Description

Technical Field

[0001] This utility model relates to the field of power line fault monitoring instruments, specifically a power line fault monitoring instrument with a hardware installation structure. Background Technology

[0002] A power line fault monitor is an electronic device that integrates special physical mounting devices. It is specifically designed to be installed on power transmission and distribution lines to monitor, locate, and diagnose faults in the power lines.

[0003] In the prior art, such as in the patent announcement number CN220671565U, a cable fault location monitoring device is disclosed. It includes a cable fault monitor with two fixed plates at its top and a rubber plate between the two fixed plates. Connecting straps are fixedly connected to both sides of the rubber plate. Auxiliary mechanisms are provided on both sides of the rubber plate. The auxiliary mechanisms include a storage frame, a connecting plate, a limiting rod, a limiting frame, and a pushing plate. The connecting straps are located inside the storage frame and are engaged with the storage frame through the limiting rods. The connecting plate is engaged with the storage frame through the limiting frame.

[0004] While the aforementioned patent utilizes the cooperation of a rubber sheet, storage frame, connecting plate, limiting rod, limiting frame, and pushing plate, with the connecting strap extending and retracting inside the storage frame, the connecting plate driving the limiting rod to limit the position of the connecting strap, and the limiting frame limiting the position of the connecting plate, thus facilitating the extension and retraction of the connecting strap for easy lifting and carrying of the cable fault monitor, it lacks a structure to ensure a stable and secure connection between the detection probe and the line. Displacement of the probe can affect the accuracy of sensor measurements. Furthermore, it lacks a structure to ensure a sufficient safe electrical distance between the device body and the line to prevent flashover. Therefore, to address these issues, a power line fault monitor with a hardware mounting structure is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as the lack of a structure to ensure a stable and secure connection between the detection probe and the line, which can lead to displacement affecting the accuracy of sensor measurements, and the lack of a structure to ensure sufficient safe electrical distance between the device body and the line to prevent flashover, this invention proposes a power line fault monitoring instrument with a hardware mounting structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The power line fault monitoring instrument with hardware installation structure of this utility model includes a monitoring instrument, a hinge is fixedly connected to the bottom of the back of the monitoring instrument in an axisymmetric manner, a telescopic component is fixedly connected to the top surface of the hinge, a positioning component is fixedly connected to the top of the telescopic component, a frame is fixedly connected to the top of the back of the monitoring instrument in an axisymmetric manner, and a rubber pad is fixedly connected to the side of the frame.

[0007] The telescopic assembly includes a base rod fixedly connected to the top surface of the hinge, an extension rod slidably connected inside the base rod, a top rod slidably connected inside the extension rod, and a plurality of positioning holes equally spaced from top to bottom on the surfaces of both the base rod and the extension rod. A sleeve hole is provided at the bottom end of both the extension rod and the top rod, and a spring is sleeved inside the sleeve hole. One end of the spring is fixedly connected to a limit bead, and the outer diameter of the top end of the base rod is interference-fitted with a rubber pad.

[0008] The positioning component includes a connecting plate fixedly connected to one end of the top rod. A wire groove is fixedly connected to the side of the connecting plate. A through threaded hole is opened on the side of the wire groove. An external threaded tube is threaded into the inside of the threaded hole. A rubber ring is sleeved inside the external threaded tube. A detection probe is set inside the rubber ring by interference fit.

[0009] Preferably, the limiting bead has an arc-shaped appearance, and the outer diameter of the arc matches the inner diameter of the limiting hole.

[0010] Preferably, the detection probe is used to contact the power line.

[0011] Preferably, the frame is used to limit and accommodate the telescopic component and the positioning component when the telescopic component is retracted.

[0012] Preferably, the spring is used to be compressed when the limiting bead disengages from the positioning hole and to rebound when the limiting bead aligns with the positioning hole, causing the limiting bead to engage with the positioning hole.

[0013] Preferably, the external threaded tube is used to move along the threaded hole during rotation and drive the detection probe to press against the power line.

[0014] The advantages of this utility model are:

[0015] 1. This utility model achieves a fast, secure, adjustable and non-loosening connection between the detection probe and the power line by using the groove of the positioning component to support the power line and by using the rotating external threaded tube to drive the detection probe inside, which is set by interference fit, to move along the threaded hole and press the power line. Combined with the buffering effect of the rubber ring, it effectively prevents the connection from loosening due to vibration or external force, ensuring the long-term stability of signal detection and the accuracy of measurement data.

[0016] 2. This utility model allows the telescopic and positioning components to be rotated and retracted into the frame via a hinge. A secure locking mechanism is achieved through the interference fit between the outer diameter of the bottom rod's top and the rubber pad fixed to the side of the frame. This results in a compact and small-sized device when folded, making it easy to carry and store. More importantly, it allows the telescopic components to be unfolded, keeping the wiring within the positioning components away from the monitoring device. This ensures physical isolation and a sufficient safe electrical distance between the device body and the power lines, effectively preventing flashover risks and improving the safety of the device in high-voltage environments.

