Underwater suspension tunnel for preventing waves by using marine aquaculture net cage

According to the technical scheme, the underwater floating tunnel capable of preventing waves through the mariculture net cages comprises a floating tunnel pipe body, and the floating tunnel pipe body is anchored to a seabed through an anchor cable; a plurality of mariculture net cages are arranged on the two sides of the suspension tunnel pipe body at intervals in the axial direction of the suspension tunnel pipe body, and each mariculture net cage comprises a frame system, a netting system, an anchoring system and a counterweight system; all the mariculture net cages form a linear array on the two sides of the floating tunnel pipe body and are used for resisting impact of waves on the floating tunnel pipe body, so that the stability of the floating tunnel pipe body is improved, and meanwhile the service life of the anchor cable is prolonged. Wherein the mariculture net cage plays dual roles of wave prevention and aquatic product culture, so that the safety of the floating tunnel in water can be guaranteed,
