Abstract

The invention provides a device for vertically throwing a sediment sampler, and relates to the technical field of underwater sediment sampling. The device comprises a guide cylinder, a righting mechanism is fixed at the bottom of the guide cylinder, a pressing handle and a gradienter are arranged at the top of the guide cylinder, and a boosting tube is in threaded connection in an inner hole at the upper part of the guide cylinder. The bottom of guide cylinder is the horn mouth, and the righting mechanism includes a tripod fixed with the guide cylinder and three or more than three outward inclined landing legs fixed on the tripod. The problem that the sampler is easy to skew in the throwing process in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of underwater sediment sampling, in particular to a device for vertically dropping a sediment sampler. Background technique [0002] The sediment columnar samples of deep-water lakes and reservoirs are mainly collected with a plexiglass tube with an inner diameter of 54mm in conjunction with a sampler (the sampler with application number CN200520000502.0), and the sampler needs to be inserted into the collected sediment and kept for 24 hours to achieve The effect of in situ measurements. Since the plexiglass pipe used to store the sediment is thinner and longer in length, the sampler is easily skewed during the manual placement of the sampler, resulting in measurement failure and reducing the efficiency and quality of sampling. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a device for vertically placing the sediment sampler, whi...
