Description

Technical Field

[0001] This invention belongs to the field of electrical monitoring technology, and more specifically, relates to an electrical condition monitoring device for electrical switch boxes. Background Technology

[0002] In today's society, which is highly dependent on electricity, the stable operation of electrical equipment is crucial for all industries. From large machinery in industrial production to household appliances in daily life, electrical equipment is ubiquitous. And ensuring the safe, reliable, and efficient operation of this equipment relies heavily on electrical equipment condition monitoring.

[0003] Chinese Patent CN111276875B discloses an electrical switch box with an electrical condition monitoring device. The box includes a cabinet for assembling electrical components, a cabinet door on one side, and an electrical monitoring cabinet on the upper side. A power cable extends into the top of the monitoring cabinet. A cable guide and fixing mechanism is located at the point where the power cable passes through the top of the monitoring cabinet. The power cable passes through a first current transformer and connects to a circuit breaker. The output cable of the circuit breaker passes through a second current transformer. A cable winding mechanism is located on one side of both the first and second current transformers. This invention can detect power supply failures and improve the stability and neatness of cable connections, thus solving the problem of unreasonable cable arrangement in existing electrical switch cabinets.

[0004] Currently, the installation and fixation of cables inside the switch cabinet are not secure enough, and the cables are prone to displacement, causing loose connections between the cables and internal components and affecting the stability of the power connection. In addition, even after reconnecting the cables, if the cables have aged due to long-term use, the circuit will still be unstable. Although existing electrical condition monitoring devices can detect the location of unstable lines, if there are many cables, it still takes time for staff to locate the specific location of the line. Moreover, if the electrical condition monitoring device is damaged due to environmental factors during use, the data monitoring and transmission will be unstable, affecting the monitoring.

[0005] Therefore, we propose an electrical condition monitoring device for electrical switch boxes to address the aforementioned problems. Summary of the Invention

[0006] In view of the existing technology, the connection between the power cable and the internal components is loose, which affects the stability of the power connection. In addition, although the electrical condition monitoring device can detect the location of unstable lines, if there are too many cables, the staff still need time to find and determine the specific location of the line. Moreover, if the electrical condition monitoring device is damaged due to environmental factors, the data monitoring and transmission will be unstable, affecting the monitoring problem. The purpose of this invention is to provide an electrical condition monitoring device for electrical switch boxes.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows: an electrical condition monitoring device for an electrical switch box, comprising a box and cables, a base plate fixedly connected to the bottom wall of the box, a terminal block fixedly connected to the top of the base plate, a wire insertion slot installed inside the terminal block, one end of each cable being inserted into the corresponding wire insertion slot, a wire insertion baffle fixedly connected to the side wall of the cable, an anti-loosening component installed at the top of the base plate, a protective component installed on the side wall of the terminal block, and a conversion component installed on the top wall of the box.

[0008] Furthermore, the anti-loosening component includes a mounting plate, which is fixedly connected to the top of the base plate. The top of the base plate has a plurality of first sliding grooves, and the bottom wall of each first sliding groove has a rectangular groove. Each first sliding groove has a sliding plate embedded in it, and the side wall of the sliding plate is symmetrically fixedly connected to a first spring.

[0009] Furthermore, one end of each of the first springs is fixedly connected to the side wall of the mounting plate, and an impact plate is fixedly connected to the top of each of the slide plates. Each of the impact plates is an arc-shaped structure and is slidably connected to the adjacent cable side wall. A first electromagnet is fixedly connected to the bottom wall of each of the rectangular grooves.

[0010] Furthermore, each of the rectangular grooves has a second spring symmetrically fixedly connected to its inner bottom wall, and two second springs are jointly fixedly connected to an inclined block. The inclined block is slidably connected to the inner wall of the adjacent rectangular groove, and a first permanent magnet is fixedly connected to the bottom wall of the inclined block.

