Detailed description of the invention
Below in conjunction with the accompanying drawings the specific embodiment in the present invention is described in further detail.
As shown in figures 1-8, a kind of multifrequency lever formula vibrator of the present invention, it is characterised in that: it is made up of internal lever system and outer, stationary fixed system,
Described inside lever system includes connecing 12 under center-pole 2, center-pole top connection 1 and center-pole, and described center-pole 2 one end is connected with center-pole top connection 1, and the other end is connected with center-pole lower contact 12；Described center-pole 2 is equipped with female adapter 2-1 by two ends and intermediate bar is formed, and described intermediate bar is that outer surface is distributed the multistage intermediate bar being made up of the annular round and smooth step 2-3 vertical with axis for ripple 2-2 of different pitch；
Described outer, stationary fixed system is by central tube 3, flat spring 4, guiding rib 5, righting rib 6, helical spring 8, ball seat 10 and steel ball 11 are constituted, central tube 3 and flat spring 4 are successively set on the outer middle side part of center-pole 2, described central tube 3 and flat spring 4 have multiple helical spring hole, helical spring 8 is arranged in the helical spring hole of flat spring 4, righting rib with helical spring hole is sleeved on the outside of helical spring, central tube and flat spring also have bolt positioning hole, described central tube, flat spring and righting rib are by guiding rib 5 and the fixing connection of bolt 9；
It is provided with ball seat 10 at described central tube 3 two ends, steel ball 11 is placed in ball seat 10, and be connected with the multistage intermediate bar rolling of center-pole 2, through hole is set in the bottom of ball seat 1, the two ends of flat spring 4 are inserted in the through hole of two ball seats respectively, make internal lever system move up and down in outside fixed static system.
Further, the multistage intermediate bar described in this is three sections, and every section of pitch ripple size is for successively decreasing successively or ripple size is for being incremented by successively or pitch ripple size is that two is little broad in the middle or pitch ripple size is that big centre, two is little.In figure, 5-Fig. 6 shows that every section of pitch ripple size is the structural representation successively decreased successively.Owing to the intermediate bar of the center-pole of internal lever system is that the round and smooth step of annular that outer surface is distributed the ripple by different pitch vertical with axis forms, the steel ball on ball seat on central tube two ends is close to center-pole, on the outer surface of center-pole during linear motion, it is rugged movement locus for steel ball, owing to flat spring inserts in ball seat, therefore steel ball has driven flat spring two ends to make amplitude of oscillation motion, produce vibrations, simultaneously because flat spring has certain rigidity, steel ball is applied certain elastic force, so the vibrations produced have certain energy and different frequencies, form multifrequency lever formula vibrator.
Further, the outer surface of described righting rib 6 is that the face of cylinder, inner surface have helical spring groove and dowel hole, and in described dowel hole, it is provided with alignment pin 7, it is therefore an objective to make helical spring 8 can be accurately positioned in helical spring hole and the helical spring groove of flat spring 4.
Flat spring 4 described further is three, and guiding rib 5 is six, and righting rib 6 isThreeIndividual, helical spring 8 is 12, and bolt is interior hexagonal totally six, and ball seat 10 is six, and steel ball 11 is six.
The principle of the present invention is:
During actual application, multifrequency lever formula vibrator is arranged near the oil reservoir of oil well, the outer surface of the righting rib 6 that it is outside and is fixed on the inwall of oil well casing in inner support by helical spring 8, the upper external screw thread of center-pole top connection 1 can directly be connected with the sucker rod on top, sucker rod is continuously connected to the oil pumper on ground, the lower end internal thread of center-pole lower contact 12 can be connected with the sucker rod of bottom, when the sucker rod of oil well pumps with ground oil pumper, center-pole 2 will be followed and is synchronized with the movement, steel ball 11 and flat spring 4 is driven to shake, also transmit vibrations to righting rib 6 simultaneously, it is delivered to the oil reservoir near oil well casing tube wall and jacket exterior again by righting rib 6, play the effect of oil layer unblocking volume increase.
The multifrequency lever formula vibrator of the present invention can multiple be used in series, and according to quantity and the thickness of oil reservoir of oil well oil reservoir, the quantity of flexible configuration bar power multifrequency lever formula vibrator, can obtain more preferable effect of increasing production.
