Description

Technical Field

[0001] The invention relates to the technical field of marine ecological protection, and in particular to an array-type artificial upwelling sink enhancement device. Background Art

[0002] Global warming has become an imminent global problem. Emission reduction and carbon sink enhancement are the inevitable ways to achieve the reduction of carbon dioxide (CO2) in the atmosphere. At present, countries around the world have come up with endless means to reduce emissions, but the attention to carbon sink enhancement is slightly insufficient. The ocean is the largest active carbon reservoir on the earth. As the largest carbon sink, it can absorb about 30% of the CO2 released by humans every year. The huge carbon absorption capacity of the ocean plays an important role in reducing CO2 in the atmosphere and mitigating global warming. Marine carbon sinks are mainly the process, activities and mechanisms of absorbing and storing CO2 in the atmosphere from the air or seawater using mangroves, salt marshes, seagrass beds, phytoplankton, large algae, shellfish, etc.

[0003] Shellfish and algae are important marine primary producers in shallow waters, and large algae and shellfish in the continental shelf area account for about 35% of the global ocean's annual net carbon fixation, and are an important part of the marine carbon sink. Studies have shown that shellfish and algae farming is one of the effective technical approaches to achieve biological carbon sink expansion, with great operability and potential. Therefore, in recent years, the scale of shellfish and algae farming in my country's near-shore environment has become increasingly larger, which is of great significance to the restoration of the entire marine ecological environment.

[0004] Water temperature, dissolved oxygen, and nutrient salt components are important factors for the growth of shellfish and algae. Suitable temperature promotes the growth of shellfish and algae, while too low temperature inhibits it. Because shellfish and algae grow below the surface sea level, as the water depth increases, the temperature and dissolved oxygen content will become lower and lower. At the same time, due to the increase in water temperature, the dissolved oxygen content in the growth environment of shellfish and algae below the surface seawater will be greatly reduced, which will further inhibit the growth of algae. Moreover, shellfish and algae need to consume a large amount of nutrients (especially nutrients) during their growth, especially in summer when the algae grows faster, so they will consume a large amount of nutrients, resulting in a decrease in the nutrient content in the area. Algae is also one of the important food sources for marine plankton. There is a large amount of organic matter in the growth environment of algae. Therefore, there are multiple groups of organisms living at the same time in the algae breeding area, which further leads to a lack of nutrients in the area, affecting the normal growth of algae, and thus has a significant impact on the absorption capacity of atmospheric carbon dioxide. How to use artificial intervention to improve the environment of algae farming areas to promote the growth of shellfish algae and increase the carbon sequestration of shellfish algae has become one of the urgent problems to be solved.

[0005] In recent years, the emergence of artificial upwelling technology has made it possible to blend deep seawater with surface seawater, thereby optimizing the temperature, nutrient content, etc. of the surface seawater. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0025] The present embodiment provides an array-type artificial upwelling sink device, comprising a floating platform 13, a seawater mixing storage tank 1, a surface seawater storage tank 2, a bottom seawater storage tank 3 and an extraction mechanism; the seawater mixing storage tank 1 is connected to the floating platform 13 through a support, and a conveying mechanism is connected thereto; the surface seawater storage tank 2 is arranged on one side of the seawater mixing storage tank 1 and is connected to the floating platform 13 through a support, and the surface seawater storage tank 2 is communicated with the seawater mixing storage tank 1 through a first water inlet pipe 7; the bottom seawater storage tank 3 is distributed on the floating platform 13 in a triangular shape with equal intervals between the seawater mixing storage tank 1 and the surface seawater storage tank 2, and is communicated with the seawater mixing storage tank 1 through a second water inlet pipe 71; the extraction mechanisms are respectively arranged on the surface seawater storage tank 2 and the bottom seawater storage tank 3, and are suitable for simultaneously and separately pumping seawater of different depths into corresponding storage tanks.

[0026] Furthermore, the floating platform 13 is an equilateral triangle structure, and the seawater mixing storage tank 1, the surface seawater storage tank 2 and the bottom seawater storage tank 3 are respectively distributed at three angles of the floating platform 13 at equal intervals around the central axis of the floating platform 13.

[0027] In the above embodiment, the floating platform 13 floats on the sea in the aquaculture area. The floating platform 13 is arranged in a triangular shape. Three cabins are evenly spaced on the triangular angle of the floating platform 13, wherein the surface seawater storage cabin 2 and the bottom seawater storage cabin 3 are respectively connected to the seawater mixing storage cabin 1. The surface seawater storage cabin 2 and the bottom seawater storage cabin 3 are respectively used to store seawater extracted from the surface and the bottom. The extracted seawater is fine-tuned for the physical and chemical parameters that exceed the range in the corresponding cabins. For example, when the temperature of the bottom seawater is too low, it needs to be slightly adjusted upward to avoid the temperature and dissolved oxygen content of the surface seawater being lower than the range suitable for the growth of shellfish and algae after the surface seawater is mixed with the bottom seawater. Similarly, when the nutrient concentration of the surface seawater is too low, its value needs to be fine-tuned upward to avoid the nutrient concentration of the bottom seawater being too low after the bottom seawater is mixed with the surface seawater.

