Description

Technical Field

[0001] This invention relates to the field of architectural design technology, and in particular to an energy-saving ventilation structure and method for architectural design. Background Technology

[0002] Ventilation structures are a key factor in ensuring air quality and comfort inside buildings. They not only provide fresh air but also help regulate indoor temperature and humidity, thereby improving the quality of life and health of residents. When designing ventilation structures, energy conservation and environmental protection requirements must be fully considered. Ventilation balls are a common type of environmentally friendly ventilation structure that uses natural wind power to achieve air circulation.

[0003] Current ventilation sphere structures are purely wind-driven and cannot function properly in the absence of natural wind or when the natural wind is weak. Furthermore, the orientation of the ventilation vents is fixed, and the prevailing wind direction and speed will vary depending on the geographical location and climate. When the ventilation vents are consistently oriented directly towards the prevailing wind direction, sand and dust may enter the building through the vents, especially in areas with severe sandstorms. This situation is particularly prominent, as sand and dust can not only pollute the indoor environment but also damage indoor furniture, appliances, and other equipment. In view of this, an energy-saving ventilation structure and method for building design is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the above problems, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide an energy-saving ventilation structure and method for building design, which solves the problems that ventilation balls cannot function in the absence of natural wind or when the natural wind is weak, and that the ventilation openings of ventilation balls are fixed in orientation after installation, making them inflexible in use.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an energy-saving ventilation structure for building design, comprising:

[0008] The main body includes a U-shaped shell with an open bottom. A rotating cylinder is provided inside the opening of the U-shaped shell. A primary connecting cylinder and a secondary connecting cylinder are fixedly connected to both sides of the rotating cylinder. The primary connecting cylinder and the secondary connecting cylinder are rotatably connected to both sides of the opening of the U-shaped shell and extend into the U-shaped shell. A wind hood and a sliding chamber are also fixedly connected to the outside of the rotating cylinder. The sliding chamber is horizontally arranged.

[0009] An exhaust assembly includes a mounting bracket, which is Y-shaped and fixedly connected at each end to the inner wall of the shroud. A rotating shaft is rotatably connected to the middle of the mounting bracket. The rotating shaft is perpendicular to the rotating cylinder and passes through the mounting bracket. A primary bevel gear is fixedly connected to one end of the rotating shaft inside the rotating cylinder, and a ventilation fan blade is fixedly connected to the other end. The axes of the rotating shaft, the primary bevel gear, and the ventilation fan blade are aligned.

[0010] The driving mechanism includes a slider slidably connected inside a rotating cylinder. Two sets of connecting strips are fixedly connected to the side of the slider closest to the rotating cylinder. These two sets of connecting strips are symmetrically arranged and extend into the rotating cylinder. Each set of connecting strips is rotatably connected to a spline sleeve, which passes through the two sets of connecting strips. A secondary bevel gear is fixedly connected to one end of each spline sleeve located between the two sets of connecting strips. The two secondary bevel gears are located on either side of the primary bevel gear and are facing each other. A wind cap is rotatably connected to one side of a U-shaped housing. The wind cap's rotating shaft passes through the outer wall of the U-shaped housing. A [missing information - likely a component or component] is fixedly connected to the side of the U-shaped housing opposite to the wind cap. The drive motor has an opening in the U-shaped housing opposite the drive motor shaft, through which the drive motor shaft passes. The wind cap and the end of the drive motor shaft are both fixedly connected to splined shafts. Two sets of splined sleeves are slidably connected to two sets of splined shafts respectively. The axes of the drive motor shaft, splined shaft, two sets of splined sleeves, two sets of secondary bevel gears, rotating cylinder, primary connecting cylinder, and secondary connecting cylinder are aligned. Both sets of secondary bevel gears can mesh with the primary bevel gear but cannot mesh with it simultaneously. The sliding chamber is rotatably connected to an adjusting screw, which horizontally penetrates the sliding chamber. The slider is threadedly connected to the adjusting screw.

