Detailed description of the invention
Fig. 1,2,3 show the structure chart of a kind of novel river flow water turbine.In figure, this novel Chuan Liushishuilunjibao
Including wheel mechanism, mainshaft mechanism and supporting mechanism, wheel mechanism uses 2 water wheels unit to combine, and water wheels unit includes two
End be provided with the center drum 12 of adpting flange 12a and Height Adjustable blade mechanism, blade mechanism comprise pole 2, brace 3,
Bottom bar 11 and blade 1, blade 1 is fixed on the framework being made up of 2, brace 3 of two poles and bottom bar 11, two
In two fixing pipes 13 that pole 2 uses adjustable structure to be inserted and secured on center drum 12, and regulate bolt with pole
20 fix, the most uniform 18 blade mechanisms of center drum 12, and 2 water wheels unit use bolt adjacent water wheels unit
Adpting flange 12a connects into a wheel mechanism, and on wheel mechanism, the top of each adjacent blades 1 arranges a push rod 4.Main shaft
Mechanism includes 6, two the first axillares 9 of 5, two bearing blocks of two main shafts and two the second axillare 9a, each in the both sides of bearing block 6
Being provided with a bearing block chute 6a, each main shaft 5 supported by bearing block 6 is fixing to be connected by bolt and connects the second axillare 9a's
First axillare 9.Supporting mechanism includes two supports 7 and two bases 8, and support 7 uses two vertical rod 7a and two oblique fulcrum bar 7b
Being fixed on panel 7c, the upper end of support 7 is provided with support slideway 19, is provided with two rows and slides return pulley 14 below the panel 7c of support 7,
Base 8 is provided with two the slideway 8a matched with the return pulley 14 that slides.Slip return pulley below the panel 7c of supporting mechanism 14
Fall on the slideway 8a of base 8, and use fixed mechanism that support 7 and base 8 are fixed together.The bearing of bearing block 6 both sides
Seat chute 6a is enclosed within respective support slideway 19, and uses bearing block bolt 10 to fix.Second axillare 9a of mainshaft mechanism adopts
It is connected with the adpting flange 12a at wheel mechanism two ends.The pole 2 of wheel mechanism, brace 3, push rod 4 and bottom bar 11 use square
Shape steel pipe.The blade 1 of wheel mechanism uses the rigid blade of rectangle.
Use above-mentioned technical scheme:
1, wheel mechanism (as shown in Fig. 1,2,3,6): when the river depth of water at hydraulic turbine work place shoals, current contact blade
Area reduce, the hydraulic turbine output moment of torsion reduce, cause hydraulic turbine energy conversion efficiency to reduce.In order to solve this problem, water wheels
Mechanism is made up of water wheels unit；Water wheels unit is assembled formed by pole 2, fixing pipe 13, center drum 12, blade 1；By pole 2,
A linkage of brace 3, bottom bar 11 splicing composition blade, installs blade 1 on a linkage and forms blade mechanism.By center circle
On cylinder 12, circumferentially pole 2, to fixing pipe 13, is inserted in fixing pipe 13, pole 2 is slided into according to water level by uniform welding 18
Appropriate location in fixing pipe 13, is fixed the pole 2 position (as shown in Figure 6) in fixing pipe 13 by pole regulation bolt 20,
Installing a push rod 4 on all poles of wheel mechanism, be connected with blade 1 by push rod 4, align the leaf on all wheel mechanisms
Sheet 1, completes the assembling of wheel mechanism.During design blade fixing device, use the side that pole 2 is slidably matched in fixing pipe 13
Formula, to realize the radical length increasing of the hydraulic turbine, increases turbine hydraulic energy conversion efficiency.And by increasing water wheels unit
Number is to increase the width of the hydraulic turbine, thus increases the area of hydraulic turbine contact river, produces bigger power, effectively utilizes river
Water energy is changed, and improves the utilization ratio of water resource；This invention not only meets hydraulic turbine stability requirement, and can improve water
The adaptation ability of turbine.
2, mainshaft mechanism (as shown in Fig. 1,2,7,8): flow water turbine common main shaft form in river is to pass through with a thin axle
Wearing the whole hydraulic turbine, this form main shaft must coordinate realization with aixs cylinder.Impeller presents radioactivity distribution, causes the hydraulic turbine overall
Structure is complicated, too fat to move, installation, maintenance is inconvenient, and concentrated stress that base bearing is subject to and moment of flexure are relatively big, to the safe operation of the hydraulic turbine not
Profit.For this problem, the mainshaft mechanism of the present invention is by main shaft 5, bearing block 6, base bearing 6b, first axillare the 9, second axillare 9a
Composition, composition form is that main shaft is welded on the first axillare 9, and the first axillare 9 is fixed on the second axillare 9a by bolt and nut,
Main shaft 5 is installed in bearing block 6 by base bearing 6b, completes the installation of mainshaft mechanism.By the wheel mechanism formed and main shaft machine
Structure assembles, and assembling mode is that the second axillare 9a is connected by bolt and nut with adpting flange 12a, completes wheel mechanism and main shaft machine
The assembling of structure.The mode using center drum 12 replacement main shaft assembles the hydraulic turbine, at water wheels two ends by the second axillare and main shaft
Overlap joint realizes the normal rotation of the hydraulic turbine.This version can either meet the requirement of hydraulic turbine intensity, it is also possible to shortens leaf
The length of sheet pole, and install simple, it is simple to safeguard.
3, supporting mechanism (as shown in Fig. 1,2,4,5): water jet propulsion water wheels rotate to be needed to carry out work with water wheels support
Make；Supporting mechanism is made up of support 7, slip return pulley 14, return pulley axle 15, fixed plate 16, base 8；Wheel mechanism carries out water wheels water
During wheel unit plus-minus, water wheels overall width changes, and causing water wheels to support needs to coordinate water wheels to change and change；Ask for solving this
Topic, is fixed to slip return pulley 14 in the concave groove of support 7 by return pulley axle 15 and axle nut 18；By fixed plate 16 by solid
Determine bolt 17 to be fixed on the T-shaped slideway of base.It is connected with support 7 by being fixed to ground base 8, its fit system master
The T-slot of base 8 to be passed through coordinates with the concave groove of support 7, determines support position on base plate according to water wheels partial width,
Fixed by return pulley fixed plate 16, complete supporting mechanism and assemble, supporting mechanism changes on transverse width be by slip return pulley and
Base engagement realizes, and when increasing a water wheels unit, both sides water wheels support and slide in and out distance respectively is 1/2 water wheels unit width
Degree.This mode facilitates water wheels and laterally expands, and is also prevented from overall hydraulic turbine play up and down.
4, wheel mechanism and mainshaft mechanism assemble: assembling form is the outermost of the second axillare 9a and adpting flange 12a of align
Edge screw, is fixed by bolt and nut, completes mainshaft mechanism and the assembling of a wheel mechanism.
5, mainshaft mechanism assembles with supporting mechanism: be installed on support slideway 19 by bearing block 6, according to pole 2 fixing
Position in pipe 13 determines the bearing block 6 position on support slideway 19, bearing block bolt 10 fix, and completes the peace of bearing block
Dress.When the hydraulic turbine carries out radial expansion, bearing block hydrous water turbine radius change, pole 2 slides up and down to realize water wheels
Machine normally rotates, and radial extent bearing block 6 upward sliding, radially shortening bearing block 6 slide downward, blade slippage is stretched with blade
Contracting amount is equal in magnitude, for solving this problem, is matched with support slideway 19 by bearing block chute 6a.
