Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to an oil pipe cleaning device and a cleaning process. Background Art

[0002] Oil pipe cleaning devices are equipment specially used to clean the inner wall of oil pipes in the petroleum, chemical and other industries. These devices are designed to effectively remove oil, wax, scale and other deposits in the oil pipes to ensure smooth and efficient operation of the oil pipes.

[0003] A petroleum pipeline cleaning device is disclosed in Chinese patent publication number CN107262466B. The petroleum pipeline cleaning device is provided with a front variable diameter brush head device. When in use, the front variable diameter brush head device can be adjusted according to different pipe diameters, so that the cleaning effect is better when cleaning dirt.

[0004] However, compared with the existing technology in the related field, since the brush only rotates around the pipe wall and cleans the pipe wall in one direction, some dirt can easily pass through the gaps between the bristles, causing dirt residue. At the same time, since the inner wall of the pipe is not smooth, solid particles, precipitation and impurities in the oil pipe may be difficult to remove, resulting in poor cleaning effect. At the same time, if the hardness of the brush or the number of cleaning times is increased, the oil pipe may be easily damaged. Summary of the invention

[0009] Furthermore, a plurality of protrusions are fixedly provided on the plurality of arc-shaped protrusions and the plurality of arc-shaped grooves.

[0010] Furthermore, T-shaped slots are provided at positions of the fixed axis corresponding to the plurality of second hinged parts, the second hinged parts are slidably matched with the T-shaped slots, and the second hinged parts are connected with the T-shaped slots via elastic parts.

[0011] Furthermore, the driving assembly includes a motor arranged inside a mounting tube, a fixing plate is fixedly mounted on one end of the mounting tube close to the motor, the motor is fixedly mounted on the fixing plate, and an output end of the motor is connected to a fixed shaft via a plurality of soft belts.

[0012] Furthermore, a support plate is fixedly mounted on one end of the mounting tube located on the fixed shaft, a rotation hole is opened on the support plate at a position corresponding to the fixed shaft, and the fixed shaft is connected to the rotation hole through a bearing.

[0013] Furthermore, the cleaning component includes a ruler fixedly mounted on the outer surface of the sliding tube, a sleeve is slidably provided on the outer surface of the ruler, a brush is fixedly mounted on the end of the sleeve away from the ruler, a positioning bolt is threadedly connected to the outer surface of the sleeve for limiting its position after adjusting, and the spray component includes a fixed plate fixedly mounted on the end of the mounting tube, a plurality of spray heads are hinged on the outer surface of the fixed plate, and a movable hole is opened on the fixed plate at a position corresponding to the sliding tube.

[0014] Furthermore, the support assembly includes a plurality of electric push rods fixedly mounted on the outer surface of the mounting tube, a mounting plate is fixedly mounted on the output end of the electric push rod, and moving wheels are rotatably provided at both ends of the mounting plate.

