At present, nuclear power is increasingly widely applied as one of clean energy in the field of power generation. In nuclear power plants, whip-hit prevention structures are often used as transitions between nuclear islands and conventional islands. And high-energy pipelines such as a main steam pipe and a main water supply pipe need to pass between the nuclear island and the conventional island. In order to defend the phenomena of jetting and pipe throwing caused by pipe breakage of the high-energy pipeline under an extreme working condition, the anti-throwing piece is required to be arranged in the anti-throwing structure so as to resist huge throwing force under the action of the pipe throwing of the high-energy pipeline. Therefore, the structure safety of the nuclear island and the conventional island is guaranteed, and the impact of the whipping action is reduced to the minimum.
