[0027] It should be pointed out that the following detailed descriptions are all illustrative and are intended to provide further descriptions of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0029] As Figures 1 to 6 shown, the prefabricated fan base device of this embodiment includes: a cushion layer 10, a casting layer 20, a base assembly 30, and a hoop assembly 40. The base assembly 30 includes a plurality of base structures, and the plurality of base structures are spliced into a circular base assembly 30. The base structure includes a sector base 31 and a precast beam 32, and the precast beam 32 is disposed on the sector base 31. The hoop assembly 40 includes a hoop structure 41 and an anchor bolt structure 42. The hoop structure 41 is disposed on the side of the base assembly 30 away from the casting layer 20, and the base assembly 30 and the hoop assembly 40 are connected by the anchor bolt structure 42. A first casting hole 100 is provided on the base assembly 30, and a second casting hole 200 is provided on the hoop structure 41.

[0030] Applying the technical solution of this embodiment, the cushion layer 10 provides a foundation for the prefabricated fan base device, and the casting layer 20 enables the cushion layer 10 and the base assembly 30 to be well combined. After the base assembly 30 is assembled, the hoop assembly 40 connects the base assembly 30 together. The hoop structure 41 is located on the side of the base assembly 30 away from the casting layer 20, so that both the upper part and the lower part of the base assembly 30 are connected together. Such a prefabricated fan base device has good integrity and a relatively firm structure. The technical solution of this embodiment effectively solves the problems of more materials used and higher handling costs in the existing fan base device.

[0031] It should be noted that it is possible for one sector base 31 to correspond to one precast beam 32, or two precast beams 32, or three precast beams 32. In this embodiment, one sector base 31 corresponds to two precast beams 32.

[0032] As Figure 1 、 Figure 3 、 Figure 4 and Figure 6As shown, the sector base 31 includes a bottom plate 311, a base column 312, and a rib beam 313. The base column 312 is located at the inner edge of the bottom plate 311, and the rib beam 313 is located in the middle of the bottom plate 311. Two precast beams 32 are located on the bottom plate 311 and on both sides of the rib beam 313. The bottom plate 311 plays a role in supporting the precast beams 32, and the base column 312, the rib beam 313, and the precast beams 32 are connected together. This makes the same sector base 31 more stable. The fan base device of this embodiment includes 10 sector bases 31, that is, the central angle of each sector base 31 is 36°. Actually, because there needs to be a gap between adjacent sector bases 31, the actual central angle of the sector base 31 is 32° to 34°. In this embodiment, one base structure corresponds to one sector base 31 and two precast beams 32. The rib beam 313 is located in the middle, and the two precast beams 32 are symmetrically arranged on both sides of the rib beam 313.

[0033] As Figure 3 shown, in the technical solution of this embodiment, the base column 312 has an anchor bolt hole that penetrates vertically up and down. The anchor bolt structure 42 passes through the anchor bolt hole. The lower end of the anchor bolt structure 42 is located in the pouring layer 20, and the upper end of the anchor bolt structure 42 is located on the upper side of the hoop assembly 40. The anchor bolt structure 42 can connect the sector base 31 to the foundation more tightly. Specifically, through pouring, the entire assembled fan base device forms a whole. It should be noted that the hoop structure 41 includes two semi-circular plate bodies, and each plate body has an anchor bolt hole. Such a structure is convenient for transportation. In this embodiment, in order to make the assembled fan base device better form an integral structure, the projection of the gap between the two plate bodies in the vertical direction is located on the rib beam 313.

[0034] As Figure 3As shown, in the technical solution of this embodiment, the first pouring hole 100 communicates with the side wall and the central position of the base column 312. The first pouring hole 100 includes a first pouring inlet hole and a first pouring outlet hole. In the direction from the outside to the inside of the base column 312, the axis of the first pouring inlet hole is inclined downward. This facilitates the smooth entry of fluids such as lime (mortar) during pouring into the predetermined position under the action of gravity. In the technical solution of this embodiment, the inclination angle of the axis of the first pouring inlet hole is between 30° and 78°, which can not only ensure the smooth entry of fluids such as lime, but also not damage too much of the structure and strength of the base column 312. Fluids flow in through the first pouring inlet hole, and gas is discharged through the first pouring outlet hole. Both the first pouring inlet hole and the first pouring outlet hole are multiple, and the first pouring inlet hole and the first pouring outlet hole are arranged in pairs. Multiple first pouring inlet holes are arranged along the circumferential direction of the base column 312, and multiple rows of first pouring inlet holes are arranged vertically. In this embodiment, two rows of first pouring inlet holes are arranged vertically. The inlet of the first pouring inlet hole in the first row is located at the connection between the bottom plate 311 and the base column 312, and the outlet of the first pouring inlet hole in the first row is lower than the upper surface of the bottom plate 311, which is to better and more evenly flow fluids such as lime into the pouring layer 20. The first pouring inlet hole in the second row is located at 2 / 3 of the height of the base column 312, which facilitates the filling of lime in the assembled fan base device, and the space in the upper part is completed through the second pouring hole 200.

