Description

Technical Field

[0001] This invention relates to the field of water body ecological restoration technology, specifically to a device for ecological restoration of slightly polluted wetland water bodies. Background Technology

[0002] Wetlands are areas where the surface is excessively wet or frequently stagnant with water, providing habitat for wetland organisms. Along with forests and oceans, they are considered one of the three major global ecosystems, possessing important ecological functions such as water conservation, water purification, and flood control, and are known as the "kidneys of the earth." Wetland water bodies are an important component of wetland ecosystems, including various types of water bodies such as rivers, lakes, marshes, and ponds within the wetland area. They are the foundation for the survival and reproduction of wetland organisms, and also play a crucial role in material cycling and energy flow.

[0003] Wetland ecosystems have limited self-regulation capabilities. When the input of external pollutants exceeds the ecosystem's capacity, water pollution occurs. Wetland water pollution is generally classified into three levels: slight pollution (micro-pollution), moderate pollution, and severe pollution. Slight pollution (micro-pollution) involves a chemical oxygen demand (COD) concentration of 15-30 mg / L, ammonia nitrogen concentration of 0.5-1.5 mg / L, and total phosphorus concentration of 0.05-0.1 mg / L. The pollutant levels are low and generally do not cause significant damage to the wetland ecosystem, but may affect the survival of some sensitive organisms. The water may appear slightly turbid or have an unusual odor, and dissolved oxygen levels may decrease slightly to 5-6 mg / L. Moderate pollution involves a COD concentration of 30-60 mg / L, ammonia nitrogen concentration of 1.5-3 mg / L, and total phosphorus concentration of 0.05-0.1 mg / L. When the concentration is 0.1-0.2 mg / L, the pollutant content in the water increases significantly, which will have a significant impact on the wetland ecosystem. The types and numbers of aquatic organisms will decrease significantly, some organisms may die or become deformed, the eutrophication of the water body will intensify, algae will proliferate, the water body will turn green or black, the odor will become stronger, and the dissolved oxygen content will be 3-5 mg / L, and even local hypoxia may occur. When the pollution is severe, the chemical oxygen demand (COD) concentration is >60 mg / L, the ammonia nitrogen concentration is >3 mg / L, and the total phosphorus concentration is >0.2 mg / L. The pollutant content in the water body is seriously exceeded, the wetland ecosystem is almost destroyed, most aquatic organisms die, the water body turns black and smells bad, the dissolved oxygen content is <3 mg / L, or even in an anaerobic state, the ecological function of the wetland is completely lost, and it may also pose a serious threat to the surrounding soil, air and human health. When wetland water bodies are in a state of slight pollution (micro-pollution), aerators are typically used to restore the wetland water body through aeration and oxygenation. For example, the RKTY-30 solar aerator consists of solar cell modules, a control system, aeration components, and a floating body component. The solar cell modules are responsible for converting solar energy into electrical energy to power the equipment. The control system is used to regulate energy output and the operating status of the equipment. The aeration components are mostly impellers or fountain mechanisms, which are the core components for agitating the water. The floating body component mainly provides stable floating support for the equipment, ensuring that the equipment can work normally on the water surface. Based on the theory of water reoxygenation cycle, the oxygen-deficient bottom sediment water is fully mixed with the oxygen-rich surface water through mechanical action, promoting the vertical and horizontal circulation and exchange of water, eliminating dissolved oxygen stratification. At the same time, the horizontal flow enhances the circulation and exchange of water, increases the dissolved oxygen content of the bottom water, improves the activity of microorganisms in the bottom sediment and water, accelerates the decomposition of organic matter, nitrogen, phosphorus and other nutrients in the water and bottom sediment, reduces secondary pollution of the water body caused by bottom sediment release, and thus achieves the restoration of wetland water bodies. In the actual use of the RKTY-30 solar aerator for wetland water body restoration, the depth of the aeration components entering the water body needs to be controlled in the middle and lower layers of the water body. This ensures that the anoxic water at the bottom layer is fully mixed with the oxygen-rich water at the surface layer, while preventing the aeration components from stirring up the bottom sediment. When the wetland water body is affected by rainfall, the water level changes. When the water level rises, the aeration components are rigidly connected to the floating components and rise synchronously with the floating components. This causes the aeration components to move from the middle and lower layers of the water body to the middle or upper layers, deviating from the original optimal working area in the middle and lower layers. This results in obstructed exchange between the anoxic water at the bottom layer and the nutrient-rich water at the surface layer, reducing the restoration efficiency. Conversely, when the water level drops, there is a risk of stirring up the bottom sediment.

