Description

Technical Field

[0001] This utility model belongs to the technical field of cutter suction dredgers, and in particular relates to a cable passage sealing structure with a detachable sheath for the driver's control room. Background Technology

[0002] Cutter suction dredgers play a crucial role in dredging operations across various waterways. The control room, as its core operating area, is filled with numerous complex cables used to transmit power, signals, and other signals to ensure the normal operation of the vessel's various equipment.

[0003] In prefabricated cutter suction dredgers, there are cable entry holes between the main buoy deck and the bottom plate of the bridge control room, through which cables must be connected. However, traditional cable sealing methods have several shortcomings. Firstly, the sealing effect is poor, allowing seawater and moisture to easily enter the bridge control room through these holes. This not only corrodes the cables, affecting their insulation performance and causing safety hazards such as short circuits and electrical leaks, but may also damage the precision equipment in the bridge control room, affecting the normal operation of the vessel. Secondly, traditional sealing structures are mostly fixed. When cables need replacement or maintenance, the disassembly and installation process is cumbersome, requiring significant manpower and time, reducing the vessel's maintenance efficiency. Moreover, fixed sealing structures are difficult to adapt to different specifications and quantities of cables, resulting in poor versatility.

[0004] Therefore, developing a modular cutter suction dredger cab cable sealing structure that can effectively seal, is easy to disassemble and maintain, and is adaptable to various cable conditions is of great practical significance. Utility Model Content

[0011] A further preferred embodiment has an arc-shaped chamfer on the outer edge of the inner diameter of the sheath connecting ring.

[0012] Further preferably, the welding between the cable sheath and the sheath connecting ring is a continuous full weld seal.

[0013] The advantages and technical effects of this utility model are as follows: By welding the deck fixing ring seat and the detachable cable sheath assembly to the main buoy deck, cable penetration through the hull is sealed, effectively preventing seawater and water vapor from entering the bridge control room and protecting the cables and internal equipment. The design of the outer edge size of the sheath connecting ring and the setting of the rubber sealing gasket enhance the sealing performance of the connection. The square structure of the sheath connecting ring and the deck fixing ring seat facilitates installation and positioning, ensuring connection stability. Bolt fasteners ensure reliable connection and facilitate disassembly and maintenance. The arc-shaped chamfer on the outer edge of the inner diameter of the sheath connecting ring prevents cable scratching and improves installation safety. The continuous full-welded seal between the cable sheath and the sheath connecting ring ensures a seamless connection, improves sealing performance and overall strength, ensures safe operation of the cable in complex environments, and reduces the risk of equipment failure and maintenance costs.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0021] Please see Figures 1 to 5 A cable penetration sealing structure with a detachable sheath for the bridge control room is disclosed, installed at the cable penetration holes of the main buoy deck 1 and the bridge control room floor 2. The structure comprises: a deck fixing ring 3 welded into the cable penetration hole of the main buoy deck 1; a cable sheath assembly detachably installed on the deck fixing ring 3, the cable sheath assembly including: a sheath connecting ring 4 connected to the deck fixing ring 3; a cable sheath 5 vertically welded to the sheath connecting ring 4, the upper end of the cable sheath 5 inserted into the cable penetration hole of the bridge control room floor 2; a sealing sheath 6 welded to the bridge control room floor 2; and a rubber sealing sleeve 7 sleeved on the outside of the cable sheath 5, the rubber sealing sleeve 7 located between the sealing sheath 6 and the cable sheath 5. This structure achieves cable penetration sealing, preventing seawater and water vapor from entering the bridge control room, ensuring the safety of cables and internal equipment. The detachable design also facilitates cable maintenance and replacement.

[0022] Preferably, the outer edge geometry of the sheath connecting ring 4 is greater than or equal to the outer edge geometry of the deck fixing ring seat 3. This design enhances the sealing performance at the connection between the sheath connecting ring 4 and the deck fixing ring seat 3, effectively preventing external impurities from entering. It also provides a better supporting foundation for subsequent sealing component installation, further improving the overall sealing effect of the cable penetration sealing structure and reducing the risk of equipment failure due to poor sealing.

[0023] Preferably, the sheath connecting ring 4 and the deck fixing ring seat 3 are square in shape. The square structure provides better positioning during installation, facilitating accurate installation by operators and reducing installation errors. Simultaneously, the square structure distributes stress more evenly when subjected to bolt tightening force, better ensuring connection stability and thus improving the reliability of the sealing structure, ensuring long-term stable cable penetration sealing.

[0024] A further preferred embodiment includes multiple bolts 8, which pass through the sheath connecting ring 4 from the inside of the main buoy box towards the bridge control room and connect to the deck fixing ring seat 3, without protruding from the upper end face of the deck fixing ring seat 3. The bolts 8 ensure a reliable connection between the sheath connecting ring 4 and the deck fixing ring seat 3, and facilitate disassembly. This connection method allows for adjustment of the tightening force according to actual needs, ensuring a tight connection, while also facilitating the disassembly and maintenance of the cable sheath assembly when necessary, thus improving maintenance efficiency.

[0025] Preferably, a rubber sealing gasket 9 is provided between the sheath connecting ring 4 and the deck fixing ring seat 3. This effectively fills the tiny gap between the sheath connecting ring 4 and the deck fixing ring seat 3, enhancing the sealing effect. It prevents seawater, water vapor, etc., from entering the control room through the connection, further protecting cables and internal equipment, extending equipment lifespan, and reducing maintenance costs caused by sealing problems.

[0026] Preferably, the outer edge of the inner diameter of the sheath connecting ring 4 is provided with an arc-shaped chamfer. This arc-shaped chamfer design prevents the cable from scratching against the outer edge of the inner diameter of the sheath connecting ring 4 during installation or use, reducing damage to the cable insulation layer and improving cable safety. Simultaneously, this design also facilitates smooth cable insertion, reduces installation difficulty, improves installation efficiency, and makes the entire cable insertion sealing structure installation process more convenient.

[0027] Preferably, the welding of the cable sheath 5 and the sheath connecting ring 4 is a continuous full weld seal. A continuous full weld seal ensures that there are no gaps at the connection between the cable sheath 5 and the sheath connecting ring 4, effectively preventing the ingress of seawater, water vapor, etc., and greatly improving the sealing performance of the sealing structure. This welding method also enhances the overall strength of the cable sheath 5 and the sheath connecting ring 4, making the cable sheath assembly more stable and ensuring the safe operation of the cable in complex environments.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
