[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a sewage sampling device. Figure 1-4A sewage sampling device comprises a hollow tube 1, a hollow tube 2 movably arranged in the hollow tube 1, a support rod 3 movably arranged in the hollow tube 2, a support plate 4 is fixedly installed on the hollow tube 1, the hollow tube 2, and the support rod 3, a sampling bottle 5 is arranged on the support plate 4, a sealing cover 6 is arranged at the bottle mouth of the sampling bottle 5, a driving mechanism is arranged on the sealing cover 6, the driving mechanism comprises a fixing block 7 fixedly installed on the top of the supporting plate 4, a guide groove 8 is opened on the fixing block 7, a connecting block 9 is fixedly installed on the top of the sealing cover 6, and a guide block 10 matching the guide groove 8 is fixedly installed on the connecting block 9;

[0021] By adopting the above technical solution, the threaded rod 11 is rotated, and the guide block 10 is driven to rise by the guide groove 8 in cooperation with the guide block 10. The guide block 10 drives the sealing cover 6 to rise through the connecting block 9, so that the sampling bottle 5 is in an open state. When the sampling is completed, the threaded rod 11 is rotated in the opposite direction to drive the sealing cover 6 to descend, thereby sealing the sampling bottle 5 to prevent the sampling bottle 5 from being affected by sewage of different depths when it is taken out of the water.