[0035] As Figure 3 shown, in the technical solution of this embodiment, the cushion layer 10 includes a recessed section. The diameter of the recessed section is larger than the diameter surrounded by the multiple anchor bolt holes and smaller than the outer circle diameter surrounded by the multiple base columns 312. The projection of the anchor bolt structure 42 in the vertical direction is located within the recessed section, so that the fixing effect of the anchor bolt structure 42 is better. It should be noted that the recessed section is a circle centered on the center of the assembled fan base device. The diameter of the outer ring outside the recessed section is 2.5 to 4.5 times the diameter of the recessed section.

[0036] In the technical solution of this embodiment, the bottom plate 311 has a positioning groove, the precast beam 32 has a positioning protrusion adapted to the positioning groove, and the side walls of the rib beam 313 and the precast beam 32 both have reinforcement grooves. The positioning groove facilitates the positioning and installation of the precast beam 32, and the reinforcement groove makes it more difficult for the precast beam 32 to break away from the fan-shaped base 31. It should be noted that the area of the reinforcement groove accounts for 1 / 4 of the area of the corresponding side surface, the depth is 1 / 3 of the wall thickness of the corresponding surface, the side wall of the reinforcement groove is 40 mm deep, and the reinforcement groove has a matching groove with a width half of the width of the side wall of the reinforcement groove, and the matching groove starts from the bottom of the reinforcement groove. The length of the matching groove is 1 / 3 of the length of the reinforcement groove. The combined action of the reinforcement groove and the matching groove enables the precast beam 32 and the rib beam 313 to achieve multi-directional limit fixation, and this limit is achieved through the setting of their own structures. Such a structure makes the base assembly 30 more compact.

[0037] As Figure 2 , Figure 4 and Figure 6 shown, in the technical solution of this embodiment, the prefabricated fan base device further includes a plurality of connection components 50, and adjacent base structures are connected by the plurality of connection components 50. The arrangement of the connection components 50 makes the connection between each prefabricated body more firm.

[0038] As Figure 2 , Figure 4 and Figure 6 shown, in the technical solution of this embodiment, the connection component 50 includes a U-shaped rib and a U-shaped rib connector. The U-shaped rib is connected to the base structure, and the U-shaped ribs on different base structures are connected by the U-shaped rib connector. The arrangement of the U-shaped rib facilitates connection. Specifically, the opening of the U-shaped rib faces the inside of the precast beam 32 and the foundation column 312, and through pouring, the U-shaped rib and the precast beam 32 and the foundation column 312 are poured into one body. The arc part of the U-shaped rib is exposed outside. The U-shaped ribs on two opposite faces of two adjacent precast beams 32 and foundation columns 312 appear in pairs and are staggered. These two U-shaped ribs are connected by the U-shaped rib connector. The U-shaped rib connector includes two downward steel plates and four bolts. The two steel plates are respectively located on the opposite sides of the two U-shaped ribs, and the four bolts are respectively located inside the U-shaped ribs.

[0039] According to another aspect of the present application, there is also provided a wind power generation device. The wind power generation device includes a prefabricated fan base device and a fan connected to the prefabricated fan base device. The prefabricated fan base device is the above-mentioned prefabricated fan base device. The base of the wind power generation device of the present application is convenient for transportation and installation.

[0040] According to another aspect of the present application, there is also provided an installation method for a fan base. The fan base is the above-mentioned fan base. The installation method includes the following steps: S10 Prefabricate the prefabricated fan base device. S20 Make the cushion layer 10, and splice and install the prefabricated fan base device. S30 Carry out the pouring work on the installed prefabricated fan base device so that the prefabricated fan base device forms an integral body.

