Description

Technical Field

[0001] This utility model relates to a comprehensive cable monitoring device, specifically a comprehensive cable monitoring device with temperature monitoring function. Background Technology

[0002] Communication cables are communication lines consisting of multiple insulated conductors forming a core, surrounded by a sealed sheath. Some also have an outer sheath. They are laid in various ways, including overhead, direct burial, duct, and underwater. Based on structure, they are classified as symmetrical, coaxial, and composite cables; based on function, they are classified as field cables and permanent cables (underground, submarine cables). Communication cables have a wide transmission bandwidth, large communication capacity, and are less susceptible to external interference, but are difficult to maintain. They can transmit telephone, telegram, data, and images.

[0003] High-voltage power cable joints often experience abnormally high temperatures due to joint damage, poor grounding, or other issues, which can easily lead to fires, explosions, and other accidents. Currently, temperature monitoring of power cable joints typically uses temperature-sensing optical fibers. These fibers are generally used for temperature measurement along the entire length of the power cable, but their positioning accuracy is around 0.5 meters, making it impossible to achieve full circumference measurement and thus unable to accurately measure overall temperature changes.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a comprehensive cable monitoring device with temperature monitoring function, characterized in that: it includes a monitoring box 1, the monitoring box 1 includes a monitor 2, a display 3 and a cooling fan 4, the display 3 is installed on the outside of the monitoring box 1, the monitor 2 includes a temperature sensor 5, a sensor assembly 6 and a cable connector 7, the temperature sensor 5 extends from the sensor assembly 6 and contacts the cable to be monitored; the cable connector 7 fixes the temperature sensor 5 to the sensor assembly 6, the monitor 2 also includes a first signal acquisition unit 8, a second signal acquisition unit 9 and a control unit 10, the control unit 10 includes a temperature analysis and processing module 11, an alarm module 12 and a power module 13, the temperature analysis and processing module 11 is electrically connected to the first signal acquisition unit 8, the second signal acquisition unit 9, the alarm module 12 and the power module 13 respectively, the cable connector 7 includes a buckle 14, a slot 15 and a fastening screw 16, and the cooling fan 4 is installed at the top and bottom of the monitoring box 1.

[0021] Specifically, both ends of the clip 14 are detachably and fixedly connected to the slot 15. The design of the slot 15, clip 14, and fastening screw 16 makes the installation and removal process between the cable connector 7 and the cable to be monitored more convenient and efficient. The user simply places the cable into the slot 15, then aligns the clip 14 with the slot 15 and gently snaps it in place, further tightening it with the fastening screw 16 to achieve a secure connection between the temperature sensor 5 and the cable. This design not only simplifies the installation steps and reduces operational difficulty but also effectively avoids problems such as poor contact or temperature measurement errors caused by improper installation.

[0022] Specifically, the cable connector 7 is also equipped with a waterproof sleeve 17, which, by providing a waterproof sleeve 17, ensures that...

[0023] Cable connector 7 maintains good performance even in harsh outdoor environments. The waterproof sleeve 17 is made of highly elastic, wear-resistant, and waterproof material, ensuring a tight fit between the cable and connector, effectively preventing rainwater, moisture, and other external water from entering and protecting internal electronic components from moisture damage. Furthermore, the waterproof sleeve 17 also possesses certain corrosion resistance, resisting the erosion of acids, alkalis, and other chemicals, extending the service life of cable connector 7.

[0024] Specifically, the temperature analysis and processing module 11 includes a signal amplification circuit 18 and a filter circuit 19, with the signal amplification circuit 18 and the filter circuit 19 connected together.

[0025] Specifically, a waterproof plate 20 is movably installed on the top of the monitoring box 1, and a sealing gasket 21 is provided between the waterproof plate 20 and the monitoring box 1. By incorporating the waterproof plate 20 and the sealing gasket 21, the waterproof performance and sealing of the monitoring box 1 are further enhanced when facing severe weather conditions. The waterproof plate 20 is made of lightweight and high-strength waterproof material, effectively resisting the direct impact of extreme weather such as strong winds and heavy rain on the monitoring box 1. Simultaneously, the waterproof plate 20 is designed for convenience, allowing it to be movably connected to the top of the monitoring box 1 via a pre-set slide rail or hinge, facilitating opening or closing by the user as needed for maintenance or inspection. The sealing gasket 21 is tightly fitted to the edge where the waterproof plate 20 contacts the monitoring box 1, forming a reliable waterproof barrier. This sealing gasket 21 is made of high-quality material resistant to aging and extreme temperatures, ensuring excellent sealing performance even after prolonged use, effectively preventing rainwater, dust, and other impurities from seeping into the monitoring box 1 and protecting the internal electronic equipment from damage.

[0026] Specifically, the temperature sensor 5 is model DS24B20.

[0027] A specific application example of this embodiment is as follows:

[0028] When using this device, the user first confirms the compatibility of the cable specifications to be monitored with the cable connector 7, and then properly places the cable into the slot 15. At this time, the cable sheath is tightly fitted with the anti-slip design inside the slot 15, ensuring that the cable will not shift due to external force during monitoring. Next, the user aligns one end of the buckle 14 with the opening of the slot 15, gently presses and slides it downwards until the other end of the buckle 14 is also fully engaged in the slot 15.

[0029] Once the cable connector 7 is securely connected to the cable, the temperature sensor 5 can accurately sense the temperature change on the cable surface and convert it into an electrical signal. These electrical signals are first amplified by the signal amplification circuit 18 to improve the accuracy and sensitivity of subsequent processing. Subsequently, the filtering circuit 19 filters the amplified signal to remove noise and interference components, ensuring that the data transmitted to the temperature analysis and processing module 11 is clean and accurate.

[0030] Upon receiving the filtered signal, the temperature analysis and processing module 11 immediately analyzes and calculates the current temperature of the cable. Simultaneously, this module compares this temperature value with a preset threshold. If the temperature exceeds the threshold, it indicates a potential risk of overheating, at which point the alarm module 12 is activated. The alarm module 12 emits an audible and visual alarm signal to alert the user and prompt appropriate action. Furthermore, the alarm information may be wirelessly transmitted to a remote monitoring center for timely access and handling by management personnel.

[0031] During monitoring, the cooling fan 4 runs continuously to dissipate the heat generated inside the monitoring enclosure 1 by the operation of electronic equipment. The fan's installation at the top and bottom of the monitoring enclosure 1 creates a good air convection channel, ensuring stable internal temperature. Simultaneously, the design of the waterproof plate 20 and sealing gasket 21 effectively prevents the intrusion of external moisture and dust, providing a good working environment for the electronic equipment.

[0032] In addition, this device also features data recording and query functions. Temperature data collected during monitoring is recorded in real-time in the storage unit, and users can view current and historical temperature data on display 3. This provides users with a convenient means of data analysis, helping them better understand the cable's operating status and take appropriate maintenance measures.
