Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-3In this embodiment of the utility model, the water conservancy project ecological fishway construction device includes a ditch 1. A lock hole 4 is provided on the upper surface of the ditch 1. A lock cap 5 is threadedly connected to the through part of the lock hole 4. The bottom of the lock cap 5 passes through the through part of the lock hole 4 and is threadedly connected to a support column 3. A foundation pit 2 is installed at the bottom of the support column 3. The upper part of the groove side of the foundation pit 2 is fixedly connected to the side of the ditch 1. A gate body 6 is installed at one end of the ditch 1.
[0020] The gate body 6 also includes an outer frame 7 that is fixedly connected to one end of the ditch 1. Gear 11 and gear 2 12 are respectively installed on the upper and lower parts of the outer wall of the outer frame 7. A channel 16 is provided in the middle part of the gate body 6.
[0021] The outer walls of gear 11 and gear 2 12 mesh with each other, and a connecting piece 9 is provided between the surfaces of gear 11 and gear 2 12.
