[0071] The embodiments of this application are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0072] The tower operation platform 10 and the wind turbine tower provided according to embodiments of this application are described below with reference to Figures 1-7.

[0073] As shown in Figures 1-7, the tower operation platform 10 provided in this embodiment of the application includes a splicing module 1 and a post-pouring strip 2.

[0074] The splicing module 1 is made of cast concrete, and there are at least two splicing modules 1 connected together. The post-cast strip 2 is made of cast concrete and is cast and connected between two adjacent splicing modules 1.

[0075] As shown in Figures 1-7, the tower operating platform 10 is horizontally installed inside the tower body 20 and is used by operators to install and maintain the equipment.

[0076] The tower operating platform 10 optionally includes two splicing modules 1, each made of cast concrete. Each splicing module 1 can be a semi-circular plate with an arc-shaped end and a flat end in the horizontal direction. The flat ends of the two splicing modules 1 are arranged opposite each other. A post-cast strip 2 is cast and connected between the flat ends of the two splicing modules 1, allowing the two splicing modules 1 to be spliced ​​together and forming a circular concrete platform body. In other words, the concrete platform body includes, optionally, two splicing modules 1 and a post-cast strip 2. The post-cast strip 2 is also made of cast concrete to enable the two splicing modules 1 to be cast and connected.

[0077] It is understood that the tower operating platform is not limited to including two semi-circular splicing modules. In other embodiments, the tower operating platform includes multiple fan-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform.

[0078] It is understood that the splicing modules are not limited to including arc-shaped ends and planar ends. In other embodiments, the tower operating platform includes multiple triangular splicing modules, which are sequentially connected along the circumference of the tower operating platform to form a polygonal concrete platform body. In other words, the triangular splicing module has three planar ends, two of which are arranged along the circumference of the tower operating platform and are used to connect other splicing modules on the corresponding side, and the remaining planar end is connected between the two planar ends to form the outer circumferential surface of the polygonal concrete platform body.

[0079] The tower operating platform provided in this application embodiment has multiple splicing modules made of concrete. These modules are connected to adjacent splicing modules by post-casting strips made of concrete, so that multiple splicing modules can be spliced ​​together. The production is simple and fast, with a short processing cycle to ensure delivery time and low production cost. At the same time, the tower operating platform has a simple structure and will not lose parts during transportation and stacking.

[0080] As shown in Figures 1 and 2, the end face of the splicing module 1 used to connect the post-pouring strip 2 has multiple protruding connecting ribs 11. In two adjacent splicing modules 1, the multiple connecting ribs 11 of one splicing module 1 are connected to the multiple connecting ribs 11 of the other splicing module 1 in a one-to-one overlapping manner and are poured into the post-pouring strip 2.

[0081] Specifically, the concrete interior of the splicing module 1 contains a steel mesh with multiple connecting bars 11. These connecting bars 11 extend from the planar end of the splicing module 1 and are spaced apart along the length of the planar end. The connecting bars 11 of one splicing module 1 are lapped together with those of another splicing module 1 in a one-to-one correspondence. The two lapped connecting bars 11 can be further connected by binding wire. Concrete is poured onto the lapped connecting bars 11 to form a post-cast strip 2. In other words, the concrete interior of the splicing module 1 contains multiple lapped connecting bars 11, thereby ensuring the strength of the tower operating platform 10.

[0082] As shown in Figures 1-3, the splicing module 1 includes a splicing plate 12 and a splicing support beam 13. The splicing plate 12 is set horizontally, and the splicing support beam 13 is located at the bottom of the splicing plate 12. Both the splicing plate 12 and the splicing support beam 13 are made of concrete and are connected as a whole.

[0083] Both the splicing plate 12 and the splicing support beam 13 have steel mesh, which has multiple connecting bars 11. The portion of the splicing plate 12 located at the planar end has a portion of the connecting bars 11 extending outwards, and the portion of the splicing support beam 13 located at the planar end has another portion of the connecting bars 11 extending outwards. In two adjacent splicing modules 1, the connecting bars 11 of the splicing plate 12 of one splicing module 1 are connected one-to-one with the connecting bars 11 of the splicing plate 12 of the other splicing module 1, and the connecting bars 11 of the splicing support beam 13 of one splicing module 1 are connected one-to-one with the connecting bars 11 of the splicing support beam 13 of the other splicing module 1.

[0084] The post-cast strip 2 connects the splicing plates 12 of two adjacent splicing modules 1 and the splicing support beams 13 of two adjacent splicing modules 1. Specifically, the post-cast strip 2 includes an integrally connected strip portion and a protrusion portion. The strip portion extends horizontally and is cast between the two splicing plates 12. The connecting ribs 11 extending from the two splicing plates 12 are located inside the strip portion. The bottom of the strip portion has a protrusion portion, which is cast between the two splicing support beams 13. The connecting ribs 11 extending from the two splicing support beams 13 are located inside the protrusion portion.

[0085] The splicing support beam 13 supports the splicing plate 12, ensuring the strength of the splicing plate 12, while reducing the thickness and weight of the splicing module 1 and reducing the amount of concrete used. The post-pouring strip 2 connects the splicing plate 12 and the splicing support beam 13 to ensure the connection stability between the splicing modules 1 and the strength of the tower operating platform 10.

[0086] As shown in Figures 1-3, the splicing support beam 13 includes a main beam 131 and a support beam 132. At least one end of the support beam 132 is connected to the main beam 131, and the support beam 132 is set at an angle to the main beam 131. Several main beams 131 and at least two support beams 132 are staggered and connected. At least some of the support beams 132 have free ends forming connection parts 133. In two adjacent splicing modules 1, the connection parts 133 of one splicing module 1 are set one-to-one with the connection parts 133 of the other splicing module 1, and are connected by casting through the post-pouring strip 2.

