Abstract
The utility model relates to a wind driven generator, in particular to a rotatable rudder of the wind driven generator. The rotatable rudder comprises fan blades mounted at the front end of the wind driven generator, a rudder body mounted at the rear end of the wind driven generator and fixedly connected with the wind driven generator through a connecting rod, and a stand column supporting the wind driven generator. The rotatable rudder is characterized in that the wind driven generator is sleeved with a cylindrical wind collecting hood, a windward opening at the front end of the cylindrical wind collecting hood is opposite to the fan blades, a wind outlet is formed in the rear end of the cylindrical wind collecting hood, one end of the tubular connecting rod is communicated with the wind outlet, a long groove is formed in the other end of the tubular connecting rod in the axial direction, the rudder body is inserted to the long groove, and the upper end of the stand column is connected with the cylindrical wind collecting hood. The rotatable rudder has the advantages that the temperature of the wind driven generator can be effectively lowered, the service life of the wind driven generator is prolonged, force on the fan blades from the wind can be effectively improved, and the fan blades can be driven to rotate under a breeze state.
Description
Technical field
The utility model relates to the rotatable rudder of a kind of wind-driven generator, particularly wind-driven generator.
Background technique
Along with scientific and technological development grows with each passing day to the demand of electric power, and a large amount of exploitations of fossil energy are increasing on the impact of environment.The utilization of renewable energy sources becomes a developing direction that solves energy shortage and environmental pollution.In the very inaccessible areas of conventional electrical network such as some outlying mountain areas, farming and pastoral areas, small-size wind power-generating equipment, because it is easy to use, invest the features such as little, is applied gradually at present.But existing small-sized wind power generator is under the lower situation of wind speed, and the rudder on wind-driven generator cannot make to drive the fan blade surface of revolution of generator rotation vertical with the movement direction of wind, causes generating efficiency to reduce.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, provides a kind of in the situation that wind speed is lower, can make in wind-driven generator the surface of revolution of fan blade and the movement direction of wind vertical, can effectively increase the rotatable rudder of wind-driven generator of generating efficiency.
The technical solution of the utility model is: the rotatable rudder of a kind of wind-driven generator, comprise and be arranged on the fan blade of wind-driven generator front end and be arranged on the rudder that wind-driven generator rear end is fixedly linked by connecting rod, and the column of support wind-driven generator, it is characterized in that there is tubular wind-collection cover at above-mentioned wind-driven generator overcoat, tubular wind-collection cover front end windward mouth is relative with fan blade, rear end has exhaust outlet, one end of tubulose connecting rod is connected with exhaust outlet, the other end has the elongated slot along its axis, rudder is inserted in elongated slot, column upper end is connected with tubular wind-collection cover.
Above-mentioned tubular wind-collection cover windward mouth is horn-like.
The end face of the above-mentioned side pipe shape connecting rod being connected with rudder is closed state.
The technical solution of the utility model has following characteristics:
1, owing to having tubular wind-collection cover at wind-driven generator overcoat, can effectively reduce the temperature of wind-driven generator, extend the working life of wind-driven generator;
2, because tubular wind-collection cover mouthful is horn-like windward, the wind being blown out by fan blade can be focused in tubular wind-collection cover, afterbody by tubulose connecting rod blows out, form negative pressure at the one or both sides of rudder face, make rudder just can swing rapidly as for the mobile wind direction of wind consistent at gentle breeze state, so just can effectively improve wind and act on the power on fan blade, also can promote fan blade at gentle breeze state and rotate.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the A-A sectional view of the utility model accompanying drawing 1.
Embodiment
As shown in Figure 1, 2, there is tubular wind-collection cover 2 at wind-driven generator 3 overcoats, wind-driven generator is fixedly mounted in tubular wind-collection cover, the right-hand member of wind-driven generator namely front end is provided with fan blade 1, at tubular wind-collection cover left end, tubulose connecting rod 4 is installed, tubulose connecting rod is connected with the exhaust outlet of opening on tubular wind-collection cover right side, has the elongated slot along its axis at tubulose connecting rod left end, rudder 6 is inserted in elongated slot, and the upper end of column 8 is connected with tubular wind-collection cover.
The fan blade of installing on wind-driven generator rotates under the effect of wind-force, drives wind-power electricity generation rotary electrification.Because the mouth windward of tubular wind-collection cover is horn-like, just can be by wind by tubular wind-collection cover, in tubulose connecting rod, blow out along tubulose connecting rod left end exhaust outlet 5, because the cross section of tubulose connecting rod is less than the cross section of tubular wind-collection cover, be greater than the natural wind speed of natural direction rudder both sides by the wind speed blowing out along tubulose connecting rod left end exhaust outlet, will form in rudder both sides negative pressure, the seat 7 that is rotatably connected that wind-driven generator entirety is connected with tubular wind-collection cover along column upper end is rotated, rudder is adjusted to rapidly consistent with the direction of wind, so just can make fan blade windward side at utmost accept the effect of wind-force, just can make wind turbine power generation at gentle breeze state.
For further improving the sensitivity of wind-driven generator at gentle breeze state, can be closed state by the end face of the tubulose connecting rod of rudder one side, so only there is exhaust outlet in a side of rudder, can form negative pressure in rudder one side.
Technological scheme of the present invention is particularly suitable for the use of small-sized wind power generator.
Claims (3)
1. the rotatable rudder of wind-driven generator, comprise and be arranged on the fan blade of wind-driven generator front end and be arranged on the rudder that wind-driven generator rear end is fixedly linked by connecting rod, and the column of support wind-driven generator, it is characterized in that there is tubular wind-collection cover (2) at above-mentioned wind-driven generator (3) overcoat, tubular wind-collection cover front end windward mouth is relative with fan blade (1), rear end has exhaust outlet, one end of tubulose connecting rod (4) is connected with exhaust outlet, the other end has the elongated slot along its axis, rudder (6) is inserted in elongated slot, column (8) upper end is connected with tubular wind-collection cover.
