Description

Technical Field

[0001] This utility model belongs to the field of switch cabinets, and specifically relates to a detection device for a drawer unit. Background Technology

[0002] Drawer units are semi-finished products in the switchgear manufacturing process. During the final assembly process, drawer units are assembled with other units to form the switchgear. After final assembly, in order to ensure that each unit is in normal working order, the assembled switchgear needs to undergo power-on testing to repair or replace any malfunctioning parts.

[0003] Clearly, current technology involves inspecting the entire switchgear after final assembly. Therefore, in practice, when a drawer unit is found to be faulty, it must be removed individually from the assembled switchgear for separate maintenance or replacement. This method involves both assembly and disassembly of the drawer unit, resulting in low efficiency. Utility Model Content

[0004] This invention provides a detection device for drawer units, the purpose of which is to solve the problem of low efficiency in the detection of drawer units in the prior art.

[0005] To achieve the above objectives, this utility model provides a detection device for a drawer unit, including a working platform;

[0006] An overlap plate, corresponding to the work platform, is provided with a docking interface for docking with a drawer unit; and

[0007] The detection circuit is electrically connected to the docking interface. The detection circuit includes a power supply module. The docking interface is connected to the drawer unit, thereby connecting the drawer unit to the detection circuit.

[0008] In this solution, the operator mates the drawer unit with the lap plate. Since the mating interface on the lap plate connects to the detection circuitry, electrical connection between the drawer unit and the detection circuitry is achieved after the lap plate and drawer unit are mated. The detection circuitry can supply power to the drawer unit, and once the drawer unit is powered on, its status is determined. This detection method eliminates the need for complete assembly of the drawer unit, thus improving detection efficiency.

[0009] Preferably, to facilitate the operator's connection between the drawer unit and the connecting plate, the connecting plate in this solution is installed on the work platform. Installing the connecting plate on the work platform makes it easier for the operator at the work platform to perform operations.

[0010] To facilitate the operator in connecting the drawer unit to the lap plate, the lap plate described in this solution is installed vertically.

[0011] Preferably, the lap plate described in this solution is installed on the back side of the work platform, which facilitates operation by the operator from the front.

[0012] Preferably, to improve the detection efficiency of the drawer units, this solution uses at least two overlapping plates, each of which can be connected to a drawer unit individually. Since each overlapping plate can connect to one drawer unit, at least two drawer units can be detected simultaneously on the work platform, resulting in higher detection efficiency compared to detecting each drawer unit individually.

[0013] Preferably, to accommodate different drawer units, the connecting plate in this solution is movably installed. Different drawer units have different connectors when requiring testing. Therefore, different connecting plates can be replaced as needed for different drawer units, improving the applicability of the device.

[0014] Preferably, to ensure precise alignment between the drawer unit and the overlapping plate, this solution further includes a guide structure. This guide structure guides the drawer unit to its correct position on the overlapping plate, ensuring precise alignment. Furthermore, because the guide structure eliminates the need for manual alignment by the operator, thus improving efficiency.

[0015] Preferably, to guide the drawer unit, the guiding structure of this solution includes a guide groove and a guide portion, which are respectively disposed on the work platform and the drawer unit, and the guide portion and guide groove are fitted together for guidance. This solution achieves the guidance of the drawer unit through the fitting of the guide portion and guide groove, enabling the drawer unit to precisely align with the connecting plate.

[0016] Preferably, to ensure the drawer units can reach the work platform accurately and automatically, this solution also includes a conveyor belt connected to the work platform. This solution uses a conveyor belt to transport the drawer units, allowing them to be precisely transported to the work platform for inspection. By configuring a conveyor belt, operators are no longer required to bend over to pick up or put down the drawer units, reducing their workload. It also saves time and improves inspection efficiency.

[0017] Preferably, the conveyor belt and the working platform are on the same plane to facilitate the loading and unloading of the drawer units.

[0018] The beneficial effects of this utility model are as follows: In this solution, the operator mates the drawer unit with the overlapping plate, and since the mating interface on the overlapping plate is connected to the detection circuit, the electrical connection between the drawer unit and the detection circuit is achieved after the overlapping plate and the drawer unit are mated. The detection circuit can supply power to the drawer unit, and after the drawer unit is powered on, its status is determined. The detection method provided by this solution does not require the overall assembly of the drawer unit, thus improving detection efficiency. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0024] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0025] Example 1

[0026] The basics are as follows: Figure 1 To be continued Figure 2 As shown, a detection device for a drawer unit includes a work platform 1, a connecting plate 2, and a detection module 3.

