Description

Technical Field

[0001] The utility model relates to the technical field of cabinets, in particular to a marine constant-frequency and constant-voltage cabinet. Background Art

[0002] Green ships have become mainstream ships due to their energy conservation, environmental protection and other characteristics; utilizing the variable-speed unstable power provided by the main diesel engine of the ship to output three-phase alternating current with constant voltage and constant frequency for the load on the ship can greatly improve the efficiency of the main diesel engine of the ship; however, since the marine shaft generator is driven by the main diesel engine of the ship, as the working condition and rotational speed of the main diesel engine change, the frequency and voltage of the shaft generator change accordingly. When other loads require three-phase alternating current with constant frequency and constant voltage, ordinary shaft generators cannot meet the requirements; to solve this problem, the constant-frequency and constant-voltage cabinet matched with the shaft generator can well solve this problem. When the working condition and rotational speed of the main diesel engine change, the constant-frequency and constant-voltage cabinet can ensure that after the alternating current with different frequencies and different voltages output by the shaft generator passes through it, it always outputs three-phase alternating current with constant frequency and constant voltage, which can greatly shorten the operation time of marine auxiliary engines.

[0003] The use of constant-frequency and constant-voltage cabinets plays an important role in the operation of the hull, therefore, positioning inspection and maintenance are required for it. There are many electrical appliances inside the cabinet body, and for the cables inside the cabinet body, wire outlet holes are generally arranged on the back side or the bottom of the cabinet body to lead out the internal cables; when carrying out inspection and maintenance work, when the cables need to be disassembled for maintenance or replacement, it is troublesome to pick out the cables that need to be replaced or inspected from among the numerous cables in the wire outlet hole. Numerous cables are generally crowded together without corresponding classification functions, which brings inconvenience to subsequent inspection and maintenance work.

[0004] Therefore, the utility model provides a marine constant-frequency and constant-voltage cabinet to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a marine constant frequency and constant voltage cabinet, including a cabinet body 1 and a cabinet door 2 located on the front side of the cabinet body 1. Heat dissipation mesh 3 is provided on both sides of the cabinet body 1 near the bottom. A loading cavity 4 is provided on the back side of the cabinet body 1, and mounting slots 5 are symmetrically provided at both ends of the outer cavity opening of the loading cavity 4. Mounting slots 6 are provided in the mounting slots 5. A wire splitting assembly is provided in the loading cavity 4, and the wire splitting assembly is installed and positioned by a set installation structure. That is, the cables are classified and bundled by the wire bundling cavity 705 in the first support body 701 and the second support body 702, which provides convenience for later maintenance. The first support body 701 and the second support body 702 are connected to form a carrier body, which is fitted and inserted into the loading cavity 4. Then, the carrier body is installed and positioned by the installation structure.

[0024] This solution addresses the handling of tail wires in marine constant frequency and constant voltage cabinets by using a separate wiring assembly to categorize and bundle the tail wires, resulting in a clear distribution of the tail wires. Specifically, after the first support body 701 and the second support body 702 are connected, the bundling cavities 705 on both bodies are joined to form bundling grooves. Multiple bundling grooves are provided in the carrier body, allowing for the separate bundling of various cables. This facilitates the retrieval of tail wires by staff during later maintenance work, providing convenience for their operations.

[0025] When sorting and bundling the tail wires, the tail wires are placed in the bundling cavity 705 on the first support 701, and then the second support 702 is placed on top of the first support 701. A docking block 801 is symmetrically fixed at the docking end of the first support 701; a docking slot 901 is symmetrically provided at the docking end of the second support 702. That is, the docking block 801 at the docking end of the first support 701 and the docking slot 901 at the docking end of the second support 702 are inserted into each other. Simultaneously, the docking ends of the first support 701 and the second support 702... The cable bundle cavity 705 is also connected to form a cable bundle circular groove. The cable splitter assembly includes a first support body 701 and a second support body 702. Mounting plates 703 are symmetrically arranged at both ends of the front side of the first support body 701 and the second support body 702. A through groove 704 is provided on the mounting plate 703. Cable bundle cavities 705 are provided in both the first support body 701 and the second support body 702. Auxiliary protrusions 706 are provided on the inner sidewall of the cable bundle cavity 705. The auxiliary protrusions 706 are equidistantly arranged in an arc shape to provide a simple anti-slip function for the cable.

[0026] According to the appendix Figure 2 and attached Figure 4 As shown, the first support body 701 and the second support body 702 are joined together to form a carrier body. The carrier body is fitted and inserted into the loading cavity 4, and then positioned by a mounting structure. The mounting structure includes a mounting screw 1001, an auxiliary knob 1002 fixedly mounted on one end of the mounting screw 1001, a rotating auxiliary protrusion on the side of one end of the auxiliary knob 1002, and an auxiliary pressure plate 1003 fixedly mounted at the connection end between the auxiliary knob 1002 and the mounting screw 1001. That is, when the carrier body formed by the first support body 701 and the second support body 702 is inserted into the loading cavity 4, the mounting plate 703 will also be locked in the mounting slot 5 at the front cavity opening of the loading cavity 4, and the mounting plates on the first support body 701 and the second support body 702 will also be locked in. The mounting plates 703 are spliced ​​together, and the through slots 704 on the two mounting plates 703 are joined to form a mounting hole. When using the mounting structure for installation, the mounting screw is passed through the mounting hole, and then the mounting screw 1001 is rotated by the auxiliary knob 1002, so that the mounting screw 1001 is threaded into the mounting screw groove 6 in the mounting slot 5 until the mounting screw 1001 is tightened. After the mounting screw 1001 is tightened, the auxiliary pressure plate 1003 located at the connection position between the mounting screw 1001 and the auxiliary knob 1002 will exert a squeezing effect on the mounting plate 703. The purpose of setting the rotating auxiliary protrusion at the end side of the auxiliary knob 1002 is to facilitate the operation of the operator when rotating the mounting screw 1001 by the auxiliary knob 1002.
