Abstract
The utility model discloses a kind of submarine cable scour protection devices; including the outer layer baffle in herringbone setting and the internal layer baffle being arranged in herringbone; the top of internal layer baffle is connect with the top of outer layer baffle; and the angle of internal layer baffle is less than the angle of outer layer baffle; the first grid hole of matrix distribution is equipped on two baffles of outer layer baffle, the upper half of two baffles of internal layer baffle is equipped with one and arranges the 2nd grid hole.The utility model can improve the velocity flow profile above submarine cable, and promote silting, avoid submarine cable from causing seabed scouring because surrounding seawater flow velocity is excessive, so that submarine cable is safer.
Description
Technical field
The utility model relates to a kind of submarine cable scour protection device, flow velocity near submarine cable can be improved and promoted
Into sediment siltation.
Background technique
It is well known that submarine cable coating, which will receive, to be washed away when ocean current flow velocity is too fast near the submarine cable of phytal zone, cause
So that submarine cable is exposed to seabed, or even hanging, brings great risk to the normal operation of submarine cable.
Utility model content
In view of the above problems, the utility model provides a kind of submarine cable scour protection device, seabed electricity can be reduced
Flow velocity near cable routing, and sediment siltation can be promoted.
To achieve the above object, the technical solution of the utility model is:
A kind of submarine cable scour protection device, including the outer layer baffle in herringbone setting and in herringbone setting
The top of internal layer baffle, internal layer baffle is connect with the top of outer layer baffle, and the angle of internal layer baffle is less than the folder of outer layer baffle
Angle is equipped with the first grid hole of matrix distribution, the upper half of two baffles of internal layer baffle on two baffles of outer layer baffle
It is equipped with one and arranges the 2nd grid hole.
The submarine cable scour protection device of the utility model can cut down sea using dual-layered baffle plate structure with hierarchical
The ocean current of bottom cable routing top, can be placed directly in right above submarine cable routing, and will not be formed and be oppressed to submarine cable.
Further, device falls into sea bed because of self gravity in order to prevent, and the bottom four corners of the outer layer baffle are all provided with
There is support plate.
Further, the outer layer baffle and internal layer baffle are process using steel, and surface has antifouling paint
Layer, can effectively prevent the corrosion of seawater.
Compared with prior art, the utility model has the beneficial effects that:
The utility model can improve the velocity flow profile above submarine cable, and promote silting, avoid submarine cable
Cause seabed scouring because surrounding seawater flow velocity is excessive, so that submarine cable is safer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model submarine cable scour protection device；
Description of symbols: 1- outer layer baffle；2- internal layer baffle；The first grid hole of 3-；The second grid hole of 4-；5- support is flat
Plate.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
As shown in Figure 1, a kind of submarine cable scour protection device, using dual-layered baffle plate structure, main includes in herringbone
The outer layer baffle 1 of shape setting and the internal layer baffle 2 being arranged in herringbone.
It is fixed together by welding at the top of two baffles of outer layer baffle 1 and two baffles of internal layer baffle 2, internal layer
Baffle reserves certain adjustment of displacement space under the premise of meeting submarine cable size, and the open angle of outer layer baffle 1 is big
In the open angle of internal layer baffle 2.
Two permeable designs of baffle use side grid type of outer layer baffle 1, the first grid hole 3 is distributed in matrix thereon, this
In embodiment, the arrangement of the first grid hole 3 is 2*6.Also use side's grid type is permeable sets for two baffles of internal layer baffle 2
Meter, the difference with outer layer baffle 1 are that only the 2nd grid hole 4 is arranged in half portion setting on it one to two baffles of internal layer baffle 2.
Whole device falls into sea bed because of self gravity in order to prevent, welds a support plate 5 in the bottom four corners of outer layer baffle 1.
Meanwhile in order to improve Corrosion Protection, outer layer baffle 1 and internal layer baffle 2 are all made of steel and are process, and outer surface is prevented
Rotten paint processing.
In use, the present apparatus is directly buckled in above submarine cable, easy for installation, can either play reduces seabed electricity
Cable flow velocity, and can play the role of promoting sediment siltation.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
