Rubber short tube with alarm device

Abstract

The invention relates to a short rubber pipe used on a dredger and used for delivering silt on inner pipelines of a cabin, in particular to a short rubber pipe with a warning device. The device comprises a rubber pipeline and pipe joints arranged at the two ends of the rubber pipeline, wherein the rubber pipeline adopts a multi-layer structure composed of an inside liner, wear-resistant steel rings which are uniformly arrayed and spaced at a certain interval and are embedded in the inside liner, a skeleton layer covering the outer surface of the inside liner, and an outer coating layer used for coating the outer surface of the skeleton layer, which are all arranged from inside to outside; a conducting wire used for uniformly winding the whole outer surface of the inside liner is arranged between the inside liner and the skeleton layer; the two joints of the conducting wire penetrate through the skeleton layer and the outer coating layer and are connected onto the external warning device, so that the short rubber pipe is capable of detecting the wear of the short rubber pipe.

Description

technical field [0001] The invention relates to a short rubber pipe on a dredger used for conveying sediment on a pipeline in a cabin, in particular to a short rubber pipe with an alarm device. Background technique [0002] The pipes in the cabin of the dredger are generally connected with short rubber pipes for length compensation, shock absorption and convenient connection. During the process of conveying sand and sand, the rubber short pipe will be worn away slowly until it is broken. [0003] Because the short rubber tube is very inconvenient to disassemble and its service life is affected by different conveying media, it is difficult to accurately grasp the replacement time of the short rubber tube. Due to the high pressure and velocity of the sediment in the pipeline, once the short rubber tube is damaged and causes leakage, the cabin will be filled with sediment and water in a short period of time. If the control is not good, the ship will sink into the water. In th...
