An intelligent indoor power distribution cabinet facilitating leakage alarm

Abstract

The present invention discloses an intelligent indoor power distribution cabinet facilitating leakage alarm, belonging to the field of power distribution cabinets; it includes a power distribution cabinet and an inverted V-shaped plate. On both sides of the inner wall of the power distribution cabinet, there are directional diversion mechanisms used in cooperation with the inverted V-shaped plate, and on both sides of the outer shell, there are warning mechanisms used in cooperation with the directional diversion mechanisms; when this application is in use, since the surface of the groove is sprayed with a fluorosilicon nano-coating, which has superhydrophobic properties, the condensed water quickly shrinks into a spherical shape, and under the action of the thrust gradient generated by the structural asymmetry, it automatically slides to the lower part and finally converges on the receiving plate at the end of the inverted V-shaped plate, and is introduced into the collection frame through the capillary drainage tube. When the capillary drainage tube is blocked or the drainage is overloaded, the water level in the collection frame exceeds the water level threshold, and the accumulated amount of condensed water directly touches and activates the alarm, avoiding the signal drift problem of traditional electronic sensors in high humidity environments and realizing the pre-warning of leakage risks.

Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and more specifically, to an intelligent indoor distribution cabinet facilitating leakage alarm. Background Art

[0002] As a key device for power distribution, the operation safety of an intelligent indoor distribution cabinet is directly related to the stability of the power consumption system. In actual use, the internal part of the distribution cabinet often has a leakage risk due to factors such as fluctuating environmental humidity, temperature change, or dust accumulation. For example, in a high-humidity environment with a large temperature difference between day and night, condensed water is likely to form on the surface of the metal components inside the cabinet, resulting in a decline in insulation performance. If such condensed water accumulates between the live bodies, it may trigger flashover or even leakage accidents; in scenarios with severe dust pollution such as chemical industry and mining, the combination of conductive dust and moisture may form a local conductive path, further exacerbating the leakage hazard. In addition, problems such as aging of the cable insulation layer and loosening of the connectors during long-term operation will also induce leakage accidents.

[0003] In the prior art, traditional leakage alarm technologies rely on electronic sensors (such as residual current transformers) to monitor current anomalies. However, this detection method has a high dependence on the sensor accuracy and environmental stability and is vulnerable to interference under complex working conditions. For example, a high-humidity environment may cause signal drift of the sensor, and the attachment of conductive dust may obscure the detection signal, resulting in false alarms or missed alarms, and it is unable to trigger early warning at the initial stage of condensed water accumulation. In addition, the existing distribution cabinets lack an active diversion mechanism for condensed water, resulting in the accumulated water directly dripping onto the electrical components, exacerbating the leakage risk.

[0018] Compared with the prior art, the above technical solutions provided by the present invention have at least the following beneficial effects:

[0019] (1) In this solution, by setting up an inverted V-shaped plate, a directional flow guiding mechanism, and an early warning mechanism, since the groove surface is sprayed with a fluorosilicon nano-coating, which has superhydrophobic properties, the condensed water quickly shrinks into a spherical shape and, under the action of the thrust gradient generated by the structural asymmetry, automatically slides to the lower part and finally converges on the receiving plate at the end of the inverted V-shaped plate. The receiving plate is designed with an inclined angle to guide the water droplets to roll along its groove and is introduced into the collection box through a capillary drainage tube. When the capillary drainage tube is blocked or the drainage is overloaded, the water level in the collection box exceeds the water level threshold, and the accumulated amount of condensed water directly touches the early warning mechanism, triggering the alarm, avoiding the signal drift problem of traditional electronic sensors in high-humidity environments, and realizing the pre-warning of leakage risks.

[0020] (2) By setting up an anti-siphon mechanism, the cooperation of an L-shaped connecting pipe and an inverted U-shaped pipe is used to block the siphon effect. Among them, the vent hole at the top of the bend of the inverted U-shaped pipe is covered with a PTFE hydrophobic film, which not only balances the air pressure inside and outside the pipeline but also completely blocks the reverse penetration of external water vapor. When the condensed water is discharged through the L-shaped connecting pipe, the water flow impacts the impeller to drive the rotating rod to rotate, driving the nylon brush to periodically scrape the discharge hole of the sealing cover, effectively solving the problem that traditional straight-through drain pipes are easily blocked by flocs.

