Description

Technical Field

[0001] This invention relates to the technical field of algae cultivation, specifically to a dynamic control method and intelligent cultivation device for algae extract cultivation. Background Technology

[0002] Algae can be composed of one or a few cells, or many cells aggregated into tissue-like structures. Among them, green algae are the largest phylum of algae. Their cells are similar to those of higher plants, with cell nuclei and chloroplasts, and similar pigments, nutrient storage, and cell wall components. Green algae are of great significance in the study of plant evolution. Moreover, many green algae can be used as feed, and some can be eaten or have algin extracted. An algae cultivation device described in the prior art includes a cultivation box, which comprises an outer box, an inner box, and a lid. The lid covers the outer box and the inner box, and a sealing structure is provided between the lid and the inner box to seal the inner box. Cool white fluorescent lamps and ultraviolet lamps are fixed on the inner side wall and the inner bottom surface of the outer box. Several fixing rods of different lengths are vertically fixed on the bottom surface of the inner box, and a transparent glass cover is fixed to the upper end of the fixing rods. Cool white fluorescent lamps are installed inside the transparent glass cover.

[0003] Although the above-mentioned technology can increase algae production and control its growth, during the cultivation period, green algae are easily attached to the inner wall of the device and the outer wall of the light-emitting components, which reduces the light transmittance, causes uneven light distribution, makes it difficult to ensure the photosynthetic efficiency of green algae, and thus affects the growth of green algae and the subsequent extraction of extracts. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a dynamic regulation method and intelligent cultivation device for the cultivation of algal extracts, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for dynamic regulation of algal extract culture, comprising the following steps: Step 1: Detection of green algae growth environment. The sensor group located in the culture tank is activated to detect the growth status of green algae and the culture environment, and transmits the data to the main control board in the control box in real time. The main control board analyzes and judges the data. Step 2: Light control. When it is determined that the green algae are under-lit, the central lamp tube at the top of the culture tank and the symmetrical fluorescent lamp group on the outside are activated, and the drive motor of the rotating component is working. Through tooth meshing, the sleeve plate is rotated on the culture tank. The sleeve plate will drive the inserted tank cover and the two vertical plates to rotate slowly, ensuring that the light evenly covers all areas inside the tank. At the same time, the light parameters of the lamp tube and fluorescent lamp group are dynamically and finely adjusted according to the data of the sensor group to adapt to the photosynthetic needs of the green algae. Step 3: Cleaning and Control. When the light transmittance is lower than the preset value, it indicates that there is a lot of green algae attached to the outer wall of the lamp cover and the inner wall of the culture tank. At this time, start the electric telescopic rod to control the connecting rod and the ring scraper to move down until the connecting rod and the ring rod are magnetically connected. During the downward movement of the ring scraper, the green algae attached to the outer wall of the lamp cover will be scraped off. Furthermore, since the lid rotates along with the sleeve, it will cause the disturbance rod and the arc-shaped scraper to rotate. The arc-shaped scraper scrapes off the green algae attached to the inner wall of the culture tank to ensure light transmission. At the same time, the disturbance rod will disturb the culture medium during rotation to further ensure uniform light exposure, provide a good environment for the growth of green algae, and improve the extraction efficiency of subsequent extracts.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of the present invention will now be described.

