The beneficial effect of the utility model as follows: with the help of the characteristics of laser high -energy, utilize highly -compressed air to form local air dielectric cavity, realize that laser cuts the sheathed tube, need not artifical dive or robot operation, it is with low costs, fast, pollute for a short time to marine environment.
Description
Technical field
The utility model relates to a kind of casing cutting device, particularly a kind of casing cutting device under water based on laser.
Background technology
After marine petroleum exploitation completes, the sleeve pipe be embedded on sea bed must cut, and prevents from causing damage to boats and ships and other underwater navigation equipment.Mainly adopt machine cuts to the cutting of sleeve pipe at present, need artificial diving or robot manipulating task, length consuming time, cost is high, comparatively serious to marine pollution.The utility model, by the high-octane feature of laser, utilizes pressure-air to form local air dielectric cavity, realizes the cutting of laser to sleeve pipe, and without the need to manually diving under water or robot manipulation, cost is low, and speed is fast, little to marine environmental pollution.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, provide a kind of casing cutting device under water based on laser, by the high-octane feature of laser, pressure-air is utilized to form local air dielectric cavity, realize the cutting of laser to sleeve pipe, without the need to manually diving under water or robot manipulation, cost is low, speed is fast, little to marine environmental pollution.
Its technical scheme is: a kind of casing cutting device under water based on laser, primarily of driving source, drilling rod, sleeve pipe, top cement plug, laser head, bottom plug, resonator and pore composition, described driving source and resonator rely on the cable being arranged on drilling rod inside to be connected, driving source provides electric excitation energy for resonator, described resonator is connected with laser head, laser head to be arranged on drilling rod and to be positioned at top cement plug and bottom plug center, described drilling rod is coaxial with sleeve pipe, top cement plug and bottom plug are installed bottom drilling rod, described top cement plug and bottom plug are collar plate shape rubber elastic material, top cement plug and bottom plug and internal surface of sleeve pipe close contact, top cement plug, bottom plug, independent annular space is formed between drilling rod and internal surface of sleeve pipe, described bottom plug is provided with some plug holees, described drilling rod is positioned at top cement plug bottom and is provided with the some array pores of a circle.
During casing cutting device work under water, first flow through drill pipe bore by pressure-air and enter top cement plug by pore, bottom plug, annular space between drilling rod and internal surface of sleeve pipe, the plug hole of annular space internal liquid by bottom plug is extruded by air-flow, top cement plug, bottom plug, annular air medium is formed between drilling rod and internal surface of sleeve pipe, described driving source by high energy electric excitation by being arranged on the cable transfer of drilling rod inside to resonator, electric excitation excites the working media of intra resonant cavity and is amplified by resonator and sends superlaser by laser head, superlaser transmits and melts internal surface of sleeve pipe in annular air medium, slow rotation drilling rod, laser head skew certain distance, the internal surface of sleeve pipe laser cutting of a week can be realized.
