Description

Technical Field

[0001] This utility model belongs to the field of fan technology, and in particular relates to a gear-driven cooling fan that is easy to maintain. Background Technology

[0002] Axial flow fans have a wide range of applications. They generate airflow in the same direction as the fan's axis, such as electric fans and air conditioner outdoor unit fans. They are called "axial flow" because the gas flows parallel to the fan's axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure. An axial flow fan is fixed in position and moves air. It mainly consists of a fan impeller and a casing, and its applications are very widespread. In some applications, it's necessary to control the fan blade speed and the width of the fan casing. This is usually controlled by a reduction gearbox. During routine use, the gearbox and fan blades need to be inspected and maintained. However, to ensure the fan's operation, a dust cover is installed. When inspecting the gearbox and fan blades, the dust cover must first be removed, which is inconvenient. Utility Model Content

[0030] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-3 As shown, a gear-driven cooling fan that is easy to maintain includes a mounting cylinder 1, a fixing frame 2, a fixing plate 3, a motor 4, a gearbox 5, fan blades 6, a protective net 7, and auxiliary components. The fixing frame 2 is fixed to the mounting cylinder with screws and has eight openings. The fixing plate 3 is fixed to the fixing frame with bolts 31. The motor 4 is fixed to the fixing plate. The gearbox 5 is connected to the fixing plate, and the motor shaft is connected to the gearbox. The fan blades 6 are fixed to the output shaft of the gearbox. The protective net 7 is fixed to the six openings of the fixing frame with screws.

[0033] Specifically, the auxiliary components include a connecting block 81, a rotating shaft 82, a fixing frame 83, a protective rod 84, and a locking component. The connecting block 81 is fixed to the mounting cylinder; one end of the rotating shaft 82 is fixed to the connecting block; two fixing frames 83 are selected and set on the remaining two openings, and they are rotatably connected to the rotating shaft; the protective rods 84 are evenly arranged on the fixing frames, and their two ends are fixed to the fixing frames respectively. When maintenance is required, the fixing frames can be rotated, thereby opening the opening of the fixing frame, which is convenient for operators to carry out maintenance. Moreover, by setting the protective rods, the air intake of the fan is not affected, and the support is improved. The protective rods can be stepped on by operators to perform maintenance and installation on the motor.

[0034] Specifically, the locking components include a pull rod 85, a pressure plate 86, a mounting plate 87, a locking rod 88, and a first elastic element 89. The pull rod 85 passes through the fixed frame and can slide relative to the fixed frame. The pressure plate 86 is fixed to the end of the pull rod and is curved in an arc. The mounting plate 87 is fixed to the fixed frame. The locking rod 88 passes through the mounting plate and can slide relative to the mounting plate. The fixed frame has a locking hole that mates with the locking rod. The first elastic element 88 is a metal spring. One end of the first elastic element is fixed to the locking rod, and the other end is fixed to the mounting plate. One end of the locking rod can abut against the pressure plate. When maintenance is not required, the fixed frame is rotated onto the fixed frame, and then the pull rod is pressed down, which in turn moves the pressure plate down. During the downward movement of the pressure plate, the locking rod is pushed to move, thereby pressing the end of the locking rod into the locking hole, so that the fixed frame is locked. When maintenance is required, the pull rod is pulled outward. Under the push of the first elastic element, the locking rod will move out of the locking hole, and then the fixed frame can be rotated. The operation is very convenient and easy to maintain.

[0035] In other embodiments, the locking component further includes a handle 91, a guide rod 92, a second elastic element 93, a push rod 94, a rubber sleeve 95, a protective protrusion 96, and a first ball bearing 97. One end of the handle 91 is fixed to the end of the pull rod; one end of the guide rod 92 is fixed to the end of the handle, and the other end passes through a fixed frame. The fixed frame has a guide hole that mates with the guide rod, and the guide rod 92 has an installation hole; the second elastic element 93 is a metal spring, one end of which is fixed in the installation hole; one end of the push rod 94 is fixed to the end of the second elastic element, and the push rod can slide relative to the inner wall of the installation hole; the rubber sleeve 95 is fitted onto the handle; the protective protrusion 96 is evenly fixed on the rubber sleeve; the first ball bearing 97 is rotatably connected to the end of the push rod, and the inner wall of the guide hole has a groove that mates with the first ball bearing; when the end of the locking rod is pressed into the locking hole, the first ball bearing is aligned with the groove, and the second elastic element pushes the first ball bearing into the groove, thereby limiting the guide rod and thus limiting the pull rod to prevent the pull rod from moving automatically.

[0036] In other embodiments, the end of the locking lever 84 is rotatably connected to a second ball bearing 841.

[0037] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed.