[0015] A cleaning process of an oil pipe cleaning device comprises the following steps: S1. During cleaning, adjust the height of the mounting tube by the electric push rod of the support assembly so that the mounting tube is concentric with the oil pipe; S2. After the position of the installation pipe is adjusted, loosen the positioning bolts and then adjust the position of the casing. At this time, the position of the casing can be quickly adjusted according to the scale lines on the ruler surface so that the brush can press against the inner wall of the oil pipe. Then adjust the remaining cleaning components in turn. S3. After the cleaning assembly is adjusted, the liquid supply pipe is connected to the fixed plate so that the cleaning liquid can enter the fixed plate and then be sprayed out through multiple nozzles; S4. When the spray assembly is ready, the motor is started to twist the multiple soft belts together, thereby controlling the fixed shaft to rotate through the multiple soft belts; S5. When the fixed shaft rotates, the fixed shaft can drive the sliding tube to rotate through multiple multi-directional movable adjustment components, and then the sliding tube will drive multiple cleaning components to rotate circumferentially. At this time, the brush can clean the inner wall of the oil pipe in a rotating manner, and the cleaning liquid sprayed by multiple nozzles can improve the cleaning effect; S6. When the multi-directional movable adjustment component rotates with the fixed shaft, the ball of the support block will contact with multiple arc-shaped protrusions and multiple arc-shaped grooves. When the ball contacts the arc-shaped protrusion, the ball will prompt the support block to move to one side of the fixed shaft, and then through the cooperation between one of the support arms and the first hinge, the sliding tube is controlled to extend. At this time, the other support arm will prompt the second hinge to slide inside the T-shaped slide groove and pull the elastic member. When the ball contacts the arc-shaped groove, the pulling force of the elastic member will prompt the support block to move to the side away from the fixed shaft through the support arm, and then through the cooperation between the support arm and the first hinge, the sliding tube is controlled to be retracted, thereby realizing sliding. The moving pipe performs axial reciprocating sliding while rotating circumferentially, thereby realizing that the brush member cleans the pipe wall while rotating circumferentially and sliding axially. The axial reciprocating sliding of the brush member has the following effects on pipe cleaning: first, the brush can rub against the inner wall of the pipe for many times, thereby more effectively removing dirt, oil stains, scale and other sediments in the pipe; second, it can ensure that all parts of the inner wall of the pipe are cleaned evenly, reducing the dirt residue caused by uneven cleaning; third, it can help loosen and remove particles and fibrous substances that may cause pipe blockage; fourth, it can improve cleaning efficiency and reduce cleaning time; S7. By using the multiple protrusions on the arc-shaped protrusions and the arc-shaped grooves, when the ball moves between the multiple arc-shaped protrusions and the multiple arc-shaped grooves, the sliding tube can be driven to drive the cleaning component to vibrate (at this time, the soft belt can be used to prevent the vibration from being transmitted to the motor and prevent the motor from being directly affected by the vibration). The brush member has the following effects when it vibrates when cleaning the inner wall of the pipe: first, it can make the contact between the brush member and the inner wall of the pipe more complete, further helping the bristles to penetrate into the tiny gaps on the inner wall of the pipe, so as to more effectively remove dirt and sediment; second, it helps the brush member to cover every corner of the inner wall of the pipe, further making the cleaning process more uniform and reducing the dirt residue caused by incomplete local cleaning; third, it can help loosen and remove particles and fibrous substances that may block the pipe, further reducing the risk of pipe blockage; S8. The moving wheel control device is moved inside the oil pipe to complete the cleaning of the pipe wall.

[0016] The beneficial effects of the present invention are as follows: by setting a fixed shaft, a sliding tube, a multi-directional movable adjustment component and a touch component, and utilizing the cooperation between the multi-directional movable adjustment component and the touch component, on the one hand, the fixed shaft can drive the sliding tube to rotate circumferentially while performing axial reciprocating sliding, so that the brush member can clean the pipe wall while rotating circumferentially and sliding axially reciprocatingly. The axial reciprocating sliding of the brush member has the following effects on pipe cleaning: first, the brush can rub against the inner wall of the pipe for multiple times, so as to more effectively remove dirt, oil stains, scale and other sediments in the pipe; second, it can ensure that all parts of the inner wall of the pipe are cleaned evenly, reducing the dirt residue caused by uneven cleaning; third, it can help loosen and remove the dirt that may cause the pipe to become dirty. Blocked particles and fibrous substances; fourthly, it can improve cleaning efficiency and reduce cleaning time. On the other hand, the use of multiple bumps on the arc-shaped protrusions and arc-shaped grooves can make the sliding tube drive the cleaning component to shake. The brush part has the following effects when it shakes when cleaning the inner wall of the pipe: first, it can make the contact between the brush part and the inner wall of the pipe more complete, further helping the bristles to penetrate into the tiny gaps on the inner wall of the pipe, so as to more effectively remove dirt and sediment; second, it helps the brush part to cover every corner of the inner wall of the pipe, further making the cleaning process more uniform and reducing dirt residue caused by incomplete local cleaning; third, it can help loosen and remove particles and fibrous substances that may block the pipe, further reducing the risk of pipe blockage.

