Description

Technical Field

[0001] The utility model relates to the technical field of metering water meters, in particular to a stable impeller mechanism used in an intelligent water meter. Background Art

[0002] The water meter impeller is a major component of the rotary vane water meter. Water flows into the water pipe and passes through the inner cavity of the water meter case. The water flows into the impeller blades to drive the impeller to rotate, and the pointer of the counting mechanism of the water meter rotates through the gear transmission, so that the meter needle and the character wheel display the water consumption.

[0003] The existing impeller mechanism is usually equipped with multiple blades, but most of the blades adopt a linear structure. Due to the large resistance of water flow, a large pressure loss is generated during the water flow metering process, which also affects its flow metering performance. As a result, arc blades, that is, curved blades, appear. Although the shape has changed, after a long period of water flow impact, impact pressure is still generated on the blades, and the structure is unstable. In view of the above problems, it is more important to design a stable impeller mechanism for smart water meters. Utility Model Content

[0004] The purpose of the utility model is to provide a stable impeller mechanism used in a smart water meter to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stable impeller mechanism used in a smart water meter, comprising a wheel axle, a pin shaft, an upper bracket, a lower bracket and blades, the upper bracket and the lower bracket are fixedly arranged on the surface of the wheel axle, blades are fixedly arranged between the upper bracket and the lower bracket, and the blades are tightly connected to the wheel axle.

[0006] Preferably, pins are fixedly provided at the upper and lower ends of the wheel axle, and a pin hole is provided on the pin.

[0007] Preferably, the upper bracket, the lower bracket and the blades constitute a set of impeller mechanisms, and 3 to 7 impeller mechanisms are arranged in a circular array on the wheel shaft.

[0008] The beneficial effects of the utility model are as follows: the stable impeller mechanism used in the smart water meter is provided with an upper bracket, a lower bracket and blades, and both ends of the blades are fixedly installed between the upper bracket and the lower bracket. At the same time, the mechanism is fixedly installed on the wheel axle. When the water flows through the blades, the pressure brought about by the pressure will form an effective support through the upper bracket and the lower bracket, so that the blades can be used stably, avoiding the instability caused by the operation of traditional blades and improving the use requirements.
