Description
Technical Field
[0001] This utility model relates to the field of water meter technology, specifically to an anti-clogging rotary vane water meter. Background Technology
[0002] Rotary vane water meters are a type of flow meter. They are suitable for measuring the total unidirectional water flow in small-diameter pipes, such as household water consumption using pipes with diameters of 15mm or 20mm. These water meters mainly consist of a casing, an impeller measuring mechanism, a reduction mechanism, and an indicator, and are characterized by their simple structure.
[0003] A search revealed a rotary vane water meter (publication number: CN218297272U) in the prior art. The paper describes that "a counting component is installed on the upper part of the water meter body; a movable cover is hinged to the rear side of the upper part of the counting component; a protective cover is movably secured to the upper side of the counting component; the upper edge of the counting component is recessed inward to form multiple equally spaced slots, each slot including vertical and horizontal slots; the lower end of the vertical slot communicates with the right end of the horizontal slot; an instrument panel is provided on the upper part of the counting component; multiple locking blocks are provided on the lower side of the inner wall of the protective cover; a sponge sheet is movably secured to the upper side of the inner side of the protective cover through multiple locking blocks; and a lighting element is threadedly connected to the upper part of the protective cover." This water meter, through the sponge sheet, facilitates user viewing of the instrument panel; if the instrument panel is unclear, it can be easily illuminated. The meter can be wiped with a sponge, eliminating the need for additional cleaning. The lighting design, which is independent of the counting components and the main body of the meter, provides illumination when the meter is in a dark environment, allowing users to clearly observe the dashboard and facilitating future maintenance. It does not increase the manufacturing difficulty of the meter body or counting components. However, the meter lacks a corresponding anti-clogging structure, allowing impurities in the water to easily enter the counting components, affecting measurement accuracy and making readings difficult. More seriously, when water supply is restored after maintenance, the sudden surge of water can easily flush dirt deposited at the bottom of the meter casing and in the pipes into the counting components, contaminating the inside, making the indicator panel invisible, and causing blockages within the meter.

[0018] Reference Figures 1 to 4 As shown, this utility model provides an anti-clogging rotary vane water meter, including: an anti-clogging component 3, which is fixedly connected to the end face of the water inlet pipe 2 of the water meter body 1 by a fastener. The anti-clogging component 3 consists of a shell 13, a main mounting frame 12, and a secondary mounting frame 14. The upper end of the outer side of the shell 13 is symmetrically connected to a storage plate 8. A movable plate 9 is slidably connected to the inside of the storage plate 8 by a fastening bolt 18. A fastening block 10 is fixedly connected to the upper end of the movable plate 9. A cover plate 17 is fixedly connected to the upper surface of the shell 13 by the fastening block 10. A positioning plate 7 is symmetrically connected to the inner cavity of the shell 13. Positioning grooves are opened on the outer sides of the main mounting frame 12 and the secondary mounting frame 14 relative to the positions of the positioning plates 7. At the same time, a horizontal bar 11 and a vertical bar 4 are fixedly connected to the inner cavity of the main mounting frame 12, and a coarse filter screen 6 is fixedly connected to the end of the inner cavity of the main mounting frame 12 away from the horizontal bar 11. A support component 15 is fixedly connected inside the secondary mounting frame 14, and a fine filter screen 16 is fixedly connected to the surface of the support component 15.
[0019] In this embodiment, when the fluid in the pipe flows through the main body 1 of the rotary vane water meter, it first passes through the anti-clogging component 3 installed at the inlet pipe 2 of the main body 1. After flowing into the housing 13, the fluid sequentially passes through the horizontal bar 11, the vertical bar 4, the coarse filter screen 6, and the fine filter screen 16. The horizontal bar 11 and the vertical bar 4 are designed to intercept larger debris in the fluid and effectively reduce the probability of debris completely adhering to the surface of the coarse filter screen 6, leaving sufficient gaps between the intercepted debris, thereby enabling... The coarse filter 6 is reduced, while the fine filter 16 can perform secondary filtration of the fluid flowing through the housing 13. The support component 15 in the sub-mounting frame 14 can effectively increase the filtration area of the fine filter 16, thereby helping to reduce the chance of the fine filter 16 being blocked. Furthermore, the multiple filtration and anti-blocking structure in the anti-blocking component 3 can effectively reduce the chance of impurities in the fluid interfering with the internal structure of the rotor water meter body 1, and reduce the chance of the rotor water meter being blocked.
[0020] In a preferred embodiment, the cross-section of the housing 13 is U-shaped, and the four sets of positioning plates 7 fixedly connected to the inner cavity of the housing 13 are all elongated.

Meanwhile, a sealing layer is fixedly connected to the upper surface of the housing 13, and a sealing strip is provided on the lower surface of the cover plate 17 relative to the position of the sealing layer. The sealing strip is U-shaped.
[0021] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The sealing layer and sealing strip help to enhance the sealing performance at the connection between the housing 13 and the cover plate 17, improve the overall sealing effect of the anti-clogging component 3, and reduce the chance of leakage.

All sets of horizontal bars 11 are cylindrical in shape. In addition, multiple sets of vertical bars 4 are fixedly connected in parallel and at equal intervals along the horizontal direction inside the main mounting frame 12. All sets of vertical bars 4 are elongated in shape and have a square cross-section. The vertical bars 4 and the horizontal bars 11 are combined to form a grid-like structure.
[0025] In this embodiment, as Figure 2 and Figure 3 The structure of the horizontal bar 11 and the vertical bar 4 allows the main mounting frame 12 to be axially misaligned to intercept larger impurities in the fluid, thereby reducing the probability of impurities piling up and completely clogging the coarse filter screen 6.
[0026] In a preferred embodiment, multiple sets of misaligned plates 5 are fixedly connected parallel to each other at equal intervals along the length direction on the surface of the vertical rod 4.
