Description
Technical Field
[0001] This utility model relates to the technical field of electrical equipment, and in particular to a sensing mechanism for a switch cabinet in a distribution box. Background Technology
[0002] In power systems, distribution boxes are key equipment for power distribution and control. Their stability and reliability are crucial to the operation of the entire power system, and the sensors inside the distribution boxes also play a vital role.
[0003] However, in existing technologies, the placement of sensors in distribution boxes presents a series of problems, severely impacting the operational efficiency and safety of the distribution boxes and their switchgear. For example, current distribution box designs often lack unified standards and specifications for sensor placement, resulting in disorganized sensor locations and making it difficult to quickly and accurately locate the required sensors. Due to the unclear sensor locations, maintenance personnel need to spend a significant amount of time and effort searching for sensors during routine maintenance and troubleshooting, which not only reduces maintenance efficiency but also increases maintenance costs. On the other hand, switch sensors in distribution box switchgear are crucial components for monitoring and controlling switch status. Existing technologies typically employ contact sensors, which are prone to malfunction for various reasons, and once they fail, there are no effective verification methods. Utility Model Content
[0004] To address the technical problems of unclear sensor placement in current distribution boxes, low efficiency in daily maintenance and troubleshooting, high maintenance costs, and frequent malfunctions of switch sensors, this utility model provides a switch cabinet sensing mechanism for distribution boxes.
[0005] Specifically, this utility model provides a sensing mechanism for a switch cabinet in a power distribution box, including a cabinet body and a cabinet door. The cabinet door is rotatably mounted on the cabinet body. The mechanism also includes a sensor component and a connecting rod. The sensor component includes a slide rail, an assembly box, and a sensor. The slide rail is mounted on the side of the cabinet body and is positioned from the cabinet body toward the cabinet door. The assembly box is slidably mounted on the slide rail, and the sensor is directly or indirectly mounted on the assembly box. The assembly box is connected to the cabinet door via the connecting rod. When the cabinet door opens and closes, the connecting rod drives the assembly box to move on the slide rail.
[0006] Furthermore, mounting seats are provided on the assembly box and the cabinet door respectively, and the two ends of the connecting rod are connected to the mounting seats on the assembly box and the cabinet door respectively.
[0007] Furthermore, the end of the connecting rod is provided with a limiting part, the mounting base is provided with a groove, and the limiting part of the connecting rod is limited and disposed on the groove of the mounting base.
[0008] Furthermore, the top of the slot seat has a slot, and the side has a clearance channel. The diameter of the limiting part is larger than the clearance channel of the slot seat.
[0009] Furthermore, the mounting base also includes a fastener, which is positioned at the entrance of the air-avoidance channel, and the fastener is provided with a barb at the entrance.
[0010] Furthermore, the side of the cabinet is provided with a sensor working area and a maintenance area. The sensor working area is located inside the cabinet, and the maintenance area is adjacent to the cabinet door. The slide rail extends from the sensor working area to the sensor maintenance area.
[0011] Furthermore, the slide rail is provided with raised ridges on both sides, and the assembly box is provided with slots that are adapted to the raised ridges. The assembly box is slidably installed on the slide rail through the cooperation of the slots and the raised ridges.
[0012] Furthermore, a first boss is formed by a protrusion in the middle of the assembly box, which is used to place the sensitive element of the sensor.
[0013] Furthermore, the sensor includes a displacement sensor for sensing the movement state of the assembly box.
[0014] Furthermore, the sensor component is disposed on the side of the cabinet where it connects to the cabinet door.
[0015] This invention integrates sensors within a distribution box using an assembly box. A sliding rail and connecting rod connect the assembly box to the cabinet door, allowing the sensor components to be moved and pulled out when the cabinet door is opened. This facilitates sensor replacement or repair by maintenance personnel, allowing them to avoid electrical components within the distribution box.

[0033] Example 1:
[0034] See Figure 1-5 To address the current problems of disorganized sensor placement and unclear locations in distribution boxes, leading to maintenance difficulties, and the susceptibility of switch sensors in distribution box switchgear to malfunction, this embodiment provides a switchgear sensing mechanism for distribution boxes. This mechanism optimizes the placement of the sensor component 30, allowing it to be pulled out when the switchgear door 20 is opened, enabling maintenance personnel to quickly locate the sensor component 30 and facilitate maintenance. Specifically, the sensor is integrated into the assembly box 32 and connected to the cabinet door 20 via a connecting rod 40. When the cabinet door 20 is opened or closed, the connecting rod 40 drives displacement along the slide rail 31. In this embodiment, the sensor includes at least a displacement sensor, which indicates the opening and closing of the cabinet door 20 through the movement of the sensor component 30, thus providing auxiliary switching sensing.
