[0002] In cold regions such as the north, the water or other liquids in the pipes are prone to freezing and condensing in the low temperatures of winter, causing blockages. Once the pipes are completely blocked, they are difficult to clear again in the low temperatures, and may even have to wait until the temperature rises and the pipes thaw before they can be used again, causing great inconvenience to production and daily life.

[0027] This embodiment provides a pipeline antifreeze device, see reference. Figures 1-7 As shown, the two ends of the pipeline antifreeze device are used to connect to liquid conveying pipelines. The pipeline antifreeze device includes an inner flow pipe 1, with temperature sensors 2 installed at both ends of the inner flow pipe 1. A heating unit 3 is installed on the outer wall of the inner flow pipe 1, which is used to heat the inner flow pipe 1. A retaining ring 11 is sleeved on one end of the inner flow pipe 1, and a control unit 4 is installed on the other end of the inner flow pipe 1. The control unit 4 is ring-shaped and sleeved on the other end of the inner flow pipe 1. The control unit 4 has a built-in controller. The temperature sensors 2 and the heating unit 3 are electrically connected to the controller. Sealing rings 5 ​​are installed at the interfaces at both ends of the inner flow pipe 1, and a sleeve 6 is installed on the outer side of the inner flow pipe 1.

[0028] In the above embodiment, the inner flow pipe 1 is used to connect to a water pipe or a liquid pipe to circulate liquid. Temperature sensors 2 are provided at both ends of the inner flow pipe 1 to measure the temperature of the liquid inside the inner flow pipe 1. A heating unit 3 is provided on the outer wall of the inner flow pipe 1 to heat the frozen liquid inside the inner flow pipe 1 so that it melts and restores its fluidity. A retaining ring 11 is connected to one end of the inner flow pipe 1. The retaining ring 11 is used to prevent slippage, provide a mounting fulcrum, and prevent the accessories outside the inner flow pipe 1 from slipping off one end of the inner flow pipe 1 during assembly, thereby improving the ease of assembly of the antifreeze device. Furthermore, a control unit 4 is provided at the other end of the inner flow pipe 1, and the control unit 4 is ring-shaped and sleeved on the other end of the inner flow pipe 1. The control unit 4 has a built-in controller, such as a microcontroller (MCU) or single-chip microcomputer. The temperature sensor 2 and the heating unit 3 are electrically connected to the controller. When the temperature sensor 2 transmits temperature data to the controller, for example, when the temperature is below the freezing point of water (0°C), the controller controls the heating unit 3 to heat the inner flow pipe 1, so that the ice solid in the inner flow pipe 1 melts. When the temperature sensor 2 detects that the temperature of the inner flow pipe 1 is greater than the freezing point, for example, greater than 10°C, the controller controls the heating unit 3 to stop working to prevent the heating unit from overheating and causing damage to the device components. Furthermore, sealing rings 5 ​​are provided at both ends of the inner flow pipe 1. The sealing rings 5 ​​can be made of rubber or polymer soft material. When the pipes are connected, they are squeezed and deformed to fill the gaps between the connections, thereby improving the sealing performance of the inner flow pipe 1 interface with the water pipe and preventing water leakage at the interface from contacting the antifreeze device components and causing short circuits, freezing and other malfunctions. This is beneficial to improving the stability of the antifreeze device operation. Furthermore, a sleeve 6 is provided on the outside of the inner flow pipe 1. The sleeve 6 serves two purposes: firstly, it protects the antifreeze device components from impact; secondly, a gap exists between the sleeve 6 and the heating element, and the air within this gap is a poor conductor of heat, preventing heat exchange between the sleeve 6 and the outside environment and improving the heating efficiency of the heating unit 3 on the inner flow pipe 1. Additionally, the antifreeze device is connected to the liquid delivery pipeline. By heating the liquid inside the inner flow pipe 1, the heated liquid flows through the frozen pipeline, thawing the condensed sections. Since heat loss occurs during thawing, multiple antifreeze devices need to be installed at intervals along long liquid delivery pipes to prevent freezing and thawing.

[0029] In one embodiment of this application, the internal flow pipe 1 is made of copper pipe.

