Description

Technical Field

[0001] This utility model relates to a cabinet structure for a ship's electrical distribution cabinet. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations. They have different technical performance, equipment, and structural types according to different usage requirements. The power distribution system is the core equipment for ship operation. The power distribution cabinet is the power hub on the ship and is the foundation for the safe and reliable operation of the ship. The power distribution cabinet generates a lot of heat during operation. However, traditional power distribution cabinets mostly rely on natural heat dissipation, which is not very effective. This causes a lot of heat to accumulate inside the power distribution cabinet, resulting in a continuous rise in the internal temperature of the power distribution cabinet. This can easily cause the equipment inside the emergency power distribution cabinet to malfunction due to overheating, affecting the normal operation of the ship. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a shipboard power distribution cabinet structure that is reasonably designed, easy to install and transport, has good heat dissipation, high overall structural strength, and can be lifted in an emergency when the ground is wet to avoid safety accidents.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] like Figure 1-4 As shown, a shipboard power distribution cabinet structure includes a cabinet 1, a lifting mechanism 2 for driving the cabinet to rise and fall, a base plate 3, support plates 4 on the left and right sides of the base plate, a back plate 5 between the rear sides of the two support plates, a top plate 6 between the top sides of the two support plates, a cabinet door 7 between the front sides of the two support plates, a heat dissipation plate structure 8 on the back plate, and a fan assembly 9 on the support plates. In use, the fan assembly exhausts the hot air inside the cabinet, and the heat dissipation plate conducts heat to further dissipate the heat from the rear, resulting in good heat dissipation.

[0020] In this embodiment, for ease of on-site installation, the support plate includes a vertically arranged front plate 10 and a vertically arranged rear plate 11. The front and rear plates are provided with folded ears 12 around their edges. However, for ease of installation, the front plate may not have folded ears. The rear folded ears of the front plate are attached to the front folded ears of the rear plate and connected by several bolts. Alternatively, the bolt connection in this device can also use existing methods such as rivets or welding, as long as it achieves fixation. The bottom folded ears of the front and rear plates are fixed to the base plate by several bolts, and the top folded ears of the front and rear plates are fixed to the top plate by several bolts. The rear folded ears of the two rear plates are fixed to the side edges of the back plate by several bolts. The back plate has folded ears at its top and bottom. The top folded ear of the back plate is fixed to the top plate by several bolts, and the bottom folded ear of the back plate is fixed to the base plate by several bolts. The cabinet door is hinged between the top and bottom plates. The folded ears achieve the overall form of the device, making on-site installation convenient.

[0021] In this embodiment, to achieve internal partitioning of the cabinet, two horizontal partition plates 13 are arranged between the two front panels from top to bottom. The partition plates have folded lugs on their left and right sides and rear side. The folded lugs on the left and right sides of the partition plates are bolted to the front panels on the same side. Two L-shaped support plates 14 are arranged between the two rear panels from top to bottom. The upper L-shaped support plate has its vertical portion on top and its horizontal portion on the bottom, while the lower L-shaped support plate has its horizontal portion on top and its vertical portion on the bottom. Folded lugs are arranged on both sides of the horizontal portion of the L-shaped support plates. The folded lugs of the L-shaped support plates are bolted to the rear panels on the same side. The left and right sides of the vertical portion of the L-shaped support plates are bolted to the folded lugs on the front of the rear panels. The rear folded lugs of the partition plates are fixed to the vertical portion of the corresponding L-shaped support plates. Through the cooperation of the partition plates and the L-shaped support plates, internal partitioning of the cabinet is achieved on the one hand, and the connection strength of the overall structure is enhanced on the other.

[0022] In this embodiment, in order to achieve heat conduction, the heat dissipation plate structure includes a vertically arranged heat dissipation contact plate 15, and several horizontal heat conduction plates 16 are arranged at intervals from top to bottom on the rear side of the heat dissipation contact plate. The four edges of the heat dissipation contact plate are screwed to the inner wall of the back plate. The back plate has a clearance opening corresponding to the heat conduction plates. The heat dissipation plate structure corresponds to the vertical part of the L-shaped support plate. Both the heat dissipation contact plate and the heat conduction plates are made of thermally conductive materials. The heat dissipation contact plate and the heat conduction plates realize the rapid dissipation of heat inside the equipment.

[0023] In this embodiment, in order to further dissipate heat, a plurality of heat dissipation holes 17 are provided on both the front plate and the rear plate. A fan mounting hole 18 is provided on one of the front plates corresponding to the partition layer separated by the partition plate. That is, a fan mounting hole is provided on each front plate corresponding to each partition layer. The fan assembly is installed in the fan mounting hole and is used to exhaust hot air to the outside.

[0024] In this embodiment, to further isolate the cabinet from the outside world, the lifting mechanism includes an isolation cover 19 covering the cabinet. The isolation cover has several ventilation holes 20. To facilitate quick lifting of the cabinet off the ground in an emergency, synchronously moving lifting screws 21 are installed on the left and right sides of the isolation cover. The upper ends of the two lifting screws rotate synchronously via a belt and pulley. One of the lifting screws is driven by a motor installed at the top. Sliding blocks 22 are provided on both sides of the top and bottom plates corresponding to the lifting screws. Screw holes are provided on the sliding blocks corresponding to the lifting screws. In addition, to assist in lifting the cabinet, vertical guide rails 23 parallel to the screw holes are installed on the left and right sides of the isolation cover. Guide grooves are provided on both sides of the top and bottom plates corresponding to the vertical guide rails. Of course, to achieve lifting in an emergency, sufficient wire length needs to be reserved in the area inside the isolation cover to prevent breakage during lifting. At the same time, a door can be provided on the front or back of the isolation cover.
