[0026] Embodiment 1

[0027] As Figures 1 - 5 shown, this embodiment discloses a detachable rotor device for a ventilator, which includes a base 1, a bracket 2, a driving motor 3, a rotor 4, and a roller mechanism 5. The base 1 is fabricated by splicing steel sections such as channel steel and steel plates, and a laser-cut and integrally formed slide rail is provided on the upper surface. The slide rail is matched with the roller mechanism 5. A connecting plate is welded below the bracket 2, and the connecting plate is detachably installed on the base 1 by bolts. The housing of the driving motor 3 is fixedly installed above the bracket 2 by bolts. The rotor 4 is coaxially arranged and fixedly connected to the output shaft of the driving motor 3. There are four groups of roller mechanisms 5, which are symmetrically arranged and fixedly installed at the four corners of the bracket 2. At the same time, the roller mechanism 5 is movably connected to the slide rail; the roller mechanism 5 includes a mounting plate 51, rollers 52, a movable plate 53, and a setscrew 54. The mounting plates 51 are symmetrically welded on the side walls of the bracket 2, and two threaded holes matching the setscrew 54 are provided on the upper surface of the mounting plate 51. The setscrew 54 passes through the threaded hole and is fixedly connected to the movable plate 53, enabling the movable plate 53 to be movably connected to the mounting plate 51. The rollers 52 are rotatably connected to the movable plate 53 through a wheel shaft and bearings; the mounting plate 51 is in an inverted U shape, and the open end is close to the base 1; a rear cover plate 6 is installed at one end of the rotor 4 away from the driving motor 3, and the rear cover plate 6 is detachably connected to the fan housing 7 by bolts.

[0028] The working principle of the detachable rotor device for a ventilator of the present utility model is as follows:

[0029] When the ventilator applying this device is in normal use, its layout is the same as that of a conventional ventilator. When disassembly and inspection are required, first remove the connecting bolts between the rear cover plate 6 and the fan housing 7, as well as the connecting bolts between the base 1 and the bracket 2. Then, use the setscrews 54 arranged on the mounting plate 51 to push the movable plate 53 downward, causing the rollers 52 to lower until the rollers 52 contact the slide rail on the upper surface of the base 1, jacking up the bracket 2, facilitating the backward movement of the entire bracket 2, and the rotor 4 can also be integrally removed from the fan housing 7, thereby implementing maintenance and repair. If necessary, the entire unit of the bracket 2, the driving motor 3, and the rotor 4 can also be towed and lifted away, replaced with spare parts, and the above steps are carried out in reverse order, and the fan equipment will return to its original state and can be put back into production use. The disassembled parts can be used as spare parts after repair, saving the time for maintenance and repair.

[0030] Embodiment 2

[0031] AsFigures 6 - 7 As shown in the figure, the difference between this embodiment and the first embodiment is that: the roller mechanism 5 includes a mounting plate 51, rollers 52, shims 55 and a jack. The mounting plate 51 is symmetrically welded to the side wall of the bracket 2. The rollers 52 are rotatably connected to the mounting plate 51 through a wheel shaft and bearings. The driving end of the jack abuts against the lower end surface of the bracket 2 by means of a support member. The shims 55 are matched with the slide rail and are movably arranged in the slide rail. When the fan equipment is in normal use, part of the rollers 52 extends into the slide rail and does not contact the base 1. When disassembly and assembly are required, first remove the connecting bolts between the rear cover plate 6 and the fan housing 7, and the connecting bolts between the base 1 and the bracket 2. Then use the jack to lift the bracket 2, and at the same time pad the matching shims 55 into the slide rail to support the rollers 52, and flexibly remove the rotor 4 by means of the rollers 52, realizing the same easy disassembly and assembly function as in the first embodiment; the rest of the technical features are the same.

[0032] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
