Description

Technical Field

[0001] This invention relates to the field of wind turbine foundation pile construction technology, and in particular to a wind turbine foundation pile stabilization platform and construction method. Background Technology

[0002] Currently, there are two development trends in offshore wind farm construction: first, the construction water depth is expanding from near-shore shallow waters to deep seas, with some projects under construction or planned reaching depths of 40-60 meters; second, the single-unit capacity of wind turbines is continuously increasing, and the turbines are gradually becoming larger. This inevitably places new demands on the foundations of offshore wind turbines. Currently, the foundation types for wind turbines in use include monopile, high-pile cap, gravity, negative pressure tank, and jacket foundations. Among these, the jacket foundation is the most commonly used in deep-sea wind farm projects in recent years due to its simple structure, safety and reliability, fast construction speed, and lower requirements for construction equipment.

[0003] Currently, the pile driving control of offshore wind turbine jacket foundations in China generally adopts pile stabilization platforms. These platforms are further divided into integral pile stabilization platforms, which use a cage opening for coarse positioning at the top and a guide cylinder for precise verticality control at the bottom, and floating pile stabilization platforms, which only use upper jacks to control verticality and have no lower structure. Most existing integral and floating pile stabilization platforms have significant drawbacks. Integral pile stabilization platforms can achieve high-precision control of the verticality of steel pipe piles, but because the upper cage opening does not restrict the displacement of the steel pipe piles, the difficulty of pile driving is relatively high, the time consumption is relatively long, and there is a risk that the steel pipe piles may collide with the guide cylinders, causing deformation of the guide cylinders. Floating pile stabilization platforms do not have the above problems, but because they lack a lower guide cylinder structure, the verticality and planar position control accuracy of the steel pipe piles is relatively low. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above and / or existing wind turbine foundation pile stabilization platforms and construction methods, the present invention is proposed.

[0006] Therefore, the problem to be solved by this invention is that most of the existing integral pile stabilization platforms and floating pile stabilization platforms have obvious drawbacks. Integral pile stabilization platforms can achieve high-precision control of the verticality of steel pipe piles, but because the upper cage does not restrict the displacement of the steel pipe piles, the difficulty of pile insertion is relatively high and the time consumption is relatively long. There is also a risk that the steel pipe piles will collide with the guide cylinder, causing the guide cylinder to deform. Although floating pile stabilization platforms do not have the above problems, they have lower accuracy in controlling the verticality and planar position of steel pipe piles because they do not have a lower guide cylinder structure.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wind turbine foundation pile stabilization platform, comprising a stabilization component including an anti-settlement plate, a sleeve, a fixing frame, a guide sleeve, a support platform, and a connector. The sleeve is fixed to the top of the anti-settlement plate, the fixing frame is fixed to the outside of the sleeve, the guide sleeve is fixed on the fixing frame, the support platform is disposed above the sleeve, the connector is located between the sleeve and the support platform, and the support platform is provided with a positioning hole.

[0008] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, the connecting component includes a fixing sleeve and a flange, the fixing sleeve is located on one side of the sleeve, and the flange is fixed to the fixing sleeve on one side.

[0009] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, the connecting member further includes a horizontal tie rod and a diagonal tie rod, one end of the horizontal tie rod is fixed to the fixing sleeve, and the diagonal tie rod is fixed to one side of the horizontal tie rod.

[0010] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, the stabilization component further includes a guide pipe, which is fixed to the top of the guide sleeve.

[0011] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, there are four guide sleeves, which are respectively fixed at the four corners of the fixing frame.

[0012] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, the guide pipe opening is shaped as larger at the top and smaller at the bottom.

[0013] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, the anti-settlement plate is provided with drainage holes.

[0014] As a preferred embodiment of the wind turbine foundation pile stabilization platform of the present invention, there are four positioning holes, which are located at the four corners of the support platform.

[0015] As a preferred embodiment of the wind turbine foundation pile construction method of the present invention, the stabilizing component is transported to a designated location by a transport ship and positioned therein, allowing it to slowly sink to a certain depth on the seabed.

[0016] The stabilizing components are kept vertical by the bottom anti-sinking plate, and the supporting platform is leveled by the leveling mechanism.