[0041] As can be seen from the above, with reference to Figure 1 - Figure 6 , the gaps between the fan bases of this embodiment are cooperatively connected into a unified whole through pouring, the hoop assembly 40 and the connection component 50. It can improve the overall strength of the prefabricated foundation, ensure the concentricity of the prefabricated foundation assembly and improve the assembly efficiency.

[0042] The cushion layer 10 is located at the bottom of the assembled fan base device. The cushion layer 10 is of a circular structure as a whole. After the cushion layer 10 is poured, the upper part is a circular foundation assembled by a plurality of base components 30 along the circumferential direction. The base structure is of a fan-shaped structure. The bottom is a bottom plate 311, and the bottom plate 311 is of a fan-shaped structure. The upper part of the bottom plate 311 includes rib beams 313. The rib beams are perpendicular to the bottom plate 311 and have a rectangular cross-section. The other end of the rib beam is connected to the base column 312. The base column 312 is arranged on the side with a smaller area of the bottom plate 311. One end is connected to the bottom plate 311, and the other end extends upward. The cross-section shape of the base column 312 is fan-shaped, and the overall direction is consistent with the fan-shaped direction of the bottom plate 311. The base columns 312 are assembled in a circumferential direction into a cylindrical shape to form the support structure of the fan foundation. The shapes and sizes of the base components are exactly the same, and there are certain gaps between the base components. PVC casings are embedded in the base columns and arranged in a circular array.

[0043] It can be understood that with reference to Figure 2 and Figure 3 , the hoop structure 41 is of a circular ring shape as a whole and is composed of two identical semi-cylindrical bodies. Figure 2 is the cross-section of the semi-cylindrical body and is rectangular. The lower side of the hoop structure 41 in the vertical direction is the base column 312, and the upper side is the anchor bolt structure 42. The hoop structure 41 is provided with U-shaped steel bars, and PVC casings are embedded and arranged in a double row in a circular array.

[0044] It can be understood that the anchor bolt structure 42 includes components such as an upper anchor plate, a lower anchor plate, and anchor bolts. Specifically, the number of lower anchor plates is the same as that of the base components 30, and they are all factory prefabricated parts. There are two upper anchor plates in total, which are assembled into a circular ring shape as a whole. One is semi-circular in shape, and the structural form is the same as that of the hoop structure 41. It is located above the hoop structure 41. Both the upper anchor plate and the lower anchor plate are embedded with PVC casings.

[0045] It can be understood that with reference to Figure 5 , the assembled fan base device of this embodiment further includes a detection component 60, which is composed of a cross plate 62, a vertical plate 63, a bolt 64, and a vertical rod 61. The detection component 60 is a factory prefabricated part and is assembled by splicing two semi-circular shapes with the same structure and size. The detection component 60 is located on the poured cushion layer and is an auxiliary component for assembling the base components 30. The concentricity of the assembly of the base components 30 is ensured through the vertical rod 61, further ensuring the overall strength of the foundation of the base components 30 and improving the stability of the fan foundation.

[0046] Specifically, the bottom plate 311 and the cushion layer 10 are connected by grouting material. There are gaps between any two base components 30, and a certain number of key grooves are arranged at the splicing joints. The base components 30 are connected into a whole through grouting material and post-cast strips. The post-cast strip ( Figure 2The outermost layer) fastens each base assembly 30 together to prevent loosening and misalignment between the base assemblies 30; a gap is left between the base column 312 and the bottom, and a certain number of key slots are arranged at the joints. It can be understood that, referring to Figure 3 The hoop structure 41 is connected to the base assembly 30 through the anchor structure 42 and grouting material. The hoop structure 41 and the upper anchor plate are connected through grouting material. The anchor bolts in the anchor structure 42 pass through the upper anchor plate, the hoop structure 41, the base column 312 and the PVC sleeve reserved for the lower anchor plate from top to bottom, and are tightened and connected by threaded fasteners. The outer side of the upper part of the base column 312 is circumferentially tied with hoop steel bars and a circle of concrete is cast in place to improve the integrity of the prefabricated foundation.

[0047] This embodiment provides a method for installing an assembled fan base device:

[0048] The foundation pit is dug to the design elevation of the base and cleaned before the pit is inspected. After passing the inspection, the foundation engineering construction is carried out. Before the construction of the cushion layer 10, the base debris is cleaned to make the base flat and firm.

