DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a surface water quality monitoring and sampling device. Figure 1-4, a surface water quality monitoring sampling device, comprising a floating plate 1, one side of the upper end of the floating plate 1 is fixedly connected to a support plate 2, one side of the support plate 2 is slidably connected to a moving plate 5, and one side of the moving plate 5 is fixedly connected to a sampling frame 6, the upper end of the sampling frame 6 is fixedly connected to a stepper motor 7, the output end of the stepper motor 7 is fixedly connected to a rotating rod 8, the rotating rod 8 passes through the inner wall of the sampling frame 6 and is fixedly connected to a first baffle 81 at equal intervals, the first baffle 81 is a fan-shaped plate with an angle of 30°, and six of them are arranged in a circle, the sampling frame 6 is fixedly connected to a second baffle 82 at equal intervals near the first baffle 81, the second baffle 82 is a fan-shaped plate with an angle of 45°, and six of them are arranged in a circle, the stepper motor 7 drives the rotating rod 8 to rotate, so that the rotating rod 8 drives the first baffle 81 to rotate 22.5°, and blocks the gap directly between the second baffle 82 to achieve layered sealing;

[0022] By adopting the above technical solution, the threaded rod 4 is threadedly connected to the movable plate 5, the upper end of the threaded rod 4 is fixedly connected to the servo motor 3, and the servo motor 3 is fixedly connected to one side of the upper end of the support plate 2. The servo motor 3 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the movable plate 5 to descend, and drives the sampling frame 6 to descend, so that the sampling frame 6 descends from the through slot 10 into the water, so that the sampling frame 6 is used to sample the water.

[0023] By adopting the above technical solution, a slide plate 51 is fixedly connected to one side of the movable plate 5, and the slide plate 51 is slidably connected to the support plate 2. The set slide plate 51 can limit the movable plate 5, so that the movement of the movable plate 5 is more stable.

[0024] By adopting the above technical solution, one side of the sampling frame 6 is fixedly connected to the mounting frame 9, a through opening is opened in the middle of the mounting frame 9, and the through opening is communicated with the sampling frame 6, the through opening is used to take out the water in the sampling frame 6, one side of the through opening is threadedly connected to the sealing block 11, one side of the sealing block 11 is fixedly connected to the handle, and the sealing block 11 is used to seal the through opening to prevent water leakage.

[0025] By adopting the above technical solution, the elastic sheet 91 is fixedly connected to the upper and lower ends of the opening, and the elastic sheet 91 is fixedly connected to the stopper 92 near the center of the opening. The stoppers 92 are plugged into each other, and the set stopper 92 and elastic sheet 91 serve to prevent water from flowing out of the sampling frame 6.

[0026] By adopting the above technical solution, a through groove 10 is opened in the middle of the floating plate 1, and the through groove 10 is located directly below the sampling frame 6, so that the sampling frame 6 can enter underwater for sampling after being lowered.

[0027] Rotate the sealing block 11 and remove it from the opening. Then insert the sampling tube into the opening and push the two stoppers 92. The stoppers 92 are squeezed and move to squeeze the elastic sheet 91 to contract, so that the two baffles 92 separate and no longer block the opening. The water sampled in the sampling frame 6 flows into the sampling tube, so that the sampling tube can be tested after sampling. Then open the stoppers 92 in other layers in turn and use the sampling tube to take out the water.

[0028] The implementation principle of the surface water quality monitoring sampling device of the embodiment of the present application is as follows: the sampling device is moved to the surface of the water source, and then the servo motor 3 is started, so that the servo motor 3 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the moving plate 5 to descend, and drives the sampling frame 6 to descend, so that the sampling frame 6 descends from the through slot 10 into the water, and the water completely enters the sampling frame 6 from the gap between the first baffle 81 and the second baffle 82, and then the stepper motor 7 is started again, so that the stepper motor 7 drives the rotating rod 8 to rotate, so that the rotating rod 8 drives the first baffle 81 to rotate 22.5°, and blocks the gap between the first baffle 81 and the second baffle 82 in the initial state, so that the first baffle 81 and the second baffle 82 are combined to form a partition plate to separate the sampling frame 6, and form multiple layers, so that the water in each layer cannot circulate with each other, thereby achieving the purpose of layered sampling. Then the servo motor 3 is started again, so that the threaded rod 4 drives the moving block 5 to rise, and the moving block 5 drives the sampling frame 6 to rise and completely emerge from the water surface.
