[0028] The bearing frame 5121 cooperates with the first supporting rod 5122 to support and position the first guide rod 5123 in the inner side of the fixing ring 2, and the sleeve 4 cooperates with the horizontal rod 5127 to position the vertical sliding rail 5128 and the vertical rack 5129. Initially, the horizontal control rod 5124 remains in a horizontal state, when the pile basic body 1 produces settlement in the vertical direction, the sleeve 4 moves synchronously along the vertical direction driven by the pile basic body 1, the vertical sliding rail 5128 and the vertical rack 5129 move synchronously driven by the sleeve 4, the vertical rack 5129 meshes with the first positioning rack 51210 to drive the horizontal control rod 5124 to rotate on the surface of the bearing frame 5121 in the vertical plane, the first extrusion block 5125 slides on the surface of the first guide rod 5123 driven by the horizontal control rod 5124, and the first extrusion block 5125 extrudes the first positioning spring 5126 when sliding, and the first positioning spring 5126 applies a synchronous pushing force to the first pressure sensor 511. As the settlement amplitude of the pile basic body 1 gradually increases, the rotation amplitude of the horizontal control rod 5124 gradually increases synchronously, and the pushing force of the first extrusion block 5125 to the first positioning spring 5126 gradually increases synchronously.

[0029] As shown in the drawings, Figure 1 , Figure 4 , Figure 5 , Figure 6As shown, in a preferred embodiment of the present invention, the second adjusting part 522 includes two sets of opposingly distributed second support rods 5221 fixedly installed on the inner sidewall of the fixing ring 2. An arc-shaped second guide rod 5222 is fixedly installed at the end of the second support rod 5221 away from the fixing ring 2. Two sets of second pressure sensors 521 are provided and are oppositely distributed on the surface of the second guide rod 5222. A second positioning spring 5223 is provided on the surface of the second pressure sensor 521 and sleeved on the outside of the second guide rod 5222. A bearing rod 5224 is fixedly installed on the inner sidewall of the fixing ring 2. A vertical control rod 5225 is rotatably mounted on the surface of the carrier rod 5224. A second pressing block 5226 is fixedly mounted on one end of the vertical control rod 5225 facing the second guide rod 5222. The second pressing block 5226 is slidably mounted on the surface of the second guide rod 5222. A transverse slide rail 5227 is fixedly mounted on the side wall of the sleeve 4. A transverse rack 5228 is provided on the surface of the transverse slide rail 5227. An arc-shaped second positioning rack 5229 is fixedly mounted on one end of the second guide rod 5222 away from the second pressing block 5226. The second positioning rack 5229 is meshed with the transverse rack 5228.

[0030] The second support rod 5221 supports and positions the second guide rod 5222 inside the fixed ring 2. The bearing rod 5224 supports and positions the vertical control rod 5225 inside the fixed ring 2. The sleeve 4 supports and positions the transverse slide rail 5227 and the transverse rack 5228 outside the pile body 1. When the pile body 1 tilts, the pile body 1 and the sleeve 4 cooperate to push the transverse slide rail 5227 and the transverse rack 5228 to move synchronously. The transverse rack 5228 meshes with the second positioning rack 5229, which can drive the vertical control rod 5225 to rotate on the surface of the bearing rod 5224. The vertical control rod 5225 drives the second pressing block 5226 to slide synchronously on the surface of the second guide rod 5222. When the second pressing block 5226 slides, it applies a thrust to the second positioning spring 5223. The second positioning spring 5223 applies pressure to the second pressure sensor 521 synchronously. As the tilt of the pile body 1 gradually increases, the rotation amplitude of the vertical control rod 5225 gradually increases, and the squeezing force of the second squeezing block 5226 on the second positioning spring 5223 gradually increases.

[0031] like Figure 1 , Figure 5 As shown, in a preferred embodiment of the present invention, the rotating assembly 6 includes two sets of side-by-side baffles 61 fixedly mounted on the surface of the fixed ring 2, and a stop bar 62 fixedly mounted on the surface of the sleeve 4, the stop bar 62 being located between the two sets of baffles 61.

