[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0027] A polymer stability test device for a culture medium, comprising a base 1, on which a test chamber 2 is fixedly installed. A disc 3 is rotatably arranged at the bottom inside the test chamber 2. Uniformly distributed bases 4 are arranged on the disc 3. The bases 4 are annularly distributed. A culture tank 5 is arranged on the base 4. The culture tank 5 is spherical. A chassis 6 is arranged at the bottom of the culture tank 5. The chassis 6 is slidably arranged on the base 4, and a damping is arranged between the chassis 6 and the base 4. A top cover 7 is threadedly connected to the top of the culture tank 5. An optical monitor 8 is arranged on the inner wall of the test chamber 2, and the optical monitor 8 faces the culture tank 5. A driving member 9 for driving the culture tank 5 to shake or move annularly is arranged on the base 1. The driving member 9 includes a motor 91 fixedly installed on the base 1, a driving wheel 92 and a driven wheel 93 rotatably arranged on the base 1, and a belt 94 sleeved on the driving wheel 92 and the driven wheel 93. The end of the output shaft of the motor 91 is fixedly installed with the middle part of the driving wheel 92. The belt 94 is respectively in transmission connection with the driving wheel 92 and the driven wheel 93. The rotating shaft end of the disc 3 is fixedly installed with the middle part of the driven wheel 93.

[0028] The base 1 serves as the support foundation of the entire device and is fixedly installed with a test chamber 2. During use, the operator opens the top covers 7 on the tops of multiple culture tanks 5 and puts polymers into them respectively. Then, the top covers 7 are closed, and the culture tanks 5 are respectively inserted onto the bases 4 of the disc 3 through the chassis 6 at the bottoms of the culture tanks 5. Since there is a damping between the chassis 6 and the base 4, the culture tanks 5 can be limited and fixed through the base 4. Then, the test chamber 2 is closed, and the inside of the test chamber 2 is adjusted to an appropriate temperature to conduct a reaction test on the polymer;

[0029] When the motor 91 on the base 1 operates, the output shaft of the motor 91 drives the driving wheel 9​​2 to rotate. The driving wheel 9​​2 drives the driven wheel 93 to rotate through the belt 94, and the rotating shaft end of the disc 3 is fixedly installed in the middle of the driven wheel 93, so that the disc 3 rotates. The culture tanks 5 placed on the bases 4 move in a circular motion as the disc 3 rotates. When the culture tanks 5 move to the position directly opposite to the optical monitor 8 provided on the inner wall of the test chamber 2, the optical monitor 8 can monitor the culture tanks 5. Since there are multiple culture tanks 5 and they can pass through the optical monitoring area in sequence, the integrity of the monitoring data collection is ensured;

[0030] Starting the small reciprocating motion of the output shaft of the motor 91 can drive the culture tanks 5 to reciprocate and shake, simulating a dynamic culture medium environment. Since the culture tanks 5 are set to be spherical, the shaking effect of the polymer can be improved, and the microorganisms will not be excessively sheared. Then, observe the test reaction of the polymer;

[0031] This polymer stability test device for culture medium can not only drive multiple culture tanks 5 to pass through the optical area for monitoring respectively to ensure the integrity of the monitoring data collection, but also avoid excessive shearing of microorganisms when simulating a dynamic culture medium environment, protect the integrity and physiological activity of microorganisms, and effectively improve the reliability of the test results.

[0032] A vertical rod 10 is fixedly installed at the bottom of the top cover 7, and uniformly distributed and symmetrical stirring rods 11 are fixedly installed on the vertical rod 10;

[0033] When the culture tanks 5 reciprocate and shake the culture medium, the uniformly distributed and symmetrical stirring rods 11 fixedly installed on the vertical rod 10 also move passively, stirring the microorganisms. Since the stirring rods 11 are passively stirred, excessive shearing of the microorganisms can be further avoided.

