Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power distribution cabinet technology, and specifically relates to a device for assisting in the monitoring and maintenance of low-voltage power distribution cabinets. Background Technology
[0002] In modern power systems, low-voltage switchgear, as a key device for power distribution and control, is widely used in various industrial sites, commercial buildings, and residential communities. Its stable operation is crucial for ensuring the reliability and security of power supply. However, existing low-voltage switchgear has many problems in monitoring and maintenance, especially in the field of remote monitoring, where it faces severe challenges.
[0003] Most power distribution cabinets are not equipped with monitoring devices, which makes the monitoring of equipment operation status highly dependent on manual inspection mode. Maintenance personnel need to conduct item-by-item inspections of the power distribution cabinets according to fixed cycles. In addition, during long-term operation, the internal temperature of the power distribution cabinets may rise. However, existing power distribution cabinets generally lack real-time temperature monitoring and maintenance mechanisms. When the internal temperature of the equipment exceeds the safety threshold, cooling measures cannot be triggered in time, which may even lead to fire accidents in severe cases.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a device for assisting in the monitoring and maintenance of low-voltage distribution cabinets, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a device for assisting in the monitoring and maintenance of low-voltage distribution cabinets, including a distribution cabinet body with multiple heat dissipation holes symmetrically opened on the distribution cabinet body. The device is characterized in that: a controller, a communication module and a temperature and humidity sensor are installed in the internal cavity of the distribution cabinet body; a connecting plate is installed on the top of the distribution cabinet body; cooling fans are symmetrically installed on the connecting plate; a lifting mechanism is installed on the connecting plate; a monitoring device is installed on the lifting mechanism; and square holes are opened on the connecting plate.
[0008] Furthermore, a bracket is installed on the top of the power distribution cabinet body, a solar panel is installed on the top of the bracket, and a storage battery is installed at the bottom of the solar panel.
[0009] Furthermore, a cabinet door is installed on the front of the power distribution cabinet body.
[0010] Furthermore, the lifting mechanism includes a mounting base, which is mounted on the connecting plate, and connecting frames are symmetrically mounted at both ends of the mounting base.
[0011] Furthermore, a fixing plate is symmetrically installed between the two connecting frames, and a guide rail is installed on each of the two connecting frames.
[0012] Furthermore, sliders are installed on both guide rails, and mounting plates are installed on the front of the two sliders. The monitoring device is fixedly installed on the bottom of the mounting plates.
[0013] Furthermore, a servo motor is mounted on one of the two fixed plates, and a lead screw is mounted on the output end of the servo motor.
[0014] Furthermore, the other end of the lead screw is rotatably mounted on another of the fixed plates, and the lead screw is threadedly mounted to the mounting plate.
[0015] This utility model has the following beneficial effects:
[0016] This invention collects temperature and humidity information inside the power distribution cabinet from temperature and humidity sensors via a controller. This data is then remotely transmitted to the monitoring center and the terminal devices of maintenance personnel via a communication module. The monitoring equipment can monitor the inside of the power distribution cabinet and its surrounding environment. Maintenance personnel can understand the operating status of the power distribution cabinet in real time without going to the site, thus achieving remote monitoring. This solves the problem of existing power distribution cabinets relying on manual inspections and improves maintenance efficiency and timeliness.
[0017] This invention uses a temperature and humidity sensor to monitor the temperature and humidity inside the distribution cabinet in real time. When the temperature exceeds a set safety threshold, the controller receives a signal from the temperature and humidity sensor and activates two cooling fans via a control circuit. The cooling fans are mounted on a connecting plate and are symmetrically distributed to blow cool air from outside the distribution cabinet into the cabinet body. At the same time, hot air inside the cabinet is discharged through multiple symmetrically opened heat dissipation holes on the cabinet body, forming airflow. This reduces the temperature inside the distribution cabinet body, preventing the normal operation of electrical equipment from being affected by excessive temperature and avoiding fire accidents.
[0018] With this invention, maintenance personnel can send instructions to the communication module inside the power distribution cabinet through the management system at the monitoring center. The communication module then transmits the instructions to the controller, which generates a drive signal and sends it to the lifting mechanism. Subsequently, the monitoring equipment can enter the power distribution cabinet through the start of the lifting mechanism to monitor the operation process in real time.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0031] Please see Figures 1-6 As shown, this utility model is a device for assisting in the monitoring and maintenance of low-voltage distribution cabinets. It includes a distribution cabinet body 1 with multiple heat dissipation holes 2 symmetrically opened on it. The device is characterized in that: a controller 3, a communication module 4 and a temperature and humidity sensor 5 are installed in the inner cavity of the distribution cabinet body 1; a connecting plate 6 is installed on the top of the distribution cabinet body 1; cooling fans 7 are symmetrically installed on the connecting plate 6; a lifting mechanism 8 is installed on the connecting plate 6; and a monitoring device 9 is installed on the lifting mechanism 8.
[0032] A bracket 10 is installed on the top of the power distribution cabinet body 1, a solar panel 11 is installed on the top of the bracket 10, and a storage battery 12 is installed at the bottom of the solar panel 11.
[0033] The controller 3 uses an S7-200 SMART and is electrically connected to the temperature and humidity sensor 5 (PMC-2603), the cooling fan 7 (20060), and the communication module 4 (USR-C322).
