[0001] This invention relates to the field of electric heat tracing technology, and more particularly to a series constant power electric heat tracing cable with an installation ring. Background Technology

[0002] Electric heating tape is a new type of high-tech product. Since its introduction into the application field in the 1970s, it has been widely used for the antifreeze and insulation of liquids transported in pipelines and tanks, maintaining process temperatures, and heating roads, ramps, pedestrian crossings, eaves, and floors. Electric heating tapes are generally divided into parallel electric heating tapes and series electric heating tapes. In series electric heating tapes, the resistance wires are connected in series, resulting in continuous and uniform heat generation throughout the tape. The core wires have the same current and equal resistance, and the entire heating tape heats up evenly from beginning to end, making it more suitable for heat tracing and insulation of long-distance pipelines.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0028] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0029] See Figures 1-6 A series constant power electric heating cable with an installation ring includes a pipe 1, a heating cable 2 disposed on the outside of the pipe 1, a fixing member 3 disposed on the outside of the pipe 1, an installation member 4 disposed on the outside of the heating cable 2, and a binding strap 5 disposed inside the installation member 4 for fixing the heating cable 2.

[0030] After the heating cable 2 is installed on the outer wall of the pipe 1, it is fixed by the binding strap 5 and the installation part 4. Then, the installation part 4 is fixed to the pipe 1 by the fixing part 3 to realize the connection between the heating cable 2 and the pipe 1. By setting multiple sets of equidistant fixing parts 3 and installation parts 4 on the outside of the pipe 1, the connection effect is firm and it is convenient for users to carry out large-area installation operations. It can effectively avoid the situation where the connection between the heating cable 2 and the pipe 1 is loose and falls off, resulting in poor heating effect.

[0031] refer to Figure 6 As shown, the heat tracing cable 2 includes a wear-resistant layer 201, an insulating layer 202 is fixedly sleeved on the inner wall of the wear-resistant layer 201, two sets of heating wires 203 are sleeved on the inner wall of the insulating layer 202, a thermally conductive silicon pad 204 is fixedly sleeved on the outer wall of the heating wires 203, a copper foil 205 is fixedly sleeved on the outer wall of the thermally conductive silicon pad 204, and a graphite coating 206 is provided on the outer wall of the copper foil 205.

[0032] The wear-resistant layer 201 improves the wear resistance of the heat tracing cable 2, preventing scratches when using the heat tracing cable 2 in harsh environments. It also transfers heat to the copper foil 205 through the thermally conductive silicone pad 204. The graphite coating 206 improves the thermal conductivity between the thermally conductive silicone pad 204 and the copper foil 205. The thermally conductive silicone pad 204 allows for sufficient contact and heat conduction between the two sets of heating wires 203 and the copper foil 205, thereby enabling the heat generated by the heating wires 203 to be fully transferred to the pipe 1.

[0033] In the specific implementation process, such as Figure 2 and Figure 4 As shown, the fastener 3 includes a fixing ring 31 disposed on the outside of the pipe 1. A connecting ring 32 is fixedly connected to one side of the fixing ring 31. A connecting plate 33 is inserted inside the connecting ring 32. A connecting strap 34 is fixedly connected to one side of the connecting plate 33. Insert rods 35 are slidably disposed at the top and bottom of the connecting plate 33. Insert holes 36 that cooperate with the insert rods 35 are opened at the top and bottom of the inner wall of the connecting ring 32.

[0034] Mounting component 4 includes a connecting seat 41 disposed at one end of the connecting strap 34. A mounting ring 42 is fixedly connected to one side of the connecting seat 41. A pair of positioning blocks 43 are integrally disposed on the top of the mounting ring 42. Both sides of the positioning blocks 43 are provided with through grooves 44 for use with the binding strap 5. One end of the binding strap 5 is fixedly installed at the bottom of the connecting seat 41, and the other end of the binding strap 5 is inserted into the top of the connecting seat 41 and extends outward from one side.

[0035] The retaining ring 31 and the mounting ring 42 are elastic components.

