Technical fields:

[0001] This invention relates to the field of wind turbine foundation ring construction technology, specifically a wind turbine foundation ring structure. Background technology:

[0002] The base ring is located between the seat ring and the straight tapered tube, serving as a connection and support, and is the reference component for turbine installation.

[0003] Common methods used in the reinforcement of annular wind turbine foundations include grouting reinforcement, applying circumferential prestress to increase the cross-section, installing steel plates around the foundation ring, and adding horizontal reinforcement or anchor bolts. Currently, annular wind turbine foundations are often densely reinforced and involve large-volume concrete construction. The design requires that the concrete be poured in one go, which places high demands on the quality of concrete construction. However, on-site construction personnel often have a weak sense of quality, which can easily lead to insufficient compaction of the concrete. During the vibration process, there is a high risk of missed vibration and uneven compaction, resulting in serious quality problems such as substandard concrete strength. Summary of the Invention:

[0004] The purpose of this invention is to provide a wind turbine foundation ring structure to solve the problem mentioned in the background art that wind turbine foundation rings are prone to uneven compaction during concrete pouring.

[0012] Preferably, the vibrating rod has a hollow structure and a fixing rod is provided inside the vibrating rod.

[0013] Preferably, a vibration motor is fixedly connected to the fixed rod, and springs are connected to both sides of the vibration motor.

[0014] Preferably, a vibrating block is provided on one side of the spring, and the vibrating block is made of an iron block wrapped with rubber.

[0015] Preferably, the vibrating blocks are longitudinally and equally spaced on the left and right sides of the inner wall of the vibrating rod, and the vibrating blocks are movably connected to the vibrating rod.

[0016] Advantages of this invention:

Detailed implementation method:

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-5 The present invention provides a technical solution: a wind turbine foundation ring structure, including a steel reinforcement foundation 1, a foundation ring 2 fixedly connected to the top side of the steel reinforcement foundation 1, and a vibrating assembly 3 provided on the outer wall of the foundation ring 2;

[0029] The vibratory assembly 3 includes a first track 31 and a second track 32. The first track 31 is composed of multiple splicing rods 38, with at least two splicing rods 38. (See instruction manual attached.) Figure 2 The middle part is composed of four splicing rods 38. One side of the splicing rod 38 has a groove, the bottom side of the splicing rod 38 has an opening, and the other side is provided with a locking block 311. The top side of the splicing rod 38 is fixedly connected to the locking block 311. The splicing rod 38 has an arc-shaped structure. This structure can be spliced ​​and disassembled to facilitate construction and transportation, and can be used multiple times.

[0030] Furthermore, the first track 31 and the second track 32 have the same structure, and the first track 31 and the second track 32 form a splicing structure; this structure, by setting the first track 31 and the second track 32 in a splicing combination, allows the first track 31 and the second track 32 to be disassembled at any time without affecting the subsequent hoisting work of the foundation ring 2.

[0031] Furthermore, a slider 39 is inserted into the second track 32. The second track 32 and the slider 39 are structurally matched and slidably connected. The top side of the slider 39 is connected to the fixed frame 37. This structure allows the fixed frame 37 to be circumferentially slidable to adjust its position, thereby facilitating the operation of the vibrator 35 in different areas.

[0032] The first track 31 and the second track 32 are respectively set on the left and right sides of the foundation ring 2, enclosing the foundation ring 2. The first track 31 and the second track 32 are combined to form a ring structure. A fixed frame 37 is movably connected to the second track 32. A fixed plate 33 and a limiting plate 36 are provided on the outer wall of the fixed frame 37. The fixed frame 37 is fixedly connected to the fixed plate 33 and the limiting plate 36. The fixed plate 33 is located on the top side of the limiting plate 36. A flexible hose 34 is provided at the bottom of the fixed plate 33. A vibrating rod 35 is connected to the lower end of the flexible hose 34. This structure, by setting the flexible hose 34 to connect the vibrating rod 35, facilitates the pulling and adjustment of the angle and position of the vibrating rod 35.

[0033] Furthermore, a "U"-shaped notch is provided on one side of the limiting plate 36, and a "U"-shaped notch is provided on the right side of the limiting plate 36. A vibrating rod 35 is inserted into the notch, and a limiting rod 310 is provided on the inner wall of the notch. The limiting plate 36 is fixedly connected to the limiting rod 310, and the limiting rod 310 is located at one end of the vibrating rod 35. The limiting rod 310 is located at the front end of the vibrating rod 35. This structure, by setting the limiting rod 310 and the limiting plate 36, can insert the vibrating rod 35 into the limiting plate 36 and limit the vibrating rod 35, making it convenient to store the vibrating rod 35.

[0034] The fixed frame 37 is equipped with at least two vibrating rods 35, and there are ten vibrating rods 35 in total. This device is assembled into a ring structure by splicing the first track 31 and the second track 32 and fits around the outside of the foundation ring 2. The fixed frame 37 is slidably set on the first track 31 and the second track 32, and multiple vibrating rods 35 are set on the fixed frame 37. This allows multiple vibrating rods 35 to be inserted into the concrete at the same time for vibration work, avoiding the phenomenon of missing the vibration area. At the same time, the position of the fixed frame 37 can be moved in a ring to facilitate the adjustment of the position of the vibrating rods 35 and improve the efficiency of vibration work.

[0035] Furthermore, the vibrating rod 35 has a hollow structure, and a fixing rod 314 is provided inside the vibrating rod 35, which is fixedly connected to the fixing rod 314. This structure uses the fixing rod 314 to fix the vibration motor 315. The vibration motor 315 is fixedly connected to the fixing rod 314, and springs 313 are connected to both sides of the vibration motor 315, which is fixedly connected to the springs 313. This structure, by connecting the springs 313 to the vibration motor 315, can transmit the vibration generated by the vibration motor 315 to the springs 313. 13; A vibrating block 312 is provided on one side of the spring 313, and the vibrating block 312 is fixedly connected to the left side of the spring 313. The vibrating block 312 is made of an iron block wrapped with rubber. This structure can transmit vibration to the vibrating block 312 through the spring 313. The vibrating blocks 312 are distributed longitudinally at equal intervals on the left and right sides of the inner wall of the vibrating rod 35, and the vibrating blocks 312 are movably connected to the vibrating rod 35. This structure ensures the uniformity of vibration of the vibrating rod 35 by setting the vibrating block 312, the spring 313 and the vibration motor 315 inside the vibrating rod 35.

[0036] Working principle: When using this wind turbine foundation ring structure, first take out an appropriate number of splicing rods 38, and splice the first track 31 and the second track 32 on the left and right sides of the foundation ring 2 respectively. When splicing, simply insert the locking block 311 of one splicing rod 38 into the groove of the other splicing rod 38. After splicing the first track 31 and the second track 32, fix the first track 31 and the second track 32 with bolts. After fixing, the concrete can be vibrated. Before vibration, remove the vibrator 35 from inside the limiting plate 36. When removing the vibrator, press the limiting rod 310 inside the limiting plate 36 to allow the vibrator 35 to smoothly detach from the limiting plate 36. After removing the vibrator 35, insert it back into the concrete. Then start the vibration motor 315. The vibration motor 315 generates vibration, which is transmitted to the vibration block 312 through the spring 313, thereby causing the outer wall of the vibrator 35 to vibrate as well, thus vibrating the concrete. At the same time, the vibration on the surface of the vibrator 35 also prevents concrete from sticking to the surface of the vibrator 35 and making it difficult to clean.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
