[0002] Busbar trunking is a busbar system consisting of a metal outer shell, a cover plate, and partition plates. Multiple partition plates can be installed inside the busbar trunking to divide it into several enclosed spaces. However, existing enclosed busbar trunking systems use rubber strips for sealing between the cover plate and the enclosure, but these rubber strips age over time, causing gaps to appear in the seal. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength fireproof dense busbar trunking insulation partition assembly, comprising a busbar trunking frame, heat dissipation plates fixedly connected to the outer side walls of both sides of the busbar trunking frame, at least three isolation plates fixedly connected inside the busbar trunking frame, a sealing cover provided at the upper end of the busbar trunking frame, and multiple sealing protrusions fixedly connected to the lower end of the sealing cover. The sealing cover and the isolation plates cooperate to divide the internal space of the busbar trunking frame into several mutually isolated sealed spaces. Connecting pieces and elastic pieces are fixedly connected to both sides of the isolation plates. The elastic pieces are located at the lower end of the connecting pieces. A sealing strip is fixedly connected to the upper end of the connecting pieces to ensure sealing. A compression protrusion for compensating for wear is fixedly connected to the upper end of the elastic pieces. At least one deceleration protrusion is fixedly connected to both sides of the isolation plates. The side end of the deceleration protrusion has an arc-shaped structure. Snap-fit ​​protrusions are fixedly connected to both sides of the sealing cover. Snap-fit ​​grooves are provided on the side ends of the snap-fit ​​protrusions. An installation piece is fixedly connected to the side end of the busbar trunking frame.

[0005] Preferably, the insulating plate has sealing protrusions on both sides, and the two sealing protrusions are used to position and insert the insulating plate. The side of the sealing protrusion away from the insulating plate has an arc-shaped structure.

[0006] Preferably, the sidewalls on both sides of the sealing strip are arc-shaped, the lower sidewall of the sealing strip is horizontal, and the upper end of the sealing strip abuts against the lower inner wall of the sealing cap.

[0007] Preferably, the lower end sidewall of the sealing strip is provided with a positioning groove, the elastic sheet has an arc-shaped structure, and the extrusion protrusion is engaged in the positioning groove.

[0008] Preferably, the width of the deceleration protrusion is greater than half the distance between the two partition plates, and the deceleration protrusions on the sides of the two partition plates are staggered.

Detailed Implementation

[0017] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a high-strength fireproof dense busbar trunking insulation partition assembly, including a busbar trunking frame 1. Heat dissipation plates 5 are fixedly connected to the outer walls of both sides of the busbar trunking frame 1. At least three isolation plates 3 are fixedly connected inside the busbar trunking frame 1. A sealing cover 2 is provided at the upper end of the busbar trunking frame 1, and multiple sealing protrusions 10 are fixedly connected to the lower end of the sealing cover 2. The sealing cover 2 and the isolation plates 3 cooperate to divide the internal space of the busbar trunking frame 1 into several mutually isolated sealed spaces. Connecting pieces 11 and elastic pieces 13 are fixedly connected to both sides of the isolation plates 3. The elastic pieces 13 are located at... The lower end of the connecting piece 11 and the upper end of the connecting piece 11 are fixedly connected to a sealing strip 12 to ensure sealing. The upper end of the elastic piece 13 is fixedly connected to a compression protrusion 14 to compensate for wear. At least one deceleration protrusion 9 is fixedly connected to both sides of the isolation plate 3. The side end of the deceleration protrusion 9 has an arc-shaped structure. The two sides of the sealing cover 2 are fixedly connected to a snap-fit ​​protrusion 6. The side end of the snap-fit ​​protrusion 6 is provided with a snap-fit ​​groove 7. The side end of the busbar frame 1 is fixedly connected to an installation piece 8. The isolation plate 3 divides the internal space of the busbar frame 1 into multiple unconnected spaces.

[0019] Both sides of the isolation plate 3 are provided with sealing protrusions 10. The two sealing protrusions 10 are used to position and insert the isolation plate 3. The two sealing protrusions 10 cooperate with each other to position and insert with the isolation plate 3. The side of the sealing protrusion 10 away from the isolation plate 3 has an arc-shaped structure, which facilitates the compression of the sealing strip 12, so that the sealing strip 12 abuts against the sealing cover 2.

[0020] Both sides of the sealing strip 12 have an arc-shaped structure, and the lower side wall of the sealing strip 12 has a horizontal structure. The upper end of the sealing strip 12 abuts against the lower inner wall of the sealing cover 2. The lower side wall of the sealing strip 12 is provided with a positioning groove 15. The elastic sheet 13 has an arc-shaped structure, and the extrusion protrusion 14 is engaged in the positioning groove 15. The extrusion protrusion 14 extrudes the sealing strip 12, so that the upper end of the sealing strip 12 always abuts against the sealing cover 2. Therefore, when the sealing strip 12 ages, it can compensate for the aged parts and ensure the sealing performance.

[0021] The width of the deceleration protrusion 9 is greater than half the distance between the two isolation plates 3. The deceleration protrusions 9 on the sides of the two isolation plates 3 are staggered. The deceleration protrusions 9 can block the space between the two isolation plates 3 to a certain extent, preventing the fire from spreading rapidly along the internal isolation space after the internal cable catches fire, thus increasing safety.

[0022] The side end of the snap-fit ​​protrusion 6 is an inclined surface, and the snap-fit ​​groove 7 is located on the inclined surface. The mounting plate 8 has an arc-shaped structure and is an elastic iron plate. The mounting plate 8 and the snap-fit ​​groove 7 snap together, so that the sealing cover 2 and the busbar frame 1 can be installed without bolts, making installation and disassembly more convenient and facilitating subsequent cable layout.

[0023] The heat sink 5 has multiple heat dissipation fins on its side. A heat-conducting column 4 is fixedly connected in the middle of the busbar frame 1. The two ends of the heat-conducting column 4 pass through the busbar frame 1 and are connected to the heat sink 5. The heat-conducting column can conduct heat in the internal isolation space formed by the insulation plate 3, so that the heat reaches the heat sink 5 and is dissipated, thus preventing heat from accumulating inside.

[0024] Although embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the usage of the embodiments of the present invention, and is not intended to limit the present invention in any way. Those skilled in the art will understand that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
