Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a waterproof device for ship escape hatches. Background Technology

[0002] In the modern shipbuilding industry, precision shipbuilding and rapid shipbuilding have become important trends, significantly improving the economic efficiency, reducing costs, and enhancing market competitiveness of shipbuilding enterprises. During the shipbuilding process, the assembly and loading phases of bulk carriers require operations on open decks. The top deck surfaces of these two phases typically have manhole structures of various specifications. While some manholes are equipped with standard manhole covers as required, manholes with special functions (such as escape hatches) often lack standard covers.

[0003] However, during the rainy season, unsealed escape hatches allow rainwater to seep directly into the cabins, causing water accumulation. This not only affects the shipbuilding schedule but also reduces construction quality and increases the cost and workload of subsequent water removal. Traditional solutions mainly rely on temporary sealing measures, such as manually laying waterproof tarpaulins or simple covers. However, temporary sealing measures cannot guarantee a reliable seal, and vibrations during ship navigation can easily cause waterproofing failure. Secondly, the installation of temporary measures is time-consuming and labor-intensive in practice, failing to meet the requirements of rapid transfer and efficient construction in modern shipbuilding. These problems directly lead to a significant investment of manpower and resources in cleaning up water accumulation in the cabins, severely impacting construction efficiency and economy.

[0036] In the modern shipbuilding industry, precision shipbuilding and rapid shipbuilding have become important trends, significantly improving the economic efficiency, reducing costs, and enhancing market competitiveness of shipbuilding enterprises. During the shipbuilding process, the assembly and loading phases of bulk carriers require operations on open decks. The top deck surfaces of these two phases typically have manhole structures of various specifications. While some manholes are equipped with standard manhole covers as required, manholes with special functions (such as escape hatches) often lack standard covers.

[0037] However, during the rainy season, unsealed escape hatches allow rainwater to seep directly into the cabins, causing water accumulation. This not only affects the shipbuilding schedule but also reduces construction quality and increases the cost and workload of subsequent water removal. Traditional solutions mainly rely on temporary sealing measures, such as manually laying waterproof tarpaulins or simple covers. However, temporary sealing measures cannot guarantee a reliable seal, and vibrations during ship navigation can easily cause waterproofing failure. Secondly, the installation of temporary measures is time-consuming and labor-intensive in practice, failing to meet the requirements of rapid transfer and efficient construction in modern shipbuilding. These problems directly lead to a significant investment of manpower and resources in cleaning up water accumulation in the cabins, severely impacting construction efficiency and economy.

[0038] Therefore, such as Figures 1 to 3 As shown, the waterproof device for the ship's escape hole proposed in this utility model includes a square ring tube 200, a square cover plate 300, a waterproof strip 210, and a connecting assembly 400. The square ring tube 200 is arranged around the escape hole 101 of the deck 100. The square cover plate 300 is rotatably installed on the square ring tube 200 and can cover the square ring tube 200. The waterproof strip 210 is fixedly connected to the lower surface of the square ring tube 200 and arranged around the escape hole 101. Furthermore, the connecting assembly 400 includes a rotating shaft 410, a locking washer 420, and a fixing bolt 430. The rotating shaft 410 is fixedly connected to the inner side of the square ring tube 200. One end of the locking washer 420 is sleeved on the rotating shaft 410. The fixing bolt 430 is threadedly connected to the other end of the locking washer 420. The fixing bolt 430 can be screwed through the locking washer 420 to push against the lower surface of the deck 100 and drive the waterproof strip 210 to adhere tightly to the upper surface of the deck 100. It should be noted that the arrangement of square ring tubes 200 around the escape hole 101, along with the waterproof strips 210 fixedly connected to the lower surface of the square ring tubes 200, can form a tight seal with the upper surface of the deck 100, effectively preventing rainwater from seeping into the compartment. Specifically, by tightening the threads, the fixing bolts 430 push against the lower surface of the deck 100, thereby driving the waterproof strips 210 to compact and adhere to the deck 100, significantly improving the reliability of the seal. This not only ensures the device's ability to resist vibration during ship navigation but also enables rapid installation and disassembly, greatly improving construction efficiency and reducing maintenance costs. It is particularly suitable for rapid deployment and use at the shipbuilding site.

