Description

Technical Field

[0001] This invention relates to the field of fuse testing technology, specifically to an intelligent testing device for outdoor fuses. Background Technology

[0002] The online intelligent monitoring device for fuses adopts a modular design, offering strong compatibility and convenience. It requires no large-scale modification to the existing power system; simple installation on traditional fuse carriers allows for rapid intelligent upgrades. This online open circuit monitoring device can monitor the status of PT fuses in real time. By sampling point by point, it analyzes whether the three-phase voltage difference exceeds a set threshold to determine whether the A, B, and C phase PT fuses are open. The device consists of a controller and voltage sensors. The controller includes a power supply module, a data processing module, a display module, and a communication module for data processing and control.

[0003] In practical use, the clamping mechanism usually uses a lead screw to drive the clamping component to tighten the outer wall of the fuse tube; this clamping force is mainly maintained by the frictional resistance between the lead screw and the thread. When the fuse is subjected to overvoltage, the electric field at the end is concentrated, which easily generates corona and high-frequency resonance; after long-term use, the terminal contact surface oxidizes, and the contact resistance increases after energization, generating electromagnetic micro-vibration and gap discharge, which causes high-frequency vibration. The fuse fixing screw is prone to loosening under high-frequency vibration, resulting in a decrease in the friction between the lead screw and the thread, causing the detection device to fall off. To address the above problems, this invention is proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an intelligent detection device for outdoor fuses, including a detector, an arc-shaped plate rotatably connected to the side wall of the detector, and a fastener fixedly connected to the side wall of the arc-shaped plate, and further including: The pressure mechanism is fixedly installed on the top of the detector. The pressure mechanism includes a housing fixedly connected to the top of the detector. A threaded rod is slidably connected to the inner wall of the through hole of the housing. A limit rod is fixedly connected to the inner wall of the housing. A sliding rod is fixedly connected to the inner wall of the housing. The fixing mechanism is slidably disposed on the inner wall of the outer shell cavity. The fixing mechanism includes a sliding plate slidably connected to the inner wall of the outer shell cavity, a fixing ring fixedly connected to the outer wall of the threaded rod, and a spring fixedly connected to the side wall of the sliding plate. The limiting mechanism is fixedly installed on the inner wall of the cavity of the outer shell; The outer wall of the fixed ring is rotatably connected to the inner wall of the groove of the sliding plate, and the threaded rod can slide and rotate along the inner wall of the through hole of the outer shell.

[0005] Preferably, the pressure mechanism includes: The torsion assembly is fixedly mounted at the end of the threaded rod away from the limit rod. The snap-fit ​​assembly is slidably mounted on the outer wall of the slide bar. When the torsion assembly drives the threaded rod to rotate, the threaded rod will drive the snap-fit ​​assembly to slide along the outer wall of the slide rod and clamp the outer wall of the fuse tube, thus completing the installation process.

[0006] Preferably, the fixing mechanism includes: A sliding component is fixedly mounted on the side wall of the sliding plate; A tensioning component is fixedly installed on the side wall of the housing; After the latching assembly contacts the fuse tube, the operator can continue to twist the assembly. As the latching assembly continues to rotate, the sliding plate will move along the inner cavity of the housing towards the limiting rod.

[0007] Preferably, the limiting mechanism includes: A rotating assembly is fixedly mounted on the inner wall of the outer shell cavity. A positioning component is fixedly installed on the outer wall of the rotating component; When the sliding plate moves the sliding assembly, the rotating assembly will rotate and force the end of the positioning assembly to press against the outer wall of the slide rod.

[0008] Preferably, the torsion assembly includes a torsion block fixedly connected to the end of the threaded rod away from the limit rod; During installation, workers need to twist the screw block to rotate the threaded rod, so that the outer wall of the limit rod fits against the inner wall of the threaded rod's cavity.

[0009] Preferably, the snap-fit ​​assembly includes a threaded block slidably connected to the outer wall of the slide bar, and an arc-shaped clamping plate is fixedly connected to the side wall of the threaded block; The inner wall of the threaded block is threadedly connected to the outer wall of the threaded rod. When the threaded rod rotates, it will drive the threaded block to move along the outer wall of the slide rod.

