TL;DR: In this article, a circulation water feeding system is proposed, which consists of a stable platform, a cylinder, a first position, a piston rod, a supporting platform and a plurality of buoyancy pipe sets.
Abstract: The invention discloses a circulation water feeding system. The circulation water feeding system comprises a stable platform, a cylinder, a first position, a piston rod, a supporting platform and a plurality of buoyancy pipe sets. The cylinder is located below the stable platform, the upper end of the cylinder is fixedly connected with the stable platform, a water inlet and a water outlet channel are arranged at the upper end of the cylinder, and a water inlet valve is arranged at the water inlet. The first piston makes contact with the inner wall of the cylinder in a sealing mode, the piston rod is fixedly connected with the first piston, the first piston can slide up and down along the inner wall of the cylinder, the lower end of the piston rod is fixedly connected with the upper side of the supporting platform, each buoyancy pipe set comprises a plurality of buoyancy pipes with buoyancy cavities provided with water flowing ports and ventilation ports and further comprises an air pipe communicated with the ventilation ports and a drive device capable of draining water in the buoyancy cavities, and the air pipes are provided with valves. When the buoyancy pipe sets ascend, the supporting platform is driven to ascend, and when the buoyancy pipe sets descend, the supporting platform is driven to descend. The problem that cost is high for building a dam can be effectively solved through the structural design of the water feeding system.