[0004] Therefore, this invention proposes a micro-polluted wetland water ecological restoration device that can adapt to water level changes and maintain the optimal working depth of the aeration components, so as to ensure the continuity and stability of the restoration effect. Summary of the Invention

[0005] The micro-polluted wetland water ecological restoration device provided by the present invention sets a fixed rod at the bottom of the water body, allowing the bracket of the solar aerator to slide vertically with the fixed rod, and uses a fixed pulley and steel rope to connect the bracket and the aeration component, so as to automatically adjust the depth of the aeration component when the water level changes, so that it is always in the middle and lower layers of the water body, thereby improving the restoration effect.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A micro-polluted wetland water ecological restoration device, comprising a solar aerator consisting of a solar panel, a controller, an aeration panel, a support frame, and several floats, wherein the improvement is as follows: at least two vertically arranged fixed rods are fixedly connected to the bottom of the water body, the side of the support frame near the fixed rods is vertically slidably engaged with the corresponding fixed rod, a fixed plate is fixedly connected to the support frame, a fixed cylinder is fixedly connected to the bottom of the fixed plate, a connecting rod is slidably engaged inside the fixed cylinder, the bottom end of the connecting rod is fixedly connected to the aeration panel, a fixed pulley is fixedly connected to the upper part of the fixed rod, a steel rope is slidably engaged on the fixed pulley, one end of each of the two steel ropes is fixedly connected to both sides of the support frame, and the other end of each steel rope passes through the fixed plate and extends into the fixed cylinder and is fixedly connected to the top of the connecting rod.

[0007] The technical principle of the above solution is as follows: When the water level rises, the float rises with the water level, causing the support to slide upward along the fixed rod. When the support moves upward, it pulls the steel cable through the fixed pulley. The steel cable releases its length at the end of the connecting rod. At this time, the weight of the aeration component and the connecting rod applies tension to the other end of the steel cable, causing the aeration component to move downward. This keeps the aeration component in the middle and lower layers of the water body, effectively compensating for the height of the water level rise. Conversely, when the water level drops, the support slides downward with the float, and the steel cable tightens, applying an upward tension to the aeration component and the connecting rod, maintaining a suitable working depth. The entire process is completed automatically by machine, without the need for external power or manual intervention, ensuring that the aeration component remains stable in the middle and lower layers of the water body, maintaining continuous exchange between the upper and lower layers of the water body, and improving the restoration effect.

[0008] The above approach has the following beneficial effects: 1. This solution automatically adjusts the depth of the aeration components according to changes in water level, ensuring that the aeration components are always located in the lower and middle layers of the water body, so that the oxygen-deficient water at the bottom layer is fully mixed with the oxygen-rich water at the surface layer, thereby improving the effect of the aeration components on water body restoration. 2. This solution improves the continuity of the repair process by adaptively adjusting the position of the aeration components, eliminating the need for frequent manual adjustments to the depth of the aeration components.

[0009] Furthermore, the connecting rod sidewall is fixedly connected with symmetrically arranged sliders, and the inner sidewall of the fixed cylinder is provided with several limiting grooves corresponding to the sliders along its axial direction. The limiting grooves and the corresponding sliders slide vertically together.

[0010] Beneficial effects: This structure effectively prevents the connecting rod and aeration components from rotating in the water flow, ensuring stable operation and effectively controlling the height.

[0011] Furthermore, a water quality monitoring sensor is installed at the bottom of the bracket, and the water quality monitoring sensor is electrically connected to the controller.

