Description

Technical Field

[0001] This utility model relates to cable conduit sealing technology, and in particular to a device for sealing 10 kV cable conduits. Background Technology

[0002] With the rapid development of the power industry and the information industry, environmental protection issues have gradually attracted people's attention. Underground cabling has been widely promoted in the construction and renovation of urban power grids, leading to the increasingly widespread application of cable conduits. Cable conduits are devices that protect cables, distinguish cable functions, and facilitate wiring and maintenance. In the process of power construction, 10KV cable conduits are pre-buried underground to facilitate the wiring of 10KV cables. After the cable conduits are pre-buried, the pipe ends need to be sealed to prevent rainwater or other foreign objects from entering the interior of the conduit and affecting the wiring.

[0003] Existing sealing methods generally use tape for sealing. However, tape is easily damaged, requires repeated wrapping, and is inconvenient to remove, resulting in inconvenient construction. Therefore, this utility model proposes a cable conduit sealing device that is easy to install or disassemble and has a relatively secure fixation to meet the existing needs. Utility Model Content

[0004] The purpose of this utility model is to provide a device for sealing 10 kV cable conduits, which solves the problems of inconvenient installation or disassembly and insufficient secure fixing of existing cable conduit sealing tools.

[0005] To address the aforementioned issues, this utility model provides a pre-installed kilovolt cable conduit sealing device, comprising a cover slidably connected inside a sealing tube. The sealing tube can be inserted into one end of the cable conduit. The inner side of the sealing tube has multiple cross grooves arranged in a circular array. A cross member is slidably connected within the cross grooves. One side of the cross member can abut against the inner wall of the cable conduit, and the other side of the cross member can extend into the sealing tube and is fixed with an arc-shaped block. The edge of the cover extending into the sealing tube can abut against multiple arc-shaped blocks. A stud is threadedly connected to the axis of the cover. A circular plate is fixed to one end of the stud extending into the cover, and one side of the circular plate can abut against one end of the sealing tube.

[0006] The pre-installed kilovolt cable conduit sealing device provided by this utility model also has the following technical features:

[0007] Furthermore, the cross-shaped component includes a cross block and an anti-slip pad, the anti-slip pad being able to abut against the inner wall of the cable conduit.

[0008] Furthermore, a guide block is fixed inside the plug, and a guide groove is provided on the cover, allowing the guide block to slide within the guide groove.

[0009] Furthermore, the stepped surface of the cross block is connected to the plug via a spring.

[0010] Furthermore, the stepped surface of the cross block is connected to the plug via a spring.

[0011] Furthermore, a bolt is threaded onto one side of the outer casing, and one end of the bolt can abut against one side of the cover.

[0012] This utility model has the following beneficial effects: By inserting the plug into one end of the cable conduit, fixing the plug in place, and rotating the stud, one side of the circular plate abuts against one end of the plug. The cover slides inside the plug, allowing the edge of the cover extending into the plug to abut against multiple arc-shaped blocks and push the arc-shaped blocks to move. This causes multiple cross-shaped parts to abut against the inner wall of the cable conduit, thereby fixing the position of the plug. The plug and cover can seal one end of the cable conduit, and the device can be installed or removed by rotating the stud. Construction is convenient, and the fixation is relatively reliable.
