A device for clearing silt during submarine pipeline construction

Abstract

This utility model discloses a silt removal device for subsea pipeline construction, including a protective shell, a first gear, and a second gear. A toothed plate is provided on one side of the inner wall of the protective shell, and the first gear and the second gear are meshed together. This silt removal device for subsea pipeline construction, through the arrangement of the protective shell, first gear, second gear, toothed plate, drill bit, support rod, and stirring blade, allows the user to place the device into the subsea pipeline and move it downwards. Rotating the first gear drives the drill bit to disperse accumulated silt. The second gear meshes with both the first gear and the toothed plate, so that when the first gear rotates, the second gear rotates around the first gear as an axis, and simultaneously rotates itself. This causes the stirring blade to rotate around the first gear, preventing silt from being pushed into the protective shell, thus achieving the effect of simultaneously removing silt from the subsea pipeline and its internal components.

Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, and in particular to a device for clearing mud and sand during submarine pipeline construction. Background Technology

[0002] During the construction of submarine pipelines, the accumulation of silt and debris seriously affects construction efficiency and pipeline lifespan. Existing dredging technologies mostly rely on manual cleaning or simple machinery, which have drawbacks such as poor dredging effect, complex operation, and high cost. Therefore, there is an urgent need for a silt dredging device with a reasonable structure, high dredging efficiency, and adaptability to complex seabed environments to effectively solve problems such as long construction cycles and high maintenance costs, and improve the overall efficiency and safety of submarine pipeline construction.

[0003] Existing devices do not have the function of simultaneously cleaning the subsea pipeline and removing seawater from its interior. In areas with complex seabed topography, pipelines may be easily affected by silt and debris, and seawater may also enter the pipeline, increasing the difficulty of cleaning. The device cannot handle external silt and internal seawater at the same time, and the impact of water flow may cause the device to be unstable in position inside the pipeline, affecting the device's ability to collide with the inner wall of the subsea pipeline and reducing efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for clearing sediment during subsea pipeline construction includes a protective shell, a first gear, and a second gear. A toothed plate is provided on one side of the inner wall of the protective shell. The first gear and the second gear are meshed together. There are three second gears, each meshing with the toothed plate. A drill bit is fixedly connected to one side of the outer surface of the first gear, and the protective shell is rotatably connected to the drill bit. A support rod is fixedly connected to one side of the outer surface of the second gear, and a stirring blade is fixedly connected to one side of the outer surface of the support rod.

[0007] In order to achieve the purpose of clearing internal quicksand, as a mud and sand clearing device for submarine pipeline construction according to the present invention, a rotating rod is fixedly connected to one side of the outer surface of the first gear, a fan blade is fixedly connected to one side of the outer surface of the rotating rod, and the rotating rod penetrates one side of the inner wall of the protective shell and extends to one side of the outer surface of the protective shell.

[0008] In order to achieve the effect of power output, as a mud and sand dredging device for submarine pipeline construction of this utility model, a seawater-proof motor is fixedly installed on one side of the outer surface of the protective shell, and the output end of the seawater-proof motor is fixedly connected to the rotating rod.

[0009] In order to enable it to absorb seawater, as a silt removal device for submarine pipeline construction according to this utility model, a water suction head is provided on one side of the inner surface of the protective shell, and a cutting blade is rotatably connected to one side of the outer surface of the drill bit.

[0010] In order to provide support for rotation, as a silt removal device for submarine pipeline construction according to this utility model, a first support plate is fixedly connected to one side of the outer surface of the protective shell, a first connecting rod is rotatably connected to one side of the outer surface of the first support plate, and a second connecting rod is rotatably connected to one side of the outer surface of the first support plate.

The second gear meshes with the first gear and the toothed plate, so that when the first gear rotates, the second gear rotates around the first gear as an axis. At the same time, the second gear rotates itself, causing the stirring blade to rotate around the first gear, thus preventing the silt entering the protective shell from being pushed out.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown, a silt removal device for submarine pipeline construction includes a protective shell 1, a first gear 2 and a second gear 3. A toothed plate 4 is provided on one side of the inner wall of the protective shell 1. The first gear 2 and the second gear 3 are meshed together. There are three second gears 3, each meshing with the toothed plate 4. A drill bit 5 is fixedly connected to one side of the outer surface of the first gear 2. The protective shell 1 and the drill bit 5 are rotatably connected.

[0025] In this embodiment, a support rod 6 is fixedly connected to one side of the outer surface of the second gear 3, and a stirring blade 7 is fixedly connected to one side of the outer surface of the support rod 6.