[0011] Furthermore, the protective component includes a plurality of second slide grooves, each of which is formed outside the corresponding plug slot. The side wall of the terminal block is provided with a plurality of mounting slots, and each mounting slot is provided with a connection hole between it and the adjacent second slide groove.

[0012] Furthermore, a second electromagnet and a fourth permanent magnet are fixedly connected to the inner wall of each second slide groove, and a third spring is symmetrically fixedly connected to the inner wall of each second slide groove. The two third springs are jointly fixedly connected to an ejector ring, and the ejector ring is slidably connected to the inner wall of the second slide groove.

[0013] Furthermore, a second permanent magnet and a third permanent magnet are fixedly connected to the side wall of the ejector ring, a limit plate is slidably connected inside each of the mounting slots, a rectangular hole is opened at the top of the limit plate, and a fixing plate is fixedly connected to the bottom of each ejector ring.

[0014] Furthermore, one end of each of the fixed plates passes through an adjacent connecting hole and is fixedly connected to the top of the adjacent limiting plate. Multiple sets of fourth springs are fixedly connected to the top of the bottom plate. One end of each set of fourth springs is fixedly connected to a connecting plate. A partition is fixedly connected to the top of the connecting plate. The partition abuts against the bottom end of the adjacent limiting plate.

[0015] Furthermore, the conversion assembly includes a first monitoring device and a second monitoring device. The top of both the first and second monitoring devices is provided with a wiring groove. A motor is fixedly connected to the top wall of the housing. A motor shaft is fixedly connected to the output end of the motor. A conversion plate is fixedly connected to the side wall of the motor shaft. The first and second monitoring devices are symmetrically fixedly connected to the bottom of the conversion plate.

[0016] Furthermore, the top of the conversion plate is symmetrically provided with mounting holes, which are connected to the adjacent wiring slots. A data cable is installed on the top of the box. An electric push rod is fixedly connected to the top wall of the box. A lifting plate is fixedly connected to the movable end of the electric push rod. The lifting plate is fixedly connected to the data cable through it. The data cable is inserted into one of the wiring slots.

[0017] Compared with the prior art, the beneficial effects of the present invention are: By incorporating anti-loosening components, cables that have become loose can be re-secured and inserted. Under the elastic action of the first spring, the impact plate firmly abuts against the insertion baffle, ensuring that the loose cable is stably inserted into the insertion slot, preventing further loosening, improving the device's performance, preventing the circuit from being in a loose state for a long time, which could lead to serious circuit disasters, and enhancing the device's safety. Furthermore, by incorporating anti-loosening components, loose lines can be secured in a timely manner, effectively reducing the workload of maintenance personnel and improving the device's practicality. By incorporating a protective component, when the second electromagnet is energized, the generated magnetic repulsion pushes the ejector ring away from the second slot. Under the elastic force of the third spring, it begins to extend and reset, further pushing the ejector ring away from the second slot. As the ejector ring leaves the second slot, it contacts the cable insertion baffle and pushes the cable to move synchronously, thus ejecting the cable from the insertion slot and disconnecting the cable connection, improving device safety. By incorporating a switching component, when line instability frequently occurs, the positions of the first and second monitoring devices are switched. The lifting plate contacts the end of the data cable. As most data cables have rigid ends, the connection point will not completely break during the up-and-down movement of the lifting plate, thus not affecting normal wiring operations. By switching the first monitoring device to the backup second monitoring device, damage to the first monitoring device can effectively prevent disruption to normal monitoring operations, improving the device's performance.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] To address the issue of insufficiently secure installation of cable 3 upon entering the switch cabinet, leading to displacement of cable 3 and loosening of its connection to internal components, thus affecting power connection stability, the following measures are taken: Figure 1 - Figure 5 and Figure 9 - Figure 10 As shown: An electrical condition monitoring device for an electrical switch box includes a box body 1 and cables 3. A base plate 11 is fixedly connected to the bottom wall of the box body 1, and a terminal block 2 is fixedly connected to the top of the base plate 11. A wire insertion slot 21 is installed inside the terminal block 2, and one end of each cable 3 is inserted into the corresponding wire insertion slot 21. One end of the cables 3 inside the electrical switch box is inserted into the terminal block 2 to achieve circuit connection. A wire insertion baffle 31 is fixedly connected to the side wall of the cables 3. An anti-loosening component 4 is installed at the top of the base plate 11. By setting the anti-loosening component 4, the device can monitor the electrical condition of the cables. The loose cable 3 is re-secured and inserted, and under the elastic action of the first spring 42, the impact plate 44 presses tightly against the insertion baffle 31, so that the loose cable 3 is stably inserted into the insertion slot 21, preventing it from loosening again, improving the device's performance, preventing the circuit from being in a loose state for a long time, which could seriously cause circuit disasters, and improving the device's safety. In addition, by setting the anti-loosening component 4, the loose line can be secured and inserted in time, effectively reducing the maintenance workload of the staff and improving the device's practicality.

