Description

Technical Field

[0001] The invention relates to the field of ship cables, in particular to a ship equipment incoming line device. Background Art

[0002] Marine cable is a kind of wire and cable used for power, lighting, control and communication transmission on various ships and offshore or offshore buildings in rivers and seas, including marine power cable, marine control cable, marine communication cable, etc. Usually, the laying space of marine cables is limited, so the armored structure adopts metal wire weaving, which is the biggest difference in structure from ordinary land-based power, control and communication cables. The stuffing type cable entry device is generally installed at the connection between the cable port and the explosion-proof equipment. The stuffing is directly loaded into the inner cavity and compacted in the inner cavity by bolts to achieve the purpose of sealing. At the same time, it can prevent external grease, water stains, or some media from entering and interfering with the cable, which will affect the operation of the explosion-proof equipment and the service life of the explosion-proof equipment. It is generally suitable for places with relatively harsh environments, such as offshore oil platforms, and equipment with relatively high explosion-proof requirements.

[0003] However, in ship construction, many devices in the living area need to be installed on the enclosure panels. The thickness of the enclosure panels results in insufficient length of the equipment incoming wiring stuffing box after passing through the enclosure panels, making disassembly and maintenance difficult. At the same time, the protective grounding of the equipment cannot be achieved because the wiring stuffing box is inside the enclosure panel. Summary of the invention

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

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

[0006] A line inlet device for marine equipment includes a wiring stuffing box and an armored cable. A line dividing and arranging mechanism is arranged inside the wiring stuffing box. The line dividing and arranging mechanism includes: a limiting collar, a positioning and mounting gasket ring, and a center mounting seat. A cable dividing rod is installed in an array on the outside of the center mounting seat and located inside the limiting collar. A storage groove is provided at one end of the cable dividing rod close to the inner side of the limiting collar. A telescopic rod is arranged inside the storage groove. A positioning spring is installed between the telescopic rod and the cable dividing rod. A first limiting slider is installed on the outer end of the telescopic rod. A second limiting slider is installed on the outer end of the cable dividing rod. One side of the second limiting slider is located inside the center mounting seat and is provided with a second limiting groove. One side of the first limiting slider is located inside the limiting collar and is provided with a first limiting groove. One side of the limiting collar penetrates the first limiting groove and is provided with an outer mounting socket. One side of the center mounting seat penetrates the second limiting groove and is provided with an inner mounting socket.

[0007] As a further solution of the present invention: the wiring stuffing box includes: a wiring screw barrel and a clamping nut, one end of the wiring screw barrel is installed with an extension sleeve on one side end close to the clamping nut, and the end of the extension sleeve is installed with an inlet connector.

[0008] As a further solution of the present invention: a mounting cover is installed on the outer side of the clamping nut, a bottom line connecting column is installed on the side of the mounting cover close to the terminal screw barrel, and a closed cover is installed on the side of the outer side of the terminal screw barrel corresponding to the bottom line connecting column.

[0009] As a further solution of the present invention: a limiting pad is installed at one end of the telescopic rod inside the storage groove, and the positioning spring is fixedly connected to the cable dividing rod and the telescopic rod.

[0010] As a further solution of the present invention: the first limit sliding block is fixedly connected to the telescopic rod, and the second limit sliding block is fixedly connected to the cable dividing rod.

[0011] As a further solution of the present invention: the cable dividing rod is movably connected to the second limiting groove through the second limiting sliding block, and the telescopic rod is movably connected to the first limiting groove through the first limiting sliding block.

[0012] As a further solution of the present invention: the clamping nut is engaged and fixedly connected with the inlet connector.

[0013] As a further solution of the present invention: the bottom line connecting column is fixedly connected to the installation cover plate, and the closing cover plate is fixedly connected to the wiring screw barrel.

[0014] As a further solution of the present invention: the outer diameter dimension length of the limiting collar is smaller than the inner diameter dimension length of the wiring stuffing box.

[0015] As a further solution of the present invention: the positioning and mounting gasket ring is fixedly connected to the limiting sleeve ring, and the positioning and mounting gasket ring is a rubber material component.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The closed cover plate on the outside of the terminal screw barrel will be closed at the end position of the bottom line connecting column as a whole. Therefore, the closed cover plate and the installation cover plate will be sleeved on the grounding wire limiter outside the bottom line connecting column as a whole to achieve the purpose of grounding. Therefore, there is no need to sleeve the grounding cable from the end of the armored cable.

[0018] 2. Install the first limit slider at the end of the telescopic rod into the first limit groove corresponding to the position of the external mounting socket, and then adjust the installation position of the cable dividing rod and the telescopic rod as a whole between the limit ring and the center mounting seat. Therefore, the number of cable dividing rods and telescopic rods to be installed between the limit ring and the center 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 slot, after the positioning spring is controlled to be squeezed and deformed, the first limit slider at the end of the telescopic rod is installed into the first limit slot as a whole corresponding to the position of the external mounting socket, which can ensure the stability of the cable separator rod and the telescopic rod after installation.

[0020] 4. An extension sleeve is added to the outer end of the inlet connection body at one end of the wiring screw barrel to facilitate the overall installation of the wiring stuffing box. After the installation is completed, it can facilitate the installation and removal of the clamping nut and the inlet connection body, and fill the inside of the wiring screw barrel with sealed filler to reduce the gap at the wiring position.
