Abstract
Description
Technical Field
[0001] This invention relates to the field of cable box technology, and more particularly to a portable cable box for temporary power supply. Background Technology
[0002] Temporary power supply is an essential requirement for construction, equipment maintenance, and other scenarios. However, the current use of temporary power cables on-site has significant drawbacks: First, traditional cable reels lack integrated safety protection devices and are deficient in "one machine, one switch, one protection" configurations, making them prone to safety accidents due to overload, short circuits, and leakage, and lacking effective protective measures. Second, cable winding and unwinding rely on manual dragging, which is laborious, inefficient, and prone to cable tangling and wear, shortening their service life. Third, on-site cables are often laid haphazardly on the ground or suspended in the air, with widespread instances of unauthorized and haphazard installation, which can easily cause people to trip and poses a risk of cable insulation damage and leakage. Fourth, the lack of dedicated fixing methods makes it difficult to properly arrange cables in locations such as railings and walkways, failing to ensure insulation and safety of passage, and seriously affecting on-site work order and personnel safety. Summary of the Invention
[0003] The purpose of this invention is to at least partially solve one of the technical problems in related technologies.

[0015] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0016] The portable cable box for temporary power supply according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0017] like Figure 1-4 As shown in the figure, this embodiment of the invention proposes a portable cable box for temporary power supply, including: a housing 3, a cable spool, a motor 1, and a cable. The housing 3 has a cavity inside, and a cable outlet 10 is provided on one side of the housing 3. A handle 11 is connected to the upper end of the housing 3. The cable spool is rotatably connected to the cavity. The cable spool includes a shaft portion 4 and a baffle 5. The baffle 5 is fixedly connected to both ends of the shaft portion 4 to form an I-shaped structure. The motor 1 is installed on one side of the cavity. The output end of the motor 1 is fixedly connected to one end of a rotating shaft 2. The rotating shaft 2 passes through the cable spool in a horizontal direction. The other end of the rotating shaft 2 is rotatably connected through a bearing seat 6. The bearing seat 6 is installed on the side of the cavity opposite to the motor 1. The rotating shaft 2 and the cable spool are connected by a key. The motor 1 drives the cable spool to rotate axially. The cable is wound around the shaft portion 4, and the end of the cable extends out of the housing 3 through the cable outlet 10. The motor 1 drives the cable spool to rotate, thereby driving the cable to be output out of the cable outlet 10.
[0018] The present invention uses a motor 1 to drive the cable shaft, which facilitates the rapid winding and unwinding of cables, avoids cable tangling and wear, eliminates the need for manual dragging, and improves work efficiency.
[0019] Furthermore, motor 1 is a reversible motor, which facilitates the winding and unwinding of cables.
[0020] Furthermore, a plug is connected to the end of the cable for power connection. The cable is equipped with a circuit breaker, a residual current device (RCD), and an independent switch, forming an integrated "one device, one switch, one protection" structure. Direct connection to a power source provides triple protection against overload, short circuit, and leakage. No additional protection equipment is required, avoiding safety hazards caused by unauthorized wiring and ensuring safe and compliant temporary power use. Furthermore, a control panel is connected to the outside of housing 3. The control panel has multiple buttons and is electrically connected to motor 1, circuit breaker, residual current device (RCD), and independent switch. The control panel's outer casing is made of high-strength insulating plastic. The control panel has a display screen that shows real-time information such as power on / off status, protection status, and cable retraction / delay length.
[0021] Furthermore, the control panel is equipped with an emergency braking button, which can quickly cut off the power supply in an emergency to ensure operational safety.
[0022] Furthermore, the circuit breakers, residual current devices, and independent switches are arranged horizontally side by side, with a 10cm interval between adjacent components.
[0023] Furthermore, the cable reel is made of high-strength, lightweight materials, such as aluminum alloy, making it lightweight and easy to move.
[0024] Furthermore, the outer side of the handle 11's grip section is wrapped with an anti-slip rubber sleeve, which has diagonal anti-slip textures.
[0025] Furthermore, baffle 5 has a disc-shaped structure.
[0026] In some embodiments, a clip is connected at the outlet 10 to temporarily secure the cable end.
[0027] In some embodiments, a protective cover is detachably connected to the outside of the outlet 10, which completely covers the end and the clip.
[0028] Furthermore, the protective cover can be detachably connected to the outside of the housing 3 via a plug-in or threaded connection.
[0029] In some embodiments, such as Figure 1 As shown, casters 9 are connected to the four corners of the bottom of the housing 3. This facilitates on-site handling and transfer.
[0030] Furthermore, the 9th swivel wheel is a silent wheel.
