Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power distribution cabinets, and more specifically, to an intelligent power distribution cabinet with temperature early warning feedback. Background Art

[0002] As the core carrier of the terminal equipment of the power system, the intelligent distribution cabinet realizes remote monitoring and automatic management of electrical components by integrating the Internet of Things technology. In the current technology, the distribution cabinet usually adopts distributed temperature sensors or local infrared temperature measurement modules, combined with the control module to trigger the cooling device to realize temperature abnormality warning. Its technical logic is that when the local temperature exceeds the threshold, the sound and light alarm or the linkage heat dissipation module is used to prevent the components from overheating and damage.

[0003] However, the current temperature monitoring system has the problem of blind spots in actual operation. Due to the space limitations of traditional sensor layout, only single-point sensors can be set on the side walls of the cabinet. The configured sensors are limited by fixed viewing angles and cannot cover the entire heat distribution in complex wiring environments. When there are multiple layers of electrical components or hidden hot spots inside the distribution cabinet, some current solutions have difficulty in achieving full-area temperature perception, which may delay early warning responses. For this reason, some technologies have attempted to introduce infrared thermal imaging technology to improve monitoring accuracy, but due to the limitations of equipment deployment methods and costs, the problem of full coverage has not yet been solved.

[0004] Further analysis revealed that the core contradiction of the current infrared detection system is that it is difficult to build a 360-degree monitoring network without blind spots inside the distribution cabinet. The space inside the cabinet is compact, and traditional thermal imagers need to occupy a large installation position, which makes it difficult to deploy multiple devices redundantly. The dynamic distribution of heat sources requires the detection system to have real-time multi-angle scanning capabilities. However, some current solutions rely on statically installed single-point thermal imagers, which cannot synchronously capture temperature gradient changes in three-dimensional space.

[0024] The following is a detailed description of an intelligent power distribution cabinet with temperature warning feedback provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternative methods can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 8 As shown, an embodiment of the present invention provides an intelligent power distribution cabinet with temperature warning feedback, including a power distribution cabinet body 1 and a wiring component group 2 fixedly installed inside the power distribution cabinet body 1, the top of the power distribution cabinet body 1 is configured with a first multi-stage regulating mechanism 3, the first multi-stage regulating mechanism 3 includes a runway-shaped casing 31, a runway-shaped guide rail 34 is fixedly connected to the outer edge position of the runway-shaped casing 31, a surrounding guide mechanism 4 extending inside the power distribution cabinet body 1 is configured on the runway-shaped guide rail 34, and a plurality of groups of first infrared temperature control units 5 facing the wiring component group 2 are configured on the surrounding guide mechanism 4; The first air guide module 36 and the second air guide module 37 are respectively installed at the two side ends of the racetrack-shaped casing 31, and a first servo motor 32 for driving the first air guide module 36 and the second air guide module 37 to rotate and ventilate is arranged at the axis of the racetrack-shaped casing 31, and a self-starting and stopping module 38 for connecting the surrounding guide mechanism 4 is also arranged at one side of the output end of the first servo motor 32; Among them, the connection state between the output end of the first servo motor 32 and the surround guide mechanism 4 is controlled by the self-start and stop module 38. When the first air guide module 36 and the second air guide module 37 are in the heat dissipation working state, the surround guide mechanism 4 can be turned on to drive the first infrared temperature control unit 5 to perform 360-degree temperature detection around the wiring element group 2 when the temperature exceeds the warning temperature.

[0026] In order to solve the problem of monitoring blind spots in the existing distribution cabinet temperature monitoring system caused by the limitation of sensor layout space and insufficient deployment of static single-point thermal imaging equipment, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of a distribution cabinet body 1, a wiring component group 2, a first multi-level control mechanism 3, and a surround guide mechanism 4. The distribution cabinet body 1 and the wiring component group 2 are the inherent structures of the intelligent distribution cabinet in the prior art. The distribution cabinet body 1 is the basic structure of the distribution cabinet, which mainly undertakes protection, support and integration functions. It is made of cold-rolled steel plate and its surface is treated with electrostatic spraying. It has the properties of corrosion resistance, dust resistance, waterproofness, etc., and meets the fire prevention requirements. The cabinet body is divided into a front panel, side panels, a base and other parts. The front panel is provided with switches and indicator lights for easy operation. The side panels are installed with high-voltage or low-voltage switchgear, and the base provides stable support. The configured wiring component group 2 is a collection of electrical components for realizing power distribution, control and protection in the distribution cabinet, generally including circuit breakers, busbar systems, control components, measurement and monitoring equipment, etc., to feedback the grid parameters in real time. In the working state, the circuit integration between components is realized through connectors such as busbars and cable connectors to form a complete distribution network.