[0010] Preferably, the sliding assembly includes a positioning rod fixedly connected to the outer wall of the sliding plate, and a groove is provided on the side wall of the threaded rod; The end of the spring away from the sliding plate is fixedly connected to the inner wall of the cavity of the outer shell. Under normal conditions, the spring is in an extended state. When the sliding plate moves towards the limiting rod, the spring will be compressed and deformed, accumulating potential energy.

[0011] Preferably, the pulling assembly includes a sliding tube fixedly connected to the side wall of the housing, a sliding rod slidably connected to the inner wall of the sliding tube, and a toggle plate fixedly connected to the side wall of the sliding rod; A protruding block is fixedly connected to the end of the sliding rod away from the dial.

[0012] Preferably, the rotating assembly includes a fixed column fixedly connected to the inner wall of the outer shell cavity, and a rotating ring rotatably connected to the outer wall of the fixed column; The rotating ring has a slot on its side wall, and the positioning rod passes through the slot of the rotating ring. When the sliding plate moves back and forth, the positioning rod drives the rotating ring to rotate around the fixed column.

[0013] Preferably, the positioning component includes a spring sheet fixedly connected to the outer wall of the rotating ring, and a protruding block is fixedly connected to the end of the spring sheet away from the rotating ring; When the sliding plate moves, the rotating ring will rotate counterclockwise and cause the protruding block to contact the outer wall of the threaded rod. During this process, the spring sheet will be compressed and deformed, accumulating potential energy.

[0014] The present invention has the following beneficial effects: (1) This invention addresses the problem of equipment loosening under high-frequency vibration. It includes a fixing mechanism and a limiting mechanism inside the equipment. When the threaded rod is twisted, it moves along the inner wall of the threaded block towards the limiting rod. Simultaneously, the threaded rod drives the sliding plate to move in the same direction via the fixing ring. The sliding plate, through the positioning rod, forces the rotating ring and spring plate to rotate counterclockwise around the fixing column, causing the end of the spring plate to contact the outer wall of the threaded rod and deform. Figure 7 The state changes to Figure 9 In this state, the protruding block will be tightly attached to the outer wall of the threaded rod. As the threaded rod continues to move towards the limiting rod, the protruding block will be stuck in the inner wall of the groove, restricting the rotation of the threaded rod. Through the above design, after the equipment is installed, the positioning component will restrict the rotation of the threaded rod, preventing the threaded rod from rotating due to external high-frequency vibration, which would cause a decrease in the clamping force of the equipment.

[0015] (2) The present invention utilizes the above-mentioned sliding plate sliding design and a spring is provided inside the device. When the sliding plate moves towards the limiting rod, the spring will be compressed and deformed, and accumulate potential energy, continuously forcing the sliding plate, the fixing ring and the threaded rod away from the limiting rod. This thrust will directly increase the friction between the threaded block and the threaded rod. Through the above design, when the threaded rod rotates slightly due to high-frequency vibration, the friction between the threaded block and the threaded rod can still provide sufficient clamping force for the device, preventing the phenomenon of separation due to loosening.

[0016] (3) In view of the above problems, the present invention utilizes the above-mentioned spring compression to improve the clamping force between the threaded block and the threaded rod. After the arc-shaped clamping plate just contacts the fuse tube, since the arc-shaped clamping plate can no longer move laterally, the threaded rod rotates at this time. The compression of the spring will increase the frictional resistance between the threaded rod and the threaded block. As the threaded rod continues to move laterally, the pressure released by the spring will be greater. By replacing the conventional rigid clamping design with the above-mentioned flexible clamping, the probability of fuse tube breakage is reduced during installation. At the same time, when the operator twists the screw block, if the equipment makes a "click" sound, it means that the equipment is in the best clamping state, thus improving the installation efficiency of the equipment.