[0020] In this embodiment, please refer to Figure 1 - Figure 7 As shown, a method for dynamic regulation of algal extract culture includes the following steps: Step 1: Detection of green algae growth environment. The sensor group located in the culture tank 1 is activated to detect the growth status of green algae and the culture environment. The data is transmitted in real time to the main control board in the control box 103, and the main control board analyzes and judges the data. Step 2, Light Control: When it is determined that the green algae are under-lit, the lamp 302 at the top center of the culture tank 1 and the symmetrical fluorescent lamp group on the outside are activated, and the drive motor 501 of the rotating component 5 is working. Through tooth meshing, the sleeve plate 6 is rotated on the culture tank 1. The sleeve plate 6 will drive the inserted tank cover 2 and the two vertical plates 7 to rotate slowly, ensuring that the light evenly covers all areas inside the tank. At the same time, the light parameters of the lamp 302 and the fluorescent lamp group are dynamically and finely adjusted according to the data of the sensor group to adapt to the photosynthetic needs of the green algae. Step 3: Cleaning and Control. When the light transmittance is lower than the preset value, it indicates that there is a lot of green algae attached to the outer wall of the lamp cover 301 and the inner wall of the culture tank 1. At this time, the electric telescopic rod 203 is activated to control the connecting rod 204 and the annular scraper 2041 to move down until the connecting rod 204 and the annular rod 403 are magnetically connected. During the downward movement of the annular scraper 2041, the green algae attached to the outer wall of the lamp cover 301 is scraped off. Since the lid 2 rotates along with the sleeve plate 6, it will drive the disturbance rod 401 and the arc scraper 402 to rotate. The arc scraper 402 scrapes off the green algae attached to the inner wall of the culture tank 1 to ensure light transmission. At the same time, the disturbance rod 401 will disturb the culture medium during the rotation process to further ensure uniform light and provide a good environment for the growth of green algae, thereby improving the extraction efficiency of the subsequent extract.

[0021] It should be noted that the sensor group includes a dissolved oxygen sensor and a light intensity sensor. The dissolved oxygen sensor is used to measure the dissolved oxygen content in the culture medium. Green algae produce oxygen through photosynthesis during their growth, but they also consume oxygen through respiration. Ensuring sufficient dissolved oxygen in the culture medium is crucial for the normal growth of green algae. The light intensity sensor can accurately measure the light intensity inside culture tank 1. Combined with the green algae growth status data, the main control board can dynamically adjust the light parameters of lamp tube 302 and fluorescent lamp group to ensure that the light intensity always meets the photosynthetic needs of green algae. These sensors work together to transmit the data they collect to the main control board in the control box 103 in real time. The main control board performs comprehensive analysis and judgment on this data, thereby achieving precise control of the green algae growth environment and providing strong support for the growth of green algae and the subsequent extraction of extracts.

