Embodiment
By reference to the accompanying drawings, embodiments of the invention are provided as follows:
As shown in Figure 1: the lock back of the body formula water-energy generating electricity station described in the present embodiment is primarily of water turbine 1, toothed belt transmission speed increaser 2, generator 3, sluice 6, turbine chamber 7, speed governing sluice 9 and station composition, and sluice 6 can be any one sluice of known device.Water intake is provided with in the bottom of sluice 6, and this water intake position is provided with speed governing sluice 9, what described speed governing sluice 9 adopted is " under water speed governing sluice (ZL201420012352.4) " patent that the present inventor has applied for, it is connected to (upstream face) before sluice 6, is slidably connected with sluice 6.Be connected with water turbine 1, toothed belt transmission speed increaser 2, generator 3 and station at sluice 6 back side (back side), described water turbine 1 is horizontally installed in station, pecks water mode for laterally pecking water.What adopt is " cavity shaftless water selflubricating water turbine (ZL201420012505.5) " patent that the present inventor has applied for.Described water turbine 1 is fixedly supported on bottom girder 5 lower end surface of station by manger board 4, namely the two side ends of water turbine 1 is connected with manger board 4 respectively, the upper end of manger board 4 is fixedly connected with the lower end surface of station bottom girder respectively, being fixedly connected with sluice 6 of station bottom girder 5.Toothed belt transmission speed increaser 2 and generator 3 are all fixed on the upper-end surface of station bottom girder 5, what described toothed belt transmission speed increaser 2 adopted is " toothed belt transmission speed increaser (ZL201420012329.5) " patent that the present inventor has applied for, and what generator 3 adopted is conventional generator.The input end of described toothed belt transmission speed increaser 2 is connected with the output terminal of water turbine 1, output terminal is connected with the input end of generator.The bottom of described turbine chamber 7 is positioned at below sluice 6, utilizes dyke construction, adopts concrete body construction to make.Directly dyke construction can be become the bottom of turbine chamber, also existing dykes and dams can be transformed into the bottom of turbine chamber, significantly can reduce construction cost thus, and easy to implement.Turbine chamber 7 comprises below station bottom girder 5, space above the bottom of turbine chamber and between sluice 6.The ground surface being positioned at water turbine 1 bottom bottom turbine chamber 7 has arc transiting surface that is downward and that border on riverbed, this arc transiting surface coincide with 1/4th cambered surfaces with water turbine girth.Effect is: when water turbine drops to this position along with sluice, can normally work, and forms S line generating power by water current pattern with the flowing water of crossing entered by sluice 6 water intake; When water turbine leaves this position along with sluice rises to, and form a word generating power by water current pattern by the flowing water of crossing entered between sluice 6 bottom and turbine chamber 7 upper-end surface.In addition, water turbine in rotary course, only have all the time 1/4th of girth with cross flowing water and contact and do work and produces power, part in addition does not then contact with flowing water excessively, rotates among air, and to peck water mode be laterally peck water.Thus, the dependence to hydraulic head pressure is reduced.The upper end being provided with station Wall body 10, station Wall body 10 in other three sides of station bottom girder 5 is connected with back timber, back timber is provided with safety barrier 11, in station, is also provided with working stand 8.
The present invention in use, has two kinds of working staties:
Fig. 2 A is depicted as and is applied to the generating of normality storage capacity waters: start speed governing sluice 9, open the water intake on sluice 6, cross the bucket that flowing water is advanced into water turbine 1 from the water intake edge of sluice 6, under the extruding of manger board 4 and turbine chamber 7, promotion water turbine rotates, form S line generating power by water current pattern, the kinetic energy that water turbine produces passes to toothed belt transmission speed increaser 2 input shaft, and the kinetic energy after speedup is reached generator 3 by output shaft and generates electricity by toothed belt transmission speed increaser.Flowing water of crossing after workmanship enters riverbed.
Fig. 2 B is depicted as the generating under flood control and SEA LEVEL VARIATION state: when water level rises, and starts speed governing sluice 9, closes the water intake on sluice 6, promotes sluice 6, makes speed governing sluice 9 rise to a line generating water level with sluice 6 simultaneously.At this moment the bucket blade of flowing water from impulse water turbine 1 direct between sluice 6 bottom and turbine chamber 7 upper-end surface is crossed, promote water turbine to rotate and continuous rotation, the kinetic energy of generation is passed to the input shaft of toothed belt transmission speed increaser 2, the kinetic energy after speedup is reached generator 3 by output shaft and implements generating by toothed belt transmission speed increaser.Flowing water of crossing after workmanship enters riverbed.
When the water level descends, control sluice 6 by elevating system to generate electricity at a line water level all the time.When a line water level and the riverbed water level water surface close to time, start speed governing sluice 9, close the water intake on sluice 6, decline sluice 6, is converted to S line generating power by water current pattern, and so circulation generates electricity.
