Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and more particularly to an intelligent indoor power distribution cabinet which is convenient for electric leakage alarm. Background Art

[0002] As a key device for power distribution, the operational safety of intelligent indoor power distribution cabinets is directly related to the stability of the power consumption system. In actual use, the inside of the power distribution cabinet often causes leakage risks due to factors such as environmental humidity fluctuations, temperature changes or dust accumulation. For example, in a high-humidity environment with a large temperature difference between day and night, condensation water is easily formed on the surface of metal parts in the cabinet, resulting in a decrease in insulation performance. If such condensation water accumulates between charged bodies, it may cause flashover or even leakage accidents; and in scenes with severe dust pollution such as chemical and mining, conductive dust combined with moisture may form a local conductive path, further exacerbating the risk of leakage. In addition, problems such as aging of cable insulation and loose connectors under long-term operation can also induce leakage accidents.

[0003] In the prior art, traditional leakage alarm technology relies on electronic sensors (such as residual current transformers) to monitor current anomalies. However, this detection method is highly dependent on sensor accuracy and environmental stability, and is susceptible to interference under complex working conditions. For example, a high humidity environment may cause sensor signals to drift, and the adhesion of conductive dust may obscure the detection signal, causing false alarms or missed alarms, and it is impossible to trigger an early warning at the early stage of condensation water accumulation. In addition, the existing distribution cabinet lacks an active diversion mechanism for condensation water, causing accumulated water to drip directly onto electrical components, exacerbating the risk of leakage.

[0016] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) This scheme is provided with an inverted V-shaped plate, a directional guide mechanism, and an early warning mechanism. Since the groove surface is sprayed with a fluorosilicone nano-coating, it has super-hydrophobic properties, which causes the condensed water to quickly shrink into a spherical shape and automatically slide to a lower place under the action of the thrust gradient generated by the structural asymmetry, and finally converge 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 grooves and be 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 condensed water directly conflicts with the early warning mechanism, activating the alarm, thereby avoiding the signal drift problem of traditional electronic sensors in high humidity environments and realizing a pre-warning of leakage risks.

[0017] (2) By setting up an anti-siphon mechanism, the siphon effect is blocked by the cooperation of the L-shaped connecting pipe and the inverted U-shaped pipe. The air hole set at the top of the inverted U-shaped pipe is covered with a PTFE hydrophobic membrane, which can balance the air pressure inside and outside the pipe while completely blocking 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 clean the discharge hole of the sealing cover, effectively solving the problem that the traditional straight-through drain pipe is easily blocked by flocs.

[0018] (3) By setting up the interlayer and air guide mechanism, when the temperature inside the cabinet exceeds 28°C, the temperature sensor triggers the servo motor to rotate forward, drives the screw to rotate clockwise, drives the threaded seat to move upward, and turns the air guide plate outward to 45° through the support plate, expands the cross-sectional area of ​​the ventilation slot, and accelerates the influx of external cold air; at the same time, the paraffin microcapsules in the interlayer melt and absorb heat, slowing down the temperature rise rate. When the ambient temperature drops below 22°C at night, the servo motor reverses to retract the air guide plate inward to 15°, narrows the air duct, and cooperates with the solidification of paraffin to release latent heat, so as to control the temperature fluctuation in the cabinet within the range of ±2°C and reduce the generation of condensed water.

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; 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.

[0025] 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.

[0026] like Figure 4 , Figure 6 As shown, the alarm assembly includes a vertical rod 96 fixedly connected to the top of the limiting tube 92, an alarm 97 is fixedly connected to the top of the vertical rod 96, and a sensing module is provided at the bottom of the alarm 97; a baffle 98 is slidably connected to the outer circular surface of the vertical rod 96, and a sensing block 99 used in conjunction with the sensing module is fixedly connected to the upper surface of the baffle 98 to control the opening of the alarm 97.