[0028] In the above embodiment, the surface seawater and the bottom seawater are extracted from the original aquaculture area at the same time, and then respectively input into the surface seawater storage tank 2 and the bottom seawater storage tank 3 to adjust the corresponding parameters, and then the surface seawater and the bottom seawater are simultaneously transported to the seawater mixing storage tank 1 for mixing, and the mixed seawater is then transported to the marine environment that needs to be improved through the transport mechanism. The neutralized seawater will have the high content of dissolved oxygen and high water temperature of the surface seawater and the high nutrient salt of the bottom seawater, which can effectively regulate the nutrient salt, temperature, dissolved oxygen and other physical and chemical parameters of the aquaculture area, effectively alleviate the problems of low oxygen, low temperature and oligonutrients in the aquaculture area, create a marine environment suitable for the growth of shellfish and algae, increase the aquaculture yield of shellfish and algae, promote marine carbon sinks, and have great significance for the restoration of the entire marine ecological environment.

[0029] In an optional embodiment, the extraction mechanism includes a water pump 15, a first delivery pipe 4 and a second delivery pipe. The water pump 15 is arranged at the top of the storage tank. One end of the water pump 15 is connected to the first delivery pipe 4, and the other end is connected to the second delivery pipe. The first delivery pipe 4 is vertically penetrated at the bottom of the storage tank and extends to the bottom of the floating platform 13 by a preset length. The second delivery pipe is vertically penetrated at the upper end of the storage tank and extends to the lower part of the storage tank by a preset length. The length of the first delivery pipe 4 for extracting seawater from different positions is different. The length of the first delivery pipe 4 for extracting surface seawater is shorter, while the length of the first delivery pipe 4 for extracting bottom seawater is longer. The seawater is extracted into each cabin by the water pump 15. A seal is arranged at the connection between the first delivery pipe 4 and the cabin body to prevent the seawater from flowing in from here and the seawater in the cabin body from flowing out of the cabin body. The water pump 15 is arranged on the top end surface of the cabin body. After the seawater is transported up through the first delivery pipe 4, it flows into the cabin body from above through the second delivery pipe.

[0030] In an optional embodiment, the extraction mechanism of the bottom seawater storage tank 3 also includes a gas delivery component, which includes a riser and a gas injection structure; the riser is vertically connected to the bottom end of the floating platform 13 and wraps the first delivery pipe 4 therein, and there is a set distance between the inner wall of the riser and the outer wall of the first delivery pipe 4; the gas injection structure includes an air compressor 18 and a jet head 21, and the jet head is placed inside the riser, and the jet head 21 includes an annular jet pipe and a jet cylinder located at the central axis of the jet pipe, and the outer wall of the jet cylinder is connected to the inner wall of the jet pipe through three connecting pipes, and the three connecting pipes are circumferentially evenly spaced, and the top end of the jet cylinder is connected to the air compressor 18 through the gas pipe 19, and a plurality of jet columns 22 are evenly connected on the top end faces of the jet pipe, the jet cylinder and the connecting pipe.

[0031] In a further preferred embodiment, the riser pipe includes an upper riser pipe 8 and a lower riser pipe 81. The upper riser pipe 8 is fixedly connected to the lower end of the floating platform 13. The outer diameter of the lower riser pipe 81 is larger than the outer diameter of the upper riser pipe 8 and is coaxially arranged with the upper riser pipe 8. The lower riser pipe 81 is separated from the upper riser pipe 8 and can slide up and down relative to the upper riser pipe 8 through an external sliding component.

[0032] In the above embodiment, since the seawater at the bottom is difficult to be pumped up by a water pump alone, it is necessary to use gas to make the water body surge upward. The seawater in the riser can be lifted up by the action of the gas injection nozzle, which is convenient for the water pump of the bottom seawater storage tank 2 to pump up the seawater in the deep layer. By designing the riser to be divided into two parts, the distance between the two riser pipes can be adjusted when the lower riser pipe 81 is moved up and down, and the height of the lower riser pipe 81 can be adjusted, so that the opening of the lower riser pipe 81 is located at different depths. Therefore, through the action of the jet nozzle 21, the seawater at the bottom can be located at different depths when it surges out from the opening of the lower riser, so that it can adapt to the shellfish and algae at different depths and provide comprehensive nutrient salt supplementation for the algae and shellfish at different depths.

