Description

Technical Field

[0001] This utility model relates to the technical field of hatch cover devices, specifically a hatch cover structure that is easy to observe and disassemble. Background Technology

[0002] Hatch covers are critical protective components for ship cabins, playing a vital role in weatherproofing and preventing water ingress. They directly impact ship navigation safety and the protection of cargo and equipment within the cabins. Existing ship hatch covers suffer from two major shortcomings in practical use:

[0003] In terms of opening and locking, traditional structures often use multi-point independent locking devices or pin-type designs, requiring each locking point to be unlocked one by one, which is cumbersome and inefficient. In terms of observation function, traditional hatch covers lack dedicated observation structures, requiring personnel to frequently open the hatch to check the condition inside the cabin, which increases operating costs and damages the integrity of the cabin's seal, posing a safety hazard, especially in harsh sea conditions. Utility Model Content

[0004] (I) Technical Issues

[0005] This utility model provides a ship hatch cover structure that combines quick unlocking and disassembly with real-time observation capabilities, solving the problems of inconvenient opening and lack of effective observation methods in traditional hatch covers.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a hatch cover structure that is easy to observe and disassemble, applied to a ship hatch, including a hatch cover body, one end of which is hinged to the side of the ship hatch. The inner side of the hatch cover body is provided with a receiving cavity. Multiple locking rods are slidably provided on the top surface of the receiving cavity along its circumference. A synchronous drive disk is provided on the bottom surface of the receiving cavity via a ring track. Each locking rod on the synchronous drive disk has an arc-shaped through groove extending from the edge inward. A cylindrical pin is fixed at the bottom of the locking rod and engages with the arc-shaped through groove. The hatch cover body is provided with a drive assembly for driving the synchronous drive disk to rotate. The center of the hatch cover body is provided with an observation port that penetrates the receiving cavity. Multiple layers of tempered glass are fixed inside the observation port.

[0008] Furthermore, four linear guide rails arranged in a cross shape are fixedly provided on the top surface inside the cavity, and sliders are slidably mounted on the linear guide rails, with locking rods fixedly mounted at the bottom of the sliders.

[0009] Furthermore, the sidewall of the receiving cavity is provided with a through hole for each locking rod to extend out, and the upper edge of the inner side of the ship hatch is fixedly provided with a boss for engaging with the locking rod.

[0010] Furthermore, the drive assembly includes a gear ring disposed at the edge of the synchronous drive disk, and a gear rotatably disposed inside the receiving cavity. The gear meshes with the gear ring, and a rotating wheel is fixedly disposed at one end of the gear's central axis extending above the receiving cavity.

[0011] Furthermore, a locking bolt is inserted into the rotating wheel, and the upper end face of the hatch cover body is provided with a threaded hole that matches the locking bolt. When the locking rod is locked, the locking bolt and the threaded hole are in the same position.

[0012] Furthermore, the hinge point between the hatch cover body and the side of the ship's hatch adopts a vertical elongated hole.

[0013] Furthermore, a ramp is provided on the upper side of the outer end of the locking rod.

[0014] (III) Technical Effects

[0015] The advantages of this utility model compared with the prior art are:

[0016] 1. By cooperating with the synchronous drive disc and the arc-shaped through groove, the rotation of the wheel can realize the synchronous extension and retraction of multiple locking rods without the need for individual operation, which greatly improves the opening and closing efficiency; the hinged design of the vertical elongated hole and the inclined structure of the outer end of the locking rod reduce the risk of jamming.

[0017] 2. The multi-layered tempered glass observation port in the center of the hatch allows for real-time monitoring of the cabin conditions without opening the hatch, saving operating costs and maintaining the integrity of the cabin's seal. The linear guide rail ensures precise sliding of the locking rod, and the locking bolts and threaded holes enhance the stability of the locking rod in the locked state, preventing the synchronous drive disc from rotating on its own due to vibration.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Combined with appendix Figure 1 To be continued Figure 7A hatch cover structure that is easy to observe and disassemble is applied to a ship hatch 2. It includes a hatch cover body 1, one end of which is hinged to the side of the ship hatch 2. The inner side of the hatch cover body 1 is provided with a receiving cavity 3. Multiple locking rods 4 are slidably provided on the top surface of the receiving cavity 3 along its circumference. The bottom surface of the receiving cavity 3 is provided with a synchronous drive disk 6 that rotates through a ring track 5. Each locking rod 4 on the synchronous drive disk 6 has an arc-shaped through groove 7 extending from the edge to the inward side. The bottom of the locking rod 4 is fixed with a cylindrical pin 8 that engages with the arc-shaped through groove 7. The hatch cover body 1 is provided with a drive assembly for driving the synchronous drive disk to rotate. The center of the hatch cover body 1 is provided with an observation port 9 that penetrates the receiving cavity 3. Multiple layers of tempered glass 10 are fixed inside the observation port 9. The hinge point between the hatch cover body 1 and the side of the ship hatch 2 is provided with a vertical elongated hole 19. The upper side of the outer end of the locking rod 4 is provided with a ramp 20.

