Description

Technical Field

[0001] The present invention relates to the technical field of mobile laboratories, and more particularly to a mobile DNA laboratory for forensic science. Background Art

[0002] Forensic science DNA laboratories are mainly responsible for individual identification and paternity testing. The main research methods they use involve chemistry, physics, morphology, immunoserology, biochemistry, molecular biology and genetics. In order to ensure the quality of forensic evidence identification and the scientificity and reliability of the identification results, the overall layout of the forensic science DNA laboratory should take into account the potential risk of sample contamination, reduce the impact on the test results and harm to personnel, and each area of ​​the laboratory should be independent and meet the requirements of one-way flow. Equipment and objects in the area should be clearly marked to avoid mixing of special equipment and items in different work areas.

[0003] However, traditional forensic science DNA laboratories can only be located in fixed locations and do not have the capabilities to extend the entire DNA laboratory to the crime scene for on-site testing, rapid comparison, and laboratory management.

[0004] After searching, a Chinese patent with authorization announcement number CN112519656A discloses a mobile DNA laboratory for forensic science. This structure can realize intelligent experiments in forensic science under mobile conditions, and can perform real-time extraction and detection at the scene of the crime. It has the experimental conditions of mobile carrying and field support modules, and is divided into a cab, an amplification sequencing room, an extraction and analysis room, and an equipment area. Each cabin is completely physically isolated. The amplification sequencing room and the extraction and analysis room are convenient for isolation and for personnel to enter and pass through. There is a transfer window of a forensic laboratory between them, which ensures the accuracy of the experiment and avoids infection of the test samples. The rear is an experimental analysis and consultation station. Each room has complete functions and clear division of labor. It is equipped with a purification air conditioner and ventilation system to improve the indoor environment and meet the standards of a secondary biological laboratory. By controlling the wind direction, air volume and air pressure, the requirements of negative pressure in the sequencing room and positive pressure in the extraction room are achieved.

[0005] However, when this structure is actually used, the internal space of the mobile DNA laboratory is limited, and it cannot be equipped with large water storage equipment and a complete water supply system like a fixed laboratory, resulting in a relatively small water storage capacity. Moreover, in some remote areas or special sites, the mobile DNA laboratory vehicle may be far away from conventional water sources such as urban water supply networks and cannot be easily connected to water sources, resulting in insufficient water supply and inability to operate for a long time. Summary of the invention

[0015] Technical effects and advantages of the present invention: 1. By setting up a recycling mechanism, compared with the existing technology, when it rains, the rainwater falling on the inclined top plate on the top of the carriage will slide down the two sides of the inclined top plate into the water guide frame. The inclined coarse filter can initially filter out larger impurities in the rainwater. The rainwater filtered by the coarse filter flows into the water storage tank through the guide pipe at the bottom of the water guide frame for storage, and the water stop valve on the guide pipe can control the water flow, thus achieving efficient diversion of rainwater and preliminary impurity filtration into the water storage tank for storage, ensuring that in rainy weather, the laboratory can effectively collect and store relatively clean rainwater. On the one hand, it can provide water source supplement for some non-critical water use links in the laboratory, and on the other hand, it also reflects the rationality and environmental protection of the laboratory in resource utilization, reducing the degree of dependence on external water supply; 2. By setting up a cleaning mechanism, compared with the existing technology, the partition inside the water tank guides rainwater to be purified through a fine filter and an activated carbon filter plate in turn. Purification agents can also be added through a feeding pipe. The water level can be controlled with the help of an observation port, so that effective rainwater purification and real-time monitoring of water use can be achieved. Water can be pumped out on demand and water resources can be used rationally. When cleaning, the stepper motor is started to drive the rotating rod through the transmission component. The stirring rod on the rotating rod stirs up the precipitated impurities. At the same time, the threaded sleeve drives the cleaning roller to roll along the fine filter to scrape off the attached impurities. The combination of the two can fully clean the water tank and maintain its good performance and normal operation.

[0016] 3. By setting up a cleaning mechanism test bench, sample receiving area, amplification detection area, and data analysis area, compared with the existing technology, various biological samples are collected and preliminary sorting and registration are completed to ensure that the sample information is complete, laying a solid foundation for subsequent DNA testing, and odors and harmful gases can be discharged in time to ensure the health of staff and the normal progress of experiments. The test bench is convenient for amplification and detection experiments, so that staff can perform fine experimental operations at a suitable height and layout to improve work efficiency. At the same time, the work cabinet can be used to store reagents, instruments and other items required for the experiment, which is convenient for staff to use at any time during the experiment without frequent travel to other storage areas, further saving time and energy and ensuring the continuity of experimental operations. At the same time, the conference table and chairs are conducive to staff discussions, exchanges of results and writing reports. BRIEF DESCRIPTION OF THE DRAWINGS