[0012] Beneficial effects: By monitoring water quality data such as dissolved oxygen, pH, and ammonia nitrogen through water quality monitoring sensors, the controller can dynamically adjust the operating power of the aeration components based on the water quality data, thereby achieving precise remediation.

[0013] Furthermore, a buffer pad is fixedly connected to the top wall of the fixed cylinder.

[0014] Beneficial effect: When the water level drops sharply, it can buffer the impact of the rising connecting rod and protect the structure.

[0015] Furthermore, the steel ropes are all coated with an anti-corrosion coating.

[0016] Beneficial effects: The anti-corrosion coating prevents the steel rope from rusting and corroding, improves the strength and service life of the steel rope, ensures that the steel rope can stably withstand tension during long-term use, and guarantees the normal operation of the lifting function of the device.

[0017] Furthermore, all fixed pulleys are equipped with dust covers.

[0018] Beneficial effects: The dust cover prevents dust, mud, and other contaminants from entering the fixed pulley, reducing wear on the fixed pulley and ensuring smooth sliding of the steel rope on the fixed pulley.

[0019] Furthermore, the surfaces of the fixed pulleys are all coated with polytetrafluoroethylene.

[0020] Beneficial effects: By utilizing the low-friction properties of polytetrafluoroethylene (PTFE), the friction between the steel rope and the fixed pulley is reduced, making the steel rope slide more smoothly, reducing energy loss, and at the same time reducing the wear of the steel rope and the fixed pulley, extending their service life, and improving the smoothness and reliability of the device operation.

[0021] Furthermore, a meteorological monitoring instrument is installed at the top of the support frame, and the meteorological monitoring instrument is electrically connected to the controller.

[0022] Beneficial effects: The weather monitoring instrument monitors meteorological information such as wind speed, wind direction, and rainfall in real time. The controller adjusts the operating power of the aeration components according to the meteorological information, thereby improving energy efficiency and adaptability.

[0023] Furthermore, a water level sensor is installed at the bottom of the float, and the water level sensor is connected to the controller signal.

[0024] Beneficial effects: By monitoring water level changes in real time through water level sensors and combining water level change information with aeration component operation data, managers can better understand the water change trends in relevant areas and provide more detailed data support for water body restoration.

[0025] Furthermore, a warning light is installed on the top of the bracket, and the warning light is connected to the controller signal.

[0026] Beneficial effects: The controller automatically turns on the warning lights at night, emitting a conspicuous warning signal to prevent ships or water-based equipment from accidentally colliding with the device, thus improving the safety of nighttime operations. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The following detailed description illustrates the specific implementation method: Example 1:

