Problems solved by technology
The sampler in the related art is difficult to collect the sediment samples in the deep layer of the river bed, and the sediment samples cannot be well protected after collection, so as to prevent the samples from being washed away by the water flow during the ascent process, and it is difficult to recover the base. It cannot meet people's needs and has a certain impact on people's use process

Abstract
The invention discloses a riverbed bottom sediment sampler. The riverbed bottom sediment sampler comprises a base, a sampling tube and a sampling cylinder, a sampling groove is formed in the middle ofthe base, the base is provided with an inflating airbag, the inflating airbag is provided with an inflating opening, the sampling tube is connected into the sampling groove in an inserted mode, the lower end of the sampling tube is open to form a sampling opening, a sample accommodating cavity with the open side wall is limited in the sampling cylinder, the sampling cylinder is movably connectedto the lower end of the sampling tube in an inserted mode between the first position and the second position, when the sampling cylinder is located at the first position, the sampling cylinder is accommodated in the sampling tube, and when the sampling cylinder is located at the second position, the sampling cylinder extends out of the sampling tube from the sampling opening. Sinking and upward-floating of the base are controlled through the inflating airbag, and thus convenience can be provided for sampling and base recovering; and when the base rises, the sampling cylinder can be controlledto slide to the first position in the sampling tube, and the situation that a sample in the sample accommodating cavity is washed away by a water flow in the upward-floating process of the base is prevented.
Description
technical field [0001] The patent of the present invention relates to the technical field of sediment sampling equipment, in particular to a riverbed bottom sediment sampler. Background technique [0002] An instrument for measuring sediment content, sediment transport rate and sediment particle gradation by taking suspended sediment water samples, transported sediment and bed sand samples in the river. The basic requirement of the river bed sediment sampler is to sample as much as possible The performance of the sampler has a decisive influence on the quality of the sediment test. The sampler in the related art is difficult to collect the sediment samples in the deep layer of the river bed, and the sediment samples cannot be well protected after collection, so as to prevent the samples from being washed away by the water flow during the ascent process, and it is difficult to recover the base. It cannot meet people's use needs and has a certain impact on people's use proces...
