Sliding installation structure of marine electronic control module

Abstract

The invention discloses a marine electronic control module slide type installation structure. The structure comprises an electronic control module, not less than two module mounting plates which enable the electronic control module to be disposed in a cabinet, and guide rails the number of which is the same as the number of the module mounting plates; and the guide rails are connected with the module mounting plates, and the guide rails are at least respectively disposed at the upper part and the lower part of the electronic control module. The electronic control module further comprises a bottom plate, the bottom plate is connected with the module mounting plates through the guide rails, is disposed between the guide rails at the upper and lower parts of the electronic control module, and can slide along the guide rails. A locking mechanism is disposed at one end of module mounting plates, and, after the electronic control module is pushed into the cabinet through the guide rails, the electronic control module is tightly locked through the locking mechanism. The structure can enable the electronic control module to be conveniently pulled out of the cabinet, component and part operation and wiring are performed, operation is convenient, a space is wide, early-stage installation and later-stage maintenance of components and parts are convenient, the volume of the cabinet can also be reduced, cost of the cabinet is lowered, and safety and reliability of the electronic control module are further improved.

Description

technical field [0001] The invention relates to the field of industrial electrical equipment, in particular to a sliding installation structure of a marine electric control module applied to a cabinet of a frequency converter on a ship. Background technique [0002] Ships operate in the sea. Under normal circumstances, due to the influence of propellers, wind and waves, etc., the ship will experience strong vibration and large swing. In the marine electric control cabinet, the high and low voltage components are the key components of the circuit. The components are connected with many cables. If they are not properly arranged, the internal structure of the cabinet will become complicated and occupy more space. space. In addition, the harsh vibration conditions on the ship may cause the components to resonate, affecting the normal operation of the components, and even loosening of the mounting screws, which seriously affects the normal operation of the cabinet. At the same ...

AI Technical Summary

Problems solved by technology

[0005] (1) In the existing cabinet body, the layout of electrical components and wire slots is scattered, which cannot effectively use the internal space of the cabinet body, making the structure inside the cabinet complex. In order to consider the layout of various components, it is often necessary to repeatedly adjust the space inside the cabinet , to meet the electrical and structural requirements, so that the space occupation is large, which is not conducive to the simplification of the overall structure and volume;

[0006] (2) The existing cabinet adopts a scattered component layout. During the later maintenance, the staff needs to look for components in the cabinet. Often, in order to remove one component, other components need to be removed, which greatly reduces the work efficiency;

[0007] (3) The internal wiring of the existing cabinet body is complicated, and the wiring harness needs to bypass the interference of the structure. It often needs to be routed repeatedly left and right, the layout is complicated, and the amount of wire is large, which makes the work efficiency low and the cost of wire is high;

[0008] (4) In the existing technical scheme, the components are installed on the fixed guide rail, and the fixed guide rail and the cabinet are connected by screws. In this way, the components are subject to strong vibration of the cabinet, and the anti-vibration ability is poor, so it is not applicable In the vibration and sway environment of the ship;

[0009] (5) The guide rail structure of the existing cabinet body lacks effective fixing at the selected position, and the ship cabinet body requires maintenance under long-term vibration and swaying, and the guide rail structure without position fixing function is difficult to maintain in this environment , if the ship encounters strong winds and waves during maintenance, it will increase the danger of maintenance work;

[0010] (6) When the existing cabinet structure is being maintained, the ship is frequently impacted by sea waves, and the cabinet is subjected to different degrees of impact, which causes the cabinet to sway violently. The guide rail structure of the existing cabinet lacks an effective limit structure. This makes the structure easy to fall out of the guide rail, and operation and maintenance are quite risky