[0049] The lower cushion layer of the embedded detection assembly 60 is poured, and the cushion layer 10 must be poured in one go. Before installing the detection assembly 60, first conduct a trial assembly. Once the trial assembly is confirmed to be correct, use the vertical pole 61 to install and level the detection assembly 60. The detection assembly 60 consists of two pieces connected by a connecting plate. After the detection assembly 60 is assembled, check the level of the detection assembly 60. After the foundation detection assembly 60 is installed and leveled, re-check the level of the detection assembly 60. Once confirmed to be correct, the side walls of the foundation pit for the detection assembly 60 and the upper cushion layer 10 of the foundation are poured.

[0050] After the foundation cushion layer 10 meets the required strength, the foundation inspection assembly 60 is laid out and the compartment lines are set. A total station is used to determine the foundation center. The corner points of the single-piece base assembly 30 are set out on the cushion layer 10 to complete the compartment positioning lines. Height control blocks are placed in the compartments at the bottom of the foundation, and all control blocks should be at the same horizontal elevation. The mortar is laid according to the laid-out compartment positioning lines. The mortar should be thoroughly stirred to reduce floating slurry.

[0051] The base assembly 30 is hoisted. Specifically, after hoisting, debris at the bottom of the component is cleared to ensure that the component falls vertically and steadily to avoid collision and tilting, and to avoid large adjustments to the component. The hoisted components are assembled in sequence. After the base assembly 30 is in place, the hydraulic jack and the detection assembly 60 are used to assemble and fine-tune the position of the component to ensure the position of the anchor holes of adjacent components and control the concentricity of the assembly of each base assembly 30.

[0052] After all base components 30 are assembled, reinforcement is inserted into the joints. The reinforcement of the joints of the bottom plate 311 is allowed to be divided into two sections at most, which are staggered and overlapped and tied.

[0053] After the reinforcement of the base assembly 30 is tied, the foundation hoop structure 41 is installed. Specifically, the grouting seal is placed and the sealing strip is applied. Then, the hoop structure 41 is hoisted. After hoisting, the anchor bolt structure 42 is installed. Anchor bolts are inserted using an anchor bolt auxiliary tool. The anchor bolt tool is used to calibrate each inner and outer anchor bolt to improve the longitudinal accuracy of anchor insertion. The grouting layer is then sealed. After the anchor bolt assembly is installed, concrete is poured into the foundation pit at the detection assembly 60. After pouring, the surface is smoothed.

[0054] Each joint of the base assembly 30 is sealed with a template. A dedicated mold or wooden mold can be used to seal the joint, leaving no gaps. After the template is sealed, the foundation base plate 311 is grouted. Specifically, grouting is performed from the center hole of the compartment. The other grouting holes in the compartment are observed. If grout overflows from the grouting hole, the grouting hole is blocked with a full grout plug. The remaining grouting holes are continuously observed until all compartments are grouted.

[0055] After grouting the foundation slab 311, the vertical joints of the foundation columns 312 were grouted using the "grouting method" in two stages. The foundation columns 312 were then reinforced with steel and then post-cast strips were constructed to complete the concrete pouring of the circumferential seams of the foundation columns 312 and the joints of the slab 311.

[0056] After the circumferential pouring of the base assembly 30 is completed, the upper anchor plate is installed and grouting is carried out. Specifically, the grouting area is first roughened, the upper anchor plate is re-measured and leveled, and the grouting operation is continued. When the upper anchor plate grouting is completed, the lightning protection grounding facilities are installed.

[0057] Finally, the anchor bolts are installed and tensioned. Specifically, this tensioning process can be divided into two phases. In the first phase, after the first tower section is hoisted, the anchor bolts are tensioned to 80% of the design value. In the second phase, after the nacelle and rotor are hoisted, the anchor bolts are tensioned to the design value. Tensioning begins with tensioning at eight locations diagonally, and only after this is complete can the anchor bolts be tensioned sequentially. After all anchor bolts are tensioned, they are treated with an anti-corrosion agent.

[0058] The assembled wind turbine base device, wind turbine power generation equipment and installation method of the present invention have reliable connections between prefabricated components, fast foundation construction and low environmental pollution. The combination of multiple grouting forms can effectively improve the overall grouting quality and efficiency of the prefabricated foundation. The coordination of the hoop structure and the post-casting belt connection improves the integrity of the prefabricated foundation, effectively solving the problem of the wind turbine base device in the prior art using more materials and higher transportation costs.