[0087] Specifically, the length direction of the main beam 131 is orthogonal to the length direction of the support beam 132. The length direction of the main beam 131 is parallel to the length direction of the planar end. At least two support beams 132 are provided on both sides of the width direction of the main beam 131. The at least two support beams 132 on the same side are arranged at intervals along the length direction of the main beam 131. Optionally, three support beams 132 are provided on the side of the main beam 131 facing the planar end, and two support beams 132 are provided on the side of the main beam 131 away from the planar end. Along the length direction of the main beam 131, the support beams 132 on the side away from the planar end are located between two adjacent support beams 132 facing the planar end.

[0088] The support beam 132 has a connecting end and a free end that are arranged opposite to each other along the length direction. The connecting end is connected to the main beam 131. Among the three support beams 132 located on the side of the main beam 131 facing the plane end, the free end of the support beam 132 is located at the plane end of the splicing module 1 to form a connecting part 133. Therefore, the plane end of the splicing module 1 has three connecting parts 133 arranged at intervals. The connecting part 133 has multiple protruding connecting ribs 11. The three connecting parts 133 of one splicing module 1 are arranged one-to-one with the three connecting parts 133 of another splicing module 1 and are connected by casting through the post-pouring strip 2.

[0089] It is understood that the arrangement of the main beam and the support beam is not limited to that shown in Figure 3. In other embodiments, the tower operating platform includes multiple fan-shaped splicing modules. The multiple fan-shaped splicing modules are connected sequentially along the circumference of the tower operating platform. The splicing support beam of the splicing module is fishbone shaped. The main beam extends radially along the tower operating platform. Multiple support beams are provided on both sides of the width of the main beam. Multiple support beams on the same side are arranged at intervals along the length of the main beam. The support beams are arranged at an acute angle to the main beam. In two splicing modules that are adjacent in the circumference, multiple support beams on one side of the main beam of one splicing module are relatively close to and corresponding to multiple support beams on the other side of the main beam of the other splicing module, and are connected by post-casting strips.

[0090] As shown in Figures 1-3, the main body of the concrete platform is provided with elevator holes 4 and cable holes 5 arranged at intervals. The elevator holes 4 penetrate the splicing plate 12 of the two splicing modules 1 in the vertical direction. Specifically, the elevator hole 4 includes two connected sub-holes. The two sub-holes are provided one-to-one on the splicing plate 12 of the two splicing modules 1 and are located at the plane end of the splicing module 1. The post-pouring strip 2 is divided into two intervals by the elevator hole 4.

[0091] The cable hole 5 is located on the splicing plate 12 of one of the splicing modules 1 and passes through the splicing plate 12 in a vertical direction.

[0092] Both elevator hole 4 and cable hole 5 are offset from main beam 131 and support beam 132.

[0093] The tower operating platform 10 also includes a fence 3, which is set on the concrete platform body, specifically on the splicing plate 12 of the two splicing modules 1. The fence 3 is set around the elevator hole 4 in the vertical direction.

[0094] The elevator opening 4 and the fence 3 allow the elevator and elevator track to pass vertically. The fence 3 also separates the space it surrounds from the working space on the splicing plate 12, protecting the operators on the splicing plate 12 from accidental collisions with the operating elevator or accidental falls through the elevator opening 4. Optionally, the fence 3 is equipped with an openable and closable gate for operator passage.

[0095] Cable hole 5 is used for cables to pass through in a vertical direction. Optionally, the tower operating platform 10 also includes an orifice plate 7, which covers the cable hole 5 and has through holes for cables to pass through. This prevents operators on the splicing plate 12 from accidentally falling through the cable hole 5. During operation, the orifice plate 7 is prohibited from being stepped on and is marked with signs to avoid safety hazards.

[0096] Both the fence 3 and the perforated plate 7 can be made of steel and are installed on the splicing plate 12 by means of connectors such as bolts.

[0097] It should be noted that the elevator hole is not limited to being located on two splicing plates simultaneously. In other embodiments, the elevator hole can be located on the splicing plate of one splicing module or on the splicing plate of multiple splicing modules. For example, the tower operating platform 10 includes multiple fan-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform 10. The elevator hole is located at the splicing center of the multiple fan-shaped splicing modules. In other words, the elevator hole is located at the center of the concrete platform body.

[0098] It should be noted that the cable holes are not limited to being located on the splicing plate of one splicing module. In other embodiments, the cable holes are also located on the splicing plates of two splicing modules. The cable holes and elevator holes are arranged at intervals along the length of the post-cast strip, and the post-cast strip is divided into three segments.

[0099] Furthermore, the splicing module 1 is also equipped with a mounting bracket or mounting rail for mounting and accommodating tools and equipment, such as fire extinguishers. Both the mounting bracket and mounting rail can be made of steel and are mounted on the splicing plate 12 using connectors such as bolts.

[0100] As shown in Figures 2-5, the tower operating platform 10 also includes a leveling device 6. The leveling device 6 is located on the splicing plate 12 and / or the splicing support beam 13. There are multiple leveling devices 6, which are located at the outer periphery of at least two splicing modules 1 and are arranged at intervals along the circumference of the splicing assembly.

[0101] Specifically, there are at least three leveling devices 6, which are located at the outer periphery of the concrete platform body and arranged at intervals along the circumference of the concrete platform body. The leveling devices 6 are located at the arc-shaped ends of the corresponding splicing modules 1. The leveling devices 6 can be located on the splicing plate 12, on the splicing support beam 13, or on both the splicing plate 12 and the splicing support beam 13.

