[0013] A method for testing a power line direct current remote measuring device comprises the following steps:

[0014] S1. Insert the connecting pipe into the ground through the excavation plate, rotate the dispersion ring to push the buried pipe deep into the ground through the sawtooth groove, and receive the power harmonics emitted by the underground cable through the test core. The power harmonics are received by the receiver.

[0015] S2. The power harmonics are received by the receiver through the connecting pipe into the telegraph pole, and then radiated outward from the telegraph pole and received by the signal converter. The signal converter converts the power harmonics into radio wave signals, which then pass through the signal pole and enter the signal chip. The signal chip contacts the surface of the conductive block and sends the radio wave signals to the information receiver.

[0016] S3. The radio wave signal enters the battery cell on the surface of the contact tube from the information receiver for signal collection, and is sent into the rotating arm through the contact between the guide ring and the surface of the battery cell. After the fixed block is loosened by hand, the angle of the rotating arm can be adjusted by rotating the rotating arm on the surface of the rotating rod.

[0017] S4. Pull the pulling plate and drag it outward. The test plate is dragged outward by the rotation of the retractable plate 1 and the retractable plate 2 on the retractable rod 1 and the surface of the retractable rod. The radio wave signal enters the load-bearing box from the rotating arm, and then is transmitted from the load-bearing box to the surface of the test plate to emit the radio wave signal outward. The radio wave signal is then transmitted outward to the remote signal station and received.

[0018] S5. When the rainy season is about to come, pull the pull button to retract the test board into the retractable box, drag the handle to pull the slider outward through the slide slot, and pull the cover plate fixed on the surface of the push rod from the inner wall of the retractable plate to cover the surface of the test board. Compared with the prior art, the present invention provides a power line DC current remote sensing device and a test method thereof, which have the following beneficial effects:

[0019] 1. The present invention sets up an underground device, inserts the connecting pipe into the ground through the digging plate, rotates the dispersion ring to push the buried pipe deep into the ground, and receives the power harmonics emitted by the underground cable through the test core. By setting up the above mechanism, the electric harmonics emitted by the underground cable can be collected more accurately.

[0020] 2. The present invention sets up dispersion components, and the power harmonics are absorbed by the receiver and entered into the telecommunication pole for reception. The telecommunication pole radiates the power harmonics outward and is received by the signal converter, and is converted into radio wave signals by the signal converter. The radio wave signals enter the signal chip, and the signal chip contacts the surface of the conductive block to send the radio wave signals to the information receiver. By setting up the above mechanism, the radio wave signals can be transmitted outward at multiple angles so that the signal station can receive the signals in time.

[0021] 3. The present invention sets a rotating component and a telemetry component, and the radio wave signal enters the contact tube from the information receiver for signal collection. The radio wave signal is sent to the rotating arm. After the fixed block is loosened by hand, the pulling plate is pulled and dragged outward. After the test plate is dragged outward, the radio wave signal enters the load-bearing box from the rotating arm, and then is transmitted from the load-bearing box to the surface of the test plate to emit the radio wave signal outward. The radio wave signal is then transmitted outward to a remote signal station and received. By setting the above mechanism, the frequency and propagation range of the radio wave signal can be expanded.

[0022] 4. The present invention sets a covering component, drags the pull button to retract the test board into the retractable box, drags the outside of the handle to pull it out, and pulls the covering plate fixed on the surface of the push rod out from the inner wall of the retractable plate to cover the surface of the test board. By setting the above mechanism, the test board can be prevented from being disturbed by rain outdoors and affecting its transmission signal. BRIEF DESCRIPTION OF THE DRAWINGS
