Description

Technical Field

[0001] The utility model belongs to the technical field of cable shells, in particular to a shell used for submarine cable connections. Background Art

[0002] Submarine cables are cables wrapped in insulating material and laid on the seabed for telecommunications transmission. In areas of tectonic plate movement, natural disasters such as earthquakes and tsunamis often occur, which can exert concentrated forces on submarine cables and cause them to break. In areas with strong undersea currents, the long-term erosion of seabed silt by the undercurrents can eventually cause submarine cables to become suspended in mid-air, where they can break under the force of lateral undercurrents. Furthermore, during the laying process, submarine cables often encounter poor seabed conditions such as bedrock, making it impossible to lay the cables underground and providing adequate protection.

[0003] When an existing cable breaks, it is usually necessary to reconnect the cable. After the connection is completed, the interface is exposed and needs to be processed before it can be used. However, the connection point is relatively weak and the deep seabed is more complex, so the connection point needs to be protected. Therefore, a shell for submarine cable connection is proposed. Summary of the Invention

[0004] The purpose of the utility model is to provide a shell for submarine cable connection to solve the existing problems.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A connector is provided at the connection of the cable body, and a fixing device is threadedly connected to the bottom surface of the lower protective shell. The inclined surfaces on opposite sides of the fixing device are provided with installation grooves, and the inclined surfaces on opposite sides of the fixing device are provided with fixing grooves. A moving rod is provided in the fixing groove, and a slider is inserted through the peripheral side of the moving rod. An insertion block is provided on one side of the slider, and a spring is sleeved on the peripheral side of the moving rod. A fixing plate is hinged in the installation groove, and a notch is provided on the bottom surface of the installation groove.

[0008] The support assembly includes a main body, an upper slide rod and a lower slide rod. Locking parts are provided at the upper and lower ends of the main body. A limiting groove is provided on the peripheral side of the locking part. A clamping block is hinged in the limiting groove. A torsion spring is provided at the hinge between the limiting groove and the clamping block. Multiple groups of tooth grooves are provided on the peripheral side of the upper slide rod and the lower slide rod.

[0009] The rotating shaft includes an inner ring and an outer ring. The peripheral side surface of one end of the bolt is fixedly connected to the peripheral side surface of the rotating shaft. The outer ring of the rotating shaft is fixedly connected to the peripheral side surface of the upper clamping plate. The upper clamping plate is an arc-shaped plate structure. The lower protective shell and the upper protective shell have the same structure.

[0010] A slot is provided on one side of the fixing plate, the position of the slot is adapted to the position of the insert block, one end of the spring is fixedly connected to one side of the inner wall of the fixing slot, and the other end of the spring is fixedly connected to one side of the slider.

[0011] The upper end of the upper slide rod is provided with a hinge seat, and the hinge seat is provided in the slot and hinged to the slot. The lower end of the lower slide rod is hinged to the upper surface of the fixed plate. The shape and size of the tooth groove are adapted to the card block, and the tooth groove is engaged with the card block. The upper end of the lower slide rod is inserted into the locking piece and slides with the locking piece. The lower end of the upper slide rod is inserted into the locking piece and slides with the locking piece.

[0012] The utility model has the following beneficial effects:

[0013] The utility model places the cable body and the connector inside the lower protective shell, and then covers the upper protective shell on the upper surface of the lower protective shell and fixes it with screws. At this time, the sealing rings provided on the inner walls of both ends of the upper protective shell are in contact with the surface of the cable body to prevent seawater from entering the interior; then the bolts on the sides of the lower protective shell and the upper protective shell are rotated, and the bolts push the upper clamping plates to clamp each other through the rotating shaft, and the elastic pads and friction blocks in the upper clamping plates are in contact with the surface of the cable body to limit the position and prevent the cable from escaping from the inside.

[0014] When the cable reaches the sand and mud on the seabed and encounters the situation where it is impossible to lay the cable underground, the fixing device is installed on the bottom surface of the lower protective shell by screws, and the fixing plate is rotated. The fixing plate is unfolded by cooperating with the lower slide bar, the main body and the upper slide bar, and then the fixing plate is inserted deep into the sand and mud. The fixing plates on the left and right sides of the fixing device are in an inward-buckling posture to clamp the sand and mud at the bottom of the fixing device, which can provide stable support for the fixing device and reduce the range of movement of the fixing device due to external force impact. The unfolding process of the fixing plate is relatively fast and easy to use.
