Description

Technical Field

[0001] This invention relates to the field of municipal pipeline dredging equipment technology, specifically to a municipal pipeline dredging device. Background Technology

[0002] As cities develop, there is more and more debris on the roads. When there is too much rain, the debris will enter the sewers with the rainwater, causing blockages. The traditional method of dredging is to manually dredge the pipes with some simple tools. This method is not only ineffective but also labor-intensive. For long pipes that are inaccessible to some people, mechanical digging with a dredging truck is used, but mechanical digging is inefficient and does not clean thoroughly.

[0003] Chinese patent (application number: CN201810137528.1) discloses a municipal pipeline dredging device, including a dredging vehicle equipped with a high-pressure water pipe, and a dredging scraper ring that fits into the inner wall of the pipeline. The dredging scraper ring is equipped with a sludge collection bag for collecting impurities in the pipeline and a spray head connected to the high-pressure water pipe to drive the dredging scraper ring to slide in the pipeline. The dredging scraper ring has an inclined scraping surface, and one end of the scraping surface that fits into the inner wall of the pipeline forms a pointed tip for scraping away the sludge accumulated on the inner wall of the pipeline.

[0004] The patent and existing technologies have the following technical problems in practical use:

[0005] 1. Due to the long-term closed nature of sewage pipes, organic matter in sewage (such as stalks, weeds, leaves, human and animal excrement, and industrial and agricultural waste containing organic matter) under certain temperature, humidity, acidity, and oxygen-deficient conditions undergoes microbial fermentation to produce a mixed gas, namely biogas. Biogas (containing toxic and harmful gases such as hydrogen sulfide, ammonia, and carbon monoxide) is a flammable and explosive gas. Over time, it may cause an explosion when exposed to sparks or increased pressure. Before cleaning the pipes, the pipes must be fully ventilated to ensure that harmful gases are expelled. This municipal pipe dredging device cannot expel the gas in the pipes during dredging, and the dredging shovel is prone to generating static electricity when scraping against the inner wall of the pipe, increasing the risk of explosion inside the pipe.

[0006] 2. The municipal pipeline dredging device has a bulky structure and high resistance to movement inside the pipeline. Therefore, when the blockage inside the pipeline is severe, a large driving force is required to move the dredging device forward, which makes it unable to move quickly and thus results in low dredging efficiency.

[0007] 3. The pressure between the municipal pipeline dredging device and the inner wall of the pipeline remains constant. Therefore, when the amount of silt in the pipeline is large and the silt is tightly adhered and difficult to remove, the device cannot completely remove the silt in one go, resulting in the need to dredge the pipeline multiple times and poor dredging effect.

[0008] 3. This municipal pipeline dredging device is not suitable for dredging pipelines of different radii. Therefore, when the pipeline radius is large, the device is unstable in its movement within it, and the device cannot enter the pipeline when the radius is large, resulting in the inability to dredge pipelines of different radii, and thus making it inconvenient to use.

The dredging process is highly safe.

[0057] 2. The present invention uses a dredging mechanism that is rope-shaped and pressed against the inner wall of the municipal pipeline. The municipal pipeline is flushed by scraping and high-pressure water jetting through the dredging mechanism. It not only has high cleaning efficiency, but also has a simple structure and low dredging resistance.

[0058] 3. This invention, through the setting of the telescopic adjustment mechanism, can adjust the length and angle of the dredging mechanism inside the municipal pipeline, thereby changing the distance between the dredging mechanism and the center of the device, which in turn changes the dredging radius, making the device suitable for cleaning the same pipeline and convenient to use.

[0059] 4. This invention, through the setting of the telescopic adjustment mechanism, can adjust the angle of the sludge removal mechanism inside the municipal pipeline, thereby changing the angle between the sludge removal mechanism and the inner wall of the pipeline. High-pressure water can be sprayed onto the sludge removal mechanism at different angles, thereby changing the pressure exerted by the sludge removal mechanism on the inner wall of the pipeline. When the sludge is more stubborn, the scraping pressure is increased, and the sludge can be scraped off in one go. It is suitable for pipelines with different degrees of pollution and has a good sludge removal effect. Attached Figure Description

[0068] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0069] A preferred embodiment of the municipal pipeline dredging device according to the present invention will be described in detail below. Figures 1-7 As shown, a municipal pipeline dredging device includes: a drive mechanism 1, a support mechanism 2, a dredging mechanism 3, and a telescopic adjustment mechanism 4 placed on the ground. The support mechanism 2 can be installed in the municipal pipeline. The dredging mechanism 3 runs through the interior of the support mechanism 2. The dredging mechanism 3 is used to scrape and wash the inner wall of the pipeline. The telescopic adjustment mechanism 4 is provided at the center of the support mechanism 2. The adjustment mechanism 4 is used to adjust the length and angle of the dredging mechanism 3 inside the municipal pipeline.

