Description

Technical Field

[0001] This utility model relates to the field of power equipment condition monitoring technology, specifically to a wireless temperature measuring device for cable intermediate joints. Background Technology

[0002] In power system operation, electrical equipment joints serve as critical nodes for energy transmission, and their operating temperature directly reflects the equipment's health status. Abnormal temperature rises can occur when joints experience poor contact, oxidation corrosion, or overload. Failure to monitor this in time can lead to insulation aging, short circuits, or even fires. Therefore, online temperature monitoring of electrical equipment joints is of great significance. Currently, commonly used temperature measurement technologies include contact and non-contact methods. Among these, infrared thermography is widely used in electrical equipment condition monitoring due to its advantages such as non-contact operation, fast response, and remote monitoring capabilities.

[0003] Existing infrared temperature measurement devices face numerous technical bottlenecks in practical applications: the installation structure is prone to slippage under cable vibration or thermal expansion and contraction, causing the relative position of the temperature probe and the measured connector to shift, affecting monitoring accuracy; the sealing structure often employs a simple design, which is susceptible to corrosion of the connector due to moisture infiltration after long-term use, affecting heat dissipation and increasing contact resistance; some device adjustment mechanisms are prone to failure due to mechanical wear during long-term operation, making it impossible to achieve continuous and stable temperature measurement, while electric drive structures suffer from high power consumption and complex structures; in addition, the metal casing of traditional devices is prone to heat accumulation, causing a deviation between the actual and measured temperatures of the connector, failing to accurately reflect the equipment's operating status. Summary of the Invention

[0004] This utility model provides a wireless temperature measurement device for cable intermediate joints. The device achieves convenient installation and flexible adaptation through a splicing structure design. With reasonable temperature monitoring and power supply design, it can accurately monitor the joint temperature. In addition, the buffer device and mesh plate enhance the structural stability, protection performance and heat dissipation, so as to comprehensively ensure the safety of cable operation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A wireless temperature measuring device for a cable joint includes a cable, a first sleeve, and a second sleeve. The first sleeve and the second sleeve are of a spliced ​​structure and are connected by threads and fitted onto the outer wall of the cable joint. A temperature monitor is installed on the first sleeve, and a battery box is installed on the second sleeve. A buffer device is installed on the inner side of the first sleeve and the second sleeve.

[0007] In a preferred embodiment, both the first sleeve and the second sleeve are assembled from an upper splice and a lower splice. The end of the upper splice is provided with a retaining rail, and the end of the lower splice is correspondingly provided with a retaining groove. The upper splice and the lower splice are slidably inserted into each other through the retaining rail and the retaining groove.

[0008] In a preferred embodiment, after the first sleeve is spliced ​​together, a threaded connector is formed at the end, and after the second sleeve is spliced ​​together, a corresponding threaded groove is formed at the end. The first sleeve and the second sleeve are threadedly connected through the threaded connector and the threaded groove.

[0009] In a preferred embodiment, the sides of the first sleeve and the second sleeve are provided with mesh plates.

[0010] In a preferred embodiment, an annular conductive sheet is provided at the side connection between the first sleeve and the second sleeve. A conductive wire is embedded inside the first sleeve and connects the temperature monitor and the conductive sheet. A conductive wire is embedded inside the second sleeve and connects the battery box and the conductive sheet.

[0011] In a preferred embodiment, the buffer device includes an airbag, which is attached to the inner wall of the first sleeve and the second sleeve; an inflation hole is provided on the outer wall of the first sleeve and the second sleeve and communicates with the airbag, and an air valve is provided on the inflation hole.

[0012] In a preferred embodiment, the bottom surface of the temperature monitor extends through the first sleeve and the air bladder, and a temperature sensing element is provided on its bottom surface, which is tightly fitted to the outer wall of the intermediate connector.

[0013] A wireless temperature measuring device for cable joints, the advantages of which are:

[0014] 1. The first and second sleeves adopt a splicing structure, and their upper and lower splicing parts are slidably inserted through rails and slots. The first and second sleeves are connected by a threaded connector and a threaded groove. This design makes installation and disassembly of the device more convenient, flexibly adaptable to different specifications of cable intermediate joints, effectively improving installation efficiency, reducing operational difficulty, and facilitating later maintenance and repair.

[0015] 2. A temperature monitor is installed on the first sleeve, and a battery box is installed on the second sleeve. The two are connected by a ring-shaped conductive plate at the side connection and an internally embedded conductive wire to ensure a stable power supply to the temperature monitor. The temperature sensor at the bottom of the temperature monitor can fit tightly against the outer wall of the cable joint, enabling accurate and real-time monitoring of the joint temperature and timely detection of abnormal temperatures, thus providing a reliable guarantee for the safe operation of the cable.

