TECHNICAL FIELD

[0001] The utility model relates to wind power tower drum bus connection technical field, specifically for a kind of soft support for wind power tower drum bus. BACKGROUND

[0002] In the field of wind power, the support of wind power tower drum bus is crucial to ensure the stable operation of wind power equipment. As a key component for wind power tower drum bus, the soft support plays a supporting and buffering role.

[0003] At present, the existing soft support mostly adopts single-piece structure. In actual application process, when the strength of such single-piece structure soft support cannot meet the working condition requirement, it is usually necessary to increase fixing plate to fix multiple soft supports, so that they can work together to meet the required strength requirement. Typical structure is the bus soft support structure disclosed in application number CN201610553964.8. However, this way of fixing multiple soft supports by increasing fixing plate has obvious disadvantages. On the one hand, during installation, multiple soft supports and fixing plate need to be accurately positioned and fixed, which is tedious and consumes a lot of time and labor cost. On the other hand, during disassembly and maintenance, it is also necessary to spend a lot of effort to release the connection between fixing plate and multiple soft supports, which makes disassembly and assembly very inconvenient, seriously affects the maintenance efficiency of wind power equipment and increases operation and maintenance cost.

[0004] Therefore, in order to overcome the problem of inconvenient disassembly and assembly of soft support in the prior art when the strength is insufficient, the present application proposes a new soft support structure for wind power tower drum bus. SUMMARY

[0005] The utility model provides a kind of soft support for wind power tower drum bus to the deficiency in the background art.

[0006] The technical scheme adopted by the utility model is: a kind of soft support for wind power tower drum bus, including semicircular arc section and fixed section integrally formed on both ends of semicircular arc section, further including elastic reinforcing ring, the fixed section has thickening portion that thickens inward, at least two insertion slots are provided on the thickening portion, and both ends of the elastic reinforcing ring are connected and inserted into the insertion slot.

[0007] Further, the elastic reinforcing ring is composed of a semicircular arc portion and a connecting portion integrally formed on both ends of the semicircular arc portion, and the connecting portion is inserted into the insertion slot.

[0008] Further, the elastic reinforcing ring is a metal elastic sheet.

[0009] Further, the fixed section and the connecting portion are provided with fixing holes.

[0010] Further, the four slots are provided.

[0011] Further, the thickened portion is provided with a clearance inclined surface on one side of the semicircular arc segment.

[0012] The utility model discloses the beneficial effect is:

[0013] 1. It is convenient to adjust intensity: the thickened portion on fixed section is provided with a plurality of slots for connecting elastic reinforcing ring. This design can flexibly increase or reduce the number of elastic reinforcing ring according to the different actual working conditions. When the working condition requires higher strength of the soft support, the overall strength can be effectively improved by increasing the elastic reinforcing ring. When the working condition requires relatively low, the elastic reinforcing ring can be reduced, and the flexible adjustment of the strength of the soft support is realized, so that different working environments can be better adapted.

[0014] 2. Convenient and efficient disassembly: the elastic reinforcing ring and the slot on the thickened portion adopt the plug-in cooperation mode. When installing, only the two ends of the elastic reinforcing ring are inserted into the corresponding slot, and the installation can be completed, which is simple and fast. When disassembling, the elastic reinforcing ring is directly pulled out of the slot, without complex tools and excessive operation steps.

[0015] 3. Compact and reasonable structure: the thickened portion on the fixed section not only provides space for the setting of the slot, but also enhances the strength and stability of the fixed section. The combination of the elastic reinforcing ring and the soft support body makes the whole soft support structure compact.

[0016] 4. Cost control advantage: since the soft support of the patent can flexibly adjust the number of elastic reinforcing rings according to actual needs, the use of complex multi-piece soft support and fixed plate structure when the strength requirement is not high is avoided, and the amount of material is reduced. At the same time, the convenient disassembly method also reduces the labor cost in the installation and maintenance process, effectively controls the cost from the aspects of material and labor, and improves the market competitiveness of the product.

[0017] 5. Wide application range: by flexibly adjusting the elastic reinforcing ring, the soft support can meet the strength requirements under different working conditions, which makes its application range more extensive. Whether in the area with rich wind resources and harsh working conditions, or in the environment with relatively stable wind resources, the performance of the soft support can be ensured by reasonably configuring the elastic reinforcing ring to provide reliable support for the wind power tower bus, thereby expanding the application scenarios of the product.

