[0072] Working principle: Before sampling, the rope is tied to the rope loop 11 to lift the entire columnar sampler of the bottom mud of the river and lake reservoir. At this time, the rod 13 and the hook hammer 12 are hooked together, the rubber plug 15 is pulled up, and the spring 14 is compressed. . When the columnar sampler for the bottom mud of the river and lake reservoir contacts the bottom of the river and lake reservoir, the hook hammer holder 10 moves down due to gravity in the iron rings 91 on both sides of the rubber stopper holder 9, and the rubber stopper 15 is also under the action of gravity and spring 14. Move down, when the rubber stopper 15 moves down to the tail main frame 8, the rubber stopper 15 and the pull rod 13 can no longer move down, and the hook hammer bracket 10 with the hook hammer 12 continues to move down, at this time the hook hammer 12 is due to The cause of the deflection of the center of gravity rotates, and the lever 13 is disconnected. The rubber stopper 15 plugs the tail main frame 8 under the action of the spring 14 to seal the floating water of the bottom mud in the plastic tube 2 of the sampling column, and then pull the sampler out of the water through a rope. Unscrew the sampling column part (sampling column cutting head 1 and sampling column plastic tube 2) from the other parts of the sampler, and collect the floating water from the bottom mud into the sampling bottle through the silicone tube siphon. After collecting the floating water, The sampling column cutting head 1 is unscrewed and separated from the sampling column plastic tube 2, and then the sampling column plastic tube 2 is opened to collect the sediment samples in sections.
