Self-powered water meter and power generation module thereof

Abstract

A self-powered water meter and a power generation module (3) thereof. The self-powered water meter includes a housing (1), an intelligent water meter module (2), and a power generating module (3). The housing (1) has a first cavity (11) and a second cavity (12), and the second cavity (12) communicates with the first cavity (11). The intelligent water meter module (2) is mounted in the first cavity (11). The power generating module (3) is mounted in the second cavity (12). The power generating module (3) includes a generator (31), a first flow guide structure (32), and a power generating impeller (33). The first flow guide structure (32) includes a set of first guide vanes (321). The number of the first guide vanes (321) is 10-60. Each of the first guide vanes (321) has a first blade bending angle, and the first blade bending angle is 50-75 degrees. The first flow guide structure (32) guides a water flow to the power generating impeller (33), and the power generating impeller (33) rotates such that the generator (31) generates power.
