Problems solved by technology
[0002] The main role of power cables in the distribution network is to transmit large amounts of electricity to remote areas, and the operation of connecting cables deployed on the seabed is very complicated. When connecting operations at sea, good planning, high-quality personnel and equipment are required Handling and deployment of well-equipped installation vessels with long installation cycles, with connection operations typically lasting more than a few days
In the process of connection operation, it is inevitable to be affected by sea wind and waves, which may cause cable joint connection problems and lead to cable failure in the later stage; therefore, it is necessary to design the cable joint connection under the premise of considering the influence of wind and waves on the cable joint connection , and then simulate the deployment of the cable, and then test and verify the joint connection design after the simulation is completed. However, at present, the cable is simulated and deployed at the offshore site. Since the device itself needs to resist the influence of the external environment during the simulation at sea, the device itself high cost, which further leads to very high cost of offshore simulation

Embodiment
[0015] A construction site submarine cable simulation deployment device 100 of this embodiment is used to simulate the cable deployment process, including: a lifting part 1, a lifting rope 2, a lifting beam 3, a sling 4, a cable finger 5, a counterweight 6 and a horizontal frame 7.
[0016] The lifting part 1 is arranged on land.
[0017] In this embodiment, the lifting part is a lifting machine such as a crane that can be lifted and lowered.
[0018] A plurality of hoisting ropes 2 are connected to the bottom of the hoisting part 1, and a plurality of hoisting ropes 2 are connected transversely and symmetrically to both ends of the hoisting beam.
[0019] The lifting beam 3 is connected to the lower part of the lifting part 1 through the lifting rope 2 .
[0020] A plurality of slings 4 are fixed at both ends of the bottom of the lifting beam 3, and are used for hoisting cables 8, and the number of slings 4 at both ends of the bottom of the lifting beam 3 is the same, and t...
