Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: an electric heating tape for pipeline antifreeze, comprising: a pipeline 1, an insulation sleeve 3 on the surface of the pipeline 1, and a heating tape body 4 on the inner side of the insulation sleeve 3; a plurality of connecting parts 2 on the surface of the insulation sleeve 3, each connecting part 2 including a fixing ring 17; the fixing ring 17 having a semi-arc structure and forming a circular fixing structure between two sets of fixing rings 17; connecting blocks 6 on both sides of the fixing ring 17, and fixing bolts 7 inside the connecting blocks 6; a plurality of connecting posts 9 inside the fixing ring 17, with the connecting posts 9 threadedly connected to the fixing ring 17; the connecting posts 9 are rotated to make them contact the surface of the pipeline 1; the heating tape body 4 is wound around the surface of the connecting posts 9 and distributed in a U-shaped serpentine pattern on the surface of the pipeline 1. The surface of the pipe is provided with an insulation sleeve 3, and the inner side of the insulation sleeve 3 is provided with a heating cable body 4. Several sets of connectors 2 are provided on the surface of the insulation sleeve 3, and the connectors 2 include fixing rings 17. The fixing rings 17 are arranged in a semi-arc structure, and a circular fixing structure is formed between two sets of fixing rings 17. Connecting blocks 6 are provided on both sides of the fixing rings 17, and fixing bolts 7 are provided inside the connecting blocks 6. Several sets of connecting posts 9 are provided inside the fixing rings 17, and the connecting posts 9 are threadedly connected to the fixing rings 17. By rotating the connecting posts 9, they are brought into contact with the surface of the pipe 1. The heating cable body 4 is wrapped around the surface of the connecting posts 9, so that it is distributed in a U-shaped serpentine pattern on the surface of the pipe 1. This distribution method increases the connection area with the pipe 1 and improves the heating efficiency. At the same time, the insulation sleeve 3 can reduce the heat loss of the heating cable body 4.
[0020] Further improvements, such as Figure 3 As shown: The surface of the connecting column 9 is provided with a fixed connection knob 8, and the knob 8 is hexagonal in shape. The hexagonal knob 8 is easy to rotate with tools, thereby facilitating close contact between the connecting column 9 and the surface of the pipe 1, improving the convenience and efficiency of installation.
[0021] Further improvements, such as Figure 4 As shown: The heat tracing cable body 4 is sequentially arranged from the outside in, including an outer insulation layer 10, a metal braided mesh 12, a shielding layer 13, an inner insulation layer 14, and a self-regulating heat tracing core 15. A connecting wire 16 is provided on the side of the self-regulating heat tracing core 15. This multi-layered structure design ensures the safety and stability of the heat tracing cable body 4. The outer insulation layer 10 prevents external current from affecting the heat tracing cable; the metal braided mesh 12 enhances the mechanical strength of the heat tracing cable; the shielding layer 13 reduces electromagnetic interference; the inner insulation layer 14 protects the self-regulating heat tracing core 15; and the self-regulating heat tracing core 15 can automatically adjust the heating power according to the actual temperature, achieving energy saving and high efficiency.
[0022] Further improvements, such as Figure 3 As shown: The interior of the insulation sleeve 3 is provided with insulation filler 5, which further reduces the heat loss of the heat tracing cable body 4, improves the insulation effect, and thus reduces energy consumption.
[0023] Further improvements, such as Figure 4 As shown: The surface of the outer insulation layer 10 is provided with several sets of equally spaced color-changing strips 11. The color-changing strips 11 can intuitively display the working status of the heat tracing cable. For example, the strips change color when the temperature is too high, reminding the operator to check and deal with the problem in time, thus avoiding safety hazards caused by overheating.
[0024] Further improvements, such as Figure 1 As shown: The surface of the heat-insulating sleeve 3 is provided with several sets of windows. The window design facilitates the maintenance and repair of the heat tracing cable body 4, and also facilitates the observation of the changes in the color-changing strip 11.
[0025] Working principle: Based on the length and diameter of pipe 1, prepare a heating cable body 4 and an insulation sleeve 3 of appropriate length. Place the insulation sleeve 3 onto pipe 1 and fix it to the surface of pipe 1 using a fixing ring 17 and fixing bolts 7. The installation of the insulation sleeve 3 provides a good insulation environment for the heating cable body 4, reducing heat loss. For the installation of the heating cable body 4, wrap it around the surface of the connecting post 9, making it form a U-shaped serpentine distribution on the surface of pipe 1. Rotate the knob 8 on the connecting post 9 to ensure tight contact with the surface of pipe 1, ensuring the stability of the winding connection of the heating cable body 4. The U-shaped serpentine distribution increases the connection area between the heating cable body 4 and pipe 1, improving heating efficiency. Meanwhile, the knob 8 is designed for easy adjustment and fixation, ensuring the stability of the installation. Connect the connecting wire 16 of the heat tracing cable body 4 to the power supply and set a suitable heating temperature. Observe the color change of the color-changing strip 11 to ensure the normal operation of the heat tracing cable body 4. Adjust the heating power of the self-regulating heating element 15 according to actual needs to achieve energy saving and high efficiency. The self-regulating heating element 15 can automatically adjust the heating power according to the actual temperature, avoiding overheating and energy waste. Simultaneously, the color-changing strip 11 provides an intuitive indication of the working status, facilitating timely detection and handling of problems by operators. This utility model improves heating efficiency and reduces heat loss by improving the installation method and structural design of the heat tracing cable. The design of the knob 8 and the color-changing strip 11 enhances the convenience and safety of operation. The application of the self-regulating heating element 15 achieves energy saving and high efficiency, reduces operating costs, and the overall structure is compact and easy to install, suitable for various pipeline antifreeze scenarios.
