Description

Technical Field

[0001] This application relates to the technical field of hatch covers, and in particular to a quick-opening and closing embedded hatch cover. Background Technology

[0002] Ships typically have hatches on their open decks that connect to their internal compartments. These hatches are covered to prevent people from falling into them or water from the ship's deck from entering them during navigation.

[0003] Currently, a raised ring-shaped part is usually installed on the hatch to block the hatch and prevent water on the deck from flowing directly into the hatch. Then, a hatch cover is installed on the ring-shaped part to seal the hatch.

[0004] However, because the hatch cover and the ring-shaped part both bulge upwards, an upward-bulging structure appears on the deck, which hinders the crew's movement on the deck.

[0005] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0006] In order to prevent the hatch cover from being positioned so as not to cause an upward protrusion on the deck and to make it less likely to affect the crew's movement on the deck, this application provides a quick-opening and closing embedded hatch cover.

[0007] This application provides a quick-opening and closing embedded hatch cover, which adopts the following technical solution:

[0008] A quick-opening and closing recessed hatch cover includes a raised edge disposed within the hatch, a cover body disposed above the raised edge, and a locking assembly for defining the position of the cover body. The cover body is disposed within the hatch and closes the hatch. The upper end of the cover body is flush with the deck. The locking assembly includes a plurality of locking rods slidably disposed on the cover body, a first locking member and a second locking member for pushing the locking rods to move. The first locking member and the second locking member are connected and both can drive the locking rods to move. The locking rods can pass through the raised edge. The first locking member and the second locking member are respectively disposed at both ends of the cover body, and the locking rods are disposed at the end of the cover body closer to the interior of the hatch.

[0009] By adopting the above technical solution, the flange is set inside the hatch, and then the cover is set above the flange and connected to the hatch by the locking assembly, so that the upper surface of the cover is flush with the upper surface of the deck, thereby making it less likely for bulges to occur on the deck and keeping the upper surface of the deck level, so that the crew is less affected when walking.

[0010] Optionally: The first locking component includes a drive disc rotatably connected to the end face of the cover and a handwheel connected to the drive disc. One end of each locking rod is rotatably connected to the drive disc, and the connection position between the locking rod and the drive disc is circumferentially arranged around the axis of the drive disc.

[0011] By adopting the above technical solution, the drive disc rotates, thereby causing the locking rod to move towards the inner wall of the hatch, so that the locking rod can be inserted into the protruding edge, thereby simultaneously driving multiple locking rods to move and locking the cover to the hatch.

[0012] Optionally: The end face of the cover with the drive disc is provided with a plurality of guide blocks, and the guide blocks are provided with guide grooves. The locking rod slides through the guide grooves, and the diameter of the guide grooves is larger than the diameter of the locking rods.

[0013] By adopting the above technical solution, the locking rod can pass through the guide groove even when it does not move along its own axis, thereby guiding the locking rod towards the convex edge. This allows the locking rod to align with and be inserted into the hole on the convex edge for inserting the locking rod, making the locking process of the locking rod more convenient. At the same time, the guide groove will not affect the normal movement of the locking rod.

[0014] Optionally: The guide block is provided with a limiting member that limits the position of the locking rod. The limiting member passes through the guide groove and abuts against the side wall of the locking rod away from the cover.

[0015] By adopting the above technical solution, the wobbling of the locking rod in the direction parallel to the axis of the drive disc is limited by the limiting component, thereby limiting the relative position between the locking rod and the cover, so that after the cover is placed on the convex edge, the locking rod can be better aligned with the hole on the convex edge for the locking rod to pass through.

[0016] Optionally, the second locking element includes a rotating disk rotatably connected to the cover and a handle for driving the rotating disk to rotate. The rotating disk is disposed on the end face of the cover away from the first locking element, and the rotating disk and the driving disk are connected by a rotating shaft to rotate synchronously.

[0017] By adopting the above technical solution, both the first locking member and the second locking member can drive the locking rod to move, so that the locking rod can move at both ends of the cover, making the opening and closing of the cover more convenient.

[0018] Optionally: A rotating groove is provided on the end face of the cover away from the first locking member, the rotating disk is completely embedded in the rotating groove, a receiving groove is provided on the rotating groove, and the handle is rotatably connected to the receiving groove and can be completely sunk into the receiving groove.

