Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an electromagnetically shielded power distribution cabinet. Background Technology

[0002] Distribution cabinets are indispensable key equipment in power systems, used for the distribution, control, metering of electrical energy and protection of lines. They integrate a large number of electrical components, instruments and signal processing units. With the increasing demands of modern industry for automation and informatization, the integration of components inside distribution cabinets is becoming higher and higher, and signal processing is becoming more and more precise, which makes the electromagnetic environment inside the cabinet increasingly complex.

[0003] In the conventional assembly and wiring process of power distribution cabinets, a large number of power cables and signal wires need to be laid in a limited space. For ease of assembly, these cables are often bundled together or laid haphazardly. When currents or signals of different natures are transmitted in the cables, electromagnetic coupling interference, i.e., crosstalk, is easily generated between closely parallel cables. This interference can seriously affect the data acquisition accuracy of precision instruments, reduce the stability of signal processing components, and may even lead to misjudgment of the control system, posing a potential threat to the safe and stable operation of the entire power system.

[0004] Furthermore, the components of the distribution cabinet are usually mounted on one or more mounting plates, and then the mounting plates are fixed inside the cabinet. The existing mounting plate fixing methods mostly use bolts for direct fastening. When the mounting plate needs to be disassembled for on-site installation or later maintenance, the operator has to disassemble and install multiple bolts one by one in the narrow cabinet space. The whole process is not only time-consuming and labor-intensive, which greatly reduces the efficiency of construction and maintenance, but also prolongs the downtime of the equipment in emergency repair scenarios.

[0005] Therefore, this utility model proposes an electromagnetically shielded power distribution cabinet to overcome the shortcomings of the prior art. Utility Model Content

[0007] This utility model provides an electromagnetic shielded power distribution cabinet, including: a cabinet body, a cabinet door, and a mounting plate disposed inside the cabinet body; as well as multiple fixing mechanisms and multiple mounting mechanisms.

[0008] The fixing mechanism is used to clamp and separate the wires, and the mounting mechanism is used to detachably fix the mounting plate.

[0009] Furthermore, the cabinet door is hinged to the cabinet body, and the fixing mechanism is disposed on the mounting plate, which detachably fixes the mounting plate to the inner wall of the cabinet body.

[0011] Preferably, the transmission assembly includes a rotating shaft rotatably passing through the fixed block, the rotating shaft being coaxially connected to the rocker arm; the transmission assembly also includes a helical gear one mounted on the rotating shaft, a helical gear two meshing with the helical gear one, a sawtooth disk one driven by the helical gear two, and a sawtooth disk two meshing with the sawtooth disk one and jointly disposed on the top wall of the fixed frame.

[0012] Preferably, the clamping block is connected to the first sawtooth disk and the second sawtooth disk respectively via a connecting rod, so as to be driven by them.

[0013] Preferably, the mounting mechanism includes a locking block driven by a rotating bolt, the locking block being able to be inserted into or disengaged from a mounting slot formed on the mounting plate to lock or unlock the mounting plate.

[0014] Preferably, the installation mechanism further includes a slider fixed to the inner wall of the cabinet; the outer wall of the installation plate is provided with an installation block, the installation groove is opened in the installation block, and the installation block is slidably engaged with the slider.

[0015] Preferably, the mounting mechanism further includes a connecting frame, the rotation of the bolt drives the connecting frame, and the connecting frame drives the locking block to translate.

[0016] Preferably, the installation mechanism further includes a fixing plate and a sliding rod fixed to the inner wall of the cabinet, and the locking block is sleeved on the sliding rod and slides along its length.

[0017] Preferably, a shielded connector is mounted on the front side of the mounting plate, and the wire is connected to the shielded connector.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting a gear linkage fixing mechanism controlled by a rocker arm, realizes the independent clamping and separation of wires inside the cabinet, which solves the problem of electromagnetic coupling interference caused by mixed cable laying in the prior art, thus affecting the signal processing accuracy and system stability of the equipment, and achieves the technical effect of ensuring neat and orderly wiring and improving the anti-interference capability of the equipment.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an electromagnetically shielded power distribution cabinet, which aims to solve the problems of messy internal cable laying in the power distribution cabinet that easily leads to electromagnetic coupling interference, as well as the complex and inefficient process of component installation and disassembly in the prior art.

[0024] like Figure 1 and Figure 2As shown, the electromagnetic shielded distribution cabinet includes a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1. The cabinet body 1 serves as the mounting base and outer shell of the entire device. The cabinet door 2 is used to open or close the cabinet body 1. Multiple mounting mechanisms 4 for detachably fixing components are fixedly connected to the inner wall of the cabinet body 1. The cabinet body 1 is also provided with a mounting plate 5 that is installed through the mounting mechanisms 4.

