Description

Technical Field

[0001] This invention relates to the field of municipal cleaning equipment technology, specifically to a pipe cleaning device for municipal engineering road drainage. Background Technology

[0002] In municipal engineering, road drainage pipes are crucial facilities for sewage discharge, and their smooth operation directly affects a city's flood control and drainage capabilities. Over long periods of operation, silt, leaves, oil, and other contaminants accumulate, easily forming stubborn deposits on the inner walls of the pipes, affecting drainage efficiency and even causing blockages.

[0003] To address pipe blockages, current techniques often involve hand-held tools to clean the inner walls of pipes, removing contaminants and debris. However, stubborn deposits and grime are difficult to remove completely with these tools. To thoroughly clean the pipe interior, workers typically use water guns to rinse it. Specifically, workers stand outside the pipe, holding a water gun and aiming the jet at the remaining contaminants inside to flush them away.

[0004] However, this cleaning method not only wastes a large amount of water resources, failing to meet the current requirements for green, low-carbon, and water-saving urban development, but also suffers from limited water flow capacity, making it difficult to thoroughly remove stubborn deposits. Furthermore, the confined space and poor lighting inside municipal drainage pipes prevent personnel from entering to work, and relying solely on external operators with handheld water guns makes it difficult to aim the water flow at the dirt. Therefore, we propose a pipe cleaning device for municipal engineering road drainage to effectively address these shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a pipe cleaning device for municipal engineering road drainage, which solves the problems mentioned in the background art.

[0006] This invention is achieved through the following technical solution: a pipe cleaning device for municipal engineering road drainage, comprising:

[0007] A cleaning cylinder, one end of which is provided with a control rod for controlling the cleaning cylinder to extend into the pipe;

[0008] A retaining mechanism is disposed on the outer surface of the cleaning cylinder and is used to fit against the inner wall of the pipe to maintain the stability of the cleaning cylinder;

[0009] The cleaning mechanism includes a rotating sleeve rotatably fitted outside the cleaning cylinder, and a scraper connected to the outer surface of the rotating sleeve via an adjustment component.

[0010] A power mechanism, located inside the cleaning cylinder, is used to drive the rotating sleeve to rotate;

[0011] The cleaning cylinder has a scraping rope in the lower area. When the scraper rotates to the lower area of ​​the cleaning cylinder, the adjustment component can control the scraper to move closer to the cleaning cylinder so that the scraper and the scraping rope come into contact, thereby removing the dirt attached to the scraper surface.

[0012] Optionally, the cleaning cylinder includes a cylinder body, and a front end cap and a rear end cap threadedly fixed to the front and rear ends of the cylinder body. The control rod is fixedly connected to the rear end cap. The control rod has a tubular structure, and a wire hole is provided on the rear end cap. The power cord of the power mechanism extends outward through the wire hole and the control rod. The retaining mechanism includes four retaining rods, the length of which is telescopic, and the four retaining rods are X-shaped. The ends of the retaining rods are provided with wheels for abutting against the inner wall of the pipe.

[0013] Optionally, the power mechanism includes an electric motor, the output shaft of which is provided with a driving gear, and an adjustment hole is provided through the wall of the cleaning cylinder. A driven gear that meshes with the driving gear is provided at the adjustment hole. The driven gear is rotatably connected to the inner wall of the cleaning cylinder. The rotating sleeve and the inner wall of the cleaning cylinder are rotatably engaged by a bearing. The inner ring wall of the rotating sleeve is also provided with a gear ring, and the driven gear meshes with the gear ring.

[0014] Optionally, the adjusting assembly includes an adjusting sleeve distributed radially along the cleaning cylinder. A displacement block is movably disposed inside the adjusting sleeve, and a compression spring is disposed between the displacement block and the inner end of the adjusting sleeve. A guide rod is disposed between the scraper and the displacement block, and the guide rod movably passes through the outer end of the adjusting sleeve. Symmetrical fan-shaped plates are arranged on the front and rear sides of the rotating sleeve. Both fan-shaped plates are fixedly connected to the cleaning cylinder, and both ends of the scraping rope are connected to the two fan-shaped plates respectively. A wiring groove is formed on the facing surfaces of both fan-shaped plates. A wiring rod is provided at both ends of the displacement block for embedding into the wiring groove. When the scraper enters between the two fan-shaped plates, the wiring rod can automatically enter the wiring groove, and as the rotating sleeve continues to rotate, the scraper can move closer to the cleaning cylinder.

