Abstract

The utility model discloses a curved surface impeller blade structure, including the impeller, around installing a plurality of blades on the impeller, one of them terminal surface of blade is linear structure, and the blade is the curved surface with the corresponding another side of linear structure terminal surface. The utility model discloses owing to adopted this kind of structure, can make the impeller can both obtain great kinetic energy all the time, its water gauge is at the accuracy that just can be more when little flow measurement finally.

Description

Curved surface impeller blade structure

Technical Field

The utility model relates to a water gauge impeller blade structure, in particular to curved surface impeller blade structure.

Background

In the existing water meter, the impeller blades of the water meter with the rotor wing type structure are all in a non-curved surface structure, as shown in the following fig. 2;

the non-curved surface blade has the advantages of simple structure and easy measurement. The main disadvantage is that when the water flow impacts the blades to rotate, the direction of the water flow is not always perpendicular to the blades so as to obtain the maximum kinetic energy, and finally, when the flow of the water flow is small, the blades cannot obtain enough kinetic energy so as to cause a large metering error.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide curved surface impeller blade structure, the utility model discloses owing to adopted this kind of structure, can make the impeller can both obtain great kinetic energy all the time, final its water gauge just can be more accurate when little flow measurement.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a curved surface impeller blade structure, including the impeller, around installing a plurality of blades on the impeller, one of them terminal surface of blade is linear structure, the blade is the curved surface with the corresponding another side of linear structure terminal surface.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses owing to adopted this kind of structure, can make the impeller can both obtain great kinetic energy all the time, its water gauge is at the accuracy that just can be more when little flow measurement finally.

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

FIG. 1 is an overall structure of the present invention;

FIG. 2 is a vane structure view of a prior art water meter impeller;

fig. 3 is a schematic view of an embodiment of the present invention;

in the figure: 1. an impeller; 2. a blade; 3. a curved surface.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention. Wherein like reference numerals refer to like parts throughout.

In addition, if a detailed description of the known art is not necessary to show the features of the present invention, it is omitted. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1

As fig. 1, the utility model provides a curved surface impeller blade structure, including impeller 1, around installing a plurality of blades 2 on the impeller 1, one of them terminal surface of blade 2 is linear structure, and blade 2 is curved surface 3 with the corresponding another side of linear structure terminal surface.

Specifically, the structural principle is that when water flow in the water meter impacts the blades 2 of the impeller 1 to rotate counterclockwise, the design of the curved surface of the blade can enable the impact force F of the water flow on the blades 2 to be always on the normal of the curved surface of the blades 2 in the rotation process of the impeller 1, as shown in fig. 3.

The utility model discloses owing to adopted this kind of structure, can make impeller 1 can both obtain great kinetic energy all the time, final its water gauge just can be more accurate when little flow measurement.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
