Description

Technical Field

[0001] This invention belongs to the field of condenser copper tube cleaning technology, specifically relating to a pipeline cleaning device. Background Technology

[0002] The condenser is a key heat exchange device in the circulating cooling water system of a thermal power plant, containing hundreds or even thousands of copper tubes densely arranged inside. During long-term operation, calcium and magnesium ions, suspended particulate matter, and microbial sludge from the cooling water tend to gradually deposit on the inner walls of the copper tubes, forming a fouling layer with extremely poor thermal conductivity. This not only leads to a significant decrease in condenser vacuum and heat exchange efficiency, increasing unit energy consumption, but may also cause under-deposit corrosion, resulting in copper tube perforation and leakage, seriously threatening the safe and stable operation of the unit.

[0003] Therefore, regular cleaning of the inside of copper tubes is essential for restoring heat exchange performance and extending equipment life. Currently, the industry commonly uses manual cleaning of condenser copper tubes, where operators use a cleaning rod with a brush or spray nozzle attached to each tube to rinse or scrub it. However, this manual method has a significant technical bottleneck: the cleaning depth is difficult to control precisely, easily creating blind spots and making it difficult to ensure uniform cleaning quality along the entire length of each copper tube. This ultimately leads to a continuous deterioration of the heat exchange performance of the entire condenser, forcing more frequent shutdowns for cleaning and resulting in high maintenance costs. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of the present invention provide a pipeline cleaning device that can automatically extend and retract inside the pipeline, precisely control the cleaning depth, and reduce blind spots in the cleaning process.

[0005] The pipeline cleaning device of this invention includes a housing, a moving component, and a cleaning component. The moving component is disposed in the housing and includes a moving part and a telescopic rod. One end of the telescopic rod is connected to the moving part, and the moving part drives the telescopic rod to perform linear reciprocating motion. The cleaning component includes a nozzle for spraying cleaning fluid, and the nozzle is disposed at the other end of the telescopic rod. The moving part drives the telescopic rod to extend out of the housing, and when the telescopic rod extends, it drives the nozzle into the pipeline, whereby the nozzle flushes the inner wall of the pipeline.

[0006] The pipeline cleaning device of this invention uses a moving component to drive a telescopic rod in a linear reciprocating motion. The telescopic rod drives the nozzle to extend into the pipeline for rinsing, achieving precise mechanical control of the cleaning depth. Compared to the manual method of pushing the cleaning rod by feel, the driving and guiding effect provided by the moving component ensures that the nozzle accurately reaches the predetermined position deep within the pipeline, eliminating cleaning blind spots and maintaining uniform cleaning quality throughout the entire length of the pipeline, thus improving the reliability and efficiency of the cleaning operation.

[0007] In some embodiments, the moving component includes a threaded rod and a threaded sleeve. The threaded rod is rotatably disposed in the housing, and the threaded sleeve is threadedly disposed on the threaded rod. The threaded sleeve is slidably connected to the inner wall of the housing. The telescopic rod is rotatably connected to the threaded sleeve and is slidably disposed on the threaded rod, so that when the threaded rod rotates, it drives the telescopic rod to rotate.

The plurality of slide rails correspond one-to-one with the plurality of sliders, and the sliders are slidably connected to the slide rails.

[0009] In some embodiments, the moving component further includes a motor, a driving gear, and a driven gear. The motor is disposed on the inner wall of the housing, and the output end of the motor is connected to the driving gear.

[0011] In some embodiments, the cleaning assembly further includes a mounting block and a spiral tab. The mounting block is disposed between the nozzle and the telescopic rod, and the spiral tab is spirally wound around the mounting block. The spiral tab is used to scrape off dirt from the inner wall of the pipeline when the nozzle rotates.

[0012] In some embodiments, the cleaning assembly further includes bristles disposed on the outer wall of the telescopic rod, the bristles being used to scrub the inner wall of the pipe when the telescopic rod moves.

[0013] In some embodiments, the cleaning assembly further includes a liquid supply component, which includes an extraction pump, a water supply pipe, and a water guide pipe. The extraction pump is disposed in the housing, one end of which is connected to the water supply pipe, and the other end of which is connected to the nozzle through the water guide pipe for supplying cleaning fluid to the nozzle.