When the fixed shaft 2 rotates, the multiple multi-directional movable adjustment components 6 are used to drive the sliding tube 4 to rotate synchronously. When the multiple multi-directional movable adjustment components 6 rotate with the fixed shaft 2, the trigger component 7 is utilized to make the multi-directional movable adjustment component 6 control the sliding tube 4 to perform axial reciprocating sliding on the outer surface of the fixed shaft 2. The outer surface of the mounting tube 1 is provided with a support component 8 for controlling the mounting tube 1 to remain at the center of the oil pipe. A spray component 9 for spraying cleaning liquid onto the inner wall of the oil pipe is fixedly installed at one end of the mounting tube 1 close to the cleaning component 5.

[0022] As shown in Figure 4 to Fig.10 As shown, the trigger assembly 7 includes an annular member 701 fixedly mounted on the inner wall of the mounting tube 1, and the inner wall of the annular member 701 is provided with a plurality of arc-shaped protrusions 702 and a plurality of arc-shaped grooves 703, and the plurality of arc-shaped protrusions 702 and the plurality of arc-shaped grooves 703 are staggered and arranged to form a circle, and the multi-directional movable adjustment assembly 6 includes a support block 601, and both ends of the support block 601 are hinged with support arms 602, the sliding tube 4 is hinged to one of the support arms 602 through a first hinge 603, and the fixed shaft 2 is hinged to the other support arm 602 through a second hinge 604.

[0023] In summary: As shown in Figures 4 to Fig.10As shown, when the multi-directional movable adjustment component 6 rotates with the fixed shaft 2, the ball 605 of the support block 601 will contact the multiple arc-shaped protrusions 702 and the multiple arc-shaped grooves 703. When the ball 605 contacts the arc-shaped protrusions 702, the ball 605 will cause the support block 601 to move to one side of the fixed shaft 2, and then through the cooperation between one of the support arms 602 and the first hinge 603, the sliding tube 4 is controlled to extend. At this time, the other support arm 602 will cause the second hinge 604 to slide inside the T-shaped slide groove 201 and pull the elastic When the ball 605 contacts the arc groove 703, the tension of the elastic member 202 will cause the support block 601 to move to the side away from the fixed shaft 2 through the support arm 602, and then the support arm 602 and the first hinge member 603 cooperate to control the sliding tube 4 to retract, so that the sliding tube 4 can reciprocate axially while rotating circumferentially, and then the brush member 503 can reciprocate axially while rotating circumferentially to clean the pipe wall. The axial reciprocating sliding of the brush member 503 has the following effects on the cleaning of the pipe: Enhanced cleaning effect: The axial reciprocating sliding allows the brush to rub against the inner wall of the pipe multiple times, thereby more effectively removing dirt, oil stains, scale and other deposits in the pipe; Improve cleaning uniformity: through the reciprocating motion of the brush member 503, it can be ensured that all parts of the inner wall of the pipeline are cleaned uniformly, reducing the dirt residue caused by uneven cleaning; Deep cleaning: The reciprocating sliding can make the bristles of the brush member 503 penetrate into the smaller diameter areas and corners of the pipe to clean those hard-to-reach areas; Reduced risk of blockage: The reciprocating motion of the brush helps loosen and remove particles and fibrous material that may cause pipe blockage; Improve work efficiency: by combining the axial reciprocating sliding of the brush member 503 with the rotation of the brush member 503, the cleaning efficiency can be improved and the cleaning time can be reduced; As shown in Figure 3 to Fig.10 As shown, by using the multiple protrusions 704 on the arc-shaped protrusions 702 and the arc-shaped grooves 703, when the ball 605 moves between the multiple arc-shaped protrusions 702 and the multiple arc-shaped grooves 703, the sliding tube 4 can drive the cleaning component 5 to vibrate (at this time, the soft belt 303 is used to prevent the vibration from being transmitted to the motor 301, and the motor 301 is prevented from being directly affected by the vibration). When the brush member 503 vibrates while cleaning the inner wall of the pipe, the following effects will be produced: Improve cleaning effect: shaking can make the contact between the brush member 503 and the inner wall of the pipe more complete, further helping the bristles to penetrate into the tiny gaps in the inner wall of the pipe, thereby more effectively removing dirt and sediment; Improve cleaning uniformity: The shaking helps the brush member 503 to cover every corner of the inner wall of the pipe, further making the cleaning process more uniform and reducing the dirt residue caused by incomplete local cleaning; Reduced risk of blockage: Shaking can help loosen and remove particles and fibrous material that may be clogging the pipe, further reducing the risk of pipe blockage; Improving the service life of the brush: by shaking, the damage of the bristles of the brush member 503 caused by local excessive wear during long-term use can be reduced, thereby extending the service life of the brush member 503.

