Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to a high-voltage switchboard arc-extinguishing structure and a ship. Background Technology

[0002] PCTC (Pure Car and Truck Carrier) vessels are used to transport cars and are typically equipped with high-voltage switchboards. These switchboards may generate high-temperature, high-pressure exhaust gases due to arcing or explosion. (See reference...) Figures 1-2 To exhaust exhaust gases, related technologies typically install an exhaust gas box 2' above the high-voltage switchboard enclosure 1', with the opening of the exhaust gas box 2' facing upwards and connected to an exhaust gas pipe. This allows the exhaust gases inside the high-voltage switchboard enclosure 1' to be discharged sequentially through the exhaust gas box 2' and the exhaust gas pipe. However, a problem exists: because the opening of the exhaust gas box 2' faces upwards, space needs to be reserved above the exhaust gas box 2' for the installation of the exhaust gas pipe. Generally, the upper surface of the exhaust gas box 2' needs to be at least 400mm away from the upper deck, requiring the upper deck to be set higher, resulting in reduced overhead space. For PCTC (Potentially Critical Toll Collection) systems, this leads to a reduction in vehicle transport spaces, affecting the ship's loading efficiency and economic benefits. Utility Model Content

[0007] An exhaust gas duct is installed on the side wall of the exhaust gas box, and the inner cavity of the exhaust gas duct is connected to the exhaust port.

[0008] As a preferred embodiment of the arc-extinguishing structure of the high-voltage switchboard, the exhaust gas pipe is a straight pipe, and the extension direction of the exhaust gas pipe is parallel to the deck.

[0009] As a preferred embodiment of the arc-extinguishing structure of the high-voltage switchboard, the opening at the end of the exhaust gas pipe away from the exhaust gas box faces the deck for mounting the high-voltage switchboard box.

The extension direction of the first connecting section is parallel to the deck, the transition section is arc-shaped, and the second connecting section extends along the height direction of the ship.

[0011] As a preferred embodiment of the arc-extinguishing structure of the high-voltage switchboard, the inner cavity of the exhaust gas pipe is provided with a metal mesh.

[0012] As a preferred embodiment of the arc-extinguishing structure of the high-voltage switchboard, a flange is provided at the end of the exhaust gas pipe away from the exhaust gas box, and the flange is used to connect to an external pipe.

[0016] As a preferred embodiment of the vessel, the distance between the upper surface of the exhaust gas box and the deck located above the exhaust gas box is less than 400 mm.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides an arc-venting structure for a high-voltage switchboard, used to release exhaust gas inside a high-voltage switchboard enclosure for installation on a ship's deck. The arc-venting structure includes an exhaust gas chamber and an exhaust gas pipe. The exhaust gas chamber is positioned above the high-voltage switchboard enclosure and has an arc-venting channel and an exhaust port connected to the channel. Exhaust gas generated inside the high-voltage switchboard enclosure flows into the arc-venting channel, and the exhaust port is located on the side wall of the exhaust gas chamber. The exhaust gas pipe is located on the side wall of the exhaust gas chamber, and its inner cavity connects to the exhaust port. High-temperature, high-pressure exhaust gas generated inside the high-voltage switchboard enclosure sequentially passes through the arc-venting channel and the exhaust port into the inner cavity of the exhaust gas pipe and is then discharged through the exhaust gas pipe. Furthermore, the location of the exhaust port and the exhaust gas pipe on the side wall of the exhaust gas chamber ensures that the exhaust gas pipe does not occupy the space above the exhaust gas chamber, allowing the deck above the exhaust gas chamber to be positioned closer to it, thus increasing the overhead space.

[0019] This utility model also provides a ship, including a deck, a high-voltage switchboard enclosure, and the aforementioned high-voltage switchboard arc-extinguishing structure. The high-voltage switchboard enclosure is located on the deck, and the exhaust gas box is located above the high-voltage switchboard enclosure. The exhaust gas generated inside the high-voltage switchboard enclosure can flow into the arc-extinguishing channel. The exhaust gas can sequentially enter the inner cavity of the exhaust gas pipe through the arc-extinguishing channel and the exhaust port, and then be discharged through the exhaust gas pipe. In addition, the exhaust port is opened on the side wall of the exhaust gas box, and the exhaust gas pipe is located on the side wall of the exhaust gas box, so that the exhaust gas pipe does not occupy the space above the exhaust gas box. Therefore, the deck above the exhaust gas box can be set closer to the exhaust gas box, thereby increasing the space above. For PCTC, this setting will not affect the number of vehicle transport spaces, thereby avoiding affecting the ship's loading efficiency and economic benefits. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0033] Example 1