[0070] When in use, place the drive mechanism 1 on the ground, then install the support mechanism 2 at the port of the municipal pipeline. After installation, insert the sludge removal mechanism 3 into the municipal pipeline and install it on the drive mechanism 1. The sludge removal mechanism 3 does not contact the inner wall of the pipeline at first, and then the drive mechanism 1 drives the sludge removal mechanism 3 to rotate, thereby ventilating the municipal pipeline. The sludge removal is highly safe.

[0071] Then, the sludge removal mechanism 3 is made to go deeper into the municipal pipeline. The sludge removal mechanism 3 is pressed against the inner wall of the municipal pipeline. At this time, the drive mechanism 1 drives the sludge removal mechanism 3 to rotate, thereby cleaning the municipal pipeline.

[0072] The municipal pipeline is flushed by the scraping and high-pressure water jetting of the dredging mechanism 3, which not only has high cleaning efficiency, but also has a simple structure and low dredging resistance.

[0073] By setting the telescopic adjustment mechanism 4, the length and angle of the sludge removal mechanism 3 inside the municipal pipeline can be adjusted, so that the device can be used for cleaning the same pipeline and can clean municipal pipelines of different lengths, making it convenient to use.

[0074] Specifically, the drive mechanism 1 includes: a slide rail 11 placed on the ground, a slide block 12, a drive motor 13, a drive wheel 14, and a driven wheel 15. The slide block 12 is slidably connected inside the slide rail 11. The drive motor 13 is installed on the top of the slide block 12. The drive wheel 14 is installed at the output end of the drive motor 13. The driven wheel 15 is rotatably installed on the outside of the slide block 12. The driven wheel 15 meshes with the drive wheel 14. An installation sleeve is provided inside the driven wheel 15. The sludge removal mechanism 3 is connected to the installation sleeve in a transmission manner.

[0075] When an external power source is connected, the drive motor 13 is powered on and rotates. The drive motor 13 drives the driving wheel 14 to rotate, the driving wheel 14 drives the driven wheel 15 to rotate, the driven wheel 15 drives the mounting sleeve to rotate, and the mounting sleeve drives the dredging mechanism 3 to rotate. When the dredging mechanism 3 extends or retracts, the dredging mechanism 3 drives the mounting sleeve to move, the mounting sleeve drives the driven wheel 15 to move, and the driven wheel 15 drives the slide block 12 to slide along the slide rail 11, resulting in stable transmission.

[0076] Specifically, the support mechanism 2 includes: a support frame 21, a sliding rod 22, a clamping block 23, a guide block 24, an adjusting plate 25, an arc-shaped guide groove 26, a support ring 27, a locking bolt 28, and a locking plate 29. The support frame 21 can be installed in municipal pipelines. The outer side of the support frame 21 has an annular sliding hole, and the sliding rod 22 is slidably connected inside the sliding hole. The clamping block 23 is provided on the outer side of the sliding rod 22, and the guide block 24 is provided on the outer side of the sliding rod 22. The adjusting plate 25 is rotatably installed inside the support frame 21. The arc-shaped guide groove 26 is provided inside the adjusting plate 25, and the guide block 24 is inserted into the arc-shaped guide groove 26. The outer side of the support frame 21 has a support ring 27. A clamping cavity is provided between the support ring 27 and the adjusting plate 25. The support ring 27 has a threaded hole, and the locking bolt 28 is threadedly connected inside the threaded hole. The locking plate 29 is slidably connected inside the clamping cavity and is rotatably mounted on the locking bolt 28.

[0077] Insert the support frame 21 into the municipal pipeline port. Rotate the adjusting plate 25. The adjusting plate 25 pushes the slide rod 22 to slide outward of the support frame 21 through the arc-shaped guide groove 26 and the guide block 24. The slide rod 22 drives the clamping block 23 to move outward of the support frame 21. Through the setting of multiple sets of clamping blocks 23, the support frame 21 can be stably installed in the municipal pipeline. Then rotate the locking bolt 28. The locking bolt 28 drives the locking plate 29 to press on the adjusting plate 25. The locking plate 29 locks the adjusting plate 25 through friction. The adjusting plate 25 locks the clamping block 23, ensuring that the support frame 21 is fixed and stable.

