Description

Technical Field

[0001] This invention relates to the field of ecological floating island technology, and more specifically, to a device and method for maintaining aquatic ecology. Background Technology

[0002] With the growth of the global population and the acceleration of industrialization, the protection of water resources and the maintenance of the ecological environment have become increasingly important.

[0003] Ecological floating islands, as floating platforms integrating various facilities and vegetation, are often used for the maintenance of aquatic ecosystems. The vegetation on these islands is a core component, capable of absorbing carbon dioxide, purifying the air, and adsorbing water pollutants. To ensure the water purification effect of ecological floating islands, it is necessary to monitor and record vegetation growth data, and promptly remove any vegetation affected by pests or diseases to prevent their spread.

[0004] However, existing ecological floating islands lack the necessary monitoring methods and cannot monitor the growth of vegetation. They rely on regular manual inspections, which makes it difficult to detect pests and diseases in a timely manner, easily leading to the spread of pests and diseases.

[0005] To address the difficulty in monitoring the maintenance of aquatic ecosystems using existing floating ecological islands, we propose an aquatic ecosystem maintenance device and method. Summary of the Invention

[0006] 1. The technical problems to be solved.

[0007] The purpose of this invention is to provide an aquatic ecological maintenance device and method to solve the problems mentioned in the background art.

[0008] 2. Technical solution.

[0009] An aquatic ecological maintenance device includes a water quality sensor, a planting tray, a water storage tray, a drainage component, a water injection component, a first float, and a lifting component. The lifting component is installed on the first float and is used to adjust the support height of the water storage tray on the water surface. The planting tray is installed on the upper part of the water storage tray. The drainage component is used to periodically drain the water stored in the water storage tray. The water injection component is used to inject water into the emptied water storage tray. The water quality sensor is used to monitor changes in the water quality in the water storage tray.

[0010] As an optional solution to the technical solution of this application, the water quality sensor is used to monitor the concentration of nutrients in the water in the water storage pan.

[0011] As an optional solution to the technical solution of this application, the lifting assembly includes a support frame, which is connected and fixed to a water storage pan. A plurality of limiting rods are fixedly connected to the support frame, and the limiting rods slide through a first float. A drive motor is installed on the first float, and a threaded rod is fixedly connected to the output end of the drive motor. The threaded rod is threadedly connected to the support frame.

[0012] As an optional solution to the technical solution of this application, the support frame is disposed below the water storage pan.

[0013] As an optional solution to the technical solution of this application, the drainage component includes a drainage trough formed at the bottom of the water storage pan, a limiting rod fixedly connected to the bottom of the water storage pan, and a second float slidably connected to the limiting rod. The second float is located below the drainage trough and is used to block the drainage trough.

[0014] As an optional solution to the technical solution of this application, the water injection assembly includes a water injection pipe, which is fixedly installed on a water storage pan and located below the water surface. The lower part of the water injection pipe has a water outlet. A piston is slidably inserted inside the water injection pipe to block the water outlet. A first support rod is rotatably connected to the outer end of the piston. A third float is fixedly connected to the other end of the first support rod. A second support rod is rotatably connected to the middle part of the first support rod and is rotatably connected to the lower part of the water injection pipe.

[0015] As an optional solution to the technical solution of this application, a shielding ring is fixedly provided on the upper part of the water storage tray, and the shielding ring protrudes upward from the planting tray to block floating objects on the water surface.

[0016] As an optional solution to the technical solution of this application, the planting tray is provided with multiple planting grooves, which are hollowed out.

[0017] As an optional solution to the technical solution of this application, the water storage pan is provided with an installation cavity that faces downwards, and the water injection component is installed in the installation cavity.

[0018] A method for maintaining aquatic ecosystems includes the following steps.

[0019] A water storage pan is used to isolate part of the water body.

[0020] The vegetation in the planting tray is used to purify the water in the water storage tray.

[0021] The initial nutrient concentration of the water in the water storage pan is measured using a water quality sensor.

[0022] After the set time, the nutrient concentration in the water storage pan is measured again using a water quality sensor, and the water in the water storage pan is replaced.

[0023] Calculate the difference between the nutrient concentrations measured twice by the water quality sensor.

[0024] When the difference between nutrient concentrations falls below a set threshold, a notification is sent using wireless communication technology.

[0025] 3. Beneficial effects.

