Technical Field

[0001] The invention relates to the field of pipeline descaling, and in particular to a pipeline descaling device. Background Art

[0002] With the advancement of urbanization, the urban population continues to increase, and the demand for water resources also increases. More domestic sewage and industrial wastewater need to be discharged through the drainage network. In the industrial and commercial fields, cooling water pipes are usually used for heat dissipation and cooling equipment. If impurities such as scale accumulate inside the pipes, it will reduce the heat exchange efficiency, increase energy consumption and operating costs. Impurities and scale in the cooling water pipes may also cause pipe blockage and failure, resulting in equipment shutdown or damage. This will not only affect production efficiency and economic benefits, but may also cause safety hazards. Pipeline descaling methods include chemical descaling, mechanical descaling, high-pressure water descaling, physical resonance descaling, etc.

[0003] From the perspective of wide application, high-pressure water descaling and chemical descaling are the two most commonly used methods for pipeline descaling.

High-pressure water descaling equipment is expensive, which increases the subsequent maintenance cost, and requires professionals with certain operating skills and experience to operate, which increases labor costs. For pipes of certain special shapes or materials, high-pressure water descaling equipment is not flexible enough and cannot achieve the expected effect; chemical descaling refers to the use of chemical reagents to dissolve or decompose dirt and blockages in the pipeline. Chemical descaling may cause corrosion to the pipeline, pollute the environment, and has limited operating scenarios. Summary of the invention

[0015] (3) Beneficial effects 1. By setting a steering mechanism, the cleaning mechanism drives the cleaning shaft to tilt to one side to adapt to the angle of the pipeline. The tilt of the cleaning shaft drives the two steering gears to rotate and rotate around the transmission gear, which increases the flexibility of the device and can achieve better cleaning effects. The telescopic sleeve prevents scale and other impurities from entering the steering mechanism and affecting the operation of the steering mechanism, so as to maintain the flexibility of the device to adapt to more types of pipelines; by setting a cleaning mechanism, the output end of the driving motor drives the scraper to rotate with the cleaning shaft as the center of the circle, and the scraper rotates with the cleaning shaft as the center of the circle to drive the cleaning brush to clean the inner wall of the pipeline, thereby optimizing the structure of the pipeline descaling device, reducing the maintenance cost of the pipeline descaling device, reducing damage to the inner wall of the pipeline, and extending the service life of the pipeline; 2.

The two support wheels slide outward and contact the inner wall of the pipeline, providing support force for the device, so that the device is located in the center of the pipeline, which is convenient for the device to move and prevents the impurities swept down from affecting the operation of the device; by setting up a walking mechanism, the output end of the drive motor drives the support wheel to rotate, and the rotation of the support wheel pushes the device forward. When the diameter of the pipeline changes, the two tensioning wheels tighten the power belt, so that the device can still maintain driving force when facing pipelines of different diameters, and the drive device moves forward; 3. By setting up a flushing mechanism, water pushes the flushing shaft to rotate, and the rotation of the flushing shaft drives the water spray block to rotate. Water passes through the flushing blades and is sprayed out from the water spray hole. The rotation of the water spray block allows water to continuously flush the inner wall of the pipe and the impurities dropped after cleaning at all angles without causing pollution to the environment. The device can adapt to a variety of operating scenarios, improve the pipe descaling effect, and ensure the quality of pipe descaling. Under the action of the circular annular groove at the end of the flushing shaft and the circular annular groove on the side of the rotating ring, when the water spray block rotates, the device and the water pipe do not rotate, making the operation of the device more stable and preventing the water pipe from being damaged by force.

[0023] like Figure 6 , Figure 7As shown, the walking mechanism 3 includes a walking shaft 302, which is rotatably connected to the shell 1, and a walking gear 301 is fixedly connected to the outer side of the middle part of the walking shaft 302, and a first pulley 303 is fixedly connected to the side of the walking gear 301. A T-shaped groove is provided on the side of the square through hole of the shell 1, and two tensioning blocks 307 are slidably connected in the T-shaped groove. The cross-section of the tensioning block 307 is T-shaped, and the side of the tensioning block 307 is rotatably connected to a tensioning wheel 308 through a rotating shaft. When the diameter of the pipeline changes, the tensioning wheel 308 tightens the power belt 305 to maintain the driving force of the device.

[0024] like Figure 3 As shown, the other end of the shell 1 is fixedly connected to the driving motor 101, and the output end of the driving motor 101 is fixedly connected to the worm 102, the worm 102 is meshed with the traveling gear 301, and the other end of the worm 102 is rotatably connected to the shell 1, and the other end of the worm 102 penetrates the shell 1 and is fixedly connected to the transmission shaft 505.

The telescopic sleeve 4 is made of metal, and the telescopic sleeve 4 prevents the cleaned impurities and scale from affecting the smooth operation of the device.

