[0034] In order to enable those skilled in the art to better understand the technical concept of the utility model, the specific embodiments of the utility model will be described clearly, completely and in detail in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. For those of ordinary skill in the art, the specific meanings of the terms used in the present invention can be understood according to the specific circumstances.

[0036] It will be understood that although terms such as "first", "second", etc. may be used herein to describe various elements, these elements will not be limited by these terms. Rather, these terms are only used to distinguish one element from another element. Therefore, without departing from the teachings of the exemplary embodiments described herein, the first element referred to in the exemplary embodiments may also be referred to as the second element.

[0037] For ease of description, the terms “inside”, “outside”, “upper” and “lower” referred to below are consistent with the inside, outside, upper and lower directions of the drawings themselves, but do not limit the structure of the present invention.

[0038] In addition, throughout the specification, when an element is described as being “disposed on,” “connected to,” or “coupled to” another element, the element may be directly “disposed on,” “connected to,” or “coupled to” the other element, or one or more other elements may be interposed therebetween.

[0039] The utility model aims to provide an inner tower platform for installation on a concrete section of a tower, and a tower and a wind turbine generator set comprising the inner tower platform. The inner tower platform has a smaller size and a smaller weight, thereby facilitating transportation, installation and adjustment, and can reduce manufacturing costs.

[0040] Figure 1 It is a horizontal cross-sectional view of the platform inside the tower according to the prior art. Figure 1As shown, the platform is a platform for elevators, including a platform panel 1, connectors 2 and a cover plate 3, wherein the remaining areas of the platform except for the areas where the steel strands and the ladder openings are located are covered by the platform panel 1, a plurality of connectors 2 are arranged on the periphery of the platform and are used to connect to supporting brackets arranged on the inner wall of the tower, and the cover plate 3 is used to cover the ladder opening.

[0041] However, if Figure 1 As shown, the entire platform is basically circular in shape with an inner diameter slightly smaller than that of the tower and has a plurality of connecting members 2 spaced apart from each other on the outer circumference. In this case, there are many connection points between the platform and the tower, resulting in complex installation and difficulty in adjustment. In addition, the platform is large in size, requiring high manufacturing costs and needs to be transported in petals, and is easily damaged during transportation and assembly.

[0042] The utility model aims to provide a tower inner platform which can overcome the above-mentioned disadvantages, and a tower and a wind turbine generator set comprising the tower inner platform.

[0043] In the following, reference will be made to Figure 2 and Figure 3 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An in-tower platform for mounting on a concrete segment of a tower according to a first embodiment is described in detail.

[0044] Figure 2 is a perspective view of a platform inside a tower according to the first embodiment, Figure 3 It is along Figure 2 A cross-sectional view taken along line AA in FIG.

[0045] like Figure 2 and Figure 3 As shown, in this embodiment, the platform in the tower may include a platform body 10, and the platform body 10 may include a platform frame 11 formed by a ring beam 110 and a platform panel 12 supported on the platform frame 11, wherein the platform panel 12 may have a through hole 13, and the ring beam 110 may include at least a first ring beam section 111 and a second ring beam section 112, wherein the first ring beam section 111 is used to connect with the tower wall of the concrete section, and the second ring beam section 112 has a predetermined distance from the tower wall facing it, so that a gap is formed between the platform body 10 and the tower wall, so as to form a passage between the platform body 10 and the tower wall. For the convenience of description, the platform in the tower is referred to as the platform below.

[0046] and Figure 1 Compared with the existing platform shown in the figure, in this embodiment, since a gap is formed between the platform body 10 and the tower wall to form a passage between the platform body 10 and the tower wall, the area of ​​the platform body 10 can be reduced, thereby reducing the weight of the platform.

[0047] In addition, if Figure 3As shown, the platform frame 11 may include a ring beam 110. Specifically, the platform frame 11 may be formed by enclosing the ring beam 110. Figure 1 Compared with the existing circular platform shown in the figure, in this embodiment, the platform frame 11 can be formed into a non-circular shape, so the amount of materials (such as steel, etc.) required for the platform can be reduced, and the platform does not need to be transported separately, which is convenient for transportation and helps to reduce costs. Figure 3 In addition to the semicircular shape shown, the platform frame 11 can also be formed into a fan-shaped ring shape, a trapezoidal shape, a rectangular shape, etc. In addition, the cross-section of the beam constituting the platform frame 11 can be an I-shaped, an angle steel type, a channel steel type, etc.

