[0002] As the country's new energy power generation projects enter a stage of rapid development, various types of power generation projects are also increasing, and land resources are becoming increasingly scarce. Among them, offshore new energy power generation projects will become the main battlefield in the future. At present, the foundations of offshore photovoltaic projects mostly use prestressed concrete pipe piles or steel pipe piles, and the photovoltaic brackets are basically hoisted as a whole. During the installation of fixed photovoltaic brackets, the position and verticality accuracy of the pile foundation are very high. Any deviation will affect the overall hoisting of the bracket and components, and affect the component layout and power generation efficiency.

[0003] However, in actual engineering applications, in complex offshore environments, pile foundation construction is currently carried out by directly performing pile driving and other pile foundation construction operations after rough positioning through the positioning system on the pile-driving ship.

[0004] In the prior art, the pile driving operation method of roughly positioning the piles through the positioning system on the pile-driving ship does not strictly control the pile position coordinates and the verticality of the pile body. The position of the pile foundation is prone to large deviations, resulting in the inability to smoothly carry out the overall lifting of the photovoltaic bracket and photovoltaic modules, which seriously affects the construction efficiency. Utility Model Content

The orientation relationship between the positioning module and the four cylinders is relatively fixed, and the positioning module is used to locate the coordinates of the four cylinders.

[0009] Preferably, the shape of the inner wall of the cylinder matches the shape of the pile foundation.

[0010] Preferably, the inner diameter of the cylinder matches the outer diameter of the pile foundation.

[0011] Preferably, at least two positioning modules are provided and are symmetrically arranged on the positioning platform.

[0013] Preferably, a leveler is provided on the positioning platform, and the leveler is arranged between two of the positioning modules, and the leveler is used to project horizontal lasers in the directions of the four cylinders.

[0014] Preferably, the four corners of the positioning platform are each provided with lifting ears, and the lifting ears are fixedly connected to the positioning platform.

[0015] Preferably, a locking structure is provided on one side of the truss, and the locking structure comprises a connecting rod, a length direction of which is parallel to the length direction of the truss, and the connecting rod is detachably connected to the truss.

[0016] Preferably, a plurality of pontoons are provided at the bottom of the truss, and the pontoons are fixedly connected to the truss.

[0017] Compared with the prior art, the offshore photovoltaic pile foundation positioning frame provided by the utility model has the following beneficial effects:

[0029] Example 1

[0030] The offshore photovoltaic pile foundation positioning frame provided in this embodiment includes a truss 2, a guide assembly, and a positioning assembly.

[0031] Among them, the guide assembly is arranged on the truss 2 for guiding the pile foundation, and the guide assembly includes four cylinders 1, which are respectively arranged at the four corner positions of the truss 2, and the axial direction of the cylinder 1 is arranged along the vertical direction. The cylinder 1 is fixedly connected to the truss 2, and the upper and lower ends of the cylinder 1 are arranged to be openings for inserting the pile foundation from top to bottom; the positioning assembly is arranged on the truss 2 for positioning the coordinates of the four cylinders 1.

[0032] The cylinder 1 is connected with the truss 2 to ensure the integrity of the device and eliminate errors in the pile pressing process; the inner wall shape of the cylinder 1 matches the shape of the pile foundation, and the inner diameter of the cylinder 1 matches the designed outer diameter of the pile foundation. The pile foundation can be inserted into the guide hole inside the cylinder 1 to perform the pile pressing operation, which can improve the verticality of the pile foundation. At the same time, the coordinates of the four cylinders 1 are positioned by the positioning assembly. Since the pile foundation is inserted into the cylinder 1, the coordinates of the pile foundation can also be positioned by the positioning assembly.

[0033] In this embodiment, the positioning component includes a positioning platform 7, which is arranged on the truss 2 and fixedly connected to the truss 2. A positioning module 6 is arranged on the positioning platform 7. There is a fixed azimuth relationship between the positioning module 6 and the four cylinders 1. The positioning module 6 has a GPS or Beidou positioning system. The GPS or Beidou positioning system can be used to determine the coordinates and elevation of the positioning module 6 on the operating platform. Since there is a fixed azimuth relationship between the positioning module 6 and the four cylinders 1, when the coordinates and elevation of the positioning module 6 are determined, the coordinates and elevation of the cylinder 1 can also be determined.

