[0002] Spirulina, a microorganism rich in various nutrients, has wide applications in food, health products, and medicine. With the continuous development of the spirulina industry, the demand for its large-scale, high-efficiency cultivation is increasing. Accurately controlling the concentration of spirulina in the culture medium is crucial during cultivation, as it directly affects the harvesting timing, yield, and the quality of the final product.

[0003] Currently, traditional methods for detecting the concentration of spirulina culture medium have many drawbacks. Typically, growers find it difficult to quickly and accurately determine whether the culture medium has reached the optimal harvest concentration, often requiring offline sampling and testing. This method necessitates manually removing a certain amount of culture medium sample from the culture tank or pipes and then sending it to a laboratory for analysis. The entire process is not only cumbersome and time-consuming, but also susceptible to interference from external factors during sampling, transportation, and testing, affecting the accuracy and timeliness of the results.

[0004] Therefore, in order to solve the above problems, there is an urgent need for a device that can quickly and accurately detect the concentration of spirulina culture medium in real time. Utility Model Content

This probe can calculate the concentration in real time by measuring the absorbance of the culture medium at a specific wavelength, effectively enabling accurate judgment of the harvest time and thus improving the yield and quality of spirulina.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical real-time concentration detection probe for spirulina culture medium, comprising a waterproof shell, a protective lens threadedly connected to the left side of the waterproof shell, a mounting ring fixedly connected to the left side of the interior of the waterproof shell, an LED light source assembly fixedly connected to the left side of the mounting ring, a power module fixedly connected to the right side of the mounting ring, a heat spreader plate fitted to the right side of the power module fixedly connected to the interior of the waterproof shell, a plurality of uniformly distributed annular heat dissipation fins fixedly connected to the right side of the heat spreader plate, the outer sides of the heat dissipation fins extending to the exterior of the waterproof shell, a photosensor module assembly fixedly connected to the right side of the interior of the waterproof shell, the photosensor module assembly including a photosensor, a data processing module, and a wireless transmission module, the input end of the photosensor being coaxial with the center of the protective lens for accurately receiving light change signals, a bottom cover threadedly connected to the right side of the waterproof shell, a flange ring fixedly connected to the right side of the surface of the bottom cover, and an installation structure provided on the right side of the bottom cover.

[0007] As a preferred embodiment of this utility model, the mounting structure includes an internally threaded cylinder fixedly connected to the center of the right side of the bottom cover. The internally threaded cylinder is internally threaded with a threaded post. A mounting plate is fixedly connected to the right side of the threaded post. Mounting holes are provided at all four corners of the mounting plate. The inner and outer surfaces of the internally threaded cylinder and the surface of the threaded post are all provided with an anti-rust coating.

[0008] As a preferred embodiment of this utility model, a heat insulation cylinder is provided inside the waterproof housing. The inner surface of the mounting ring is fixedly connected to the left side surface of the heat insulation cylinder, and the right side surface of the heat insulation cylinder is attached to the inner wall of the waterproof housing.

A filter located on the left side of the input end of the photosensitive module group is fixedly connected inside the heat insulation cylinder to allow only light of a specific wavelength to pass through, thereby improving the selectivity of the detection.

[0009] As a preferred embodiment of this utility model, the protective lens includes an internal threaded ring threaded to the left side of the waterproof housing, and a high-definition explosion-proof glass cover is fixedly connected to the left side of the internal threaded ring.

[0010] As a preferred embodiment of this utility model, a sealing strip is fixedly connected to the outer surface of the heat dissipation fins, the surface of the sealing strip is fixedly connected to the inner wall of the waterproof shell, and a plurality of evenly distributed heat dissipation holes are opened on the outer side of the heat dissipation fins.

[0011] As a preferred embodiment of this utility model, sealing rings are fixedly connected to the right side of the internal threaded ring and the left side of the bottom cover, and the inner sides of the two sealing rings are respectively attached to the left and right ends of the waterproof shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0013] 2. This utility model, through the installation plate and the mounting holes at its four corners, allows the probe to be firmly fixed in the required position using bolts and other connecting parts, ensuring the probe remains stable during operation. When cleaning and maintenance of the probe is required, due to the threaded connection characteristics of the internal threaded cylinder and the threaded column, the probe can be easily removed from the installation plate without disassembling the bolts, avoiding the trouble caused by bolt removal. This not only saves maintenance time but also reduces the probability of bolt damage and loosening caused by frequent bolt disassembly, making probe cleaning and maintenance more convenient and efficient. This ensures the probe can operate stably for a long time, providing reliable support for the concentration detection of spirulina culture medium. Attached Figure Description

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.