[0048] The ring beam 110 may include at least a first ring beam section 111 and a second ring beam section 112. In the present embodiment, the first ring beam section 111 may have an arc shape to facilitate connection with the tower wall, and the second ring beam section 112 may have a straight shape to facilitate forming a gap between the platform body 10 and the tower wall, but the shapes of the first ring beam section 111 and the second ring beam section 112 are not limited thereto. The number and shape of the constituent beams of the ring beam 110 may vary with the shape of the desired platform frame 11. In addition, in the present embodiment, the first ring beam section 111 may be composed of one sub-ring beam section, and the second ring beam section 112 may be composed of a first sub-ring beam section 112a, but not limited thereto, for example, each of the first ring beam section 111 and the second ring beam section 112 may be composed of multiple sub-ring beam sections.

[0049] The platform frame 11 may further include a reinforcing beam 113 to improve the reliability of the platform. The reinforcing beam 113 may be configured to span the ring beam 110. As an example, the reinforcing beam 113 may extend from the second ring beam section 112 to the first ring beam section 111 to reinforce the platform frame 11. However, the present invention is not limited thereto, and for example, the reinforcing beam 113 may be arranged according to the overall shape of the platform frame 11, the shape and number of the constituent beams of the platform frame 11, load requirements, etc.

[0050] The platform may further include a plurality of connectors 20. As an example, the plurality of connectors 20 may be arranged to be spaced apart from each other along the outer circumference of the ring beam 110 and used for connection with the supporting brackets of the tower wall of the concrete segment. As an example, the connector 20 may be arranged only on the first ring beam segment 111, but not on the second ring beam segment 112, but is not limited thereto, and the installation position of the connector 20 may be changed according to the structure and shape of the ring beam 110.

[0051] As described above, the weight of the platform according to the present embodiment can be reduced, so Figure 1Compared with the platform shown in FIG. 1 , the number of connecting members 20 required for the installation of the platform according to this embodiment can also be reduced. Thus, when the platform according to this embodiment is installed on the tower wall, only a relatively small number of connecting members 20 need to be used, thereby facilitating installation and adjustment and making the force transmission clear.

[0052] In this embodiment, the through opening 13 can be a ladder opening for the elevator. Although the area of ​​the platform body 10 according to this embodiment can be reduced, the platform according to this embodiment can meet the needs of maintenance personnel to enter and exit the elevator to complete the maintenance work of the components at the platform, and can provide sufficient rest space for maintenance personnel.

[0053] Although not in Figure 2 and Figure 3 However, the platform according to this embodiment may also include an inclined support assembly 30 (see Figure 4 ) to enhance the reliability of the platform support. That is, in this embodiment, the platform can be supported horizontally by the connecting member 20 and supported diagonally by the diagonal support assembly 30 to be more firmly installed in the tower. Figures 4 to 10 The installation and structure of the diagonal support assembly 30 are described in detail.

[0054] In addition, if Figure 3 As shown, the platform body 10 further includes a cover plate 14. The cover plate 14 may be connected to the platform frame 11 or the platform panel 12, and may be configured to openably and closably cover the through-opening 13 at least partially. By closing the cover plate 14 to at least partially cover the through-opening 13, maintenance personnel may be prevented from slipping from the through-opening 13, thereby improving the safety performance of the platform.

[0055] In addition, if Figure 2 As shown, the platform may also include a guardrail assembly 40, which is arranged on the ring beam 110 around the outer periphery of the platform panel 12 and extends in the vertical direction. Specifically, the guardrail assembly 40 may be fixedly arranged around the edge of the platform panel 12, and may extend a certain height in the vertical direction to prevent maintenance personnel from falling, thereby further improving the safety performance of the platform. In addition, an inner guardrail assembly may also be arranged at the edge of the through opening 13 to further improve the safety performance of the platform.

