[0052] An embodiment of the present invention provides an ultra-high voltage transmission line power testing system based on an unmanned aerial vehicle carrier. For details, see Figure 1 and Figure 2 , Figure 1 The figure shows the overall structure of an ultra-high voltage transmission line power testing system based on an unmanned aerial vehicle carrier in one embodiment of the present invention. Figure 2 The figure shows a schematic diagram of the working state structure of an ultra-ultra-high voltage transmission line electricity testing system based on an unmanned aerial vehicle carrier in one embodiment of the present invention. The overall structure of the ultra-ultra-high voltage transmission line electricity testing system based on an unmanned aerial vehicle carrier includes an unmanned aerial vehicle carrier 10, an electricity testing module 20 and a connection module 30.

[0053] Specifically, the connection module 30 includes a base 301, a drive motor 302, ribs 303 and a flange 304. One end of the flange 304 is connected to the electrical testing module 20, and the other end of the flange 304 is connected to the base 301. The base 301 is provided with a first clamping groove for clamping the drone carrier 10. Each rib 303 is covered on the outer surface of the drone carrier 10. In this embodiment, the base 301 and a plurality of ribs 303 fixedly connected to the base 301 constitute a restraining mechanism.

[0054] Specifically, the connection module 30 also includes a drive motor 302, which is installed on one side of the base 301, and the main shaft of the drive motor 302 is connected to the flange 304. The base 301 is used to install the drone carrier 10, and the ribs 303 are in a cross structure, so that the drone carrier 10 is fixed through the ribs 303. The flange 304 is connected to the power test module 20, and the flange 304 and the power test module 20 are driven to rotate by the drive motor 302 to adjust the angle of the power test module 20 relative to the ultra-high voltage transmission line 100, so as to facilitate the power test of the ultra-high voltage transmission line 100.

[0055] The electrical testing module includes a box 201, a supporting assembly 202, an electrical testing assembly 205, and an electric push rod 203, an electric control box 204 and a telescopic mechanism 206 arranged inside the box. The box 201 is installed and connected with the flange 304 of the connecting module 30 to drive the box 201 and other components in the box to rotate through the driving motor 302.

[0056] The four corners of the support assembly 202 are provided with legs 2021 for easy placement when the system is not in operation. The electric control box 204 is installed inside the box body 201 to collect the measurement data of the ultra-high voltage transmission line 100 detected by the electric test assembly 205 and the position data of the ultra-high voltage transmission line 100 detected by the camera assembly 2066 in the telescopic mechanism 206.

[0057] When the system performs an electrical inspection on an ultra-ultra-high voltage transmission line 100, the drone 10 takes off with the electrical inspection module 20 and flies above the ultra-ultra-high voltage transmission line 100 to be inspected. The electrical inspection component 205 in the electrical inspection module 20 is slowly deployed at a small angle to detect changes and differences in the ultra-ultra-high voltage transmission line signal, and the drone carrier 10 is flown directly above the ultra-ultra-high voltage transmission line 100. When the controller receives an abnormal electric field signal of the ultra-ultra-high voltage transmission line 100 detected by the electromagnetic sensor 2057, it controls the drone carrier 10 to fly to the abnormal position of the ultra-ultra-high voltage transmission line signal, and sends the generated mechanical deployment signal to the electrical inspection component 205 until the electrical inspection component 205 is fully unfolded, and the camera component 2066 intervenes to detect and perform image recognition to detect whether the ultra-ultra-high voltage transmission line 100 is placed in the test component 205. When the ultra-ultra-high voltage transmission line 100 is not placed in the test component 205, when it is detected that the position result output by the camera component 2066 does not meet the preset value, a corresponding position adjustment signal is generated to enable the test component 205 to control the contact position with the ultra-ultra-high voltage transmission line 100 according to the position adjustment signal. Specifically, the drone carrier 10 drives the test module 20 to descend or rise a certain distance, so that the ultra-ultra-high voltage transmission line 100 is placed in the test component 205, and the system hovers to a position above the ultra-ultra-high voltage transmission line.

[0058] An embodiment of the present invention provides an ultra-high voltage transmission line power testing system based on an unmanned aerial vehicle carrier. For details, see Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 3 The figure shows the internal structure of the electric power testing module of the UAV-based electric power testing system for ultra-high voltage transmission lines in one embodiment of the present invention when the system is not in operation. Figure 4 The figure shows the internal structure of the electric power testing module of the UAV-based electric power testing system for ultra-high voltage transmission lines in one embodiment of the present invention when the system is in working state. Figure 5 The figure shows a side view of an electric power testing module of an ultra-high voltage transmission line electric power testing system based on an unmanned aerial vehicle carrier in one embodiment of the present invention when in working state. Figure 6 Shown is a cross-sectional view of an electric testing module of an ultra-high voltage transmission line electric testing system based on an unmanned aerial vehicle carrier in one embodiment of the present invention when in working state. Figure 6 In the figure, 1 is the electrical testing component 205.

