Description

Technical Field

[0001] The utility model relates to the technical field of ship sonar, in particular to a sealing module suitable for a cable pipe and a sonar cable pipe. Background Art

[0002] When a ship uses a 3D sonar, based on its working principle, it needs to be installed at a position below the waterline by 1 m or more at the bow of the ship. The sonar is connected to the cab through a cable, and a cable pipe is also arranged outside the cable to protect the cable. The cable pipe is connected from the bow peak tank to the sonar fairing in the water. There is a space between the cable pipe and the cable for water flow to enter to cool the cable. In order to prevent seawater from entering the cabin through the cable pipe, a watertight stuffing box is arranged at the end of the cable pipe to seal the gap between the cable and the cable pipe and prevent water flow from entering the cabin through the cable pipe. However, when the ship is traveling at high speed, seawater will quickly flow into the cable pipe, and the watertight stuffing box cannot withstand the large water pressure brought by the water flow, thus it is extremely easy to cause leakage, which will further pollute the environment inside the cabin. At the same time, the air existing in the cable pipe will hinder the water flow, making the water flow unable to effectively cool the cable in the cable pipe. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sealing module suitable for a cable pipe and a sonar cable pipe, which can prevent leakage and effectively seal the cable.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An expansion member, the expansion member being arranged on the ferrule assembly, the expansion member being capable of applying a force to the ferrule assembly, and the ferrule assembly being capable of expanding radially under the action of the force of the expansion member so that the outer circumferential surface and the innermost seal sheet group respectively abut against the inner wall of the installation pipe and the outer wall of the cable.

[0008] Preferably, the sealing module suitable for a cable pipe further comprises an end plate, the end plate being arranged at the end of the ferrule assembly, the outer diameter of the end plate being larger than the inner diameter of the installation pipe, and the end plate being used for axially abutting against the installation pipe along the installation pipe.

[0010] The innermost first sealing layer and the innermost second sealing layer enclose to form the through hole. A plurality of expansion members are arranged on both the first ferrule and the second ferrule.

[0011] Preferably, the end plate includes a first end plate and a second end plate. The first end plate is arranged on the first ferrule, and the second end plate is arranged on the second ferrule.

Since a plurality of sealing sheet groups are stacked, and adjacent two sealing sheet groups can be peeled off from each other, different outer diameter cables can be applied by peeling the sealing sheet groups, which is convenient to operate and has strong practicability. Since expansion members are arranged on the ferrule assembly, the expansion members can apply a force to the ferrule assembly, and the ferrule assembly can expand radially under the action of the expansion members, so that the outer peripheral surface of the ferrule assembly abuts tightly against the inner wall of the installation pipe, thereby tightly fixing the sealing module at the port of the installation pipe.

[0033] The following further describes the present utility model in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0034] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements.

[0035] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0036] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", and "left" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0037] Such as Figures 1 to 3As shown in the figure, the present utility model provides a sealing module applicable to a cable pipe. The sealing module applicable to the cable pipe is arranged at the end of the installation pipe 100 and includes a ferrule assembly 1, a sealing sheet group 2 and an expansion member 3. The ferrule assembly 1 has an inner peripheral surface and an outer peripheral surface. A plurality of sealing sheet groups 2 are stacked on the inner peripheral surface. The plurality of sealing sheet groups 2 can be peeled off from each other. The innermost sealing sheet group 2 encloses to form a through hole 13 for passing through the cable. The expansion member 3 is arranged on the ferrule assembly 1. The expansion member 3 can apply a force to the ferrule assembly 1. The ferrule assembly 1 can expand radially under the action of the force of the expansion member 3 so that the outer peripheral surface and the innermost sealing sheet group 2 are respectively abutted against the inner wall of the installation pipe 100 and the outer wall of the cable. In this embodiment, the ferrule assembly 1 is arranged at the end of the cable pipe and is located between the installation pipe 100 and the cable. The ferrule assembly 1 has an inner peripheral surface and an outer peripheral surface. A plurality of sealing sheet groups 2 are stacked on the inner peripheral surface. The innermost sealing sheet group 2 encloses to form a through hole 13. Therefore, the cable can pass through the through hole 13 and be arranged on the sealing module. Since a plurality of sealing sheet groups 2 are stacked and adjacent two sealing sheet groups 2 can be peeled off from each other, cables with different outer diameters can be adapted by peeling off the sealing sheet groups 2, which is convenient to operate and has strong practicability. Since the expansion member 3 is arranged on the ferrule assembly 1, the expansion member 3 can apply a force to the ferrule assembly 1, and the ferrule assembly 1 can expand radially under the action of the force of the expansion member 3 so that the outer peripheral surface of the ferrule assembly 1 is abutted tightly against the inner wall of the installation pipe 100, thereby expanding and fixing the sealing module tightly at the port of the installation pipe 100. At the same time, the innermost sealing sheet group 2 on the inner peripheral surface of the ferrule assembly 1 can be abutted tightly against the outer wall of the cable, so that the space between the installation pipe 100 and the cable is filled by the ferrule assembly 1, thereby playing an effective sealing role.

