[0001] This utility model relates to the technical field of pipeline cleaning for petroleum machinery, and in particular to a pipeline cleaning device for petroleum machinery. Background Technology

[0002] After a certain period of operation, oil pipelines will accumulate deposits on their inner walls, requiring regular cleaning. Otherwise, it will affect the smooth flow of the pipeline and, in severe cases, cause blockages, thus affecting the pipeline's service life.

[0003] In the existing technology, cleaning pipes is a very troublesome task. Therefore, pipe cleaning devices are needed to clean pipes. The pipe cleaning device brushes the inner wall of the pipe and then rinses it with water to clean the inner wall of the pipe.

[0004] However, existing pipe cleaning devices are not convenient for brushing the inner walls of pipes with different inner diameters, resulting in low pipe cleaning efficiency and incomplete brushing of the inner walls of the pipes. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pipeline cleaning device for petroleum machinery that can conveniently brush the inner walls of pipes with different inner diameters, effectively improve pipeline cleaning efficiency, and make the inner walls of pipes more thoroughly brushed.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipeline cleaning device for petroleum machinery, comprising a drive mechanism and a brushing mechanism. The drive mechanism includes a fixed pipe and a handheld frame. A movable rod is slidably disposed inside the fixed pipe. A knob bolt is screwed onto the left end of the fixed pipe. A limiting groove is provided on the outer wall of the movable rod to cooperate with the knob bolt. The knob bolt is inserted into the limiting groove and the bottom end of the limiting groove is tightly pressed against it. A motor is fixedly mounted on the handheld frame. A connecting shaft is rotatably mounted on the left end of the handheld frame, and the right end of the connecting shaft is fixedly connected to the output end of the motor. The left end of the connecting shaft is connected to the movable rod. The right end of the moving rod is fixedly connected. The brushing mechanism includes three sets of cleaning plates. A fixed block is fixedly installed inside the left end of the fixed tube. A movable block is slidably installed inside the fixed tube. Three sets of guide grooves are provided in an annular pattern on the outer wall of the left side of the fixed tube. Three sets of guide seats that cooperate with the guide grooves are provided in an annular pattern on the outer walls of the fixed block and the movable block. Connecting strips are hinged to the six sets of guide seats. Two sets of hinge seats are symmetrically fixed on the inner side of each of the three sets of cleaning plates. The six sets of hinge seats are respectively hinged to the outer side of the six sets of connecting strips. The outer side of the three sets of cleaning plates is an arc surface, and brushes are provided on the outer side of each of the three sets of cleaning plates.

[0008] Preferably, the handheld frame has two sets of hand handles symmetrically fixedly connected.

[0009] Preferably, anti-slip handle covers are fixedly fitted onto the outer walls of both sets of hand handles.

[0010] Preferably, the outer wall of the knob on the knob bolt is provided with multiple sets of anti-slip protrusions arranged in a ring at equal intervals.

[0011] Preferably, both ends of the right side of the handheld device are rounded.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the operator adjusts the cleaning plate according to the inner diameter of the pipe to be cleaned. During adjustment, the knob bolt is loosened, allowing the limiting groove to slide to the left or be pulled to the right. When the limiting groove slides to the left, it pushes the movable block to the left, causing the movable block to push the cleaning plate outwards via the connecting strip, thus spreading the cleaning plate and making it suitable for cleaning pipes with larger inner diameters. When the limiting groove slides to the right, it drives the movable block to the right, causing the movable block to pull the cleaning plate inwards via the connecting strip, thus closing the cleaning plate and making it suitable for cleaning pipes with smaller inner diameters. Furthermore, by adjusting the cleaning plate, the brush can be made to rest against the inner wall of pipes with different inner diameters. Once the cleaning plate position is adjusted according to the pipe's inner diameter... Afterwards, tighten the knob bolts, hold the handle by hand, insert the fixed tube and cleaning plate into the pipe, and start the motor. The motor drives the connecting shaft to rotate, which in turn drives the movable rod to rotate. The movable rod, through the cooperation of the knob bolt and the limiting groove, and the cooperation of the guide groove and the guide seat, drives the fixed tube to rotate. The fixed tube, through the connection of the guide seat and the connecting strip, drives the cleaning plate to rotate. The rotation of the cleaning plate causes the brush to sweep the inner wall of the pipe. The operator can push the fixed tube back and forth axially through the handle by hand, and with the flushing of water, the brush sweeps the inner wall of the pipe axially. This makes it easy to sweep the inner walls of pipes with different inner diameters. Through the electric rotating brush, the contact between the brush and the inner wall, and the axial back and forth movement, the pipe cleaning efficiency can be effectively improved, and the inner wall of the pipe can be swept more thoroughly.

