The outer wall of the core tube 7 is provided with a core tube buckle 703 (the buckle is opened and closed by a mechanical spring and is kept to be popped out in a normal state), and the core tube buckle can be matched with a clamping groove 602 on the inner wall of an axial through hole 601 in the self-submersible drilling machine 6 to realize clamping and locking. The core barrel buckle 703 is connected to a contact switch 704 provided at the bottom of the connection hole 702 via a control circuit (or a mechanical transmission mechanism).
In this embodiment, the core barrel joint 803 has two structural forms, a core barrel joint i and a core barrel joint ii, and a blind hole 8031 is formed in the end portion of the lower end of the core barrel joint i.
When the core tube connector II is clamped in the connecting hole 702, the lower end of the core tube connector II abuts against a contact switch 704 (shown in figure 8), and the contact switch 704 controls the core tube buckle 703 to retract; when the core tube connector I is clamped in the connecting hole 702, the lower end of the core tube connector I abuts against the hole bottom of the connecting hole 702, the contact switch 704 is located in the blind hole 8031, so that the core tube connector I is not contacted with the contact switch 704 (fig. 7), and the core tube buckle 703 keeps the original opening state.
As shown in fig. 9, the core pipe joint 803 in this embodiment includes a joint body, and the joint body includes a telescoping mechanism i, a locking mechanism, a retainer ring rotating mechanism, and a retainer ring 8037 in this order from bottom to top. The telescopic mechanism I comprises a telescopic rod I8033 which is axially arranged along a rock core pipe joint, and a spring I8034 is sleeved on the telescopic rod I. The buckle mechanism is provided with a spring tube 8036 and a joint buckle 8035 matched with the joint clamping groove 705, the lower end of the joint buckle is rotatably hinged with the joint body, and the upper end of the joint buckle is connected with the joint body through the spring tube. The retainer ring rotating mechanism is provided with a telescopic rod II 80310 arranged along the axial direction of the rock core pipe joint and a spring II 80311 sleeved on the telescopic rod II, and the lower part of the telescopic rod II is provided with a circle of guide teeth 8039 facing upwards. The check ring 8037 is coaxially and rotatably arranged on the connector body, a plurality of notch grooves for the connector buckle 8035 to pass through are uniformly formed on the check ring, a blocking piece is formed between each notch groove and the corresponding notch groove, and the check ring is provided with driven teeth 8038 matched with the lower guide teeth.

When the gravity hammer sleeve 801 falls down along the rope 802 and impacts the core barrel joint 803, the telescoping mechanism I is compressed first, the part of the core barrel joint 803 above the telescoping mechanism I moves downwards, and the joint buckle 8035 compresses the spring tube 8036 under the action of downward impact force and the supporting force of the lower edge of the clamping groove 705 and penetrates through the notch groove on the retainer ring to retract inwards.
After the telescopic mechanism I is compressed, a spring II and a telescopic rod II in the check ring rotating mechanism are also compressed under the action of impact force, and the check ring 8037 moves downwards again. The driven teeth 8038 are gradually meshed with the guide teeth 8039 below in the downward moving process of the retainer ring 8037, and because the driven teeth 8038 and the guide teeth 8039 are staggered by a certain angle at the beginning, the driven teeth 8038 rotate by a certain angle under the action of the guide teeth in the downward moving process, and the driven teeth 8038 drive the retainer ring 8037 to rotate by a certain angle. After the retainer ring 8037 rotates, the notch groove of the retainer ring is staggered from the connector buckle 8035, and is blocked by the blocking piece and cannot be spread outwards.
When the connector buckle 8035 needs to be unfolded outwards again, the retainer ring 8037 can be manually rotated after the core barrel connector 803 is taken out, so that the notch groove of the retainer ring corresponds to the connector buckle 8035 in position.
