Description

Technical Field

[0001] This utility model relates to the field of cooling tower support equipment, specifically a fiberglass cooling tower support column with an irregular cross-section resistant to wind vibration. Background Technology

[0002] Traditional carbon steel cooling tower support beams commonly suffer from electrochemical corrosion in the high humidity and salt spray environment of cooling towers, requiring replacement on average every 3-5 years. Maintenance costs account for more than 30% of the total life-cycle cost of the cooling tower. Their significant weight necessitates the use of large hoisting equipment for installation, severely impacting construction efficiency. Currently, the market is searching for new materials that can effectively replace traditional carbon steel, with fiberglass being the preferred choice.

[0003] Fiberglass, scientifically known as fiber-reinforced plastic, commonly called FRP (Fiber Reinforced Plastics), is a type of fiber-reinforced composite plastic. It generally refers to reinforced plastics using glass fibers to strengthen unsaturated polyester, epoxy resin, and phenolic resin matrices, with glass fibers or their products as the reinforcing material. This is different from tempered glass. Due to the different types of resins used, there are polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. It is lightweight yet hard, non-conductive, has stable properties, high mechanical strength, low recyclability, and is corrosion-resistant. It can replace steel in the manufacture of machine parts and the outer shells of automobiles and ships.

[0004] While fiberglass possesses the aforementioned advantages, its bending stiffness is insufficient compared to traditional carbon steel. If fiberglass support columns are manufactured using traditional shapes, such as circular or square cross-sections, their adaptability to high wind conditions may be weakened. Specifically, traditional circular cross-section columns exhibit high wind resistance and are prone to vortex-induced vibration, while square cross-section columns show significant stress concentration at the corners. Both of these issues compromise the safety of the support columns for the cooling tower. Therefore, it is urgent to improve the traditional design of the support beams to mitigate the impact of high winds and ensure the safety of the fiberglass cooling tower support beams. Utility Model Content

[0005] The purpose of this invention is to provide a fiberglass cooling tower support column with an irregular cross-section that is resistant to wind vibration, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A fiberglass cooling tower support column with an irregular cross-section resistant to wind vibration includes a hollow cylindrical fiberglass column body, a support component inside the fiberglass column body, and connecting components fixed at both ends of the fiberglass column body; the cross-section of the fiberglass column body is a centrally symmetrical figure formed by several circular arcs connected end to end.

[0007] In a further embodiment, the centrally symmetrical shape is a clover shape formed by three identical circular arcs connected end to end.

[0008] In a further embodiment, the support assembly includes a main support rod fixed to the inner wall of the fiberglass column cavity by a plurality of sets of support sub-rods.

[0009] In a further embodiment, each set of support sub-rods is evenly arranged around the main support rod, and the density of the support sub-rods near both ends of the main support rod is greater than the density of the support sub-rods in the middle of the main support rod.

[0010] In a further embodiment, the connecting component is a flange that is simultaneously fixed to both the fiberglass column and the end of the supporting main rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: I. In this utility model, the cross-section of the fiberglass column is adjusted to a centrally symmetrical shape formed by several circular arcs connected end to end. The clover shape is preferred. This design is derived from the shape of a water droplet head with the lowest wind resistance coefficient. The support rod shape in this utility model can be obtained by arranging multiple water droplet head shapes centrally symmetrically. This shape can effectively disperse the impact force of airflow, thereby enhancing the adaptability of the fiberglass cooling tower support beam to strong wind environments.

[0012] Second, in this utility model, the support beam of the FRP cooling tower adopts a hollow structure, and the hollow structure is also equipped with support sub-rods and support main rods. This can maximize the lightweight advantage of FRP while further enhancing the bending resistance of the FRP cooling tower support beam. Moreover, the density of the support sub-rods at both ends of the support beam is greater than that in the middle of the support beam, which effectively ensures the connection strength at both ends of the support beam while reducing weight.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Implementation, for example Figure 1-3 As shown, this embodiment provides a fiberglass cooling tower support column with a wind-resistant irregular cross-section, including a hollow cylindrical fiberglass column 1. A support assembly is provided within the cavity of the fiberglass column 1, and connecting assemblies are fixed to both ends of the fiberglass column 1. The connecting assemblies are flanges 4 simultaneously fixed to the ends of the fiberglass column 1 and the main support rod 3. The cross-section of the fiberglass column 1 is a centrally symmetrical figure formed by several arcs connected end-to-end. The centrally symmetrical figure is a clover shape formed by three identical arcs connected end-to-end. In this embodiment, the cross-section of the fiberglass column is adjusted to a centrally symmetrical figure formed by several arcs connected end-to-end, preferably a clover shape. This design originates from the teardrop head shape, which has the lowest wind resistance coefficient. Arranging multiple teardrop head shapes centrally symmetrically yields the support rod shape of this invention. This shape effectively disperses the impact force of airflow, thereby enhancing the adaptability of the fiberglass cooling tower support beam to strong wind environments.

[0017] The support assembly includes a main support rod 3 fixed to the inner wall of the fiberglass column 1 by several sets of support sub-rods 2. Each set of support sub-rods 2 evenly surrounds the main support rod 3, and the density of the support sub-rods 2 near both ends of the main support rod 3 is greater than the density of the support sub-rods 2 in the middle of the main support rod 3. In this embodiment, the fiberglass cooling tower support beam adopts a hollow structure, and the hollow structure also contains support sub-rods 2 and main support rods 3. This can maximize the lightweight advantage of fiberglass while further enhancing the bending resistance of the fiberglass cooling tower support beam. Moreover, the density of the support sub-rods 2 at both ends of the support beam is greater than that in the middle of the support beam, effectively ensuring the connection strength at both ends of the support beam while reducing weight.

[0018] Furthermore, each set of supporting sub-rods 2 is centrally symmetrically arranged around the main supporting rod 3, and this center is the same as the rotation center of the cross-section of the fiberglass column 1; the main supporting rod 3 and the fiberglass column 1 share the same central axis; both ends of the main supporting rod 3 are also fixed to the flange 4, and the center point of the flange 4, the rotation center of each set of supporting sub-rods 2, and the rotation center of the cross-section of the fiberglass column 1 are all located on the common central axis of the main supporting rod 3 and the fiberglass column 1. This structure can maximize the balanced weight distribution of the fiberglass cooling tower support beam. Preferably, the supporting sub-rods 2 and the main supporting rod are made of aluminum.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