[0102] Optionally, the leveling device 6 is located inside the arc-shaped end of the corresponding splicing module 1 and can extend from the bottom of the arc-shaped end of the splicing module 1. In other words, the leveling device 6 is located inside the outer periphery of the concrete platform body and can extend from the bottom of the outer periphery of the concrete platform body.

[0103] Optionally, each splicing module 1 is provided with several leveling devices 6 at its curved end.

[0104] The leveling device 6 is used to level the concrete platform body to prevent the tower operating platform 10 from swaying vertically within the tower body 20.

[0105] To ensure the stability of the tower operating platform 10 and prevent it from swaying due to factors such as operator movement, the leveling device 6 is configured with at least three units to form a stable support.

[0106] It is understood that the leveling device is not limited to being located inside the arc-shaped end of the splicing module. In other embodiments, the leveling device is located on the arc surface of the arc-shaped end of the splicing module. In other words, the leveling device is located on the outer peripheral surface of the outer peripheral end of the concrete platform body. In other words, the leveling device is located on the side wall surface of the concrete platform body along the horizontal direction.

[0107] It is understood that, not limited to each splicing module being equipped with a leveling device, in some other embodiments, the tower operating platform includes three or more sector-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform. In this case, some splicing modules are not equipped with leveling devices.

[0108] As shown in Figures 1-5, at least one end of the main beam 131 forms a mounting portion 134, or at least one end of the main beam 131 and the free ends of some of the support beams 132 both form mounting portions 134. The mounting portion 134 is located at the outer periphery of the spliced ​​assembly and is provided with a corresponding leveling device 6.

[0109] Specifically, the length direction of the main beam 131 is parallel to the length direction of the planar end. Both ends of the length direction of the main beam 131 are free ends and are located at the arc-shaped ends of the splicing module 1 to form the mounting part 134.

[0110] Among the two support beams 132 located on the side of the main beam 131 away from the plane, the free end of the support beam 132 is located at the arc end of the splicing module 1 to form the mounting part 134.

[0111] Therefore, each splicing module 1 has four mounting parts 134 at the bottom of its arc-shaped end. The four mounting parts 134 are arranged at intervals along the circumference of the splicing module 1, so that the concrete platform body has eight mounting parts 134 arranged at intervals along the circumference of the concrete platform body, and all eight mounting parts 134 are located at the bottom of the outer periphery of the concrete platform body.

[0112] Each installation section 134 is equipped with a corresponding leveling device 6, so that the outer periphery of the concrete platform body is provided with eight leveling devices 6 arranged at intervals along the circumference.

[0113] Since the main beam 131 and the support beam 132 support the spliced ​​plate 12, and the leveling device 6 also provides support during leveling, the leveling device 6 is installed on the mounting part 134 formed by the main beam 131 and the support beam 132. This is to transfer the supporting force of the leveling device 6 to the main beam 131 and the support beam 132, thus avoiding stress concentration and deformation damage to the spliced ​​plate 12 if the leveling device 6 is installed on the spliced ​​plate 12.

[0114] Meanwhile, since the main beam 131 and the support beam 132 are located at the bottom of the splicing plate 12, placing the leveling device 6 on the mounting part 134 formed by the main beam 131 and the support beam 132 can also avoid the interference problem caused by the main beam 131 and the support beam 132 being lower than the leveling device 6 when the leveling device 6 is placed on the splicing plate 12.

[0115] It is understood that the installation part is not limited to being formed on both the main beam and the support beam. In some other embodiments, the tower operating platform includes multiple fan-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform. The splicing support beam of the splicing module is fishbone shaped. The main beam extends radially along the tower operating platform, and one end of the main beam is located at the arc end of the splicing module to form the installation part. Multiple support beams are provided on both sides of the width of the main beam. Multiple support beams on the same side are arranged at intervals along the length of the main beam. The support beams are arranged at an acute angle to the main beam. In two splicing modules that are adjacent in the circumference, multiple support beams on one side of the main beam of one splicing module are relatively close to and correspond one-to-one with multiple support beams on the other side of the main beam of the other splicing module, and are connected by post-casting strips. Therefore, only the main beam forms the installation part.

[0116] As shown in Figures 4-6, the leveling device 6 includes a guide sleeve assembly 61 and an adjusting member 62. The guide sleeve assembly 61 is cylindrical in the vertical direction. The guide sleeve assembly 61 is cast vertically within the mounting portion 134, or the guide sleeve assembly 61 is cast vertically within the mounting portion 134 and the splicing plate 12. Optionally, the guide sleeve assembly 61 is cast vertically within the mounting portion 134.

[0117] The adjusting member 62 extends vertically, and at least a portion of the adjusting member 62 passes through the guide sleeve assembly 61. The adjusting member 62 is movable vertically relative to the guide sleeve assembly 61 and can extend from the bottom of the mounting part 134. Thus, by adjusting the vertical position of multiple adjusting members 62, the stability of the tower operating platform 10 is adjusted. The guide sleeve assembly 61 guides and installs the adjusting members 62 and prevents damage to the concrete of the splicing module 1 when the adjusting members 62 move.

[0118] It should be noted that the leveling device 6, or the mounting part 134 equipped with the leveling device 6, is mounted on the supporting component. It can be optionally mounted on the bearing seat 30 inside the tower body 20. By adjusting the extension length of the adjusting member 62 from the bottom of the mounting part 134, the vertical position of the corresponding position of the splicing plate 12 is adjusted. Thus, by adjusting the vertical position of multiple adjusting members 62, the stability of the tower operating platform 10 is adjusted. Since the stability of the tower operating platform 10 is adjusted by the cooperation of multiple leveling devices 6, during the leveling process, the leveling device 6 is not limited to extending from the bottom of the mounting part 134. In other words, the bottom of the leveling device 6 can be located inside the mounting part 134, in which case the mounting part 134 equipped with the leveling device 6 serves a supporting function.

