Description

Technical Field

[0001] The invention relates to a heavy underwater suspended photoelectric hybrid cable, belonging to the technical field of electrical hybrid cables. Background Art

[0002] Optical-electric hybrid cable is a new access method suitable for communication access network systems. It combines power transmission copper wires with optical fibers, and can simultaneously solve the problems of broadband access, equipment power consumption, and signal transmission at one time. Optical-electric hybrid cable provides power supply to remote devices more safely and reliably, with small optical-electric loss and low electricity cost.

[0003] With the development of ocean exploration technology, especially the development of deep-sea exploration and military industry, underwater vehicles are used more and more widely, replacing humans to challenge harsh environments and work in seas full of complex underwater terrain. Underwater vehicle machine detection equipment has become an important tool to challenge the ocean. The underwater environment on the seabed is harsh and not suitable for ordinary cables. Underwater vehicles and their monitoring equipment are equipped with optical cables or cables used by machines. However, when the hybrid cable is placed in the sea, it will sink to the bottom due to its own gravity, resulting in the inability to work normally. At the same time, impurities in the sea will enter the interior of the cable. If it is sealed directly, when the interior of the cable needs to be disassembled, it will have a certain impact on the staff. Summary of the invention

[0004] The purpose of the present invention is to provide a heavy-duty underwater suspended optoelectronic hybrid cable. The present invention has a simple structure and is easy to use. When in use, it can float in the sea. At the same time, protective measures are added to facilitate disassembly to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A heavy-duty underwater suspended photoelectric hybrid cable comprises a main body, the outer side of the main body is fixedly connected to a cable rod, one end of the cable rod away from the main body is fixedly connected to a connecting tube, the end of the main body away from the cable rod is fixedly connected to an air bag, the end of the air bag close to the inside of the main body is fixedly connected to an air pipe, the outer side of the air pipe is fixedly connected to a conduction tube, the end of the conduction tube away from the air pipe is fixedly connected to a floating bag, the outer side of the main body is fixedly connected to a connecting ring, a slot is provided inside the connecting ring, a positioning block is clamped inside the slot, a guide rod is fixedly connected to the bottom of the positioning block, an extrusion cover is fixedly connected to the end of the guide rod away from the positioning block, a fixing ring is fixedly connected to the outer side of the connecting tube, a push rod is fixedly connected to the outer side of the fixing ring, a protective cover is fixedly connected to the inner side of the connecting tube, a threaded rod is fixedly connected to the inner side of the cable rod, a threaded ring is provided inside the cable rod, and a cable is fixedly installed inside the cable rod.

[0007] Furthermore, one end of the trachea away from the airbag is fixedly connected to the inside of the body, and the conductive tube is evenly distributed on the outside of the trachea, so that the gas inside the airbag enters the trachea inside the body by squeezing the airbag.

[0008] Furthermore, the number of the floating bags is the same as that of the conducting tubes, and the floating bags are evenly distributed on the outside of the main body. The air tube and the conducting tube are used in coordination so that gas inside the floating bags can enter, thereby achieving a floating effect.

[0009] Furthermore, the number of the slots and the positioning blocks is the same, and the slots and the positioning blocks are symmetrically distributed on both sides of the connection ring, and the positioning blocks are driven to move by the movement of the guide rods, so that the positioning blocks are engaged in the slots.

[0010] Furthermore, the number of the guide rods and the extrusion covers is the same, and the extrusion covers are symmetrically distributed on the outside of the airbag. The movement of the guide rods drives the extrusion covers to move, so that the extrusion covers squeeze the airbag, allowing the gas inside the airbag to enter the inside of the trachea.

[0011] Furthermore, there are two push rods, and the push rods are symmetrically distributed on the outside of the fixing ring. The fixing ring is driven to move by the rotation of the connecting tube, so that the push rods move on the outside of the fixing ring.

[0012] Furthermore, the threaded rod and the threaded ring are on the same plane, and the threaded rod is rotatably connected to the inside of the threaded ring, and the threaded rod rotates inside the threaded ring, thereby driving the fixed ring to move.

[0013] Furthermore, the protective cover is slidably connected to the outside of the cable rod, and the inner diameter of the protective cover is slightly larger than the outer diameter of the cable rod.

[0014] Furthermore, the threaded ring is located at the exact center of the cable rod, and the cables are evenly distributed inside the cable rod.

[0015] Furthermore, the connecting pipe is located at the center of the fixed circle, and one end of the threaded rod away from the connecting pipe is fixedly connected to the inside of the protective cover.

[0016] The beneficial effects of the present invention are:

[0017] The present invention is provided with a connecting ring, and a card groove is provided inside the connecting ring. By pushing the guide rod, the guide rod drives the positioning block to be connected to the card groove of the connecting ring, and the movement of the guide rod drives the extrusion cover to move. The movement of the extrusion cover squeezes the air bag outside the main body, so that the gas inside the air bag enters the trachea, and the gas enters the trachea, so that the gas enters the floating bag outside the conductive tube. At this time, when the main body enters the seawater, it will automatically float up, which can ensure that the equipment can work normally and will not sink to the seabed. By connecting the protective cover to the cable pole, impurities in the water are prevented from entering the inside of the cable pole. When the inside of the cable pole needs to be disassembled, the connecting tube is rotated to drive the connecting tube to rotate, and the threaded rod is rotated to move out of the threaded circle inside the cable pole. The movement of the connecting tube drives the push rod to move, so that the push rod drives the protective cover to move out from the outside of the cable pole, thereby achieving the effect of convenient disassembly.