[0019] By adopting the above technical solution, when the handle is not needed, it can be rotated toward the receiving groove so that the handle is completely sunk into the receiving groove, so that there is no upward protrusion on the plate surface, making it less likely to affect the crew's movement on the deck. When it is necessary to drive the rotating disc to rotate, the handle can be rotated upward so that force can be applied to the handle to drive the rotating disc to rotate, making the movement of the locking rod better controlled.

[0020] Optionally: A water-retaining groove is provided on the upper end face of the convex edge along its contour.

[0021] By adopting the above technical solution, when water on the deck moves toward the hatch, the water will first flow into the water-blocking channel, thus preventing the water from flowing directly into the hatch and into the cabin.

[0022] Optionally: A sealing strip is provided along the outer contour of the end face of the cover where the first locking member is provided, and the sealing strip abuts against the upper end of the protrusion.

[0023] By adopting the above technical solution, the gap between the cover and the raised edge is filled by the sealing strip, so that water is not easy to flow into the compartment from the gap between the cover and the raised edge, and the cover can stably seal the hatch.

[0024] Optionally: A lifting groove is provided on the end face of the cover where the second locking member is provided, and a lifting member for applying force is provided in the lifting groove.

[0025] By adopting the above technical solution, after rotating the handle to separate the locking rod from the convex edge, the cover can be taken out from the hatch by grasping the lifting part and applying force to the lifting part. There is a position where force can be applied directly when taking the cover out from the hatch inlet, which makes the movement of the cover more convenient.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Place the flange inside the hatch, then place the cover above the flange and connect the cover to the hatch using the locking assembly, so that the upper surface of the cover is flush with the upper surface of the deck, thereby preventing bulges from forming on the deck and keeping the upper surface of the deck level, thus making it less likely for crew members to be affected when walking.

[0028] 2. When the handle is not needed, it can be rotated into the receiving groove so that the handle is completely submerged in the receiving groove, so that there is no upward protrusion on the plate surface, making it less likely to affect the crew's movement on the deck. When it is necessary to drive the rotating plate, the handle can be rotated upward to apply force to the handle and drive the rotating plate to rotate, making the movement of the locking rod easier to control.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a quick-opening and closing embedded hatch cover, such as Figure 1 and Figure 2 As shown, the device includes a flange 1 disposed within the hatch, a cover 2 covering the flange 1, and a locking assembly 3 for limiting the position of the cover 2. The flange 1 is disposed along the inner wall of the hatch, and the upper end of the flange 1 is lower than the upper end surface of the deck where the hatch is located. The cover 2 is disposed within the hatch and abuts against the upper end surface of the flange 1. A certain gap is left between the outer wall of the cover 2 and the inner wall of the hatch, and the upper end surface of the cover 2 is flush with the upper end of the deck where the hatch is located.

[0034] The locking assembly 3 includes four locking rods 31 slidably disposed on the end face of the cover 2 near the hatch, a first locking member 32 and a second locking member 33 for moving the locking rods 31. The first locking member 32 is disposed on the end face of the cover 2 near the hatch, and the second locking member 33 is disposed on the end face of the cover 2 near the deck. The four locking rods 31 are respectively disposed perpendicular to the four side walls of the cover 2, and the edge of the locking rod 31 near the end face of the flange 1 is chamfered. Locking grooves 11 are provided on the four inner walls of the flange 1. The four locking rods 31 can be respectively inserted into the corresponding locking grooves 11, thereby making the cover 2 stably close the hatch.

[0035] like Figure 2As shown, the first locking element 32 includes a drive disc 321 rotatably connected to the end face of the cover 2 and a handwheel 322 connected to the drive disc 321. The rotation axis of the drive disc 321 passes through the center of the cover 2, and a gap is left between the drive disc 321 and the cover 2. The handwheel 322 is coaxially mounted on the end face of the drive disc 321 away from the cover 2, and the handwheel 322 can rotate synchronously with the drive end. The ends of the locking rods 31 away from the flange 1 are all rotatably connected to the drive disc 321. The rotation axes of the locking rods 31 and the drive disc 321 are parallel to the rotation axis of the drive disc 321 itself. During the rotation of the drive disc 321, the locking rods 31 can be driven to insert or disengage from the locking groove 11, thereby realizing the simultaneous driving of four locking rods 31.

