Abstract
The utility model relates to a rivers generator screw. There is the increment in the current rivers generator screw of main solution and beats, and manufacturing cost is high to reach the buoyancy difference and influence the technical problem of generating efficiency. This screw includes the pivot, the axial of pivot is equipped with a plurality of impeller assemblies, each the impeller assembly includes blade seat, blade, it is peripheral and rotatory by its drive that the pivot is located to the blade seat cover, blade circumference distributes peripherally in the blade seat, the blade includes first blade part, second blade part, the mutual fixed connection in upper end separately of first blade part and second blade part, the looks of the lower extreme separately both sides of first blade part and second blade part are opened and the shape cavity. Because this rivers generator screw's blade adopts the hollow structure design, effectively reduce the weight of screw, manufacturing cost is reduced, and its buoyancy can be increased, help the better realization generating efficiency of rivers generator.
Description
Technical field
The utility model relates to a kind of hydroelectric field, refers in particular to a kind of water flow generator screw.
Background technology
Its operation principle of water flow generator is to drive the propeller blade of generator to rotate by current, and blade drives propeller rotational to convert mechanical energy into electric energy, then by cable transfer electric power.At present, the screw of water flow generator is solid construction, and is made up of metal material, and its weight is big, and material consumption is big, causes the buoyancy of screw to reduce, so that screw is the most painstaking when rotated, affects its generating efficiency.
Summary of the invention
In order to overcome shortcoming and the weak point of background technology, the utility model provides a kind of water flow generator screw, solves existing water flow generator screw and there is increment and beat, and manufacturing cost is high, and buoyancy difference and affect the technical problem of generating efficiency.
The technical solution of the utility model is: a kind of water flow generator screw, including rotating shaft, described rotating shaft be axially arranged with some impeller sets, each described impeller sets includes blade seat, blade, described blade seat is sheathed on rotating shaft periphery and is rotated by it, described blade is circumferentially distributed peripheral in blade seat, described blade includes the first blade part, the second blade part, the respective upper end of described first blade part and the second blade part is mutually permanently connected, and the phase both sides, respective lower end of the first blade part and the second blade part are opened wide and shaped hollow.
Be provided with support member in described cavity, described support member be connected inside blade and and cavity inner wall between there is certain gap.
The upper end of described support member fixes with the upper end of the first blade part, the second blade part, and lower end is fixing with the bottom of blade to be connected.
Described support member and the first blade part, the second blade part inwall between distance form gap.
It is provided with toroidal cavity in described blade seat.
Described rotating shaft is hollow-core construction.
The upper end of described first blade part and the second blade part is welded to each other and forms.
The utility model has the advantages thatOwing to the blade of this water flow generator screw uses hollow-core construction design, effectively reduce the weight of screw, reduce manufacturing cost, and its buoyancy can be increased, contribute to water flow generator and preferably realize generating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model Leaf.
In figure, rotating shaft 1, blade seat 2, blade 3, the first blade part 31, the second blade part 32, cavity 4, support member 5, gap 6, toroidal cavity 7.
Detailed description of the invention
Below for accompanying drawing, embodiment of the present utility model is described further:
As shown in the figure, a kind of water flow generator screw, including rotating shaft 1, described rotating shaft 1 be axially arranged with some impeller sets, each described impeller sets includes blade seat 2, blade 3, described blade seat 2 is sheathed on rotating shaft 1 periphery and is rotated by it, described blade 3 is circumferentially distributed peripheral in blade seat 2, described blade 3 includes first blade part the 31, second blade part 32, the respective upper end of described first blade part 31 and the second blade part 32 is mutually permanently connected, and the phase both sides, respective lower end of the first blade part 31 and the second blade part 32 are opened wide and shaped hollow 4.This blade is mutually combined is formed by the first blade part and the second blade part, the upper end of the first blade part and the second blade part is mutually permanently connected, lower end is open design and is connected with blade seat, cavity is formed between first blade and the second blade, so that blade forms hollow-core construction, described first blade part and the second blade part materials are few, according to such scheme, owing to the blade of this water flow generator screw uses hollow-core construction design, effectively reduce the weight of screw, reduce manufacturing cost, and its buoyancy can be increased, contribute to water flow generator and preferably realize generating efficiency.
In the utility model, in described cavity 4, be provided with support member 5, described support member 5 be connected inside blade 3 and and cavity inner wall between there is certain gap 6.By arranging support member in cavity, support member is connected with blade interior, and is placed in cavity, leave certain gap, on the one hand blade interior can be supported so that its intensity meets the requirements, on the other hand can reduce the materials of support member as best one can, reduce weight and reduce material.
In the utility model, the upper end of described support member fixes with the upper end of first blade part the 31, second blade part 32, and lower end is fixing with the bottom of blade 3 to be connected.The upper end of described first blade part 31 and the second blade part 32 is welded to each other and forms, and the distance between described support member 5 and the inwall of first blade part the 31, second blade part 32 forms described gap 6.The upper end of support member is connected with each other with this weld, and lower end is connected with blade bottom such that it is able to effectively support the entirety of blade, and the intensity of blade is effectively strengthened so that its when rotated, stability is strong, improves generating efficiency.
In the utility model, in described blade seat 2, it is provided with toroidal cavity 7.Blade seat 2, rotating shaft 1 all use hollow-core construction so that the overall weight of screw is effectively reduced, and reduce cost, strengthen its lightness.
Embodiment is not construed as the restriction to utility model, but any is made based on spirit of the present utility model
Improvement, all should be within protection domain of the present utility model.
