DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] The utility model provides the following preferred embodiments:

[0034] A plurality of mounting seats 12 are fixed equidistantly inside the cabinet 11, each module unit 17 is mounted on one side of an L-shaped mounting plate 16, and a mounting mechanism is provided between each L-shaped mounting plate 16 and a mounting seat 12, and the L-shaped mounting plate 16 is used to mount the module unit 17;

[0035] Each mounting mechanism includes a mounting hole 13, a plug-in block 15, two positioning components and two unlocking components. The mounting hole 13 is opened at the top of the mounting seat 12. The plug-in block 15 is fixed below the L-shaped mounting plate 16. The bottom end of the plug-in block 15 is inserted into the interior of the mounting hole 13. The two positioning components are symmetrically arranged on both sides of the plug-in block 15. Each unlocking component is located on one side of a positioning component.

[0036] When installing the module unit 17, the plug-in block 15 is inserted into the inside of the mounting hole 13, and the positioning assembly is used to position the plug-in block 15, so that the module unit 17 on the L-shaped mounting plate 16 can be installed and positioned. At the same time, the unlocking assembly is used to release the positioning of the plug-in block 15, which is convenient for disassembly of the module unit 17, and convenient for quick installation and disassembly of each module unit 17, so that the assembly process of the frequency converter cabinet is relatively simple and convenient, the efficiency of installation and disassembly of the frequency converter cabinet is improved, and the maintenance of each module unit 17 is further facilitated;

[0037] A standardized cabinet is formed through modular design, which improves the stability of the product and increases the convenience of installation and maintenance. At the same time, the modular combination method makes the layout inside the cabinet 11 more concise and convenient for maintenance; at the same time, while achieving a higher protection level, the space volume of the whole cabinet is small, which can be applied to different places of the ship, and the installation position is more extensive and convenient, while increasing the utilization space of relevant places of the ship.

[0038] The fire extinguishing mechanism includes an atomizing nozzle 32, a smoke sensor 33, a storage cylinder 30 and an extrusion assembly. The storage cylinder 30 is installed at the top of the cabinet 11, the atomizing nozzle 32 is installed at the top of the inner cavity of the cabinet 11, the atomizing nozzle 32 and the storage cylinder 30 are connected by a pipe 31, the smoke sensor 33 is installed at the top of the inner cavity of the cabinet 11 and is located on one side of the atomizing nozzle 32, and the extrusion assembly is located on one side of the storage cylinder 30;

[0039] By setting up a smoke sensor 33, when the smoke sensor 33 detects that smoke is generated inside the cabinet 11, the signal can be sent to the controller, and the controller can control the cylinder 36 to work, and the fire extinguishing agent stored in the storage tube 30 is sprayed out through the atomizing nozzle 32, so as to achieve fire extinguishing treatment inside the cabinet 11, which is beneficial to improve the safety factor of the frequency converter cabinet.

[0040] like Figure 1-Figure 6 As shown, each positioning assembly includes a side plate 14, a positioning rod 19 and a spring 20. The side plate 14 is fixed to the inside of the mounting seat 12. The positioning rod 19 is slidably arranged on the side plate 14. A positioning hole 18 matching with the positioning rod 19 is opened on the side of the plug-in block 15. The end of the positioning rod 19 is inserted into the inside of the positioning hole 18. The spring 20 is fixed to the side of the positioning rod 19 away from the mounting hole 13. The other end of the spring 20 is fixedly connected to the inner wall of the mounting seat 12.

[0041] When the plug-in block 15 is inserted into the mounting hole 13, the plug-in block 15 first presses the positioning rod 19. Since both sides of the bottom end of the plug-in block 15 and the top of the positioning rod 19 close to the plug-in block 15 are provided with bevels, when the plug-in block 15 moves downward, the positioning rod 19 can move horizontally toward the side away from the plug-in block 15. At this time, the spring 20 is compressed. When the plug-in block 15 is completely moved into the mounting hole 13, the positioning hole 18 on the plug-in block 15 can move to the position of the positioning rod 19. Under the action of the spring 20, the positioning rod 19 can be driven to reset, so that the positioning rod 19 can be inserted into the positioning hole 18, thereby realizing the positioning of the plug-in block 15, and then realizing the positioning of the module unit 17.

