Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship cable, in particular to a marine equipment wire inlet device. BACKGROUND

[0002] Marine cable is a kind of wire and cable for river and sea ships and offshore or marine buildings for power, lighting, control, communication transmission, including marine power cable, marine control cable, marine communication cable, etc. Generally, the laying space of marine cable is limited, so the armored structure adopts wire braiding, which is the biggest difference in structure from ordinary land power, control and communication cables. The filler type cable inlet device is generally installed at the connection between the cable port and the explosion-proof equipment. The filler is directly installed in the inner cavity and pressed in the inner cavity through bolts, so as to achieve the purpose of sealing and prevent external grease, water stains or some medium from entering and interfering with the cable, thereby affecting the operation and service life of the explosion-proof equipment. It is generally suitable for places with relatively harsh environment, such as offshore oil platforms and equipment with high explosion-proof grade requirements.

[0003] However, in shipbuilding, many devices in the living area need to be installed on the bulkhead panel. The thickness of the bulkhead panel causes the length of the device wire inlet filler to be insufficient after passing through the bulkhead panel, and it is difficult to disassemble and maintain. At the same time, the device protection grounding cannot be realized due to the reason that the wire inlet filler is inside the bulkhead panel. SUMMARY

[0004] In view of the existing problems, the present application provides a marine equipment wire inlet device, which can effectively solve the problems raised in the background art when used in combination.

[0005] To solve the above problems, the present application adopts the following technical solutions:

[0006] The marine equipment wire inlet device comprises a wire inlet filler and an armored cable. The inside of the wire inlet filler is provided with a wire distribution arrangement mechanism. The wire distribution arrangement mechanism comprises a limiting sleeve ring, a positioning installation grommet and a center installation seat. Cable separation rods are arranged in an array on the outside of the center installation seat inside the limiting sleeve ring. A receiving groove is formed at one end of the cable separation rod close to the inside of the limiting sleeve ring. An extension rod is arranged in the receiving groove. A positioning spring is arranged between the extension rod and the cable separation rod. A first limiting sliding block is arranged on the outside end of the extension rod. A second limiting sliding block is arranged on the outside end of the cable separation rod. A second limiting groove is formed in the inside of the center installation seat on one side of the second limiting sliding block. A first limiting groove is formed in the inside of the limiting sleeve ring on one side of the first limiting sliding block. An outer installation insertion hole is formed in the limiting sleeve ring on one side through the first limiting groove. An inner installation insertion hole is formed in the center installation seat on one side through the second limiting groove.

[0007] As a further scheme of the present application: the wiring gland comprises a wiring barrel, a compression nut, an extension sleeve mounted on one end of the wiring barrel close to one side end of the compression nut, and an inlet connector mounted on an end of the extension sleeve.

[0008] As a further scheme of the present application: the compression nut is provided with a mounting cover plate, the mounting cover plate is provided with a grounding wire connecting column on one side close to the wiring barrel, and the wiring barrel is provided with a closing cover plate on one side corresponding to the grounding wire connecting column.

[0009] As a further scheme of the present application: one end of the telescopic rod is provided with a limiting pad plate inside the receiving groove, and the positioning spring is fixedly connected with the cable separating rod and the telescopic rod.

[0010] As a further scheme of the present application: the first limiting sliding block is fixedly connected with the telescopic rod, and the second limiting sliding block is fixedly connected with the cable separating rod.

[0011] As a further scheme of the present application: the cable separating rod is movably connected with the second limiting groove through the second limiting sliding block, and the telescopic rod is movably connected with the first limiting groove through the first limiting sliding block.

[0012] As a further scheme of the present application: the compression nut is fixedly connected with the inlet connector.

[0013] As a further scheme of the present application: the grounding wire connecting column is fixedly connected with the mounting cover plate, and the closing cover plate is fixedly connected with the wiring barrel.

[0014] As a further scheme of the present application: the outer diameter of the limiting sleeve ring is smaller than the inner diameter of the wiring gland.

[0015] As a further scheme of the present application: the positioning mounting pad ring is fixedly connected with the limiting sleeve ring, and the positioning mounting pad ring is a rubber member.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1. The closing cover plate on the outer side of the wiring barrel is closed at the end of the grounding wire connecting column, so that the closing cover plate and the mounting cover plate limit the grounding wire outside the grounding wire connecting column, achieving the purpose of grounding, and thus the grounding wire does not need to be sleeved with the armored cable.

[0018] 2. Install the first limiting slider at the end of the telescopic rod into the first limiting groove, corresponding to the position of the external mounting hole. Then, adjust the installation position of the cable separator rod and the telescopic rod between the limiting collar and the central mounting seat. Therefore, the number of cable separator rods and telescopic rods installed between the limiting collar and the central mounting seat can be selected, thereby limiting the installation of different numbers of cables.

[0019] 3. By pushing the telescopic rod as a whole into the storage groove, the positioning spring is compressed and deformed, and the first limiting slider at the end of the telescopic rod is installed into the first limiting groove, corresponding to the position of the external mounting hole. This ensures the stability of the cable separator rod and the telescopic rod after installation.

[0020] 4. An extension sleeve is added to the outer side of the inlet connector at one end of the wiring screw cylinder to facilitate the overall installation of the wiring stuffing box. After installation, it facilitates the installation and disassembly of the clamping nut and the inlet connector. Sealing filler is then added to the inside of the wiring screw cylinder to reduce gaps at the wiring position. Attached Figure Description
