Description

Technical Field

[0001] This invention relates to the field of intelligent monitoring technology, and in particular to an intelligent monitoring system for intelligent mining circuit breakers. Background Technology

[0002] Mining circuit breakers are key equipment in coal mine power supply systems, primarily used to ensure the safe operation of underground power systems. A mining circuit breaker is a switching device capable of closing, carrying, and interrupting normal circuit currents, and carrying and interrupting abnormal circuit currents (such as short circuits and overloads) within a specified time. Its core value lies in quickly cutting off fault currents and preventing accidents from escalating.

[0003] Mine power supply faces challenging working conditions such as humidity, dust, confined spaces, and complex electromagnetic interference. With the continuous development of smart mines and green transformation in my country, traditional mine power supply systems are struggling to meet reliability, safety, and intelligent requirements. There is an urgent need to develop highly reliable solid-insulated primary equipment suitable for harsh mine working conditions and to develop secondary monitoring and protection units capable of accurately identifying early-stage faults.

[0004] Currently, there is a lack of intelligent monitoring systems that can monitor the location of circuit breakers and the temperature of busbars, enabling early fault detection. Once the equipment is applied, it can effectively detect early faults, reduce the risk of leakage and short circuits, and greatly improve the safety and reliability of underground power supply in coal mines. This has important practical significance and value for building safe, efficient, green, and energy-efficient modern mines.

[0005] Therefore, in order to address the above problems, an intelligent monitoring system for intelligent mining circuit breakers is proposed. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention develops an intelligent monitoring system for intelligent mining circuit breakers. This invention enables the monitoring of the circuit breaker's location and busbar temperature, achieving early fault detection.

[0007] The technical solution to the technical problem solved by this invention is as follows: This invention provides an intelligent monitoring system for intelligent mining circuit breakers, comprising: an explosion-proof enclosure, a connecting partition, the partition having six evenly distributed wire-passing holes, the explosion-proof enclosure being connected to a base, the base being connected to symmetrical convex groove tracks, the base having symmetrical inner guide rods connected inside, and the upper part of the base having a slot; a circuit breaker, a connecting mounting base, the mounting base having a monitoring hole, the mounting base being connected to symmetrical convex tracks, the symmetrical convex tracks matching the symmetrical convex groove tracks, and when installing the circuit breaker, inserting the convex tracks into the convex groove tracks, pushing the circuit breaker to the installation position, and then installing the circuit breaker with bolts. The circuit breaker is matched with a set of busbars, which are connected to busbar seats. The busbar seats are connected to the partition plate, and the busbars are matched with the through-holes. A position monitoring assembly includes a horizontal plate, symmetrical inner guide rods passing through one end of the horizontal plate, a symmetrical vertical plate connected to the horizontal plate, and the symmetrical vertical plates rotatably connected to a T-axis. The T-axis is connected to a vertical cylinder, and a first pressure sensor is connected inside the vertical cylinder. The first pressure sensor is connected to a vertical insertion rod via a first spring. The first spring and the lower part of the insertion rod are located inside the vertical cylinder, and the insertion rod matches the monitoring hole. After the circuit breaker is installed, the vertical insertion rod is inserted vertically into the monitoring hole, causing the vertical insertion rod to compress the first spring, which in turn causes the first pressure sensor to measure the pressure value. When the bolts loosen and the circuit breaker moves along the height direction, the first spring recovers, and the pressure value measured by the first pressure sensor changes.

[0008] As an optimization, the horizontal plate connects to a U-plate, which in turn connects to symmetrical second pressure sensors and square tubes. The symmetrical second pressure sensors are each connected to a square rod via a second spring. One end of each symmetrical second spring and symmetrical square rod is positioned within a corresponding square tube. The symmetrical square rods are connected to blocks, which in turn connect to symmetrical circular blocks. The T-axis connects to symmetrical sliding grooves, and the symmetrical circular blocks are positioned within their respective sliding grooves. The inner diameter of the monitoring hole is larger than the diameter of the vertical insertion rod. When the circuit breaker moves along the groove track, because the inner diameter of the monitoring hole is larger than the diameter of the vertical insertion rod, the mounting base contacts the vertical insertion rod at the edge of the monitoring hole, causing the vertical insertion rod to swing and tilt. When the upper part of the vertical insertion rod also contacts the sidewall of the monitoring hole corresponding to the mounting base, it reaches its limit position. As the circuit breaker continues to move, the vertical insertion rod deforms. When the vertical insertion rod swings, the square rod compresses one side of the second spring and stretches the other side of the second spring, causing a change in the pressure value measured by the corresponding second pressure sensor, thus enabling monitoring of the circuit breaker's movement along the groove track. In the initial state, both second springs are compressed, and the side with the smaller pressure value measured by the second pressure sensor is the direction in which the circuit breaker moves.

