Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, in particular to a water blocking device for an elastic joint of a superstructure of a ship. BACKGROUND

[0002] In order to improve the maneuverability and loading performance of the ship, more and more ships are designed quantitatively, and the superstructure of the ship is usually made of thin steel plates to reduce the weight of the ship. In order to reduce the degree of participation of the superstructure in the overall longitudinal bending deformation of the ship body, an elastic joint is needed to divide the superstructure into several short superstructures that can move relatively. However, due to the special structure of the elastic joint, the end portions on both sides of the elastic joint cannot be completely welded with the ship body, and there will always be a gap of several millimeters to several tens of millimeters. Water on the open deck will seep into the lower deck through these gaps, accelerating the corrosion or damage of the ship body components and equipment on the lower deck, and also increasing the workload of daily maintenance of the ship.

[0003] In order to prevent water from flowing into the lower deck along the gap at the end of the elastic joint, the elastic joint is usually lengthened and bent to the next deck. For example, a kind of elastic joint and connecting method for ship superstructure is disclosed in Chinese patent CN202110685153.4, which extends the elastic connecting piece to the side wall of the superstructure, and drains rainwater and the like to the lower side of the side wall for discharge. However, this not only significantly increases the weight of the elastic joint, which is not conducive to the control of the weight of the ship, but also makes the processing and manufacturing of the bending transition structure of the elastic joint very difficult, and the processing cycle is long, which is not conducive to the control of the shipbuilding cycle and cost.

[0029] To better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figures 1-4 As described above, this embodiment provides a water-blocking device for a flexible joint used in ship superstructures, such as... Figure 2 As shown, the flexible joint 4 has a U-shaped plate structure. The top two sides of the flexible joint 4 are connected to the upper deck 5 respectively. The water-blocking device includes a water guide plate 2, a support seat 1 and fasteners. The upper end of the water guide plate 2 is provided with a groove that matches the flexible joint 4. The end of the flexible joint 4 near the outer plate 8 is locked in the groove of the water guide plate 2. The lower end of the water guide plate 2 faces the lower deck 6. Support seats 1 are provided on both the left and right sides of the water guide plate 2. The support seats 1 are set along the outer plate 8. One end of the support seat 1 is fixed on the outer plate 8. The other end of the support seat 1 is detachably connected to the water guide plate 2 by fasteners.

[0032] like Figure 1As shown, in this embodiment, the support base 1 is an L-shaped steel plate. The web end of the support base 1 is welded to the outer plate of the hull. Multiple bolt holes are provided on the panel of the support base 1 from top to bottom. Multiple bolt holes are provided on both sides of the water guide plate 2 from top to bottom. The fasteners include bolts and nuts. The bolts pass through the bolt holes of the support base 1 and the water guide plate 2 to fix the water guide plate 2 to the outer plate of the hull.

[0033] To increase the stability of the connection between the support base 1 and the water guide plate 2, a pressure strip 3 is also fitted on the bolt. The pressure strip has multiple bolt holes. After the support base 1 and the water guide plate 2 are connected, the bolt is provided with a nut, the panel of the support base 1, the water guide plate 2, the pressure strip 3 and the nut in sequence from the inside to the outside. The pressure strip 3 is an aluminum alloy strip with an anti-slip surface. The anti-slip surface of the pressure strip 3 is corrugated and is in close contact with the water guide plate 2.

[0034] In this embodiment, the water guide plate 2 is made of elastic rubber, which not only increases the corrosion resistance of the water guide plate 2 but also reduces the weight of the water-blocking device. The water guide plate 2 has a distance from both the upper deck 5 and the lower deck 6. The distance between the upper end of the water guide plate 2 and the upper deck 5 is 40-60mm, preferably 50mm, and the distance between the lower end of the water guide plate 2 and the lower deck 6 is 80-120mm, preferably 100mm. Support seats 2 are symmetrically arranged on both sides of the water guide plate 2, with a distance between the support seats of 400-600mm, preferably 500mm. The web length of the support seat 1 is 100mm, the web thickness of the support seat 1 is 5mm, the length of the panel of the support seat 1 is 70mm, and the width of the pressure strip 3 is 60mm.

[0035] Example 2

[0036] The water-blocking device for the flexible joint of the ship's superstructure in this embodiment is basically the same as that in Embodiment 1, except that, as follows: Figure 5 As shown, the support seats 2 on both sides of the water guide plate 2 are asymmetrically arranged, and at least one support seat 2 is installed in a zigzag shape. The shape of the vertical sides of the water guide plate 2 corresponds to the orientation shape of the support seat 2, and the shape of the pressure strip corresponds to the orientation shape of the support seat 2. By installing the support seats in a zigzag shape, the water-blocking device of the flexible joint for the superstructure of the ship can be avoided from the installation of equipment or pipelines.

[0037] Example 3

[0038] The water-blocking device for the flexible joint of the ship's superstructure in this embodiment is basically the same as that in Embodiment 1, except that, as follows: Figure 6 As shown, the width of the guide plate 2 is greater than the distance between the support bases 1. When the guide plate 2 is fixed to the support base 1, the guide plate 2 is curved. By setting the guide plate 2 in a curved shape, the guide plate 2 can have a larger elongation compensation amount, so as to adapt to the situation where the relative displacement of the fore and aft outer plates of the ship's elastic joint is large due to the large displacement of the ship's movement displacement.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation methods of the application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all of them should be covered within the scope of the technical solutions claimed in this application.