[0036] Four guide blocks 21 are also provided on the end face of the cover 2 where the first driving component is located. The four guide blocks 21 are respectively located near the four side walls of the cover 2. A guide groove 222 is provided through the end face of the guide block 21 near the driving disk 321. The locking rod 31 can move through the guide groove 222. The diameter of the guide groove 222 is larger than the diameter of the locking rod 31, so that the locking rod 31 does not need to move along the axis parallel to the guide groove 222 during the movement, so that the driving disk 321 can drive the locking rod 31 to move normally.

[0037] Because the diameter of the guide groove 222 is larger than the diameter of the locking rod 31, the locking rod 31 may wobble along the axis of the drive disc 321 during movement. Therefore, a limiting member 22 is provided on the guide block 21 to limit the position of the locking rod 31. In this embodiment, the limiting member 22 adopts a bolt and nut mating structure. The nut of the limiting member 22 is welded and fixed to the end face of the guide block 21 away from the cover 2. The bolt of the limiting member 22 passes through the guide groove 222 and is threadedly engaged with the nut. A guide groove 311 parallel to the locking rod 31 is provided on the side wall of the locking rod 31 away from the cover 2. The width of the guide groove 311 is larger than the diameter of the bolt of the limiting member 22. The bolt of the limiting member 22 can abut against the guide groove 311 to limit the movement direction of the locking rod 31 in the guide groove 222. After the cover 2 is placed in the hatch, the locking rod 31 can be normally inserted into the locking groove 11.

[0038] like Figure 1As shown, the second locking member 33 includes a rotating disk 331 rotatably connected to the cover 2 and a handle 332 that drives the rotating disk 331 to rotate. The end face of the cover 2 near the deck is recessed towards the hatch to form a rotating groove 23. The rotating disk 331 is embedded in the rotating groove 23 and rotates. The rotating disk 331 is connected to the drive disk 321 via a rotating shaft, allowing the rotating disk 331 and the drive disk 321 to rotate synchronously. The thickness of the rotating disk 331 is less than the depth of the rotating groove 23, so that after the rotating disk 331 is embedded in the rotating groove 23, the end face of the rotating disk 331 is flush with the end face of the cover 2 near the deck. A receiving groove 3311 is also provided on the rotating disk 331. One end of the handle 332 is rotatably connected to the receiving groove 3311. The shape of the receiving groove 3311 is the same as the shape of the handle 332, allowing the handle 332 to rotate and be fully submerged in the receiving groove 3311. The rotation axis of the handle 332 and the receiving groove 3311 intersects the extension line of the rotation axis of the rotating disk 331 itself, so that when the handle 332 is rotated upward and force is applied to the handle 332, the rotating disk 331 can be driven to rotate more effectively by the handle 332.

[0039] Two lifting grooves 24 are also provided on the end face of the cover 2 where the second driving member is provided. The two lifting grooves 24 are respectively provided on both sides of the rotating groove 23. Each lifting groove 24 is equipped with a horizontally arranged lifting member 25. The two lifting members 25 are arranged in parallel and the end face of the lifting member 25 away from the cover 2 is flush with the end face of the cover 2 near the deck.

[0040] During the ship's operation, water may accumulate on the deck. When the water flows to the hatch, it will flow directly into the hatch and affect the cabin. Therefore, a water-blocking groove 12 is provided on the upper surface of the flange 1 along its outline to prevent the water from flowing directly into the hatch.

[0041] like Figure 2 As shown, in order to further reduce the probability of water entering the hatch, a sealing strip 26 is provided along the outer contour of the end face of the first locking member 32 on the cover 2. In this embodiment, the sealing strip 26 is a rubber strip. The sealing strip 26 abuts against the upper end of the flange 1, thereby sealing the gap between the flange 1 and the cover plate, so that water on the deck is not easy to pass through the gap between the cover 2 and the flange 1.

[0042] The implementation principle of this embodiment is as follows: When it is necessary to open the hatch, rotate the handle 332 90 degrees away from the cover 2, and then hold the handle 332 so that the handle 332 drives the rotating disk 331 to rotate. The rotating disk 331 rotates synchronously with the drive disk 321, causing the locking rod 31 to disengage from the locking groove 11. Then hold the two lifting parts 25 to remove the cover 2 from above the protrusion 1 and open the hatch.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
