Description

Technical Field

[0001] This utility model relates to the field of cable monitoring equipment technology, and in particular to a monitoring device for monitoring the service status of cables. Background Technology

[0002] In fields such as power transmission, industrial control, and communication networks, cables serve as the core carriers of energy and signal transmission, and their operational stability directly determines the reliability of the entire system. Cable joints, as critical nodes in cable connections, must fulfill multiple functions, including conductor conductivity, insulation protection, and environmental sealing.

[0003] When cable monitoring equipment monitors cable heads, the sensor can be installed in either a contact or non-contact manner. For contact sensors, the installation structure is mostly fixed. However, since the cable joint and surrounding cable will inevitably move slightly due to changes in ambient temperature or external forces, there is a risk that the sensor may detach from the cable head when the cable moves slightly. Utility Model Content

[0004] Therefore, it is necessary to provide a monitoring device for monitoring the service status of cables, which addresses the problem that cable joints and surrounding cables may inevitably experience slight movements due to changes in ambient temperature or external forces, and the risk of fixed-installation sensors detaching from the cable joints when the cables move slightly.

[0005] A monitoring device for monitoring the service status of cables includes: a monitoring unit for monitoring cable joints, the monitoring unit including a lower shell and an upper shell, the upper shell and the lower shell being bolted to the outside of the cable joint, a temperature sensor being disposed inside the upper shell above the cable joint, and an auxiliary component being disposed inside the upper shell such that the temperature sensing element at the bottom of the auxiliary temperature sensor is always in contact with the outer arc surface of the cable joint.

[0006] The auxiliary component has fastening components on both sides, located inside the upper shell, for securing the cable.

[0007] In one embodiment, the auxiliary component includes a mounting plate, the bottom end of the temperature sensor penetrates the surface of the mounting plate and is fixedly mounted thereon, the top connecting wire of the temperature sensor penetrates the top surface of the upper shell and is connected to an external device, and compression springs are provided on the top surfaces of both sides of the mounting plate, and the compression springs are fixedly mounted to fastening components provided on both sides respectively.

[0008] In one embodiment, the fastening assembly includes pressure blocks located on both sides of the auxiliary assembly. The opposing sidewalls of the two sets of pressure blocks are provided with grooves. The end of the mounting plate is slidably disposed inside the grooves. The top ends of the compression springs disposed on the top surfaces of both ends of the mounting plate are fixedly installed with the inner top surfaces of the grooves.

[0009] In one embodiment, the bottom end of the temperature sensor is pressed against the cable connector by a compression spring.

[0010] In one embodiment, the fastening assembly further includes a threaded rod, the bottom end of which is rotatably connected to the top end of the lower pressure block, the top end of which penetrates the top surface of the upper shell and is connected to the fastening head, and the outer arc surface of the threaded rod is rotatably connected to the top surface of the upper shell.

[0011] In one embodiment, guide blocks are provided on both sides of the lower pressure block, and guide grooves are provided on the inner wall of the upper shell, with the ends of the guide blocks slidably disposed inside the guide grooves.

[0012] In one embodiment, the bottom surface of the lower pressure block that contacts the cable is provided with an installation groove. The installation groove is provided with an ejector spring. The end of the ejector spring is connected to a stop post. The bottom end of the stop post penetrates the bottom surface of the lower pressure block and abuts against the cable. The outer arc surface of the stop post that contacts the cable is provided with an anti-slip pad.

[0013] In one embodiment, a support block is provided inside the lower shell at a position corresponding to the lower pressure block, and a sealing ring is provided inside the side wall of the lower shell and the upper shell that is in contact with the cable.

[0014] Beneficial effects

[0015] 1. By setting auxiliary components to assist the temperature sensor, the bottom end of the temperature sensor is always in contact with the outer wall of the cable connector inside the lower and upper shells. When the cable connector and surrounding cables inevitably move slightly due to changes in ambient temperature or external forces, the mounting plate is pressed downward by the elastic force of the compression springs set at both ends. This causes the temperature sensing element at the bottom end of the temperature sensor fixed inside the mounting plate to fit against the outer wall of the cable connector, reducing the risk of the temperature sensor detaching from the cable connector and ensuring the stability of the monitoring data.

[0016] 2. At the same time, retractable abutments are provided on the bottom surfaces of the pressure blocks on both sides of the mounting plate where they contact the cable, so as to fix cables of different diameters. When the cable is too thin, the pressure block and the support block are in contact and cannot fix the cable. The retractable abutments at the bottom of the pressure block are squeezed and fixed by the elastic force of the push-out spring, which further increases the applicability of this utility model.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined with Figures 1-5 This invention describes a monitoring device for monitoring the service status of cables.

