Description

Technical Field

[0001] This application relates to the field of cable fixing equipment technology, specifically to a mounting flange for a temperature measuring cable. Background Technology

[0002] In numerous fields such as industrial production, power transmission, building fire protection, and environmental monitoring, temperature sensing cables, as a key device with distributed temperature measurement capabilities, have been widely and significantly applied to achieve real-time temperature monitoring and anomaly early warning for specific areas or equipment. Compared to traditional single-point temperature sensors, temperature sensing cables can achieve continuous temperature monitoring along the cable length, providing a wider coverage area. They can promptly detect local temperature anomalies along the cable, effectively reducing the risk of safety accidents caused by localized overheating and ensuring the stable operation of related systems. As the application scenarios of temperature measuring cables continue to expand, their operating environments are becoming increasingly complex. In some applications, temperature measuring cables need to be laid over long distances or withstand certain external tensile forces, such as the pulling force generated during cable installation or the continuous tension caused by environmental factors during long-term use. To prevent these external forces from causing problems such as breakage, displacement, or performance damage to the internal temperature measuring core of the cable, existing technologies typically incorporate tensile steel wire ropes inside the temperature measuring cable. These tensile steel wire ropes are generally made of high-strength metal and extend along the length of the temperature measuring cable. They can effectively withstand externally applied tensile loads, transferring the tension primarily to themselves, thus providing reliable protection for the fragile temperature measuring core and ensuring that the temperature measuring cable can maintain its normal temperature measuring function under stress. However, in actual installation and application, the existing temperature measuring cable's structural design has a significant technical flaw: its installation end cannot form an effective connection with the internal tensile steel wire rope. Specifically, when workers install and fix the temperature measuring cable at the target monitoring position, they usually need to connect and fix the cable to the external installation structure through the connector at the installation end to ensure the stability of the cable installation. However, in the existing design, the connector at the installation end is only connected to the outer sheath of the temperature measuring cable or part of the non-load-bearing structure, and does not establish a firm and reliable mechanical connection with the internal steel wire rope that plays the main tensile role. As a result, after installation and fixing, the external installation structure cannot transfer the cable's tension to the tensile steel wire rope through the connector. Summary of the Invention

[0016] Please refer to Figure 1-4This embodiment provides a mounting flange for a temperature measuring cable, including a base 100. The base 100 has a coaxial through hole 110 inside and a stepped structure outside, including a coaxial major diameter and a minor diameter. The through hole 110 is a tapered hole, with a relatively larger inner diameter at the end near the major diameter. A core block 200 is frustum-shaped, with the same slope as the through hole 110. The core block 200 has a through hole 210 inside for the cable core to pass through, and a corresponding groove 220 on the outside corresponding to the wire rope. An end cap 300 is detachably mounted on the base 100 to press the core block 200 into the through hole 110. The end cap 300 also has a coaxial clearance hole 310 for the temperature measuring cable to pass through.

[0017] In this embodiment, the base 100 has a stepped structure. Its small diameter is used for insertion and installation with fixed objects such as walls, and the installation method is an interference fit. Its large diameter is located outside the fixed object and is used to install the end cap, thereby pressing the core block 200 into the through hole 110.

[0018] In this embodiment, the temperature measuring cable enters the interior of the base 100 through the clearance hole 310; the cable core extends to the outside of the base 100 through the through hole 210 for connection with an external signal receiving device; the wire rope is clamped between the slot 220 and the base 100. Since the core block 200 and the through hole 110 are inclined, the core block 200 can be locked to the wire rope simply by pressing the core block 200 with the end cap 300.

[0019] In a preferred embodiment, the minor diameter has a variable diameter structure, with the diameter near the major diameter end being relatively larger.

During installation, the sealing ring is first installed in the installation groove, and then the end cap 300 is pressed onto the substrate 100 to form a sealed connection. With the cooperation of the sealing between the temperature measuring cable and the end cap 300, the temperature measuring cable can be sealed and installed.

[0030] In a preferred embodiment, it further includes a docking plate 140 for fitting and installing with the small diameter; the docking plate 140 is annular and has through second lifting holes 141 on both sides of the small diameter.

[0031] An interference fit can be formed between the mating plate 140 and the minor diameter, so that the base 100 can be lifted through the second lifting hole 141 on the mating plate 140.

[0032] In a preferred embodiment, the outer wall of the core block 200 is further provided with a ventilation groove 230; the ventilation groove 230 is located between the two slots 220, and its extension direction is parallel to the extension direction of the slots 220.
