[0001] This utility model relates to the technical field of electric heat tracing devices, specifically to an electric heat tracing device with a temperature acquisition structure. Background Technology
[0002] Electric heat tracing devices are insulation equipment that converts electrical energy into heat energy. They are mainly used for freezing, insulation, and process temperature maintenance of pipelines, tanks, or instruments. Their core consists of heating cables and insulation layers. After being energized, they generate heat evenly to prevent the medium from freezing or to maintain a specific temperature. They are widely used in industrial fields such as petroleum, chemical, and construction, as well as in civilian applications, and are characterized by safety, energy saving, and a high degree of automation.
[0003] Traditional electric heat tracing devices do not have the function of collecting pipeline temperature. When the temperature rises and power needs to be cut off, it is mostly done manually. The timeliness of power cutting is poor, which can easily lead to excessive waste of electricity. Utility Model Content

Detailed Implementation
[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] like Figures 1-7 As shown, this utility model provides an electric heat tracing device with a temperature acquisition structure, including a connecting rope 1, a temperature acquisition mechanism 2 at one end of the connecting rope 1, and an electric heat tracing mechanism 3 at the end of the connecting rope 1 away from the temperature acquisition mechanism 2.
[0026] The temperature acquisition mechanism 2 includes a control box 21, which is fixedly installed at the end of the connecting rope 1. A dust cover 22 is fixedly installed at the bottom of the control box 21, and a rubber frame 221 is fixedly connected to the bottom of the dust cover 22. An infrared temperature sensor 222 is fixedly installed on the top of the inner wall of the dust cover 22, and a nylon strap 23 and a frame 24 are fixedly installed on the outer wall of the dust cover 22. The infrared temperature sensor 222 is used to detect the temperature of the outer wall of the pipe. Since the conveying pipe is mostly made of metal, the heat transfer efficiency is high. When the medium temperature rises, the infrared temperature sensor 222 can quickly detect it and feed the temperature data back to the controller. When the temperature exceeds the threshold, the controller immediately shuts off the heating element 372 to achieve timely power-off, reduce energy consumption, and avoid the problem of overheating affecting the medium quality. It is worth noting that the controller can be installed inside the cavity of the control box 21. The temperature sensor 222 and the controller are commercially available devices that can be purchased by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate further on them. Furthermore, this solution aims to protect the physical structure, not the circuitry or software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge. The dust cover 22 provides dust protection for the infrared temperature sensor 222 by relying on the outer wall of the pipe, ensuring the effectiveness of temperature detection. The rubber frame 221 enhances the sealing between the dust cover 22 and the outer wall of the pipe.
[0027] Furthermore, such as Figure 2 , Figure 3 As shown, the nylon strap 23 is movably inserted into the inner cavity of the frame 24. A bolt 25 is threadedly connected to the outer wall of the frame 24. The threaded end of the bolt 25 extends into the inner cavity of the frame 24 and is rotatably connected to a pressure block 26. A limit rod 27 is fixedly installed on the outer wall of the pressure block 26. The limit rod 27 is slidably connected to the frame 24. When installing the dust cover 22, first clean the outer wall of the pipe, then attach the dust cover 22 to the outer wall of the pipe. Next, wrap the nylon strap 23 around the pipe and insert it into the inside of the frame 24. Then rotate the bolt 25 to move the pressure block 26 in the inner cavity of the frame 24 to secure the nylon strap 23, thus completing the installation of the dust cover 22. The limit rod 27 is used to limit the translation of the pressure block 26.
[0028] Furthermore, such as Figure 5 , Figure 6As shown, the electric heat tracing mechanism 3 includes a splicing ring 31, a connecting block 32 fixedly installed on the outer wall of the splicing ring 31, a rotating block 33 rotatably connected to the inner wall of the connecting block 32, a splicing ring 34 fixedly installed at the end of the rotating block 33, one end of the connecting rope 1 fixedly installed on the outer wall of the splicing ring 34, an assembly block 35 fixedly installed on the outer wall of the splicing ring 34, a pin groove provided on the outer wall of the assembly block 35, an assembly block 36 fixedly installed on the outer wall of the splicing ring 31, a pin 361 slidably connected to the inner wall of the assembly block 36, an elastic element 362 fixedly installed on the outer wall of the pin 361, and the end of the elastic element 362 away from the pin 361 fixedly connected to the outer wall of the assembly block 36. The design of block 32 and rotating block 33 allows for a rotatable connection between splicing ring 1 31 and splicing ring 2 34, facilitating user assembly and disassembly of splicing ring 1 31 and splicing ring 2 34 on the outer wall of the pipe. During installation, splicing ring 1 31 is placed against the outer wall of the pipe, and splicing ring 2 34 is rotated. This pre-pulls pin 361. After splicing ring 2 34 rotates into position, assembly block 1 35 moves to the side of assembly block 2 36, releasing pin 361. The elastic force of elastic element 362 allows pin 361 to be inserted into the pin groove of assembly block 1 35, thus completing the installation of splicing ring 1 31 and splicing ring 2 34. This design enhances the ease of assembly and disassembly.
[0029] Furthermore, such as Figure 7 As shown, strip frames 37 are fixedly installed on the sides of splicing ring 31 and splicing ring 34. An aluminum foil layer 371 is fixedly connected to the inner wall of the strip frame 37. An electric heating element 372 is fixedly installed between the two sides of the inner wall of the strip frame 37. When the electric heating element 372 is working, it can convert electrical energy into heat to heat the conveying pipeline. Through the design of the aluminum foil layer 371, the heat radiation generated by the electric heating element 372 can be reflected onto the pipeline, thereby improving the heat utilization rate of the electric heating element 372.
[0030] The working principle of this type of electric heat tracing device with a temperature acquisition structure will be explained in detail below.
[0031] like Figures 1-7As shown, during installation, firstly, the outer wall of the pipe is cleaned. Then, the splicing ring 31 is attached to the outer wall of the pipe. Next, the splicing ring 34 is rotated, and the pin 361 is pre-pulled. After the splicing ring 34 rotates into place, the assembly block 35 moves to the side of the assembly block 36. Then, the pin 361 is released, and through the elastic force of the elastic element 362, the pin 361 can be inserted into the pin groove of the assembly block 35, thus completing the installation of the splicing ring 31 and the splicing ring 34. Then, the dust cover 22 is attached to the outer wall of the pipe, and then the nylon... The nylon tape 23 is wrapped around the pipe and inserted into the inside of the frame 24. Then, the bolt 25 is rotated, which moves the pressure block 26 in the inner cavity of the frame 24 to secure the nylon tape 23, thus completing the installation of the dust cover 22. In use, the electric heating element 372 is controlled to work, which can convert electrical energy into heat to heat the conveying pipe. The infrared temperature sensor 222 is used to detect the temperature of the outer wall of the pipe. The infrared temperature sensor 222 will feed back the temperature data to the controller. After the threshold is exceeded, the controller will immediately turn off the electric heating element 372 to realize the function of timely power cut-off.