[0021] (3) By setting up a sandwich layer and a wind guiding mechanism, when the temperature inside the cabinet exceeds 28 °C, the temperature sensor triggers the servo motor to rotate forward, driving the lead screw to rotate clockwise, driving the threaded seat to move upward, and turning the wind guiding plate outwards to 45° through the support plate, expanding the cross-sectional area of the ventilation slot and accelerating the influx of external cold air; at the same time, the paraffin microcapsules in the sandwich layer melt and absorb heat, delaying the temperature rise rate. When the ambient temperature at night drops below 22 °C, the servo motor rotates in reverse to retract the wind guiding plate to 15°, narrowing the air duct, and cooperating with the release of latent heat during the solidification of paraffin to control the temperature fluctuation inside the cabinet within the range of ±2 °C, reducing the generation of condensed water.

[0041] like Figures 1 to 8 As shown, an embodiment of the present invention provides an intelligent indoor power distribution cabinet that is convenient for leakage alarm, including a power distribution cabinet 1, with the side of the power distribution cabinet 1 with a cabinet door as the front side of the entire device; both sides of the outer surface of the power distribution cabinet 1 are inlaid with porous ceramic plates 2, an outer shell 3 is provided on the outer side of the power distribution cabinet 1, a ceiling 4 is fixedly connected to the top of the outer shell 3, an interlayer 5 is fixedly connected between the outer shell 3 and the porous ceramic plate 2, and the interior of the interlayer 5 is filled with a phase change material; an inverted V-shaped plate 6 is fixedly connected to the top of the power distribution cabinet 1, and directional guide mechanisms 7 used in conjunction with the inverted V-shaped plate 6 are provided on both sides of the inner wall of the power distribution cabinet 1, and early warning mechanisms 9 used in conjunction with the directional guide mechanisms 7 are provided on both sides of the outer shell 3;

[0042] The directional flow guide mechanism 7 includes a collection frame 71 fixedly connected to both sides of the inner wall of the power distribution cabinet 1, a receiving plate 72 is provided at the end of the bottom of the inverted V-shaped plate 6, a capillary drainage tube 73 fixedly connected to the collection frame 71 is provided at the flow guide end of the receiving plate 72, and an anti-siphon mechanism 8 is provided at the bottom of the collection frame 71. The anti-siphon mechanism 8 includes an inverted U-shaped tube 81, and a flow tube 75 is commonly connected between the capillary drainage tube 73 and the inverted U-shaped tube 81;

[0043] Among them, the early warning mechanism 9 includes a limiting tube 92 fixedly connected to the outside of the outer shell 3, a shunt tube 91 connected to the assembly frame 71 is arranged on one side of the bottom of the limiting tube 92, an alarm component is arranged on the top of the limiting tube 92, and a resistance component for opening the alarm component is arranged inside the limiting tube 92.

[0044] like Figure 1 , Figure 4 , Figure 6 As shown, the early warning mechanism 9 also includes a clamping plate 93 fixedly connected to both sides of the inner wall of the limiting tube 92, and a support plate is fixedly connected to the bottom of the clamping plate 93; the interference component includes a slider 94 slidably connected to the inside of the limiting tube 92, and grooves matching the clamping plate 93 are provided on both sides of the slider 94, and an interference rod 95 is fixedly connected to the top of the slider 94, and a circular groove is provided in the middle of the top of the limiting tube 92 to facilitate the extension and contraction of the interference rod 95.

[0045] like Figure 4 , Figure 6As shown, the alarm component includes a vertical rod 96 fixedly connected to the top of the limit pipe 92. The top of the vertical rod 96 is fixedly connected with an alarm 97, and an induction module is arranged at the bottom of the alarm 97. A baffle 98 is slidably connected to the outer circumferential surface of the vertical rod 96. An induction block 99 that is used in cooperation with the induction module is fixedly connected to the upper surface of the baffle 98 to control the activation of the alarm 97.

[0046] As Figure 2 , Figure 3 , Figure 4 As shown, the directional diversion mechanism 7 further includes an arc-shaped partition 74 fixedly connected to the middle inside the collection box 71. A water level port 76 is opened on one side of the top end of the outer surface of the collection box 71, and the water level port 76 is fixedly communicated with the shunt pipe 91 to facilitate liquid diversion.

