[0002] During the construction of pile foundations above water, it is necessary to use an installation platform on the underwater mud bed to assist in positioning the pile pipe. During the actual construction process, it is found that due to the complex hydrological environment underwater, the contact between the installation platform submerged underwater and the mud surface cannot be in a fitted state, so the installation platform will be in a tilted state.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-8 The present invention provides a technical solution: an underwater leveler:

[0036] Embodiment 1: Refer to the attached manual Figure 1 , Attachment Figure 2 , Attachment Figure 3 ; It includes a bracket 1, on which a hanger and a pile holder (not shown) and other structures are installed. A support mechanism is arranged outside the bracket 1, and the support mechanism includes a lifting rod 2. The lifting rod 2 is made of an existing hydraulic cylinder and is connected to an external control circuit. The output end of the lifting rod 2 is fixedly connected to a connecting piece 3, and the connecting piece 3 is arranged around the bracket 1 for balanced support. The outer surface of the connecting piece 3 is fixedly connected to the outer surface of the bracket 1. An anti-sinking plate 4 is arranged outside the lifting rod 2, and a sliding sleeve 5 is arranged outside the anti-sinking plate 4. The inner sliding sleeve 5 It is dynamically connected with a piston plate 6, and a sliding rod 8 is fixedly connected to the outer surface of the piston plate 6. There are multiple groups of piston plates 6 and sliding rods 8 arranged at equal angles around the periphery of the lifting rod 2 to provide balanced support and facilitate leveling. One end of the sliding rod 8 is slidably connected to the body of the sliding sleeve 5 and extends to the outside of the sliding sleeve 5. One end of the sliding rod 8 and the sliding sleeve 5 are fixedly connected with a universal joint 9. The universal joint 9 can facilitate the anti-sinking plate 4 to rotate at multiple angles, thereby facilitating adaptation to different underwater mud bed environments. One end of the universal joint 9 on both sides is fixedly connected to the lifting rod 2 and the outer surface of the anti-sinking plate 4, respectively.

[0037] The outer surface of the anti-sinking plate 4 is fixedly connected to the base 10, and the outer surface of the base 10 is provided with a ball groove 11. The inside of the ball groove 11 is movably connected with a round ball 12. The round ball 12 is made of pressure-resistant, wear-resistant and corrosion-resistant materials, and the size of the part exposed on the surface of the base 10 is smaller than its own radius, which facilitates rotation and improves the stability of the connection. The outer surface of the round ball 12 is fixedly connected to the outer surface of the lifting rod 2.

[0038] By setting up a supporting mechanism, the lifting rod 2 is used for extension and retraction for support, and the balance is adjusted by sliding the piston plate 6 and the slide rod 8, thereby reducing wear and extending the service life. At the same time, the movement of the ball 12 in the ball groove 11 allows the anti-sinking plate 4 to be rotated and adjusted to adapt to the underwater mud bed, thereby improving the balancing effect on the bracket 1.

[0039] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 3 , Attachment Figure 4 ; A pressure control assembly 7 is provided on the outside of the piston plate 6. The pressure control assembly 7 includes a filter plate 71. The filter plate 71 plays a role of limiting abutment and also facilitates the flow of air so as to drive the piston plate 6 to move. The outer surface of the filter plate 71 is fixedly connected to the inside of the sleeve 5. A one-way valve 74 is provided on the outside of the filter plate 71. The one-way valve 74 allows high-pressure gas to flow unidirectionally to the inside of the sleeve 5. The inside of the one-way valve 74 is connected through and communicated with the inside of the sleeve 5. The inside of the one-way valve 74 is connected with a pressure relief valve 75. The pressure relief valve 75 adopts the existing pressure valve support and plays a one-way flow role. When the internal pressure value of the sleeve 5 is higher than the predetermined value, the high-pressure gas is discharged from the inside of the sleeve 5 through the pressure relief valve 75. The inside of the pressure relief valve 75 is connected with the inside of the sleeve 5.

[0040] One end of the pressure relief valve 75 and the one-way valve 74 are both connected to a spring tube 76, which facilitates the movement of the sliding sleeve 5 by telescoping. The outer surface of the anti-sinking plate 4 is fixedly connected to an air box 77, which can store and release high-pressure gas. One end of the spring tube 76 on one side is connected to the interior of the air box 77, and an air pump 78 is provided inside the air box 77. The air pump 78 is electrically connected to an external control circuit, and an electromagnetic valve is provided on its input end to control the gas pumping out. The output end of the air pump 78 is fixedly connected to the body of the air box 77 and extends to the outside of the air box 77. The output end of the air pump 78 is connected to one end of the spring tube 76 on the other side.

