Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to a watertight cable penetration component for ships. Background Technology

[0002] Currently, when cables pass through watertight walls on ships under construction, in order to ensure that the cable passage location meets the watertight requirements, cable penetration parts are welded onto the bulkhead where the cable passes through the compartment. The cable passes through the cable penetration parts, and then the two ends of the cable penetration parts are sealed with filler material. Filler grout is poured into the cable penetration parts through the pouring holes on the cable penetration parts, so that the grout fills the gap between the cable and the cable. After the grout dries, the grout and the cable become a whole, achieving the watertight requirement for the cable to pass through the bulkhead.

[0003] The current conventional grouting operation for cable penetrations involves welding the cable penetration to the wall panel, passing the cable through it, and then sealing both ends of the penetration with sealing material to prevent grout from flowing out during grouting. Workers then place a funnel over the pouring hole of the cable penetration and inject the grout into the cable penetration through the funnel. However, using conventional cable penetrations presents the following problems: 1. Some spaces on board are confined, making it inconvenient for workers to operate; 2. Most cable penetrations are installed on the top of the cabin, requiring workers to work at height; 3. During grouting, grout can easily leak from the funnel, polluting the surrounding environment and cables, requiring secondary manual cleaning and wasting grouting materials; 4. Low construction efficiency, long construction period, and high work intensity and difficulty for workers. Utility Model Content

[0004] The purpose of this utility model is to provide a watertight cable penetration component for ships, which ensures the tightness of the grouting point, prevents grouting material from overflowing, saves grouting material, is not limited by the environment, and reduces the difficulty and intensity of grouting construction for workers.

[0005] To achieve the above objectives, this utility model provides a watertight cable penetration component for ships, including a penetration pipe, a casting connection port, a venting connection port, a casting pipe, and a venting pipe. The casting connection port and the venting connection port are respectively connected to the penetration pipe and communicate with the inner cavity of the penetration pipe. The casting connection port is threaded to the casting pipe, and the venting connection port is threaded to the venting pipe.

[0006] As a preferred embodiment of this utility model, a delivery pump is connected to the pouring pipe.

[0007] As a preferred embodiment of this utility model, the outlet of the casting pipe is connected to the casting connection pipe opening, the inlet of the casting pipe is connected to the liquid outlet of the delivery pump, the liquid inlet of the delivery pump extends into the bottom of the grouting liquid container, and the outlet of the vent pipe extends into the grouting liquid container.

[0008] As a preferred embodiment of this utility model, both the casting connection port and the venting connection port are provided with internal threads, the casting pipe is provided with external threads that are threadedly connected to the internal threads of the casting connection port, and the venting pipe is provided with external threads that are threadedly connected to the internal threads of the venting connection port.

[0010] As a preferred embodiment of this utility model, the casting pipe is a flexible tube.

[0011] As a preferred embodiment of this utility model, the cross-section of the through pipe is circular.

[0012] Compared with the prior art, the beneficial effects of this utility model embodiment of a watertight cable penetration component for ships are as follows:

[0013] This invention uses a threaded connection between the pouring pipe and the pouring connection pipe to ensure that the pouring pipe will not detach from the pouring connection pipe on the through pipe during the pouring process, avoiding detachment due to stress. It also ensures the tightness between the pouring pipe and the pouring connection pipe, preventing grout material from overflowing, saving grout material, and is not limited by the environment, reducing the difficulty and intensity of grouting construction for workers. The threaded connection between the venting connection pipe and the venting pipe facilitates the discharge of air from the through pipe during grouting, and provides a good sealing effect.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figs. 1-2 As shown, a preferred embodiment of the present invention provides a marine watertight cable penetration component, comprising a penetration pipe 1, a casting connection port 2, a venting connection port 3, a casting pipe 4, and a venting pipe 5. The casting connection port 2 and the venting connection port 3 are respectively connected to the penetration pipe 1 and communicate with the inner cavity of the penetration pipe 1. The casting connection port 2 is threadedly connected to the casting pipe 4, and the venting connection port 3 is threadedly connected to the venting pipe 5.

[0021] This invention ensures that the pouring pipe 4 will not fall off the pouring connection pipe 2 during the pouring process by threading the pouring pipe 4 to the pouring connection pipe 2 on the through pipe 1, thus avoiding detachment due to stress. It also ensures the tightness between the pouring pipe 4 and the pouring connection pipe 2, preventing the grouting material from overflowing, saving grouting material, and reducing the difficulty and intensity of grouting construction for workers, as it is not limited by the environment. The venting connection pipe 3 is threadedly connected to the venting pipe 5, which facilitates the discharge of air from the through pipe 1 during grouting and provides a good sealing effect.

[0022] For example, the pouring pipe 4 is connected to a delivery pump 6, which greatly improves the grouting efficiency.

[0023] Furthermore, the outlet of the pouring pipe 4 is connected to the pouring connection pipe 2, the inlet of the pouring pipe 4 is connected to the outlet of the delivery pump 6, the inlet of the delivery pump 6 extends into the bottom of the grout container 7, and the outlet of the vent pipe 5 extends into the grout container 7. When the inside of the through pipe 1 is filled with grout, cable grout will be discharged from the vent pipe 5, which facilitates the direct return of the cable grout to the grout container 7 and avoids waste of grouting materials.

[0024] In this embodiment, both the casting connection port 2 and the venting connection port 3 are provided with internal threads. The casting pipe 4 is provided with external threads that are threadedly connected to the internal threads of the casting connection port 2. The venting pipe 5 is provided with external threads that are threadedly connected to the internal threads of the venting connection port 3, so as to ensure a good sealing effect during grouting.

[0025] For example, both the pouring connection port 2 and the venting connection port 3 are located on the upper side of the through pipe 1 to facilitate the air discharge from the through pipe 1 and ensure that the grouting material fills the interior of the through pipe 1.

[0026] For example, the casting pipe 4 is a flexible hose, which makes it convenient for the casting pipe 4 to be routed around the narrow space on the ship.

[0027] Furthermore, the cross-section of the through pipe 1 is circular, which facilitates the welding connection between the through pipe 1 and the cabin wall panel 8.
