Description

Technical Field

[0001] The present application relates to the technical field of power distribution equipment, and in particular to a combined high-explosive cabinet structure. Background Art

[0002] High-explosive cabinets, also known as explosion-proof cabinets, are specially designed to store and protect flammable, explosive, toxic, corrosive, and other hazardous chemicals. Their primary function is to prevent chemical spills, fires, and explosions, while also ensuring the safety of employees and property.

[0003] In related art, a combined high-explosive cabinet includes an outer casing, a main feeder and a branch feeder mounted within the outer casing, circuit breakers mounted within the main feeder and branch feeder, a circuit breaker cart for mounting the circuit breaker, and plug-in terminals connected to the circuit breaker. The outer casing includes side panels and a cabinet door. The circuit breaker cart is connected to a screw, which is connected to the cabinet door. To install the circuit breaker, after the cabinet door is closed, the screw is manually cranked or controlled by a motor to rotate, thereby controlling the movement of the circuit breaker cart into the main feeder and branch feeder, thereby electrically connecting the circuit breaker to the plug-in terminals and ensuring normal operation of the circuit breaker.

[0004] However, when installing the circuit breaker in the above-mentioned combined high-explosive cabinet, the staff cannot observe whether the circuit breaker is properly connected to the plug-in terminal outside the cabinet door, which is inconvenient for installation and needs to be improved. Utility Model Content

[0005] In order to improve the convenience of connecting the circuit breaker and the plug-in terminal, the present application provides a combined high-explosive cabinet structure.

[0006] The combined high-explosive cabinet structure provided in this application adopts the following technical solution:

[0007] A combined high-explosive cabinet structure includes a shell, a circuit breaker arranged in the shell, and a plug-in terminal arranged in the shell. The shell includes an upper plate, a bottom plate, side plates and a plurality of cabinet doors. The upper plate and the bottom plate are arranged relative to each other. The cabinet doors are detachably connected to the side plates. The side plates are provided with sliding holes above the cabinet doors. An indicator rod is slidably arranged in the sliding hole. A connecting rod assembly is provided in the shell. When the circuit breaker moves in a direction away from the cabinet door, the connecting rod assembly can drive the indicator rod to slide in a direction extending out of the shell.

[0008] By adopting the above technical solution, when the circuit breaker is installed, when the circuit breaker moves away from the cabinet door, the connecting rod assembly pushes the indicator rod in the direction of extending out of the housing, causing the indicator rod to slide in the sliding hole in the direction of extending out of the housing. When the circuit breaker moves into the cabinet to complete the circuit connection with the plug-in terminal, the indicator rod automatically extends out of the housing. The staff can visually judge the connection status by the position of the indicator rod without opening the cabinet. This solves the technical pain point of traditional cabinets that cannot be observed from the outside, significantly improves operational safety and efficiency, and increases the convenience of connecting the circuit breaker to the plug-in terminal. In addition, after the indicator rod extends out of the housing, it is located above the cabinet door. The cabinet door usually needs to move upward when opening. Therefore, the indicator rod can prevent the cabinet door from opening when the circuit breaker is energized, forming a safety lock and reducing the risk of staff opening the cabinet door while it is energized.

[0009] Optionally, the connecting rod assembly includes a rotating shaft arranged on the inner wall of the upper plate, a transmission rod rotatably arranged on the rotating shaft, the middle part of the transmission rod is rotatably connected to the rotating shaft, one end of the transmission rod is rotatably connected to the indicator rod, and the other end is rotatably provided with a trigger rod, and a trigger member is provided on the housing of the circuit breaker. When the circuit breaker moves in a direction away from the cabinet door, the trigger member can drive the trigger rod to move in a direction away from the cabinet door.

[0010] By adopting the above technical solution, when the circuit breaker moves away from the cabinet door, it drives the trigger member away from the cabinet door, thereby driving the trigger rod away from the cabinet door, and thus driving the end of the transmission rod connected to the indicator rod toward the cabinet door, thereby driving the indicator rod to extend out of the housing, prompting the staff that the circuit breaker is properly connected to the plug-in terminal. The lever structure of the rotating shaft and transmission rod is used to amplify the circuit breaker's tiny displacement and convert it into a significant extension of the indicator rod, ensuring clear and reliable status indication. The trigger rod design ensures precise linkage between the circuit breaker movement and the indicator rod, avoiding misjudgment and providing high structural stability to adapt to the vibration environment of high-explosive cabinets.

[0011] Optionally, the trigger member includes a connecting plate provided on the housing of the circuit breaker, and the connecting plate is located on a side of the trigger rod close to the cabinet door.