[0056] In the following, reference will be made to Figures 4 to 10 A platform for mounting on a concrete segment of a tower according to a second embodiment is described in detail.

[0057] Figure 4 is a perspective view of a platform in a tower according to a second embodiment, Figure 5 yes Figure 4 Right view of Figure 6 yes Figure 4 The left view of Figure 7yes Figure 4 A top-down perspective view of Figure 8 It is along Figure 4 The cross-sectional view taken along line BB in FIG. Fig. 9 is a plan view of a platform side connecting plate in a tower inner platform according to a second embodiment, Fig.10 4 is a plan view of a tower side connecting plate in a tower inner platform according to a second embodiment.

[0058] like Figures 4 to 7 As shown, in this embodiment, the platform may include a platform body 10. The platform body 10 may include a platform frame 11 and a platform panel 12 supported on the platform frame 11. The platform panel 12 may have a through opening 13. In this embodiment, the through opening 13 may be a ladder opening for a non-climbing device.

[0059] Specifically, Figure 7 and Figure 8 As shown, the platform frame 11 may be formed by enclosing a ring beam 110. In this embodiment, the platform frame 11 may be substantially formed in a trapezoidal shape, but is not limited thereto.

[0060] The ring beam 110 may include at least a first ring beam section 111 and a second ring beam section 112. In the present embodiment, the first ring beam section 111 may have an arc shape to facilitate connection with the tower wall, but the shape of the first ring beam section 111 is not limited thereto. In addition, the second ring beam section 112 may be composed of three sub-ring beam sections, that is, the first sub-ring beam section 112a, the second sub-ring beam section 112b and the third sub-ring beam section 112c are connected, but not limited thereto. For example, the second ring beam section 112 may be composed of more than three sub-ring beam sections, or may be composed of one or two sub-ring beam sections bent into a desired shape. As an example, the first sub-ring beam section 112a may be opposite to the first ring beam section 111 in the radial direction of the tower, and the second sub-ring beam section 112b and the third sub-ring beam section 112c may be respectively located at both ends of the first sub-ring beam section 112a to connect the first sub-ring beam section 112a to the first ring beam section 111.

[0061] In this embodiment, the first ring beam section 111 can be used to connect with the supporting bracket of the tower wall of the concrete section. Figure 4As shown, a plurality of connectors 20 may be arranged to be spaced apart from each other along the outer periphery of the first ring beam segment 111, and are used to connect the first ring beam segment 111 to the supporting corbels of the tower wall of the concrete segment. The second ring beam segment 112 has a predetermined distance from the tower wall it faces, so that a gap is formed between the platform body 10 and the tower wall to form a passage between the platform body 10 and the tower wall. Specifically, each of the first sub-ring beam segment 112a, the second sub-ring beam segment 112b, and the third sub-ring beam segment 112c has a predetermined distance from the tower wall it faces, so that a gap is formed between the platform body 10 and the tower wall to form a passage between the platform body 10 and the tower wall.

[0062] Compared with the first embodiment, in this embodiment, the size of the platform can be further reduced, and the weight of the platform can be further reduced, so that transportation can be further facilitated, costs can be reduced, and installation and adjustment can be facilitated.

[0063] In addition, similar to the first embodiment, in this embodiment, if Figure 7 and Figure 8 As shown, the platform frame 11 may also include a reinforcing beam 113 to improve the reliability of the platform. As an example, the reinforcing beam 113 spans the ring beam 110. Specifically, the reinforcing beam 113 may extend from the second sub-ring beam section 112b to the first ring beam section 111 to reinforce the platform frame 11.

[0064] like Figures 4 to 6 As shown, in this embodiment, the platform may further include an oblique support assembly 30 to enhance the reliability of the platform support. That is, in this embodiment, the platform may be supported horizontally by the connecting member 20 while being supported obliquely by the oblique support assembly 30 to be more firmly installed in the tower.

