Abstract
Description
Technical Field
[0001] The invention relates to the technical field of deviation correction devices, in particular to a deviation correction device used on the seabed. Background Art
[0002] For projects such as offshore wind power, it is generally necessary to install infrastructure such as equipment or related building components tens of meters below the seabed. Even in the field of offshore oil and gas, it is necessary to install related infrastructure at a depth of up to thousands of meters below the seabed. Due to the complex geological conditions of the seabed, and the fact that the installation operations of the infrastructure are generally controlled and operated on the sea surface (such as work ships), it is difficult to control the verticality of the installation of the infrastructure during the construction and installation process, that is, it is difficult to control the installation of the infrastructure to ensure that it will be more or less tilted in the vertical direction. In particular, when the installation site of the infrastructure is uneven or the geological conditions of the seabed soil are uneven, the installation of the infrastructure is more likely to fail to meet the installation requirements due to tilt. Therefore, it is necessary to correct the target (such as the infrastructure) so that when the target is deflected, it can be restored to a vertical state through correction. In summary, a correction device that can be used on the seabed to correct the target is needed. Summary of the invention

DETAILED DESCRIPTION
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figure 1-Figure 8As shown, this embodiment provides a deviation correction device for the seabed, including a support ring 30, and a sinking and penetration mechanism, a power mechanism and a deviation correction mechanism installed on the support ring 30. The support ring 30 can be a standard circle, an ellipse or an irregular closed ring, or a non-closed shape with a gap, at least a part of which is surrounded by a curve. It is only necessary to ensure that the power mechanism on the support ring 30 can move 360° (i.e., one circle) along the extension direction of the support ring 30, or close to being able to move 360°. For example, only one small gap is provided on the support ring 30, and the size of the gap is small, so that the power mechanism can cross the gap and move 360°, or although it cannot cross the gap, the power mechanism can reach both ends of the gap, so that moving along the support ring 30 can solve the movement of 360°, so that the power mechanism can reach one side in all directions relative to the central axis of the support ring 30.
[0017] The power mechanism is slidably mounted on the support ring 30 so as to be movable along the support ring 30 .
[0018] Exemplarily, the power mechanism is installed at the upper end of the support ring 30, so that the power mechanism is located at one side of the upper end of the support ring 30. That is, the power mechanism is installed at the upper end of the support ring 30 along the direction of gravity.
[0019] One end of the correction mechanism is connected to the power mechanism, and the other end is a free end, which is used to connect to the target object 80 that needs to be corrected, and under the force provided by the power mechanism, the target object 80 can be corrected, that is, the tilted target object 80 can be restored to a vertical state. For example, it is connected to the pile foundation that needs to be corrected. The free end can be sleeved on the target object 80 to achieve connection with the target object 80.
[0020] The sinking and penetrating device is installed at the lower end of the support ring 30, that is, installed at the end of the support ring 30 away from the power mechanism. The sinking and penetrating device is used to penetrate the deviation correction device into the seabed after the deviation correction device reaches the target position (that is, near the installation site), so that the deviation correction device can correct the target object 80 in a state of being stably installed on the seabed. When the deviation correction device penetrates the seabed, the end of the sinking and penetrating device away from the support ring 30 penetrates into the seabed, so that the deviation correction device penetrates the seabed.
[0021] Exemplarily, the sedimentation penetration device includes a suction bucket 10 and a drainage assembly 20. The suction bucket 10 is fixedly or detachably mounted on the lower end of the support ring 30. The drainage assembly 20 is mounted on the suction bucket 10. The drainage assembly 20 is used to pump out the seawater in the suction bucket 10 so that a pressure difference is formed inside and outside the suction bucket 10, that is, a water pressure difference is formed inside and outside, so that the suction bucket 10 can penetrate the seabed, that is, penetrate the seabed. The suction bucket 10 is a prior art, so it is not described here.
[0022] Exemplarily, the sinking device includes a plurality of sinking devices, each of which is disposed around the circumference of the support ring 30. For example, four sinking devices are disposed around the circumference of the support ring 30 and are distributed in a cross shape.
