Description

Technical Field

[0001] This utility model relates to the field of ship power distribution boxes, and more specifically, it relates to a ship power distribution box with an isolation structure. Background Technology

[0002] Shipboard power distribution boxes are key equipment in a ship's electrical system responsible for regional power distribution and control. They are typically installed in a distributed manner according to the ship's power consumption areas (such as engine room, cargo hold, living quarters, deck, etc.). Their core function is to receive electrical energy from the main distribution board or emergency distribution board and then safely distribute the power to the electrical equipment in each area through internal protection and control components such as circuit breakers, fuses, and contactors.

[0003] To achieve orderly management and independent control of different electrical components and facilitate daily operation and maintenance, existing shipboard electrical distribution boxes typically have isolation structures inside the box to separate multiple independent power distribution areas. However, this separation method often hinders air circulation and heat exchange within the box, making each power distribution area a relatively closed space. The heat generated by the electrical components in each area cannot be quickly dissipated to the outside of the box through natural convection, which easily causes heat to accumulate in local areas, leading to a continuous increase in temperature. This not only affects the working stability and lifespan of the electrical components, but may also cause safety hazards such as aging of wiring and short circuits due to high temperatures. Especially during ship navigation, the large temperature difference and high humidity between the inside and outside of the box further exacerbate the negative effects of poor heat dissipation.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a ship power distribution box with an isolation structure. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ship power distribution box with an isolation structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ship power distribution box with an isolation structure, including a power distribution box body, on which a ventilation slot is provided. The power distribution box body is provided with multiple vertically adjustable isolation plates, which isolate multiple independent power distribution areas inside the power distribution box body. Multiple exhaust pipes with open tops and closed bottoms are embedded and fixed at the top of the power distribution box body, and the bottom of the exhaust pipes extends to the bottom of the power distribution box body. The outer wall of the exhaust pipes is provided with multiple exhaust holes arranged in a circular and vertical array on the internal area of ​​the power distribution box body. The isolation plates are provided with circular through slots for the exhaust pipes to pass through. A fan is installed at the top of the exhaust pipes.

[0007] Preferably, both sides of the distribution box are interconnected with connecting shells, and the interior of the connecting shells is fixedly connected with guide rails. The two sides of the isolation plate are slidably connected to the guide rails by sliders.

[0008] Preferably, the surface of the connecting shell has multiple through holes A arranged in a vertical array, and the surface of the slider has screw holes. The slider is installed by passing a screw through the through hole A and rotating it clockwise to fix the height of the slider relative to the connecting shell.

[0009] Preferably, the top of the distribution box is provided with a support structure to support the fan.

[0010] Preferably, the support structure includes vertical plates fixed to both sides of the top of the distribution box, and a support platform is welded to the top of the vertical plates, and the fan is embedded and detachably connected to the support platform.

[0011] Preferably, the support platform has a through groove that fits against the outer wall of the fan, and the bottom of the fan is connected to the top of the exhaust pipe by insertion, with the connection sealed by a sealing structure.

[0012] Preferably, the support platform is fixedly connected to screws on both sides of the through groove, and the fan is fixedly connected to connecting plates with through holes B on both sides. Nuts are threaded onto the outer side wall of the screws.

[0013] Preferably, the diameter of the exhaust holes on the exhaust pipe increases sequentially from top to bottom.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The design of the exhaust pipe extending to the bottom of the box in this utility model can simultaneously extract and exhaust the hot air deposited at the bottom of the box. Combined with the exhaust holes covering multiple areas, it ensures that the heat of each independent power distribution area can be efficiently discharged, solving the problem of local heat accumulation caused by the isolation structure of the traditional ship power distribution box in the background technology, and ensuring the stable operation of electrical components in the power distribution box under the turbulence of the ship. 2. In this utility model, the diameter of the exhaust holes on the exhaust pipe increases from top to bottom. Combined with the characteristic of hot air flowing upward, the upper area is closer to the fan, and the negative pressure suction is stronger. The smaller diameter exhaust holes can avoid local airflow turbulence caused by excessive suction, while accurately capturing the rising hot air. The lower area is farther from the fan, and the negative pressure is relatively weaker. The larger diameter exhaust holes can compensate for the insufficient exhaust caused by the decrease in suction by increasing the flow cross-sectional area, ensuring that the hot air deposited at the bottom of the box or the lower isolation area can enter the exhaust pipe efficiently. 3. This utility model provides a stable installation reference for the fan through the support structure. Especially in the complex environment of ship navigation with turbulence and vibration, it can effectively prevent the fan from shifting due to shaking or displacement, ensuring the sealing of the negative pressure exhaust channel and avoiding the decrease in heat dissipation efficiency caused by air leakage.

