The utility model discloses an internal concave sampling head for deep undisturbed sediment sampling in deep water area, which comprises a screw buckle and an internal and external double wall sampling head. The screw buckle is screwed on the sampling rod, and the inner and outer double wall sampling heads are connected with the PVC liner; the inner and outer double wall sampling heads include the outer wall of the sampling head and the inner wall of the sampling head. The utility model improves the original single outer wall into the inner and outer double walls, the design can ensure that the mud sample does not enter the gap between the liner and the inner wall of the sampling pipe during the sampling process, so as to facilitate the smooth removal of the PVC liner, and at the same time, it can prevent the inner PVC pipe from being broken due to vibration when the single outer wall encounters hard objects during the sampling process, resulting in incomplete sampling. The double wall design not only protects the internal PVC pipe from damage during the sampling process, but also increases the hardness of the whole sampling head. It can be used not only in the sampling of sediment samples, but also in the sampling of soil samples.
【技术实现步骤摘要】
一种用于深水水域深层原状底泥采样用的内凹式取样头
本专利技术属于纳污坑塘及湖泊治理
,涉及一种用于深水水域深层原状底泥采样用的内凹式取样头。
技术介绍
当前,受污染坑塘及湖泊治理正在得到越来越广泛的重视,在纳污坑塘及湖泊治理过程中,底泥的采样和调查必不可少。然而取样工作能否顺利进行,关系到采样器的每个细节的设计。本专利技术针对常见取样头做出了改进,常用的取样头是单外壁,在取样过程中特别是遇到坚硬物体时容易发生PVC衬管断裂变形,且底泥黏在PVC管与外壁的缝隙内,导致样品不易取出,同时单外壁取样头特别难清洗,很容易导致样品间的相互干扰。本专利技术改进后的内外双壁内凹式取样头解决了常见取样头取样所遇到的上述问题,能够实现快速、高效、完整、无污染的取样,特别适用于采取深层底泥下土壤的取样。
技术实现思路
为实现上述目的,本技术公开了一种用于深水水域深层原状底泥采样用的内凹式取样头,它包括螺旋扣、内外双壁取样头,其特征在于螺旋扣1拧在取样杆上,内外双壁取样头与PVC衬管连接;所述的内外双壁取样头包括内凹式采 ...
