Description

Technical Field

[0001] This utility model relates to the technical field of industrial fans, specifically to an industrial fan housing with a protective mechanism. Background Technology

[0002] Industrial fans can most efficiently drive a large amount of air movement, generating a huge air volume, creating a moving and circulating airflow field in the space, and effectively regulating the air circulation in industrial production workshops.

[0003] For example, the industrial fan housing with a protective mechanism disclosed in CN222502187U solves the problem that existing industrial fan housings with protective mechanisms generate a lot of dust, affecting workers and making normal use inconvenient. However, existing industrial fan housings with protective mechanisms, although they use mounting brackets, dustproof plates and insert pins, only rely on the dustproof plate to block the air inlet and outlet, without more detailed protective components such as protective nets. This makes it difficult to prevent small foreign objects from entering. Moreover, the dustproof plate is only fixed by the insert pin and the fixing groove, and the fixing force provided by the push spring is limited. It is easy to loosen in the complex environment of the workshop. The dustproof plate is easy to not close tightly, and dust can easily enter and adhere to the fan blades. It also cannot effectively prevent the risk of personnel accidentally touching the fan blades. The overall protective performance is weak. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing industrial fan housings with protective mechanisms cannot effectively prevent the risk of personnel accidentally touching the fan blades and have weak overall protective performance, and therefore proposes an industrial fan housing with a protective mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial fan housing with a protective mechanism, comprising an outer frame and a housing, wherein the outer wall of the outer frame is fixedly connected to the housing, the lower end of the outer frame is fixedly connected to a fixing plate, the inner wall of the fixing plate is machined with fixing holes, the inner wall of the outer frame is fixedly connected to a fixing strip, and the inner wall of the fixing strip is connected to a protective mechanism.

[0006] This feature, through the secure connection between the outer frame and the mounting plate, and the carefully designed mounting holes on the mounting plate, allows the entire industrial fan housing to be easily and firmly installed in the required location. The fixing strips inside the outer frame not only provide a stable supporting foundation for the protective mechanism, but also...

[0007] Preferably, the protective mechanism includes a mounting frame, which is threadedly connected to a fixing strip by bolts. The inner wall of the mounting frame is fixedly connected to a protective net, and the inner wall of the protective net is fixedly connected to a disc.

[0008] This feature, through the bolted connection between the mounting frame and the fixing strip, ensures that the protective mechanism can be firmly installed inside the outer frame, preventing it from loosening or falling off. The fixed connection between the protective net and the disc further enhances the strength and stability of the protective mechanism, effectively preventing accidental impacts and damage to the fan from external objects.

[0009] Preferably, the inner wall of the disc is machined with a threading hole, and the inner wall of the outer shell is connected with a reinforcing mechanism.

[0010] This feature: The wire holes machined on the inner wall of the disc not only provide a neat routing space for the fan's wires, ensuring the safety and stability of the wires during transmission, but also reduce safety hazards caused by wire friction or compression.

[0011] Preferably, the reinforcing mechanism includes an arc-shaped plate, which is threadedly connected to the outer shell by bolts, the inner wall of the arc-shaped plate is fixedly connected to a support plate, and the end of the support plate is fixedly connected to the mounting cylinder.

[0012] This feature, through the bolted connection between the arc-shaped plate and the outer casing, allows the reinforcement mechanism to be tightly and securely attached to the inner wall of the casing, effectively enhancing the structural strength of the entire industrial fan casing. The fixed connection between the inner wall of the arc-shaped plate and the support plate, as well as the fixed connection between the end of the support plate and the mounting cylinder, forms a stable triangular support structure, further improving the casing's resistance to deformation and load-bearing capacity.

[0013] Preferably, the inner wall of the mounting cylinder is machined with threaded holes.

[0014] This feature: The threaded holes machined on the inner wall of the mounting cylinder provide precise connection points for the stable installation of the fan. The tight threaded connection between the bolt and the fan not only ensures the stability of the fan during operation, but also greatly reduces noise caused by vibration, thus improving the overall user comfort.

[0015] Preferably, the inner wall of the mounting cylinder is inserted into the fan.

[0016] This feature: The insertion of the mounting sleeve into the fan ensures a tight fit between the fan and the mounting sleeve, effectively preventing abnormal noises or malfunctions caused by loosening during operation.

[0017] Preferably, the threaded hole is threadedly connected to the fan via a bolt.

[0018] This feature—the threaded connection between the threaded hole and the fan—further enhances the stability of the fan installation. This dual-protection design, combining plug-in and threaded connections, improves the smoothness of fan operation.

[0019] The present invention proposes an industrial fan housing with a protective mechanism, which has the following advantages: the outer frame is fixed to the housing, the lower end of the outer frame has a fixing plate with fixing holes for easy and stable installation, the inner wall fixing strip of the outer frame connects to the protective mechanism, the mounting frame, protective net and disc of the protective mechanism can prevent foreign object impact and accidental contact by personnel, the arc plate, support plate and mounting cylinder of the inner wall reinforcement mechanism of the housing enhance the strength of the housing and reduce fan vibration and noise, the threaded hole of the mounting cylinder is connected to the fan thread, the double fixation is more stable, and the wire hole of the disc can also organize the wires and improve the protective safety performance.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] Please see Figure 1-6 In this embodiment, an industrial fan housing with a protective mechanism includes an outer frame 1 and a housing 2. The outer wall of the outer frame 1 is fixedly connected to the housing 2. The lower end of the outer frame 1 is fixedly connected to a fixing plate 3. The inner wall of the fixing plate 3 is machined with fixing holes 4. The inner wall of the outer frame 1 is fixedly connected to a fixing strip 5. The inner wall of the fixing strip 5 is connected to a protective mechanism 6.

