Abstract
The utility model discloses an impeller of a water turbine, which comprises a rotary disc body. A plurality of bowl-shaped blades are uniformly arranged on the outer edge of the rotary disc body, and a shaft hole is formed at the center of the rotary disc body. The impeller has simple structure. Since the bowl-shaped blades are adopted, rotational torque under countercurrent can be remarkably reduced, power of the water turbine is improved, and the water turbine can be used just with continuous water flow, without needing higher water flow and greater water head. Meanwhile, since twisted blades of the original water turbine are not used any more, the processing of blades becomes easy and the price of the water turbine is reduced.
Description
Technical field
The utility model relates to impeller, is specifically related to a kind of turbine impeller.
Background technique
In today of energy growing tension, utilize water resource to provide the water turbine of power more and more to be subject to people's attention, present water turbine is work like this, water turbine is made up of rotary impeller in housing and the housing, the impeller horizontal positioned, the blade on the impeller twists to same direction, utilizes higher drop and water flow to impact impeller then, make wheel rotation, thereby make water turbine have power.
Such technology has the following disadvantages: because traditional blade wheel structure, must have bigger water flow faster flow velocity provide impact force could promote the less wheel rotation of size, a large amount of water flows through outside the blade circumference or between the blade, and a large amount of waterpower is not fully used, also can produce the resistance effect that stagnates between the water molecule, influence the rotating speed of rotor, cause the waste of great lot of water resources; Thereby cause the place less in water flow, that drop is less can't use water turbine, the utilization ratio of Water Energy is lower, lowered the power of water turbine, simultaneously, in order to obtain certain rated output power, use such water turbine often to need to strengthen drop and water flow, thereby improved cost of investment greatly.
The model utility content
The purpose of this utility model is, at the above-mentioned deficiency of the blade of existing water turbine, provide a kind of simple in structure, improve the waterpower utilization rate of impeller and can increase the turbine impeller of water turbine application area.
For achieving the above object, technological scheme provided by the utility model is:
A kind of turbine impeller, it comprises a turntable body, evenly distributed on this turntable body outer have some bowl-shape blades, is provided with axis hole in this turntable body center.
Be provided with the anchor plate that can increase its intensity in described bowl-shape vacuum side of blade, the back side welding of this anchor plate one side and described bowl-shape blade, another side and the welding of described turntable body outer.
Described anchor plate is provided with a through hole.
The beneficial effects of the utility model are: the utility model is simple in structure, owing to adopt bowl-shape blade, can obviously reduce the adverse current moment of rotation, improve the power of water turbine, make water turbine no longer need bigger water flow and higher water-head, as long as continual current are arranged, and the height of water can be used greater than the height of water turbine water storage box to waste pipe, simultaneously, owing to do not use the blade of former water turbine distortion, blade processing is more prone to, has reduced the price of water turbine; Be provided with axis hole, convenient for assembly; Be provided with anchor plate, strengthened the intensity of bowl-shape blade greatly; Be provided with a through hole in anchor plate, when alleviating its weight, saved raw material, reduce production costs.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Embodiment
Embodiment, referring to Fig. 1, a kind of turbine impeller that present embodiment provides, it comprises a turntable body 1, and evenly distributed on this turntable body 1 outer have ten bowl-shape blades 2, adopts bowl-shape blade 2, obviously reduce the adverse current moment of rotation, improve the power of water turbine, make the water turbine generating no longer need bigger water flow and higher water-head, as long as there are continual current to use; Among other embodiment, the quantity and size of bowl-shape blade 2 can be set by required power actual conditions, provide enough power to guarantee the water wheels function; Be provided with axis hole 3 in this turntable body 1 center, the convenient installation.Be provided with the anchor plate 4 that can increase its intensity in described bowl-shape blade 2 back sides, the back side welding of these anchor plate 4 one sides and described bowl-shape blade 2, weld another side and described turntable body 1 outer, can strengthen the intensity of bowl-shape blade 2 greatly; Described anchor plate 4 is provided with a through hole 4, when alleviating its weight, has saved raw material, reduces production costs.In other embodiments, this anchor plate 4 can adopt nut to make, convenient preparation and saving processing cost.
As described in the utility model the foregoing description, adopt structure same or analogous and the impeller of other structure of obtaining, all in the utility model protection domain with it.
Claims (3)
1. a turbine impeller is characterized in that, it comprises a turntable body, and evenly distributed on this turntable body outer have some bowl-shape blades, is provided with axis hole in this turntable body center.
