An underwater cable bridge

Abstract

The invention discloses an underwater cable bridge, which comprises an upper connecting plate and a lower supporting plate which are engaged with each other. A cavity with a rectangular vertical section is formed between the upper connecting plate and the lower supporting plate. The upper and lower ends of the cavity are respectively provided with supporting lifting mechanisms fixed on the bottom wall of the upper connecting plate and the top wall of the lower supporting plate. A group of horizontal and transverse cable placement cylinders are clamped between the two supporting lifting mechanisms, and the cables The placement barrel is hollow, and a supporting placement ring is provided at the center of the barrel openings at both ends. The outer side of the supporting placement ring is clamped with a plurality of cable separation mechanisms that are supported on the inner wall of the cable placement barrel. The cable tray for underwater use forms a double layer of protection for the cables, avoiding the contact between the cables and the water on the outside, improving the waterproof effect of the cable placement, and at the same time, the cables can be placed in different categories to avoid cross-winding when multiple groups of cables are placed at the same time .

Description

technical field [0001] The invention belongs to the technical field of cable bridges, and in particular relates to an underwater cable bridge. Background technique [0002] The cable tray is a device used to fix cables. The cable tray is generally divided into trough type, tray type, ladder type and grid type. The cable tray can be erected independently in the building or laid on the pipe gallery support. Cable Bridges are widely used in industries such as electric power, chemical industry and communication. [0003] The cable tray used underwater, because the surface passes through water, if the waterproof performance is poor, it will cause water seepage inside the bridge, so that the cable is in a humid environment, and in serious cases, it will be soaked in water, which will affect the power supply status. However, the current cable tray is waterproof. The effect is relatively general. After water seeps into the cable bridge, it is easy to contact with the cables. At the...

Problems solved by technology

[0003] The cable tray used underwater, because the surface passes through water, if the waterproof performance is poor, it will cause water seepage inside the bridge, so that the cable is in a humid environment, and in serious cases, it will be soaked in water, which will affect the power supply status. However, the current cable tray is waterproof. The effect is relatively general. After water seeps into the cable bridge, it is easy to contact with the cables. At the same time, when multiple sets of cables are placed and installed, they are also easy to mix and wind, which affects subsequent maintenance, inspection and replacement.
