Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power and lighting power distribution control box. Background Technology

[0002] As crucial equipment for power distribution, control, and protection, power distribution control cabinets primarily function to distribute electrical energy, protect electrical appliances, and control electrical energy. Based on their structure, power distribution control cabinets are typically categorized into protective distribution cabinets, drawer-type distribution cabinets, and power and lighting distribution control boxes. Power and lighting distribution control boxes are usually enclosed structures and are widely used in industrial and mining enterprises for on-site power distribution and transmission systems. To ensure the safety of power and lighting distribution control boxes, it is generally stipulated that there should be no obstructions within 0.8m-1.2m in front of the distribution box.

[0003] Although existing power lighting distribution control boxes have safety warning signs on their surfaces, flammable and explosive obstructions are still unavoidable in front of them when used in public areas. In order to prevent electrical leakage and fire accidents from power lighting distribution control boxes, and to ensure the safety of their use, we propose a power lighting distribution control box that can avoid the impact of the installation environment on safety. Utility Model Content

[0004] The purpose of this utility model is to provide a power lighting distribution control box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power lighting distribution control box, comprising a box body and power lighting distribution components installed inside the box body. The box body is a wall-mounted distribution box, with multiple air inlets through the surface of the box body, allowing ventilation of the box body's interior. Two opposing inner walls of the box body are movably connected by slide rails to multi-layered device drawers, allowing for the layered installation of power lighting distribution structures of different sizes or functions. An exhaust channel runs through the interior of the box body, guiding gas out of the box body. One end of the exhaust channel is coaxially connected to a connecting channel, and one end of the connecting channel is connected to an exhaust fan. The output end of the exhaust fan is connected to an air chamber via a bearing, and one end of the air chamber is movably connected to a Z-shaped tube via a rolling bearing. The high-speed airflow discharged from the air chamber can circulate through the Z-shaped tube. The airflow impacts the inner wall of the Z-tube, applying a thrust to the inner wall and continuously pushing the Z-tube to rotate vertically. The gas exiting from the Z-tube opening and through the exhaust nozzle can be sprayed onto obstacles in front of the box. A pressure sensor detects the airflow reflected from the obstacle surface. Based on the intensity of the reflected airflow and the flow rate of the gas exiting the exhaust nozzle, the pressure sensor determines the distance of the obstacle from the front of the box. If the distance is determined to be less than the safe distance, an alarm signal is transmitted to the maintenance personnel terminal via an alarm signal transmitting antenna. This allows maintenance personnel to promptly handle the obstacles in front of the power distribution control box and prevents them from affecting the safe operation of the power distribution control box. A pressure sensor is fixed to the opening of the Z-tube via a connecting plate. An exhaust nozzle is opened on one side of the connecting plate, facing the opening of the Z-tube. An alarm signal transmitting antenna is installed on the surface of the box.

[0006] As a further embodiment of this utility model: the power lighting distribution assembly includes a safety switch group, a voltmeter, an ammeter, and an operating handle. The safety switch group and the operating handle are fixedly installed in the cavity formed inside the box. The voltmeter and the ammeter are fixed on one side wall of the box. The power lighting distribution assembly can detect electrical parameters such as voltage and current in the power distribution control box. At the same time, it can control the power supply to be switched on and off through the safety switch group.

[0007] As a further embodiment of this utility model: the inner wall of the component drawer is formed with a perforated rigid plate, and elongated grooves for matching slide rails are respectively opened on both sides of the component drawer. A latch is installed on one side of the component drawer, and a fixing plate for matching the latch is welded to one side of the box. A locking tongue for matching the latch is connected to the inner wall of the fixing plate. By cooperating with a single matching latch and locking tongue, a single component drawer can be locked, which facilitates the layered maintenance of electrical components in the power distribution control box.

[0008] As a further embodiment of this utility model: the exhaust channel runs through the gap formed between two adjacent device drawers, the connecting channel is an L-shaped hollow cylindrical tube, the exhaust channels are arranged linearly at equal intervals, and multiple exhaust channels and connecting channels can evenly discharge the gas in the box into the interior of the vacuum pump.

