Connecting flange 12a connects into a wheel mechanism, and a mandril 4 is arranged in the top of each adjacent blades 1 on wheel mechanism.Main shaft
Mechanism includes two the first axillares 9 of 5, two, main shaft bearing block 6, two and two the second axillare 9a, each in the both sides of bearing block 6
If there are one bearing block sliding slot 6a, the main shaft 5 each supported by bearing block 6 is fixedly connected with the first axillare 9, and the first axillare 9 uses
It is bolted the second axillare 9a.Supporting mechanism includes two holders 7 and two pedestals 8, and holder 7 uses two upright bar 7a and two
Oblique fulcrum bar 7b is fixed on panel 7c, and the upper end of holder 7 is equipped with holder slideway 19, is equipped with below the panel 7c of holder 7 two rows of sliding
Dynamic return pulley 14, pedestal 8 are equipped with and sliding 14 matched two slideway 8a of return pulley.Sliding below the panel 7c of supporting mechanism
Return pulley 14 is located on the slideway 8a of pedestal 8, and holder 7 and pedestal 8 are fixed together using fixed mechanism.6 liang of bearing block
The bearing block sliding slot 6a of side is sleeved on respective holder slideway 19, and is fixed using bearing block bolt 10.The second of mainshaft mechanism
Axillare 9a is connected by screw bolts the connecting flange 12a at wheel mechanism both ends.Strut 2, brace 3, mandril 4 and the bottom of wheel mechanism
Bar 11 uses rectangular steel pipe.The blade 1 of wheel mechanism uses the rigid blade of rectangle.
Using above-mentioned technical solution：
1, wheel mechanism（As shown in Fig. 1,2,3,6）：When the river water depth of water where hydraulic turbine work shoals, flow contact
The area of blade is reduced, and hydraulic turbine output torque reduces, and leads to the reduction of hydraulic turbine energy conversion efficiency.In order to solve this problem,
Wheel mechanism is made of water wheels unit；Water wheels unit is formed by strut 2, fixing pipe 13, center drum 12, the assembling of blade 1；It will branch
The branch linkage of bar 2, brace 3, the splicing composition blade of bottom bar 11, installs the formation blade mechanism of blade 1 in branch linkage.Will in
12 upper edge even circumferential of heart cylinder welds 18 pairs of fixing pipes 13, and strut 2 is inserted into fixing pipe 13, is slided strut 2 according to water level
Appropriate location in fixing pipe 13 is moved, position of the strut 2 in fixing pipe 13 is fixed by strut adjusting bolt 20（Such as Fig. 6 institutes
Show）, a mandril 4 is installed on all struts of wheel mechanism, mandril 4 is connected with blade 1, is aligned on all wheel mechanisms
Blade 1, complete the assembling of wheel mechanism.When designing blade fixing device, it is slidably matched in fixing pipe 13 using strut 2
Mode increases turbine hydraulic energy conversion efficiency to realize that the radical length of the hydraulic turbine increases.And by increasing water wheels list
First number, to increase the area that the hydraulic turbine contacts river water, generates the power of bigger, efficiently uses to increase the width of the hydraulic turbine
River water energy is converted, and the utilization ratio of water resource is improved；The invention not only meets hydraulic turbine stability requirement, but also can improve
The adaptability of the hydraulic turbine.
2, mainshaft mechanism（As shown in Fig. 1,2,7,8）：Flow water turbine common main shaft form in river is passed through with one thin axis
The entire hydraulic turbine is worn, this form main shaft must coordinate with aixs cylinder to be realized.Radiativity distribution is presented in impeller, causes the hydraulic turbine whole
It is complicated, too fat to move, installation, maintenance is inconvenient, the concentrated stress and moment of flexure that base bearing is received are larger, not to the safe operation of the hydraulic turbine
Profit.For this problem, mainshaft mechanism of the invention is by main shaft 5, bearing block 6, base bearing 6b, the first axillare 9, the second axillare 9a
Composition, composition form are that main shaft is welded on the first axillare 9, and the first axillare 9 is fixed to by bolt and nut on the second axillare 9a,
Main shaft 5 is installed to by base bearing 6b in bearing block 6, and the installation of mainshaft mechanism is completed.By the wheel mechanism of formation and main shaft machine
Structure assembles, and assembling mode is that the second axillare 9a is connect with connecting flange 12a by bolt and nut, completes wheel mechanism and main shaft machine
The assembling of structure.The hydraulic turbine is assembled in such a way that center drum 12 replaces main shaft, passes through the second axillare and main shaft at water wheels both ends
Overlap joint realizes the normal rotation of the hydraulic turbine.This structure type can either meet the requirement of hydraulic turbine intensity, can also shorten leaf
The length of piece strut, and install simply, convenient for safeguarding.
3, supporting mechanism（As shown in Fig. 1,2,4,5）：The rotation of water jet propulsion water wheels needs to carry out work with water wheels support
Make；Supporting mechanism is made of holder 7, sliding return pulley 14, return pulley axis 15, fixed plate 16, pedestal 8；Wheel mechanism carries out water wheels water
When wheel unit is added and subtracted, water wheels overall width changes, and water wheels support is caused to need that water wheels is coordinated to change and change；It is asked to solve this
Topic will be slided return pulley 14 and is fixed in the concave groove of holder 7 by return pulley axis 15 and axle nut 18；Fixed plate 16 is passed through solid
Bolt 17 is determined fixed on pedestal T-type slideway.By being connected with holder 7 fixed to the pedestal 8 on ground, fit system master
To be coordinated by the T-slot of pedestal 8 and the concave groove of holder 7, position of the holder on bottom plate determined according to water wheels partial width,
Fixed by return pulley fixed plate 16, complete supporting mechanism assembling, supporting mechanism changes on transverse width be by slide return pulley and
Base engagement is realized, when increasing a water wheels unit, it is that 1/2 water wheels unit is wide that water wheels support in both sides slides in and out distance respectively
Degree.This mode facilitates water wheels and carries out lateral expansion, is also prevented from whole hydraulic turbine play up and down.
4, wheel mechanism and mainshaft mechanism assemble：Assembling form is the outermost of alignment the second axillare 9a and connecting flange 12a
Edge screw hole, is fixed by bolt and nut, completes the assembling of mainshaft mechanism and branch wheel mechanism.
5, mainshaft mechanism and supporting mechanism assemble：Bearing block 6 is installed on holder slideway 19, according to strut 2 in fixation
Position of the location determination bearing block 6 on holder slideway 19 in pipe 13, is fixed by bearing block bolt 10, completes the peace of bearing block
Dress.When the hydraulic turbine carries out radial expansion, bearing block coordinates hydraulic turbine radius change, is slided up and down on strut 2 to realize water wheels
Machine normally rotates, and 6 upward sliding of radial extent bearing block, radial shortening 6 slide downward of bearing block, blade slippage are stretched with blade
Contracting amount is equal in magnitude, to solve the problems, such as this, is matched with holder slideway 19 by bearing block sliding slot 6a.
