Abstract
The utility model provides micro wind tunnel generators used in a building roof truss. In the natural ventilation places of the building, air inlets and air outlets are connected by ventilation ducts, a plurality of micro generators are arranged in the ventilation ducts, when wind comes into the ducts, the wind is extruded and begins accelerating turning of fan blades of the generators to drive the generators to generate direct current which is connected to inverters or storage batteries for standby use as required. The micro wind tunnel generators are installed in the positions where wind tunnel effect will be generated, in the buildings and the peripheral parts in a hidden manner, thus supplementing the electricity needed in the buildings without affecting the appearances. The micro wind tunnel generators have low cost, are simple and easy to install, take full advantage of the natural wind, a clean energy, and realize conversion from wind energy to electric energy.
Description
Technical field
The utility model relates to the building field, is specifically related to a kind of miniature wind-tunnel generator in the roof truss that is used to build.
Background technique
Micro wind turbine generator, utilization every household, between the gable of building roof system (frame) or eaves, the natural wind of cornice and position, body of wall jointing place formation, a large amount of wind energies that wind-tunnel contains.
General artificial wind tunnel test is widely known by the people, and a lot of wind-driven generators are built wild country, deserted mountain or sea in, and the cost high investment is big, and institute's electricity needs electrical network to cooperate.Yet the natural wind that the building structure of every household itself forms fails to be used, and has caused the waste of the energy.
The model utility content
According to wind-tunnel (WIND TUNNEL) theory; For roof structure; Wind load bodily form coefficient and wind fluttering factor are analyzed wind field, and phase mutual interference enhancement coefficient windward side gable ventilates when natural ventilation is provided, if connect meeting generation wind tunnel effect to exhaust outlet with pipe type (circular or square all can); In like manner the eaves lower end also can produce effect same, minisize axial-flow formula wind-driven generator is set can produces reasonable effect if use.China's blast is wide by the area of application scope of meeting standard in 50 years; Therefore the architectural design stage and confirm towards the time ingenious being applied and reserved location; Drop into to install by stages in the future that to act according to one's capability according to individual financial resources be a ring in the low-carbon (LC) life, income for a short time has high input.
The utility model is used to build the miniature wind-tunnel generator in the roof truss; The utilization microgenerator is installed in the building and the peripheral position that partly can produce wind tunnel effect with the mode of hiding, thereby does not influence outward appearance; Replenish required electric power in the building; The utility model cost is low, installation is simple and easy, has made full use of this clean clean energy resource of natural wind, realizes the conversion of wind energy and electric energy.To achieve these goals, the utility model is realized through following technological scheme: when the building construction roof system, drive air port and exhaust outlet at two ends, gable position and form blast, intake grill is connected with ventilation duct with exhaust outlet; Generator is set in the ventilation duct, and said generator comprises fan blade, when wind is blown in the pipe; Wind speed is squeezed and begins to accelerate the fan blade rotation of generator; Drive generator for electricity generation, generating produces direct current, inserts when inverter or storage battery need fully and uses.
As a kind of preferred version of the utility model, said intake grill is positioned at the windward side of gable, house eaves or the eaves lower end of roof truss, and said exhaust outlet is positioned at the adverse wind face of gable, house eaves or the eaves lower end of roof truss.
As a kind of preferred version of the utility model, said ventilation duct is circular or square.
As a kind of preferred version of the utility model, said ventilation duct adopts galvanized sheet, and said galvanized sheet thickness is 0.5mm.
As a kind of preferred version of the utility model, piecewise uniform is provided with generator in the said ventilation duct.
As a kind of preferred version of the utility model, said generator is the minisize axial-flow generator.
As a kind of preferred version of the utility model, the fan blade diameter of said generator is 350mm.
As a kind of preferred version of the utility model, said wind-tunnel generator adopts horn-like several intake grills that insert simultaneously, forms bigger wind-tunnel.
Through the electric energy that the utility model produces, not only can realize homebrew, the electricity of saving can also be supported commercial production, and effects of energy saving and emission reduction is big.The utility model has changed the thinking and the application of wind-power electricity generation, is not to have only office of the state and large enterprise or government to support could adopt and utilize clean energy resource the scope of where distinguishing in office from now on; Any building all can be used according to the miniature wind tunnel device wind-power electricity generation of fluid mechanics and BUILDINGS MODELS generation, especially is concealed in building, can not influence profile; It is convenient again maintenance attractive in appearance; With low cost, indoors do not expose to the sun and rain, thereby prolonged working life.
Description of drawings
Fig. 1 is the utility model wind-tunnel generator Structure schematic representation.
Fig. 2 is the application schematic representation of the utility model wind-tunnel generator.
Reference character: 1. intake grill, 2. exhaust outlet, 3. minisize axial-flow generator, 4. ventilation duct, 5. fan blade.
Embodiment
Below in conjunction with accompanying drawing the concrete structure of the utility model is explained.
Please combine Fig. 1 and Fig. 2, the utility model, the two ends below gable and eaves are driven air port 1 and exhaust outlet 2 into; Intake grill 1 is connected with square ventilation duct 4 with exhaust outlet 2, and it is the galvanized sheet of 0.5mm that ventilation duct adopts thickness, and piecewise uniform is provided with 3 minisize axial-flow generators 3 in the ventilation duct 4; Fan blade 5 diameters that minisize axial-flow generator 3 comprises are 350mm; When wind is blown in the ventilation duct 4, the wind speed fan blade 5 that begins to accelerate generator 3 that is squeezed is rotated, and drives generator 3 generatings; Generating produces direct current, inserts when inverter or storage battery need fully and uses.