[0023] Exemplarily, the drainage component 20 includes a water pipe 21 and a drainage outlet 22. One end of the water pipe 21 is connected to the suction bucket 10, that is, connected to the inner cavity of the suction bucket 10, and the other end of the water pipe 21 is connected to the drainage outlet 22. The drainage component 20 discharges the seawater in the suction bucket 10 through the water pipe 21 and the drainage outlet 22 in sequence, thereby discharging the seawater from the inside of the suction bucket 10 to the outside of the bucket, so that a water pressure difference is formed inside and outside the suction bucket 10.
[0024] Exemplarily, the power mechanism includes a rail car 50, a first motor 40, a second motor 60, and a transmission assembly. The first motor 40 and the second motor 60 are both mounted on the rail car 50. The first motor 40 can be directly fixed or detachably mounted on the upper end of the rail car 50, and the second motor 60 can be directly fixed or detachably mounted on the side wall of the rail car 50. The output end (i.e., the rotor) of the first motor 40 is connected to the deviation correction mechanism to provide a pulling force to the deviation correction mechanism, so that the deviation correction mechanism can correct the target object 80 under the action of the pulling force.
[0025] The output end of the first motor 40 is connected to the rope wheel 41 to drive the rope wheel 41 to rotate. One end of the deviation correction mechanism is wound around the rope wheel 41, and the other end is a free end.
[0026] The rope 71 may be an electrical cable, an optical cable or other cables, or may be a rope or other linear structural member.
[0027] Exemplarily, the deviation correction mechanism includes a rope wheel 41, a rope 71 and a ring 70, one end of the rope 71 is wound around the rope wheel 41, and the other end is fixedly or detachably connected to the ring 70. The ring 70 is circular, oval or other annular. The ring 70 is used to be sleeved on the target object 80. Generally, when the target object 80 is a pile foundation, the pile foundation is generally a cylindrical structure, so the ring 70 is preferably circular.
[0028] Exemplarily, two rows of pulleys 53 are fixedly mounted at the lower end of the rail vehicle 50, the two rows of pulleys 53 are arranged in parallel and spaced apart, each row of pulleys 53 includes a plurality of pulleys 53, and the pulleys 53 in the same row are arranged in a straight line, the two rows of pulleys 53 are clamped and mounted on the support ring 30, and the pulleys 53 on the pulley 53 are in rolling contact with the support ring 30, so that the pulleys 53 can slide on the support ring 30. The second motor 60 is connected to the pulley 53 through the transmission assembly to drive the pulleys 53 on the pulley 53 to rotate, so that the rail vehicle 50 can be driven to slide along the support ring 30, so that the power mechanism can move on the support ring 30.
[0029] Exemplarily, the transmission assembly includes a driving gear 61, a transmission chain 52 and a driven gear 51, the output end of the second motor 60 is connected to the driving gear 61, so that the driving gear 61 can be driven to connect, one end of the transmission chain 52 is meshed with the driving gear 61 to achieve a transmission connection, the other end of the transmission chain 52 is meshed with the driven gear 51 to achieve a transmission wheel connection, and the driven gear 51 is transmission-connected with the pulley 53 group. The second motor 60 drives the pulley 53 of the pulley 53 group to rotate through the driving gear 61, the transmission chain 52 and the driven gear 51 in turn, so that the power mechanism can slidably move on the support ring 30.
[0030] The passive gear 51 and the pulley 53 group can drive the pulley 53 of the pulley 53 group to rotate through the existing transmission structure. Since the transmission structure is a prior art, it will not be described in detail here.
[0031] Exemplarily, the correction device also includes a bracket frame 31 and an annular sleeve 32. The bracket frame 31 is fixedly mounted on the inner wall of the annular through hole of the support ring 30 and is located in the annular through hole of the support ring 30. The bracket frame 31 is fixedly connected to the support ring 30 or is an integral structure. For example, the bracket frame 31 is welded to the support ring 30.
[0032] The bracket frame 31 is roughly rectangular, and the four vertices of the bracket frame 31 are strips with a short distance, so that the four vertices of the bracket frame 31 are in line contact or surface contact with the support ring 30, avoiding point contact, thereby avoiding the problem of loose connection.
[0033] The annular sleeve 32 is fixedly mounted on the inner wall of the annular through hole of the support frame 31 and is located in the annular through hole of the support frame 31 . The annular sleeve 32 is fixedly connected to the support frame 31 or is an integral structure. For example, the annular sleeve 32 is welded to the support frame 31 .