[0027] In one embodiment, a monitoring device for monitoring the service status of cables includes: a monitoring device 100 for monitoring cable joints, the monitoring device 100 including a lower shell 101 and an upper shell 102, the upper shell 102 and the lower shell 101 being bolted to the outside of the cable joint, a temperature sensor 111 being disposed inside the upper shell 102 above the cable joint, and an auxiliary component 112 being disposed inside the upper shell 102, wherein the temperature sensing element at the bottom of the auxiliary temperature sensor 111 is always in contact with the outer arc surface of the cable joint.

[0028] The auxiliary component 112 has fastening components 105 located inside the upper shell 102 on both sides for fastening the cable;

[0029] Temperature sensor 111 is installed inside mounting plate 113, and the bottom end of temperature sensor 111 is always in contact with the outer arc surface of cable connector below under the action of auxiliary component 112. When the cable connector and surrounding cables inevitably move slightly due to changes in ambient temperature or external force, temperature sensor 111 is pressed by auxiliary component 112 to keep the temperature sensing element at the bottom end of temperature sensor 111 in constant contact with cable connector, thereby reducing the risk of temperature sensor 111 detaching from cable connector.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary component 112 includes a mounting plate 113. The bottom end of the temperature sensor 111 passes through the surface of the mounting plate 113 and is fixedly mounted to the mounting plate 113. The top connecting wire of the temperature sensor 111 passes through the top surface of the upper shell 102 and is connected to an external device. Compression springs 114 are provided on the top surfaces of both sides of the mounting plate 113. The compression springs 114 are fixedly mounted to the fastening components 105 provided on both sides respectively.

[0031] In this embodiment, fastening components 105 are respectively provided on both sides of the mounting plate 113. Compression springs 114 provided on the top surfaces of both ends of the mounting plate 113 are respectively connected to the fastening components 105. When the cable connector or cable moves under external force, the temperature sensor 111 installed inside the mounting plate 113 is always in contact with the outer wall of the cable connector under the compression of the compression springs 114, thereby reducing the risk of the temperature sensor 111 detaching from the cable connector.

[0032] like Figure 3 , Figure 4 and Figure 5The fastening assembly 105 shown includes a lower pressure block 108, which is located on both sides of the auxiliary assembly 112. The two sets of lower pressure blocks 108 have grooves 115 on their opposite sidewalls. The end of the mounting plate 113 is slidably disposed inside the groove 115. The top ends of the compression springs 114 disposed on the top surfaces of both ends of the mounting plate 113 are fixedly installed with the inner top surface of the groove 115. The bottom end of the temperature sensor 111 is squeezed against the cable connector under the compression of the compression springs 114.

[0033] The fastening assembly 105 also includes a threaded rod 107, the bottom end of which is rotatably connected to the top end of the lower pressure block 108. The top end of the threaded rod 107 passes through the top surface of the upper shell 102 and is connected to the fastening head 106. The outer arc surface of the threaded rod 107 is rotatably connected to the top surface of the upper shell 102. Guide blocks 110 are respectively provided on the two side walls of the lower pressure block 108. A guide groove 109 is provided on the inner wall of the upper shell 102. The end of the guide block 110 is slidably disposed inside the guide groove 109.

[0034] In this embodiment, pressing blocks 108 are respectively provided on both sides of the mounting plate 113. The opposite sidewalls of the two sets of pressing blocks 108 are provided with grooves 115. The two ends of the mounting plate 113 are slidably disposed inside the grooves 115, and the top of the compression spring 114 is fixedly installed with the inner top surface of the groove 115, thereby ensuring that the temperature sensor 111 installed inside the mounting plate 113 and the cable connector are mutually pressed and abutted.

[0035] Meanwhile, threaded rods 107 are rotatably installed at the top of the two sets of lower pressure blocks 108. The top of the threaded rods 107 passes through the top surface of the upper shell 102 and is connected to the fastening head 106. The operator places the cable connector on the lower shell 101 and then uses bolts to fix the upper shell 102 to the lower shell 101. By rotating the fastening head 106, the operator drives the lower pressure block 108 to descend, pressing down and fastening the cables at both ends of the cable connector. The temperature sensor 111 inside the support block 103 set between the two sets of lower pressure blocks 108 is driven down. The temperature sensing element at the bottom of the temperature sensor 111 comes into contact with the cable connector. The connecting wire at the top of the temperature sensor 111 passes through the top of the upper shell 102 and is connected to the external equipment. The temperature sensor 111 is used to monitor the cable connector during use.

