Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a smart water meter. Background Technology

[0002] In the field of smart water meters, non-magnetic sampling and Hall effect sampling technologies have become the mainstream choice in the domestic market due to their significant advantages, such as electromechanical separation, ease of maintenance, and precise metering capabilities. As domestic water meter products gradually expand into the international market, meeting the technical standards of different countries and regions has become a key challenge. Standards vary significantly across regions. For example, the South African market mandates SABS certification for water meters, based on the extremely stringent SANS-1529-1-2019 (Ed.-2.04) standard, which places extremely stringent requirements on water meter performance, especially static pressure testing. In contrast, the corresponding domestic standard, GB / T778.1-2018 "Drinking Cold Water Meters and Hot Water Meters Part 1: Metering Requirements and Technical Requirements," has relatively lenient static pressure requirements. Taking small-diameter water meters (DN15~DN25) as an example, the South African standard requires a static pressure test of 4.8 MPa for 15 minutes, while the domestic standard only requires a maximum of 2 MPa for 1 minute. This demonstrates that South Africa's static pressure testing standards are far higher than those in China.

[0003] Currently, the water meters that meet the stringent static pressure requirements of South African SABS certification are mainly ultrasonic water meters. However, ultrasonic water meters are significantly more expensive than non-magnetic or Hall effect water meters, which limits their competitiveness in price-sensitive markets to some extent. Furthermore, ultrasonic water meters are often difficult to design with electromechanical separation, leading to inconvenience in later maintenance and repair.

[0004] The non-magnetic or Hall effect sampling water meters commonly used in China are designed primarily according to domestic standards (a maximum static pressure requirement of 2 MPa for 1 minute). Within this design framework, considering the accuracy requirements of the sensing distance for non-magnetic sampling technology and the characteristics of flow measurement (the sensing element cannot be too close to the meter cover glass), current market products generally use 6mm thick tempered glass as a safety shield. However, the pressure resistance limit of such tempered glass is typically 3-4 MPa. When the static pressure exceeds 3 MPa, the glass faces an extremely high risk of breakage. If the tempered glass is replaced with a polymer material of the same specifications (such as resin or polycarbonate PC), although its compressive strength may reach approximately 4 MPa, the material will undergo significant deformation under high pressure. This deformation will push open the upper electronic sampling chamber, causing the sampling element to fail and malfunction. Utility Model Content

[0005] This utility model provides a smart water meter to solve the defect of existing smart water meters that cannot meet higher static pressure requirements.

[0006] This utility model provides a smart water meter, including: a base meter unit and an electronic module unit, wherein the base meter unit and the electronic module unit are detachably connected to achieve electromechanical separation; the base meter unit includes pressure-bearing glass, wherein the surface of the pressure-bearing glass facing the user is an arc-shaped surface, and the pressure-bearing glass is plastic glass.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0029] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] The following is combined with Figures 1-7 This invention describes the smart water meter.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of this utility model, the smart water meter includes a base meter unit 10 and an electronic module unit 20. The base meter unit 10 and the electronic module unit 20 are detachably connected. The base meter unit 10 includes a pressure-bearing glass 16, the surface of which faces the user is an arc-shaped surface, and the pressure-bearing glass 16 is made of plastic glass.

[0033] Specifically, in this embodiment, the smart water meter uses plastic glass, which has extremely high impact resistance and toughness, making it difficult to break. Even under strong impact, it will typically only deform or crack, rather than shatter into fragments like tempered glass. Designing the user-facing surface of the plastic glass as a rounded surface increases the local thickness of the pressure-bearing glass 16, transferring and reducing the deformation caused by stress to resist glass deformation under high pressure. This also enhances the pressure resistance of the base meter unit 10, enabling the smart water meter to withstand high pressure.

[0034] The smart water meter provided in this embodiment of the utility model increases the local thickness of the pressure-bearing glass by designing the glass in a conventional smart water meter as plastic glass and designing the surface of the plastic glass facing the user as an arc-shaped surface. This increases the deformation caused by stress and reduces it, thereby resisting glass deformation under high pressure and enabling the pressure-bearing glass to withstand higher pressure, thus meeting the certification requirements of South Africa.

[0035] like Figure 3 As shown, in an embodiment of this utility model, the pressure-bearing glass 16 includes: a first glass body 161 and a second glass body 162. The first glass body 161 is a circular sheet of glass, and the second glass body 162 is stacked on top of the first glass body 161. The side surface of the second glass body 162 facing away from the first glass body 161 is an arc-shaped surface.

[0036] Specifically, in this embodiment, by setting the pressure-bearing glass 16 as two layers of glass and setting the outer glass as an arc-shaped surface, the local thickness of the pressure-bearing glass 16 can be increased, the pressure resistance of the glass can be improved, and the deformation of the pressure-bearing glass 16 under high pressure can be avoided. The arc-shaped setting can also reduce the shrinkage problem during the injection molding process and prevent the meter reading from being affected by shrinkage.

[0037] Furthermore, in an embodiment of this utility model, the thickness of the first glass body 161 can be the same as the thickness of the glass in a conventional smart water meter.

[0038] like Figure 1 As shown, in an embodiment of this utility model, the base watch unit 10 further includes a first housing 11 and a movement 12. The first housing 11 is detachably connected to the electronic module unit 20 to achieve electromechanical separation. The movement 12 is disposed within the first housing 11 and has an indicating component 13. A first glass body 161 is connected to the first housing 11 to encapsulate the movement 12 within the first housing 11. A second glass body 162 has a notch 1621, which is opposite to the indicating component 13.

