Their core function is to provide a constant-temperature, sterile environment, simulating the natural growth conditions of microorganisms by precisely controlling parameters such as temperature, humidity, and light, thereby promoting their efficient reproduction. This equipment is widely used in food processing, pharmaceutical production, environmental engineering, aquaculture, and biotechnology. Currently, existing algae and microbial culture tanks suffer from the disadvantage of relying on manual observation and sampling for monitoring the cultivation status. Utility Model Content

[0033] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 to 2 This utility model provides an automatic detection device for a bacterial and algal cultivation tank 1, including a cultivation tank 1, a first electric push rod 2, a second electric push rod 8, a fixed crossbar 3, a vertical rod 4, a detection module 5, and a membrane breaking sleeve 6.

[0035] The first electric push rod 2 is disposed on one side of the culture tank 1;

[0036] One end of the fixed crossbar 3 is connected to the piston rod of the first electric push rod 2, and the other end of the fixed crossbar 3 is connected to the upright rod 4;

[0037] One end of the bottom of the upright 4 is connected to the detection module 5;

[0038] The membrane-breaking sleeve 6 is sleeved on the upright 4, and a number of sharp protrusions are arranged at one bottom end of the membrane-breaking sleeve 6;

[0039] The second electric push rod 8 is mounted on the fixed crossbar 3, and the second electric push rod 8 is connected to the membrane breaking sleeve 6 through a piston rod;

[0040] During use, bacterial and algal cells or secretions (such as polysaccharides and proteins) may accumulate on the liquid surface, forming a biofilm. If the detection module 5 is directly inserted into the cultivation tank 1, the biofilm will cover the sensor probe (such as pH electrode and dissolved oxygen sensor), hindering direct contact with the liquid and causing data lag or deviation. Furthermore, since multispectral imaging or turbidity detection relies on light signals penetrating the liquid, the scattering or absorption of the membrane will reduce the signal-to-noise ratio and affect the accuracy of chlorophyll fluorescence or turbidity measurement. During use, substances inside the membrane may adhere to the sensor surface, causing permanent pollution or corrosion.

[0041] When this application is used, the second electric push rod 8 drives the membrane-breaking sleeve 6 to move downwards, and the sharp protrusion at the bottom of the membrane-breaking sleeve 6 punctures the biofilm in the area to be detected by the detection module 5. Then, the first electric push rod 2 drives the upright rod 4 to move downwards, and the detection module 5 at the bottom of the upright rod 4 automatically detects the culture tank 1, which effectively avoids the influence of the biofilm on the detection module 5 and improves the detection accuracy.

[0042] In this embodiment, a cleaning sponge 7 is provided on the inner wall of the membrane breaking sleeve 6. During the process of the second electric push rod 8 driving the membrane breaking sleeve 6 to move, the cleaning sponge 7 is used to clean any impurities that may be attached to the surface of the detection module 5.

[0043] In this embodiment, the detection module 5 includes two sets of sensor modules. One set of sensor modules integrates a temperature sensor, a pH sensor, a dissolved oxygen sensor, and a light sensor. The other set of sensor modules is a high-precision optical sensor that uses a multispectral imaging probe and integrates a chlorophyll fluorescence detection module and a turbidity detection module.

[0044] The sensor module of this application only enters the tank or below the liquid surface when working, thus extending the sensor's lifespan. Furthermore, the multi-source sensor of this application can be combined with fuzzy PID control to achieve intelligent control of the algae cultivation device. Compared with traditional manual detection methods, the detection efficiency is increased by more than 50%, and the single detection cycle is shortened to 3 minutes. This provides an intelligent control solution for algae cultivation that is timed, efficient, labor-saving, and has a longer sensor lifespan.

[0045] In this embodiment, a heating pipe 9 is installed inside the culture tank 1. The heating pipe 9 is located inside the culture tank 1 and has a hot water inlet and a hot water outlet at the part extending out of the culture tank 1.

[0046] In this embodiment, the membrane-breaking sleeve 6 is internally threaded with an inner tube body, and a cleaning sponge 7 is provided inside the inner tube body. By providing the inner tube body, the cleaning sponge 7 inside the membrane-breaking sleeve 6 can be quickly replaced.

[0047] In this embodiment, the cultivation tank 1 is equipped with a stirring mechanism 10. The stirring mechanism 10 is used to stir the inside of the cultivation tank 1, and to fully stir the bacteria and algae, so that the bacteria and algae are mixed more evenly and avoid settling to the bottom. At the same time, it also further ensures that the bacteria and algae can be fully and evenly irradiated with suitable light.

[0048] The working principle of this utility model is as follows:

[0049] The second electric push rod 8 drives the membrane-breaking sleeve 6 to move downwards, using the sharp protrusion at the bottom of the membrane-breaking sleeve 6 to puncture the biofilm in the area to be detected by the detection module 5. Then, the first electric push rod 2 drives the upright rod 4 to move downwards, and the detection module 5 at the bottom of the upright rod 4 automatically detects the culture tank 1, effectively avoiding the influence of the biofilm on the detection module 5 and improving the detection accuracy.

[0050] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
