Description

Technical Field

[0001] The present invention belongs to the technical field of translational doors, and specifically relates to a side-opening translational weathertight door for ships. Background Art

[0002] Ship weathertight doors are core components for ensuring the watertightness of the hull and the safety of crew members, and need to withstand the erosion of wind, waves, rain, and salt spray under harsh sea conditions.

[0003] Currently, the design of ship weathertight doors mainly focuses on hinge-type, sliding-type, or hydraulic drive-type structures. Their core functions are to ensure the weathertightness of the cabin and the convenience of operation. However, there are many problems in specific use: Hinge-type weathertight doors: Hinge-type side-opening doors need to open outward or inward, occupying deck or cabin space and affecting the efficiency of cargo handling and personnel passage.

[0004] Sliding-type weathertight doors: The upper door body that slides up and down controls the opening and closing of the inlet and outlet. Although it has the advantage of saving effort, it is difficult to detect water leakage in time after the sealing ring wears, and serious water leakage accidents are likely to occur in extreme weather. Moreover, the vertical sliding door relies on the top track, has high requirements for the height of the cabin, and the door leaf is easily damaged by the impact of sea waves when retracted.

[0005] Therefore, the present invention provides a side-opening translational weathertight door for ships. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A side-opening translational weathertight door for ships according to the present invention includes a weathertight door frame body. The weathertight door frame body includes a door frame and a door leaf. The door leaf is arranged outside the door frame, and the door leaf can be opened in a translational manner outside the door frame. Two groups of fixed frames are fixedly connected to the inner side of the weathertight door frame body. There are four fixed frames, which are designed to be distributed in two pairs, one above the other. A rotating shaft is rotatably arranged inside each fixed frame. An L-shaped support rod is fixedly installed on the outer peripheral surface of the rotating shaft. The side of the L-shaped support rod away from the rotating shaft is connected to the side wall of the door leaf. The rotating shaft is connected to the output end of an external motor; When a traditional hinge door is opened, it needs to be rotated to open, which occupies relatively more space. While for the side-opening translational door, it first swings out parallel to the outside of the door frame to disengage from the door frame, and then horizontally translates the door leaf, reducing the obstruction of the passage. It is especially suitable for narrow passages or scenarios where luxury passenger ships have high requirements for aesthetics.

[0008] Preferably, four hinge brackets are fixedly installed on the side wall of the door leaf, and the end of each L-shaped support rod away from the rotating shaft penetrates through the inside of the hinge bracket; during operation, as shown in the attached drawings, hinge brackets are provided at the connection between the end of each L-shaped support rod and the door leaf, which can further improve the smoothness of the door leaf when it is opened.

[0009] Preferably, two groups of handle panels are installed on the surface of the door leaf. The two groups of handle panels are symmetrically designed up and down on the surface of the door frame. Multiple groups of locking pins are provided on the sides of the two groups of handle panels. The end of each group of locking pins away from the handle panel penetrates through the door frame and the inside of the door leaf. Guide sleeves are installed on the surfaces of the door leaf and the door frame, and the locking pins penetrate through the inside of the guide sleeves.

[0010] Preferably, outer handles one are rotatably provided on both sides of the handle panel, and an outer handle two is provided on the outer side of the door leaf. The outer handles one are rotatably provided on the two side walls of the handle panel through a central shaft, and two corresponding outer handles one are jointly connected to the two ends of the central shaft; during operation, the outer handle two is designed so that when the external controller is damaged, that is, when the rotating shaft cannot be driven, the staff can pull the door leaf to rotate along the L-shaped support rod and the rotating shaft through the outer handle two. In this way, the door can be manually opened during power failure or emergency, improving the safety of human-computer interaction and reducing the accident risk; Furthermore, the outer handle one is designed. The staff can rotate the outer handle one to drive the central shaft to rotate, which is convenient for the subsequent movement of the locking pin, and thus convenient for fixing and opening the door leaf.

[0011] Preferably, a rotating arm is fixedly installed on the outer peripheral surface of the central shaft. Three extension shafts are provided on the outer peripheral surface of the rotating arm. A connecting slider is installed on the side of the locking pin close to the rotating arm. The rotating arm is hinged to the connecting slider through the extension shaft.

[0012] Preferably, multiple groups of panel guide rails are installed on the side wall of the handle panel. The side of the connecting slider is slidably arranged on the surface of the panel guide rail. Grooves adapted to the connecting slider are provided on the surface of the panel guide rail. Multiple groups of headrest sleeves are provided on the side wall of the door leaf. The side of the locking pin away from the handle panel penetrates through the inside of the headrest sleeve; during operation, when the connecting slider moves following the hinged rotating arm, the connecting slider will move outside the panel guide rail. Under the mutual limitation of the connecting slider and the panel guide rail, it can be ensured that the connecting slider moves on the same axis, so it is convenient for the locking pin to pass through the guide sleeve and the inside of the headrest sleeve, and the operation is relatively convenient and fast.