[0017] (4) The present invention adopts a protruding block to restrict the rotation of the threaded rod. Compared with the conventional design of clamping the threaded rod with other screws, the fixing mechanism and the limiting mechanism of the present invention will be located on the inner wall of the shell, which effectively reduces the rusting speed. With the design of clamping the threaded rod with other screws, the screws will rust after long-term use, and the rusted nuts will affect the efficiency of later equipment maintenance and battery replacement.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1 - Figure 7 This invention relates to an intelligent detection device for outdoor fuses, comprising a detector 13, an arc-shaped plate 14 rotatably connected to the side wall of the detector 13, and a fastener 15 fixedly connected to the side wall of the arc-shaped plate 14, and further comprising: Pressure mechanism 1 is fixedly installed on the top of the detector 13. Pressure mechanism 1 includes a housing 111 fixedly connected to the top of the detector 13. A threaded rod 112 is slidably connected to the inner wall of the through hole of the housing 111. A limit rod 114 is fixedly connected to the inner wall of the housing 111. A slide rod 121 is fixedly connected to the inner wall of the housing 111. The fixing mechanism 2 is slidably disposed on the inner wall of the cavity of the outer shell 111. The fixing mechanism 2 includes a sliding plate 212 slidably connected to the inner wall of the cavity of the outer shell 111, a fixing ring 211 fixedly connected to the outer wall of the threaded rod 112, and a spring 215 fixedly connected to the side wall of the sliding plate 212. The limiting mechanism 3 is fixedly installed on the inner wall of the cavity of the outer shell 111; The outer wall of the fixing ring 211 is rotatably connected to the inner wall of the groove of the sliding plate 212, and the threaded rod 112 can slide and rotate along the inner wall of the through hole of the outer shell 111.

[0023] Pressure mechanism 1 includes: Torsion assembly 11 is fixedly disposed at the end of threaded rod 112 away from limit rod 114; The snap-fit ​​assembly 12 is slidably disposed on the outer wall of the slide rod 121; When the twisting component 11 drives the threaded rod 112 to rotate, the threaded rod 112 will drive the snap-fit ​​component 12 to slide along the outer wall of the slide rod 121 and clamp the outer wall of the fuse tube to complete the installation process.

[0024] Fixed mechanism 2 includes: Sliding component 21 is fixedly disposed on the side wall of sliding plate 212; Pulling component 22 is fixedly installed on the side wall of the outer casing 111; After the latching assembly 12 contacts the fuse tube, the operator can continue to twist the assembly 11. As the latching assembly 12 continues to rotate, the sliding plate 212 will move along the inner cavity of the outer shell 111 toward the limiting rod 114.

[0025] Restricted agency 3 includes: Rotating assembly 31 is fixedly mounted on the inner wall of the cavity of the outer shell 111; Positioning component 32 is fixedly installed on the outer wall of rotating component 31; When the sliding plate 212 drives the sliding assembly 21 to move, the rotating assembly 31 will rotate and force the end of the positioning assembly 32 to press against the outer wall of the slide rod 121.

[0026] Example 2, please refer to Figure 2 - Figure 9 The present invention is an intelligent detection device for outdoor fuses. Based on the first embodiment, the twisting component 11 includes a twisting block 113 fixedly connected to the end of the threaded rod 112 away from the limiting rod 114. To address the issue of equipment loosening under high-frequency vibration, a fixing mechanism 2 and a limiting mechanism 3 are installed inside the equipment. During the installation process, there are two processes: First, when the screwing block 113 drives the threaded block 122 to slide through the threaded rod 112, the arc-shaped clamping plate 123 first contacts the outer wall of the fuse tube, and the arc-shaped clamping plate 123 forms a clamp with the inner wall of the outer shell 111.

[0027] The buckle assembly 12 includes a threaded block 122 that is slidably connected to the outer wall of the slide rod 121, and an arc-shaped clamping plate 123 is fixedly connected to the side wall of the threaded block 122. Before use, first open the buckle 15 to allow the arc plate 14 to open outwards; place the device on the outer wall of the fuse tube, and fasten the buckle 15 so that the detector 13 and the arc plate 14 initially clamp the fuse tube. Then rotate the torsion assembly 11 to drive the threaded rod 112 to rotate, causing the buckle assembly 12 to slide along the outer wall of the slide rod 121, so that the inner wall of the arc clamping plate 123 fits against the outer wall of the fuse tube; continue to rotate the torsion block 113 until a "click" sound is heard, indicating that the installation is complete.

