The invention relates to an off-sea flow-wave resistant lifting network box, wherein a network box frame is formed by an upright floating tube, three parallel horizontal floating tubes, a strengthened frame floating tube connector, a frame tube connector, a network box lifting exhaustion system, a network box descending balance control system and an anchor fixing device for lifting the network box down to bottom. The invention is characterized in that the network box frame is formed by hollow high-strength plastic tubes, the upper floating tube supports the whole weight of network box and adjusts the water flux to control the up and down of the network box, the horizontal floating tube supports the sink force of network box caused by sea flow and additional weight of workers and materialson the network box, and calculates out the floating force of horizontal floating tube and the weight in the connecting tube at the lower part of the network box, according to the network box weight and the floating force diff