[0041] By setting up a pressure control component 7 and utilizing the air box 77 to release or store high-pressure gas, it is convenient to replenish or release air according to the change of space after the piston plate 6 moves, so that the piston plate 6 can obtain a stable pressure, thereby stably supporting the bracket 1 and facilitating timely leveling so that the bracket 1 always maintains balance.

[0042] Embodiment 3: Based on Embodiment 2, refer to the attached Figure 3 , Attachment Figure 5 A limiting unit 72 is arranged on the outside of the filter plate 71, and the limiting unit 72 includes a limiting plate 721. The limiting plate 721 plays a limiting abutment role and can limit the movement range of the piston plate 6 when the mud bed changes to avoid damage to the opposite side piston plate 6 due to excessive force. The outer surface of the limiting plate 721 is movably connected with the inside of the sliding sleeve 5 and the outer surface of the piston plate 6 respectively. The body of the limiting plate 721 is provided with a through sliding hole 722. The aperture of the sliding hole 722 is adapted to the outer diameter of the sliding rod 8, and the inside of the sliding hole 722 is movably connected with the outer surface of the sliding rod 8.

[0043] The outer surface of the limit plate 721 is fixedly connected to a screw rod 723, the outer surface of the screw rod 723 is threadedly connected to a screw sleeve 724, the outer surface of the screw sleeve 724 is rotatably connected to the interior of the sliding sleeve 5, the outer surface of the screw sleeve 724 is fixedly connected to a drive motor 725, the drive motor 725 is made of a servo motor and is electrically connected to an external control circuit, and the outer surface of the drive motor 725 is fixedly connected to the interior of the sliding sleeve 5.

[0044] By setting the limit unit 72, after the position of the piston plate 6 is adjusted, the driving motor 725 is connected through the screw rod 723 and the screw sleeve 724, so that the screw rod 723 drives the limit plate 721 to move axially along the slide rod 8 to adapt the position, thereby avoiding excessive movement of the piston plate 6 on one side, resulting in excessive force on the piston plate 6 on the other side and reducing the service life.

[0045] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 6 , Attachment Figure 7 The filter plate 71 is provided with a leveling unit 73 on the outside. The leveling unit 73 is provided with four groups so that when tilting occurs, it can monitor and level all directions. It can also be arranged on the anti-sinking plate 4. The leveling unit 73 includes a support rod 731. One end of the support rod 731 is fixedly connected to the outer surface of the lifting rod 2. The outer surface of the support rod 731 is rotatably connected with a rotating sleeve 732. Both sides of the outer surface of the rotating sleeve 732 are movably connected with fixed rings 733. The fixed rings 733 play a clamping and limiting role. The annular holes of the fixed rings 733 on both sides are fixedly connected to the outer surface of the support rod 731. The outside of the rotating sleeve 732 is fixedly connected with a vertical bar 734. The vertical bar 734 plays a vertical leveling role and is made of insulating material. The body of the vertical bar 734 is fixedly connected with a fixed ball 736. The fixed ball 736 is made of a material with large mass to lower the center of gravity of the vertical bar 734 so that it remains vertically downward and is hollow inside.

[0046] The outer surface of the support rod 731 is penetrated and fixedly connected with a shell 737, and the shell 737 is made of pressure-resistant, corrosion-resistant, wear-resistant and insulating materials. The inside of the shell 737 is fixedly connected with an insulating block 738, and the outer surface of the insulating block 738 is movably connected with a conductive block 739, and the outer surface of the conductive block 739 is fixedly connected to the outer surface of the vertical bar 734. Both sides of the outer surface of the insulating block 738 are fixedly connected with conductive strips 7310, and the outer surfaces of the conductive strips 7310 on both sides are movably connected to the outer surface of the conductive block 739 through rotation. The conductive block 739 and the conductive strip 7310 are both made of wear-resistant conductive materials, and the conductive strip 7310 is electrically connected to the external control circuit.

[0047] By setting up the leveling unit 73 and utilizing the gravity of the solid ball 736, the vertical bar 734 can always remain vertically downward, and the shell 737 can be used to drive the conductive bar 7310 to move. The contact between the conductive bar 7310 and the conductive block 739 allows the circuit to be connected to form a leveling signal, so as to control the movement of the piston plate 6 and make it move to adapt to the mud bed through the rotation of the anti-sinking plate 4.

