[0002] For safety reasons, roll-on / roll-off (Ro-Ro) ships are equipped with airtight doors in their passageways during navigation. Generally, the airtight door is sealed by fixing rubber sealing rings around the door panel and pressing them tightly against the door frame. Both the door panel and the door frame are vertically aligned. This sealing structure has no other problems, but it can be further improved to enhance the sealing effect. Utility Model Content

[0003] In view of the above-mentioned shortcomings, this utility model provides an airtight door sealing structure for roll-on / roll-off ship channel equipment, which has strong airtightness, good sealing effect, safety, stability and reliability, and simple overall structure.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] An airtight door sealing structure for a roll-on / roll-off (Ro-Ro) ship passageway includes a door panel, a passageway door frame, and a passageway threshold. The door panel is hinged to the Ro-Ro ship passageway, and both sides of the door panel are respectively attached to the passageway door frame and the passageway threshold. Sealing gaskets are provided between the door panel and the passageway door frame and the passageway threshold. The door panel is inclined, the passageway door frame is angled to the vertical direction, and the passageway threshold is angled to the horizontal direction. The door panel is provided with a first sealing strip and a second sealing strip. Both the first sealing strip and the second sealing strip have cavities. The first sealing strip has a first V-shaped protrusion, and the second sealing strip has a second V-shaped protrusion. The first V-shaped protrusion is in contact with the passageway door frame, and the second V-shaped protrusion is in contact with the passageway threshold.

[0006] According to one aspect of the present invention, the door panel is provided with a first sealing groove and a second sealing groove, the first sealing strip is fixed in the first sealing groove, and the second sealing strip is fixed in the second sealing groove.

[0007] According to one aspect of the present invention, the door panel is further provided with an auxiliary sealing strip, the auxiliary sealing strip having a cavity inside, and the auxiliary sealing strip having an auxiliary V-shaped protrusion, the auxiliary V-shaped protrusion being in pressure contact with the passage door frame.

[0008] According to one aspect of the present invention, a gasket is provided between the door panel and the passage door frame and the passage threshold respectively, the sealing gasket is fixed around the door panel, and the gasket is fixed on the passage door frame and the passage threshold respectively, and the sealing gasket and the gasket are pressed into contact.

[0009] According to one aspect of the present invention, the door panel is further provided with an auxiliary sealing groove, and the auxiliary sealing strip is fixed in the auxiliary sealing groove.

[0010] According to one aspect of the present invention, the first V-shaped protrusion, the second V-shaped protrusion, and the auxiliary V-shaped protrusion are respectively pressed into contact with the gasket.

[0011] According to one aspect of this utility model, the sealing gasket, the first sealing strip, the second sealing strip, and the auxiliary sealing strip are all made of rubber, and the gasket is made of stainless steel.

[0012] According to one aspect of the present invention, the channel threshold is an inclined flat plate, and the first sealing groove, the second sealing groove, and the auxiliary sealing groove are all strip-shaped grooves.

[0013] According to one aspect of this utility model, there are several auxiliary sealing strips and auxiliary sealing grooves, both of which are regularly distributed on the door panel.

[0014] According to one aspect of the present invention, the door panel is further provided with a telescopic rod, a pin, and a slot. The telescopic rod is connected to the pin, and a slot is provided inside the passage door frame. The pin is driven by the telescopic rod to be inserted into the slot and the slot in sequence to lock the door panel and the passage door frame.

[0015] The advantages of this invention are as follows: When the door panel is closed, due to the inclined design of the door panel (passage door frame, passage threshold), its own weight can compress the sealing gasket, the first sealing strip, and the second sealing strip. Simultaneously, because both the first and second sealing strips have cavities, the first V-shaped protrusion deforms after contacting the passage door frame, and the second V-shaped protrusion deforms after contacting the passage threshold. This results in a better seal at the top, sides, and bottom of the door panel, leading to excellent sealing performance. Thus, this airtight door sealing structure has strong airtightness, is safe, stable, and reliable, and has a simple overall structure. By setting auxiliary sealing strips and auxiliary V-shaped protrusions to contact the passage door frame, this structure can further enhance the sealing performance and achieve an even better sealing effect.