[0014] In some embodiments, the housing includes heat dissipation holes formed on the housing, one end of the heat dissipation holes communicating with the interior of the housing, and the other end of the heat dissipation holes communicating with the outside.

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1-6 As shown, the pipeline cleaning device of this embodiment includes a housing 1, a motion component 2, and a cleaning component 3. The motion component 2 is disposed within the housing 1 and includes a moving element 21 and a telescopic rod 22. One end of the telescopic rod 22 is connected to the moving element 21, and the moving element 21 drives the telescopic rod 22 to perform linear reciprocating motion. The cleaning component 3 includes a nozzle 31, which sprays cleaning fluid and is disposed at the other end of the telescopic rod 22. Specifically, the moving element 21 drives the telescopic rod 22 to extend out of the housing 1. When the telescopic rod 22 extends, it drives the nozzle 31 into the pipeline, where the nozzle 31 flushes the inner wall of the pipeline.

[0026] The pipeline cleaning device of this invention uses a moving component to drive a telescopic rod in a linear reciprocating motion. The telescopic rod drives the nozzle to extend into the pipeline for rinsing, achieving precise mechanical control of the cleaning depth. Compared to the manual method of pushing the cleaning rod by feel, the driving and guiding effect provided by the moving component ensures that the nozzle accurately reaches the predetermined position deep within the pipeline, eliminating cleaning blind spots and maintaining uniform cleaning quality throughout the entire length of the pipeline, thus improving the reliability and efficiency of the cleaning operation.

[0027] Specifically, the housing 1 serves as the overall support structure of the device, providing an installation foundation and protective space for the moving component 2 and the cleaning component 3. After receiving power, the moving component 21 drives the telescopic rod 22 to reciprocate linearly along its own axis. The end of the telescopic rod 22 extending from the housing 1 drives the nozzle 31 into the pipeline to be cleaned. The nozzle 31 sprays high-pressure cleaning fluid into the pipeline, rinsing and removing dirt adhering to the pipeline wall. By controlling the driving stroke of the moving component 21, the depth of the nozzle 31 extending into the pipeline can be precisely adjusted, thus adapting to the cleaning needs of pipelines of different lengths and specifications.

[0028] Furthermore, the pipeline cleaning device can be used for cleaning copper tubes in condensers of thermal power plants. A handle 5 can be installed on the casing 1, forming a gun-shaped structure with the casing 1, facilitating one-handed grip and operation by the operator. The casing 1 can be made of engineering plastics or lightweight alloys to reduce the overall weight and lower the labor intensity of the operation.

[0029] In some embodiments, the moving component 21 includes a threaded rod 211 and a threaded sleeve 212. The threaded rod 211 is rotatably disposed in the housing 1, and the threaded sleeve 212 is threadedly disposed on the threaded rod 211. The threaded sleeve 212 is slidably connected to the inner wall of the housing 1. The telescopic rod 22 is rotatably connected to the threaded sleeve 212, and the telescopic rod 22 is slidably disposed on the threaded rod 211 so that when the threaded rod 211 rotates, it drives the telescopic rod 22 to rotate.

[0030] This invention utilizes a threaded engagement structure between a threaded rod and a threaded sleeve to convert rotational motion into linear reciprocating motion and rotational motion of the telescopic rod. The threaded drive features self-locking and precise displacement control; for each rotation of the threaded rod, the telescopic rod moves axially by one thread pitch. By controlling the number of rotations of the threaded rod, precise adjustment of the nozzle insertion depth can be achieved. Simultaneously, the threaded sleeve's sliding connection with the housing restricts its circumferential rotation, allowing it to move only axially, thus ensuring the stability and reliability of the transmission path.

