[0001] The utility model generally relates to the technical field of ships, and particularly relates to a cable pipe assembly passing through a cabin and a ship having the same. Background Art

[0002] When the deck cables of existing ships are routed, they usually need to pass through a watertight cabin. For this reason, a threading hole for the deck cables to pass through is opened in the bulkhead of the watertight cabin. A cabin-piercing pipe is welded in the threading hole and the deck cables are arranged through the cabin-piercing pipe. In order to prevent the liquid in the watertight cabin from pouring into the cabin-piercing pipe, the deck cable pipe is usually subjected to a waterproof sealing treatment. The above-mentioned waterproof sealing treatment method for the existing cabin pipe is to fill the inside of the cabin-piercing pipe with putty filler from one end of the pipe, but this waterproof sealing method has the following problems:

[0003] 1. The operation of filling the putty filler in the cabin-piercing pipe is difficult, and the amount of putty filler used is large, increasing the waterproof sealing cost of the cabin-piercing pipe;

[0004] 2. The cabin-piercing pipe is only waterproof-sealed by putty plugging material, so that the waterproof sealing method of the cabin-piercing pipe is single, and the waterproof sealing performance needs to be improved. Summary of the Utility Model

[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide a cable pipe assembly passing through a cabin and a ship having the same.

[0006] In a first aspect, the present application provides a cable pipe assembly passing through a cabin, including a cabin-piercing pipe. Both ends of the cabin-piercing pipe are provided with first waterproof seals that can expand upon contact with water, and the first waterproof seals are used to fill the gap between the cable and the inner wall of the cabin-piercing pipe. A filler cavity is formed between the cabin-piercing pipe and the two first waterproof seals. The filler cavity is used to fill waterproof glue, and the waterproof glue located in the filler cavity forms a second waterproof seal after curing. The inner wall of the cabin-piercing pipe is provided with injection holes and exhaust holes arranged at intervals, and both the injection holes and the exhaust holes are communicated with the filler cavity.

[0007] Further, the first waterproof seal is of a flexible structure. A stop member is provided between the second waterproof seal and each first waterproof seal.

[0016] The pipe assembly for cable passing through the cabin provided by the present application and the ship having the same at least have the following beneficial effects:

[0017] 1. By filling first waterproof seals that can expand when encountering water at both ends of the pipe passing through the cabin, a packing cavity is formed between the pipe passing through the cabin and the two first waterproof seals.

[0021] Figure 2 Half-sectional view of the through-hull pipe provided by the embodiment of the present application. Detailed implementation manners

[0022] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that only the parts related to the utility model are shown in the drawings for the convenience of description.

[0023] Please refer to the attached Figure 1-2 The embodiment of the present application provides a cable through-hull pipe assembly. The cable through-hull pipe assembly is configured to be disposed in a wire routing hole formed in a watertight bulkhead 500 for a deck cable to pass through the watertight bulkhead 500. First waterproof seals 110 are provided at both ends of the through-hull pipe 100. The first waterproof seals 110 are used to fill the gap between the cable and the pipe wall of the through-hull pipe 100. The first waterproof seals 110 are water-swellable seals, that is, they will expand in volume when contacting with liquids such as water and form a seal in the through-hull pipe 100 to prevent the passage of water and liquid, thereby realizing the waterproof seal of the through-hull pipe 100. A packing cavity 101 is formed between the through-hull pipe 100 and the two first waterproof seals 110. The packing cavity 101 is used to fill waterproof rubber material, and the waterproof rubber material filled in the packing cavity 101 will form a second waterproof seal 120 after curing, so that there are three layers of waterproof seal structures arranged axially in sequence in the through-hull pipe 100. Injection holes 102 and exhaust holes 103 are arranged at intervals on the pipe wall of the through-hull pipe 100, and both the injection holes 102 and the exhaust holes 103 are communicated with the packing cavity 101. Among them, the injection holes 102 are used to inject the waterproof rubber material into the packing cavity 101, and the exhaust holes 103 are used to discharge the gas in the packing cavity 101 during the injection process.