[0023] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4As shown, a power line fault monitoring instrument with hardware installation structure includes a monitoring instrument 1. A hinge 2 is fixedly connected to the bottom of the back of the monitoring instrument 1 in an axisymmetric manner. A telescopic component 3 is fixedly connected to the top surface of the hinge 2. A positioning component 4 is fixedly connected to the top of the telescopic component 3. A frame 5 is fixedly connected to the top of the back of the monitoring instrument 1 in an axisymmetric manner. A rubber pad 6 is fixedly connected to the side of the frame 5.

[0025] The telescopic assembly 3 includes a bottom rod 31 fixedly connected to the top surface of the hinge 2. An extension rod 32 is slidably connected inside the bottom rod 31. A top rod 33 is slidably connected inside the extension rod 32. Several positioning holes are equidistantly opened from top to bottom on the surfaces of the bottom rod 31 and the extension rod 32. A sleeve hole is opened at the bottom end of the extension rod 32 and the top rod 33. A spring 34 is sleeved inside the sleeve hole. One end of the spring 34 is fixedly connected to a limit bead 35. The outer diameter of the top end of the bottom rod 31 is interference-fitted with the rubber pad 6.

[0026] During operation, during the inspection process, the operator pulls the bottom rod 31, which is fixedly connected to the top surface of the hinge 2, outward. This causes the telescopic component 3 and its top positioning component 4 to rotate and extend away from the main body of the monitor 1 via the hinge 2. Next, the operator pulls the extension rod 32 inside the bottom rod 31 and the top rod 33 inside the extension rod 32 outward in sequence. During this pulling process, the limiting bead 35, fixedly connected to one end of the spring 34, is compressed and retracts into the sleeve hole, compressing the spring 34. When the limiting bead 35 moves to the positioning hole position on the surface of the bottom rod 31 or the extension rod 32, the spring 34 rebounds, causing the limiting bead 35 to engage in the positioning hole, completing the extension and locking process. Through this multi-stage adjustable extension design, the telescopic component 35 can ultimately be extended further. The connecting plate 41 fixedly connected to one end of the top rod 33 and the wire groove 42 on its side are positioned away from the main body shell of the monitor 1. At this time, when the power line to be monitored is placed inside the wire groove 42 and comes into contact with the detection probe 45, the physical extension structure formed by the telescopic component 3 forcibly establishes and maintains a sufficient and defined spatial distance between the high-voltage live parts of the monitor 1 and the live power line carried in the wire groove 42. This remote isolation structure, which is actively realized in the detection working state, effectively prevents flashover accidents that may be caused by the monitor 1 accidentally approaching the high-voltage line, and significantly improves the inherent safety of the equipment in high-voltage environment detection operations.

[0027] Furthermore, the positioning component 4 includes a connecting plate 41 fixedly connected to one end of the top rod 33. A wire groove 42 is fixedly connected to the side of the connecting plate 41. A through threaded hole is opened on the side of the wire groove 42. An external threaded tube 43 is threadedly connected inside the threaded hole. A rubber ring 44 is sleeved inside the external threaded tube 43. A detection probe 45 is set inside the rubber ring 44 through an interference fit.

[0028] During operation, after the power line is placed inside the cable groove 42 in the positioning assembly 4, the operator inserts the detection probe 45 into the rubber ring 44 fitted inside the external threaded tube 43. Initial positioning is achieved through the interference fit between the rubber ring 44 and the outer diameter of the detection probe 45. Subsequently, the detection probe 45 is rotated. Due to the friction of the interference fit, the detection probe 45 drives the rubber ring 44 and the external threaded tube 43, which are in close contact with it, to rotate together. The external threaded tube 43 and the threaded hole on the side of the cable groove 42 form a threaded pair, and the rotational motion is converted into the axial movement of the external threaded tube 43, the internal rubber ring 44, and the detection probe 45 as a whole. As the external threaded tube 43 continues to be screwed in, the detection probe 45... The probe 45 is forcefully pushed until its tip is firmly and stably pressed against the surface of the power line inside the slot 42. During this process, the rubber ring 44 provides elastic deformation, which not only enhances the clamping force to prevent the probe 45 from loosening, but also buffers possible external impacts. This dual locking mechanism based on threaded advancement and elastic clamping ensures that the probe 45 and the surface of the live power line under test maintain highly reliable and vibration-resistant physical contact and electrical connection during the detection process. This ensures that the electrical signal of the power line fault is completely and accurately picked up and transmitted to the internal circuit of the monitor 1 for analysis and diagnosis, directly improving the accuracy and reliability of fault location and diagnosis.

