The invention discloses unpowered water conservancy irrigation water taking equipment for river water. The unpowered water conservancy irrigation water taking equipment comprises a lower fixing seat. Supporting legs are symmetrically and fixedly connected to the lower portion of the lower fixing seat in a left-right manner. A first bearing seat is fixedly connected to the middle portion of the front side of the lower fixing seat. A threaded ejector rod is rotationally connected to the middle of a first bearing. A rotary handle is fixedly connected to the front side of the threaded ejector rod. An ejector block is connected to the rear side of the threaded ejector rod in a threaded manner. The rear side of the ejector block is in an inclined state. Longitudinal ejector rods are symmetrically and slidably connected to the middle of the upper portion of the lower fixing seat in a left-right manner. An upper fixing seat is fixedly connected to the tops of the longitudinal ejector rods. The lower ends of the longitudinal ejector rods are matched with the ejector block. Compared with the prior art, the unpowered water conservancy irrigation water taking equipment has the beneficial effects that the structure is simple, the use is convenient, no power pump and the like are needed during irrigation water taking, and the equipment completely depends on the flowing kinetic energy of stream water and river water, so that the energy is saved effectively, and the equipment is free of being limited by a power source, can be used in more remote places and is worthy of popularization.
