DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-6 In the present embodiment, an automated TL hand-release tool comprises a straight tube 1 and a horizontal plate 9. The front left and right sides of the inner wall of the straight tube 1 are respectively fixedly connected to the left and right sides of the horizontal plate 9. A first circular ring 4 is fixedly connected to the front of the outer wall of the straight tube 1. A second circular ring 5 is fixedly connected to the rear of the outer wall of the straight tube 1. Both the first circular ring 4 and the second circular ring 5 are made of rubber material to play a sealing role. The outer walls of the first circular ring 4 and the second circular ring 5 are connected to a control structure 2. The inner wall of the horizontal plate 9 is connected to an adjustment structure 3. A first connecting port 8 is inserted at the rear of the inner wall of the straight tube 1. A shear nail 7 is fixedly connected to the top of the straight tube 1. The shear nail 7 will break when subjected to thrust. A second connecting port 10 is inserted at the front end of the outer wall of the straight tube 1. A through port 6 is processed at the top of the straight tube 1.

[0023] The control structure 2 includes a sleeve 201 and a bent rod 202. The inner wall of the sleeve 201 is fitted with the outer walls of the first ring 4 and the second ring 5 at the front and rear sides respectively. The top rear of the sleeve 201 is fixedly connected to the bottom of the bent rod 202. The outer wall of the bent rod 202 is slidably connected with a round block 203. The bent rod 202 is forced to slide forward and backward through the inner wall of the round block 203. The bottom of the round block 203 is fixedly connected with a vertical rod 204. The outer wall of the vertical rod 204 is sleeved with a spring 204. 5. The two ends of the spring 205 are respectively fixed to the bottom of the round block 203 and the top of the straight tube 1. After the round block 203 is forced to move downward, it rebounds by the elastic force of the spring 205. The lower part of the outer wall of the vertical rod 204 is slidably engaged with the rear part of the top of the straight tube 1. The vertical rod 204 is forced to slide up and down through the rear part of the top of the straight tube 1. The lower part of the outer wall of the vertical rod 204 is plugged into the top of the first connecting port 8, and the front part of the top of the sleeve 201 is plugged into the outer wall of the shear nail 7.

[0024] When the oil in the control structure 2 fills the interlayer, the sleeve 201 will move forward on the outer wall of the straight pipe 1, and the moving sleeve 201 will break the shear nail 7. The moving sleeve 201 will cause the bent rod 202 to gradually separate from the inner wall of the round block 203. At this time, the spring 205 will lose pressure. After losing pressure, the spring 205 provides a rebound force to move the round block 203 outward with the vertical rod 204, so that the inner side of the outer wall of the vertical rod 204 is separated from the outer wall circular opening of the first connecting port 8, and then the straight pipe 1 is pulled upward to separate it from the first connecting port 8, completing the automatic hand-releasing work, changing the original control form, avoiding the use failure of the TL hand-releasing tool, and ensuring the normal use of the TL hand-releasing tool.

[0025] The adjustment structure 3 includes a screw rod 301 and a handle 302. The front of the outer wall of the screw rod 301 is threadedly connected to the inner wall of the horizontal plate 9. The screw rod 301 is subjected to force to rotate back and forth through the inner wall of the horizontal plate 9. The front of the screw rod 301 is fixedly connected to the rear end face of the handle 302. The handle 302 is convenient for driving the screw rod 301 to rotate. The rear of the outer wall of the screw rod 301 is rotatably connected with a ball 303. The rear of the outer wall of the screw rod 301 is subjected to force to rotate through the front bearing of the ball 303. The outer wall of the ball 303 is plugged into the rear of the inner wall of the straight tube 1.

[0026] Working principle:

[0027] The inner wall of the second connection port 10 is plugged into the oil pipe, and the first connection port 8 is plugged into the wellhead.

[0028] Automated TL hand-off work:

[0029] The oil pipe delivers the oil into the straight pipe 1 through the second connecting port 10, and finally flows out at the opening 6 on the outer wall of the straight pipe 1. The oil will gradually fill the interlayer between the straight pipe 1 and the sleeve 201. When the oil fills the interlayer, the sleeve 201 will move forward on the outer wall of the straight pipe 1. The moving sleeve 201 will break the shear nail 7. The moving sleeve 201 will cause the bent rod 202 to gradually separate from the inner wall of the round block 203. At this time, the spring 205 will lose pressure. After losing pressure, the spring 205 provides a rebound force to make the round block 203 move outward with the vertical rod 204, so that the inner side of the outer wall of the vertical rod 204 separates from the outer wall circular opening of the first connecting port 8, and then pulls the straight pipe 1 upward to separate it from the first connecting port 8, completing the automatic hand-release work.

[0030] Positioning of the ball:

[0031] When oil needs to be poured into the inner wall of the straight tube 1, the handle 302 is used to rotate the screw rod 301 backward on the inner wall of the horizontal plate 9, and the rotating screw rod 301 moves the ball 303 backward, so that the outer wall of the ball 303 fits with the raised part of the inner wall behind the straight tube 1, completing the sealing of the inner wall behind the straight tube 1 and the positioning of the ball 303 at the same time.

[0032] Embodiment 2:

[0033] See also Figure 1-6 In this embodiment, an automated TL hand-release tool further includes a bracket 11 and a bolt 12. The bottom of the bracket 11 is fixedly connected to the top front of the straight pipe 1, and the top of the bracket 11 is threadedly connected to the bolt 12.

[0034] Working principle:

[0035] When the second connection port 10 is plugged into the front end of the outer wall of the straight pipe 1, the bolt 12 is rotated downward through the bracket 11, so that the bottom of the bolt 12 is pressed against the top of the second connection port 10, thereby increasing the connection stability between the second connection port 10 and the straight pipe 1.

[0036] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