[0034] In actual use, when correction is needed, the correction device can be lowered from the working ship on the sea surface to a certain height from the seabed through a cable or a submersible, so as to reach the vicinity of the seabed. And the position of the correction device is fine-tuned so that the collar 70 is aligned with the tilted target 80. After the collar 70 is aligned with the target 80, the height of the correction device is further lowered so that the collar 70 is sleeved on the target 80. After the collar 70 is sleeved on the target 80, the correction device first penetrates a certain depth into the seabed under the action of its own gravity, that is, penetrates a certain depth into the seabed.
[0035] When the deviation correcting device falls into the seabed, the drainage component 20 is started, and the drainage component 20 discharges the seawater inside the suction bucket 10 (one end of the suction bucket 10 is provided with an opening to allow the seawater to enter) into the sea through the water pipe 21 and the drainage outlet 22. The suction bucket 10 further penetrates into the deeper seabed under the action of the internal and external water pressure difference, so that the deviation correcting device can be firmly fixed on the seabed.
[0036] After the deviation correction device is firmly fixed on the seabed, the second motor 60 is started, so that the power mechanism moves around the target object 80 on the support ring 30, and moves to the target position and is located on the side that is tilted away from the target object 80. For example, if the target object 80 tilts to the right, the power mechanism moves to the left side of the target object 80. When the power mechanism moves to the target position, the second motor 60 is turned off and the power mechanism stops moving. Then, the first motor 40 is started, and the output end of the first motor 40 rotates and is wound on the rope 71, thereby providing tension to the rope 71, so that the target object 80 is pulled by the tension, so that the target object 80 rotates toward the side where the power mechanism is located (that is, toward the direction away from the tilt), until the target object 80 returns to a vertical state, thereby completing the deviation correction.
[0037] In addition, the present invention can also realize an in-situ lateral force resistance test on the target object 80. In the process of the second motor 60 rotating to reel in the rope 71, the relationship between the lateral load and displacement of the target object 80 can be calculated through the torque and the number of rotations of the first motor 40, and a load-displacement curve can be obtained, so that the lateral force resistance data of the target object 80 can be obtained according to the load-displacement curve, and the in-situ lateral force resistance test can be completed.
[0038] Among them, the relationship between the lateral load and displacement of the target object 80 is calculated by the torque and the number of rotations of the first motor 40. It can be calculated according to the existing technology. It only needs to measure the torque and the number of rotations to convert and calculate the relationship between the lateral load and the displacement. The general conversion formula is as follows: lateral load = torque / radius of the rope wheel 41, displacement = number of rotations * pi π * diameter of the rope wheel 41. Since it is an existing technology, its specific calculation process is not repeated here.
[0039] Among them, the support frame 31 and the annular sleeve 32 play the role of providing a reaction force to the target object 80. Under the action of tension, the target object 80 acts on the annular sleeve 32, and the annular sleeve 32 provides a reaction force to the target object 80, so that the target object 80 can only rotate but is prohibited from moving, so that the target object 80 can achieve the lateral force resistance test under in-situ conditions.
[0040] After use, turn off the first motor 40, start the drainage assembly 20 again and rotate it in the opposite direction, inject seawater into the suction bucket, increase the water pressure inside the suction bucket 10, and thereby pull the suction bucket 10 out of the seabed under the action of the internal and external water pressure difference, so that the entire correction device is detached from the seabed, so that the correction device can be recovered to the sea surface.
[0041] The present invention can penetrate the deviation correction device into the seabed or pull it out from the seabed to achieve ascending recovery through the sinking and penetration device. The sinking and penetration device can reduce the squeezing effect on the surrounding soil where the deviation correction device is located to the greatest extent through the suction bucket 10. The squeezing effect is not large, and the impact on the surrounding environment is not large. The deviation correction device can correct the tilted target 80 and restore it to vertical without causing destructive effects on the target 80. Through multiple sinking and penetration devices, and the cooperation with the support ring 30, the bracket frame 31 and the annular sleeve 32, the entire deviation correction device can withstand a large pulling force, thereby achieving a greater deviation correction ability, and can be moved to different positions through a power mechanism, so that the target 80 tilted in different directions can be corrected. In addition, the deviation correction device can also carry out lateral force resistance tests under in-situ conditions, and has a wider range of applications.
[0042] The embodiment disclosed in this specification is only an example of a unilateral feature of the present invention, and the protection scope of the present invention is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of the present invention. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
