Water inlet anti-blocking grating for hydroelectric power generation

The utility model belongs to the field of hydroelectric power generation, and particularly relates to a water inlet anti-blocking grating for hydroelectric power generation. A water inlet port is formed in one side of the protective shell, a blocking fence is arranged in the water inlet port, a first rotating rod is arranged in the protective shell, rotating blades are fixedly connected to the position, close to the lower portion, of the outer portion of the first rotating rod, and the multiple sets of rotating blades are arranged on the outer portion of the first rotating rod in a circumferential array mode; water enters from a water inlet end opening formed in the protection shell through impact, linear objects such as sea grass can be blocked and intercepted by a blocking fence, the situation that the linear objects are wound on the surfaces of rotating blades at the bottom of a first rotating rod, consequently, the first rotating rod cannot rotate, and a generator provides electric energy is avoided, and
