[0028] Refer to Figures 1-3, an embodiment provided by the present utility model: a movable horizontal telescopic connection pipe extraction and recovery device, including an offshore construction platform 1, on the upper end of the offshore construction platform 1 there is a crane 2, on the top of the crane 2 there is a vibratory hammer 3 installed, on one side of the offshore construction platform 1 there is a well pipe 10, at the bottom of the vibratory hammer 3 there is a connecting rod 4 connected, on the outer wall of the connecting rod 4 there is a hydraulic oil pipe 5 installed, at the bottom of the connecting rod 4 there is a pipe extractor 6 installed, inside the pipe extractor 6 there is a telescopic slider 8 arranged, at the rear of the telescopic slider 8 there is a pushing oil cylinder 9 installed, and at the bottom of the pipe extractor 6 there is a guide head 7.

[0029] In the present utility model, the crane 2 is fixedly installed on the top of the offshore construction platform 1, the offshore construction platform 1 is horizontally positioned on the water surface, the well pipe 10 is fixedly installed on one side of the offshore construction platform 1, and the well pipe 10 is installed inside the soil.

[0030] Furthermore, the vibratory hammer 3 is connected to the top side of the crane 2 through a hook, the connecting rod 4 is integrally installed at the bottom of the vibratory hammer 3, the hydraulic oil pipe 5 is fixedly installed on the outer wall of the connecting rod 4, the hydraulic oil pipe 5 is communicated with the inside of the connecting rod 4, there is a pipe inside the connecting rod 4 connected to the hydraulic oil pipe 5, and the pipe extraction device head is provided with a movable horizontal telescopic slider, which can freely enter and exit the underwater vertical well pipe when retracted. After entering the well pipe, the horizontal telescopic slider can extend and connect with the well pipe, so that the vibration of the upper part of the device can be conducted to the well pipe through the connecting rod, driving the well pipe to vibrate, and then vibrating and lifting (the crane) to extract the well pipe.

[0031] Furthermore, the guide head 7 is integrally installed at the bottom end of the pipe extractor 6.

[0032] Furthermore, at the bottom of the connecting rod 4 there is a pipe extractor 6 installed, inside the pipe extractor 6 there is a telescopic slider 8 arranged, at the rear of the telescopic slider 8 there is a pushing oil cylinder 9 installed, the number of the pushing oil cylinders 9 is four, and the design of the guide head 7 not only facilitates the pipe extractor to enter the well pipe, but also enhances its stability and guiding property during work, enabling it to more flexibly adapt to various working environments and improving work efficiency.

[0033] The fixed installation of the pushing oil cylinder 9 ensures its stability and reliability during work. The setting of the four pushing oil cylinders 9 not only improves the connection reliability between the pipe extractor and the well pipe, but also makes the force more uniform, thus avoiding deformation or damage of equipment materials caused by uneven force. At the same time, this design also makes the work of the pipe extractor 6 more stable and improves the pipe extraction efficiency.

[0034] The movable connection design between the pipe extractor 6 and the jacking oil cylinder 9 enables the pipe extractor 6 to flexibly adjust its position as needed to adapt to different working requirements. This design not only improves the flexibility of use of the pipe extractor 6 but also makes the entire equipment more adaptable to complex working environments.

[0035] As for the telescopic slider 8, it is movably connected to the outside of the bottom of the connecting rod 4 and is connected to the pipe extractor 6. This design enables the telescopic slider 8 to expand and contract according to the position change of the pipe extractor 6, thus ensuring that the pipe extractor 6 always remains in the optimal working position.

[0036] Working principle and its usage process: Transport the movable horizontal telescopic connection pipe extraction and recovery device of the present utility model to the site where the well pipe needs to be recovered, and horizontally position the water construction platform 1 on the water surface. The crane 2 is fixedly installed on the top of the water construction platform 1 to perform the lifting and lowering of the equipment during the recovery process.

[0037] When the recovery starts, start the crane 2 to vibrate the connecting rod 4 through the vibratory hammer 3. Since the hydraulic oil pipe 5 is internally connected to the connecting rod 4, hydraulic oil can enter the interior of the connecting rod 4 through the hydraulic oil pipe 5 to provide power for the jacking oil cylinder 9. Driven by the hydraulic oil, the jacking oil cylinder 9 starts to push the telescopic slider 8 outwards. The telescopic slider 8 stops after moving to the inner wall of the well pipe 10, and the pipe extraction device on the crane 2 temporarily clamps and anchors the telescopic slider 8 to the pipe flange of the well pipe 10.

[0038] After the pipe extractor 6 is clamped and anchored to the well pipe, start the pipe extraction operation.

[0039] During the pipe extraction process, the vibration of the vibratory hammer 3 helps to loosen the bond between the well pipe 10 and the soil, making the pipe extraction operation smoother. At the same time, the mobility of the telescopic slider 8 can adapt to well pipes 10 of different diameters, enhancing the versatility and practicality of the present utility model.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
