Description

Technical Field

[0001] This application relates to the field of water meter equipment technology, and more particularly to an anti-icing water meter. Background Technology

[0002] A water meter is an instrument used to measure water flow, typically based on the cumulative flow. When using a water meter, it is often affected by external factors such as moisture and low temperatures. For example, in cold weather, the water in the meter may be stagnant or frozen. Under standard atmospheric pressure, 1 kg of water has a volume of 1 cubic decimeter, while 1 kg of ice has a volume of 1.09 cubic decimeters. This means that the water inside the meter will freeze and expand at low temperatures, generating significant expansion pressure.

[0003] However, the core of a traditional water meter is usually filled with purified water. In cold weather, the purified water inside the core will freeze, affecting the normal metering operation of the core mechanism.

[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide an anti-icing water meter, which aims to improve the lubrication of the mechanical parts inside the meter movement and prevent low temperature from causing icing and affecting the normal operation of the meter movement.

[0006] To address the aforementioned technical problems, a first aspect of this application provides an anti-icing water meter, comprising: The water meter body has a receiving groove, and an installation port is provided at one end of the receiving groove. An installation sealing cover is detachably connected to the installation port, and an observation window is provided on the installation sealing cover. And the watch movement device, which is set in a receiving groove. The watch movement device has a sealed cavity, which is filled with antifreeze to purge the air from the sealed cavity.

[0007] In one possible implementation, the watch movement includes: The housing is disposed within the receiving groove; The watch movement mechanism is housed within the watch case. And a protective cover, which is located inside the housing and on the watch movement mechanism; The watch movement mechanism has a dial located near the protective cover, and a first sealing ring is provided between the protective cover and the dial to form a sealed cavity inside the housing.

[0008] In one possible implementation, at least one impeller is movably connected to one end of the housing. The impeller is connected to the watch core mechanism via a rotating shaft. A second sealing ring is provided between the rotating shaft and the housing to form a sealed cavity inside the housing, and the sealed cavity is filled with antifreeze.

[0009] In one possible implementation, a buffer sealing ring is provided between the protective cover and the mounting sealing cover, the buffer sealing ring being used to seal the gap between the protective cover and the receiving groove.

[0010] In one possible implementation, the sealing cover is an annular structure, the protective cover is a disc-shaped protective cover, and the protective cover is a glass protective cover.

[0011] In one possible implementation, a buffer abutment ring is provided on the housing, and a limiting protrusion ring is provided on the inner side wall of the buffer abutment ring. The limiting protrusion ring is arranged around the inner circumference of the buffer abutment ring and protrudes from the upper surface of the buffer abutment ring along the height direction, so that a limiting step is formed between the limiting protrusion ring and the buffer abutment ring. The limiting step is used to accommodate the buffer sealing ring.

[0012] In one possible implementation, the limiting step matches the buffer sealing ring, and at least one buffer notch is provided on the side wall of the limiting protrusion. The diameters of the limiting protrusion and the buffer abutment ring are changed by the contraction or expansion of the buffer notch, which extends to one side of the buffer abutment ring.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0024] This utility model provides, for example Figure 1 and Figure 2 As shown, an anti-icing water meter is used to measure water flow and display the flow rate value on the meter dial 211. The water meter typically measures the cumulative water flow. Its main structure includes a water meter body 1 and a meter core device 2. The water meter body 1 has a receiving groove 11, and one end of the receiving groove 11 has an installation port 12. An installation sealing cover 3 is detachably connected to the installation port 12, and the installation sealing cover 3 has an observation window 31. The water meter body 1 guides the water flow and houses the meter core device 2. When water flows through the water meter body 1, it pushes the impeller 251 on the meter core device 2, which in turn drives the statistical mechanism inside the meter core device 2, thus achieving the effect of measuring water flow. The meter core device 2 is located within the receiving groove 11 and has a sealed cavity containing antifreeze to expel air from the sealed cavity.

[0025] It should be noted that the meter core device 2 in traditional water meters is usually filled with purified water. In cold weather, the purified water in the meter core device 2 will freeze, affecting the normal metering operation of the meter core mechanism 21. This invention fills the sealed cavity with antifreeze, which allows air to be expelled from the sealed cavity. This improves the lubrication of the mechanical parts inside the meter core device 2 and also prevents freezing due to low temperatures from affecting the normal operation of the meter core.

[0026] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the meter core device 2 includes: a housing 25, a meter core mechanism 21, and a protective cover 22. The housing 25 is disposed within the receiving groove 11; the meter core mechanism 21 is disposed within the housing 25; the protective cover 22 is disposed within the housing 25 and is positioned on top of the meter core mechanism 21, corresponding to the observation window 31 on the mounting sealing cover 3. A dial 211 is disposed on the meter core mechanism 21 near the protective cover 22, and a first sealing ring 212 is disposed between the protective cover 22 and the dial 211 to form a sealed cavity within the housing 25. The protective cover 22 can be transparent glass or other non-glass transparent material. During water meter use, the user can directly observe the values ​​on the dial 211 through the observation window 31 and the protective cover 22. The protective cover 22 protects the dial 211 and seals the receiving groove 11, preventing water leakage from the receiving groove 11.

