[0042] The following further elaborates in detail on the specific implementation manners of the present utility model in conjunction with the attached drawings.

[0043] As Figure 1-2 shown, a marine discharge cabinet of the present utility model includes a cabinet body 1, a filter assembly 3, ventilation louvers 4, and copper foil 7;

[0044] The cabinet body 1 includes a partition 13, a high-temperature compartment 11, and a normal-temperature compartment 12. The partition 13 is located between the high-temperature compartment 11 and the normal-temperature compartment 12; the partition 13 is provided with a perforated wiring board 131 for connecting the cables between the high-temperature compartment 11 and the normal-temperature compartment 12.

[0045] As Figure 4-5 shown, buffer fixing members 6 are provided at the four corner positions of the back of the cabinet body 1. The two arms of the buffer fixing member 6 are provided with fixing holes 61 for fixing the cabinet body 1 on the wall to reduce the overall shaking degree of the cabinet body 1; a buffer groove 62 is provided in the middle of the buffer fixing member 6. Generally, the material of the buffer fixing member 6 is rubber. When the cabinet body 1 shakes, the buffer fixing member 6 is squeezed and deformed, and the buffer groove 62 can provide a deformation space to improve the buffering ability for the cabinet body 1.

[0046] A shock-absorbing pad 17 is provided at the base of the cabinet body 1 to further reduce the shaking degree of the cabinet body 1 when affected by the shaking of the hull.

[0047] A plurality of heat dissipation grooves 111 are provided on the cabinet walls of the high-temperature compartment 11; a blower housing 8 is provided at the bottom of the high-temperature compartment 11, and a ventilation opening 81 is provided at the top of the blower housing 8;

[0048] A blower is installed inside the blower housing 8. The blower housing 8 plays a protective role for the blower. The airflow generated by the blower is transmitted out from the ventilation opening 81 and out of the high-temperature compartment 11 from the heat dissipation grooves 111, forming an air-cooled airflow cycle to reduce the temperature inside the high-temperature compartment 11.

[0049] A temperature sensor 14 is provided inside the high-temperature compartment 11. The temperature sensor 14 is an existing device that senses the temperature inside the compartment in real time, converts the temperature information into an electrical signal and transmits it to the terminal. The terminal adjusts the operating power of the blower in real time according to the preset temperature standard range based on the temperature change inside the compartment, enhancing the monitoring and control capabilities of the temperature inside the high-temperature compartment 11, enabling the management personnel to timely understand and control the temperature of the high-temperature compartment 11 and avoid safety accidents.

[0050] A fixing mechanism 5 is provided inside the high-temperature compartment 11. As Figure 3As shown in the figure, the fixing mechanism 5 includes a fixing plate 51 and a number of buckles 52. The fixing plate 51 is provided with a weight-reducing groove 511. Inside the weight-reducing groove 511, there are a number of connecting rods 52. The buckles 52 are distributed on the connecting rods 52. Vertically provided on the top of the buckle 52 is a marking plate 54. Since there are many components, the name or number of the fixed components can be pasted on the marking plate 54, which is convenient for quickly finding out various types of components during maintenance.

[0051] The complex marine navigation environment easily causes the cabinet body 1 to shake. Components such as circuit boards in the high-temperature sub-cabinet 11 are fastened to the fixing plate 51 by the buckles 52, which strengthens the fixing strength of the components and avoids situations such as poor contact caused by component wire disconnection.

[0052] The buckle 52 is fixed on the connecting rod 52 by a first fastener 55. Different-sized buckles 52 can be replaced according to the actual size of the components, and the fixing positions of the buckles 52 on the connecting rod 52 can also be flexibly adjusted.

[0053] The inner wall of the high-temperature sub-cabinet 11 is provided with connecting reinforcing ribs 16. Vertically provided on the connecting reinforcing ribs 16 are several rows of mounting holes 161. A second fastener 162 detachably fixes the fixing plate 51 to the inner wall of the high-temperature sub-cabinet 11 through the mounting holes 161. Due to considering the weight problem of the marine cabinet body, the cabinet body has a relatively thin thickness. Compared with directly connecting the fixing plate 51 to the inner wall of the cabinet, the connecting reinforcing ribs 16 have a relatively thick thickness, which can strengthen the connection strength of the fixing plate 51 and avoid the fixing plate 51 falling off during the shaking of the cabinet body. The detachable fixing of the fixing plate 51 can adjust the fixing space of the fixing plate 51 according to the wiring space by selecting mounting holes 161 of different heights, enhancing the flexible applicability of installing components and wiring inside the cabinet.

[0054] The cabinet body 1 is connected with a cabinet door 2. As Figure 6-10 shown, the cabinet door 2 includes a door body 21, a protective frame 22, a cover plate 23, and a split wiring board 24. The protective frame 22 is connected to the back of the door body 21. At the bottom of the protective frame 22 is provided an interface 221. The door body 21 is provided with a through hole 212. A connecting platform 213 is provided in the through hole 212. The connecting platform 213 is located inside the protective frame 22. The cover plate 23 is detachably fixed to the protective frame 22 by a third fastener 231.

[0055] At the edge of the door body 21 is provided a connecting sealing strip 211, which can improve the sealing performance after the door body 21 is closed.