[0009] As an optimization, a power assembly is also included. This power assembly comprises a crankshaft, which is connected to the housing bearing. The cross plate has a straight groove, and the middle curved portion of the crankshaft is located within this groove. By employing the power assembly, the crankshaft rotation drives the position monitoring assembly to move along the height direction. Before circuit breaker installation, the middle curved portion is at its lowest point of travel. This facilitates circuit breaker installation. After installation, rotating the crankshaft allows the vertical insertion rod to be inserted vertically into the monitoring hole, facilitating monitoring.

[0010] As an optimization, an auxiliary installation component is also included. This component comprises symmetrical mounting slots, each bearing a set of auxiliary wheels. The symmetrical mounting slots are also connected to connecting plates, each with a straight edge groove. The curved portions at both ends of the crankshaft are respectively positioned within the corresponding straight edge grooves. Two sets of symmetrical external guide rods are connected within the housing, each guide rod passing through one end of a corresponding mounting slot. The housing has elongated through-grooves corresponding to the two sets of auxiliary wheels. Before circuit breaker installation, the upper ends of the auxiliary wheels are higher than the housing. Installing the circuit breaker allows the convex track to contact the auxiliary wheels, moving them along the convex groove track for easier circuit breaker installation.

[0011] As an optimization, the crankshaft is connected to a turntable, and a positioning bolt is connected to the edge of the turntable. The housing is provided with two positioning holes, and the positioning bolt matches the positioning holes. By using positioning bolts and positioning holes, the position of the crankshaft can be easily locked, facilitating the installation and monitoring of the circuit breaker.

[0012] As an optimization, a set of busbar monitoring components is also included. The busbar monitoring components include fixed rings. The partition is connected to the corresponding fixed ring for each of the wire holes. The fixed rings are connected to three evenly distributed T-frames. Each T-frame is connected to an inclined U-frame. Each inclined U-frame is provided with a rear inclined groove and a front inclined groove. Each T-frame is provided with a radial guide rod. Each radial guide rod is connected to a frame. Each frame is provided with two cross grooves. Each cross groove is provided with a movable U-frame. The middle of the crossbar of each movable U-frame is a round shaft. Each round shaft on the front side is provided in the corresponding front inclined groove. Each round shaft on the rear side is provided in the corresponding rear inclined groove. Each movable U-frame on the front side is connected to a spring damper through a mounting block. Each frame is connected to an integrated sensor. Each movable U-frame on the rear side is connected to an elliptical clamp. The integrated sensors include at least temperature and pressure sensors to measure the busbar's temperature and deformation, enabling timely monitoring of its condition, early fault detection, reduced leakage and short-circuit risks, and significantly improved safety and reliability of power supply in underground coal mines. The elliptical clamping plate moves inward and backward to hold the busbar, preventing it from bending and contacting the busbar seat under gravity during long-term use, thus avoiding damage to the busbar's outer sheath. The spring damper moves inward and forward, compressing the busbar seat to help maintain its position. A pressure sensor can be installed within the spring damper; when the busbar seat loosens and moves backward, the pressure value changes, allowing for position monitoring of the busbar seat.

[0013] As an optimization, the fixed ring is rotatably connected to the rotating ring, which is provided with a set of power inclined slots. Each power inclined slot contains a power rod, and each power rod is connected to a corresponding frame. By placing the power rods in the power inclined slots, the rotating ring rotates, driving the power rods to move, thereby achieving synchronous movement of a set of elliptical clamps, integrated sensors, and spring dampers.

[0014] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:

[0015] 1. This device uses a position monitoring component to monitor the position of the circuit breaker. After the circuit breaker is installed, the vertical insertion rod is inserted vertically into the monitoring hole, causing the rod to compress the first spring, which in turn causes the first pressure sensor to measure the pressure value. When the bolts loosen, as the circuit breaker moves along its height, the first spring returns to its original position, and the pressure value measured by the first pressure sensor changes. When the circuit breaker moves along the groove track, because the inner diameter of the monitoring hole is larger than the diameter of the vertical insertion rod, the mounting base contacts the vertical insertion rod at the edge of the monitoring hole, causing the rod to swing and tilt. The square rod compresses the second spring on one side and stretches the second spring on the other side, causing the pressure value measured by the corresponding second pressure sensor to change, thus enabling monitoring of the circuit breaker's movement along the groove track.

