What Fig. 2 represented is the outside drawing that is built in the flexible nylon conduction dam of two sides, river.Wherein 1 is river, and 2 is dam body, and 3 is gate, and 4 are the flood discharge drainage pipe, and 5 are the extension dam, and 6 is basic dam, and 7 for being water inlet.The dykes and dams pedestal is buried in the underground, can't see.
As shown in Figure 3, the hydraulic pressure robot control system(RCS) comprises that the bottom, outer end inlaying the hydraulic pressure automatic control lever (3) of iron plate (4), hydraulic pressure automatic control ball float (15), circuit (8), power supply (6), circuit contact (5), alarm (7) and electromagnet (9).Hydraulic pressure automatic control lever is installed in the wall top, the outside on basic dam (2), iron plate is being inlayed in its bottom, outer end, hydraulic pressure automatic control ball float (15) is being fixed in the inner, the ball float of hydraulic pressure automatic control at ordinary times just in time is in the basic dam fixedly on the virtual warning line line (16) of water storage space, by circuit power supply, the circuit contact, the iron plate that is inlaying bottom, lever outer end, alarm and electromagnet couple together, the iron plate that is inlaying common circuit contact and bottom, lever outer end disconnects, when river rises to virtual warning line line, hydraulic pressure automatic control ball float is held up, hydraulic pressure automatic control lever outer end presses down, be embedded in the iron plate contact circuit contact of its underpart, closing of circuit, alarm equipment alarm, electromagnet produces induced field, the flood discharge drainage gate of top being inlayed iron plate attracts up, opens the flood discharge drainage channel.1 is extension dam dam body, and 10 are flood discharge drainage pipe interface, and 11 for being embedded in the iron plate on flood discharge drainage gate top, and 12 are flood discharge drainage gate, and 13 is the dykes and dams pedestal, and 14 is the passage between basic dam and the extension dam, and 17 is water inlet, and 18 is the river shoal, and 19 is river.
Flexible nylon conduction dam can " be sewed up " on the conventional dam of river, lake and reservoir, also can have dykes and dams of one's own.Each several part all is hollow and interconnects, can retaining, leak water and draining.The dam, basis is built on the both sides, river course or storehouse, lake periphery.The extension dam is folded on basic dam or the conventional dam at ordinary times.Basis dam and extension dam in the upstream, middle reaches just have inlet gate every a segment distance, suitable place, downstream has emptying gate, can be used for purposes such as field irrigation or generating.One of numerous flood discharge drainage pipe is connected with basic dam, and one is connected with river, lake and reservoir with shunting.At ordinary times, but also retaining of dam body is used as reservoir and river channel and is used.Flood one pours in dykes and dams, has just opened the various places gate automatically.When flood covers basic dam, just enter the extension dam.Flood rise, extension dam stop the excessive of flood at random also along with rise; Countless drainage pipes then draw flood toward shunting ground continually, become to intercept to dredging, thus the generation of avoiding or stopping big flood effectively.The drainage pipe of the Changjiang river water system dykes and dams preferably matches with Three Gorges and project of South-to-North water diversion, because flood season water level height, flow is big, is the south water to north condition of providing convenience.
Fig. 4, Fig. 5, Fig. 6 have reflected the operating principle that the flexible nylon conduction dam retaining is drained off floodwaters:
When river was plentiful in normal day, river can flow to the fixedly water storage space on basic dam by the countless water inlets of dykes and dams along the river, because the water surface does not arrive virtual warning line line, at this moment gate is (as shown in Figure 4) of closing.
Rainy day, river rose to virtual warning line line, and hydraulic pressure automatic control ball float is held up, and hydraulic pressure automatic control lever outer end presses down, and is embedded in the iron plate contact circuit contact of its underpart, closing of circuit, alarm equipment alarm; Electromagnet produces induced field, and the flood discharge drainage gate of top being inlayed iron plate attracts up, and flood discharge drainage pipe interface opens wide, and river begins to leak into the flood discharge drainage pipe, flows to reservoir, lake or other water channels (as shown in Figure 5).
During spate, flood covers basic dam, just enters the extension dam.Flood rise, extension dam stop the excessive of flood at random also along with rise; Countless drainage pipes then draw flood toward shunting ground continually, and basic dam, extension dam itself are also unblocked simultaneously, the rivers,lakes and seas that the flood that billows is guided into the downstream, thereby the generation (as shown in Figure 6) of avoiding or stopping big flood effectively.
Compare with conventional dam, the invention has the beneficial effects as follows:
In rainy season, rivers soared, change and intercept, flood is violently guided into the place of need water short of rain to dredging.Can be used as reservoir filling at ordinary times, the navigation of navigating can be done the water transport traffic, is again unique tourist sight.The irrigated farmland that then can discharge water dry season provides industrial water use.
Simple in structure, make easily, be convenient to supervision, for ease of maintenaince.The millions of easily up to ten million people of conventional dam hurry to the front of speedily carrying out rescue work, and flexible nylon conduction dam needs only several thousand people, several ten thousand people are just much of that; The hidden danger that the conventional dam a couple of days can not find, the dangerous situation of not arranging, flexible nylon conduction dam only needs several hrs just to solve.The human and material resources, financial resources and the labour intensity that alleviate able to resisting flood and drought can either be significantly reduced, also the cost of making dike, bank protection can be reduced significantly.
Though above-mentioned benefit is arranged, can not lose vigilance.Flexible nylon conduction dam also need to train one conscientious, professional technique maintenance troop really up to the mark day and night patrols, and sees that damage just repaiies, and meets Lou and just mends, and hidden danger is eliminated in bud.But, the number of maintenance troop significantly reduces than conventional dam, and labour intensity also reduces greatly.
