Abstract
Description
Technical Field
[0001] This invention relates to the technical field of cables, and particularly to the technical field of power cables. Background Technology
[0002] Power cables are cables that provide power to various devices. They are generally thicker in diameter and heavier in weight. The effective length of existing power cables is generally fixed, which is not suitable for occasions or situations where the effective length of the power cable needs to be varied.
[0003] Existing patent CN117748237A discloses a retractable cable connector and method, which can extend the cable connector by pulling the cable joints at both ends as needed; however, since it requires manual pulling, there is a certain safety hazard when the cable is energized.
[0004] Existing patent CN115117814A discloses a retractable cable guide device and an aircraft including the device. The retractable cable guide device, which uses a three-sleeve, three-clamp form, can better prevent cable tangling, facilitate maintenance, and prevent cable breakage; however, its cable length adjustment range is relatively small. Summary of the Invention
[0005] The purpose of this invention is to solve the problems in the prior art by proposing a retractable and adjustable power cable that allows the power cable to be automatically adjusted in effective length with a wide adjustment range.
[0006] To achieve the above objectives, this invention proposes a retractable and adjustable power cable, comprising a remote-controlled platform vehicle, a mounting box, a winding shaft, a first servo motor, a cable exit frame, a push-pull mechanism, and a cable exit ring. The remote-controlled platform vehicle is equipped with a mounting box, inside which is a winding shaft connected to a first servo motor. A separator ring is fixed in the middle of the winding shaft, and a through hole is provided on the separator ring for the cable body to pass through. The cable body is wound around the winding shaft, with the winding directions on both sides of the separator ring being opposite. Two elongated cable exit frames are installed on the wall of the mounting box, with the length of the cable exit frames parallel to the winding shaft. The two cable exit frames are located on opposite sides of the cable body. A cable exit ring is provided inside each cable exit frame, and both ends of the cable body pass through the two cable exit rings respectively. A push-pull mechanism is installed inside each cable exit frame, connected to the cable exit ring, and the push-pull mechanism drives the cable exit ring to move along the length direction of the cable exit frame.
[0007] Preferably, the first servo motor is located outside the mounting box.
[0008] Preferably, the inner diameter of the outlet ring is larger than the outer diameter of the cable body, and the cross-section of the outlet ring is circular.
[0009] Preferably, the mounting box is a rectangular box with two cable outlet frames located on two opposite side walls of the mounting box. The side walls where the cable outlet frames are located are parallel to the winding shaft. The inlet and outlet ends of the cable outlet frames are located inside and outside the mounting box, respectively. The inlet and outlet ends of the cable outlet ring are located on the opposite sides of the inlet and outlet ends of the cable outlet frames.
[0010] Preferably, the push-pull mechanism consists of a second servo motor, a screw, a guide rod, a nut, and a guide sleeve. A second servo motor is installed inside the cable outlet frame, and a screw driven by the second servo motor is installed inside the cable outlet frame. A nut that mates with the screw is fitted on the screw. A guide rod is installed inside the cable outlet frame, and a guide sleeve that slides along the guide rod is fitted on the guide rod. Both the screw and the guide rod are parallel to the length direction of the cable outlet frame, and both the nut and the guide sleeve are fixed to the cable outlet ring.
[0011] Preferably, the nut and guide sleeve are fixed at the upper and lower ends of the lead ring, respectively.
[0012] Preferably, an exhaust fan is installed on the top wall of the mounting box, with the air inlet of the exhaust fan connected to the inside of the mounting box and the air outlet of the exhaust fan connected to the outside of the mounting box.
[0013] Preferably, the outer diameter of the cable loop formed by the cable body wound around the winding shaft is smaller than the outer diameter of the separator ring.
[0014] Preferably, the first servo motor, the push-pull mechanism, and the remote-controlled platform vehicle are controlled by a single control device.
[0015] The beneficial effects of the present invention are as follows: The present invention winds the cable body on a winding shaft with opposite winding directions on both sides of the separator ring. The effective length of the cable body can be adjusted by rotating the winding shaft. The push-pull mechanism and the lead-out ring cooperate with each other to prevent the cable body from being pressed during winding.