[0036] It should be noted that the fixing ring 31 and the mounting ring 42 are made of plastic and have a certain degree of elasticity. They can be directly clipped onto the outside of the pipe 1 and the heat tracing cable 2. The binding strap 5 is wrapped around the outside of the pipe 1 and then inserted into the through groove 44 inside the positioning block 43. One end is then inserted into the connecting seat 41 to bind and fix the heat tracing cable 2. The connecting plate 33 at one end of the connecting strap 34 is inserted into the connecting ring 32 on one side of the fixing ring 31. The two inserts 35 at the top and bottom of the connecting plate 33 are inserted into the insertion holes 36 inside the connecting ring 32, thereby quickly connecting and fixing the connecting seat 41.

[0037] refer to Figure 2 As shown, a pair of limiting blocks 6 are integrally provided on the top of the fixing ring 31. Bolts 7 are provided inside the pair of limiting blocks 6. After the fixing ring 31 is stuck on the outside of the pipe 1 and the heat tracing cable 2, the heat tracing cable 2 is limited by the limiting blocks 6, and the two limiting blocks 6 are connected and fixed by the bolts 7.

[0038] refer to Figure 3As shown, a rotating rod 8 is rotatably connected to the inner wall of the connecting plate 33, and a double-headed cam 9 is fixedly connected to the outer side of the rotating rod 8. A movable plate 10 is fitted to both the top and bottom of the double-headed cam 9. The outer side of the movable plate 10 is fixedly connected to one end of the insertion rod 35. A spring 11 is sleeved on the outer side of the insertion rod 35, and a rotating block 12 is fixedly connected to the other end of the rotating rod 8.

[0039] The rotating block 12 drives the rotating rod 8 to rotate, causing the double-headed cam 9 to rotate from a vertical state to a horizontal state. This causes the spring 11 to recover its elasticity, driving the two insert rods 35 to move towards the moving plate 10. The insert rods 35 retract into the connecting plate 33, separating the insert rods 35 from the insertion hole 36, thereby releasing the fixation of the connecting plate 33 and facilitating the disassembly of the connecting seat 41.

[0040] refer to Figure 5 As shown, a rotating shaft 13 is rotatably provided on the inner wall of the connecting seat 41 near the binding strap 5. A screw 14 is screwed to one side of the connecting seat 41. A clamping block 15 is rotatably provided at one end of the screw 14. The outer side of the clamping block 15 is slidably connected to the inner wall of the connecting seat 41. One side of the clamping block 15 abuts against one side of the binding strap 5. A knob 16 is fixedly connected to one end of the screw 14.

[0041] After the restraint strap 5 is inserted into the connecting seat 41, the heat tracing cable 2 is fixed by pulling the restraint strap 5. When the restraint strap 5 is pulled, the rotating shaft 13 rotates accordingly, which improves the smoothness of pulling the restraint strap 5. The screw 14 is rotated by the knob 16, so that the clamping block 15 moves laterally in the connecting seat 41 to clamp and fix the restraint strap 5.

[0042] In use, the fixing ring 31 and the mounting ring 42 are secured to the outside of the pipe 1 and the heat tracing cable 2. The binding strap 5 is wrapped around the outside of the pipe 1 and then inserted into the through groove 44 inside the positioning block 43. One end is then inserted into the connecting seat 41. After the binding strap 5 is inserted into the connecting seat 41, the heat tracing cable 2 is fixed by pulling the binding strap 5. The screw 14 is rotated by the knob 16, causing the clamping block 15 to move laterally in the connecting seat 41 to clamp and fix the binding strap 5. The connecting plate 33 at one end of the connecting strap 34 is inserted into the connecting ring 32 on one side of the fixing ring 31. The two inserts 35 at the top and bottom of the connecting plate 33 are inserted into the insertion holes 36 inside the connecting ring 32, thereby quickly connecting and fixing the connecting seat 41, thus achieving the installation connection between the heat tracing cable 2 and the pipe 1. Finally, the user can connect the power supply to the heat tracing cable 2.