[0017] The wind turbine foundation piles are fed into the positioning holes of the support platform and then inserted into the guide sleeve below until the foundation piles are lowered to the mud surface and reach a balanced state. During this process, the angle of the foundation piles is continuously adjusted by the leveling mechanism above to make the foundation piles as vertical as possible.

[0018] Finally, the wind turbine foundation piles are driven into the required elevation using piling equipment.

[0019] The beneficial effects of this invention are as follows: by setting the stabilizing component, multiple foundation piles can be positioned during the foundation pile construction process, which can avoid the foundation piles from colliding during construction. Furthermore, the horizontal state of the stabilizing component can be adjusted, so that multiple foundation piles can be in a vertical state at the same time, thereby reducing construction difficulty and time costs and improving construction efficiency.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1-2 This is the first embodiment of the present invention. This embodiment provides a wind turbine foundation pile stabilization platform. The wind turbine foundation pile stabilization platform includes a stabilization component 100, including an anti-sinking plate 101, a sleeve 102, a fixing frame 103, a guide sleeve 104, a support platform 105, and a connector 106. The sleeve 102 is fixed to the top of the anti-sinking plate 101, the fixing frame 103 is fixed to the outside of the sleeve 102, the guide sleeve 104 is fixed to the fixing frame 103, the support platform 105 is disposed above the sleeve 102, and the connector 106 is located between the sleeve 102 and the support platform 105. The support platform 105 is provided with a positioning hole Z.

[0036] The fixing frame 103 is used to support and fix the guide sleeve 104. The guide sleeve 104 is used to position the foundation pile to prevent the foundation pile from shifting during installation. The support platform 105 is connected to the sleeve 102 by the connector 106. The number of connectors 106 can be increased according to the depth of the sea level to ensure that the support platform 105 has sufficient height.

[0037] Example 2

[0038] Reference Figures 1-2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the connector 106 includes a fixing sleeve 106a and a flange 106b. The fixing sleeve 106a is located on one side of the sleeve 102, and the flange 106b is fixed to the fixing sleeve 106a on one side.

[0040] There are four fixed sleeves 106a, which are connected to four sleeves 102 respectively. A flange 106b is fixed to the top of the sleeve 102. The fixed sleeve 106a is connected to the sleeve 102 by bolts and two flanges 106b. The support platform 105 is fixed to the uppermost fixed sleeve 106a. The height of the support platform 105 can be increased by adding a fixed sleeve 106a in the center.

[0041] Specifically, the connector 106 also includes a horizontal tie rod 106c and a diagonal tie rod 106d. One end of the horizontal tie rod 106c is fixed to the fixing sleeve 106a, and the diagonal tie rod 106d is fixed to one side of the horizontal tie rod 106c.

[0042] The stability among the four fixed sleeves 106a is increased by the horizontal tie rod 106c and the diagonal tie rod 106d.

[0043] Specifically, the stabilizing component 100 also includes a guide port 107, which is fixed to the top of the guide sleeve 104.

[0044] Specifically, there are four guide sleeves 104, which are fixed to the four corners of the fixing frame 103 respectively.

[0045] Specifically, the guide tube 107 is wider at the top and narrower at the bottom.

[0046] By setting the guide pipe opening 107 into a funnel shape that is larger at the top and smaller at the bottom, it is easier to insert the foundation pile into the guide sleeve 104.

[0047] Specifically, drainage holes X are provided on the anti-sinking plate 101.

[0048] The silt and sewage at the bottom of the anti-sinking plate 101 can be drained through the drainage hole X, making the anti-sinking plate 101 more stable.

[0049] Specifically, there are four positioning holes Z, located at the four corners of the support platform 105.

[0050] Specifically, the stabilizing component 100 is transported to a designated location by a transport ship and positioned there, allowing it to slowly sink to a certain depth on the seabed.

[0051] The stabilizing component 100 is kept vertical by the bottom anti-sinking plate 101, and the supporting platform 105 is leveled by the leveling mechanism.