[0017] like Figure 1-6 As shown, this utility model provides a ship power distribution box with an isolation structure, including a power distribution box body 1, on which a ventilation slot 17 is provided. Multiple adjustable isolation plates 2 are provided inside the power distribution box body 1 to isolate multiple independent power distribution areas inside the power distribution box body 1. Multiple exhaust pipes 3 with open tops and closed bottoms are embedded and fixed at the top of the power distribution box body 1, and the bottom of the exhaust pipes 3 extends to the bottom of the power distribution box body 1. Multiple exhaust holes 4 arranged in a circular and vertical array are provided on the outer wall of the exhaust pipes 3 in the area inside the power distribution box body 1. Circular through slots 5 are provided on the isolation plates 2 for the exhaust pipes 3 to pass through. A fan 6 is installed at the top of the exhaust pipes 3.

[0018] Multiple adjustable partitions 2 inside the distribution box 1 flexibly separate independent power distribution areas according to the size and layout requirements of electrical components, achieving physical isolation of different circuit modules and preventing signal interference or fault propagation. Simultaneously, the circular slots 5 on the partitions 2 provide space for the exhaust pipes 3, ensuring the isolation structure does not obstruct heat dissipation. When the distribution box is working, the fan 6 of the top exhaust pipe 3 starts, creating negative pressure within the exhaust pipe 3. This causes hot air (including heat generated by components in each independent power distribution area) inside the distribution box 1 to enter the pipe through the circumferentially and vertically arranged exhaust holes 4 (covering the height of each isolation area) on the outer wall of the exhaust pipe 3. The hot air rises along the exhaust pipe 3 and is discharged outside the box from the top opening. At the same time, external cold air continuously replenishes the box through the ventilation slots 17 on the side of the box, forming a convection cycle of "cold air in - directional hot air out". The design of the exhaust pipe 3 extending to the bottom of the box can simultaneously extract and exhaust the hot air deposited at the bottom of the box. Combined with the exhaust holes 4 covering multiple areas, it ensures that the heat of each independent power distribution area can be efficiently discharged, solving the problem of local heat accumulation caused by the isolation structure of traditional ship power distribution boxes, and ensuring the stable operation of electrical components in the power distribution box under the turbulence of the ship.

[0019] Among them, the diameter of the exhaust hole 4 on the exhaust pipe 3 increases from top to bottom. Combined with the characteristic of hot air flowing upward, the upper area is close to the fan 6, and the negative pressure suction is stronger. The smaller diameter exhaust hole 4 can avoid local airflow turbulence caused by excessive suction, while accurately capturing the rising hot air. The lower area is farther away from the fan 6, and the negative pressure is relatively weak. The larger diameter exhaust hole 4 can compensate for the insufficient exhaust caused by the decrease in suction by increasing the flow cross-sectional area, ensuring that the hot air deposited at the bottom of the box or the lower isolation area can enter the exhaust pipe 3 efficiently.

[0020] The following is the specific structure for adjusting the height of the isolation plate 2: Both sides of the distribution box 1 are interconnected with connecting shells 7, and the inside of the connecting shells 7 is fixedly connected with guide rails 8. The two sides of the isolation plate 2 are slidably connected to the guide rails 8 by sliders 9. The surface of the connecting shells 7 has multiple through holes A10 arranged in a vertical array. The surface of the sliders 9 has screw holes 11. The sliders 9 are installed by passing screws through the through holes A10 and rotating them clockwise into the screw holes 11, thus fixing the height of the sliders 9 relative to the connecting shells 7.