[0056] The split wiring board 24 includes a control panel 241 and a lining board 242. The control panel 241 is provided with a first connection hole 246, the lining board 242 is provided with a second connection hole 247, the connection platform 213 is provided with a third connection hole 214, and a fourth fastener 248 passes through the third connection hole 214, the first connection hole 246, and the second connection hole 247 to detachably fix the split wiring board 24 on the cabinet door 2;

[0057] The fourth fastener 248 is provided with a nylon gasket 249, which plays a protective role at the fastening part of the door body 21, avoiding over-tightening of the fourth fastener 248 and scratching the surface of the door body 21, especially at the opening of the door body 21, so as to avoid affecting the sealing performance of the door body 21.

[0058] The lining board 242 is provided with several row wire grooves 243. The row wire grooves 243 are horizontally provided with several wire winding grooves 2431. When wiring the control buttons and meters on the control panel 241, the cables can be wound around the respective wire winding grooves 2431, which facilitates the wiring and fixing of the cables on the lining board 242 and is beneficial to the neat arrangement of the wires and the fixing of the cables.

[0059] The edge of the lining board 242 is provided with a limit frame 244, and the row wire grooves 243 are located within the limit frame 244. The limit frame 244 restricts each cable and component within the frame, avoiding disordered wiring and entanglement with other cables in the cabinet, and also avoiding damage to the cables by the hinge of the door body 21 when opening and closing the door body 21.

[0060] The cover plate 23 encloses all the cables on the lining board 242 within the protection frame 22. The detachable connection of the cover plate 23 facilitates the disassembly and assembly of the cover plate 23 and is convenient for the maintenance of the wiring. The interface 221 facilitates the connection of the cables within the protection frame 22 to external cables. The interface 221 is preferably a ceramic interface, and the ceramic interface has good high-temperature resistance and insulation properties, which is suitable for the application environment of the wiring of the marine cabinet door.

[0061] The door body 21 and the split wiring board 24 are separately arranged. First, place the split wiring board 24 on the workbench, install all the control buttons and meters on the control panel 241, and complete the wiring and wire arrangement of the cables on the lining board 242, and then install the prefabricated split wiring board 24 on the door body 21.

[0062] The inner wall of the normal-temperature compartment 12 is connected with a filtering component 3, and the outer wall of the normal-temperature compartment 12 is connected with a ventilation louver 4. The filtering component 3 is communicated with the ventilation louver 4;

[0063] Such as Figure 11-14As shown in the figure, the filtering component 3 includes a mesh plate 31, a filter plate 32, and a filter net 36. The filter plate 32 is provided with a filter groove 37, which is located between the filter net 36 and the mesh plate 31. The mesh plate 31 is fixed to the outer wall of the normal temperature cabinet 12, and the filter plate 32 is located between the mesh plate 31 and the outer wall of the normal temperature cabinet 12.

[0064] Weight reduction openings 311 are provided on all four sides of the mesh plate 31, which can reduce the overall weight of the filtering component 3 without affecting the electromagnetic shielding performance.

[0065] The mesh plate 31 is detachably fixed to the outer wall of the normal temperature cabinet 12 through fifth fasteners 33, which facilitates the disassembly and assembly of the mesh plate 31 and the filter plate 32 for cleaning or replacing the filter net 36.

[0066] Raised positioning blocks 34 are provided on all four sides of the filter plate 32, and limit openings 35 are provided on all four sides of the mesh plate 31. The positions and sizes of the limit openings 35 are adapted to those of the positioning blocks 34. When assembling the filter plate 32 and the mesh plate 31, each positioning block 34 is stuck in the corresponding limit opening 35 to play a positioning role, which not only facilitates the installation of the mesh plate 31 but also avoids the loosening of the mesh plate 31 during subsequent use.

[0067] The filter groove 37 is provided with filter reinforcing ribs 38 to enhance the overall strength of the filter plate 32 and reduce the deformation of the filter groove 37 after the filter plate 32 is squeezed.

[0068] In the normal temperature cabinet 12, air cooling is required to control the temperature inside the cabinet to ensure the safe operation of each component inside the cabinet. Several filtering components 3 can be installed on the inner wall of the cabinet, serving as the air outlet and the air inlet respectively. A blower can be installed on the filtering component 3 serving as the air inlet to conduct air flow exchange inside and outside the cabinet. Among them, the air flow in and out needs to pass through the filter plate 32, and the filter net 36 filters the dust in the passing gas to prevent the components inside the cabinet from being polluted; while the mesh plate 31 is made of metal material, which can form electromagnetic shielding at the air outlet. A ventilation louver 4 is provided on the outer wall of the cabinet to achieve the effects of ventilation and heat dissipation, and the structure of the louver is conducive to daily cleaning.

[0069] Copper foils 7 are provided at the opening of the cabinet body 1, the edge of the door body 21, the connection surface of the protective frame 22, the interface 221, the edge of the inner lining plate 242, and the periphery of the mesh plate 31. The copper foils 7 can form an electromagnetic shielding effect at each sealing position to prevent the external environment from causing electromagnetic interference to the components inside the cabinet.

[0070] The preferred embodiments of the present utility model have been specifically described above. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
