Description

Technical Field

[0001] The present invention relates to the technical field of power grid fault detection and early warning, and specifically to an intelligent power grid fault detection and early warning device based on artificial intelligence. Background Art

[0002] The smart grid is the intelligence of the power grid, also known as "Power Grid 2.0". It is based on an integrated, high-speed two-way communication network. Through the application of advanced sensing and measurement technologies, advanced equipment technologies, advanced control methods, and advanced decision support system technologies, it realizes the goals of reliable, safe, economic, efficient, environmentally friendly, and user-safe operation of the power grid. Its main features include self-healing, motivating and protecting users, resisting attacks, providing power quality that meets user needs, allowing access to various different power generation forms, initiating the power market, and optimizing the efficient operation of assets. During the operation of the smart grid, it is necessary to detect its operating status in real time. Since temperature directly affects the operation of power grid equipment, when detecting power grid faults, the temperature of the power grid lines is usually detected in real time.

[0003] During the process of detecting the temperature of power grid lines, if unexpected situations occur, such as the temperature of the power grid lines rising sharply, causing damage to the internal equipment between the power grids due to the high temperature of the lines, the existing intelligent power grid fault intelligent detection devices do not have emergency measures and can only give a pre-alarm to remind the staff to take safety measures. However, during the period from the alarm to the staff taking safety measures, the temperature between the power grid lines may rise to an uncontrollable level, resulting in irreversible damage to the lines, reducing the safety and protection of the power grid fault detection device. In response to this, this design proposes an intelligent power grid fault detection and early warning device based on artificial intelligence. Summary of the Invention

[0007] The circuit detection component includes a back plate, a solar panel, and a support frame. The back plate is installed on the back of the detection box. The solar panel is installed on the outside of the back plate. The support frame is installed at the upper edge of the inner wall of the back plate. A plurality of connecting grooves are equidistantly formed at the top of the support frame. Temperature sensors are installed on both sides of the inner wall of each connecting groove.

[0008] In one example, a spring is fixedly provided on one side of the inner wall of each first limiting chute, and one end of each spring is fixedly connected to one side of the slider.

[0009] In one example, second limiting chutes are formed at the outer edges of the other two sides of each mounting groove at the top of the mounting frame. The bottom of each metal snap ring is slidably connected to the inner wall of each second limiting chute. Through grooves are formed at the bottom of the inner wall of each second limiting chute. A metal strip is fixedly provided at the bottom of each metal snap ring.

[0010] In one example, a storage groove is formed on one side of the top of the mounting frame. A small motor is installed on the inner wall of each storage groove. One end of each limiting frame passes through the inner wall of each storage groove and is fixedly connected to the output end of each small motor.

[0011] In one example, a plurality of metal card slots are fixedly provided at equal intervals at the bottom of the mounting frame. A fixing bolt is threadedly connected to one side of each metal card slot. One end of each metal strip passes through the inner wall of each through groove and contacts the top of the metal card slot.

[0012] In one example, a baffle is installed at the edge of one side of the inner wall of the detection groove. Fixing blocks are installed at the four corners of one side of the inner wall of the detection groove. Screws are inserted through the four corners of the baffle, and the outer walls of one ends of the four screws are threadedly connected to the inner walls of the four fixing blocks.

[0013] In one example, a plurality of first power grid wires are inserted and connected at equal distances at the bottom of the detection box. A plurality of protective rubber sleeves are installed at equal distances at the top of the detection box.

Among them, the second power grid wire is connected through the mounting frame, and under the temperature detection of the temperature sensor in the detection component, if a fault occurs and the temperature rises, the small motor will start to rotate the limit frame immediately, so that the convex block pushes the connecting rod to extend under the sliding of the slider, and drives the metal snap ring to slide in the second limit chute to move away from and no longer contact the second power grid wire, cutting off the power. At the same time, when the metal snap ring moves, it contacts the contact block to make the alarm energized and alarm. The staff can immediately find the faulty line according to the position of the corresponding alarm, improving the safety and protection of the detection device when detecting power grid lines.