[0033] In an optional embodiment, the external sliding assembly includes a first threaded rod 9 and a first slide rod 91 vertically arranged on the outside of the upper section riser 8, the top end of the first threaded rod 9 extends into the floating platform 13 and is connected to the first drive motor, and the bottom end thereof extends downward by a preset distance, the outer wall of the lower section riser 81 is sleeved on the first threaded rod 9 through a first movable block 92 and is threadedly connected to the first threaded rod 9, the upper end of the first slide rod 91 is fixedly connected to the outer wall of the upper section riser 8, and the lower end extends downward by a preset length, the outer wall of the lower section riser 81 is connected to a first sliding sleeve 10 at the position corresponding to the first slide rod 91, and the lower section riser 81 is sleeved on the first slide rod 91 through the first sliding sleeve 10 and is slidably connected to the first slide rod 91.

[0034] In other embodiments, riser pipes are provided on the outside of the first delivery pipe 4 of the surface seawater storage compartment 2 and on the outside of the output pipe 5 of the seawater mixing storage compartment 1. The structure, function and driving method of the riser pipes are consistent with those of the bottom seawater storage compartment 3. The structure is not repeated here. By setting three riser pipes at the same time, the seawater in the bottom layer can be pumped up at the same time. The openings of the three lower riser pipes can be arranged in a stepped manner, respectively at the upper, middle and lower positions. When the bottom water is pumped up at the same time, a large-scale artificial upwelling can be formed, thereby comprehensively increasing the nutrient content of the aquaculture area, while enhancing the water flow in the area and increasing the nutrient content in the area.

[0035] In an optional embodiment, there are two nozzles 21, and the two nozzles 21 are vertically spaced from top to bottom inside the lower riser 81, and the two nozzles 21 can move up and down relative to the lower riser 81 through an internal sliding assembly, and the internal sliding assembly includes a second threaded rod, a second slide rod, a third threaded rod and a third slide rod, the top ends of the second threaded rod and the third threaded rod respectively extend upward into the floating platform 13 and are connected to the second drive motor and the third drive motor, and their bottom ends extend downward by a preset distance; the outer wall of the upper nozzle 21 is sleeved on the second threaded rod through a second movable block and is threadedly connected to the second threaded rod, the upper end of the second slide rod is fixedly connected to the inner wall of the upper riser 8, and the lower The end passes through the lower section of the riser pipe 81 and extends downwardly for a preset length. The outer wall of the upper jet head 21 is connected to a second sleeve at a position corresponding to the second slide rod. The upper jet head is sleeved on the second slide rod through the second sleeve and is slidably connected to the second slide rod; the outer wall of the lower jet head 21 is sleeved on the third threaded rod through a third movable block and is threadedly connected to the third threaded rod. The upper end of the third slide rod is fixedly connected to the inner wall of the upper section of the riser pipe 8, and the lower end passes through the lower section of the riser pipe 81 and extends downwardly for a preset length. The outer wall of the lower jet head 21 is connected to a third sleeve at a position corresponding to the third slide rod. The lower jet head 21 is sleeved on the third slide rod through the third sleeve and is slidably connected to the third slide rod.

[0036] In the above embodiment, the upper end of the upper riser 8 is fastened to the lower end of the floating platform 13 by bolts. The upper riser 8 has a certain length. A first drive motor, a second drive motor and a third drive motor are arranged on the floating platform 13. The first drive motor is located on the outer side of the upper riser 8, and the second drive motor and the third drive motor are located on the inner side of the upper riser 8. The first drive motor, the second drive motor and the third drive motor all use waterproof motors, and the first threaded rod 9, the second threaded rod and the third threaded rod are vertically connected to the output shaft at the bottom thereof. The first motor, the second motor and the third motor are all electrically connected to the control system, and can automatically move the lower riser up or down according to the set parameters, and can automatically adjust the height of the upper jet head 21 and the lower jet head 21 according to the set parameters. In addition to playing a certain guiding role, the sliding rod can also improve the stability during movement and is not prone to shaking.

[0037] In the above-mentioned embodiment, gas is injected into the nozzle through the air compressor 18 and the gas is sprayed upward through the nozzle 21, which can effectively form a large-scale, high-efficiency pneumatic lift-type artificial upwelling in the offshore aquaculture environment. The depth of the lower riser 81 and the arrangement of the nozzle 21 can be adaptively controlled, so as to achieve intelligent control of the plume flow and range, and specifically enhance the local water flow, which is complementary to the control of the in-situ physical and chemical parameters of the seawater by extracting the surface seawater and the bottom seawater for mixing, further improving the seawater environment of the aquaculture environment, promoting the growth of shellfish and algae, and increasing marine carbon sinks.