[0027] like Figure 2 , Figure 3 , Figure 4As shown, the directional flow guide mechanism 7 also includes an arc-shaped partition plate 74 fixedly connected to the middle of the assembly frame 71, and a water level port 76 is opened on one side of the top of the outer surface of the assembly frame 71, and the water level port 76 is fixedly connected to the diversion pipe 91 to facilitate liquid diversion.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown, the bottom of the inverted V-shaped plate 6 is provided with linearly arranged micron-sized grooves, and the interior 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 maintain a spherical shape under the action of the hydrophobic coating, and roll along the grooves of the inverted V-shaped plate 6 toward the receiving plates 72 on both sides.

[0029] like Figure 2 , Figure 3 , Figure 4 As shown, the capillary drainage tube 73 is a transparent quartz glass tube, and the inner wall is hydrophilic treated and the outer wall is wrapped with a heat-insulating silica gel layer; one end of the capillary drainage tube 73 is fixedly connected to the bottom of the receiving plate 72 to facilitate the circulation of water droplets.

[0030] 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.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the anti-siphon mechanism 8 also includes an L-shaped connecting pipe 82 fixedly connected to the bottom of the inverted U-shaped pipe 81, the outer cylindrical surface of the inverted U-shaped pipe 81 is provided with a fixing plate 84 fixedly connected to the distribution cabinet 1, and the drainage end of the L-shaped connecting pipe 82 is provided with an anti-blocking component 83, and the anti-blocking component 83 includes a sealing cover 831 sleeved on the outlet end of the L-shaped connecting pipe 82, and the sealing cover 831 is surrounded by a discharge hole, the sealing cover 831 is fixedly connected to an L-shaped seat 832, and the L-shaped seat 832 is rotatably connected to a rotating rod 833, the outer cylindrical surface of the rotating rod 833 is fixedly connected to an impeller 834, and one end of the rotating rod 833 is fixedly connected to a brush 835 for cleaning the discharge hole.

[0032] like Figure 2 , Figure 4 , Figure 5 As shown, the phase change material is encapsulated in aluminum microcapsules and densely filled in the interlayer 5. A wavy aluminum support mesh is provided inside the interlayer 5 to prevent the phase change material from settling. An air hole for balancing the air pressure is provided at the top of the bend of the inverted U-shaped tube 81, and the air hole is covered with a hydrophobic film to prevent external water vapor from intruding.

[0033] The phase change material filled in the interlayer 5 is densely packed 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 amount of condensed water generated on the cabinet top. The wavy aluminum support mesh set inside the interlayer 5 not only provides structural rigidity, but also prevents the material from settling due to long-term vibration through multi-point contact between the wavy surface and the microcapsules, ensuring the stability of heat conduction efficiency.

[0034] In the process of diverting and discharging the condensed water, the water flow is quickly concentrated due to the arc-shaped partition 74, and flows from the circulation pipe 75 into the inverted U-shaped pipe 81, thereby improving the drainage efficiency; and 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 vents arranged at the top of the bend of the inverted U-shaped pipe 81 are covered with a PTFE hydrophobic membrane, which completely blocks the reverse penetration of external water vapor while balancing the air pressure inside and outside the pipeline. At the same time, in order to prevent flying insects from entering the inverted U-shaped pipe 81 and affecting the discharge of condensed water, when the condensed water is discharged through the L-shaped connecting pipe 82, the water flow impacts the impeller 834, causing it to rotate, and driving the rotating rod 833 to rotate in the L-shaped seat 832, so that the rotating rod 833 drives the brush 835 to rotate, so that the brush 835 makes a circular motion inside the sealing cover 831, and uses the brush 835 to clean and dredge the discharge hole of the sealing cover 831, so as to ensure the normal discharge of condensed water and reduce the accumulation of condensed water in the cabinet.

[0035] like Figure 7 , Figure 8As shown, ventilation slots 10 are provided on both sides and the front side of the outer surface of the distribution cabinet 1, and an air guide mechanism 11 is provided inside the ventilation slots 10 on the front side of the distribution cabinet 1. The air guide mechanism 11 includes a fixed rod fixedly connected to the inside of the ventilation slot 10, and an air guide plate 117 is rotatably connected to the outer circular surface of the fixed rod. The inner wall of the distribution cabinet 1 is provided with a driving component for adjusting the opening and closing angle of the air guide plate 117.

