[0001] The utility model relates to the technical field of water quality detection equipment, in particular to a portable multi-index multi-point sampling water quality detector. Background Art

[0002] The existing water quality testing modes generally include laboratory testing and outdoor testing. Laboratory testing has better results and more testing items, but it has higher requirements for the laboratory environment and equipment; outdoor testing has lower costs and is convenient and fast, but it is difficult to use reagent testing methods and has fewer testing items.

Some areas are unable to establish relatively complete laboratories, and the existing portable water quality testers cannot meet the various testing indicators of national standards. In addition, water sources in inland areas migrate frequently, making it difficult to test water sources in multiple places at the same time, which is also an urgent problem to be solved.

[0043] An opening slider 2 is provided above the rotatable pressing cover 1, which can be slid open to add water sample into the water sample tube 9, and can be slid closed to seal the water sample tube 9;

[0044] The water sample tubes 9 are used to store water samples, and there are six of them, which are located directly below the rotatable pressing cover 1; the water sample tubes 9 are long cylinders without tops, and a water sample tube one-way valve 12 is provided below;

[0045] The water sample tube support 10 is arranged directly below the rotatable pressing cover 1 and is used to fix the water sample tube 9; the outer diameter of the water sample tube support 10 is smaller than the diameter of the cylinder 6, and the inner diameter of the water sample tube support 10 is larger than the diameter of the water sample tube 9;

[0046] The water sample is made to flow down to a reaction detection device, comprising:

[0047] The probe detection tray 5 is located directly below the water sample tube 9. A water sample probe detection screen 15 is provided on the front of the probe detection tray 5, which can be used to view some items detected by the probe;

[0048] The cylinder 6 also includes:

[0050] The detachable folding bracket 8 is located below the cylinder 6 and can be placed in various complex environments and terrains.

[0051] Specifically, Figure 2 As shown, it is a schematic diagram of the structure of the fixing device of the water sample tube 9 of the utility model. The water sample tube 9 is placed on the water sample tube holder 10, and the water sample tube holder 10 is fixed by the step groove on the inner wall of the cylinder 6; when the water sample tube 9 needs to be replaced and cleaned as a whole, the water sample tube holder handle 11 is carried by hand so that six water sample tubes 9 can be taken out at the same time.

[0052] Specifically, Figure 1 and Figure 3 As shown, it is a schematic diagram of the structure of the detachable water sample probe reagent tray of the utility model. A reagent tray slide rail 16 corresponding to the probe detection tray is provided on the cylinder 6, and the probe detection tray 5 can be pushed into the correct position along the reagent tray slide rail 16.

[0059] Specifically, the portable multi-indicator multi-point sampling water quality detector of the utility model also includes a series of water sample detection probes 14 of different solute types. The water sample detection probes 14 can be placed on the probe reagent tray. The water sample detection probes 14 are raised by the lifting and adjusting mechanism 4.

After being released, under the action of water pressure and the spring, the sealing end plate moves downward to seal the water sample tube, and the water sample no longer flows out.

[0063] In this embodiment, the side of the lifting adjustment mechanism 4 is marked with scale lines, and when adjusting the lifting adjustment mechanism 4 to control the quantitative outflow of the water sample, the height of the reagent disk movement and the amount of water flowing out can be easily observed;

[0064] In the embodiment, the rotating part of the mechanical timer 7 is provided with anti-skid material to increase the friction between the timer shaft and the user's hand, and prevent the timer surface from being slippery and difficult to rotate, resulting in large timing errors;
