Abstract
The utility model relates to a prevent wind generating set that collapses, including blade system, cabin system, tower section of thick bamboo system, rotational system, locking system, actuating system and basis. The utility model provides a technical scheme sets up the cabin in tower section of thick bamboo lower extreme through setting up to change into in the cabin of tower bobbin top end to rotate around tower section of thick bamboo central line through the blade ring and accept the wind -force position to the minimum, effectively prevented collapsing of wind generating set.
Description
Technical field
This utility model belongs to energy field, specifically refers to a kind of anti-wind power generating set of collapsing.
Background technology
Along with production of energy is day by day serious to atmospheric pollution, wind-force is increasingly subject to pay attention to as green energy resource, and wind power industry is in fast development, and wind power generating set is producing in a large amount of use in a large number.
The wind power generating set of existing technology, its blade is subject to wind action power, its tower offset this active force, ensure that wind power generating set is not collapsed. Owing to terrestrial climate is abnormal, wind-force is very big sometimes, and the active force that tower is subject to has exceeded the intensity of tower, causes that tower is collapsed, and the especially marine wind power generating set collapsed, is only that the expense of recovery is also high, in order to navigation safety must reclaim again.
Utility model content
This utility model is achieved through the following technical solutions:
A kind of anti-wind power generating set of collapsing, includes blade system, nacelle system, tower system, rotation system, fastening system, drive system and basis.
The blade of described blade system can rotate around the tower centrage of described tower system.
The nacelle position of described nacelle system moves down, and nacelle position is arranged at the lower end of tower, reduces the center of gravity of tower.
The safety plug of described fastening system can disconnect automatically.
The beneficial effects of the utility model are:
The technical scheme of the application turns to the minimum wind-force position that accepts by blade ring around tower centrage, and nacelle position is arranged at tower lower end, reduces tower center of gravity, reaches the purpose preventing wind power generating set from collapsing.

Detailed description of the invention
Describing the technical solution of the utility model by the following examples in detail, below example is merely illustrative of, and is only capable of for explaining and illustrate the technical solution of the utility model, and is not to be construed as the restriction to technical solutions of the utility model.
This utility model provides one anti-wind power generating set of collapsing, as it is shown in figure 1, blade system includes blade 1, blade 2, blade 3, blade 4, wheel hub 5, wheel hub 6, axle 7, axle 8, gear 9, gear 10.Blade 1, blade 2 are fixing with wheel hub 5 to be connected, and wheel hub 5 and axle 7 card load connect, and axle 7 and gear 9 card load connect, and blade 3, blade 4 are fixing with wheel hub 6 to be connected, and wheel hub 6 and axle 8 block dress system, and axle 8 and gear 10 card load connect.
Nacelle system includes groove 11, gear 12, cabin 13, generator shaft 21, load-bearing groove 22. Groove 11 and generator shaft 21 are rotationally connected, and gear 12 and generator shaft 21 card load connect. Load-bearing groove 22 and generator shaft 21 are rotationally connected, and load-bearing groove 22 accepts generator shaft 21 weight. Having vertical-axis generators in cabin 13, cabin 13 can also arrange trunnion axis electromotor, then generator shaft 21 then changes power transmission shaft 21 into. The gear 9 of blade system, gear 10 engage with the gear 12 of nacelle system and are connected.
Tower system includes tower 23, and the cabin 13 of nacelle system is fixing with tower lower end to be connected. Groove 11 is fixedly connected on tower 23 upper end.
Rotation system includes rotational structure 24, and rotational structure is prior art, and the rotation such as revolving restaurant, large-scale radial drill lathe designs. Rotational structure 24 upper end is fixing with the lower end of tower 23 to be connected, and tower 23 can surround tower 23 centrage and rotate. Load-bearing groove 22 is fixedly connected on rotational structure 24 lower end, and rotational structure major part is fixedly installed in basis.
Fastening system includes locking slot 18, safety plug 19, locking member 20, and locking slot 18 is fixing with tower 23 to be connected, and locking member 20 is fixing with basis 25 to be connected; Safety plug 19 is matched in clearance with locking member 20 and locking slot 18, and the intensity of safety plug 19 is pre-set value, and external force exceedes setting value, and locking pin disconnects automatically, is similar to electric fuse. Safety plug 19 can lock tower 23, makes tower 23 can not surround tower 23 centrage and rotates.
Drive system includes switch 14, motor 15, gear 16, gear 17, and switch 14 is fixing with basis 25 to be connected, and motor 15 is fixing with basis 25 to be connected, motor 15 and gear 16 clamping, and gear 16 engages with gear 17 and is connected, and gear 17 is fixed with tower 23 and is connected.
When wind-force is excessive, safety plug 19 disconnects automatically, and Wind power propelling blade 1, blade 2, blade 3, blade 4 turn to around the centrage of tower 23 and minimum accept wind-force position, effectively prevent collapsing of wind power generating set.
When wind-force is normal, starting switch 14, motor 15 drives gear 16 to rotate, gear 16 drives gear 17 to rotate, gear 17 drives tower 23 to rotate, and tower 23 arrives the normal operation position generated electricity, closing switch 14 with moving vane 1, blade 2, blade 3, blade 4, new spare safety pin 19 is embedded locking slot 18, wind power generating set normal operation.
The cabin of existing wind power generating set is positioned at the top of tower, and the cabin 13 of the anti-wind power generating set collapsed is positioned at the bottom of tower 23, and tower 23 center of gravity reduces, and effectively prevent collapsing of wind power generating set.
