Description
Technical field
The utility model relates to oil field, specifically refers to a kind of oil well underground fishing structure.
Background technology
In oil well operation process; the junk that some affect operation and oil exploitation usually can be fallen in oil well; be generally the elongated and object that body is soft such as some wire rope, cable, steel wire for logging, these junks need pull out in oil well in time, in order to avoid soil-well jam or damage equipment.Drag for rope instrument inner for oil well rope form junk to be pulled out though present, but it is low not only to salvage efficiency, and salvages thorough not, many tiny, things not easily salvaged that drops that length is shorter, cause the salvaging cycle also to extend.
Utility model content
The purpose of this utility model is to provide a kind of oil well underground fishing structure, the rope instrument that drags in the past of solving salvage efficiency low, salvage halfway problem.
The purpose of this utility model is achieved through the following technical solutions:
A kind of oil well underground fishing structure, comprise the support column of inner hollow, the sidewall of described support column has multiple rectangular opening, the bottom of support column has multiple spacing hole interconnective with rectangular opening, the hollow cavity internal fixtion of support column has the support bar of taper, is connected with multiple claw at the sidewall upper hinge of described support bar; Also comprise the electromagnet being fixed on supporting bar top, electromagnet is connected with external power source by wire, and on the side of support bar, be provided with the magnet matched with electromagnet at claw.During utility model works, rectangular opening and spacing hole form the L shape activity interval of claw on support bar, support column is slowly put into oil well, start power supply simultaneously, magnet on electromagnet and claw is interacted, namely electromagnet produces magnet and attracts the upper end of claw is inwardly bounced back around pin joint, and the other end of claw expands outwardly around pin joint, the inner space of the column grasping part that multiple claw is formed increases, namely ensure that claw can to the foreign material of the whole inside of oil well, such as crushed stone, wire rope, cable rope etc. are cleared up; When the bottom of claw is placed in shaft bottom, the electric current passed in electromagnet changes, the attraction state of electromagnet to magnet is made to become repulsion state, the upper end of claw starts away from electromagnet, its other end is then close to support column axis place place, and then the grasping part making the foreign material etc. in oil well enter multiple claw to be formed, when the ends contact of the inwall of claw and spacing hole, claw stops continuing to move, and prevents multiple claw from excessively moving each other and causing impaired.
The inner wall at end of described claw is fixed with latch.For strengthening the salvaging effect of claw to foreign material further, claw being provided with latch, preventing foreign material from dropping in salvaging uphill process.
Multiple described claw ringwise and array distribution on support bar.Multiple claw annular array is hinged on support bar, makes multiple claw form a cone shape grasping part, to ensure that claw is cleared up completely to the foreign material in oil well.
Also comprise connector, described connector is fixed on the top of support column and coordinates with the lifting gear of outside.Connector is used for being connected with the lifting gear of outside, and this lifting gear can be steel cable or draw bar, is shifted out together in oil well by related for salvaging structure foreign material by steel cable or the lifting of draw bar.
The utility model compared with prior art, has following advantage and beneficial effect:
1, support column is slowly put into oil well by the utility model, start power supply simultaneously, magnet on electromagnet and claw is interacted, namely electromagnet produces magnet and attracts the upper end of claw is inwardly bounced back around pin joint, and the other end of claw expands outwardly around pin joint, the inner space of the column grasping part that multiple claw is formed increases, and namely ensure that claw can to the foreign material of the whole inside of oil well, such as crushed stone, wire rope, cable rope etc. are cleared up;
2, the utility model is strengthen the salvaging effect of claw to foreign material further, and claw is provided with latch, prevents foreign material from dropping in salvaging uphill process;
3, the multiple claw annular array of the utility model is hinged on support bar, makes multiple claw form a cone shape grasping part, to ensure that claw is cleared up completely to the foreign material in oil well.

Detailed description of the invention
Clearly understand for making the purpose of this utility model, technical scheme and advantage, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, exemplary embodiment of the present utility model and explanation thereof are only for explaining the utility model, and conduct is not to restriction of the present utility model.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment comprises the support column 2 of inner hollow, the sidewall of described support column 2 has multiple rectangular opening 6, the bottom of support column 2 has multiple spacing hole 8 interconnective with rectangular opening 6, the hollow cavity internal fixtion of support column 2 has the support bar 7 of taper, is connected with multiple claw 3 at the sidewall upper hinge of described support bar 7; Also comprise the electromagnet 95 being fixed on support bar 7 top, electromagnet 95 is connected with external power source by wire, and on the side of support bar 7, be provided with the magnet 9 matched with electromagnet 95 at claw 3; The inner wall at end of described claw 3 is fixed with latch 4; Multiple described claw 3 ringwise and array distribution on support bar 7; Also comprise connector 1, described connector 1 is fixed on the top of support column 2 and coordinates with the lifting gear of outside.
During utility model works, rectangular opening 6 and spacing hole 8 form the L shape activity interval of claw 3 on support bar 7, support column 2 is slowly put into oil well, start power supply simultaneously, electromagnet 95 is interacted with the magnet on claw 3, namely electromagnet 95 pairs of magnet 9 produce and attract the upper end of claw 3 is inwardly bounced back around pin joint, and the other end of claw 3 expands outwardly around pin joint, the inner space of the column grasping part that multiple claw 3 is formed increases, namely ensure that claw 3 can to the foreign material of the whole inside of oil well, such as crushed stone, wire rope, cable rope etc. is cleared up, when the bottom of claw 3 is placed in shaft bottom, the electric current passed in electromagnet 95 changes, the attraction state of electromagnet 95 pairs of magnet 9 is made to become repulsion state, the upper end of claw 3 starts away from electromagnet 95, its other end is then close to support column 2 axis place place, and then make the foreign material etc. in oil well enter the grasping part of multiple claw 3 formation, when the ends contact of the inwall of claw 3 and spacing hole 8, claw 3 stops continuing to move, and prevents multiple claw 3 excessively mobile each other and causes impaired, for strengthening the salvaging effect of claw 3 pairs of foreign material further, claw 3 being provided with latch 4, preventing foreign material from dropping in salvaging uphill process, multiple claw 3 annular array is hinged on support bar 7, makes multiple claw 3 form a cone shape grasping part, to ensure that the foreign material in claw 3 pairs of oil wells are cleared up completely.
Further, connector 1 is for being connected with the lifting gear of outside, and this lifting gear can be steel cable or draw bar, is shifted out together in oil well by related for salvaging structure foreign material by steel cable or the lifting of draw bar.
Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only detailed description of the invention of the present utility model; and be not used in restriction protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
