Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] The orientations mentioned in this specification are based on the orientation of the IoT valve-controlled water meter of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0030] like Figure 1-7 As shown, an IoT valve-controlled water meter includes a water pipe section 1, with one end of the water pipe section 1 being a water inlet and the other end being a water outlet. A lower water meter housing 2 is fixedly mounted on the top of the water pipe section 1. Two sensor holes 11 and one valve hole 12 are provided at the connection between the water pipe section 1 and the lower water meter housing 2. A higher water meter housing 3 is detachably connected to the top of the lower water meter housing 2. The upper water meter housing 3 contains a main control board 31, a communication board 32, and a display screen 33. The main control board 31 contains a main control module and a self-maintenance module. The lower water meter housing contains a sensor module, a power module, and a valve actuator 6. The sensor module, the valve actuator 6, and the communication board 32 are all electrically connected to the main control board 31, and the communication board 32, the main control board 31, and the valve actuator 6 are all electrically connected to the power module.

[0031] The valve actuator 6 includes an electric actuator 61, a valve stem 62, and a valve body 63. The electric actuator 61 is fixedly installed inside the lower housing 2 of the water meter. Specifically, the electric actuator 61 is a motor actuator. The output end of the electric actuator 61 is fixedly connected to one end of the valve stem 62. The other end of the valve stem 62 extends out of the lower housing 2 of the water meter and enters the water pipe section 1 through the valve hole 12. The end of the valve stem 62 away from the electric actuator 61 is connected to the valve body 63. The valve body 63 is rotatably installed inside the water pipe section 1. Specifically, the valve body 63 is a zirconia ceramic valve body. The zirconia ceramic valve body has a smooth surface and high hardness, resists scale deposition, reduces frictional resistance during rotation, and thus prevents valve body jamming.

[0032] The main control module controls the start and stop of the electric actuator 61, thereby controlling the valve body 63 to rotate, thus opening and closing the valve body 63. The self-maintenance module also controls the start and stop of the electric actuator 61, thereby controlling the valve body 63 to rotate slightly, preventing the valve body 63 from being covered by scale or impurities due to long-term stagnation, and avoiding the interruption of water supply to users caused by full opening or closing.

[0033] The bottom of the water meter upper shell 3 is provided with a main control board base 5. The top surface of the main control board base 5 and the water meter upper shell 3 form a sealed space. The main control board 31, communication board 32 and display screen 33 are all located in the sealed space, which further seals the main control board 31, communication board 32 and display screen 33 located in the sealed space, avoiding the problem of the main control board, communication board or display screen getting wet due to accidental water leakage.

[0034] The power module includes a main battery 7 and a supercapacitor 8, which ensures that the valve body 63 can be shut off in an emergency before the main battery 7 is depleted. The combination of the main battery 7 and the supercapacitor 8 ensures that a large current can be instantly started to supply power when the valve body 63 is activated.

[0035] The lower casing 2 of the water meter has a main battery slot 21 and a capacitor slot 22. The main battery 7 is snapped into the main battery slot 21, and the supercapacitor 8 is fixedly installed in the capacitor slot 22. The main battery 7 can be replaced simply by disassembling the upper casing 3 and the lower casing 2 of the water meter, which facilitates the maintenance of the IoT valve-controlled water meter by the staff.

[0036] A water meter cover plate 4 is hinged to one end of the top surface of the water meter upper shell 3 near the display screen 33. The water meter cover plate 4 has two mounting slots 41, and a sliding cover 42 is slidably installed in each of the two mounting slots 41. Both sliding covers 42 are semi-circular. When the user or staff only needs to see the data on the display screen 33, they can rotate one of the sliding covers 42 to make it overlap with the other sliding cover 42. As a result, the display screen 33 is gradually revealed without having to open the water meter cover plate 4. This avoids damage to the hinge joint between the water meter cover plate 4 and the water meter upper shell 3 caused by opening and closing the water meter cover plate 4. At the same time, the water meter cover plate 4 can be opened so that it can be fully opened for subsequent troubleshooting by staff.

[0037] The sensor module includes two sensors 9 fixed to the bottom of the lower housing of the water meter. The probes of the two sensors 9 extend into the water pipe section 1 through two sensor holes 11 to detect the water flow rate in the water pipe section 1.

[0038] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