A movable rod 2 is slidably mounted inside the fixed pipe 1. A knob bolt 3 is screwed onto the left end of the fixed pipe 1. A limiting groove 4 is provided on the outer wall of the movable rod 2 to mate with the knob bolt 3. The knob bolt 3 is inserted into the limiting groove 4, with its bottom end tightly against the groove. A motor 7 is fixedly mounted on the handheld frame 6. A connecting shaft 5 is rotatably mounted on the left end of the handheld frame 6, and the right end of the connecting shaft 5 is fixedly connected to the output end of the motor 7. The left end of the connecting shaft 5 is fixedly connected to the right end of the movable rod 2. A fixing block 8 is fixedly mounted on the left end inside the fixed pipe 1. A movable block 9 is slidably mounted inside the fixed pipe 1. Three sets of guide grooves 10 are provided equidistantly in a ring on the outer left side of the fixed pipe 1. Both the fixed block 8 and the movable block 9 have three sets of guide seats 11 arranged equidistantly in a ring on their outer walls, which cooperate with the guide grooves 10. Each of the six sets of guide seats 11 is hinged with a connecting strip 12. Two sets of hinge seats 14 are symmetrically fixed to the inner sides of each of the three sets of cleaning plates 13. The six sets of hinge seats 14 are respectively hinged to the outer sides of the six sets of connecting strips 12. The outer sides of the three sets of cleaning plates 13 are curved, and each set of cleaning plates 13 has a brush 15 on its outer side. During use, the operator adjusts the cleaning plates 13 according to the inner diameter of the pipe to be cleaned. During adjustment, the knob bolt 3 is loosened, and then the limiting groove 4 can be pushed to the left or pulled to the right. When the limiting groove 4 slides to the left, it pushes the movable block 9 to slide to the left, causing... The movable block 9 pushes the cleaning plate 13 outward through the connecting strip 12, causing the cleaning plate 13 to expand, thus making it suitable for cleaning pipes with larger inner diameters. When the limiting groove 4 slides to the right, the limiting groove 4 drives the movable block 9 to slide to the right, causing the movable block 9 to pull the cleaning plate 13 inward through the connecting strip 12, causing the cleaning plate 13 to close, thus making it suitable for cleaning pipes with smaller inner diameters. Furthermore, by adjusting the cleaning plate 13, the brush 15 can be made to rest against the inner wall of pipes with different inner diameters. After the position of the cleaning plate 13 is adjusted according to the inner diameter of the pipe, the knob bolt 3 is tightened. By holding the holding bracket 6, the fixed tube 1 and the cleaning plate 13 are inserted into the pipe, and the motor 7 is started, causing the motor 7 to drive the connecting shaft 5 to rotate. The movable rod 2 rotates, and through the cooperation of the knob bolt 3 and the limiting groove 4, as well as the cooperation of the guide groove 10 and the guide seat 11, the movable rod 2 drives the fixed pipe 1 to rotate. The fixed pipe 1, through the connection of the guide seat 11 and the connecting strip 12, drives the cleaning plate 13 to rotate. The rotation of the cleaning plate 13 causes the brush 15 to brush the inner wall of the pipe. The operator can hold the holding frame 6 and push the fixed pipe 1 back and forth axially. With the flushing of water, the brush 15 brushes the inner wall of the pipe axially. This makes it convenient to brush the inner wall of pipes with different inner diameters. Through the electric rotating brush and the contact between the brush 15 and the inner wall and the axial back and forth movement, the pipe cleaning efficiency can be effectively improved, and the inner wall of the pipe can be brushed more thoroughly.

[0026] This utility model discloses a pipeline cleaning device for petroleum machinery. In operation, the operator adjusts the cleaning plate 13 according to the inner diameter of the pipeline to be cleaned. During adjustment, the knob bolt 3 is loosened, allowing the limiting groove 4 to slide to the left or right. When the limiting groove 4 slides to the left, it pushes the movable block 9 to slide to the left, causing the movable block 9 to push the cleaning plate 13 outward via the connecting strip 12, thus expanding the cleaning plate 13 for cleaning larger inner diameter pipelines. When the limiting groove 4 slides to the right, it drives the movable block 9 to slide to the right, causing the movable block 9 to pull the cleaning plate 13 inward via the connecting strip 12, thus closing the cleaning plate 13 for cleaning smaller inner diameter pipelines. The cleaning plate 13 can then be adjusted... All of these methods allow the brush 15 to rest against the inner wall of pipes with different inner diameters. After the cleaning plate 13 is adjusted to the pipe's inner diameter, tighten the knob bolt 3. Hold the handle 6 by hand, insert the fixed pipe 1 and the cleaning plate 13 into the pipe, and start the motor 7. The motor 7 drives the connecting shaft 5 to rotate, and the connecting shaft 5 drives the movable rod 2 to rotate. The movable rod 2 drives the fixed pipe 1 to rotate through the cooperation of the knob bolt 3 and the limiting groove 4, as well as the cooperation of the guide groove 10 and the guide seat 11. The fixed pipe 1 drives the cleaning plate 13 to rotate through the connection of the guide seat 11 and the connecting strip 12. The rotation of the cleaning plate 13 causes the brush 15 to brush the inner wall of the pipe. The operator can push the fixed pipe 1 back and forth axially through the handle 6 by hand, and with the flushing of water, the brush 15 brushes the inner wall of the pipe axially.
