Description

Technical Field

[0001] This invention relates to the field of low-voltage switchgear technology, and in particular to a stable and convenient intelligent low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear is equipment used to connect low-voltage cables. Power supply bureaus and substations typically use high-voltage switchgear, which then steps down the voltage via transformers before connecting to low-voltage switchgear, and finally to various distribution boxes. It's an electrical device that integrates switches, circuit breakers, and other protective devices. Traditional low-voltage switchgear mainly includes an internal main control switch. External lines first enter the main control switch and then the branch control switches. Each branch circuit is configured according to its needs, such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage compartments, and some have high-voltage busbars. Because high- and low-voltage switchgear contains numerous electrical devices and cables, monitoring cameras are typically installed inside to monitor their operation. However, traditional fixed-installation monitoring cameras have limited shooting angles and cannot comprehensively view the connections of all electrical devices and cable joints, resulting in generally poor monitoring effectiveness. Summary of the Invention

[0003] The purpose of this invention is to provide a stable and convenient intelligent low-voltage switchgear that can be used in large low-voltage switchgear structures. It facilitates maintenance in low-voltage switchgear and enables comprehensive monitoring and inspection, allowing for timely detection of problems and improving the convenience of maintenance and the stability of operation.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A stable and convenient intelligent low-voltage switchgear includes an outer cabinet, in which several low-voltage switchgear modules are provided. Each low-voltage switchgear module includes several drawer circuit units distributed vertically, with the inner ends of the drawer circuit units being continuous. A mobile monitoring device is provided on the inner side panel of the outer cabinet. The mobile monitoring device is slidably connected to the outer cabinet along the distribution direction of the low-voltage switchgear modules. The mobile monitoring device includes a monitoring head that slides vertically, with the monitoring head aligned with the drawer circuit unit at the corresponding position.

[0005] Furthermore, the outer cabinet also includes a heat sink with ventilation holes.

[0006] Furthermore, a movable baffle is provided on one side of the heat sink, which is slidably connected to the outer cabinet and blocks the heat dissipation hole or moves away from the heat dissipation hole.

[0007] Furthermore, the movable baffle is provided with a heat dissipation grille. The movable baffle is slidably connected to the outer cabinet. When the movable baffle moves to one end, the heat dissipation grille blocks all the heat dissipation holes. When it moves to the other end, all the heat dissipation holes are exposed.

[0008] Furthermore, push plates are connected to both sides of the movable baffle. The push plates are located on the moving path of the mobile monitoring device and are pushed and slid by the mobile monitoring device.

[0009] Furthermore, the movable baffle is located on the outside of the outer cabinet, and a sliding groove is opened on the outer cabinet. The push plate extends into the sliding groove and slides left and right along it.

[0010] Furthermore, the outer cabinet is connected to horizontal slide rails on both the upper and lower sides, and the upper and lower ends of the movable baffle are slidably connected to the corresponding horizontal slide rails.

[0011] Furthermore, the mobile monitoring device is also equipped with a fire extinguishing device. The nozzle of the fire extinguishing device is connected to the monitoring head and slides up and down to aim at the fire point.

[0012] Furthermore, a lower linear module and an upper guide rail are connected to the inner side panel of the outer cabinet. A vertical linear module is connected between the lower linear module and the upper guide rail. The vertical linear module moves horizontally under the drive of the lower linear module and the guidance of the upper guide rail. A sliding plate is connected to the vertical linear module. The sliding plate slides up and down under the drive of the vertical linear module, and a monitoring head is fixed on the sliding plate to drive its sliding.

[0013] In summary, the present invention has the following beneficial effects: The outer cabinet houses multiple low-voltage switchgear modules, suitable for large low-voltage switchgear structures. Each module includes several vertically distributed drawer circuit units for easy maintenance. The internal ends of these drawer circuit units are interconnected, allowing for comprehensive monitoring and inspection via internal mobile monitoring equipment. This enables precise imaging and temperature measurement of electrical equipment and cable joints, facilitating immediate problem detection and improving maintenance convenience and operational stability. Movable baffles allow for easy opening and closing of ventilation holes, providing different functions such as heat dissipation or waterproofing. An emergency fire-fighting function is also included, enhancing equipment safety. Attached Figure Description

