Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation, and in particular relates to a base platform for a wind power tower and a reinforcement method thereof. Background Art

[0002] In the field of wind power generation, wind turbine towers, as the tower poles of wind power generation, mainly play a supporting role in wind turbines, and at the same time absorb the vibrations generated by the operation of wind turbines. Therefore, the stability of wind turbine towers is directly related to the safe operation of the power generation system.

[0003] In the prior art, a base platform is provided at the bottom of the wind turbine tower. The base platform is usually cast directly on the ground surface and fixed to the ground through bottom extension columns in contact with the foundation soil. The wind turbine tower is fixed to the surface of the base platform. However, this type of design has significant defects: when the foundation soil collapses due to changes in geological conditions, rain erosion or long-term vibration, the contact area between the extension column at the bottom of the base platform and the foundation is small, and the extension column is difficult to provide sufficient anti-overturning moment, causing the base to easily deviate or even tilt, seriously threatening the structural safety of the wind turbine tower. Summary of the invention

[0004] The object of the present invention is to provide a base platform for a wind power tower and a reinforcement method thereof, so as to solve the problem that the base platform has a small contact area with the foundation and is prone to deviation.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a base platform for a wind power tower includes: a base, a plug-in tube, a rotating rod, an extrusion plate, a top holding ring, a force applying block, a screw rod, a force receiving block and a screw-in tube; A through hole is arranged on the surface of the base, a plug-in tube is installed on one side of the base, a wind power tower is installed on the other side of the base, an opening is arranged on the surface of the plug-in tube, a rotating rod is arranged in the inner cavity of the plug-in tube, one end of the rotating rod passes through the through hole, and the other end is connected to the screw rod, an extrusion plate is arranged in the opening and slidably connected to the plug-in tube, a top holding ring is installed on the rotating rod and close to the pressure surface of the extrusion plate, a screw tube is arranged at the end of the inner cavity of the plug-in tube and connected to the screw rod, a force block is fixed at the connection between the screw rod and the rotating rod, and a force block is fixed at the end of the screw tube.

[0006] In some embodiments, a fixing ring is disposed at the center of the surface on the other side of the base, a wind turbine tower is mounted on the fixing ring, and a plurality of through holes are disposed on the surface of the base along the circumferential direction of the fixing ring.

[0007] In some embodiments, a plug hole is provided at one end of the rotating rod passing through the through hole, a plug rod is detachably provided in the plug hole, and a rotating joint is fixed on the plug rod.

[0008] In some embodiments, a sleeve ring is rotatably connected to the surface of the abutting ring, an arc-shaped rod is arranged on the surface of the sleeve ring, and a baffle is fixedly installed on the arc-shaped rod.

[0009] In some embodiments, a plurality of openings are arranged on the surface of the insertion pipe, a pressing plate is arranged in one or more of the openings, and a baffle is arranged on the inner side of the other openings where no pressing plate is installed.

[0010] In some embodiments, a limiting rod is arranged at the bottom of the baffle, a circular ring is arranged on the inner wall of the insertion pipe, the limiting rod is slidably arranged inside the circular ring, and the circular ring is located below the opening.

[0011] In some embodiments, a limiting plate is arranged on the inner wall of the insertion pipe, a plurality of flow holes are arranged on the surface of the limiting plate, and a rotating rod is rotatably inserted on the limiting plate.

[0012] In some embodiments, an L-shaped rod is fixedly arranged on the surface of the pressing plate, and the L-shaped rod is inserted into the pipe wall of the insertion pipe.

[0013] In a second aspect, a reinforcement method for a wind power tower barrel includes the following steps: Drive the rotating rod to rotate along a straight line direction through the screw thread engagement between the screw rod and the screw socket pipe. After the abutting ring descends with the rotating rod, it abuts against the end of the pressing plate, so that the other end of the pressing plate moves to the outside of the insertion pipe through the opening; meanwhile, after the force-applying block descends with the rotating rod, it abuts against the surface of the force-receiving block, and at this time, the screw socket pipe continues to rotate with the rotating rod; During the process of the screw socket pipe rotating with the rotating rod, the insertion pipe is synchronously driven to rotate with the rotating rod. After the insertion pipe drives the pressing plate to move and extrude the soil in the foundation to form an annular groove, concrete is poured into the interior of the insertion pipe. The concrete flows out through the opening and fills the annular groove. After the concrete is completely solidified, the reinforcement is completed.