[0028] The sliding assembly 21 includes a positioning rod 213 fixedly connected to the outer wall of the sliding plate 212, and a groove 214 is provided on the side wall of the threaded rod 112; Utilizing the sliding design of the sliding plate 212, a spring 215 is installed inside the device. When the sliding plate 212 moves towards the limiting rod 114, the spring 215 will be compressed and deformed, accumulating potential energy. This continuously forces the sliding plate 212, the fixing ring 211, and the threaded rod 112 away from the limiting rod 114. This thrust directly increases the friction between the threaded block 122 and the threaded rod 112. Through this design, even when the threaded rod 112 rotates slightly due to high-frequency vibration, the friction between the threaded block 122 and the threaded rod 112 can still provide sufficient clamping force for the device, preventing detachment due to loosening.

[0029] The pulling assembly 22 includes a sliding tube 221 fixedly connected to the side wall of the housing 111, a sliding rod 222 slidably connected to the inner wall of the sliding tube 221, and a toggle disc 223 fixedly connected to the side wall of the sliding rod 222. To address the above issues, the design utilizes the compression of spring 215 to increase the clamping force between threaded block 122 and threaded rod 112. After the arc-shaped clamping plate 123 just contacts the fuse tube, it can no longer move laterally. At this point, the threaded rod 112 rotates, and the compression of spring 215 increases the frictional resistance between the threaded rod 112 and threaded block 122. Furthermore, as the threaded rod 112 continues to move laterally, the pressure released by spring 215 increases. By replacing the conventional rigid clamping design with this flexible clamping, the probability of fuse tube breakage is reduced during installation. Additionally, if the equipment makes a "click" sound when the operator twists and turns block 113, it indicates that the equipment is in the optimal clamping state, improving installation efficiency.

[0030] The rotating assembly 31 includes a fixed column 311 fixedly connected to the inner wall of the cavity of the outer shell 111, and a rotating ring 312 rotatably connected to the outer wall of the fixed column 311; When maintenance personnel need to disassemble the equipment, they can pull the actuating disc 223, which forces the actuating disc 223 to drive the sliding rod 222 to move outward along the inner wall of the sliding tube 221. At this time, the protruding block at the end of the sliding rod 222 will force the spring plate 321 to bend, so that the protruding block 322 moves away from the groove 214, releasing the restriction of the protruding block 322 on the threaded rod 112. Then, the staff can rotate the screwing block 113 in the opposite direction to disassemble the equipment.

[0031] The positioning component 32 includes a spring plate 321 fixedly connected to the outer wall of the rotating ring 312, and a protrusion 322 fixedly connected to the end of the spring plate 321 away from the rotating ring 312; As the threaded rod 112 continues to rotate, since the arc-shaped clamping plate 123 has already made contact with the fuse tube and cannot move laterally again, the threaded rod 112 will move along the inner wall of the threaded block 122 towards the limiting rod 114 as the threaded rod 112 continues to twist. Simultaneously, the threaded rod 112 will drive the sliding plate 212 to move in the same direction via the fixing ring 211. The sliding plate 212, through the positioning rod 213, forces the rotating ring 312 and the spring plate 321 to rotate counterclockwise around the fixing post 311, causing the end of the spring plate 321 to contact the outer wall of the threaded rod 112 and deform. Figure 7 The state changes to Figure 9 In this state, the protruding block 322 will be tightly attached to the outer wall of the threaded rod 112. As the threaded rod 112 continues to move towards the limiting rod 114, the protruding block 322 will be locked in the inner wall of the groove 214, restricting the rotation of the threaded rod 112. Through the above design, after the equipment is installed, the positioning component 32 will restrict the rotation of the threaded rod 112, preventing the threaded rod 112 from rotating due to external high-frequency vibration, which would cause a decrease in the clamping force of the equipment.

[0032] One specific application of this embodiment is as follows: Before use, first open the buckle 15 to allow the arc plate 14 to open outwards; place the device on the outer wall of the fuse tube, and fasten the buckle 15 so that the detector 13 and the arc plate 14 initially clamp the fuse tube. Then rotate the torsion assembly 11 to drive the threaded rod 112 to rotate, causing the buckle assembly 12 to slide along the outer wall of the slide rod 121, so that the inner wall of the arc clamping plate 123 fits against the outer wall of the fuse tube; continue to rotate the twisting block 113 until a "click" sound is heard, which completes the installation.