[0047] As Figure 2 , Figure 3 , Figure 4 As shown, micron-level grooves arranged linearly are opened at the bottom of the inverted V-shaped plate 6. The inside of the grooves of the inverted V-shaped plate 6 has an asymmetric cross-section and is coated with a hydrophobic coating, so that water droplets can remain spherical under the action of the hydrophobic coating, and the water droplets roll along the grooves of the inverted V-shaped plate 6 towards the two side receiving plates 72.

[0048] As Figure 2 , Figure 3 , Figure 4 As shown, the capillary drainage tube 73 is a transparent quartz glass tube, and its inner wall is hydrophilically treated, and its outer wall is wrapped with a heat-insulating silica gel layer. One end of the capillary drainage tube 73 is fixedly communicated with the bottom of the receiving plate 72 to facilitate the flow of water droplets.

[0049] In order to solve the problem that the existing leakage alarm technology mainly relies on electronic sensor detection means, such as residual current transformer and insulation resistance monitoring device, the sound and light alarm is triggered and the fault circuit is cut off by monitoring the loop current imbalance or insulation state, but these methods have high requirements on sensor accuracy and environmental stability, and are easily disturbed under complex working conditions (such as high humidity or conductive dust), resulting in false alarms or missed alarms. The above technical solution is now adopted to solve the problem. The above technical solution is mainly composed of an inverted V-shaped plate 6, a directional guide mechanism 7, an anti-siphon mechanism 8, and an early warning mechanism 9. When the distribution cabinet 1 works at night, due to the large temperature difference between day and night, the temperature in the cabinet is lower than the dew point, and the water vapor in the air condenses into small water droplets on the inner wall of the cabinet top. At this time, the fluorosilicone nano-coating sprayed on the groove surface of the inverted V-shaped plate 6 plays a super-hydrophobic role, so that the water droplets cannot spread into a water film, but quickly shrink into a sphere (similar to the lotus leaf effect). After these spherical water droplets randomly fall into the groove, they are physically restricted by the vertical walls on both sides of the groove and can only move along the length of the groove. At the same time, the interior of the groove adopts an asymmetric cross-section design - one side has a steep slope (about 60°) and the other side has a gentle slope (about 30°). The thrust gradient generated by the structural asymmetry drives the water droplets to automatically slide to a lower place under the action of gravity, and finally converge on the receiving plate 72 at the end of the inverted V-shaped plate 6. The water droplets then continue to roll along the grooves of the receiving plate 72, and enter the collection frame 71 from the capillary drainage tube 73, completing the directional diversion of the water droplets, preventing the condensed water from being directly spread on the inner top of the distribution cabinet 1, and falling directly between the charged bodies due to gravity, causing flashover, thereby causing leakage; and the water droplets entering the collection frame 71 pass through the circulation tube 75 directly into the inverted U-shaped tube 81, and are discharged, thereby condensing the water. However, when the capillary drainage tube 73 is blocked or the drainage is overloaded, that is, when the water droplets enter the collection frame 71 and are higher than the water level port 76 The condensed water flows directly out of the water level port 76 and flows into the limit pipe 92 through the shunt pipe 91. As the water level continues to rise, the slider 94 moves upward along the guide of the card plate 93, and the resistance rod 95 moves upward synchronously, extending from the circular notch, and lifts the baffle 98, so that the baffle 98 rises linearly under the limiting action of the vertical rod 96, and then the induction block 99 touches the induction module at the bottom of the alarm 97, so that the alarm 97 sounds and performs a leakage warning operation, reminding the staff to check the internal situation of the power distribution cabinet in time. During the above operation process, the alarm is directly triggered by the amount of condensed water accumulation, and a warning is issued before leakage occurs; at the same time, the false alarm of the electronic sensor under high humidity is avoided.