[0012] By adopting this technical solution, when the circuit breaker moves into the cabinet, it drives the connecting plate away from the cabinet door, thereby pushing the trigger rod away from the cabinet door, and thus the indicator rod toward the cabinet door. As a rigid trigger component, the connecting plate is low-cost and transmits force directly, eliminating elastic deformation that can cause delays in indication. This ensures that the indicator rod can extend from the housing promptly to provide an indication.

[0013] Optionally, the connecting plate is detachably connected to the circuit breaker housing.

[0014] By adopting the above technical solution, when installing connecting plates on circuit breakers of different sizes, the original connecting plate can be removed first, and then the new connecting plate can be installed on the circuit breaker of different sizes. For example, the lower the height of the circuit breaker, the higher the connecting plate needs to be. This ensures that the connecting plate can properly push the trigger lever when the circuit breaker is moved, improving the adaptability of the connecting plate to circuit breakers of different heights and sizes. If the connecting plate is damaged, it can be removed and a new one installed without replacing the entire circuit breaker, reducing maintenance costs and conserving resources.

[0015] Optionally, the connecting plate is connected to the circuit breaker housing via connecting bolts.

[0016] By adopting the above technical solution, when the connecting plate needs to be installed on the circuit breaker housing, it is only necessary to tighten the connecting bolts on the connecting plate and the circuit breaker housing. This simple operation improves the stability of the connection between the connecting plate and the circuit breaker housing, making the connecting plate less likely to loosen in a vibrating environment, thereby ensuring the long-term reliability of the indicator rod. When the connecting plate needs to be removed from the circuit breaker housing, it is only necessary to loosen the connecting bolts, which is a convenient operation.

[0017] Optionally, the indicator rod includes an indicating portion slidably arranged in a sliding hole and an extension portion rotatably connected to a transmission rod, the extension portion being arranged on a side of the indicating portion away from the cabinet door, a limiting ring being provided on the extension portion, an outer diameter of the limiting ring being larger than a diameter of the extension portion, an elastic member being provided between the inner wall of the side panel and the limiting ring, and the elastic member being capable of driving the indicator rod to slide in a direction close to the transmission rod.

[0018] By adopting the above technical solution, when the circuit breaker moves toward the cabinet door, the connecting plate no longer pushes the trigger rod to move. At this time, the elastic member pushes the indicator rod away from the cabinet door, causing the indicator portion to slide toward the transmission rod, thereby causing the indicator portion to slide into the housing and no longer indicate the connection status between the circuit breaker and the plug-in terminal. This reduces the possibility that the indicator rod will still indicate the connection between the circuit breaker and the plug-in terminal after the circuit breaker is removed from the housing, reducing the risk of misleading personnel. The elastic member pulls the indicator rod back when the circuit breaker is withdrawn, dynamically reflecting the disconnection status. At the same time, the preload force of the elastic member prevents the indicator rod from accidentally extending due to vibration, ensuring the accuracy of the indication.

[0019] Optionally, the elastic member includes a return spring sleeved on the extension portion, one end of the return spring abuts against the limiting ring, and the other end abuts against the inner wall of the side plate.

[0020] By adopting this technical solution, when the transmission rod pushes the indicator rod toward the cabinet door, the return spring cushions the impact of the transmission rod on the indicator rod, extending the service life of the indicator rod and connecting rod assembly. The return spring also provides the retraction force to reset the indicator rod. Its placement along the axis of the indicator rod saves cabinet space and accommodates the compact design of high-explosive cabinets.

[0021] Optionally, an anti-slip portion is provided at one end of the indicating portion away from the extending portion, and a width of the anti-slip portion is greater than a diameter of the sliding hole.

[0022] By adopting the above technical solution, when the cabinet body vibrates, the anti-slip part can limit the indicating part in the sliding hole, so that the indicating part is not easily slipped out of the sliding hole due to vibration, thereby reducing the possibility of the indicating rod being lost or stuck in the cabinet and causing malfunction, which is conducive to maintaining the integrity of the system, meeting the high safety standards of explosion-proof equipment, and ensuring that the indicating rod can play its indicating role normally.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. An indicator rod is slidably mounted on the side panel, and a transmission rod pushes the indicator rod out of the housing during the process of moving the circuit breaker into the cabinet, thereby indicating the connection status between the circuit breaker and the plug-in terminal, making it easier for staff to determine whether the circuit breaker is properly installed;

[0025] 2. A detachable connecting plate for pushing the trigger rod is installed on the circuit breaker housing. The rigid connection drives the transmission rod to rotate, ensuring the timeliness of the indication effect.

[0026] 3. A reset spring is sleeved on the extension part. When the connection plate releases the limit on the trigger rod, the reset spring will drive the indicator rod to retract and reset, thereby indicating the disconnection state of the circuit breaker and the plug-in terminal.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiments of the present application disclose a combined high-explosive cabinet structure.