[0052] The wind turbine foundation pile is fed into the positioning hole Z of the support platform 105 and the wind turbine foundation pile is put into the guide sleeve 104 below until the foundation pile is lowered to the mud surface and is in a balanced state. During this process, the angle of the foundation pile is continuously adjusted by the leveling mechanism above to make the foundation pile as vertical as possible.

[0053] Finally, the wind turbine foundation piles are driven into the required elevation using piling equipment.

[0054] When using it, the specific steps are as follows:

[0055] 1. Stabilizing Component 100 Sealing: The transport ship transports the stabilizing component 100 to the machine position according to the construction requirements. The lifting ship uses a crane to lift the stabilizing component 100 to a certain height above the transport ship. Surveyors observe the azimuth and coordinates of the stabilizing component 100 using GPS instruments pre-installed on the upper platform of the support platform 105. The crane operator on the lifting ship adjusts the position of the hook according to the surveyors' instructions. At the same time, the staff reserved on the deck of the lifting ship use a winch to pull the guy rope of the stabilizing component 100 to adjust the azimuth of the stabilizing component 100.

[0056] After the coordinates and azimuth of the stabilizing component 100 are adjusted, the crane operator on the lifting vessel slowly lowers the main hook to allow the stabilizing component 100 to enter the water until the lower anti-sinking plate 101 touches the mud. The main hook is then lowered further to gradually reduce the load on the sling until the stabilizing component 100 has sunk completely. During this period, the surveyors monitor the position and azimuth of the stabilizing component 100. If the level deviation is greater than 1%, the lifting vessel must adjust the boom in time to control the platform level within 5‰.

[0057] After the stabilizing component 100 has sunk completely, the crane is no longer under any load. The position, azimuth, and levelness of the stabilizing component 100 are checked. If the conditions are met, the hook is removed. At this time, the stabilizing component 100 can be leveled by the leveling mechanism to make the stabilizing component 100 vertical. In the leveling process, the following scheme is preferred in this example. This scheme is the prior art.

[0058] 2. Auxiliary pile installation: The auxiliary pile is lifted and turned over by the crane of the lifting vessel. After the auxiliary pile is turned over, the lifting vessel inserts the auxiliary pile into the casing 102. After the auxiliary pile is inserted and sinks into the mud by its own weight, the hook is removed and the above operation is repeated for the next auxiliary pile - until all 4 auxiliary piles are sinking into the mud. Then, the auxiliary piles are driven diagonally with a vibratory hammer. The top of the auxiliary pile is about 4m higher than the working platform of the stabilizing component 100.

[0059] 3. Adjustment of Stabilizing Component 100: The platform is symmetrically arranged with anti-lifting eye plates in the auxiliary direction. After the auxiliary piles are fixed, ring beam lifting lugs are added to the upper edge of the four auxiliary piles, and the ring beam lifting lugs and the anti-lifting eye plates on the stabilizing component 100 are placed in the same plane and relative position. Lifting slings with hydraulic cylinder adjustment function are arranged between the ring beam lifting lugs and the anti-lifting eye plates. The level of the stabilizing component 100 is adjusted by the lifting slings on the four auxiliary piles, and its deviation is controlled within 2‰. After the adjustment is completed, wedges are inserted into the gap between the auxiliary piles and the guide frame of the stabilizing component 100 for fixation.

[0060] 4. Piling using a pile driving control system: The transport ship transports the foundation steel pipe piles to the site. The lifting ship flips the steel pipe piles from a horizontal position to an vertical position. After flipping, the piles are hoisted into the positioning hole Z of the support platform 105. The center of the steel pipe pile is precisely adjusted through the positioning hole Z to be at the center of the cage opening and aligned with the center of the guide tube. The piles are then slowly lowered while maintaining their position. After entering the water, the underwater monitoring system ensures that the foundation piles fall smoothly into the guide sleeve 104 below until they reach a balanced state on the mud surface. During this process, the angle of the foundation piles is continuously adjusted by the upper leveling mechanism to make them as vertical as possible. Finally, the lifting equipment is released, the pile hammer is connected, and the pile driving operation is carried out. During the pile driving process, the verticality of the foundation piles is monitored. The leveling mechanism can be used to correct the deviation of the foundation piles within the allowable range. The above operation is repeated until all the remaining steel pipe piles that need to be driven are driven.