[0018] In addition to the purposes, features and advantages described above, the utility model has other purposes, features and advantages. The utility model will be further described in detail with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

[0025] The utility model provides a kind of soft support for wind power tower cylinder bus.

[0026] In the embodiment, with reference to Figs. 1-3 The soft support for wind power tower cylinder bus includes semicircular arc segment 1 and fixed segment 2 integrally formed on both ends of the semicircular arc segment, and also includes elastic reinforcing ring 3. The fixed segment 2 has thickened portion 4 that thickens inward. At least two insertion slots 5 are provided on the thickened portion 4, and both ends of the elastic reinforcing ring are connected and inserted into the insertion slots.

[0027] In the above technical solution, the soft support for wind power tower cylinder bus includes semicircular arc segment, fixed segment, elastic reinforcing ring and other structures. The fixed segment is integrally formed on both ends of the semicircular arc segment, which enhances the stability and reliability of the overall structure of the soft support and reduces the connection weakness problem caused by component splicing.

[0028] The thickened portion on the fixed segment thickens inward, which increases the strength and rigidity of the fixed segment, so that it can better withstand external force. At the same time, at least two insertion slots are provided on the thickened portion, which provides a connection basis for the installation of the elastic reinforcing ring.

[0029] The elastic reinforcing ring is arranged so that the strength of the soft support can be flexibly adjusted according to the actual working condition. When higher strength is required, the elastic reinforcing ring can be increased; when the working condition requires lower, the elastic reinforcing ring can be appropriately reduced or not used, improving the adaptability and versatility of the soft support. And the elastic reinforcing ring and the plug-in cooperation mode of the slot facilitate the installation and disassembly of the elastic reinforcing ring, reducing the maintenance cost and difficulty.

[0030] Specifically, the elastic reinforcing ring is composed of a semicircular arc part 6 and a connecting part 7 integrally formed at both ends of the semicircular arc part 6, and the connecting part 7 is inserted into the above-mentioned slot.

[0031] In this embodiment, the elastic reinforcing ring is composed of a semicircular arc part and a connecting part integrally formed at both ends of the semicircular arc part, and the connecting part is inserted into the slot. This structure design makes the shape of the elastic reinforcing ring match the semicircular arc segment of the soft support, which can better cooperate and provide support for the wind turbine tower busbar together.

[0032] In addition, the integrally formed connecting part and semicircular arc part ensure the strength and stability of the overall structure of the elastic reinforcing ring, avoiding the problem of elastic reinforcing ring failure due to weak connection parts.

[0033] Specifically, the elastic reinforcing ring is a metal elastic sheet.

[0034] In this embodiment, the elastic reinforcing ring is a metal elastic sheet, which has good elasticity and strength. When subjected to external force, the metal elastic sheet can be elastically deformed to a certain extent, absorbing and buffering the external force and protecting the wind turbine tower busbar from excessive impact force.

[0035] Specifically, the fixed segment and the connecting part are provided with a fixing hole 8.

[0036] In this embodiment, in order to improve the connection stability of the elastic reinforcing ring, a fixing hole corresponding to the fixed segment can be provided on the connecting part of the elastic reinforcing ring, so that the elastic reinforcing ring can be fixed by bolts after being inserted and connected. The fixing hole can also be fixedly connected with other accessories, such as Fig. 3 Thus, on the basis of plug-in, additional fixation is performed through the fixing hole, so that the elastic reinforcing ring is not easy to loosen or fall off even in long-term vibration and other harsh working conditions, ensuring the stability of the overall performance of the soft support.

[0037] Specifically, the slot is four.

[0038] In the embodiment, the slots are arranged in four, which can ensure the stability of the elastic reinforcing ring and provide more installation options. One, two, three or four elastic reinforcing rings can be selected according to the strength requirements of the actual working conditions, so that the strength adjustment of the soft support is more accurate and flexible.

[0039] Specifically, the thickened portion is provided with a clearance inclined surface 9 on one side of the semicircular arc segment.

[0040] In the embodiment, the thickened portion is provided with a clearance inclined surface on one side of the semicircular arc segment, and the design of the clearance inclined surface can facilitate the insertion of the two ends of the elastic reinforcing ring.

[0041] All technical personnel know: although the utility model has been described in the above specific implementation mode, the utility model idea is not limited to this utility model, and any modification using the utility model idea will be included in the patent protection range.
