Problems solved by technology
[0004] The purpose of the present invention is to provide a helicopter axial flow fan that is easy to disassemble and replace in order to solve the above problems. Adjust up, down, left, and right, and the direction of blowing cannot be adjusted. Not only that, but because the external protective shell is inconvenient to disassemble, it is very inconvenient to disassemble and replace the internal fan.

Embodiment Construction
[0027] Such as Figure 1-8 As shown, the present embodiment adopts the following technical solutions: a helicopter axial flow fan that is easy to disassemble and replace, including a fan body 1, the air inlet of the fan body 1 is equipped with a dust-proof net 2, and the dust-proof net 2 can block The dust and sundries brought by the airflow can prevent dust and sundries from entering the fan body 1. The dust-proof net 2 is fitted at the air inlet of the fan body 1. The side of the dust-proof net 2 is connected with a fixed frame 3, and the fan body 1 Both ends of the air inlet are connected with a limit mechanism 4, and the limit mechanism 4 includes an arc block 41, and the ends of the two arc blocks 41 are connected with several insert blocks 42, when it is necessary to overhaul the inside of the fan body 1 At this time, the first spring 44 is compressed by pulling the arc-shaped blocks 41 of the two limit mechanism 4, and the plug-in block 42 connected by the two arc-shape...

The invention discloses a helicopter axial flow fan which is easy to disassemble and replace. The side is connected with a fixed frame, and the two ends of the air inlet of the fan body are connected with a limit mechanism. The limit mechanism includes an arc block. A direction adjustment mechanism is provided, and the beneficial effects achieved by the present invention include: the fan body on the support frame at the upper end of the center column can be driven to rotate left and right, and can be adjusted up, down, left, and right to adjust the direction of blowing. The present invention is provided with a limit mechanism. When checking and repairing the inside of the fan body, pull the arc-shaped blocks of the two limit mechanisms. When the inserting block is separated from the socket, the fixed frame of the dust-proof net can be separated from the fixing of the inserting block, and the dust-proof net can be taken out for cleaning, which is convenient. Disassembly can also be used to overhaul the inside of the fan body.
Description
Technical field: [0001] The invention belongs to the technical field of aircraft ventilation equipment, and in particular relates to a helicopter axial flow fan which is easy to disassemble and replace. Background technique: [0002] Helicopter axial fan refers to the equipment that the gas flows parallel to the fan shaft. The axial fan is generally composed of an impeller and a protective shell. The rotation of the impeller makes the air flow, which can not only ventilate the interior of the aircraft, but also play a role in air circulation. cooling effect. [0003] Under the existing technology, when the axial flow fan of the helicopter is used, the axial flow fan is generally fixed on the shelf, and cannot be adjusted up, down, left, and right, and the direction of blowing cannot be adjusted. Not only that, because the external protective shell does not It is convenient to disassemble, which makes it very inconvenient when the internal fan needs to be disassembled and re...
