In the process of oil field development and operation, the oil pipeline needs to be cleaned periodically. Cleaning and unclogging of a pipeline is typically accomplished by introducing a fluid into the pipeline to create pressure.
However, due to factors such as geology and approach rivers, the direction of the oil pipeline may change, which may cause the oil pipeline to have an excessively large curve. When a common pipe cleaner passes through a bend, blockage is easy to occur. When the pipe cleaner is not seriously blocked, the pressure of fluid in the pipeline is increased usually so as to push the pipe cleaner to smoothly pass through the bent pipe, but the pipe cleaner is extremely easy to be damaged due to deformation caused by overlarge pressure. When the pipe cleaner is seriously blocked, the oil pipeline is generally required to be cut to take out the pipe cleaner, and the production cost is seriously increased.
Meanwhile, the wax content in the oil pipeline is relatively high, and the expected effect of pipe cleaning cannot be achieved by adopting a common pipe cleaner.

FIG. 2 is a schematic view of the structure of an annular brush body according to an embodiment.
In the figure, 1 is a first shaft body, 2 is a first leather cup, 3 is a second leather cup, 4 is a guide plate, 5 is a bearing, 6 is a brush body, 7 is a second shaft body, and 8 is a connecting rod.
Detailed Description
The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto.
As shown in fig. 1 and fig. 2, the self-rotating oil pipeline anti-blocking cleaning device of the present embodiment includes a first shaft 1, a second shaft 7, a brush 6, and a first cup 2. The second shaft body 7 is rotatably connected with the first shaft body 1 through a bearing 5; the outer surface of the second shaft body 7 is provided with threads. The brush body 6 is annular and is sleeved outside the second shaft body 7, and the inner surface of the brush body 6 is connected with the outer surface of the second shaft body 7 through a connecting rod 8. The first leather cup 2 is sleeved outside the first shaft body 1 and is fixedly connected with the first shaft body 1. The brush body 6 is made of steel. The second shaft body 7 is located at the front section of the pig operation, and the first shaft body 1 is located at the rear section of the pig operation. The screw thread edge on the outer surface of the second shaft body 7 is pushed by the backward oil flow and blocked by the forward oil flow, so that the second shaft body 7 rotates. The second shaft body 7 drives the connecting rod 8 and the annular brush body 6 to rotate together, so that the brush body 6 can clean dirt on the pipe wall in the radial direction and can also clean dirt on the pipe wall in the transverse direction, and the pipe cleaning effect is better. First axis body 1 passes through bearing 5 with the second axis body 7 and is connected, can make second axis body 7 and first axis body 1 be swing joint, makes the pig more easily through positions such as pipeline elbow, reduces the stifled emergence of card, and the rotation of second axis body 7 can not drive first axis body 1 and rotate together simultaneously, has reduced the weight that needs driven, makes things convenient for the second axis body 7 pivoted to take place. Therefore, the pipe cleaning effect of the embodiment is good, the structure is simple, the requirements of oil pipelines with various structures can be met, and the blockage prevention performance is strong.
The second shaft body 7 is in a bullet shape with an angle of 45 degrees. The bullet-shaped second shaft body 7 can reduce the obstruction of front oil flow, reduce the blocking of a pipe cleaner and facilitate the rotation of the second shaft body 7. The bearing 5 is a single ball bearing 5; the single-ball bearing 5 comprises a shaft pin and a ball socket, the shaft pin is arranged at one end of the second shaft body 7 far away from the pointed end, and the ball socket is arranged at the end part of the first shaft body 1. The second shaft body 7 and the shaft pin are made of polyurethane materials, and the polyurethane materials can resist corrosion of oil flow, reduce the weight of the second shaft body 7 and facilitate rotation.
The embodiment further includes a second leather cup 3, and the second leather cup 3 is sleeved outside the first shaft 1 and is fixedly connected with the first shaft 1. The distance from the second cup 3 to the ball socket is smaller than the distance from the first cup 2 to the ball socket. The present embodiment further includes a guiding plate 4, and the guiding plate 4 is sleeved outside the first shaft 1 and is fixedly connected to the first shaft 1. The distance between the guide plate 4 and the ball socket is less than that between the second leather cup 3 and the ball socket. Namely, the first shaft body 1 is provided with a first leather cup 2, a second leather cup 3 and a guide plate 4 in sequence along the propelling direction of the pipe cleaner. The guide plate 4 supports the first shaft body 1 without an overall shift. The oil flow pushes the dish-shaped first cup 2, moving the pig forward. The disk-shaped second leather cup 3 pushes the pipe wall dirt scraped by the annular brush body 6 out of the pipeline.
The outer diameter of the bowl edge of the first leather cup 2 is the same as the inner diameter of the pipeline, so that the pipe cleaner has better trafficability characteristic, and blockage of the pipe cleaner is avoided. The bowl bottom orientation of first leather cup 2 is the same with the propulsion direction of dredging pipe ware, reduces the resistance that this dredging pipe ware marchd, and this dredging pipe ware of being convenient for can be propelled smoothly in oil pipeline. The outer diameter of the bowl edge of the second leather bowl 3 is slightly smaller than the inner diameter of the pipeline. The bowl bottom orientation of the second leather cup 3 is the same as the propelling direction of the pipe cleaner, so that the advancing resistance of the pipe cleaner is reduced, and the pipe cleaner can be smoothly propelled in an oil pipeline.
When the oil pipe scraper is used, the thread edge on the outer surface of the second shaft body 7 is pushed by rear oil flow and is blocked by front oil flow, so that the second shaft body 7 rotates to drive the connecting rod 8 and the annular brush body 6 to rotate together, and dirt on the pipe wall of an oil pipeline is scraped. The bullet-shaped second shaft body 7 reduces the obstruction of forward oil flow. Meanwhile, the second shaft body 7 is connected with the first shaft body 1 through the ball bearing 5, and the first shaft body 1 cannot rotate simultaneously. The guide plate 4 fixedly connected with the first shaft body 1 supports the first shaft body 1 without integral deviation. The oil flow pushes the dish-shaped first cup 2, which moves the pig forward. The disk-shaped second leather cup 3 pushes the dirt on the pipe wall just scraped by the annular brush out of the pipeline.
The above detailed description of the embodiments of the present invention provides those skilled in the art with changes in the detailed description and the drawings, and such changes should be considered as within the scope of the present invention.