[0061] 5. Removal and relocation of stabilizing component 100: After the pile driving construction is completed, the fixing wedges between the auxiliary pile and the platform are removed. The auxiliary piles are pulled out one by one using the crane of the hoisting vessel and placed on the transport vessel. Then, the stabilizing component 100 is lifted and placed on the transport vessel, and the transport vessel moves the stabilizing component 100 and the auxiliary pile to the next machine position.

[0062] Example 3

[0063] Reference Figures 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0064] The leveling mechanism includes a leveling component 200, which is located on the top of the support platform 105. It includes a moving rod 201, an adjusting component 202, a locking component 204, and a triggering component 205. The moving rod 201 is inserted into the sleeve 102. The adjusting component 202 is located on the top of the support platform 105. The locking component 204 is located inside the adjusting component 202. The triggering component 205 is located inside the adjusting component 202.

[0065] There are four movable rods 201, which are inserted into four sleeves 102 respectively. In the initial state, the bottom of the movable rod 201 extends through to the bottom of the anti-sinking plate 101 and the top extends to the bottom of the support platform 105. A bolt is provided on one side of the sleeve 102 to lock the movable rod 201 in the sleeve 102, so as to prevent the movable rod 201 from moving in the sleeve 102 when the support platform 105 is moved.

[0066] Once the anti-sinking plate 101 is placed stably, the bolts are removed to release the restriction on the moving rod 201. If the support platform 105 is tilted, the moving rod 201 in the tilt direction can be moved downward by the adjusting component 202, so that the moving rod 201 lifts the tilted side of the support platform 105 upward, thereby adjusting the support platform 105 to a horizontal state.

[0067] By setting the locking component 204, when the support platform 105 is adjusted to a horizontal state, it is used to lock the adjusting component 202, thereby preventing the adjusting component 202 from loosening and causing the moving rod 201 to move, which in turn causes the support platform 105 to tilt.

[0068] By setting the trigger 205, when the support platform 105 tilts, the adjusting member 202 can only drive the moving rod 201 on the tilted side to move, while the moving rods 201 in other directions will not move. And when the support platform 105 is adjusted to a horizontal state, the adjusting member 202 can no longer drive the moving rods 201 to move, thereby avoiding the situation where the moving rods 201 move too much, which would cause the support platform 105 to tilt to the other side.

[0069] The adjusting component 202 includes a fixed box 202a, a threaded rod 202b, a fixed frame 202c, a threaded plate 202d, a positioning block 202e, a positioning post 202f, a rack 202g, a first gear 202h, and a first spring 202i. The fixed box 202a is located on the top of the support platform 105. The threaded rod 202b is inserted into the fixed box 202a. The fixed frame 202c is fixed inside the fixed box 202a. The threaded plate 202d is located inside the fixed frame 202c. One side of the positioning block 202e is fixed to the threaded plate 202d. The positioning post 202f is fixed inside the fixed frame 202c. The rack 202g is fixed to the top of the threaded plate 202d. The first gear 202h is rotatably connected to the fixed frame 202c via a rotating shaft. The two ends of the first spring 202i are respectively fixed to the two positioning blocks 202e.

[0070] The number of adjusting components 202 corresponds to the number of moving rods 201. After the support platform 105 is placed stably, the fixing box 202a is placed on top of the support platform 105 and fixed with bolts. At this time, the bottom of the threaded rod 202b will contact the top of the moving rod 201. When the threaded rod 202b moves downward, it can push the moving rod 201 downward, thereby adjusting the support platform 105 to a horizontal state. There are two threaded plates 202d, located on both sides of the threaded rod 202b. The number of positioning blocks 202e corresponds to the number of threaded plates 202d. 202f is movably connected to the positioning block 202e. The two work together to position the threaded plate 202d, preventing the threaded plate 202d from shifting during movement. The number of racks 202g corresponds to the number of threaded plates 202d. The two racks 202g are located at the top and bottom of the first gear 202h, respectively. The two work together to allow the two threaded plates 202d to mesh with the threaded rod 202b simultaneously. The first spring 202i applies a pushing force to the two positioning blocks 202e, allowing the threaded plates 202d to separate from the threaded rod 202b in a timely manner.