[0038] Further, as Figure 1 shown, the sealing module applicable to the cable pipe further includes an end plate 4. The end plate 4 is arranged at the end of the ferrule assembly 1. The outer diameter of the end plate 4 is larger than the inner diameter of the installation pipe 100. The end plate 4 is used for axially abutting against the installation pipe 100 along the installation pipe 100. In this embodiment, the end plate 4 is made of stainless steel and is arranged at the end of the ferrule assembly 1. During installation, the staff inserts the ferrule assembly 1 into the installation pipe 100. Since the outer diameter of the end plate 4 is larger than the inner diameter of the installation pipe 100, the end plate 4 will axially abut against the pipe wall at the end of the installation pipe 100, thereby playing a further limiting and fixing role and preventing the whole sealing module from being inserted into the installation pipe 100, which is convenient for subsequent disassembly.

[0039] Specifically, as Figures 1 to 3As shown in the figure, the ferrule assembly 1 includes a first ferrule 11 and a second ferrule 12 which are oppositely arranged. The sealing sheet group 2 includes a first sealing layer 21 and a second sealing layer 22. The first sealing layer 21 is arranged on the first ferrule 11, and the second sealing layer 22 is arranged on the second ferrule 12. The innermost first sealing layer 21 and the innermost second sealing layer 22 enclose a through hole 13. A plurality of expansion members 3 are arranged on both the first ferrule 11 and the second ferrule 12. In this embodiment, the ferrule assembly 1 is of a hollow cylinder structure, which is composed of the relative splicing of the first ferrule 11 and the second ferrule 12. The cross-sections of the first ferrule 11 and the second ferrule 12 are both semi-circular. Correspondingly, the sealing sheet group 2 includes a first sealing layer 21 and a second sealing layer 22. The first sealing layer 21 is arranged on the first ferrule 11, and the second sealing layer 22 is arranged on the second ferrule 12. When installing this sealing module, the staff respectively clamp the first ferrule 11 and the second ferrule 12 on the cable of the installation pipe 100, and adjust the positions of the first ferrule 11 and the second ferrule 12 so that the two are relatively positioned to completely wrap the cable circumferentially. Then, the two are respectively tightened and fixed at the port of the installation pipe 100 through the expansion members 3 on the first ferrule 11 and the second ferrule 12. Specifically, both the first sealing layer 21 and the second sealing layer 22 are made of ethylene propylene diene monomer (EPDM). EPDM is a high-performance synthetic rubber product, which has excellent electrical insulation performance and aging resistance, and also has excellent electrical insulation performance. A plurality of layers of the first sealing layer 21 are laminated on the inner peripheral surface of the first ferrule 11. Adjacent two first sealing layers 21 are connected by bonding. The outermost first sealing layer 21 is also arranged on the inner peripheral surface of the first ferrule 11 by bonding. Similarly, a plurality of layers of the second sealing layer 22 are arranged on the inner peripheral surface of the second ferrule 12 in the same way. When installing this sealing module, the staff peels the first sealing layer 21 and the second sealing layer 22 according to the thickness of the cable. For each peeled layer of the first sealing layer 21 and the second sealing layer 22, the inner diameter of the through hole 13 is larger, and the diameter of the cable that can be sealed is also larger. The installation method of the splicing of the first ferrule 11 and the second ferrule 12 has a flexible assembly method, reduces the installation difficulty, and is also convenient for peeling the sealing sheet group 2.