[0015] Optionally, both facing surfaces of the two sector plates are provided with wiring rails. The wiring rails are arc-shaped, and the center of the corresponding circle of the wiring rail coincides with the central axis of the cleaning cylinder. A slider is slidably provided inside the wiring rail, and the slider and the wiring rail slide in cooperation along the length of the wiring rail. The two ends of the scraping rope are respectively connected to the two sliders. One end of the slider and the wiring rail are connected by an elastic rope. When the wiring rod enters the end position of the wiring groove, the scraper can separate from the scraping rope.

[0016] Optionally, the slider is rotatably equipped with scraping gears, and the two ends of the scraping rope are respectively connected to the center positions of the two scraping gears; one of the guide rails is also provided with an arc-shaped rack distributed along its own length direction, and the scraping gears and the arc-shaped rack mesh with each other.

[0017] Compared with the prior art, the present invention provides a pipe cleaning device for municipal engineering road drainage, which has the following beneficial effects:

[0018] 1. This invention uses a cleaning cylinder inserted into the pipe and a scraper to scrape along the inner wall of the pipe to remove stubborn deposits. Compared with traditional techniques, this solution can not only thoroughly clean stubborn deposits, but also avoids wasting a lot of water resources.

[0019] 2. In the continuous rotation process of the scraper in this invention, each time the scraper rotates to the lower area of ​​the cleaning cylinder, the scraper will automatically make contact with the scraping rope to scrape off the dirt on the scraper, thus avoiding the accumulation of dirt on the scraper and the resulting decrease in cleaning ability;

[0020] 3. When the scraping rope moves with the scraper in this invention, it can rotate to increase the friction between itself and the scraper surface, thereby completely removing stubborn deposits. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 - Figure 9 This application proposes a pipe cleaning device for municipal engineering road drainage, including a cleaning cylinder 100, a holding mechanism 200, a cleaning mechanism 300, and a power mechanism 400. The cleaning cylinder 100 includes a cylinder body 101, and a front end cap 102 and a rear end cap 103 that are threadedly fixed to the front and rear ends of the cylinder body 101. One end of the cleaning cylinder 100 is provided with a control rod 500 for controlling the cleaning cylinder 100 to extend into the pipe. Specifically, the control rod 500 and the rear end cap 103 are fixedly connected.

[0033] like Figure 2 As shown, the retaining mechanism 200 is disposed on the outer surface of the cleaning cylinder 100 and is used to conform to the inner wall of the pipe to maintain the stability of the cleaning cylinder 100. Specifically, the retaining mechanism 200 includes four retaining rods 201, the length of which is telescopic, and the four retaining rods 201 are X-shaped. The ends of the retaining rods 201 are provided with wheels 202 for abutting against the inner wall of the pipe. Furthermore, the retaining rod 201 includes an outer rod body and an inner rod body. The inner rod body is embedded inside the outer rod body, and a locking bolt is threaded onto the outer rod body to fix the inner rod body and adjust the length of the retaining rod 201 to adapt to the inner diameter of the pipe. This four-legged mechanism can effectively maintain the stability of the cleaning cylinder 100 inside the pipe.

[0034] like Figure 3As shown, the cleaning mechanism 300 includes a rotating sleeve 301 rotatably sleeved outside the cleaning cylinder 100. The cleaning mechanism 300 also includes a scraper 302. The scraper 302 and the outer surface of the rotating sleeve 301 are connected by an adjusting component. Specifically, the rotating sleeve 301 and the cleaning cylinder 100 are rotatably connected by a bearing. The outer surface of the cleaning cylinder 100 is stepped. Under the constraint of the stepped wall of the cleaning cylinder 100 and the front cover 102, the rotating sleeve 301 can maintain its stability in the axial direction.

