技术领域technical field
本发明属于深海沉积物取样冲击头装置领域，尤其是一种密封性能好、承重能力强以及能够减少深海沉积物取样样品遗失的采用复合密封式结构的深海沉积物取样冲击头。The invention belongs to the field of deep-sea sediment sampling impact head devices, in particular to a deep-sea sediment sampling impact head with a composite sealing structure, which has good sealing performance, strong load-bearing capacity and can reduce the loss of deep-sea sediment sampling samples.
背景技术Background technique
目前在深海沉积物大口径取样管取样活动中，主要面临的难点是由于取样管和样品管的口径较大，样品管中的样品自重也较大，活板密封得以提供较好的承重能力，但是活板间缝隙较大，在长达数小时的回收过程中，珍贵的底部样品损失严重；而莲花式密封结构叶片重叠，几乎没有间隙，密封性能好，但是承重力较小，当样品质量较大，且离开水面时样品内产生较大的正压差时，莲花式密封结构的叶片很容易失效，造成珍贵底层样品的大块脱落，因此通常莲花式密封结构不能适用于大口径的取样管和样品管。At present, in the sampling activities of large-diameter sampling tubes for deep-sea sediments, the main difficulty is that due to the large diameter of the sampling tubes and sample tubes, the self-weight of the samples in the sample tubes is also large, and the flap seal can provide better load-bearing capacity. However, the gaps between the flaps are large, and the precious bottom samples are seriously lost during the recovery process that lasts for several hours; while the leaves of the lotus-shaped sealing structure overlap, there is almost no gap, and the sealing performance is good, but the load-bearing capacity is small. When the sample quality Larger, and when there is a large positive pressure difference in the sample when it leaves the water surface, the blades of the lotus seal structure are easy to fail, causing large pieces of precious bottom samples to fall off, so usually the lotus seal structure is not suitable for large-caliber sampling tubes and sample tubes.

具体实施方式Detailed ways
附图所示，一种采用复合密封式结构的深海沉积物取样冲击头，由样品管1、取样管2、莲花式密封器3、活板式密封器4和冲击头5组成，其中，取样管2套接在样品管1的外面，取样管2与冲击头5的冲击头上部6连接；莲花式密封器3安装于样品管1的下部，莲花式密封器3的叶片7插入样品管1内；冲击头上部6与冲击头5通过固定轴8连接在一起；活板式密封器4安装于固定轴8上，11是冲击头的锥形刃口。As shown in the accompanying drawings, a deep-sea sediment sampling impact head adopting a composite sealing structure is composed of a sample tube 1, a sampling tube 2, a lotus sealer 3, a flap sealer 4 and an impact head 5, wherein the sampling tube 2 is socketed on the outside of the sample tube 1, and the sampling tube 2 is connected to the upper part 6 of the impact head 5; the lotus sealer 3 is installed on the lower part of the sample tube 1, and the blade 7 of the lotus sealer 3 is inserted into the sample tube 1 ; The upper part of the impact head 6 and the impact head 5 are connected together through the fixed shaft 8; the trap sealer 4 is installed on the fixed shaft 8, and 11 is the tapered edge of the impact head.
莲花式密封器3的管箍9外径与样品管1相同并通过冲击头上部6的管槽定位。活板式密封器4可绕固定轴8做90°转动，活板式密封器4的活板10采用较厚的不锈钢片冲压而成。图中，12是深海沉积物样品。The ferrule 9 of the lotus sealer 3 has the same outer diameter as the sample tube 1 and is positioned through the tube groove on the upper part 6 of the impact head. The flap type sealer 4 can rotate 90° around the fixed shaft 8, and the flap 10 of the flap type sealer 4 adopts thicker stainless steel sheet stamping to form. In the figure, 12 is a deep sea sediment sample.
莲花式密封器安装于样品管的下部，叶片插入样品管内，由于受管壁的挤压，呈层叠状态，消除叶片间的间隙，实现密封。活板采用较厚的不锈钢片冲压而成，具备良好的承重性能，防止大块样品脱落。冲击头在重力或振动力的作用下，通过冲击头前部的锥形刃口插入深海底部沉积物中，回收时莲花式密封器和活板式密封器复合式密封结构可确保沉积物样品不泄露，不脱落，从而获取宝贵的底部沉积物样品。The lotus-shaped sealer is installed at the lower part of the sample tube, and the blades are inserted into the sample tube. Due to the extrusion of the tube wall, they are in a stacked state, eliminating the gap between the blades and achieving sealing. The flap is stamped from thicker stainless steel sheets, which has good load-bearing performance and prevents large samples from falling off. Under the action of gravity or vibration, the impact head is inserted into the sediment at the bottom of the deep sea through the conical cutting edge at the front of the impact head. The combined sealing structure of the lotus sealer and the flap sealer can ensure that the sediment sample does not leak. , does not fall off, thereby obtaining valuable bottom sediment samples.
