[0034] The following is combined with Figure 1-4 This application is described in further detail.
[0035] Example 1:
[0036] The embodiment of the present application discloses a power distribution cabinet. Figure 1 The power distribution cabinet includes a cabinet body 1, a cabinet door 3, a mounting frame 2, a shielding plate 4 and a fixing assembly 5, wherein the cabinet body 1 is preferably made of stainless steel to improve the protection effect; the cabinet door 3 is hinged on the cabinet body 1, and the mounting frame 2 is fixed to the cabinet body 1 by welding or bolts, and the space inside the cabinet body 1 is divided into zones by the mounting frame 2, including a general area 11 and an isolation area 12. The general area 11 is used to install general electrical components, and the isolation area 12 is used to install live components or other electrical components that may cause electric shock hazards. The shielding plate 4 is mainly used to shield the isolation area 12, and the fixing parts can fix the shielding plate 4 to the mounting frame 2, thereby installing the shielding plate 4. Through the above structure, the electrical components set in the isolation area 12 can be isolated to prevent the staff from opening the cabinet door 3 or accidentally touching the electrical components when repairing them.
[0037] Reference Figure 1 and Figure 2 In this embodiment, the shielding plate 4 is a rectangular plate corresponding to the space separated by the isolation zone 12. To facilitate observation of the electrical components within the isolation zone 12, the shielding plate 4 is made of a transparent material such as glass or plastic. Preferably, the shielding plate 4 is made of a transparent PVC plastic sheet. The shielding plate 4 is provided with heat dissipation holes 41, and multiple heat dissipation holes 41 are evenly distributed along the surface of the shielding plate 4 to improve the heat dissipation performance of the isolation zone 12. Furthermore, the cabinet door 3 or cabinet body 1 should be provided with air inlet and outlet holes to ensure the heat dissipation performance of the power distribution cabinet.
[0038] Reference Figure 1 and Figure 2In this embodiment, positioning plates 42 are provided on the left and right side walls of the shielding plate 4. The positioning plates 42 are preferably integrally formed with the shielding plate 4. Both positioning plates 42 are perpendicular to the surface of the positioning plates 42 and parallel to the side walls of the mounting frame 2. Therefore, when the positioning plates 42 block the isolation area 12, the positioning plates 42 can abut against the side walls of the mounting frame 2. Optionally, a baffle can be fixed to the side wall of the mounting frame 2. When installing the shielding plate 4, the side wall of the shielding plate 4 can be abutted against the baffle to provide preliminary positioning of the shielding plate 4. This can also improve the stability of the shielding plate 4 when it is fixed to the mounting frame 2.
[0039] In this embodiment, the fixing assembly 5 can be a fixing bolt 51 that can pass through the positioning plate 42 and be threadedly connected to the mounting frame 2. Correspondingly, the positioning plate 42 is pre-opened with an opening for the fixing bolt 51 to pass through, and the side wall of the mounting frame 2 is also pre-opened with a threaded hole for the fixing bolt 51 to be threadedly connected. Therefore, the fixing bolt 51 can be used to removably fix the positioning plate 42 to the mounting frame 2. A plurality of fixing bolts 51 are arranged at intervals along the length of the positioning plate 42, and the fixing bolts 51 are respectively provided on the positioning plate 42 on both sides of the shielding plate 4 to improve the stability of the shielding plate 4 during installation.
[0040] The power distribution cabinet of the present embodiment is implemented as follows: a mounting frame 2 is used to separate the interior of the cabinet 1 into a general area 11 and an isolated area 12. A shielding plate 4 is provided outside the isolated area 12 to provide shielding, effectively isolating live components and improving operational safety. Furthermore, the shielding plate 4 is detachably secured to the mounting frame 2 by means of a positioning plate 42 and fixed bolts 51. This allows for removal of the shielding plate 4 to allow for inspection and maintenance of electrical components within the isolated area 12.
[0041] Example 2:
[0042] Based on the embodiment 1, this embodiment provides a different design of the fixing component 5. Figure 3 and Figure 4When the fixing rods 52 on both sides of the shielding plate 4 slide out of the side walls of the mounting frame 2 and pass through the positioning plate 42, the shielding plate 4 can be fixed on the mounting frame 2.
[0043] Reference Figure 3 and Figure 4 Optionally, a baffle can be fixed on the mounting frame 2. When installing the shielding plate 4, the mounting plate can be placed against the shielding plate 4 first. At this time, the sliding groove on the side wall of the mounting frame 2 can be aligned with the opening on the positioning plate 42, making it convenient for the fixing rod 52 to pass through the sliding groove and the opening.
[0044] Reference Figure 3 and Figure 4 In this embodiment, the fixing assembly 5 further includes a driving member 54 for driving the connecting rod 53 to slide, and a limiting member 55 for limiting the sliding of the connecting rod 53. The driving member 54 is a driving rod fixed to the side wall of the connecting rod 53, and a clearance groove 21 for the driving rod to slide is formed on the side wall of the mounting frame 2. The clearance groove 21 extends along the sliding direction of the fixing rod 52. This design makes it easy for the operator to drive the connecting rod 53 to slide through the driving rod.
[0045] Reference Figure 3 and Figure 4 In this embodiment, the limiting member 55 is a limiting rod hinged to the drive rod, which can rotate up and down relative to the drive rod. The mounting frame 2 is provided with a limiting slot 22 for the limiting rod to engage. The limiting slot 22 is preferably located below the clearance slot 21. When the fixed rod 52 slides through the positioning plate 42, the limiting rod can rotate downward relative to the drive rod and engage within the limiting slot 22, thereby limiting the sliding of the drive rod, that is, limiting the sliding of the connecting rod 53 and the fixed rod 52. At this time, there is a gap between the end surface of the limiting rod and the sidewall of the limiting slot 22, making it easy to rotate the limiting rod from within the limiting slot 22.
[0046] Furthermore, the mounting frame 2 is provided with a positioning slot 23 for the limit rod to engage with. The positioning slot 23 is connected to the end of the clearance slot 21 away from the shielding plate 4. When installing the shielding plate 4, the fixing rod 52 can be first slid toward the positioning slot 23 so that the fixing rod 52 is received in the mounting frame 2. Then, the limit rod is rotated and engaged into the positioning slot 23 to temporarily fix the limit rod. The positioning slot 23 is arranged parallel to the limit slot 22 and is respectively located at both ends of the clearance slot 21. Furthermore, a clamping block 6 is provided on the side wall of the limit rod. The clamping block 6 is made of an elastic material such as rubber. The clamping block 6 can be interference-engaged with the limit member 55 in the limit slot 22 or in the positioning slot 23, thereby preventing the limit rod from falling out of the lower slot or the positioning slot 23, thereby improving the stability of the structure.
[0047] 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.
