The wind-force power generation box that interlocks

Technical field:

The utility model relates to the wind generating unit technical field, particularly a kind of wind-force power generation box that interlocks.

Background technique:

Wind-power electricity generation utilizes the wind wheel blade capturing wind energy of wind generating unit, and is converted into rotating mechanical energy, and then drives generator for electricity generation.There is huge freeway net in China, and its night illumination has expended huge electric energy.At present, the street lamp that utilizes solar energy, natural wind energy generating is arranged, slowed down the anxiety of electricity consumption on the expressway to a certain extent, but it is bigger that this class street lamp is influenced by weather condition, can not power sustainedly and stably, in case interruption of power supply can be brought very big threat to driving.On expressway, the automobile wind energy of bringing of speeding by is very abundant, and the air-flow that utilizes high speed wagon flow seething on the expressway to cause generates electricity, and can effectively remedy the deficiency of solar energy, natural wind energy generating.The patent No. is 200720030045.9 Chinese patent " a kind of expressway wind generating unit ", disclose the device that a kind of air-flow that utilizes high speed wagon flow seething on the expressway to cause generates electricity, it comprises bearing, impeller, impeller chimney, gearwheel, microgenerator, circuit board, support, storage battery, small gear, expressway guardrail.The expressway guardrail is installed impeller through fluting processing back, and impeller links to each other with microgenerator through speed change gearwheel, small gear, after the circuit rectification on the output current process circuit board of microgenerator, the filtering to charge in batteries.But this apparatus structure complexity, impeller are caught a little less than the wind energy power, can not effectively catch the aerodynamic force energy that vehicle takes up.

The model utility content:

The purpose of this utility model is to provide a kind of wind-force simple in structure, that generating efficiency is high staggered power generation box at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technological scheme:

The wind-force power generation box that interlocks, comprise housing, impeller, rotating shaft and exhaust outlet, impeller is fixed in the housing, rotating shaft is connected with impeller, exhaust outlet is opened on the housing, and described housing is provided with two intake grills at least, and intake grill is the center with the center of housing, the setting that is centrosymmetric, intake grill is scroll casing shape.

Wherein, described impeller comprises a wheel shaft, and wheel shaft is connected with rotating shaft, and wheel shaft periphery extended loop is wound with a plurality of flabellums that are radial arrangement.

Wherein, described flabellum has a windward side and a lee face.

Wherein, described windward side is concavity, and lee face is convex.

Wherein, described exhaust outlet is evenly distributed on the lower wall of housing.

Wherein, described exhaust outlet is evenly distributed on the upper wall of housing.

Wherein, described rotating shaft is fixed with a base, and it is conical that base is.

Wherein, microgenerator and storage battery are installed in the described base, the running shaft of microgenerator is connected with rotating shaft.

The utility model beneficial effect is: the utility model comprises housing, impeller, rotating shaft and exhaust outlet, impeller is fixed in the housing, rotating shaft is connected with impeller, exhaust outlet is opened on the housing, described housing is provided with two intake grills at least, intake grill is the center with the center of housing, the setting that is centrosymmetric, and intake grill is scroll casing shape.Because intake grill is the center with the center of housing, settings that be centrosymmetric can catch that automobile drives fast back and forth and the air-flow that brings different direction, and it is strong to catch wind energy power, makes housing maintenance better balance performance simultaneously, alleviates the impact that wind-force brings housing; Intake grill is scroll casing shape, and mouthful big abdomen is little, is gradually closing shape air channel, can concentrate wind-power electricity generation, and the utility model is simple in structure, generating efficiency is high.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see accompanying drawing 1-3, the utility model comprises housing 1, impeller 2, rotating shaft 3 and exhaust outlet 4, impeller 2 is fixed in the housing 1, and rotating shaft 3 is connected with impeller 2, and exhaust outlet 4 is opened on the housing 1, described housing 1 is provided with two intake grills 5 at least, intake grill 5 is the center with the center of housing 1, the setting that is centrosymmetric, and intake grill 5 is scroll casing shape.Because intake grill 5 is the center with the center of housing 1, settings that be centrosymmetric can catch that automobile drives fast back and forth and the air-flow that brings different direction, and it is strong to catch wind energy power, makes housing 1 maintenance better balance performance simultaneously, alleviates the impact that wind-force brings housing 1.Intake grill 5 is scroll casing shape, and mouthful big abdomen is little, is gradually closing shape air channel, can concentrate wind-power electricity generation, the generating efficiency height.A base 10 is fixed in rotating shaft 3, it is conical that base 10 is, and microgenerator and storage battery are installed in the base 10, and the running shaft of microgenerator is connected with rotating shaft, the rotating power of impeller 2 is passed to microgenerator by rotating shaft 3, and microgenerator is to be stored in the storage battery behind the electric energy with wind energy transformation.

The described impeller 2 of present embodiment comprises a wheel shaft 6, and wheel shaft 6 peripheral extended loops are wound with a plurality of flabellums 7 that are radial arrangement, and the wind energy induced force is strong, even can start impeller 2 rotations under the very low breeze conditions of wind speed.When wind-force drives flabellum 7 rotations, its peripheral air will be driven to air-flow because of the rotation of impeller 2.

The described flabellum 7 of present embodiment has a windward side 8 and a lee face 9, and windward side 8 is concavity, and lee face 9 is convex.Concavity windward side 8 can obtain the suitable angle that facings the wind, and aerodynamic characteristics is good, suppresses flow shedding flabellum 7, promotes the generation of eddy current.When air-flow is close to flabellum 7 Surface runoff, on the one hand can produce augmented thrust, can reduce flabellum 7 on the other hand and be subjected to wind and cut influence to promote its stability, improve rotary motive power, increase wheel shaft 6 rotating speeds, strengthen wind-force; Convex lee face 9 can make the air-flow that radially sucks more level and smooth under high strength wind-force, can avoid air-flow to impact mutually, offset.

The utlity model has a plurality of exhaust outlets 4, exhaust outlet 4 is evenly distributed on the upper and lower wall of housing 1, and weak air-flow and disturbing flow can in time be drained, and reduces the influence that resistance and disturbing flow bring.

The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
