Auxiliary device for sampling detection of water conservancy project

The utility model discloses an auxiliary device for water conservancy project sampling detection, which comprises a support frame, a sliding block slidably sleeved in the upper end of one side of the support frame, a movable frame fixedly welded at the upper end of the sliding block, an electric cylinder slidably sleeved in the movable frame, a screw rod connected in the electric cylinder through threads, a first motor fixedly connected with one end of the screw rod, and a second motor fixedly connected with the other end of the screw rod. According to the auxiliary device for water conservancy project sampling detection, an electric cylinder can be driven to transversely and longitudinally move by starting a first motor and a second motor, so that a sampling pipe samples water sources at different positions, a lower magnetic block is driven to be separated from an upper magnetic block by moving the sampling pipe downwards, and the sampling pipe can be conveniently moved towards the side face to be quickly di
