83 SAFETY MECHANISM FOR INSTALLATION IN SOIL-SAMPLING TOOLING, WITH A SYSTEM FOR BLOCKING THE ESCAPE OF GAS/OIL IN THE STAGE OF RECOVERING THE INTERNAL TUBE CONTAINING THE SPECIMEN US15100623 2013-11-28 US20160312558A1 2016-10-27 Antonio Sergio CAVALHEIRO; Mario Cesar PEREIRA DOS SANTOS; Leandro Diniz Brandao ROCHA; Hamilton SUSS JUNIOR; Jose Roberto SCALON COTELLO; Ronaldo SOARES EISELE
“SECURITY MECHANISM FOR INSTALLATION IN SOIL DRILLING TOOLS, WITH GAS/OIL LEAKAGE LOCKING SYSTEM ON RECOVERY STAGE OF INTERNAL TUBE CONTAINING TOKEN”, where a mechanism for installation on drilling equipment tooling (which uses barrel for the continuous token extraction), be developed with a cable gland assembly (1), connectors (22), (32) and valve (42). With such elements, the mechanism offers a sealing system that prevents, in the recovery step of the inner tube with the token, that there is oil or gas leakages. The mechanism also has an additional safety device (52). Thus, the tooling typically used for ore survey (simpler and cheaper) may be used in wells for gas/oil drilling, bringing remarkable benefits in the segment, both in operationally and commercial level.

An O-ring seal between the shaft and the top cap receptacle forms a seal preventing the bore contents leaking out or the ambient environment leaking in. The plug has two rotational locks to prevent unauthorized removal. One is a platform with an aperture extending from the upper portion of the shaft receiving a threaded fastener preventing rotation through radially extending vertical top cap structures. The other is a cantilevered platform, with an aperture for a padlock preventing rotation by the shafts side wing members.