[0034] Electric push rods 12 are fixedly installed inside the bases 4 where the discs 3 are located, and the end of the output shaft of the electric push rod 12 faces the middle of the chassis 6;

[0035] When it is necessary to take out the culture tank 5, the electric push rod 12 on the disc 3 is activated. The end of the output shaft of the electric push rod 12 is facing the middle of the chassis 6. The output shaft of the electric push rod 12 extends out, slowly pushing the chassis 6 out of the base 4, facilitating the operator to remove the culture tank 5 from the base 4. The setting of the chassis 6 facilitates, on the one hand, stably inserting the culture tank 5 on the base 4, and on the other hand, supporting the culture tank 5 after the culture tank 5 is taken out to keep the culture tank 5 stable.

[0036] A backing plate is laid on the bottom surface of the chassis 6. The backing plate is made of rubber material, and anti-slip patterns are provided on the bottom surface of the backing plate;

[0037] A backing plate is laid on the bottom surface of the chassis 6, and anti-slip patterns are provided on the bottom surface of the backing plate, which can further improve the stability of the placed culture tank 5.

[0038] A control display is provided on the base 1. The control display is electrically connected to the test chamber 2, the optical monitor 8, and the motor 91 respectively;

[0039] A control display is provided on the base 1. The display is electrically connected to key components such as the test chamber 2, the optical monitor 8, and the motor 91. Through the control display, the operator can conveniently set test parameters, start or stop the test process, monitor test data, etc.

[0040] Working principle:

[0041] The base 1 serves as the support foundation of the entire device and is fixedly installed with the test chamber 2. During use, the operator opens the top covers 7 on the tops of multiple culture tanks 5 and puts polymers into them respectively, then closes the top covers 7, and inserts the culture tanks 5 on the base 4 of the disc 3 through the chassis 6 at the bottoms of the culture tanks 5 respectively. Since there is a damping between the chassis 6 and the base 4, the culture tanks 5 can be limited and fixed through the base 4. Then, the test chamber 2 is closed, and the inside of the test chamber 2 is adjusted to an appropriate temperature to conduct a reaction test on the polymer;

[0042] When the motor 91 on the base 1 operates, the output shaft of the motor 91 drives the driving wheel 92 to rotate. The driving wheel 92 drives the driven wheel 93 to rotate through the belt 94, and the rotating shaft end of the disc 3 is fixedly installed with the middle of the driven wheel 93, so that the disc 3 rotates. The culture tanks 5 placed on the base 4 move in a circular motion as the disc 3 rotates. When the culture tanks 5 move to the position directly opposite to the optical monitor 8 provided on the inner wall of the test chamber 2, the optical monitor 8 can monitor the culture tanks 5. Since there are multiple culture tanks 5 and they can pass through the optical monitoring area in sequence, the integrity of the monitoring data collection is ensured;

[0043] The output shaft of the starting motor 91 makes small reciprocating movements, which can drive the culture tank 5 to reciprocate and shake, simulating a dynamic culture medium environment. Since the culture tank 5 is set to be spherical, it can improve the shaking effect of the polymer and will not cause excessive shearing to the microorganisms. Then, observe the test reaction of the polymer;

[0044] When the culture tank 5 reciprocates and shakes the culture medium, the uniformly distributed and symmetrical stirring rods 11 fixedly installed on the vertical rod 10 also move passively accordingly, stirring the microorganisms. Since the stirring rods 11 are stirred passively, it can further avoid excessive shearing of the microorganisms;

[0045] A control display is provided on the base 1. The display is electrically connected to key components such as the test chamber 2, the optical monitor 8, and the motor 91. Through the control display, the operator can conveniently set test parameters, start or stop the test process, monitor test data, etc.;

[0046] This test device for the stability of the polymer in the culture medium can not only drive multiple culture tanks 5 to pass through the optical region for monitoring respectively to ensure the integrity of the collection of monitoring data, but also avoid excessive shearing of the microorganisms when simulating a dynamic culture medium environment, protect the integrity and physiological activity of the microorganisms, and effectively improve the reliability of the test results.

[0047] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