[0034] In order to further improve the accuracy of positioning, two positioning modules 6 are provided in this embodiment, and the two positioning modules 6 are symmetrically arranged on the positioning platform 7. Each positioning module 6 forms an isosceles triangle position relationship with two adjacent cylinders 1. Using multiple positioning modules can perform point verification, make positioning more accurate, and reduce errors.

[0035] Furthermore, a leveler 9 is provided on the positioning platform 7 , and the leveler 9 is used to project horizontal lasers in the directions of the four cylinders 1 .

[0036] A fixed three-legged bracket is arranged in the center of the operating platform plate, and a leveling instrument 9 is mounted on the three-legged bracket. During the pile foundation construction, according to the designed sinking depth or exposed height, the height of the pile can be accurately determined by projecting the laser of the leveling instrument 9 onto the pile body, so that each group of piles can be kept at the same height, reducing the impact on the bracket installation.

[0037] How to use this embodiment

[0038] The offshore photovoltaic pile foundation positioning frame provided in this embodiment is positioned by the positioning module 6 when in use. The truss 2 is first fixed at the set position, and the pile foundation is inserted into the four cylinders 2 respectively to perform pile foundation pressing operation. When approaching the design elevation, the pile pressing speed is slowed down, and the horizontal laser projected by the sweeper 9 finally determines that the height of the pile foundation reaches the design pile top elevation, that is, the pile foundation construction is completed, and the subsequent pile positions are constructed in sequence. After each group of pile positions are constructed, the fixation of the truss 2 is removed, and the device is moved to the next group of positions, and the above steps are repeated to perform pile foundation operations.

[0039] Example 2

[0040] On the basis of Example 1, the offshore photovoltaic pile foundation positioning frame provided in this embodiment is provided with lifting ears 8 at the four corners of the positioning platform 7 to facilitate the adjustment of the overall position of the device during the construction process so as to make the positioning of the positioning frame more accurate. The lifting ears 8 are fixedly connected to the positioning platform 7. When in use, according to the positioning coordinates of the positioning module 6, the crane can adjust the position of the truss 2 as a whole through the four lifting ears 8.

[0041] After the position of the truss 2 is adjusted and determined, in order to facilitate fixing the position of the truss 2, a locking structure is set on one side of the truss 2, and the locking structure includes a connecting rod 4. The length direction of the connecting rod 4 is parallel to the length direction of the truss 2. The connecting rod 4 is used to connect to the pile-driving ship. A detachable connecting structure is set on the truss 2. The detachable connecting structure is used to fix the connecting rod 4. The detachable connecting structure can select fasteners such as clamps.

[0042] A fixed structure parallel to the length of the hull is provided on one side of the piling vessel. The structure is cylindrical and its diameter matches the size of the clamp. After the positioning module is accurately positioned at the designed position, the clamp is finally fastened and connected.

[0043] In order to improve stability, a plurality of pontoons 3 are fixedly arranged at the bottom of the truss 2. During the process of hoisting and positioning the truss 2, the truss 2 can be ensured to float on the water surface. At the same time, with the help of the locking structure, the positioning time of the truss 2 can be greatly shortened and the positioning efficiency can be improved. The pontoon device can prevent the truss 2 from being submerged in water, improve the overall stability of the truss 2 and not be affected by water waves.

[0044] How to use this embodiment

[0045] The offshore photovoltaic pile foundation positioning frame provided in this embodiment is mainly used in the pile foundation measurement and layout stage. When in use, according to the relationship between the operating range position of the pile driving ship and the designed pile foundation azimuth coordinates, the pile driving ship positioning system is used to accurately locate the position of the pile driving ship, and the anchor is tightened and locked. The truss 2 is placed parallel to the pile driving ship at a certain position away from the pile driving ship by a crane, and the initial position of the auxiliary device is preliminarily determined by the pile driving ship positioning system. The truss 2 is preliminarily connected and fixed with the pile driving ship, and the positioning module 6 on the positioning platform 7 is then accurately adjusted to the designed position by the positioning system and finally fixed with the pile driving ship. The pile foundation is inserted into the cylinder 1 for pile foundation pressing operation. When approaching the design elevation, the pile pressing speed is slowed down, and the pile foundation is determined to reach the designed pile top elevation by the horizontal laser projected by the sweeper, that is, the pile foundation construction is completed, and the subsequent pile positions are constructed in sequence. After each group of pile positions are completed, the connection point with the pile driving ship is removed, and the device is hoisted to the next group of positions, and the above steps are repeated to perform pile foundation operations. It can meet the needs of on-site construction and ensure technicality, economy and rationality.
