Description

Technical Field

[0001] The present invention belongs to the technical field of water ecological restoration, and in particular relates to a water ecological environment restoration system based on the background of climate change. Background Art

[0002] In the field of water ecological environment restoration, there are currently a variety of technical methods aimed at improving and restoring damaged aquatic ecosystems. These technologies include but are not limited to phytoremediation, bioremediation, physical remediation, chemical remediation and engineering remediation. For example, phytoremediation achieves the purpose of purifying water quality by utilizing the absorption, transformation and degradation of pollutants in water bodies by plants. Bioremediation utilizes the metabolic capacity of microorganisms or aquatic plants to decompose and remove harmful substances in water bodies. In addition, there are physical and chemical methods such as aeration, filtration, sedimentation and oxidation-reduction to remove pollutants such as particulate matter, suspended matter, dissolved matter and heavy metals from water bodies. Engineering remediation includes the construction of engineering facilities such as wetlands and aquaculture ponds, which utilize the self-purification capacity of their ecosystems and the metabolic effects of organisms to further remove pollutants in water bodies.

[0003] Although the above technologies have achieved certain results in the restoration of aquatic ecological environment, they also have their own shortcomings. For example, although phytoremediation has a low cost, the restoration cycle is long and needs to be used in conjunction with other engineering technologies. Biological remediation may be affected by environmental conditions such as temperature and pH value, resulting in unstable restoration effects. Physical and chemical methods may require a large amount of energy and chemical reagents, which is not only costly, but may also cause secondary pollution to the environment. Engineering remediation may be limited by factors such as geographical location and capital investment, and it is difficult to promote and implement in all waters. In addition, these technologies often find it difficult to achieve ideal restoration effects in complex and changing climate environments. Summary of the invention

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1

[0031] like Figure 1-7 As shown, this embodiment proposes a water ecological environment restoration system based on the background of climate change, including a multi-level ecological floating island 100, a water quality monitoring module 200 and five intelligent delivery modules 300; the multi-level ecological floating island 100 is composed of four floating island units 2 and a cross 4; wherein the four floating island units 2 are respectively fixedly arranged at four vertical angles of the cross 4, and are configured to cultivate aquatic plants; the water quality monitoring module 200 is located in the space below the floating island unit 2, and is configured to obtain the water temperature index and specific water quality index of the target water area, and send a first control signal when the water temperature index exceeds a preset threshold, and send a delivery signal when at least one of the specific water quality indicators exceeds a preset threshold; wherein the specific water quality index includes at least one of pH value, dissolved oxygen, nitrogen and phosphorus content and heavy metal content; the intelligent delivery module 300 is respectively arranged at the four ends and the center of the cross 4, and is configured to respond to the delivery signal to deliver microbial strains to the target water area; wherein a driving component is provided in the floating island unit 2, for responding to the first control signal to drive adjacent floating island units 2 to move away from each other for heat dissipation.

[0032] like Figure 1and Figure 2 As shown, the multi-level ecological floating island 100 of the present invention is composed of four floating island units 2 and a cross 4. The four floating island units 2 are fixedly arranged at four vertical angles of the cross to form a stable structure. The floating island unit 2 is provided with at least two rows of parallel through holes 5 and a planting tube 6 penetrating the through holes. The planting tube 6 extends at least ten centimeters below the water body for planting aquatic plants, such as lotus, reed, etc. These aquatic plants can absorb nutrients in the water, purify the water quality, and provide a habitat for aquatic organisms.

