[0021] The technical scheme in the utility model will be described below in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0022] DETAILED DESCRIPTION: As Figures 1-5As shown, the present embodiment discloses a power cable rat bite protection structure, which comprises a first protective layer 1, a second protective layer 2 and a third protective layer 3. The first protective layer 1 is tightly fitted outside the power cable body 4, the second protective layer 2 is tightly fitted outside the first protective layer 1, and the third protective layer 3 is tightly fitted outside the second protective layer 2.
[0023] Further, the first protective layer 1 comprises a hard protective sleeve 1 5 and a plurality of rat spikes 6. The hard protective sleeve 1 5 is tightly fitted on the outer wall of the power cable body 4, and the plurality of rat spikes 6 are evenly distributed along the circumference of the outer wall of the hard protective sleeve 1 5 and cover the entire outer wall of the hard protective sleeve 1 5.
[0024] Further, the second protective layer 2 comprises a first rat net 7, a second rat net 8 and a plurality of rat repelling boxes 9. The second rat net 8 is tightly fitted outside the first protective layer 1, the second rat net 8 is fitted outside the first rat net 7, and a plurality of rat repelling boxes 9 are arranged between the first rat net 7 and the second rat net 8.
[0025] Further, the rat repelling box 9 comprises a box body 10 and a rat repelling substance 12 arranged inside the box body 10. The side wall of the box body 10 is provided with a plurality of odor dispersing holes 1 1.
[0026] Further, the third protective layer 3 comprises a hard protective sleeve 2 13 and a corrosion-resistant plating layer 14. The hard protective sleeve 2 13 is tightly fitted outside the first rat net 7, and the corrosion-resistant plating layer 14 is arranged on the outer wall of the hard protective sleeve 2 13.
[0027] Hard protective sleeve 1 5: The hard protective sleeve 1 5 is made of high-density polyethylene (HDPE) or polypropylene (PP) and other high-strength, wear-resistant and aging-resistant thermoplastic materials, and is prepared by extrusion molding process. It has good mechanical properties and chemical stability, and can effectively resist the bite of rodents and the erosion of the external environment.
[0028] Rat spikes 6: The rat spikes 6 are made of stainless steel or hard plastic, and are in the shape of sharp cones or triangles. They are evenly distributed on the outer wall of the hard protective sleeve 1 5 by hot melting or mechanical fixing. The length and spacing of the rat spikes 6 are designed according to the size and behavior of rodents to ensure that they can effectively prevent rodents from climbing and biting.
[0029] First rat net 7 and second rat net 8: Made of stainless steel wire or high-strength nylon fiber, the mesh size is smaller than the minimum passing size of rodents to prevent them from penetrating. At the same time, the diameter and weaving density of the wire should be sufficient to ensure strength and durability to resist the tearing and biting of rodents and the damage of the external environment.
