The technical scheme adopted for solving the technical problems is as follows:

the sewage sampling pump comprises a storage battery, an electromagnetic valve, a sewage pump body, a counterweight barrel and a sampling bottle, and is characterized in that the counterweight barrel is divided into an upper independent counterweight bin and a lower independent counterweight bin and a component bin, a water adding pipe is arranged at the upper end of the counterweight bin, a sealing cover is arranged at the upper end of the water adding pipe, the sewage pump body is arranged in the component bin, and a liquid inlet pipe and a liquid outlet pipe of the sewage pump body are positioned outside the component bin; the upper end of the liquid outlet pipe of the sewage pump body is connected with a fixed ring at the upper end of the counterweight bin, a pull rope is arranged in a ring sleeve of the fixed ring, a hose is arranged at the outer side of the upper end of the liquid outlet pipe, and one end of the electromagnetic valve is connected with the other end of the hose; the battery is mounted in the component box.

Further, the counterweight barrel is made of transparent materials, and scale marks are printed at the front end of the counterweight bin.

Further, the sewage pump body is hermetically positioned in the component bin.

Further, water is filled in the counterweight bin.

Further, the sampling bottle has a plurality of, and every sampling bottle is supporting to have the bottle plug, and the upper end bottleneck internal diameter of sampling bottle is greater than the external diameter of flow pipe.

The utility model has the beneficial effects that: before this novel sampling, the sampling personnel combines the digital scale of counter weight storehouse front end as required sampling, packs into appropriate amount of counter weight water in its inside, then drops into the sampling area wholly, because there is the water of counter weight in the counter weight storehouse, and sewage pump body can sink into corresponding water in situ and carry out sewage sampling, and sewage pump body obtains in the electric work back pumps the sampling bottle to the sewage in the corresponding water in situ, accomplishes the sampling. Because the utility model discloses do not need the artificial degree of depth that fixes sewage pump body or its inlet tube lie in corresponding water layer, consequently can bring the convenience for the sampling personnel, and can correspondingly improve sewage sampling efficiency. Based on the above, the utility model has good application prospect.
