Problems solved by technology

The water flowing down from the deep bottom of the reservoir is cooler in summer than the downstream rivers, so it is easy to cause chilling damage to crops or cold diseases in animals when used for irrigation; in winter, the water temperature is higher than the downstream rivers, which is not conducive to freezing and killing some pest eggs.
The frequent regulation of the reservoir (compared with natural lakes) results in frequent changes in the water temperature of the downstream river, and the temperature difference is too large, which seriously affects the growth and reproduction of organisms in the river downstream of the dam, especially fish.

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...

Abstract

The invention discloses a normal temperature water dam-passing system for a reservoir; by obtaining normal temperature water on a surface layer of a reservoir area from a water inflow buoy capable of rising and falling freely with a rise and a fall of a water level in the reservoir area, stabilizing water flow by a water flow stabilizing pipe floating in water, flowing the water into a water delivery vertical pipe capable of being stretched out and drawn back freely from a water outflow buoy located on the same water level with the water inflow buoy and the water flow stabilizing pipe, and then flowing the water out via a normal temperature hole having a certain gradient, the normal temperature water on the surface layer of the reservoir area is diverted to pass the dam. According to the normal temperature water dam-passing system disclosed by the invention, the normal temperature water of the reservoir is diverted and utilized and can be directly used for agricultural irrigation, fishery breeding and the like without increasing water temperature by sunning, thereby realizing the ecological diversion. Furthermore, the system, only by opening and closing of a gate, can realize diverting the normal temperature water on the surface layer of the reservoir area freely; the normal temperature water dam-passing system not only is convenient for intelligent management, but also realizes energy conservation and environmental protection; the system has obvious advantages of energy conservation, ecology, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of reservoir dam regulation and diversion, and in particular relates to an automatic regulation system for normal-temperature water passing through a dam in a reservoir. Background technique [0002] The construction of reservoir dams has changed the distribution of water volume in the basin and the water level of tidal river sections, causing gradient changes in reservoir water temperature along the direction of the river and in the direction of water depth. The water flowing down from the deep bottom of the reservoir is cooler in summer than the downstream rivers, so it is easy to cause chilling damage to crops or animal cold disease when used for irrigation; in winter, the water temperature is higher than the downstream rivers, which is not conducive to freezing and killing some pest eggs. The frequent adjustment of the reservoir (compared with natural lakes) results in frequent changes in the water tempe...
