Sampling device

The utility model relates to the technical field of sampling equipment, in particular to a sampler which comprises a sampler body and a sample outlet pipe, a buoyancy ring for providing buoyancy is also arranged outside the sampler body; a sample outlet communicated with the sample outlet pipe is formed in the bottom of the sampler body, and the top of the sampler body is communicated with the outside; a blocking piece and a limiting piece for limiting the moving direction of the blocking piece are arranged in the sampler body; the blocking piece comprises a piston matched with the sample outlet; and the density of the piston is 0.004-0.024 g/cm larger than that of a sample. Through the sampler, the problems of insufficient sampling and potential safety hazards in transfer can be effectively solved. 本实用新型涉及取样设备技术领域，特别是涉及一种取样器，包括取样器本体和出样管；所述取样器本体外还设有用于提供浮力的浮力圈；所述取样器本体的底部设有与出样管连通的出样口，顶部与外界连通；所述取样器本体内设有堵塞件和用于限制堵塞件移动方向的限位件；所述堵塞件包括与出样口相匹配的活塞；所述活塞的密度比样品密度大0.004 g/cm³~0.024 g/cm³。通过本取样器，能有效解决取样不充分和转移存在安全隐患的问题。