[0025] like Figure 8 , Fig. 9As shown, the flushing mechanism 7 includes a fixed sleeve 701, which is fixedly connected to the side of the shell 1, and the fixed sleeve 701 is slidably connected to the driving motor 101. A circular hole is provided at the other end of the fixed sleeve 701, and a flushing shaft 702 is slidably connected in the circular hole. A circular annular groove is provided at the end of the flushing shaft 702, and four limiting bolts 8 are slidably connected in the circular annular groove. The limiting bolts 8 are threadedly connected to the fixed sleeve 701 through threads. A water spray block 703 is fixedly connected to the outside of the flushing shaft 702. The water spray block 703 is a truncated cone body, and a circular through hole is provided inside the water spray block 703. Six flushing blades 707 are fixedly connected to the outside of the flushing shaft 702 and located in the circular through holes of the water spray block 703. The flushing blades 707 are spirally arranged, and water flows through the flushing blades. When the sheet 707 is turned, the flushing shaft 702 is pushed to rotate. Six water spray holes 708 are provided on the arc-shaped side of the water spray block 703. The water spray holes 708 are set at a certain inclined angle so that the water flows to one end away from the device after being sprayed out, which is convenient for collecting the sewage after descaling. A rotating ring 704 is slidably connected to the other side of the water spray block 703. A circular ring groove is provided on the arc-shaped side of the rotating ring 704. Four limiting bolts 8 are slidably connected in the circular ring groove. The limiting bolts 8 are threadedly connected to the water spray block 703 through threads. The rotating ring 704 prevents the water pipe from rotating with the water spray block 703, thereby preventing the water pipe from being damaged by force and improving the service life of the water pipe. A water collecting block 705 is fixedly connected to the side of the rotating ring 704, and a water pipe connector 706 is fixedly connected to the side of the water collecting block 705.

[0026] When the device is used, the device is first placed at the end of the pipe to be descaled. At this time, the support mechanism 2 is opened to form a support between the inner wall of the pipe, the cleaning mechanism 6 is opened to contact the inner wall of the pipe, and then the water pipe of the flushing mechanism 7 is connected, and the power line of the drive motor 101 is connected. Then the drive motor 101 is started, and the drive motor 101 drives the walking mechanism 3 to drive the device forward. The drive motor 101 drives the steering mechanism 5 and the cleaning mechanism 6 to rotate to clean the scale attached to the inner wall of the pipe, and then the water pump is started to send water into the flushing mechanism 7 through the water pipe. The flushing mechanism 7 flushes the inner wall of the pipe and the impurities dropped after cleaning. When the pipe turns at a certain angle, the steering mechanism 5 can bend at a certain angle to adapt to the pipe with a certain angle.

[0027] When the device is placed at the end of the pipe to be descaled, one of the scrapers 606 is pressed downward, and the scraper 606 drives the linkage rack 605 to move downward synchronously. While the linkage rack 605 moves downward, the linkage gear 604 rotates counterclockwise, and the counterclockwise rotation of the linkage gear 604 drives the synchronous gear 603 to rotate clockwise. Under the action of the synchronous gear 603, the other five linkage gears 604 rotate counterclockwise synchronously, so that the other five linkage racks 605 move downward synchronously, and then the other five scrapers 606 move synchronously to the position of the cleaning shaft 601, so that the six scrapers 606 shrink into a circle. The shrinkage of the six scrapers 606 compresses the force storage spring 610. When the cleaning mechanism 6 enters the pipe and contacts the inner wall of the pipe, the pressure on the scraper 606 is released, and the force storage spring 610 is released. The pressure pushes the sliding block 609 to slide in the direction away from the cleaning shaft 601. The sliding block 609 slides in the direction away from the cleaning shaft 601, driving the scraper 606 to slide toward the pipe wall on the outside of the limit plate 607. The scraper 606 slides toward the pipe wall, driving the linkage rack 605 to slide toward the pipe wall. The linkage rack 605 is meshed with the linkage gear 604. The linkage rack 605 slides toward the pipe wall, driving the linkage gear 604 to rotate clockwise. The linkage gear 604 is meshed with the synchronous gear 603. The clockwise rotation of the linkage gear 604 drives the synchronous gear 603 to rotate counterclockwise. Under the action of the synchronous gear 603, the six scrapers 606 move toward the pipe wall synchronously. The movement of the scraper 606 toward the pipe wall pushes the cleaning brush 608 to contact the inner wall of the pipe. The device can adapt to pipes of various diameters, thereby improving the adaptability and flexibility of the device.

