This combined vibration-damping fan belt cover, through its modular shell design and the synergistic effect of reinforcing components, not only suppresses vibration at its source but also controls its propagation along its path, significantly improving the structure's vibration resistance and overall stability. It possesses excellent engineering application value and promising prospects for widespread adoption. This embodiment of the invention utilizes a protective cover structure composed of a first shell, a second shell, a third shell, and a fourth shell, along with reinforcing components positioned between each shell. This achieves detachable connections between the shells, not only enhancing the overall structural strength and vibration resistance but also effectively dispersing vibration stress during operation, reducing noise, decreasing equipment failure rates, and improving the stability and reliability of equipment operation, thereby extending equipment lifespan. Simultaneously, the modular shell structure facilitates on-site installation, disassembly, and partial replacement, improving maintenance efficiency and structural adaptability, accelerating the installation and disassembly of the protective cover, and reducing equipment maintenance time.

[0048] In industrial environments, especially in painting workshops, large fans are commonly used in the air supply and exhaust systems of spray booths. These fans are equipped with belt drives, and the belt covers, as key components protecting these moving parts, are crucial for the safe operation of the equipment. However, current fan belt covers on the market generally suffer from excessive vibration, leading to increased equipment failure rates and more frequent maintenance.

[0049] After careful investigation, the applicant discovered that existing wind turbine belt covers typically consist of three parts: an outer plate, a front cover, and a rear cover. The outer plate lacks a supporting structure in the middle, making it prone to deformation during operation and resulting in severe vibration. This vibration exacerbates friction between the belt and the belt cover, accelerating belt wear and shortening its lifespan; it also generates higher noise levels, worsening the working environment.

[0050] Furthermore, the existing wind turbine belt covers are large and integrated, making disassembly and reinstallation complex and time-consuming during maintenance or component replacement. This not only increases downtime but also raises maintenance costs. The inconvenience of disassembly also limits the efficiency of inspecting and maintaining internal components, increasing the difficulty of troubleshooting. Moreover, the traditional belt cover design uses enclosed front and rear covers, reducing airflow and hindering temperature reduction. In high-temperature environments, the performance of the belt and other components is affected, potentially leading to premature aging or failure. Poor heat dissipation also indirectly exacerbates vibration problems, as increased temperature causes material expansion, altering the dimensional stability of the belt cover and triggering additional mechanical stress and vibration.

[0051] In summary, the existing design of the fan belt cover has significant shortcomings in vibration damping and is also detrimental to equipment maintenance and heat dissipation. These problems are interconnected and collectively affect the overall performance and service life of the equipment.

[0052] The main purpose of this invention is to propose a combined vibration-damping fan belt cover to solve the problem of how to improve the vibration resistance of the fan belt cover.

[0053] Please see Figures 1 to 3 In one embodiment of this utility model, the combined vibration-damping fan belt cover 100 includes a protective cover 1 and a reinforcing mechanism 2. The protective cover 1 is provided with a receiving cavity (not shown in the figure). The protective cover 1 includes a first housing 11, a second housing 12, a third housing 13, and a fourth housing 14. The first housing 11 and the second housing 12 are arranged sequentially along a first direction, the first housing 11 and the fourth housing 14 are arranged sequentially along a second direction, and the second housing 12 and the third housing 13 are arranged sequentially along a second direction. The first direction and the second direction are perpendicular to each other. The reinforcing mechanism 2 includes a first reinforcement... The first housing 11 is detachably connected to the second housing 12 via the first reinforcing component 21, the second housing 12 is detachably connected to the third housing 13 via the second reinforcing component 22, the third housing 13 is detachably connected to the fourth housing 14 via the third reinforcing component 23, and the fourth housing 14 is detachably connected to the first housing 11 via the fourth reinforcing component 24, so that the first housing 11, the second housing 12, the third housing 13, and the fourth housing 14 enclose and form a receiving cavity.