[0013] Preferably, a plurality of groups of sealing strips are provided between the door leaf and the door frame. A memory sponge is provided on the back of the sealing strip. A water guide pipe is provided inside the door frame, and the water guide pipe is externally connected to the deck drainage system. The provision of multiple groups of sealing strips can improve the wind and rain sealing performance. Moreover, under the action of the memory sponge, the gap caused by temperature change or wear can be automatically compensated. The provision of the water guide pipe can quickly drain the accumulated water into the deck drainage system. At the same time, when the door leaf and the door frame are in the closed state, under the uniform pressure of the door leaf on the door frame, the sealing strip can be fully compressed, improving the sealing reliability and also extending the service life of the sealing strip.

[0014] Preferably, a threshold is provided at the bottom of the door leaf. A retention chamber is provided inside the threshold. A floating ball is provided inside the retention chamber. A lifting unit is provided above the threshold, and the lifting unit is used to lift the threshold. During operation, the design of the threshold is beneficial to support the weight of the door leaf when it is closed and forms a key waterproof barrier. It is independent of the bottom side of the door leaf, which is beneficial to further improve the waterproof effect of this airtight door. Moreover, through the action of the lifting unit, the height of the threshold can be adaptively adjusted according to the height of the water entering the outer cabin, which is beneficial to further waterproofing.

[0015] Preferably, the lifting unit includes an adjustment sill slidably provided above the threshold. A rotating gear is rotatably provided inside the threshold. A rack is slidably provided inside the threshold. The rack is meshed with the rotating gear. The upper end surface of the rack is connected to the lower end surface of the adjustment sill. A visual sensor is provided inside the threshold, and the visual sensor is used to monitor the height of the floating ball. During operation, the water in the cabin will enter the bottom through the retention chamber, and the floating ball will float under the action of buoyancy. The height of the floating ball is observed in real time through the visual sensor. If the height of the floating ball is too high, a signal will be transmitted to the controller, and the controller will control the rotating gear to rotate. The rotating gear drives the rack to move, and the rack drives the adjustment sill to move upward. This is convenient for further waterproofing, more flexible than the traditional fixed threshold, and the self-locking property of the rack and the rotating gear improves the stability of the adjustment sill itself.

[0016] Preferably, a sealed frame adapted to the rotating gear is provided inside the threshold. Such a design has a certain protective effect on the rotating gear. Moreover, it should also be noted that the threshold cooperates with the sealing strip at the bottom of the door leaf, and the sealing strip at the bottom of the door leaf can adapt to height changes. Specifically, the sealing strip can be a telescopic structure.

[0017] The beneficial effects of the present invention are as follows: 1. For the side-opening and translational weathertight door of a ship described in the present invention, by first moving laterally and then translating the door leaf horizontally through side-opening and translational movement, the occlusion of the passage is reduced, which is especially suitable for narrow passages or scenarios with high aesthetic requirements on luxury passenger ships.

[0018] 2. For the side-opening and translation type weathertight door of a ship according to the present invention, the staff can pull the door leaf to rotate along the L-shaped support rod and the rotating shaft through the outer handle II, so that the door can be manually opened during power failure or emergency, improving the safety of human-computer interaction and reducing the accident risk.