[0119] Specifically, when the tower operating platform 10 is in a stable state, the bottom of all the adjusting parts 62 can be located in the corresponding mounting parts 134. At this time, the mounting parts 134 equipped with the leveling device 6 ensure the stability of the tower operating platform 10. Alternatively, several adjusting parts 62 can extend out. The stability of the tower operating platform 10 is ensured by the cooperation of several extended adjusting parts 62 or by several extended adjusting parts 62 and several mounting parts 134 where the adjusting parts 62 do not extend out.

[0120] As shown in Figures 4 and 6, the guide sleeve assembly 61 includes a sleeve 611 and a nut 612. The sleeve 611 is cylindrical in the vertical direction and the inner circumferential surface of the sleeve 611 is smooth. The nut 612 is located at the bottom of the sleeve 611 and is coaxially arranged with the sleeve 611. Optionally, the bottom surface of the nut 612 is flush with the bottom surface of the mounting part 134.

[0121] The adjusting element 62 can be a bolt, which passes sequentially through the sleeve 611 and the nut 612 and is threadedly connected to the nut 612. The length of the bolt extending from the bottom of the nut 612 can be adjusted by rotating the bolt, thereby adjusting the length of the bolt extending from the bottom of the mounting part 134. The sleeve 611 serves to guide and install the bolt, and can prevent damage to the concrete of the splicing module 1 when the bolt moves.

[0122] Furthermore, the guide sleeve assembly 61 also includes an anchor plate 613, which is horizontally positioned and connected to the bottom of the sleeve 611. A nut 612 is located at the bottom of the anchor plate 613. The anchor plate 613 has a through hole extending vertically through the anchor plate 613, which communicates with both the sleeve 611 and the nut 612 for inserting a bolt serving as an adjusting member 62. The sleeve 611, nut 612, and anchor plate 613 are all cast within the splicing module 1, and the anchor plate 613 serves to enhance the stability of the guide sleeve assembly 61.

[0123] Furthermore, the top surface of the splicing plate 12 is provided with a countersunk hole 14, which is connected to the top of the sleeve 611. The head of the bolt, which serves as the adjusting element 62, is located in the countersunk hole 14, so that the bolt, which serves as the adjusting element 62, can be rotated by a tool. At the same time, it avoids the head of the bolt, which serves as the adjusting element 62, from being higher than the top surface of the splicing plate 12, thus avoiding any safety hazards to the operators.

[0124] As shown in Figures 1-7, the wind turbine tower provided in this embodiment includes a tower body 20, a support base 30, and a tower operating platform 10. The support base 30 is located on the inner circumferential surface of the tower body 20, and there are multiple support bases 30 arranged at intervals along the circumference of the tower body 20. The tower operating platform 10 is the tower operating platform 10 provided in this embodiment, located inside the tower body 20 and mounted on the multiple support bases 30.

[0125] As shown in Figures 4 and 7, the tower body 20 is a cylindrical shape in the vertical direction. The inner circumferential surface of the tower body 20 is provided with multiple bearing seats 30 arranged at intervals along the circumference of the tower body 20. The tower operating platform 10 is located inside the tower body 20 and is provided on the multiple bearing seats 30 for operators to install and maintain equipment.

[0126] The wind turbine tower provided in this application embodiment has a tower operation platform, which ensures the installation time and cycle of the wind turbine tower and has a lower production cost. The tower operation platform is set on multiple bearing seats on the inner circumferential surface of the tower body to ensure the stability of the tower operation platform installation and facilitate the installation of the tower operation platform.

[0127] Furthermore, multiple leveling devices 6 of the tower operating platform 10 are correspondingly mounted on multiple support seats 30. The stability of the tower operating platform 10 can be ensured by adjusting the multiple leveling devices 6.

[0128] Specifically, as shown in Figures 4 and 5, there are multiple support seats 30 that correspond one-to-one with the mounting parts 134, and there can be eight of them. The eight mounting parts 134 and the leveling devices 6 are installed on the eight support seats 30 in a one-to-one manner to ensure the stability of the tower operating platform 10.

[0129] The support base 30 includes a bracket 301 and limiting plates 302. The bracket 301 is disposed on the inner circumferential surface of the tower body 20. At least two limiting plates 302 are provided on the top of the bracket 301, optionally two limiting plates 302. The two limiting plates 302 are arranged at intervals along the circumference of the tower body 20. The corresponding mounting part 134 and the provided leveling device 6 are located between the two limiting plates 302, so as to limit the position of the mounting part 134 and the provided leveling device 6 by the two limiting plates 302, and prevent the mounting part 134 and the provided leveling device 6 from detaching from the support base 30.

[0130] Furthermore, the tower body 20 is made of cast concrete. The support base 30 also includes connecting components 303, which can be selected as four. The connecting components 303 extend radially along the tower body 20. One end of the connecting component 303 is located inside the wall of the tower body 20, and the other end of the connecting component 303 is connected to the bracket 301, so as to fix the bracket 301 to the inner circumferential surface of the tower body 20 through the connecting components 303.

[0131] The connecting component 303 may include a sleeve and a bolt, both of which extend radially along the tower body 20. The sleeve is fitted around the outer periphery of the bolt thread, and the head of the bolt is located outside the sleeve. The ends of both the sleeve and the bolt with heads are cast into the wall of the tower body 20. The tail of the bolt is also located outside the sleeve and extends out from the inner circumferential surface of the tower body 20. The tail of the bolt can be threaded to the bracket 301, or the tail of the bolt can be threaded onto the bracket 301 and threaded to a nut to fix the bracket 301. Optionally, the bracket 301 can be fixed by using a nut.

