Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-4 A device for improving the carbon fixation efficiency of aquatic plants includes a culture box 1, which is filled with water to cultivate aquatic plants. A lid 2 is installed on the top of the culture box 1, and an adjustable light intensity lighting mechanism is installed on the lower surface of the lid 2 to provide suitable light for the aquatic plants. An aeration mechanism 4 is installed at the bottom of the culture box 1, which is connected to a carbon dioxide storage tank 6 outside the culture box 1 via a delivery pipe 5. The carbon dioxide storage tank 6 is fixed to the outer wall of the culture box 1. A first metering pump 7 is connected to the portion of the delivery pipe 5 outside the culture box 1, which can meterly pump carbon dioxide into the culture box 1, thereby promoting photosynthesis in the aquatic plants. A circulating water pipe 9 is connected between the upper and lower parts of the side wall of the incubator 1. A circulating water pump 10 is connected to the circulating water pipe 9. Both the inlet and outlet ends of the circulating water pipe 9 penetrate the side wall of the incubator 1 and extend into the interior of the incubator 1. The circulating water pump 10 and the circulating water pipe 9 are used to achieve continuous circulation of water in the incubator 1. A nutrient solution storage tank 11 is provided on the top of the lid 2. A nutrient solution delivery pipe 12 is connected to the nutrient solution storage tank 11. The other end of the nutrient solution delivery pipe 12 penetrates the lid 2 and extends into the incubator 1. A second metering pump 13 is connected to the nutrient solution delivery pipe 12. The second metering pump 13 can pump the nutrient solution in the nutrient solution storage tank 11 into the incubator 1 in a metered manner.

[0021] In this embodiment, the nutrient solution in the nutrient solution storage tank 11 is a nutrient solution containing elements such as nitrogen and phosphorus required for the growth of aquatic plants.

[0022] In this embodiment, the aeration mechanism 4 includes an aeration main pipe 41, one end of which is connected to the delivery pipeline 5. Several aeration branch pipes 42 are connected to both sides of the aeration main pipe 41, and several microporous aeration discs 43 are installed at the top of each aeration branch pipe 42. The arrangement of the aeration branch pipes 42 and the microporous aeration discs 43 enables the uniform distribution of carbon dioxide into the water, thereby facilitating the absorption and utilization by aquatic plants.

[0023] In this embodiment, the inlet end of the circulating water pipe 9 is located at the upper part of the incubator 1, and the outlet end of the circulating water pipe 9 is located at the lower part of the incubator 1.

[0024] In this embodiment, a filter screen 14 is installed at the inlet end of the circulating water pipe 9, which can filter out impurities and prevent impurities from entering the circulating water pipe 9 and the circulating water pump 10 and causing blockage.

[0025] In this embodiment, a water distribution mechanism 8 is installed at the outlet end of the circulating water pipe 9. The water distribution mechanism 8 includes a main water distribution pipe 81, which is installed on the bottom wall of the incubator 1 via a bracket 15 and located above the aeration mechanism 4. Several water distribution branch pipes 82 are connected to both sides of the main water distribution pipe 81, and several water distribution holes 821 are opened at the top of each water distribution branch pipe 82. The water distribution mechanism 8 enables the water discharged from the outlet end of the circulating water pipe 9 to be evenly distributed in the incubator 1, making the water circulation in the incubator 1 more thorough. At the same time, it also enables carbon dioxide and nutrient solution to be evenly distributed in the water, thereby promoting the absorption and utilization of aquatic plants and thus improving the carbon fixation efficiency of aquatic plants.

[0026] In this embodiment, a temperature sensor 16 is installed inside the incubator 1. The temperature sensor 16 is fixedly connected to the bottom of the cover 2 via a fixing rope 17. The temperature sensor 16 can monitor the temperature of the water in the incubator 1 in real time.

[0027] In this embodiment, a heating sleeve 18 is fitted on the circulating water pipe 9. The heating sleeve 18 includes an outer protective sleeve 181 and a spiral heating wire 182 embedded inside the outer protective sleeve 181, which is used to heat the circulating water pipe 9. When the water temperature in the incubator 1 is too low, the heating sleeve 18 can be turned on to heat the circulating water pipe 9, thereby gradually raising the water temperature to a suitable value during the water circulation process to ensure the normal growth of aquatic plants.

[0028] In this embodiment, the lighting mechanism is an LED lamp 3 with adjustable light intensity, which can provide appropriate light for aquatic plants, thereby promoting photosynthesis and improving the carbon sequestration efficiency of aquatic plants.

[0029] In this embodiment, a PLC controller is also included. The first metering pump 7, the second metering pump 13, the illumination mechanism, the temperature sensor 16, and the heating jacket 18 are all electrically connected to the PLC controller, thereby realizing automated and intelligent control of nutrient solution addition, circulating water flow, light intensity, carbon dioxide supply, and water temperature.

[0030] The working principle of this utility model is as follows:

[0031] When using this device, aquatic plants are first planted on a suitable substrate in the cultivation tank. Based on the species and growth stage of the aquatic plants, the light intensity is adjusted to an appropriate range using the lighting mechanism. Then, the first metering pump 7 is turned on, slowly releasing carbon dioxide into the water through the microporous aeration disc 43 at a set flow rate, maintaining the carbon dioxide concentration in the water at a level conducive to carbon fixation by the aquatic plants. Simultaneously, the circulating water pump 10 is turned on to circulate the water, ensuring that the aquatic plants are evenly exposed to carbon dioxide and nutrients. By controlling the second metering pump 13 to replenish nutrients in the cultivation tank at predetermined time intervals and dosages, the vigorous growth of the aquatic plants is maintained, thereby improving their carbon fixation efficiency.

[0032] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
