Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and more specifically, to a water quality sampling and multi-parameter testing device. Background Technology

[0002] Water is the source of life and an indispensable basic resource for human survival and development. Whether it's water for daily life, industrial production, or agricultural irrigation, its quality directly affects human health, the quality of industrial products, and the yield and quality of crops. Water quality testing is necessary to determine whether water meets standards.

[0003] A search revealed that patent application CN202221473625.6 discloses a user-friendly sampling device for water quality testing. The device includes a main body and a control box. The control box is mounted on the upper outer side of the main body, with a display screen embedded in its panel. Below the display screen are operation buttons, and a power switch is located beside the operation buttons. A sampling connector is located on one side of the main body, connected to a sampling hose. A sampling head is installed at the end of the sampling hose. This utility model integrates sampling and testing functions, allowing for direct testing after sampling. The test results are highly accurate. Its trolley case design makes it easy to carry. The sampling hoses on the main body are available in different lengths to meet sampling needs in various geographical environments. It offers good safety and practicality. However, it still has the following drawbacks: (1) In the prior art, sampling hoses and sampling heads are used to sample water quality. The sampling range of water quality is small. When sampling large areas of water, the sampling personnel need to move the sampling device frequently. The operation process is cumbersome, resulting in low sampling efficiency and difficulty in meeting large-scale requirements. At the same time, blockage is also likely to occur during sampling. Existing technologies use a single detection head to test water quality, resulting in fewer test items, less comprehensive water quality parameters, and poor practicality.

[0004] Therefore, we have made improvements to this and proposed a water quality sampling and multi-parameter detection device. Utility Model Content

[0023] Specifically, when using this water quality sampling and multi-parameter detection device: First, take the drone 3 out of drawer 2 and control it to take off using the remote control. The drone 3 will fly to the sampling point. Upon arrival, motor 903 drives the drive gear 904 to rotate. The rotation of the drive gear 904 drives the driven gear 901 to rotate, which in turn drives the solid tube 6 to rotate, thus allowing the sampling tube 8 to rotate into a vertical position. Then, control the drone 3 to descend and insert the filter cartridge 10 and filter screen 11 into the water. Next, start the micro pump 12 to draw water from the sampling tube 8 through the first connecting pipe 13 and the second connecting pipe 14. The sampled water is then stored... The water is stored in storage cylinder 16. After sampling, the drone 3 is controlled to return to base and remove storage cylinder 16. The water in storage cylinder 16 is poured into test tubes 2403. Then, test tubes 2403 are placed in insert plates 2401. The electric telescopic rod 2402 drives the test tubes 2403 to move upward, so that turbidity sensor 21, dissolved oxygen sensor 22 and pH sensor 23 can be inserted into test tubes 2403. Turbidity sensor 21 detects the turbidity of the water sample, dissolved oxygen sensor 22 detects the dissolved oxygen content in the water sample, and pH sensor 23 detects the pH of the water sample. The multi-parameter detection results of the water sample are displayed on display screen 18.