[0059] The electrical testing module includes a box body 201 , a support assembly 202 , an electrical testing assembly 205 , and an electric push rod 203 , an electric control box 204 , and a telescopic mechanism 206 arranged inside the box body.

[0060] The telescopic mechanism includes a stepping motor 2061, a coupling 2062, a screw rod 2063, a horizontal connecting rod 2064 and a driving rod 2065. A through hole is opened in the middle of the horizontal connecting rod 2064. The screw rod 2063 is provided with an external thread, and the through hole is provided with an internal thread matched with the external thread of the screw rod 2063. One end of the screw rod 2063 is connected to the coupling 2062 installed on the stepping motor 2061, and the other end of the screw rod 2063 is connected to the horizontal connecting rod 2064. Driving rods 2065 are provided at both ends of the horizontal connecting rod 2064. One end of the driving rod 2065 is connected to the horizontal connecting rod 2064, and the other end of the driving rod 2065 is hinged to one end of the electrical testing component 205, and the other end of the electrical testing component 205 is connected to the ultra-high voltage transmission line 100.

[0061] Specifically, in this embodiment, when the electrical testing component 205 in the electrical testing module 20 is slowly unfolded at a small angle, the specific unfolding process is: the stepper motor 2061 of the telescopic mechanism 206 drives the screw rod 2063 to rotate, thereby driving the horizontal connecting rod 2064 to move downward relative to the screw rod 2063, and driving the driving rod 2065 at both ends of the horizontal connecting rod 2064 to move downward, and finally drives the electrical testing component 205 connected to the end of the driving rod 2065 to slowly unfold to a preset angle.

[0062] After the ultra-high voltage transmission line 100 is tested, the stepper motor 2061 of the telescopic mechanism 206 rotates in the opposite direction to drive the test assembly 205 to retract, restore the initial state, and continue the subsequent ultra-high voltage transmission line test process or return to the starting point. The process is specifically that the stepper motor 2061 of the telescopic mechanism 206 rotates in the opposite direction and drives the screw rod 2063 to rotate, thereby driving the horizontal connecting rod 2064 to move upward relative to the screw rod 2063, and driving the driving rods 2065 at both ends of the horizontal connecting rod 2064 to move upward, and finally drives the test connecting rod of the test assembly 205 connected to the end of the driving rod 2065 to retract to the initial state.

[0063] An embodiment of the present invention provides an ultra-high voltage transmission line power testing system based on an unmanned aerial vehicle carrier. For details, see Figure 7 , Figure 8 and Fig. 9 , Figure 7 The figure shows a schematic structural diagram of the electric test component of the UAV-based ultra-high voltage transmission line electric test system in one embodiment of the present invention when it is retracted. Figure 8 A schematic diagram showing a front view of an electric testing component of an ultra-high voltage transmission line electric testing system based on an unmanned aerial vehicle carrier in one embodiment of the present invention is shown. Fig. 9 Shown is a cross-sectional view of an electrical testing component of an ultra-high voltage transmission line electrical testing system based on an unmanned aerial vehicle carrier in one embodiment of the present invention.

[0064] In this embodiment, there are two groups of test assemblies 205, and the two groups of test assemblies 205 are centrally symmetrical about the central axis of the chassis 202. Each group of test assemblies 205 is correspondingly connected to the end of the driving rod 2065, and the test assemblies 205 are arranged below the bottom support assembly 202 to drive the test assemblies 205 to expand or retract through the telescopic mechanism 206.

[0065] The electrical testing assembly 205 includes an electrical testing connecting rod 2051 , an electrical testing sheet 2052 , a pressure rod 2053 , a pressure sensor 2058 , an elastic ejecting member 2059 and an elastic restoring member 2050 .

[0066] The electrical test connecting rod 2051 includes a connecting piece 2054, a storage plate 2055 and a receiving piece 2056. The connecting piece 2054 is connected to one end of the storage plate 2055, and the other end of the storage plate 2055 is connected to the receiving piece 2056. A through hole is opened on the connecting piece 2054, and the through hole is adapted to the electric push rod 203. The electrical test sheet 2052 is evenly arranged on the storage plate 2055. The pressure rod 2053 is slidably arranged on the storage plate 2055. A pressure sensor 2058 is arranged on the pressure rod 2053. The pressure sensor 2058 is electrically connected to the electric control box 204. An elastic ejector 2059 is also provided on the pressure rod 2053. The elastic ejector 2059 is adapted to the electric push rod 203. Elastic reset pieces 2050 are evenly spaced on the storage plate 2055.