[0014] In some embodiments, the following steps are further included: Rotate and connect a sleeve ring to the surface of the abutting ring, arrange an arc-shaped rod on the surface of the sleeve ring, and fixedly install a baffle on the arc-shaped rod; Arrange a limiting rod at the bottom of the baffle, arrange a circular ring on the inner wall of the insertion pipe, and slidably arrange the limiting rod inside the circular ring. The circular ring is located below the opening; Before driving the rotating rod to rotate, block the opening by arranging the baffle inside the opening through the insertion of the limiting rod into the circular ring; After driving the rotating rod to rotate, the baffle descends to the lower side of the bottom of the opening with the rotating rod through the limiting rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the extrusion plate is arranged within the opening and is slidably connected to the insertion pipe. The holding ring is mounted on the rotating rod and is located above the extrusion plate. The threaded pipe is arranged at the inner bottom of the insertion pipe and is connected to the screw rod. The force - applying block is fixed at the connection of the screw rod and the rotating rod, and the force - receiving block is fixed at the end of the threaded pipe. The rotating rod rotates and descends through the screwing of the screw rod and the threaded pipe. At this time, the holding ring holds the end of the extrusion plate, pushing the extrusion plate out of the opening. Meanwhile, when the force - applying block holds against the surface of the force - receiving block, the rotating rod drives the insertion pipe to rotate, and the insertion pipe drives the extrusion plate to move and extrude the soil to form an annular groove. Concrete can be poured into the groove. After the concrete solidifies, a solid concrete annular groove is formed, expanding the contact area between the base platform and the foundation, reducing the settlement and offset of the wind power tower during use, thus solving the problem of the small contact area between the base platform and the foundation and the easy occurrence of offset, and significantly improving the anti - settlement and anti - offset capabilities of the wind power tower under complex geological conditions.

[0016] Furthermore, a number of through - holes are arranged on the surface of the base along the circumferential direction of the fixed ring, and multiple insertion pipes can be inserted, evenly transferring the load of the tower barrel to the foundation through the insertion pipes, avoiding excessive local stress concentration.

[0017] Furthermore, a plug - in hole is arranged at one end of the rotating rod passing through the through - hole. A plug - in rod is detachably arranged in the plug - in hole, and a rotating joint is fixed on the plug - in rod. The plug - in rod is detachably arranged in the plug - in hole, facilitating component replacement and maintenance.

[0018] Furthermore, a sleeve ring is rotatably connected to the surface of the holding ring. An arc - shaped rod is arranged on the surface of the sleeve ring, and a baffle is fixedly installed on the arc - shaped rod. A limiting rod is arranged at the bottom of the baffle. A circular ring is arranged on the inner wall of the insertion pipe, and the limiting rod is slidably arranged inside the circular ring. The circular ring is located below the opening. The cooperation between the limiting rod and the circular ring can ensure the vertical movement of the baffle, avoiding the deviation of the moving direction of the baffle. In addition, the sleeve ring can rotate on the surface of the holding ring, and can offset the torque generated during the rotation process of the rotating rod through the rotational movement, avoiding the deviation of the baffle due to the rotation of the rotating rod, and ensuring that the rotational movement of the rotating rod and the vertical movement of the baffle do not interfere with each other.

[0019] Furthermore, an L - shaped rod is fixed on the surface of the extrusion plate, and the L - shaped rod is inserted into the pipe wall of the insertion pipe, which can prevent the extrusion plate from detaching, ensure the linear movement of the extrusion plate, and improve the extrusion effect.

[0027] Embodiment 1 This embodiment provides a base platform for a wind power tower barrel, including a base 1, an insertion pipe 4, a rotating rod 8, a pressing plate 17, a holding ring 19, a force-applying block 20, a screw rod 21, a stress block 22, and a screwed pipe 23; A through hole 3 is provided on the surface of the base 1. The insertion pipe 4 is installed at the bottom of the base 1. An opening 11 is provided on the surface of the insertion pipe 4.

[0028] As Figure 1 shown, a through hole 3 is formed on the surface of the base 1. A fixing ring 2 is fixed on the top of the base 1, and a wind power tower barrel is fixed on the top of the fixing ring 2.

[0029] Combined with Figure 1 As Figure 2 And Figure 3As shown, the insertion pipe 4 is inserted into the through hole 3. A rotating rod 8 is arranged inside the insertion pipe 4. A plug hole 7 is opened at the end of the rotating rod 8. A rotating joint 5 is arranged at the top of the rotating rod 8. A plug rod 6 is fixed at the bottom of the rotating joint 5. The other end of the rotating joint 5 is connected to a driving device. The driving device drives the rotating joint 5 to rotate. The plug rod 6 rotates along with the rotating rod 5. The plug rod 6 at the end of the rotating joint 5 is inserted into the plug hole 7 on the surface of the rotating rod 8. The rotating rod 8 rotates along with the rotating rod 5. After the rotating rod 8 rotates, the screw rod 21 is screwed into the inside of the screw pipe 23, causing the rotating rod 8 to descend inside the insertion pipe 4. The holding ring 19 on the surface of the rotating rod 8 descends along with the rotating rod 8.