[0024] As shown in Figures 3 to 7, the driving component 3 includes a motor 301 arranged inside the mounting tube 1, and a fixing plate 302 is fixedly installed at one end of the mounting tube 1 close to the motor 301. The motor 301 is fixedly installed on the fixing plate 302. The output end of the motor 301 is connected to the fixed shaft 2 through multiple soft belts 303. By starting the motor 301, the multiple soft belts 303 are twisted together, so that the rotation of the fixed shaft 2 is controlled by the multiple soft belts 303. At the same time, when the sliding tube 4 drives the cleaning component 5 to shake, the set soft belt 303 can be used to prevent the shaking from being transmitted to the motor 301, thereby preventing the motor 301 from being directly affected by the shaking.

[0025] As shown in FIG3 , the cleaning assembly 5 includes a scale 501 fixedly mounted on the outer surface of the sliding tube 4, a sleeve 502 is slidably provided on the outer surface of the scale 501, a brush 503 is fixedly mounted on one end of the sleeve 502 away from the scale 501, and a positioning bolt 504 is threadedly connected to the outer surface of the sleeve 502 for limiting its position after adjusting its position. By loosening the positioning bolt 504 and then adjusting the position of the sleeve 502, the position of the sleeve 502 can be quickly adjusted according to the scale lines on the surface of the scale 501, so that the brush 503 can press against the inner wall of the oil pipe, thereby automatically changing according to the diameter of the inner wall of the pipe, so that the brush 503 can squeeze the inner wall of the pipe. The pressure is maintained at a certain value to keep the cleaning force constant. Appropriate brush bristle material and pressure setting can avoid damage to the inner wall of the pipe. As shown in Figures 2 and 3, the spray assembly 9 includes a fixed plate 901 fixedly installed at the end of the mounting tube 1. The outer surface of the fixed plate 901 is hinged with multiple nozzles 902. The fixed plate 901 is provided with a movable hole at a position corresponding to the sliding tube 4. The fixed plate 901 is provided with a liquid supply port, which can be connected to an external water pipe. By adjusting the angles of the multiple nozzles 902 according to the inner diameter of the oil pipe, the fixed plate 901 is connected to the external liquid supply pipe, so that the cleaning liquid can enter the fixed plate 901 and then be sprayed out through the multiple nozzles 902.

[0026] As shown in Figure 3, the support assembly 8 includes a plurality of electric push rods 801 fixedly mounted on the outer surface of the mounting tube 1, and a mounting plate 802 is fixedly mounted on the output end of the electric push rod 801. Both ends of the mounting plate 802 are rotatably provided with moving wheels 803. During cleaning, the height of the mounting tube 1 can be adjusted by the electric push rods 801 of the support assembly 8 so that the mounting tube 1 is concentric with the oil pipe.

