Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically a dual-mode hull sealing hatch cover. Background Technology

[0002] Various hatches, passageways, and equipment entrances on a ship's hull require sealed hatch covers to ensure the ship's watertightness, airtightness, and internal environmental safety. Traditional hull sealed hatch covers typically employ a single opening and closing mode, such as a simple hinged hinged hatch or a bolt-locked cover. These types of hatches have functional limitations: hinged hatches occupy external space when opened, potentially causing obstruction when deck equipment is densely packed or space is limited, and their sealing rating is usually difficult to significantly improve when needed; while bolt-locked cover types, although achieving high-pressure sealing, are cumbersome and time-consuming to open and close, making them unsuitable for scenarios requiring frequent access or rapid opening, especially on some special vessels, offshore platforms, or in situations requiring both convenient daily passage and high-level sealing under specific operating conditions. A single sealing and opening mode cannot meet diverse usage needs. For example, during normal navigation or berthing, a hatch with basic weather protection may be necessary; however, in harsh sea conditions, underwater operations, or special missions, the hatch needs to be able to quickly transform into a safety barrier with high pressure resistance and a high sealing rating. Therefore, there is an urgent need for a hatch structure that can flexibly switch between different sealing and opening modes according to actual needs. Utility Model Content

[0014] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0015] Figure 1-4 In one embodiment of this utility model, a mounting ring 1 is included. Handles are fixedly mounted on both sides of the surface of the mounting ring 1. The surface of the handles is adhered with a soft pad to improve comfort. The surface of the mounting ring 1 is provided with a plurality of mounting grooves at equal intervals in a ring shape. Positioning bolts 2 are provided inside the mounting grooves. A sealing ring 3 is fixedly mounted on the bottom of the mounting ring 1. A sealing component 4 is provided on one side of the surface of the sealing ring 3. A retaining ring 5 is provided inside the mounting ring 1. A limiting plate 6 is fixedly mounted on one side of the surface of the mounting ring 1. An adjusting component 7 is provided on the surface of the limiting plate 6. A sealing cover 8 is provided at one end of the adjusting component 7. An embedding groove is provided inside the sealing cover 8. A sealing gasket to improve sealing performance is embedded inside the embedding groove. The adjustment assembly 7 includes an electric push rod 71 fixedly installed on one side of the surface of the limiting plate 6. An installation block 72 is fixedly installed at the output end of the electric push rod 71. A guide rod 73 is rotatably connected to the surface of the installation block 72. A support rod 74 is fixedly installed on one side of the surface of the limiting plate 6. A positioning block 75 is rotatably connected to the top of the support rod 74. A through groove is opened on the surface of the positioning block 75. The size of the through groove is adapted to the size of the guide rod 73. The bottom of the positioning block 75 is fixedly installed in the middle of the surface of the sealing cover 8. The positioning block 75 drives the sealing cover 8 to rotate.

[0016] When the sealing cover 8 is opened, the operator starts the electric push rod 71. Its output end will drive the mounting block 72 to move downward. When the mounting block 72 moves downward, it will drive the guide rod 73 to present different angles. When the guide rod 73 is adjusted in angle, it will drive the positioning block 75 to rotate. The support rod 74 supports the positioning block 75. The guide rod 73 drives the sealing cover 8 to adjust to different angles.

[0017] The sealing assembly 4 includes a servo motor 41 fixedly installed on one side of the surface of the mounting ring 1. A connecting block 42 is fixedly installed at the output end of the servo motor 41. A limit block 43 is snapped onto the surface of the connecting block 42. A sealing plate 44 is fixedly installed at the bottom of the limit block 43. The size of the sealing plate 44 is adapted to the size of the inside of the sealing ring 3. The sealing plate 44 seals the sealing ring 3.

[0018] When sealing the sealing ring 3, the operator connects the servo motor 41 to the power supply. Its output end will drive the connecting block 42 to rotate. When the connecting block 42 rotates, it will drive the limiting block 43 to rotate. The limiting block 43 will drive the sealing plate 44 to rotate. When the sealing plate 44 rotates to directly above the sealing ring 3, the sealing plate 44 will seal the sealing ring 3.

[0019] In this embodiment, during normal operation, when personnel need to pass through, the electric push rod 71 retracts, and the sealing cover 8 quickly flips open. After passage, the electric push rod 71 extends, and the sealing cover 8 closes and locks. When the ship enters conditions requiring a high level of sealing, such as diving, storm resistance, or maintaining cabin pressure, the sealing cover 8 is ensured to be in the open state or a position that does not affect the rotation of the sealing plate 44. Then, the servo motor 41 is controlled to drive the sealing plate 44 to rotate into the channel of the sealing ring 3 and lock it, thus sealing the core channel. At this time, the sealing cover 8 can be closed as needed for additional protection. The two modes are independent of each other and can be flexibly switched according to instructions to meet complex and ever-changing maritime needs.
