[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of 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 some, not all, of the embodiments of this utility model.

[0023] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] like Figure 1 As shown, this embodiment proposes a dustproof and liquid-proof sealing structure for a power distribution cabinet, including a distribution cabinet body 1, a dustproof and liquid-proof mechanism 2 for preventing dust and liquid intrusion on the distribution cabinet body 1, and a fixing component 3 for fixing equipment inside the distribution cabinet body 1.

[0027] like Figure 4As shown, the dustproof and liquid-proof mechanism 2 includes an extended door frame 201 fixedly connected to the main body of the distribution cabinet 1. The extended door frame 201 can increase the contact area between the outer door 4 and the main body of the distribution cabinet 1, and improve the sealing performance. An inverted eave 202 is welded on the side wall of the extended door frame 201. The inverted eave 202 guides liquid and dust to slide down its surface through its inward protruding structure, avoiding direct contact with the sealed area of ​​the main body of the distribution cabinet 1. A dust and liquid collection groove 203 is provided on the side wall of the extended door frame 201 to collect liquid or dust blocked by the inverted eave 202, preventing it from accumulating and seeping into the cabinet, and also serving as a diversion and temporary storage function. When liquids and dust enter the cabinet, the anti-reflective vent 202 guides the liquids and dust to slide down its surface and enter the dust and liquid collection groove 203. The dust will be temporarily stored in the dust and liquid collection groove 203, and the liquid will flow out of the surface of the power distribution cabinet body 1 through the dust and liquid collection groove 203, taking away some of the dust.

[0028] like Figure 3 As shown, the fixing component 3 includes a support plate 301 fixedly connected to the inner wall of the distribution cabinet body 1, providing rigid support for the distribution cabinet body 1 to ensure structural stability. It also positions the wiring troughs 302. The wiring troughs 302 are fixedly connected to the side wall of the support plate 301 and are bolted to the inner wall of the distribution cabinet body 1. There are six wiring troughs 302, arranged in pairs along the height of the distribution cabinet body 1. The wiring troughs 302 ensure the stability of the wiring structure and prevent loosening of electrical components due to vibration or external forces. In use, the support plate 301 improves the structural stability of the distribution cabinet body 1, and the six wiring troughs 302, arranged in pairs along the height of the cabinet, allow for the separate fixing of strong and weak current lines and lines with different functions, avoiding cross-interference.

[0029] like Figure 1 As shown, an outer door 4 is hinged to the main body 1 of the distribution cabinet. A foam strip 5 is fixedly connected to the inner wall of the outer door 4. When the outer door 4 is closed, the foam strip 5 adheres to the anti-reflective surface 202, causing deformation and providing good sealing. A reinforcing rib 6 is fixedly connected to the inner wall of the outer door 4 to enhance its overall rigidity. In use, when the outer door 4 is closed, the foam strip 5 adheres to the anti-reflective surface 202 and deforms, filling the gap and further improving dust and liquid protection. At the same time, it buffers the impact force when closing the outer door 4. The reinforcing rib 6 enhances the overall strength of the cabinet door, prevents deformation due to external forces, and ensures the long-term effectiveness of the sealing structure.

[0030] like Figure 1 As shown, two lifting rings 7 are fixedly connected to the top of the distribution cabinet body 1, and they are arranged diagonally. During installation, the lifting rings 7 provide lifting points to ensure the cabinet is balanced during transportation and installation, and to avoid displacement of internal components or structural damage due to tilting.

[0031] like Figure 4 As shown, the main body 1, outer door frame 201, and inverted eaves 202 of the distribution cabinet are made of cold-rolled steel sheet. These components are formed by CNC punching and sheet metal bending. The cold-rolled steel sheet, through a cold-working hardening process, has high tensile and yield strength, capable of withstanding the weight of the internal equipment and external impacts, preventing structural deformation that could lead to sealing failure. During use, the CNC punching and sheet metal bending process results in minimal machining errors for the main body 1, outer door frame 201, and inverted eaves 202, meeting the precision requirements of the dustproof and liquid-proof mechanism 2.

[0032] like Figure 1 As shown, the inner wall of the distribution cabinet body 1 is provided with heat dissipation holes 8, and the number of heat dissipation holes 8 is several. When the distribution cabinet is working, the air convection inside and outside the cabinet is realized through multiple heat dissipation holes 8, which reduces the operating temperature of the internal equipment and prevents the insulation performance from deteriorating or the components from aging due to overheating.

[0033] like Figure 4 As shown, the surfaces of the distribution cabinet body 1, the outer door frame 201, and the inverted eaves 202 are coated with an anti-rust coating made of epoxy resin paint. During use, the anti-rust coating covers the surfaces of the distribution cabinet body 1, the outer door frame 201, and the inverted eaves 202, forming a dense protective film that isolates oxygen and moisture, prevents oxidation and rusting of the cold-rolled steel substrate, extends the cabinet's service life, and reduces maintenance costs.

[0034] Specifically, in use, the dustproof and liquid-proof sealing structure of this power distribution cabinet improves the structural stability of the cabinet body 1 by using the support plate 301. Simultaneously, the six cable trays 302, distributed in pairs along the height of the cabinet, allow for the separate fixing of strong and weak current lines and lines with different functions, avoiding cross-interference (e.g., ...). Figure 3 As shown), when liquid and dust enter the cabinet, the anti-reflective fin 202 guides the liquid and dust to slide down its surface and enter the dust and liquid collection groove 203. The dust will be temporarily stored in the dust and liquid collection groove 203, and the liquid will flow out of the surface of the distribution cabinet body 1 through the dust and liquid collection groove 203, carrying away some of the dust (such as...). Figure 4 As shown), when the cabinet door is closed, the foam strip 5 adheres to the flange 202 and deforms, filling the gap and further improving dustproof and liquidproof performance. Simultaneously, it buffers the impact force when the cabinet door 4 is closed. The reinforcing rib 6 enhances the overall strength of the cabinet door, preventing deformation due to external forces and ensuring the long-term effectiveness of the sealing structure (e.g., ...). Figure 1 (As shown).

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