[0027] Among them, the configured first multi-level control mechanism 3 and the surround guide mechanism 4 are used to constitute a system that can perform 360-degree temperature monitoring inside the distribution cabinet body 1. The first multi-level control mechanism 3, as the main control structure, can provide the surround guide mechanism 4 with a runway-shaped guide rail 34 that can surround the wiring element group 2, so that the surround guide mechanism 4 can stably perform 360-degree temperature monitoring on the outside of the wiring element group 2 along the runway-shaped guide rail 34 to provide real-time feedback on the temperature changes at any position inside. The first multi-level control mechanism 3, which also serves as the driving end, is configured with a driving end that, on the one hand, drives the first air guide module 36 and the second air guide module 37 on both sides to rotate, forming a flow duct that inhales air from the outside and simultaneously discharges hot air to the outside, to neutralize the internal heat and achieve real-time cooling. On the other hand, the hot air inside is taken away through the flow duct, which can also provide a relatively stable monitoring environment for the surround guide mechanism 4, reduce the impact of the internal heat of the system on the heat of a single area, and improve the accuracy of monitoring.

[0028] In the working state, it is only necessary to control the connection state between the output end of the first servo motor 32 and the surround guide mechanism 4 through the self-start and stop module 38, that is, by utilizing the effect of magnetic attraction, when the first air guide module 36 and the second air guide module 37 are in the heat dissipation working state, the surround guide mechanism 4 can be turned on to drive the first infrared temperature control unit 5 to perform 360-degree temperature monitoring around the wiring element group 2 when the temperature exceeds the warning temperature, so as to solve the problem of monitoring blind spots caused by the limitation of sensor layout space and insufficient deployment of static single-point thermal imaging equipment in the existing distribution cabinet temperature monitoring system.

[0029] like Figures 1 to 8 As shown, a first servo motor 32 is fixedly installed at the bottom axis position of the racetrack-shaped casing 31, the output end of the first servo motor 32 passes through the upper side of the racetrack-shaped casing 31, and a first gear plate 33 is fixedly installed, and reserved openings 35 that penetrate into the interior of the power distribution cabinet 1 are opened at both side ends of the racetrack-shaped casing 31, and a first air guide module 36 and a second air guide module 37 are fixedly installed through the reserved openings 35 at the two side ends, and the second air guide module 37 includes a circular ring sleeve 371, a first circular ring groove rail 372 is opened on the inner wall of the circular ring sleeve 371, and an embedded circular ring frame 373 is movably installed through the first circular ring groove rail 372, and a gear outer ring 374 is fixedly installed on the outer edge of the embedded circular ring frame 373.

[0030] Among them, the configured first servo motor 32 is a motor structure capable of servo drive in the prior art, which is the core driving actuator in the device and is mainly used to convert electrical signals into mechanical motion. It drives the mechanical parts to achieve precise displacement, speed or torque output by receiving the instructions of the controller. There is no self-rotation phenomenon in the working state. It is a prior art that drives the first gear plate 33 to rotate through the first servo motor 32. The reserved openings 35 on both sides of the top of the distribution cabinet body 1 are for the purpose of cooperating with the two sets of first air guide modules 36 and second air guide modules 37 for heat dissipation.

[0031] like Figures 1 to 8 As shown, the first wind guide module 36 and the second wind guide module 37 have the same structure consisting of a circular ring sleeve 371, a first circular ring groove 372, an embedded circular ring frame 373, and a gear outer ring 374, and the gear outer rings 374 on the first wind guide module 36 and the second wind guide module 37 are respectively meshed with the two sides of the first gear plate 33, and the inner wall of the gear outer ring 374 in the second wind guide module 37 is fixedly installed with a fan blade group 375, and the inner wall of the gear outer ring 374 in the first wind guide module 36 is fixedly installed with a fan blade group 375 opposite to the blades of the fan blade group 375 in the second wind guide module 37.