[0031] Specifically, the two ends of the threaded rod 211 are rotatably supported on the inner wall of the housing 1 by bearings, and the axial direction of the threaded rod 211 is consistent with the axial direction of the telescopic rod 22. The inner hole of the threaded sleeve 212 is machined with an internal thread that matches the external thread of the threaded rod 211. The threaded rod 211 passes through the threaded sleeve 212 and is screwed into it. When the threaded rod 211 rotates, the sliding connection between the threaded sleeve 212 and the inner wall of the housing 1 restricts its degree of freedom of rotation. The threaded sleeve 212 can only move along the axial direction of the threaded rod 211, thereby driving the telescopic rod 22 to perform linear reciprocating motion. At the same time, the telescopic rod 22 is rotatably connected to the threaded sleeve 212, so that the telescopic rod 22 can also rotate relative to the threaded sleeve 212 while moving linearly, thereby driving the nozzle 31 to rotate and rinse within the pipeline.

[0032] Furthermore, the thread type of the threaded rod 211 and the threaded sleeve 212 can be either trapezoidal or rectangular to withstand larger axial loads and improve transmission efficiency. The pitch of the threaded rod 211 can be selected according to the requirements of cleaning depth control accuracy. The smaller the pitch, the smaller the axial displacement per unit number of rotations, and the higher the depth control accuracy.

[0033] In some embodiments, the moving part 21 further includes a plurality of sliders 213 and a plurality of slide rails 214. The plurality of sliders 213 are spaced apart on the threaded sleeve 212 along the circumferential direction, and the plurality of slide rails 214 are spaced apart on the inner wall of the housing 1 along the circumferential direction. The plurality of slide rails 214 correspond one-to-one with the plurality of sliders 213, and the sliders 213 and slide rails 214 are slidably connected.

[0034] This invention provides stable axial guidance and reliable circumferential positioning for the threaded sleeve through the cooperation structure of the slider and the slide rail. Multiple sliders are spaced apart along the circumference, ensuring uniform force distribution on the threaded sleeve during movement, preventing skewing and jamming, and ensuring smooth and stable extension of the telescopic rod. Simultaneously, the precise fit between the slider and the slide rail effectively controls the radial runout of the nozzle at the end of the telescopic rod, improving the nozzle's alignment accuracy within the pipeline and preventing abnormal scraping between the nozzle and the pipe wall.

[0035] Specifically, the slide rail 214 extends along the axial direction of the threaded rod 211, and its length is determined based on the maximum stroke of the telescopic rod 22. The slider 213 can be fixed to the outer circumference of the threaded sleeve 212 by screws or integral molding. The cross-sectional shape of the slider 213 matches the cross-sectional shape of the slide rail 214, and the cross-sectional shape can be rectangular, trapezoidal, or dovetail-shaped. The number of sliders 213 can be two, three, or four, evenly distributed along the circumference of the threaded sleeve 212.

[0036] Furthermore, a wear-resistant coating or a lubricating liner may be provided on the surface of the slider 213 or the sliding surface of the slide rail 214 to reduce sliding friction resistance and extend service life.

[0037] In some embodiments, the moving part 21 further includes a motor 215, a driving gear 216 and a driven gear 217. The motor 215 is disposed on the inner wall of the housing 1. The output end of the motor 215 is connected to the driving gear 216. The driven gear 217 is fixedly sleeved on the threaded rod 211. The driving gear 216 meshes with the driven gear 217.

[0038] This invention provides a controllable rotational power source for the threaded rod through the cooperation of a motor and a gear transmission mechanism. The motor transmits power to the threaded rod via the meshing of a driving gear and a driven gear, achieving electric drive for the linear motion of the telescopic rod. Operators no longer need to manually push or rotate the cleaning rod, significantly reducing labor intensity and improving work efficiency. Simultaneously, the stable transmission ratio of the gear transmission, combined with the motor's speed control, allows for precise adjustment of the telescopic rod's movement speed.

[0039] Specifically, motor 215 can be a stepper motor or a servo motor to achieve precise control of rotation angle and speed. Motor 215 is fixed to the inner wall of housing 1 by a mounting bracket, and its output shaft is connected to drive gear 216 via a key connection or coupling. Driven gear 217 is fixedly sleeved on one end of threaded rod 211 via a key connection or interference fit. The gear ratio between drive gear 216 and driven gear 217 can be designed according to the required speed and torque, and the gear type can be spur gear or helical gear.

