Description

TECHNICAL FIELD

[0001] The utility model relates to water and soil loss rate detection technical field, concretely is a dam water and soil loss rate detection device. BACKGROUND

[0002] Water and soil loss refers to the phenomenon that rainwater cannot be absorbed on site, flows downstream or erodes soil due to natural or human factors. The main reasons are large ground slope, improper land use, damaged ground vegetation, unreasonable cultivation techniques, loose soil, deforestation, overgrazing, etc. The hazards of water and soil loss include erosion and destruction of soil cultivation layer, siltation of rivers, channels and reservoirs, reduction of water conservancy project benefits, and even occurrence of flood and drought disasters, which seriously affect industrial and agricultural production.

[0003] The reference patent (publication number: CN219641260U; publication date: 2023-09-05) discloses a water and soil loss detection device, which comprises a support frame, a lifting mechanism and a sampling mechanism. The support frame comprises a plurality of support rods arranged circumferentially, and the top of the plurality of support rods is connected by a mounting seat. The lifting mechanism comprises a lifting rod, the outer wall of the lifting rod is provided with a thread, and the lifting rod is inserted into the mounting seat and connected with the mounting seat by screw thread. The lifting rod is located between the plurality of support rods. The sampling mechanism comprises a sampling sheet and a limiting ring. A plurality of sampling sheets are rotatably arranged at the bottom end of the lifting rod, and the plurality of sampling sheets can be folded inward. The limiting ring is threadedly connected to the bottom end of the lifting rod and can be clamped on the outside of the sampling sheet.

[0004] Water and soil loss monitoring refers to the monitoring and detection work of soil erosion and soil conservation measures. Soil erosion monitoring mainly monitors the process of soil and parent material being destroyed, eroded, transported and deposited caused by natural factors and human activities, as well as the current erosion situation. In order to monitor the condition of water and soil loss, soil sampling will be carried out regularly, and by observing and analyzing the composition of the extracted soil, the degree of water and soil loss at this place can be calculated.

[0005] Based on the aforementioned patents, in the field of dam soil erosion rate detection, soil sampling is a crucial preliminary step for obtaining test samples and conducting subsequent analysis. However, traditional soil sampling equipment is extremely inconvenient to operate when sampling dams with different terrains. Some equipment requires disassembly and reassembly of the entire structure to adapt to the sampling needs of different locations. Frequent disassembly and reassembly not only consume a lot of time and manpower but also easily lead to damage to equipment components and reduce the service life of the equipment. Furthermore, most equipment is difficult to flexibly adjust the angle of the soil sampling blade. When facing dams with sloping surfaces, such as gentle slopes, steep slopes, and other complex terrains, it is impossible to ensure that the sampling blade cuts into the soil in a suitable posture, making it very easy for incomplete sample collection to occur during the sampling process. Therefore, this utility model provides a dam soil erosion rate detection device. Utility Model Content