[0016] 2. This device employs a busbar monitoring component to monitor and support the busbar. Integrated sensors measure the busbar's temperature and deformation, allowing for timely monitoring of its condition and early fault detection. An elliptical clamping plate moves inward and backward to hold the busbar in place, preventing it from bending and contacting the busbar seat under gravity during prolonged use, thus avoiding damage to the busbar's outer sheath. A spring damper moves inward and forward to compress the busbar seat, assisting in maintaining its position. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] like Figures 1 to 10As shown in Embodiment 1: An intelligent monitoring system for intelligent mining circuit breakers includes: an explosion-proof enclosure 1, a connecting partition 11, the partition 11 having six evenly distributed wire-passing holes 12, the explosion-proof enclosure 1 being connected to a base 14, the base 14 being connected to symmetrical grooved tracks 13, the base 14 having symmetrical inner guide rods 18 connected inside, and the upper part of the base 14 having a slot 15; a circuit breaker 3, connected to a mounting base 31, the mounting base 31 having a monitoring hole 33, the mounting base 31 being connected to symmetrical convex tracks 32, the symmetrical convex tracks 32 matching the symmetrical grooved tracks 13, when installing the circuit breaker 3, the convex tracks 32 are inserted into the grooved tracks 13, pushing the circuit breaker 3 to the installation position, and the circuit breaker 3 is installed using bolts. The circuit breaker 3 is matched with a set of busbars 35, which are connected to busbar seats 34. The busbar seats 34 are connected to the partition plate 11, and the busbars 35 are matched with the through holes 12. The position monitoring component 5 includes a horizontal plate 510, with symmetrical inner guide rods 18 passing through one end of the horizontal plate 510. The horizontal plate 510 is connected to symmetrical vertical plates 512, which are rotatably connected to T-shafts 55. The T-shafts 55 are connected to a vertical cylinder 54, and a first pressure sensor 53 is connected inside the vertical cylinder 54. The first pressure sensor 53 is connected to a vertical insertion rod 51 via a first spring 52. The lower part of the first spring 52 and the insertion rod 51 are located inside the vertical cylinder 54, and the insertion rod 51 matches the monitoring hole 33. After the circuit breaker 3 is installed, the vertical insertion rod 51 is vertically inserted into the monitoring hole 33, causing the vertical insertion rod 51 to compress the first spring 52, thereby causing the first pressure sensor 53 to measure the pressure value. When the bolts loosen, the circuit breaker 3 moves along the height direction, the first spring 52 returns to its original state, and the pressure value measured by the first pressure sensor 53 changes.

[0037] The horizontal plate 510 is connected to the U-plate 56, which in turn connects to symmetrical second pressure sensors 57 and square tubes 59. The symmetrical second pressure sensors 57 are each connected to a square rod 514 via a second spring 58. One end of each of the symmetrical second spring 58 and the symmetrical square rod 514 is respectively positioned within the corresponding square tube 59. The symmetrical square rods 514 are each connected to a block 513, which in turn connects to symmetrical circular blocks 515. The T-axis 55 is connected to symmetrical sliding grooves 516, and the symmetrical circular blocks 515 are respectively positioned within their corresponding sliding grooves 516. The inner diameter of the monitoring hole 33 is larger than the diameter of the vertical insertion rod 51. When the circuit breaker 3 moves along the groove track 13, because the inner diameter of the monitoring hole 33 is larger than the diameter of the vertical rod 51, the mounting base 31 contacts the vertical rod 51 at the edge of the monitoring hole 33, causing the vertical rod 51 to swing and tilt. When the upper part of the vertical rod 51 also contacts the side wall of the monitoring hole 33 of the mounting base 31, it reaches its limit position. When the circuit breaker 3 continues to move, the vertical rod 51 deforms. When the vertical rod 51 swings, the square rod 514 compresses one side of the second spring 58 and stretches the other side of the second spring 58. The pressure value measured by the corresponding second pressure sensor 57 changes, realizing the monitoring of the movement of the circuit breaker 3 along the groove track 13. In the initial state, both sides of the second spring 58 are compressed. The side where the pressure value measured by the second pressure sensor 57 decreases is the direction of movement of the circuit breaker 3.

[0038] It also includes a power assembly 6, which includes a crankshaft 61. The housing 14 is bearing-connected to the crankshaft 61. The cross plate 510 is provided with a straight groove 511, and the middle curved portion 62 of the crankshaft 61 is disposed within the straight groove 511. By using the power assembly 6, when the crankshaft 61 rotates, it drives the position monitoring assembly 5 to move along the height direction. Before the circuit breaker 3 is installed, the middle curved portion 62 is at the lowest point of its stroke. This facilitates the installation of the circuit breaker 3. After installation, by rotating the crankshaft 61, the vertical insertion rod 51 is vertically inserted into the monitoring hole 33, facilitating monitoring.