[0040] Specifically, as Figure 1 shown, the end plate 4 includes a first end plate 41 and a second end plate 42. The first end plate 41 is arranged on the first ferrule 11, and the second end plate 42 is arranged on the second ferrule 12. In this embodiment, the end plate 4 includes the first end plate 41 and the second end plate 42 which are respectively arranged on the first ferrule 11 and the second ferrule 12. The first end plate 41 and the second end plate 42 are both semi-circular and can respectively abut against the end of the installation pipe 100.

[0041] Furthermore, as Figure 1As shown, a plurality of expansion pieces 3 are provided, and the plurality of expansion pieces 3 are evenly spaced and arranged on the ferrule assembly 1. In this embodiment, the expansion piece 3 is arranged on the ferrule assembly 1 along the axial direction of the ferrule assembly 1, and the staff inserts the expansion piece 3 into the ferrule assembly 1 along the axial direction so that the side wall of the ferrule assembly 1 expands radially to both sides, thereby realizing the expansion and sealing of the ferrule assembly 1, the mounting tube 100 and the cable; specifically, the plurality of expansion pieces 3 are evenly spaced and arranged on the ferrule assembly 1, thereby ensuring good sealing everywhere on the ferrule assembly 1.

[0042] Further, the expansion piece 3 is threadedly matched with the ferrule assembly 1. In this embodiment, the expansion piece 3 is matched with the ferrule assembly 1 by threaded connection, which has a simple structure and is easy to operate; specifically, a threaded hole is axially provided on the ferrule assembly 1, and the expansion piece 3 is a screw that gradually becomes thicker from the tail to the head. As the expansion piece 3 is continuously screwed into the threaded hole of the ferrule assembly 1, the ferrule assembly 1 will deform and expand radially, thereby achieving expansion and sealing with the installation tube 100 and the cable.

[0043] Specifically, the ferrule assembly 1 is made of rubber. In this embodiment, the first ferrule 11 and the second ferrule 12 are both made of rubber with high elasticity. When the expansion member 3 is screwed into the first ferrule 11 and the second ferrule 12, the first ferrule 11 and the second ferrule 12 are deformed and expanded radially, respectively, so as to achieve expansion sealing with the installation tube 100 and the cable.

[0044] like Figure 4 As shown, this embodiment also provides a sonar cable pipe, which includes a mounting pipe 100 and the above-mentioned sealing module suitable for the cable pipe. The sonar cable pipe can well seal the cable and the cable pipe to prevent water from entering the cabin through the gap between the cable and the cable pipe.

[0045] Further, one end of the mounting tube 100 is arranged on the fairing 300 of the sonar 200, and the other end of the mounting tube 100 extends into the cabin. In this embodiment, the mounting tube 100 is used to accommodate the cable of the sonar 200, one end of the cable is connected to the sonar 200 in the water, and the other end is connected to the cab, one end of the mounting tube 100 is connected to the fairing 300 of the sonar 200, and the other end of the mounting tube 100 extends into the cabin; during the voyage of the ship, seawater can enter the mounting tube 100 through the fairing 300, and continue to flow to the end of the mounting tube 100 under the action of water pressure, thereby cooling the cable in the mounting tube 100.

[0046] Furthermore, if Figure 4As shown, an air vent is provided at the end of the installation pipe 100 near the sealing module suitable for the cable pipe, and an air vent cock 110 is screwed onto the air vent. In this embodiment, the installation pipe 100 is provided with an air vent, and an air vent cock 110 is arranged on the air vent; the staff can discharge the air inside the installation pipe 100 by unscrewing the air vent cock 110, avoiding the obstruction of seawater entry and the circulating flow inside the installation pipe 100 due to the presence of air, thereby effectively ensuring the cooling effect of seawater on the cable in the cable pipe 100.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
