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.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a pressure-conducting pipe electric heat tracing acquisition device with multi-station sensing, including a control box 1, a wiring panel 2, a connecting frame 3, a sensor probe 4, a connecting plate 5, a binding strap 6, a positioning buckle 7, a connecting line 8, a docking port 9, a limiting slide 10, a heating element 11, a heat insulation sleeve 12, and a positioning frame 13.

The probe part of the sensor probe 4 is close to the outer wall of the pressure guide tube. The binding strap 6 is inserted into the positioning buckle 7. There are two positioning buckles 7.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, place the connecting plate 5 at a suitable position on the pressure guide tube, pass the binding strap 6 through the connecting plate 5, and insert both ends of the binding strap 6 into the two positioning buckles 7 to tie and fix it, so that the connecting plate 5 is firmly attached to the surface of the pressure guide tube. Connect one end of the connecting frame 3 to the bottom end of the control box 1 and fix it, and the other end to the rectangular mounting bracket of the sensor probe 4. Then install the connecting frame 3 on the surface of the connecting plate 5, ensuring that the probe part of the sensor probe 4 passes through the preset mounting hole of the connecting plate 5 and the probe is close to the outer wall of the pressure guide tube.

[0037] Take the insulation sleeve 12 and partially wrap it around the pressure guide tube. Slide the limiting slide 10 into the groove on the outer wall of the insulation sleeve 12. Engage the heating element 11 with the limiting slide 10. Then, insert the docking port 9 through the limiting slide 10 and align it with the insert on one side of the heating element 11. Figures 1-3 As shown, the positioning brackets 13 symmetrically installed on the outside of the insulation sleeve 12 are slid to make the insulation sleeve 12 and the positioning brackets 13 form a ring that is sleeved on the outside of the pressure guide tube, thus completing the installation and fixing of the insulation sleeve 12 and the heating element 11. One end of the connecting wire 8 is connected to the wiring panel 2 on one side of the control box 1, and the other end is connected to the heating element 11 through the docking port 9 to realize the circuit conduction and complete the installation of the entire device.

[0038] The wiring panel 2 is connected to the connecting wire 8, and one end of the connecting wire 8 is provided with a docking port 9. The docking port 9 passes through the limiting slide 10, and the inner wall surface of the limiting slide 10 is provided with an arc-shaped sliding groove that matches the heating element 11. The docking port 9 is connected to the insert on one side of the heating element 11, and the heating element 11 and the limiting slide 10 are snapped together. A heat insulation pad is provided between the heating element 11 and the limiting slide 10, and the limiting slide 10 is set with a C-shaped structure. The limiting slide 10 slides on the surface of the insulation sleeve 12, and a positioning frame 13 is symmetrically installed on the outer side of the insulation sleeve 12. The outer wall surface of the insulation sleeve 12 is provided with a sliding groove that matches the limiting slide 10, and the C-shaped structure of the insulation sleeve 12 and the limiting slide 10 are sleeved together. The positioning frame 13 is provided with a threaded groove, and the positioning frame 13 is made of high-temperature resistant plastic material.

[0039] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, when the control box 1 is started, its built-in control circuit begins to work. The temperature sensor probe 4 and the pressure sensor probe 4 are close to the outer wall of the pressure guide tube to collect the temperature and pressure data of different positions of the pressure guide tube in real time. The data is transmitted to the control circuit in the control box 1 through electrical connection. The control circuit receives and analyzes the collected data. If the temperature of the pressure guide tube is lower than the set value, it will issue a command to control the heating element 11 to start working through the connecting wire 8. The heating element 11 is attached to the pressure guide tube for heat tracing.

[0040] The position of the heating element 11 can be adjusted by sliding the limiting slider 10 on the surface of the insulation sleeve 12 to ensure heating of key parts of the pressure guide tube. The insulation sleeve 12 partially covers the pressure guide tube to reduce heat loss and improve heating efficiency.

[0041] When the temperature of the pressure guide tube reaches the set value, the control circuit issues a command to stop the heating element 11 from working, thereby achieving precise temperature control. The communication module inside the control box 1 transmits the collected temperature and pressure data and device operating status information to external devices in real time, which facilitates remote monitoring and management by staff and ensures stable operation of the device.

[0042] 1. Control box; 2. Wiring panel; 3. Connector frame; 4. Sensor probe; 5. Connecting plate; 6. Restraint strap; 7. Positioning buckle; 8. Connecting wire; 9. Dating port; 10. Limit slider; 11. Heating element; 12. Insulation sleeve; 13. Positioning frame.

[0043] Working principle: When using the pressure-conducting pipe electric heat tracing acquisition device with multi-position sensing, the device is fixed to the surface of the pressure-conducting pipe by the binding strap 6 and positioning buckle 7 on the connecting plate 5 to ensure the stability of the overall structure. The wiring panel 2 on one side of the control box 1 is connected to the heating element 11 through the connecting line 8, and the docking port 9 is docked with the plug on one side of the heating element 11 to realize the circuit conduction.

[0044] When the control circuit receives the temperature data from the sensor probe 4, if the temperature is lower than the set value, it will issue a command to make the heating element 11 work. The heating element 11 is engaged with the limiting slide 10. The limiting slide 10 slides on the surface of the insulation sleeve 12 to adjust the position of the heating element 11, ensuring that it heats the key parts of the pressure guide tube. The positioning frame 13 on the outside of the insulation sleeve 12 slides so that the insulation sleeve 12 and the positioning frame 13 form a ring that is sleeved on the outside of the pressure guide tube. The heating element 11 in the positioning frame 13 adheres to the pressure guide tube to achieve heat tracing. Since the insulation sleeve 12 partially wraps the tube, heat loss is reduced and heating efficiency is improved.

[0045] The control box 1, as the core control unit, houses the control circuitry and is responsible for coordinating all functions of the device. Temperature and pressure sensor probes 4 penetrate the connecting plate 5 through pre-drilled mounting holes, close to the outer wall of the pressure-conducting pipe, enabling real-time acquisition of temperature and pressure data at different positions within the pipe. This data is transmitted to the control circuitry within the control box 1 via the electrical connection between the sensor probes 4 and the control box 1, providing a basis for subsequent electric heat tracing regulation.

[0046] When the temperature of the pressure-conducting tube reaches the set value, the control circuit will control the heating element 11 to stop working, achieving precise temperature control. At the same time, the communication module in the control box 1 can transmit the collected temperature and pressure data and device operating status information to external devices, facilitating remote monitoring and management and increasing the overall practicality.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