[0032] The sleeve 4 is rotatably installed outside the pile base body 1, the fixing ring 2 is rotatably installed outside the supporting ring 32, the sleeve 4 and the fixing ring 2 are matched with each other, the positions of the first pressure sensor 511 and the second pressure sensor 521 can be adjusted in all directions outside the pile base body 1, and then the deformation of the pile base body 1 can be detected in all directions, the stop lever 62 and the two groups of baffle plates 61 are matched with each other, and the rotation of the sleeve 4 and the fixing ring 2 can be controlled synchronously.

[0033] As shown in Figure 1 , Figure 2 , as a preferred embodiment of the present application, a plurality of guide plates 7 are arranged on the surface of the fixing ring 2 in the form of a ring and at equal intervals. The wind or water power can push the guide plates 7 to move, and the guide plates 7 control the rotation of the fixing ring 2 on the surface of the supporting ring 32.

[0034] As shown in Figure 1 , Figure 2 , as a preferred embodiment of the present application, a plurality of ball bearings 8 are movably arranged on the surface of the supporting ring 32 at equal intervals, and the ball bearings 8 are in contact with the inner top wall of the fixing ring 2.

[0035] The working principle of the present application is as follows: in use, the pile base body 1 is installed on the sea, the base 34 is installed at a deep place of the seabed, the base 34 positions the supporting rods 33, the plurality of supporting rods 33 position the supporting ring 32, the supporting ring 32 positions the fixing ring 2, and the fixing ring 2 is stably sleeved outside the pile base body 1. During the long-time use of the pile base body 1, initially, the horizontal control lever 5124 is kept in a horizontal state, when the pile base body 1 produces settlement in the vertical direction, the pile base body 1 drives the sleeve 4 to move synchronously in the vertical direction, the sleeve 4 drives the vertical sliding rail 5128 and the vertical rack 5129 to move synchronously, the vertical rack 5129 is in meshing transmission with the first positioning rack 51210, so as to drive the horizontal control lever 5124 to rotate on the surface of the bearing frame 5121 in the vertical plane, the horizontal control lever 5124 drives the first extrusion block 5125 to slide on the surface of the first guide rod 5123, and the first extrusion block 5125 extrudes the first positioning spring 5126 when sliding, so that the first positioning spring 5126 synchronously applies a pushing force to the first pressure sensor 511. When the settlement amplitude of the pile base body 1 gradually increases, the rotation amplitude of the horizontal control lever 5124 synchronously gradually increases, and the pushing force of the first extrusion block 5125 to the first positioning spring 5126 synchronously gradually increases. The pressure change trend detected by the first pressure sensor 511 can synchronously detect the settlement trend of the pile base body 1 in the vertical direction. When the pressure value of the first pressure sensor 511 reaches a predetermined limit value, it means that the pile base body 1 reaches the settlement limit.

[0036] On the sea surface, the lateral thrust of the wind wave on the pile base body 1 can easily cause the pile base body 1 to tilt. During continuous use, when the pile base body 1 tilts, the pile base body 1 cooperates with the sleeve 4 to push the transverse slide rail 5227 and the transverse rack 5228 to move synchronously. The transverse rack 5228 is engaged with the second positioning rack 5229 to drive the vertical control rod 5225 to rotate on the surface of the bearing rod 5224. The vertical control rod 5225 drives the second extrusion block 5226 to slide synchronously on the surface of the second guide rod 5222. When the second extrusion block 5226 slides, it applies a thrust force to the second positioning spring 5223, and the second positioning spring 5223 applies a pressure to the second pressure sensor 521 synchronously. When the tilt amplitude of the pile base body 1 gradually increases, the rotation amplitude of the vertical control rod 5225 gradually increases synchronously, and the extrusion force of the second extrusion block 5226 on the second positioning spring 5223 gradually increases synchronously. The pressure change trend detected by the second pressure sensor 521 can be used to detect the tilt amplitude of the pile base body 1 synchronously. When the pressure value of the second pressure sensor 521 reaches a predetermined limit value, it means that the pile base body 1 has reached the tilt limit.

[0037] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
