[0002] Selenium is considered the third essential trace nutrient after iodine and zinc. It has antioxidant, anti-cancer and immunity-enhancing effects. Carotenoids, mainly including β-carotene, are important fat-soluble compounds that can only be synthesized in plants and microorganisms. The concentration of β-carotene in algae is higher than that in carrots. By enriching selenium in algae and combining it with carotenoids, selenoprotein carotenoids with strong physiological activity can be formed, which is of great significance in the fields of biomedicine and food. When cultivating microalgae containing selenoprotein carotenoids, changes in external light and temperature as well as the concentration of carbon dioxide will affect the reproduction state of the microalgae. Inappropriate changes in these factors may lead to restricted growth of the microalgae, thereby reducing its selenoprotein carotenoid content. In view of this, the utility model proposes a microalgae cultivation device containing selenoprotein carotenoids. Utility Model Content

[0029] Example

[0030] like Figures 1 to 3 As shown, the present invention proposes a selenoprotein-carotenoid microalgae cultivation device comprising a housing 1, with a transparent lid 2 rotatably connected to the top of the housing 1 for convenient observation of microalgae growth. A handle 21 is mounted on the top of the lid 2 for easy opening. The housing 1 defines a cultivation trough 11, within which a cultivation tank 3 is placed. The microalgae in the cultivation tank 3 are then cultivated.

[0031] Specifically, the cultivation device includes a constant-temperature heating unit 7 installed in the housing 1. The top of the constant-temperature heating unit 7 contacts the cultivation tank 3 and regulates the temperature, maintaining the microalgae cultivation environment between 20°C and 30°C, ensuring a suitable temperature range. A light strip 8 is installed on the inner wall of the cultivation tank 11 and surrounds the outer periphery of the cultivation tank 3. It ensures an appropriate light intensity and photoperiod to promote photosynthesis. It also uses LED lights with specific wavelengths, such as blue and red light, to enhance carotenoid synthesis. An air inlet pipe 9, located directly above the cultivation tank 3 and mounted in the housing lid 2, regularly supplies carbon dioxide to the cultivation tank 11, promoting photosynthesis and improving the growth efficiency of the microalgae. This ensures a uniform gas supply and avoids localized gas shortages. Furthermore, an air outlet hole is provided in the housing 1, communicating with the cultivation tank 11, to prevent excessive air pressure within the cultivation tank 11.

[0032] Furthermore, the above-mentioned cultivation device also includes a positioning mechanism 4 disposed in the housing 1. The positioning mechanism 4 is used to position the cultivation pot 3 so that the cultivation pot 3 remains in the center. The positioning mechanism 4 includes two sets of positioning plates 41 disposed on either side of the cultivation pot 3. The side of the positioning plates 41 closer to the cultivation pot 3 is mounted with a rubber pad 42 to prevent damage to the surface of the cultivation pot 3. The side of the positioning plates 41 farther from the cultivation pot 3 is fixedly connected to two sets of sliding rods 43. The sliding rods 43 are slidably connected to the housing 1, ensuring smooth movement of the positioning plates 41. The outer ring of the sliding rods 43 is mounted with a first spring 44. The first spring 44 is disposed in the cultivation groove 11. The first spring 44 is used to release the elastic force, causing the positioning plates 41 to approach the cultivation pot 3 and compress the rubber pad 42, thereby fixing the position of the cultivation pot 3. Two sets of cavities 45 are defined within the housing 1. Synchronizing plates 46 are mounted within these cavities. These plates are fixedly connected to the ends of the two sets of slide bars 43 facing away from the positioning plates 41. When these plates move, the slide bars 43 drive the positioning plates 41 to move. A moving block 47 is mounted on the side of the synchronizing plates 46 facing away from the slide bars 43. The moving block 47 moves synchronously with the synchronizing plates 46. A first connecting rod 48 is fixedly connected to the end of the moving block 47 facing away from the synchronizing plates 46. The first connecting rod 48 is slidably connected to the housing 1. A first pull ring 49 is fixedly connected to the end of the first connecting rod 48 facing away from the moving block 47. When the first pull ring 49 moves, the first connecting rod 48 drives the moving block 47 to move, thereby moving the positioning plates 41 away from the culture pot 3 and facilitating removal of the culture pot 3.