[0071] When the two threaded plates 202d move in the center and engage with the threaded rod 202b, the threaded rod 202b rotates while the threaded plates 202d move downwards, thereby pushing the moving rod 201 downwards and adjusting the horizontal state of the support platform 105.

[0072] Adjusting component 202 also includes a second gear 202j, a gear ring 202k, a motor 202l, a rotating sleeve 202m, a first limiting block 202n, a positioning sleeve 202o, a locking block 202p, and a second spring 202q. The second gear 202j is rotatably connected to the inner top wall of the fixed box 202a, the gear ring 202k is rotatably connected to the inner top wall of the fixed box 202a and meshes with the second gear 202j, and the rotating sleeve 202m is rotatably connected to the inner top wall of the fixed box 202a. The first limiting block 202n, the positioning sleeve 202o, the locking block 202p, and the second spring 202q are also included. The first limiting block 202n is fixed inside the rotating sleeve 202m. The threaded rod 202b has a limiting groove 200-1. The first limiting block 202n engages with the limiting groove 200-1. The positioning sleeve 202o is fixed inside the second gear 202j. The locking block 202p is located inside the positioning sleeve 202o. The two ends of the second spring 202q are fixed to the locking block 202p and the inner wall of the positioning sleeve 202o, respectively. The rotating sleeve 202m has a locking groove 200-2. The locking block 202p engages with the locking groove 200-2.

[0073] The gear ring 202k is fixed to the output shaft of the motor 202l. The rotating sleeve 202m is connected to the threaded rod 202b through the cooperation of the first limiting block 202n and the limiting groove 200-1. When the rotating sleeve 202m rotates, it can drive the threaded rod 202b to rotate. The locking block 202p is movably connected to the positioning sleeve 202o. There are multiple locking grooves 200-2, which are evenly distributed in a ring on the outside of the rotating sleeve 202m. The locking block 202p is movably connected to the positioning sleeve 202o. The second spring 202q is used to apply a pulling force to the locking block 202p so that the locking block 202p can separate from the locking groove 200-2 after the restriction is released.

[0074] When the locking block 202p engages with the locking slot 200-2, the starting motor 202l drives the gear ring 202k to rotate, which in turn drives the second gear 202j to rotate. The second gear 202j, through the engagement of the locking block 202p and the locking slot 200-2, drives the rotating sleeve 202m to rotate. The rotating sleeve 202m, through the engagement of the first limiting block 202n and the limiting groove 200-1, drives the threaded rod 202b to rotate, causing the threaded rod 202b to move downward. This allows the threaded rod 202b to drive the moving rod 201 to move downward, thereby enabling the horizontal adjustment of the support platform 105.

[0075] The adjusting component 202 also includes a support plate 202r, a push block 202s, a positioning shaft 202t, and a connecting plate 202u. The support plate 202r is located below the second gear 202j, the push block 202s is fixed to the top of the support plate 202r, the positioning shaft 202t is fixed to the bottom of the second gear 202j, and the connecting plate 202u is located at the bottom of the support plate 202r.

[0076] The top side of the push block 202s is inclined, and the positioning shaft 202t is movably connected to the bearing plate 202r to position the bearing plate 202r so that the bearing plate 202r can rotate with the second gear 202j. The connecting plate 202u is U-shaped. When the connecting plate 202u moves upward, it will push the bearing plate 202r and the push block 202s to move upward, so that the push block 202s presses the oblique side of the locking block 202p, thereby making the locking block 202p engage with the locking groove 200-2.

[0077] The locking component 204 includes a stabilizing sleeve 204a, a moving block 204b, a movable block 204c, a limiting plate 204d, a second limiting block 204e, a third spring 204f, and a stop block 204g. The stabilizing sleeve 204a is fixed to the top of the fixing frame 202c. An annular groove 200-3 is formed inside the stabilizing sleeve 204a. The moving block 204b slides in the annular groove 200-3. The movable block 204c is located inside the moving block 204b. The limiting plate 204d is fixed to one side of the movable block 204c. The second limiting block 204e is fixed to one side of the limiting plate 204d. The third spring 204f is fixed to one side of the movable block 204c. A first chamber 200-4 is formed inside the movable block 204c. The stop block 204g is located inside the first chamber 200-4.