[0033] To address the issue of equipment loosening under high-frequency vibration, a fixing mechanism 2 and a limiting mechanism 3 are installed inside the equipment. During equipment installation, the following two processes occur: First, when the screwing block 113 drives the threaded block 122 to slide via the threaded rod 112, the arc-shaped clamping plate 123 first contacts the outer wall of the fuse tube, forming a clamp with the inner wall of the outer casing 111; Second, as the threaded rod 112 continues to rotate, the arc-shaped clamping plate 123 has already made contact with the fuse tube, and the arc... The clamping plate 123 can no longer move laterally. With the threaded rod 112 continuing to twist, it will move along the inner wall of the threaded block 122 towards the limiting rod 114. Simultaneously, the threaded rod 112 will drive the sliding plate 212 to move in the same direction via the fixing ring 211. The sliding plate 212, through the positioning rod 213, forces the rotating ring 312 and the spring plate 321 to rotate counterclockwise around the fixing post 311, causing the end of the spring plate 321 to contact the outer wall of the threaded rod 112 and deform. Figure 7 The state changes to Figure 9 In this state, the protruding block 322 will be tightly attached to the outer wall of the threaded rod 112. As the threaded rod 112 continues to move towards the limiting rod 114, the protruding block 322 will be locked in the inner wall of the groove 214, restricting the rotation of the threaded rod 112. Through the above design, after the equipment is installed, the positioning component 32 will restrict the rotation of the threaded rod 112, preventing the threaded rod 112 from rotating due to external high-frequency vibration, which would cause a decrease in the clamping force of the equipment.

[0034] Utilizing the sliding design of the sliding plate 212, a spring 215 is installed inside the device. When the sliding plate 212 moves towards the limiting rod 114, the spring 215 will be compressed and deformed, accumulating potential energy. This continuously forces the sliding plate 212, the fixing ring 211, and the threaded rod 112 away from the limiting rod 114. This thrust directly increases the friction between the threaded block 122 and the threaded rod 112. Through this design, even when the threaded rod 112 rotates slightly due to high-frequency vibration, the friction between the threaded block 122 and the threaded rod 112 can still provide sufficient clamping force for the device, preventing detachment due to loosening.

[0035] Since the fuse tube is mostly made of ceramic material, when it is rigidly clamped, in order to ensure that the equipment can be stably installed on the outer wall of the fuse tube, the threaded rod 112 needs to be tightened forcefully. This pressure will be directly transmitted to the fuse tube. When the pressure is too high, the fuse tube will rupture. To address the above issues, the design utilizes the compression of spring 215 to increase the clamping force between threaded block 122 and threaded rod 112. After the arc-shaped clamping plate 123 just contacts the fuse tube, it can no longer move laterally. At this point, the threaded rod 112 rotates, and the compression of spring 215 increases the frictional resistance between the threaded rod 112 and threaded block 122. Furthermore, as the threaded rod 112 continues to move laterally, the pressure released by spring 215 increases. By replacing the conventional rigid clamping design with this flexible clamping, the probability of fuse tube breakage is reduced during installation. Additionally, if the equipment makes a "click" sound when the operator twists and turns block 113, it indicates that the equipment is in the optimal clamping state, improving installation efficiency.

[0036] The design of using protruding block 322 to restrict the rotation of threaded rod 112 is different from the conventional design of clamping threaded rod 112 with other screws. The fixing mechanism 2 and the limiting mechanism 3 of the present invention are located on the inner wall of the outer shell 111, which effectively reduces the rate of rusting. The design of clamping threaded rod 112 with other screws will cause the screws to rust after long-term use, and the rusted nuts will affect the efficiency of later equipment maintenance and battery replacement.

[0037] When maintenance personnel need to disassemble the equipment, they can pull the actuating disc 223, which forces the actuating disc 223 to drive the sliding rod 222 to move outward along the inner wall of the sliding tube 221. At this time, the protruding block at the end of the sliding rod 222 will force the spring plate 321 to bend, so that the protruding block 322 moves away from the groove 214, releasing the restriction of the protruding block 322 on the threaded rod 112. Then, the staff can rotate the screwing block 113 in the opposite direction to disassemble the equipment.
