Problems solved by technology

[0003] With the rapid development of water conservancy, the requirements for water conservancy monitoring facilities have also increased, and the requirements for riverbed sampling devices have also increased. However, the existing riverbed sampling devices cannot manually and flexibly control appropriate sampling. In the process of falling, the income has nothing to do with sediment, which greatly affects the normal sampling quality

Abstract

The riverbed sampling device comprises a machine body, and sliding grooves and the like are formed in the left side and the right side of the machine body. According to the invention, batch sediment particle image collection can be carried out. According to the invention, the images can be quickly and efficiently spliced, the definition and contrast of the spliced images can be obviously improved,the image data rate is greatly reduced, the sediment particle image information is accurately acquired, and the effect of conveniently ensuring the sampling speed by workers is achieved by improvingthe stability, so that the effect of improving the working efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of riverbed sampling, in particular to a riverbed sampling device. Background technique [0002] The riverbed sampler is an instrument for collecting sediment samples at a certain depth on or below the bed surface. When the sampler is lowered to the river bottom, the contact rod at the bottom of the lead fish is lifted to release the limit claw of the bucket, and then retracts. Twist the lifting cable, and use the self-weight of the instrument to drive the bucket to turn over to sample. As the sample enters the tube, the piston in the tube rises, and the partial vacuum formed by the movement of the piston can keep the sample in the tube without leakage. [0003] With the rapid development of water conservancy, the requirements for water conservancy monitoring facilities have also increased, and the requirements for riverbed sampling devices have also increased. However, the existing riverbed sampling devices...