[0034] PCTCs (Portable Car Transporters) are used to transport vehicles and typically feature high-voltage switchboards. These switchboards may generate high-temperature, high-pressure exhaust gases due to arcing or explosion. To expel these gases, a waste gas box is usually installed above the switchboard enclosure, with its opening facing upwards and connected to a waste gas pipe. This allows the exhaust gases inside the switchboard enclosure to be discharged sequentially through the waste gas box and the pipe. However, this design presents a problem: because the waste gas box opening faces upwards, space must be reserved above it for the waste gas pipe installation. Generally, the upper surface of the waste gas box needs to be at least 400mm above the upper deck, requiring the upper deck to be set relatively high, thus reducing overhead space. For PCTCs, this results in fewer vehicle transport bays, impacting ship loading efficiency and economic benefits.

[0035] In response, this embodiment provides a high-voltage switchboard arc-venting structure to solve the problem in the prior art that the upper surface of the exhaust gas box needs to be at least 400mm away from the upper deck, which requires the upper deck to be set higher and reduces the space above. It can be used in the field of marine technology, specifically in PCTC, and in other embodiments, it can also be applied to other types of ships.

[0036] In high-voltage switchboard 1, high-temperature and high-pressure exhaust gases may be generated due to arcing and explosion. (Refer to...) Figures 3-5 The arc-venting structure of the high-voltage switchboard is used to release the exhaust gas inside the high-voltage switchboard box 1, which is used to be installed on the deck of a ship. The arc-extinguishing structure of the high-voltage switchboard includes an exhaust gas box 2 and an exhaust gas pipe 3. The exhaust gas box 2 is installed above the high-voltage switchboard box 1 and has an arc-extinguishing channel and an exhaust port connected to the arc-extinguishing channel. The exhaust gas generated inside the high-voltage switchboard box 1 can flow into the arc-extinguishing channel, and the exhaust port is located on the side wall of the exhaust gas box 2. The exhaust gas pipe 3 is located on the side wall of the exhaust gas box 2, and the inner cavity of the exhaust gas pipe 3 is connected to the exhaust port. The high-temperature and high-pressure exhaust gas generated inside the high-voltage switchboard box 1 can enter the inner cavity of the exhaust gas pipe 3 through the arc-extinguishing channel and the exhaust port in sequence, and be discharged by the exhaust gas pipe 3. In addition, the exhaust port is located on the side wall of the exhaust gas box 2, and the exhaust gas pipe 3 is located on the side wall of the exhaust gas box 2, so that the exhaust gas pipe 3 does not occupy the space above the exhaust gas box 2. Therefore, the deck above the exhaust gas box 2 can be set closer to the exhaust gas box 2, thereby increasing the space above.

[0037] Continue to refer to Figures 3-5 The exhaust gas pipe 3 is a straight pipe, and the extension direction of the exhaust gas pipe 3 is parallel to the deck. Thus, the exhaust gas is directed to one side of the exhaust gas box 2 through the exhaust gas pipe 3. This setting makes the overall structure of the exhaust gas pipe 3 simple and easy to process and assemble.

[0038] Continue to refer to Figures 3-5The inner cavity of the exhaust duct 3 is equipped with a metal mesh 32, which can block debris from passing through the inner cavity of the exhaust duct 3 and prevent rats from entering the exhaust gas box 2. Optionally, the metal mesh 32 is located at the end of the exhaust duct 3 away from the exhaust gas box 2, so as to facilitate cleaning and disassembly.

[0039] Continue to refer to Figures 3-5 A flange 31 is provided at the end of the exhaust gas pipe 3 away from the exhaust gas box 2. The flange 31 is used to connect to an external pipe, which facilitates the connection between the exhaust gas pipe 3 and the external pipe. The external pipe can be the ship's exhaust pipe, through which the exhaust gas from the exhaust gas pipe 3 can be discharged from the ship.

