When sampling, tie the wire rope to the pull ring 503, then slowly put the device into the river water, support it by the third spring 803, keep the cone block 804 away from the rectangular frame 705, and pull the wire rope upward when it reaches the specified depth After moving once, the wire rope can drive the pull ring 503 and the sliding rod 501 to move upward, and the sliding rod 501 can drive the limit block 802 and the conical block 804 to move during the movement. Move, due to the different heights of the multiple rectangular frames 705, the conical block 804 contacts one side of the inner ring of the rectangular frame 705 close to the middle of the box 1. At this time, the conical block 804 presses the rectangular frame 705 to the side of the box 1. When the middle part moves, the rectangular frame 705 can drive the rectangular rod 702 and the positioning block 703 to move during the movement. When the piston plate 601 is moved upward in the water storage tank 301 by the restoring force of the first spring 604, the piston plate 601 forms a negative pressure at the bottom of the water storage tank 301 during the movement, and the water flow enters the water storage tank 301 from the water pipe 302 at this time. , when the water storage tank 301 is filled with water, the vertical rod 602 moves to the top, and the through hole 707 reaches the height of the positioning block 703, and the positioning block 703 enters the through hole 707 through the restoring force of the second spring 704, thereby locking the The vertical rod 602 of the water storage tank 301, the rectangular frame 705 is also far away from the conical block 804 on the limit block 802 at this time, the device can continue to dive to sample the next water storage tank 301, and finally all the water storage tanks 301 are completed after sampling. The device is pulled out, and then the sliding rod 501 is rotated to disengage the threaded post 502 at the bottom end from the threaded hole 805 , then the box cover 2 is opened and the handle 603 is pushed downward to make the sample flow out of the water pipe 302 to complete sampling.
