Description

Technical Field

[0001] This utility model relates to the field of underwater positioning guide frame technology, specifically an underwater positioning guide frame for offshore wind power foundation pile driving. Background Technology

[0002] A pile driving guide frame is a temporary steel structure auxiliary device used in pile foundation construction to accurately position, guide, and control the verticality (or design inclination) and planar position of piles (such as steel pipe piles and concrete piles). It is widely used in pile foundation projects on water and soft soil foundations, such as bridges, docks, offshore wind power, and platform foundations, and is a key tool to ensure that the quality of pile foundation construction meets design requirements.

[0003] The accuracy and efficiency of guide frame installation is a major issue. Traditional methods rely on large cranes for repeated adjustments, resulting in very low installation efficiency and significant safety hazards. This is especially true in offshore construction environments where wind and waves further exacerbate the installation difficulty and construction risks. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An underwater positioning guide frame for offshore wind power foundation pile driving includes a guiding mechanism and a leveling mechanism. The guiding mechanism includes a support frame, multiple guide cylinders connected to multiple corners of the support frame, and an angle sensor connected to the outer wall of the guide cylinder. The leveling mechanism includes multiple upper and lower arc covers connected to the outer wall of the guide cylinder, a support rod and a hydraulic cylinder rotatably mounted on the outside of the upper arc cover, a transmission rod 1 rotatably connected between the support rod and the hydraulic cylinder, and a transmission rod 2 rotatably connected between the lower arc cover and the hydraulic cylinder.

[0007] By adopting the above technical solution, after the support frame touches the bottom, multiple tilt sensors detect the tilt direction of the support frame in real time and upload the detection data to an external PLC. The PLC analyzes the data based on its built-in algorithm and outputs control commands, causing the movable end of the hydraulic cylinder corresponding to the tilt direction to perform a retraction action. This action reduces the angle between transmission rod one and transmission rod two, thereby pulling the support rod and the bottom box closer to the guide cylinder. Through the coordinated action of the support rod and the bottom box, the posture of the support frame in the tilted state is corrected. This adjustment process continues until the support frame is completely horizontal.

[0008] In a preferred embodiment, the present invention can be further configured such that the leveling mechanism includes multiple base boxes, each of which is fixedly connected to the bottom end of a multiple support rod.

[0009] In a preferred embodiment, this invention can be further configured as follows: multiple tilt sensors are connected in series, and the tilt sensors are electrically connected to an external PLC.

[0010] In a preferred embodiment, the present invention can be further configured as follows: multiple upper arc covers and multiple lower arc covers are evenly spaced and arranged in a ring, with multiple lower arc covers located at the bottom of multiple upper arc covers respectively, and the upper arc covers and lower arc covers are made of the same material.

[0011] In a preferred embodiment, the present invention can be further configured such that the hydraulic cylinder is located at the bottom of the support rod and is electrically connected to an external PLC.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of reinforcing rods are fixedly connected inside the support frame, and the reinforcing rods are made of metal material.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] In this invention, after the support frame touches the bottom, multiple tilt sensors detect the tilt direction of the support frame in real time and upload the detection data to an external PLC. The PLC analyzes the data based on its built-in algorithm and outputs control commands to cause the movable end of the hydraulic cylinder corresponding to the tilt direction to retract. This action reduces the angle between transmission rod one and transmission rod two, thereby pulling the support rod and the bottom box closer to the guide cylinder. Through the coordinated action of the support rod and the bottom box, the posture of the support frame in the tilted state is corrected. This adjustment process continues until the support frame is completely horizontal. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an underwater positioning guide frame for offshore wind power foundation pile driving.

[0026] Example 1:

[0027] Combination Figure 1-4 As shown, the present invention provides an underwater positioning guide frame for offshore wind power foundation pile driving, including a guide mechanism 100 and a leveling mechanism 200. The guide mechanism 100 includes a support frame 110, a plurality of guide cylinders 120 respectively connected to a plurality of corners of the support frame 110, and an inclination sensor 130 connected to the outer wall of the guide cylinder 120.

[0028] The leveling mechanism 200 includes multiple upper arc covers 210 and multiple lower arc covers 220 connected to the outer wall of the guide cylinder 120, a support rod 230 and a hydraulic cylinder 240 rotatably mounted on the outside of the upper arc cover 210, a transmission rod 250 rotatably connected between the support rod 230 and the hydraulic cylinder 240, and a transmission rod 260 rotatably connected between the lower arc cover 220 and the hydraulic cylinder 240.

[0029] Specifically, the leveling mechanism 200 also includes multiple base boxes 270, which are fixedly connected to the bottom ends of multiple support rods 230 respectively. The base boxes 270 are provided to increase the contact area between the support rods 230 and the seabed, prevent the support rods 230 from inserting into the seabed, and make it easier for the support rods 230 to move horizontally along the seabed.

[0030] Furthermore, multiple tilt sensors 130 are connected in series, and the tilt sensors 130 are electrically connected to an external PLC. This connection method facilitates the simultaneous activation of multiple tilt sensors 130 and provides conditions for analyzing the tilting situation.

[0031] Furthermore, the hydraulic cylinder 240 is located at the bottom of the support rod 230 and is electrically connected to an external PLC. This structural design provides conditions for intelligent adjustment of the horizontal state of the support frame 110.

[0032] Example 2:

[0033] Combination Figure 1 , 3 and Figure 4 As shown, based on Embodiment 1, multiple upper arc covers 210 and multiple lower arc covers 220 are evenly spaced and arranged in a ring. Multiple lower arc covers 220 are located at the bottom of multiple upper arc covers 210. The upper arc covers 210 and lower arc covers 220 are made of the same material. This structural design reduces the manufacturing difficulty of both.

[0034] Example 3:

[0035] Combination Figure 1 As shown, in the above embodiment, a plurality of reinforcing rods 300 are fixedly connected inside the support frame 110. The reinforcing rods 300 are made of metal material. The installation of reinforcing rods 300 can improve the structural strength of the support frame 110.

[0036] The working principle and usage process of this utility model are as follows: In the initial state, the device is transported to the designated piling position at sea by hoisting equipment; subsequently, the support frame 110 and the guide cylinder 120 begin to sink; when the support frame 110 contacts the seabed, it is in a non-horizontal state due to the influence of the seabed topography; at this time, multiple tilt sensors 130 detect the tilt direction of the support frame 110 in real time and upload the detection data to an external PLC. The PLC analyzes the data based on its built-in algorithm and outputs control commands, causing the movable end of the hydraulic cylinder 240 corresponding to the tilt direction to perform a retraction action. This action drives the angle between the first transmission rod 250 and the second transmission rod 260 to decrease, thereby pulling the support rod 230 and the bottom box 270 closer to the guide cylinder 120. Through the synergistic action of the support rod 230 and the bottom box 270, the attitude of the support frame 110 in the tilted state is corrected. This adjustment process continues until the support frame 110 is completely horizontal.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
