[0021] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] Combined with appendix Figure 1 A graphene-based antifreeze water meter includes a water meter 1 and a heating pipe 2. The heating pipe 2 is installed in the middle section of a liquid flow pipe 3. After the heating pipe 2 is installed inside the liquid flow pipe 3, the liquid medium in the liquid flow pipe 3 directly enters the heating pipe 2. The medium in the liquid flow pipe on one side of the heating pipe 2 flows through the heating pipe 2 to the liquid flow pipe 3 on the other side. The water meter 1 is also installed on the liquid flow pipe 3, and the water meter 1 and the heating pipe 2 are close to each other to facilitate wiring between the heating pipe 2 and the water meter 1. This allows the water meter 1 to control the opening of the heating pipe 2 and display the temperature of the liquid medium flowing in the heating pipe 2.

[0024] The heating pipe 2 includes a graphene heating element, a temperature sensor 5, a power supply module, and a control module. The graphene heating element and temperature sensor 5 are installed inside the heating pipe 2, with only a few ports reserved on the surface of the heating pipe 2 for wiring. The power supply module and control module can be fixedly mounted on the heating pipe 2 or integrated into the water meter 1. The control module is electrically connected to the graphene heating element, temperature sensor 5, and power supply module via wiring. The power supply module provides power to the graphene heating element and temperature sensor 5. The control module collects the temperature detected by the temperature sensor 5 to determine whether the graphene heating element needs to be turned on to heat the liquid medium inside the heating pipe 2.

[0025] Graphene's high electrical and thermal conductivity allow it to be integrated as a heating element in smart water meter 1. The electrothermal effect of graphene provides freeze protection for water meter 1.

[0026] The interior of heating pipe 2 is a hollow pipe for supplying liquid medium flow. Graphene heating elements are inserted into heating pipe 2. One end of the graphene heating element has an integrated port. Several graphene heating plates are fixed to the graphene port 4. Graphene port 4 not only facilitates the installation of graphene heating plates, but also allows wiring to be routed through graphene port 4 to supply power to multiple graphene heating plates.

[0027] The graphene heating element is inserted into the heating pipe 2 through the graphene port 4. The multiple graphene heating elements include arc-shaped heating elements on both sides and grid heating elements between the arc-shaped heating elements on both sides. The arc-shaped heating elements are attached to the sides of the heating pipe 2, and the grid heating elements are set inside the heating pipe 2. The liquid medium in the heating pipe 2 can flow directly through the grid heating elements. Therefore, the grid heating elements can fully contact the liquid medium in the heating pipe 2, thereby uniformly heating the liquid medium.

[0028] In other embodiments, the grid heating element can be replaced with intermittently arranged strip heating elements, and the liquid medium in the heating pipe 2 can also pass through the intermittently arranged strip heating elements.

[0029] A temperature sensor 5 is also fixedly installed inside the heating pipe 2. The temperature sensor 5 is fixedly installed behind the graphene heating element in the direction of medium flow inside the heating pipe 2, so that when the temperature sensor 5 detects the temperature, it can detect the liquid medium heated by the graphene heating element.

[0030] One end of the temperature sensor 5 extends out of the heating pipe 2, which facilitates connection to the power module and the control module.

[0031] Work process

[0032] Temperature monitoring: Temperature sensor 5 monitors the temperature of the liquid medium inside heating pipe 2 in real time.

[0033] Temperature judgment: The control module receives temperature data and determines whether it is lower than the pre-approved temperature value.

[0034] Heating start: If the temperature is lower than the set value, the control module will activate the graphene heating element to heat the liquid medium.

[0035] Heating process: The graphene heating element generates heat to prevent water meter 1 from freezing.

[0036] Temperature recovery: After the temperature recovers, the control module stops the heating element from working.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