[0019] 3. For the side-opening and translation type weathertight door of a ship according to the present invention, when the central shaft rotates, the central shaft will drive the rotating arm outside it to rotate at the same time. The rotating arm will drive the connecting slider hinged to it to move, and the connecting slider will drive the locking pin to move. Then the locking pin will move inside the guide sleeve. With such a design, not only can the door leaf be quickly opened and closed, but also under the pressure of multiple locking pins, the impact resistance of the door leaf itself is improved, making the pressure on the door leaf and the door frame uniform and improving the service life of the door leaf and the door frame.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 11 As shown, a side-opening, sliding, weathertight door for ships according to an embodiment of the present invention comprises a tight door frame 1, wherein the tight door frame 1 comprises a door frame 2 and a door leaf 3, wherein the door leaf 3 is arranged on the outside of the door frame 2, and the door leaf 3 can be opened in a translational manner on the outside of the door frame 2, and two groups of fixed frames 4 are fixedly connected to the inner side of the tight door frame 1, wherein four fixed frames 4 are provided and are distributed in pairs up and down, and a rotating shaft 401 is rotatably provided inside each of the fixed frames 4, and an L-shaped support rod 5 is fixedly installed on the outer circumference of the rotating shaft 401, and the side of the L-shaped support rod 5 away from the rotating shaft 401 is connected to the side wall of the door leaf 3, and the rotating shaft 401 is connected to the output end of the external motor; When working, the ship's side-opening and sliding weathertight door is a special door design that combines side opening and translation. It is mainly used for the entrance and exit of closed superstructures or deckhouses of ships such as passenger ships and cargo ships. Traditional hinged doors need to be rotated to open, which takes up more space. However, the side-opening translation type first separates the door frame 2 parallel to the outside, and then slides the door leaf 3 horizontally, reducing obstruction to the passage. It is especially suitable for narrow passages or luxury passenger ships where high aesthetic requirements are required. Refer to the attached Figure 3 As shown, this figure shows the state diagram when the door leaf 3 is combined with the door frame 2, that is, the state diagram when the door frame body 1 is closed. When it is necessary to open it, the four sets of rotating shafts 401 are controlled to rotate simultaneously by the external controller. The four sets of rotating shafts 401 drive the L-shaped support rods 5 and the door leaf 3 to first separate from the door frame 2, and then move to one side of the door frame 2 in a translational manner, that is, from the attached Figure 3 Move to the attached Figure 2 The location shown, Figure 2It shows a schematic structural diagram when the door leaf 3 is located on the side of the door frame 2, that is, the state diagram when the secret door frame body 1 is opened; through the design of four groups of rotating shafts 401, the smoothness of the opening and closing of the door leaf 3 can be improved, making it more convenient and fast to use. When the door leaf 3 and the door frame 2 are in the closed state, under the uniform pressure of the door leaf 3 on the door frame 2, the sealing member can be fully compressed, improving the sealing reliability.

[0025] Four hinge frames 6 are fixedly installed on the side wall of the door leaf 3, and the end of each L-shaped support rod 5 far from the rotating shaft 401 penetrates into the inside of the hinge frame 6; during operation, refer to the attached Figure 2 As shown, hinge frames 6 are provided at the connection between the end of each L-shaped support rod 5 and the door leaf 3, which can further improve the smoothness of the door leaf 3 when it is opened.

[0026] Two groups of handle panels 7 are installed on the surface of the door leaf 3. The two groups of handle panels 7 are symmetrically designed up and down on the surface of the door frame 2. Multiple groups of locking pins 8 are arranged on the sides of the two groups of handle panels 7. The end of each group of locking pins 8 far from the handle panel 7 penetrates into the inside of the door frame 2 and the door leaf 3. Guide sleeves 9 are installed on the surfaces of the door leaf 3 and the door frame 2, and the locking pins 8 penetrate into the inside of the guide sleeves 9. During operation, refer to the attached Figure 1 and Figure 3 As shown, when the secret door frame body 1 is closed, at this time, multiple groups of locking pins 8 located outside the handle panel 7 all penetrate into the guide sleeves 9 on the surfaces of the door leaf 3 and the door frame 2. Since multiple groups of locking pins 8 are provided on the upper and lower sides of the door frame 2, the stability of the door leaf 3 outside the door frame 2 can be improved when the secret door frame body 1 is closed. In this way, the impact resistance of the door leaf 3 and the door frame 2 can be improved, and it can ensure that each part of the door leaf 3 is evenly stressed when it is closed, improving safety.

[0027] Outer handles one 10 are rotatably arranged on both sides of the handle panel 7. An outer handle two 301 is arranged outside the door leaf 3. The outer handles one 10 are rotatably arranged on the two side walls of the handle panel 7 through central shafts 101. Two corresponding outer handles one 10 are commonly connected to the two ends of the central shaft 101; during operation, the outer handle two 301 is designed so that when the external controller is damaged, that is, when the rotating shaft 401 cannot be driven, the staff can pull the door leaf 3 to rotate along the L-shaped support rod 5 and the rotating shaft 401 through the outer handle two 301. In this way, the door can be manually opened during power failure or in an emergency, improving the safety of human-computer interaction and reducing the accident risk; Furthermore, the outer handle one 10 is designed. The staff can rotate the outer handle one 10 to drive the central shaft 101 to rotate, thereby facilitating the subsequent movement of the locking pin 8, and thus facilitating the fixing and opening of the door leaf 3.