[0016] 3. The buffer device installed inside the first and second sleeves includes an airbag attached to the inner wall. The airbag can be inflated through the inflation hole and air valve. The inflated airbag can effectively buffer external impact force, protect the cable intermediate joint from mechanical damage, and enhance the fit and stability between the device and the cable intermediate joint. The mesh plate installed on the side can increase the structural strength and heat dissipation performance of the device to a certain extent, ensuring the stable operation of the device in complex environments.

Detailed Implementation

[0026] like Figure 1 and Figure 2As shown, a wireless temperature measuring device for a cable joint includes a cable 1, a first sleeve 2, and a second sleeve 3. The first sleeve 2 and the second sleeve 3 adopt a spliced ​​structure, and after being assembled by threaded connection, they are tightly fitted onto the outer wall of the cable joint 9, achieving a stable installation of the temperature measuring device. A temperature monitor 4 installed on the first sleeve 2 is used to monitor the temperature of the cable joint 9 in real time, while a battery box 5 on the second sleeve 3 provides power to the entire device. Buffer devices are installed on the inner sides of the first sleeve 2 and the second sleeve 3 to effectively reduce external impacts on the cable joint 9, ensuring its normal operation.

[0027] Preferred solutions include Figure 3 As shown, both the first sleeve 2 and the second sleeve 3 are assembled from an upper splicing component 6-1 and a lower splicing component 6-2. The upper splicing component 6-1 has a retaining rail 7 at its end, and the lower splicing component 6-2 has a corresponding retaining groove 8 at its end. During installation, the retaining rail 7 of the upper splicing component 6-1 is slidably inserted into the retaining groove 8 of the lower splicing component 6-2. Through the cooperation of the retaining rail 7 and the retaining groove 8, the upper splicing component 6-1 and the lower splicing component 6-2 are quickly positioned and initially fixed, facilitating subsequent assembly operations.

[0028] Preferred solutions include Figure 4 As shown, after the first sleeve 2 is assembled, a threaded connector 11 is naturally formed at the end. After the second sleeve 3 is assembled, a matching threaded connection groove 12 is formed at the end. The threaded connector 11 of the first sleeve 2 is screwed into the threaded connection groove 12 of the second sleeve 3. Through the tight engagement of the threads, a firm connection between the first sleeve 2 and the second sleeve 3 is achieved, ensuring the overall stability of the device structure.

[0029] Preferred solutions include Figure 4 As shown, mesh panels 10 are installed on the sides of the first sleeve 2 and the second sleeve 3. The mesh panels 10 are made of flexible, corrosion-resistant material and are installed on the sides of the sleeves in a certain fixing manner. They not only help dissipate heat inside the device and create a good environmental condition for stable operation of the device, but also prevent small animals from crawling into the device and damaging the cable intermediate joint 9 and the internal structure of the device.

[0030] Preferred solutions include Figure 2 and Figure 4 As shown, an annular conductive sheet 17 is provided at the side connection between the first sleeve 2 and the second sleeve 3. A conductive wire is pre-embedded inside the first sleeve 2, with one end connected to the temperature monitor 4 and the other end connected to the annular conductive sheet 17. Similarly, a conductive wire is pre-embedded inside the second sleeve 3, with one end connected to the battery box 5 and the other end connected to the annular conductive sheet 17. When the first sleeve 2 and the second sleeve 3 are connected by threads, the annular conductive sheets 17 adhere to each other and conduct electricity, forming a complete circuit between the battery box 5 and the temperature monitor 4, thus powering the temperature monitor 4.

[0031] Preferred solutions include Figure 4 and Figure 5 As shown, the buffer device includes an airbag 13 attached to the inner walls of the first sleeve 2 and the second sleeve 3. An inflation hole 15 is provided on the outer wall of the first sleeve 2 and the second sleeve 3, which communicates with the interior of the airbag 13. An air valve 16 is installed on the inflation hole 15 to control the inflow and outflow of gas. When the first sleeve 2 and the second sleeve 3 are fitted onto the outside of the intermediate connector 9, an appropriate amount of gas is injected into the airbag 13 through the air valve 16, causing the airbag 13 to inflate and tightly fit against the cable intermediate connector 9, thus providing a buffering and shock-absorbing effect. When it is necessary to disassemble the device, the air valve 16 is opened to release the gas inside the airbag 13, facilitating disassembly.

[0032] Preferred solutions include Figure 6 As shown, the bottom surface of the temperature monitor 4 extends through the first sleeve 2 and the air bladder 13, and a temperature sensing element 14 is installed on its bottom surface. During the installation process, by adjusting the positions of the first sleeve 2 and the second sleeve 3, the temperature sensing element 14 is ensured to be in close contact with the outer wall of the cable intermediate joint 9, thereby accurately acquiring the joint temperature data and transmitting the data to the temperature monitor 4 in real time for processing and display.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
