[0001] The present invention relates to the technical field of ecological restoration, and in particular to a tidal wetland salt marsh plant growth promotion device and an adaptive water level regulation system. Background Art

[0002] Tidal salt marsh ecosystems play a vital role in maintaining biodiversity, purifying water quality, and protecting against storm surges. However, due to factors such as human activities and climate change, the area of ​​tidal wetlands is shrinking, and salt marsh plant growth faces numerous challenges. Existing salt marsh plant cultivation methods rely heavily on natural environmental conditions and lack effective human intervention, making it difficult to ensure optimal plant growth in complex tidal environments.

[0003] At present, 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 high water levels or lack water due to low water levels; second, when the terrain of a certain area is elevated due to siltation, or low-lying areas appear due to water erosion, they cannot flexibly adjust their position and height according to the terrain undulations of different areas. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a tidal wetland salt marsh plant growth promotion device and an adaptive water level regulation system, which effectively solves the problems in the existing technology that the water level cannot be adaptively adjusted according to tidal changes and the position and height cannot be flexibly adjusted according to the terrain undulations in different areas.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A tidal wetland salt marsh plant growth promotion device and an adaptive water level regulation system, comprising a frame, wherein the frame has an independent planting trough formed inside by arranging a first baffle and a second baffle in a grid-like three-dimensional structure, wherein a microporous aeration and oxygenation device is arranged in the planting trough, which is composed of an air pump and an aeration pipe, and a water level regulation system is also arranged in the frame, wherein the water level regulation system includes a water level monitoring module, a control module and a water level regulation actuator, and an installation adjustment structure is also provided at the bottom of the frame, which can control the frame to maintain movement parallel to the water surface.

[0006] The cam is connected with the second end of the gear train to the first end, and the cam is connected with the first gear to the second end by the spring, and the cam is connected with the first gear to the second end by the spring.

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

[0008] The water level monitoring module adopts a high-precision ultrasonic water level sensor, which is set at different heights of the mounting plate set at one end of the frame to monitor the tidal water level changes in real time. The control module is a microprocessor, which is set in the waterproof protection box set at the upper ends of the first partition and the second partition 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 arranged on a mounting plate, a drainage pipe of the rotor pump is mounted on a second partition, an irrigation port communicating with a planting trough is provided on the second partition, and the end of the water inlet pipe of the rotor pump is arranged in a nearby tidal wetland.

The driving bevel gear is engaged with a driven bevel gear, and the driven bevel gear is fixedly mounted on the first rotating rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 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 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 limit threshold, the control module controls the rotor pump in the water level regulation actuator to start and discharge excess water into the surrounding wetland environment.

DETAILED DESCRIPTION

[0014] like Figure 1-6 As shown, a tidal wetland salt marsh plant growth promotion device and an adaptive water level regulation system include a frame 1. The frame 1 has an independent planting trough formed in a grid-like three-dimensional structure by arranging a first baffle 8 and a second baffle 9. The planting trough is provided with a microporous aeration and oxygenation device, which consists of an air pump 5 and an aeration pipe 27. The frame 1 is also provided with a water level regulation system, which includes a water level monitoring module, a control module and a water level regulation actuator. The bottom of the frame 1 is also provided with an installation and adjustment structure that can control the frame 1 to maintain movement parallel to the water surface.

[0015] When the present invention is in use, different plants are planted in different planting troughs. A permeable plate 11 is installed at the bottom of the planting trough. Water can enter the planting trough by using the permeable plate 11, and it is convenient for the development of the plant root system. By setting a microporous aeration and oxygenation device, an air pump 5 is used to supply oxygen, which is discharged into different planting troughs by an aeration pipe 27, so that oxygen is passed to the plants in the planting troughs to promote the growth of the plants. The water level detection module is used to detect the change of the tidal water level in real time. The control module receives the data sent by the detection module and compares and analyzes it with the preset water level threshold. When the water level is higher than the set upper limit threshold, the control module controls the water level adjustment actuator to work and discharge the excess water to the surrounding wetland environment. When the water level is lower than the set upper limit threshold, the control module controls the water level adjustment actuator to work and discharge the excess water to the surrounding wetland environment. When the set lower threshold is reached, the water level actuator activates, drawing water from the surrounding wetlands and replenishing it in the planting trough, achieving adaptive water level regulation. For example, based on the optimal flooding depth (0-30 cm) for salt marsh plants (such as Spartina alterniflora), the upper threshold is preset to 30 cm and the lower threshold to 5 cm. Different thresholds can be set for different plant types. Due to the complex and variable topography, water levels, and flow conditions in tidal wetlands, the installation adjustment structure controls the horizontal movement and height variation of frame 1, allowing the device to flexibly adjust its position and height based on the terrain of different areas. This horizontal movement allows the device to move between different areas, fully utilizing the limited high-quality growing space in tidal wetlands. Combined with height variations, it can accurately match water level conditions in different areas and rationally allocate resources such as nutrient solution and light.