[0024] The process of the cable through-hull pipe assembly when assembled on the watertight bulkhead 500 is as follows:

[0025] First, the through-hull pipe 100 is installed through the wire routing hole on the watertight bulkhead 500, and the through-hull pipe 100 is welded to the watertight bulkhead 500. Then, the deck cable is passed through the through-hull pipe 100. Next, the first waterproof seals 110 are filled and installed at both ends of the through-hull pipe 100 to fill the gap between the deck cable and the through-hull pipe 100. Then, a liquid is sprayed on the first waterproof seals 110 to make the first waterproof seals 110 expand and seal the through-hull pipe 100. Finally, the waterproof rubber material is injected into the packing cavity 101 through the injection holes 102, and a second seal is formed after the waterproof rubber material is cured at room temperature.

[0026] In this embodiment, a three-layer waterproof sealing structure is axially formed in the cable penetration pipe 100, and the three-layer waterproof sealing structure adopts two different sealing methods, which improves the watertight performance of the cable penetration pipe 100. At the same time, there is no need to fill the entire cable penetration pipe 100 with packing material, reducing the usage amount of the packing material and the difficulty of the filling operation of the packing material in the cable penetration pipe 100, thereby reducing the waterproof sealing cost of the cable penetration pipe 100. In addition, the exhaust hole 103 can discharge the gas in the packing cavity 101 during the process of injecting the packing material into the packing cavity 101. This not only makes the process of injecting the packing material smoother, but also improves the filling rate of the packing material, thereby improving the watertight performance of the second waterproof seal 120 for the cable penetration pipe 100. At the same time, it can also reduce the pressure in the packing cavity 101 during the injection process of the packing material, avoiding the situation of local sealing failure of the first waterproof seal 110 under the action of the pressure in the packing cavity 101.

[0027] Optionally, the diameters of the injection hole 102 and the exhaust hole 103 can both be set to be relatively large, so that both the injection hole 102 and the exhaust hole 103 can be used for injection and exhaust, facilitating the injection operation. Preferably, the diameters of the injection hole 102 and the exhaust hole 103 are set to be the same.

[0028] Optionally, in order to protect the cable penetration pipe 100 and for subsequent maintenance, a sleeve 140 can be sleeved on the outer periphery of the cable penetration pipe 100, and the sleeve 140 is welded to the watertight bulkhead 500. The injection hole 102 and the exhaust hole 103 can both be arranged on one axial side of the sleeve 140 or respectively arranged on both axial sides of the sleeve 140.

[0029] In some embodiments of the present application, the first waterproof seal 110 is of a flexible structure, so that the first waterproof seal 110 can better and faster fill the gap between the cable and the cable penetration pipe 100. A stop member is provided between each first waterproof seal 110 and the second waterproof seal 120. The stop member is connected to the inner pipe wall of the cable penetration pipe 100 and the stop member surrounds the cable. Among them, the stop member is in contact with the first waterproof seal 110. When filling the first waterproof seal 110 into the cable penetration pipe 100, the stop member can limit and stop it, facilitating the filling operation of the first waterproof seal 110 in the cable penetration pipe 100, and also reducing the degree of inward extension of the first waterproof seal 110 when it expands, ensuring the volume of the packing cavity 101. In addition, the two stop members can also adhere to the second waterproof seal 120 and limit the second waterproof seal 120 to prevent the second waterproof seal 120 from being displaced.

[0030] Optionally, the stopper includes a plurality of stopper protrusions 130, which are arranged at intervals along the circumferential direction of the cable penetration pipe 100. The gap between two adjacent stopper protrusions 130 can allow the adhesion between the first waterproof seal 110 and the second waterproof seal 120, increasing the bonding area between the two.
