Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the present invention are described in detail:
Embodiment 1: a kind of reservoir normal-temperature water crosses dam system, sees Fig. 1-Fig. 3, including: mullion 1, water inlet buoy 2, smooth water flow's pipe 3, go out water float 4, water delivery vertical tube 10 and have the room temperature hole 8 etc. of certain slope.
Specifically, in dam body 5, set up one or more room temperature holes 8 with certain slope, for exporting top layer, the reservoir area normal-temperature water that this system is transferred.Gradient i in room temperature hole 8 should be identical with this table hole 6, dam gradient, to reduce the loss of flood peak during water delivery.Depending on the elevation in room temperature hole 8 should be according to this dead water level, to ensure more efficiently to transfer top layer, reservoir area normal-temperature water.Set up the size in room temperature hole 8 and number should be according to the concrete condition of reservoir and dispatching requirement depending on.
Groove 11 is set at each dam body 5 upstream side setting up room temperature hole 8 correspondence, to ensure the stability of the water delivery vertical tube 10 being connected in being placed in groove 11 with room temperature hole 8.The water delivery vertical tube 10 arranged in groove 11, the lower end of water delivery vertical tube 10 is connected with room temperature hole 8, and the upper end of water delivery vertical tube 10 is mounted with out water float 4.Going out water float 4 to keep afloat, can be freely lifted with the lifting of reservoir water level, water delivery vertical tube 10 freely can stretch with the lifting going out water float 4.Groove 11 can retrain water delivery vertical tube 10 makes it be only capable of ramping up and to descending motion.
Reservoir area, upstream 13 arranges mullion 1 away from the suitable distance of dam body 5, and mullion 1 is corresponding with room temperature hole 8.With ensure to dispose thereon can following water-level lifting and the water inlet buoy 2 that is freely lifted rises and only up to descending motion.The water inlet buoy 2 being placed on mullion 1 swims in the water surface all the time, can be freely lifted along mullion 1 with the lifting of reservoir water level, with ensure flow into this system be top layer, reservoir area normal-temperature water.Water inlet buoy 2 and go out to arrange between water float 4 smooth water flow's pipe 3 with connect both, smooth water flow's pipe 3 is also kept afloat, and is freely lifted with the lifting of two buoys, three all the time at same plane thus play the effect of stationary flow.Water inlet buoy 2, smooth water flow's pipe 3, the water delivery vertical tube 10 that goes out water float 4 and retractable ensure that top layer, reservoir area normal-temperature water is transferred by this system.
Described water delivery vertical tube 10 is the telescoping tube sealing socket, or is Serpentis abdomen flexible pipe, or is spiral coil.
This reservoir normal-temperature water crosses dam system, after being obtained top layer, reservoir area normal-temperature water by the water inlet buoy 2 lifted with reservoir water level and be freely lifted, after smooth water flow's pipe 3 stationary flow through keeping afloat, by going out in the water delivery vertical tube 10 that water float 4 flows into retractable with water inlet buoy 2 and steady water flow pipes 3 at same water level, and then flow out by having the room temperature hole 8 of certain slope, it is achieved that scheduling reservoir surface normal-temperature water crosses dam.
Embodiment 2: another kind of reservoir normal-temperature water crosses dam system, sees Fig. 1 and Fig. 4, is only on the basis of embodiment 1, improves water delivery vertical tube 10, supplement embodiment as one.This embodiment uses a kind of automatic pipe winding device, for realizing stretching or the contraction of water delivery vertical tube 10.This automatic pipe winding device includes support 14 and around socket 17, is installed on the support 14 by pipe axle and bearing around socket 17 two ends, such that it is able to freely rotatable.Water delivery vertical tube 10 can be wrapped on socket 17 for flexible pipe, can arrange groove to mate with water delivery vertical tube outside socket 17.Wherein, one end of water delivery vertical tube is upwards fixed on water buoy, and the other end connects with central siphon 15, and is provided with sleeve pipe 16 outside this side shaft pipe 15, and room temperature hole entrance is connected a guiding tube 18, and guiding tube 18 seals and is fixed on described sleeve pipe 16.Thus, when pulling up water delivery vertical tube, can rotate around socket 17.Low force torsion spring can also be installed on socket 17, it is achieved around socket 17 automatic reduction.