[0078] The movable block 204b is T-shaped, the annular groove 200-3 is T-shaped, the movable block 204c is movably connected to the movable block 204b, one side of the limiting plate 204d is threaded, the limiting plate 204d is threaded to the threaded rod 202b, the second limiting block 204e is engaged with the limiting groove 200-1, the third spring 204f is used to apply a pushing force to the movable block 204c, so that the movable block 204c can drive the limiting plate 204d to fit against the threaded rod 202b, the bottom of the stop block 204g is arc-shaped and extends to the outside of the movable block 204b, the stop block 204g locks the limiting plate 204d, so that the limiting plate 204d can be rigidly connected to the threaded rod 202b, thereby making the restriction of the threaded rod 202b more stable.

[0079] When the limiting plate 204d is threadedly connected to the threaded rod 202b, and the second limiting block 204e engages with the limiting groove 200-1, the threaded rod 202b can be locked by their cooperation, preventing it from moving up and down. This, in turn, limits the movement rod 201, preventing it from becoming loose. When the limiting plate 204d moves to one side and separates from the threaded rod 202b, the second limiting block 204e does not... It will separate from the limiting groove 200-1, thereby releasing the restriction on the threaded rod 202b, allowing the threaded rod 202b to rotate. When the threaded rod 202b rotates, it will drive the limiting plate 204d and the movable block 204c to rotate through the second limiting block 204e, and cause the movable block 204b to slide in the annular groove 200-3. This allows the second limiting block 204e to always be engaged with the limiting groove 200-1 without affecting the normal rotation of the threaded rod 202b.

[0080] The locking component 204 also includes a locking block 204h, a fourth spring 204i, and a pressing rod 204j. A second chamber 200-5 is provided in the moving block 204b. The locking block 204h is located in the second chamber 200-5. A locking hole 200-7 is provided on the inner wall of the annular groove 200-3. The locking block 204h engages with the locking hole 200-7. The fourth spring 204i is fixed to one side of the locking block 204h. The pressing rod 204j is fixed to one side of the moving block 204c. A force-receiving groove 200-6 is provided on the locking block 204h. The inner wall of the force-receiving groove 200-6 is inclined.

[0081] When the locking block 204h engages with the lock hole 200-7, the two work together to limit the movement block 204b, preventing it from rotating. The fourth spring 204i applies a pushing force to the locking block 204h, making the engagement between the locking block 204h and the lock hole 200-7 more secure. There are multiple lock holes 200-7, which are evenly distributed in a ring within the annular groove 200-3. When the movable block 204c moves, it drives the pressing rod 204j to press against the inclined surface of the inner wall of the force groove 200-6, thereby separating the locking block 204h from the lock hole 200-7 and releasing the restriction on the movement block 204b, allowing it to slide within the annular groove 200-3.

[0082] The locking component 204 also includes a compression sleeve 204k, a fixing rod 204l, an annular plate 204m, a compression block 204n, a force-bearing block 204o, a guide post 204p, and a guide block 204q. The compression sleeve 204k is located outside the threaded rod 202b. The fixing rod 204l is fixed to one side of the compression sleeve 204k. The annular plate 204m is fixed to one end of the fixing rod 204l. The compression block 204n is fixed to one side of the threaded plate 202d. The force-bearing block 204o is fixed to one side of the compression sleeve 204k. The guide post 204p is fixed to the inside of the stabilizing sleeve 204a. The guide block 204q is fixed to one side of the compression sleeve 204k.

[0083] The top of the extrusion sleeve 204k is inclined. The fixing rod 204l is used to connect the annular plate 204m to the extrusion sleeve 204k. The guide post 204p is movably connected to the guide block 204q. There are two of each, located on both sides of the extrusion sleeve 204k. The two work together to position the extrusion sleeve 204k and prevent it from shifting during movement. One side of the force block 204o is inclined, and one side of the connecting plate 202u is fixed to the extrusion sleeve 204k. When the extrusion sleeve 204k moves upward, it will simultaneously drive the connecting plate 202u to move upward.

