The invention discloses a self-floating type underwater sampling device, and belongs to the technical field of water sampling, the self-floating type underwater sampling device can realize that when water at the river bottom is sampled, only the device disclosed by the invention needs to be thrown into the water, and when a trigger frame sinks to the river bottom, a second piston moves upwards through water pressure, so a third piston is driven to move upwards through a transmission rod, and the third piston is capable of extracting water needing to be sampled while moving upwards. When the second piston moves upwards, a needle is pushed by a push rod to pierce a water storage balloon, so that a reaction block reacts with the water in the water storage balloon to generate gas, at the moment, gas enters a first air bag to generate an upward moving force, and when a fixed block is dissolved by water, a balancing weight is separated from a supporting rod, and the first air bag can drive the device to float out of the water surface, namely, when the water at the river bottom is sampled, the actions of water entering, sampling and floating can be automatically completed without using a long rope.
本发明公开了一种自浮式水底采样装置,属于水采样技术领域,一种自浮式水底采样装置,它可以实现在对河底的水进行采样时,只需将本发明装置一起扔入水中即可,等待触发框沉至河底时,通过水压使第二活塞向上移动,以此同时通过传动杆带动第三活塞也向上移动,而第三活塞在向上移动的同时即可对需要采样的水进行抽取,当第二活塞向上移动时通过推杆推动扎针刺破储水气球使反应块与储水气球内的水进行反应产生气体,此时气体进入到第一气囊产生向上移动的力,而当固定块被水溶解后配重块脱离支撑杆,第一气囊即可带动本发明装置漂浮出水面,即对河底的水进行取样时不需要使用长绳即可自主完成下水、取样、漂浮的动作。