[0018] 2.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7 , the present invention provides a technical solution: an intelligent detection and early warning device for power grid faults based on artificial intelligence, including a power grid detection box 1, a detection tank 2, and a power-off alarm mechanism 3, a circuit detection component 4, and a line carding mechanism 11 all installed inside the detection tank 2. The detection tank 2 is opened inside the power grid detection box 1;

[0029] The power-off alarm mechanism 3 includes a mounting bracket 301 installed at the lower edge of the inner wall of the detection groove 2. A plurality of mounting grooves 302 are equidistantly formed at the top of the mounting bracket 301. A limiting bracket 303 is rotatably connected to the outer edge of each mounting groove 302 at the top of the mounting bracket 301. A convex block 304 is fixedly provided on one side of each limiting bracket 303. A plurality of alarms 305 are equidistantly installed on one side of the outer wall of the mounting bracket 301. A plurality of contact blocks 306 are equidistantly installed at the top of the mounting bracket 301. A first wire 307 is inserted and connected to one side of each alarm 305, and one end of each first wire 307 is fixedly connected to one side of each contact block 306. A first limiting chute 308 is formed at the outer edge of each mounting groove 302 at the top of the mounting bracket 301. A slider 309 is slidably connected to the inner wall of each first limiting chute 308. A connecting rod 310 is rotatably connected to the top of each slider 309. Metal snap rings 311 are rotatably connected to both ends of each connecting rod 310;

[0030] The circuit detection component 4 includes a back plate 401, a solar panel 402, and a support frame 403. The back plate 401 is installed on the back of the detection box 1. The solar panel 402 is installed on the outside of the back plate 401. The support frame 403 is installed at the upper edge of the inner wall of the back plate 401. A plurality of connection grooves 404 are equidistantly formed at the top of the support frame 403. Temperature sensors 405 are installed on both sides of the inner wall of each connection groove 404;

[0031] During use, the first power grid wire 7 and the second power grid wire 10 are respectively connected through the top and bottom of the detection box 1, implementing a segmented connection. When connecting, the first power grid wire 7 is fixedly connected to the metal card slot 317 at the bottom of the mounting frame 301 by passing through the bottom of the detection box 1. The second power grid wire 10 is inserted and connected to the mounting slot 302 at the top of the mounting frame 301 by passing through the inner wall of the detection slot 2, and is clamped and fixed by two metal snap rings 311 outside the mounting slot 302. Since the mounting frame 301 is made of insulating material, while the two metal snap rings 311 on both sides are made of conductive metal material, and the metal snap rings 311 are in contact with the metal card slot 317 at the bottom of the mounting frame 301 through the metal connecting strip 315 at the bottom passing through the through slot 314, thereby electrically connecting the first power grid wire 7 and the second power grid wire 10 connected up and down the detection box 1. And the first power grid wire 7 is connected to the main power supply. After connecting the circuit equipment, the normal current can flow through and operate. And the second power grid wire 10 above passes through the detection component 4 and is detected in real time. The second power grid wire 10 passes through the inner wall of the connection slot 404 at the top of the support frame 403, and the temperature sensors 405 on both sides of the inner wall of the connection slot 404 monitor the temperature on its surface in real time. Once a fault occurs in the power grid equipment, the current and resistance on the line will change. After the line is overloaded, the temperature at its upper end will rise rapidly. After exceeding the installation and detection range of the temperature sensor 405, it will issue an instruction to control the small motor 316 to drive the rotation limiting frame 303. When the limiting frame 303 rotates, the convex block 304 on one side of it will squeeze the outer wall of the connecting rod 310, causing it to slide in the first limiting chute 308 by the slider 309 and compress the spring 312. Then the two ends of the connecting rod 310 will drive the two metal snap rings 311 on both sides to slide in the second limiting chute 313 and move away from the second power grid wire 10, so that the electrical connection between the second power grid wire 10 and the first power grid wire 7 is lost, and the power grid line is powered off. At the same time, one of the metal snap rings 311 slides in the second limiting chute 313 until it contacts the contact block 306. The metal snap ring 311 electrically connects the contact block 306 to the metal card slot 317 below through the metal connecting strip 315, and then electrically connects to the power grid wire 7 below, so that the alarm 305 is powered on and emits an alarm. And a separate alarm 305 is provided between each first power grid wire 7 and the second power grid wire 10. Therefore, after the alarm 305 alarms, the staff can open the detection box 1 to find out which line has a fault in the first time and carry out maintenance in the first time, improving the safety and protection of the device when detecting the power grid line;

[0032] Further, on one side of the inner wall of each first limit chute 308, a spring 312 is fixedly provided, and one end of each spring 312 is fixedly connected to one side of the slider 309. When the limit frame 303 rotates, the convex block 304 squeezes the connecting rod 310 to extend, and the slider 309 slides in the first limit chute 308 to compress the spring 312. When there is no circuit fault, the convex block 304 does not contact the connecting rod 310, and the slider 309 returns to its original position under the elastic action of the spring 312, so that the position of the connecting rod 310 does not affect the contact between the metal snap ring 311 and the outer wall of the circuit.