[0078] Furthermore, friction grooves are provided on the contact surfaces of the adjusting disc 25 and the locking plate 29, as well as on the outer surface of the clamping block 23. This design improves the stability of the support frame 21.

[0079] Furthermore, the dredging mechanism 3 includes: a transmission flexible rod 31, a water guide hole 32, a spiral groove 33, a nozzle 34, and a cleaning head 35. The transmission flexible rod 31 is installed inside the mounting sleeve. The transmission flexible rod 31 passes through the support frame 21 and the telescopic adjustment mechanism 4. The transmission flexible rod 31 has a water guide hole 32 inside. The water guide hole 32 is connected to an external high-pressure water pump through a water pipe. The transmission flexible rod 31 has a spiral groove 33 on its outer side. The nozzle 34 is provided at the end of the transmission flexible rod 31 away from the mounting sleeve. The cleaning head 35 is hinged to the outer side of the nozzle 34.

[0080] With the transmission flexible rod 31 in place, power can be transmitted even at bends. The drive can be installed on the ground to transmit rotational force to the municipal pipeline. An external high-pressure water pump uses a water pipe and a water guide hole 32 to spray high-pressure water from the nozzle 34 to flush the inner wall of the pipeline. The cleaning head 35 can improve the sludge removal effect. At the same time, when the high-pressure water passes through the water guide hole 32, it can improve the structural strength of the transmission flexible rod 31, resulting in a better cleaning effect. The transmission flexible rod 31 is a wear-resistant polyurethane rubber elastic rod with a long service life.

[0081] Furthermore, a scraper 36 is linearly arranged on the outer surface of the cleaning head 35, and the height of the scraper 36 is distributed in an arc shape. A spray hole 37 is opened inside the cleaning head 35. The scraper 36 enables the cleaning head 35 to clean sludge more efficiently, and the spray hole 37 enables the cleaning head 35 to be rinsed when the spray head 34 is facing the cleaning head 35.

[0082] Furthermore, the telescopic adjustment mechanism 4 includes: a first guide sleeve 41, a protrusion 42, a second guide sleeve 43, a guide hole 44, and an adjustment sleeve frame 45. The first guide sleeve 41 is rotatably installed inside the support frame 21, and the transmission flexible rod 31 passes through the first guide sleeve 41. The inner wall of the first guide sleeve 41 is provided with a protrusion 42, which is engaged with the spiral groove 33. The second guide sleeve 43 is rotatably installed inside the first guide sleeve 41, and the second guide sleeve 43 is provided with a guide hole 44, through which the transmission flexible rod 31 passes. The outer side of the second guide sleeve 43 is provided with a swingable adjustment sleeve frame 45, through which the transmission flexible rod 31 passes.

[0083] Initially, the transmission rod 31 passes through the guide hole 44 and the adjusting sleeve 45. The transmission rod 31 is radially distributed along the municipal pipeline via one end of the support frame 21. At this time, the external power supply is connected to energize and rotate the drive motor 13. The drive motor 13 drives the drive wheel 14 to rotate, the drive wheel 14 drives the driven wheel 15 to rotate, the driven wheel 15 drives the mounting sleeve to rotate, and the mounting sleeve drives the transmission rod 31 to rotate. The transmission rod 31 drives the first guide sleeve 41 to rotate through the spiral groove 33 and the protrusion 42. Since the transmission rod 31 passes through the guide hole 44 in the second guide sleeve 43, the transmission rod 31 also drives the second guide sleeve 43 to rotate. Since the transmission rod 31 passes through the adjusting sleeve 45, the transmission rod 31 also drives the adjusting sleeve 45 to rotate. At this time, the transmission rod 31 acts as a fan blade to ventilate the inside of the municipal pipeline, resulting in high safety during dredging.

[0084] Then, the first guide sleeve 41 is locked. At this time, the drive motor 13 is controlled to continue rotating. Under the action of the spiral groove 33 and the protrusion 42, the transmission soft rod 31 extends into the municipal pipeline. When the cleaning head 35 is pressed against the inner wall of the pipeline, as the transmission soft rod 31 rotates, the cleaning head 35 performs circumferential scraping on the inner wall of the pipeline. Then, the adjusting sleeve 45 is controlled to swing. The adjusting sleeve 45 increases the angle between the transmission soft rod 31 and the second guide sleeve 43. At the same time, as the transmission soft rod 31 extends, the cleaning head 35 can move along the inner wall of the pipeline into the pipeline, resulting in a good sludge removal effect.

