The utility model discloses a sampling device for water environment detection, which comprises a filtering mechanism, a body and a sampling pipe, one side of the body is provided with a handle, one side of one end of the body is provided with a switch, the bottom end of the body is provided with the sampling pipe through a connecting piece, and one side in the body is provided with an electromagnet. A permanent magnet is arranged in the body on one side of the electromagnet, and a connecting rod is arranged in the body on one side of the permanent magnet. When the device is used, if the lengthis not enough, a worker turns on the switch, the storage battery provides electric energy, and the electromagnet is powered on, so that repulsive force is generated between the electromagnet and thepermanent magnet, the permanent magnet moves towards the side away from the electromagnet to drive the connecting rod to extend, and meanwhile the buffer spring deforms to increase buffering and prevent overlarge repulsive for