[0030] In the above embodiments, compared with existing pipes made of iron, stainless steel and aluminum, copper has the highest thermal conductivity and the best heat transfer efficiency, which is beneficial for transferring the heat generated by the heating unit 3 into the inner flow pipe 1 and improving the defrosting efficiency in the inner flow pipe 1.

[0031] In one embodiment of this application, see [reference] Figure 4 As shown, the outer wall of the temperature sensor 2 is provided with a heat insulation layer 21.

[0032] In the above embodiment, the heat insulation layer 21 is used to isolate the heating unit 3 from the temperature sensor 2, prevent the heat generated by the heating unit 3 from damaging the thermal components in the temperature sensor 2, and improve the stability of the temperature sensor 2 during operation.

[0033] In one embodiment of this application, see reference Figure 2 As shown, the heating unit 3 is a heating wire, which is uniformly wound around the outer wall of the inner flow tube 1.

[0034] In the above embodiment, the heating wire is evenly wound around the outer wall of the inner flow tube 1, so that the inner flow tube 1 is heated evenly when heated, and the inner flow tube 1 is prevented from deforming due to uneven heating.

[0035] In one embodiment of this application, see reference Figure 1 As shown, the inner flow pipe 1 is connected to two ends of a connector 12, and the outer ring surface of the connector 12 is provided with a thread.

[0036] In the above embodiments, the outer ring surface of the connector 12 is provided with threads for adapting to the connection and installation of large-diameter pipe openings, or the threads provided on the outer ring surface of the connector 12 can be screwed into the connection port of the liquid conveying pipeline through screwing and engagement with the internal threads at the connection pipe interface. The external threads can be screwed into the connection port of the pipeline, and the threads are radially engaged and fixed with the inner opening of the pipeline. Then, welding, gluing and other leak-proof treatments are performed to improve the compatibility of the antifreeze device installation.

[0037] In one embodiment of this application, see reference Figure 1 As shown, an insulation layer 61 is provided on the outside of the sleeve 6.

[0038] In the above embodiments, the insulation layer 61 is used to keep the temperature when the antifreeze device is not turned on, and the antifreeze device can be started and operated normally at low temperatures. The insulation layer can be made of rock wool.

[0039] In one embodiment of this application, see [reference] Figure 1 As shown, a flow meter 7 is inserted into the internal flow pipe 1.

[0040] In the above embodiment, the flow meter 7 is used to monitor the liquid flow in the inner flow pipe 1. It can directly observe whether there is a blockage in the inner flow pipe 1, or if the liquid flow is not smooth, the pipeline can be cleared and repaired in time.

[0041] This embodiment provides an antifreeze pipeline, including a pipeline antifreeze device and multiple liquid delivery pipelines, and at least one liquid delivery pipeline is connected between two adjacent pipeline antifreeze devices. That is, the antifreeze device installed on the antifreeze pipeline controls and heats the liquid transported in the antifreeze pipeline to achieve the function of preventing freezing or thawing after freezing.

[0042] In actual use, the following configuration is implemented: A control unit 4 is installed at the other end of the internal flow pipe 1, and the control unit 4 is looped around the other end of the internal flow pipe 1. The control unit 4 contains a built-in controller, such as a microcontroller (MCU) or a single-chip microcomputer. Additionally, the control unit 4 also contains a built-in battery power supply for powering the electrical components of the antifreeze device. The temperature sensor 2 and the heating unit 3 are electrically connected to the controller. When the temperature sensor 2 transmits temperature data to the controller, for example, when the temperature is below the freezing point of water (0°C), the freezing point temperature can be adjusted according to the different liquids flowing through the internal flow pipe 1. The controller controls the heating unit... Heating unit 3 heats the inner flow pipe 1 to melt the ice solid inside. When temperature sensor 2 detects that the temperature of the inner flow pipe 1 is greater than the freezing point, for example, greater than 10°C, the controller controls heating unit 3 to stop working to prevent the heating part from being damaged due to excessive temperature. In addition, when the antifreeze device is installed in a long pipeline, the stopping temperature of heating unit 3 can be appropriately increased to increase the temperature of the liquid flowing through the inner flow pipe 1, which facilitates melting and clearing other frozen parts of the long pipeline. To ensure the thawing effect, multiple sets of antifreeze devices are installed at intervals along the long pipeline to prevent the pipeline from freezing.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
