Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a flushing and burying device for laying submarine cables comprises an upper support 1, a connecting support 2 is fixedly installed at the top end of the upper support 1, side baffles 3 are respectively pin-connected to two sides of the bottom end of the upper support 1 through pin shafts, the upper support 1 and the side baffles 3 are in transmission connection through hydraulic pistons 4, a fixed support 5 is fixedly installed in the middle of an inner cavity of the upper support 1, a high-pressure water pump 6 is in threaded connection with one side of the top end of the fixed support 5, one end of the high-pressure water pump 6 is communicated with a sealing connecting plate 8 fixedly installed with the side baffles 3 through a connecting pipeline 7, the other end of the high-pressure water pump 6 penetrates through and extends to the top of the upper support 1, a sealing connecting plate 8 is in threaded connection with the other side of the top end of the fixed support 5, one end of the sealing connecting plate 8 is communicated with the inner cavity of the hydraulic pistons 4, a sealing cabin plate 10 is arranged in the middle of the inner cavity of the upper support 1 and below the fixed support 5, the cable through groove 11 has been seted up at the middle part on 1 top of upper support, and the top of 1 inner chamber of upper support and the below round pin that is located the cable through groove 11 have leading wheel 12, and the bottom of 1 inner chamber of upper support and the right below round pin that is located leading wheel 12 have pre-buried guide pulley 13.

The connecting support 2 is used for installing a driving device in the flushing and burying equipment to drive the flushing and burying equipment to move forwards or adjust the advancing direction of the flushing and burying equipment at the same time by the specified depth in the submerged sea mud.

Wherein, to the setting of fixed bolster 5, can form an inclosed space in the inner chamber of upper support 1 to protect high pressure water pump 6 and hydraulic power unit 9, prevent that the sea water from being in the corrosion damage that the sea water caused in the sea water for a long time to high pressure water pump 6 and hydraulic power unit 9, the effectual life who prolongs high pressure water pump 6 or hydraulic power unit 9.

In this technical scheme, the top of upper support 1 is equipped with the toper structure, and the opening angle on 1 top of upper support is equipped with 60.

Wherein, to upper support 1 and its contained angle setting, can effectually reduce this towards bury the pressure of equipment when advancing in the sea mud for should dashing bury to have had stronger crushing resistance, have good stability and the reliability is higher.

In the technical scheme, the side baffle 3 and the left end of the upper layer bracket 1 are combined to form a quadrangular pyramid structure.

Wherein, to the setting that

side shield

3 and 1 left end of upper strata support formed the quadrangular pyramid structure, the effectual resistance that has reduced when should dashing to bury equipment and advance in the sea mud, further improvement should dash and bury equipment flexibility when the activity in the sea mud, and then reduced the power output who is located the drive arrangement at 2 tops of linking bridge.

In the technical scheme, the sealing connecting plate 8 is made of flexible rubber, the sealing connecting plate 8 always penetrates and extends between the two groups of side baffles 3, and the opening and closing angle between the two groups of sealing connecting plates 8 ranges from 60 degrees to 75 degrees.

Wherein, to sealed even setting of board 8, make water pressure can spout along the clearance between two sets of side shields 3 when starting high pressure water pump 6, thereby the sea mud that will be located this equipment bottom breaks away from both sides and forms one pre-buried irrigation canals and ditches, utilize the setting of two sets of side shields 3 simultaneously, can effectually block the sea mud that is broken away, make the irrigation canals and ditches that form can keep one end time, so that utilize leading wheel 12 and pre-buried guide pulley 13 to pull the cable to the irrigation canals and ditches in, later under the flow of sea mud, the cable that will be located in the irrigation canals and ditches that can be automatic buries.

The arrangement of the opening angle between the two groups of side baffles 3 is convenient for the cables on the guide wheel 12 and the embedded guide wheel 13 to be put down, so that the phenomenon of blockage caused by overlarge diameter of the cables is avoided.

The cable laid on the seabed can be pulled to the depth of embedding in the sea mud by the guide wheel 12 and the embedded guide wheel 13 in a certain radian, so that the cable cannot be damaged due to transition bending, and meanwhile, the scraping damage to the surface of the cable is reduced by adopting a sliding friction mode when the cable is pulled.

The use method and the working principle of the embodiment are as follows:

firstly, a driving device is installed at the top of a connecting support 2, then the driving device is started to lower the buried equipment to the surface of the sea floor, then one end of a laid cable passes through a guide wheel 12 and a pre-buried guide wheel 13 from a cable through groove 11 on an upper support 1 and extends to the tail part of the buried equipment, then the driving device is started again to drive the buried equipment to sink to a specified depth in sea mud, then a high-pressure water pump 6 and a hydraulic pump station 9 are started, seawater passes through a connecting pipeline 7 in a high-pressure mode by the high-pressure water pump 6 and is sprayed out from between two groups of side baffles 3 (wherein the direction of an arrow is the direction of high-pressure water flow), the sea mud at the bottom of the buried equipment is dispersed along the outside of the side baffles 3, and simultaneously under the hydraulic transmission action of the hydraulic pump station 9 and a hydraulic piston 4, the two groups of side baffles 3 are slowly spread to prevent the dispersed sea mud from being re-gathered, and then form a stable ditch at the bottom of the buried equipment, then under the effect of drive arrangement, drive the buried equipment of this dashing to bury and put and promote forward along the cable laid, and then pull the cable that is located the seabed surface to the seabed appointed degree of depth, and the ditch that forms loses the stopping of side shield 3, because its own has certain mobility, the flow of sea water is in simultaneously, make sea mud remove gradually and fill the ditch, and then bury the cable that is located the ditch bottom in the sea mud.
