitoring module, a control module, and a water level regulation actuator. An installation and adjustment structure is also provided at the bottom of the frame to control the frame to maintain its movement in a parallel state with the water surface.

[0006] The installation and adjustment structure includes a mounting base. A first rotating rod is rotatably connected to the upper end of the mounting base. A rotating cylinder is fixedly connected to both ends of the first rotating rod. A support rod is slidably connected to the inner wall of the rotating cylinder. A second rotating rod parallel to the first rotating rod is also provided at the upper end of the mounting base. The support rod is provided at both ends of the second rotating rod. A connecting plate fixedly connected to the lower end of the frame is provided between the first rotating rod and the second rotating rod. A vertical shaft is fixedly installed on the mounting base. A first gear is fixedly installed inside the vertical shaft. L-shaped rods coaxial with the first gear are rotatably provided at both ends of the vertical shaft. A second gear driven by the chain of the first gear is provided at the bend of the L-shaped rod. The ends of the L-shaped rods are rotatably mounted on the second rotating rod. The second gear is coaxially fixedly mounted on the connecting plate.

[0007] A support plate is installed on the upper end of the frame, the air pump is installed on the support plate, the aeration pipe is set at the air outlet of the air pump, and the micropores of the aeration pipe are evenly arranged at both ends of the first partition to blow air into different planting troughs.

[0008] The water level monitoring module uses a high-precision ultrasonic water level sensor, which is set at different heights on the mounting plate at one end of the frame to monitor tidal water level changes in real time. The control module is a microprocessor, which is set in a water-proof protective box at the upper part of the first and second partitions. It is used to receive the data transmitted by the water level monitoring module and compare and analyze it with the preset water level threshold.

[0009] The water level regulating actuator includes a rotor pump mounted on a mounting plate. The drain pipe of the rotor pump is mounted on a second partition plate, and the second partition plate is provided with an irrigation port communicating with the planting trough. The end of the inlet pipe of the rotor pump is located in a nearby tidal wetland.

[0010] A submersible motor is mounted on the mounting base. A worm gear is fixedly connected to the output end of the submersible motor. The worm gear meshes with a worm wheel. A driving bevel gear is coaxially and fixedly connected to the worm wheel and rotatably connected to the mounting base. The driving bevel gear meshes with a driven bevel gear. The driven bevel gear is fixedly mounted on the first rotating rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The water level monitoring module uses a high-precision ultrasonic water level sensor, which is installed at different heights of the main frame to monitor tidal water level changes in real time. The control module is a microprocessor that receives the data from the water level monitoring module and compares it with the preset water level threshold. When the water level is higher than the set upper threshold, the control module controls the rotor pump in the water level adjustment actuator to start, discharging the excess water into the surrounding wetland environment. When the water level is lower than the set lower threshold, the rotor pump draws water from the surrounding wetland, and the second partition is equipped with an irrigation port connected to the planting trough to replenish the water into the planting trough, thereby realizing adaptive water level adjustment.

[0012] 2. By keeping the connecting plate parallel to the ground at all times, the connecting plate drives the frame to move horizontally and change height. This allows the device to flexibly adjust its position and height according to the terrain undulations of different areas. Through horizontal movement, the device can move between different areas, making full use of the limited high-quality growth space in tidal wetlands. Combined with height changes, it can accurately match the water level conditions of different areas and rationally allocate resources such as nutrient solution and light. Attached Figure Description

[0014] like Figure 1-6 As shown, a device for promoting the growth of plants in tidal wetlands and salt marshes includes a frame 1. Inside the frame 1, a grid-like three-dimensional structure is formed by setting a first partition 8 and a second partition 9 to create independent planting troughs. A microporous aeration and oxygenation device is installed in the planting trough, consisting of an air pump 5 and an aeration pipe 27. A water level regulation system is also installed inside the frame 1, which includes a water level monitoring module, a control module, and a water level regulation actuator. An installation and adjustment structure is also provided at the bottom of the frame 1 to control the frame 1 to maintain its parallel movement with the water surface.

