Abstract
A wind generating set without unmooring operation belongs to the technical field of wind generating sets, and comprises a blade, a hub, a magneto generator, a cabin and a tower, wherein the blade is connected with the hub; the hub is connected with the rotor of the magneto generator; the stator of the magneto generator is connected with the cabin rack of the cabin; the cabin rack is connected with a yawing bearing inner ring in the cabin; an yawing bearing outer ring is connected with the tower; and a conductive slip ring component, through which a cable penetrates, is arranged between the cabin rack and an upper flange of the tower. As the operation of hanging a part of the cable in a cable twisting device and the abrasion of the cable when the cable sways with the tower are avoided during the operation of the wind generating set, the requirement on the cable is reduced, that is, a twist-resistant cable can be replaced by a common cable. Therefore, unmooring is not required; time spent in unmooring caused by the over-twisting of the cable is saved; the generated electrical energy is increased; functions corresponding to unmooring and related components of the conventional hydraulic station are eliminated; the control part corresponding to unmooring during a control process is also eliminated; and the failure rate of a blower is reduced.
Description
Technical field
The utility model belongs to the generator set technical field, particularly relates to a kind of wind power generating set that need not cable-releasing equipment.
Background technique
Wind power generating set is when the wind direction of reply change at random at present, and the strategy of employing is the driftage and the system of untying the mooring rope.This system is when the every deflection several angle of wind direction, and the same angle of blower fan corresponding deflection is to guarantee that wind wheel is over against wind direction.Simultaneously because the electric energy that sends from generator need be transported to the bottom surface from the cabin by cable, like this when blower fan accumulative total rotation on certain direction reaches several angle, be wound and twist into two parts for fear of the transmission of electricity cable, so need the mechanism of untying the mooring rope when blower fan rotates to limit position, to rotate to an angle round about continuously, with releases cable.This driftage is untied the mooring rope, and to be the cable that is suspended on the tower tube can twine several angle in order to go off course for the defective of mechanism, so be free relaxed state, when pylon rocks during fan operation, unavoidable take place and metal parts friction on every side the insulation rubber wearing and tearing occur and causes getting an electric shock or the accident of fire.Blower fan needs the process that a shutdown is untied the mooring rope and started when untying the mooring rope simultaneously, and this has also influenced generated energy.
Summary of the invention
The problem that the utility model solves is: provide a kind of no matter how wind direction changes the wind power generating set that need not cable-releasing equipment that all can turn round continuously.
To achieve these goals, the technical solution of the utility model is:
The utility model comprises blade, wheel hub, permanent magnet generator, cabin and tower tube, described blade is connected with wheel hub, wheel hub is connected with rotor of permanent-magnetic power generator, the cabin frame in permanent magnet generator machine stator and cabin is connected, the cabin frame is connected with driftage bearing inner race in the cabin, the yaw axis bearing outer-ring is connected with the tower tube, it is characterized in that: also be provided with the conducting slip ring parts by cable between described cabin frame and tower tube upper flange.
Described conducting slip ring parts comprise fixed base and conducting slip ring, described fixed base is installed on the interior circle of frame bottom, cabin, the outer shroud of conducting slip ring is fixed on the fixed base, the interior ring of slip ring is fixed by the fixing rod that is fixed on the tower tube inwall, and conducting slip ring, fixed base and tower tube three are coaxial; The fixing simultaneously cable that comes out from the slip ring two ends of slip ring fixed base and tower tube fixing rod.The described fixing rod that is fixed in tower tube inwall is a band steel, is welded on the tower tube inwall.
Blade described in the utility model and wheel hub adopt Stall Type blade and fixed pitch system.Perhaps, described blade and wheel hub adopt non-Stall Type blade and pitch-controlled system to form.
The beneficial effects of the utility model are:
The situation that the utility model is in operation and has avoided turning round a part of cable of required suspension in the cable device and occurred wearing and tearing when rocking with the tower tube has also reduced the requirement to cable simultaneously, can replace antitorque cable with common cable.Because need not to untie the mooring rope, so also avoided twining when excessive at cable, untie the mooring rope the needed time, thereby improved generated energy.Because there is not cable-releasing equipment, so omit the neutralization of traditional hydraulic station untie the mooring rope corresponding function and associated components; Simultaneously, also omitted in the control program and the corresponding control section that unties the mooring rope; Therefore whole blower fan controlling method and and the complexity of the hydraulic system of the cooperating that unties the mooring rope all decrease, this has also reduced the fan trouble rate to a certain extent.