[0021] During adjustment, first remove the screw that passes through the through hole A10 on the surface of the connecting shell 7 and is screwed into the screw hole 11 of the slider 9 by turning it counterclockwise, thus releasing the slider 9 from the connecting shell 7. Then, according to the required height of the isolation area, push the isolation plate 2 so that the sliders 9 on both sides slide up and down along the guide rail 8 inside the connecting shell 7 until the isolation plate 2 reaches the target position. Next, observe and adjust the slider 9 so that the screw hole 11 on the surface of the slider 9 is aligned with the through hole A10 at the corresponding height on the connecting shell 7. Finally, pass the screw through the aligned through hole A10, turn it clockwise and tighten it into the screw hole 11 to fix the slider 9 to the connecting shell 7, thereby completing the height adjustment of the isolation plate 2.

[0022] Furthermore, the top of the distribution box 1 is provided with a support structure 12 to support the fan 6. The support structure 12 can provide a stable installation reference for the fan 6. Especially in the complex environment of ship navigation with turbulence and vibration, it can effectively prevent the fan 6 from shifting or displacing with the top of the exhaust pipe 3 due to shaking or displacement, ensuring the sealing of the negative pressure exhaust channel and avoiding the decrease in heat dissipation efficiency caused by air leakage.

[0023] This utility model also provides a specific structure of the support structure 12: the support structure 12 includes vertical plates 1201 fixed to both sides of the top of the distribution box 1, and a support platform 1202 is welded to the top of the vertical plates 1201. The fan 6 is embedded and detachably connected to the support platform 1202. The support platform 1202 has a through groove 1203 that fits against the outer wall of the fan 6. The bottom of the fan 6 is connected to the top of the exhaust pipe 3 by insertion. The connection is sealed by a sealing structure. Thus, the through groove 1203 on the support platform 1202 fits against the outer wall of the fan 6. It achieves precise positioning of the fan 6 and restricts the lateral displacement of the fan 6 through the mating surface to prevent docking misalignment caused by vibration; the embedded detachable connection design facilitates quick assembly and disassembly of the fan 6 (such as not needing to completely remove the support structure 12 during maintenance), reducing maintenance costs; and the insertion connection between the bottom of the fan 6 and the exhaust pipe 3, combined with the sealing structure (such as a rubber sealing ring), can effectively block external moisture and salt spray from entering the interior of the distribution box 1, while preventing internal hot air leakage, ensuring the stability of the negative pressure in the exhaust pipe 3, and ensuring that the extraction efficiency of each exhaust port 4 is not affected.

[0024] The following is the specific detachable structure between the fan 6 and the support platform 1202: the support platform 1202 is fixedly connected to both sides of the through groove 1203 with screws 13, the fan 6 is fixedly connected to both sides with connecting plates 14 having through holes B15, and nuts 16 are threaded onto the outer side wall of the screws 13.

[0025] When installing the fan 6, first insert it into the through groove 1203 of the support platform 1202, so that the bottom of the fan 6 is aligned with the top of the exhaust pipe 3. At the same time, the through holes B15 on the connecting plates 14 on both sides of the fan 6 are also fitted into the screws 13 on both sides of the support platform 1202 (the through holes B15 and screws 13 are aligned before the fan 6 is inserted into the through groove 1203). Finally, screw nuts 16 into the outer wall of the screws 13 and tighten them. The connecting plates 14 are fixed by pressing the nuts 16 together. When disassembling, first unscrew the nuts 16 on the screws 13 counterclockwise to release the constraint on the connecting plates 14. Then lift the fan 6 upwards so that the through holes B15 are disengaged from the screws 13 and the bottom of the fan 6 is separated from the exhaust pipe 3. The fan 6 can then be taken out from the through groove 1203.
