The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0029] like Figure 1-2 As shown in the figure, this utility model embodiment proposes a surface water sampling and testing device, including a water quality tester 1, a base 2, a collection container 3, a water outlet 6, a clean water tank 4, and a collection hose 5.

[0030] Specifically, the water quality analyzer 1 is mounted on the base 2 via a placement seat 27; a support 7 is mounted on the base 2, and a drive shaft 8 is rotatably mounted on the upper side wall of the support 7, and a flip motor 9 for driving the drive shaft 8 is installed inside the support 7; one end of the collection container 3 is open, and the outer side wall of the collection container 3 is connected to the drive shaft 8; the water tap 6 is mounted on the base 2 via a bracket 10 and is located above the collection container 3, with the outlet end of the water tap 6 facing the collection container 3, and the... The inlet of the water faucet 6 is connected to the first conduit 12 and the second conduit 13 via a three-way pipe 11. A switch valve 14 is installed between the first conduit 12 and the second conduit 13 and the three-way pipe 11. The water tank 4 is installed on the top of the bracket 10, and the bottom of the water tank 4 is connected to the first conduit 12. A float 15 is installed on the outer wall of the collection hose 5. One end of the collection hose 5 is connected to the second conduit 13, and a counterweight 16 is installed on the side wall of the other end of the collection hose 5. A water pump 17 is installed on the second conduit 13.

[0031] In this embodiment, a suitable amount of clean water is pre-filled in the water tank 4. When the surface water sampling and testing device is working, the flip motor 9 is first started so that the opening end of the collection container 3 is directly opposite the outlet end of the water tap 6, and the float 15 is placed at the collection position. Under the buoyancy of the float 15, the collection end of the collection hose 5 is maintained at a certain water depth. Then, the water pump 17 is started and the switch valve 14 connected to the second conduit 13 is opened. Under the action of suction, the surface water is transferred to the collection container 3 through the collection hose 5 and the water tap 6, realizing the surface water collection. Finally, the surface water in the collection container 3 is collected by sampling tools such as droppers and syringes and sent to the detection and receiving area of ​​the water quality analyzer 1 to realize the surface water detection process.

[0032] After the inspection is completed, the flipping motor 9 is restarted, causing the collection container 3 to rotate one full circle, thus removing any residual liquid.
