Description
Technical field
The present invention is a kind of method that utilizes water for producing electric power and device, refers in particular to a kind of hydroelectric method of advection and device of utilizing, and is mainly used in the hydroelectric power of small-sized current.
Background technique
The distribution of China's hydraulic power potentials and development and use China thereof are vast in territory, and the river is numerous, and total length reaches km more than 420,000, and drainage area is at 100km
2Above river just has more than 5000, also has dotted lake; Water energy reserves are very abundant, and only the rivers and creeks hydraulic power potentials estimates just be 6.76 hundred million kW, occupies first place in the world.The capacity that may develop is about 3.79 hundred million kW, and annual electricity generating capacity is about 1.9 trillion kWh, and every year is 1583kW.h (by 1,200,000,000 populations) per capita.The policy that China develops power industry is: " suit measures to local conditions, extreme misery develops simultaneously, and priority development of hydropower is greatly developed thermoelectricity, suitably develops nuclear power." this policy meets China's actual conditions, to quickening China development of electric power industry, especially preferential development water power, accelerating construction of hydropower facilities and will play crucial effect.The principal mode that water can utilize is to utilize water can produce electric energy.The water power plant is to be the development and use hydraulic power potentialss, water can be transformed into electric energy and the synthesis of the engineering works built and machinery, electrical equipment, is to utilize water can produce the base of electric energy.Therefore, water can utilize and refer generally to hydroelectric power.But, hydroelectric power need be built a series of hydraulic structure and structure of hydropower station, the concentrated flow drop, form reservoir, control and guiding current can be transformed into water the mechanical energy of rotation by water turbine, driving generator by water turbine again rotates, thereby send electric energy, be sent to electric power system after process distribution and converting equipment boost then, resupply the user.Required cut-off dam making expense is huge, and engineering construction is subject to many limitations.
For further exploitation hydroelectric power, people are also considering how to utilize the water source generating of low head or advection water.Chinese patent literature (application number big 89102616.9, name is called " no drop (natural flows) hydraulic power generating method ") hydraulic power generating method that a kind of what is called need not have drop disclosed, be characterized in to build a dam the level of tail water is improved, but by under the manipulation of automatic control system, water wheels can rise with the rising of water level, descend to descending and utilize the dynamic power of natural flows, so it does not have the drop requirement to current.
Chinese patent literature (application number big 03261787.9, name is called " no drop hydroelectric generator water wheels ") a kind of hydroelectric no drop hydroelectric generator water wheels that are used for are disclosed, it has two torus that are oppositely arranged, two torus are through being oppositely arranged on the cross radius rod assembly center wheel shaft on the torus, be respectively arranged with the water resistance plate axis that is connected two torus at torus with the joint of cross radius rod, be respectively fitted with the water resistant plate that places between two torus on its each water resistance plate axis, be provided with water baffle rod with the corresponding cross radius rod of each water resistant plate phase configuration.By uniform four water resistant plates on the torus that wheel shaft is set at the center, utilize water resistant plate to the resistance of the current that flow and live axle rotates, be used to generator set that rotor rotation power is provided.
But above-mentioned patent is disclosed all is a kind of wheel mechanism the same with the drop power generating equipment is arranged, wheel mechanism is intake on one side by water wheels and is promoted the water turbine rotation, the rotating shaft of water turbine is perpendicular to the water surface, the shortcoming of this mode is that water turbine has only one side to be subjected to water hammer, and current are restricted in Vertical direction, thereby do not make that waterpower plays one's part to the full, especially for the situation of small water flow, just be difficult to make water turbine to drive generator for electricity generation.Necessaryly this is further studied improvement.
Summary of the invention
The objective of the invention is to the deficiency at existing no drop (natural flows) hydraulic power generating method and equipment, proposing a kind of hydraulic power potentials can more be given full play to, and efficient is higher, especially is fit to the hydraulic power generating method and the equipment of rill water generating.
The objective of the invention is to be achieved through the following technical solutions, a kind of novel method of non-drop height level power generating, adopt the hydroelectric power of no drop advection, by of the water turbine generating of a kind of shaft parallel in the roller type of the water surface, the rotating shaft and the wheel blade of water turbine are parallel to water surface arrangement, rotating shaft and wheel blade that the impact force of utilizing advection water to flow drives water turbine are parallel to water surface rotation, drive generator for electricity generation by water turbine again.
Device according to above-mentioned electricity-generating method is, a kind of advection hydroelectric generator comprises water turbine, generator, it is characterized in that: the rotating shaft of described water turbine is parallel to the water surface, and the impeller of water turbine is to rotate around the rotating shaft that is parallel to the water surface.The rotating shaft of water turbine is put down in the water surface, and has the impeller of half to be immersed in the current abreast, and will be when advection water flows, and impeller is around the rotating shaft rotation of water turbine under the effect of advection waterpower; Second half impeller then is higher than the water surface and does not contact with the water source.One end of water turbine rotating shaft is connected with accelerator, and accelerator then is connected with generator set again, and drives generator for electricity generation.
The present invention utilizes the impact of upstream advection current to turbine impeller, drives the rotation of water turbine central shaft, finishes by water to become mechanical energy.Owing to adopted the novel water wheels structure of the shaft parallel of water turbine in the water surface, then can effectively utilize impact force of water flow to generate electricity, do not utilize the pressure of drop to generate electricity and do not need to form again so-called drop.In fact be exactly to utilize ancient waterwheel principle to generate electricity, therefore have simple in structure, the sufficient characteristics of current utilization.