[0030] As Figure 4 shown, a limiting plate 9 is fixed inside the insertion pipe 4. A circulation hole 10 is opened on the surface of the limiting plate 9. The rotating rod 8 is inserted into the inside of the limiting plate 9. The rotating rod 8 can rotate inside the limiting plate 9.

[0031] As Figures 5 to 7 shown, a screw rod 21 is arranged at the bottom of the rotating rod 8. A force - applying block 20 is fixed on the surface of the rotating rod 8. A screw pipe 23 is arranged inside the insertion pipe 4. A force - receiving block 22 is fixed at the end of the screw pipe 23; Four groups of openings 11 are arranged on the surface of the insertion pipe 4. An extrusion plate 17 is arranged in one of the openings 11. The holding ring 19 on the surface of the rotating rod 8 descends along with the rotating rod 8. The holding ring 19 abuts against the end of the extrusion plate 17, causing the extrusion plate 17 to extend out of the opening 11. Baffles 12 are arranged on the inner sides of the other three groups of openings 11. The baffles 12 block inside the openings 11 to prevent soil from entering the inside of the insertion pipe 4.

[0032] Multiple groups of holding rings 19 are fixed on the surface of the rotating rod 8. Each group of holding rings 19 is located above the corresponding opening 11 before the rotating rod 8 rotates. The holding ring 19 moves along with the rotating rod 8. A sleeved ring 18 is sleeved on the surface of the holding ring 19. The sleeved ring 18 can rotate on the surface of the holding ring 19. An arc - shaped rod 13 is fixed on the surface of the sleeved ring 18. The other end of the arc - shaped rod 13 is fixed with a baffle 12. The baffle 12 and the arc - shaped rod 13 move along with the rotating rod 8. A limiting rod 14 is fixed at the bottom of the baffle 12. A circular ring 15 is fixed inside the insertion pipe 4. The circular ring 15 is located below the corresponding opening 11. The limiting rod 14 is inserted into the inside of the circular ring 15. The limiting rod 14 can move up and down inside the circular ring 15; The baffle 12 is blocked inside the opening 11. A screw pipe 23 is fixed to the bottom inside the insertion pipe 4. Threads are provided on the inner wall of the screw pipe 23. A screw rod 21 is fixed to the bottom of the rotating rod 8. The screw rod 21 is screwed inside the screw pipe 23. Multiple stress blocks 22 are fixed to the top of the screw pipe 23. Multiple force - applying blocks 20 are fixed to the surface of the rotating rod 8. The force - applying blocks 20 rotate and move along with the rotating rod 8. After the force - applying blocks 20 descend along with the rotating rod 8, they abut against the surface of the stress blocks 22, causing the screw pipe 23 to rotate along with the rotating rod 8. Since the screw pipe 23 is fixed inside the insertion pipe 4, the insertion pipe 4 rotates along with the rotating rod 8. After the abutting ring 19 descends along with the rotating rod 8, it abuts against the end of the extrusion plate 17, causing the extrusion plate 17 to move in the opening 11. The extrusion plate 17 extends out from the inside of the insertion pipe 4 and rotates along with the insertion pipe 4. Openings 11 are provided on the surface of the insertion pipe 4. There are four groups of openings 11. An extrusion plate 17 is arranged in one of the openings 11. Two L - shaped rods 16 are fixed to the surface of the extrusion plate 17. The L - shaped rods 16 are inserted into the inside of the insertion pipe 4. The L - shaped rods 16 move along with the extrusion plate 17. The extrusion plate 17 can move in the opening 11.

