Abstract
Description
Technical Field
[0001] This invention belongs to the field of pipeline maintenance technology, and in particular relates to a heating pipeline maintenance and cleaning device. Background Technology
[0002] In heating systems, pipe connections (such as welded, heat-fused, and threaded joints) are prone to forming gaps due to process characteristics, becoming the core area for impurity accumulation. Mud, rust, scale, and biological slime in the heating circulating water will embed themselves into the gaps as the water flow changes and gradually harden. This not only reduces the inner diameter of the pipe and lowers the heating efficiency, but also aggravates gap corrosion, increases the risk of pipe leakage, and seriously affects the stable operation of the system.
[0003] Current maintenance methods mostly rely on conventional means such as cleaning brushes, mechanical scrapers, or low-pressure flushing. However, brushes cannot penetrate deep into crevices to remove stubborn impurities, leaving blind spots in cleaning. Scrapers are difficult to adapt to the structure of crevices and may scratch the inner wall of the pipe. In addition, some pipes are installed in narrow spaces, which limits the operation of conventional methods. Impurities at the connection points can never be completely cleaned, resulting in shortened maintenance cycles and increased costs.
[0004] Therefore, a heating pipe maintenance and cleaning device is proposed. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned problems by providing a heating pipe maintenance and cleaning device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heating pipe maintenance and cleaning device, comprising a housing and multiple sets of electric rollers disposed on the outer wall of the housing, and further comprising: A fixing plate is fixedly disposed inside the housing, and a cleaning mechanism is provided on the surface of the fixing plate and at the end of the housing; A scraping mechanism is disposed on one side of the cleaning mechanism, and the scraping mechanism is integrated with the cleaning mechanism; A crevice cleaning mechanism is disposed on one side of the scraping mechanism, and the scraping mechanism and the crevice cleaning mechanism are integrated into one unit; A gap detection mechanism is disposed on one side of the gap cleaning mechanism, and the gap detection mechanism and the gap cleaning mechanism are integrated into one unit; A PLC controller is fixedly mounted on the surface of the fixed plate. A storage battery is fixedly mounted on the surface of the fixed plate. The storage battery, electric roller, cleaning mechanism, crevice cleaning mechanism, and crevice detection mechanism are all electrically connected to the PLC controller.
[0007] Preferably, the cleaning mechanism includes a motor fixedly mounted on the surface of the fixed plate, a rotating tube fixedly mounted at the output end of the motor, a fixed tube fixedly connected at the end of the rotating tube away from the motor, a hollow annular plate rotatably mounted at the end of the housing, both ends of the fixed tube being fixedly connected to the inner sidewall of the hollow annular plate, an annular cleaning plate mounted on the outside of the hollow annular plate, a plurality of evenly distributed connecting blocks fixedly mounted between the inner wall of the annular cleaning plate and the outer wall of the hollow annular plate, and an annular cleaning brush fixedly mounted on the outer sidewall of the annular cleaning plate.
[0008] Preferably, a vacuum cleaner is fixedly mounted on the surface of the fixed plate, a suction pipe is fixedly mounted on the suction end of the vacuum cleaner, a hollow disk is rotatably mounted on the wall of the rotating pipe, connecting rods fixedly connected to the surface of the fixed plate are fixedly mounted on both sides of the hollow disk, an air suction hole is opened on the part of the rotating pipe wall located inside the hollow disk, the end of the suction pipe away from the vacuum cleaner is fixedly connected to the side wall of the hollow disk, and a plurality of evenly distributed suction pipes are fixedly mounted on the outer side wall of the hollow annular plate.
[0009] Preferably, the scraping mechanism includes a plurality of fixed rods fixedly disposed on the side wall of the annular cleaning plate, and the ends of the plurality of fixed rods away from the annular cleaning plate are fixedly provided with the same annular scraping plate, and the outer side wall of the annular scraping plate is fixedly provided with a plurality of evenly distributed triangular scraping heads.
