The invention discloses a sampling device for water environment monitoring, which comprises a remote control ship, a sample collecting and placing assembly, a pneumatic sample collecting and placing assist device, a host, a sampling bottle and a remote controller, the sample collecting and placing assembly comprises a sample collecting and placing motor, a winding drum and a wire, and the pneumatic sample collecting and placing assist device comprises a shell, a compressed gas cylinder, an air inlet one-way air valve, an air outlet one-way air valve, an air bag and an air pipe. One end of the wire is fixed on the drum wall of the winding drum, the other end of the wire is wound outside the drum wall of the winding drum for a plurality of circles and then is connected with the machine shell, and the air inlet one-way air valve and the air outlet one-way air valve are installed at an air inlet connector and an air outlet connector of the air bag respectively and only allow air flow to enter or leave a bag cavity of the air bag. The compressed air bottle is located in the machine shell and connected with the air inlet one-way air valve through an air pipe, the multiple sampling bottles are installed on the outer wall of the machine shell, and the expansion degree of the air bags can be adjusted through air inlet and air outlet of the air bags, so that the sampling bottles are matched with the gravity of the air bags and the gravity of loaded objects, and lifting of the sampling bottles is achieved.
