Abstract
The invention relates to an offshore (river) sinking pipe tunnel construction technology, and discloses an underwater cable protective device. The device comprises a fixation plate. The fixation plate is detachably installed at the tail end of a pipe section and is provided with a first arc groove for installing a cable. The device further comprises a pressure plate. The pressure plate is connected with the fixation plate and fixes the cable in the first arc groove. According to the invention, the tail end of the pipe section is provided with the fixation plate with the arc groove for fixing the cable, so that the cable is prevented from being bent at the tail end of the pipe section, and the damage to the cable is avoided accordingly; and furthermore, the fixation plate is installed by use of a plugging member, so that during dismounting of the cable, a diver only needs to rapidly pull out a connection latch to dismount the underwater cable, thus the underwater workload is reduced.

Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Hereinafter implement
Example is used for the present invention is described, but is not limited to the scope of the present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of underwater cable protection device of the present invention, including fixed plate 1, this fixed plate 1
It is removably mounted on tube coupling tail end, fixed plate 1 is provided with the first arcuate groove 11 for installing cable 2.
In order to preferably cable 2 be positioned fixation, to avoid cable under flow action to depart from the first arcuate groove 11, this enforcement
Example also includes pressing plate 3, and this pressing plate 3 is connected with fixed plate 1 and cable 2 is fixed in the first arcuate groove 11, and pressing plate 3 passes through bolt
It is fixed on fixed plate 1.
Pressing plate 3 is spliced by the sub- pressing plate of polylith 31.Sub- pressing plate 31 is provided with the second arcuate groove that can accommodate cable 2
311, cable 2 is located between the first arcuate groove 11 and the second arcuate groove 311.
Wherein, the outer surface of the part that cable 2 is contacted with fixed plate 1 is enclosed with insulating barrier 4, on the one hand avoids cable 2 He
Abrasion between fixed plate 1, on the other hand prevents cable 2 from leaking electricity.Insulating barrier 4 is made using soft rubber.Will be absolutely using nylon tape 5
Edge layer 4 tightens and is fixed on cable 2.