[0040] Furthermore, the motor 215 can be a closed-loop control motor with encoder feedback. The control system monitors the motor's rotation angle in real time, thereby accurately calculating the extension length of the telescopic rod 22 and achieving closed-loop control of the cleaning depth. When the number of teeth of the driven gear 217 is greater than the number of teeth of the driving gear 216, it can reduce speed and increase torque, allowing the telescopic rod 22 to obtain a greater pushing force to overcome the large frictional resistance deep in the pipeline.

[0041] In some embodiments, the end face of the nozzle 31 away from the telescopic rod 22 is a hemispherical surface, and a plurality of water outlet holes are provided on the hemispherical surface.

[0042] The nozzle of this invention adopts a hemispherical structure with multiple water outlet holes on the hemisphere. This allows the cleaning fluid to be sprayed from the nozzle end face at multiple angles and directions, forming a jet flushing surface covering the entire circumference of the pipe wall. Compared to a single-hole direct-jet nozzle, the hemispherical multi-hole arrangement can simultaneously flush all circumferential positions of the pipe's inner wall, eliminating flushing dead zones and improving the coverage and descaling efficiency of a single flush. The streamlined shape of the hemispherical surface also reduces the resistance when the nozzle advances within the pipe, facilitating its smooth passage through bends or changes in inner diameter.

[0043] Specifically, the hemispherical radius of the nozzle 31 matches the outer diameter of the telescopic rod 22. Multiple water outlets are equidistantly distributed along the hemispherical surface of the nozzle 31 in a concentric circle or spiral pattern. The diameter and number of water outlets can be designed according to the flow rate and pressure of the cleaning fluid. The diameter of a single water outlet can be selected in the range of 0.5 mm to 2 mm. The total flow area of ​​the water outlets should be smaller than the flow area of ​​the water guide pipe 353 to ensure that a high jet velocity and rinsing kinetic energy are maintained at the water outlets.

[0044] Furthermore, the nozzle 31 can be made of stainless steel or engineering plastic, and the connection between the nozzle 31 and the telescopic rod 22 can be a threaded connection or a quick-release buckle connection, which facilitates the quick replacement of the nozzle 31 after use and wear.

[0045] In some embodiments, the cleaning assembly 3 further includes a mounting block 32 and a spiral tab 33. The mounting block 32 is disposed between the nozzle 31 and the telescopic rod 22, and the spiral tab 33 is spirally wound on the mounting block 32. The spiral tab 33 is used to scrape off dirt from the inner wall of the pipeline when the nozzle 31 rotates.

[0046] The spiral protrusions of this invention are mounted on a mounting block between the nozzle and the telescopic rod, rotating together with the telescopic rod. They mechanically scrape away hard scale adhering to the pipe wall before the nozzle flushes. The spiral protrusions are arranged in a spiral winding pattern, forming a continuous scraping surface along the circumference of the pipe wall during rotation. This first loosens and peels away the hard scale layer tightly adhering to the pipe wall, and then the cleaning fluid sprayed from the nozzle washes away the loosened scale. This achieves a combined scraping-then-flushing cleaning mode, significantly improving the ability to remove stubborn hard scale.

[0047] Specifically, the mounting block 32 is cylindrical, with one end fixedly connected to the end of the telescopic rod 22 and the other end fixedly connected to the nozzle 31. The spiral protrusion 33 spirals upwards along the outer circumference of the mounting block 32, and the direction of rotation of the spiral protrusion 33 matches the rotation direction of the telescopic rod 22, so that the spiral protrusion 33, when rotating, generates a pushing effect towards the depth or outside of the pipeline, assisting in the discharge of dirt and debris. The outer diameter of the spiral protrusion 33 is slightly smaller than the inner diameter of the pipeline to be cleaned, and the gap between them is controlled within the range of 0.5mm to 2mm to avoid direct hard contact between the spiral protrusion 33 and the pipeline wall, which could cause scratches.

[0048] Furthermore, the spiral protrusion 33 can be made of wear-resistant polyurethane, nylon, or phosphor bronze, which provides sufficient scraping strength while avoiding damage to flexible materials such as copper pipes. The cross-sectional shape of the spiral protrusion 33 can be rectangular, trapezoidal, or triangular, and its thickness and height are determined according to the thickness and hardness of the scale layer.

