fig. 2 is a schematic structural view of a protection device for laying power cables in a preferred embodiment of the present invention.
Detailed Description
The invention is further described with reference to the drawings and the detailed description.
A protection device for laying power cables, referring to figures 1 to 2, comprises a carrying frame 5, a ring device 2 and a fixing piece; the annular device 2 is provided with an abdicating hole, and the cable 1 passes through the abdicating hole; the length of two sides of the carrying frame 5 is longer than the diameter of a well channel 4 into which the cable 1 extends, and the carrying frame 5 is carried on the well mouth of the well channel 4; particularly, the carrying frame 5 specifically comprises two carrying bars side by side, the periphery of the annular device 2 is respectively fixedly connected with the angle steel 3, and the angle steel 3 is arranged along the vertical direction. The edge of the annular device 2 has a certain safety distance to the hole wall of the abdicating hole, and the safety distance enables the cable 1 to pass through the abdicating hole and enter the well channel 4 without touching the inner wall of the well channel 4.
In this embodiment, the angle iron 3 is provided with four, and four top angles of the ring device 2 are sequentially and fixedly connected with one angle iron 3. Two angle steels 3 are fixedly arranged on one carrying strip, the distance between the two angle steels 3 on the carrying strip is the length of the annular device 2, and the distance between the carrying strips is the width of the annular device 2. All be provided with first connecting hole around ring device 2, angle steel 3 is provided with first connection mating holes, passes through first connecting piece first connecting hole and first connection mating holes realize ring device 2 is connected with dismantling of angle steel 3. The second connecting hole is formed in the carrying frame 5, the second connecting matching hole is formed in the angle steel 3, and the second connecting piece penetrates through the second connecting hole and the second connecting matching hole to achieve detachable connection of the carrying frame 5 and the angle steel 3.