[0033] The working principle of the base platform for a wind power tower barrel provided in the above - mentioned embodiment is as follows: A round hole is opened in the soil at the bottom of the base 1. One end of the insertion pipe 4 is inserted into the through - hole 3, and the other end of the insertion pipe 4 is inserted into the round hole. The wind power tower barrel is fixed to the surface of the fixed ring 2. The end of the rotating joint 5 is connected to a driving device. The driving device drives the rotating joint 5 to rotate. The insertion rod 6 at the end of the rotating joint 5 is inserted into the insertion hole 7 on the surface of the rotating rod 8. The rotating rod 8 rotates along with the rotating joint 5. After the rotating rod 8 rotates, the screw rod 21 is screwed into the inside of the screw pipe 23, causing the rotating rod 8 to descend inside the insertion pipe 4. The abutting ring 19 on the surface of the rotating rod 8 descends along with the rotating rod 8. The abutting ring 19 abuts against the end of the extrusion plate 17, causing the extrusion plate 17 to extend out from the opening 11. And there are four groups of openings 11. Baffles 12 are arranged inside the other three groups of openings 11. The initial position of the baffles 12 is to block inside the openings 11 to prevent soil from entering the inside of the insertion pipe 4. The sleeving ring 18 is located on the surface of the abutting ring 19. The sleeving ring 18 can rotate. The opening 11 is connected to the sleeving ring 18 through an arc - shaped rod 13. The baffle 12 descends along with the abutting ring 19. After the force - applying blocks 20 descend along with the rotating rod 8, they abut against the surface of the stress blocks 22, causing the rotating rod 8 to drive the insertion pipe 4 to rotate. After the insertion pipe 4 rotates, the extrusion plate 17 extrudes a circular groove in the soil. Concrete is poured into the inside of the insertion pipe 4. The concrete flows into the inside of the insertion pipe 4 from the flow - through holes 10 on the surface of the limiting plate 9 and flows out from the opening 11. The concrete flowing out from the opening 11 increases the contact area between the base 1 and the ground.

[0034] The base platform provided in this embodiment has the following advantages: First, by connecting the two ends of the insertion pipe to the round hole and the through hole at the bottom of the base respectively, and driving the screw to be screwed into the screw pipe by the rotating rod to achieve descent, the top holding ring accurately holds and extrudes the extrusion plate to extend, forming an annular groove in the foundation, significantly increasing the contact area between the base and the land, improving the uplift and anti-overturning capabilities of the base platform, and ensuring the long-term stability of the structure. Second, the baffle is initially positioned to block inside the opening, effectively preventing soil from entering the insertion pipe, ensuring the cleanliness of the construction environment and the normal operation of the equipment. Third, by arranging flow holes on the surface of the limiting plate, the concrete can smoothly flow into the insertion pipe and flow out from the opening, filling the annular groove, ensuring the uniform distribution and sufficient compaction of the concrete, and improving the reinforcement effect. Fourth, it is applicable to various geological conditions. By adjusting the descent amount of the rotating rod and the extension amount of the extrusion plate, it can flexibly cope with foundations in different situations.

[0035] Embodiment Two Based on the base platform provided in Embodiment One, this embodiment provides a reinforcement method for a wind power tower barrel, including the following steps: Drive the rotating rod 8 to rotate linearly through the threaded engagement between the screw 21 and the screw pipe 23 by the driving device. After the top holding ring 19 descends with the rotating rod 8, it holds against the end of the extrusion plate 17, causing the other end of the extrusion plate 17 to move outside the insertion pipe 4 through the opening 11; at the same time, after the force application block 20 descends with the rotating rod 8, it holds against the surface of the force receiving block 22, and at this time, the screw pipe 23 continues to rotate with the rotating rod 8; During the process of the screw pipe 23 rotating with the rotating rod 8, it synchronously drives the insertion pipe 4 to rotate with the rotating rod 8. After the insertion pipe 4 drives the extrusion plate 17 to move and extrude the soil in the foundation into an annular groove, concrete is poured into the inside of the insertion pipe 4. The concrete flows out through the opening 11 and fills the annular groove. After the concrete completely solidifies, the reinforcement is completed.

[0036] Before driving the rotating rod 8 to rotate, the baffle is arranged inside the opening 11 to block the opening 11 by inserting the limiting rod 14 into the circular ring 15; After driving the rotating rod 8 to rotate, the baffle 12 descends with the rotating rod to below the bottom side of the opening 11 through the limiting rod 14.

[0037] The method provided in this embodiment ensures the descent displacement of the top holding ring through the precise cooperation between the screw and the screw pipe, ensuring that the extrusion plate contacts the foundation with a constant pressure, avoiding size deviation of the annular groove caused by pressure fluctuations. At the same time, after the force application block and the force receiving block hold against each other, a torque transmission path is automatically established when the screw pipe continues to rotate, stabilizing the rotation speed of the insertion pipe within a preset range and ensuring the quality of the groove formation. During the concrete pouring, the baffle automatically retracts below the opening through the sliding fit between the limiting rod and the circular ring, forming an unobstructed pouring channel.

[0038] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