[0132] It is understood that the connecting components are not limited to sleeves and bolts. In other embodiments, the connecting components include anchor bolts, one end of which is anchored to the wall of the tower body, and the other end of which is connected to the bracket.

[0133] As shown in Figures 1, 2 and 7, the wind turbine tower provided in this application embodiment also includes an extension plate 40. The extension plate 40 is disposed at the outer periphery of the tower operating platform 10 and extends along the circumference of the tower operating platform 10. At least a portion of the extension plate 40 is located between the tower operating platform 10 and the tower body 20.

[0134] Specifically, the extension plate 40 is a ring-shaped structure in the vertical direction and surrounds the outer periphery of the tower operating platform 10. The inner periphery of the extension plate 40 is connected to the outer periphery of the tower operating platform 10, and the outer periphery of the extension plate 40 abuts against the inner periphery of the tower body 20. Thus, the extension plate 40 blocks the gap between the outer periphery of the tower operating platform 10 and the inner periphery of the tower body 20, thereby avoiding potential safety hazards.

[0135] The extension plate 40 can be a single piece or it can include multiple arc-shaped plates arranged sequentially along the circumference of the tower operating platform 10.

[0136] Optionally, the extension plate 40 is made of steel, and its inner peripheral end rests on the top surface of the arc-shaped end of the splicing plate 12, and is connected by connectors such as bolts. It is understood that in some other embodiments, a step may be provided on the arc surface of the arc-shaped end of the splicing plate 12, and the inner peripheral end of the extension plate 40 may be placed on the step.

[0137] Optionally, the outer peripheral end of the extension plate 40 is provided with an elastic layer, such as a rubber layer.

[0138] The manufacturing process of the wind turbine tower provided in this application embodiment includes manufacturing a tower operating platform 10. The tower operating platform 10 is then hoisted into the tower body 20. The tower operating platform 10 is leveled. An extension plate 40 is then installed.

[0139] The specific steps of manufacturing the tower operating platform 10 include pouring concrete to create the splicing modules 1. Concrete is poured between two adjacent splicing modules 1 to form a post-pouring strip 2, allowing at least two splicing modules 1 to be connected and forming the main body of the concrete platform. Accessories are installed on the main body of the concrete platform, including at least one of a railing 3, a perforated plate 7, a mounting frame, and a mounting railing.

[0140] Optionally, the splicing module 1 is prefabricated in the factory, and then the post-cast strip 2 is poured on the hoisting site.

[0141] It should be noted that during the casting and manufacturing of the splicing module 1, the leveling device 6 has been cast into the corresponding splicing module 1.

[0142] The tower operation platform 10 and the wind turbine tower provided according to embodiments of this application are described below with reference to Figures 1-7.

[0143] The inventors also discovered that in related technologies, steel is used for the operating platform to ensure its stability. However, steel operating platforms have many parts, making them prone to loss during transportation and storage. Furthermore, the production cost of steel operating platforms is high. To avoid these technical problems with steel operating platforms and to ensure their stability, the inventors proposed the tower operating platform 10 and wind turbine tower provided in the embodiments of this application.

[0144] As shown in Figures 1-7, the tower operation platform 10 provided in this embodiment includes a concrete platform body and a leveling device 6.

[0145] The leveling device 6 is located at the outer periphery of the concrete platform body. There are multiple leveling devices 6, which are arranged at intervals along the circumference of the concrete platform body.

[0146] As shown in Figures 1-7, the tower operating platform 10 is horizontally installed inside the tower body 20 and is used by operators to install and maintain the equipment.

[0147] The main body of the concrete platform is made of concrete and is horizontally set, and can be circular. At least three leveling devices 6 are provided on the outer periphery of the main body of the concrete platform, and the at least three leveling devices 6 are arranged at intervals along the circumference of the main body of the concrete platform.

[0148] The leveling device 6 is used to level the concrete platform body to prevent the tower operating platform 10 from swaying vertically within the tower body 20.

[0149] To ensure the stability of the tower operating platform 10 and prevent it from swaying due to factors such as operator movement, the leveling device 6 is configured with at least three units to form a stable support.

[0150] The tower operating platform provided in this application embodiment is equipped with multiple leveling devices on the concrete platform body to ensure the stability of the concrete platform body, thereby giving the tower operating platform a high degree of stability. At the same time, the concrete platform body makes the tower operating platform have a lower production cost, a simpler structure, and prevents parts from being lost during transportation and stacking.

[0151] As shown in Figures 1-3, the main body of the concrete platform includes a flat plate and a support beam. The flat plate is horizontally arranged and can be circular. The support beam is located at the bottom of the flat plate to support it. The support beam is grid-shaped and has multiple mounting parts 134. The mounting parts 134 are located at the outer periphery of the flat plate. The multiple mounting parts 134 are arranged at intervals along the circumference of the flat plate. At least some of the mounting parts 134 are provided with corresponding leveling devices 6. Optionally, each mounting part 134 is provided with a corresponding leveling device 6.

[0152] Since the support beam supports the plate, and the leveling device 6 also supports the plate during leveling, the leveling device 6 is installed on the mounting part 134 formed by the support beam. This is to transfer the supporting force of the leveling device 6 to the support beam, thus avoiding stress concentration and deformation damage to the plate if the leveling device 6 is installed on the plate.

[0153] Meanwhile, since the support beam is located at the bottom of the plate, placing the leveling device 6 on the mounting part 134 formed by the support beam can also avoid interference problems caused by the support beam being lower than the leveling device 6 when the leveling device 6 is placed on the plate.

