Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a high-efficiency pipeline cleaning device with rotating jet flow. Background Technology

[0002] In industrial production, urban infrastructure construction, and various fluid transportation systems, pipelines serve as critical transport channels, and their internal cleanliness is crucial for the normal operation of the system and the assurance of fluid quality. Over time, dirt, rust, deposits, and other impurities gradually accumulate on the inner walls of pipelines. These impurities not only reduce the effective flow area of ​​the pipeline and increase fluid transport resistance, leading to increased energy consumption, but can also breed bacteria, corrode the pipeline, and even cause safety accidents such as pipeline blockages and leaks, seriously affecting production efficiency and equipment lifespan. Therefore, regularly conducting efficient and thorough cleaning of pipelines is a necessary measure to ensure the stable operation of pipeline systems and extend their service life.

[0003] Currently, there are various pipe cleaning devices on the market, but these existing technologies all have certain limitations in practical applications.

[0004] A common type of pipe cleaning device uses a built-in motor to drive the device within the pipe, rotating the nozzles for omnidirectional cleaning. However, this design places extremely high demands on the motor's sealing. Due to the complex environment inside pipes, which may contain high pressure, humidity, and corrosive media, if the motor seal fails, moisture and impurities will penetrate the motor, causing damage and affecting the normal operation of the entire cleaning device. Furthermore, the built-in motor design makes the overall structure and installation more complex, requiring careful arrangement of the connections and transmission mechanisms between the motor and other components. This not only increases manufacturing difficulty but also significantly raises manufacturing costs.

[0005] Another method of pipe cleaning relies on a straight rod to pull or push the cleaning device from the outside of the pipe. This method has the advantage of relatively simple structure and low cost. However, in actual use, when encountering curved pipes, the rigidity of the straight rod makes it difficult to flexibly adapt to the pipe's curvature. Operators need to spend a lot of time and effort adjusting the angle and position of the straight rod to ensure the cleaning device can smoothly pass through the curved pipe. This greatly increases the difficulty and complexity of operation, reduces cleaning efficiency, and in some cases, due to the excessive curvature of the pipe, the straight rod pulling method may not be able to complete the cleaning task at all. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the prior art by providing a high-efficiency pipe cleaning device with rotating jet flow, which realizes the rotating spray cleaning function of the nozzle, simplifies the overall structure of the device, and significantly reduces manufacturing costs; the rotating spray cleaning mechanism moves axially back and forth inside the pipe, and is not limited by the degree of pipe curvature.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A high-efficiency pipe cleaning device with rotating jet flow includes a rotating spraying mechanism. One end of the rotating spraying mechanism is connected to a first guide pipe, and the other end is connected to a second guide pipe. The rotating spraying mechanism includes a nozzle, a central pipe, and a rotating joint pipe. The peripheral wall of the nozzle is provided with a plurality of spray holes. One end of the nozzle is closed and connected to the first guide pipe, and the other end is open and connected to one end of the central pipe. The other end of the central pipe is connected to one end of the rotating joint pipe, and the other end of the rotating joint pipe is connected to the second guide pipe. The rotating joint pipe includes a first section pipe and a second section pipe rotatably connected to the first section pipe. The first section pipe is connected to the central pipe, and the second section pipe is connected to the second guide pipe. The other end of the first guide pipe is connected to a rotating drive device.

[0009] Furthermore, the closed end of the nozzle is provided with a column, the end of the column is provided with a T-shaped groove, the end of the first guide tube is provided with a T-shaped block, and the T-shaped block is radially inserted into the T-shaped groove.

[0010] Furthermore, the nozzle is threadedly connected to the central tube, the central tube is threadedly connected to the first section tube, and the second section tube is threadedly connected to the second guide tube.

[0011] Furthermore, the central tube is connected to a retainer, the retainer including a sleeve, several support plates, and several guide wheels; the sleeve is rotatably fitted on the outside of the center, the several support plates are circumferentially distributed on the periphery of the sleeve, each support plate extends axially, and at least two guide wheels are connected to the side of each support plate away from the sleeve.

