Description

Technical Field

[0001] This utility model relates to the field of fan unit technology, specifically a new fan unit that is easy to maintain. Background Technology

[0002] In all types of buildings, whether commercial offices, industrial plants, or residential environments, ventilation systems play a crucial role. With the acceleration of urbanization and the improvement of people's living standards, the requirements for indoor air quality, temperature and humidity control, and air circulation are increasing. As the core component of the ventilation system, fan units are responsible for the transportation, circulation, and distribution of air to meet the ventilation needs of different spaces, maintain a comfortable indoor environment, and ensure the health and work efficiency of personnel. Furthermore, in some industrial production processes, specific process requirements must be met, such as controlling parameters like air cleanliness, temperature, and humidity in production areas, all of which rely on the precise operation of fan units.

[0003] The existing wind turbine drive method usually uses a motor output end to drive the shaft to rotate via a belt, and the shaft drives the fan blades to rotate. However, the belt is difficult to remove after it is tensioned, which makes it inconvenient for later maintenance and increases the maintenance cost of the wind turbine. Utility Model Content

[0004] The purpose of this utility model is to provide a fresh air handling unit that is easy to maintain and repair, and solves the problem that the belts inside the current fresh air handling units are difficult to remove and are inconvenient to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fresh air handling unit that is easy to maintain, comprising a support mechanism, the support mechanism comprising a base, a bracket provided at the top of the base, and a drive mechanism provided inside the base, the drive mechanism comprising a rotary motor, a housing covering the outer side of the output end of the rotary motor, and a first turntable provided on the output end of the rotary motor, a belt tensioned on the outer edge of the first turntable, a blower mechanism provided at the top of the base, the blower mechanism comprising a housing, a circular plate placed at the top of one side of the bracket provided inside the housing, and an adjustment mechanism provided on the outer side of the housing.

[0006] Preferably, a rotating shaft is provided on the side of the circular plate away from the support, and several fan blades are installed at equal intervals in a circular array around the outer edge of the rotating shaft.

[0007] Preferably, a drive shaft is provided on the side of the circular plate facing the bracket, and a second turntable for belt engagement is provided at one end of the drive shaft.

[0008] Preferably, the adjustment mechanism includes a limiting plate, which is a plate-shaped structure with an internal groove and fits against the side of the housing. A T-shaped slider is slidably installed inside the limiting plate, and a third turntable for tensioning a belt is provided on the slider. Two bases are symmetrically arranged on the side of the limiting plate opposite to the third turntable. A threaded rod is rotatably connected between the two bases, and one end of the threaded rod extends out of the side of the base and is provided with an adjustment mechanism.

[0009] Preferably, a drive block is helically provided on the threaded rod, the drive block is fixedly connected to the slider, and the limiting plate has a groove for the drive block to slide.

[0010] Preferably, the adjustment mechanism includes a handle, which is fixedly connected to a threaded rod, and the outer edge of the handle is provided with a plurality of gear teeth. A sliding plate is provided on the side of the handle facing the housing, and a limiting frame fixedly connected to the housing is provided on the sliding plate. One end of the sliding plate is provided with a toothed plate that engages with the gear teeth, and the other end is provided with a pull buckle on the outer side.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model comprises a rotary motor, a first turntable, a belt, a drive shaft, a second turntable, a limiting plate, a slider, and a third turntable. The first turntable at the output end of the rotary motor and the second turntable at the end of the drive shaft limit both ends of the belt. The slider, which is slidably installed inside the limiting plate, drives the third turntable to move and tensions the belt, causing it to form a triangular shape. During maintenance, the slider inside the limiting plate is moved to release the tension of the belt by the third turntable, facilitating subsequent maintenance.

[0013] 2. This utility model is designed with a handle, gear teeth, slide plate, limiting frame, toothed plate and pull buckle. By rotating the handle, the threaded rod is driven to rotate, which in turn drives the drive block to move, which in turn drives the slider to move within the limiting plate. After reaching the designated position, the pull buckle drives the slide plate to move, and the toothed plate engages with the gear teeth to limit the handle. Pulling it out releases the limit, making it easy to adjust the belt tension. Attached Figure Description
