[0021] Example: Refer to Figure 1-2An oil well downhole operation fishing tool shown in the figure includes a fishing cylinder body 1. On the outer side wall of the fishing cylinder body 1, an electric push rod 2 is fixedly installed. There are several electric push rods 2, which are evenly spaced around the axis of the fishing cylinder body 1. At the end of the output end of the electric push rod 2, a roller 3 is rotatably installed. Inside the fishing cylinder body 1, there is a garbage storage cavity 4. Near the top of the fishing cylinder body 1, there are several liquid inlets 5, which are evenly spaced around the axis of the fishing cylinder body 1. At the bottom inside of the fishing cylinder body 1, a drainage pump 6 is fixedly installed. The input end of the drainage pump 6 leads into the garbage storage cavity 4, and the output end of the drainage pump 6 leads to the outside of the fishing cylinder body 1. At the top of the fishing cylinder body 1, a cover plate 13 is installed. At the center of the cover plate 13, a lifting ring 12 fixedly connected to it is installed. When in use, the device is lowered into the oil well by fixing it with a rope on the lifting ring. When lowering, each electric push rod is turned on so that its roller abuts against the inner wall of the oil well, and thus it can be stably lowered by rolling. When it is lowered to the liquid inlet, oil and impurities start to enter. The impurities remain inside the garbage storage cavity, and the drainage pump discharges the oil that has entered inside.

[0022] With the above structure: On one side of the fishing cylinder body 1, there is a material taking door 11. The top of the material taking door 11 is hinged to the fishing cylinder body 1, and the bottom of the material taking door 11 is bolted to the fishing cylinder body 1. Opening the material taking door can take out the internal garbage.

[0023] With the above structure: On the inner wall of the fishing cylinder body 1, several fan-shaped baffles 10 are fixedly installed. Each baffle 10 is alternately distributed in the vertical direction. The baffle 10 is arranged in an inclined downward manner inside the fishing cylinder body 1. The baffle 10 is located below the liquid inlet 5. Such alternating baffles can prevent the discharged garbage from being discharged.

[0024] With the above structure: At the bottom of the fishing cylinder body 1, a waterproof power supply box 8 is fixedly installed. Inside the power supply box 8, a rechargeable power supply 9 is fixedly installed. The power supply 9 is electrically connected to the electric push rod 2 and the drainage pump 6.

[0025] With the above structure: A retaining net 7 is fixedly installed at the input end of the drainage pump 6, which can prevent the drainage pump from being blocked by garbage and also prevent the garbage from being discharged.

[0026] With the above structure: On the front side of the power supply box 8, there is a waterproof charging port.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