[0042] like Figure 1-Figure 6 As shown, guide rods 21 are fixed on both sides of the spring 20, and the other end of each guide rod 21 passes through the positioning rod 19 and is slidably connected to the positioning rod 19. The sliding connection between the guide rod 21 and the positioning rod 19 can be used to guide the positioning rod 19 when it moves, thereby increasing stability.

[0043] like Figure 1-Figure 6As shown, each unlocking assembly includes a hinge rod 24, a push rod 28, a pinch plate 29 and two swing rods 23, and the hinge rod 24 is rotatably arranged inside the mounting seat 12. The two swing rods 23 are symmetrically fixed to the surface of the hinge rod 24, and a first strip groove 25 is opened on the side of each swing rod 23 close to the positioning rod 19, and a first support rod 22 is slidably connected inside each first strip groove 25, and each first support rod 22 is fixedly connected to the positioning rod 19;

[0044] A second strip groove 27 is formed on the other side of each swing rod 23, and a second support rod 26 is slidably connected inside the two second strip grooves 27. One side of a push rod 28 is fixedly connected to the second support rod 26, and the other end of the push rod 28 passes through the mounting seat 12 and is fixedly connected to the pinching plate 29.

[0045] When it is necessary to release the positioning of the plug-in block 15, the two pinching plates 29 are pinched to make the two pinching plates 29 approach each other. At this time, the pinching plates 29 can drive the two push rods 28 to move on the mounting seat 12 and approach each other. Since the second support rod 26 slides inside the second strip groove 27, and the second support rod 26 and the push rod 28 are fixedly connected, when the push rod 28 moves, it can drive the second support rod 26 to move. When the second support rod 26 moves, it can drive the swing rod 23 to rotate around the axis of the hinge rod 24. Since the first support rod 22 slides inside the first strip groove 25, when the swing rod 23 rotates, it can drive the first support rod 22 to move toward the side away from the plug-in block 15. When the first support rod 22 moves, it can drive the positioning rod 19 to move, so that the positioning rod 19 can be moved out of the positioning hole 18, thereby unlocking the plug-in block 15. At this time, the plug-in block 15 is taken out from the inside of the mounting hole 13, and the module unit 17 can be disassembled to facilitate subsequent maintenance work.

[0046] like Figure 1-Figure 6 As shown, both sides of the bottom end of the plug-in block 15 and the top of the end of the positioning rod 19 close to the plug-in block 15 are provided with bevels. The bevel setting facilitates the insertion of the plug-in block 15 into the interior of the mounting hole 13, and also facilitates the lateral movement of the positioning rod 19 while the plug-in block 15 is inserted.

[0047] like Figure 1-Figure 6 As shown, the extrusion assembly includes a cylinder 36, a moving plate 34 and a pusher 35. The pusher 35 is slidably disposed inside the storage cylinder 30. One end of the pusher 35 away from the pipe 31 passes through the storage cylinder 30 and is fixedly connected to the moving plate 34. The cylinder 36 is fixedly installed on the top of the cabinet 11, and the output end of the cylinder 36 is fixedly connected to the moving plate 34. The pusher 35 is composed of a piston and a moving rod. The piston slides inside the cabinet 11, one end of the moving rod is fixedly connected to the piston, and the other end of the moving rod is connected to the moving plate 34.

[0048] Specifically, the smoke sensor 33 is electrically connected to the controller, and the cylinder 36 is electrically connected to the controller;

[0049] When the smoke sensor 33 detects that smoke is generated inside the cabinet 11, the signal can be sent to the controller, and the controller can control the cylinder 36 to work. The cylinder 36 drives the movable plate 34 to move, and the movable plate 34 drives the pusher 35 to move. The fire extinguishing agent located inside the storage tube 30 can be sprayed out through the atomizing nozzle 32, thereby realizing fire extinguishing treatment inside the cabinet 11, which is beneficial to improving the safety factor of the frequency conversion cabinet.

[0050] The beneficial effects of the present invention are specifically embodied in that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