[0026] Compared with the prior art, the advantages of the present invention are as follows.

[0027] 1. This application, by setting up drainage and water injection components, regularly replaces the water in the water storage tray, enabling the water quality sensor to monitor the nutrient content of the water in the water storage tray, obtain the purification efficiency of the vegetation in the planting tray, reflect the growth status of the vegetation, and promptly detect abnormal conditions of the vegetation in the planting tray, which is beneficial for controlling pests and diseases.

[0028] 2. This application uses a second float to block the drainage channel. When the water storage pan is lifted upward using the lifting component, the water in the water storage pan can be automatically discharged under the action of gravity. This drainage method can discharge the impurities deposited at the bottom of the water storage pan and the roots that have fallen off the vegetation, preventing the growth of pathogens in the water storage pan and thus limiting the growth of vegetation.

[0029] 3. This application uses a third float to drive the piston. After the water storage pan is emptied, it can automatically inject water into the water storage pan and control the water level in the water storage pan when it moves downward with the help of the lifting component. No manual intervention is required. It can also prevent the roots of the plants in the planting pan from being over-immersed in water, which would lead to root hypoxia and affect the growth of the plants. Attached Figure Description

[0035] Example 1.

[0036] Please see Figure 1 This invention provides an aquatic ecological maintenance device, including a water quality sensor 1, a planting tray 2, a water storage tray 3, a drainage component 4, a water injection component 5, a first float 6, and a lifting component 7. The lifting component 7 is installed on the first float 6 and is used to adjust the support height of the water storage tray 3 on the water surface. The planting tray 2 is installed on the upper part of the water storage tray 3. The drainage component 4 is used to periodically drain the water stored in the water storage tray 3. The water injection component 5 is used to inject water into the emptied water storage tray 3. The water quality sensor 1 is used to monitor changes in the water quality in the water storage tray 3.

[0037] In this embodiment, vegetation is planted in planting tray 2, which is then installed on water storage tray 3. Lifting component 7 supports water storage tray 3 on the water surface. Water is injected into water storage tray 3 using water injection component 5, submerging the plant roots. According to a set time, drainage component 4 is periodically controlled to empty the water in water storage tray 3, and water is then re-injected into water storage tray 3 using water injection component 5. During this process, drainage component 4 continuously monitors the water quality in water storage tray 3 during injection and drainage. When the vegetation in planting tray 2 suffers from pests or diseases, its water purification effect will decrease. Water quality sensor 1 monitors changes in water quality in water storage tray 3, obtaining the purification efficiency of the vegetation in planting tray 2 and indirectly reflecting the growth information of the vegetation in planting tray 2. When pests or diseases occur in the vegetation in planting tray 2, they can be detected promptly, enabling the monitoring of vegetation on the ecological floating island.

[0038] Water quality sensor 1 is used to monitor the concentration of nutrients in the water in the water storage pan 3. On the one hand, nutrients such as nitrogen and phosphorus are one of the main causes of eutrophication of water bodies. By regularly monitoring the nitrogen and phosphorus content in the water, the absorption and purification effect of nutrients by the ecological floating island can be evaluated. On the other hand, when vegetation suffers from pests and diseases, the ability of the vegetation roots to absorb nutrients from the water is gradually lost. Monitoring the changes in the concentration of nutrients in the water in the water storage pan 3 can reflect the growth status of the vegetation.

[0039] Please see Figure 2The lifting assembly 7 includes a support frame 701, which is connected and fixed to the water storage pan 3. Multiple limiting rods 702 are fixedly connected to the support frame 701. The limiting rods 702 slide through the first float 6. A drive motor 703 is installed on the first float 6. A threaded rod 704 is fixedly connected to the output end of the drive motor 703. The threaded rod 704 is threadedly connected to the support frame 701.

[0040] In this embodiment, as the vegetation in the planting tray 2 grows, the weight of the device will continuously increase, and the length of the first float 6 submerged in water will also increase, causing the position of the water storage tray 3 relative to the water surface to drop. By controlling the rotation of the threaded rod 704 through the drive motor 703, the support frame 701 is driven to move upward, raising the height of the water storage tray 3, preventing the water storage tray 3 from sinking into the water, and avoiding excessive immersion of the plant roots in the planting tray 2 in the water, which could cause root suffocation, root rot, and other problems.

