Cable conveying capacity improvement system adopting hose winding and water circulation cooling

The invention discloses a cable conveying capacity improvement system adopting hose winding and water circulation cooling, and relates to the technical field of power transmission. Water circulation forced cooling of local high temperature of a cable is divided into direct cooling and indirect cooling; during direct cooling, the cable is directly immersed in water, heat is taken away through water circulation, and the problem of sealing between the cable and a sleeve needs to be solved; and during indirect cooling, the cable is buried in soil, a cooling water pipe is buried in the soil near the cable, low-temperature cooling water is introduced in the water pipe, and due to the fact that an intermediate cooling medium exists, the cooling effect is far worse than that of the direct cooling. The system comprises a hose wound on the cable in a spiral mode and a cooling circulation device connected with an inlet and an outlet of the hose, wherein the periphery of the wound hose is provided with a heat preservatio