[0039] Specifically, in some embodiments of this utility model, such as Figure 1As shown, the rotating shaft 410 includes a fixing part 411 and a threaded part 412. The fixing part 411 is fixedly connected to the square ring tube 200, and the locking washer 420 is rotatably sleeved on the threaded part 412 and threadedly connected to the threaded part 412, realizing precise adjustment of the locking function. It should be noted that the solid connection between the fixing part 411 and the square ring tube 200 provides reliable support for the locking washer 420, while the threaded part 412 allows for precise angle adjustment of the locking washer 420, enabling the device to adapt to the surface of the deck 100 of different thicknesses, thereby ensuring a tight fit between the waterproof strip 210 and the deck 100, thus improving the adaptability and reliability of the sealing effect. The threaded adjustment method is easy to operate and further improves construction efficiency. Optionally, the fixing part 411 is welded to the square ring tube 200, further enhancing the overall strength and stability of the structure. It is understood that the welding connection eliminates the loosening problem that may occur with bolted connections, ensuring the positional accuracy and reliability of the rotating shaft 410 in long-term use. In addition, this design improves the device's ability to resist ship vibrations and environmental loads, extends its service life, simplifies maintenance requirements, and reduces long-term operating costs.

[0040] Furthermore, in some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a drainage groove 202 is provided on the upper surface of the square ring pipe 200. The two ends of the drainage groove 202 are open structures 2021. For example, the open structure 2021 is a drainage outlet provided at both ends of the drainage groove 202 to allow water to flow out. In this way, rainwater can be quickly guided out, effectively preventing water from accumulating on the surface of the device, and structural corrosion caused by water accumulation can be avoided, which significantly improves the durability and reliability of the device.

[0041] Refer to Figures 1 to 3In some embodiments of this utility model, multiple square tube reinforcing tubes 310 are fixedly arranged on the side of the cover plate facing the square ring tube 200. These reinforcing tubes 310 are respectively arranged around the perimeter and diagonally of the cover plate, significantly improving the overall strength and deformation resistance of the square cover plate 300 structure. It is understood that these square tube reinforcing tubes 310, distributed around the perimeter and diagonally of the square cover plate 300, form an effective support network capable of withstanding mechanical stress, vibration impact, and loads from personnel or equipment passing through during ship operations. This structural design not only extends the service life of the cover plate but also ensures its stability during long-term use, preventing deformation or damage caused by frequent opening and closing or external forces, thereby ensuring the reliability and safety of the waterproof device. Furthermore, a hinge structure 320 is provided at the connection between the square cover plate 300 and the square ring tube 200, enabling the square cover plate 300 to rotate and open and close flexibly and reliably. For example, the hinge structure 320 is provided on a hinge, and the square cover plate 300 and the square ring tube 200 are connected via a hinge. Furthermore, a connecting rod support structure 330 is connected between the square cover plate 300 and the square ring tube 200 to drive the square cover plate 300 to remain at a preset angle after opening. This further optimizes the opening and closing performance of the cover plate, which facilitates the passage of personnel or equipment, prevents the risk of the square cover plate 300 closing accidentally, improves the safety and convenience of operation, reduces the need for manual intervention, and improves construction efficiency.

[0042] Optionally, in some embodiments of this invention, the waterproof adhesive strip 210 is adhered and fixed to the square ring tube 200, achieving a firm connection of the sealing components. It is understood that the adhesion and fixing process simplifies the installation process, improves production efficiency, and reduces maintenance costs. The tight fit of the waterproof adhesive strip 210 effectively blocks rainwater penetration, significantly improving the waterproof effect of the device.