[0049] In some embodiments, the cleaning assembly 3 further includes bristles 34 disposed on the outer wall of the telescopic rod 22, which are used to scrub the inner wall of the pipeline when the telescopic rod 22 moves.

[0050] The bristles in this embodiment of the invention are disposed on the outer wall of the telescopic rod and move linearly and rotary along with the telescopic rod, enabling gentle brushing of the pipe wall between the spiral convex scraping and the nozzle rinsing. The flexibility of the bristles can adapt to slight changes in the inner diameter of the pipe, cleaning loose scale and sludge remaining on the pipe wall, filling the cleaning gradient gap between hard scraping and liquid rinsing, forming a triple-layer cleaning mechanism of scraping, brushing, and rinsing, further improving the thoroughness of the cleaning effect.

[0051] Specifically, the bristles 34 are evenly arranged circumferentially along the outer wall of the telescopic rod 22, and can be arranged in a ring or spiral. The length of the bristles 34 is determined according to the inner diameter of the pipe to be cleaned. The diameter of the envelope circle formed by the ends of the bristles 34 should be slightly larger than the inner diameter of the pipe, so that the bristles 34 are in a slightly compressed state after entering the pipe, maintaining appropriate contact pressure with the pipe wall. The material of the bristles 34 can be nylon, polypropylene, or pig bristles, etc., and the hardness and density of the bristles 34 can be selected according to the type of scale.

[0052] Furthermore, the bristles 34 can be fixed to the outer wall of the telescopic rod 22 by means of implantation, pressure strip fixation, or spiral winding, or they can be fitted onto the telescopic rod 22 by a brush sleeve structure for easy replacement after wear. In the axial direction of the telescopic rod 22, the bristles 34 can be arranged in multiple groups in segments, and a mounting block 32 for a spiral protrusion 33 can be set between two adjacent groups of bristles 34 to form a cleaning layout of alternating scraping and brushing.

[0053] In some embodiments, the cleaning assembly 3 further includes a liquid supply component 35, which includes a pump 351, a water supply pipe 352, and a water guide pipe 353. The pump 351 is disposed in the housing 1. One end of the pump 351 is connected to the water supply pipe 352, and the other end of the pump 351 is connected to the nozzle 31 through the water guide pipe 353 for supplying cleaning fluid to the nozzle 31.

[0054] The liquid supply component of this invention uses a pump to draw cleaning fluid through a water supply pipe and then delivers it to the nozzle through a water guide pipe, providing a continuous, stable, and pressurized cleaning fluid source for the nozzle. The liquid supply component is integrated into the housing, giving the cleaning device independent liquid supply capabilities, eliminating the need for an external high-pressure water source, and improving the device's portability and field applicability. The start / stop and flow rate adjustment of the pump can be linked to the motion control of the moving components, achieving an automated liquid supply logic where rinsing begins when the nozzle is in position and stops when it is out of position.

[0055] Specifically, the extraction pump 351 can be a diaphragm pump, plunger pump, or centrifugal pump, and its flow rate and head are determined according to the working pressure and flow rate required by the nozzle 31. One end of the water supply pipe 352 is connected to the cleaning fluid storage tank or an external water source, and the other end is connected to the suction port of the extraction pump 351. The water guide pipe 353 is a telescopic water guide pipe or a flexible hose, one end of which is connected to the discharge port of the extraction pump 351, and the other end passes through the inner hole of the telescopic rod 22 or is laid along the outer wall of the telescopic rod 22, and finally connects to the inlet of the nozzle 31.

[0056] Furthermore, a guide bracket or sleeve can be installed in the path of the water guide pipe 353 inside the telescopic rod 22 to prevent the water guide pipe 353 from twisting or being squeezed when it moves with the telescopic rod 22. The liquid supply component 35 may also include a filter, which is installed at the water inlet end of the water supply pipe 352 or before the suction port of the extraction pump 351 to intercept large particulate impurities in the cleaning fluid and prevent the water outlet of the nozzle 31 from becoming clogged.

