Description

Technical Field

[0001] The present invention relates to the technical field of sample storage, and in particular to a movable sampling storage device dedicated to waterfowl experiments. Background Art

[0002] In waterfowl farming and waterfowl disease monitoring and other related research fields, on-site biological samples are complex and diverse, including but not limited to blood, tissue, and fecal samples. Depending on the specific test indicators, samples need to be classified and stored on-site. For example, if DNA molecular functional identification is required, samples need to be stored in a cryogenic freezer at -20°C; if RNA, protein, intestinal flora testing is required, they need to be stored at an ultra-low temperature of -80°C or quickly frozen in liquid nitrogen at -196°C; if physiological and biochemical indicators, enzyme activity, and other indicators in tissue or blood are to be tested, they must be refrigerated at 4°C.

[0003] Standardized sample storage is a key step in ensuring the reliability of test data. Traditional sampling operation modes have significant technical flaws: researchers usually use simple foam boxes with crushed ice, dry ice, or liquid nitrogen on site to meet sample storage needs. This can only meet the short-term sampling needs of a single barn. When sampling from different barns or on a large scale, repeated transportation and addition of refrigeration materials are required. After collection, the samples are placed haphazardly and subsequently need to be manually sorted, sorted, and placed in refrigerators (4°C), ultra-low temperature freezers (-20°C or -80°C), or liquid nitrogen tanks (-196°C). This traditional method is not only prone to sample degradation or contamination during collection, storage, and transportation, affecting the accuracy and consistency of test results, but also leads to low work efficiency during sample sorting and equipment switching, consuming a lot of time and manpower, and is not suitable for large-scale sampling. Summary of the Invention

[0035] The remaining structures are the same as those of Example 1.

[0036] Example 3, reference Figure 1 - Figure 10, which is the third embodiment of the present invention, which is different from the second embodiment in that: the driving component 301 includes a second motor 3011 provided on the cart body 101, a driving rotating rod 3013 provided at the output end of the second motor 3011, a fixed plate 3014 rotatably provided on the driving rotating rod 3013, and an auxiliary rotating rod 3015 rotatably provided at the other end of the fixed plate 3014, a moving track 3016 is provided on the cart body 101, a moving member 3017 is slidably provided on the outer diameter of the moving track 3016, a rotating shaft 3018 is rotatably provided at the front end of the moving member 3017, and the rotating shaft 3018 is fixedly connected to the storage component 302 , a limit member 3019 is provided at one end of the moving member 3017, and the limit member 3019 is slidably connected to the driving rotating rod 3013. Linkage rods 3012 are rotatably provided on both sides of the moving member 3017. The storage assembly 302 includes a storage box 3021 provided on the rotating shaft 3018, and a conical block 3022 provided at the bottom of the storage box 3021. When the sample test tube is transported to the inside of the guide member 2016 through the sorting assembly 201, the motor 2 3011 also drives the rotating rod 3013 to rotate, so that the limit member 3019 sliding inside the driving rotating rod 3013 brings the moving member 3017 and the storage assembly 302 along the moving track 3 016 rotates and moves, and with the cooperation of multiple limit members 3019, the linkage rods 3012 between the moving members 3017 push each other, so that the rotating shaft 3018 on the moving member 3017 can move the storage box 3021 to the bottom of the guide member 2016, and start batch storage of sample test tubes. After the storage of the first storage box 3021 is completed, the motor 2 3011 drives the limit member 3019 to move along the driving rotating rod 3013, thereby moving the next storage box 3021 to the bottom of the guide member 2016 for the storage of the second batch of sample test tubes. Batch storage is performed, and at the same time, the refrigeration equipment 102 also refrigerates the inside of the cart body 101 The sample tubes stored in batches on both sides are cooled at different temperatures to ensure that the sample tubes on both sides of the cart body 101 are stored at the required different temperatures, realizing classified, zoned and batched storage. When sampling, it is only necessary to open the sampling piece 103 to quickly sample the samples on the storage box 3021. At the same time, with the cooperation of the conical block 3022 at the bottom of the storage box 3021, the stability of the storage box 3021 is guaranteed when the storage box 3021 is driven by the motor 2 3011 to move, and the storage box 3021 is adjusted and coordinated under the rotation of the rotating shaft 3018, so that the storage box 3021 can always be kept facing upward, ensuring the safety of the stored sample tubes.

After the storage of the first storage box 3021 is completed, the motor 2 3011 drives the limiting member 3019 to move along the driving rotating rod 3013, thereby putting the next storage box 3021 into the storage box 3021. 1 moves to the bottom of the guide member 2016 to store the second batch of sample tubes, and performs batch storage. At the same time, the refrigeration equipment 102 also cools the sample tubes stored in batches on both sides of the cart body 101 at different temperatures, ensuring that the sample tubes on both sides of the cart body 101 are stored at the required different temperatures, realizing classified, zoned and batch storage, and when sampling, it is only necessary to open the sampling member 103 to quickly sample the samples on the storage box 3021. At the same time, with the cooperation of the conical block 3022 at the bottom of the storage box 3021, the stability of the storage box 3021 is guaranteed when the storage box 3021 is driven by the motor 2 3011 to move, and the storage box 3021 is adjusted and matched under the rotation of the rotating shaft 3018, so that the storage box 3021 can always be kept facing upward, ensuring the safety of the stored sample tubes.

[0039] After quickly sorting and partitioning samples such as waterfowl blood, hair, and feces, if a sample tube that requires liquid nitrogen refrigeration is encountered, the user only needs to open the flip cover 3032 and place the sample tube inside the liquid nitrogen box 3033.