[0050] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the anti-siphon mechanism 8 further includes an L-shaped connecting pipe 82 fixedly connected to the bottom of the inverted U-shaped pipe 81. An fixing plate 84 fixedly connected to the power distribution cabinet 1 is arranged on the outer circumferential surface of the inverted U-shaped pipe 81. Anti-blocking components 83 are arranged at the drainage ends of the L-shaped connecting pipes 82. The anti-blocking component 83 includes a sealing cover 831 sleeved on the outlet end of the L-shaped connecting pipe 82. Drainage holes are formed in the inner part of the sealing cover 831 in a surrounding manner. An L-shaped clamping seat 832 is fixedly connected to the inner part of the sealing cover 831. A rotating rod 833 is rotatably connected to the inner part of the L-shaped clamping seat 832. An impeller 834 is fixedly connected to the outer circumferential surface of the rotating rod 833. A brush 835 for cleaning the drainage holes is fixedly connected to one end of the rotating rod 833.

[0051] As Figure 2 , Figure 4 , Figure 5 shown, the phase change material is encapsulated in aluminum microcapsules and densely filled in the interlayer 5. A corrugated aluminum support net is arranged in the interlayer 5 to prevent the phase change material from settling. An air vent for balancing air pressure is arranged at the top of the bent part of the inverted U-shaped pipe 81, and a hydrophobic film is covered in the air vent to prevent external water vapor from invading.

[0052] The phase change material filled in the interlayer 5 is densely arranged after being encapsulated by aluminum microcapsules, and absorbs the heat generated by the temperature fluctuation in the cabinet through the solid-liquid phase change process, significantly reducing the generation amount of condensate water on the top of the cabinet. The corrugated aluminum support net arranged inside the interlayer 5 not only provides structural rigidity, but also prevents the material from settling due to long-term vibration through the multi-point contact between the corrugated curved surface and the microcapsules, ensuring the stability of the heat conduction efficiency.

[0053] During the process of guiding and discharging the condensate water, due to the arranged arc-shaped partition plate 74, the water flow is quickly concentrated and flows into the inverted U-shaped pipe 81 from the flow pipe 75, improving the drainage efficiency. The anti-siphon mechanism 8 realizes the blocking of the siphon effect through the cooperation of the L-shaped connecting pipe 82 and the inverted U-shaped pipe 81. Among them, the air vent arranged at the top of the bent part of the inverted U-shaped pipe 81 is covered with a PTFE hydrophobic film, which balances the air pressure inside and outside the pipeline and completely blocks the reverse penetration of external water vapor at the same time. At the same time, to prevent flying insects from entering the inverted U-shaped pipe 81 and affecting the discharge of condensate water, when the condensate water is discharged through the L-shaped connecting pipe 82, the water flow impacts the impeller 834, causing it to rotate, and drives the rotating rod 833 to rotate in the L-shaped clamping seat 832. Thus, the rotating rod 833 drives the brush 835 to rotate, causing the brush 835 to perform a circular motion inside the sealing cover 831, and using the brush 835 to clean and dredge the drainage holes of the sealing cover 831, ensuring the normal discharge of condensate water and reducing the accumulation of condensate water in the cabinet.

[0054] As Figure 7 , Figure 8As shown in the figure, ventilation grooves 10 are provided on both sides and the front side of the outer surface of the power distribution cabinet 1. A wind guiding mechanism 11 is arranged inside the ventilation groove 10 on the front side of the power distribution cabinet 1. The wind guiding mechanism 11 includes a fixed rod fixedly connected inside the ventilation groove 10. A wind guiding plate 117 is rotatably connected to the outer cylindrical surface of the fixed rod. A driving assembly for adjusting the opening and closing angle of the wind guiding plate 117 is arranged on the inner wall of the power distribution cabinet 1.

[0055] As Figure 7 , Figure 8 shown in the figure, the driving assembly includes a servo motor 111 fixedly connected to the bottom end of the front side of the inner wall of the power distribution cabinet 1. The output end of the servo motor 111 is fixedly connected with a lead screw 112. A limiting frame 113 fixedly connected to the power distribution cabinet 1 is arranged on one side of the outer cylindrical surface of the lead screw 112. A threaded seat 114 is threadedly connected to the outer cylindrical surface of the lead screw 112. The threaded seat 114 penetrates through the inside of the limiting frame 113 and is fixedly connected with a support seat 115. A support plate 116 is hinged inside the support seat 115. One end of the support plate 116 is hingedly connected to the bottom of the wind guiding plate 117. A temperature sensor 118 fixedly connected to the power distribution cabinet 1 is arranged on one side of the outer cylindrical surface of the servo motor 111.

