Description

Technical Field

[0001] The utility model relates to a wiring structure, in particular to a through-hull component assembly. Background Art

[0002] The development of submersibles has shown remarkable progress in recent years, which is not only reflected in the innovation and maturity of technology, but also in the extensive expansion of its application fields. Unmanned submersibles are mainly used for military, deep-sea exploration, etc. In the future, the development of unmanned submersibles will pay more attention to intelligence, autonomy and modularity. At the same time, with the increasing demands for deep-sea exploration, ocean resource development, etc., unmanned submersibles will be applied in more fields. In addition, with the continuous progress of technology and the reduction of costs, the popularization and application of unmanned submersibles will be further accelerated. Manned submersibles such as submarines can be used not only for military purposes, but also for deep-sea scientific research and even civilian underwater sightseeing.

[0003] The importance of submersible sealing is reflected in many aspects, which ensure that the submersible can safely and effectively perform tasks in the underwater environment and guarantee the safety of passengers; when the submersible is working underwater, it faces a complex and changeable underwater environment, including water pressure, water flow and temperature changes, etc. A submersible with good sealing performance can effectively isolate these external factors and maintain the stability of the internal environment. A stable internal environment is crucial for the electronic devices and precision instruments inside the submersible, which can prevent equipment damage or performance degradation caused by fluctuations in the external environment. For example, the outer sidewall of the current submersible generally has auxiliary devices such as indicator lights and sensors, and the wires of these auxiliary devices need to be sealed when passing through the sidewall of the submersible, such as a sealed joint. However, the current sealed joint will cause water to flow into the submersible along the wire gap during long-term underwater work. In addition, once the wires at the sealed part are broken due to collision, etc., the entire sealed joint needs to be replaced during maintenance, which will not only exert extra stress on the sidewall of the submersible and damage its structure, but also cause waste of the sealed joint and cannot effectively save materials and reduce costs. Summary of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a through-hull component assembly.

[0005] To achieve the above purpose, the technical solution of the utility model is: a through-hull component assembly, including a fixed cylinder and a protective cylinder fixed at one end of the fixed cylinder, multiple wires penetrate through a sealing sleeve ring, the inside of the sealing sleeve ring outside the wires is filled with sealing glue, and the sealing sleeve ring and multiple wires penetrate and are fixed inside the fixed cylinder.

[0006] Further, an external thread cylinder is screwed inside the fixed cylinder at the outer end of the sealing sleeve ring, and the external thread cylinder is used to tightly press the sealing sleeve ring in the fixed cylinder, and each wire penetrates through the external thread cylinder.

[0007] Further, one end of the protective cylinder is provided with a connecting cylinder vertically communicating with its body. The connecting cylinder is sleeved on the end of the fixed cylinder, and a wire passing opening for passing a wire is provided at the end of the fixed cylinder at this position.

[0008] Further, multiple sealing rings in contact with the inner side wall of the fixed cylinder are arranged on the periphery of the sealing sleeve ring.

[0009] Further, the fixed cylinder is provided with a nut structure with a diameter larger than that of the body, and the sealing sleeve ring is located on the support platform inside the nut structure.

[0010] Further, a sealing washer is embedded in the end face of one end of the nut structure away from the protective cylinder.

[0011] Further, an external thread structure is provided on the outer side wall of one end of the fixed cylinder away from the protective cylinder, and a sealing ring is embedded in the outer side wall of the main body of the fixed cylinder between the external thread structure and the nut structure.

[0012] Further, symmetric long-strip adjustment openings are formed in the outer end face of the external thread cylinder.

[0013] Further, the fixed cylinder is made of stainless steel, and the protective cylinder is made of plastic.

[0014] Through the above settings, the wire of the present utility model is fixedly connected with the sealing sleeve ring through sealant, which not only forms a sealing effect around the wire, but also makes the wire and the sealing sleeve ring form an integral structure. In this way, if the wire breaks and needs to be replaced, only the sealing sleeve ring needs to be removed, and there is no need to replace the entire fixed cylinder and protective cylinder. When replacing, there is no need to remove the fixed cylinder, effectively avoiding the sealing failure of the fixed cylinder part caused by removing the fixed cylinder, and at the same time avoiding damage to the side wall of the submersible caused by disassembling the fixed cylinder. It not only saves costs and reduces the replacement difficulty, but also can effectively guarantee the strength and airtightness of the side wall of the submersible.

[0020] As Figures 1-4As shown in the figure, a cabin-piercing component assembly includes a fixed cylinder 1 and a protective cylinder 2 fixed to one end of the fixed cylinder 1. A plurality of wires 3 penetrate through a sealing collar 4, and the inside of the sealing collar 4 outside the wires 3 is filled with a sealing glue 5. The sealing collar 4 and the plurality of wires 3 penetrate and are fixed inside the fixed cylinder 1. The fixed cylinder 1 is made of stainless steel, and the protective cylinder 2 is made of plastic. One end of the protective cylinder 2 is provided with a connecting cylinder 7 vertically communicating with its body. The connecting cylinder 7 is sleeved on the end of the fixed cylinder 1, and the end of the fixed cylinder 1 at this position is provided with a wire through-hole 8 for the wires 3 to pass through. In this way, the wires 3 and the sealing collar 4 are fixedly connected by the sealing glue 5, which not only forms a sealing effect around the wires 3, but also makes the wires 3 and the sealing collar 4 form an integral structure. In this way, if the wires 3 are broken and need to be replaced, only the sealing collar 4 needs to be removed, and there is no need to replace the entire fixed cylinder 1 and the protective cylinder 2.

[0021] In order to facilitate the fixation of the sealing collar 4 and facilitate the removal of the entire sealing collar 4 and the plurality of wires 3 during replacement, an external thread cylinder 6 is screwed into the outer end of the fixed cylinder 1. The external thread cylinder 6 is used to press the sealing collar 4 in the fixed cylinder 1, and each wire 3 penetrates through the external thread cylinder 6. The outer end face of the external thread cylinder 6 is provided with symmetrically arranged long strip-shaped adjustment openings (not shown). A plurality of sealing rings 9 in contact with the inner side wall of the fixed cylinder 1 are arranged on the periphery of the sealing collar 4, which facilitates rotating the entire external thread cylinder 6 by pushing the long strip-shaped adjustment openings, so as to facilitate tightening the external thread cylinder 6 during installation. After tightening, the sealing rings 9 can be further pressed to achieve a sufficient sealing effect.

[0022] In order to facilitate screwing the entire fixed cylinder 1, the fixed cylinder 1 is provided with a nut structure 10 with a diameter larger than its body. The sealing collar 4 is located on the support platform inside the nut structure 10. A sealing washer 11 is embedded in the end face of one end of the nut structure 10 away from the protective cylinder 2. An external thread structure 12 is arranged on the outer side wall of one end of the fixed cylinder 1 away from the protective cylinder 2, and a sealing ring 13 is embedded in the outer side wall of the main body of the fixed cylinder 1 between the external thread structure 12 and the nut structure 10. When the fixed cylinder 1 is fixed to the side wall of the submersible equipment, the sealing washer 11 is located at the outer side wall of the submersible equipment to perform a primary seal at the outer side wall of the fixed cylinder 1 and the submersible equipment, and the sealing ring 13 can perform a secondary seal at the position where the fixed cylinder 1 penetrates the side wall of the submersible equipment or inside.