[0028] After the cleaning mechanism 6 enters the interior of the pipeline, it presses the four groups of support wheels 206 toward the middle position of the shell 1, so that the support wheels 206 move toward the direction of the shell 1, and the support wheels 206 push the other end of the support rod 204 to move toward the two ends of the shell 1. The movement of the support rod 204 pushes the two sliding seats 203 to move in the opposite direction through the rotating shaft 208, so that the support spring 202 accumulates force and contracts. When the support mechanism 2 enters the interior of the pipeline, the support wheel 206 is released, and the support spring 202 releases the pressure to push the two sliding seats 203 to move toward each other. The two sliding seats 203 move toward each other, driving the two rotating shafts 208 to move toward each other. Under the action of the connecting rod 205, the two rotating shafts 208 move toward each other. The movement toward the pipe pushes one end of the four support rods 204 to move toward each other, and the movement toward each other of the four support rods 204 drives the other end of the four support rods 204 to slide toward the pipe wall. The other end of the four support rods 204 slides toward the pipe wall and pushes the two connecting rods 205 to slide toward the pipe wall. The sliding of the two connecting rods 205 toward the pipe wall drives the two driving shafts 207 to slide toward the pipe wall. The sliding of the two driving shafts 207 toward the pipe wall drives the two support wheels 206 to slide toward the pipe wall. The four groups of support wheels 206 slide toward the pipe wall and contact the inner wall of the pipe, providing support force for the device, so that the device is located in the center of the pipe, which is convenient for the device to move, and at the same time prevents the impurities and scale swept down from affecting the operation of the device.

[0029] After the power cord of the driving motor 101 is connected, when the driving motor 101 drives the driving device of the walking mechanism 3 to move forward, the driving motor 101 is started, and the output end of the driving motor 101 drives the worm 102 to rotate, and the worm 102 is meshed and connected with the walking gear 301. The rotation of the worm 102 drives the walking gear 301 to rotate, and the rotation of the walking gear 301 drives the first pulley 303 to rotate. Under the action of the power belt 305, the first pulley 303 rotates the second pulley 304 to rotate, and the rotation of the second pulley 304 drives the driving shaft 207 to rotate, and the rotation of the driving shaft 207 drives the supporting wheel 206 to rotate, and the rotation of the supporting wheel 206 drives the device to move forward. When the inner diameter of the pipeline changes, the sliding seat 203 is pushed to slide toward or in the opposite direction under the action of the supporting spring 202, thereby driving the four groups of support wheels 206 to shrink or stretch at the same time to adapt to pipelines of different diameters.

[0030] When the device moves forward, the driving motor 101 drives the steering mechanism 5 and the cleaning mechanism 6 to rotate, and the output end of the driving motor 101 drives the worm 102 to rotate, and the rotation of the worm 102 drives the transmission shaft 505 to rotate, and the rotation of the transmission shaft 505 drives the limit shaft 507 to rotate with the transmission shaft 505 as the center of the circle, and the limit shaft 507 rotates with the transmission shaft 505 as the center of the circle and drives the steering rod 504 to rotate with the transmission shaft 505 as the center of the circle, and the steering rod 504 rotates with the transmission shaft 505 as the center of the circle and drives the steering shaft 506 The steering shaft 506 rotates around the cleaning shaft 601 as the center to drive the cleaning shaft 601 to rotate, the rotation of the cleaning shaft 601 drives multiple limit plates 607 to rotate around the cleaning shaft 601 as the center, the limit plates 607 rotate around the cleaning shaft 601 as the center to drive the scraper 606 to rotate around the cleaning shaft 601 as the center, the scraper 606 rotates around the cleaning shaft 601 as the center to drive the cleaning brush 608 to clean the inner wall of the pipeline, thereby reducing damage to the pipeline and extending the service life of the pipeline.

[0031] After the water pipe of the flushing mechanism 7 is connected, the water pump is started to send water into the flushing mechanism 7 through the water pipe. The water in the water pipe enters the water collecting block 705 through the water pipe joint 706. Under the action of the flushing blades 707 on the outside of the flushing shaft 702, the water hits the flushing blades 707 to push the flushing shaft 702 to rotate. The rotation of the flushing shaft 702 drives the water spray block 703 to rotate. The water flows through the flushing blades 707 and is sprayed out from the water spray hole 708. The rotation of the water spray block 703 allows the water to continuously rinse the inner wall of the pipeline and the impurities and scale that fall after cleaning at all angles. Under the action of the circular annular groove at the end of the flushing shaft 702 and the circular annular groove on the side of the rotating ring 704, when the water spray block 703 rotates, the device and the water pipe do not rotate, so that the operation of the device is more stable and the water pipe is prevented from being damaged by force.

[0032] When the pipeline turns at a certain angle, the steering mechanism 5 can bend at a certain angle to adapt to the pipeline with a certain inclination angle. In order to adapt to the pipeline with a certain inclination angle, the cleaning mechanism 6 tilts to one side and drives the cleaning shaft 601 to tilt to one side. The cleaning shaft 601 tilts to one side and drives the steering shaft 506 to tilt to one side. Under the limiting effect of the limit wheel 501, the transmission gear 502 cannot rotate. The steering shaft 506 tilts to one side and drives the two steering gears 503 to rotate and rotate around the transmission gear 502. At this time, the cleaning mechanism 6 tilts to one side at a certain angle and drives the device to pass through the pipeline, which increases the flexibility of the device and achieves a better cleaning effect. The telescopic sleeve 4 is arranged on the outside of the steering mechanism 5 to prevent impurities such as scale from entering the steering mechanism 5 and affecting the operation of the steering mechanism 5, thereby maintaining the flexibility of the device to adapt to more types of pipelines.

It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
