[0002] In recent years, the ecosystems of lakes, rivers and other aquatic bodies have been damaged, with increased suspended solids and decreased transparency, affecting the ecological function and landscape effect of the water bodies. Restoring aquatic plants is an important measure for the ecological restoration of damaged water bodies. Therefore, research on aquatic plants has attracted the attention of researchers.

[0003] Existing devices for measuring the photosynthetic intensity of aquatic plants are inconvenient for fixing and adjusting the position of the plants to be tested, which can easily lead to plant movement and damage during the experiment, affecting the rigor of the experimental results. It is also inconvenient to replace the aquatic plants being tested during the experiment, which slows down the experimental speed and reduces the efficiency of the experiment. Furthermore, the inability to adjust the light source intensity makes it impossible to simulate the light transmittance of different water depths and turbid water bodies, causing the experimental results to deviate from reality and resulting in unreliable experimental results.

[0004] The inconvenience of fixing and adjusting the position of the plants required for the experiment can easily lead to plant movement during the experiment, causing damage to the plants and affecting the accuracy of the experimental results; the inconvenience of replacing the aquatic plants being tested slows down the experimental speed and reduces experimental efficiency; and the inability to adjust the intensity of the light source makes it impossible to simulate the lighting conditions in the real environment, causing the experimental results to deviate from reality and resulting in unreliable experimental results. Summary of the Invention

[0023] A clamping unit 2 is provided, comprising a threaded rod 24, a lifting plate 25, a top rod 251, and a planting clip 252. The threaded rod 24 is threadedly connected to the lifting plate 25, enabling the lifting plate 25 to move up and down. The top rod 251 is located on top of the lifting plate 25; when the lifting plate 25 rises, the top rod 251 abuts against the sealing cover 3, causing the sealing cover 3 to move upward and open the device, facilitating the replacement of experimental plants.

An air inlet pipe 412 and an air outlet pipe 413 are fixedly installed on the outside of the container wall 41. The air inlet pipe 412 and the air outlet pipe 413 are symmetrically arranged on both sides of the container wall 41. An arc groove is opened at the top of the container wall 41. The sealing ring 42 is snapped into the inner side of the arc groove. A locking platform is provided at the top of the container wall 41.

[0029] It should be emphasized that the container 4 also includes a stirring pump 44 and a circulation pump 45. The stirring pump 44 is located on the outside of the container wall 41, and the output end of the stirring pump 44 is inserted into the container wall 41. The output end of the stirring pump 44 passes through the container wall 41 to the inside of the container wall 41. An impeller 441 is sleeved on the outside of the output end of the stirring pump 44. The impeller 441 is driven by the stirring pump 44 to stir the water in the container 4.

[0030] It is particularly important to emphasize that the circulation pump 45 is located on the outside of the barrel wall 41, and the circulation pump 45 is located between the heating aluminum platform 13 and the base plate 14. The circulation pump 45 is connected to the circulation water pipe 451, and both ends of the circulation water pipe 451 are fixedly connected to the barrel wall 41. The circulation water pipe 451 is connected to the inside of the barrel wall 41.

[0033] Working Principle: This device measures plant photosynthesis by analyzing changes in dissolved oxygen concentration in the water using the control panel 432. During the measurement process, the system monitors and records changes in various parameters in real time and transmits the data to a computer for analysis and processing. Analysis of this data allows for the determination of the photosynthetic intensity, respiration intensity, and other relevant physiological indicators of aquatic plants.

[0034] First, the clamping unit 2 is controlled via the control panel 432. The power motor 21 drives the transmission gear 22 to drive the linkage gear 23, which in turn drives the threaded rod 24. The threaded rod 24 passes through the cover plate 31 and is threadedly connected to the lifting plate 25. The threaded rod 24 drives the lifting plate 25 to rise. During the rise of the lifting plate 25, the top rod 251 set on it abuts against the cover plate 31, causing the cover plate 31 to move upward and open the sealing cover 3. Then, sufficient water to meet the experimental requirements is injected into the container 4. Then, the prepared aquatic plants are clamped and fixed by the planting clip 253. After that, the control panel 432 is used to control the threaded rod 24 to drive the lifting plate 25 to descend, so that the aquatic plants to be tested reach the designated position. During the descent, the cover plate 31 stays at the top of the barrel wall 41. Then, the sealing buckle 33 set on the outside of the cover plate 31 is locked to the outside of the barrel wall 41. The cover plate and the sealing ring 42 are tightly abutted, so that the sealing cover 3 achieves the sealing effect. Then, the light source 34 is started through the light source control panel 32 set on the top of the cover plate 31, and the photochromic glass 35 is set so that the light intensity in the container 4 reaches the experimental requirements. Then, the temperature in the container 4 is adjusted through the temperature control panel 431 so that the temperature in the container 4 reaches the experimental requirements. Finally, the initial experimental data in container 4 is recorded through control panel 432, and the experiment begins. During the experiment, stirring pump 44 needs to be turned on to ensure that the liquid in container 4 is uniform and to ensure the accuracy of the data collected by control panel 432. Control panel 432 records and stores the data during the experiment for easy analysis of the results.