[0022] A protective component 5 is installed on the side wall of the terminal block 2. By setting the protective component 5, after the second electromagnet 514 is energized, the generated magnetic repulsion force pushes the ejection ring 55 away from the inside of the second slide groove 51. Under the elastic action of the third spring 54, it begins to extend and reset, pushing the ejection ring 55 away from the inside of the second slide groove 51. After the ejection ring 55 leaves the inside of the second slide groove 51, it contacts the wire insertion baffle 31 and pushes the cable 3 to move synchronously, thereby pushing the cable 3 out from the inside of the wire insertion slot 21, so that the cable 3 is disconnected and the safety of the device is improved.

[0023] A conversion component 6 is installed on the top wall inside the housing 1. By setting the conversion component 6, when the line output is frequently unstable, the system can switch to the backup second monitoring device 62 for monitoring. This can effectively prevent the normal monitoring operation from being affected if the first monitoring device 61 is damaged, thus improving the effectiveness of the device.

[0024] The anti-loosening component 4 includes a mounting plate 41, which is fixedly connected to the top of the base plate 11. The top of the base plate 11 has a plurality of first sliding grooves 49. Each first sliding groove 49 has a rectangular groove 410 on its inner bottom wall. Each first sliding groove 49 has a sliding plate 43 embedded inside it. The side wall of the sliding plate 43 is symmetrically fixedly connected to a first spring 42.

[0025] One end of each first spring 42 is fixedly connected to the side wall of the mounting plate 41, and an impact plate 44 is fixedly connected to the top of each slide plate 43. Each impact plate 44 is an arc-shaped structure and is slidably connected to the side wall of the adjacent cable 3. A first electromagnet 47 is fixedly connected to the bottom wall of each rectangular groove 410.

[0026] Each rectangular groove 410 has a second spring 46 symmetrically fixedly connected to its inner bottom wall. The two second springs 46 are fixedly connected to a wedge 45. The wedge 45 is slidably connected to the inner wall of the adjacent rectangular groove 410. The bottom wall of the wedge 45 is fixedly connected to a first permanent magnet 48.