[0012] Furthermore, both ends of the central tube are connected to the sleeve via bearings, with the outer ring of the bearing connected to the sleeve and the inner ring of the bearing connected to the central tube.

[0013] Furthermore, a dust cover is threadedly connected to the side of the bearing of the central tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The design of the built-in motor was abandoned. Instead, an external rotary drive device was used to drive the rotary spraying mechanism to rotate through the first guide tube, so as to realize the rotary spraying function of the nozzle. This effectively reduced the dependence on the motor's sealing performance and avoided equipment damage caused by motor seal failure. At the same time, it simplified the overall structure of the device and significantly reduced the manufacturing cost.

[0016] The rotary spraying mechanism sprays high-pressure water from multiple nozzles on the sidewall of the nozzle to form a multi-directional high-pressure water jet that initially flushes the inner wall of the pipe. At the same time, the rotary drive device drives the nozzle to rotate, forming a rotary jet. The rotary jet can flush the inner wall of the pipe from multiple angles in an all-round and high-intensity manner, which significantly enhances the cleaning effect, effectively removes stubborn stains from the inner wall of the pipe, and improves the quality and efficiency of pipe cleaning.

[0017] By setting a first guide pipe and a second guide pipe, after the rotary spraying mechanism is placed into the pipe, the first guide pipe extends from one end of the pipe and connects to the rotary drive device, and the second guide pipe extends from the other end. During the cleaning process, the rotary spraying mechanism can move axially back and forth in the pipe by simply dragging the first guide pipe or the second guide pipe manually or automatically, without being limited by the degree of pipe bending.

[0018] The nozzle has a closed end with a column, and the end of the column has a T-slot. The end of the first guide tube has a T-block. The T-block is radially inserted into the T-slot. When the rotary drive device drives the first guide tube to rotate, the rotational power of the first guide tube can be smoothly transmitted to the nozzle due to the cooperation between the T-block and the T-slot, thereby driving the nozzle to rotate together. The structure is simple and easy to assemble, which can effectively improve the assembly efficiency of the device and reduce production costs. Attached Figure Description

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Currently, there are various pipe cleaning devices on the market, but these existing technologies all have certain limitations in practical applications.

[0029] A common type of pipe cleaning device uses a built-in motor to drive the device within the pipe, rotating the nozzles for omnidirectional cleaning. However, this design places extremely high demands on the motor's sealing. Due to the complex environment inside pipes, which may contain high pressure, humidity, and corrosive media, if the motor seal fails, moisture and impurities will penetrate the motor, causing damage and affecting the normal operation of the entire cleaning device. Furthermore, the built-in motor design makes the overall structure and installation more complex, requiring careful arrangement of the connections and transmission mechanisms between the motor and other components. This not only increases manufacturing difficulty but also significantly raises manufacturing costs.

[0030] Another method of pipe cleaning relies on a straight rod to pull or push the cleaning device from the outside of the pipe. This method has the advantage of relatively simple structure and low cost. However, in actual use, when encountering curved pipes, the rigidity of the straight rod makes it difficult to flexibly adapt to the pipe's curvature. Operators need to spend a lot of time and effort adjusting the angle and position of the straight rod to ensure the cleaning device can smoothly pass through the curved pipe. This greatly increases the difficulty and complexity of operation, reduces cleaning efficiency, and in some cases, due to the excessive curvature of the pipe, the straight rod pulling method may not be able to complete the cleaning task at all.

[0031] To address the above technical problems, this application provides a high-efficiency pipe cleaning device with rotating jet flow, including a rotating spraying mechanism 1. One end of the rotating spraying mechanism 1 is connected to a first guide pipe 2, and the other end is connected to a second guide pipe 3. The rotating spraying mechanism 1 includes a nozzle 11, a central pipe 12, and a rotary joint pipe 13. The peripheral sidewall of the nozzle 11 is provided with a plurality of spray holes. One end of the nozzle 11 is closed and connected to the first guide pipe 2, and the other end is open and connected to one end of the central pipe 12. The other end of the central pipe 12 is connected to one end of the rotary joint pipe 13, and the other end of the rotary joint pipe 13 is connected to the second guide pipe 3. The rotary joint pipe 13 includes a first section pipe 131 and a second section pipe 132 rotatably connected to the first section pipe 131. The first section pipe 131 is connected to the central pipe 12, and the second section pipe 132 is connected to the second guide pipe 3. The other end of the first guide pipe 2 is connected to a rotating drive device.