[0057] In some embodiments, the housing 1 includes a heat dissipation hole 11, which is formed on the housing 1. One end of the heat dissipation hole 11 communicates with the interior of the housing 1, and the other end of the heat dissipation hole 11 communicates with the outside.

[0058] The heat dissipation holes in this embodiment of the invention are located on the housing, connecting the interior of the housing to the outside atmosphere. This allows for the timely removal of heat generated by components such as the motor and pump during operation, preventing excessively high temperatures inside the housing from affecting the stability and lifespan of electrical components. The arrangement of the heat dissipation holes utilizes both natural convection and airflow circulation created by the pressure difference between the inside and outside of the housing, accelerating heat dissipation.

[0059] Specifically, the heat dissipation holes 11 can be located on the side or upper rear end face of the housing 1, avoiding the area where the operator can hold the device. The shape of the heat dissipation holes 11 can be circular, oblong, or grid-shaped, and a dustproof mesh or waterproof and breathable membrane can be installed at the opening to balance heat dissipation and protection. The heat dissipation holes 11 can be arranged in groups, with each group containing multiple heat dissipation holes, spaced apart along the circumference or axial direction of the housing 1.

[0060] Furthermore, a flow guide fan can be installed inside the housing 1. The flow guide fan is fixed on the inner wall of the housing 1 or on the end cover. When started, it forms a forced airflow circulation to enhance the heat dissipation effect.

[0061] In some embodiments, the pipeline cleaning device further includes a control panel 4, which is disposed on the housing 1. The moving part 21 and the extraction pump 351 are connected to the control panel 4, and the control panel 4 is used to control the operation of the moving part 21 and the extraction pump 351.

[0062] The control panel of this invention, mounted on the housing and connected to the moving parts and the extraction pump, provides operators with a centralized human-machine interface for control. Through the control panel, operators can easily start and stop the motor, adjust the extension speed and depth of the telescopic rod, and control the flow rate and start / stop of the extraction pump, achieving electrified and automated control of the cleaning operation. Operators no longer need to repeatedly manually adjust various components during the cleaning process, reducing operational complexity and improving operational consistency and the controllability of cleaning quality.

[0063] Specifically, the control panel 4 can be located on the top of the housing 1 or in a position easily accessible to the operator's fingers. The control panel 4 may include functional components such as a power switch, speed control knob, extension / retraction control button, and liquid supply start / stop button. The control panel 4 also includes a display screen for displaying operating parameter information such as the current extension depth of the telescopic rod 22, the speed of the motor 215, and the working status of the extraction pump 351.

[0064] Furthermore, the control panel 4 can form a closed-loop control system with sensors such as the encoder and limit switch of the motor 215. After the operator sets the target cleaning depth through the control panel 4, the control system automatically drives the motor 215 to rotate. When the telescopic rod 22 reaches the set depth, the motor 215 automatically stops. After the nozzle 31 stays at the position for a predetermined time to complete the rinsing, the motor 215 reverses to drive the telescopic rod 22 to retract and reset, realizing one-button automatic deep cleaning.

[0065] Furthermore, the pipeline cleaning device also includes a handle 5, which is mounted on the housing 1, and the handle 5 and the housing 1 form a gun-shaped structure.

[0066] In this embodiment of the invention, the handle and housing form a gun-shaped structure, conforming to an ergonomic grip posture, facilitating one-handed operation and aiming. The tilt angle of the gun-shaped structure ensures that the direction of force applied by the hand is roughly consistent with the forward and backward movement of the telescopic rod, making pushing operations more natural and effortless, and reducing hand fatigue during prolonged work. The handle 5 can also be equipped with anti-slip textures or covered with a flexible protective sleeve to increase friction between the hand and the handle and improve grip comfort.

[0067] Specifically, the handle 5 and the housing 1 can be assembled by integral molding, screw fixing, or snap-fit ​​connection. The handle 5 can be located below or behind the housing 1, forming a certain angle with the axis of the housing 1, with the angle ranging from 60 degrees to 120 degrees. The handle 5 has a hollow structure, and the water supply pipe 352 can pass through the interior of the handle 5 or be laid along the outer wall of the handle 5, making the water supply pipeline layout more compact.