[0027] In this solution: by setting an anti-loosening component 4, during use, the first monitoring device 61 monitors the working cable 3 inside the housing. If the connection between the cable 3 and the socket 21 becomes loose, the corresponding circuit current will become unstable. At this time, the first monitoring device 61 can pinpoint the specific circuit with unstable current. Then, the first electromagnet 47 at the corresponding position is energized, and its end generates a magnetic pole. The magnetic poles of the adjacent end faces of the first electromagnet 47 and the first permanent magnet 48 are opposite magnetic poles. Under the action of the generated magnetic attraction, the inclined block 45 is driven to move downward. At this time, the first spring 42 is in a compressed state until the inclined block 45 enters the rectangular groove 410, releasing the limiting effect of the inclined block 45 on the slide plate 43. Under the elastic action of the first spring 42, it extends, driving the slide plate 43 and impact. The impact plate 44 approaches the insertion baffle 31 and impacts the insertion baffle 31, causing the cable 3 to move closer to the insertion slot 21. This re-secures the cable 3 at the point of loosening. Under the elastic action of the first spring 42, the impact plate 44 presses firmly against the insertion baffle 31, ensuring that the loose cable 3 is stably inserted into the insertion slot 21, preventing it from loosening again, improving the device's performance, preventing the circuit from being in a loose state for a long time, which could seriously cause circuit disasters, and improving the device's safety. Furthermore, by setting the anti-loosening component 4, the loosened wires can be secured in time, effectively reducing the workload of maintenance personnel and improving the device's practicality. The sliding plate 43 can de-energize the first electromagnet 47 after passing the inclined block 45, preventing continuous energization and energy loss. During subsequent centralized maintenance by staff, simply reverse the impact plate 44 and use the inclined surface of the inclined block 45 to push the inclined block 45 into the rectangular groove 410. After the slide plate 43 leaves the inclined block 45, the elastic action of the second spring 46 pushes the inclined block 45 back to its original position, thus limiting the slide plate 43 again for subsequent use.

[0028] To address the issue that even after reconnecting cable 3, aging due to prolonged use might still cause circuit instability, and while existing electrical condition monitoring devices can detect locations of instability, if there are many cables 3, it still requires time for staff to pinpoint the exact location. Figure 5 - Figure 8 and Figure 11 As shown: The protective component 5 includes multiple second slides 51, each of which is opened outside the corresponding wire slot 21. The side wall of the terminal block 2 is provided with multiple mounting slots 53, and each mounting slot 53 is provided with a connection hole 52 between it and the adjacent second slide 51.

[0029] Each second slide groove 51 has a second electromagnet 514 and a fourth permanent magnet 515 fixedly connected to its inner sidewall. Each second slide groove 51 has a third spring 54 fixedly connected to its inner sidewall. The two third springs 54 are fixedly connected to an ejector ring 55, which is slidably connected to the inner wall of the second slide groove 51.

[0030] The ejector ring 55 is fixedly connected to the side wall with a second permanent magnet 56 and a third permanent magnet 512. Each mounting groove 53 is slidably connected to a limit plate 510. The limit plate 510 has a rectangular hole 511 at the top. Each ejector ring 55 is fixedly connected to the bottom end with a fixing plate 513.

[0031] One end of each fixed plate 513 passes through the adjacent connecting hole 52 and is fixedly connected to the top of the adjacent limiting plate 510. Multiple sets of fourth springs 57 are fixedly connected to the top of the base plate 11. One end of each set of fourth springs 57 is fixedly connected to a connecting plate 58. A partition plate 59 is fixedly connected to the top of the connecting plate 58. The partition plate 59 abuts against the bottom of the adjacent limiting plate 510.

