The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, compound anti-block apparatus comprises and establishing in the threaded top connection 1 that the top connection lower end links to each other with tube connector 3, and the upper end of top connection then links to each other with the oil pipe of oil well pump bottom; Top connection and tube connector connecting place are provided with steel ball seat 2, this steel ball seat top is provided with a steel ball 14, the middle part of tube connector is provided with boss, and the both sides of described boss are respectively equipped with a diameter changing device 4, described tube connector lower end is connected with vibrating tube 9 by adapter sleeve 8, and also be provided with valve seat 6 in tube connector lower end and vibrating tube junction, this valve seat is provided with the valve gap 7 that is connected with valve seat by straight pin 13; Be socketed with vibrating reed group 12 on the described vibrating tube, this vibrating tube lower end is provided with for the lower thread bush 10 that connects end connector 11.
Above-mentioned diameter changing device comprises six curved plates and 12 fixed blocks, described curved plate is provided with pin shaft hole 17, fixed head is provided with slideway 18, and by bearing pin two fixed blocks are installed between per two curved plates, all curved plates and fixed block consist of a circumference, and six Compress Springs 5 and corresponding spring support are housed in the circumference.
When the utility model is worked, six curved plates of diameter changing device are under the active force of six roots of sensation Compress Spring, the inwall of being close to sleeve pipe, because diameter changing device is under the active force of Compress Spring, all the time tightly be attached to internal surface of sleeve pipe, so diameter changing device can block the ring shaped oil passage between oil pipe and the sleeve pipe all the time, because the compressible Compress Spring corresponding with it of curved plate, make the variable diameter of diameter changing device, therefore the utility model is in underground work, can according to the internal diameter of pit shaft, automatically regulate its external diameter.
Described curved plate just is considered as " king " font, and the height of the horizontal piece 15 in middle part is 5～6 times of the horizontal piece 16 in end, and horizontal piece center, middle part is provided with a through hole that is slidingly connected with spring support, be respectively equipped with two pin shaft holes on described two horizontal pieces in end, be positioned at the two ends of this horizontal piece, the pin shaft hole relative position of the horizontal piece in middle part and the horizontal piece in end is provided with pin shaft hole equally, and shape size is identical; Described fixed block is cuboid, and the cuboid two ends are respectively equipped with a slideway.Curved plate and fixed block are installed together, and curved plate can along the circumferential direction be free to slide in slideway, and the slideway limit is sealed simultaneously, and curved plate can not break away from slideway.
In order to guarantee sufficient oil mass, so be provided with a plurality of sieve apertures in vibrating tube.
Described vibrating reed group is by 18 millimeters thick, 27 millimeters thick, 26 millimeters thick, 25 millimeters thick, 24 millimeters thick, 13 millimeters thick coil component spring steel disc forms, vibrating reed group two ends also are provided with respectively a cylindrical piece, and all parts of all vibrating reed groups are solidified as a whole, and this whole sheet group is socketed on the vibrating tube outer wall, can be free to slide in vibrating tube.
The course of work:
When the oil pumper upstroke, the fluid column load transfer is to sucker rod in the oil pipe, the oil pipe elastic shrinkage moves upward, driving the utility model moves upward together, at this moment, because the vibrating reed group is to be socketed on the vibrating tube outer wall, the amplitude that the vibrating reed group moves upward is less, the lower contact of the utility model lower end must be clashed into mutually with the vibrating reed group, just sends sound wave and imports the stratum into, then, the utility model continues to move upward, meanwhile, steel ball is blocked steel seat mouth, the ring shaped oil passage between diameter changing device shutoff oil pipe and sleeve pipe, steel ball below liquid can only be moved upward together along with the utility model, cause the steel ball lower zone to form negative pressuren zone, this motion produces again the negative pressure hydraulic ripple of a moment to the oil flow channel in the stratum, namely oil reservoir is produced a suction force.During the utility model stop motion, namely arrive top dead centre, each pressure reaches again equilibrium state.
When oil pumper undershoot process, fluid column load all acts on the oil pipe again in the oil pipe, the oil pipe elastic elongation moves downward, driving the utility model moves downward together, at this moment, because the vibrating reed group is to be socketed on the vibrating tube outer wall, the amplitude that the vibrating reed group moves downward is less, the adapter sleeve of diameter changing device of the present utility model lower end must clash into mutually with the vibrating reed group, just send sound wave and import the stratum into, then the utility model continues to move downward, meanwhile, valve gap is closed, diameter changing device has still blocked the ring shaped oil passage between oil pipe and the sleeve pipe, and valve gap below liquid can only be moved down together along with the utility model, causes the valve gap lower zone to form the higher-pressure region, this produces an instantaneous pressure hydrodynamic wave (H wave) to the oil flow channel in the stratum again with motion, namely oil reservoir is produced an extruding force.During the utility model stop motion, namely arrive lower dead center, each pressure reaches again equilibrium state, so far, finishes the one-period motion.
According to above-described embodiment, just can realize well the utility model.