[0033] As attached Figure 1 As shown: A micro-polluted wetland water ecological restoration device includes a solar aerator (designed with reference to the RKTY-30 solar aerator) consisting of a solar panel 12, a controller, an aeration panel 11, a support 2, and several floats 1. Since the aeration panel 11 and the support 2 are usually rigidly connected, when the water level rises due to rainfall or other reasons, the aeration panel 11 rises synchronously with the floats 1, causing the aeration panel 11 to move from the lower and middle layers of the original water body to the middle or even upper layers of the current water body. This causes the aeration device to deviate from the original optimal working area in the lower and middle layers, hindering the exchange between the oxygen-deficient water at the bottom layer and the oxygen-rich water at the surface layer, thus reducing the restoration efficiency. When the water level drops, the aeration panel falls with the floats, posing a risk of stirring up the bottom sediment, thereby reducing the restoration effect on the water body. To ensure that the aeration component 11 is located in the lower layer of the water body, thereby improving the remediation effect, as shown in the attached... Figure 1 and attached Figure 2 As shown, the bottom anchor of the water body has at least two vertically arranged fixed rods 3. The side of the bracket 2 closest to the fixed rod 3 is vertically slidably engaged with the corresponding fixed rod 3 through a sliding groove rail. A fixed plate 4 is fixedly connected to the bracket 2 by bolts. A fixed cylinder 5 is fixedly connected to the bottom of the fixed plate 4 by bolts. A connecting rod 6 is slidably engaged inside the fixed cylinder 5. The bottom end of the connecting rod 6 is fixedly connected to the aeration component 11. Fixed pulleys 7 are fixedly connected to the upper part of the fixed rods 3 on their adjacent sides by bolts. Steel ropes 8 are slidably engaged on the fixed pulleys 7 (the surface of the steel ropes 8 is coated with an anti-corrosion coating to prevent the steel ropes 8 from rusting and corroding, and to lift the steel ropes). The strength and service life of the rope 8 ensure that the steel rope 8 can stably withstand the tension during long-term use. The surface of the fixed pulley 7 is coated with polytetrafluoroethylene. The low friction characteristics of polytetrafluoroethylene reduce the friction between the steel rope 8 and the fixed pulley 7, making the steel rope 8 slide more smoothly. The fixed pulley 7 is equipped with a dust cover to prevent dust, mud and sand from entering the interior of the fixed pulley 7, ensuring that the steel rope 8 slides smoothly on the fixed pulley 7. One end of each of the two steel ropes 8 is fixedly connected to both sides of the bracket 2 by bolts. The other end of each steel rope 8 passes through the fixed plate 4 and extends into the fixed cylinder 5 and is fixedly connected to the top of the connecting rod 6 by bolts. The connecting rod 6 is fixedly connected to the side wall of a symmetrically arranged slider 9 by bolts. The inner side wall of the fixed cylinder 5 has several limiting grooves 10 corresponding to the slider 9 along its axial direction. The limiting grooves 10 and the corresponding slider 9 slide vertically together. A buffer pad is bonded to the top inner wall of the fixed cylinder 5. When the water level drops sharply, the buffer pad buffers the impact force of the connecting rod 6 rising and protects the structure.

[0034] The specific implementation process is as follows: In the initial state, the aeration component 11 is located in the lower layer of the water body, which enables the low-oxygen water at the bottom to fully exchange with the high-oxygen water on the surface, ensuring the dissolved oxygen content of the bottom water body, improving the oxygen transfer effect, and thus ensuring the water body restoration effect; however, when the water level rises due to rainfall or other reasons, the aeration component 11 is rigidly connected to the support 2, and the aeration component 11 will rise synchronously with the float 1, moving from the original lower layer of the water body to the current middle layer or even the upper layer of the water body, causing the aeration device to deviate from the original optimal working area in the lower layer, the low-oxygen water at the bottom and the high-oxygen water on the surface cannot fully exchange, the dissolved oxygen content of the bottom water body decreases, oxygen transfer is blocked, and the water body restoration efficiency decreases accordingly; To address this issue, this device maintains the aeration component 11 in the lower layers of the water to enhance the remediation effect. When the water level rises, the float 1 rises with the water level and drives the support 2 to slide upwards along the height of the fixed rod 3. As the support 2 moves upwards, the tension on the end of the steel rope 8 connected to the support 2 decreases due to increased buoyancy. The fixed pulley 7 pulls the steel rope 8 to release its length at the end of the connecting rod 6. At this time, the weight of the aeration component 11 and the connecting rod 6 exerts a downward pull on the steel rope 8, causing it to slide around the fixed pulley 7 and pull the connecting rod 6 downwards within the fixed cylinder 5. (See attached diagram.) Figure 4 As shown, after the water level rises, the connecting rod 6 drives the aeration component 11 to descend synchronously; at the same time, the limiting groove 10 guides and constrains the slider 9, preventing the connecting rod 6 from deviating during sliding, ensuring that the aeration component 11 can move stably, keeping the aeration component 11 always in the middle and lower layers of the water body, effectively compensating for the height of the water level rise, continuously aerating the middle and lower layers of the water body, promoting full exchange between the low-oxygen water at the bottom and the high-oxygen water at the surface, ensuring the dissolved oxygen content of the bottom water body, improving the oxygen transfer effect, and thus improving the water body remediation efficiency; at the same time, because the aeration component 11 is in a stable position, it can avoid the agitation of bottom sediment caused by improper positioning, reducing secondary pollution of the water body caused by bottom sediment release; When the water level drops, the buoyancy of the float 1 decreases, and the support 2 slides downward along the fixed rod 3 with the float 1. The end of the steel rope 8 connected to the support 2 is pulled downward by the weight of the support 2 and the float 1. The steel rope 8 is taut and applies an upward pulling force to the top of the connecting rod 6, causing the connecting rod 6 to slide upward inside the fixed cylinder 5. The slider 9 slides upward inside the limiting groove 10 to ensure the stability of the sliding of the connecting rod 6. When the connecting rod 6 rises to contact the top wall of the fixed cylinder 5, the buffer pad on the top wall of the fixed cylinder 5 absorbs the impact force to prevent the connecting rod 6 from directly colliding with the fixed cylinder 5 and causing damage, thus extending the service life of the device. At this time, the aeration component 11 moves upward with the connecting rod 6 and remains in the middle and lower layers of the water body to continue to achieve full exchange between the low-oxygen water at the bottom and the high-oxygen water at the surface, maintain the dissolved oxygen content of the bottom water, and ensure the oxygen transfer effect and water body restoration effect. This device anchors a vertically fixed rod at the bottom of the water body, allowing the support frame to slide vertically with the fixed rod. Combined with the sliding structure of the fixed cylinder and connecting rod, this forms a stable vertical adjustment system. Simultaneously, the cooperation of the slider and the limiting groove strictly constrains the sliding trajectory of the connecting rod, preventing deviation and ensuring the stable operation of the aeration component. The buffer pad on the top wall of the fixed cylinder can buffer the impact force of the connecting rod rising when the water level drops sharply, effectively protecting structural components and further enhancing overall height stability and impact resistance. This provides core structural protection for ensuring the aeration component remains in the lower layers of the water body. The surface of the fixed pulley is coated with polytetrafluoroethylene. The first layer, with its low-friction characteristics, significantly reduces the friction between the steel rope and the pulley, making the steel rope slide more smoothly, reducing wear on both, and extending service life. The anti-corrosion coating on the surface of the steel rope effectively prevents rust and corrosion, and can withstand tension stably for a long time, ensuring normal lifting function. The dust cover on the fixed pulley can prevent dust and silt from entering the interior, reducing pulley wear and ensuring smooth steel rope sliding, comprehensively improving the durability of the device in the complex water environment of wetlands. The entire process is completed automatically by pure machinery without external power or manual intervention, ensuring that the aeration components are always stable in the lower layer of the water, maintaining continuous exchange between the upper and lower layers of the water, and improving restoration efficiency.

