Technical Field
[0001] This utility model relates to the field of marine microbial cultivation technology, specifically a polar marine microbial cultivation device. Background Technology
[0002] The ocean is the cradle of life, boasting biodiversity far exceeding that of terrestrial organisms. Marine life includes marine animals, plants, and microorganisms. Covering approximately 71% of the Earth's surface, the ocean is an open, dynamic, and complex ecosystem. The complexity of the ocean's unique physical and chemical factors creates the complexity of life activities, resulting in biodiversity in species resources, gene function, and ecological function. The ocean is extremely rich in biological resources, containing a wide variety of bioactive substances, and is providing humanity with abundant food, diverse materials, and raw materials. It is renewable and possesses enormous development potential. Marine microorganisms originate from the marine environment, require seawater for normal growth, and can survive for extended periods under oligotrophic and low-temperature conditions, continuously reproducing. These microorganisms primarily include eukaryotic microorganisms, prokaryotic microorganisms, and acellular microorganisms. Antarctica, as an important part of the Earth, contains extremely rich polar marine microbial resources. As an important component of polar resources, it has become an important target for development by various countries. Cultivating polar marine microorganisms and their active substances is extremely important in plant disease control, biological control, and biomedicine. Existing polar marine microbial cultivation devices usually place microorganisms in petri dishes containing culture medium, place the petri dishes in a cultivation cabinet, and use supplemental lighting and continuous pumping of cold air to simulate the polar environment and promote the reproduction of microorganisms. In this way, the traditional polar marine microbial cultivation devices have fixed lighting and cooling devices, and the culture medium does not move inside the petri dish. The microorganisms do not receive sufficient light and cooling effects, resulting in low microbial reproduction efficiency. Therefore, we propose a polar marine microbial cultivation device. Utility Model Content

[0016] 1. Through the threaded connection between the lead screw and the frame, and the drive of motor 2, the frame can move up and down, thereby driving the nozzle and supplementary light to move up and down.

[0027] The working principle of the polar marine microbial cultivation device provided by this utility model is as follows: When cultivating polar marine microorganisms, open cabinet door 2, select a matching mounting bracket 57, and fix the mounting bracket 57 to the upper end of connecting rod 53 using threads. Then, sterilize the inside of the shell 1 to maintain the microbial breeding environment as sterile as possible. Close cabinet door 2, and the microcontroller 4 controls the operation of ultraviolet lamp 64. Ultraviolet lamp 64 emits ultraviolet light, which continuously irradiates the inner wall and internal structure of shell 1. After a period of time, turn off ultraviolet lamp 64, open cabinet door 2 again, and insert the culture dish containing microorganisms into mounting bracket 57. When cabinet door 2 is closed, the external compressor operates, continuously pumping cold air into the frame 62. This air is then evenly sprayed into the housing 1 through nozzles 63. Excess gas is discharged through the air vent with a filter at the top of housing 1, ensuring a relatively stable air pressure between the inside and outside environments. The microcontroller 4 controls the supplementary light 65 to provide sufficient illumination for the microorganisms inside the culture dish. Simultaneously, the microcontroller 4 controls motor 66 to operate. The output shaft of motor 66 drives the lead screw 61 to rotate forward, causing the frame 62 to move downwards along with the lead screw 61, simultaneously moving the nozzles 63 and supplementary light 65 until the frame 62 reaches the designated position. At this point, the microcontroller 4... The second control motor 66 operates, and its output shaft drives the lead screw 61 to reverse. The frame 62 moves upward with the rotation of the lead screw 61, simultaneously moving the nozzle 63 and the supplementary light 65 upward. This cycle repeats. Simultaneously, the microcontroller 4 controls the first motor 58 to operate. The output shaft of the first motor 58 drives the drive disk 54 to rotate, and the ball seat 55 also rotates accordingly. Since the ball seat 55 is located on the upper left side of the drive disk 54, it is eccentrically positioned above the drive disk 54. Because the connecting rod 53 is rotatably connected to the inner wall of the ball seat 51 via the ball head 52 in the middle of its outer surface, the connecting rod 53 is limited at the ball head 52 by the ball seat 51. Therefore, when… When the ball seat 55 rotates to the left, the locking seat 57 at the upper end of the connecting rod 53 and the culture dish deflect to the right. When the ball seat 55 rotates to the rear, the locking seat 57 at the upper end of the connecting rod 53 and the culture dish deflect forward. When the ball seat 55 rotates to the right, the locking seat 57 at the upper end of the connecting rod 53 and the culture dish deflect to the left. When the ball seat 55 rotates to the front, the locking seat 57 at the upper end of the connecting rod 53 and the culture dish deflect backward. This cycle repeats, creating a shaking state for the culture dish. The microorganisms continuously shake inside the culture dish. Combined with the illumination from the up-and-down moving supplemental light 65, the light and cooling effect inside the shell 1 can be more sufficient, thereby improving the reproduction efficiency of microorganisms.
[0028] It is worth noting that the microcontroller 4 disclosed in the above embodiments is an S7-200 microcontroller, motor 58 is a 35BYJ46 motor, ultraviolet lamp 64 is a T815W ultraviolet lamp, supplementary light 65 is an LED lamp, and motor 66 is an SPS42E234-1.27-151 motor. The microcontroller 4 controls the operation of motor 58, ultraviolet lamp 64, supplementary light 65 and motor 66 using methods commonly used in the prior art.
