example 1
In this embodiment, the temperature in the safety cabinet needs to be detected, so as to ensure the cultivation environment of microorganisms in the safety cabinet;
in the present embodiment, the initial position of the electric telescopic rod 7 is in a contracted state, so that the temperature sensor 12 on the long plate 8 is positioned below the storage cavity 9;
specifically, a worker puts microorganisms to be cultivated into a test tube, slides the sliding door 2 upwards, opens the safety cabinet, inserts the test tube into the storage barrel 5 in the storage box 4, closes the sliding door 2 after the test tube is placed, and inputs the adaptive temperature range of the stored microorganisms on the controller 3, wherein the adaptive temperature range is set according to the stored microorganisms;
when the electric telescopic rod 7 is at the initial position, detecting the air temperature below the storage cavity 9, transmitting a signal to the controller 3 by the temperature sensor 12, recording the signal, controlling the electric telescopic rod 7 to extend by the controller 3 to drive the long plate 8 to move upwards, and when the stroke of the electric telescopic rod 7 is finished, bringing the long plate 8 above the storage cavity 9, detecting the air temperature above the storage cavity 9 by the temperature sensor 12, transmitting the signal to the controller, recording the signal, detecting a wider range in a safety cabinet in which air does not circulate, and well judging the condition of the air environment inside the safety cabinet;
comparing the detected temperature in the storage cavity 9 with a set temperature range, and if the detected temperature is in the set temperature range, indicating that the air environment in the storage cavity 9 is a high-quality environment, and being suitable for microorganism cultivation; if the temperature in the storage chamber 9 exceeds the set range during the moving process of the long plate, the air environment in the storage chamber 9 needs to be adjusted, wherein the detecting and adjusting methods are as follows:
s1, if the temperature above the storage cavity 9 is higher than the preset temperature or lower than the preset temperature, and the temperature below the storage cavity 9 is detected to be within a set range, the controller 3 controls the fan 19 above the storage cavity 9 to slowly rotate so that the air with high temperature above the storage cavity 9 flows and can be fused with the air below the storage cavity 9, if the temperature below the storage cavity 9 is higher than the preset temperature or lower than the preset temperature, and the temperature above the storage cavity 9 is detected to be within the set range, the controller 3 controls the fan 19 below the storage cavity 9 to slowly rotate so that the air with high temperature below the storage cavity 9 flows and is fused with the air above the storage cavity 9, and the air in the storage cavity 9 reaches a proper state of microorganisms through ventilation air;
s2, when the upper temperature and the lower temperature are detected in the storage cavity 9 and are not in the set range, the fact that the whole air in the storage cavity 9 is not suitable for microbial cultivation survival is indicated, so that the controller 3 transmits a signal to the alarm to remind personnel that the temperature in the safety cabinet is not suitable for microbial growth;
s1 comprises the following specific operation steps:
s11, after the fan 19 runs for a period of time, the controller 3 controls the fan to stop, the air in the storage cavity 9 is kept still for a period of time, the electric telescopic rod 7 is controlled to move up and down in the storage cavity 9 again, the temperatures of the air above and the air below the storage cavity 9 are detected, and if the temperatures above and below are in a proper range, the air in the storage cavity 9 reaches a proper state of microorganisms; the signal is transmitted to the temperature controller 10, so that the temperature controller 10 controls the temperature in the storage cavity 9 to be reduced to a temperature to which microorganisms can adapt, and if the temperature is lower than the lowest temperature of the preset temperature by one degree centigrade, the temperature in the storage cavity 9 is controlled to be increased in the same way, so that the internal temperature balance can be ensured;
s12, if the temperatures above and below the storage cavity 9 are detected to be not in a proper range again and the temperature difference between the temperature and the preset temperature is within one degree centigrade, the controller 3 controls the temperature controller 10 to start, the temperature in the storage cavity 9 is adjusted, the temperature in the storage cavity 9 is detected through the temperature sensor 12, and when the internal temperature reaches the preset temperature, the controller 3 controls the temperature controller 10 to pause, so that the air in the storage cavity 9 reaches a state suitable for microorganisms;
s13, when the temperature difference between the temperature in the storage cavity 9 and the preset temperature is detected to be more than one degree centigrade again after the step S1, the controller 3 transmits a signal to the alarm, so that the alarm and the alarm can give an alarm to remind people that the temperature in the safety cabinet is not suitable for microorganism growth and timely processing;