[0032] The rotary spraying mechanism 1 is placed inside the pipe to be cleaned. The first guide pipe 2 extends from one end of the pipe, and the second guide pipe 3 extends from the other end of the pipe. One end of the first guide pipe 2 is connected to a rotary drive device to provide rotational power.

[0033] High-pressure water enters the rotary joint pipe 13 through the second guide pipe 3, and then sequentially enters the central pipe 12 and the nozzle 11. The peripheral wall of the nozzle 11 is provided with several spray holes. High-pressure water is sprayed out from these spray holes to form a multi-directional high-pressure water jet, which flushes the inner wall of the pipe, thereby removing the dirt from the inner wall of the pipe.

[0034] After the rotary drive device is started, it drives the first guide pipe 2, the nozzle 11, the central pipe 12, and the first section 131 of the rotary joint pipe 13 to rotate together. Since the rotary joint pipe 13 includes the first section 131 and the second section 132 that are rotatably connected, and the second section 132 is connected to the second guide pipe 3, the second section 132 and the second guide pipe 3 remain stationary. This allows the nozzle 11 to rotate as it enters the high-pressure water, thus forming a rotating jet stream and further enhancing the cleaning effect.

[0035] As the rotating jet stream is formed, the first guide pipe 2 or the second guide pipe 3 is manually or automatically dragged, causing the rotating jet cleaning mechanism 1 to move axially back and forth inside the pipe. In this way, the rotating jet stream can cover all areas of the pipe's inner wall, achieving full coverage cleaning of the entire pipe's inner wall.

[0036] The pipe cleaning device in this embodiment features a unique rotary joint pipe 13 design. High-pressure water enters the rotary joint pipe 13 through the second guide pipe 3, then sequentially enters the central pipe 12 and the nozzle 11. It is then ejected from multiple nozzle holes on the periphery of the nozzle 11, forming a multi-directional high-pressure water jet to initially flush the inner wall of the pipe. Simultaneously, a rotary drive device activates, causing the first guide pipe 2, nozzle 11, central pipe 12, and the first section 131 of the rotary joint pipe 13 to rotate together. The second section 132 of the rotary joint pipe 13 is connected to the second guide pipe 3 and remains stationary, ensuring that the nozzle 11 rotates synchronously during the high-pressure water ejection process, forming a rotating jet. This structure eliminates the need for a built-in motor, achieving the rotating spraying function of the nozzle 11 through an external rotary drive device. This effectively reduces reliance on motor sealing, simplifies the overall structure of the device, and significantly reduces manufacturing costs.

[0037] The rotating jet can thoroughly and intensely flush the inner wall of the pipe from multiple angles, significantly enhancing the cleaning effect, effectively removing stubborn stains from the inner wall of the pipe, and improving the quality and efficiency of pipe cleaning.

[0038] With the first guide pipe 2 and the second guide pipe 3 installed, after the rotary spraying mechanism 1 is placed in the pipe, the first guide pipe 2 extends from one end of the pipe and connects to the rotary drive device, while the second guide pipe 3 extends from the other end. During the cleaning process, the rotary spraying mechanism 1 can move axially back and forth within the pipe simply by manually or automatically dragging the first guide pipe 2 or the second guide pipe 3, without being limited by the curvature of the pipe. This simple and convenient operation greatly improves the efficiency and flexibility of the cleaning operation.

[0039] Optionally, the first guide pipe 2 and the second guide pipe 3 are high-pressure rubber-steel wire hoses. They have excellent flexibility and can bend freely at pipe bends without affecting the normal delivery of high-pressure water due to pipe bending, ensuring stable operation of the device in various complex pipeline environments.

[0040] Optionally, the rotary drive unit is a lithium battery-powered electric drill. Operators can easily hold and operate it, allowing for flexible movement at the pipe cleaning site. By turning on the lithium battery-powered electric drill and pulling it, the rotary spraying mechanism can be easily driven to rotate and move axially simultaneously, achieving efficient cleaning operations.

