[0029] The driving assembly includes an outer ring friction sleeve 117 fixed at the center position of the lower surface of the base plate 101, and an outer ring gear disc 102 is rotatably installed on the inner side of the outer ring friction sleeve 117. The outer ring gear disc 102 is fixedly and synchronously driven with the bottom displacement frame 109. A central gear 104 is arranged at the inner center position of the outer ring gear disc 102 through three planetary gears 103 meshing and transmission. The three planetary gears 103 are rotatably installed on a planetary gear support disc 105, and the planetary gear support disc 105 is rotatably installed inside the outer ring friction sleeve 117. A plurality of slide rails 106 are radially provided on the planetary gear support plate 105, and a friction magnetic column 107 is slidably provided on each slide rail 106. The friction magnetic column 107 is frictionally matched with the inner wall of the outer ring friction sleeve 117. An electromagnet 118 is provided on the outer side of all the friction magnetic columns 107, and the electromagnet 118 is sleeved on the outer ring friction sleeve 117. A central stop block 108 that magnetically matches with the friction magnetic columns 107 is fixed at the center of the planetary gear support plate 105. A first permanent magnet that magnetically matches with the central stop block 108 and a second permanent magnet that magnetically matches with the electromagnet 118 are embedded at both ends of the friction magnetic column 107, wherein the volume of the first permanent magnet is smaller than the magnetic force of the second permanent magnet.

[0030] The lower surface of the base plate 101 is suspended on the driving cone chamber 131 through a plurality of connecting support air guide plates 140. The bottom end of the driving cone chamber 131 is provided with an air inlet, and a gas turbine 132 is rotatably arranged in the air inlet; the outer side of the connecting support air guide plate 140 is provided with a passive impeller 124, which is fixed on a passive impeller support plate 123, which is rotatably matched with the base plate 101, and the passive impeller support plate 123 is also fixedly matched with the bottom displacement frame 109. The driving cone chamber 131 is fixed to the end of the telescopic rod of the multi-stage telescopic rod 135, and the outermost telescopic cylinder of the multi-stage telescopic rod 135 is fixed on the multi-stage telescopic rod bracket 136, which is rotatably mounted on the swing insulation support frame 137, which is fixed on the auxiliary cart 138, and the auxiliary cart 138 is also fixed with a supporting top plate 139 for supporting the driving cone chamber 131.

[0031] The working principle of a multi-group power generation vehicle automatic grid-connected control system disclosed in the present invention is as follows: the auxiliary cart 138 is driven to the bottom of the cable, wherein the swing insulating support frame 137 is insulated. Then the power generation vehicle is driven to the auxiliary cart 138, and then the power transmission docking is performed, so that the output end of the power generation vehicle is conductively connected with the conductive contact strip 129 through a wire (a switch with an arc extinguishing function needs to be provided in the middle). By swinging the multi-stage telescopic rod 135 to a vertical state (a steering gear is provided at the connection between the multi-stage telescopic rod bracket 136 and the swing insulating support frame 137, which is used to drive the swing of the multi-stage telescopic rod 135), and then controlling the multi-stage telescopic rod 135 to extend, the multi-stage telescopic rod 135 drives the driving cone chamber 131 and all the components on the driving cone chamber 131 to move upward, so that the conductive contact strip 129 contacts the corresponding cable, thereby forming a conductive state. Prior to this, the distance between different conductive contact strips 129 needs to be adjusted according to the corresponding cable spacing, and the position of the conductive contact strip 129 on the adjustment beam 128 can be adjusted and fixed by rotating the nut 133. However, it is unlikely that the auxiliary trolley 138 will travel right under the cable, so it is necessary to adjust the position of the conductive contact strip 129 and then align the conductive contact strip 129 with the cable. Specifically, the horizontal displacement of the conductive contact strip 129 is controlled by controlling the bottom transmission belt 112 and the top transmission belt 116. The adjustment cylinder 126 is controlled, and the telescopic rod of the adjustment cylinder 126 drives the adjustment arm 127 to swing. The adjustment arm 127 drives the overhead frame 125 to swing. The overhead frame 125 drives all the conductive contact strips 129 on the adjustment beam 128 to swing. Because the ground may be uneven and the cable will sag under the action of gravity, this will cause the position where the cable contacts the conductive contact strip 129 to not be completely horizontal. Therefore, the horizontal angle of the conductive contact strip 129 needs to be adjusted to ensure that the contact area between the conductive contact strip 129 and the cable surface is maximized. At the same time, the position where the auxiliary trolley 138 stops is likely to have an angle with the length direction of the cable, so the conductive contact strip 129 needs to be rotated so that the conductive contact strip 129 is parallel to the cable. Specifically, the output shaft of the servo motor 120 drives the central gear 104 to rotate, and the electromagnet 118 is started at the same time. The electromagnet 118 magnetic force attracts the friction magnetic column 107 to move toward the inner wall of the outer ring friction sleeve 117, and then squeezes and rubs with the inner wall of the outer ring friction sleeve 117. Since the friction magnetic column 107 is installed on the planetary gear support disk 105, the rotation of the planetary gear support disk 105 can be limited by the friction magnetic column 107. When the planetary gear support disk 105 cannot rotate, the central gear 104 will drive the outer ring toothed disk 102 to rotate through the planetary gear 103, and the outer ring toothed disk 102 drives the bottom displacement frame 109 on the base disk 101 to rotate, thereby driving the conductive contact strip 129 to rotate a corresponding angle.In this way, the electricity generated by the generator truck can be connected to the power grid at any location of the cable section without power, without the need for the generator truck to drive to a designated location, which greatly increases the speed of connecting the generator truck to the power grid.

[0032] Sometimes, due to long-term storage (not frequently used) of the device, the surface of the conductive contact strip 129 and other components on the base plate 101 will retain excess materials such as leaves, so it is necessary to remove the excess materials. At this time, the gas turbine 132 can be started, and the gas turbine 132 blows air into the driving cone chamber 131 to increase the internal pressure of the driving cone chamber 131, and then exhausts air to the outside through the connecting support air guide plate 140. The airflow will drive the passive impeller 124 to rotate, and the passive impeller 124 drives the passive impeller support plate 123 to rotate, and the passive impeller support plate 123 drives the bottom displacement frame 109 to rotate. At this time, the electromagnet 118 is in a non-energized state, so all the friction magnetic columns 107 will contact the center stop block 108 under the action of magnetic force, and then separate from the inner wall of the outer ring friction sleeve 117. At this time, the planetary gear support plate 105 is in a free rotation state. The purpose is to reduce the rotation resistance of the bottom displacement frame 109, and the passive impeller 124 drives the conductive contact strip 129 to rotate at a high speed, so as to throw away the excess material on the conductive contact strip 129. Thus, the cleaning effect is achieved. Since the air flowing out of the passive impeller 124 is along the radial direction of the rotation plane of the passive impeller 124, this will cause the air to flow along the horizontal plane to form a layer of flowing air plane. The air on the upper and lower surfaces of this layer of air plane is relatively static (only the upper surface is considered here), which will cause the pressure on the upper surface of the air plane to be greater than the pressure inside the air plane. Therefore, the external air will flow into the air plane to form a stable airflow, and this part of the airflow will also drive the separation of excess materials.
