Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The invention discloses an intelligent rotary deicing robot based on a multi-rotor aircraft, which can be used for deicing cables, and comprises a multi-rotor aircraft 1 and a deicing manipulator 2, wherein the deicing manipulator 2 is positioned under the multi-rotor aircraft 1 and is connected through a fixing rod 9, as shown in figure 1.
As shown in fig. 2, the multi-rotor aircraft 1 includes a frame 4, a control module 7, a GPS module 8 and rotors are disposed on the frame 4, each rotor is connected to a brushless motor 5, and each brushless motor 5 is connected to a motor speed regulator 6.

Wherein, a vertical bottom plate 10 is arranged below the fixed rod 9, one side of the bottom plate 10 is provided with a solenoid 12, the solenoid 12 is hollow, and two ends of the solenoid 12 are provided with a plurality of fixed pulleys 11; the rotary rod 13 is arc-shaped, the central line thereof is arc line 21, the center of the arc line 21 is O, as shown in fig. 7 and 10, the permanent magnet 14 is embedded in a certain section in the middle of the rotary rod 13 to form a complete and smooth rotary rod 13, and the rotary rod 13 can be just inserted into the solenoid 12, and the rotary rod 13 can freely perform rotary motion under the positioning of the fixed pulley 11.
The two ends of the swiveling lever 13 are further provided with a left limit bolt 15 and a right limit bolt 16 for limiting the position of the swiveling lever 13 during swiveling motion so as to avoid swiveling. A first laser 17 is arranged on one side of the left limit bolt 15, a second laser 18 is arranged on one side of the right limit bolt 16, laser light rays emitted by the first laser 17 and the second laser 18 pass through a circle center O of an arc line 21 where the rotating rod 13 is located, an included angle formed by the laser light rays is theta, the range is 150 degrees and more than theta and less than 210 degrees, in the embodiment, the theta is 180 degrees, namely the first laser 17 and the second laser 18 are in a correlation state, and when the rotating rod 13 rotates, laser light emitted by the first laser 17 and the second laser 18 always irradiates the circle center O of the semicircle of the rotating rod 13, as shown in fig. 7-10.
The solenoid 12 is used to generate a magnetic field, and the driving current applied thereto is an alternating current, which enables the solenoid 12 to generate a magnetic field that varies periodically in magnitude and direction. The magnetic field acts on the magnetic field of the permanent magnet 14, and due to repulsion of like poles and attraction of unlike poles, the magnetic field generated by the solenoid 12 changes back and forth, so that the force applied to the cyclic rod 13 changes back and forth, and finally the cyclic rod 13 performs periodic cyclic motion around the center O. The rotary motion can make the laser spots emitted by the first laser 17 and the second laser 18 move on the cable 3, so that multi-directional and multi-angle deicing is realized.
As shown in fig. 3 to 5, the back of the bottom plate 10 is further provided with a first image sensor 19 and a second image sensor 20, the viewing angle direction of the first image sensor 19 is vertically downward, the viewing angle direction of the second image sensor 20 is horizontally leftward and respectively points to the cable 3, the viewing angle directions of the first image sensor 19 and the second image sensor 20 intersect at an O 'point, the O' point is also the center point position of the cable 3, a connecting line between the O 'point and the O point is perpendicular to a plane where the arc line 21 is located, and the cable 3 is located on the connecting line between the O' point and the O point, as shown in fig. 5.
If the cable 3 is imaged at the central positions of the first image sensor 19 and the second image sensor 20 respectively, it indicates that the cable 3 is right at the center O of the swing arm 13 at this time, the laser spots of the first laser 17 and the second laser 18 are right directed to the cable 3 at this time, and the first laser 17 and the second laser 18 can be turned on to start deicing at this time; if the cable 3 is not imaged in the central position of the first image sensor 19 and the second image sensor 20, it is indicated that the cable 3 is not at point O, and the position of the multi-rotor aircraft should be adjusted: when the cable 3 is not imaged in the center of the first image sensor 19, the horizontal position of the multi-rotor aircraft should be adjusted so that the cable 3 is located in the center of the first image sensor 19; when the cable 3 is not imaged in the center of the second image sensor 20, the vertical position of the multi-rotor aircraft should be adjusted so that the cable 3 is centered in the second image sensor 20. The cable 3 is imaged at the central O' point of the first image sensor 19 and the second image sensor 20, respectively, which indicates that the cable 3 is at the O point, and at this time, the deicing condition is satisfied, and the first laser 17 and the second laser 18 can be turned on for deicing. During the deicing process, the multi-rotor aircraft will adjust the position of the multi-rotor aircraft in real time through the imaging conditions of the first image sensor 19 and the second image sensor 20 to ensure that the cable 3 is in the O point position in real time.
As shown in fig. 11 and 12, the deicing method of the present invention is as follows:
after the system is powered on, initialization is carried out firstly, then the multi-rotor aircraft searches for the cable 3 through the first image sensor 19 and the second image sensor 20, and after the cable 3 is found, the current position of the cable 3 is determined through the imaging conditions of the first image sensor 19 and the second image sensor 20. When the cables 3 are both imaged in the center positions of the first image sensor 19 and the second image sensor 20, it indicates that the cables 3 are currently in the O', O point position, i.e. the cables 3 are in the center position. At this point, first laser 17 and second laser 18 will be turned on, solenoid 12 is energized, cyclic rod 13 will begin to cycle, the multi-rotor aircraft advances, and laser de-icing begins.
In the laser deicing process, the multi-rotor aircraft stores the current GPS data in a storage module in real time on one hand, and on the other hand, the multi-rotor aircraft adjusts the position of the multi-rotor aircraft in real time, so that the cable 3 is positioned in the center of the first image sensor 19 and the second image sensor 20 until the deicing is finished, the first laser 17 and the second laser 18 are turned off, the rotary rod 13 returns, the solenoid 12 is powered off, and the multi-rotor aircraft returns to land.