[0040] Continue to refer to Figures 3-5 A sealing structure is provided between the exhaust gas pipe 3 and the side wall of the exhaust gas box 2 to prevent exhaust gas from leaking from the connection between the exhaust gas pipe 3 and the side wall of the exhaust gas box 2.

[0041] Continue to refer to Figures 3-5 The cross-section of the exhaust gas pipe 3 is rectangular, and the width of the cross-section of the exhaust gas pipe 3 is not less than 300mm, thereby ensuring that the cross-sectional area of ​​the exhaust gas pipe 3 is large enough to meet the exhaust gas discharge requirements. Furthermore, the width of the cross-section of the exhaust gas pipe 3 is set between 300mm and 400mm, specifically 300mm, 310mm, 320mm, 330mm, 340mm, 350mm, 360mm, 370mm, 380mm, 390mm, or 400mm; in this embodiment, it is specifically 350mm.

[0042] Example 2

[0043] This embodiment provides another high-voltage switchboard arc extinguishing structure. Compared with the high-voltage switchboard arc extinguishing structure in Embodiment 1 above, the specific structure of the exhaust pipe 3 of the high-voltage switchboard arc extinguishing structure in this embodiment is different.

[0044] In the first embodiment described above, the space above the exhaust gas tank 2 is no longer excessively occupied. However, since the exhaust gas pipe 3 is a straight pipe and its extension direction is parallel to the deck, it will occupy a significant amount of space on one side of the exhaust gas tank 2. Therefore, refer to... Figure 6 In this embodiment, the opening of the end of the exhaust gas pipe 3 away from the exhaust gas box 2 faces the deck for installing the high-voltage distribution board box 1, so that the exhaust gas pipe 3 is bent as a whole. One end of the exhaust gas pipe 3 is connected to the exhaust gas box 2, while the opening of the other end faces the lower deck. External pipes can be connected to the lower part of the exhaust gas pipe 3, thereby saving space on one side of the exhaust gas box 2.

[0045] Continue to refer to Figure 6The exhaust gas duct 3 has a first connecting section 301, a transition section 302 and a second connecting section 303 connected in sequence. The extension direction of the first connecting section 301 is parallel to the deck, the transition section 302 is arc-shaped, and the second connecting section 303 extends along the height direction of the ship. By setting the first connecting section 301 and the second connecting section 303 and connecting them through the arc-shaped transition section 302, the flow resistance of exhaust gas in the exhaust gas duct 3 can be reduced as much as possible.

[0046] Example 3

[0047] This embodiment provides a vessel, including the high-voltage switchboard arc-extinguishing structure in any of the above embodiments. In this embodiment, the vessel is a PCTC, while in other embodiments, it may be other types of vessels.

[0048] The vessel also includes a deck and a high-voltage switchboard enclosure 1. The high-voltage switchboard enclosure 1 is located on the deck, and the exhaust gas box 2 is located above the high-voltage switchboard enclosure 1. Exhaust gas generated inside the high-voltage switchboard enclosure 1 can flow into the arc venting channel. The exhaust gas can then sequentially pass through the arc venting channel and the exhaust port into the inner cavity of the exhaust gas pipe 3, and be discharged through the exhaust gas pipe 3. Furthermore, the exhaust port is located on the side wall of the exhaust gas box 2, and the exhaust gas pipe 3 is also located on the side wall of the exhaust gas box 2, so that the exhaust gas pipe 3 does not occupy the space above the exhaust gas box 2. Therefore, the deck above the exhaust gas box 2 can be set closer to the exhaust gas box 2, thereby increasing the overhead space. For PCTC, this arrangement will not affect the number of vehicle transport spaces, thus avoiding any impact on the vessel's loading efficiency and economic benefits. For other types of vessels, this arrangement can also increase overhead space, providing more space for cargo loading or personnel activities.

[0049] Optionally, the distance between the upper surface of the exhaust gas box 2 and the deck above it is less than 400mm, thereby significantly reducing the distance between the upper surface of the exhaust gas box 2 and the deck above it compared to the scheme where the exhaust port is located on the upper surface of the exhaust gas box 2. In this embodiment, the distance between the upper surface of the exhaust gas box 2 and the deck above it is also set according to actual needs, specifically 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, or 350mm. In this embodiment, to further increase the upper space, the distance between the upper surface of the exhaust gas box 2 and the deck above it can be set to less than 200mm.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
