The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1 to 8, the preferred embodiment provides a non-powered split watertight side door, which comprises a door frame 1, two split door leaves 2, a driving mechanism 4 and a locking mechanism 5.
Because when the watertight port door opening is great, 2 weight of door leaf can be very big, and the inconvenient operation of the form of singly opening the door changes the port door into to open, and its weight of the operable door leaf of personnel 2 is less relatively, and saves cabin space to the open port door relative single open port door, does benefit to the arrangement of hull structural design and other equipment.
The two door leaves 2 are respectively installed on the doorframe 1 through hinges, the edge of the door leaf 2 is provided with a sealing strip 3, the contact part of the sealing strip 3 and the doorframe 1 is called a side sealing strip 31, and the contact part of the sealing strip 3 and the other door leaf is called a middle seam sealing strip 32, as shown in fig. 8.
It should be noted that the cross section of the side sealing strip 31 between the door leaf 2 and the door frame 1 is rectangular, an angle steel 21 is arranged on the side surface of the door leaf 2 corresponding to the convex edge 11 of the door frame 1, the side sealing strip 31 is embedded in the angle steel 21, and when the porthole door is closed, the convex edge 11 of the door frame 1 presses the side sealing strip 31 in the angle steel 21 to realize sealing.
The section of a middle seam sealing strip 32 positioned between two door leaves 2 is trapezoidal, a base plate 22 is arranged on a vertical plate of the side surface of one door leaf 2, pressing plates 23 are arranged at intervals on one sides of the base plates 22, and the middle seam sealing strip 32 is clamped between the base plates 22 and the pressing plates 23; set up diaphragm 24 on the side riser of another door leaf 2, be provided with flitch 25 on the diaphragm 24, one side interval of flitch 25 is provided with backup pad 26, and the centre joint sealing strip 32 dress is pressed from both sides between flitch 25 and backup pad 26, and the centre joint sealing strip 32 of two door leaves 2 supports with the inclined plane form cooperation and leans on, realizes sealedly.
The watertight performance of the split type side port is a key index, and the watertight performance of the side port can reach 0.06MPa by the sealing mode used by the side port, so that the side port can meet the requirements of various ships at present.
The driving mechanism 4 comprises a base 41 arranged on the door leaf 2, a rotating shaft 42 is arranged on the base 41, and the rotating shaft 42 adopts a planetary gear speed reducing structure to link the locking mechanism 5.
Because the watertight port door is high in tightness requirement, the rubber strip is large in compression amount, and particularly when the opening is large, the compression force is positively correlated with the length of the rubber strip. The compressive force here is converted through drive arrangement by the manpower, adopts the drive mode of planet wheel, can be so that the space that occupies door leaf 2 is little, can not influence inner structure's enhancement, can design the drive ratio according to arranging of 2 gusset of door leaf simultaneously, and the drive ratio can be tens of to even be greater than one hundred, especially adapted big open-ended porthole.
The planet wheel speed reducing structure is shown in fig. 7, a plurality of gear shafts 43 are arranged on the base 41 and distributed on the outer ring of the rotating shaft 42, a first gear 44 and a driving hand wheel 45 are arranged on the rotating shaft 42, the rotating shaft 42 and the first gear 44 are driven to rotate by the driving hand wheel 45, a second gear 46 is sleeved on the gear shaft 43, the second gears 46 are simultaneously in meshing transmission with the first gear 44 at the center, a gear disc 47 capable of rotating relatively is further sleeved on the rotating shaft 42, the gear disc 47 is simultaneously in meshing transmission with the second gears 46, and a connecting rod shaft 48 connected with the locking mechanism 5 is eccentrically arranged on the gear disc 47.
The locking mechanism 5 adopts a wedge locking or bolt locking mode to lock the two door leaves 2 in a door closing state, the embodiment is exemplified by wedge locking, and specifically includes a wedge shaft 51 installed on the door leaf 2, a plurality of wedge shafts 51 are distributed on the inner side edge of the door leaf 2, a locking wedge 52 is arranged on the wedge shaft 51, a wedge block 53 is arranged on the doorframe 1 and the other door leaf 2 corresponding to each locking wedge 52, each locking wedge 52 extends out or retracts back to the side edge of the door leaf 2 along with the rotation of the wedge shaft 51, so as to be matched with the corresponding wedge block 53 for locking or unlocking, the plurality of locking wedges 52 are connected through a connecting rod 54 to rotate synchronously, and a supporting rod 55 connected with the driving mechanism 4 is arranged on the connecting rod 54.
Further, the wedge 53 is fixed to the door frame 1 or the door leaf 2 by a bolt, and a gasket 56 for adjusting the height of the wedge 53 is interposed, and the amount of compression of the weather strip 3 when the door is closed is changed by adjusting the number of the gaskets 56, thereby ensuring the sealing performance.
The opening and closing angle of the two door leaves 2 relative to the door frame 1 is 0-90 degrees, and when the porthole door is closed, the outer plates of the door frame 1 and the outer plates of the door leaves 2 are all parallel and level to or consistent with the line type of the outer plate of the ship body, and the appearance is good.
In addition, the watertight port door further comprises a buffer 6, a door stopper 7 and a door hook 8.
The both ends of buffer 6 are connected the medial surface and the hull of door leaf 2 respectively for make door leaf 2 steadily open and shut, and buffer 6 is preferred hydraulic damper or air spring, because manual formula porthole is inconvenient when boats and ships rock and operate, and buffer 6 helps even if boats and ships rock door leaf 2 also can steadily rotate.
The door stopper 7 is fixed on the ship body, acts on the inner side surface of the door leaf 2 and is used for limiting the opening angle of the door leaf 2.
The door hook 8 is fixed on the ship body, and the inner side surface of the door leaf 2 is provided with a fixing hole 27 which is matched with the door hook 8 to be inserted and used for locking the position of the door leaf 2.
And (3) closing state: as shown in fig. 1, when the side door is closed, the outer plates of the door frame 1 and the door leaf 2 are all level with or consistent with the line type of the outer plate of the ship body; as shown in fig. 2, the locking wedge 52 of the locking device is pressed against the wedge 53; as shown in fig. 5 and 6, the convex edge 11 of the doorframe 1 presses the side sealing strip 31 with a rectangular cross section, and the center sealing strips 32 of the two door leaves 2 are kept in a pressed state.
And (3) opening process: the driving hand wheel 45 on the door leaf 2 is rotated to link the rotating shaft 42, the first gear 44, the second gear 46 and the gear disc 47 to rotate, and then the connecting rod 54 of the locking mechanism 5 is driven by the connecting rod shaft 48 to drive the locking wedge 52 to rotate, so that the contact surface of the locking wedge 52 and the wedge 53 is separated, and the door leaf 2 is opened around the hinge. Since the two door leaves 2 are also locked by the wedge, attention needs to be paid to the opening sequence of the two door leaves 2.
An open state: the door leaf 2 is opened to contact with the door stopper 7, the buffer 6 is contracted to realize stable opening in the process, and then the door hook 8 is inserted into the fixing hole 27 on the door leaf 2 to form locking, as shown in fig. 4.
To sum up, foretell unpowered open watertight porthole adopts unpowered operation form, and the design of cooperation planet wheel speed reduction can be applied to big opening porthole, and the labour saving operation, the shared door leaf space is little simultaneously, does not hinder door leaf intensity design, and is with low costs, and the reliability is high, and the maintenance of being convenient for has guaranteed sufficient sealing performance, has satisfied the design requirement of boats and ships porthole door.
