Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a solar-powered Internet of Things water meter. Background Art

[0002] Smart water meters, including IC prepaid water meters and NB-IoT IoT water meters, are widely used in households around the world. These meters require a disposable lithium battery installed in the meter terminal to power the meter's electronic module and actuator valves. The production and use of disposable lithium batteries pose significant environmental risks, and the inconsistent charge levels of individual batteries have led to a lack of reliable battery detection methods. This, coupled with the poor operating environments of water meters, leads to frequent battery failures during use. To address this issue, control boxes are often designed with removable batteries. While this allows for on-site battery replacement, it often compromises the waterproofing of the control box, further shortening the battery life. Furthermore, battery replacement in smart water meters is extremely labor-intensive, with high management and labor costs. On-site battery replacement is also impractical, and in practice, the battery is not replaced, with the meter being treated as faulty.

[0003] Water meters installed in indoor and outdoor environments with a sunlight intensity of 400-500 lumens or more can completely replace disposable lithium batteries with polycrystalline low-light solar cell technology. There is no need to replace batteries or consider the poor consistency of disposable lithium batteries, which completely solves the lifelong power consumption problem of smart water meters. However, there has been no particularly good installation location and method for solar panels. Since the cover of existing water meters is opened by flipping up, if installed on the cover, it is easy to forget to close it, resulting in the solar panel not being able to receive light. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the existing technology and provides a solar-powered Internet of Things water meter.

[0005] The utility model is realized through the following technical solution, which provides a solar Internet of Things water meter, including a meter case, a meter cover, a meter cover and a control module. One end of the meter cover is hinged to the meter cover through a vertical hinge shaft, and a vertical through hole is opened at the center of the hinge shaft. A solar panel is fixedly connected to the upper end surface of the meter cover, and the leads of the solar panel are connected to the control module through the through hole.

[0006] The solar panel in this solution is installed on the table cover, and the table cover rotates in a horizontal plane, so the solar panel can always remain facing upward, and the lead wires enter the table cover through the through holes to achieve the connection of the power cord, and the rotation of the table cover does not affect the lead wires.

[0007] As an optimization, the device further comprises a controller housing fixedly connected to one side of the meter cover, wherein the control module is disposed in the controller housing, and a rechargeable battery is also housed in the controller housing. In this solution, the rechargeable battery is charged by the control module to achieve power storage.

[0008] As an optimization, a hollow shaft is fixed to the lower end of the meter cover, and the hollow shaft passes through the meter cover to realize the hinge connection between the meter cover and the meter cover. In this solution, the hinge is realized by the hollow shaft, so that the center hole of the hollow shaft serves as a through hole.

[0009] As an optimization, the upper end of the hollow shaft is threadedly connected to the meter cover. Therefore, the hollow shaft is passed through the meter cover from below and then threadedly connected to the meter cover, thereby achieving a fixed connection between the hollow shaft and the meter cover, which is convenient for installation.

[0010] As an optimization, the lower end of the hollow shaft is provided with an outer convex ring located below the meter cover, thereby preventing the hollow shaft from being pulled out upwards.

[0011] As an optimization, the cover is provided with a mounting hole, and the solar panel is arranged in the mounting hole, so that the upper end surface of the solar panel is flush with or slightly lower than the upper end of the cover, which is convenient for protecting the solar panel.

[0012] The beneficial effects of the utility model are as follows: the utility model is a solar-powered Internet of Things water meter, in which the cover of the Internet of Things water meter is designed to be a flat rotating switch structure, and a solar panel is designed to be installed above the cover. The lead of the solar panel rotates from the hollow shaft of the cover into the Internet of Things control box to charge the rechargeable battery, thereby supplying electricity to the Internet of Things water meter for a long time. The structure is simple, and the solar panel can be kept in a charging state facing upwards at all times, thereby solving the problem of lifelong electricity consumption of the smart water meter throughout its entire life cycle.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0019] like Figures 1-3 As shown, the present invention provides a solar-powered IoT water meter comprising a housing 1, both ends of which are threadedly connected to a water pipe. A cavity is defined within the housing 1, with an opening at the top. The cavity houses, from bottom to top, a metering and counting mechanism 2, a rubber gasket 3, a watch glass 4, a gasket 5, a meter cover 6, and a meter cap 8. The meter cover 6 is tightly threadedly connected to the upper portion of the housing 1.