[0033] Further, on the outer edges of the other two sides of each installation groove 302 at the top of the mounting frame 301, second limit chutes 313 are respectively provided, and the bottom of each metal snap ring 311 is slidably connected to the inner wall of each second limit chute 313. At the bottom of the inner wall of each second limit chute 313, through grooves 314 are respectively provided. At the bottom of each metal snap ring 311, a metal connecting strip 315 is fixedly provided. The first power grid wire 7 contacts the metal connecting strip 315 through the metal card slot 317, and thus is electrically connected to the metal snap ring 311. The metal snap ring 311 contacts the second power grid wire 10, so that the first power grid wire is electrically connected to the second power grid wire 10.

[0034] On one side of the top of the mounting frame 301, storage grooves are respectively provided. On the inner wall of each storage groove, a small motor 316 is installed, and one end of each limit frame 303 respectively passes through the inner wall of each storage groove and is fixedly connected to the output end of each small motor 316. When the small motor 316 is driven, the limit frame 303 rotates, and the rotational force is sufficient for the convex block 304 on the limit frame 303 to push the connecting rod 310 to extend.

[0035] Further, a plurality of metal card slots 317 are fixedly provided at equal intervals at the bottom of the mounting frame 301. On one side of each metal card slot 317, a fixing bolt 318 is threadedly connected. One end of each metal connecting strip 315 respectively passes through the inner wall of each through groove 314 and contacts the top of the metal card slot 317. After the first power grid wire 7 is clamped into the metal card slot 317, the fixing bolt 318 is tightened to pass through the inner wall of the metal card slot 317 to squeeze and fix it.

[0036] Further, a baffle 5 is installed at the edge of one side of the inner wall of the detection groove 2, and fixing blocks 6 are installed at the four corners of one side of the inner wall of the detection groove 2. Screws are respectively inserted through the four corners of the baffle 5, and the outer walls of one ends of the four screws are respectively threadedly connected to the inner walls of the four fixing blocks 6. During the use of the detection device, the baffle 5 is fixed to the fixing block 6 by screws to close the detection groove 2.

[0037] Furthermore, a plurality of first power lines 7 are equidistantly inserted and connected at the bottom of the detection box 1, a plurality of protective rubber sleeves 8 are equidistantly installed at the top of the detection box 1, and one end of each first power line 7 passes through the bottom of the detection box 1 and is inserted and connected with the inner wall of each metal slot 317, and is tightened and fixed inside each metal slot 317 by each fixing bolt 318, a plurality of second wires 9 are equidistantly inserted and connected at the top of the mounting frame 301, and each small motor 316 and each temperature sensor 405 are electrically connected to the solar panel 402 through each second wire 9. The inner wall of each installation groove 302 is interlaced with a second power grid line 10, and the temperature sensor 405 on the detection component 4 is powered by the solar panel 402, so that it can sense and detect the temperature on the second power grid line 10 in real time, and the small motor 316 is also electrically connected to the solar panel 402 through the second wire 9. When the temperature sensor 405 is not triggered, no current flows on the second wire 9. Once the temperature sensor 405 is triggered, the current switch is turned on, and the small motor 316 is powered to drive the rotation limit frame 303 to rotate;

[0038] Furthermore, the combing mechanism 11 includes a line combing frame 1101 installed in the middle position of the inner wall of the detection slot 2, and a plurality of first connection holes 1102 are equidistantly provided on the top of each line combing frame 1101, and a second connection hole 1103 is provided on the top of the line combing frame 1101 at the outer edge of each first connection hole 1102. The second power grid line 10 and the second conductor 9 connected to the inside of the detection slot 2 are combed and interspersed through the first connection hole 1102 and the second connection hole 1103 at the upper end of the combing mechanism 11, respectively, so that the inside of the detection slot 2 is kept tidy, so that when a fault occurs later, the staff can quickly locate the faulty line.

[0039] The outer wall of one end of each second power grid line 10 passes through the inner wall of each first connecting hole 1102 and the inner wall of each connecting groove 404, and is connected to the inner wall of each protective rubber sleeve 8. The outer wall of each second conducting wire 9 is connected to the inner wall of each second connecting hole 1103, and when the second power grid line 10 is inserted in the detection groove 2, one end thereof is inserted through the protective rubber sleeve 8, and the second power grid line 10 is inserted in the protective rubber sleeve 8 and squeezed by the inner wall of the protective rubber sleeve 8, so that the end thereof entering the inside of the detection groove 2 cannot be pulled out at will, and therefore, it will not easily detach from the installation groove 302. In case of a fault later, the second power grid line 10 corresponding to the fault can be pulled out forcefully.