[0022] Please see Figure 2 - Figure 7As shown in the above embodiments, a dynamic control intelligent culture device for culturing algal extracts will also be provided. A base 101 is fixed to the bottom of the culture tank 1. A base plate 102 is welded to the bottom of the outer wall of the base 101. A control box 103 is mounted on the base plate 102. A tank cover 2 is installed at the opening of the culture tank 1. A perforation 201 is provided in the center of the tank cover 2, through which a lampshade 301 is inserted. A lamp tube 302 is installed inside the lampshade 301. A horizontal lifting plate 303 is provided above the tank cover 2 and the control box 103. A mounting plate 3 is fixed to the upper surface of the lifting plate 303 at the tank cover 2 by screws. The top of the lampshade 301 is through... The lifting plate 303 is fixed to the mounting plate 3 with screws. The lamp tube 302 is connected to the lamp holder on the lower surface of the mounting plate 3. The mounting plate 3 has heat dissipation holes. The top of the control box 103 is equipped with a hydraulic cylinder 304 by screws. The telescopic ends of the two hydraulic cylinders 304 are fixed to the lifting plate 303 with screws. The lower surface of the lifting plate 303 is symmetrically fixed with abutment rods 305. The bottom ends of the two abutment rods 305 are in rolling contact with the upper surface of the tank cover 2 through embedded balls. The top of the outer wall of the culture tank 1 is slidably installed with a sleeve plate 6. Several insertion rods 601 are fixed at the top of the sleeve plate 6. The bottom of the tank cover 2 is provided with insertion holes that match the insertion rods 601. A vertical shaft 4 is rotatably mounted on the center of the inner bottom wall of the culture tank 1. Multiple disturbance rods 401 are fixed to the outer wall of the vertical shaft 4. Sensor groups electrically connected to the control box 103 are mounted on the disturbance rods 401, and the sensor groups are installed on the middle section of the intermediate disturbance rod 401. Two arc-shaped scrapers 402 are symmetrically arranged on the inner wall of the culture tank 1, and both arc-shaped scrapers 402 are fixedly connected to the disturbance rods 401. The top of the vertical shaft 4 contacts the bottom of the lampshade 301. Electrically controlled lowering connecting rods 204 are symmetrically arranged below the culture tank 1. Electric telescopic rods 203 are screwed onto both sides of the lampshade 301 on the upper surface of the tank cover 2. The telescopic ends of the two electric telescopic rods 203 are fixedly connected to the corresponding connecting rods 204. An annular scraper 2041 is fixed between the two connecting rods 204 and is sleeved on the outer wall of the lampshade 301. The lower surface of the two connecting rods 204... A magnet is installed inside the end. A ring rod 403 is integrally fixed between the disturbance rods 401 set on both sides of the top of the vertical shaft 4. An iron sheet is installed inside the ring rod 403. The magnet is magnetically connected to the iron sheet. The magnet is a moderately strong magnet to avoid the problem of easy rotation and fall off due to insufficient magnetic force, or inability to separate due to excessive magnetic force. Vertical plates 7 are symmetrically arranged on the outside of the culture tank 1. Fluorescent lamp groups are installed on the side of the two vertical plates 7 near the culture tank 1. A rotating component 5 is provided on the outer wall of the sleeve plate 6. The rotating component 5 is used to control the rotation of the two vertical plates 7 and the disturbance rods 401 to achieve all-round light coverage and stirring of the green algae growth environment, and to clean the green algae attached to the inner wall of the culture tank 1 and the outer wall of the lamp cover 301. A feeding port 202 is provided on the tank cover 2. The height of the feeding port 202 and the two electric telescopic rods 203 is less than the height of the abutment rod 305. A control panel 1032 is installed on the side wall of the control box 103. The bottom of the outer wall of the culture tank 1 is provided with a discharge port for discharging residue, and the length of the discharge port is less than the distance between the outer wall of the culture tank 1 and the vertical plate 7. Discharge can be carried out through an external pipe. A ventilation chamber can also be opened inside the vertical shaft 4, and several one-way air valves communicating with the ventilation chamber are set on the outer wall of the vertical shaft 4. The ventilation chamber is connected to the external aeration device through an air pipe passing through the base 101, so that aeration can be carried out when the oxygen content is insufficient.

[0023] If the sensor group detects that the oxygen content in the culture tank 1 is insufficient, the external aeration device is activated. Gas enters the ventilation chamber inside the vertical shaft 4 through the air pipe, and then is evenly discharged into the culture solution through the one-way air valve on the outer wall of the vertical shaft 4 to achieve aeration and oxygen supplementation, and avoid the growth of green algae due to lack of oxygen.