[0020] The controller housing 7 is fixed to one side of the meter cover 6, and a controller cover 15 is mounted on the controller housing 7. A control module 13 is disposed in the controller housing 7. A rechargeable battery 14 is also mounted in the controller housing 7. The controller housing 7 and the meter cover 6 are connected via a communication hole.

[0021] like Figure 2 As shown, the cover 8 is circular or has a portion removed from the circular shape, and the portion removed from the circular shape is to avoid interference with the controller housing 7.

[0022] A solar panel 9 is affixed to the upper end of the watch cover 8. In this embodiment, the watch cover 8 has a mounting hole, into which the solar panel 9 is mounted. The mounting hole is countersunk and shaped to match the shape of the solar panel 9, ensuring that the upper end of the solar panel is flush with or slightly lower than the upper end of the watch cover, thus facilitating protection of the solar panel. In this embodiment, the area below the solar panel 9 is transparent glass.

[0023] One end of the meter cover 8 is hinged to the meter cover 6 via a vertical hinge shaft. The vertical in this application refers to the direction perpendicular to the upper end surface of the meter cover 6, and a vertical through hole is opened in the center of the hinge shaft. The lead 12 of the solar panel 9 is connected to the control module 13 through the through hole. Figure 3 As shown, the through hole is located below the solar panel 9, so the lead 12 of the solar panel 9 can directly pass through the through hole downward, and then enter the controller housing 7 from the connecting hole between the controller housing 7 and the meter cover 6, thereby connecting with the control module 13, and charging the rechargeable battery through the control module to realize power storage.

[0024] like Figure 3 As shown, a hollow shaft 11 is fixed to the lower end of the meter cover 8 , and the hollow shaft 11 passes through the meter cover 6 to realize the hinged connection between the meter cover 8 and the meter cover 6 .

[0025] Specifically, the lower end of the meter cover 8 is provided with a threaded hole, and the upper end of the hollow shaft 11 is provided with external threads, thereby achieving a threaded connection between the hollow shaft 11 and the meter cover 8. The lower end of the hollow shaft 11 is provided with an external convex ring located below the meter cover 6. During installation, the hollow shaft 11 is passed upward through the meter cover 6 from below and then threaded onto the meter cover 8, thereby achieving a fixed connection between the hollow shaft 11 and the meter cover 8. The hollow shaft 11 then rotates on the meter cover 6, achieving a hinged connection between the meter cover 8 and the meter cover 6.

[0026] The use method of this utility model:

[0027] When the water meter is installed on a pipe using the threaded ends, water flows from left to right. Inside the meter case 1, a movement 2 performs mechanical metering and counting. A rubber gasket 3 seals the movement. A glass 4 facilitates manual observation after opening the meter cover 8. A gasket 5 and a meter cover 6 secure the movement 2.

[0028] On the upper left are the meter cover 8, solar panel 9, and transparent glass 10. These three components are normally closed, positioned directly above the water meter. To view the meter's mechanical reading, simply rotate the meter cover 8. In addition to its normal function as a water meter cover, the meter cover 8 also provides solar power generation. Regardless of position, the solar panel 9 faces upward, facilitating solar light collection and power generation.

[0029] The solar panel 9 is a low-light polycrystalline panel. As long as there is light, it can charge the rechargeable battery 14 through the control module 13. The main functions of the control module 13 are sampling, counting, and communication of the water meter, all of which are powered by the rechargeable battery 14.

[0030] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of the present invention and are not limitations of the present invention.
