[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Combination Figs. 1 to 3 As shown, a power supply device for a tower bolt robot includes a miniature sliding contact line 2 installed on the inner wall of the tower flange 1 and a power taking device 3. The miniature sliding contact line 2 includes a flexible substrate 21, which is insulated and has an adhesive backing for attaching to the inner wall of the tower flange 1. Two conductive metal strips 22 for transmitting current are laid on the flexible substrate 21. The power supply device 3 includes a magnetic chuck 31, an elastic conductive contact 32, a bullseye wheel 33, and a nylon skeleton 34. The magnetic chuck 31 is driven by a motor to rotate along the tower flange 1.

[0017] The thickness of the conductive metal strip 22 is adjusted according to the perimeter of the inner surface of the tower flange 1 and the magnitude of the transmitted current to ensure that the temperature rise of the conductive metal strip 22 is within a safe range during operation.

[0018] The miniature sliding contact line 2 also includes an electromagnetic strip 4 that is adsorbed onto the inner surface of the tower flange 1. One side of the electromagnetic strip 4 is adsorbed onto the inner surface of the tower flange 1, and the other side is connected to the flexible substrate 21.

[0019] The width of the elastic conductive contact 32 of the power taking device 3 is not less than 10mm, and it matches the width of the conductive metal strip 22.

[0020] It also includes a dual-band magnetic resonance system, which includes a main operating frequency of 6.78MHz for energy transmission and an auxiliary positioning frequency of 125kHz for attitude detection. Frequency division multiplexing technology is used to avoid signal interference.

[0023] Working principle: In the process of use, the present invention achieves power supply by installing a miniature sliding contact line on the inner wall of the tower flange. The miniature sliding contact line is composed of an insulating flexible substrate with adhesive backing. Two 10mm wide copper sheets are laid on the substrate for transmitting current. It can also be fixed by an adsorption scheme using an electromagnetic strip. The magnetic chuck of the power-collecting device rotates along the flange under the drive of the motor. The bullseye wheel limits the contact between the elastic conductive contact and the copper sheet, thereby obtaining electrical energy. The thickness of the copper sheet is calculated based on the flange perimeter and the transmission current to ensure that the temperature rise is within the allowable range. The power supply unit employs a dual-band magnetic resonance system, with a main operating frequency of 6.78MHz (ISM band) for energy transmission and an auxiliary positioning frequency of 125kHz for real-time attitude detection. Frequency division multiplexing technology is used to avoid signal interference. The three-dimensional positioning and tracking system integrates UWB module (accuracy ±5cm) and gyroscope data, combined with Beamforming algorithm to control the dynamic deflection of the transmitter. The dual-axis servo gimbal achieves horizontal ±180° and pitch ±45° adjustment to ensure accurate energy transmission. An adaptive impedance matching network monitors the receiver's voltage standing wave ratio (VSWR) in real time and uses a PIN diode array to achieve microsecond-level tuning, achieving a transmission efficiency exceeding 85% with a matching error of <1.5%. The energy management system controls power (10-300W) in stages based on RSSI signal strength, and a sleep-wake mechanism with standby power consumption <5W ​​reduces energy consumption. The safety protection system includes a bio-radar liveness detection module and three levels of protection against over-temperature, over-current, and over-voltage to ensure safe operation.