[0036] like Figure 7 , Figure 8 As shown, the drive assembly includes a servo motor 111 fixedly connected to the bottom end of the front side of the inner wall of the distribution cabinet 1, the output end of the servo motor 111 is fixedly connected to a screw rod 112, one side of the outer cylindrical surface of the screw rod 112 is provided with a limit frame 113 fixedly connected to the distribution cabinet 1, the outer cylindrical surface of the screw rod 112 is threadedly connected to a threaded seat 114, the threaded seat 114 passes through the interior of the limit frame 113 and is fixedly connected to a support seat 115, the interior of the support seat 115 is hinged with a support plate 116, one end of the support plate 116 is hingedly connected to the bottom of the air guide plate 117, and one side of the outer cylindrical surface of the servo motor 111 is provided with a temperature sensor 118 fixedly connected to the distribution cabinet 1.

[0037] During the use of the distribution cabinet 1, due to the high temperature during the day and at 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 shell 3 from the air holes on both sides of the ceiling 4, forming a preliminary convection heat dissipation; and 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, slowing down the temperature rise rate inside the cabinet. At this time, the internal temperature of the 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 value of 28°C, a signal is sent to the control system, and the servo motor 111 is turned on to make it rotate forward. Under the driving force of the servo motor 111, the screw rod 112 rotates clockwise, so that the threaded seat 114 moves upward along the trajectory of the limit frame 113, and drives the support seat 115 to rise synchronously. Under the traction force of the support seat 115, the support plate 116 is stretched outward, and then the air guide plate 117 is turned outward, that is, the air flow duct is expanded, and the external cold air is accelerated to flow into the cabinet through the guide slope of the air guide plate 117, forming forced convection heat dissipation. However, when the temperature drops at night, in order to ensure the internal temperature of the distribution cabinet 1 and reduce heat dissipation, the paraffin in the interlayer 5 solidifies and releases latent heat to maintain the internal temperature of the distribution cabinet 1. At the same time, the temperature sensor 118 is used to automatically measure the internal temperature of the distribution cabinet 1. When it is lower than a certain threshold, the servo motor 111 is turned on again to reverse it, so that the screw rod 112 rotates counterclockwise, so that the threaded seat 114 moves downward along the trajectory of the limit frame 113, and drives the support seat 115 to move downward synchronously. Under the traction force 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 duct is narrowed, the air circulation is reduced, and the heat dissipation inside the distribution cabinet 1 is reduced.

[0038] When the present invention is in use, when the temperature in the cabinet exceeds 28°C, the temperature sensor 118 triggers the servo motor 111 to rotate forward, drives the screw rod 112 to rotate clockwise, drives the threaded seat 114 to move upward, and turns the air guide plate 117 outward to 45° through the support plate 116, expands the cross-sectional area of ​​the ventilation slot 10, and accelerates the influx of external cold air; at the same time, the paraffin microcapsules in the interlayer 5 melt and absorb heat, slowing down the rate of temperature rise. When the ambient temperature at night drops below 22°C, the servo motor 111 reverses to retract the air guide plate 117 to 15°, shrinks the air duct, and cooperates with the solidification of paraffin to release latent heat, so as to control the temperature fluctuation in the cabinet within the range of ±2°C and reduce the generation of condensed water. When the temperature on the top of the cabinet is lower than the dew point at night, the condensed water droplets shrink into a spherical shape in the super-hydrophobic groove (sprayed with fluorine-silicon nano-coating) of the inverted V-shaped plate 6, slide down along the groove 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 enter the inverted U-shaped tube 81 through the circulation tube 75 for discharge; and in the process of condensed water discharge, the arc partition 74 accelerates the convergence of water flow and improves the drainage efficiency. If the capillary drainage tube 73 is blocked and the water level of 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 to move up, and the baffle 98 is lifted by the contact rod 95 to trigger the alarm 97 to sound a warning alarm; and in the drainage process, the water flow in the L-shaped connecting tube 82 impacts the impeller 834 to drive the brush 835 to rotate and clean the discharge hole, and combined with the PTFE hydrophobic membrane air permeable hole at the top of the inverted U-shaped tube 81, the siphon effect and external water vapor intrusion are blocked simultaneously.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