[0030] In this embodiment, as a preferred technical solution, four linear guide rails 11 arranged in a cross shape are fixedly provided on the top surface inside the receiving cavity 3. A slider 12 is slidably provided on the linear guide rails 11. A locking rod 4 is fixedly provided at the bottom of the slider 12. The side wall of the receiving cavity 3 is provided with a through hole 13 for each locking rod 4 to extend out. A boss 14 for engaging with the locking rod 4 is fixedly provided on the upper edge of the inner side of the ship hatch 2.

[0031] In this embodiment, as a preferred technical solution, the driving component includes a gear ring 15 located at the edge of the synchronous driving disk 6, and a gear 16 rotatably located inside the receiving cavity 3. The gear 16 meshes with the gear ring 15, and a rotating wheel 17 is fixedly provided at one end of the gear 16 extending above the receiving cavity 3. A locking bolt 18 is inserted into the rotating wheel 17, and a threaded hole adapted to the locking bolt 18 is provided on the upper end face of the hatch cover body 1. When the locking rod 4 is locked, the locking bolt 18 corresponds to the position of the threaded hole.

[0032] The working principle of this utility model is as follows: This utility model uses a synchronous drive disc 6 as the transmission core, and utilizes the meshing relationship between its edge gear ring 15 and gear 16 to convert the rotational motion of the rotating wheel 17 into the rotation of the synchronous drive disc 6; the arc-shaped through groove 7 on the synchronous drive disc 6 forms a sliding fit with the cylindrical pin 8 at the bottom of the locking rod 4. When the disc rotates, the guiding effect of the arc-shaped through groove 7 drives the locking rod 4 to make synchronous telescopic motion along the linear guide rail 11, realizing the rapid locking or unlocking of the hatch cover body 1 and the ship hatch 2; the hinged design of the vertical elongated hole 19 provides flexible space for opening the hatch cover, and the ramp 20 structure at the outer end of the locking rod 4 can relieve the alignment pressure during locking and reduce jamming; the observation port 9 of the multi-layer tempered glass 10 in the center of the hatch cover body 1 allows direct observation of the inside of the hatch without breaking the seal, and the engagement of the locking bolt 18 with the threaded hole can fix the position of the synchronous drive disc 6, prevent vibration from causing self-unlocking, and ensure locking stability.

[0033] The working process of this utility model is as follows:

[0034] Unlocking steps: The operator first unscrews the locking bolt 18 to disengage it from the threaded hole on the upper end face of the hatch cover body 1, thus releasing the fixation restriction on the synchronous drive disc 6; then rotate the rotating wheel 17, which drives the gear 16 to rotate, and the gear 16 drives the synchronous drive disc 6 to rotate synchronously along the annular track 5 through the gear ring 15; when the synchronous drive disc 6 rotates, the arc-shaped through groove 7 pulls each locking rod 4 through the cylindrical pin 8, causing the locking rod 4 to retract synchronously into the receiving cavity 3 along the linear guide rail 11 until the outer end of the locking rod 4 completely disengages from the boss 14 on the inner side of the ship's hatch 2, and the unlocking is completed.

[0035] Opening steps: After unlocking, the operator can directly lift the hatch cover body 1 upwards. Since the hinge between the hatch cover body 1 and the ship hatch 2 adopts the design of vertical elongated hole 19, it can adapt to the angle adjustment and displacement compensation during the opening process, and avoid the hinge point jamming.

[0036] Observation steps: With the hatch closed and locked, the operator does not need to open the hatch. They can directly observe the cargo, equipment and environmental conditions inside the hatch in real time through the tempered glass 10 inside the central observation port 9 of the hatch cover body 1. This achieves contactless monitoring, which saves the operating costs of frequent opening and closing, and maintains the sealing integrity of the ship's hatch 2.

[0037] Closing and Locking Procedure: When closing, lower the hatch cover body 1 to the ship's hatch 2 to ensure a tight seal; rotate the wheel 17 in the opposite direction, which drives the synchronous drive disc 6 to rotate in the opposite direction through the transmission of the gear 16 and the gear ring 15. The arc-shaped through groove 7 pushes each locking rod 4 to extend outward synchronously along the linear guide rail 11 through the cylindrical pin 8. The ramp 20 at the outer end of the locking rod 4 can help it smoothly engage with the inner side of the boss 14, completing the initial locking; finally, insert the locking bolt 18 into the wheel 17 and screw it into the corresponding threaded hole to fix the position of the synchronous drive disc 6, preventing it from rotating on its own due to vibrations during ship navigation, further enhancing the locking stability. The entire process does not require operating the locking rods one by one, making it efficient and convenient.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