[0031] In some embodiments, such as Figure 3 As shown, a groove 12 is provided at the upper end of the housing 3, and a handle 11 is rotatably connected to the groove 12. When the handle 11 is rotated to a horizontal state and placed in the groove 12, the upper surface of the handle 11 is lower than the upper surface of the groove 12. When the handle 11 is rotated to a vertical state, the handle 11 and the bottom surface of the groove 12 are perpendicular to each other, and the upper surface of the handle 11 is higher than the upper surface of the groove 12.
[0032] In some embodiments, such as Figure 1 As shown, the end of the rotating shaft 2 extends out of the bearing seat 6 and to the outside of the housing 3. The extended end of the rotating shaft 2 is fixedly connected to the hexagonal sleeve 7, which is used to be inserted into the manual crank.
[0033] The cable can be wound up or down even when motor 1 is powered off, thanks to the dual manual and electric modes. The control panel features a lever for switching between manual and electric modes.
[0034] Furthermore, a clutch switch can be connected between the output shaft of motor 1 and the rotating shaft 2. When the lever is switched to "manual" mode, the gear set is disconnected from the output end of motor 1, and the manual crank can be connected to the end of rotating shaft 2 for manual cable winding and unwinding. When the lever is switched to "electric" mode, the gear set engages with the output end of motor 1 for electric cable winding and unwinding. Furthermore, the manual crank has an L-shaped structure with a hexagonal interface at one end, which can be inserted into a hexagonal sleeve in 7 directions.
[0035] In some embodiments, such as Figure 1As shown, the housing 3 is detachably connected to the cover 8 at a position located outside the hexagonal sleeve 7.
[0036] Furthermore, the cover 8 is detachably connected to the exterior of the housing 3 via a plug-in or threaded connection.
[0037] In some embodiments, such as Figure 4 As shown, the portable cable box for temporary power supply also includes a manual crank. The side or top of the housing 3 is provided with a slot for placing the manual crank, and the manual crank is engaged with the slot.
[0038] In some embodiments, a magnetic strip is fixedly connected to the cable for temporary fixation to the iron railing by magnetic attraction.
[0039] Furthermore, the external connections of the cable have anti-slip pads.
[0040] Furthermore, insulating straps are equidistantly connected to the cable.
[0041] Furthermore, the cable can be temporarily secured to the iron railing using an adjustable magnetic clip. The adjustable magnetic clip is C-shaped and made entirely of insulated plastic, with a neodymium iron boron magnet attached to the inside. The opening width of the clip is adjustable to fit railings with a diameter of 5-10cm. In use, the clip is placed over the cable and the outside of the railing. The double attraction of the magnetic strip and the neodymium iron boron magnet further prevents the cable from slipping off the railing. The magnetic force of the magnetic strip and the neodymium iron boron magnet is ≥5N, ensuring it adheres to the iron railing.
[0042] In some embodiments, the housing 3 is made of aluminum alloy.
[0043] The usage process of the portable cable box for temporary power supply according to an embodiment of the present invention: (1) Preparation: Move the cable box to the work site using the handle 11 or casters 9. Select a three-phase or single-phase power supply according to the power requirements, connect it to the input terminal of the integrated protection module, and ensure that the interface connection is firm. Connect motor 1 to the power supply.
[0044] (2) Safety protection start: When the independent switch is turned on, the status display unit lights up, and the circuit breaker and leakage protection device automatically enter the working state, monitor the circuit current and leakage in real time. Once an overload, short circuit or leakage occurs, the power supply will be automatically cut off to avoid safety accidents.
[0045] (3) Cable layout: Pull out the required length of cable and select the fixing method according to the site environment. If it needs to be fixed to iron railings, use the magnetic strip of the cable to directly attach it, or use the matching adjustable magnetic buckle to reinforce it. If it needs to be arranged on both sides of the walkway, use insulating tape to fix the cable to the preset point to ensure that the cable is insulated off the ground and does not affect passage.
[0046] (4) Cable winding and unwinding operation: After the operation is completed, start the mechanical winding and unwinding mechanism. You can choose the manual mode by turning the manual crank, or choose the electric mode by turning on motor 1. The transmission gear set drives the cable shaft to rotate, so as to realize the automatic winding and unwinding of the cable and avoid tangling and wear.
[0047] (5) Emergency and Status Monitoring: During operation, the display screen provides real-time feedback on the power supply status and protection status. An automatic alarm will sound if any abnormality occurs. In case of emergency, pressing the emergency brake button will quickly cut off the power supply to ensure personnel safety. After the operation is completed, turn off the control switch and disconnect the power interface.