[0009] As a further embodiment of this utility model: the input end of the air extractor is electrically connected to an external power source, and a positioning plate is fixed on one side of the air extractor. The positioning plate is bolted to the side wall of the housing, and the positioning plate can fix the air extractor to the side of the housing.

[0010] As a further aspect of this invention: the Z-tube has a Z-shaped airflow channel inside, and the air pressure sensor is a Honeywell BPS-6L-001 sensor. When the high-speed airflow impacts the inner wall of the Z-shaped airflow channel, it can drive the Z-tube to rotate around the center line of the rolling bearing.

[0011] As a further aspect of this invention: the internal cavity of the air chamber includes a conical cavity, and the constricted part of the air chamber can enhance the pressure of the gas entering the Z-tube and increase the thrust of the airflow impacting the inner wall of the Z-tube.

[0012] As a further embodiment of this utility model: a wall-mounted plate and screw holes are welded to the back of the box, and a maintenance plate is installed on one side of the box. The area of ​​the maintenance plate is not less than 90% of the side area of ​​the box. Opening the maintenance plate allows for a comprehensive inspection of the interior of the power distribution control box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a pressure sensor to sense the airflow reflected from the surface of an obstacle. The pressure sensor determines the distance between the obstacle and the front of the box based on the intensity of the reflected airflow and the flow rate of the gas discharged from the exhaust nozzle. If the distance is less than the safe distance, an alarm signal is transmitted to the maintenance personnel terminal via an alarm signal transmitting antenna so as to promptly notify the maintenance personnel to deal with the obstacle in front of the power distribution control box and avoid the obstacle affecting the safe operation of the power distribution control box.

[0015] 2. This utility model guides the gas inside the box to the exhaust fan through the exhaust channel and connecting channel. The exhaust fan can quickly discharge the high-temperature gas inside the box. While detecting obstacles in front of the power distribution control box, it can also improve the heat dissipation effect inside the box. The array of exhaust channels can improve the uniformity of heat dissipation inside the box. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a power lighting distribution control box, including a box body 1 and a power lighting distribution component installed inside the box body 1. The box body 1 is a wall-mounted distribution box, and an air inlet 19 is provided through the surface of the box body 1. Multiple air inlets 19 are provided to allow ventilation of the interior of the box body 1. The power lighting distribution component includes a safety switch group, a voltmeter, an ammeter, and an operating handle. The safety switch group and the operating handle are fixedly installed in the cavity formed inside the box body 1. The voltmeter and ammeter are fixed on one side wall of the box body 1. The power lighting distribution component can detect electrical parameters such as voltage and current inside the distribution control box, and at the same time, can control the power supply through the safety switch group.

[0023] Two opposing inner walls of the housing 1 are movably connected to multi-layer device drawers 4 via slide rails 2. The multi-layered device drawers 4 can accommodate power lighting distribution structures of different sizes or functions. An exhaust channel 6 runs through the interior of the housing 1 to drain the gas inside the housing 1. One end of the exhaust channel 6 is coaxially connected to a connecting channel 7. One end of the connecting channel 7 is connected to an air extractor 8. The output end of the air extractor 8 is connected to an air chamber 9 via a bearing. One end of the air chamber 9 is movably connected to a Z-shaped tube 11 via a rolling bearing 10. The input end of the air extractor 8 is electrically connected to an external power source. A positioning plate 81 is fixed to one side of the air extractor 8. The positioning plate 81 is bolted to the side wall of the housing 1. The positioning plate 81 can fix the air extractor 8 to the side of the housing 1.

[0024] The high-speed airflow discharged from the air chamber 9 impacts the inner wall of the Z-tube 11, thereby applying the thrust generated by the airflow to the inner wall of the Z-tube 11 and continuously pushing the Z-tube 11 to rotate in the vertical direction. The gas discharged from the opening of the Z-tube 11 and through the exhaust nozzle 14 can be sprayed onto the obstacle in front of the box 1. The air pressure sensor 13 senses the airflow reflected from the surface of the obstacle. Based on the intensity of the reflected airflow and the flow rate of the gas discharged from the exhaust nozzle 14, the air pressure sensor 13 determines the distance of the obstacle from the front of the box. If the distance is determined to be less than the safe distance, an alarm signal is transmitted to the maintenance personnel terminal through the alarm signal transmitting antenna 15 so as to promptly notify the maintenance personnel to deal with the obstacle in front of the power distribution control box 1 and avoid the obstacle affecting the safe operation of the power distribution control box. The air pressure sensor 13 is fixed at the opening of the Z-tube 11 through the connecting plate 12. An exhaust nozzle 14 is opened on one side of the connecting plate 12, facing the opening of the Z-tube 11. The alarm signal transmitting antenna 15 is installed on the surface of the box 1.

