Runoff sediment automatic monitoring and sampling device

Abstract

The invention discloses a runoff sediment automatic monitoring and sampling device, which comprises a transversely-arranged bottom plate, wherein a fixing pile is installed at the lower end of the bottom plate, a transverse sampling rod parallel to the bottom plate is installed at the upper end of the bottom plate, and a vertical sampling rod is correspondingly hinged to the right end of the transverse sampling rod by means of a lockable hinge assembly; sampling holes are formed in the transverse sampling rod and the vertical sampling rod, sampling pipes which protrude upwards and are uniformly arranged at intervals are further arranged on the transverse sampling rod, and the sampling pipes are correspondingly communicated with the sampling holes in the transverse sampling rod; and sampling pipes which transversely extend towards the left side and are uniformly spaced are arranged on the vertical sampling rod. The runoff sediment automatic monitoring and sampling device is wide in overall sampling range and precise in sampled data, multiple sampling modes can be achieved through transformation, sampling of the bottom part of water flow and a slope body is achieved, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of runoff monitoring and sampling equipment, in particular to an automatic monitoring and sampling device for runoff sediment. Background technique [0002] In the prior art, the river runoff process will drive the sediment flow at the bottom of the flow. In the prior art, in order to monitor the soil erosion of the sediment during the runoff process, the runoff water body is usually sampled, and then the soil loss is monitored by analyzing the sediment content. situation; in the prior art, most of the samples are taken in the form of manual sampling, and the sampling effect is poor, while the equipment usually used in the field of equipment is water pump type extraction sampling, but when sampling with existing equipment, the sampling area is too concentrated, The range is small, and it cannot truly and accurately reflect the runoff and sediment loss; and the existing sediment loss monitoring usually needs ...