[0067] Specifically, in this embodiment, the connecting member 2054 is rotatably connected to the supporting assembly 202, and the upper portion of the connecting member 2054 is connected to the driving rod 2065 in a hinged manner.

[0068] A second snap-in slot for snapping in the electromagnetic sensor 2057 is provided at the connection between the storage plate 2055 and the object holder 2056, so as to detect the signal changes and differences of the ultra-ultra-high voltage transmission line through the electromagnetic sensor 2057, and enable the drone to fly directly above the ultra-ultra-high voltage transmission line 100, and the ultra-ultra-high voltage transmission line 100 is placed between the two electromagnetic sensors 2057 of the electrical testing module 20, and the object holder 2056 is used to carry the ultra-ultra-high voltage transmission line 100. A through hole 20541 is provided on the connecting piece 2054 for the electric push rod 203 to pass through. An elastic ejector 2059 is also provided on the pressure rod 2053. The elastic ejector 2059 is adapted to the through hole 20541 to eject the pressure rod 2053 so that the pressure rod 2053 presses the ultra-high voltage transmission line 100. The elastic ejector is a spring. A U-shaped clamping groove is formed between the pressure rod 2053 and the placement plate 2055 of the test connecting rod 2051 and the supporting piece 2056 for clamping the ultra-high voltage transmission line 100.

[0069] The test piece 2052 is installed on the storage plate 2055 of the test rod 2051 and can move elastically relative to the storage plate 2055 to allow the supporting object 2056 to carry the ultra-high voltage transmission line 100. After the ultra-high voltage transmission line 100 squeezes the test piece 2052, the pressure rod 2053 slides downward along the storage plate 2055 and presses the ultra-high voltage transmission line 100.

[0070] After the electric field test piece 2052 measures the electric field data of the ultra-ultra-high voltage transmission line 100, it is uploaded to the electric control box 204 in real time to obtain real-time dynamic electric field data, so as to collect electric field signals, perform noise filtering preprocessing on the collected electric field signals, convert the electric field analog signals into digital signals, and upload the data to the monitoring system of the electric control box to store and back up the data in real time. The data is monitored in real time through multiple safety thresholds set in the monitoring system, and it is determined whether the collected data exceeds the threshold. If it exceeds the threshold, it is abnormal, and then an alarm is triggered to notify the ground operator. If it is normal, a data report is generated after data analysis and processing, and the electric test is regularly calibrated according to the analysis results to end the electric test of the ultra-ultra-high voltage transmission line.

[0071] Specifically, a plurality of elastic return members 2050 are provided on the storage plate 2055, and the test piece 2052 abuts against the elastic return member 2050, and the test piece 2052 can move relative to the elastic return member 2050. A locking groove 20521 is formed between the upper part of the test piece 2052 and the extension section 2055 of the test connecting rod 2051 for installation in cooperation with the pressure rod 2053. In this embodiment, a plurality of elastic return members 2050 are arranged at equal intervals, and the elastic return member 2050 adopts a coil spring, which is not specifically limited here.

[0072] The pressure rod 2053 is slidably disposed on the storage plate 2055 of the test rod 2051 . The pressure rod 2053 is provided with a locking protrusion 20531 to correspond to the locking groove 20521 between the test piece 2052 and the storage plate 2055 .

[0073] A pressure sensor 2058 is provided at the lower part of the pressure rod 2053 for receiving pressure data of the ultra-high voltage transmission line 100 . When the ultra-ultra-high voltage transmission line 100 is mounted on the object-bearing part 2056 of the test rod 2051 and the test piece 2052 is squeezed, the elastic reset part 2050 also contracts and squeezes, and the locking protrusion 20531 on one side of the pressure rod 2053 disengages from the locking groove 20521. At the same time, the elastic ejection part 2059 at the bottom of the connecting part 2054 ejects the pressure rod 2053, so that the pressure rod 2053 presses the ultra-ultra-high voltage transmission line 100. After the pressure sensor 2058 at the bottom of the pressure rod 2053 receives the pressure data of pressing the ultra-ultra-high voltage transmission line 100, the stepping motor 2061 of the telescopic mechanism 206 stops rotating, and the electric push rod 203 opens and continues to hold the pressure rod 2053, so as to further press the ultra-ultra-high voltage transmission line 100 and prevent the ultra-ultra-high voltage transmission line 100 from falling off.
