It is characterized by high reliability, long service life, no environmental pollution, the ability to generate electricity independently and grid-connect, and is favored by enterprise organizations in various countries, having broad development prospects.

[0003] The existing floating photovoltaic system has problems that the silt cleaning problem cannot be solved, and at the same time, piling cannot be carried out in the regulating pond, and large-span steel frames cannot be used. To solve these problems, the following solutions are proposed. Summary of the Invention

The top end of the regulating pond is fixed with an assembly steel frame through bolts. The assembly steel frame spans across the regulating pond. An embedded steel plate is fixedly connected to the assembly steel frame. The cantilevered steel structure includes a support frame. A plurality of assembled steel column members are clamped to the inner wall of the bottom end of the support frame. A plurality of steel columns are clamped to the inner wall of the bottom end of the last assembled steel member. The plurality of steel columns are fixed to the top end of the embedded steel plate. The steel columns and the embedded steel plate are integrally formed. An external steel seat is connected to the outer wall of the embedded steel plate.

[0007] By arranging an assembly steel frame at the top of the regulating pool and making it span the outer wall of the regulating pool, and then arranging an embedded steel plate at the top of the assembly steel frame to fix the assembly steel member at the very end of the cantilevered steel structure, the cantilevered steel structure can be stably established on the top of the regulating pool, which is very suitable for water conservancy facilities with abundant solar energy resources, low building shading rate, and no need for additional land acquisition, such as reservoirs, sluice stations, regulating pools, etc., and installing it on the regulating pool in this way will not affect the normal use of water supply facilities.
