Description

Technical Field

[0001] The utility model belongs to the technical field related to submarine cable construction, and specifically relates to a surge-resistant cable-passing device for submarine cable construction. Background Art

[0002] The development of submarine cable laying technology can be traced back to the 19th century, when people began to try to lay cables on the seabed to achieve long-distance communications. However, due to technical limitations, early submarine cable laying work faced many difficulties, such as the weight of the cable, the complexity of the seabed terrain, and severe weather conditions. With the advancement of science and technology, especially the development of materials science, mechanical engineering, and electronic engineering, submarine cable laying technology has been significantly improved. Now, we are able to lay submarine cables in deep-sea environments and ensure the stability and reliability of submarine cables.

[0003] However, during the construction of existing submarine cables, sea surges will affect the stability of the equipment, causing sudden changes in the tension of the submarine cables during construction, damaging the submarine cables, and causing the actual route of the submarine cable construction to deviate from the designed position, affecting the precision and accuracy of the construction and endangering the construction safety and quality. Utility Model Content

[0004] The purpose of the utility model is to provide a surge-resistant cable-passing device for submarine cable construction, so as to solve the problem in the above-mentioned background technology that during the construction of the existing submarine cable, the sea surges will affect the stability of the equipment, resulting in a sudden change in the tension of the submarine cable during the construction process, damaging the submarine cable, and causing the actual route of the submarine cable construction to deviate from the designed position, affecting the precision and accuracy of the construction, and endangering the construction safety and quality.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a submarine cable construction anti-surge cable passing device, comprising a submarine cable ship;

[0006] A control chamber is provided at the front position inside the submarine cable ship, an external bracket is provided at the rear end position of the submarine cable ship, and the submarine cable construction anti-surge cable passing device is powered by an internal power supply;

[0007] A wire wheel is arranged at the middle position inside the submarine cable ship, a positioning piece is arranged at the right side of the wire wheel, and a cable guide rod is arranged at the bottom position of the positioning piece.

[0008] Preferably, a counterweight is provided at the right side of the positioning member, a limit rod is provided in an array at the outer side of the counterweight, four limit rods are provided in the array, and a telescopic line is provided at the inner position of the wire wheel, and the telescopic line passes through the counterweight and the outer bracket and is connected and fixed to the bottom cable guide rod.

[0009] Preferably, the cable guide rod is rotatably connected to the positioning member, a limiting groove is provided at a middle position inside the cable guide rod, a submarine cable is provided at a position inside the limiting groove, and a submarine cable plow is provided at a terminal position of the cable guide rod.

[0010] Preferably, the submarine cable plough is provided with supporting legs at the left and right sides respectively, a supporting frame is provided at the top of the submarine cable plough, a sand removal component is provided at the front side of the supporting frame, a sand removal port is provided at the top of the sand removal component, a spraying component is provided at the bottom of the sand removal component, and connecting pipes are provided in an array at the sides of the spraying component and the sand removal component.

[0011] Preferably, a sand filling plow is provided at the rear side of the submarine cable plow, and plowboards are provided at the left and right sides of the sand filling plow respectively.

[0012] Preferably, fixing rods are arranged in an array at the middle position inside the moldboard, the front side of the moldboard is folded outward, and the fixing rods are welded to the moldboard.

[0013] Preferably, the submarine cable ship is made of steel material, and anti-rust paint is sprayed on the outer side of the submarine cable ship.

[0014] Compared with the prior art, the utility model provides a cable-passing device for anti-surge in submarine cable construction, which has the following beneficial effects:

[0015] 1. Through the setting of positioning parts, counterweights, limit rods, wire wheels, telescopic wires, cable guides, limit grooves, submarine cable plows, sand removal components, jet flushing components and connecting pipes, the existence of counterweights enables the telescopic wires to maintain appropriate tension during the cable laying process, thereby ensuring that the cable guides can be smoothly lowered to the seabed. The size and position of the counterweights need to be accurately calculated and adjusted to provide sufficient force to overcome the gravity and other resistances of the submarine cable without affecting the laying of the submarine cable. The limit rods can limit the movement of the counterweights and prevent the counterweights from being dislocated. The ship releases the cable through the fairlead. The limit groove in the fairlead can prevent the internal submarine cable from being dislocated. The bottom submarine cable plow jet assembly hydraulically jets through the soil to form a cable trench. The internal sand discharge assembly discharges the suspended sea sand from the top sand discharge port through the connecting pipe, and then the submarine cable is placed into the cable trench. The cable release process is accurately controlled to reduce the risk of damage to the submarine cable. The counterweight and limit mechanism improve the stability and safety of the system. The sand discharge assembly effectively cleans the seabed and creates good conditions for laying submarine cables. The overall operation is efficient, which shortens the laying time of submarine cables and reduces costs.

[0016] 2. Through the setting of sand filling plow, plowboard and fixed rod, this design allows the plowboard to fold forward during the laying of submarine cable, so as to more effectively gather the outer sea sand inward to form a sand embankment to protect the submarine cable. This can reduce the possibility of external interference to the submarine cable and improve the protection effect of the submarine cable. When the submarine cable enters the opened seabed, the plowboard gathers the outer sea sand inward and fills the submarine cable with the sea sand to form a protective layer. This self-filling sand method not only saves additional material costs, but also has less impact on the seabed ecology due to the use of materials from the natural environment. The fixed rods arranged in an array in the middle position inside the plowboard can ensure the smooth operation of the plowboards on the left and right sides. The fixed rods play a supporting and stabilizing role to ensure that the plowboard will not deviate or flip during operation, thereby ensuring the accuracy and safety of submarine cable laying.