[0027] The motor 301, the electric push rod 801 and the spray assembly 9 described in the present application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0028] The cleaning process of the oil pipe cleaning device is as follows: S1, as shown in FIG. 1 to FIG. 3, during cleaning, the height of the mounting tube 1 is adjusted by the electric push rod 801 of the support assembly 8 so that the mounting tube 1 is concentric with the oil pipe; S2. As shown in FIGS. 1 to 3, after the position of the mounting tube 1 is adjusted, the positioning bolt 504 is loosened, and then the position of the sleeve 502 is adjusted. At this time, the position of the sleeve 502 can be quickly adjusted according to the scale lines on the surface of the ruler 501, so that the brush member 503 can press against the inner wall of the oil pipe, and then the remaining cleaning components 5 are adjusted in turn; S3, as shown in FIGS. 1 to 3, after the cleaning assembly 5 is adjusted, the fixed disk 901 is connected to a liquid supply pipe so that the cleaning liquid can enter the fixed disk 901 and then be sprayed out through the multiple nozzles 902; S4, as shown in FIG. 2, FIG. 5 and FIG. 7, when the spray assembly 9 is ready, the motor 301 is started to twist the multiple soft belts 303 together, thereby controlling the rotation of the fixed shaft 2 through the multiple soft belts 303; S5, as shown in Figures 2, 4, 5, 6 and 7, when the fixed shaft 2 rotates, the fixed shaft 2 can drive the sliding tube 4 to rotate through the multiple multi-directional movable adjustment components 6, and then the sliding tube 4 will drive the multiple cleaning components 5 to rotate circumferentially, at this time, the brush member 503 can clean the inner wall of the oil pipe in a rotating manner, and at the same time, the cleaning liquid sprayed by the multiple nozzles 902 can improve the cleaning effect; S6, as shown in Figure 4 to Fig.10As shown, when the multi-directional movable adjustment component 6 rotates with the fixed shaft 2, the ball 605 of the support block 601 will contact the multiple arc-shaped protrusions 702 and the multiple arc-shaped grooves 703. When the ball 605 contacts the arc-shaped protrusions 702, the ball 605 will prompt the support block 601 to move to one side of the fixed shaft 2, and then through the cooperation between one of the support arms 602 and the first hinge 603, the sliding tube 4 is controlled to extend. At this time, the other support arm 602 will prompt the second hinge 604 to slide inside the T-shaped slide groove 201 and pull the elastic member 202. When the ball 605 contacts the arc-shaped groove 703, the pulling force of the elastic member 202 will prompt the support block 601 to move to the side away from the fixed shaft 2 through the support arm 602, and then through the support arm 6 02 cooperates with the first hinge 603 to control the retraction of the sliding tube 4, so that the sliding tube 4 can perform axial reciprocating sliding while rotating circumferentially, thereby realizing that the brush member 503 can clean the pipe wall while rotating circumferentially and sliding axially. The axial reciprocating sliding of the brush member 503 has the following effects on pipe cleaning: first, the brush can rub against the inner wall of the pipe for multiple times, so as to more effectively remove dirt, oil stains, scale and other sediments in the pipe; second, it can ensure that all parts of the inner wall of the pipe are cleaned evenly, reducing the dirt residue caused by uneven cleaning; third, it can help loosen and remove particles and fibrous substances that may cause pipe blockage; fourth, it can improve cleaning efficiency and reduce cleaning time; S7, as shown in Figure 3 to Fig.10 As shown, by utilizing the multiple protrusions 704 on the arc-shaped protrusions 702 and the arc-shaped grooves 703, when the ball 605 moves between the multiple arc-shaped protrusions 702 and the multiple arc-shaped grooves 703, the sliding tube 4 can drive the cleaning component 5 to vibrate (at this time, utilizing the provided soft belt 303 can prevent the vibration from being transmitted to the motor 301, and prevent the motor 301 from being directly affected by the vibration). The brush member 503 has the following effects when vibrating when cleaning the inner wall of the pipe: first, it can make the contact between the brush member 503 and the inner wall of the pipe more complete, further helping the bristles to penetrate into the tiny gaps on the inner wall of the pipe, thereby more effectively removing dirt and sediments; second, it can help the brush member 503 cover every corner of the inner wall of the pipe, further making the cleaning process more uniform, and reducing the dirt residue caused by incomplete local cleaning; third, it can help loosen and remove particles and fibrous substances that may clog the pipe, further reducing the risk of pipe clogging; S8. As shown in FIG. 1 to FIG. 3, the moving wheel 803 controls the device to move inside the oil pipe to complete the cleaning of the pipe wall.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

