[0002] A marine power conversion control box is an automatic power switching device designed specifically for ships. Its primary function is to automatically or manually switch the load to a backup power source when the primary power source fails or requires maintenance, ensuring continuous and stable power supply to the ship's electrical system. This control box is typically highly reliable and intelligent, ensuring the normal operation of critical ship equipment in complex and changing environments.
[0003] In terms of operation, the ship's power conversion control box can be switched to automatic mode by a key or button. In this mode, the system can automatically detect the power status and switch to the backup power supply without interruption when needed. In manual mode, the operator needs to use the handle to switch the power supply.
[0004] The installation position of the power switch installed inside the existing power conversion control box is fixed. Therefore, in an environment with narrow space or complex layout, the fixed installation position may make the power switch inconvenient to operate and maintain.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0024] The utility model provides Figure 1-5 A ship-mounted power conversion control box is shown, comprising a control box 1. The control box 1 serves as the main body of the power conversion control box and provides a structure for protecting and housing internal components. The control box 1 has sufficient strength and stability to cope with the harsh environment faced by ships. An input terminal 3 is fixedly mounted above the inner wall of the control box 1. The input terminal 3 is used to connect the main power supply and the backup power supply, enabling the control box to detect the power status and achieve automatic or manual switching. A power switch 2 is provided below the inner wall of the control box 1. The power switch 2 plays a key role in the power switching process. Through a sliding connection with a guide block 7, the power switch 2 can be more flexible during operation, avoiding the problem of inconvenience in operation in a narrow space. Guide blocks 7 are fixedly mounted below the inner wall of the control box 1 and on both sides of the back of the power switch 2. The guide blocks 7 help the power switch 2 maintain stability during operation and reduce friction. Slide grooves 21 are provided on both sides of the back of the power switch 2. The back of the power switch 2 is slidably connected to the guide blocks 7 via the slide grooves 21.
[0025] Support bars 4 are fixedly installed at both ends of the power switch 2. One end of the two support bars 4 does not contact the inner wall of one side of the control box 1. The support bars 4 and the spring 6 help the power switch 2 to remain stable during operation. The bottom of the two support bars 4 is fixedly installed with a spring 6. The bottom of the spring 6 is fixedly connected to the bottom of the control box 1. The two support bars 4 are provided with a through hole 41 at a position corresponding to the vertical center of the spring 6.
[0026] Furthermore, in the above technical solution, screws 5 are vertically inserted into the through holes 41 of the two support bars 4, the bottoms of the two screws 5 are fixedly connected to the bottom of the control box 1, and the upper ends of the two screws 5 are threadedly sleeved with nuts 51, which are located above the support bars 4.
[0027] Furthermore, in the above technical solution, a box door 9 is installed on the front of the control box 1 through a hinge, and warning lights 92 are fixedly installed on both sides of the lower front of the box door 9 and at positions corresponding to the bottom of the power switch 2. A support base 91 is fixedly installed on the lower back of the box door 9 and at positions corresponding to the two warning lights 92. The electrical connection between the warning light 92 and the support base 91 ensures that it can work normally when needed.
[0028] Furthermore, in the above technical solution, the support base 91 is made of metal material, the warning light 92 is electrically connected to the support base 91 through a wire, the upper surface position height of the support base 91 is the same as the bottom height of the power switch 2, and the length of the support base 91 is equal to the length from the bottom of the power switch 2 to the back of the box door 9. The support base 91 can support the bottom of the power switch 2.
[0029] Furthermore, in the above technical solution, threaded holes are provided above and below the front of the guide block 7, and limit bars 8 are provided on the top and bottom of the power switch 2. The two ends of the limit bars 8 are connected to the threaded holes above and below the front of the two guide blocks 7 by bolts. The limit bars 8 ensure that the installed position of the power switch 2 is fixed.
[0030] The working process of the ship power conversion control box provided by the utility model when in use is as follows:
[0031] The control box 1 should be installed in a suitable position on the ship to ensure sufficient operating space. Connect the main power supply and backup power supply to the input terminal 3. As needed, the control box can be switched to automatic or manual mode by a key or button. In the automatic mode, the system will automatically detect the power status and switch to the backup power supply without interruption when the main power fails. In the manual mode, the operator needs to switch the power supply through the handle. Regularly check and maintain the circuit breaker 2 and other internal components to ensure their normal operation.
[0032] When installing the power switch 2 or wiring the power switch 2, if the distance between the power switch 2 and the input terminal 3 affects the wiring, first open the box door 9, then remove the limit bar 8 under the guide block 7, and then adjust the nut 51 on the screw rod 5, that is, the nut 51 moves downward along the screw rod 5, so that the nut 51 resists the support bar 4 and descends, and squeezes the spring 6, thereby lowering the position height of the power switch 2, so as to facilitate the wiring between the power switch 2 and the input terminal 3. When the wiring is completed, turn the nut 51 to restore it to its original position, and then install the limit bar 8 under the guide block 7 to complete the position adjustment of the power switch 2.
[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