[0035] like Figure 3 As shown, a power mechanism 400 is located inside the cleaning cylinder 100 and is used to drive the rotating sleeve 301 to rotate. The power mechanism 400 includes a motor 401, the output shaft of which is equipped with a driving gear 402. An adjustment hole is provided through the cylinder wall of the cleaning cylinder 100, and a driven gear 403 that meshes with the driving gear 402 is provided at the adjustment hole. The driven gear 403 is rotatably connected to the inner wall of the cleaning cylinder 100. The rotating sleeve 301 and the inner wall of the cleaning cylinder 100 are rotatably engaged by a bearing. The inner ring wall of the rotating sleeve 301 is also provided with a gear ring 303, which meshes with the driven gear 403. Therefore, by the action of the motor 401, the rotation of the rotating sleeve 301 can be controlled, thereby controlling the scraper 302 to scrape against the inner wall of the pipe to remove dirt adhering to the inner wall of the pipe.

[0036] In addition, the control rod 500 has a tubular structure, and a wire hole is provided on the rear end cover 103. The power cord of the motor 401 extends outward through the wire hole and the control rod 500. In this embodiment, during implementation, the staff standing outside can hold the control rod 500 to control the cleaning cylinder 100 to move inside the pipe, thereby cleaning various parts of the pipe. It is worth mentioning that, in order to facilitate the carrying of this device, the control rod 500 can be a telescopic rod, such as a structure similar to a fishing rod, to reduce the storage space of this device. Since the space inside the pipe is small and humid, it is inconvenient for staff to enter. Therefore, in this embodiment, the staff can stand outside the pipe and then hold the control rod 500 to control the cleaning cylinder 100 to move slowly inside the pipe. This is not only labor-saving and convenient, but also avoids water waste.

[0037] The cleaning cylinder 100 has a scraping rope 600 in its lower region. When the scraper 302 rotates to the lower region of the cleaning cylinder 100, the adjusting component can control the scraper 302 to move closer to the cleaning cylinder 100 so that the scraper 302 and the scraping rope 600 come into contact, thereby removing the dirt attached to the surface of the scraper 302. Specifically, the adjusting component includes an adjusting sleeve 304, which is radially distributed along the cleaning cylinder 100. A displacement block 305 is movably provided inside the adjusting sleeve 304, and a compression spring 306 is provided between the displacement block 305 and the inner end of the adjusting sleeve 304. A guide rod 307 is provided between the scraper 302 and the displacement block 305, and the guide rod 307 movably passes through the outer end of the adjusting sleeve 304. The adjusting sleeve 304 is a rectangular tubular structure, welded and fixed to the outer surface of the rotating sleeve 301. The guide rod 307 is axially distributed along the radial direction of the cleaning cylinder 100. The displacement block 305 is elastically connected to the adjusting sleeve 304 by a compression spring 306. Notably, the outer end cap of the adjusting sleeve 304 has a shaft hole for the guide rod 307 to pass through, and the outer end cap and the main body of the adjusting sleeve are fixed by bolts for easy disassembly.

[0038] It is worth mentioning that the scraper 302 is a thin aluminum alloy plate, which abuts against the inner wall of the pipe during the cleaning process through the thrust provided by the compression spring 306. Specifically, in this embodiment, since the rotating sleeve 301 always rotates to one side, the dirt on the inner wall of the pipe is always located on one side of the scraper 302; the side with the dirt attached is the side of the scraper 302 that contacts the scraping rope 600. It should also be noted that in practical application, the scraping rope 600 must be kept directly below the cleaning cylinder 100 to ensure that when the scraper 302 and the scraping rope 600 come into contact, the scraped dirt is located at the bottom of the pipe for subsequent cleaning.

[0039] In this embodiment, symmetrical sector plates 601 are provided on the front and rear sides of the rotating sleeve 301. Both sector plates 601 are fixedly connected to the cleaning cylinder 100. The two ends of the scraping rope 600 are respectively connected to the two sector plates 601. The facing surfaces of the two sector plates 601 are provided with wiring grooves 602. Both ends of the displacement block 305 are provided with wiring rods 308 for embedding in the wiring grooves 602. When the scraper 302 enters between the two sector plates 601, the wiring rods 308 can automatically enter the wiring grooves 602. As the rotating sleeve 301 continues to rotate, the scraper 302 can move closer to the cleaning cylinder 100. The two sector plates 601 are welded and fixed to the cylinder body 101 and the front end cover 102 respectively. The end of the sector plate 601 has a gap with the inner wall of the pipe. This gap should not be less than 5 cm. The purpose is to prevent the sector plate 601 from directly contacting the dirt on the inner wall of the pipe. The cable tray 602 is arc-shaped, and the difference between the distance between the two ends of the cable tray 602 and the central axis of the cleaning cylinder 100 is greater than the gap between the end of the fan-shaped plate 601 and the inner wall of the pipe.

