Sewage collection device for environment detection

The utility model discloses a sewage collecting device for environment detection, which comprises a case, a driving mechanism and sampling mechanisms, a driving bin is arranged in the case, a driving mechanism is arranged in the driving bin, a plurality of groups of sampling mechanisms are arranged below the driving bin, and a double-output-shaft motor of the driving mechanism is slidably mounted in the driving bin. A contact gear is fixedly installed on an output shaft on one side of the double-output-shaft motor, the contact gear is in contact connection with a controller switch of the push rod controller, the controller switch is pressed down through pressing of the contact gear so that the push rod controller can work, and the push rod controller controls the electric push rod to work. Continuous sampling of the sampling mechanism is achieved through the driving mechanism, different sewage samples in the same area or sewage samples in different areas can be collected, the sewage sampling rate of the devic