[0035] Example 2:

[0036] As attached Figure 1 and attached Figure 5As shown, the difference from Embodiment 1 is that a water quality monitoring sensor is provided at the bottom of the support 2 where it contacts the water, and a meteorological monitor and a warning light are provided at the top of the support 2. The water quality monitoring sensor, the meteorological monitor, and the warning light are all electrically connected to the controller. A water level sensor is provided at the bottom of the float 1, and the water level sensor is connected to the controller signal. The preferred model of the water quality monitoring sensor is the Eureka Manta2 multi-parameter water quality monitor, the preferred model of the meteorological monitor is the Vaisala WXT530 meteorological sensor, the preferred model of the warning light is the Werma 829.010.010 solar LED warning light, and the preferred model of the water level sensor is the SIEMENS Sitrans L ultrasonic water level sensor.

[0037] The specific implementation process is as follows: the dissolved oxygen, pH value, ammonia nitrogen and other indicators of the water body are monitored in real time by water quality monitoring sensors, and meteorological information such as wind speed, wind direction and rainfall are monitored in real time by meteorological monitoring instruments. The operating power of the aeration component 11 is dynamically adjusted according to the monitored water quality data and meteorological information to achieve refined restoration, and at the same time, it is convenient for managers to keep abreast of the water body restoration status. The water level sensor monitors water level changes in real time and combines the water level change information with the operation data of the aeration component 11, which makes it easier for managers to understand the water change trend in the relevant area and provides more detailed data support for water body restoration. At night (preset nighttime period), the warning lights are automatically turned on by the controller to emit a conspicuous warning signal, preventing ships or water-based equipment from accidentally colliding with the device and improving nighttime operation safety.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
