8. The cable pay-off and take-up device according to claim 1, wherein the diameter of the inner wall of the cable cavity (100) is greater than or equal to 270 mm.
9. The cable reel of claim 1,
the outer side surface of the outer arc plate (12) is welded with a mounting connecting frame (4) which is used for being in butt joint with the telescopic arm;
the cable winding and unwinding device further comprises a controller, the stepping motor (2) is a planetary reduction stepping motor, and the controller is electrically connected with the stepping motor (2).
10. A cable reeling method using the cable reeling device according to any one of claims 1 to 9, wherein the reeling method includes the steps of:
step S1: before use, the free end of the cable is led in from a threading hole (120) on the side surface of the cable storage disc (1) and wound in a cable cavity (100), wherein the length wound in the cable cavity (100) is not less than the maximum extending amount of the telescopic arm, and the winding direction of the cable is clockwise;
step S2: after the cable is wound, the free end of the cable penetrates out of a cable guide hole (335) and is connected with a radar device, wherein the free end of the cable is connected with a holder at the top of the telescopic arm through a buckle;
step S3: the controller sends a restraining instruction to the stepping motor (2), the stepping motor (2) loses the holding torque, the cable winding and unwinding device enters a state capable of feeding the cable, the telescopic arm stretches out at the moment, and the cable winding and unwinding device is in a state of feeding the cable;
step S4: the telescopic arm drives the free end of the cable to extend outwards, the free end of the cable pulls the whole cable to extend outwards to form the cable storage disc (1), a torque adjusting wheel (35) of the cable guide mechanism (3) passively rotates anticlockwise under the stretching action of the cable, and the cable continuously extends out through a cable guide hole (335);
step S5: the controller controls the stepping motor (2), wherein the recovery speed of the stepping motor (2) is faster than the falling speed of the cable:
step S6: the stepping motor (2) positively rotates for a period of time, and the stepping motor (2) actively pulls the cable into the cable cavity;
step S7: the cable is wound in the annular space (10) of the cable storage disc (1) through the cable guide hole (335);
step S8: when the inner wall of the cable storage disc (1) is wound with the cable for more than one circle, the stepping motor (2) rotates reversely for a period of time, so that the cable tightened on the inner wall of the cable storage disc (1) is released to the bottom;
step S9: and (4) repeating the steps S6 to S8, wherein the stepping motor (2) rotates forwards and backwards periodically, and the cables are continuously stored in the annular space (10) of the cable storage disc (1) until the cables are completely recycled or the annular space (10) is full of the cables.
