Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of container explosion-proof axial flow fan installation tools, and in particular to an exposed container explosion-proof axial flow fan installation mechanism. Background Technology
[0002] Containers are widely used in logistics, energy storage and other fields. Exposed explosion-proof axial flow fans are key components to ensure heat dissipation and ventilation of equipment inside the container. The cost, ventilation efficiency and protection performance of the installation mechanism directly affect the performance. Traditional installation mechanisms have structural design defects that make it difficult to meet the requirements of low cost, high air volume and strong sealing, and urgently need to be optimized and upgraded. Existing exposed container explosion-proof axial flow fan installation mechanisms have significant drawbacks. Traditional mechanisms typically consist of a fan base, a cover with louvers, and simple fasteners. The louver structure increases design and manufacturing complexity, leading to higher manufacturing costs. The louvers obstruct airflow channels, resulting in insufficient air intake and exhaust volume and affecting heat dissipation efficiency. The increased louver spacing, designed to improve airflow, makes the fan susceptible to rainwater infiltration in inclement weather, resulting in poor waterproof sealing performance. The sealing design at the joints of various components is rudimentary, making air leakage and water ingress problems easy to occur. Ultimately, this leads to high manufacturing costs and low ventilation efficiency. Therefore, this application designs an exposed container explosion-proof axial flow fan installation mechanism to solve the above problems. Utility Model Content

[0005] Preferably, a plurality of support members are provided between the windproof top cover and the cover plate, and the upper and lower ends of the support members are respectively fixedly connected to the windproof top cover and the cover plate.
[0006] Preferably, sheet metal connectors are fixedly installed at the four corners of the side wall of the windproof cover, a connecting plate is installed on the inner wall of the windproof top cover, and a first bolt is installed at the upper end of the connecting plate.
[0007] Preferably, sealing gaskets are provided at the connection points of the cover plate, the fan base and the windproof cover, and multiple first bolts are installed at the upper end of the cover plate and multiple second bolts are installed at the upper end of the fan base.

[0009] Preferably, the sealing gasket is made of EPDM compressed foam, and the flange gasket is made of thick silicone gasket.
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model eliminates the traditional louver structure by cooperating with the windproof top cover, support components, and cover plate, increasing the ventilation channel area, facilitating increased air intake and exhaust volume, ensuring heat dissipation efficiency, and thus achieving efficient ventilation; by cooperating with the sealing gasket and flange gasket, the EPDM compressed foam sealing gasket strengthens the sealing at the connection of the components, and the silicone flange gasket strengthens the sealing between the insect screen and the mounting hole, making it easier to block rainwater and dust intrusion, improving sealing protection, and thus achieving a strong sealing function; by cooperating with the fan base, windproof cover, and bolts, the overall structural design is simplified, the number of parts is reduced, manufacturing costs are lowered, and installation convenience is improved, thus achieving a low-cost installation function; by cooperating with the insect screen and flange gasket, the insect screen blocks mosquitoes from entering the fan, and the flange gasket ensures installation firmness and prevents the insect screen from shifting and affecting use, thus achieving an insect protection function; ultimately, it solves the problems of high manufacturing cost and low ventilation efficiency of existing mechanisms.
