Coupling device for seismic sensors

摘要

A coupling device is provided for a sensor unit having at least one sensor located within a housing. The coupling device includes at least one supporting portion, wherein the supporting portion is configured for maintaining the sensor unit in a stable position, with the coupling device either resting on or being buried into the ground, and at least one rod, arranged in a plane which is essentially perpendicular to a peripheral surface of the supporting portion and linked to the supporting portion. The coupling device further includes a fastener for connecting the sensor unit to the coupling device. The supporting portion maintains the sensor unit in a stable position when resting on the ground, while the rod provides an additional stiffness to the housing.

1. A coupling device for a sensor unit comprising at least one sensor located within a housing, wherein the coupling device includes:
at least one supporting portion, said supporting portion being configured for maintaining the sensor unit in a stable position with the coupling device either resting on or being buried into the ground, wherein said at least one supporting portion comprises:
at least a first supporting portion against which said housing is to be maintained in position; anda second supporting portion having a peripheral section essentially parallel to a peripheral section of the first supporting portion, wherein the second supporting portion is configured to be placed on the ground when the coupling device rests on the ground or to be within the ground when the coupling device is buried into the ground, and at least one rod, arranged in a plane which is essentially perpendicular to the plane of the first and second supporting portions, said first and second supporting portions being linked together by said at least one rod,
a third supporting portion upon which an end of the housing is to be fastened, said third supporting portion is placed between the first and second supporting portions, the supporting portions being separated by spaces, and a fastener configured to connect the sensor unit to the coupling device, wherein said at least one sensor is a digital seismic sensor.