[0065] Specifically, the inclined support assembly 30 can be connected between the bottom of the platform frame 11 and the tower wall in an inclined manner to support the platform body 10. Figure 5 and Figure 6 As shown, as an example, there are two oblique support assemblies 30, and one of the two oblique support assemblies 30 can be connected between the bottom of the first sub-circle beam section 112a and the tower wall, and the other of the two oblique support assemblies 30 can be connected between the bottom of the reinforcing beam 113 and the tower wall. Optionally, both oblique support assemblies 30 can be connected between the bottom of the first sub-circle beam section 112a and the tower wall. Optionally, both oblique support assemblies 30 can be connected between the bottom of the reinforcing beam 113 and the tower wall. In addition, there is no special restriction on the number of oblique support assemblies 30, and any number of oblique support assemblies 30 can be set as needed. In addition, the arrangement position of the oblique support assembly 30 can be adjusted according to load requirements, space restrictions and other conditions.

[0066] like Figure 4As shown, the diagonal support assembly 30 may have a first end 30a for connecting to the bottom of the platform frame 11 and a second end 30b for connecting to the tower wall. Figure 5 As shown, the diagonal support assembly 30 may include a diagonal support beam 31 , a platform side connecting plate 32 and a tower side connecting plate 33 .

[0067] Specifically, Figure 6 As shown, the diagonal bracing beam 31 may extend obliquely from the first end 30a of the diagonal bracing assembly 30 toward the second end 30b of the diagonal bracing assembly 30. The platform side connecting plate 32 may be disposed at the first end 30a of the diagonal bracing assembly 30, and the tower side connecting plate 33 may be disposed at the second end 30b of the diagonal bracing assembly 30. Fig. 9 As shown, the platform side connecting plate 32 may have a platform side long strip hole 321 extending in the horizontal direction so as to be adjustably mounted on the bottom of the platform body 10 through a connecting member (such as a bolt, etc.). Fig.10 As shown, the tower side connecting plate 33 may have a tower side long strip hole 331 extending in the vertical direction so as to be adjustably mounted on the tower wall through a connecting member.

[0068] Optionally, the platform side connecting plate 32 may have a platform side long strip hole extending in the vertical direction so that it can be adjustably mounted on the bottom of the platform body 10 through a connecting member, and the tower side connecting plate 33 may have a tower side long strip hole extending in the horizontal direction so that it can be adjustably mounted on the tower wall through a connecting member.

[0069] Therefore, in this embodiment, when installing the diagonal support assembly 30, the platform side long strip hole 321 and the tower side long strip hole 331 can be used to adjust the horizontal direction and the vertical direction, thereby improving the installation efficiency. In addition, when the tower side long strip hole 331 is formed to extend in the vertical direction, it is more convenient to adjust the connection member passing through the tower side long strip hole 331 to align with the embedded part embedded in the concrete section of the tower.

[0070] In addition, as an example, the platform side connecting plate 32 and the tower side connecting plate 33 may be plates with a thickness of 10 mm to ensure reliable connection. The platform side elongated holes 321 and the tower side elongated holes 331 may be formed as elongated circular holes, rectangular elongated holes, etc.

[0071] The other components (such as the cover plate 14 and the guardrail assembly 40) included in the tower inner platform according to the first embodiment can also be applied to this embodiment, and the repeated description thereof is omitted here.

[0072] As described above, the tower inner platform according to the utility model can have a smaller size and a smaller weight, which can be convenient for transportation, installation and adjustment, and thus reduce the manufacturing cost. In addition, the tower inner platform according to the utility model can reduce the number of connection points with the tower wall, so as to facilitate installation and adjustment, and can perform oblique support while performing horizontal support, so as to improve the reliability of installation.

[0073] In addition, the utility model also provides a tower, which may include the tower inner platform as described above, thereby reducing the cost of the tower and facilitating the inspection and maintenance of the tower. In addition, the utility model also provides a wind turbine generator set, which may include the tower as described above, thereby ensuring the stable operation of the wind turbine generator set and improving the cost-effectiveness of the wind turbine generator set.

[0074] The above describes the specific implementation methods of the present invention in detail. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be combined, modified and improved without departing from the principle and spirit of the present invention whose scope is defined by the claims (for example, different technical features of the present invention can be combined to obtain new technical solutions). These combinations, modifications and improvements should also be within the scope of protection of the present invention.
