Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, the anti-blocking mechanism of the bailing pump comprises an upper ball head 1 and a lower ball head 10, wherein the upper portion of the upper ball head 1 is the ball head, the bottom of the upper ball head is connected with a fluid 2 through external threads, the outer portion of the upper flow body 2 is connected with a barrel 5 through an inner snap spring 16, the side walls of the upper end and the lower end of the barrel 5 are respectively provided with an upper through hole 15 and a lower through hole 14, the upper through hole 15 and the lower through hole 14 are axially long round holes uniformly distributed along the circumferential direction, vertical through holes are formed in the upper flow body 2 and the lower flow body 11, and a stopper 7 is fixed on the outer wall of the barrel 5 below the upper through hole 15 through a pin 6. The bottom of the upper ball head 1 is connected with a bearing bolt 4 through a connecting screw rod 3, a lower passing fluid 11 is arranged between the outer side of the bottom of the bearing bolt 4 and the cylinder 5, and the lower passing fluid 11 is connected to the inner wall of the cylinder 5 through threads. The outer side of the middle part of the bearing bolt 4 is provided with a boss, the lower part of the boss is fixed with a copper sleeve 12, and the copper sleeve 12 is made of red copper. The outside of barrel 5 is equipped with packing element 13, stopper 7 is located packing element 13 upper end, can keep off packing element 13 and drop on the one hand, and on the other hand can accelerate to change the packing element speed after dismantling stopper 7.
The lower end of the bearing bolt 4 is connected with a lower ball head 10, the upper portion of the lower ball head 10 is connected with a tray seat 9, a tray 8 is arranged on the upper portion of the tray seat 9, the tray 8 is seated on the tray seat 9 through a slope, a sealing rubber ring is omitted from the tray seat 9, the tray is enabled to be rigidly sealed, the use condition in winter is achieved, and the rubber cylinder 13 and the tray 8 are clamped together through steps.
After the bailing car arrives at a well site, the upper ball head 1 is hung on the bailing car, the lower ball head 10 is connected with a heavy hammer, the bailing car is manually righted and placed into a shaft, a steel wire rope of the bailing car descends, the speed is reduced after the steel wire rope contacts the underground liquid level, and therefore the steel wire rope is prevented from knotting. Due to the resistance of an oil-water medium, the tray 8 and the rubber barrel 13 move upwards relative to the barrel 5 and stop at the position of the limiting stopper 7, at the moment, the lower through hole 14 on the barrel 5 is exposed, a liquid medium enters from the lower through hole 14 and flows out from the upper through hole 15 and the upper overflowing body 2 at the upper end of the barrel 5 (part of the liquid medium flows out through the first overflowing body 2, so that the descending speed of the bailing pump is higher than that of an old-fashioned bailing pump), the bailing pump continues to descend under the action of a heavy hammer, the descending distance is controlled through a stroke meter of the bailing vehicle, and the descending is stopped after the specified depth is; and then the bailing vehicle moves upwards, at the moment, the rubber sleeve 13 and the tray 8 move downwards relative to the cylinder body 5 under the action of liquid resistance and keep relatively static after contacting with the tray seat 9, the tray 8 and the tray seat 9 are firmly pressed due to the pressure action of the liquid column, meanwhile, pressure difference is formed between the upper end and the lower end of the rubber sleeve 13, the rubber sleeve 13 is forced to expand and is tightly attached to and sealed with the well wall, and liquid medium reaches the well mouth and enters the tank car through a connecting pipeline.
If the bailing pump meets jamming caused by well wall deformation or shaft bottom sand production in the process of going upwards, the lifting power can be properly increased but is far smaller than the breaking tension of a steel wire rope, at the moment, the connecting bolt 3 is broken, when the bearing bolt 4 slides downwards to pass through the fluid 11, the copper sleeve 12 outside the bearing bolt 4 is blocked by the lower passing fluid 11 to stop, because the impact force is larger in the sliding process, the impact force can be relieved by the impact deformation of the copper sleeve 12, the impact force is delayed by utilizing the plastic deformation of copper metal, other components are prevented from falling, and the downward movement of the rubber cylinder 13, the tray 8 and the lower part also stops along with the bearing bolt 4. The lifting force is properly increased, the rubber sleeve 13 can deform and pass through the blocking point when encountering the blocking point due to good elasticity and deformability of the rubber sleeve, the tray 8 is difficult to pass through the blocking point when encountering the blocking point due to large overall dimension, the inner hole of the tray is large, and the diameter of the vertical bearing bolt 4 is small, so that the tray can pass through the blocking point by translation and side turning when encountering the blocking point, and other parts can pass through the blocking point smoothly due to small overall dimension.