[0028] A rotating arm 11 is fixedly installed on the outer peripheral surface of the central axis 101. Three extension shafts are arranged on the outer peripheral surface of the rotating arm 11. A connecting slider 12 is installed on one side of the locking pin 8 close to the rotating arm 11. The rotating arm 11 is hinged to the connecting slider 12 through the extension shaft. During operation, refer to the appendix Figure 4 and Figure 7 As shown, when the central axis 101 rotates, the central axis 101 will drive the rotating arm 11 outside it to rotate at the same time. The rotating arm 11 will drive the connecting slider 12 hinged to it to move. The connecting slider 12 will drive the locking pin 8 to move. After that, the locking pin 8 will move inside the guide sleeve 9. With such a design, not only can the door leaf 3 be quickly opened and closed, but also under the pressure of multiple locking pins 8, the impact resistance of the door leaf 3 itself is improved, so that the pressures on the door leaf 3 and the door frame 2 are both uniform, and the service lives of the door leaf 3 and the door frame 2 are increased; A plurality of panel guide rails 13 are installed on the side wall of the handle panel 7. The side of the connecting slider 12 is slidably arranged on the surface of the panel guide rail 13. Grooves adapted to the connecting slider 12 are formed on the surface of the panel guide rail 13. A plurality of tie head sleeves 14 are arranged on the side wall of the door leaf 3. One side of the locking pin 8 away from the handle panel 7 penetrates through the inside of the tie head sleeve 14. During operation, when the connecting slider 12 moves following the hinged rotating arm 11, the connecting slider 12 will move outside the panel guide rail 13. Under the mutual limitation of the connecting slider 12 and the panel guide rail 13, it can be ensured that the connecting slider 12 moves on the same axis. Therefore, it is convenient for the locking pin 8 to pass through the inside of the guide sleeve 9 and the tie head sleeve 14, and the operation is relatively convenient and fast.

[0029] A plurality of sealing strips 15 are arranged between the door leaf 3 and the door frame 2. A memory sponge is arranged on the back of the sealing strip 15. A water guide pipe is arranged inside the door frame 2, and the water guide pipe is externally connected to the deck drainage system; By arranging a plurality of sealing strips 15, the wind and rain sealing performance can be improved. Moreover, under the action of the memory sponge, the gaps caused by temperature changes or wear can be automatically compensated. By arranging the water guide pipe, the accumulated water can be quickly discharged into the deck drainage system. At the same time, when the door leaf 3 and the door frame 2 are in the closed state, under the uniform pressure of the door leaf 3 on the door frame 2, the sealing strip 15 can be fully compressed, improving the sealing reliability and also increasing the service life of the sealing strip 15.

[0030] A threshold 16 is arranged at the bottom of the door leaf 3. A retention chamber 17 is arranged inside the threshold 16. A floating ball 18 is arranged inside the retention chamber 17. A lifting unit is arranged above the threshold 16, and the lifting unit is used to lift the threshold 16; During operation, a threshold 16 is designed, which is beneficial to supporting the weight of the door leaf 3 when it is closed and forms a key waterproof barrier. It is independent of the bottom side of the door leaf 3, which is beneficial to further improving the waterproof effect of this secret door. Moreover, through the action of the lifting unit, the height of the threshold 16 can be adaptively adjusted according to the height of the water entering the outer cabin, which is beneficial to further waterproofing. The retention chamber 17 and the floating ball 18 are designed, which can facilitate the subsequent increase in the height of the threshold 16 with the change of the external water level.

[0031] The lifting unit includes an adjustment sill 19 slidably arranged above the threshold 16. A rotating gear 20 is rotatably arranged inside the threshold 16. A rack 21 is slidably arranged inside the threshold 16. The rack 21 is meshed and connected with the rotating gear 20. The upper end surface of the rack 21 is connected to the lower end surface of the adjustment sill 19. A visual sensor 22 is arranged inside the threshold 16. The visual sensor 22 is used to monitor the height of the floating ball 18. During operation, the water in the cabin will enter its bottom through the retention chamber 17, and the floating ball 18 will float under the action of buoyancy. The height of the floating ball 18 is observed in real time through the visual sensor 22. If the height of the floating ball 18 is too high, a signal will be transmitted to the controller, and the rotating gear 20 will be controlled by the controller to rotate. The rotating gear 20 drives the rack 21 to move, and the rack 21 drives the adjustment sill 19 to move upward. This is convenient for further waterproofing, which is more flexible than the traditional fixed threshold 16. Moreover, due to the self-locking property of the rack 21 and the rotating gear 20 itself, the stability of the adjustment sill 19 is improved.

