Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] Figure 1 to Figure 5 It is a structural schematic diagram of a crank arm steel dam gate. As can be seen from the figure, it includes a steel dam door leaf 3 installed between the two left side walls 1 and right side wall 2, and the bottom of the steel dam door leaf 3 is connected with the dam body 5 through the bottom transverse shaft 4, and the steel dam The door leaf 3 swings around the bottom transverse axis 4 . When the steel dam door leaf 3 is swung up, the water can be blocked like figure 1 As shown, the hem achieves water release as figure 2 shown. The two ends of the steel dam door leaf 3 on the water-facing surface and the bottom transverse shaft 4 are welded with forward-extending curved arms 6 respectively, or the two ends of the steel dam door leaf 3 on the upstream-facing surface are respectively welded with forward-ex...