[0029] Furthermore, the limiting bead 35 has an arc-shaped appearance, and the outer diameter of the arc matches the inner diameter of the limiting hole;

[0030] During operation, when the length of the telescopic component 3 needs to be adjusted, the operator manually pulls the extension rod 32 or the top rod 33 inside the base rod 31 fixedly connected to the top surface of the hinge 2. During the pulling process, the limiting bead 35 fixedly connected to one end of the spring 34, due to its unique arc-shaped appearance, allows its outer surface to smoothly slide over the edge of the positioning hole on the surface of the base rod 31 or the extension rod 32. At this time, the limiting bead 35 is forced to retract inward into the sleeve hole and compress the spring 34. This action allows the extension rod 32 or the top rod 33 to slide freely. When the rod moves to the target position, that is, the arc-shaped outer diameter of the limiting bead 35 is precisely aligned with the positioning. When the hole is opened, the compressed spring 34 instantly rebounds, and its elasticity pushes the arc-shaped surface of the limiting bead 35 to fit perfectly into the inner diameter of the positioning hole, forming a stable mechanical lock. This self-centering design using the arc-shaped surface and the round hole ensures that the limiting bead 35 can quickly, accurately and reliably engage with the positioning hole. Even in a vibrating environment, the maximum contact area between the matching arc-shaped outer diameter and the inner diameter of the limiting hole can provide stronger resistance to displacement, effectively preventing the rod from accidentally retracting or extending. This ensures that the telescopic component 3 maintains the preset safe extension length during the inspection operation, reliably isolates the high-voltage line from the monitoring instrument 1 body, and avoids the risk of flashover.

[0031] Furthermore, the frame 5 is used to limit and accommodate the telescopic component 3 and the positioning component 4 when the telescopic component 3 is retracted;

[0032] During operation, after completing the power line monitoring, the operator first fully retracts the telescopic component 3 and folds the entire component upwards by rotating the hinge 2. At this time, the retracted telescopic component 3, together with the positioning component 4 fixedly connected to its top, is accurately embedded into the frame 5, which is symmetrically fixed to the top of the back of the monitor 1. The inner contour of the frame 5 closely fits the shape of the component in the retracted state, achieving rigid physical constraint on all moving parts of the telescopic component 3 and the positioning component 4, completely limiting any swaying or displacement. At the same time, when the bottom rod 31 rotates with the hinge 2 to the retracted end point, its top outer diameter forms an interference fit with the rubber pad 6 fixed to the side of the frame 5, generating a frictional locking force, further enhancing the fixing effect. This retractable design dominated by the frame 5 makes the equipment structure compact and easy to carry.

[0033] Working principle: When power line fault monitoring is required, the operator first moves the bottom rod 31 of the telescopic assembly 3, which is fixedly connected to the top surface of the hinge 2, outward, causing it to rotate around the axis of the hinge 2 and unfold to a horizontal working position. At this time, the top of the bottom rod 31 disengages from the interference fit with the rubber pad 6 fixedly connected to the side of the frame 5. Then, according to the required safe distance between the on-site line and the main body of the monitoring instrument 1, the extension rod 32 located inside the bottom rod 31 and the top rod 33 located inside the extension rod 32 are pulled outward in sequence. During the pulling process, the limiting bead 35, which is fixedly connected to one end of the spring 34, is compressed and retracts into the sleeve hole due to its arc-shaped outer diameter contacting the edge of the positioning hole on the surface of the bottom rod 31 or the extension rod 32, thus compressing the spring 34. When the extension rod 32 or the top rod 33 moves to the target position and the limiting bead 35 is aligned with the positioning hole, the spring 34 rebounds and pushes the arc-shaped outer diameter of the limiting bead 35 to accurately engage with the inner diameter of the positioning hole, completing the length locking. Through this process... The telescopic adjustment ultimately moves the positioning component 4, which is fixedly connected to the end of the top rod 33, and the power line it carries, to a safe position away from the main body shell of the monitor 1, forming a reliable spatial isolation barrier between the high-voltage live line and the low-voltage electronic components of the monitor 1, effectively preventing the risk of flashover. Then, the power line to be tested is placed in the wire groove 42 on the side of the connecting plate 41 of the positioning component 4. Next, the detection probe 45 is inserted into the rubber ring 44 sleeved inside the external thread tube 43 through an interference fit, and the external thread tube 43 is screwed into the threaded hole opened on the side of the wire groove 42. During the rotation, the external thread tube 43 moves downward along the thread, pushing the detection probe 45, which is fixed inside by the rubber ring 44 through the interference fit, to continuously feed into the wire groove 42 until its end tightly presses against the surface of the power line, achieving stable signal acquisition. After the test is completed, the reverse operation is performed to retract the components, and finally the telescopic component 3 and the positioning component 4 are stored and locked in the frame 5.
