Detailed ways

Example

A portable depth-measurable field water body sample collector, as shown in the figure, includes: a body 5, a top cover 1, a measuring rope 8, and a bottom cover 6. The body 5 is a cylinder with upper and lower openings, The bottom cover 6 is a disc with a central water hole 601. The disc of the bottom cover 6 is provided with female threads 602. The upper and lower parts of the body 5 are respectively provided with male threads. Seal to prevent the collected water samples from overflowing. The water inlet rubber valve 4 is arranged in the body 5 on the top of the bottom cover 6, and the water inlet rubber valve 4 is a "T" shaped valve, the upper part is a circular flat plate, and the lower part is a cylindrical center valve stem 401, and its center valve stem 401 wears Pass through the central water hole 601 of the bottom cover 6 and have a water inlet gap with the central water hole 601. The top of the central valve stem 401 is locked by the limit lock pin 4011 to prevent it from falling off when entering the water. The diameter of the upper circular plate is larger than that of the bottom cover. The central water hole has an aperture of 601mm. When the sampler is lifted, the circular plate falls to automatically close the bottom cover 6 .