[0026] In practical use, the user places the device into the subsea pipeline, moves it downwards, and rotates the first gear 2, which drives the drill bit 5 to rotate and disperse the accumulated silt. The second gear 3 meshes with the first gear 2 and the toothed plate 4 respectively, so that when the first gear 2 rotates, the second gear 3 rotates around the first gear 2 as an axis. At the same time, the second gear 3 rotates itself, so that when the stirring blade 7 rotates, it rotates around the first gear 2, which prevents the silt entering the protective shell 1 from being pushed out, thus achieving the effect of removing silt from the subsea pipeline at the same time as removing silt inside.

[0027] In this embodiment, a rotating rod 8 is fixedly connected to one side of the outer surface of the first gear 2, and a fan blade 9 is fixedly connected to one side of the outer surface of the rotating rod 8. The rotating rod 8 penetrates one side of the inner wall of the protective shell 1 and extends to one side of the outer surface of the protective shell 1.

[0028] In practical use, the rotation of the first gear 2 drives the rotation rod 8 to rotate, causing the fan blade 9 to stir the seawater entering the protective shell 1, thereby maintaining the smooth flow inside the device.

[0029] In this embodiment, a seawater-proof motor 10 is fixedly installed on one side of the outer surface of the protective shell 1, and the output end of the seawater-proof motor 10 is fixedly connected to the rotating rod 8.

[0030] In practical use, the seawater resistant motor 10 is the core power source of the device. It is specially designed for corrosion and water resistance and can work reliably in harsh underwater environments, driving the rotating rod 8 to rotate.

[0031] In this embodiment, a water suction head 11 is provided on one side of the inner surface of the protective shell 1, and a cutting blade 12 is rotatably connected to one side of the outer surface of the drill bit 5.

[0032] In practical use, the suction head 11 is installed on the inner surface of the protective shell 1 to absorb the seawater inside after stirring. When the drill bit 5 rotates, it drives the cutting blade 12 to open and rotate. The rotating cutting blade 12 cuts the mud and sand, so that the mud and sand are mixed with water, which facilitates the purpose of dredging.

[0033] In this embodiment, a first support plate 13 is fixedly connected to one side of the outer surface of the protective shell 1, a first connecting rod 14 is rotatably connected to one side of the outer surface of the first support plate 13, and a second connecting rod 15 is rotatably connected to one side of the outer surface of the first support plate 13.

[0034] In practical use, the rotation of the first link 14 and the second link 15 ensures that the device does not shift its position in the subsea pipeline, thus adapting to different subsea pipeline operation conditions.

[0035] In this embodiment, a cylinder 16 is rotatably connected to one side of the outer surface of the first connecting rod 14, and the output end of the cylinder 16 is rotatably connected to the second connecting rod 15.

[0036] In practical use, the cylinder 16 receives hydraulic or pneumatic pressure and drives its internal push rod to extend and retract.

[0037] In this embodiment, a wheel 17 is rotatably connected to one side of the inner wall of the first connecting rod 14. There are two wheels 17, and the wheels 17 are rotatably connected to the second connecting rod 15.

[0038] In practical use, the first link 14 and the second link 15 rotate inward, and the wheel 17 fits against the inner wall of the subsea pipeline, so that the transfer can be carried out without shifting its position inside the subsea pipeline, and at the same time, it can facilitate the movement of the device on the inner wall of the subsea pipeline.

[0039] Working principle: In use, the user places the device into the subsea pipeline channel and activates cylinder 16, causing the first connecting rod 14 and the second connecting rod 15 to rotate to both sides. When a certain position is reached, the output end of cylinder 16 retracts, causing the first connecting rod 14 and the second connecting rod 15 to rotate inward. The wheel 17 then fits against the inner wall of the subsea pipeline, ensuring that the device remains in place within the pipeline and facilitating its movement within the pipeline. The user places the device into the subsea pipeline and moves it downward, rotating the first gear 2, which drives the drill bit 5 to rotate and disperse accumulated debris. The aggregated silt is connected to the first gear 2 and the toothed plate 4 by the second gear 3, which meshes with the first gear 2 and the toothed plate 4 respectively. When the first gear 2 rotates, the second gear 3 rotates around the first gear 2 as an axis. At the same time, the second gear 3 rotates itself, so that when the stirring blade 7 rotates, it rotates around the first gear 2. This prevents the silt entering the protective shell 1 from being pushed out, thus achieving the purpose of removing silt from the subsea pipeline at the same time as removing silt from the inside. The suction head 11 is installed on the inner surface of the protective shell 1 to absorb the seawater inside after stirring, so as to facilitate the dredging. This completes the use of the device.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