[0027] The work platform 1 in this embodiment is a rectangular platform, which can be formed by welding and assembling several columns, beams, and flat plates. The surface of the work platform 1 is used for operators to perform inspection operations. A lap plate 2 is provided on the back side of the work platform 1. The lap plate 2 is rectangular and has a docking interface 21, which can dock with the drawer unit. The specific type of the docking interface 21 is adapted to the type of plug configured on the drawer unit. After docking with the drawer unit, the docking interface 21 achieves electrical connection with the drawer unit. The relevant structures of the docking interface 21 and the drawer unit's plug can refer to the prior art.

[0028] In this embodiment, the overlapping plate 2 is installed on the back side of the work platform 1, and preferably, the overlapping plate 2 is detachably installed. Specifically, a mounting frame, which is rectangular, can be provided on the back side of the work platform 1. The mounting frame and the overlapping plate 2 are connected by fasteners, thereby achieving detachable installation of the overlapping plate 2. Alternatively, the overlapping plate 2 can be directly installed on the back side of the work platform 1 using fasteners (such as bolts), also achieving installation of the overlapping plate 2. After installation, the overlapping plate 2 is a vertical device. When it is necessary to replace the overlapping plate 2, simply loosen the fasteners, and the overlapping plate 2 can be separated from the work platform 1.

[0029] Understandably, since the connecting plate 2 is in a movable installation state, it can be disassembled and replaced for different types of drawer units. This allows the mating interface 21 on the connecting plate 2 to be compatible with the plug type of the drawer unit, thus enabling the connecting plate 2 and the drawer unit to connect. After the mating interface 21 is connected to the plug of the drawer unit, the drawer unit and the mating interface 21 are electrically connected.

[0030] To improve the detection efficiency of drawer units, each work platform 1 is equipped with at least two overlapping plates 2, and more preferably two overlapping plates. The two overlapping plates 2 are arranged side by side, and each overlapping plate 2 can be adapted to one drawer unit, thereby realizing the detection of two drawer units.

[0031] To achieve precise alignment between the overlapping plate 2 and the drawer unit, this embodiment also includes a guide structure. The guide structure comprises guide grooves 4 and guide portions, which are guide protrusions located on both sides of the drawer unit. The guide grooves 4 are rectangular grooves, arranged in pairs opposite each other, each adapting to the guide portions on either side of the drawer unit. The guide portions slide within the guide grooves 4, guiding the drawer unit to move and achieving precise alignment between the drawer unit and the overlapping plate 2.

[0032] In this embodiment, the detection module 3 is located on the back side of the work platform 1. The detection module 3 contains a detection circuit, which is electrically connected to the docking interface 21 on the connecting plate 2. A power supply module, which can be a battery or an external power source, is configured within the detection circuit. When the drawer unit is docked with the connecting plate 2, the drawer unit is connected to the detection circuit. The detection circuit can supply power to the drawer unit, allowing the operator to test its functions. Simultaneously, the detection circuit can also be equipped with detection instruments (e.g., ammeters and voltmeters, as used in the prior art), which can detect relevant parameters of the drawer unit to determine its status.

[0033] The following detailed description illustrates the specific implementation method: When testing the drawer unit, the drawer unit is guided by the guide structure and docks with the overlap plate 2. After docking, since the overlap plate 2 is connected to the detection circuit, the drawer unit and the detection circuit are electrically connected. The detection circuit supplies power to the drawer unit to detect whether there is a fault in the drawer unit.

[0034] If a fault is detected in the drawer unit, the unit will be marked for subsequent maintenance and replacement. If no fault is detected in the drawer unit, it can be directly used in the subsequent switch cabinet assembly process.

[0035] After one drawer unit has been tested, the operator disconnects the drawer unit from the connecting plate 2. Then, another drawer unit is connected to the connecting plate 2, and the drawer units are tested in sequence.

[0036] Example 2

[0037] This embodiment is an improvement on embodiment 1, such as... Figure 3 As shown, to facilitate the movement of the drawer units and reduce the time spent by operators manually picking up and placing the drawer units, this embodiment also includes a conveyor belt 5, which is installed on the side of the work platform 1. The assembled drawer unit moves from the conveyor belt 5 to the work platform 1, where the operator picks up the drawer unit for inspection. Simultaneously, the height of the work platform 1 is at the same level as the conveying surface of the conveyor belt 5, thus facilitating the movement of the drawer unit from the conveyor belt 5 to the work platform 1.

[0038] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