[0034] Temperature and humidity sensor 5 monitors the temperature and humidity information inside the distribution cabinet body 1 in real time. When the temperature exceeds the set safety threshold, controller 3 receives the signal from temperature and humidity sensor 5 and starts two cooling fans 7 through the control circuit. The cooling fans 7 are installed on the connecting plate 6 and are symmetrically distributed to blow the cold air outside the distribution cabinet body 1 into the distribution cabinet body 1. At the same time, the hot air inside is discharged through multiple heat dissipation holes 2 symmetrically opened on the distribution cabinet body 1, forming air flow, thereby reducing the temperature inside the distribution cabinet body 1, preventing the normal operation of electrical equipment from being affected by excessive temperature, and avoiding fire accidents. Controller 3 collects the temperature and humidity information inside the distribution cabinet body 1 detected by temperature and humidity sensor 5 and transmits this data remotely to the monitoring center and the terminal equipment of operation and maintenance personnel through communication module 4. In this way, operation and maintenance personnel can understand the operating status of the distribution cabinet in real time without going to the site, realize remote monitoring, solve the problem of existing distribution cabinets relying on manual inspection, and improve operation and maintenance efficiency and timeliness.
[0035] When staff perform inspection or maintenance work inside the power distribution cabinet 1, the maintenance personnel can send instructions to the communication module 4 inside the power distribution cabinet 1 through the management system in the monitoring center. The communication module 4 then transmits the instructions to the controller 3, which generates a drive signal and sends it to the lifting mechanism 8. Subsequently, the monitoring equipment 9 enters the power distribution cabinet 1 through the start of the lifting mechanism 8 to monitor the operation process in real time. The maintenance personnel can also control the lifting mechanism 8 to lift the monitoring equipment 9 to the outside of the power distribution cabinet 1, so that the monitoring equipment 9 can monitor the power distribution cabinet 1 and its surrounding environment, such as whether any personnel are approaching or whether there are any external environmental factors that may affect the power distribution cabinet.
[0036] All batteries 12 are electrically connected to controller 3, temperature and humidity sensor 5, cooling fan 7, communication module 4 and monitoring equipment 9;
[0037] The solar panel 11 on the top of the bracket 10 converts solar energy into electrical energy under sunlight and stores it in the battery 12. This provides power to the monitoring equipment 9, temperature and humidity sensor 5, communication module 4, controller 3 and cooling fan 7 in the power distribution cabinet 1, ensuring the continuous operation of the equipment.
[0038] In one embodiment, the connecting plate 6 has a square hole 601 and a cabinet door 101 is installed at one end of the power distribution cabinet body 1.
[0039] The lifting mechanism 8 includes a mounting base 801, which is mounted on the connecting plate 6. Connecting brackets 802 are symmetrically mounted at both ends of the mounting base 801.
[0040] A fixing plate 803 is symmetrically installed between the two connecting frames 802, and a guide rail 804 is installed on each of the two connecting frames 802.
[0041] Slider 805 is installed on both guide rails 804, and mounting plate 806 is installed on the front of the two sliders 805. The monitoring device 9 is fixedly installed on the bottom of the mounting plate 806.
[0042] A servo motor 807 is mounted on one of the two fixed plates 803, and a lead screw 808 is mounted on the output end of the servo motor 807.
[0043] The other end of the lead screw 808 is rotatably mounted on another fixed plate 803, and the lead screw 808 is threadedly mounted to the mounting plate 806.
[0044] Working principle: The square hole 601 on the connecting plate 6 provides a channel for the lifting and lowering of the monitoring equipment 9. The cabinet door 101 is used to open or close the power distribution cabinet body 1. The mounting base 801 is fixed on the connecting plate 6, and the connecting brackets 802 at both ends are symmetrically distributed to form a support frame. The two connecting brackets 802 are fixedly connected by a fixing plate 803. The fixing plate 803 is equipped with a guide rail 804. The slider 805 on the guide rail 804 can slide up and down along the guide rail 804. The slider 805 is connected to the monitoring equipment 9 through the mounting plate 806. When the control... When device 3 receives the lifting command from the monitoring center, it sends an electrical signal to servo motor 807. Servo motor 807 starts to rotate forward or in reverse according to the signal. Servo motor 807 drives lead screw 808 to rotate. If servo motor 807 drives lead screw 808 to rotate forward, mounting plate 806 moves downward along guide rail 804, driving monitoring device 9 from outside the power distribution cabinet body 1 into the interior through square hole 601. If servo motor 807 drives lead screw 808 in reverse, mounting plate 806 moves upward along guide rail 804, and monitoring device 9 rises from inside the cabinet to the outside.
[0045] When staff open cabinet door 101 to prepare for maintenance, the monitoring center can send a descent command. Servo motor 807 rotates forward, driving lead screw 808. Mounting plate 806 drives monitoring equipment 9 to descend along guide rail 804 through square hole 601 into the power distribution cabinet body 1, recording the operation in real time and transmitting it back. During routine inspections, the monitoring center can send an ascent command. Servo motor 807 rotates in reverse, and lead screw 808 drives monitoring equipment 9 to rise to the outside of power distribution cabinet body 1, providing video monitoring of the surrounding environment outside power distribution cabinet body 1.
