Description

Technical Field

[0001] This utility model relates to the field of cable replacement technology, and more specifically to the field of detachable number tube box technology. Background Technology

[0002] Using cable number tubes to mark important information about cables is a common practice in power production system equipment maintenance and is also a process that needs to be repeated during equipment modification and replacement.

[0003] The safe and stable operation of hydropower stations relies heavily on numerous control panels, which contain extensive wiring. The accuracy of the cable numbering tubes is crucial for the safe and stable operation of the turbine generator units. When equipment malfunctions and requires troubleshooting, workers must locate the problem on-site by referring to drawings and the cable numbering tubes on the equipment. If discrepancies exist between the drawings and the actual wiring, the correctness of the numbering tubes is paramount for timely identification. If an error is found, the tubes must be replaced immediately. During equipment upgrades or modifications at hydropower stations, a large number of cable numbering tubes need to be replaced—ranging from dozens to thousands per generator unit. Inadequate record-keeping during the upgrade process can lead to multiple replacements of the same cable numbering tubes, resulting in repetitive work, increased workload, and increased worker fatigue.

[0004] Currently, every time a number tube is replaced, the cable terminal block needs to be remade, which doubles the time spent on replacing the number tube. If the terminal block is remade, there is a possibility that the old cable is not long enough and the cable needs to be re-laid, which increases the workload of the operators.

[0005] Therefore, in order to address the shortcomings of the current method of replacing number tubes which requires additional cable fabrication steps, a detachable number tube box is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a detachable number tube box in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model provides a detachable number box, including a lower number box unit and an upper number box unit arranged symmetrically. The lower number box unit and the upper number box unit cooperate to form a cable through hole for placing cables. The lower number box unit and the upper number box unit are locked on both sides by detachable connectors.

[0009] The lower number box unit and / or the upper number box unit are provided with a label placement part for placing label paper, and a protective cover is provided outside the label placement part.

[0010] Specifically, when this solution requires cable replacement, the lower number box unit and the upper number box unit can be disassembled, which can eliminate the cable fabrication process caused by replacing the number tubes, greatly simplifying the workload of replacing number tubes and improving the efficiency of staff in replacing number tubes.

[0011] In one embodiment, the upper number box unit is a rectangular block structure, and a first semi-circular through groove is provided at the bottom of the upper number box unit along the length direction.

[0016] In one embodiment, the detachable connector is a snap-fit ​​assembly, which includes a locking groove hinged to the bottom side of the upper number box unit and a locking block disposed at the top side of the lower number box unit, the locking groove being adapted to the locking block.

[0017] In one embodiment, the detachable connector is a plug-in connector, which includes a plug-in groove fixed to the bottom side of the upper number box unit and a plug-in block disposed on the top side of the lower number box unit, with the plug-in groove cooperating with the plug-in block.

[0018] In one embodiment, the bottom of the insertion slot extends beyond the bottom side of the upper number box unit, and the top of the insertion block is flush with the top side of the lower number box unit.

[0019] In one embodiment, the label placement section includes a strip groove recessed along the length of the top of the upper number box unit for placing label paper, the depth of the strip groove being greater than the thickness of the label paper.

[0020] Specifically, similarly, the label placement section includes a strip groove recessed along the length direction at the bottom of the lower number box unit for placing label paper, the depth of the strip groove being greater than the thickness of the label paper.

[0021] In one embodiment, the protective cover is a square protective plate hinged to one edge of the slot, and the square protective plate is locked to the other edge of the slot away from the hinge end by a detachable locking assembly.

[0022] Specifically, the detachable locking component can be a regular snap-fit ​​structure or a plug-in structure that facilitates locking.

[0023] In one embodiment, the square protective plate is made of one of the following materials: polyvinyl chloride plate, acrylic plate, polycarbonate plate, or glass plate.

[0024] In one embodiment, both the lower number box unit and the upper number box unit are made of insulating material.