[0032] Among them, the first air guide module 36 and the second air guide module 37 are configured with the same overall structure, the difference is that the fan blades of the fan blade group 375 in the first air guide module 36 are opposite to the fan blades of the fan blade group 375 in the second air guide module 37. The opposite fan blade structure is set to form the above-mentioned flow air duct that sucks air from the outside and synchronously discharges hot air to the outside, and the first air guide module 36 and the second air guide module 37 are not both configured with a driving end, but are driven by the first servo motor 32 at the axial position of the runway-shaped casing 31, and the first servo motor 32 drives the first gear plate 33 at the output end to rotate, thereby synchronously driving the meshing gear outer ring 374 on both sides to rotate.

[0033] like Figures 1 to 8 As shown, the automatic start-stop module 38 includes an electromagnet unit 381 fixedly mounted on the upper surface of the first gear plate 33, a circular magnetic sleeve 382 is sleeved on the outer adsorption end of the electromagnet unit 381, a telescopic slide rod 383 is fixedly connected to the outer side of the circular magnetic sleeve 382, ​​a round-mouthed ring 384 is fixedly connected to the protruding end of the telescopic slide rod 383, an articulated sleeve rod 385 is movably sleeved on the sleeve end of the round-mouthed ring 384, and the articulated sleeve rod 385 is movably sleeved in the runway-shaped guide rail 34 as a whole, a first high-strength magnetic head 386 that fits the bottom surface of the runway-shaped guide rail 34 is fixedly mounted on the bottom of the articulated sleeve rod 385, and a limiting slot 387 for the first high-strength magnetic head 386 to slide is provided at the inner bottom of the runway-shaped guide rail 34.

[0034] Among them, the self-start and stop module 38 is configured to further borrow the driving force of the output end of the first servo motor 32, and at the same time to ensure that in the working state, that is, the first air guide module 36 and the second air guide module 37 are under the overall heat dissipation, the surround guide mechanism 4 can be timely connected to drive the first infrared temperature control unit 5 to perform 360-degree temperature detection around the wiring element group 2 when the temperature exceeds the warning temperature, so as to improve the synergy of the driving force between the feedback ends. The specific process of borrowing the driving force of the first servo motor 32 through the self-start and stop module 38 is as follows: when the hot air exceeds the warning temperature through the air guide, the first servo motor 32 is driven by the first servo motor 32. In the case of temperature warning, the adsorption end can be opened by the electromagnet unit 381, so that the adsorption end of the electromagnet unit 381 is adsorbed together with the annular magnetic sleeve 382 to form a temporarily integrated structure. As the first gear plate 33 continues to rotate, the annular magnetic sleeve 382 will be driven to rotate synchronously, and the outer side of the annular magnetic sleeve 382 is connected to the articulated sleeve head rod 385 through the telescopic slide rod 383. Therefore, the first gear plate 33 can also pull one end of the articulated sleeve head rod 385 to move along the runway-shaped guide rail 34, so that it drives the surrounding guide mechanism 4 at the bottom to move in a surrounding manner.

[0035] The so-called electromagnet unit 381 is an electrically controlled magnet structure in the prior art, an electromagnet device that controls the generation and disappearance of a magnetic field by electric current, and its core is composed of a coil, an iron core, and an armature, and its adsorption end, that is, the outer annular surface and the annular magnetic suction sleeve 382 are adsorbed together by electric current. It can rotate together, or close its adsorption end, that is, the outer annular surface and the annular magnetic suction sleeve 382 do not interfere with each other, and the annular magnetic suction sleeve 382 does not rotate when the electromagnet unit 381 is rotating. The telescopic slide rod 383 is a telescopic rod structure with two sliding sleeves, because the rotation range of the first gear disc 33 is a circle, and the runway-shaped guide rail 34 is a structure similar to a runway shape, so in the process of pulling the articulated sleeve rod 385 by rotating the first gear disc 33, it is necessary to change the length of the pulling end in real time to adapt to the rotation radius of the runway-shaped guide rail 34. The hinged sleeve rod 385 is integrally sleeved inside the runway-shaped guide rail 34 and is movably connected to the telescopic slide rod 383 via a round sleeve ring 384 .