[0039] The crankshaft 61 is connected to the turntable 64, and the edge of the turntable 64 is connected to the positioning bolt 65. The housing 14 is provided with two positioning holes 17, and the positioning bolt 65 matches the positioning holes 17. By using the positioning bolt 65 and the positioning holes 17, the position of the crankshaft 61 can be easily locked, which facilitates the installation and monitoring of the circuit breaker 3.

[0040] The workflow of this embodiment is as follows:

[0041] Before the circuit breaker 3 is installed, the middle bend 62 is at the lowest point of its travel.

[0042] Install circuit breaker 3, move the convex track 32 along the convex groove track 13, and install circuit breaker 3 with bolts. Unscrew the positioning bolt 65 from the positioning hole 17, rotate the turntable 64, the turntable 64 drives the crankshaft 61 to rotate, the crankshaft 61 drives the middle curved part 62 to swing in the middle straight groove 511, the middle curved part 62 drives the horizontal plate 510 to move along the inner guide rod 18, so that the vertical insertion rod 51 is inserted into the monitoring hole 33, so that the vertical insertion rod 51 compresses the first spring 52, so that the first pressure sensor 53 measures the pressure value, so that the positioning bolt 65 matches the other positioning hole 17, and tighten it into the other positioning hole 17.

[0043] When the bolts loosen, as the circuit breaker 3 moves along the height direction, the first spring 52 returns to its original position, and the pressure value measured by the first pressure sensor 53 changes. When the circuit breaker 3 moves along the groove track 13, the mounting base 31 contacts the vertical insertion rod 51, causing the vertical insertion rod 51 to swing. The vertical insertion rod 51 causes the first spring 52, the first pressure sensor 53, and the vertical cylinder 54 to swing. The vertical cylinder 54 causes the T-axis 55 to swing. The T-axis 55 causes the slide groove 516 to swing. The slide groove 516 causes the round block 515 to move. The round block 515 causes the square block 513 to move. The square block 513 causes the square rod 514 to move. The square rod 514 compresses one side of the second spring 58 and stretches the other side of the second spring 58. The pressure value measured by the corresponding second pressure sensor 57 changes, thus realizing the monitoring of the movement of the circuit breaker 3 along the groove track 13.

[0044] Example 2: This example further elaborates on Example 1, and also includes a busbar monitoring component 2. The busbar monitoring component 2 includes a fixing ring 25. The partition 11 is connected to the corresponding fixing ring 25 for each of the wire passage holes 12. The fixing ring 25 is connected to three evenly distributed T-frames 23. Each T-frame 23 is connected to a slanted U-frame 21. Each slanted U-frame 21 is provided with a rear slanted groove 22 and a front slanted groove 24. Each T-frame 23 is provided with a radial guide rod 210. Each radial guide rod 210 is connected to a frame 29. Each frame 29... Each frame 29 is provided with two cross slots 211, and each cross slot 211 is provided with a movable U-shaped frame 213. The middle part of the crossbar of each movable U-shaped frame 213 is a round shaft 212. Each round shaft 212 on the front side is respectively set in the corresponding front inclined slot 24, and each round shaft 212 on the rear side is respectively set in the corresponding rear inclined slot 22. Each movable U-shaped frame 213 on the front side is connected to a spring damper 217 through a mounting block 216. Each frame 29 is connected to an integrated sensor 215, and each movable U-shaped frame 213 on the rear side is connected to an elliptical clamping plate 214. The integrated sensor 215 includes at least a temperature sensor and a pressure sensor to realize the temperature measurement and deformation measurement of the busbar 35, monitor the status of the busbar 35 in a timely manner, realize early fault detection, reduce the risk of leakage and short circuit, and greatly improve the safety and reliability of power supply in coal mines. The elliptical clamping plate 214 moves inward and backward to clamp the busbar 35, preventing it from bending and contacting the busbar seat 34 under gravity during long-term use, thus avoiding damage to the outer casing of the busbar 35. The spring damper 217 moves inward and forward to compress the busbar seat 34, helping to maintain its position. A pressure sensor can also be installed inside the spring damper 217; when the busbar seat 34 loosens and moves backward, the pressure value changes, thus monitoring the position of the busbar seat 34.

