Anti-collision method of water blocking gate of navigation lock and ship lift

The invention relates to the field of water conservancy and hydropower engineering navigation structures, in particular to an anti-collision method of a navigation structure water blocking gate. A rigid anti-collision beam is arranged right in front of the navigation structure water blocking gate, and two ends of the rigid anti-collision beam are respectively connected with an automatic lifting driving device; the rigid anti-collision beam has the character that during a plastic deformation stage, strain is increased, but stress is not increased; and accordingly plastic deformation of the rigid anti-collision beam can be utilized to absorb kinetic energy of stalled ships. The anti-collision method of the navigation structure water blocking gate overcomes the shortcoming of large relative structural design difficulty caused by oversize collision load on the rigid anti-collision beam design by basing on rigid anti-collision beam elastic deformation energy dissipation principle; solves problems including complic
