[0018] Figure 1 The utility model is a schematic structural diagram of a manually rotatable rainwater grate device. DETAILED DESCRIPTION
[0019] The following is combined with Figure 1 The utility model is further described in detail with specific implementations to facilitate a clear understanding of the utility model, but they do not constitute a limitation on the utility model.
[0020] As attached Figure 1 As shown, a manually rotatable rainwater grate device of this embodiment includes a fixed bracket 1, a grate body 2, a rotating shaft 3 and a bracket base 9. The fixed bracket 1 is arranged on the bracket base 9 and a drainage hole is formed by enclosing a thick steel plate. The grate body 2 is made of cast iron and is arranged on the inner side of the top of the fixed bracket 1. It is a cone shape with a large top and a small bottom. The strip openings 4 on the grate body 2 are parallel and spaced apart, and the cross section of the strip openings 4 is an isosceles trapezoid with a large bottom and a small top.
[0021] The inner side of the top of the fixing bracket 1 is closed to form a slot 6 for bearing and fixing the grate body 2. L-shaped rotating shaft mounting holes 5 are symmetrically arranged on the two side surfaces at one end of the grate body 2. A steel plate thickening portion corresponding to the L-shaped rotating shaft mounting hole 5 is arranged on the fixing bracket 1, and a fixing bracket mounting hole 7 is reserved on the steel plate thickening portion for fixing the rotating shaft 3. The rotating shaft 3 is made of stainless steel and passes through the L-shaped rotating shaft mounting hole 5 and the fixing bracket mounting hole 7, so as to fix the grate body 2 on the fixing bracket 1.
