Embodiment 1
[0015] Embodiment 1: a kind of reservoir normal temperature water dam crossing system, see Figure 1-Figure 3 , including: vertical column 1, water inlet buoy 2, smooth water flow pipe 3, water outlet buoy 4, water delivery vertical pipe 10 and normal temperature hole 8 with a certain slope.
[0016] Specifically, one or more normal temperature holes 8 with a certain slope are added in the dam body 5 to output the normal temperature water on the surface of the reservoir area drawn by the system. The slope i of the normal temperature hole 8 should be the same as the slope of the dam surface hole 6, so as to reduce the head loss in the water delivery process. The elevation of the normal temperature hole 8 should be determined according to the dead water level of the reservoir, so as to ensure that the surface layer normal temperature water in the reservoir area can be transferred more effectively. The size and number of additional normal temperature holes 8 should be determined...
Embodiment 2
[0021] Embodiment 2: another kind of reservoir normal temperature water dam system, see figure 1 and Figure 4 , only on the basis of Embodiment 1, the water transfer riser 10 is improved, as a supplementary implementation. This embodiment adopts an automatic pipe winding device for stretching or shrinking the water transfer riser 10 . The automatic pipe winding device includes a support 14 and a winding tube 17, and the two ends of the winding tube 17 are installed on the support 14 through a tube shaft and bearings, so that they can rotate freely. The water delivery standpipe 10 is a flexible tube that can be wound on the winding tube 17, and grooves can be arranged on the outside of the winding tube 17 so as to match the water delivery standpipe. Wherein, one end of the water transfer vertical pipe is fixed upward on the water inlet buoy, and the other end communicates with the shaft pipe 15, and a sleeve pipe 16 is arranged outside the side shaft pipe 15, and a guide pip...