[0043] In addition, refer to Figure 1 In some embodiments of this utility model, the square ring tube 200 is symmetrically provided with multiple lifting lugs 201 to lift the square ring tube 200, greatly improving the convenience of hoisting and transporting the device. Furthermore, the evenly distributed design of the lifting lugs 201 ensures balance and stability during hoisting, adapting to the frequent position adjustment needs during the segmented construction of ships. This design allows the device to be quickly deployed to escape holes 101 in different locations, improving construction flexibility and efficiency.

[0044] Refer to Figure 2In some embodiments of this utility model, there are multiple connecting components 400, which are arranged at intervals around the circumference of the square ring tube 200. The synergistic effect of the multiple connecting components 400 ensures a tight fit between the square ring tube 200 and the deck 100, avoids sealing failure caused by local stress concentration, improves the waterproof performance and structural stability of the device, realizes uniform force and stable locking of the waterproof device, and can adapt to various working conditions in ship operations, including vibration, impact and changes in ambient temperature, significantly improving the reliability and durability of the device.

[0045] Refer to Figure 4 According to the usage method of this utility model embodiment, the waterproof device for ship escape hatches of this utility model embodiment is applied, wherein the usage method includes the following steps:

[0046] S100 Initialization: Rotate the locking pad 420 around the rotating shaft 410 until the gap between the locking pad 420 and the waterproof strip 210 is consistent with the thickness of the deck 100. When the locking pad 420 stops, the end of the locking pad 420 away from the rotating shaft 410 is arranged towards the center of the square ring tube 200.

[0047] S200 Installation and Fixing: After initialization, move the square ring tube 200 above the escape hole 101 and place it on the surface of the deck 100. Then, rotate the locking pad 420 around the rotating shaft 410 to drive the locking pad 420 to the bottom of the deck 100. Next, tighten the fixing bolt 430 to drive the waterproof strip 210 to stick tightly to the surface of the deck 100.

[0048] Standardized operating procedures ensured optimal device performance. Specifically, the precise adjustment of the gap between the locking washer 420 and the waterproof strip 210 during initialization ensured that the initial state of the device met design requirements, laying the foundation for reliable sealing. It should be noted that the fact that the gap between the locking washer 420 and the waterproof strip 210 is the same as the thickness of the deck 100 does not mean that the gap is exactly equal to the thickness of the deck 100. Due to limitations in the rotational adjustment of the threads of the locking washer 420 and the bolted connection 412, as well as the orientation of the locking washer 420, the gap between the locking washer 420 and the waterproof strip 210 can be understood as being close to the thickness of the deck 100. Then, during installation and fixing, the locking washer 420 is rotated back under the deck 100, and the deck 100 is tightened by screwing in the fixing bolts 430.

[0049] Furthermore, refer to Figure 5The usage method also includes S300, opening and closing: After installation and fixing, because a connecting rod support structure 330 is provided between the square cover plate 300 and the square ring tube 200, in some applications, when it is necessary to open the square cover plate 300, one hand can be used to gently lift the square cover plate 300, lift it to more than 90° and then release it. The square cover plate 300 will stop falling to a certain angle due to the restriction of the connecting rod support structure 330, and the process of opening the square cover plate 300 is completed. In other applications, when it is necessary to close the square cover plate 300, one hand supports the square cover plate 300, and the other hand gently folds the lower connecting rod support structure 330 so that the connecting rod support structure 330 is in an "L" shape. Then, the hand supporting the square cover plate 300 is released, and the square cover plate 300 slowly falls to the top of the square ring tube 200, and the process of closing the square cover plate 300 is completed.

[0050] In summary, this device, which can be installed according to changes in the construction location of different sections and can be quickly transported, provides advantages such as shelter from wind and rain, effectively solving the problem of water accumulation. This avoids the company investing significant manpower and resources in cleaning up indoor water, playing a decisive role in improving subsequent labor efficiency and saving labor costs. Furthermore, this product is simple to manufacture, practical, and cost-effective, making it widely applicable in shipbuilding processes.
