CORE SAMPLING APPARATUS AND CONTAINER TRANSFER APPARATUS

摘要

Provided is a core sampling apparatus which maintains the internal pressure after the core drilling.;The core sampling apparatus includes a barrel part, a container which is movably disposed in the barrel part and maintains the sampled core, a ball valve to prevent a fluid from inflowing and outflowing between an inside and an outside of the barrel part in a closed state thereof, a first seal member which seals a space between the barrel part and the ball valve, a second seal member which seals a space between the container and the barrel part, a locking mechanism which locks a state in which the ball valve is sealed by the first seal member, and an inflowing mechanism configured to inflow the fluid only in a direction to an internal space of the closed barrel part by the first seal member and the second seal member.

主权项

1. A core sampling apparatus which samples a core, comprising:
a barrel part; a container which is movably disposed in the barrel part in an axial direction of the barrel part and maintains the sampled core; a ball valve which is disposed at one opening portion side of the barrel part to prevent a fluid from inflowing and outflowing between an inside and an outside of the barrel part through the one opening portion in a closed state thereof; a first seal member which seals a space between the one opening portion of the barrel part and the ball valve in the state that the ball valve is closed; a second seal member which seals a space between an outer peripheral surface of the container and an inner peripheral surface of the barrel part when the container is positioned at a specific position in the axial direction of the barrel part; a locking mechanism which locks a state in which the ball valve is sealed by the first seal member; and an inflowing mechanism configured to inflow the fluid only in a direction to an internal space of the closed barrel part by the first seal member and the second seal member, wherein the inflowing mechanism comprises at least one of a check valve disposed at a position between the internal space of the barrel part and an outside thereof, and the second seal member which is a lip seal.