[0033] The water quality monitoring module 200 in the present invention is located in the space below the floating island unit, and includes a controller unit 201 and a sensor unit 202. The sensor unit 202 is used to obtain the water temperature index and specific water quality index of the target water area, such as pH value, dissolved oxygen, nitrogen and phosphorus content, heavy metal content, etc. When the water temperature index exceeds the preset threshold, the controller unit 201 sends a first control signal; when at least one of the specific water quality indexes exceeds the preset threshold, the controller unit 201 sends a release signal. In addition, the controller unit 201 also has an intelligent judgment function. When the difference between the water temperature at either end of the cross and the water temperature at the center of the cross exceeds the set threshold, or any one or more of the water temperature at either end of the cross and the water temperature at the center of the cross exceeds the set threshold, a first control signal is sent (when the water temperature at the end of the cross 4 is too high and forms a large temperature difference with the center, it means that the area may be affected by excessive sunlight or other heat sources); otherwise, a second control signal is sent (at this time, the difference between the water temperature at either end of the cross and the water temperature at the center of the cross does not exceed the set threshold, or any one or more of the water temperature at either end of the cross and the water temperature at the center of the cross does not exceed the set threshold).

[0034] It is understandable that when the recovery system of the present invention is in operation, the water quality monitoring module 200 monitors the water temperature and water quality index of the target water area in real time. Once the water temperature or water quality index exceeds the preset threshold, the controller unit 201 will send a corresponding control signal. According to the delivery signal, the intelligent delivery module 300 will deliver microbial strains (corresponding microbial strains can be delivered according to the different water quality indexes exceeding the preset value) to improve the water quality; according to the first control signal, the drive component will start the heat dissipation function to move adjacent floating island units away from each other for heat dissipation, and according to the second control signal, the floating island unit 2 will be restored to reset after the water temperature returns to normal.

[0035] Further preferably, the intelligent delivery module 300 includes a medicine barrel 301 arranged on the upper end surface of the cross 4, a counterweight block 302 arranged on the lower end surface of the cross 4, and an electrically controlled delivery barrel 303 arranged at the lower end of the counterweight block 302 and connected to the medicine barrel 301 (connected to the medicine barrel, used for electrically controlling the discharge of microorganisms in response to a delivery signal), a horizontal mounting surface and a delivery port 3 opened on the outer periphery of the horizontal mounting surface are provided at the lower end of the electrically controlled delivery barrel 303, the electrically controlled delivery barrel 303 is connected to the controller unit 201 by signal, and the water quality monitoring module 200 is arranged on the horizontal mounting surface.

[0036] The intelligent delivery module 300 in the present invention is respectively arranged at the four ends and the center of the cross 4, including a medicine barrel 301, a counterweight block 302 (the counterweight block effectively prevents the floating island from shaking or deflecting due to external factors such as wind, waves, and water flow by increasing the downward pressure of the floating island in the water) and an electric control delivery barrel 303. The lower end of the electric control delivery barrel is provided with a horizontal mounting surface and a delivery port 3 opened on the periphery of the horizontal mounting surface, which is connected to the controller unit 201 by signal. When the water quality monitoring module 200 sends a delivery signal, the electric control delivery barrel 303 responds to the signal and delivers microbial strains to the target water area to improve the water quality. The delivered microbial strains can decompose organic matter in the water, reduce nitrogen and phosphorus content, and improve water transparency.

[0037] like Figure 7 As shown, further preferably, the driving assembly includes a first chamber 9 opened in the floating island unit 2, and a slide member 12 slidably connected to the inner wall of the first chamber 9, the slide member 12 and the inner wall of the first chamber 9 are provided with an elastic member 14 for resetting the slide member 12, the end of the slide member 12 extending outside the first chamber 9 is connected to a positioning plate 7, and the positioning plate 7 is fixedly connected to the side of the cross 4 (fixed by a limiting hole 19 on the cross 4); a gas generator 15 connected to the signal of the controller unit 201 is provided in the first chamber 9. The driving assembly also includes a second chamber 10 and a third chamber 11, and a piston plate 17 slidably connected to the inner wall of the second chamber 10. A connecting rod 13 is provided on one end face of the piston plate 17 and extends to the outside of the second chamber 10 and is connected to the positioning plate 7. The first chamber 9 and the second chamber 10 are connected through an electromagnetic one-way valve 16, and the second chamber 10 and the third chamber 11 are connected through a one-way valve 18. The electromagnetic one-way valve 16 is connected to the controller unit 201 signal, and is used to respond to the second control signal to allow the gas in the first chamber 9 to enter the second chamber 10; each floating island unit 2 includes a third chamber 11, and the planting tube 6 is provided with an exhaust hole 8 connected to the third chamber 11. The connection between the positioning plate 7 and the slide member 12 and the connecting rod 13 has a sliding spacing perpendicular to the slide member 12 or the connecting rod 13.

