[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.
[0024] Example 1:
[0025] In this embodiment, if Figure 1-3 As shown, the utility model proposes a highly weather-resistant MPP electric power protection tube, including a base layer 3, the outer wall of the base layer is bonded to the inner wall of the waterproof layer 2, the outer wall of the waterproof layer is provided with an anti-corrosion layer 1, the inner wall of the base layer is bonded to the outer wall of the supporting layer 4, the inner wall of the supporting layer is bonded to the outer wall of the fireproof layer 5, the inner wall of the fireproof layer is bonded to the outer wall of the protective layer 6, a mounting plate 7 is provided in the protective layer, and a cable 8 is passed through the mounting plate.
[0026] In the present embodiment, it is further configured that the anti-corrosion layer is an anti-corrosion coating, and the anti-corrosion coating is covered on the outer wall of the waterproof layer. The anti-corrosion coating has good corrosion resistance and weather resistance, and also has heat reflection performance.
[0027] In this embodiment, it is further configured that the waterproof layer, the base layer, the support layer, the fireproof layer and the protective layer are arranged from the outside to the inside, and their diameters decrease successively.
[0028] In this embodiment, a plurality of concave points 61 are further arranged on the inner wall of the protective layer, and the protective layer is elastic.
[0029] In this embodiment, it is further configured that a plurality of protrusions 71 are provided on the outer edge of the mounting plate, and the protrusions are matched and snap-fitted with the concave points. When in use, one of the protrusions of the mounting plate is installed corresponding to the concave point. Since the protective layer has elasticity, the mounting plate is pressed into the pipe so that the remaining protrusions of the mounting plate are installed corresponding to the concave points.
[0030] In this example, the concave points can also be set as grooves, and the number of the concave points is symmetrically distributed around the circumference, but the distance between the concave points should not be too close, and the number of the concave points must be greater than the number of the convex points.
[0031] In this embodiment, it is further configured that the diameter of the mounting plate is smaller than the inner wall diameter of the protective layer, and the outermost extension of the protrusions at both ends of the mounting plate corresponding to 180 degrees is greater than the inner wall diameter of the protective layer and smaller than the outer wall diameter of the protective layer, so as to facilitate the fixing of the mounting plate.
[0032] In this embodiment, it is further configured that a plurality of through holes 72 are provided on the surface of the mounting plate, the through holes are matched with the cables, and the diameter of the through holes is larger than the diameter of the cables.
[0033] Example 2:
[0034] In this embodiment, if Figure 3-4 As shown, the through holes on the surface of the mounting plate are arranged according to actual needs, and the through holes are sufficient for passing the cables.
[0035] like Figure 3 Shown is a mounting plate where all through-holes have the same diameter and are symmetrically distributed to avoid crossing of cables.
[0036] like Figure 4 The invention relates to a mounting plate, wherein the diameter of the central through hole of the mounting plate is larger than that of the other through holes, the central through hole is used to mount the main cable, and the other through holes are used to pass the other cables.
[0037] The working principle of the highly weather-resistant MPP power protection pipe is that the anti-corrosion layer and the waterproof layer have good corrosion resistance, waterproof performance and weather resistance. They can reduce the corrosion of the power protection pipe caused by rainwater under rain erosion and sunlight, slow down the aging of the power protection pipe under wind, rain and sunlight, and extend the life of the power protection pipe. The base layer and the supporting layer are the skeleton to provide structural strength for the power protection pipe. The fireproof layer can prevent the fire in the pipeline from affecting the outside world. The protective layer can buffer the external pressure to prevent damage to the cable caused by impact. The protective layer and the mounting plate can be clamped to fix the mounting plate. The mounting plate can allow multiple cables to pass through the mounting holes separately without gathering together, which is beneficial to the heat dissipation of the cables.