[0056] During the use of the power distribution cabinet 1, due to the large temperature difference between day and night, the temperature inside the cabinet needs to be properly balanced to reduce the formation of condensed water. Therefore, when the temperature is high during the day, cold air enters the outer casing 3 through the ventilation holes on both sides of the ceiling 4 to form preliminary convective heat dissipation. As the temperature inside the cabinet rises, the aluminum microcapsules (phase change point 25°C) encapsulating paraffin in the interlayer 5 begin to melt and absorb heat, delaying the temperature rise rate inside the cabinet. At this time, the internal temperature of the power distribution cabinet 1 can be automatically measured by the temperature sensor 118. When the temperature sensor 118 detects that the temperature inside the cabinet exceeds the threshold of 28°C, it sends a signal to the control system and activates the servo motor 111 to rotate forward. Under the driving force of the servo motor 111, the lead screw 112 rotates clockwise, causing the threaded seat 114 to move upward along the track of the limit frame 113, and driving the support seat 115 to rise synchronously. Under the traction of the support seat 115, the support plate 116 expands outward, and then the air guide plate 117 flips outward, that is, the air flow ventilation duct is enlarged, and the external cold air rushes into the cabinet at an accelerated speed through the diversion slope of the air guide plate 117 to form forced convective heat dissipation. However, when the temperature drops at night, to ensure the internal temperature of the power distribution cabinet 1 and reduce heat dissipation, at this time, the paraffin in the interlayer 5 solidifies and releases latent heat to maintain the internal temperature of the power distribution cabinet 1. At the same time, the internal temperature of the power distribution cabinet 1 is automatically measured by the temperature sensor 118. When it is lower than a certain threshold, the servo motor 111 is activated again to rotate in reverse, causing the lead screw 112 to rotate counterclockwise, causing the threaded seat 114 to move downward along the track of the limit frame 113, and driving the support seat 115 to move downward synchronously. Under the traction of the support seat 115, the support plate 116 retracts inward, and then the air guide plate 117 retracts inward, that is, the air flow ventilation duct is reduced, reducing air circulation, and thus reducing the heat dissipation inside the power distribution cabinet 1.

[0057] When the present invention is in use, when the temperature inside the cabinet exceeds 28 °C, the temperature sensor 118 triggers the forward rotation of the servo motor 111, driving the lead screw 112 to rotate clockwise, driving the threaded seat 114 to move upward, turning the air guide plate 117 outward to 45° through the support plate 116, expanding the cross-sectional area of the ventilation slot 10, and accelerating the influx of external cold air; at the same time, the paraffin microcapsules in the interlayer 5 melt and absorb heat, delaying the temperature rise rate. When the ambient temperature at night drops below 22 °C, the servo motor 111 rotates reversely to retract the air guide plate 117 to 15°, narrowing the air duct, and cooperating with the latent heat released by the solidification of paraffin, controlling the temperature fluctuation inside the cabinet within the range of ±2 °C and reducing the generation of condensed water. And when the temperature at the top of the cabinet at night is lower than the dew point, the condensed water droplets shrink into spherical shapes in the super-hydrophobic grooves (sprayed with fluorosilicon nano-coatings) of the inverted V-shaped plate 6, and slide directionally along the grooves to the receiving plate 72 under the thrust of the asymmetric cross-section, and are introduced into the collection frame 71 through the capillary drainage tube 73, and finally discharged through the circulation tube 75 into the inverted U-shaped tube 81; and during the discharge process of the condensed water, the arc-shaped partition 74 accelerates the convergence of the water flow and improves the drainage efficiency. If the capillary drainage tube 73 is blocked and the water level in the collection frame 71 exceeds the limit, the condensed water is diverted to the limit tube 92 through the water level port 76, pushing the slider 94 upward, lifting the baffle 98 through the contact rod 95 to trigger the alarm 97 to issue a warning alarm; and during the drainage process, the water flow in the L-shaped connecting tube 82 impacts the impeller 834 to drive the brush 835 to rotate to clean the discharge hole, combined with the PTFE hydrophobic membrane ventilation hole at the top of the inverted U-shaped tube 81, synchronously blocking the siphon effect and the intrusion of external water vapor.