[0036] like Figures 1 to 8 As shown, the surround guide mechanism 4 includes a second high-strength magnetic head 41 adsorbed on the bottom of the first high-strength magnetic head 386 via a runway-shaped guide rail 34, a second servo motor 42 is fixedly installed on the bottom of the second high-strength magnetic head 41, a limit frame 43 is fixedly installed on the bottom of the second servo motor 42, a ball sleeve 6 is movably installed on the bottom of the limit frame 43, a groove for the ball sleeve 6 to slide is provided at the inner bottom of the distribution cabinet body 1, the output end of the second servo motor 42 is passed through the inner top of the limit frame 43, and a threaded rod 44 is fixedly installed on the output end and is integrally placed inside the limit frame 43, and a plurality of first infrared temperature control units 5 are fixedly installed on the side of the surface of the limit frame 43 facing the wiring element group 2.

[0037] Among them, the second high-strength magnetic head 41 is configured with the same structure as the first high-strength magnetic head 386, and both are magnetic head structures in the prior art that can be adsorbed together by high-strength magnetic attraction. Because the runway-shaped guide rail 34 on the runway-shaped shell 31 needs to provide a complete runway-shaped moving path, and it cannot be completed by directly opening a runway-shaped groove, so two magnetic heads are used for adsorption connection, so that the second high-strength magnetic head 41 is adsorbed to the bottom of the first high-strength magnetic head 386 through the bottom surface of the runway-shaped guide rail 34. In order to ensure the stability of the adsorption end, on the one hand, a high-strength magnetic head needs to be used, and on the other hand, the thinness of the bottom surface of the runway-shaped guide rail 34 needs to be ensured.

[0038] The specific working state of the surround guide mechanism 4 is: first, the adsorption end face is opened by the electromagnet unit 381 to form a whole with the circular magnetic suction sleeve 382, ​​and the first gear plate 33 is rotated to cooperate with the adaptive length adjustment function of the telescopic slide rod 383 to pull the hinged sleeve rod 385 on one side of the circular mouth ring 384 to rotate inside the runway-shaped guide rail 34, and then during the movement of the hinged sleeve rod 385, the first high-strength magnetic suction head 386 arranged at the bottom thereof adsorbs the second high-strength magnetic suction head 41 at the bottom, so that the limit frame 43 rotates around the wiring component group 2 inside the distribution cabinet body 1. During the rotation, the ball sleeve 6 arranged at the bottom of the limit frame 43 can also provide auxiliary support force, and the surround movement trajectory is used to enable the first infrared temperature control unit 5 to monitor the temperature of each side of the wiring component group 2.

[0039] Among them, the configured first infrared temperature control unit 5 is a non-contact temperature detection structure in the prior art. Through the infrared radiation energy monitoring function of the non-contact infrared temperature sensor, the temperature status of each side of the wiring element group 2 is monitored in real time, thereby realizing real-time monitoring and overheating warning of the internal equipment temperature of the distribution cabinet. It can periodically detect the surface temperature of the wiring elements and identify abnormal temperature rise to avoid equipment damage or fire risks caused by line overload or poor contact. The motion trajectory of the surround guide mechanism 4 is used to cover the multi-angle positions of the wiring element group 2 to achieve all-round temperature scanning. The temperature data can be transmitted to the control system through the communication module to provide a basis for subsequent temperature control strategies.

[0040] like Figures 1 to 8 As shown, the limit frame 43 is also provided with a second multi-stage regulating mechanism 7, which includes a nut sleeve block 71 slidably installed inside the limit frame 43 and meshing with the threaded rod 44, and the nut sleeve block 71 is fixedly installed with a U-shaped sleeve shaft 72 on the side facing the wiring element group 2, and a third servo motor 73 is fixedly installed on the side of the U-shaped sleeve shaft 72, and the output end of the third servo motor 73 passes through the interior of the U-shaped sleeve shaft 72 and is fixedly installed with an electric telescopic rod 74, and the electric telescopic rod 74 is integrally movably hinged inside the U-shaped sleeve shaft 72, and a fourth servo motor 75 parallel to the third servo motor 73 is fixedly installed on the output end of the electric telescopic rod 74, and an extension rod 76 is fixedly installed on the output end of the fourth servo motor 75, and the extension rod 76 is L-shaped as a whole.