Detailed Implementation

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0018] A stable and convenient intelligent low-voltage switchgear, such as Figure 1 As shown, it includes an outer cabinet 1, with several doors connected to the outside of the outer cabinet 1. It is used in large low-voltage switchgear structures. Several low-voltage switchgear modules 2 are placed side by side in the outer cabinet 1. The bottom of the low-voltage switchgear modules 2 is equipped with casters for easy movement. The back of the low-voltage switchgear modules 2 is open, and the interior includes several drawer circuit units 21 distributed vertically. The specific pull-out drawer circuit structure is existing technology and will not be described in detail here. In this embodiment, the inner end of the drawer circuit unit 21 is also open (i.e., no inner side panel of the drawer is provided, or the inner side panel is lower than the outer side panel of the drawer, so that the electrical equipment and cable joints in each drawer circuit unit 21 can be observed from the inside), which facilitates maintenance work and monitoring.

[0019] like Figure 2 As shown, a mobile monitoring device 3 is installed on the inner side panel of the outer cabinet 1. The mobile monitoring device 3 is slidably connected to the outer cabinet 1 along the distribution direction of the low-voltage cabinet module 2. The mobile monitoring device 3 includes a monitoring head 31 that slides up and down and a lighting lamp, etc. The monitoring head 31 and the lighting lamp are aligned with the corresponding drawer circuit unit 21. The mobile monitoring device 3 performs comprehensive monitoring and inspection work, accurately photographs and measures the temperature of electrical equipment and cable joints, so as to detect problems in time, improve the convenience of maintenance and the stability of operation. In this embodiment, a lower linear module and an upper guide rail are connected to the inner side plate of the outer cabinet 1. A base plate sliding plate is connected between the lower linear module and the upper guide rail. A vertical linear module is fixed on the base plate sliding plate. The vertical linear module moves horizontally under the drive of the lower linear module and the guidance of the upper guide rail. A sliding plate is connected to the vertical linear module. The sliding plate slides up and down under the drive of the vertical linear module. A monitoring head 31 and a lighting lamp are fixed on the sliding plate and move accordingly.

[0020] like Figure 2As shown, a fire extinguishing device 6 is also fixed on the sliding plate of the mobile monitoring device 3. The fire extinguishing device 6 includes a gas tank and a nozzle. The gas tank and the nozzle are connected by a flexible pipe and controlled to open and close by means of an electric valve. The gas tank of the fire extinguishing device 6 is fixed on the sliding plate of the base plate, so that it is connected to one side of the vertical linear module and slides horizontally together with the vertical linear module. The nozzle of the fire extinguishing device 6 is connected to the sliding plate, so that the vertical linear module only drives the nozzle of the fire extinguishing device 6 to move up and down. By controlling the nozzle of the fire extinguishing device 6 to slide up and down together with the monitoring head 31, it is aimed at the fire point, so that fire extinguishing work can be carried out in time when the fire is discovered, and losses can be reduced.

[0021] like Figure 2 and Figure 3 As shown, the outer cabinet 1 also includes a heat dissipation plate 4, on which several vertical strip-shaped heat dissipation holes are opened; a movable baffle 5 is also provided on one side of the heat dissipation plate 4, which is horizontally slidably connected to the outer cabinet 1 and is positioned in front of or away from the heat dissipation holes; a vertical heat dissipation grille 51 is opened on the movable baffle 5, the spacing of the heat dissipation grille 51 is adapted to the strip-shaped heat dissipation holes, and the movable baffle 5 is horizontally slidably connected to the outer cabinet 1. When the movable baffle 5 is moved to one end, the heat dissipation grille 51 blocks all the heat dissipation holes, and when it is moved to the other end, all the heat dissipation holes are exposed; the movable baffle 5 is designed to facilitate opening or closing the heat dissipation holes to achieve different functions such as heat dissipation or waterproofing. In this embodiment, push plates 52 are integrally connected to both sides of the movable baffle 5. The push plates 52 are located on the lateral movement path of the vertical linear module and are pushed and slid by the mobile monitoring device 3. In order to improve waterproofing, the movable baffle 5 is located on the outside of the outer cabinet 1. Two sliding grooves are opened on the outer cabinet 1. The push plates 52 extend into the corresponding sliding grooves and slide left and right along them (the push plates 52 are T-shaped and abut against the side wall of the inner side panel of the outer cabinet 1). The sliding grooves control the length of the sliding path. In order to improve the smoothness of its sliding, horizontal slide rails 11 are connected to the upper and lower sides of the back of the outer cabinet 1. The upper and lower ends of the movable baffle 5 are slidably connected to the corresponding horizontal slide rails 11.