[0027] Furthermore, such as Figure 4 As shown, at least one impeller 251 is movably connected to one end of the housing 25. The impeller 251 is connected to the watch core mechanism 21 through a rotating shaft. A second sealing ring 252 is provided between the rotating shaft and the housing 25 to form a sealed cavity inside the housing 25. The sealed cavity is filled with antifreeze.

[0028] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, a buffer sealing ring 24 is provided between the protective cover 22 and the mounting sealing cover 3. The buffer sealing ring 24 is used to seal the gap between the protective cover 22 and the receiving groove 11. The buffer sealing ring 24 abuts against the step formed at the edge of the observation window 31.

[0029] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the sealing cover 3 is a ring-shaped structure, the protective cover 22 is a disc-shaped protective cover 22, and the protective cover 22 is a glass protective cover 22.

[0030] Furthermore, such as Figure 3 and Figure 4As shown, a buffer abutment ring 23 is provided on the housing 25. A limiting protrusion ring 231 is provided on the inner side wall of the buffer abutment ring 23. The limiting protrusion ring 231 is arranged around the inner circumference of the buffer abutment ring 23. The limiting protrusion ring 231 protrudes along the height direction of the buffer abutment ring 23 and is located on the upper surface of the buffer abutment ring 23, so that a limiting step 232 is formed between the limiting protrusion ring 231 and the buffer abutment ring 23. The limiting step 232 is used to accommodate the buffer sealing ring 24.

[0031] Traditional water meters typically have their glass cover fixed directly above the base meter. This results in insufficient buffer space between the glass cover and the base meter, meaning the pressure from the expansion of frozen water inside the meter acts directly on the glass cover, causing it to bulge, deform, or shatter. This significantly impacts the lifespan of the water meter.

[0032] This invention utilizes the elastic deformation properties of the buffer abutment ring 23 and buffer sealing ring 24 located above the glass of the dial 211. When the water meter's interior freezes and expands due to low temperatures, the glass of the dial 211 (protective cover 22) and the watch movement 2 are pushed outward by the internal expansion pressure. This effectively buffers the displacement of the glass of the dial 211 caused by the expansion of ice inside the water meter, preventing the pressure generated by the expansion from directly acting on the glass and causing it to bulge, deform, or crack.

[0033] In addition, when assembling and manufacturing water meters, the limiting step 232 makes it easier to assemble the buffer sealing ring 24. This prevents the buffer sealing ring 24 from deforming due to extrusion pressure during the assembly and installation of the sealing cover 3, thus avoiding the deformed part of the buffer sealing ring 24 from falling out of the installation position and affecting the sealing effect.

[0034] Furthermore, the limiting step 232 matches the buffer sealing ring 24, and at least one buffer notch 2311 is provided on the side wall of the limiting protrusion ring 231. The diameters of the limiting protrusion ring 231 and the buffer abutment ring 23 are changed by the contraction or expansion of the buffer notch 2311, which extends to one side of the buffer abutment ring 23.

[0035] It should be noted that in low-temperature environments, the pressure generated by the expansion of water freezing inside the water meter will directly act on the protective cover 22 (glass cover), and the protective cover 22 will slightly shift upwards. At this time, the compressive force on the upper and lower ends of the buffer sealing ring 24 will increase, causing deformation. The buffer abutment ring 23 and the limiting protrusion ring 231, which serve as the carriers of the buffer sealing ring 24, will also deform under high pressure. Therefore, in this embodiment, at least one buffer notch 2311 is provided on the side wall of the limiting protrusion ring 231. The deformation stress of the buffer abutment ring 23 and the limiting protrusion ring 231 can be released through the buffer notch 2311. It also provides a buffer zone during the deformation of the buffer sealing ring 24. This improves the sealing effect of the buffer sealing ring 24 and the overall buffering effect of the sealing structure.

[0036] Furthermore, the buffer abutment ring 23 and the limiting protrusion ring 231 are integrally formed. This increases the overall structural strength of the entire buffer sealing ring 24 carrier (buffer abutment ring 23, limiting connector, and limiting protrusion ring 231), as well as the sealing performance between structural components. It prevents water leakage through the gaps between structural components.

[0037] Furthermore, such as Figure 1 , Figure 2 As shown, the water meter body 1 is also provided with an inlet port 13 and an outlet port 14, both of which are connected to the receiving groove 11.

[0038] Furthermore, such as Figure 2 As shown, the mounting sealing cover 3 has a mounting thread 33 on its side wall. The mounting thread 33 is arranged around the circumference of the mounting sealing cover 3, and the mounting sealing cover 3 is screwed onto the mounting port 12 through the mounting thread 33.

[0039] In summary, this application provides an anti-icing water meter. The present invention fills the sealed cavity with antifreeze, which allows air to be expelled from the sealed cavity. This improves the lubrication of the mechanical components within the meter movement 2 and prevents icing caused by low temperatures from affecting the normal operation of the meter movement.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
