[0023] Please see Figure 1-5 An automated sampling and measurement device for runoff sediment includes a protective box 1. A mounting base 10 is fixedly installed on the upper surface of the protective box 1. A peristaltic pump 9 is fixedly installed on the upper surface of the mounting base 10. A sampling tube 11 is fixedly connected to the input end of the peristaltic pump 9, and a connecting pipe 8 is fixedly connected to the output end of the peristaltic pump 9. A first through hole 24 is opened on the upper surface of the protective box 1. The bottom end of the connecting pipe 8 passes through the first through hole 24 and extends into the interior of the protective box 1. Four support columns 12 are fixedly installed on the inner bottom wall of the protective box 1. A support plate 14 is fixedly installed on the top of the four support columns 12. Three high-precision electronic balances 15 are fixedly installed on the upper surface of the support plate 14.

A turbidity sensor 16 is fixedly installed on the inner wall of the measuring cylinder 17. An ultrasonic liquid level sensor 26 is fixedly installed on the inner top wall of the protective box 1.

[0024] In this embodiment: the peristaltic pump 9 can quickly extract the mud and water in the runoff into the measuring cylinder 17 through the sampling tube 11 and the connecting tube 8. By installing the measuring cylinder 17 on the upper surface of three high-precision electronic balances 15, the sample can be weighed conveniently. The turbidity of the sample can be detected by the turbidity sensor 16, and the height of the sample can be detected by the ultrasonic liquid level sensor 26. The four support columns 12 together support the support plate 14.

[0025] As a technical optimization of this utility model, the inner wall of the protective box 1 is fixedly installed with a vertical plate 19 and a partition plate 22, and the outer surface of the vertical plate 19 is fixedly installed with a controller 18, a display screen 20 and a microprocessor 21, and the right side of the protective box 1 is fixedly inlaid with a heat dissipation window 2.

[0026] In this embodiment: the partition 22 can block the liquid at the splash point. The controller 18 is electrically connected to the peristaltic pump 9 through wires. The controller 18 can automatically start the peristaltic pump 9 at regular intervals. The three high-precision electronic balances 15, the turbidity sensor 16, and the ultrasonic level sensor 26 are all electrically connected to the microprocessor 21 through wires. The microprocessor 21 can process the detection data of the three high-precision electronic balances 15, the turbidity sensor 16, and the ultrasonic level sensor 26 to calculate the sediment content. The microprocessor 21 is electrically connected to the display screen 20 through wires. The display screen 20 can display information such as liquid level height, sample turbidity, sample weight, and sediment content in real time. Air can enter the interior of the protective box 1 through the heat dissipation window 2, thereby cooling the controller 18, the display screen 20, and the microprocessor 21.

The door 7 and the protective box 1 together protect the controller 18, the display screen 20, the microprocessor 21, the three high-precision electronic balances 15, the turbidity sensor 16, the ultrasonic level sensor 26, and the solenoid valve 13. The four support legs 4 together support the protective box 1. By opening three mounting holes 23 on the bottom surface of each support 3, the operator can use bolts to firmly install the device on the ground through the mounting holes 23.

[0031] Working principle and usage process of this utility model:

[0032] First, the staff sets the sampling interval on the controller 18 in advance. Every certain period of time, the controller 18 can automatically start the peristaltic pump 9. After the peristaltic pump 9 is turned on, the sediment and water in the runoff can be transported to the inside of the measuring cylinder 17 through the sampling tube 11 and the connecting tube 8. Then, the ultrasonic level sensor 26, three high-precision electronic balances 15 and turbidity sensor 16 can detect the height, weight and turbidity of the sample, and transmit the detection information to the microprocessor 21 through the wire. The microprocessor 21 can calculate the sediment content and other information based on the height, weight and turbidity of the sample.
