The invention relates to a hydroelectric power generation device with a bird repelling function. The hydroelectric power generation device with the bird repelling function comprises a base, a fixed box, a fixed plate, a power generation mechanism and a bird repelling mechanism, wherein the power generation mechanism comprises a power generation
assembly and an adjusting
assembly, and the bird repelling mechanism comprises a locating plate, a gong, a bird repelling
assembly and a return assembly. According to the hydroelectric power generation device with the bird repelling function, adjusting for a rotating plate is realized through
buoyancy of water, one side of the rotating plate is located in the water, the upper portion of the rotating plate makes contact with air, therefore resistance above the rotating plate is reduced, and the power generation efficiency is increased,
water flow enters the fixed box through a water inlet groove, and then cooling for a power generator is realized; meanwhile, the heat dissipation effect is improved through the flowing
water flow, birds are repelled through sound made by an
impact rod and the gong, the rotation of the rotating plate and the heat dissipation of the power generator are realized through
impact force of water conservancy; and meanwhile, the operation of the bird repelling mechanism can be realized, and the use practicability is improved.
