Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a reversible air pipe. Background Art

[0002] Air pipes are used to balance the air pressure in the hold and prevent the intrusion of seawater, dust, and other impurities. However, common deck iron fittings, such as air pipes and air pipe heads, are typically designed to be fixed. Because the water inlet point of the air pipe on the main deck is at least 760 mm, combined with the height of the air pipe head itself, the air pipe and pipe head are approximately one meter above the main deck, which can affect cargo loading and unloading.

[0003] The existing layout of air pipes and air pipe heads in the deck loading area has the following problems:

[0004] First, to avoid the cargo area, each air pipe was led to the non-cargo area through a longer pipeline under the main deck, resulting in an increase in the material of the air pipe and increasing the construction workload and difficulty of the air pipe layout.

[0005] Second, for air pipes and pipe heads that are difficult to access non-cargo areas, placing them at the edge of the deck will affect cargo loading and unloading due to their high height. Furthermore, there is a risk that the air pipes and pipe heads will be damaged by cargo impact, causing damage to the corresponding main deck and endangering the safety of the ship.

[0006] 3. Since the air pipe head is designed to be fixed, even if the air pipe head is temporarily disassembled during loading and unloading, it is difficult to load and unload the air pipe head due to the lack of additional support, and the amount of disassembly work is increased. At the same time, the scattered air pipe heads have no fixed and storage space, which may lead to their damage and loss. Utility Model Content

[0007] The purpose of the utility model is to provide a reversible air pipe, which can be connected to the air pipe and the air pipe head and then turned over and laid down, thereby effectively lowering the height of the air pipe and facilitating the loading and unloading of cargo on the deck. The original appearance of the air pipe can be quickly restored by rotating the connecting rod.

[0008] In order to achieve the above-mentioned purpose, the utility model provides a reversible air pipe, including a fixed air pipe, a connecting air pipe, an air pipe head, a rotating connecting rod and a fixed shaft. The fixed air pipe is fixed on the deck, and the bottom of the connecting air pipe is detachably connected to the top of the fixed air pipe. The fixed shaft is connected to the side wall of the fixed air pipe. A connecting eye plate is provided on the side wall of the connecting air pipe. The first end of the rotating connecting rod is rotatably connected to the connecting eye plate, and the second end of the rotating connecting rod is rotatably connected to the fixed shaft. The axis of the fixed shaft is perpendicular to the axis of the connecting hole of the connecting eye plate, and the air pipe head is arranged on the top of the connecting air pipe.

[0009] As a preferred solution of the present invention, the fixed air pipe and the connecting air pipe are connected via a flange.

[0010] As a preferred solution of the present invention, a blind flange connected to the fixed air pipe is also included.

[0011] As a preferred solution of the present invention, a sealing gasket is sandwiched between the fixed air pipe and the connecting air pipe.

[0012] As a preferred solution of the present invention, the connecting air pipe and the air pipe head are connected via a flange.

[0013] As a preferred solution of the present invention, a sealing gasket is sandwiched between the connecting air pipe and the air pipe head.

[0014] As a preferred solution of the present invention, the height of the fixed air pipe extending above the deck is less than the length of the connecting air pipe.

[0015] As a preferred solution of the present invention, the fixed air pipe, the connecting air pipe, the rotating connecting rod and the fixed shaft are all provided with an anti-corrosion coating.

[0016] Compared with the prior art, the reversible air tube of the present invention has the following advantages:

[0017] The utility model first disassembles and separates the connecting air pipe from the fixed air pipe, then rotates the connecting eye plate of the connecting air pipe around the first end of the rotating connecting rod, and then rotates the second end of the rotating connecting rod around the fixed axis, so that the connecting air pipe and the air pipe head are flipped over and laid down, effectively lowering the height of the air pipe and facilitating the loading and unloading of cargo on the deck. After the cargo loading and unloading is completed, the air pipe can be quickly restored to its original appearance to ensure the navigation safety of the ship, increase the possibility of arranging the air pipe near the edge of the deck, and reduce the difficulty of air pipe arrangement design. The air pipe and the air pipe head are connected to the fixed air pipe through the rotating connecting rod, avoiding the risk of damage and loss of the air pipe head due to the lack of fixing and storage space.

[0024] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "top", "bottom", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 4 As shown, a reversible air pipe according to a preferred embodiment of the present invention includes a fixed air pipe 1, a connecting air pipe 2, an air pipe head 3, a rotating connecting rod 4 and a fixed shaft 5. The fixed air pipe 1 is fixed on the deck 7, and the bottom of the connecting air pipe 2 is detachably connected to the top of the fixed air pipe 1. The fixed shaft 5 is connected to the side wall of the fixed air pipe 1. A connecting eye plate 21 is provided on the side wall of the connecting air pipe 2. The first end of the rotating connecting rod 4 is rotatably connected to the connecting eye plate 21, and the second end of the rotating connecting rod 4 is rotatably connected to the fixed shaft 5. The axis of the fixed shaft 5 is perpendicular to the axis of the connecting hole of the connecting eye plate 21, and the air pipe head 3 is arranged on the top of the connecting air pipe 2.

[0027] The utility model first disassembles and separates the connecting air pipe 2 from the fixed air pipe 1, then rotates the connecting eye plate 21 of the connecting air pipe 2 around the first end of the rotating connecting rod 4, and then rotates the second end of the rotating connecting rod 4 around the fixed axis 5, so as to realize the connection of the air pipe 2 and the air pipe head 3 being flipped over and laid down, effectively lowering the height of the air pipe and facilitating the loading and unloading of cargo on the deck 7. After the cargo loading and unloading is completed, the original appearance of the air pipe can be quickly restored to ensure the navigation safety of the ship, and the possibility of arranging the air pipe near the edge of the deck 7 can be increased, reducing the difficulty of the air pipe arrangement design. The air pipe and the air pipe head 3 are connected to the fixed air pipe 1 through the rotating connecting rod 4, avoiding the risk of damage and loss of the air pipe head 3 due to the lack of fixing and storage space.

[0028] Exemplarily, the fixed air pipe 1 and the connecting air pipe 2 are connected by a flange, which facilitates quick installation and removal of the fixed air pipe 1 and the connecting air pipe 2 and ensures good connection stability. Furthermore, a sealing gasket is sandwiched between the fixed air pipe 1 and the connecting air pipe 2 to ensure a good sealing effect between the fixed air pipe 1 and the connecting air pipe 2.

[0029] Exemplarily, the retractable air pipe also includes a blind flange 6 connected to the fixed air pipe 1, so that after the connecting air pipe 2 is folded down, the fixed air pipe 1 is temporarily closed by the blind flange 6 to prevent foreign matter from entering the cabin through the fixed air pipe 1.

[0030] For example, the connecting air pipe 2 and the air pipe head 3 are connected by a flange, which facilitates the subsequent maintenance or replacement of the air pipe head 3. Furthermore, a sealing gasket is sandwiched between the connecting air pipe 2 and the air pipe head 3 to ensure good air tightness between the connecting air pipe 2 and the air pipe head 3.

[0031] Specifically, the height of the fixed air pipe 1 extending above the deck 7 is less than the length of the connecting air pipe 2, ensuring that after the connecting air pipe 2 and the air pipe head 3 are laid down, the height of the retractable air pipe is lowered, making cargo loading and unloading more convenient.

[0032] Exemplarily, the fixed air pipe 1, the connecting air pipe 2, the rotating connecting rod 4 and the fixed shaft 5 are all provided with an anti-corrosion coating to ensure that the overall anti-corrosion effect of the reversible air pipe is good.

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense.
