FIELD: geophysics.
SUBSTANCE: present invention relates to geophysical equipment, especially in area of seismic survey and seismic data collection. More specifically, invention relates to systems for collecting seismic data, comprising a cable network connected to a central information processing device located, for example, on a vehicle. Disclosed group of inventions includes load removing device for installation on geophysical equipment or network node, load removing node and seismic data collection line. Load removing device for installation on geophysical equipment or network node, to which is connected at least two cables, comprises a housing, configured to surround geophysical equipment or network node and equipped with first and second openings for cables to facilitate connection between corresponding cable from said at least two cables and geophysical equipment or network node and housing to accommodate part of each of each of two cables, wherein housing is configured to prevent displacement of parts of two cables, wherein housing has opposite first and second lateral sides and forms a first path for cable passing through first lateral side, through inner space of housing, through second lateral side and then back loop through first opening for cable for connection with geophysical equipment or network node, as well as a second path for cable passing through second lateral side, via inner space of housing, through first lateral side and then back loop through second opening for cable for connection with geophysical equipment or network node.
EFFECT: technical result consists in creation of an external load removing device, which provides reliable protection of geophysical equipment or network node from bending loads, especially in case of operations in transition zones, and having small dimensions of loops of cables compared to existing engineering solutions, which reduces risk of impacts on loops during operations, and also improves water tightness of equipment and its protection against mechanical effects, prevents damage of cables connected with close coverage at point of attachment to cable has small dimensions and small weight.
