Technical Field

[0001] The utility model relates to the technical field of power design, and particularly relates to a protection device. Background Technique

[0002] Power design is an important step in the construction process. A reasonable power design can facilitate the normal and smooth power supply of the building. When laying power cables, a protection device is needed to protect the power cables at the initial position on the building, avoiding the problem that the power cables are crushed due to workers walking or vehicle transportation.

[0003] A line protection device for power design disclosed in the existing patent with the publication number CN218335265U includes a protective cover. Two bases are symmetrically and fixedly installed at the bottom of the protective cover. A plurality of rubber blocks are also fixedly glued at the middle position of the bottom of the protective cover. An equal-distance gap is maintained between the plurality of rubber blocks, and card wire grooves are formed on the surfaces of the rubber blocks. The card wire grooves are circular structures.

[0004] In the above document, through the provided protective cover and the cooperating rubber blocks, the cable can be clamped into the clamping groove during wiring, and then the protective cover is laid on the ground, which can achieve the effect of safely protecting the cable and prevent the cable from being crushed and damaged.

[0005] However, the power cables in the above document are in contact with the ground. The environment on the construction site is complex, and the protected power cables are prone to moisture, affecting the use effect of the power cables. At the same time, in the above document, the power cables are directly sleeved for protection, which is inconvenient for quickly taking out the power cables after protection. Therefore, we propose a protection device to solve the problems raised above. Content of the Utility Model