[0041] In some embodiments, the closed end of the nozzle 11 is provided with a column 111, the end of the column 111 is provided with a T-groove 112, and the end of the first guide tube 2 is provided with a T-block 21, which is radially inserted into the T-groove 112.

[0042] When assembling the pipeline cleaning device, the T-shaped block 21 at the end of the first guide pipe 2 is radially inserted into the T-shaped groove 112 at the end of the closed end column 111 of the nozzle 11. This simple structure is easy to assemble, effectively improving assembly efficiency and reducing production costs. When the rotary drive device rotates the first guide pipe 2, the rotational power of the first guide pipe 2 is smoothly transmitted to the nozzle 11 due to the cooperation between the T-shaped block 21 and the T-shaped groove 112, thus causing the nozzle 11 to rotate as well.

[0043] In some embodiments, the nozzle 11 is threadedly connected to the central tube 12, the central tube 12 is threadedly connected to the first section tube 131, and the second section tube 132 is threadedly connected to the second guide tube 3.

[0044] Threaded connections are simple to operate, offer high connection strength and sealing performance, and effectively prevent high-pressure water leakage at the joints of components. The rotary drive unit starts, causing the rotary spraying mechanism 1 to rotate in the direction of thread tightening. Since the components are connected by threads, the friction and interaction forces between the threads further enhance the tightness of the connection when rotating in the direction of thread tightening, making the connection between components more stable.

[0045] In some embodiments, the central tube 12 is connected to a retainer 4, the retainer 4 including a sleeve 41, a plurality of support plates 42, and a plurality of guide wheels 43; the sleeve 41 is rotatably sleeved on the outside of the central tube 12, the plurality of support plates 42 are circumferentially distributed on the periphery of the sleeve 41, each support plate 42 extends axially, and at least two guide wheels 43 are connected to the side of each support plate 42 away from the sleeve 41.

[0046] When the rotary drive device is started, the rotary spraying mechanism 1 begins to rotate inside the pipe. At this time, because the sleeve 41 of the retainer 4 is rotatably connected to the central tube 12, the sleeve 41 does not rotate with the rotary spraying mechanism 1, but it will move axially within the pipe along with the rotary spraying mechanism 1. During the axial movement of the device, the guide wheels 43 connected to the side of each support plate 42 on the retainer 4 away from the sleeve 41 are in close contact with the inner wall of the pipe. As the device moves, the guide wheels 43 roll along the inner wall of the pipe, reducing the friction between the device and the inner wall of the pipe. At the same time, the guide wheels 43 transmit the supporting force to the sleeve 41 through the support plate 42, thereby supporting and positioning the central tube 12, ensuring that the central tube 12 and the entire rotary spraying mechanism 1 always remain in a centered position within the pipe, so that the rotating jet sprayed from the nozzle 11 can evenly cover all areas of the inner wall of the pipe.

[0047] In some embodiments, the two ends of the central tube 12 are connected to the sleeve 41 via bearings 15, the outer ring of the bearing 15 is connected to the sleeve 41, and the inner ring of the bearing 15 is connected to the central tube 12.

[0048] Due to the presence of bearing 15, relative rotation can be achieved between the central tube 12 and the sleeve 41; that is, the central tube 12 rotates, while the sleeve 41 does not rotate accordingly. Simultaneously, when the device undergoes axial movement, the sleeve 41 will follow the central tube 12 in axial displacement within the pipe.

[0049] In some embodiments, the central tube 12 is connected to a dust cover 14 by threads on the side of the bearing 15.

[0050] Because the internal environment of the pipeline is complex and contains dust, impurities, and moisture, the dust cover 14 can prevent these external substances from entering the area where the bearing 15 is located, thus preventing impurities from entering the bearing 15 and affecting its normal rotation. This ensures smooth relative rotation between the central tube 12 and the sleeve 41, guarantees the normal rotation and axial movement of the rotary spray cleaning mechanism 1, and allows the rotary jet sprayed from the nozzle 11 to continuously and evenly cover the inner wall of the pipeline for cleaning.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