[0085] Furthermore, the telescopic adjustment mechanism 4 also includes: a swing frame 46, a rotating cylinder 47, a telescopic screw 48, a pull rod 49, a conical toothed groove 411, a bevel gear 410, a brake pad 412, a first syringe 413, and a connecting rod 414. The swing frame 46 is located at the bottom of the second guide sleeve 43. A rotating cylinder 47 is rotatably mounted inside the swing frame 46. A telescopic threaded hole is opened inside the rotating cylinder 47, and the telescopic screw 48 is threadedly connected inside the telescopic threaded hole. A pull rod 49 is hinged to the outside of the telescopic screw 48. The pull rod 49 and... The adjusting sleeve 45 is hinged together. The outer side of the first guide sleeve 41 is provided with a conical toothed groove 411. The outer side of the rotating cylinder 47 is provided with a bevel gear 410, which meshes with the conical toothed groove 411. The outer side of the support frame 21 is hinged with a brake pad 412. The outer side of the support frame 21 is equipped with a first syringe 413. The first syringe 413 is connected to an external high-pressure water pump through a water pipe. The telescopic end of the first syringe 413 is hinged with a connecting rod 414. The other end of the connecting rod 414 is hinged with the brake pad 412.

[0086] When dredging is required, water is supplied to the first syringe 413 via an external high-pressure water pump and water pipe. The telescopic end of the first syringe 413 extends, driving the connecting rod 414 to swing. The connecting rod 414 then drives the brake pad 412 to swing, clamping the first guide sleeve 41 and locking it. When it is necessary to control the drive motor 13 to rotate, the drive motor 13 causes the transmission flexible rod 31 to rotate. Under the action of the spiral groove 33 and the protrusion 42, the transmission flexible rod 31 extends into the municipal pipeline. At the same time, the transmission flexible rod 31 drives the second guide sleeve 43 to rotate, and the second guide sleeve 43 drives the swing... The frame 46 rotates, which drives the rotating drum 47 to rotate. The rotating drum 47 drives the bevel gear 410 to rotate. The bevel gear 410 rotates under the action of the conical tooth groove 411. The bevel gear 410 drives the rotating drum 47 to rotate. The rotating drum 47 drives the telescopic screw 48 to move through the telescopic threaded hole. The telescopic screw 48 drives the pull rod 49 to swing. The pull rod 49 drives the adjusting sleeve 45 to swing. The adjusting sleeve 45 drives the transmission soft rod 31 to swing, thereby increasing the angle between the transmission soft rod 31 and the second guide sleeve 43, so that the cleaning head 35 can move along the inner wall of the pipe. This can be achieved simply by rotating the transmission soft rod 31, and the structure is compact.

[0087] Furthermore, a swing frame 46 is hinged to the bottom of the second guide sleeve 43, and a torsion spring is provided at the hinge of the swing frame 46. A second syringe 415 is installed on the outside of the support frame 21. The second syringe 415 is connected to an external high-pressure water pump through a water pipe. A top ring 416 is sleeved on the outside of the first guide sleeve 41. The top ring 416 is connected to the telescopic end of the second syringe 415.

[0088] When there is a lot of silt on the inner wall of the pipe, a greater cleaning force is required. At this time, water is supplied to the second injector 415 through an external high-pressure water pump and water pipe. The telescopic end of the second injector 415 drives the top ring 416 to move closer to the adjusting sleeve 45. The top ring 416 drives the swing frame 46 to swing. The swing frame 46 drives the bevel gear 410 to move away from the conical tooth groove 411. At this time, when the transmission soft rod 31 continues to rotate, the adjusting sleeve 45 will not swing. At this time, the nozzle 34 swings relative to the cleaning head 35, and the outlet of the nozzle 34 faces the cleaning head 35. Under the action of high-pressure jet, the cleaning head 35 is pressed more tightly against the inner wall of the pipe. At the same time, the swing frame 46 drives the rotating drum 47. The rotating drum 47 drives the telescopic screw 48 to swing, which in turn drives the pull rod 49 to swing. The pull rod 49 then drives the adjusting sleeve 45 to swing. The adjusting sleeve 45 reduces the angle between the transmission soft rod 31 and the second guide sleeve 43, causing the transmission soft rod 31 to press back. The water flow ejected from the transmission soft rod 31 through the nozzle 34 changes from being angled towards the cleaning head 35 to being perpendicular to it. Therefore, the support force provided by the transmission soft rod 31 to the cleaning head 35 through water pressure increases, and the pressure provided by the cleaning head 35 to the inner wall of the pipe increases. This allows for the removal of more stubborn sludge, ensuring the sludge removal effect and making the device suitable for pipes with different levels of pollution.
