Abstract
The utility model discloses an unpowered ventilation air ball, which is formed by a base, a dead axle and an air ball through general assembly. The structure of the utility model is characterized in that: each vane riveted around the air ball is provided with a rib; the upper and the lower ends of the dead axle are arranged on a rolling bearing; a lower bearing seat is designed into the shape of a circular arc-shaped conical platform with bigger upper diameter and smaller lower diameter. The vane of the utility model has big strength and can effectively prevent rain water from entering into air conduit; meanwhile, the utility model possesses simple riveting, fast assembly speed and easy assembly and disassembly.
Description
The utility model relates to a kind of improvement of unpowered air interchanger, particularly a kind of device that utilizes natural wind to quicken air-flow.
Unpowered air interchanger is the kinetic energy that utilizes hot-air to rise, and the hot humid air in building, workshop is quickened to discharge outdoor, reaching the mechanical device of ventilation cooling purpose, and its structure generally comprises the revolving body of being made up of fan blade of bearing and bearing top.The revolving body air blade intensity of prior art is little, owing to usually be subjected to the influence of irregular wind-force, causes that easily revolving body rocks again, caused the wearing and tearing of gyroaxis and the generation of fault, and its fan blade is the plane, and when rainy, rainwater can flow within doors from blade side; Its two bearing and revolving body socket, the big resistance of contact-making surface is big, can not increase wind-force.
The purpose of this utility model is at above deficiency existing unpowered air interchanger to be improved, and provides a kind of blade strength big, and water conservancy diversion rainwater not is not subject to the unpowered ventilation wind ball of extraneous windage.
The purpose of this utility model was that following technical scheme is achieved: the utility model is formed by base, fixed axis and three parts general assemblies of wind ball, the wind bag is drawn together parts such as top chock, step, roller bearing and fan blade, its design feature is to be provided with rib on every the blade that is to rivet around the wind ball, and its effect is to strengthen and anti-rainwater water conservancy diversion; The top and bottom of fixed axis all are installed on the rolling bearing; Step is designed to a circular arc frustum shape that little, the following diameter of top diameter is big.
Advantage of the present utility model is: (1) blade strength is big.The utility model is installed in the highest point in building or workshop, under the effect of the kinetic energy that the hot-air rising produces, the regular running without a break of wind ball, hot-air and moisture are discharged, because blade is provided with the triangle rib, blade strength strengthens, no matter how extraneous irregular air acts on, the wind ball can both merrily and lightheartedly rotate.(2) effectively keep out rainwater and enter the air channel.(3) riveted joint is simple, and assembling speed is fast, is easy to dismounting.
Step is designed to up big and down small shape, when air enters lonely shape frustum, and gradually little along with the frustum cross section, the dynamic pressure of air strengthens, and the air that enters endosphere obtains quickening, and the lifting height of hot-air, the speed of air-out are improved.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model; Fig. 2 is step front view of the present utility model, A-A partial schematic diagram, vertical view; Fig. 3 is that base master of the present utility model looks, B-B is to cutaway view; Fig. 4 is the utility model fan blade schematic cross-section.
The utility model is formed by base 11, fixed axis 6 and 16 general assemblies of wind ball, and wind ball 16 comprises top chock 4, step 8, rolling bearing 3 and fan blade 7.Fixed axis 6 lower ends are fixed on the base 11 by step 8, rolling bearing 3, sleeve pipe 10, and fixed axis 6 upper ends are fixed by upper sealing plate 5, top chock 4, rolling bearing 3.Blade structure is illustrated in figure 5 as waveform, water conservancy diversion rainwater not during use.
Step is designed to a circular arc frustum shape that little, the following diameter of top diameter is big, the center of frustum outer ring and bearing block, connected by four arc wing plates, the angle of arc wing plate and horizontal level is about 30 °, and the angle between the arc wing plate fin is 90 °.
During installation, the leaf blade 7 that at first will be provided with the triangle rib is riveted on the circular slab, then step 8, rolling bearing 3, sleeve pipe 10 are passed through in the lower end of fixed axis 6, add plain cushion 12, bullet pad 13, be fixed on the base 11 with nut 14, fixed axis 6 upper ends by upper sealing plate 5, top chock 4, rolling bearing 3, are added that shaft block ring 2 is fixing.
Claims (3)
1, a kind of unpowered ventilation wind ball, form by base, fixed axis and three parts general assemblies of wind ball, the wind bag is drawn together parts such as top chock, step, rolling bearing and fan blade, it is characterized in that being provided with rib on the wind ball blade, step is designed to a circular arc frustum shape that little, the following diameter of top diameter is big.
2, a kind of unpowered ventilation wind ball as claimed in claim 1 is characterized in that the top and bottom of fixed axis all are installed on the rolling bearing.
3, a kind of unpowered ventilation wind ball as claimed in claim 1, it is characterized in that step is designed to a circular arc frustum shape that little, the following diameter of top diameter is big, the center of frustum outer ring and bearing block, connect by four arc wing plates, the angle of arc wing plate and horizontal level is about 30 °, and the angle between the arc wing plate fin is 90 °.