[0024] When cultivating green algae, suitable culture medium and nutrients are added into the culture tank 1 through the feeding port 202 to provide necessary nutrients for the growth of green algae. After the feeding is completed, the main control board in the control box 103 is started, and the sensor group begins to monitor the growth status of green algae and the culture environment in real time. When insufficient light is detected and light supplementation is required, the lamp tube 302 at the top center of the culture tank 1 and the fluorescent lamp group symmetrically arranged on the outside of the culture tank 1 are started synchronously. At the same time, the rotating component 5 starts to work, driving the sleeve plate 6 to slowly rotate on the top of the outer wall of the culture tank 1. When the sleeve plate 6 rotates, the plug rod 601 and the plug hole are connected to drive the tank cover 2 to rotate synchronously. At the same time, the sleeve plate 6 drives the two vertical plates 7 to rotate synchronously through the fixing plate 504. The T-shaped slider 701 at the bottom of the vertical plate 7 slides on the slide groove 1011 of the base 101 to ensure that the vertical plate 7 rotates smoothly. This drives the fluorescent lamp group on the vertical plate 7 to rotate around the culture tank 1. Together with the lamp tube 302 at the top, it ensures that the light evenly covers all areas inside the culture tank 1. The main control board dynamically fine-tunes the light parameters of the lamp tube 302 and the fluorescent lamp group according to the data transmitted by the sensor group to adapt to the photosynthetic needs of green algae at different growth stages. During this process, when the main control board determines that the light transmittance of culture tank 1 is lower than the preset value based on the data from the sensor group, it indicates that there is a lot of green algae attached to the outer wall of lamp cover 301 and the inner wall of culture tank 1, which affects the lighting effect. At this time, the main control board controls the two electric telescopic rods 203 on the tank cover 2 to start synchronously. The telescopic end of the electric telescopic rod 203 extends, driving the connecting rod 204 and the annular scraper 2041 to move down slowly. During the downward movement of the annular scraper 2041, its inner wall is tightly attached to the outer wall of lamp cover 301, scraping off the green algae attached to the outer wall of lamp cover 301. When the connecting rod 204 moves down to align with the annular rod 403, the magnet inside the connecting rod 204 and the iron sheet inside the annular rod 403 achieve magnetic connection, completing the docking of the connecting rod 204 and the disturbance rod 401. Since the lid 2 rotates synchronously with the sleeve plate 6, the rotation of the lid 2 drives the annular rod 403 to rotate synchronously via the electric telescopic rod 203 and connecting rod 204, which in turn drives the vertical shaft 4 and the disturbance rod 401 to rotate. When the disturbance rod 401 rotates, it drives the arc-shaped scraper 402 to rotate synchronously. The arc-shaped scraper 402 fits tightly against the inner wall of the culture tank 1, scraping off the green algae attached to the inner wall of the culture tank 1, ensuring the light transmittance of the device. It also eliminates the need for an additional power source, achieving integrated operation of cleaning, lighting, and stirring, reducing component redundancy, and lowering the energy consumption of the device. The control panel 1032 plays an important role in the entire cultivation process. Operators can view the data collected by the sensor group in real time through the control panel 1032, such as the dissolved oxygen content of the culture medium and the light intensity, and can manually adjust the control parameters of the main control board according to the actual situation. This allows for precise monitoring of the growth status and cultivation environment parameters of green algae, as well as achieving uniform light coverage within the tank. It also ensures stable light transmittance of the device, guarantees a consistent growth environment for green algae, meets the photosynthetic growth requirements of green algae, and thus improves the extraction efficiency of subsequent algal extracts.

[0025] Please see Figure 6 As shown, the rotating assembly 5 includes a drive motor 501. The top of the control box 103 near the culture tank 1 has a mounting groove 1031. The drive motor 501 is fixed to the bottom of the mounting groove 1031 by screws. The output end of the drive motor 501 is fixedly fitted with a drive wheel 502. The top of the outer wall of the sleeve plate 6 is fixedly fitted with a toothed ring 503. One side of the toothed surface of the drive wheel 502 is meshed with the toothed ring 503. The bottom of the outer wall of the sleeve plate 6 is symmetrically welded with a fixing plate 504. The top ends of the two vertical plates 7 are fixed to the corresponding fixing plates 504 with screws. The outer wall of the base 101 has a sliding groove 1011. T-shaped sliders 701 are symmetrically slidably mounted on the sliding groove 1011. The top ends of the two T-shaped sliders 701 are fixed to the bottom ends of the corresponding vertical plates 7 with screws. The distance between the control box 103 and the base 101 is greater than the thickness of the end face of the T-shaped slider 701.