[0023] Example 1

[0024] As shown in Figures 1-3, an airtight door sealing structure for a roll-on / roll-off (Ro-Ro) ship passageway includes a door panel 1, a sealing gasket 2, a first sealing strip 3, a second sealing strip 4, a passageway door frame 6, and a passageway threshold 7. The door panel 1 has a conventional structure. The top of the door panel 1 is hinged to the Ro-Ro ship passageway 15, and the two sides of the door panel 1 are respectively attached to the passageway door frame 6 and the passageway threshold 7. The door panel 1 is inclined at a 15-degree angle to the vertical direction, the passageway door frame 6 is also inclined at a 15-degree angle to the vertical direction, and the passageway threshold 7 is inclined at an angle to the horizontal direction. The structural shapes and arrangements of the door panel 1, the passageway door frame 6, and the passageway threshold 7 are all compatible with each other. The top side of the door panel 1 is provided with a first sealing groove 9, and the bottom of the door panel 1 is provided with a second sealing groove 10. The first sealing groove 9 and the second sealing groove 10 have the same structural shape, both being strip-shaped grooves formed by steel plates. The sealing gasket 2 is fixed on the left and right sides of the door panel 1, and is positioned between the door panel 1 and the passage door frame 6, and between the door panel 1 and the passage threshold 7. The sealing gasket 2 is V-shaped, made of rubber, and used for sealing the left and right sides of the door panel 1. The first sealing strip 3 is fixed in the first sealing groove 9, and the second sealing strip 4 is fixed in the second sealing groove 10. The fixing method is arbitrary and can be adhesive. The first sealing strip 3 and the second sealing strip 4 are both made of rubber and are used for sealing the top and bottom of the door panel 1, respectively. The first sealing strip 3 and the second sealing strip 4 have the same structural shape, and both have several cavities 17 inside. The cavities 17 facilitate the compression and deformation of the two sealing strips, which facilitates sealing. The first sealing strip 3 has an integral first V-shaped protrusion, and the second sealing strip 4 has an integral second V-shaped protrusion. The first V-shaped protrusion is in contact with the passage door frame 6. The second V-shaped protrusion makes contact with the passage threshold 7. The first and second V-shaped protrusions have the same structural shape, which facilitates the deformation and sealing of the two sealing strips after contact and compression with the passage door frame 6 and passage threshold 7. The structure of the two sealing strips can be divided into a main body 12 and a V-shaped protrusion 13. The main body 12 is strip-shaped (the overall cross-section is rectangular) and it is completely filled and fixed in the two strip-shaped sealing grooves. The V-shaped protrusion 13 is V-shaped (the overall cross-section is V-shaped or isosceles triangle) and it protrudes or is exposed outside the two sealing grooves, which facilitates the compression deformation of the two sealing strips and facilitates sealing. The passage door frame 6 and passage threshold 7 are both located at the entrance and exit of the ro-ro ship passage 15. Both are integral parts of the ro-ro ship passage 15 or the ro-ro ship passage equipment. The passage threshold 7 is an inclined flat plate that is fixed to the surface of the fixed ramp 16.

[0025] In this embodiment, stainless steel gaskets 8 are fixed to both the surface of the passage door frame 6 and the upper surface of the passage threshold 7, and the fixing method is arbitrary. The gaskets 8 are disposed between the door panel 1 and the passage door frame 6, and between the door panel 1 and the passage threshold 7. When the door panel 1 is closed, the sealing gasket 2, the first V-shaped protrusion, and the second V-shaped protrusion are pressed into contact with the gaskets 8. The stainless steel gaskets 8 facilitate the compression of the rubber, thus facilitating sealing.

[0026] In this embodiment, the door panel 1 is also equipped with a telescopic rod, a latch, and a slot 14, and the passage door frame 6 is equipped with a slot. The telescopic rod is an electric cylinder or a hydraulic cylinder, which is fixedly installed on the inner wall of the door panel 1, and the extended end of the telescopic rod is fixed to the latch. The latch is rectangular, the slot 14 is a square hole opened on the side of the door panel 1, and the slot is a rectangular groove opened on the side of the passage door frame 6. The structural shapes and arrangements of the latch, slot 14, and slot are compatible with each other. When the door panel 1 is closed, the telescopic rod extends, driving the latch to be inserted into the slot 14 and the slot in sequence, thereby locking and fixing the door panel 1 to the passage door frame 6. The telescopic rod, latch, slot 14, and slot are used to lock and fix the door panel 1 after it is closed, ensuring structural stability, and also to seal the middle of the door panel 1, enhancing the sealing effect.