[0045] The fixed ring 25 is rotatably connected to the rotating ring 26. The rotating ring 26 is provided with a set of power inclined grooves 27, and each power inclined groove 27 is provided with a power rod 28. Each power rod 28 is connected to the corresponding frame 29. By setting the power rods 28 in the power inclined grooves 27, when the rotating ring 26 rotates, it drives the power rods 28 to move, thereby realizing the synchronous movement of a set of elliptical clamps 214, integrated sensors 215 and spring dampers 217.

[0046] The workflow of this embodiment is as follows:

[0047] After connecting the busbar 35 to the circuit breaker 3, use bolts to install the busbar seat 34 onto the partition 11. Rotate the rotating ring 26, which drives the power rod 28 to move along the power inclined groove 27. The power rod 28 drives the frame 29, the round shaft 212, the movable U-frame 213, the elliptical clamping plate 214, the integrated sensor 215, the mounting block 216, and the spring damper 217 to move. The frame 29 drives the radial guide rod 210 to move along the T-frame 23. The round shaft 212 moves along the corresponding rear inclined groove 22 and front inclined groove 24. The round shaft 212 drives the front movable U-frame 213, the mounting block 216, and the spring damper 217 to move along the front inclined groove 24. The round shaft 212 drives the rear movable U-frame 213 and the elliptical clamping plate 214 to move along the rear inclined groove 22, so that the spring damper 217 presses against the busbar seat 34, and the elliptical clamping plate 214 and the integrated sensor 215 respectively contact the busbar 35. Fix the rotating ring 26.

[0048] Example 3: This example further elaborates on Example 1 or 2, and also includes an auxiliary installation component 4. The auxiliary installation component 4 includes symmetrical installation slots 41, each of which is connected to a set of auxiliary wheels 42. Each of the symmetrical installation slots 41 is connected to a connecting plate 43, and each of the symmetrical connecting plates 43 is provided with a straight edge groove 44. The curved edges 63 at both ends of the crankshaft 61 are respectively located within the corresponding straight edge grooves 44. Two sets of symmetrical external guide rods 19 are connected inside the housing 14. Each external guide rod 19 passes through one end of a corresponding installation slot 41. The housing 14 is provided with long through grooves 16 corresponding to the two sets of auxiliary wheels 42. Before the circuit breaker 3 is installed, the upper end of the auxiliary wheel 42 is higher than the housing 14. When the circuit breaker 3 is installed, the convex rail 32 contacts the auxiliary wheel 42 and moves along the convex groove rail 13, facilitating the installation of the circuit breaker 3.

[0049] The workflow of this embodiment is as follows:

[0050] Before installation, the intermediate curved section 62 is at its lowest point of travel, and the upper end of the auxiliary wheel 42 is higher than the housing 14. When installing the circuit breaker 3, the convex rail 32 contacts the auxiliary wheel 42, which moves along the convex groove rail 13, facilitating the installation of the circuit breaker 3. When the crankshaft 61 rotates, it drives the side curved section 63 to swing within the side straight groove 44. The side curved section 63 drives the connecting plate 43 to move, which in turn drives the mounting groove 41 to move along the outer guide rod 19. The mounting groove 41 then drives the auxiliary wheel 42 to move.

[0051] This device uses a position monitoring component 5 to monitor the position of the circuit breaker 3. After the circuit breaker 3 is installed, the vertical insertion rod 51 is inserted vertically into the monitoring hole 33, causing the vertical insertion rod 51 to compress the first spring 52, which in turn causes the first pressure sensor 53 to measure the pressure value. When the bolts loosen, as the circuit breaker 3 moves along the height direction, the first spring 52 recovers, and the pressure value measured by the first pressure sensor 53 changes. When the circuit breaker 3 moves along the groove track 13, since the inner diameter of the monitoring hole 33 is larger than the diameter of the vertical insertion rod 51, the mounting base 31 contacts the vertical insertion rod 51 at the edge of the monitoring hole 33, causing the vertical insertion rod 51 to swing and tilt. The square rod 514 compresses one side of the second spring 58 and stretches the other side of the second spring 58, causing the pressure value measured by the corresponding second pressure sensor 57 to change, thus realizing the monitoring of the movement of the circuit breaker 3 along the groove track 13.

[0052] This device employs a busbar monitoring component 2 to monitor and support the busbar 35. An integrated sensor 215 measures the temperature and deformation of the busbar 35, enabling timely monitoring of its condition and early fault detection. An elliptical clamping plate 214 moves inward and backward to clamp the busbar 35, preventing it from bending and contacting the busbar seat 34 under gravity during prolonged use, thus avoiding damage to the outer casing of the busbar 35. A spring damper 217 moves inward and forward, pressing against the busbar seat 34 to help maintain its position.

[0053] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