[0025] Preferred, such as Figure 1 As shown, the inner wall of the device drawer 4 is formed with a perforated hard plate. The two sides of the device drawer 4 are respectively provided with elongated grooves 3 that are adapted to the slide rail 2. A latch 5 is installed on one side of the device drawer 4. A fixing plate 401 adapted to the latch 5 is welded to one side of the box body 1. The inner wall of the fixing plate 401 is connected to the latch tongue adapted to the latch 5. By cooperating with a single adapted latch 5 and latch tongue, the device drawer 4 can be locked, which facilitates the layered maintenance of electrical components in the power distribution control box.

[0026] Preferred, such as Figure 1 As shown, the exhaust channel 6 passes through the gap formed between two adjacent device drawers 4, and the connecting channel 7 is an L-shaped hollow cylindrical tube. The exhaust channels 6 are arranged linearly at equal intervals. Multiple exhaust channels 6 and connecting channels 7 can evenly discharge the gas in the box 1 into the interior of the vacuum pump 8.

[0027] Preferred, such as Figure 1As shown, the Z-shaped airflow channel is formed inside the Z-tube 11. The air pressure sensor 13 is a Honeywell BPS-6L-001 sensor. When the high-speed airflow impacts the inner wall of the Z-shaped airflow channel, it can drive the Z-tube 11 to rotate around the center line of the rolling bearing 10.

[0028] Preferred, such as Figure 2 As shown, the internal cavity of the air chamber 9 includes a conical cavity. The constricted part of the air chamber 9 can enhance the pressure of the gas entering the Z-tube 11 and increase the thrust of the airflow impacting the inner wall of the Z-tube 11.

[0029] Preferred, such as Figure 4 As shown, a wall-mounted plate 16 and screw hole plate 17 are welded to the back of the box 1. A maintenance plate 18 is installed on one side of the box 1. The area of ​​the maintenance plate 18 is not less than 90% of the side area of ​​the box 1. Opening the maintenance plate 18 allows for a comprehensive inspection of the interior of the power distribution control box.

[0030] Working principle: During use, the housing 1 is fixed to the mounting wall using bolts with matching screw holes 17. Simultaneously, the housing 1 is wall-mounted using the wall-mounting plate 16. The power and lighting distribution components inside the housing 1 are fixedly connected by using a multi-layer component drawer 4 mounted on the side, allowing for layered maintenance of the power and lighting distribution components and improving the convenience of control box maintenance. When detecting obstacles directly in front of the control box, the vacuum pump 8 is activated. The vacuum pump 8 transports the gas inside the housing 1 through the exhaust channel 6 and connecting channel 7 to the air chamber 9. When the gas is discharged through the air chamber 9 into the Z-tube 11, the conical cavity at one end of the air chamber 9 increases the pressure of the gas entering the Z-tube 11. On the one hand, the inner diameter of the Z-tube 11 is smaller than that of the air chamber 9, which helps to increase the pressure of the gas entering the Z-tube 11. When the gas enters the Z-tube 11, the impact force of the gas on the inner wall of the Z-tube 11 pushes the Z-tube 11 to rotate around the center line of the rolling bearing 10. The air pressure sensor 13 installed at one end of the Z-tube 11 detects the intensity of the airflow reflected by the obstacle. The air pressure sensor 13 judges the distance of the obstacle from the front of the box 1 based on the intensity of the reflected airflow and the flow rate of the gas discharged from the exhaust nozzle 14. If the distance is less than the safe distance, an alarm signal is transmitted to the maintenance personnel terminal through the alarm signal transmitting antenna 15 so as to promptly notify the maintenance personnel to deal with the obstacle in front of the power distribution control box 1.
