Description

Technical Field

[0001] This utility model belongs to the field of water quality sample collection technology, specifically relating to an automatic water quality sample collection device. Background Technology

[0002] Water sample collection refers to the technical process of obtaining representative samples from water bodies such as surface water, groundwater, or sewage according to standardized procedures. Its core objective is to ensure that the physical, chemical, and biological characteristics of water samples remain in their original state before analysis by scientifically selecting sampling sites, using sampling equipment in a standardized manner, and cooperating with appropriate preservation and transportation methods, thereby providing accurate information for water quality assessment, pollution monitoring, and management decisions.

[0003] Currently, water sample collection typically involves manual sampling, such as the water quality sample collection device described in announcement number CN221925735U. This technical solution, through manual sampling, can accurately locate the water layer for precise water sample collection, preventing contact with other water layers. However, this solution still requires manual operation. For flowing rivers, continuous sampling at different times throughout the day is necessary to analyze the changes in water quality throughout the day. This manual collection method is costly and cannot guarantee accurate sampling. Utility Model Content

The present invention provides a technical solution: an automatic water sample collection device, comprising: a collection base 1, a sample storage structure installed on the upper wall of the collection base 1, a protective structure installed on the upper wall of the collection base 1, and the protective structure covering the outside of the sample storage structure; a collection power structure installed on the upper wall of the collection base 1, a filter structure installed at the tail of the collection power structure, and a buoyancy structure installed at the tail of the collection power structure; the sample storage structure comprises: an electrically controlled rotating platform 2, a sample support 3, several sample seats 4, and several sample bottles 5; the electrically controlled rotating platform 2 is installed on the upper wall of the collection base 1, the sample support 3 is installed on the upper wall of the electrically controlled rotating platform 2, and the sample support 3 has several holes; several sample seats 4 are respectively installed on the lower wall of the sample support 3, and the holes of the sample seats 4 and the sample support 3 are aligned; several sample bottles 5 are respectively movably installed in the holes of the sample support 3, and the several sample bottles 5 are respectively located on the upper wall of the sample seats 4.

[0013] As a preferred embodiment, the protective structure further includes: a protective cover 6, two slide rails 7, and a sliding door 8; the protective cover 6 is installed on the upper wall of the acquisition base 1, the side wall of the protective cover 6 is provided with a clearance door, the two slide rails 7 are respectively installed on the side wall of the protective cover 6, the sliding door 8 is movably installed inside the two slide rails 7, and the upper wall of the protective cover 6 is provided with mounting holes.

[0014] As a preferred embodiment, the acquisition power structure further includes: an acquisition power pump 9, an outlet pipe 10, and an inlet pipe 11; the acquisition power pump 9 is installed on the upper wall of the acquisition base 1, one end of the outlet pipe 10 is installed at the outlet of the acquisition power pump 9, and the other end of the outlet pipe 10 is installed in the mounting hole of the protective cover 6, and the other end of the outlet pipe 10 is aligned with the sample bottle 5, one end of the inlet pipe 11 is installed at the inlet of the acquisition power pump 9, and a guide tube 17 is installed at the tail of the outlet pipe 10.

[0015] As a preferred embodiment, the filter structure further includes a filter fixing tube 12 and a filter head 13; the filter fixing tube 12 is fixedly installed at the tail end of the inlet pipe 11, and the filter head 13 is movably installed on the outside of the filter fixing tube 12 by means of threads.

[0016] As a preferred embodiment, the buoyancy structure further includes: a buoyancy rope 14, a buoyancy sleeve 15, and a buoyancy foam 16; one end of the buoyancy rope 14 is installed on the outer wall of the filter fixing tube 12, the buoyancy sleeve 15 is installed on the other end of the buoyancy rope 14, and the buoyancy foam 16 is installed inside the buoyancy sleeve 15.

[0017] Working principle: When using this device, the operator installs the collection base 1 on the shore where water samples need to be collected, and connects the external AC power supply to the device to provide power for the electrical appliances in the device. The matching controller is also installed in the device to provide control and working logic for the electrical appliances in the device.

[0018] Then, depending on the depth of the water area, the operator installs buoyancy foam 16 with different buoyancy levels. If it is necessary to collect samples from the bottom, the operator directly places the filter fixing tube 12 and filter head 13 into the water area. Under the action of gravity, the filter fixing tube 12 and filter head 13 will sink to the bottom. The inlet pipe 11 extends along the bottom of the water area towards the shore. If it is necessary to collect samples from the middle layer of the water area, the operator installs buoyancy foam 16 with the corresponding buoyancy into the buoyancy sleeve 15. Under the pull of the buoyancy foam 16 and the buoyancy sleeve 15, the filter fixing tube 12 and filter head 13 are located in the middle layer of the water area.

[0019] The operator will set the controller to make the sampling power pump 9 work at regular intervals to collect samples every once in a while. During the collection, the electrically controlled rotating table 2 starts to rotate, which drives the sample holder 3 and several sample seats 4 to rotate at a certain angle, so that the new sample bottle 5 is located below the guide tube 17. At this time, the sampling power pump 9 starts to work, and the sample from the target water area enters the inlet pipe 11 through the filter head 13. Through the sampling power pump 9, the outlet pipe 10 and the guide tube 17, the sample flows into the sample bottle 5. When the sample bottle 5 is two-thirds full, the sampling power pump 9 stops working and waits for the next preset time to collect the next water area sample.

[0020] When all sample bottles 5 are full, the controller will stop working. The operator will slide the sliding door 8 between the two slide rails 7 to open the sliding door 8. Then the operator will take out all the sample bottles 5 that are full of samples, install the new sample bottles 5 into the sample holder 3, and restart the device to carry out the next time period of automatic sample collection.
