Description

Technical Field

[0001] This utility model relates to the field of electric heat tracing technology, specifically a metal armored electric heat tracing cable with a multi-layer protective structure. Background Technology

[0002] Electric heating tape consists of a conductive polymer, two parallel metal wires, and an insulating sheath. Its key features include a high positive temperature coefficient of the conductive polymer, and the parallel connection of the wires allows for automatic adjustment of output power based on temperature changes in the heated system. It automatically limits the heating temperature, can be cut to any length or extended within a certain range, and allows for multiple overlaps without the risk of overheating or burning. Electric heating tape is commonly used for insulation and freeze protection of industrial and agricultural pipelines. Workers lay and secure the heating tape to the pipeline, where it generates heat to insulate and prevent freezing.

[0003] However, existing electric heating cables have the following problems when installed in pipelines: To ensure the tightness and stability of the electric heating cable's attachment to the pipeline, workers usually need to use ropes or wires to bind the cable to the pipeline. However, directly binding the cable with ropes or wires can easily damage the cable's outer layer, affecting its service life. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a metal armored electric heating cable with a multi-layer protective structure, which solves the technical problem that in order to ensure the tightness and stability of the electric heating cable's attachment to the pipeline, workers usually need to use ropes or steel wires to bind the electric heating cable to the pipeline. However, the method of directly binding the electric heating cable with ropes or steel wires can easily damage the surface of the electric heating cable and affect its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal armored electric heating cable with a multi-layer protective structure, comprising an electric heating cable body and a sliding restraint and protection assembly installed on the electric heating cable body. The sliding restraint and protection assembly includes guide vanes and a sliding adjustment ring slidably disposed on the guide vanes. The sliding adjustment ring includes contact vanes, sleeves, and elastic pressure plates. The surface of the contact vanes is machined with wiring grooves. The sleeves are divided into two sets and connected to both ends of the contact vanes. The two sets of sleeves are respectively fitted onto the two sets of guide vanes. The elastic pressure plates are divided into two sets and respectively installed on the two sets of sleeves. The sleeves are provided with insertion slots. The elastic pressure plates are used in conjunction with the insertion slots. The bottom of the electric heating cable body is equipped with a heat-retaining insulating pad. The surface of the heat-retaining insulating pad is machined with several sets of strip-shaped heat-retaining grooves, and the interior of the strip-shaped heat-retaining grooves is machined with several sets of heat-retaining holes.

[0006] In a preferred embodiment of this invention, the contact blade has an arc-shaped structure and the same curvature as the surface of the electric heating cable.

[0007] In a preferred embodiment of this utility model, the contact blade, the sleeve, and the heat-insulating pad are all made of thermally conductive silicone material, and the thickness of the contact blade, the sleeve, and the heat-insulating pad is 5mm-8mm.

[0009] In a preferred embodiment of this utility model, several groups of heat-gathering holes are distributed in a honeycomb pattern and are evenly distributed within the strip-shaped heat-gathering groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the structure of existing electric heating cables by equipping them with a sliding restraint and protection component. The electric heating cable is laid on the pipe surface, and the position of the sliding restraint and anti-slip component is adjusted according to the restraint position. The rope or steel wire is directly restrained to the sliding restraint and anti-slip component, avoiding direct contact between the rope or steel wire and the surface of the electric heating cable, thereby achieving the purpose of protecting the electric heating cable. In addition, a heat-retaining pad is designed at the contact point between the electric heating cable and the pipe. On the one hand, it can prevent the electric heating cable from directly contacting the rust on the pipe, reducing corrosion of the electric heating cable. On the other hand, it can achieve the purpose of heat retention, improving the heat preservation effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 1-3 This utility model provides a technical solution: a metal armored electric heating cable with a multi-layer protective structure, including an electric heating cable body 1 and a sliding restraint protection assembly installed on the electric heating cable body. The sliding restraint protection assembly includes guide vanes 2 and a sliding adjustment ring slidably disposed on the guide vanes 2. The guide vanes 2 are made of soft rubber material. The sliding adjustment ring includes contact vanes 3, sleeves 4 and elastic pressure plates 5. The surface of the contact vanes 3 is machined with a wiring groove 6. The sleeves 4 are divided into two sets and connected to both ends of the contact vanes 3. The two sets of sleeves 4 are respectively fitted onto the two sets of guide vanes 2. The elastic pressure plates 5 are divided into two sets and respectively installed on the two sets of sleeves 4. The sleeves 4 are provided with insertion ports 7. The elastic pressure plates 5 are used in conjunction with the insertion ports 7. The bottom of the electric heating cable body 1 is equipped with a heat-concentrating insulating pad 8. The surface of the heat-concentrating insulating pad 8 is machined with several sets of strip-shaped heat-concentrating grooves 9. The interior of the strip-shaped heat-concentrating grooves 9 is machined with several sets of heat-concentrating holes 10.

[0020] Further improvements, such as Figure 1 As shown, the contact blade 3 has an arc-shaped structure and the same curvature as the surface of the electric heat tracing cable body 1, and moves along the electric heat tracing cable body 1.

[0021] Further improvements, such as Figure 1 As shown, the contact blade 3, the sleeve 4, and the heat-concentrating insulating pad 8 are all made of thermally conductive silicone material. The thickness of the contact blade 3, the sleeve 4, and the heat-concentrating insulating pad 8 is 5mm-8mm. The actual thickness can be selected according to the usage requirements. The thermally conductive silicone material has good thermal conductivity, is soft in texture, and is easy to deform along with the laying of the electric heating cable body 1.

[0022] Further improvements, such as Figure 1As shown, the elastic pressure plate 5 includes a metal spring 11 and an insert rod 12 fixed inside the metal spring 11. The insert rod 12 passes through the insertion port 7 and abuts against the guide vane 2. The metal spring 11 presses down on the insert rod 12, and the insert rod 12 is inserted into the through port 7 and abuts against the guide vane 2, thereby achieving the purpose of positioning the sliding adjustment ring.

[0023] Specifically, several sets of heat-gathering holes 10 are distributed in a honeycomb pattern and are evenly distributed in the strip-shaped heat-gathering groove 9. This design can effectively improve the heat-gathering effect of the heat-gathering pad 8 and ensure the heat insulation effect of the pipeline.

[0024] During use: Before laying the electric heating cable body 1 on the pipe, the operator moves the sliding adjustment ring to the position where it needs to be secured. After adjustment, the metal spring 11 presses down the insertion rod 12, which is inserted into the through hole 7 and abuts against the guide vane 2, thereby achieving the purpose of positioning the sliding adjustment ring. Then, the operator secures the rope along the cable tray 6 and fixes the electric heating cable body 1 to the pipe surface, completing the non-contact fixation of the electric heating cable. At the same time, a heat-concentrating pad 8 is designed at the contact point between the electric heating cable and the pipe. On the one hand, it can prevent the electric heating cable from directly contacting the rust on the pipe, reducing corrosion of the electric heating cable. On the other hand, it can achieve the purpose of heat concentration and improve the insulation effect.
