Four, below in conjunction with drawings and Examples, further illustrate the present invention
Fig. 1 is marine reservoir schematic diagram; Fig. 2 is marine cooling tube;
Fig. 3 is water transfer pipeline schematic diagram; Fig. 4 is the intake pipe schematic diagram;
Fig. 5 is the communicating pipe schematic diagram; Fig. 6 is the sheet-metal duct sectional view;
Fig. 7 is steel cable and pipeline connection diagram.
Fig. 1, the marine reservoir 2 that has plastics film 3 to surround in sea 1, be used for splendid attire fresh water, floats on the surface.The thickness of plastic film 3 can be more than 1 millimeter, but matcoveredn inside and outside.
Fig. 2, have cooling tube 4 in sea 1, heat steam enters cooling tube 4, and the Cooling capacity exchanging energy with in seawater, be cooled to fresh water.Large marine cooling tube variable position, shift to cold water area.
Fig. 3, the estuario in river 7 has shoreline 6, away between the city 5 in river and river 7, there being pipeline 8 along the coastlines to lay, the fresh water in river 7 is delivered to city 5.Due to law of connected vessels, siphon principle, city 5 will be from obtaining the water with river 7 same sea level elevations pipeline 8.Perhaps conversely, 5 gather sea ice in city, dissolve Cheng Shuihou and deliver to pipeline 8 along the coastlines 6 place that needs fresh water.Or, set up large-scale piping manifold, as power network, the abundance of water district supplies water to piping manifold, and fetch water from piping manifold in water deficient regions, and piping manifold, with measuring apparatus, is taken, is charged according to the amount that supplies water, fetches water.Such as between Shanghai-Tianjin, just setting up such shoreline piping manifold, two places and the surplus and deficiency of helping mutually on the way.
Fig. 4, have pipeline 9 between 11Yu river, pond 7, and pipeline 9 can utilize law of connected vessels, siphon principle, and the water in river 7 is attracted to pond to 11 li, draws for water lift pipe 10.Water pipe 9 also can be imbedded underground, submerges under water, under mud.As long as the water surface in pond, lower than river, will have water endlessly to flow in pond from effluent stream in pipeline.As long as the highest point of pipeline 9 be no more than the vacuum barometric point the limit---13 meters left and right, the water in water pipe just can flow through.Many waterworkss are from fetching water with open channel in river, and open channel easily deposits, maintenance cost is high, can solve with siphon pipe.Namely there is this class example in Wuhan water factory.Also has Shanghai, though near the Changjiang river, lack of water.Owing to extracting underground well water, cause land subsidence.As adopt the present invention, Yangtze River Water is introduced to Shanghai with pipeline, just infinite water source is arranged.As long as the water outlet in Shanghai lower than or equal the sea level elevation in the Changjiang river.The water that pipeline attracts, can have multiple use, drinks such as after reprocessing, supplying, and the industrial or agricultural water, improve fluvial-environment etc.
Fig. 5, the water at water source 12 flows to duct end 19 from pipeline 13, the elevation of water surface at duct end 19 places and water source 12 sustained heights, dotted line means sustained height.The length of described pipeline can be more than 100 kilometers.To between Shanghai, the cross current with reaching the hundreds of kilometer, can obtain the water with the same sea level elevation of Three Gorges Reservoir in Shanghai such as Three Gorges Reservoir.At least, in the place lower than the Three Gorges Reservoir horizontal plane, can there are flowing out, can be pipeline on the way these places from water distribution manifold.Also stream is " herringbone " to pipeline along the river, " non-" font is laid.Namely be from upstream to downstream, in all sea level elevations, reach the section of diversion condition; From the two sides, river to the water deficient regions diversion, can utilize in a larger amount so the natural potential of natural water source or water continuously.Also the conduit pipe in different rivers, waters can be communicated with, form by " large pipeline net " surplus and deficiency of helping mutually.Described pipeline can have intermittently, and interrupted vial road is ended, and allows current out, then with the water that pipeline will flow out, continues to see off again.Can repeatedly utilize barometric point like this, by vacuum height on hydraulic pressure, be convenient to water lift.
Fig. 6, the cross section of sheet-metal duct 15 shows overlapping expansion joint 16, also has shell 14, the radial pressure in arrow means to manage.When pressure was excessive, sheet-metal duct can open expansion joint, and pressure is passed to shell, and shell is also scalable, with outside weight, as backfill soil extruding, offset pressure.Or self has elasticity sheet-metal duct, can when pressure increases, pressure be passed to shell, and self can not crushed.This pipeline allows to leak, as long as amount is little.
Fig. 7, pipeline 18 are with wirerope 17, and when pipeline was subject to longitudinal pulling force, wirerope will overcome this pulling force.Pipeline self also can have certain retractility, can change with steel cable.Such as pipeline is arranged in river, be subject to the transverse impact of current, produce the longitudinal pulling force to pipeline, at this moment, steel cable just can overcome this pulling force, and pipeline is fixed.Steel cable is reinforcing bar, steel pipe, nylon rope also.Described wirerope can be positioned at pipeline.