[0032] A sealed frame adapted to the rotating gear 20 is arranged inside the threshold 16. Such a design has a certain protective effect on the rotating gear 20. Moreover, it should also be noted that the threshold 16 cooperates with the sealing strip 15 at the bottom of the door leaf 3, and the sealing strip 15 at the bottom of the door leaf 3 can adapt to height changes. Specifically, the sealing strip 15 can be a telescopic structure.

[0033] During operation, when a traditional hinge door is opened, it needs to be rotated to open, which occupies more space. While for the side-opening and translating type, it first swings out parallel to the outside to disengage from the door frame 2, and then laterally translates the door leaf 3, reducing the occlusion of the passage. It is especially suitable for narrow passages or scenarios with high aesthetic requirements on luxury passenger ships. Refer to the attachment Figure 3 As shown, this figure shows the state diagram when the door leaf 3 is combined with the door frame 2, that is, the state diagram when the secret door frame 1 is closed. When it needs to be opened, four groups of rotating shafts 401 are controlled to rotate simultaneously through an external controller. The four groups of rotating shafts 401 drive the L-shaped support rods 5 and the door leaf 3 to first disengage from the door frame 2, and then translate to one side of the door frame 2, that is, from the attachment Figure 3 Move to the attachment Figure 2 Shown position, Figure 2It shows a schematic structural diagram when the door leaf 3 is located on the side of the door frame 2, that is, the state diagram when the secret door frame body 1 is opened; through the design of four groups of rotating shafts 401, the smoothness of opening and closing the door leaf 3 can be improved, making it more convenient and fast to use; Refer to the appendix Figure 1 and Figure 3 As shown, when the secret door frame body 1 is closed, at this time, multiple groups of locking pins 8 located outside the handle panel 7 all penetrate through the guide sleeves 9 on the surfaces of the door leaf 3 and the door frame 2. Since multiple groups of locking pins 8 are arranged on the upper and lower sides of the door frame 2, the stability of the door leaf 3 located outside the door frame 2 when the secret door frame body 1 is closed can be improved. In this way, the impact resistance of the door leaf 3 and the door frame 2 can be improved, and it can ensure that each part of the door leaf 3 is evenly stressed when closed, improving safety; the outer handle two 301 is designed, so that when the external controller is damaged, that is, when the rotating shaft 401 cannot be driven, the staff can pull the door leaf 3 to rotate along the L-shaped support rod 5 and the rotating shaft 401 through the outer handle two 301. In this way, the door can be manually opened during power failure or emergency, improving the safety of human-computer interaction and reducing the accident risk; Refer to the appendix Figure 4 and Figure 7 As shown, when the central shaft 101 rotates, the central shaft 101 will simultaneously drive the rotating arm 11 on its outer side to rotate. The rotating arm 11 will drive the connecting slider 12 hinged to it to move. The connecting slider 12 will drive the locking pin 8 to move. After that, the locking pin 8 will move inside the guide sleeve 9. With this design, not only can the door leaf 3 be quickly opened and closed, but also under the pressure of multiple locking pins 8, the impact resistance of the door leaf 3 itself can be improved, making the pressure on the door leaf 3 and the door frame 2 uniform, and improving the service life of the door leaf 3 and the door frame 2; when the connecting slider 12 moves following the hinged rotating arm 11, the connecting slider 12 will move outside the panel guide rail 13. Under the mutual limitation of the connecting slider 12 and the panel guide rail 13, it can ensure that the connecting slider 12 moves on the same axis, so it is convenient for the locking pin 8 to pass through the guide sleeve 9 and the inside of the ferrule 14, and the operation is relatively convenient and fast; Multiple groups of sealing strips 15 are provided, which can improve the wind and rain sealing performance. Moreover, under the action of the memory sponge, it can automatically compensate for the gaps caused by temperature changes or wear and tear. A water guide pipe is provided, which can quickly drain the accumulated water into the deck drainage system. At the same time, when the door leaf 3 and the door frame 2 are in the closed state, under the uniform pressure of the door leaf 3 on the door frame 2, the sealing strip 15 can be fully compressed, improving the sealing reliability and also the service life of the sealing strip 15; Water passing through the cabin will enter its bottom through the retention chamber 17, and the float ball 18 will float under the action of buoyancy. The height of the float ball 18 is observed in real time through the visual sensor 22. If the height of the float ball 18 is too high, a signal will be transmitted to the controller, and the controller will control the rotation of the rotating gear 20. The rotating gear 20 drives the rack 21 to move, and the rack 21 drives the adjustment sill 19 to move upward. This makes it more convenient for further waterproofing, which is more flexible than the traditional fixed sill 16. Moreover, due to the self-locking properties of the rack 21 and the rotating gear 20 themselves, the stability of the adjustment sill 19 is improved.
