Abstract
The utility model discloses a wind driven generator tower structure which is a three-section hydraulic structure consisting of first to third sections, wherein the telescopic length of the first section and the second section of the tower can be changed according to needs, and the length of the third section is unchanged. A control cabinet capable of adjusting the height of the tower is arranged inside the third section, and when wind speed at an impeller hub is larger than or lower than a certain value of the rated wind speed, the control cabinet can adjust the height of the tower according to the intensity of the wind speed. By adoption of the structure, the energy capture of a wind wheel can be reduced, the rotating speed of an impeller can be maintained within the rated value, simultaneously, the bearing load of vanes and the impact on the whole wind driven generator can be reduced, thus ensuring the wind driven generator not to be damaged, and simultaneously reducing the manufacturing cost of the vanes.
Description
Technical field
The utility model relates to technical field of wind power generating equipment, relates in particular to a kind of pylon structure of wind-driven generator.
Background technique
Along with the mankind to the requirement of ecotope with to the needs of the energy, the exploitation exploitation of wind energy comes into one's own day by day, wind-power electricity generation will become a kind of renewable and clean energy resource of 21 century large-scale development.Wind energy is a kind of as renewable energy sources, and is quite abundant the reserves of China.Along with improve constantly the continuous maturation with small-size wind power-generating technology of people to wind-power electricity generation understanding, its application also more and more widely.
Wind-driven generator is to utilize the wind energy of occurring in nature to make it to be converted into the electricity generating device of electric energy.Wind power generating set is operated in certain wind speed range, under a lot of situations, no matter require the wind energy conversion system wind speed how to change, always rotating speed keeps constant or is no more than a certain limit value.Wind power generating set is after surpassing rated wind speed, because the restriction of mechanical strength and physical properties such as generator, power electronics capacity, must reduce the energy capture of wind wheel, reduce blade and bear the impact that load and whole wind machine are received, power output is remained near the rating value, guarantee that wind energy conversion system does not suffer damage.
Pylon is the supporting structure of wind-driven generator, is the indispensable part of wind power generating set.Stressing conditions when pylon is all worked according to wind power generating set manufactures and designs, and has very high rated wind velocity.Wind shear is a kind of of meteor, and it has reacted the situation that wind speed changes along with variable height.Usually adopt following formula to calculate wind shear:
In the formula, α represents wind shear exponent; z
1Represent to appoint and get the height (as 25m) of a bit; z
2Represent to appoint and get the height (as 40m) of a bit; v
1Be illustrated in height z
1The wind speed at place; v
2Be illustrated in height z
2The wind speed at place.For same typhoon power generator, under the identical situation of other condition, the high more wind speed that obtains of the height of pylon is big more.
Summary of the invention
In order to overcome above-mentioned prior art shortcoming, the utility model proposes the novel pylon structure of a kind of wind-driven generator, this novel structure, production technology are simple.
The technological scheme that its technical problem that solves the utility model adopts is: use can be regulated the pylon structure of height open side type automatically.Pylon is the hydraulic structure of 3 stops, comprises first section, second section and the 3rd section, and wherein second section of first section of pylon, pylon are connected for the 3rd section successively with pylon; First section the other end of pylon is connected with the cabin; The 3rd section the other end of pylon is connected with column foot; End in the cabin is equipped with blade; Be provided with control cabinet at pylon the 3rd intersegmental part, this control cabinet comprises processor, final controlling element etc.First and second section of pylon can change collapsing length as required, and the 3rd segment length is constant.At the 3rd intersegmental part the control cabinet of can regulate pylon height is housed, when impeller hub place wind speed surpassed or is lower than rated wind speed certain value (can be set by control cabinet), control cabinet can be according to the height of wind speed size adjustment pylon.
Adopt technical solutions of the utility model can reduce the energy capture of wind wheel, wind speed round is remained on below the rating value.Reduce blade simultaneously and bear load and the whole wind machine impact of receiving, guarantee that wind energy conversion system does not suffer damage, the while has also been reduced the manufacture cost of blade.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Label among the figure is represented respectively: 1, control cabinet; 2, column foot; 3, the 3rd section 4 of pylon, second section of pylon; 5, pylon is first section; 6, cabin; 7, impeller; 8, wheel hub is described in further detail content of the present utility model below in conjunction with accompanying drawing.
Embodiment
With reference to shown in Figure 1, pylon is formed by three sections, comprises the 3rd section 3 of first section 5 of pylon, second section 4 of pylon and pylon, and wherein second section 4 of first section 5 of pylon, pylon are connected for the 3rd section 3 successively with pylon; First section 5 the other end of pylon is connected with cabin 6; The 3rd section 3 the other ends of pylon are connected with column foot 3; Be provided with control cabinet 1 in the 3rd section 3 inside of pylon, this control cabinet 1 comprises processor, final controlling element etc.
When wheel hub 8 place's wind speed of impeller 7 during greater than the rated wind speed limit value, control cabinet 1 will start processor inside, calculate the height that pylon need reduce, shorten the length of first section 5 of pylon then by final controlling element, if pylon can not shorten for first section 5 again, then shorten the length of second section 4 of pylon by final controlling element.When wheel hub 8 place's wind speed of impeller 7 during less than the rated wind speed limit value, control cabinet 1 will start processor inside, calculate the height that pylon need raise, then by the length of second section 4 of final controlling element elongation pylon, if pylon can not extend for second section 4 again, then by the length of first section 5 of final controlling element elongation pylon.When wheel hub 8 place's wind speed of impeller 7 return to rated wind speed, pylon will recover its operational height.