[0084] When the threaded plate 202d moves, it simultaneously drives the pressing block 204n to press the inclined surface of the force-bearing block 204o. Through the cooperation of the two, the pressing sleeve 204k moves upward, so that the top inclined surface of the pressing sleeve 204k presses the limiting plate 204d, thereby separating the limiting plate 204d from the threaded rod 202b. At the same time as the pressing sleeve 204k moves upward, it drives the annular plate 204m to press the stop block 204g, so that the stop block 204g enters the first chamber 200-4 and releases the restriction on the movable block 204c, thereby allowing the movable block 204c and the limiting plate 204d to move.

[0085] The trigger element 205 includes a connecting rod 205a, a sensing ball 205b, a support sleeve 205c, an arc-shaped plate 205d, a movable sleeve 205e, a fifth spring 205f, a push rod 205g, a stabilizing block 205h, a sixth spring 205i, a fixing plate 205j, and a seventh spring 205k. The connecting rod 205a is fixed to one side of the threaded plate 202d, the sensing ball 205b is located inside the fixing box 202a, the support sleeve 205c is located outside the sensing ball 205b, and the arc-shaped plate 205d is disposed on one side of the connecting rod 205a. The connecting rod 205a... A third chamber 200-8 is provided inside 5a. The movable sleeve 205e is located inside the third chamber 200-8. The two ends of the fifth spring 205f are fixed to the inner walls of the movable sleeve 205e and the third chamber 200-8, respectively. The push rod 205g is fixed to one side of the arc plate 205d. The stabilizing block 205h is located inside the movable sleeve 205e. The two ends of the sixth spring 205i are fixed to the inner walls of the stabilizing block 205h and the movable sleeve 205e, respectively. The fixed plate 205j is fixed to the outside of the connecting rod 205a. The seventh spring 205k is fixed to one side of the fixed plate 205j.

[0086] The connecting rod 205a extends through to the outside of the fixed frame 202c and is movably connected to the fixed frame 202c. The support sleeve 205c is used to position the sensing ball 205b. The arc plate 205d contacts the support sleeve 205c. The fifth spring 205f applies tension to the movable sleeve 205e, allowing the movable sleeve 205e to reset after being released from its restriction. One side of the push rod 205g is inclined and contacts the top of the movable sleeve 205e. One side of the stabilizing block 205h is also inclined. The connecting rod 205a has a through groove corresponding to the stabilizing block 205h. The sixth spring 205i applies a pushing force to the stabilizing block 205h, allowing the stabilizing block 205h to reset after moving. The seventh spring 205k applies a pushing force to the fixed plate 205j. When the support sleeve 205c separates from the arc plate 205d, the connecting rod 205a can be moved to its initial position via the fixed plate 205j.

[0087] When the support platform 105 is tilted, the sensing ball 205b will drive the support sleeve 205c to move to the tilted side, and push the arc plate 205d in the corresponding direction to move. When the arc plate 205d moves, it will drive the push rod 205g to squeeze the movable sleeve 205e, causing the movable sleeve 205e to move downward, and causing the stabilizing block 205h to move through the through groove to the outside of the connecting rod 205a. At the same time, the arc plate 205d contacts the end of the connecting rod 205a and drives the connecting rod 205a to move, which in turn allows the connecting rod 205a to drive the threaded plate 202d to move. When the stabilizing block 205h and the fixed frame 202c are in contact... When the outer side contacts, the inclined surface of the stabilizing block 205h is squeezed by the fixed frame 202c and moves upward and enters the movable sleeve 205e. This allows the connecting rod 205a and the threaded plate 202d to continue moving. When the threaded plate 202d is in contact with the threaded rod 202b, the sixth spring 205i applies a pushing force to the stabilizing block 205h, causing the stabilizing block 205h to move downward and the straight side of the stabilizing block 205h to contact the inner wall of the fixed frame 202c. This locks the connecting rod 205a and the threaded plate 202d, making the threaded plate 202d and the threaded rod 202b rigidly connected and preventing them from separating.

