[0037] Working principle: first, the staff will drag the test power body 1 to the wind turbine generator set and related system to be tested, then pull out the power line and place it on the sliding seat 38 on the top of the bottom platform 37, and naturally drop the power line downward, so that the top of the power line abuts against the bottom of the ceramic bending rod 35, temporarily fixing it, the rubber anti-skid block 39 has the effect of preventing slipping, at this time, the part of the ceramic bending rod 35 bent downward by 50-60 degrees exerts force downward through the elastic force of the volute spring 36, temporarily clamping the power plug;

[0038] Subsequently, the staff through a hand to turn the crank 23, crank 23 rotating pulley set 22, through the pulley set 22 in the large pulley, drive ten times smaller pulley, because the number of turns of the ten times smaller pulley will be enlarged, so will accelerate the drive impeller 21 high speed rotation, impeller 21 rotation produces a large amount of airflow, from the air inlet to suck in the air, through the high speed rotating leaves to push the gas movement, start blowing air, and from the duct 13 blowing pipe 12, blowing pipe 12 end opening through the side air inlet 100 to the socket set 10 inside the plug blowing high speed gas, through the high speed gas will be inserted into the socket set 10 inside the plug electrode on the dust or long time not used to produce the cobweb or mosquito corpse blowing, keep the power cord and the socket set 10 in the electrode contact when the cleanliness, while the side air inlet 100 open in the socket set 10 inside the plug root, does not affect the insertion of the power plug;

[0039] At the same time, the crank 23 in rotating impeller 21, will also drive the rotating rod 25 rotation through the pulley set 24, rotating rod 25 drive gear 26 rotation, the gear 26 clockwise rotation, drive the rack 32 connected with the mesh to push up, and drive the lifting plate 30 in the front end of the protection shell 11 slide up, drive the power plug on the top sliding seat 38 of the bottom platform 37 to lift up, without manual lifting power cord, when lifting to the top, the staff stop rotating the crank 23, at this time through a hand holding the crank 23, a hand directly one by one to rotate the power plug, a certain angle, so that it is perpendicular to the socket set 10 in the sliding seat 38 of the plug hole, then slowly push forward the power plug, through the sliding seat 38 in the bottom platform 37 sliding connection, while the rubber anti-skid block 39 increases the friction between the sliding seat 38 and the bottom of the power plug, at this time the power plug is protected by the ceramic bending rod 35 and limited by the limiting rod 33, slowly and accurately inserted into the socket set 10 of the plug hole, without skewing;

[0040] Subsequently, the crank 23 is released with one hand, the lifting plate 30 is connected with the protection shell 11 by damping, because the gravity of the power plug has been transferred to the socket set 10 at this time, the lifting plate 30 will stop at the front end of the protection shell 11, while the bottom platform 37, the ceramic bending rod 35 and the top protrusion of the sliding seat 38, including the limiting rod 33, can also protect the power plug which has been inserted;

[0041] The elastic force of the volute spring 36 to the ceramic bending rod 35 will keep the ceramic bending rod 35 at the position of the back shell of the power plug, cooperating with the limiting rod 33, so that the power plug will not be bent at a large angle, reducing the risk of line damage or short circuit of the power cord, and finally starting the test power supply body 1 to start testing.

[0042] When the test power supply body 1 tests the wind turbine generator and the related system, the staff first pulls out all the power supply plugs slowly in turn, drives the sliding seat 38 to move backward on the bottom platform 37, holds the crank 23 with one hand and reverses the rotation of the crank 23, drives the lifting plate 30 of the plug-pull assembly 3 to slowly lower the power supply plug, and finally lowers to the bottom, then pulls out the power supply plug from the clamping of the sliding seat 38 and the ceramic bent rod 35, completes the pulling out work of the power supply plug, and does not damage the socket set 10 and the power supply plug, finally collects the power supply plug to the original place, and completes the test.
