Description

Technical Field

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

[0002] Water quality testing is a core technology in environmental protection, water resource management, drinking water safety assurance, and industrial production process monitoring. The accuracy of its test results directly affects the scientific nature of ecological environment governance decisions, the safety of drinking water, and the quality stability of industrial products. Current water quality testing technologies generally use water quality analyzers. These analyzers typically use a probe as the core sensing component. This probe integrates sensing elements for one or more water quality parameters, such as pH, dissolved oxygen, conductivity, and turbidity. By immersing the probe in the water body to be tested, the sensing elements come into direct contact with the water and undergo physical or chemical reactions, converting the water quality parameters into collectable electrical signals. These signals are then processed by a signal processing module to convert them into intuitive numerical information, enabling quantitative detection of water quality parameters.

[0003] In the process of testing groundwater, drilling is usually carried out first, and then a testing probe is lowered into the water source through the borehole using a rope. However, during the process of the testing probe penetrating the borehole, the testing probe is prone to collision with the side wall of the borehole. During the collision, soil can easily adhere to the surface of the testing probe, and the testing probe is easily damaged due to the collision, which in turn affects the testing accuracy of the testing probe.

On the support frame 2, a lifting mechanism for driving the positioning ring 13 to move up and down includes a positioning cover 14, an electric push rod 15, and a guide rod 16. The positioning cover 14 is fixedly installed on the top side wall of the support frame 2, and the support opening 3 passes through the positioning cover 14. The positioning ring 13 is located inside the positioning cover 14 and is slidably connected to the inner wall of the positioning cover 14.

Specifically, the operation of the second motor 20 can drive the second pulley 19 to rotate. At the same time, the belt drives the first pulley 18 and the positioning wheel 10 to rotate. Then, the friction between the positioning wheel 10 and the support column 4 drives the support column 4 to move, thereby facilitating the adjustment of the position of the detection probe 5. At the same time, the support column 4 can limit the detection probe 5, thereby preventing the detection probe 5 from colliding with the borehole sidewall. The first motor and the second motor 20 can be powered by cables.

[0028] Working principle: In use, the operator first drills a hole in the ground down to the water source. Then, the operator places the support frame 2 on the ground and aligns the support opening 3 with the drilled hole. Next, the positioning cone 22 is used to position the ground and the support frame 2. Then, the operator inserts the support column 4 through the support opening 3 and controls the electric push rod 15. The operation of the electric push rod 15 moves the positioning ring 13, the adjusting block 11, and the first rack 12. Simultaneously, the meshing of the first rack 12 with the first gear 8 drives the first gear 8 to rotate, which in turn drives the positioning block 9. The angle is adjusted and the positioning wheel 10 is pressed against the surface of the support column 4, thereby cooperating with the support port 3 to achieve positioning and clamping of the support tube. Then, the operator controls the second motor 20 to work. The operation of the second motor 20 can drive the second pulley 19 to rotate. At the same time, the belt drives the first pulley 18 and the positioning wheel 10 to rotate. Then, the friction between the positioning wheel 10 and the support column 4 drives the support column 4 to move, thereby facilitating the adjustment of the position of the detection probe 5 and extending the detection probe 5 into the water source. Then, the water source can be tested by the water quality tester 1.
