Further, the sampling end of the sampling rod is conical, and a plurality of sampling ports are formed in the sampling end of the sampling rod.

By adopting the scheme, foreign matters at the sampling position can be prevented from blocking the sampling rod.

Further, a torsion spring is arranged between the baffle plate and the side wall of the first pipe body.

By adopting the scheme, the baffle can be abutted against the first pipe body under normal conditions.

Compared with the prior art, the utility model has the beneficial effects that: the connecting rod can be repeatedly lifted for many times to enable the first pipe body to generate negative pressure, so that water samples are collected, and the water samples can be collected into the sampling bottle even if the single movement stroke of the piston is shorter.

Detailed Description

The following is a detailed description of the embodiments.

Examples: as shown in fig. 1 to 3, a portable water conservancy sampling rod 1, including sampling rod 1, sampling rod 1 adopts plastic hose, and sampling rod 1's right-hand member is sampling end and its transversal toper of personally submitting, and it has sampling port 2 that a plurality of intervals set up to open on the sampling end, and sampling rod 1's surface scribbles the scale mark, and the staff can confirm the depth of water of sampling department fast through the scale mark. The left end of sampling rod 1 is equipped with negative pressure subassembly, and negative pressure subassembly includes first body 3, piston 4, connecting rod 5, second body 7, separation blade 11 and sampling bottle 13, and first body 3 adopts the rigid plastic pipe, and the right-hand member of first body 3 links to each other with the left end of sampling rod 1, and the left end of first body 3 adopts the seal design. The piston 4 is installed inside the first pipe body 3 and is in sliding seal with the first pipe body 3, the right end of the connecting rod 5 is adhered to the left end of the piston 4, the connecting rod 5 penetrates through the first pipe body 3, the left end of the connecting rod 5 is adhered to the handle 6, and a worker can quickly push and pull the connecting rod 5 through the handle 6.