[0154] It is understood that the leveling device is not limited to the mounting part formed by the support beam. In other embodiments, the concrete platform body includes a flat plate, and the leveling device is located on the flat plate.

[0155] Both the flat plate and the supporting beam are made of concrete and are connected as a single piece.

[0156] The support beams provide support to the slab, ensuring its strength while reducing the thickness and weight of the concrete platform and the amount of concrete used.

[0157] The flat plate and the support beam can be integral or spliced ​​together. Optionally, the flat plate includes at least two spliced ​​flat plates 12, and the support beam includes at least two spliced ​​support beams 13. The at least two spliced ​​support beams 13 are correspondingly located at the bottom of the at least two spliced ​​flat plates 12, so that the corresponding flat plate 12 and spliced ​​support beam 13 form a splicing module 1. In other words, the main body of the concrete platform includes at least two spliced ​​modules 1, and each splicing module 1 includes a corresponding spliced ​​flat plate 12 and spliced ​​support beam 13. The spliced ​​flat plate 12 and spliced ​​support beam 13 of each splicing module 1 are integrally connected.

[0158] The plate and support beam are configured as at least two spliced ​​plate 12 and at least two spliced ​​support beam 13, forming at least two spliced ​​modules 1 that are spliced ​​together, which facilitates the production and processing of the concrete platform body.

[0159] As shown in Figures 1-3, the main body of the concrete platform also includes a post-pouring strip 2, which is poured and connected between two adjacent splicing modules 1.

[0160] The tower operating platform 10 may optionally include two semi-circular splicing modules 1, each splicing module 1 having an arc-shaped end and a flat end in the horizontal direction, with the flat ends of the two splicing modules 1 facing each other. A post-cast strip 2 is made of cast concrete and is cast and connected between the flat ends of the two splicing modules 1 to allow the two splicing modules 1 to be spliced ​​together. Specifically, the splicing plate 12 of the two splicing modules 1 is cast and connected by the post-cast strip 2, and the splicing support beam 13 of the two splicing modules 1 is also cast and connected by the post-cast strip 2.

[0161] It is understood that the tower operating platform is not limited to including two semi-circular splicing modules. In other embodiments, the tower operating platform includes multiple fan-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform.

[0162] It is understood that the splicing modules are not limited to including arc-shaped ends and planar ends. In other embodiments, the tower operating platform includes multiple triangular splicing modules, which are sequentially connected along the circumference of the tower operating platform to form a polygonal concrete platform body. In other words, the triangular splicing module has three planar ends, two of which are arranged along the circumference of the tower operating platform and are used to connect other splicing modules on the corresponding side, and the remaining planar end is connected between the two planar ends to form the outer circumferential surface of the polygonal concrete platform body.

[0163] As shown in Figures 1-3, the end face of the splicing module 1 used to connect the post-pouring strip 2 has multiple protruding connecting ribs 11. In two adjacent splicing modules 1, the multiple connecting ribs 11 of one splicing module 1 are lapped and connected to the multiple connecting ribs 11 of the other splicing module 1 in a one-to-one correspondence, and are poured into the post-pouring strip 2. The two lapped connecting ribs 11 can be further connected by binding wire.

[0164] Specifically, both the splicing plate 12 and the splicing support beam 13 have steel mesh, and the steel mesh has multiple connecting bars 11. The portion of the splicing plate 12 located at the planar end has a portion of the connecting bars 11 extending outwards, and the portion of the splicing support beam 13 located at the planar end has another portion of the connecting bars 11 extending outwards. In two adjacent splicing modules 1, the connecting bars 11 of the splicing plate 12 of one splicing module 1 are connected one-to-one with the connecting bars 11 of the splicing plate 12 of the other splicing module 1, and the connecting bars 11 of the splicing support beam 13 of one splicing module 1 are connected one-to-one with the connecting bars 11 of the splicing support beam 13 of the other splicing module 1.

[0165] The post-cast strip 2 connects the splicing plates 12 of two adjacent splicing modules 1 and the splicing support beams 13 of two adjacent splicing modules 1. Specifically, the post-cast strip 2 includes an integrally connected strip portion and a protrusion portion. The strip portion extends horizontally and is cast between the two splicing plates 12. The connecting ribs 11 extending from the two splicing plates 12 are located inside the strip portion. The bottom of the strip portion has a protrusion portion, which is cast between the two splicing support beams 13. The connecting ribs 11 extending from the two splicing support beams 13 are located inside the protrusion portion.

[0166] The post-cast strip 2 connects the adjacent splicing plate 12 and the adjacent splicing support beam 13 to ensure the connection stability between the splicing modules 1 and the strength of the tower operating platform 10.

[0167] As shown in Figures 1-3, the splicing support beam 13 includes a main beam 131 and a support beam 132. At least one end of the support beam 132 is connected to the main beam 131, and the support beam 132 is set at an angle to the main beam 131. Several main beams 131 and at least two support beams 132 are staggered and connected. At least some of the support beams 132 have free ends forming connection parts 133. In two adjacent splicing modules 1, the connection parts 133 of one splicing module 1 are set one-to-one with the connection parts 133 of the other splicing module 1, and are connected by casting through the post-pouring strip 2.

[0168] Specifically, the length direction of the main beam 131 is orthogonal to the length direction of the support beam 132. The length direction of the main beam 131 is parallel to the length direction of the planar end. At least two support beams 132 are provided on both sides of the width direction of the main beam 131. The at least two support beams 132 on the same side are arranged at intervals along the length direction of the main beam 131. Optionally, three support beams 132 are provided on the side of the main beam 131 facing the planar end, and two support beams 132 are provided on the side of the main beam 131 away from the planar end. Along the length direction of the main beam 131, the support beams 132 on the side away from the planar end are located between two adjacent support beams 132 facing the planar end.