[0038] In an optional embodiment, the conveying mechanism includes a water pump 15 and an output pipe 5, wherein the output pipe 5 is vertically penetrated through the seawater mixing storage tank 1, and the end thereof extends downward by a preset length. The output pipe 5 is provided with a plurality of water outlets distributed from top to bottom, and is suitable for conveying the conditioned seawater in the seawater mixing storage tank 1 to aquaculture areas of different depths to adapt to the growth of shellfish and algae at different depths.

[0039] In this embodiment, the seawater mixing and storage tank 1 is used to mix the water transported from the surface seawater storage tank 2 and the bottom seawater storage tank 3, and respectively utilizes the high dissolved oxygen and high temperature of the surface seawater and the high nutrient salts of the bottom seawater, so that the mixed seawater has the advantages of both surface seawater and bottom seawater. The regulated seawater is then transported to the shellfish and algae breeding area to improve the low temperature, low dissolved oxygen and oligonutrient conditions in the area. By opening a plurality of outlets at different heights from top to bottom on the output pipe 5, the regulated seawater can flow into the breeding areas of different depths, and the regulated seawater can be comprehensively transported to the shellfish and algae breeding environments of different water depths, covering a wide range.

[0040] In an optional embodiment, it also includes a wave energy collection unit and a solar energy collection unit, the wave energy collection unit includes a buoy and a hydraulic telescopic rod 11, the buoy 6 is arranged above the floating platform 13 and forms a set distance with the upper end of the floating platform 13, the buoy 6 is hinged with the outer walls of the seawater mixing storage cabin 1, the surface seawater storage cabin 2, and the bottom seawater storage cabin 3 respectively by the hydraulic telescopic rod 11; a triangular truss structure is connected between the seawater mixing storage cabin 1, the surface seawater storage cabin 2, and the bottom seawater storage cabin 3, the bottom end of the triangular truss structure has a set distance from the top of the floating platform, a through opening is opened on the end surface of the floating platform 13, the lower part of the buoy 6 is penetrated on the bottom end of the truss structure and extends downward into the through opening; the solar energy collection unit is arranged on the top of the buoy 6, the seawater mixing storage cabin 1, the surface seawater storage cabin 2, and the bottom seawater storage cabin 3, and the solar energy collection unit and the wave energy collection unit are connected to the energy storage unit through a cable.

[0041] In the above embodiment, under the vertical action of waves, the port will cause the buoy 6 to make vertical relative movement with respect to the storage compartment, driving the hydraulic telescopic rod 11 to reciprocate and retract, and the mechanical energy absorbed by the reciprocating motion is converted into hydraulic energy, and the hydraulic energy is converted into kinetic energy through the rotation of the hydraulic motor. The generator rotates and generates electricity under the drive of the hydraulic motor, and the electricity generated by the generator will be stored in the storage unit. The solar energy collection unit captures light energy through solar panels, converts it through inverters, etc., and then stores electricity in the battery 17 of the energy storage unit, which complements the wave energy and provides continuous and stable energy for the device.

[0042] In an optional embodiment, it also includes a liquid distribution mechanism, which is respectively arranged on the seawater mixing storage tank 1, the surface seawater storage tank 2, and the bottom seawater storage tank 3. The liquid distribution mechanism includes a liquid distribution tank 14, and an electronic control valve is connected to the liquid outlet of the liquid distribution tank 14, and the electronic control valve is electrically connected to the control system 16.

[0043] In the above embodiment, after the surface seawater and the bottom seawater are simultaneously extracted, when some physical and chemical parameters are too high or too low, in order to avoid the influence of mixing the two, the parameters can be fine-tuned in the corresponding cabins respectively. For example, when the temperature of the bottom seawater is too low, in order to prevent the overall water temperature from being lower than the original surface water temperature or lower than the temperature of the aquaculture area that needs to be improved after mixing with the surface water, the bottom water temperature needs to be raised first. Similarly, when the dissolved oxygen of the bottom seawater and the nutrient salt concentration of the surface seawater are too low, they also need to be fine-tuned. The physical and chemical parameter data of the extracted seawater are transmitted to the processor through the action of the sensor. After analysis, the processor determines which physical and chemical parameters of the seawater are higher or lower, and then the liquid distribution tank 14 is used for corresponding replenishment and improvement, so that the physical and chemical parameters of the surface seawater and the bottom seawater are within a more appropriate range, and a certain parameter is not too high or too low, so that after the two are mixed, their respective advantages can be maximized and other parameters are within a reasonable range.

[0044] It should be noted that, in actual application, the present invention involves the extraction of surface seawater and deep seawater, the adjustment of the physical and chemical parameters of seawater, and the transportation of the adjusted seawater to a seawater mixing storage tank. When the surface water and bottom water are mixed and the final parameter index values ​​are outside a reasonable range, they need to be adjusted again until all parameter values ​​are within a reasonable range before they can be discharged to the desired sea area.
