DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] A number of embodiments are given below to describe the present invention in detail.

[0034] Example 1

[0035] like Figures 1 to 4 As shown, a smooth cylindrical hydroelectric power generation device, water from a cliff water source 1 fills a container 3, and a cylinder 4 rotates under the weight pressure of the water in the container 3, transmitting the water to a hydroelectric generator 10 to generate electricity;

[0036] And the understanding of the properties of water for this mechanism: the tension of water in container 3 is negligible, and the water has no displacement, because the weight of container 3 is vertical pressure and container 3 is solid.

[0037] Example 2

[0038] like Figure 5 As shown, the weight of water is vertical pressure, just like the iron rod 18, the upper end 20 of the iron rod 18 generates force on the radius 22, and the radius 22 has no displacement; the iron rod 18 is still in its original state; the water is internal, the container 3 is external, and the container 3 is a solid, so any solid is a vertical pressure.
