Description

Technical Field

[0001] The utility model relates to the technical field of cable fault early warning, in particular to a cable fault early warning device. Background Art

[0002] During operation, the cable generates heat due to the large current flowing through the core. Monitoring the temperature of the cable can not only obtain the working condition of the cable insulation, but also understand the line operation status by calculating the current carrying capacity of the line. Currently, the most widely used cable temperature measurement method is distributed optical fiber temperature measurement. Based on the measured temperature, the current carrying capacity of the cable can be calculated to further obtain the cable operation information. The temperature measuring optical fiber can be laid inside the cable sheath, that is, built-in type; it can also be laid outside the cable sheath along the line, that is, external type.

[0003] In the prior art, infrared temperature measuring and warning instruments are often used to detect and warn of high temperatures when cables are working. However, this is generally done by contacting the outer surface of the cable with a handheld temperature probe, and then performing temperature measurement and warning on the cable. If there is no measure to position the temperature probe, the temperature probe is not only easily separated from the contact part of the cable, but also affects the accuracy of the cable temperature measurement and warning. Although some devices can perform temperature measurement and warning on cables by clamping the cable, they can generally only perform temperature measurement and warning on cables with the same outer diameter. When encountering cables with other outer diameters, it is often difficult for the temperature probe to contact the cable, resulting in poor applicability of the existing devices.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a cable fault warning device, comprising a base 1 and an infrared temperature measuring warning instrument 2, the infrared temperature measuring warning instrument 2 is fixed to the left side of the upper end of the base 1, a V-shaped support plate 3 is arranged on the right side of the infrared temperature measuring warning instrument 2, a V-shaped clamping plate 4 is arranged above the V-shaped support plate 3, a storage groove 14 is opened at the top of the V-shaped clamping plate 4, a temperature measuring probe 15 is arranged in the storage groove 14, a spring cable 9 is connected to the upper end of the temperature measuring probe 15, a support block 5 is fixed to the left side of the V-shaped support plate 3, a clamping height adjustment component is arranged at the upper end of the support block 5, the clamping height adjustment component comprises an adjusting block 6, a threaded lifting rod 7 and a guide rod 8, the adjusting block 6 is fixed to the left side of the V-shaped clamping plate 4, the threaded lifting rod 7 is rotatably connected to the upper end of the support block 5, and the threaded lifting rod 7 is threaded upward to penetrate the adjusting block 6, the guide rod 8 is fixed to the upper end of the support block 5, and the guide rod 8 slides upward to penetrate the adjusting block 6.

[0022] When the temperature of the cable is measured and warned by the warning device, the threaded lifting rod 7 is turned and the adjusting block 6 is driven to slide up and down along the guide rod 8. During this process, the adjusting block 6 will drive the V-shaped clamping plate 4 and the temperature measuring probe 15 to move up and down together, and the temperature measuring probe 15 will continuously stretch the spring cable 9, which is conducive to ensuring the normal up and down movement of the temperature measuring probe 15. Therefore, by adjusting the distance between the V-shaped clamping plate 4 and the V-shaped support plate 3, the cable is placed between the V-shaped clamping plate 4 and the V-shaped support plate 3, and then the V-shaped clamping plate 4 and the V-shaped support plate 3 cooperate to clamp cables of different outer diameters, so as to perform temperature measurement and warning for cables of different outer diameters.

[0023] In this example, an adjusting shaft 13 is fixed to the upper end of the temperature measuring probe 15, and the adjusting shaft 13 slides upward and passes through the V-shaped clamping plate 4, and an adjusting plate 11 is fixed to the upper end of the adjusting shaft 13, and a threaded adjusting rod 12 is rotatably connected to the upper end of the V-shaped clamping plate 4, and the threaded adjusting rod 12 threadedly passes through the adjusting plate 11 upward, and a through hole 16 communicating with the storage groove 14 is opened at the upper end of the V-shaped support plate 3, and the spring cable 9 extends out of the V-shaped support plate 3 through the through hole 16, and the end of the spring cable 9 is connected to the infrared temperature measuring warning instrument 2.

[0024] When the cable is clamped, the threaded adjustment rod 12 is turned to drive the adjustment plate 11 to move up and down, and the adjustment plate 11 will drive the adjustment shaft 13 and the temperature measuring probe 15 to move up and down together, so the upper and lower use positions of the temperature measuring probe 15 can be conveniently adjusted, and the adjustment plate 11, the adjustment shaft 13 and the temperature measuring probe 15 are driven downward by the rotation of the threaded adjustment rod 12 until the temperature measuring probe 15 contacts the cable surface, thereby facilitating the temperature measuring probe 15 to stably contact the cable surface. Since the temperature measuring probe 15 is connected to the infrared temperature measuring early warning instrument 2 through the spring cable 9, combined with the work of the infrared temperature measuring early warning instrument 2, it is conducive to accurate temperature measurement and early warning of cable faults, and it is also conducive to temperature measurement and early warning of cables of different outer diameters through the temperature measuring probe 15. There is no need to manually hold the temperature measuring probe 15 for temperature measurement and early warning work, and the operation is convenient.

[0025] In this example, a support shaft 10 is fixed to the right side of the upper end of the base 1 , and the V-shaped support plate 3 is rotatably connected to the upper end of the support shaft 10 .

[0026] The V-shaped support plate 3 is supported by the support shaft 10. Since the V-shaped support plate 3 is rotatably connected to the upper end of the support shaft 10, when the cable rotates accidentally, the V-shaped support plate 3 will be driven to rotate on the support shaft 10, which is beneficial to reduce the torque force applied to the cable when it rotates accidentally and is beneficial to protecting the cable from force release.

[0027] Working principle:

[0028] Twist the threaded lifting rod 7 and drive the adjustment block 6 to slide up and down along the guide rod 8. The adjustment block 6 will drive the V-shaped clamping plate 4 and the temperature measuring probe 15 to move up and down together, so as to adjust the distance between the V-shaped clamping plate 4 and the V-shaped support plate 3. Place the cable between the V-shaped clamping plate 4 and the V-shaped support plate 3, and then twist the threaded adjustment rod 12 to drive the adjustment plate 11, the adjustment shaft 13 and the temperature measuring probe 15 to move downward until the temperature measuring probe 15 contacts the surface of the cable. Combined with the work of the infrared temperature measuring early warning instrument 2, a temperature measurement early warning of the cable fault is performed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