[0017] like Figures 1 to 4 As shown, this utility model provides an optical real-time concentration detection probe for spirulina culture medium, including a waterproof shell 1. A protective lens 2 is threadedly connected to the left side of the waterproof shell 1. A mounting ring 3 is fixedly connected to the left side inside the waterproof shell 1. An LED light source group 4 is fixedly connected to the left side of the mounting ring 3. The LED light source group 4 includes several red, blue, and green lights arranged in an alternating ring. A power module 5 is fixedly connected to the right side of the mounting ring 3. The power module 5 is electrically connected to an external power supply device through a wire passing through the waterproof shell 1. The contact surface between the wire and the waterproof shell 1 is filled with waterproof sealant to prevent water leakage at the wire passage. A heat spreader 6 is fixedly connected inside the waterproof shell 1 and adheres to the right side of the power module 5. Several LED lights arranged in an alternating ring are fixedly connected to the right side of the heat spreader 6. The waterproof housing 1 has uniformly distributed annular heat dissipation fins 7, the outer side of which extends to the outside of the waterproof housing 1. A photosensitive module group 8 is fixedly connected to the right side inside the waterproof housing 1. The photosensitive module group 8 includes a photosensitive sensor, a data processing module, and a wireless transmission module. The input end of the photosensitive sensor is on the same axis as the center of the protective lens 2, and is used to accurately receive light change signals. The data processing module is used to analyze the signals received by the photosensitive sensor and transmit them to the peripheral receiving device through the wireless transmission module. The power module 5 is electrically connected to the LED light source group 4 and the photosensitive module group 8 through wires. A bottom cover 9 is threadedly connected to the right side of the waterproof housing 1. A flange ring 10 is fixedly connected to the right side of the bottom cover 9. An installation structure is provided on the right side of the bottom cover 9.

[0018] refer to Figure 2The installation structure includes an internally threaded cylinder 11 fixedly connected to the center of the right side of the bottom cover 9. The internally threaded cylinder 11 is internally threaded with a threaded post 12. The right side of the threaded post 12 is fixedly connected with an installation plate 13. The four corners of the installation plate 13 are provided with installation holes. The inner and outer surfaces of the internally threaded cylinder 11 and the surface of the threaded post 12 are all provided with an anti-rust coating.

[0019] As a technical optimization of this utility model, by setting the mounting plate 13 and the mounting holes at its four corners, the probe can be firmly fixed in the required position with the help of bolts and other connecting parts, ensuring that the probe remains stable during operation. When the probe needs to be cleaned and maintained, due to the threaded connection characteristics of the internal threaded cylinder 11 and the threaded column 12, the probe can be easily removed from the mounting plate 13 without disassembling the bolts on the mounting plate 13, avoiding the trouble caused by disassembling the bolts. This not only saves maintenance time, but also reduces the probability of bolt damage and loosening caused by frequent bolt disassembly, making the cleaning and maintenance of the probe more convenient and efficient, thereby ensuring that the probe can operate stably for a long time and providing reliable support for the concentration detection of spirulina culture medium.

[0020] refer to Figure 2 The waterproof housing 1 has a heat insulation cylinder 14 inside. The inner surface of the mounting ring 3 is fixedly connected to the left side surface of the heat insulation cylinder 14, and the right side surface of the heat insulation cylinder 14 is attached to the inner wall of the waterproof housing 1. The inner sides of the power module 5, the heat spreader 6 and the heat dissipation fins 7 are all attached to the surface of the heat insulation cylinder 14. The heat insulation cylinder 14 has a filter 15 fixedly connected to the left side of the input end of the photosensitive module group 8, which is used to allow only specific wavelengths of light to pass through, thereby improving the selectivity of the detection.

[0021] As a technical optimization of this utility model, by setting up a heat insulation cylinder 14 to isolate the power module 5, heat spreader 6, and heat dissipation fins 7 from the photosensitizing module group 8, the influence of the heat generated by the power module 5 and other components on the photosensitizing module group 8 can be effectively reduced, ensuring the temperature stability of the working environment of the photosensitizing module group 8, thereby improving the detection accuracy. The filter 15 fixed inside the heat insulation cylinder 14 only allows light of specific wavelengths to pass through, which can eliminate the interference of other irrelevant wavelengths of light, improve the selectivity of detection, and make the detection results more accurately reflect the actual concentration of the spirulina culture medium, providing more reliable data support for accurately judging the harvest time.

