PIPELINE SUPPORT PROTECTIVE DEVICE Russian patent published in 2019 - IPC E02B15/02 E01D18/00 F16L3/00 

FIELD: storage or distribution of gases or liquids.

SUBSTANCE: invention relates to the pipeline transport, in particular to the pipeline supports through water barriers protective devices. Objective of this invention is to increase the durability and reliability of pipeline supports in the conditions of the impact of ice drift, timber drifting, river pumps and other extraneous floating objects, and also the extension of the scope of application of a protective device to pipeline supports through water barriers. Protection device of the pipeline support includes a vertical part of the support rigidly connected with the bolt supporting the pipeline, the foundation grillage, and the ice-cutting part. New is the fact that the ice-cutting part is a metallic protective sheath, in cross section having a triangular shape, which can rotate around the vertical part of the support by means of an electric, hydraulic, pneumatic or other drive. Inventive protective device supports the pipeline performs two functions: protects the supporting structures of the support from the effects of ice drift, timber drifting, other extraneous floating objects; does not allow ice masses, products of the timber drifting, and other floating objects to get hooked on the support, thereby preventing the formation of river jams.

EFFECT: technical result consists in increasing the durability and reliability of pipeline supports under the influence of an ice drift, a timber drifting, river pumps and other extraneous floating objects.