[0011] The adjusting mechanism includes a worm gear. The mounting bracket is fixedly sleeved on the outside of the secondary connecting cylinder and located inside the U-shaped housing. A worm is also provided on the inside of the U-shaped housing. The worm is rotatably connected to the U-shaped housing and one end passes through the U-shaped housing. The worm and the worm gear mesh with each other.

[0012] As a preferred embodiment of the energy-saving ventilation structure for building design described in this invention, the main body further includes a dustproof net, which is fixedly connected to the inside of the hood and located above the ventilation fan blades.

[0013] As a preferred embodiment of the energy-saving ventilation structure for building design described in this invention, the driving mechanism further includes a primary handwheel, which is fixedly connected to one end of the adjusting screw.

[0014] As a preferred embodiment of the energy-saving ventilation structure for building design described in this invention, the adjustment mechanism further includes a secondary handwheel, which is disposed on the outside of the U-shaped housing and fixedly connected to the end of the worm gear.

[0015] As a preferred embodiment of the energy-saving ventilation structure for building design described in this invention, both the primary handwheel and the secondary handwheel are made of bakelite material.

[0016] As a preferred embodiment of the energy-saving ventilation structure for building design described in this invention, the driving mechanism further includes a support plate, which is disposed between two sets of connecting strips and fixedly connected to the two sets of connecting strips on both sides.

[0017] As a preferred embodiment of the energy-saving ventilation structure for building design described in this invention, the surfaces of the U-shaped shell, rotating cylinder, wind hood, and sliding chamber are all coated with anti-corrosion paint, and the wind hood is made of stainless steel.

[0018] Based on the above-mentioned energy-saving ventilation structure for building design, the present invention further provides an energy-saving ventilation method for building design, which specifically includes the following steps:

[0019] S1, the U-shaped housing is fixed to the vent position using bolts or the like;

[0020] S2, rotate the secondary handwheel, the secondary handwheel drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the secondary connecting cylinder to rotate, the secondary connecting cylinder drives the rotating cylinder to rotate, the rotating cylinder drives the fan shroud to rotate, the orientation of the fan shroud can be adjusted according to the needs;

[0021] S3. Rotating the primary handwheel drives the adjusting screw, which in turn moves the slider along the screw. The slider moves the two sets of connecting plates, which in turn move the two sets of spline sleeves. The two sets of spline sleeves then move the two sets of secondary bevel gears. When the set of secondary bevel gears closest to the vent cap meshes with the primary bevel gear, the vent cap rotates the corresponding spline shaft. The spline shaft rotates the corresponding spline sleeve, which in turn rotates the corresponding secondary bevel gear. The secondary bevel gear then rotates the primary bevel gear, which in turn rotates the primary bevel gear. The primary bevel gear, through a rotating shaft, rotates the ventilation fan blades. The vent cap is driven by wind, and the device's drive source is natural wind. When the set of secondary bevel gears closest to the drive motor meshes with the primary bevel gear, the drive motor rotates the corresponding spline shaft, which in turn rotates the corresponding spline sleeve. The spline sleeve rotates the corresponding secondary bevel gear, which in turn rotates the primary bevel gear. The primary bevel gear, through a rotating shaft, rotates the ventilation fan blades. The device's drive source is a drive motor, which can be adjusted according to the natural environment and usage requirements.

[0022] The beneficial effects of this invention are:

[0023] 1. By setting a drive mechanism with a replaceable drive source, the device can be driven by either a drive motor or by natural wind through a wind cap. Compared with ordinary ventilation balls, it solves the problem of not being able to provide ventilation when there is no natural wind or the natural wind is weak.

[0024] 2. By setting an adjustment mechanism, the orientation of the hood can be manually adjusted according to the actual situation during use. Compared with ordinary ventilation balls, this solves the problem that the ventilation opening with a fixed orientation may face the prevailing wind direction for a long time, causing sand and dust to enter the building through the ventilation opening.