[0022] refer to Figure 1 The protective lens 2 includes an internal threaded ring 16 that is threaded to the left side of the waterproof housing 1. The left side of the internal threaded ring 16 is fixedly connected to a high-definition explosion-proof glass cover 17. Waterproof sealant is provided at the connection between the high-definition explosion-proof glass cover 17 and the internal threaded ring 16.

[0023] As a technical optimization of this utility model, the threaded connection between the internal threaded ring 16 and the waterproof housing 1 facilitates the installation and disassembly of the protective lens 2, making maintenance and replacement easier. The high-definition explosion-proof glass cover 17 effectively protects internal components such as the LED light source group 4 from external impacts, while ensuring clear and accurate light transmission without affecting light propagation and detection performance. The waterproof sealant at the connection between the high-definition explosion-proof glass cover 17 and the internal threaded ring 16 further enhances the waterproof performance of the protective lens 2, preventing liquid from entering the waterproof housing 1 and ensuring the normal operation of the internal electrical components of the probe.

[0024] refer to Figure 2 A sealing strip 18 is fixedly connected to the outer surface of the heat dissipation fin 7. The surface of the sealing strip 18 is fixedly connected to the inner wall of the waterproof housing 1. Several evenly distributed heat dissipation holes are opened on the outer side of the heat dissipation fin 7.

[0025] As a technical optimization of this utility model, by setting a sealing strip 18 fixed to the outer surface of the heat dissipation fin 7 and fixedly connecting it to the inner wall of the waterproof shell 1, liquid can be effectively prevented from entering the interior of the waterproof shell 1 through the gap between the heat dissipation fin 7 and the waterproof shell 1, thus enhancing the waterproof performance of the probe. The several evenly distributed heat dissipation holes opened on the outer side of the heat dissipation fin 7 increase the heat dissipation area and improve the heat dissipation efficiency, which can dissipate the heat generated by the device more quickly, ensuring that the internal components of the probe work in a suitable temperature environment, extending the service life of the components, and also improving the stability and accuracy of the detection.

[0026] refer to Figure 2 A sealing ring 19 is fixedly connected to the right side of the internal threaded ring 16 and the left side of the bottom cover 9, and the inner sides of the two sealing rings 19 are respectively attached to the left and right ends of the waterproof shell 1.

[0027] As a technical optimization of this utility model, sealing rings 19 fixed to the right side of the internal threaded ring 16 and the left side of the bottom cover 9 are respectively attached to the left and right ends of the waterproof shell 1, forming a good sealing structure. This sealing structure can effectively prevent liquid from entering the interior from both ends of the waterproof shell 1, further enhancing the waterproof performance of the probe, ensuring that the electrical and optical components inside the probe are not corroded by liquid, guaranteeing the normal operation of the probe and the accuracy of the detection results, while also extending the service life of the probe and reducing maintenance costs.

[0028] The working principle and usage process of this utility model are as follows: First, the probe is installed in a suitable position using the mounting structure. It is then fixed with bolts using the mounting holes at the four corners of the mounting plate 13. The threaded connection between the internal threaded cylinder 11 and the threaded post 12 allows for flexible adjustment of the installation position. After the probe is installed, the external power supply device supplies power to the power module 5 via wires. The waterproof sealant at the contact surface between the wires and the waterproof outer shell 1 prevents liquid intrusion. The power module 5 supplies power to the LED light source group 4 and the photosensor module group 8. The LED group contains alternating red, blue, and green lights that emit light of specific wavelengths. This light passes through the protective lens 2 and is directed towards the spirulina culture medium. As the light passes through the culture medium, its intensity changes due to the absorption characteristics of spirulina for different wavelengths of light. The photosensor in the photosensor module group 8 receives the signal indicating the change in light intensity after passing through the culture medium. Its input end is aligned with the center of the protective lens 2 to ensure accurate light reception. The data processing module analyzes the signal received by the photosensor and calculates the concentration of spirulina in the culture medium in real time based on the correlation between the degree of light absorption and the concentration of spirulina. The concentration data is then transmitted wirelessly to an external receiving device, allowing operators to monitor the situation in real time. During operation, the heat spreader 6 and heat sink 7 dissipate heat generated by the power module 5, etc., while the heat insulation cylinder 14 reduces the impact of heat on the photosensitive module group 8. The filter 15 allows only specific wavelengths of light to pass through, improving detection selectivity. When the probe needs cleaning and maintenance, it can be easily removed from the mounting plate 13 through the threaded connection between the internal threaded cylinder 11 and the threaded post 12 without removing the bolts.
