However, since the sea depth reaches several tens of meters, an underwater guide frame is required to assist the proper burying of the pile leg, but there are many uneven sludge on the sea floor, which requires the underwater guide frame to have a leveling function. When piling, the frame body receives the impact stress component force of the pile hammer, the current anti-sinking plate is difficult to level, and when receiving the impact stress, the frame body forms a sealing layer with the silt, so that the frame body is difficult to lift.

Detailed Description
Specific embodiments of the present invention will be described in more detail below with reference to the drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention.
As shown in fig. 1, fig. 2 and fig. 3, the underwater guide frame with high structural strength provided by the embodiment of the invention comprises a frame body 1, four guide cylinders 2 vertically arranged on the frame body 1 and an anti-sinking mechanism 3 arranged at the middle position of the bottom of the frame body 1, wherein the anti-sinking mechanism 3 is connected with the frame body 1 through a leveling mechanism, the anti-sinking mechanism 3 comprises an anti-sinking plate 4, a through hole 5 is formed in the middle part of the anti-sinking plate 4 in a penetrating manner, a plurality of unidirectional circulation assemblies 6 which circulate unidirectionally from top to bottom are distributed in the anti-sinking plate 4, and the anti-sinking plate 4 is connected with the leveling mechanism.
Specifically, as shown in fig. 4, the unidirectional flow assembly 6 includes a limit cap 7, a spring base 8, a baffle 9, and a spring 10. The spring base 8 is in a cylinder shape, the top end is open, the bottom end is sealed, and drain holes 11 are uniformly distributed on the circumferential side wall of the spring base 8. The spring 10 is vertically arranged in the spring mount 8. The middle part of the limiting cover 7 is provided with a water flow hole 12 in a penetrating way, and the limiting cover 7 is connected to the open end of the top of the spring base 8. The baffle plate 9 is movably arranged in the spring base 8, the baffle plate 9 is arranged between the top of the spring 10 and the bottom of the limit cover 7, and the upper surface of the baffle plate 9 is movably attached to the bottom surface of the limit cover 7 so as to seal the water flow hole 12.
When the underwater guide frame is lifted upwards, seawater and silt flow in from the water flow holes 12, the spring 10 is compressed downwards through the baffle plate 9, after the spring 10 is compressed, the baffle plate 9 is separated from contact with the bottom surface of the limit cover 7, and moves downwards along the axial direction of the spring base 8, at the moment, the drain holes 11 are communicated with the water flow holes 12, and the seawater and the silt can flow from the upper surface of the anti-sinking plate 4 to the lower surface.
Annular limiting bosses 13 are concentrically arranged on the inner wall of the spring base 8, the limiting bosses 13 are arranged at the bottom of the drain hole 11, and the inner diameter size of the limiting bosses 13 is smaller than that of the baffle 9. The spring 10 vertically penetrates into the limit boss 13. The limiting boss 13 is used to limit the downward movement travel of the shutter 9.
Further, as shown in fig. 2, a plurality of drainage convex blocks 14 are distributed on the upper surface of the anti-sinking plate 4, and the drainage convex blocks 14 are spherical crowns.

The distribution of the different sized drainage bumps 14 is related to the distribution of the unidirectional flow components 6 on the anti-settling plate. Specifically, a large drainage bump 14 is adopted at the dense center of the unidirectional flow assembly 6 to assist water and sediment to flow into the nearby unidirectional flow assembly 6 better; a relatively small drainage bump 14 is used at the peripheral edge of the anti-settling plate 4.
Because the surface of the drainage convex block 14 presents a smooth spherical crown shape, water and sediment on the surface of the drainage convex block 14 can slide down to the periphery along the surface of the drainage convex block 14, and some of the water and sediment fall into the surrounding unidirectional circulation assembly 6, and some of the water and sediment directly fall into the anti-sinking plate 4, so that the water and sediment can flow more efficiently.

In general, the unidirectional flow assembly can be in a closed state after the underwater guide frame is in water, so that the strength of the anti-sinking plate is ensured, and the seawater and the silt above the anti-sinking plate can flow downwards through the unidirectional flow assembly when the underwater guide frame is lifted, so that the adsorption force and the water resistance of the silt received when the anti-sinking plate moves upwards on the anti-sinking plate are reduced, and the whole underwater guide frame is conveniently lifted.
And the drainage protruding block can guide seawater and sediment above the anti-sinking plate to fall into the unidirectional circulation assembly more quickly, so that the resistance to the upward movement of the anti-sinking plate is further reduced.
Finally, the leveling mechanism comprises four hydraulic cylinders which are symmetrically arranged in pairs, and the hydraulic cylinders are connected with the frame body and the anti-sinking plate in a spherical hinge mode, so that the anti-sinking plate can be adjusted at multiple angles, and the leveling efficiency is improved.
In conclusion, the underwater guide frame not only greatly improves the leveling efficiency, but also enables the guide frame to be lifted from the sea water more easily on the premise of ensuring the strength of the anti-sinking plate, and meets the actual requirements more.