[0054] In the embodiments of this utility model, such as Figure 1As shown, the first direction is left-right, and the second direction is up-down. The protective cover 1 provides physical isolation and protection for the belt drive components of the fan. This protective cover 1 adopts a modular design, splitting the original monolithic structure into four independent shells: a first shell 11 and a fourth shell 14 mounted on the fan pulley, and a second shell 12 and a fourth shell 14 mounted on the motor pulley. These shells are assembled and disassembled, solving the problem of the traditional bulky and inconvenient disassembly of fan belt cover structures. This not only improves the flexibility and versatility of the structure but also effectively reduces the area of ​​a single panel, thereby reducing the vibration response caused by the bending deformation of large-area panels during vibration, fundamentally mitigating the vibration amplitude of the structure. To further enhance the structure's vibration resistance, the protective cover 1 also welds reinforcing components onto each shell. These reinforcing components are rationally arranged according to the main vibration direction of the fan during operation, improving the connection strength and overall rigidity between shells. They also effectively disperse vibration stress during operation, reduce noise, and improve the stability and reliability of the equipment. Furthermore, the detachable connections between the various housings support modular installation and partial replacement, improving the convenience of on-site operation and maintenance efficiency. This combined vibration-damping fan belt cover 100, through its split housing design and the synergistic effect of reinforcing components, not only suppresses vibration at its source but also controls its propagation along its path, significantly improving the structure's vibration resistance and overall stability. It possesses excellent engineering application value and promising prospects for widespread adoption.

[0055] The technical solution of this utility model, through the protective cover 1 structure composed of a first shell 11, a second shell 12, a third shell 13, and a fourth shell 14, and in conjunction with the reinforcing components set between each shell, achieves detachable connection between the shells. This not only improves the overall structural strength and vibration resistance, but also effectively disperses vibration stress during operation, reduces noise, reduces equipment failure rate, and improves the stability and reliability of equipment operation, thereby extending the service life of the equipment. At the same time, the modular shell structure also facilitates on-site installation, disassembly, and partial replacement, improving maintenance efficiency and structural adaptability, accelerating the installation and disassembly speed of the protective cover 1, and reducing equipment maintenance time.

[0056] Please see Figure 1 and Figure 3In one embodiment, the first housing 11 includes a first cover plate 111 and a first front baffle 112 and a first rear baffle 113 spaced apart on the first cover plate 111 along a third direction. The second housing 12 includes a second cover plate 121 and a second front baffle 122 and a second rear baffle 123 spaced apart on the second cover plate 121 along a third direction. At least one of the first front baffle, the first rear baffle, and the first cover plate 111 is detachably connected to the fourth housing 14 via a fourth reinforcing component 24. At least one of the two rear baffles 123 and the second cover plate 121 is detachably connected to the third housing 13 via the second reinforcing assembly 22, wherein the first direction, the second direction, and the third direction are perpendicular to each other; the first front baffle 112 is detachably connected to the second front baffle 122 via the first reinforcing assembly 21; and / or, the first rear baffle 113 is detachably connected to the second rear baffle 123 via the first reinforcing assembly 21; and / or, the first cover plate 111 is detachably connected to the second cover plate 121 via the first reinforcing assembly 21; specifically, as Figure 3 As shown, the third direction is the front-to-back direction, and the first direction, the second direction, and the third direction are perpendicular to each other, forming a three-dimensional structural layout. The first shell 11 and the second shell 12 can be detachably connected in various ways. For example, the first front baffle 112 can be connected to the second front baffle 122 through the first reinforcing component 21, or the first rear baffle 113 can be connected to the second rear baffle 123 through the first reinforcing component 21, or the first cover plate 111 can be connected to the second cover plate 121 through the first reinforcing component 21. Any one of the three can be selected or used in combination to achieve a stable connection and structural adaptability between the first shell 11 and the second shell 12. Similarly, the second housing 12 and the third housing 13 can be connected by one or a combination of the second cover plate 121, the second front baffle 122, and the second rear baffle 123 in conjunction with the second reinforcing component 22. Similarly, the first housing 11 and the fourth housing 14 can be connected by one or a combination of the first cover plate 111, the first front baffle 112, and the first rear baffle 113 in conjunction with the fourth reinforcing component 24. This structure not only enhances the connection strength between the housings through reinforcing components, improving overall rigidity and vibration resistance, but also supports rapid installation and partial replacement through modular design, improving the convenience of on-site operation and maintenance efficiency. Furthermore, the design of multiple optional connection points enhances the flexibility of the structure, allowing for optimized layout based on the actual vibration direction and installation environment, further improving the stability and adaptability of the protective cover 1.