[0015] In use, different plants are planted in different planting troughs. A permeable plate 11 is installed at the bottom of each planting trough, allowing water to enter and facilitating root development. A microporous aeration device, powered by an air pump 5, supplies oxygen to the different planting troughs via an aeration pipe 27, promoting plant growth. A water level detection module monitors tidal water level changes in real time. A control module receives data from the detection module and compares it with a preset water level threshold. When the water level exceeds the upper limit threshold, the control module activates a water level adjustment mechanism to discharge excess water into the surrounding wetland environment. When the water level falls below the upper limit threshold... When the lower limit threshold is set, the water level control mechanism operates, drawing water from the surrounding wetlands and replenishing the planting trough to achieve adaptive water level adjustment. For example, "based on the suitable flooding depth (0-30cm) for salt marsh plants (such as Spartina alterniflora), the upper limit threshold is preset to 30cm and the lower limit threshold to 5cm." Different thresholds can be set for different types of plants. Due to the complex and variable topography, water level, and water flow conditions of tidal wetlands, the horizontal movement and height variation of the control frame 1, achieved by using the installation adjustment structure, allows the device to flexibly adjust its position and height according to the topographical undulations of different areas. Through horizontal movement, the device can move between different areas, making full use of the limited high-quality growth space in tidal wetlands. Combined with height variations, it can accurately match the water level conditions of different areas and rationally allocate resources such as nutrient solution and light.

[0016] The installation and adjustment structure includes a mounting base 10. A first rotating rod 30 is rotatably connected to the upper end of the mounting base 10. A rotating cylinder 13 is fixedly connected to both ends of the first rotating rod 30. A support rod 14 is slidably connected to the inner wall of the rotating cylinder 13. A second rotating rod 29 parallel to the first rotating rod 30 is also provided at the upper end of the mounting base 10. The support rod 14 is provided at both ends of the second rotating rod 29. A connecting plate 19 fixedly connected to the lower end of the frame 1 is provided between the first rotating rod 30 and the second rotating rod 29. A vertical shaft 20 is fixedly installed on the mounting base 10. A first gear 17 is fixedly installed inside the vertical shaft 20. L-shaped rods 15 coaxial with the first gear 17 are rotatably provided at both ends of the vertical shaft 20. A second gear 18 is provided at the bend of the L-shaped rod 15 and is driven by the chain 16 of the first gear 17. The ends of the L-shaped rods 15 are rotatably provided on the second rotating rod 29. The second gear 18 is coaxially fixedly provided on the connecting plate 19.

[0017] like Figure 1 and 3 As shown in Figure 4, the first rotating rod 30 at the upper end of the mounting base 10 performs a self-locking deflection. During the rotation of the first rotating rod 30, it drives the rotating cylinders 13 at both ends to deflect. The rotating cylinders 13 correspondingly drive the support rod 14 to deflect synchronously. During the deflection of the support rod 14, it drives the second rotating rod 29 to swing. The second rotating rod 29 synchronously drives the L-shaped rods 15 at both ends to deflect around the connection point with the vertical shaft 20. During the deflection of the L-shaped rods 15, it drives the second gear 18 to deflect. Since the second gear 18 and the connecting plate 19 are coaxially fixedly connected, the second gear 18 drives the connecting plate 19 to deflect in position. However, since the position of the first gear 17 is fixed, Furthermore, the first gear 17 and the second gear 18 are driven by the chain 16. Therefore, as the connecting plate 19 deflects with the second gear 18, the second gear 18 rotates due to the action of the chain 16 and the first gear 17. The second gear 18 drives the connecting plate 19 to deflect in another direction, correcting the deflection direction and keeping the connecting plate 19 parallel to the ground. The connecting plate 19 drives the frame 1 to move horizontally and change height, allowing the device to flexibly adjust its position and height according to the terrain undulations of different areas. Through horizontal movement, the device can move between different areas, making full use of the limited high-quality growth space in tidal wetlands. Combined with height changes, it can accurately match the water level conditions of different areas and rationally allocate resources such as nutrient solution and light.

[0018] A support plate 4 is installed on the upper end of the frame 1, the air pump 5 is installed on the support plate 4, the aeration pipe 27 is set at the air outlet of the air pump 5, and the micropores 26 of the aeration pipe 27 are evenly arranged at both ends of the first partition 8 to blow air into different planting troughs.

[0019] like Figure 1 and 6 As shown, the support plate 4 supports the air pump 5. After the air pump 5 outputs air, it enters the aeration pipe 27 and is sprayed out through the microholes 26 evenly arranged on the first partition plate 8 to nourish the plants.

[0020] The water level monitoring module uses a high-precision ultrasonic water level sensor 3, which is set at different heights on the mounting plate 2 at one end of the frame 1 to monitor the tidal water level changes in real time. The control module is a microprocessor, which is set in the water-proof protective box set at the upper end of the first partition 8 and the second partition 9. It is used to receive the data transmitted by the water level monitoring module and compare and analyze it with the preset water level threshold.

[0021] The water level regulating actuator includes a rotor pump 6 mounted on the mounting plate 2. The outlet pipe 28 of the rotor pump 6 is mounted on the second partition 9. The second partition 9 is provided with an irrigation port 12 communicating with the planting trough. The end of the inlet pipe 7 of the rotor pump 6 is located in the nearby tidal wetland.

