Sampling device for water quality detection

The invention relates to the field of water quality sampling devices, in particular to a sampling device for water quality detection, which comprises a water quality sample sampler, a cleaning mechanism is arranged at the lower part in the water quality sample sampler, a water filtering mechanism is arranged on the inner side of the cleaning mechanism, and the water filtering mechanism is arranged at the bottom in the water quality sample sampler; the water quality and water sample sampler is used for sampling water quality of a water area to be detected; the water filtering mechanism is used for filtering organisms with relatively small sizes in water during sampling; the cleaning mechanism is used for blocking aquatic plants, deadwood and leaves floating in water during sampling and can clean a filter cover in the water filtering mechanism to avoid blockage of the filter cover, multi-point sampling of the water area is achieved, and therefore the subsequent water quality detection result of the water area c
