Referring to fig. 2, four crushing rods 2 with different lengths are symmetrically fixed below the left end of the sailboard 14 through steel clamps 3, and a pair of toothed cutters 15 is fixed below the right end of the sailboard through screws 16. Four fan motors 4 are symmetrically arranged at the four wings of the windsurfing board 14, and a fan 22 is arranged at the shaft end of each fan motor 4. The battery 5 is fixed on the left side of the middle of the windsurfing board 14, and the motor 13 is fixed on the right side of the middle of the windsurfing board 14. The front end gear 12 is connected to the shaft end of the motor 13 through the coupling 18, the front end gear 12 and the gear shaft 11 are in the same body, the rear end gear 8 is sleeved on the middle portion of the gear shaft 11 to the left through a flat key 8a, the inner ring of the bearing 6 is sleeved on the left end of the gear shaft 11, the outer ring is sleeved in the bearing seat 21, and the bottom of the bearing seat 21 is fixed on the sailboard 14 through a screw assembly 28. Referring to fig. 4, four square holes 23 are formed in the middle of the windsurfing board 14, and guide pins 27 are fixed in the two square holes 23 at the front end of the windsurfing board 14. The outer rings of the two gear rings 19 are respectively meshed with the front end gear 12 and the rear end gear 8, and the front ends of the two gear rings extend into two square holes 23 on the front side of the windsurfing board 14. The middle part of the gear ring 19 is provided with a guide groove 30 along the axial direction, and the guide groove 30 is clamped on the guide pin 27 and can freely slide.
As shown in fig. 1, 2 and 4, a base 10 is fixed at the center of the sailboard 14, a shaft hole 29 is formed in the middle of the base 10, the gear shaft 11 passes through the shaft hole 29, and a blade 9 is fixedly mounted on the upper portion of the base 10 through a bolt assembly 26. An inclined base 20 is fixed at the front edge and the rear edge of the middle part of the sailboard 14, and a blade 9 is fixed on each inclined base 20 through a bolt assembly 26. The three blades 9 are mutually at an angle of 120 degrees.
As shown in fig. 1, 3 and 4, four saddle plates 17 are fixed under the sailboard 14 along the axis, and the saddle plates 17 and the gear ring 19 are buckled and encircled on the cable 1. As shown in fig. 2, 3 and 4, 7 solar thin film cells 25 are adhered to the upper surface of the sailboard 14, 5 solar thin film cells 25 are adhered to the lower surface of the sailboard, and 2 solar thin film cells 25 are adhered to the outer surfaces of the three blades 9. The storage battery 5 supplies power to the fan motor 4 and the motor 13, and the solar thin film battery 25 charges the storage battery 5. The motor 13, the gear shaft 11, the gear ring 19 and the saddle plate 17 are matched to enable the sailboard to be encircled on the cable 1, and the three blades 9 enable the sailboard 14 to horizontally move along the cable 1 while rotating around the cable by means of wind power. The four fans 22 provide on the one hand the power for lifting the apparatus and on the other hand the rotational power for the windless blades 14 instead of the blades 9 or in low wind weather.
The sailboard 14 and the blades 9 are made of carbon fiber materials, the base 10, the inclined base 20, the saddle plate 17, the gear ring 19, the gear shaft 11, the front end gear 12, the rear end gear 8 and the coupler 18 are made of aluminum alloy materials, and the ice crushing rod 2, the steel clip 2 and the toothed cutter are made of stainless steel materials.
The use of the invention is divided into three steps: ascending-operating the remote control device, starting the fan motor 4, and conveying the four-wing three-paddle wind-solar complementary power transmission line deicing equipment according to the present invention to the upper part of the cable 1 by means of the thrust of the fan 22. After the centre line of the sail panel 14 is collinear with the cable 1, the speed of the fan 22 is reduced so that the saddle plate 17 rides exactly on the cable 1. The motor 13 is started to rotate the ring gear 19 clockwise to engage the saddle plate 17, so that the device is securely embraced on the cable 1.
Deicing, the cable is mostly positioned at the height of hundred meters, the air flow rate is high, and under the action of wind power, the three blades 9 rotate anticlockwise, so that the sailboard 14 is driven to rotate anticlockwise around the cable 1 and move horizontally along the cable 1. If no wind exists or the wind speed is lower than 4 levels, the fans are started, so that the two fans 22 at the front end of the windsurfing board 14 generate downward thrust, the two fans 22 at the rear end generate upward thrust, and the windsurfing board 14 is urged to rotate anticlockwise around the cable 1. Four ice crushing bars 2 fixed to the left end of the windsurfing board 14 rotate together with the windsurfing board 14 to knock the ice coating around the cable 1, thereby dropping most of the ice coating. A pair of toothed knives 15 fixed to the right end of the windsurfing board 14 rotate with the windsurfing board 14 to scrape the remaining ice coating on the cable 1 and thereby detach all the ice coating from the cable 1. The solar film battery 25 adhered on the surfaces of the sailboard 14 and the blades 9 can absorb sunlight to continuously charge the storage battery 5, thereby ensuring the continuous work of the fan 22. If the wind speed is above level 4, the fan 22 need not be turned on to provide rotational power to the windsurfing board 14.
Descending-after de-icing is complete, the remote control is operated to start the fan motor 4 and reverse the motor 13 to move the gear ring 19 counterclockwise away from the saddle plate 17 and to fly the equipment off the cable 1 by the thrust of the four fans 22. The speed of the fan 22 is adjusted to fly the device back to the ground.
After the deicing operation is finished, the storage battery 5 does not need to be disassembled. In 24 hours before each operation, the equipment is placed under the sunshine for insolation, and the storage battery 5 is fully charged. And in rainy days, the storage battery 5 is charged by the 24V direct current power supply.