[0016] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

[0019] Example 1: See Figure 1 , Figure 2 The present invention relates to a retractable and adjustable power cable, comprising a remote control platform vehicle 1, a mounting box 2, a winding shaft 3, a first servo motor, a cable outlet frame 4, a push-pull mechanism, and a cable outlet ring 5. The remote control platform vehicle 1 is equipped with a mounting box 2, and a winding shaft 3 is provided inside the mounting box 2. The winding shaft 3 is connected to a first servo motor. A separator ring 31 is fixed in the middle of the winding shaft 3. A cable through hole 32 is provided on the separator ring 31 for the cable body to pass through. The cable body is wound on the winding shaft 3, and the winding direction of the cable body on both sides of the separator ring 31 is opposite.
[0020] To avoid the cable bodies on both sides of the separator ring 31 pressing against each other, the outer diameter of the cable loop formed by the cable body wound on the winding shaft 3 is smaller than the outer diameter of the separator ring 31.
[0021] Two elongated cable outlet frames 4 are installed on the wall of the mounting box 2. The length of the cable outlet frames 4 is parallel to the winding shaft 3. The two cable outlet frames 4 are located on both sides of the cable body. A cable outlet ring 5 is provided inside the cable outlet frame 4. The two ends of the cable body pass through the two cable outlet rings 5 respectively. A push-pull mechanism is installed inside the cable outlet frame 4. The push-pull mechanism is connected to the cable outlet ring 5. The push-pull mechanism drives the cable outlet ring 5 to move along the length of the cable outlet frame 4.
[0022] The first servo motor is located outside the mounting box 2.
[0023] To facilitate the control of the device, the first servo motor, the push-pull mechanism, and the remote-controlled platform vehicle 1 are controlled by a single control device.
[0024] Example 2: To prevent the cable body 1 from being scratched by the cable exit ring 5, the inner diameter of the cable exit ring 5 is larger than the outer diameter of the cable body, and the cross-section of the cable exit ring 5 is circular.
[0025] To prevent the cable body 1 from being scratched by the cable outlet frame 4, the mounting box 2 is a rectangular box. The two cable outlet frames 4 are located on two opposite side walls of the mounting box 2. The side wall where the cable outlet frame 4 is located is parallel to the winding shaft 3. The inlet end and outlet end of the cable outlet frame 4 are located inside and outside the mounting box 2, respectively. The inlet end and outlet end of the cable outlet ring 5 are located on the opposite sides of the inlet end and outlet end of the cable outlet frame 4.
[0026] Example 3: To ensure smooth movement of the cable outlet ring 5 via the push-pull mechanism, the mechanism comprises a second servo motor 40, a screw 41, a guide rod 43, a nut 42, and a guide sleeve 44. A second servo motor 40 is installed inside the cable outlet frame 4, along with a screw 41 driven by the second servo motor 40. A nut 42, which mates with the screw 41, is fitted onto the screw 41. A guide rod 43 is installed inside the cable outlet frame 4, and a guide sleeve 44, which slides along the guide rod 43, is fitted onto the guide rod 43. Both the screw 41 and the guide rod 43 are parallel to the length direction of the cable outlet frame 4. The nut 42 and the guide sleeve 44 are both fixed to the cable outlet ring 5.
[0027] The nut 42 and the guide sleeve 44 are respectively fixed at the upper and lower ends of the wire outlet ring 5.
[0028] Example 4: To ensure the heat dissipation of the cable body inside the mounting box 1, an exhaust fan 20 is installed on the top wall of the mounting box 2. The air inlet of the exhaust fan 20 is connected to the inside of the mounting box 2, and the air outlet of the exhaust fan 20 is connected to the outside of the mounting box 2.
[0029] Working process of this invention: During operation, the remote-controlled platform vehicle 1 can move the power cable to the required position, making the arrangement of the power cable more flexible. When the effective length of the power cable needs to be adjusted, the first servo motor drives the winding shaft 3 to rotate. As the winding shaft 3 rotates, the cable body is unwound or wound up, and the effective length of the cable body changes. During the rotation of the winding shaft 3, the second servo motor 40 drives the screw 41 to rotate. The screw 41 drives the nut 42 and the lead-out ring 5 fixed to the nut 42 to move, so that the length of the cable body in the installation box 2 is as small as possible, and the wire pressing phenomenon can be avoided during winding.
[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