[0040] It should be noted that both sides of the adjusting sleeve 304 have slots for the cable guide rod 308 to pass through. When the scraper 302 is not subjected to radial external force, the cable guide rod 308 can automatically enter the cable guide groove 602. Furthermore, one end of the cable guide groove 602 is flared to allow the cable guide rod 308 to enter the cable guide groove 602 more smoothly. After the cable guide rod 308 enters the cable guide groove 602, the displacement block 305 can carry the scraper 302 to automatically move towards the side closer to the center of the cleaning cylinder 100.

[0041] Furthermore, both facing surfaces of the two sector plates 601 are provided with a guide rail 603. The guide rail 603 has an arc-shaped hollow structure, and the center of the guide rail 603 coincides with the central axis of the cleaning cylinder 100. A slider 604 is slidably provided inside the guide rail 603, and the slider 604 and the guide rail 603 slide together along the length of the guide rail 603. The two ends of the scraping rope 600 are respectively connected to the two sliders 604. One end of the slider 604 and the guide rail 603 are connected by an elastic rope 605. When the guide rod 308 enters the end position of the guide groove 602, the scraper 302 can separate from the scraping rope 600. That is, the slider 604 is elastically connected inside the cable guide 603, and in the initial state, the scraping rope 600 is located on one side of the flared end of the cable groove 602; when the scraper 302 enters between the two fan-shaped plates 601, the scraper 302 can push the scraping rope 600 to move synchronously and continuously stretch the elastic rope 605; at the same time, the distance between the scraping rope 600 and the cleaning cylinder 100 remains unchanged, while the scraper 302 gradually moves closer to the cleaning cylinder 100. Therefore, a radial relative displacement can be generated between the scraper 302 and the scraping rope 600, thereby using the scraping rope 600 to scrape off the dirt on the surface of the scraper 302.

[0042] In summary, in this embodiment, during specific application, the cleaning cylinder 100 moves slowly inside the pipe by holding the control lever 500, and the scraper 302 moves in a circular motion relative to the cleaning cylinder 100, thereby scraping off the dirt on the inner wall of the pipe. When the scraper 302 moves to the bottom position, the scraper 302 contacts the scraping rope 600 and pushes the scraping rope 600 to move synchronously; during this process, the scraper 302 moves closer to the cleaning cylinder 100, and the scraper 302 and the scraping rope 600 slide relative to each other, ultimately allowing the scraping rope 600 to scrape off the dirt attached to the scraper 302. The scraped-off dirt falls to the bottom area of ​​the pipe. After the cleaning work of this device is completed, a large amount of dirt will accumulate in the bottom area of ​​the pipe, which can then be flushed with water, thus saving a lot of water resources.

[0043] In another embodiment of this application, a scraping gear 606 is rotatably mounted on the slider 604, and the two ends of the scraping rope 600 are respectively connected to the center positions of the two scraping gears 606; one of the wiring rails 603 also has an arc-shaped rack 607 distributed along its own length direction inside, and the scraping gear 606 and the arc-shaped rack 607 mesh with each other. At the same time, the wiring rail 603 also has a cover plate on the outside, and the cover plate has a threading slot for the scraping rope 600 to pass through. When the slider 604 slides along the wiring rail 603, the scraping gear 606 can rotate continuously, thereby driving the scraping rope 600 to rotate.

[0044] In other words, when the scraper 302 and the scraping rope 600 are in contact, the scraping rope 600 is always rotating. The scraping rope 600 is made of steel wire rope with a rough surface and is always under tension. When the scraping rope 600 rotates, the friction between the scraping rope 600 and the surface of the scraper 302 is further increased, which is more conducive to removing stubborn dirt from the scraper 302 and improving the cleaning effect.