[0034] Reference Figure 1 and Figure 2 A combined high-explosive cabinet structure includes multiple main feeders 1 and branch feeders 2. Each main feeder 1 and branch feeder 2 includes a housing 11, a circuit breaker 12 disposed within the housing 11, and plug-in terminals 13 disposed within the housing 11. The housing 11 includes an upper plate 111, a bottom plate 112, side plates 113, and a plurality of cabinet doors 114. The upper plate 111 and the bottom plate 112 are disposed opposite each other, with the upper plate 111 disposed above the bottom plate 112. The side plates 113 are fixed between the upper plate 111 and the bottom plate 112. The cabinet doors 114 are detachably connected to the side plates 113. To open the cabinet doors 114, they are typically slid away from the bottom plate 112.

[0035] Reference Figure 2 and Figure 3 The side panel 113 defines a sliding hole 3 above the cabinet door 114. An indicator rod 4 is slidably disposed in the sliding hole 3. The indicator rod 4 includes an indicator portion 41 slidably disposed in the sliding hole 3, and an extension portion 42 disposed at the end of the indicator portion 41 away from the cabinet door 114. The extension portion 42 is provided with a retaining ring 421. The outer diameter of the retaining ring 421 is larger than the diameter of the extension portion 42. An anti-slip portion 411 is provided at the end of the indicator portion 41 away from the extension portion 42. In this embodiment, the anti-slip portion 411 is annular and has a diameter larger than the diameter of the sliding hole 3.

[0036] Reference Figure 3An elastic member 5 is provided between the inner wall of the side plate 113 and the retaining ring 421. The elastic member 5 includes a return spring 51 that is sleeved on the extension portion 42. One end of the return spring 51 abuts the retaining ring 421, and the other end abuts the inner wall of the side plate 113. When the indicator portion 41 slides toward the outside of the housing 11, the return spring 51 is compressed. When the indicator portion 41 slides toward the inside of the housing 11, the return spring 51 expands, providing the force that forces the indicator portion 41 to slide toward the inside of the housing 11.

[0037] Reference Figure 1 and Figure 3 A connecting rod assembly 6 is disposed within the housing 11. The connecting rod assembly 6 includes a rotating shaft 61 fixed to the inner wall of the upper plate 111 and a transmission rod 62 rotatably mounted on the rotating shaft 61. The middle portion of the transmission rod 62 is rotatably connected to the rotating shaft 61, so that both ends of the transmission rod 62 can rotate around the rotating shaft 61. One end of the transmission rod 62 is rotatably connected to the extension portion 42, and the other end is rotatably mounted with a trigger lever 7.

[0038] Reference Figure 3 The extension portion 42 defines an insertion slot 422, and connecting holes 423 are defined in the opposite walls of the insertion slot 422. A fixing hole 621 is defined on the end of the transmission rod 62 near the extension portion 42. A rotating shaft 622 is provided through the connecting hole 423 and the fixing hole 621 for mutual rotation. A connecting post 71 is defined on the end of the trigger lever 7 near the transmission rod 62. A rotating hole 623 is defined on the end of the transmission rod 62 near the trigger lever 7, and the connecting post 71 is rotatably mounted in the rotating hole 623.

[0039] Reference Figure 3 The elastic member 5 in this embodiment is preferably a return spring 51. In other cases, other elastic members 5 can also be selected according to customer needs, such as a spring arranged between the limiting ring 421 and the inner wall of the side plate 113, a torsion spring sleeved on the rotating shaft 622, etc.

[0040] Reference Figure 2 and Figure 3 The housing of the circuit breaker 12 is provided with a trigger member 8, which includes a connecting plate 81 provided on the housing of the circuit breaker 12. The connecting plate 81 is located on the side of the trigger rod 7 close to the cabinet door 114. The connecting plate 81 is detachably connected to the housing of the circuit breaker 12 via connecting bolts 82.

[0041] The implementation principle of a combined high-explosive cabinet structure in an embodiment of the present application is as follows: when the circuit breaker 12 is moved into the housing 11 by hand cranking or electric control, the connecting plate 81 is driven to move toward the trigger rod 7, thereby driving the trigger rod 7 and one end of the transmission rod 62 to move away from the cabinet door 114, so that the end of the transmission rod 62 connected to the indicator rod 4 rotates toward the cabinet door 114, thereby causing the indicator rod 4 to extend out of the housing 11 to prompt the staff that the circuit breaker 12 is properly connected to the plug-in terminal 13. This facilitates the connection of the circuit breaker 12 with the plug-in terminal 13, solving the industry problem of the invisible connection status of the high-explosive cabinet circuit breaker 12. At the same time, after the indicator rod 4 extends out of the housing 11, it is located above the cabinet door 114, preventing the cabinet door 114 from opening, forming a safety lock, and reducing the risk of operating the circuit breaker 12 under power.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