[0169] The support beam 132 has a connecting end and a free end that are arranged opposite to each other along the length direction. The connecting end is connected to the main beam 131. Among the three support beams 132 located on the side of the main beam 131 facing the plane end, the free end of the support beam 132 is located at the plane end of the splicing module 1 to form a connecting part 133. Therefore, the plane end of the splicing module 1 has three connecting parts 133 arranged at intervals. The connecting part 133 has multiple protruding connecting ribs 11. The three connecting parts 133 of one splicing module 1 are arranged one-to-one with the three connecting parts 133 of another splicing module 1 and are connected by casting through the post-pouring strip 2.

[0170] It is understood that the arrangement of the main beam and the support beam is not limited to that shown in Figure 3. In other embodiments, the tower operating platform includes multiple fan-shaped splicing modules. The multiple fan-shaped splicing modules are connected sequentially along the circumference of the tower operating platform. The splicing support beam of the splicing module is fishbone shaped. The main beam extends radially along the tower operating platform. Multiple support beams are provided on both sides of the width of the main beam. Multiple support beams on the same side are arranged at intervals along the length of the main beam. The support beams are arranged at an acute angle to the main beam. In two splicing modules that are adjacent in the circumference, multiple support beams on one side of the main beam of one splicing module are relatively close to and corresponding to multiple support beams on the other side of the main beam of the other splicing module, and are connected by post-casting strips.

[0171] As shown in Figures 1-5, at least one end of the main beam 131 forms a mounting portion 134, or at least one end of the main beam 131 and the free ends of some of the support beams 132 both form mounting portions 134.

[0172] Specifically, the length direction of the main beam 131 is parallel to the length direction of the planar end. Both ends of the length direction of the main beam 131 are free ends and are located at the arc-shaped ends of the splicing module 1 to form the mounting part 134.

[0173] Among the two support beams 132 located on the side of the main beam 131 away from the plane, the free end of the support beam 132 is located at the arc end of the splicing module 1 to form the mounting part 134.

[0174] Therefore, each splicing module 1 has four mounting parts 134 at the bottom of its arc-shaped end. The four mounting parts 134 are arranged at intervals along the circumference of the splicing module 1, so that the tower operating platform 10 has eight mounting parts 134 arranged at intervals along the circumference of the concrete platform body, and all eight mounting parts 134 are located at the bottom of the outer periphery of the concrete platform body.

[0175] Each installation section 134 is equipped with a corresponding leveling device 6, so that the outer periphery of the concrete platform body is provided with eight leveling devices 6 arranged at intervals along the circumference.

[0176] It is understood that the installation part is not limited to being formed on both the main beam and the support beam. In some other embodiments, the tower operating platform includes multiple fan-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform. The splicing support beam of the splicing module is fishbone shaped. The main beam extends radially along the tower operating platform, and one end of the main beam is located at the arc end of the splicing module to form the installation part. Multiple support beams are provided on both sides of the width of the main beam. Multiple support beams on the same side are arranged at intervals along the length of the main beam. The support beams are arranged at an acute angle to the main beam. In two splicing modules that are adjacent in the circumference, multiple support beams on one side of the main beam of one splicing module are relatively close to and correspond one-to-one with multiple support beams on the other side of the main beam of the other splicing module, and are connected by post-casting strips. Therefore, only the main beam forms the installation part.

[0177] It is understood that, not limited to each splicing module being equipped with a leveling device, in some other embodiments, the tower operating platform includes three or more sector-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform. In this case, some splicing modules are not equipped with leveling devices.

[0178] As shown in Figures 1-5, the leveling device 6 is cast inside the mounting portion 134, or the leveling device 6 is cast inside the mounting portion 134 and the plate. The leveling device 6 can extend from the bottom of the mounting portion 134.

[0179] The casting and fixing of the leveling device 6 facilitates its installation and fixation, and also prevents it from being lost during the transportation and stacking of the tower operating platform 10.

[0180] It is understood that the leveling device is not limited to being cast inside the concrete platform body; in other embodiments, the leveling device is located on the outer circumferential surface of the concrete platform body.

[0181] As shown in Figures 4-6, the leveling device 6 includes a guide sleeve assembly 61 and an adjusting member 62. The guide sleeve assembly 61 is cylindrical in the vertical direction. The guide sleeve assembly 61 is cast vertically within the mounting portion 134, or the guide sleeve assembly 61 is cast vertically within the mounting portion 134 and the splicing plate 12. Optionally, the guide sleeve assembly 61 is cast vertically within the mounting portion 134.

[0182] The adjusting member 62 extends vertically, and at least a portion of the adjusting member 62 passes through the guide sleeve assembly 61. The adjusting member 62 is movable vertically relative to the guide sleeve assembly 61 and can extend from the bottom of the mounting portion 134. Thus, by adjusting the vertical position of multiple adjusting members 62, the stability of the tower operating platform 10 is adjusted. The guide sleeve assembly 61 guides and installs the adjusting members 62 and prevents damage to the concrete of the concrete platform body when the adjusting members 62 move.

[0183] It should be noted that the leveling device 6, or the mounting part 134 equipped with the leveling device 6, is mounted on the supporting component. It can be optionally mounted on the bearing seat 30 inside the tower body 20. By adjusting the extension length of the adjusting member 62 from the bottom of the mounting part 134, the vertical position of the corresponding position of the splicing plate 12 is adjusted. Thus, by adjusting the vertical position of multiple adjusting members 62, the stability of the tower operating platform 10 is adjusted. Since the stability of the tower operating platform 10 is adjusted by the cooperation of multiple leveling devices 6, during the leveling process, the leveling device 6 is not limited to extending from the bottom of the mounting part 134. In other words, the bottom of the leveling device 6 can be located inside the mounting part 134, in which case the mounting part 134 equipped with the leveling device 6 serves a supporting function.

