Tapered end (1) upper end face is provided with scale numeral (14).
One side of lock collar (2) is fixed on the top of lock frame (4) through screw (10), and the surface of lock collar (2) is provided with scale numeral (16), and to be provided with scale numeral (14) corresponding with tapered end (1) surface.
Go up symmetry in locking plate (6), (7) and have the hole; Locking plate (8) is gone up symmetry and is had two groups of holes; The plush copper (15) that symmetry is arranged on the edge of locking plate (6), (7) and (8); With the engagement on lock frame (4) sidewall, the hole of locking plate (6), (7) and (8) is corresponding each other, and the hold-down screw (13) that in the hole of correspondence, misplaces.
Inside edge one side of partition (5) is provided with plush copper (17).
The described a kind of production tree draining anti-theft device of the utility model; This device at first combines oil field site plant situation; Making full use of on the basis of existing equipment, through little input, design production tree draining anti-theft device; Open-air production tree bypass valve drain tap is effectively controlled through solid and reliable anti-theft device; The assurance anti-theft device can't be opened with being connected from the outside of drain tap, and in the anti-theft device keyhole was housed, and has only password and the two combination of key of unique anti-theft device could be opened drain tap.Through nearly 1 year in the oil recovery factory field trial of nearly 40 mouthfuls of wells, its effect has reached purpose of design, has realized having stopped open-air generation from well head production tree stolen phenomenon, guarantees the ordinary production in oil field, the economic loss that reduces the oil field with reduce security risk.

The specific embodiment
Further describe and provide embodiment below in conjunction with width of cloth figure
The described a kind of production tree draining anti-theft device of the utility model, this device is made up of lock frame and lock core, and lock core is made up of tapered end, lock collar, partition, locking plate, cottor pin, nut, spacer ring and plug; Tapered end 1 is a T-shape, and tapered end 1 upper end face is provided with scale numeral 14, on tapered end 1 T-shape, is with tapered end sleeve pipe 3; One side of lock collar 2 is fixed on the top of lock frame 4 through screw 10, and the surface of lock collar 2 is provided with scale numeral 16, and to be provided with scale numeral 14 corresponding with tapered end 1 surface; On tapered end sleeve pipe 3, be with locking plate 6,7 and 8 respectively, symmetry has the hole on locking plate 6,7, and symmetry has two groups of holes on the locking plate 8; The plush copper 15 that symmetry is arranged on locking plate 6,7 and 8 the edge, with the engagement on lock frame 4 sidewalls, locking plate 6,7 and 8 hole are corresponding each other; And in the hole of correspondence dislocation hold-down screw 13, be respectively equipped with partition 5 between tapered end sleeve pipe 3 and the three layers of locking plate 6,7 and 8, inside edge one side of partition 5 is provided with plush copper 17; When three layers of locking plate 6,7 and 8 and after partition 5 is inserted in tapered end sleeve pipe 3 respectively, cottor pin 9 is inserted in the hole of tapered ends 1 bottom, the screw thread that screws in the lower end of tapered end 1 with nut is again fixed locking plate; The bottom of lock frame 4 is provided with spacer ring 11; Plug 12 is connected with spacer ring 11, on the sidewall on lock frame 4 tops, has groove, and lock core is fixed in the lock frame 4.
During use, plug 12 is screwed into the clip short circuit of oil well casing gate or pins the gate leading screw by specialized nut, when needs are opened anti-theft device; By 8 rotations of tapered end 1 rotating band moving lock sheet, when rotating, the screw 13 that the screw 13 on the locking plate 8 is run on the locking plate 7 drives locking plate 7 rotations again; When Rotate 180 was spent, the screw 13 on the locking plate 7 was run into the screw 13 on the locking plate 6, drove locking plate 6 rotations again; When plush copper is consistent with the groove on the lock frame 4 on rotating to locking plate 6, stop the rotation, in rotation in the opposite direction; At this moment still driving locking plate 8 rotations by tapered end 1 has the screw 13 on the locking plate 8 to run into the screw 13 on the locking plate 7 again, drives locking plate 7 rotations, when plush copper on the locking plate 7 is consistent with the groove on the lock frame 4; Stop operating, drive locking plate 8 by tapered end 1 again and rotate in the opposite direction, when the plush copper on the locking plate 8 is consistent with the groove on the lock frame 4; The lock core part can be taken out, with special spanner dismounting plug 12, anti-theft device can be opened again.Each rotation all is to lean on the scale on the tapered end 1 decide benchmark with the scale on the lock collar 2, and the time spent is covered up lock collar 2 taking-ups, and anti-theft device has not just been opened, and when needs are opened, lock collar 2 usefulness screws 10 is fixed on to lock on the frame 4 could confirms benchmark.Have only in this anti-theft device to be fixed on the place, location to password contrast key and just can to make sign, could open anti-theft device, effectively prevent the generation of stolen incident according to the password of setting.