[0036] Guide blocks 110 are provided at both ends of the lower pressure block 108. The ends of the guide blocks 110 are slidably disposed inside the guide grooves 109 opened on the inner wall of the upper shell 102. The guide grooves 109 restrict the direction and distance of the lower pressure block 108 when it rises and falls, thereby increasing the stability of the lower pressure block 108 in securing the cable.

[0037] like Figure 4 and Figure 5As shown, the bottom surface of the lower pressure block 108 that contacts the cable is provided with an installation groove 116. Inside the installation groove 116, there are ejector springs 117 respectively. The ends of the ejector springs 117 are connected to the abutment posts 118. The bottom ends of the abutment posts 118 all penetrate the bottom surface of the lower pressure block 108 and abut against the cable. The outer arc surface of the abutment posts 118 that contacts the cable is provided with an anti-slip pad.

[0038] In this embodiment, an installation groove 116 is provided on the bottom surface of the lower pressure block 108 that contacts the cable. An ejector spring 117 is provided inside the installation groove 116. The end of the ejector spring 117 is connected to the abutment post 118. The ejector spring 117 pushes the abutment post 118 outward. When it is necessary to tighten cables of different diameters, the lower pressure block 108 descends under the action of rotating threaded rod 107, and squeezes and tightens the cables at both ends of the cable joints of different diameters fixed inside the lower shell 101 and the upper shell 102. The outer arc surface of the abutment post 118 is provided with an anti-slip pad. The abutment post 118 is pushed out under the elastic force of the ejector spring 117, and squeezes and fixes cables of different diameters. The anti-slip pad at the end of the abutment post 118 increases the friction between the abutment post 118 and the cable, further increasing the applicability of this utility model.

[0039] like Figure 2 As shown, a support block 103 is provided inside the lower shell 101 at a position corresponding to the lower pressure block 108, and a sealing ring 104 is provided inside the side wall of the lower shell 101 and the upper shell 102 that is in contact with the cable.

[0040] In this embodiment, a support block 103 is provided inside the lower shell 101 at a position corresponding to the lower pressure block 108. The support block 103 supports the cable fixed between the lower shell 101 and the upper shell 102, so that the lower pressure block 108 inside the upper shell 102 can press down and tighten the cables on both sides of the cable joint. A sealing ring 104 is provided inside the side wall of the lower shell 101 and the upper shell 102 that is in contact with the cable. At the same time, a sealing gasket is provided between the side wall of the lower shell 101 and the upper shell 102 that is in contact with the cable. The sealing ring 104 prevents external rainwater from entering the lower shell 101 and the upper shell 102, thereby affecting the service life of the internal cable joint.

[0041] Working principle: In use, the lower shell 101 and the upper shell 102 are fitted onto the outside of the cable connector using bolts. After tightening, the operator rotates the fastening head 106 to drive the threaded rod 107 to rotate. The threaded rod 107 drives the lower pressure block 108 to descend, pressing down and tightening the cables on both sides of the cable connector. During the process of the lower pressure block 108 being driven down by the threaded rod 107, the guide blocks 110 on both sides of the lower pressure block 108 slide down along the inner wall of the guide groove 109. The temperature sensing element at the bottom of the temperature sensor 111 installed inside the mounting plate 113 between the two sets of lower pressure blocks 108 is pressed and contacted with the cable connector. The connecting wire at the top of the temperature sensor 111 passes through the top surface of the upper shell 102 and connects to the external equipment. The temperature sensor 111 monitors the cable connector during use.

[0042] When the cable joint or surrounding cable moves slightly under the action of external force, the temperature sensor 111 inside the upper shell 102 is pressed by the compression springs 114 at both ends of the internal mounting plate 113, which keeps pressing the mounting plate 113 down, so that the temperature sensing element at the bottom of the temperature sensor 111 is pressed and contacted with the cable joint, thereby reducing the risk of the temperature sensor 111 detaching from the cable joint.

[0043] When installing cables with different diameters at both ends of the cable joint, the bottom end of the lower pressure block 108 and the retractable abutment 118 are ejected outward under the elastic force of the ejection spring 117. The abutment 118 squeezes the cable, and at the same time, the anti-slip pad on the outer arc surface of the abutment 118 increases the friction with the outer arc surface of the cable, thereby ensuring the stability of the cable fastening.

[0044] It should be noted that the temperature sensor 111 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the temperature sensor 111 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
