Outdoor UV protection bridge

Abstract

The invention discloses an outdoor anti-ultraviolet bridge, which comprises a tank body with an opening in the top, and a cover plate for covering the opening of the tank body, wherein a left rotating shaft is arranged at the top of the left side wall of the tank body; two ends of the left rotating shaft are connected with the left side wall through support seats separately; a right rotating shaft is arranged at the top of the right side wall of the tank body and two ends of the right rotating shaft are connected with the right side wall through support seats; the cover plate comprises a left plate body and a right plate body which are arranged in opening and closing manners; the left side of the left plate body is provided with a left sleeve which rotationally sleeves the left rotating shaft; a torsional spring is arranged between the left rotating shaft and the inner wall of the left sleeve; the right side of the right plate body is provided with a right sleeve which rotationally sleeves the right rotating shaft; a torsional spring is also arranged between the right rotating shaft and the inner wall of the right sleeve; and the outer walls of the tank body and the cover plate are provided with an anti-ultraviolet layer. The bridge with the structure is reliable in structure and good in anti-ultraviolet effect, furthermore, the construction capacity can be reduced and the construction difficulty can be reduced in the using process.

Description

technical field [0001] The invention relates to a cable bridge used on roads or expressways, in particular to an outdoor anti-ultraviolet bridge. Background technique [0002] Due to the heavy weight and easy corrosion of metal cable trays, the cable trays currently used on roads or expressways have been gradually replaced by non-metallic materials. For example, the announcement number is CN103244753A and the announcement number is CN103606864A, which discloses a kind of cable bridge with polyurethane composite material, both of which are made of non-metallic materials. The common advantages of this type of bridge are light weight, The production cost is low, and it is not easy to corrode. The disadvantages are: in order to facilitate the penetration of cables, they are all combined structures, that is, the tank and the cover can be detachably connected. body, and the solid connection between the tank body and the cover body is achieved through bolts. This method not only i...

Problems solved by technology

For example, the announcement number is CN103244753A and the announcement number is CN103606864A, which discloses a kind of cable bridge with polyurethane composite material, both of which are made of non-metallic materials. The common advantages of this type of bridge are light weight, The production cost is low, and it is not easy to corrode. The disadvantages are: in order to facilitate the penetration of cables, they are all combined structures, that is, the tank and the cover can be detachably connected. body, and the solid connection between the tank body and the cover body is achieved through bolts. This method not only increases the amount of construction and increases the difficulty of construction, but also easily damages the cables during the process of screwing in the bolts.

In addition, the existing bridge frame has poor anti-ultraviolet effect, resulting in a short service life