[0041] The second multi-stage regulating mechanism 7 is mainly used to adjust the direction of the electrically controlled outward expansion module 8 .

[0042] like Figures 1 to 8As shown, the extended end of the extension rod 76 is also provided with an electrically controlled external expansion module 8, and the electrically controlled external expansion module 8 includes a bidirectionally articulated electric telescopic rod 81 fixedly mounted on the extended end of the extension rod 76, and L-shaped articulated sleeves 82 are movably mounted on the articulated output ends on both sides of the bidirectionally articulated electric telescopic rod 81, and the extended ends of the two groups of L-shaped articulated sleeves 82 are fixedly connected with a connecting hinge 83, and the outer sides of the connecting hinge 83 are fixedly connected with an L-shaped extension plate 84 parallel to the L-shaped articulated sleeve 82 on the same side, and the two groups of L-shaped articulated sleeves 82 are hinged to the bottom of the bidirectionally articulated electric telescopic rod 81 through the connecting hinge 83.

[0043] like Figures 1 to 8 As shown, the outer side of the L-shaped extension plate 84 is also provided with a variable circular guide rail mechanism 9, and the variable circular guide rail mechanism 9 includes a semi-circular guide rail 91 fixedly installed on the outer sides of the two groups of L-shaped extension plates 84, and the surface of the semi-circular guide rail 91 is provided with a second circular groove rail 92, and a tooth block 94 is fixedly installed on one edge of the inner bottom of the second circular groove rail 92, and a magnetic coating 95 is fixedly installed on the other edge, and a limiting stop ring 93 is fixedly installed on the upper side wall of the magnetic coating 95 in the second circular groove rail 92, and a magnetic positioning coating 910 is fixedly installed on both side end faces of the semi-circular guide rail 91, and the semi-circular guide rails 91 on the outer sides of the two groups of L-shaped extension plates 84 can be adsorbed and tightly attached to form a complete circular structure through the magnetic positioning coating 910.

[0044] like Figures 1 to 8 As shown, the variable annular guide rail mechanism 9 also includes a fifth servo motor 97 which is sleeved in a second annular groove rail 92 on one side, and a second gear plate 96 is fixedly mounted on the output end of the fifth servo motor 97. The second gear plate 96 is clamped as a whole at the bottom of the limit stop ring 93 and adsorbed on the magnetic coating 95. A plastic support rod 98 is fixedly mounted on one end of the outer surface of the fifth servo motor 97 away from the fifth servo motor 97, and a second infrared temperature control unit 99 is fixedly mounted on the outer side of the plastic support rod 98.

[0045] Among them, the configured second infrared temperature control unit 99 is a more specific detection module different from the first infrared temperature control unit 5. In the actual working process, the traditional fixed-point monitoring mechanism cannot change the monitoring direction with the first infrared temperature control unit 5 controlled by the surround guide mechanism 4 during the temperature monitoring process. Therefore, a dynamic detection system is established through the first multi-level control mechanism 3 and the surround guide mechanism 4. Furthermore, there are many structures on the wiring component group 2, and the temperature of each structure is different when it is in working state and in fault state. Because the air flow in the component-dense area is poor, a heat island effect is formed, and the heat dissipation in the open area is faster. The temperature rise correlation of the current-induced heating type equipment is strong, and the temperature difference between different parts of a single device is also large, resulting in uneven distribution of temperature points. The uneven temperature distribution inside the distribution cabinet is mainly caused by differences in material properties, contact resistance, operating conditions and heat dissipation conditions of different components, and the temperature is divergent, that is, different heating components may still exist in the same abnormal temperature area, so it is necessary to further detect specific points.