[0038] In order to deal with the heat dissipation problem of the ecological floating island caused by excessive water temperature, the present invention also designs a drive assembly. When the controller unit 201 sends a first control signal (water temperature is too high), the gas generator 15 works, generates gas to enter the first chamber 9, pushes the slide plate 12 to slide, and then drives the positioning plate 7 and the floating island unit 2 to move, so that the adjacent floating island units 2 are away from each other for heat dissipation. In addition, the drive assembly also includes a second chamber 10 and a third chamber 11, and a piston plate 17 slidably connected to the inner wall of the second chamber 10. When the controller unit 201 sends out the second control signal (the water temperature returns to normal at this time), the first chamber 9 needs to be exhausted. At this time, the electromagnetic one-way valve 16 is opened by the second control signal, and the gas in the first chamber 9 enters the second chamber 10. At this time, due to the restoring force of the elastic member 14, the slide member 12 drives the floating island unit 2 to reset. During this process, the second chamber 10 stores gas from the first chamber 9, and the gas of multiple second chambers 10 can enter the third chamber 11 through the one-way valve 18 (without the need for electrical signal control). Even if the air pressure in the second chamber 10 is the same as the air pressure in the third chamber 11, when the next sliding of the slide member 12 is performed in the first chamber 9, the piston plate 17 will be driven to slide along the inner wall of the second chamber 10 through the connecting rod 13, so that the internal gas is transferred to the third chamber 11 through the one-way valve 18, and the gas in the third chamber 11 is discharged through the exhaust hole 8.

[0039] It should be further explained that the principle of heat dissipation by separating the floating island units in the present invention is that the spacing between the floating islands can improve the air circulation and water flow above the floating islands. Air circulation helps to reduce the temperature of the floating island surface and reduce plant stress caused by high temperature. At the same time, air circulation also helps to remove volatile substances in the water around the floating islands, such as greenhouse gases such as methane, to reduce the greenhouse effect. The water flow can distribute the heat in the water around the floating islands more evenly, thereby reducing local overheating. In addition, the present application actually monitors the temperature difference between the end and the center of the cross (4), or the end temperature, or the center temperature. The end temperature actually includes the water temperature when the sun is directly shining. When the first control signal is issued, it indicates that the temperature difference between the inside and the outside is too large (the threshold value must be set larger than the cooling range that the floating island itself can achieve. For example, the existing floating island can cool down by 1-3°C. If the monitored difference is 5°C, the heat dissipation will be started separately), or the end temperature is abnormal (the floating island is separated to allow the water to flow to dissipate the heat to the edge of the floating island, so as to achieve uniform heating inside and outside the floating island), or the center temperature is abnormal (the floating island is separated to allow air flow and water flow to equalize the heat).

[0040] In the ecological floating island design of the present invention, when the gas in the third chamber 11 is discharged through the exhaust hole 8, the gas can be effectively used to clean the roots of the plants in the planting tube 6 and prevent the impurities and microorganisms from gathering at the bottom of the floating island unit 2 in the aquatic environment; specifically, root cleaning: the gas discharged from the exhaust hole 8 can generate a certain airflow, which can blow the roots of the plants in the planting tube 6 to help remove impurities attached to the roots, such as mud, suspended matter, etc. The oxygen and other components that may be contained in the gas help promote the respiration of the roots and improve the vitality of the root system. Prevent the aggregation of impurities and microorganisms: The disturbance generated when the gas is discharged can prevent the impurities and microorganisms at the bottom of the floating island unit 2 from being stationary for a long time and gathering together, thereby reducing the risk of negative impacts on water quality and the ecosystem. Through regular gas discharge, the fluidity and activity of the water body around the floating island can be maintained, which helps to maintain the balance of the ecosystem.