[0039] Specifically, in this embodiment, the indicating component 13 can be a non-magnetic induction wheel or a Hall effect magnetic needle; that is, the smart water meter provided in this embodiment can be a non-magnetic water meter or a Hall effect water meter. Figure 5 As shown, the notch 1621 on the second glass body 162 is used to accommodate the module compartment 19, which is used to install a non-magnetic module or a Hall module so that the indicating component 13 can work. In this embodiment, the thickness of the first glass body 161 is equal to the thickness of the glass in a conventional smart water meter. By setting the notch 1621 on the second glass body 162, the module compartment 19 is set within the notch 1621, so that the measurement distance remains unchanged. However, if the second glass body 162 is also set as a circular sheet glass body, since the thickness of the pressure-bearing glass 16 is increased, its ability to resist high-pressure deformation will naturally be improved. However, setting the module compartment 19 outside the second glass body 162 will increase the sampling distance, making it impossible for existing non-magnetic technology to measure. Furthermore, the notch 1621 can protect the lower part of the module compartment 19, preventing the insertion of metal sheets, thereby ensuring that the measurement is not affected.

[0040] It is understood that when the pressure-bearing glass 16 in this embodiment is replaced with ordinary glass, the smart water meter provided by this embodiment can meet domestic certification requirements. The smart water meter provided by this embodiment can meet different usage environments and certification standards simply by replacing the glass, improving the applicability of the smart water meter and making it more competitive in the market. At the same time, the installation process is simple, reducing the overall cost of the meter.

[0041] like Figure 4 As shown, in an embodiment of this utility model, the surface of the first glass body 161 facing away from the second glass body 162 is provided with an annular positioning rib 1611, and the annular positioning rib 1611 is engaged with the mechanism 12.

[0042] Specifically, to prevent the position of the module compartment 19 from changing during installation and affecting the accuracy of measurement, an annular positioning rib 1611 is provided on one side of the first glass body 161. When the first glass body 161 is connected to the first housing 11, the annular positioning rib 1611 engages with the mechanism 12, thereby preventing the first glass body 161 from rotating and ensuring that the position of the module compartment 19 is exactly opposite to the indicating component 13.

[0043] like Figure 1 As shown, in an embodiment of this utility model, the base watch unit 10 further includes a sealing ring 14 and a height limiting ring 15. The sealing ring 14 and the height limiting ring 15 are sequentially disposed inside the first housing 11, and the pressure-bearing glass 16 is located on one side of the height limiting ring 15, so as to encapsulate the movement 12 inside the first housing 11.

[0044] Furthermore, such as Figure 1 As shown, the base unit 10 also includes a washer 17 and a cover 18. The washer 17 is disposed on one side of the second glass body 162, and the cover 18 is detachably connected to the first housing 11 and abuts against the washer 17. Optionally, in this embodiment, the cover 18 can be threadedly connected to the first housing 11. When the cover 18 is screwed on, the annular positioning rib 1611 on the first glass body 161 engages with the movement 12, thereby preventing the pressure-bearing glass 16 from rotating and ensuring that the position of the module compartment 19 remains unchanged, always opposite to the indicating component 13, thus ensuring reliable installation and detection accuracy of the smart water meter.

[0045] In an embodiment of this utility model, the electronic module unit 20 includes: a base and an electronic module, the electronic module being disposed within the base. For example... Figure 2 As shown, the base has a through hole 201. After the base meter unit 10 is installed, the base meter unit 10 is inserted into the through hole 201, and then the base meter unit 10 is detachably connected to the base through the base meter valve stem 31 and the bolt 32.

[0046] like Figure 1 As shown, in an embodiment of this utility model, the base includes a second housing 21 and a cover 22. The second housing 21 is detachably connected to the base unit 10, one end of the cover 22 is hinged to the second housing 21, and the other end of the cover 22 is snapped into the second housing 21.

[0047] Specifically, in this embodiment, the cover 22 can be closed or opened with the second housing 21. When it is necessary to check the water meter, the cover 22 can be opened; when it is not necessary to check the water meter, the cover 22 can be engaged with the second housing 21.

[0048] Specifically, such as Figure 6 and Figure 7 As shown, the end of the cover 22 that is engaged with the second housing 21 is provided with a buckle 221, and the surface of the second housing 21 facing the cover 22 is provided with a slot. When the buckle 221 is inserted into the slot, the cover 22 and the second housing 21 can be engaged to protect the display and dial of the base unit 10 and prevent dust from covering and affecting the reading.

[0049] like Figure 5 As shown, in an embodiment of this utility model, the electronic module unit 20 further includes an antenna 23, which is disposed on the outer surface of the base and electrically connected to the electronic module. The antenna 23 has a shark spine shape.

[0050] Specifically, the smart water meter provided in this embodiment of the present invention is compatible with LoRa communication. Since LoRa communication has high requirements for the antenna 23, the smart water meter adopts an extended antenna to improve the communication rate of the antenna 23. Optionally, in this embodiment, the antenna 23 adopts a shark spine shape.

[0051] The smart water meter provided in this embodiment of the utility model is compatible with the requirements of high pressure resistance meters and domestic standard static pressure requirements. The smart water meter can realize electromechanical separation, non-magnetic Hall effect replacement, and is compatible with multiple communication methods such as NB or LoRa. At the same time, it can realize multiple functions such as flip cover locking to prevent metal sheet insertion, thus ensuring metering accuracy.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