[0088] In use, in this embodiment, the leveling component 200 is preferentially used to level the stabilizing component 100. When the support platform 105 is tilted, the sensing ball 205b will drive the support sleeve 205c to move to the tilted side and push the arc plate 205d in the corresponding direction to move. When the arc plate 205d moves, it will drive the push rod 205g to squeeze the movable sleeve 205e, causing the movable sleeve 205e to move downward and the stabilizing block 205h to move to the outside of the connecting rod 205a through the through groove. At the same time, the arc plate 205d contacts the end of the connecting rod 205a and drives the connecting rod 205a to move, which in turn allows the connecting rod 205a to drive the threaded plate 202d to move. When the stabilizing block 205h contacts the outside of the fixed frame 202c, the inclined surface of the stabilizing block 205h will move upward under the pressure of the fixed frame 202c and enter the movable sleeve 205e. This allows the connecting rod 205a and the threaded plate 202d to continue moving. When the threaded plate 202d is in contact with the threaded rod 202b, the sixth spring 205i applies a pushing force to the stabilizing block 205h, causing the stabilizing block 205h to move downward and the straight side of the stabilizing block 205h to contact the inner wall of the fixed frame 202c. This locks the connecting rod 205a and the threaded plate 202d, making the threaded plate 202d and the threaded rod 202b rigidly connected and preventing them from separating.

[0089] When the threaded plate 202d moves, it simultaneously drives the pressing block 204n to press the inclined surface of the force-bearing block 204o. Through the cooperation of the two, the pressing sleeve 204k moves upward, so that the top inclined surface of the pressing sleeve 204k presses the limiting plate 204d, thereby separating the limiting plate 204d from the threaded rod 202b. At the same time as the pressing sleeve 204k moves upward, it drives the annular plate 204m to press the stop block 204g, so that the stop block 204g enters the first chamber 200-4 and releases the restriction on the movable block 204c, thereby allowing the movable block 204c and the limiting plate 204d to move. When the movable block 204c moves, it drives the pressing rod 204j to press the inclined surface of the inner wall of the force-bearing groove 200-6, thereby separating the locking block 204h from the locking hole 200-7, thereby releasing the restriction on the movable block 204b, allowing the movable block 204b to slide in the annular groove 200-3.

[0090] When the compression sleeve 204k moves upward, it simultaneously drives the connecting plate 202u to move upward. When the connecting plate 202u moves upward, it pushes the bearing plate 202r and the push block 202s to move upward, so that the push block 202s presses against the side of the locking block 202p at an angle, thereby allowing the locking block 202p to engage with the locking groove 200-2. At this time, the motor 202l is started to drive the gear ring 202k to rotate, which in turn drives the second gear 202j to rotate. The second gear 202j drives the rotating sleeve 202m to rotate through the engagement of the locking block 202p and the locking groove 200-2. The rotating sleeve 202m drives the threaded rod 202b to rotate through the engagement of the first limiting block 202n and the limiting groove 200-1, causing the threaded rod 202b to move downward. This allows the threaded rod 202b to drive the moving rod 201 to move downward, thereby allowing the support platform 105 to be horizontally adjusted.

[0091] Once the support platform 105 is adjusted to a horizontal position, the induction ball 205b and the support sleeve 205c will move to their initial positions, releasing the restriction on the connecting rod 205a and allowing it to reset. This also separates the threaded plate 202d from the threaded rod 202b. At this point, when the motor 202l rotates, it cannot drive the threaded rod 202b to move up and down. The threaded rod 202b will then lock again, preventing the moving rod 201 from becoming loose. Furthermore, there is no need to stop the motor 202l. When the support platform 105 tilts, it can be leveled promptly. The cooperation between the stabilizing component 100 and the leveling component 200 makes wind turbine foundation pile construction more convenient and prevents multiple foundation piles from shifting during construction. This reduces construction difficulty and time costs, and improves construction efficiency.

[0092] In this embodiment, the above-described leveling mechanism can be used. Those skilled in the art can also set up a leveling mechanism as required, such as the one in Embodiment 2, where the steel cable and the hydraulic cylinder work together.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