[0025] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the electromagnetic shielded distribution cabinet further includes multiple fixing mechanisms 3, and the fixing mechanisms 3 and the mounting plate 5 form a specific structural cooperation and connection relationship.

[0026] Please refer to the following carefully. Figure 2 and Figure 3 The structure will be described in detail below: The fixing mechanism 3 is located on the front side of the mounting plate 5. A shielded connector 6 is also fixedly mounted on the front side of the mounting plate 5. The wire 7 is connected to the shielded connector 6. The function of the fixing mechanism 3 is to distinguish and clamp the wire 7. The fixing mechanism 3 includes a fixing frame 302 and a fixing block 303 mounted on the fixing frame 302. The fixing mechanism 3 also includes a set of transmission components for driving and a pair of clamping blocks 308 driven by the transmission components to achieve opening or closing action. The transmission components include a rotating shaft 301 rotatably passing through the fixing block 303. One end of the rotating shaft 301 is coaxially connected to a rocker arm 306. A sleeve is fitted on the rotating shaft 301. Equipped with a helical gear 304, the transmission assembly also includes a helical gear 305 meshing with the helical gear 304, a sawtooth disk 307 driven by the helical gear 305, and a sawtooth disk 310 meshing with the sawtooth disk 307 and rotatably mounted on the top wall of the fixed frame 302. The clamping block 308 is connected to the sawtooth disk 307 and the sawtooth disk 310 respectively via a connecting rod 309, thereby being driven to clamp the wire 7. This structure, which controls the opening and closing of the clamping block 308 through gear linkage, ensures that the wire 7 can be neatly separated and fixed, effectively avoiding electromagnetic coupling interference caused by mixed cable laying.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve quick installation and removal of the mounting plate 5, please refer to the following: Figure 2 and Figure 4The installation mechanism 4 includes a fixed plate 406, which is vertically fixed to the inner wall of the cabinet 1. A slider 403 and a slide rod 407 are fixedly installed on the fixed plate 406. An installation block 402 is fixedly connected to the outer wall of the installation plate 5. The installation block 402 is slidably fitted onto the slider 403. An installation groove 401 is provided in the installation block 402. The installation mechanism 4 also includes a bolt 408 that is rotatably inserted through the fixed plate 406. The bolt 408 is threadedly connected to a connecting frame 405. The connecting frame 405 is connected to a locking block 404. The locking block 404 is sleeved on the slide rod 407 and can slide along its length. The locking block 404 can be inserted into or disengaged from the installation groove 401 by translation, thereby locking or unlocking the installation plate 5.

[0028] Working principle: The cabinet 1 has a cabinet door 2 on the front side. An installation plate 5 is installed on the rear side of the inner wall of the cabinet 1. A shielded connector 6 is installed on the front side of the installation plate 5. Multiple wires 7 are equidistantly connected to the outer wall of the shielded connector 6. Multiple fixing mechanisms 3 are equidistantly installed on the outer wall of the installation plate 5. The fixing mechanisms 3 are used to distinguish the wires 7. When in use, first rotate the rocker arm 306. The rocker arm 306 drives the rotating shaft 301 and the first helical gear 304 to rotate on the inner wall of the fixing block 303. The first helical gear 304 drives the second helical gear 305. The second helical gear 305 drives the first sawtooth disk 307 to rotate. The first sawtooth disk 307 meshes with it. The second sawtooth disk 310 rotates on the top wall of the fixed frame 302, allowing the second sawtooth disk 310 and the first sawtooth disk 307 to open and close on the top wall of the fixed frame 302. The first sawtooth disk 307 and the second sawtooth disk 310 simultaneously pull the clamping block 308 on the inner wall, causing the clamping block 308 to pull the connecting rod 309 while rotating inside the connecting rod 309 and clamping and fixing the outer wall of the wire 7. This allows the clamping block 308 to distinguish and fix the wire 7, preventing electromagnetic coupling interference caused by mixed cable laying, which would affect the signal processing accuracy of the components and cause electromagnetic interference between internal devices to still affect the system. Multiple mounting mechanisms 4 are installed on the inner wall of the cabinet 1. Fixed plates 406 are fixedly connected to the inner wall of the cabinet 1 at equal intervals. When assembling the mounting plate 5, first rotate the bolt 408. The rotation of the bolt 408 drives the connecting frame 405 on its outer wall, causing the connecting frame 405 to drive the locking block 404 to slide outward on the outer wall of the slide rod 407. Then, the mounting block 402 on the outer wall of the mounting plate 5 slides along the outer wall of the slider 403. Then, rotate the bolt 408 in the opposite direction. The rotation of the bolt 408 causes the connecting frame 405 to drive the locking block 404 to move inward, so that the locking block 404 is inserted into the mounting groove 401, forming a stable connection, which facilitates installation and disassembly and improves maintenance efficiency.