[0027] In practical applications, the roll-on / roll-off ship passageway equipment is equipped with a drive device for rotating and opening / closing the door panel 1. This is not the object of protection in this application and will not be described further.

[0028] In practical applications, the ro-ro ship passage equipment (ro-ro ship passage 15, fixed ramp 16), door panel 1, passage door frame 6, and passage threshold 7 are existing technologies and will not be described in detail.

[0029] The airtightness principle of this embodiment is as follows: When the door panel 1 is closed, since the door panel 1 (channel door frame 6, channel threshold 7) is tilted, the door panel 1 can use its own weight to squeeze the sealing gasket 2, the first sealing strip 3, and the second sealing strip 4. At the same time, since the first sealing strip 3 and the second sealing strip 4 are provided with cavities 17, the first V-shaped protrusion deforms after it is squeezed and contacted with the channel door frame 6, and the second V-shaped protrusion deforms after it is squeezed and contacted with the channel threshold 7. This allows the top, sides, and bottom of the door panel 1 to be better sealed, resulting in excellent sealing performance.

[0030] The beneficial effects of this embodiment are as follows: the airtightness of this airtight door sealing structure is strong, safe, stable and reliable, and the overall structure is simple.

[0031] Example 2

[0032] As shown in Figures 1-3, an airtight door sealing structure for a roll-on / roll-off (Ro-Ro) ship passageway includes a door panel 1, a sealing gasket 2, a first sealing strip 3, a second sealing strip 4, an auxiliary sealing strip 5, a passageway door frame 6, and a passageway threshold 7. The door panel 1 has a conventional structure; its top is hinged to the Ro-Ro ship passageway 15, and its sides are respectively attached to the passageway door frame 6 and the passageway threshold 7. The door panel 1 is inclined at a 15-degree angle to the vertical direction, the passageway door frame 6 is also inclined at a 15-degree angle to the vertical direction, and the passageway threshold 7 is inclined at an angle to the horizontal direction. The structural shapes and arrangements of the door panel 1, the passageway door frame 6, and the passageway threshold 7 are all compatible with each other. The top side of the door panel 1 has a first sealing groove 9, the bottom side of the door panel 1 has a second sealing groove 10, and the middle side of the door panel 1 has an auxiliary sealing groove 11. The first sealing groove 9, the second sealing groove 10, and the auxiliary sealing groove 11 have the same shape, all being strip-shaped grooves formed by steel plates. The sealing gasket 2 is fixed on the left and right sides of the door panel 1. The sealing gasket 2 is located between the door panel 1 and the passage door frame 6, and between the door panel 1 and the passage threshold 7. The sealing gasket 2 is V-shaped and made of rubber, and is used for sealing the left and right sides of the door panel 1. The first sealing strip 3 is fixed in the first sealing groove 9, the second sealing strip 4 is fixed in the second sealing groove 10, and the auxiliary sealing strip 5 is fixed in the auxiliary sealing groove 11. The fixing method is arbitrary and can be glued. The first sealing strip 3, the second sealing strip 4, and the auxiliary sealing strip 5 are all made of rubber. The first sealing strip 3 and the second sealing strip 4 are used for sealing the top and bottom of the door panel 1, respectively, and the auxiliary sealing strip 5 is used to enhance the sealing of the middle part of the door panel 1. The first sealing strip 3 and the second sealing strip 4 have the same structural shape, and the auxiliary sealing strip 5 is similar in shape to the first sealing strip 3 or the second sealing strip 4. All three have several cavities 17 inside, which facilitate the compression and deformation of the three sealing strips and facilitate sealing. The first sealing strip 3 has an integral first V-shaped protrusion, and the second sealing strip 4 has an integral second V-shaped protrusion, which assists in sealing. The strip 5 is integrally provided with an auxiliary V-shaped protrusion. The first V-shaped protrusion and the auxiliary V-shaped protrusion are in contact with the channel door frame 6, and the second V-shaped protrusion is in contact with the channel threshold 7. The first V-shaped protrusion and the second V-shaped protrusion have the same shape. The auxiliary V-shaped protrusion is similar in shape to the first V-shaped protrusion or the second V-shaped protrusion. The three of them facilitate the deformation of the three sealing strips after contact and compression with the corresponding channel door frame 6 or channel threshold 7, which facilitates sealing. The structure of the three sealing strips can be divided into a main body 12 and a V-shaped protrusion 13. The main body 12 is strip-shaped (the cross-section is rectangular) and it is completely filled and fixed in the sealing grooves of the three strips. The V-shaped protrusion 13 is V-shaped (the cross-section is V-shaped or isosceles triangle) and it protrudes or is exposed outside the three sealing grooves. This facilitates the compression deformation of the three sealing strips and facilitates sealing. The passage door frame 6 and passage threshold 7 are both located at the entrance and exit of the ro-ro ship passage 15. Both are integral parts of the ro-ro ship passage 15 or the ro-ro ship passage equipment. The passage threshold 7 is an inclined flat plate that is fixed to the surface of the fixed ramp 16.

