Description

Technical Field

[0001] The utility model relates to the technical field of hydrological sampling, and in particular to a sample collection storage device. Background Art

[0002] Hydrogeological survey refers to the discontinuous or continuous extraction of a representative portion from a specific water body, and the water samples are sent to the testing room according to the requirements of the project being tested. However, after the hydrological sampling is taken and stored, it is impossible to automatically monitor the storage time of the samples. This is because the storage time of some water samples varies from project to project. Unlike traditional water sample testing methods, the samples have a long storage time, and they need to be tested in a short time to ensure the accuracy of the test data. For example, the sulfuric acid system is used for the study of comprehensive pollution indicators such as trinitrogen conversion, reducing substances, and organic matter in groundwater. It is required to add sulfuric acid after collecting the sample and refrigerate it for 24 hours to complete the test. When the staff forgets to take the water sample, resulting in the water sample storage time about to expire, the staff cannot be reminded in a timely manner. As a result, when the water sample is taken later, the water sample has exceeded the maximum storage time and cannot be used for testing, resulting in waste. Utility Model Content

The refrigerated opening and closing switches are touch switches, and the button end of the refrigerated opening and closing switches faces the upper side. When the refrigerated opening and closing switch is in a non-pressed start state, the button end of the refrigerated opening and closing switch protrudes from the pressing groove; when the bottom end surface of the box cover is in contact with the top surface of the box, the bottom end surface of the box cover presses against the button end of the refrigerated opening and closing switch, and at this time the refrigerated opening and closing switch is in a pressed start state.

[0007] Furthermore, it also includes six groups of preservation monitoring units, which are composed of a warning light, a timing start and close switch and a timing module; the warning light is fixedly installed on the top surface of the box body adjacent to the top open end of the plug-in hole, and the warning light is electrically connected to the microcontroller; the timing start and close switch is fixedly installed on the bottom surface of the inner end of the annular matching groove, and the timing start and close switch adopts a touch switch, the button end of the timing start and close switch faces the upper side, and the timing start and close switch is electrically connected to the microcontroller; the timing module is installed inside the box body, and the timing value of the timing module is not limited, and it is set according to the preservation time of the sample, and the timing module is electrically connected to the microcontroller.

[0008] Furthermore, when the spring is in a natural state, the bottom end surface of the annular slider does not contact the button end of the timing on / off switch; a buzzer electrically connected to the microcontroller is also installed on the side end surface of the box body; when the timing on / off switch is in a pressed start state, the timing on / off switch feedback signal is given to the microcontroller, and the microcontroller controls the timing module to start; when the timing value of the timing module is reached, the timing module feedback signal is given to the microcontroller, and the microcontroller controls the buzzer to start, and controls the corresponding warning light to start.

[0025] In this embodiment, six groups of storage monitoring units are also included, and the storage monitoring units are composed of a warning light 01, a timing start and close switch 02 and a timing module 03; the warning light 01 is fixedly installed on the top surface of the box body 1 adjacent to the top open end of the plug-in hole 1013, and the warning light 01 is electrically connected to the microcontroller 1021; the timing start and close switch 02 is fixedly installed on the bottom surface of the inner end of the annular matching groove 1014, and the timing start and close switch 02 adopts a touch switch, and the button end of the timing start and close switch 02 faces the upper side, and the timing start and close switch 02 is electrically connected to the microcontroller 1021; the timing module 03 is installed inside the box body 1, and the timing value of the timing module 03 is not limited, and it is based on the storage time of the sample.

[0026] The working principle of this embodiment is as follows:

[0027] After the staff takes the hydrological sample, they store the sample in the sample storage tube, and then align the sample storage tube with a plug-in hole 1013 and insert it, so that the rubber sleeve a108 can clamp the sample storage tube to achieve the limit fixation of the sample storage tube. Then the staff rotates and closes the box cover 102, and the box cover 102 in the closed state is limited and fixed by the engagement of the fastener 103 with the fastener groove 101. When the box cover 102 is in the closed state, the bottom end surface of the box cover 102 presses against the button end of the refrigeration opening and closing switch 1019. At this time, the refrigeration on-off switch 1019 is in a pressed start state, and the refrigeration on-off switch 1019 feedback signal is given to the microcontroller 1021, and the microcontroller 1021 controls the semiconductor refrigeration plate 1010 to start. The cold air generated by the refrigeration end of the semiconductor refrigeration plate 1010 is transmitted to the plug hole 1013 through the refrigeration cavity 1012, thereby realizing low-temperature preservation of the sample in the sample storage tube. The temperature sensor 1011 senses the temperature and realizes temperature control to ensure that the temperature is maintained at a suitable refrigeration temperature state.

[0028] When the sample storage tube is inserted into the insertion hole 1013, the sample storage tube will be synchronously inserted into the rubber sleeve b1016 of the annular slider 1015, and the annular slider 1015 and the sample storage tube will be temporarily integrated through the rubber sleeve b1016. At this time, when the sample storage tube moves downward, the annular slider 1015 will be synchronously driven to move downward along the annular matching groove 1014, so that the bottom end surface of the annular slider 1015 presses against the button end of the timing start and close switch 02. At this time, the timing start and close switch 02 is in a pressed start state, and the timing start and close switch 02 feedback signal is given to the microcontroller 1021. The microcontroller 1021 controls the timing module 03 to start. The timing value of the timing module 03 can be determined according to the storage time of the sample. For example, if the time is twenty-four hours, the timing value of the timing module 03 can be set to twenty-three hours, and one hour is reserved. With this design, when the staff forgets to take the sample, resulting in the sample storage time being about to expire, when the timing value of the timing module 03 is reached, the timing module 03 feedbacks a signal to the microcontroller 1021, and the microcontroller 1021 controls the buzzer 107 to start buzzing. The high-decibel buzzing of the buzzer 107 is used to remind the staff, and the corresponding warning light 01 is also controlled to start, which is beneficial for the staff to open the box cover 102 through the high-decibel buzzing of the buzzer 107. When the staff is reminded by the high-decibel buzzing of the buzzer 107, they can observe that the warning light 01 at that location is lit, thereby knowing that the current group of samples is about to expire.