[0057] Please see Figures 1 to 3In one embodiment, the first reinforcing component 21 includes a first longitudinal reinforcing member 211, a second longitudinal reinforcing member 212, and a first axial reinforcing member 213. The first longitudinal reinforcing member 211 and the second longitudinal reinforcing member 212 both extend along a second direction, and the first axial reinforcing member 213 extends along a third direction. The first front baffle 112 is detachably connected to the second front baffle 122 through the first longitudinal reinforcing member 211, and the first rear baffle 113 is detachably connected to the first rear baffle 113 through the second longitudinal reinforcing member 212. The first cover plate 111 is detachably connected to the second cover plate 121 through the first axial reinforcing member 213. Specifically, the first longitudinal reinforcing member 211 and the second longitudinal reinforcing member 212 extend along the second direction, which can effectively enhance the connection strength between the first housing 11 and the second housing 12 in the vertical direction, improve the overall rigidity of the structure, and at the same time, when the fan encounters vibration in the vertical direction during operation, the vibration stress can be dispersed to a larger range through the two longitudinal reinforcing members to avoid local stress concentration. The first axial reinforcing member 213 is arranged along a third direction to connect the first cover plate 111 and the second cover plate 121, providing support in the front-to-back direction, enhancing the stability of the structure in the height direction, and playing a buffering and absorption role when vibration occurs in this direction. The detachable connection between each reinforcing member and the corresponding shell member not only facilitates on-site installation and partial replacement, but also provides flexible space for structural maintenance and functional optimization, further improving the ease of use and engineering applicability of the protective cover 1.

[0058] Please see Figure 6In one embodiment, the first axial reinforcing component 213 includes a first support plate 2131, a second support plate 2132, a first connecting plate 2133, and a second connecting plate 2134. The first support plate 2131 is connected to the first cover plate 111. The first connecting plate 2133 is disposed on the side of the first support plate 2131 away from the fourth housing 14. The second support plate 2132 is connected to the second cover plate 121. The second connecting plate 2134 is disposed on the side of the second support plate 2132 away from the third housing 13. The first connecting plate 2133 and the second connecting plate 2134 are detachably connected. Specifically, the first support plate 2131 and the second support plate 2132 are fixedly connected to the first cover plate 111 and the second cover plate 121, respectively, which significantly improves the load-bearing capacity and vibration resistance of the protective cover 1 in the third direction and prevents structural deformation or resonance caused by the vibration of the fan operation. The first connecting plate 2133 and the second connecting plate 2134 mainly realize the connection function between the first cover plate 111 and the second cover plate 121, ensuring that the protective cover 1 maintains a stable connection in the assembled state and preventing relative displacement. This structure is rationally designed with clear functional division, combining the advantages of structural reinforcement and modular connection. It has advantages such as reliable connection, good vibration resistance, and easy maintenance, making it suitable for large-scale wind turbine belt cover applications with high strength and maintainability requirements. Furthermore, in this embodiment, the first support plate 2131 is welded to the first cover plate 111, and the second support plate 2132 is welded to the second cover plate 121. This structure achieves a fixed connection between the support plate and the cover plate through welding, enhancing the structural strength and stability of the connection part, effectively transferring loads and improving the rigidity of the overall structure. Moreover, the welding connection process is mature and reliable, suitable for structural connections within modules that do not require frequent disassembly, while providing a solid foundation for subsequent detachable connections. This design not only improves the vibration resistance and structural durability of the wind turbine belt cover, but also has the advantages of simple manufacturing process, low cost and strong applicability, making it suitable for large wind turbine belt cover applications with high requirements for strength and stability.

[0059] Please see Figure 6In one embodiment, the first connecting plate 2133 includes a plate body 21331, a bolt 21332, and a nut 21333. The plate body 21331 has a first mounting hole 21331a, and the second connecting plate 2134 has a second mounting hole 2134a. The bolt 21332 passes through the first mounting hole 21331a and the second mounting hole 2134a and engages with the nut 21333 via a threaded connection, thereby restricting the movement of the plate body 21331 relative to the second connecting plate 2134. Specifically, this structure achieves a reliable fixed connection between the first connecting plate 2133 and the second connecting plate 2134 through the locking action of the bolt 21332 and the nut 21333, offering advantages such as strong connection, convenient assembly and disassembly, and strong adaptability. The mounting holes facilitate alignment and assembly, improving on-site installation efficiency. This connection method effectively prevents loosening caused by fan vibration, enhancing the overall stability and vibration resistance of the structure. This structure is suitable for axial reinforcement connections between multiple modules in a wind turbine belt cover and has good engineering application value.

The asymmetrical arrangement can achieve precise configuration of structural reinforcement according to the actual stress conditions, avoiding material waste and improving reinforcement efficiency. In addition, this arrangement helps to disperse stress concentration and prevent structural deformation or cracking caused by excessive local stress.