[0041] To increase the stability of the device on the water surface, the support frame 701 can be placed below the water storage pan 3 to lower the center of gravity of the device.

[0042] Please see Figure 3 The drainage component 4 includes a drainage trough 401 formed at the bottom of the water storage pan 3. A limiting rod 402 is fixedly connected to the bottom of the water storage pan 3. A second float 403 is slidably connected to the limiting rod 402. The second float 403 is located below the drainage trough 401 and is used to block the drainage trough 401.

[0043] In this embodiment, when it is necessary to drain the water in the water storage pan 3, the lifting component 7 can be used to first control the water storage pan 3 to move upward so that the water storage pan 3 is completely above the water surface. Under the action of gravity, the second float 403 moves downward relative to the drainage channel 401, opening the drainage channel 401, and the water in the water storage pan 3 can be drained downward through the drainage channel 401. Then, the water storage pan 3 is controlled to move downward to reset, and the second float 403 will slide upward along the limit rod 402 under the action of buoyancy, blocking the drainage channel 401, thereby emptying the water in the water storage pan 3.

[0044] Please see Figure 4 The water injection assembly 5 includes a water injection pipe 501, which is fixedly installed on the water storage pan 3. The water injection pipe 501 is located below the water surface and has a water outlet 502 at its lower part. A piston 503 is slidably inserted inside the water injection pipe 501. The piston 503 is used to block the water outlet 502. A first support rod 504 is rotatably connected to the outer end of the piston 503. A third float 505 is fixedly connected to the other end of the first support rod 504. A second support rod 506 is rotatably connected to the middle of the first support rod 504. The second support rod 506 is rotatably connected to the lower part of the water injection pipe 501.

[0045] In this embodiment, after the water storage pan 3 is emptied, the third float 505 will move downwards under the action of gravity. The first support rod 504 can pull the piston 503 outwards, opening the outlet 502, allowing external water to be injected into the water storage pan 3 through the water inlet pipe 501 and the outlet 502. When the water level in the water storage pan 3 rises, it will push the third float 505 upwards, and the first support rod 504 can push the piston 503 inwards to block the outlet 502, limiting the water level in the water storage pan 3 and controlling the length of the plant roots in the planting pan 2 that are submerged in water.

[0046] A shielding ring 301 is fixedly installed on the upper part of the water storage tray 3. The shielding ring 301 protrudes upward from the planting tray 2 to block floating objects on the water surface and prevent garbage in the water from being washed onto the planting tray 2 by the water flow, thus affecting the growth of vegetation in the planting tray 2.

[0047] The planting tray 2 has multiple planting troughs 201, which are hollowed out. The roots of the plants planted in the planting troughs 201 can extend through the planting troughs 201 into the water storage tray 3 to purify the water in the water storage tray 3.

[0048] The water storage tray 3 has a downward-facing mounting cavity 302, and the water injection component 5 is installed inside the mounting cavity 302. The mounting cavity 302 is used to block the roots of the plants in the planting tray 2, preventing the roots from adversely affecting the function of the water injection component 5.

[0049] Example 2.

[0050] This invention provides a method for maintaining aquatic ecosystems, which uses an aquatic ecosystem maintenance device disclosed in Example 1, and specifically includes the following steps.

[0051] Use water storage pan 3 to isolate part of the water body.

[0052] The vegetation in planting tray 2 is used to purify the water in water storage tray 3.

[0053] The initial nutrient concentration of the water in the water storage pan 3 is measured using water quality sensor 1.

[0054] After the set time, the nutrient concentration in the water storage pan 3 is measured again using water quality sensor 1, and the water in the water storage pan 3 is replaced.

[0055] Calculate the difference between the nutrient concentrations measured by water quality sensor 1 in two separate measurements.

[0056] When the difference between nutrient concentrations falls below a set threshold, a notification is sent using wireless communication technology.

[0057] In this embodiment, the water storage tray 3 isolates part of the water body in the water area, so that the purification effect of the vegetation in the planting tray 2 on the water quality can be quantified and measured, thereby reflecting the growth status of the vegetation in the planting tray 2. When using this method to maintain the aquatic ecology, the water quality sensor 1 monitors the concentration of nutrients in the water storage tray 3, which can promptly detect abnormal conditions of the vegetation in the planting tray 2, and is conducive to controlling pests and diseases.
