Description
Technical field
The utility model belongs to underground work fishing device technical field, relates to a kind of underground work fishing socket.
Background technology
Rig tool, bias-wearing-proof apparatus of pumping rod, the sheet that packing element fragment equal-volume is less, block smallclothes class junk is often there will be in underground work process; major diameter instrument (drift size gauge tool, packer etc.) enters under will be caused to be difficult to; current conventional tool is difficult to realize salvaging; be embodied in: current fishing socket is when salvaging sheet, the block smallclothes class junk of small volume; easily cause the landing of the sheet of small volume, block smallclothes class junk, thus the failure of fishing can be caused.
Summary of the invention
For the problems referred to above, the underground work fishing socket that the technical problems to be solved in the utility model is to provide a kind ofly effectively can realize the sheet to down-hole small volume, block smallclothes class junk is salvaged.
Underground work fishing socket of the present utility model, comprise lower end with the cylindrical shell of opening and connector, it also comprises a piggyback pod, lower end and the cylindrical shell of described piggyback pod are spirally connected, the upper surface of described connector and piggyback pod is fixed, described piggyback pod is internally connected with motor, described inner barrel is provided with power transmission shaft, described power transmission shaft is connected by shaft coupling with the rotating shaft of motor, described cylinder inboard wall is provided with back-up ring, collecting bin is formed between described back-up ring and cylinder inboard wall, the cylindrical shell of described collecting bin both sides is provided with screen pack, gap is left between described power transmission shaft and back-up ring, the power transmission shaft of described back-up ring bottom is provided with several blades, seal receptacle is provided with between the rotating shaft of described motor and cylinder inboard wall.
Underground work fishing socket of the present utility model, wherein, described seal receptacle is pressed on cylindrical shell by piggyback pod.
Underground work fishing socket of the present utility model, wherein, described back-up ring is " ⊥ " shape structure of middle part with through hole.
The utility model beneficial effect: during use, by connector, the utility model is connected with fishing string and G.I.H, during work, the rotation of power transmission shaft and blade is driven by the rotation of motor, when blade rotates, with the sheet of small volume, the well liquid of block smallclothes class junk to be pumped in cylindrical shell and to enter into collecting bin by the gap between power transmission shaft and back-up ring, due to the cylindrical shell of both sides being provided with screen pack, the sheet of the small volume in well liquid, block smallclothes class junk can be collected in collecting bin, the sheet of filtering small volume, well liquid after block smallclothes class junk is then back in well again through after screen pack, the utility model effectively achieves the salvaging of the sheet to down-hole small volume, block smallclothes class junk, improves the success rate of the sheet to down-hole small volume, block smallclothes class fishing junk, ensure that normally carrying out of trouble of lost tool in hole salvage.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
Underground work fishing socket as shown in Figure 1, comprise lower end with the cylindrical shell 1 of opening 11 and connector 2, it also comprises a piggyback pod 3, lower end and the cylindrical shell 1 of described piggyback pod 3 are spirally connected, described connector 2 is fixed with the upper surface of piggyback pod 3, described piggyback pod 3 is internally connected with motor 4, described cylindrical shell 1 inside is provided with power transmission shaft 5, described power transmission shaft 5 is connected by shaft coupling 6 with the rotating shaft of motor 4, described cylindrical shell 1 inwall is provided with back-up ring 7, collecting bin 8 is formed between described back-up ring 7 and cylindrical shell 1 inwall, the cylindrical shell 1 of described collecting bin 8 both sides is provided with screen pack 9, gap is left between described power transmission shaft 5 and back-up ring 7, the power transmission shaft 5 of described back-up ring 7 bottom is provided with several blades 51, seal receptacle 10 is provided with between the rotating shaft of described motor 4 and cylindrical shell 1 inwall, described seal receptacle 10 is pressed on cylindrical shell 1 by piggyback pod 3, described back-up ring 7 is " ⊥ " shape structure of middle part with through hole.
During use, by connector, the utility model is connected with fishing string and G.I.H, during work, the rotation of power transmission shaft and blade is driven by the rotation of motor, when blade rotates, with the sheet of small volume, the well liquid of block smallclothes class junk to be pumped in cylindrical shell and to enter into collecting bin by the gap between power transmission shaft and back-up ring, due to the cylindrical shell of both sides being provided with screen pack, the sheet of the small volume in well liquid, block smallclothes class junk can be collected in collecting bin, the sheet of filtering small volume, well liquid after block smallclothes class junk is then back in well again through after screen pack.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
