Abstract
The invention relates to a fixed area detachable bottom mud sampler and a sampling method of the fixed area detachable bottom mud sampler, and can be used in fields of environment monitor, bioengineering, and plumbing work, and is used for fixed area sampling of bottom mud and sediment of rivers, lakes, reservoirs and shallow sea areas. A sampling bailer handle and a blocking device control a handle to control the whole sampler, in sampling, the blocking device is rotated to control the handle to switch on the blocking device, a sampling bailer is arranged at the bottom of the river by a sampling bailer operating handle for sampling, after the sampling, the blocking device is switched off so as to prevent a bottom mud sample in the sampling bailer from losing and obtain a fixed sectional area of the bottom mud sample. Compared with other bottom mud samplers, the sampler can be better applied to sampling the bottom mud in a river channel with large moisture content, and has the advantages of being easy to operate, convenient to dismount and low in cost.