[0184] Specifically, when the tower operating platform 10 is in a stable state, the bottom of all the adjusting parts 62 can be located in the corresponding mounting parts 134. At this time, the mounting parts 134 equipped with the leveling device 6 ensure the stability of the tower operating platform 10. Alternatively, several adjusting parts 62 can extend out. The stability of the tower operating platform 10 is ensured by the cooperation of several extended adjusting parts 62 or by several extended adjusting parts 62 and several mounting parts 134 where the adjusting parts 62 do not extend out.

[0185] As shown in Figures 4 and 6, the guide sleeve assembly 61 includes a sleeve 611 and a nut 612. The sleeve 611 is cylindrical in the vertical direction and the inner circumferential surface of the sleeve 611 is smooth. The nut 612 is located at the bottom of the sleeve 611 and is coaxially arranged with the sleeve 611. Optionally, the bottom surface of the nut 612 is flush with the bottom surface of the mounting part 134.

[0186] The adjusting element 62 can be a bolt, which passes sequentially through the sleeve 611 and the nut 612 and is threadedly connected to the nut 612. The length of the bolt extending from the bottom of the nut 612 can be adjusted by rotating the bolt, thereby adjusting the length of the bolt extending from the bottom of the mounting part 134. The sleeve 611 guides and installs the bolt, and prevents damage to the concrete of the concrete platform body when the bolt moves.

[0187] Furthermore, the guide sleeve assembly 61 also includes an anchor plate 613, which is horizontally positioned and connected to the bottom of the sleeve 611. A nut 612 is located at the bottom of the anchor plate 613. The anchor plate 613 has a through hole extending vertically through the anchor plate 613, which communicates with both the sleeve 611 and the nut 612 for inserting a bolt serving as an adjusting member 62. The sleeve 611, nut 612, and anchor plate 613 are all cast within the concrete platform body, and the anchor plate 613 serves to enhance the stability of the guide sleeve assembly 61.

[0188] Furthermore, the top surface of the plate is provided with a countersunk hole 14, which is connected to the top of the sleeve 611. The head of the bolt, which serves as the adjusting element 62, is located inside the countersunk hole 14, so that the bolt, which serves as the adjusting element 62, can be rotated by a tool. At the same time, it avoids the head of the bolt, which serves as the adjusting element 62, from being higher than the top surface of the spliced ​​plate 12, thus avoiding safety hazards to the operators.

[0189] As shown in Figures 1-3, the tower operating platform 10 also includes a fence, which is set on a flat plate. The flat plate has elevator holes and cable holes arranged at intervals. The elevator holes and cable holes are offset from the support beams, and the fence surrounds the elevator holes.

[0190] Specifically, the elevator hole 4 penetrates the splicing plate 12 of the two splicing modules 1 in a vertical direction. The elevator hole 4 includes two connected sub-holes. The two sub-holes are respectively set on the splicing plate 12 of the two splicing modules 1 and located at the planar end of the splicing module 1. The post-pouring strip 2 is divided into two intervals by the elevator hole 4.

[0191] The cable hole 5 is located on the splicing plate 12 of one of the splicing modules 1 and passes through the splicing plate 12 in a vertical direction.

[0192] Both elevator hole 4 and cable hole 5 are offset from main beam 131 and support beam 132.

[0193] The fence 3 is set on a flat plate, specifically on the splicing flat plate 12 of the two splicing modules 1, and the fence 3 is set around the elevator hole 4 in a vertical direction.

[0194] The elevator opening 4 and the fence 3 allow the elevator and elevator track to pass vertically. The fence 3 also separates the space it surrounds from the work area on the flatbed, protecting the operators on the flatbed from accidental collisions with the operating elevator or accidental falls through the elevator opening 4. Optionally, the fence 3 is equipped with an openable and closable gate for operator passage.

[0195] Cable hole 5 is used for cables to pass through in a vertical direction. Optionally, the tower operating platform 10 also includes an orifice plate 7, which covers the cable hole 5 and has through holes for cables to pass through. This prevents operators on the platform from accidentally falling through the cable hole 5. During operation, the orifice plate 7 is prohibited from being stepped on and is marked with signs to avoid safety hazards.

[0196] Both the fence 3 and the perforated plate 7 can be made of steel and are mounted on the flat plate by means of connectors such as bolts.

[0197] It should be noted that the elevator hole is not limited to being located on two splicing plates simultaneously. In other embodiments, the elevator hole can be located on the splicing plate of one splicing module or on the splicing plate of multiple splicing modules. For example, the tower operating platform 10 includes multiple fan-shaped splicing modules, which are connected sequentially along the circumference of the tower operating platform 10. The elevator hole is located at the splicing center of the multiple fan-shaped splicing modules. In other words, the elevator hole is located at the center of the concrete platform body.

[0198] It should be noted that the cable holes are not limited to being located on the splicing plate of one splicing module. In other embodiments, the cable holes are also located on the splicing plates of two splicing modules. The cable holes and elevator holes are arranged at intervals along the length of the post-cast strip, and the post-cast strip is divided into three segments.

[0199] Furthermore, the splicing module 1 is also equipped with a mounting bracket or mounting rail for mounting and accommodating tools and equipment, such as fire extinguishers. Both the mounting bracket and mounting rail can be made of steel and are mounted on the flat plate using connectors such as bolts.
