Description

TECHNICAL FIELD

[0001] The present application relates to a connector for connecting a buoy and a submarine cable for landing and tower operation of the submarine cable. BACKGROUND

[0002] Currently, in the landing and tower operation of the submarine cable, especially in the tower operation, in order to reduce the drag of the submarine cable, it is generally necessary to avoid the submarine cable from being too much released from the seabed surface, so it is usually necessary to bind the buoy on the landing and tower section of the cable to reduce the weight of the cable and make the cable float in the water. When the cable approaches the end point or the entrance of the J-shaped pipe, it is necessary to manually remove it, which is usually done by a diver underwater to remove the binding or hold a sharp tool to cut off the extension. Because the diver's underwater vision is limited and the underwater construction is inconvenient, it is easy to miss or incompletely remove, which may cause quality and safety hazards and lead to injury of the diver or the buoy that is not cut off being stuck in the pipe entrance.

[0003] In view of the above, a tool is needed for connecting the submarine cable and the buoy, which is convenient for the diver to operate underwater or even directly above the water surface to remove the connection between the submarine cable and the buoy. SUMMARY

[0004] The present application provides a buoy rope disconnectable connector to solve the problem of connecting and disconnecting the submarine cable and the buoy.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present application is: a buoy rope disconnectable connector, which comprises a connector core, a connector front shell, a connector rear shell and a connector safety device. The connector front shell and the connector rear shell wrap the connector core from front to back, and the connector safety device is inserted to form the buoy rope disconnectable connector.

[0006] Further, the buoy rope disconnectable connector has two working states, namely the connector state and the breaker state, and the state is switched by plugging and unplugging the connector safety device.

[0007] Further, the upper end of the connector core is provided with an upper hanging ring, and the lower end is provided with a hook-type breaker, and the hook-type breaker is provided with a breaker blade. The upper hanging ring passes through the rope to connect with the buoy, and the hook-type breaker protects and hides the breaker blade in the connector state under the protection of the connector front and rear shells. At this time, the hook-type breaker can suspend the rope to connect the buoy and the submarine cable.

[0008] Further, the connector core is provided with a core sliding groove and a core limiting groove, and the connector front and rear shells are provided with a shell sliding limiting column. The connector core can be pulled up and down and slid by relying on the core sliding groove and the shell sliding limiting column, and the connector safety device is inserted into the shell safety slot by a safety bolt to clamp the core limiting groove, so that the position of the connector core is fixed and becomes the connector state.

[0009] Further, the latch handle of the connector safety can shield a part of the breaker protection shell, so that the hook-type breaker and the opening of the breaker protection shell are closed; the latch root is provided with a latch pull ring hole, a pull ring or a thin rope can be installed, and the other end of the rope is tied and fixed on the connector to tie the connector safety, so that the safety can be pulled out and also prevented from being lost after being pulled out.

[0010] Further, after the connector safety is pulled out underwater, the floating ball rope breakable connector is converted into a breaker state, the hook-type breaker is pulled out of the breaker protection shell when the upper hanging ring is stressed, so that the rope of the submarine cable directly contacts and is cut off by the breaker blade, and the floating ball rope breakable connector is taken to the water surface by the floating ball and is recycled together.

[0011] The beneficial effects of the present application are:

[0012] The present application solves the problem that the floating ball is difficult to untie when the submarine cable is landed and towered, and improves the convenience and safety of construction operation. BRIEF DESCRIPTION OF DRAWINGS

[0021] The present application will be further described below in combination with the drawings and examples.

[0022] AsFigures 1 to 7 As shown, the floating ball rope breakable connector 1 of the present application is composed of a connector core 2, a connector front shell 3, a connector rear shell 4, and a connector safety 5; wherein the upper part of the connector core 2 is provided with an upper hanging ring 6, the middle part of the connector core 2 has a core sliding groove 7, one side edge has a core limiting groove 8, and the bottom has a hook type breaker 9, and the hook type breaker 9 is inlaid with a breaker blade 10; the connector front shell 3 and the connector rear shell 4 wrap the connector core 2, and the shell sliding limiting column 11 is embedded into the core sliding groove 7, and after the connector safety 5 is inserted into the shell safety insertion slot 12, the complete floating ball rope breakable connector 1 is formed.

[0023] At the same time, as shown, Figure 6 the safety bolt handle 16 of the connector safety 5 can block part of the breaker protection shell 13, so that the opening of the hook type breaker 9 and the breaker protection shell 13 is closed; the root of the safety bolt 14 has a safety bolt pull ring hole 15, which can be installed with a pull ring or a thin rope, and the other end of the rope is tied and fixed on the connector to tether the connector safety 5, so that the safety can be removed, and the safety can also be prevented from being lost after being removed.

[0024] In use, as shown in Figure 8 , 9 the upper hanging ring 6 of the connector core 2 of the floating ball rope breakable connector 1 is connected with the floating ball rope 17 to connect the buoy 18, and the lower hook type breaker 9 suspends the submarine cable 19 rope 17, at this time, since the connector safety 5 is still in the state of being inserted into the shell safety insertion slot 12, the core limiting groove 8 is locked by the safety bolt 14, so that the position between the shell formed by the connector front shell 3 and the connector rear shell 4 and the connector core 2 is fixed and cannot slide up and down, so that the breaker blade 10 is blocked by the breaker protection shell 13, and the lower hook type breaker 9 cannot work, forming a lower hook state.

[0025] When it is needed to cut off the rope 17 of the submarine cable 19, only the connector safety 5 needs to be pulled out, as shown in Figure 10 , so that the shell and the connector core 2 are in a free state, at this time, once the upper hanging ring 6 is stressed, the hook type breaker 9 will be pulled out of the breaker protection shell 13, as shown in Figure 11 , 12 , and the breaker blade 10 contacts the rope 17 and finally cuts off the rope 17, completing the release of the submarine cable. At the same time, since the buoy 18 is still connected with the upper hanging ring 6 through the rope 17, the floating ball rope breakable connector 1 will float out of the water together with the buoy 18 for easy recovery.