example two

the outside of the cabinet body 1 is fixed with a temperature detector 6 for detecting the air temperature outside the cabinet body 1, and the temperature detector 6 is electrically connected with the controller 3;
when a worker needs to observe microorganisms at a short distance, the worker needs to move the sliding door 2, and lean into the storage cavity 9 to observe conveniently, and as the temperature in the storage cavity 9 is a specific range, the condition of the air temperature outside the cabinet body 1 needs to be detected in real time, so that the temperature outside the cabinet body 1 is prevented from influencing the temperature stored by the microorganisms when the sliding door 2 is opened;
the temperature difference grade between the temperature outside the cabinet body 1 and the temperature in the storage cavity 9 is set to be low and high by staff in the controller 3, wherein the low grade is the temperature difference which indicates that the temperature outside the cabinet body 1 and the temperature in the storage cavity 9 are small, and the high grade is the temperature difference between the inside and the outside;
specifically, the temperature sensor 6 detects the temperature outside the cabinet body 1, transmits a signal to the controller 3, compares the temperature with the temperature in the storage cavity 9, and can open the sliding door 2 to closely observe microorganisms in the test tube without protection work because the temperature in the storage cavity 9 is in a preset temperature range if the temperature difference between the outside of the cabinet body 1 and the temperature in the storage cavity 9 corresponds to the preset low level of a worker, and the temperature difference between the inside and the outside is proved to be small, so that the influence on the internal temperature is not caused after the air outside the cabinet body 1 and the air in the storage cavity 9 interact;
when the temperature difference between the outside of the cabinet body 1 and the temperature in the storage cavity 9 corresponds to the preset advanced level of a worker, the temperature difference between the inside and the outside is large, so that the worker can open the sliding door 2, when the worker opens the sliding door 2, the controller 3 transmits a signal to the first drive 15 to rotate for one hundred eighty degrees to drive the supporting table 11 to rotate, so as to drive the cleaning bar 13 to downwards, then the electric telescopic rod 7 is controlled to shrink, the long plate 8 is driven to downwards move, the supporting table 11 drives the cleaning bar 13 to downwards move, the cleaning bar 13 is wrapped outside the storage barrel 5, and the storage environment in the storage cavity 9 is influenced due to interaction of the inside and the outside air, so that the supporting table 11 is controlled to descend, the storage box 4 is covered, and the outside temperature is prevented from influencing microorganisms in a test tube;
after the sliding door 2 is completely opened, the supporting plate 11 is already covered above the storage box 4, and as the supporting plate 11 is made of transparent materials, workers can see the state of microorganisms in the test tube through the surface of the supporting plate 11, and the supporting plate 11 can isolate the outside air;
after the observation of the staff is finished, the sliding door 2 is pulled down, and because the sliding door 2 is internally and externally provided with air interaction when being opened, the air in the storage cavity 9 is influenced, therefore, when the sliding door 2 is closed, the temperature in the storage cavity 9 is detected through the temperature sensor 12, signals are transmitted to the controller 3 to be compared with a preset temperature range, if the temperature in the storage cavity 9 is detected to be medium in temperature difference with the preset temperature, the step S1 is repeated, the air temperature in the storage cavity 9 is enabled to be in a proper state, and when the temperature in the storage cavity 9 is detected to be high in temperature difference with the preset temperature, the signals are transmitted to the alarm in the controller 3 to be alarmed, and the signals are processed by the staff;
when the air temperature in the storage cavity 9 reaches a proper state, a signal is transmitted to the controller 3, the controller 3 controls the electric telescopic rod 7 to extend to drive the cleaning strip 13 to move upwards, and the surface of the test tube is wiped when the cleaning strip 13 moves, so that dust is wiped, and the cleanliness of the microorganism storage environment is improved;
through the steps, when a worker finishes taking the test tube, the supporting plate 11 covers the storage box 4, so that the outside temperature is prevented from affecting microorganisms in the test tube, and meanwhile, when the sliding door 2 is closed, the temperature in the storage cavity 9 is controlled to be in a proper state, and meanwhile, dust on the test tube can be erased.
