[0040] The water intake assembly includes a telescopic cylinder 6, a fixing frame 8, a water pump 27 and a water absorption block 12. The telescopic cylinder 6 and the water pump 27 are both fixed to the upper end of the bottom plate 1. The output end of the telescopic cylinder 6 is provided with a positioning frame 7 fixed to the fixing frame 8. A first motor 9 is fixedly arranged at one end of the fixing frame 8. A winding shaft 10 is arranged at the output end of the first motor 9. A pull rope 11 is wound around the winding shaft 10. A water absorption block 12 is arranged at the bottom end of the pull rope 11. A plurality of water absorption holes 14 are arranged on the peripheral side of the water absorption block 12. The water absorption block 12 is connected to the input end of the water pump 27 through a first rubber hose. The output end of the water pump 27 can pump water into the telescopic cylinder 6 through a second rubber hose.

[0041] An analysis method of a water quality detection device requires the use of the above-mentioned water quality detection device, and comprises the following steps:

[0042] Step 1: Place the base plate 1 next to the water source to be tested, and support the base plate 1 through multiple supporting components;

[0043] Step 2: Start the telescopic cylinder 6 to move the reel 10 to the specified position. Start the telescopic cylinder 6 to enable the positioning frame 7 to drive the fixing frame 8 to move to the specified position, and then enable the water absorbing block 12 to move to the specified water surface position;

[0044] Step 3: Start the first motor 9 to unwind the pull rope 11 with the reel 10, so that the water absorbent block 12 descends into the specified water layer. The pull rope 11 has a scale value, and the descending depth of the water absorbent block 12 can be intuitively understood according to the scale value, which is convenient for sampling the water quality of different water layers, and has low limitations during use;

[0045] Step 4: Start the water pump 27. At this time, the water absorption block 12 can pump the water source to be tested from the top tank 16 into the receiving trough 20 through the hose;

[0046] Step 5: Start the second motor 18 to make the stirring shaft 22 stir the water in the docking tank 20;

[0047] Step 6: The water quality in the receiving trough 20 is detected and analyzed by the water quality detection probe in the receiving trough 20. Here, the number of water quality detection probes is not specified, and it can use a variety of probes, for example:

[0048] pH probe: Use a glass electrode to measure the acidity and alkalinity in water. When the glass electrode contacts the water, the hydrogen ions in the water molecules will exchange with the hydrogen ions on the glass electrode, causing a change in potential. By measuring the change in potential, the pH value of the water can be determined;

[0049] Temperature probe: Use a thermistor or thermocouple to measure the temperature of water. When the temperature probe comes into contact with the water, the material inside the probe is affected by the water temperature, and the resistance or potential changes, thereby measuring the temperature of the water.

[0050] Dissolved oxygen probe: Uses a diaphragm and electrodes to measure the dissolved oxygen concentration in water. The special material on the diaphragm allows dissolved oxygen to pass through, while preventing other gases from entering. When dissolved oxygen in the water enters the probe, the potential on the electrode changes, and the dissolved oxygen concentration can be calculated by measuring the potential change;

[0051] Turbidity probe: Uses the principle of light scattering to measure the concentration of suspended particles in water. The probe emits a light beam to illuminate the water and measures the intensity of the scattered light. The photosensitive element in the turbidity probe receives the scattered light and converts it into an electrical signal. The signal strength is proportional to the concentration of suspended matter in the water.

[0052] Step 7: Open the valve on the drain pipe to drain the water in the receiving tank 20 after testing.

[0053] To sum up, this structure can be used for testing in the laboratory and for sampling and testing at any time. It has few limitations when used and has its own stirring function, which can improve the accuracy of water quality testing. It does not require manual sampling, has high sampling efficiency and a high degree of automation, and is convenient for sampling multiple water layers separately.

[0054] In this structure, the support assembly also includes a top seat 4 and a first screw 5.

Through the action of the threaded structure, the support seat 2 can be raised and lowered at the four corners of the bottom plate 1, and the bottom plate 1 can be stably placed on an uneven ground. When the concave and convex part of the placement surface is too large, it is necessary to temporarily rotate the base 3. On the basis of adjusting the support seat 2, continue to adjust the base 3 to increase the adjustment range of the support seat 2.

[0055] In this structure, a counterweight block 13 is fixedly arranged at the lower end of the water absorption block 12, and a third screw is provided at the top end of the counterweight block 13 which is inserted into the bottom of the water absorption hole 14.

The structure is simple, the operation is convenient, and the counterweight block 13 can be easily assembled.

[0056] If there are too many impurities in the water, the accuracy of the water quality during detection will be reduced.

In order to avoid attachment The lines in the figure are too messy, and the first rubber hose and the second rubber hose are not drawn in the attached figure. Since rubber hoses are very common in life, there is no need to describe them in detail here. After the water to be tested enters the top tank 16, it will be filtered by the filter cartridge 17, and the filtered impurities will be stored in the filter cartridge 17, thereby providing a filtering effect for the impurities in the water quality, which can improve the accuracy of water quality during detection. When the filter cartridge 17 needs to be cleaned, the top cover 15 can be removed from the top tank 16. Through the cooperation of the card block and the card slot, the filter cartridge 17 can be placed more firmly on the limit seat 23.
