SUMMERY OF THE UTILITY MODEL

For solving above-mentioned current difficult problem, the utility model provides a practicality is high, low cost, thereby can effectually prevent the ageing security and the life of increasing the cable of cable protection pipe to with the ageing resistance cable protection pipe of crookedness control in order to be applicable to installation and user demand of cable in suitable within range.

The utility model adopts the following technical scheme: the utility model discloses ageing resistance cable protection pipe, including the cable protection pipe main part that cavity set up, cable protection pipe main part cover is located on the cable, cable protection pipe main part includes fire-retardant thermal-insulated inlayer, crooked protective layer and glass steel outer layer, fire-retardant thermal-insulated inlayer, crooked protective layer and glass steel outer layer overlap from inside to outside and locate on the cable in proper order, and glass steel has light high strength, corrosion-resistant, tensile strength is strong, yielding, characteristics such as heat conductivity are low, can effectively prevent the harm of external mechanical stress, corruption, high temperature to the cable, prevents cable protection pipe main part's ageing, and can effectively support necessary bending when the cable installation, crooked protective layer hugs closely glass steel outer layer and sets up, be equipped with crooked recess and crooked arch between crooked protective layer and the fire-retardant thermal-insulated inlayer, crooked recess and crooked arch are interval arrangement distribution along the circumferencial direction of crooked protective layer in proper order, when the cable protection tube main body is bent, the two adjacent bent bulges are extruded mutually to prevent the outer layer of the glass fiber reinforced plastic from being excessively bent, and the outer layer of the glass fiber reinforced plastic and the cable are protected.

Furthermore, the surface of the outer layer of the glass fiber reinforced plastic is coated with an anti-aging agent, so that the damage of ultraviolet rays, wind, sand, rain, snow, chemical media and the like to the outer layer of the glass fiber reinforced plastic can be prevented, and the aging of the cable protection pipe body can be further prevented.

Further, the bending protection layer is a heat-resistant rubber layer, so that damage to the cable is further reduced under the condition that the bending protection layer is protected from high temperature.

Further, the flame-retardant heat-insulation inner layer is a high-expansibility glass fiber sleeve layer.

Furthermore, the thick iron oxide red silica gel layer covers the outer portion of the flame-retardant heat-insulation inner layer, and damage to the cable caused by long-term high temperature and flame can be effectively prevented.

Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the anti-aging cable protection tube has simple structure, reasonable design and low cost, the cable protection tube adopts the outer layer made of the glass fiber reinforced plastic material to effectively prevent external mechanical stress, corrosion, high temperature and the like from infringement, and can support necessary bending during cable installation, the anti-aging agent on the surface of the outer layer of the glass fiber reinforced plastic further prevents the aging problem of the cable protection tube, the service life of the cable protection tube is prolonged, the arrangement of the bending protection layer effectively avoids the damage of the cable core wire caused by excessive bending of the cable protection tube, simultaneously carries out bending protection on the outer layer of the glass fiber reinforced plastic and the cable core wire, the arrangement of the bending protection layer tightly attached to the outer layer of the glass fiber reinforced plastic can increase the shear strength of the cable protection tube, reduces the use thickness of the outer layer of the glass fiber reinforced plastic to be more easily bent, effectively isolates various high temperatures from damaging the cable under the double-combination, under above integrated configuration's setting, the effectual durability and the security that have improved the cable of prior art to be applicable to the installation demand of cable, reduced the cost of maintenance of cable, certain popularization and application meaning has.
