Background
In the oil extraction operation process, the lower end of the oil well pump is provided with a fixed valve assembly, and crude oil extraction is completed through opening and closing of a valve ball and a valve seat in the fixed valve assembly. In the pump inspection operation process of the oil production well, oil and water in the oil pipe can be brought to the ground, so that the ground environment is polluted. Although the tubular pump is connected between the lower end of the pump cylinder and the fixed valve of the pump by installing the oil drain when the tubular pump is started, the commonly used oil drain comprises a shear type oil drain and an oil pipe anchor type oil drain, but because the installation position of the oil drain is a certain distance from the tubular pump, the oil and water in the distance between the tubular pump and the oil drain cannot be drained, and the oil and water can still be brought to the ground to pollute the ground environment. In addition, there is a problem in that the slim hole drain cannot be mounted to the pump barrel and the downhole drain having a low liquid level does not function, thereby causing failure in normal drainage.
Chinese patent CN106286245A discloses an oil well pump for opening valve ball and discharging liquid, which adopts the method that an assembly is directly installed in the oil well pump, when a piston is needed to discharge liquid in the pump, an articulated ejector rod is pressed down by the piston, the articulated ejector rod lengthens a top-driving ball shifting plate, the ball shifting plate opens a fixed valve ball, a top ball cylinder on the piston simultaneously pushes up a downstream valve ball, the downstream valve ball pushes up a top ball rod, and the top ball rod pushes up an upstream valve ball. Thereby completing the drainage of the liquid above the valve ball into the well. However, the above-mentioned patent has problems that it is an improvement to the oil pump, and is not suitable for all oil pumps, and the improved oil pump has a complex structure, and the movable joint ejector rod and the ball shifting plate are easy to fail, once the movable joint ejector rod or the ball shifting plate fails, the whole oil pump cannot be used, and in general, the oil pump is located under the ground very far from the ground, and the installation and salvaging of the oil pump are all very complex works, so that the use effect is poor for the oil pump extremely easy to fail.

The patent realizes that normal oil drainage of an oil well can be realized through the valve cover and the prizing valve ball. Thus overcoming the defects that the prior oil drainage device is easy to fail, the well with small well hole and lower liquid level can not drain oil normally. However, the above patent has the disadvantage that the striker is not easy to automatically enter the gap between the valve ball and the valve seat when contacting the valve ball because the striker is arranged at the center of the cylinder, so that the valve ball needs to be opened by using the poking device for a long time, and the efficiency is low.

Further, referring to fig. 2, the striker assembly 11 includes a striker 111 and a water dividing head 112. Wherein the central axis of the striker 111 of the striker assembly 11 is disposed offset from the central axis of the barrel 10. That is, the striker 111 is disposed at the bottom end of the water dividing head 112 and is disposed offset from the center axis of the cylinder 10.

Further, a water dividing head 112 is provided at the bottom end of the cylinder 10. Preferably, a surface of the water dividing head 112 connected to the striker 111 is provided as an inclined surface. Preferably, the striker 111 is disposed between the bottommost end of the inclined surface of the water dividing head 112 and the central axis of the water dividing head 112. According to the invention, the firing pin is arranged at the position deviating from the central axis of the cylinder, so that the gravity center of the whole device is offset laterally, and the offset towards the side wall of the pump cylinder in the descending process of the valve ball pulling device is facilitated. In addition, the bottom surface of the water distributing head 112 is provided with an inclined surface structure, and in the descending process of the device, the pressure of oil liquid on the inclined surface is vertical to the direction of the inclined surface, and as the inclined surface and the horizontal plane have a certain included angle, the pressure of the oil liquid on the inclined surface of the water distributing head can be upwards non-vertically, so that the whole device can further deviate to the side wall of the pump barrel in the descending process. Because the opening above the valve cover is positioned at the position of the valve cover, which is close to the side wall of the pump cylinder, the valve ball pulling-out device is beneficial to easily entering the opening above the valve cover.

Preferably, the longitudinal direction of the paddles 42 is non-parallel to the central axis of the entire device or cylinder, thereby causing the device to exert pressure in the circumferential direction and cause the device to spin during descent.
Further, a speed reducing head 43 is provided at the lower end of the fixed column of the paddle 42. Preferably, the speed reducing head 43 may be of a cylindrical structure.

For example: taking a 57# tubular pump as an example, the inner diameter of a pump cylinder is phi 57mm, and the outer diameter of a speed reducing head can be phi 55mm. Therefore, after the device is put into the oil pipe, the speed of the whole device in the descending process is continuously increased under the action of gravity acceleration, after the device enters the pump barrel of the tubular pump, the oil liquid flow with the same volume as the device can be discharged upwards through a gap between the speed reducing head 43 and the pump barrel wall, the movement direction of liquid discharged upwards is opposite to that of the descending valve ball poking device, the descending speed of the valve ball poking device can be reduced through the obstruction of the shoulder of the speed reducing head to the oil liquid moving upwards, the valve ball poking device is enabled to be kept stably descending integrally, the descending speed of the poking device is prevented from being too fast, and the damage of excessive impact to the device is slowed down.
Further, the cylinder 10 is connected to the bottom end of the speed reducing head 43. Wherein a drive assembly 13 is provided in the upper half of the cylinder 10.
