Abstract
The utility model provides a wind generating set with a wheel hub and a cabin air exchange device. The wind generating set comprises the wheel hub and a main shaft which is connected with the wheel hub, and is characterized by also comprising a centrifugal blower, a vent pipe and vent holes on a main shaft flange; the vent holes consist of an air inlet hole and an air outlet hole; the centrifugal blower is arranged on an inner wall, which is connected with the main shaft, in the wheel hub; the air inlet of the centrifugal blower corresponds to the air inlet hole; and the vent pipe is arranged at the air outlet of the centrifugal blower. The centrifugal blower is arranged on a wheel hub wall, which is connected with the main shaft, inside the wheel hub, through the a bolt, so that an air inlet position is opposite to the air inlet hole of the main shaft, the vent pipe is arranged at the air outlet of the blower to blow air into the wheel hub; and remaining holes on the main shaft flange are taken as air outlet holes. The wind generating set is simple, is convenient to operate, and the radiating problem of electrically-controlled equipment in the wheel hub with a sealing requirement is solved.
Description
Technical field
The utility model relates to a kind of wind power generating set, relate in particular to a kind of wind power generating set that has the air exchanging apparatus in wheel hub and cabin, this wind power generating set is particularly useful for the environment that there is seal request at rocky dirt area and sea etc., mainly solves the problem of the air exchange that temperature and humidity causes in the wheel hub.
Background technique
General hydraulic pressure or the electronic pitch-controlled system installed in the wheel hub of feather wind-powered electricity generation unit, for land sand and dust bigger area and the bigger area of marine humidity, be the dustproof or anticorrosion wheel hub that needs sealing wind-powered electricity generation unit, the heat radiation of pitch-controlled system and dehumidifying problem just are difficult to solve like this, and these problems have very big influence to the proper functioning of blower fan.Especially the heat dissipation problem for the control panels such as hydraulic buttery valve, servo-system, controller and communication module of wheel hub inside pitch-controlled system seems even more important, if do not carry out corresponding radiating treatment, will make that the wheel hub inside temperature is too high to cause the control panel work in the axial fan hub undesired, thereby influence the availability of wind-powered electricity generation unit, when serious even can produce security incident.
Summary of the invention
Goal of the invention: the utility model provides a kind of wind power generating set that has wheel hub and cabin atmosphere switch, its objective is the problem that can't dispel the heat and dehumidify that solution wind power generating set in the past adopts the sealing wheel hub to prevent dust or brought when anticorrosion.
Technological scheme: the utility model is achieved through the following technical solutions:
A kind of wind power generating set that has wheel hub and cabin atmosphere switch comprises wheel hub and the main shaft that is connected with wheel hub, it is characterized in that: described device also comprises centrifugal blower, ventilation duct and is arranged on vent hole on the spindle flange; Described vent hole is divided into intake opening and exhaust vent; Described centrifugal blower is installed on the inwall that wheel hub is interior with main shaft is connected, and the intake grill of centrifugal blower is corresponding with intake opening; Ventilation duct is arranged on the exhaust outlet of centrifugal blower.
The quantity of described vent hole is a plurality of, and a plurality of vent holes are evenly distributed on the spindle flange.
Advantage and effect: the utility model provides a kind of wind power generating set that has wheel hub and cabin atmosphere switch, comprise wheel hub and the main shaft that is connected with wheel hub, it is characterized in that: described device also comprises centrifugal blower, ventilation duct and is arranged on vent hole on the spindle flange; Described vent hole is divided into intake opening and exhaust vent; Described centrifugal blower is installed on the inwall that wheel hub is interior with main shaft is connected, and the intake grill of centrifugal blower is relative with intake opening corresponding, and ventilation duct 1 is arranged on the exhaust outlet of centrifugal blower.
Centrifugal blower is installed on the wheel hub wall that wheel hub is inner with main shaft is connected by bolt, guarantee that the air intake place is relative with the intake opening of main shaft, ventilation duct is installed in the exhaust outlet of blower, is used for drying in wheel hub, and all the other holes on the spindle flange are as exhaust vent.The utility model is simple, easy to operate, has solved the heat dissipation problem of control panel in the wheel hub that seal request is arranged.
Description of drawings:
Fig. 1 is structure of the present utility model and scheme of installation;
Fig. 2 is a work schematic representation of the present utility model;
Embodiment:Below in conjunction with accompanying drawing the utility model is further described:
As illustrated in fig. 1 and 2, the utility model provides a kind of wind power generating set that has wheel hub and cabin atmosphere switch, comprise wheel hub and the main shaft that is connected with wheel hub, main shaft is connected with wheel hub by flange, and described device also comprises centrifugal blower 2, ventilation duct 1 and is arranged on vent hole 3 on the spindle flange; Described vent hole 3 is divided into intake opening and exhaust vent; Described centrifugal blower 2 is installed on the inwall that wheel hub is interior with main shaft is connected, the intake grill of centrifugal blower 2 is relative with intake opening corresponding, the exhaust outlet that ventilation duct 1 is arranged on centrifugal blower 2 is used for drying in wheel hub, and all the other vent holes on the spindle flange are as exhaust vent.Use centrifugal blower, carry out air exchange by 3 pairs of cabins of the vent hole on the spindle flange and wheel hub.Centrifugal blower intake grill and the relative air intake that is used for of intake opening on the spindle flange, the exhaust outlet of centrifugal blower ventilates in wheel hub by ventilation duct.
The spread pattern of vent hole can change according to the unit concrete condition.The quantity of described vent hole 3 is a plurality of, and a plurality of vent holes 3 are evenly distributed on the spindle flange.Its quantity is decided according to main axe intensity, just when guaranteeing spindle flange intensity a plurality of vent holes 3 can be set,
As shown in Figure 2, centrifugal blower 2 is drawn into the air in the cabin in the wheel hub by intake grill, and the air draft by ventilation duct makes air circulation in wheel hub, hot air in the wheel hub is discharged it by the exhaust vent on the spindle flange.The arrow that alphabetical A among Fig. 2 represents is the air intake direction, and the arrow that letter b is represented is an air-out direction; The arrow that letter C is represented is an air exchange.
This model utility has well solved the not smooth problem of air exchange that temperature and humidity causes in the wheel hub, is beneficial to and applies.
