When disassembling wind wheel organization, oil hydraulic pump, transport pipe, connector for oil delivery pipe, and rapid pipe joint forms a hydraulic mechanism together, and make it the conduit with fixed base, perforation and circular groove form fluid path, the depression bar of manually-operable oil hydraulic pump, high pressure oil is made to be injected in the oil circuit of fixed base, high pressure oil passes through conduit, perforation, enter circular groove, along with oil pressure increases, the oblique vertebra shape circular hole of fixed base and the main shaft of generator are thrown off mutually gradually along its vertebra degree, and then fixed base and main shaft are thrown off, complete spindle taper cooperation to disassemble, wind wheel organization entirety is removed, simple to operate, efficiency is high, safe and reliable, eliminate many defects and the problem of prior art existence.
Accompanying drawing explanation
Fig. 1 shows the schematic perspective view of the application example of the hydraulic withdrawal wind wheel organization according to wind-driven generator of the present utility model.
Fig. 2 amplifies the schematic diagram showing the wind rotor blade of wind generator fixed base part shown in Fig. 1 and be connected with the oil hydraulic pump of dismounting wind wheel.
Fig. 3 shows the generalized section according to wind-driven generator hydraulic dismounting wind wheel organization of the present utility model along the A-A line in Fig. 2.
Fig. 4 partly cuts open the schematic perspective view amplifying display wind wheel blade fixed seat structure.
Specific embodiment
The utility model is the wind wheel organization that small-sized wind power generator provides a kind of improvement, as Fig. 1, the wind wheel organization 1 of one wind-driven generator is arranged on the connecting end on front side of generator 2, the rear side of generator 2 connects support 3, the bottom of support 3 is arranged on the top of pylon 5 by swirl gear 4, wind wheel disassembly mechanism designed by the utility model makes wind wheel organization 1 be allowed to use one hydraulic-pressure pump 6 to wind wheel organization 1 inside injection high pressure oil, thus makes wind wheel organization 1 depart from like a cork with the main shaft of generator 2.
As shown in Figures 1 to 4, wind wheel organization 1 is provided with several blade 11, fixes around fixed base 12 equal angles interval.Fixed base 12 is formed in one, comprise disk body part 121 and a projection section 122, and the inside running through disk body 121 and boss 122 in fixed base 12 is provided with the circular hole 123 that cross section is oblique vertebra shape, the oblique vertebra face of this circular hole 123 is connected with the main shaft conus portion (not shown) interference fit of generator 2.
Circular hole 123 madial wall that the fixed base 12 of the wind wheel organization 1 of wind-driven generator of the present utility model is also included near boss 122 medium position offers a circular groove 124, laterally offer the perforation 125 of this circular groove 124 of a connection from boss 122 sidewall, longitudinally offer a conduit 126 be connected with above-mentioned perforation 125 from boss 122 end face.This perforation 125 is exposed at the aperture of boss 122 outer surface with blocking 127 shutoff in addition, so form one from the perforate of boss 122 end face between circular hole 123 inwall and generator shaft outer wall of fixed base 12, via conduit 126, perforation 125, towards the closing oil path of circular groove 124 inside.In addition, also screw section is provided with at the filler opening of this conduit 126, when normally working after wind wheel organization 1 is installed, a nut plug can be coordinated to be closed at the filler opening of this conduit 126, when disassembling this wind wheel organization 1, at the filler opening of this conduit 126, a transport pipe rapid pipe joint 128 can be installed, then the connector for oil delivery pipe 61 of oil hydraulic pump 6 be connected with this rapid pipe joint 128.