[0046] In the above context, the cooperation of the second multi-stage regulating mechanism 7 and the variable circular guide mechanism 9 constitutes a system that enables the second infrared temperature control unit 99 to further monitor the temperature around the interface wire, which is specifically: First, during the detection process of the first infrared temperature control unit 5 driven by the surround guide mechanism 4, when the temperature of a certain area is found to be abnormal, the second servo motor 42 outside the limit frame 43 can be used to drive the second multi-stage control mechanism 7 to move in the up and down direction of the limit frame 43 by utilizing the rotation of the threaded rod 44 at the output end of the second servo motor 42 to approach the first infrared temperature control unit 5 where the temperature abnormality is detected, that is, to move the nut sleeve 71 to the position of the first infrared temperature control unit 5 where the temperature abnormality is detected; Then, through the servo driving action of the output end of the third servo motor 73 on the side of the U-shaped sleeve shaft 72, the electric telescopic rod 74 hinged inside is controlled to flip up and down, so that the outer end of the electric telescopic rod 74 can be closer to the heating point, and then the driving force of the output end of the fourth servo motor 75 on the outside is controlled to rotate the extension rod 76, so that the electric control expansion module 8 can be close to the heating point without interfering with the electronic component structure; Then, by using the two hinged electric telescopic ends configured on the bidirectional hinged electric telescopic rod 81, the electric telescopic ends are retracted inward to tighten the two sets of hinged L-shaped hinged sleeves 82, and the outer side of the L-shaped extension plate 84 is expanded outward like a pair of scissors in the prior art, so that the two semi-circular guide rails 91 are opened, and then the two opened semi-circular guide rails 91 are placed against the position of the wire joint to be detected, and the bidirectional hinged electric telescopic rod 81 is expanded outward again to make the L-shaped extension plate 84 move inward, and the two semi-circular guide rails 91 are formed into a complete circular structure, so that the second infrared temperature control unit 99 can rotate 360 ​​degrees on the circular structure to perform covering monitoring on the interface end.

[0047] When the second infrared temperature control unit 99 is working, one end of the surrounding guide mechanism 4 is disconnected, that is, the electromagnet unit 381 is closed. The so-called two-way articulated electric telescopic rod 81 is two electric telescopic ends that are both hinged by activities, which are used to control the expansion and retraction of the L-shaped articulated sleeve 82 to simulate the expansion of scissors.

[0048] Because of the specific situation of the contact interface end, it is necessary to construct a circular ring structure that can be sleeved on the outside of the wire for the second infrared temperature control unit 99 to move, so two semi-circular guide rails 91 that can form a complete circular ring are provided, and each semi-circular guide rail 91 has a magnetic positioning coating 910 on its side end surface, so that the two semi-circular rings can fit more closely when fitting, and the interior of the semi-circular guide rail 91 forms a structure that can clamp the second gear plate 96 through a limit ring 93 and a magnetic coating 95, so that the second gear plate 96 will not fall out of the second circular groove rail 92 under any condition, and the fifth servo motor 97 configured on the outside of the second gear plate 96 is also clamped inside the second circular groove rail 92 as a whole, and driven by the output end of the fifth servo motor 97, the second gear plate 96 bites the tooth block 94 at the bottom of the second circular groove rail 92 to move.

[0049] like Figures 1 to 8 As shown, a deflector 388 is fixedly installed at the bottom of the runway-shaped casing 31 at the side end of a reserved opening 35 on one side, and a gas hose 10 is connected to the bottom of the deflector 388. An air duct 85 is fixedly installed on the outer side of the L-shaped extension plate 84, and a plurality of air outlet openings 86 are provided on the surface of the air duct 85. The side of the air hose 10 away from the deflector 388 is connected to two groups of air ducts 85 through a Y-shaped tube.

[0050] Among them, the air deflector 388 is configured to further utilize the wind generated at the position of the first air guide module 36. Because when the second infrared temperature control unit 99 subsequently detects the components in a single position area, the stability of the large environment in the cabinet will affect the monitoring of a certain point. Therefore, the air deflector 388 is used to appropriately introduce part of the wind flow into the gas supply hose 10, and then transported to the air guide 85 on the L-shaped extension plate 84 through the gas supply hose 10, and finally discharged through the air outlet 86 on the air guide 85, so that the outside of the detection area of ​​the second infrared temperature control unit 99 can further introduce wind flow, further reduce the interference of the outside temperature, and improve the accuracy of the overall temperature feedback end.
