Fig. 3 is that shown in Fig. 2, multiple runner 4 is connected on the structural representation on main shaft 2.
Embodiment
Refer to and consult Fig. 1 and Fig. 2 simultaneously, Fig. 1 is the plan view of the utility model direct current double click type horizontal shaft water-turbine embodiment; Fig. 2 is the plan view of the utility model direct current double click type horizontal shaft water-turbine embodiment.This direct current double click type horizontal shaft water-turbine, comprises engine housing 1, main shaft 2, speed increaser 3, runner 4 and speed regulator.The both sides of described engine housing 1 are respectively equipped with intake tunnel 11 and exhalant canal 12, described main shaft 2 be arranged on engine housing 1 center and between intake tunnel 11 and exhalant canal 12, and intake tunnel 11 and exhalant canal 12 are all vertical with main shaft 2, make water (flow) direction vertical with main shaft.Described main shaft 2 lower end is connected with underwater foundation 7 by lower bearing 6, and upper end is connected with the input shaft of coupling (not shown) with speed increaser 3 by upper bearing (metal) 8, and the output shaft of described speed increaser 3 is connected with generator and drive electrical generators generates electricity.Described runner 4 is arranged on described main shaft 2; Described speed regulator arrange engine housing 1 inner side surface and between described runner 4 and engine housing 1.
Described runner 4 comprises multiple blade 41 and at least two rotating disks 42.Described multiple blade 41 to be arranged on rotating disk 42 and circular array distribution, and described rotating disk 42 is arranged on main shaft 2 and the radial direction of described rotating disk 42 is vertical with described main shaft 2.Described blade 41 is curved plate, and the outer side of this blade 41 is parallel with described main shaft 2.Flowing water flows into and impacts blade 41 in intake tunnel 11, and blade 41 rotates, and drive main shaft 2 to rotate, rotating disk 42 is arranged on main shaft, can strengthen the dynamic stability of runner 4 entirety.When flowing water flows to exhalant canal 12 from roller centre, second time impact blades 41, drives main shaft 2 to rotate, increases rotational energy, improve generating efficiency.According to flow and flow velocity, the area of blade 41 can be changed, as the slow flowing water environment of the little flow velocity of flow, the blade 41 that area is little can be adopted, ensure the rotational efficienty of runner 4; For the flowing water environment that the large flow velocity of flow is fast, the blade 41 that area is large can be adopted, ensure the intensity of blade 41, increase generating efficiency.
In the present embodiment, described rotating disk 42 is provided with blade groove (not shown), and described blade 41 inserts in blade groove, and by steel plate pad and rotating disk 42 integral solder, improves intensity and the reliability of blade 41 further.
Described speed regulator comprises speed governing blade 51, speed governing axle (not shown) and two positive stops 52.Described speed governing blade 51 is arranged on the inner side surface of engine housing 1 and between runner 4 and engine housing 1, described speed governing axle is connected with described speed governing blade 51 and exposes to this engine housing 1, drives described speed governing blade 51 to rotate to the direction of runner 4 by regulating speed governing axle.Described two positive stops 52 to be arranged on engine housing 1 and to lay respectively at the two ends up and down of runner 4, the height of described speed governing blade 51 is greater than the height of runner 4, when speed governing blade 51 is close to runner 4, the positive stop 52 of upper and lower end will block the rotation of speed governing blade 51, prevents speed regulator blade 51 from encountering runner 4.When water velocity is slow, make the speed of runner 4 slow, when generating efficiency is lower, rotates speed governing axle and speed governing blade 51 is rotated toward runner 4 direction, block the Part way that flowing water impacts runner 4, be namely reduced by the discharge area of runner 4; Within a certain period of time, constant by the water flow of runner 4, cross-section area reduces, then water velocity will become greatly, when impacting runner 4, just can improve the rotating speed of runner 4, and then guarantee when water velocity is slow, the generating efficiency of water turbine still can remain in certain scope.
For guaranteeing the dynamic stability of water energy, described intake tunnel 11 rectangular in cross-section, and passage narrows from outside to inside gradually, guides current to rush at runner 4 according to several angle.In addition, the conduit wall of intake tunnel 11 described in the present embodiment and exhalant canal 12 is made up of steel plate.
For reducing the water loss of energy, improving turbine efficiency, between described intake tunnel 11 and runner 4, being provided with gap 9.
Refer to Fig. 3, it is that shown in Fig. 2, multiple runner 4 is connected on the structural representation on main shaft 2.For adapting to the riverbed of different depth, the utility model determines the runner number of connecting according to flow depth, can be arranged in series multiple runner 4 on same main shaft 1, drives electrical power generators, improves generating efficiency further.
When flowing water enters the center of runner 4 along the direction perpendicular to main shaft 2 by intake tunnel 11, impact blade 41, blade 41 rotates, and drives main shaft 2 to rotate, and realizes first time transformation of energy.When flowing water flows to exhalant canal 12 from the center of runner 4, will carry out Secondary Shocks again to blade 41, second time drives main shaft 2 to rotate, and realizes second time transformation of energy.When water flow and velocity variations, for ensureing that generating efficiency is unlikely to larger change occurs, rotatable speed governing axle 51, described speed governing blade 51 is driven to rotate around speed governing axle, control flow check water flows through the cross-section area of runner 4, guarantee that the rotational velocity of runner 4 keeps within the specific limits, realize stable generating efficiency.
Direct current double click type vertical shaft of the present utility model, by being integrally provided on rotating disk by multiple arc shaped blade, improve blade and holding load-carrying ability and reliability; Rotating disk is arranged on main shaft, strengthens the dynamic stability of runner entirety, improve generating efficiency.Further, by speed regulator regulating rotary wheel speed, runner speed is kept within the specific limits, realizes stable generating efficiency.Direct current double click type vertical shaft of the present utility model can according to the generated output of flow, flow velocity quantitative design 30-100000KW scope, can build be installed on rivers torrent, the mouth of a gorge, sea tide, existing water power plant downstream part, any valuable developable waters such as different flow, different drop heads can be adapted to.And do not need to build dam, structure is simple, and little investment cost is low; little to environmetal impact, maintenance protection is convenient, long service life; generating efficiency high (maximal efficiency can reach 80%) is the device solving environmental protection problem most value of exploiting and utilizing in hydroelectric project.
The utility model is not limited to above-mentioned mode of execution, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