[0026] The drive motor 501 operates, driving the drive wheel 502 to rotate. Since the drive wheel 502 is engaged with the gear ring 503 on the outer wall of the sleeve plate 6, its rotation causes the sleeve plate 6 to slowly rotate on the top of the outer wall of the culture tank 1. The sleeve plate 6, through the fixing plate 504, drives the two vertical plates 7 to rotate synchronously. The T-shaped slider 701 at the bottom of the vertical plate 7 slides on the groove 1011 of the base 101. During this process, the rotation speed and angle of the vertical plate 7 can be precisely adjusted by the main control board by controlling the speed and direction of the drive motor 501 according to the actual growth of the algae and the light requirements. Simultaneously, to ensure the stable operation of the rotating component 5, the drive motor 501 can be a servo motor with high precision and low noise characteristics, and shock-absorbing pads are installed in the mounting groove 1031 to reduce the impact of vibrations generated during motor operation on other components of the device.

[0027] The working principle of this invention is as follows: During the cultivation of green algae, suitable culture medium and nutrients are added into the cultivation tank 1 through the feeding port 202 to provide the necessary nutrients for the growth of green algae. After the feeding is completed, the main control board in the control box 103 is activated, and the sensor group begins to monitor the growth status of green algae and the cultivation environment in real time. When insufficient light is detected and light supplementation is required, the lamp tube 302 at the top center of the cultivation tank 1 and the fluorescent lamp group symmetrically arranged on the outside of the cultivation tank 1 are activated synchronously. At the same time, the drive motor 501 works, and the drive motor 501 drives the drive wheel 502 to rotate. Since the drive wheel 502 is meshed with the toothed ring 503 on the outer wall of the sleeve plate 6, the rotation of the drive wheel 502 drives the sleeve plate 6 to rotate. Plate 6 rotates slowly on the top of the outer wall of culture tank 1. When plate 6 rotates, the tank cover 2 rotates synchronously through the insertion of rod 601 and insertion hole. At the same time, plate 6 drives two vertical plates 7 to rotate synchronously through fixing plate 504. T-shaped slider 701 at the bottom of vertical plate 7 slides on the slide groove 1011 of base 101 to ensure that vertical plate 7 rotates smoothly. This drives the fluorescent lamp group on vertical plate 7 to rotate around culture tank 1. Together with the lamp tube 302 at the top, it ensures that the light covers all areas inside culture tank 1 evenly. The main control board dynamically fine-tunes the light parameters of lamp tube 302 and fluorescent lamp group according to the data transmitted by sensor group to adapt to the photosynthetic needs of green algae at different growth stages. During this process, when the main control board determines, based on data from the sensor group, that the light transmittance of culture tank 1 is lower than the preset value, it indicates that there is a lot of green algae attached to the outer wall of lampshade 301 and the inner wall of culture tank 1, affecting the lighting effect. At this time, the main control board controls the two electric telescopic rods 203 on the tank cover 2 to start synchronously. The telescopic ends of the electric telescopic rods 203 extend, driving the connecting rod 204 and the annular scraper 2041 to move slowly downward. During the downward movement of the annular scraper 2041, its inner wall fits tightly against the outer wall of lampshade 301, scraping off the green algae attached to the outer wall of lampshade 301. When the connecting rod 204 moves down to the position of the annular rod 403... At the same time, the magnet inside the connecting rod 204 and the iron sheet inside the ring rod 403 are magnetically connected, completing the docking of the connecting rod 204 and the disturbance rod 401. Since the can lid 2 is rotating synchronously with the sleeve plate 6, when the can lid 2 rotates, it drives the ring rod 403 to rotate synchronously through the electric telescopic rod 203 and the connecting rod 204, which in turn drives the vertical shaft 4 and the disturbance rod 401 to rotate. When the disturbance rod 401 rotates, it drives the arc scraper 402 to rotate synchronously. The arc scraper 402 is in close contact with the inner wall of the culture tank 1, scraping off the green algae attached to the inner wall of the culture tank 1. The scraped green algae gradually disperses with the flow of the culture medium. When the green algae have grown to a suitable stage and algal extract needs to be extracted, stop adding nutrient solution and supplementing light, and shut down the relevant equipment. At this time, open the discharge port at the bottom of culture tank 1, and the culture solution containing green algae will be discharged through an external pipe and transported to the subsequent extraction equipment.