[0029] The protective mechanism 6 includes a mounting frame 601, which is connected to the fixing strip 5 by bolts and threads. The inner wall of the mounting frame 601 is fixedly connected to the protective net 602. Its fine mesh structure can effectively block small foreign objects from entering the fan, avoiding damage to the fan blades. It also prevents workers from accidentally touching the fan blades during operation, thus improving work safety. The inner wall of the protective net 602 is fixedly connected to the disc 603.

[0030] The outer frame 1 is fixed to the outer shell 2. The lower end of the outer frame 1 is fixed plate 3 with fixing holes 4 for easy and stable installation. The inner wall fixing strip 5 of the outer frame is connected to the protective mechanism 6. The mounting frame 601, protective net 602 and disc 603 of the protective mechanism 6 can prevent foreign object impact and accidental contact by personnel. The arc plate 801, support plate 802 and mounting cylinder 803 of the inner wall reinforcement mechanism 8 of the outer shell 2 enhance the strength of the outer shell and reduce the vibration and noise of the fan 10. The threaded hole 9 of the mounting cylinder 803 is threadedly connected to the fan 10, and the double fixation is more stable. The wire hole 7 of the disc 603 can also organize the wires and improve the protective safety performance.

[0031] The inner wall of the disc 603 is machined with wire holes 7, providing a neat routing space for the fan's wires, ensuring the safety and stability of the wires during transmission, and reducing safety hazards caused by wire friction or compression. The inner wall of the outer casing 2 is connected to a reinforcing mechanism 8, which includes an arc-shaped plate 801. The arc-shaped plate 801 is threadedly connected to the outer casing 2 by bolts, and its inner wall is fixedly connected to a support plate 802, forming a stable triangular support structure. This structure effectively enhances the structural strength of the entire industrial fan casing, improves its resistance to deformation and load-bearing capacity, reduces noise generated by vibration during fan operation, and improves overall user comfort. The end of the support plate 802 is fixedly connected to the mounting cylinder 803.

[0032] The inner wall of the mounting cylinder 803 is machined with threaded holes 9, which are connected to the fan 10 by bolts, further ensuring the stability of the fan during operation. The inner wall of the mounting cylinder 803 is inserted into the fan 10, and the threaded holes 9 are connected to the fan 10 by bolts.

[0033] Working principle:

[0034] Assembly process

[0035] Shell foundation fixing: First, fix the outer frame 1 to the shell 2 to form the main frame of the shell. Then, install the fixing plate 3 at the lower end of the outer frame 1, and use the fixing holes 4 on the inner wall of the fixing plate 3 to fix the entire shell in the designated installation position with bolts to ensure the overall stability of the shell.

[0036] Installation of the protective mechanism: Align the mounting frame 601 in the protective mechanism 6 with the fixing strip 5 on the inner wall of the outer frame 1, and connect the two with bolts to complete the initial fixing of the protective mechanism. Since the inner wall of the mounting frame 601 has been fixed to the protective net 602 and the inner wall of the protective net 602 has been fixed to the disc 603 in advance, the entire protective mechanism 6 is now installed. The wire hole 7 on the inner wall of the disc 603 can be reserved for subsequent fan wire routing.

[0037] Assembly of the reinforcement mechanism and fan: Connect the arc plate 801 of the reinforcement mechanism 8 to the inner wall of the outer shell 2 with bolts. The support plate 802 on the inner wall of the arc plate 801 is fixedly connected to the mounting cylinder 803. After the mounting cylinder 803 is installed, insert the fan 10 into the inner wall of the mounting cylinder 803. Then, with the help of the threaded hole 9 on the inner wall of the mounting cylinder 803, use bolts to connect the fan 10 to the mounting cylinder 803. Double fixing ensures that the fan 10 is installed stably. Finally, pass the fan wire through the wire hole 7 of the disc 603 to complete the wiring. The assembly is now complete.

[0038] Usage process

[0039] When in use, the airflow generated by the fan 10 can flow normally through the protective net 602. The protective net 602 can block foreign objects from entering the housing, prevent foreign objects from hitting the fan 10 and causing damage, and at the same time prevent people from accidentally touching the rotating fan 10, thus playing a safety protection role.

[0040] In the reinforcement mechanism 8, the stable structure formed by the arc-shaped plate 801, the support plate 802, and the mounting cylinder 803 can reduce the vibration generated by the fan 10 during operation, reduce noise, and enhance the overall deformation resistance of the outer shell, ensuring the structural stability of the outer shell during long-term use. If maintenance is required, the bolts in the corresponding parts can be removed to inspect or replace the protective mechanism 6, the fan 10, and other components, making the operation convenient.

[0041] 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.
