In order to solve the problems of the technologies described above, the utility model provides a kind of circular hood generator, it comprises fixing vertical rod, circular hood, impeller and the live axle be connected with wind mill rotor, described circular hood is arranged on described fixing vertical rod upper end and can rotates around fixing vertical rod axis, described circular hood is provided with and communicates each other and all have air-inlet cavity and the air-out chamber of flare openings, joint between described air-inlet cavity and air-out chamber is throat structure, it is inner that described impeller is installed in rotation on described air-out chamber by impeller shaft, described impeller shaft is connected with described live axle by driving mechanism.
As preferably, described impeller is at least provided with two, wherein has two described impellers to be installed in rotation on the symmetrical both sides of inside, described air-out chamber respectively by impeller shaft.
As preferably, described impeller shaft is in vertically arranging, and its two ends are rotatably connected with the upper and lower wooden partition of described circular hood respectively.
As preferably, described live axle is in vertically arranging, and on its one end and described circular hood, wooden partition is rotatably connected.
As preferably, described driving mechanism is the outside that belt gear is arranged at described circular hood, and described driving mechanism comprises the first belt pulley be connected with described impeller shaft one end and is connected with described live axle one end and and the second belt pulley of arranging of described first belt pulley homonymy and the belt that is in transmission connection between described first belt pulley and the second belt pulley.
As preferably, the area of the flare openings of described air-inlet cavity is greater than the area of the flare openings in described air-out chamber.
Implement a kind of circular hood generator of the present utility model, compared with prior art, there is following beneficial effect: the utility model is by the design of above-mentioned circular hood, can large-area wind be drawn in the air-inlet cavity become gradually, concentrate and blow to the impeller being arranged on inside, air-out chamber, improve the density of wind energy, wind speed can be enhanced about more than once, and then improve the utilization ratio of wind energy, this device can be generated electricity in gentle breeze situation.In addition, the utility model takes live axle rotation to by arranging multiple impeller, can provide larger moment, be applicable to Electricity Generation unit for live axle.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme of the utility model embodiment, be briefly described to the accompanying drawing of embodiment below.
Fig. 1 is the structural representation of circular hood generator one preferred embodiment that the utility model provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, an embodiment of the present utility model, a kind of circular hood generator, it comprises fixing vertical rod 1, circular hood 2, impeller 3 and the live axle 4 be connected with wind mill rotor, described circular hood 2 is arranged on described fixing vertical rod 1 upper end and can rotates around fixing vertical rod 1 axis, described circular hood 2 is provided with and communicates each other and all have air-inlet cavity 21 and the air-out chamber 22 of flare openings, joint between described air-inlet cavity 21 and air-out chamber 22 is throat structure, it is inner that described impeller 3 is installed in rotation on described air-out chamber 22 by impeller shaft 31, described impeller shaft 31 is connected with described live axle 4 by driving mechanism.Thus, the utility model is by the design of above-mentioned circular hood 2, large-area wind can be drawn in the air-inlet cavity 21 become gradually, concentrate and blow to the impeller 3 being arranged on inside, air-out chamber 22, improve the density of wind energy, wind speed can be enhanced about more than once, and then improve the utilization ratio of wind energy, this device can be generated electricity in gentle breeze situation.
Described impeller 3 is at least provided with two, wherein has two described impellers 3 to be installed in rotation on the symmetrical both sides of inside, described air-out chamber 22 respectively by impeller shaft 31.Concrete, described impeller shaft 31 is in vertically arranging, and its two ends are rotatably connected with described circular hood about 2 wooden partition respectively.Described live axle 4 is in vertically arranging, and on its one end and described circular hood 2, wooden partition is rotatably connected.Described driving mechanism is the outside that belt gear is arranged at described circular hood 2, and described driving mechanism comprises the first belt pulley 5 be connected with described impeller shaft 31 one end and is connected with described live axle 4 one end and and the second belt pulley 6 of arranging of described first belt pulley 5 homonymy and the belt 7 that is in transmission connection between described first belt pulley 5 and the second belt pulley 6.Thus, the utility model takes live axle 4 to rotate by arranging multiple impeller 3, can provide larger moment, be applicable to Electricity Generation unit for live axle 4.
Owing to considering the change of wind direction, described circular hood 2 freely can rotate around fixing vertical rod 1 axis, flare openings direction in order to ensure air-inlet cavity 21 can adapt to ground automatically to side windward, and the area of the flare openings of described air-inlet cavity 21 is greater than more than the area twice of the flare openings in described air-out chamber 22.