[0048] Embodiment 5: Based on Embodiment 4, refer to the attached Figure 6 , Attachment Figure 8 A monitoring module 735 is arranged on the outside of the vertical bar 734, and the monitoring module 735 includes a slide plate 7351. The outer surface of the slide plate 7351 is slidably connected to the inside of the shell 737. The outer surface of the slide plate 7351 is fixedly connected to a displacement sensor 7352. The displacement sensor 7352 is electrically connected to an external control circuit. The position of the slide plate 7351 is monitored to reconfirm the signal of the tilt. The outer surface of the displacement sensor 7352 is fixedly connected to the inside of the shell 737. The outer surface of the slide plate 7351 is fixedly connected to a magnetic column 7353. The magnetic column 7353 is made of magnetic material. An electromagnet 7354 is arranged on the outside of the magnetic column 7353. The electromagnet 7354 is electrically connected to the conductive block 739. The slide plate 7351 can be driven to move through magnetic adsorption with the magnetic column 7353. The outer surface of the electromagnet 7354 is fixedly connected to the inside of the solid ball 736.

[0049] The body of the slide plate 7351 is movably connected with a spiral rod 7355, which can be rotated by spirally abutting the slide plate 7351, and also supports and guides the movement of the slide plate 7351. One end of the spiral rod 7355 is fixedly connected with a pin rod 7356, and one end of the pin rod 7356 is embedded and rotatably connected with the interior of the shell 737. A torsion spring 7357 is sleeved on the outside of the pin rod 7356. The torsion spring 7357 can facilitate the reset of the slide plate 7351 by rebounding, and the two ends of the torsion spring 7357 are respectively fixedly connected to the outer surface of the pin rod 7356 and the interior of the shell 737.

[0050] By setting up the monitoring module 735, when the monitoring circuit is connected, the electromagnet 7354 is energized to generate magnetism to attract the magnetic column 7353, so that the slide plate 7351 drives the output end of the displacement sensor 7352 to move, thereby detecting the tilt problem through the change in position, so as to control the movement of the piston plate 6 for adjustment.

[0051] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0052] During operation, first, the bracket 1 is placed in the water, and then the output end of the lifting rod 2 is extended, so that the anti-sinking plate 4 moves underwater to fit the mud bed, and during the fitting process, the ball 12 and the ball groove 11 are connected to rotate to adjust the angle and position. At the same time, during the adjustment process, the piston plate 6 and the slide rod 8 of each group follow the synchronous movement. Then, when the position is determined, the air pump 78 pumps the high-pressure gas in the air box 77 into the inside of the sliding sleeve 5 through the spring tube 76 on one side and the one-way valve 74. The high-pressure gas flows inside the sliding sleeve 5 through the filter holes of the filter plate 71 to support and fix the piston plate 6, thereby supporting the lifting rod 2 and the bracket 1.

[0053] When the shape of the mud bed surface changes, the anti-sinking plate 4 cannot stably support the bracket 1, causing the bracket 1 and the lifting rod 2 to tilt, and then the support rod 731 drives the shell 737 to tilt, and at the same time makes the conductive strip 7310 and the insulating block 738 follow the movement, so that the conductive block 739 contacts the conductive strip 7310, and the conductive strip 7310 on which side the conductive block 739 contacts is tilted to the opposite side, and at the same time, the electromagnet 7354 is energized to generate magnetism, and it attracts the magnetic column 7353 through magnetic force, so that the slide plate 7351 follows the sliding, and the slide plate 7351 is spirally abutted, so that the spiral rod 7355 drives the pin rod 7356 to rotate, so that the torsion spring 7357 is compressed, so that the slide plate 7351 is reset by rebounding, and at the same time, the movement of the slide plate 7351 drives the output end of the displacement sensor 7352 to move, so that the tilt is confirmed again by monitoring the position change;

[0054] When the tilt signal and the direction signal are received, the air pump 78 inside the air box 77 starts to work and pumps air into the inside of the sleeve 5. By pushing the piston plate 6 to move, the slide rod 8 follows the movement to adjust the position of the anti-sinking plate 4 so that it fits the mud bed again. At the same time, if the air pressure inside the sleeve 5 is too high, it is discharged into the air box 77 for storage through the pressure relief valve 75 and the spring tube 76 on the other side. Then, after the position of all piston plates 6 is determined again, the volume change inside the sleeve 5 and the position change of the piston plate 6 can be obtained according to the amount of pores inside the air box 77 and the amount of air inside the sleeve 5. Then, the driving motor 725 is connected through the screw rod 723 and the screw sleeve 724, so that the screw rod 723 drives the limit plate 721 to move again to adapt the position, thereby limiting the movement of the piston plate 6 through the limit plate 721, so as to reduce the problem of increased force on the opposite piston plate 6 due to the increase in displacement, thereby reducing its service life.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
