Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meters, and more specifically, to an anti-freezing intelligent water meter. Background Art

[0002] An intelligent water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water consumption and transfer and settle water consumption data. Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, it has made great progress.

[0003] Based on the above, the inventor found that: a protective cover is sleeved outside the existing intelligent water meter, and the protective cover has the function of heat preservation and anti-freezing, avoiding the problem of frost damage of the water meter due to low temperature weather in winter. However, the protective cover mainly prevents cold air from directly contacting the water meter. Once encountering relatively severe low temperature weather, the anti-freezing effect is limited. Therefore, in view of this, the existing structure is studied and improved to provide an anti-freezing intelligent water meter, in order to achieve a more practical purpose.

A group of through grooves 13 are opened inside the adjusting disc 12. In order to filter the inhaled air and prevent dust and impurities from entering the inside of the air duct 6, a filtering mechanism 9 is provided.

[0029] Refer to Figure 1 , water inlet pipes and water outlet pipes are respectively fixedly connected to both ends of the water meter 1, and the water inlet pipes and the water outlet pipes respectively penetrate through both ends of the protective cover 2, and the water meter 1 is installed through the water inlet pipes and the water outlet pipes.

[0030] Refer to Figure 1 , the cover plate 3 is made of a transparent material, one end of the cover plate 3 is movably connected to the protective cover 2, and the other end of the cover plate 3 is snap-connected to the protective cover 2.

[0031] Refer toFigure 2 The air duct 6 is located inside the protective cover 2, and the air duct 6 is arranged in a reciprocating loop shape. Hot air is conveyed through the air duct 6, and at the same time, the moving path of the hot air is extended to heat and prevent freezing of the protective cover 2.

[0032] Refer to Figure 3 The cross-section of the threaded disc 10 is L-shaped, and the threaded disc 10 is threadedly connected to the air inlet 8. Rotating the threaded disc 10 to connect or disconnect it from the air inlet 8 completes the installation or disassembly of the filter assembly.

[0033] Refer to Figure 4 A movable ring is fixedly connected to the center of the inner side of the adjusting disc 12. The movable ring penetrates through the middle of the threaded disc 10, and the movable ring is movably connected to the threaded disc 10 to ensure the rotational stability of the adjusting disc 12 through the movable ring.