[0035] In terms of overall structure, the sensing mechanism of the switch cabinet for the distribution box in this embodiment specifically includes a cabinet body 10, a cabinet door 20, a sensor component 30, and a connecting rod 40. The cabinet door 20 is rotatably mounted on the cabinet body 10, and its rotation enables opening and closing operations. The sensor component 30 includes a slide rail 31, an assembly box 32, and a sensor. The slide rail 31 is mounted on the side of the cabinet body 10 and extends from the cabinet body 10 toward the cabinet door 20. The assembly box 32 is slidably mounted on the slide rail 31, and the sensor is directly or indirectly mounted on the assembly box 32. The assembly box 32 is connected to the cabinet door 20 via the connecting rod 40. When the cabinet door 20 opens and closes, the connecting rod 40 drives the assembly box 32 to move along the slide rail 31. The slide rail 31 serves as a support and guide, allowing the assembly box 32 to slide between the working area and the maintenance area. Assembly box 32 is used to assemble sensors and is connected to cabinet door 20 via a transmission mechanism. It moves on slide rail 31 during the opening and closing of cabinet door 20. When cabinet door 20 is closed, assembly box 32 is placed in a predetermined position, enabling the sensors above it to monitor data indicators such as temperature, humidity, water immersion, and smoke inside the distribution box. Sensors are installed in various layouts depending on the situation, including but not limited to temperature and humidity sensors, SF6 sensors, water immersion sensors, smoke sensors, current sensors, switch sensors, and displacement sensors.
[0036] Please see Figure 1-5 The following provides some specific implementation methods for this embodiment.
[0037] As a preferred embodiment of the above solution, mounting seats 50 are respectively provided on the assembly box 32 and the cabinet door 20, and the mounting seats 50 are used to install the connecting rod 40. Specifically, both ends of the connecting rod 40 are connected to the mounting seats 50 on the assembly box 32 and the cabinet door 20, respectively. When the cabinet door 20 is opened, the connecting rod 40 drives the assembly box 32 to slide on the slide rail 31 to the maintenance area. Preferably, the mounting seat 50 on the assembly box 32 is located on the side of the assembly box 32 closest to the cabinet door 20, and the mounting seat 50 on the cabinet door 20 is flush with the assembly box 32. When the cabinet door 20 is opened while the door is closed, the connecting rod 40 pulls the assembly box 32 towards the cabinet door 20, making it easier for maintenance personnel to avoid electrical components inside the distribution box and replace or repair the sensor.
[0038] As a preferred embodiment of the above solution, the end of the connecting rod 40 is provided with a limiting part 41, and the mounting base 50 is provided with a groove 51. The limiting part 41 of the connecting rod 40 is limited and positioned on the groove 51 of the mounting base 50. Specifically, the groove 51 has a groove at the top and a clearance channel 52 on the side. The diameter of the limiting part 41 is larger than the clearance channel 52 of the groove 51. During assembly, the limiting part of the connecting rod 40 is inserted into the groove 51 through the opening, and the rod body 42 of the connecting rod 40 passes through the clearance channel 52. Preferably, the mounting base 50 also includes a fastener 53, which is located at the entrance of the clearance channel 52. The fastener 53 is barbed at the entrance, meaning that the inner side of the fastener 53 is flat and the outer side is inclined. After the rod body 42 of the connecting rod 40 is engaged in the clearance channel 52 through the inclined side of the fastener 53, the connecting rod 40 cannot be dislodged without manual operation. Specifically, the fastener 53 is an elastic fastener. When the rod body 42 of the connecting rod 40 is inserted into the clearance channel 52, the fastener 53 can avoid displacement so that after the rod body 42 is inserted, it can reset and play a limiting role.
[0039] As a preferred embodiment of the above scheme, the side of the cabinet 10 is provided with a sensor working area and a maintenance area. The sensor working area is located inside the cabinet 10, and the maintenance area is adjacent to the cabinet door 20. The slide rail 31 extends from the sensor working area to the sensor maintenance area. This design allows the sensor component 30 to be in the sensing area when the cabinet door 20 is closed and the power distribution box is working normally. However, when maintenance personnel open the box for inspection, the sensor component 30 is taken out, facilitating maintenance and repair.
[0040] Regarding the internal arrangement of the sensor component 30, preferably, the slide rail 31 has raised ridges on both sides, and the assembly box 32 has slots that fit the raised ridges. The upper and lower sides of the slots fit the raised ridges respectively, and the assembly box 32 is slidably mounted on the slide rail 31 through the cooperation of the slots and raised ridges. This snap-fit method can ensure the firmness of the assembly box 32. Of course, the smoothness of sliding can be improved by adding sliding wheels at the connection points, which will not be elaborated in this embodiment. Regarding the installation of the sensor, preferably, the middle of the assembly box 32 protrudes to form a first boss 321. The first boss 321 is used to place the sensitive element of the sensor. The design of the first boss 321 facilitates the setting and layout of the sensitive elements of sensors of different models and layouts.
[0041] Additionally, the switch cabinet sensing mechanism can also be used to sense the opening and closing of the cabinet door 20. Specifically, the sensor includes a displacement sensor for sensing the movement of the assembly box 32. The displacement sensor determines and records the opening and closing status of the cabinet door 20 based on the displacement of the sensor component 30, thus monitoring the opening and closing status of the cabinet door 20 and sending the corresponding data to the controller. In a specific location, the sensor component 30 is positioned on the side of the cabinet 10 connected to the cabinet door 20, ensuring that the opening and closing of the cabinet door 20 is unaffected and that the opening range is sufficiently large. Preferably, the sensor component 30 is positioned near the bottom of the cabinet 10. The assembly box 32 contains an integrated circuit board for sensors, with multiple sensors integrated within it. This allows for pre-assembly, maintenance, and replacement, improving installation efficiency. Simultaneously, the assembly box 32 can be designed to be waterproof and fireproof to extend the lifespan of the sensors.
