Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a sewage sampling device for environmental monitoring, includes reel 1, it has stay cord A2 and stay cord B3 to wind on

reel

1, and 1 downside of reel is equipped with connecting

plate

6, and 6 downside of connecting plate are equipped with balancing

weight

7, and 7 top surfaces middle part fixedly connected with sealing plug 9 of balancing weight, and 9 upsides of sealing plug are equipped with sample bottle 10, and the inside bottom surface fixedly connected with filter screen 11 of

sample bottle

10, and 10 upside front portions of sample bottle are connected with delivery port 12, and the fixed section of thick bamboo 15 of 10 top surfaces middle part fixedly connected with of sample bottle.

According to the utility model, the pull rope A2 and the pull rope B3 are different colors, when the pull rope A2 is pulled, the sampling bottle 10 is influenced by self weight and driven by the spring A14, the through hole 13 on the bottom surface of the sampling bottle 10 is abutted against the water stop plug 9, so that the sampling bottle 10 is kept in a sealed state, after the pull rope B3 is pulled, the pull rope B3 firstly drives the slider 16 to slide upwards to the top in the fixed cylinder 15, then the sampling bottle 10 is pulled by the cooperation of the slider 16 and the fixed cylinder 15, at the moment, the pull rope A2 is loosened, the balancing weight 7 moves downwards under the influence of self weight and drives the spring A14 to compress, meanwhile, the balancing weight 7 drives the water stop plug 9 to be canceled from abutting against the through hole 13, the sampling bottle 10 can sample sewage at the moment, after sampling, the pull rope B3 is loosened, the spring A14 resets to drive the sampling bottle 10 to descend to abut against the water stop plug 9, the pull rope A2 is driven by rotating the reel 1 to drive the pull rope A2 to pull the connecting plate 6 upwards, and sampling is completed.