[0032] In this solution: by setting up protective component 5, if cable 3 becomes loose due to aging during use, the loose cable 3 will be reconnected promptly. Since cable 3 is aging and poses a safety hazard, it needs to be replaced immediately. If, after reconnection, the first monitoring device 61 still detects circuit instability in the reconnected cable, it indicates that cable 3 is aging and the circuit needs to be disconnected and repaired immediately. At this time, the second electromagnet 514 is energized. The second electromagnet 514 generates magnetic poles, and the adjacent end faces of the second electromagnet 514 and the second permanent magnet 56 have the same magnetism. Under the action of the generated magnetic repulsion, the ejector ring 55 is pushed. As the ejector ring 55 moves away from the second slide groove 51, the combined magnetic repulsion between the second electromagnet 514 and the second permanent magnet 56 and the force of the third spring 54 are greater than the magnetic attraction between the fourth permanent magnet 515 and the third permanent magnet 512. As the ejector ring 55 moves, the fourth permanent magnet 515 separates from the third permanent magnet 512 and gradually moves away. Then, under the elastic action of the third spring 54, it begins to extend and reset, pushing the ejector ring 55 away from the second slide groove 51. After the ejector ring 55 leaves the second slide groove 51, it contacts the wire insertion baffle 31 and pushes the cable 3 to move synchronously, thereby ejecting the cable 3 from the wire insertion slot 21 and disconnecting the cable 3. Because an electric arc may occur during the process of cable 3 leaving the insertion slot 21, the limiting plate 510 moves synchronously through the fixing plate 513 as the ejector ring 55 leaves the second slide groove 51. During the movement, the partition plate 59 moves upward through the rectangular hole 511 under the action of the fourth spring 57. The moving partition plate 59 seals the insertion slot 21, interrupting the electric arc in time, avoiding electrical disasters caused by the electric arc, and improving the safety of the device. When the staff performs maintenance, they only need to observe where cable 3 has fallen off to identify that cable 3 has aged and needs to be replaced. During the replacement process, the partition plate 59 is pushed downward and the ejector ring 55 is pushed into the second slide groove 51. Under the magnetic attraction of the fourth permanent magnet 515 and the third permanent magnet 512, the ejector ring 55 is attracted and fixed for continued use.

[0033] To address the issue of unstable data transmission and impacted monitoring caused by environmental factors damaging electrical condition monitoring devices during operation, such as... Figure 1 and Figure 12 - Figure 13 As shown: The conversion component 6 includes a first monitoring device 61 and a second monitoring device 62. Both the first monitoring device 61 and the second monitoring device 62 are provided with wiring slots 63 at their top ends. A motor 66 is fixedly connected to the top wall inside the housing 1. A motor shaft 610 is fixedly connected to the output end of the motor 66. A conversion plate 64 is fixedly connected to the side wall of the motor shaft 610. The first monitoring device 61 and the second monitoring device 62 are symmetrically fixedly connected to the bottom end of the conversion plate 64.

[0034] The top of the conversion plate 64 is symmetrically provided with mounting holes 65, which are connected to the adjacent wiring slots 63. A data cable 67 is installed on the top of the box 1. An electric push rod 68 is fixedly connected to the top wall of the box 1. A lifting plate 69 is fixedly connected to the movable end of the electric push rod 68. The lifting plate 69 and the data cable 67 are fixedly connected through it. The data cable 67 is inserted into one of the wiring slots 63.

[0035] In this solution: A conversion component 6 is set up, in which the first monitoring device 61 is in a normal connected and operational state, and the second monitoring device 62 is in a disconnected state for backup. When line output instability frequently occurs, the electric push rod 68 is activated. The movable end of the electric push rod 68 retracts, causing the lifting plate 69 to move upward, thereby pulling the data cable 67 out of the wiring slot 63 and disconnecting the first monitoring device 61. Subsequently, the motor 66 is activated, driving the motor shaft 610 to rotate, causing the conversion plate 64 to rotate 180 degrees, switching the positions of the first monitoring device 61 and the second monitoring device 62, so that the backup second monitoring device 62 rotates to directly below the data cable 67. At this time, the electric push rod 68 is activated, extending and driving the data cable 67 downward until the connector end of the data cable 67 is inserted into the wiring slot 63 at the top of the second monitoring device 62, completing the position switch between the first monitoring device 61 and the second monitoring device 62. The lifting plate 69 contacts the end of the data cable 67. According to existing technology, most data cables 67 have rigid ends, so the connector end of the data cable 67 will not completely break during the up-and-down movement of the lifting plate 69, thus not affecting normal wiring operations. By switching to the backup second monitoring device 62 for monitoring, it is possible to effectively avoid affecting normal monitoring operations if the first monitoring device 61 is damaged, thus improving the device's effectiveness.