[0022] like Figure 1 As shown, the water level monitoring module uses a high-precision ultrasonic water level sensor 3, which is installed at different heights of the main frame 1 to monitor the tidal water level changes in real time. The control module is a microprocessor that receives the data from the water level monitoring module and compares and analyzes it with the preset water level threshold. When the water level is higher than the set upper threshold, the control module controls the rotor pump 6 in the water level adjustment actuator to start, discharging the excess water into the surrounding wetland environment. When the water level is lower than the set lower threshold, the rotor pump 6 draws water from the surrounding wetland. The second partition 9 is equipped with an irrigation port 12 that communicates with the planting trough to replenish the planting trough, thereby realizing the adaptive adjustment of the water level. The rotor pump 6 is suitable for water bodies containing impurities in tidal environments, and the rotor pump 6 can realize the exchange of suction and discharge through the forward and reverse rotation of the rotor.

[0023] A submersible motor 21 is mounted on the mounting base 10. A worm gear 22 is fixedly connected to the output end of the submersible motor 21. The worm gear 22 meshes with a worm wheel 25. The worm wheel 25 is coaxially fixedly connected to a driving bevel gear 24 that is rotatably connected to the mounting base 10. The driving bevel gear 24 meshes with a driven bevel gear 23. The driven bevel gear 23 is fixedly mounted on the first rotating rod 30.

[0024] like Figure 3-5 As shown, the submersible motor 21 is working. The output end of the submersible motor 21 drives the worm 22 to rotate. The worm 22 drives the worm wheel 25 to rotate. The worm wheel 25 drives the driving bevel gear 24 to rotate. The driving bevel gear 24 drives the driven bevel gear 23 to rotate. The driven bevel gear 23 drives the first rotating rod 30 to rotate.

[0025] The working process of this invention is as follows: When in use, different plants are planted in different planting troughs. By setting up a microporous aeration and oxygenation device, oxygen is supplied by an air pump 5 and discharged into different planting troughs through an aeration pipe 27, providing oxygen to the plants in the planting troughs and promoting plant growth. The function of "microporous aeration and oxygenation" is to increase the dissolved oxygen content of the water through tiny bubbles, promoting the respiration of plant roots. The water level monitoring module uses a high-precision ultrasonic water level sensor 3, which is installed at different heights of the main frame 1 to monitor the tidal water level changes in real time. The control module is a microprocessor that receives the data from the water level monitoring module and compares and analyzes it with the preset water level threshold. When the water level is higher than the set upper threshold, the control module controls the rotor pump 6 in the water level adjustment actuator to start, discharging the excess water into the surrounding wetland environment. When the water level is lower than the set lower threshold, the rotor pump 6 draws water from the surrounding wetland, and the second partition 9 is provided with an inlet 12 communicating with the planting trough to replenish the water into the planting trough, thereby realizing the adaptive adjustment of the water level.

[0026] Due to the complex and variable topography, water level, and water flow conditions of tidal wetlands, the submersible motor 21 operates. The output of the submersible motor 21 drives the worm gear 22 to rotate, which in turn drives the worm wheel 25 to rotate. The worm wheel 25 drives the driving bevel gear 24 to rotate, which in turn drives the driven bevel gear 23 to rotate. The driven bevel gear 23 drives the first rotating rod 30 at the upper end of the mounting base 10 to self-lock and deflect. During rotation, the first rotating rod 30 drives the rotating cylinders 13 at both ends to deflect, which in turn drives the support rod 14 to deflect synchronously. During deflection, the support rod 14 drives the second rotating rod 29 to swing, which in turn drives the L-shaped rods 15 at both ends to deflect around the connection point with the vertical shaft 20. During deflection, the L-shaped rods 15 drive the second gear 18 to deflect. Because the second gear 18 and... The connecting plate 19 is coaxially fixed, so the second gear 18 drives the connecting plate 19 to deflect its position. However, since the position of the first gear 17 is fixed, and the first gear 17 and the second gear 18 are transmitted through the chain 16, the connecting plate 19, as it deflects with the second gear 18, is affected by the chain 16 and the first gear 17, causing the second gear 18 to rotate. The second gear 18 drives the connecting plate 19 to deflect in another direction, correcting the deflection direction of the connecting plate 19 and keeping it parallel to the ground. The connecting plate 19 drives the frame 1 to move horizontally and change its height, allowing the device to flexibly adjust its position and height according to the terrain undulations of different areas. Through horizontal movement, the device can move between different areas, making full use of the limited high-quality growth space in tidal wetlands. Combined with height changes, it can accurately match the water level conditions of different areas and rationally allocate resources such as nutrient solution and light.