[0033] In this embodiment, stainless steel gaskets 8 are fixed to both the surface of the passage door frame 6 and the upper surface of the passage threshold 7, and the fixing method is arbitrary. The gaskets 8 are disposed between the door panel 1 and the passage door frame 6, and between the door panel 1 and the passage threshold 7. When the door panel 1 is closed, the sealing gasket 2, the first V-shaped protrusion, the second V-shaped protrusion, and the auxiliary V-shaped protrusion respectively press against the gasket 8. The stainless steel gasket 8 facilitates the pressing against the rubber, thus facilitating sealing.

[0034] In this embodiment, there are several auxiliary sealing strips 5 and auxiliary sealing grooves 11, and their quantity and arrangement are consistent, with both being regularly distributed on the door panel 1. There are four sets of each auxiliary sealing strip 5 and auxiliary sealing groove 11, with two sets spaced apart at the middle position on the left and right sides of the door panel 1; the auxiliary sealing strip 5 can be located inside the sealing gasket 2 or the sealing gasket 2 can be broken in the middle.

[0035] In this embodiment, the door panel 1 is also equipped with a telescopic rod, a latch, and a slot 14, and the passage door frame 6 is equipped with a slot. The telescopic rod is an electric cylinder or a hydraulic cylinder, which is fixedly installed on the inner wall of the door panel 1, and the extended end of the telescopic rod is fixed to the latch. The latch is rectangular, the slot 14 is a square hole opened on the side of the door panel 1, and the slot is a rectangular groove opened on the side of the passage door frame 6. The structural shapes and arrangements of the latch, slot 14, and slot are compatible with each other. When the door panel 1 is closed, the telescopic rod extends, driving the latch to be inserted into the slot 14 and the slot in sequence, thereby locking and fixing the door panel 1 to the passage door frame 6. The telescopic rod, latch, slot 14, and slot are used to lock and fix the door panel 1 after it is closed, ensuring structural stability, and also to seal the middle of the door panel 1, enhancing the sealing effect.

[0036] In practical applications, the roll-on / roll-off ship passageway equipment is equipped with a drive device for rotating and opening / closing the door panel 1. This is not the object of protection in this application and will not be described further.

[0037] In practical applications, the ro-ro ship passage equipment (ro-ro ship passage 15, fixed ramp 16), door panel 1, passage door frame 6, and passage threshold 7 are existing technologies and will not be described in detail.

[0038] The airtightness principle of this embodiment is as follows: When the door panel 1 is closed, since the door panel 1 (channel door frame 6, channel threshold 7) is tilted, the door panel 1 can use its own weight to squeeze the sealing gasket 2, auxiliary sealing strip 5, first sealing strip 3, and second sealing strip 4. At the same time, since the auxiliary sealing strip 5, first sealing strip 3, and second sealing strip 4 are all provided with cavities 17, the auxiliary V-shaped protrusion and the first V-shaped protrusion are deformed after being squeezed and contacted with the channel door frame 6, and the second V-shaped protrusion is deformed after being squeezed and contacted with the channel threshold 7. This allows the top, sides (middle), and bottom of the door panel 1 to be better sealed, resulting in excellent sealing performance.

[0039] The beneficial effects of this embodiment are as follows: By setting the auxiliary sealing strip 5 and the auxiliary V-shaped protrusion to press against the channel door frame 6, this structure can further enhance the sealing performance and achieve a better sealing effect. This airtight door sealing structure has strong airtightness, is safe, stable, and reliable, and has a simple overall structure.
