The invention discloses an
underwater plastic bag garbage collecting device, and belongs to the field of water garbage removal. The
underwater plastic bag garbage collecting device is composed of a
barrel, a first battery set, a first controller, a motor installing plate, a
drive motor, an
impeller, a rotation speed monitor, a transmission rod, a speed
reducer, a lower supporting rod, an upper supporting rod, stab sticks, stab stick connectors, a motor cover, an adsorption connecting rod, adsorption blocks, a battery set cover, a controller cover and a filter net. The
barrel is of a cylindrical structure. The filter net is arranged at the upper end opening position of the
barrel. The motor installing plate is arranged and fixed in the barrel. An output shaft of the
drive motor penetrates the motor installing plate. The
drive motor is vertically installed and fixed to the motor installing plate, and the
impeller is arranged on the output shaft of the drive motor. The device can finish collecting work of
underwater plastic bag garbage; an axial flow draught fan similar structure is formed through combination of the
impeller and the barrel is utilized, the
surface layer of water slowly flows towards the device, and the process that plastic bags floating and suspending in water gradually move towards the device is finished.
