Water quality sampling device for environmental protection detection

The invention discloses a water quality sampling device for environmental protection detection, and relates to the technical field of detection sampling devices. The water quality sampling device comprises a sampling platform arranged on the water surface, and further comprises a sampling pipe, wherein a through hole movably matched with the sampling pipe is formed in the sampling platform, mounting grooves are formed in the sampling platform on the two sides of the through hole, two guide plates are mounted at the through hole in a matched mode, mounting flanges matched with the mounting grooves are arranged on the outer sides of the guide plates, limiting switch structures are arranged on the two sides of the ends of the guide plates, and two channels are formed between the two guide plates. Through cooperative use of the sampling pipe and the extension pipe assembly, in the use process, change can be conducted at will according to the requirement for the sampling depth, and samplingoperation is simple. 本发明