[0016] The mounting adjustment structure includes a mounting base 10, the upper end of the mounting base 10 is rotatably connected to a first rotating rod 30, and both ends of the first rotating rod 30 are fixedly connected to a rotating drum 13, and the inner wall of the rotating drum 13 is slidably connected to a support rod 14. The upper end of the mounting base 10 is also provided with a second rotating rod 29 parallel to the first rotating rod 30, and the two ends of the second rotating rod 29 are respectively provided with the support rod 14, and 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, and a first gear 17 is fixedly provided in the vertical shaft 20. The two ends of the vertical shaft 20 are respectively rotatably provided with an L-shaped rod 15 coaxial with the first gear 17, and the bending part of the L-shaped rod 15 is provided with a second gear 18 transmitted by the chain 16 of the first gear 17. The ends of the L-shaped rod 15 are both rotatably provided on the second rotating rod 29, and the second gear 18 is coaxially fixed on the connecting plate 19.

[0017] like Figure 1 and 3 As shown in FIG4 , the first rotating rod 30 at the upper end of the mounting base 10 is self-lockingly deflected. During the rotation process, the first rotating rod 30 drives the rotating drum 13 at both ends to deflect respectively. The rotating drum 13 correspondingly drives the support rod 14 to deflect synchronously. During the deflection process, the support rod 14 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 with the connection with the vertical shaft 20 as the axis. During the deflection process, the L-shaped rod 15 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 the position. However, since the position of the first gear 17 is fixed, The first gear 17 and the second gear 18 are driven by the chain 16. Therefore, as the connecting plate 19 deflects the second gear 18, due to the action of the chain 16 and the first gear 17, the second gear 18 rotates, and the second gear 18 drives the connecting plate 19 to deflect in the other direction, which is used to correct the deflection direction of the connecting plate 19 and keep the connecting plate 19 always 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 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 the height change, 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 at the upper end of the frame 1, the air pump 5 is installed on the support plate 4, the aeration pipe 27 is arranged at the air outlet end 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 aerate different planting troughs.

[0019] like Figure 1 and 6 As shown, the support plate 4 supports the air pump 5. The air discharged from the air pump 5 enters the aeration pipe 27 and is ejected from the micropores 26 evenly arranged on the first partition plate 8 to nourish the plants.

[0020] The water level monitoring module adopts a high-precision ultrasonic water level sensor 3, which is set at different height positions of the mounting plate 2 set 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 waterproof protection box set at the upper ends of the first partition 8 and the second partition 9, and 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 arranged on the mounting plate 2, the outlet pipe 28 of the rotor pump 6 is installed on the second partition 9, the second partition 9 is provided with an irrigation port 12 communicating with the planting trough, and the end of the water inlet pipe 7 of the rotor pump 6 is arranged in a nearby tidal wetland.

[0022] like Figure 1 As shown, the water level monitoring module adopts a high-precision ultrasonic water level sensor 3, which is installed at different height positions of the main frame 1 to monitor the tidal water level changes in real time. The control module is a microprocessor, which 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 limit threshold, the control module controls the rotor pump 6 in the water level regulation actuator to start and discharge excess water to the surrounding wetland environment. When the water level is lower than the set lower limit threshold, the rotor pump 6 draws water from the surrounding wetland, and the second partition 9 is provided with an irrigation port 12 connected to the planting trough to supplement the water in the planting trough, thereby realizing adaptive adjustment of the water level. The rotor pump 6 can be suitable for water bodies containing impurities in a tidal environment, 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 , and a worm 22 is fixedly connected to the output end of the submersible motor 21 , and the worm 22 is meshed with a worm wheel 25 , and the worm wheel 25 is coaxially fixedly connected to a driving bevel gear 24 that is rotatably connected to the mounting base 10 , and the driving bevel gear 24 is meshed with a driven bevel gear 23 , and the driven bevel gear 23 is fixedly mounted on a 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 active bevel gear 24 to rotate, the active bevel gear 24 drives the driven bevel gear 23 to rotate, and the driven bevel gear 23 drives the first rotating rod 30 to rotate.

[0025] The working process of the present invention is as follows: when in use, the present invention is planted in different planting troughs. By setting up a microporous aeration and oxygenation device, an air pump 5 is used to supply oxygen, which is 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 in the water body through tiny bubbles, thereby 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 tidal water level changes in real time. The control module is a microprocessor that receives data from the water level monitoring module and compares and analyzes it with a 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 regulation actuator to start and discharge 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 provided with an inlet 12 connected to the planting trough to replenish the water into the planting trough, thereby achieving adaptive adjustment of the water level.

[0026] Due to the complex and changeable terrain, water level and water flow conditions of the tidal wetland, the submersible motor 21 works, the output end of the submersible motor 21 drives the worm 22 to rotate, the worm 22 drives the worm gear 25 to rotate, the worm gear 25 drives the active bevel gear 24 to rotate, the active bevel gear 24 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 perform self-locking deflection, the first rotating rod 30 drives the rotating drum 13 at both ends to deflect during the rotation process, the rotating drum 13 correspondingly drives the support rod 14 to deflect synchronously, the support rod 14 drives the second rotating rod 29 to swing during the deflection process, the second rotating rod 29 synchronously drives the L-shaped rods 15 at both ends to deflect with the connection with the vertical shaft 20 as the axis, and the L-shaped rod 15 drives the second gear 18 to deflect during the deflection process. 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 driven by the chain 16, the connecting plate 19 rotates as the second gear 18 deflects 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 the other direction, which is used to correct the deflection direction of the connecting plate 19 and keep the connecting plate 19 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 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 the height change, it can accurately match the water level conditions of different areas and rationally allocate resources such as nutrient solution and light.