10. A cleaning process based on the oil pipe cleaning device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. During cleaning, the height of the mounting tube (1) is adjusted by the electric push rod (801) of the support assembly (8) so that the mounting tube (1) is concentric with the oil pipe; S2. After the position of the mounting tube (1) is adjusted, the positioning bolt (504) is loosened and the position of the sleeve (502) is adjusted. At this time, the position of the sleeve (502) can be quickly adjusted according to the scale lines on the surface of the ruler (501), so that the brush member (503) can be pressed against the inner wall of the oil pipe, and then the remaining cleaning components (5) are adjusted in turn; S3, when the cleaning component (5) is adjusted, the fixed disk (901) is connected to an external liquid supply pipe so that the cleaning liquid can enter the fixed disk (901) and then be sprayed out through the multiple nozzles (902); S4, when the spray assembly (9) is ready, the motor (301) is started to twist the plurality of flexible belts (303) together, thereby controlling the fixed shaft (2) to rotate through the plurality of flexible belts (303); S5. When the fixed shaft (2) rotates, the fixed shaft (2) can drive the sliding tube (4) to rotate through the multiple multi-directional movable adjustment components (6), and then the sliding tube (4) drives the multiple cleaning components (5) to rotate in a circumferential direction. At this time, the brush member (503) can clean the inner wall of the oil pipe in a rotating manner, and at the same time, the cleaning liquid sprayed by the multiple nozzles (902) can improve the cleaning effect; S6. When the multi-directional movable adjustment component (6) rotates with the fixed shaft (2), the ball (605) of the support block (601) will contact the multiple arc-shaped protrusions (702) and the multiple arc-shaped grooves (703). When the ball (605) contacts the arc-shaped protrusions (702), the ball (605) will cause the support block (601) to move toward one side of the fixed shaft (2). Then, through the cooperation between one of the support arms (602) and the first hinge (603), the sliding tube (4) is controlled to extend. At this time, the other support arm (602) will cause the second hinge (604) to slide inside the T-shaped slide groove (201) and pull the elastic member (202). When the ball (605) contacts the arc-shaped groove (703), the pulling force of the elastic member (202) will cause the support block (601) to move toward the fixed shaft (2). The brush (503) moves away from the fixed axis (2), and then controls the sliding tube (4) to retract through the cooperation between the support arm (602) and the first hinge (603), so that the sliding tube (4) can perform axial reciprocating sliding while rotating circumferentially, thereby achieving the brush member (503) to clean the pipe wall while rotating circumferentially and sliding axially. The axial reciprocating sliding of the brush member (503) has the following effects on pipe cleaning: first, the brush can rub against the inner wall of the pipe for multiple times, so as to more effectively remove dirt, oil stains, scale and other sediments in the pipe; second, it ensures that all parts of the inner wall of the pipe are cleaned evenly, reducing dirt residue caused by uneven cleaning; third, it helps to loosen and remove particles and fibrous materials that may cause pipe blockage; fourth, it improves cleaning efficiency and reduces cleaning time; S7. By using the plurality of protrusions (704) on the arc-shaped protrusions (702) and the arc-shaped grooves (703), the ball (605) can be moved between the plurality of arc-shaped protrusions (702) and the plurality of arc-shaped grooves (703), thereby causing the sliding tube (4) to drive the cleaning component (5) to vibrate. The brush member (503) has the following effects when vibrating while cleaning the inner wall of the pipe: firstly, the contact between the brush member (503) and the inner wall of the pipe is more complete, further helping the bristles to penetrate into the tiny gaps on the inner wall of the pipe, thereby more effectively removing dirt and sediments; secondly, it helps the brush member (503) to cover every corner of the inner wall of the pipe, further making the cleaning process more uniform and reducing dirt residue caused by incomplete local cleaning; thirdly, it helps to loosen and remove particles and fibrous substances that may clog the pipe, thereby further reducing the risk of pipe clogging; S8. The moving wheel (803) controls the device to move inside the oil pipe, thereby completing the cleaning of the pipe wall.
