For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Please refer to Figures 1-3 , a continuous sampling and measuring device for runoff sediment in soil and water conservation monitoring, including a main body housing 1, a sampling runner 2, and a clamping component. The sampling runner 2 is arranged on the left side of the main body housing 1, and the clamping component is arranged on the back side of the sampling runner 2.

[0029] On the top left side of the main body housing 1, a measuring system housing 3 is fixedly installed. On the left side of the main body housing 1, the sampling runner 2 is rotatably installed. At the center of the front surface of the sampling runner 2, a driving motor 5 is arranged. On the outer surface of the sampling runner 2, a circle of sampling support rods 6 is arranged. At the outer ends of the sampling support rods 6, sampling cylinders 7 are arranged.

[0030] Through the continuous rotation of the sampling runner 2, in cooperation with the design of the sampling support rods 6 and the sampling cylinders 7, continuous sampling of sediment in the runoff can be achieved. This design avoids the data discontinuity and errors that may be brought about by traditional intermittent sampling, making the monitoring results more accurate and helping to more comprehensively reflect the actual situation of soil erosion.

[0031] In this embodiment, a telescopic support leg 4 is movably installed at the bottom of the main body housing 1. On the outer surface of the driving motor 5, a telescopic rod fixed to the ground is arranged. The output end of the driving motor 5 is connected to the front surface of the sampling runner 2. On the back side of the sampling runner 2, a fixed shaft 11 is fixedly installed, and the fixed shaft 11 is on the same straight line as the driving motor 5.

[0032] It should be noted that the design of the telescopic support leg 4 movably installed at the bottom of the main body housing 1 enables the device to be adjusted in height according to the actual situation of the monitoring location, increasing the adaptability and stability of the device. At the same time, the driving motor 5 is fixed to the ground through the telescopic rod, ensuring the stability of the driving motor 5 during operation.

[0033] In this embodiment, eight sampling support rods 6 arranged in a circumferential array are fixedly installed on the outer surface of the sampling runner 2. Sampling cylinders 7 are fixedly installed at the ends of the eight sampling support rods 6 far from the driving motor 5. Sealing covers 10 are fixedly installed on both the front and back sides of the sampling cylinders 7.

[0034] It should be noted that the uniform distribution of multiple sampling cylinders 7 makes the sampling more comprehensive, capable of covering a wider runoff area, thereby improving the representativeness of sampling, which helps to more accurately reflect the distribution and variation of runoff sediment in the entire monitoring area.

[0035] In this embodiment, the outer surface of the sampling cylinder 7 is provided with an inclined notch, and the inner cavity of the sampling cylinder 7 is provided with a flow-through groove 9 extending to the sampling support rod 6. Diagonal positioning branch pipes 8 are fixedly installed on the back sides of the eight sampling support rods 6, and the positioning branch pipes 8 communicate with the flow-through groove 9.

[0036] It should be noted that the design of the inclined notch enables sediment in the runoff to more easily enter the sampling cylinder 7 during the sampling process. When the sampling runner 2 rotates and dips into the runoff, the water flow will flow into the sampling cylinder along the inclined notch, reducing the water flow resistance and improving the sampling efficiency.

[0037] The opening of the flow-through groove 9 forms an unobstructed channel between the inside of the sampling cylinder 7 and the sampling support rod 6, ensuring that the sediment sample can be smoothly transferred from the sampling cylinder 7 to the positioning branch pipe 8 for subsequent processing. This design avoids the retention or blockage of the sample in the sampling cylinder, ensuring the continuity and accuracy of sampling.

[0038] The clamping component includes a measurement receiving pipe 16. The measurement receiving pipe 16 is arranged on the front surface of the measurement system housing 3. A flow-through pipe 14 is connected to the front surface of the measurement receiving pipe 16, and the flow-through pipe 14 communicates with the sampling cylinder 7.

[0039] In this embodiment, flow-through pipes 14 are respectively connected to the back sides of the eight positioning branch pipes 8. A common limiting ring 13 is fixedly installed on the outer surfaces of the eight flow-through pipes 14. A positioning clamping rod 12 clamped inside the flow-through pipe 14 is fixedly installed on the back side of the fixed shaft 11.

[0040] It should be noted that flow-through pipes 14 are respectively connected to the back sides of the eight positioning branch pipes 8. This design ensures that the samples obtained from each sampling cylinder 7 can be quickly and smoothly transferred to the measurement receiving pipe 16 through the flow-through pipes 14.

[0041] The limiting ring 13 is fixedly installed on the outer surface of the flow-through pipe 14, which not only plays a role in stabilizing the flow-through pipe 14 but also ensures the accuracy and consistency of the connection process of the flow-through pipe 14. At the same time, the positioning clamping rod 12 fixedly installed on the back side of the fixed shaft 11 is clamped inside the flow-through pipe 14. This double fixation method further enhances the connection stability between the flow-through pipe 14 and the sampling runner 2, reducing the risk of detachment or displacement caused by vibration or external forces.

[0042] In this embodiment, a positioning card slot 17 is formed on the front surface of the measurement receiving tube 16. The flow tube 14 is snap-fitted inside the positioning card slot 17. A receiving tube opening 18 is formed on the front surface of the measurement receiving tube 16, which is located directly above the positioning card slot 17. Discharge openings 15 are formed inside each of the eight flow tubes 14, and the discharge openings 15 can communicate with the receiving tube opening 18.

[0043] It should be noted that the positioning card slot 17 formed on the front surface of the measurement receiving tube 16 provides an accurate docking position for the flow tube 14. This snap-fitting method not only simplifies the installation process but also ensures a tight connection between the flow tube 14 and the measurement receiving tube 16, reducing the risk of sample leakage or contamination caused by loose connection.

[0044] The receiving tube opening 18 is located directly above the positioning card slot 17 and corresponds to the discharge openings 15 inside the flow tube 14. When the sample in the flow tube 14 reaches the discharge opening 15, it can smoothly flow into the receiving tube opening 18 and enter the measurement system. This design ensures the efficient collection and transmission of the sample, avoiding sample retention or loss.

[0045] The beneficial effects of the above embodiment are as follows:

[0046] By driving the sampling runner 2 to rotate through the driving motor 5, the sampling cylinder 7 can continuously sample from the runoff. This automated sampling method not only improves the sampling efficiency but also reduces the complexity and error of manual operation, ensuring the continuity and stability of sampling. At the same time, the sample in the sampling cylinder 7 enters the flow tube 14 through the flow groove 9 and the positioning branch pipe 8, and then is transmitted to the measurement receiving tube 16 through the flow tube 14, making the collection and transmission of the sample efficient and smooth, reducing sample retention and loss, and ensuring the integrity and representativeness of the sample.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
