Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
nullAs shown in Figures 1 to 6，One pumps out storage type logging special Fuse Type release，Including salvaging shell 1，Its top is provided with cable connector 2，Bottom is provided with instrument joint 3，Salvaging inner shell 4 it is provided with in salvaging shell 1、Baffle ring 5、Three tapered sleeves 6、Breaking device 7 and fusing release device 8，Salvage inner shell 4、Breaking device 7 and fusing release device 8 are sequentially connected with，Described three tapered sleeve 6 one end connect cable connector 2，The other end stretches in salvaging inner shell 4，Salvage and on inner shell 4, offer hole, location，Three tapered sleeve 6 outer walls are correspondingly provided with locating slot，Steel ball 9 is placed in hole, location，Salvage and be provided with baffle ring 5 between shell 1 inwall and salvaging inner shell 4 outer wall，This baffle ring 5 by spacing for steel ball 9 location hole and locating slot in，It is characterized in that: described baffle ring 5 is socketed in salvaging inner shell 4 outer wall，And it is connected fixing by alignment pin 10 with salvaging shell 1.
See Fig. 3, breaking device 7 includes left part 71, limited screw 73, right part 72 and chest-developing bar 74, left part 71 one end is connected with salvaging inner shell 4, the other end is socketed in right part 72 one end, the other end of right part 72 is connected with fusing release device 8, and threadeding with salvaging inner shell 4 in chest-developing bar 74 one end, the other end stretches in right part 72 through left part 71, at chest-developing bar 74 outer socket limited screw 73, limited screw 73 by spacing for chest-developing bar 74 in right part 72.The stretching resistance of described chest-developing bar 74 is 1.5 tons.
See Fig. 3, described fusing release device 8 includes disengaging pawl 81, housing 82, brake bar 83, fuse 84 and union joint 85, disengaging pawl 81 one end is fastened on the right part 72 of breaking device 7, the other end coordinates in housing 82, union joint 85 one end is connected with housing 82, the other end is connected with instrument joint 3, brake bar 83 one end is reducing round bar, it inserts in disengaging pawl 81, the other end is connected with union joint 85 by fuse 84, is provided with compression spring 86 between disengaging pawl 81 end and brake bar 83.Being provided with flange along brake bar 83 outer wall circumference, compression spring 86 is arranged between disengaging pawl 81 and flange.
See Fig. 4 to Fig. 6, described fuse 84 includes fixture block 84-1, copper ring 84-2 and heating rod 84-3, four pieces of fixture block 84-1 splits are cylindrical main body, there is pyramidal pits 84-4 at this center, main body two ends, axially have the groove installing heating rod 84-3 along main body, heating rod 84-3 is arranged in this groove, and four pieces of fixture block 84-1 and heating rod 84-3 are coated togather by copper ring 84-2, copper ring 84-2 is fixed by scolding tin 84-5 at two ends, and this scolding tin 84-5 is close to heating rod 84-3.
After this Fuse Type release installs, compression spring 86 makes the outer wall that brake bar 83 reducing round bar end top external diameter is bigger be close to inside disengaging pawl 81, causes disengaging pawl 81 to be tightly stuck in the mating groove in housing 82 so that disengaging pawl 81 is tightly connected with housing 82.Baffle ring 5 inwall blocks the steel ball 9 in three tapered sleeve 6 locating slots so that three tapered sleeves 6 are connected on release.Scolding tin 84-5 is caused to melt by being heated for the heating rod 84-3 within electric fuse 84, so that copper ring 84-2 unclamps, fixture block 84-1 dispersion is unclamped unfettered, thus terminates the constraint to brake bar 83, compression spring 86 promotes brake bar 83 to move down, and then terminates the space constraint to disengaging pawl 81.Extra increasing lifts external force, the force-applied deformation of disengaging pawl 81, separate so that three tapered sleeves 6 are inconjunction with disengaging pawl 81 with fusing release device 8, the steel ball 9 that script is blocked restriction three tapered sleeves 6 by baffle ring 5 enters the position that salvaging shell 1 internal diameter is bigger, steel ball 9 departs from three tapered sleeve 6 locating slots and no longer blocks three tapered sleeves 6, thus related three tapered sleeves 6 of cable separate with salvaging shell 1.Instrument is released, and proposes cable, and pull out of hole well logging.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