[0033] Furthermore, the aforementioned limiting assembly 5 installed in the housing 1 is used to limit the positioning mechanism 4 to facilitate removal of the cultivation pot 3. The limiting assembly 5 includes a locking block 51 disposed above the movable block 47. The locking block 51 is slidably connected to the housing 1. The bottom of the locking block 51 is tilted, and the top of the movable block 47 is provided with a locking slot 52 corresponding to the locking block 51. The locking block 51 can be locked in the locking slot 52 to limit the movable block 47 and prevent the first spring 44 from releasing its elastic force. A second connecting rod 53 is fixedly connected to the top of the locking block 51. The second connecting rod 53 is slidably connected to the housing 1. A second pull ring 54 is mounted on the top of the second connecting rod 53. The second pull ring 54 is connected to the locking block 51 via the second connecting rod 53, facilitating the removal of the locking block 51 from limiting the movable block 47. A spring chamber 55 opened in the box body 1 is also provided at the position of the second connecting rod 53, and a movable plate 56 is slidably connected in the spring chamber 55. The movable plate 56 is fixedly connected to the second connecting rod 53. The outer ring of the second connecting rod 53 is sleeved with a second spring 57, and the second spring 57 is arranged above the movable plate 56. The second spring 57 is used to release the elastic force so that the block 51 is located in a position to limit the movable block 47.

[0034] Finally, the cultivation device also includes a homogenizing mechanism 6 mounted on the lid 2. This mechanism is used to agitate the microalgae in the cultivation tank 3. This mechanism comprises a servo motor 61 mounted on the top of the lid 2. The output end of the servo motor 61 extends through the lid 2 and is detachably connected to a rotating rod 62. When activated, the servo motor 61 rotates the rotating rod 62. The detachable connection facilitates removal and cleaning of the rotating rod 62. Multiple sets of mixing rods 63 are mounted on the outer ring of the rotating rod 62. Rotation of the rotating rod 62 drives the mixing rods 63 to rotate synchronously, agitating the microalgae in the cultivation tank 3 and ensuring uniform distribution of heat, light, and carbon dioxide to the microalgae.

[0035] In this embodiment, the cultivation pot 3 is placed in the cultivation slot 11. The second pull ring 54 is pulled upward, which, via the second connecting rod 53, drives the block 51 upward, causing it to move away from the movable block 47. The first spring 44 then releases its elastic force, pulling the positioning plate 41 toward the cultivation pot 3 while simultaneously squeezing the rubber pad 42. The two sets of positioning plates 41 clamp the cultivation pot 3, securing its position. The lid 2 is closed, and the rotating rod 62 and mixing rod 63 enter the cultivation pot 3. The servo motor 61 is activated to rotate the rotating rod 62 and mixing rod 63, causing the microalgae to continuously move. At this point, the light intensity of the light strip 8 can be controlled, and the constant temperature heating unit 7 can be used to maintain the microalgae's growth temperature at an appropriate level. Carbon dioxide is then introduced into the cultivation pot 3 through the air inlet pipe 9, ensuring stable microalgae growth. The growth of the microalgae can also be observed through the lid 2. After the microalgae are cultivated in the cultivation tank 3, the first pull ring 49 is pulled. This, via the first connecting rod 48, moves the movable block 47, which in turn moves the positioning plate 41 away. Simultaneously, as the movable block 47 moves, the second spring 57 releases its force, causing the retaining block 51 to engage in the retaining slot 52, preventing the first spring 44 from releasing its force. At this point, the lid 2 can be opened, the cultivation tank 3 removed from between the two sets of positioning plates 41, and a new set of cultivation tanks 3 can be replaced and placed in the cultivation trough 11. The rotating rod 62 and mixing rod 63 can also be removed for cleaning. The second pull ring 54 is then pulled upward. This, via the second connecting rod 53, moves the retaining block 51 away from the retaining slot 52, releasing the force of the first spring 44 and allowing the positioning plate 41 to reposition the cultivation tank 3, facilitating the cultivation of the next batch of microalgae.

[0036] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