[0010] Preferably, the crevice cleaning mechanism includes a mounting base located inside the annular scraper plate. Support rods are fixedly provided between the upper and lower sides of the mounting base and the inner wall of the annular scraper plate. Wireless electric push rods are fixedly provided on both the upper and lower sides of the mounting base. Wireless pressure sensors are fixedly provided at the moving ends of the two wireless electric push rods, and fixed blocks are fixedly provided at the detection ends of the pressure sensors. Triangular crevice cleaning heads are fixedly provided on the side of the two fixed blocks away from the pressure sensors.
[0011] Preferably, the gap detection mechanism includes an L-shaped extension rod fixedly mounted on the side wall of the mounting base. The end of the L-shaped extension rod has a slot, and a movable rod is provided inside the slot. A fixing ring is fixedly provided inside the slot. A spring is fixedly provided between one end of the movable rod and the fixing ring. A pull rope passing through the inside of the fixing ring is fixedly provided at one end of the movable rod. A wireless tension sensor is fixedly provided at the bottom of the slot. The end of the pull rope away from the movable rod is fixedly connected to the detection end of the pressure sensor.
[0012] Preferably, a tapered head is fixedly provided at one end of the movable rod outside the L-shaped extension rod, and limiting blocks are fixedly provided on both sides of the movable rod, and limiting grooves that cooperate with the limiting blocks are provided on both sides of the slot.
[0013] Preferably, there are four groups of electric rollers, and each group has two electric rollers.
[0014] Compared with existing technologies, the advantages of this invention are as follows: 1. With the included gap detection and gap cleaning mechanisms, the conical head of the gap detection mechanism automatically extends into the pipe connection gap under the action of spring force as the housing moves. The moving rod pulls the rope to trigger the wireless tension sensor, which feeds back the gap position signal to the PLC controller in real time. The PLC controller controls the electric roller to precisely adjust the housing's travel distance based on the signal. After the gap cleaning mechanism moves to the gap position, the wireless electric push rod pushes the triangular gap cleaning head into the gap. Its tip structure can adapt to the gap shape, effectively scraping away stubborn mud, rust, and scale. At the same time, the wireless pressure sensor monitors the cleaning pressure in real time to prevent excessive force from scratching the inner wall of the pipe. This solves the problem that conventional methods are difficult to clean deep into gaps and are prone to damaging the pipe, significantly reducing the risk of leakage caused by gap corrosion.
[0015] 2. With the provided scraping mechanism, as it moves synchronously with the housing, multiple triangular scraping heads on the outer side of the annular scraping plate can closely adhere to the inner wall of the pipe, specifically scraping away hard scale and rust deposits adhering to the periphery of the gaps and the inner wall of the pipe. This compensates for the shortcomings of gap cleaning mechanisms that only target the inside of the gaps and are insufficient in treating residual impurities in the surrounding area. The sharp structure of the triangular scraping heads can easily break down stubborn impurities, and the annular distribution design can achieve full circumferential coverage of the inner wall of the pipe, avoiding local impurity residue. This lays the foundation for the subsequent fine cleaning by the sweeping mechanism, further improving the cleanliness of the inner wall of the pipe and reducing the impact of impurities on the efficiency of heating water circulation.
[0016] 3. Through the established cleaning mechanism, the motor drives the rotating tube to rotate, which in turn drives the hollow annular plate and the annular cleaning plate to rotate through the fixed tube. This allows the annular cleaning brush to perform a 360° rotating sweep on the inner wall and crevices of the pipe, effectively removing fine impurities and dust remaining in the scraping mechanism and preventing secondary adhesion of impurities. At the same time, the vacuum cleaner forms a negative pressure suction channel through the suction pipe, the hollow disc, and the suction pipe on the outside of the hollow annular plate, which sucks in and collects the impurities generated during cleaning in real time. This not only prevents impurities from accumulating again with the heating water circulation, but also avoids the problem of impurities scattering and contaminating the pipes or operating environment during conventional cleaning.

[0024] The PLC controller 8 is fixedly mounted on the surface of the fixed plate 3. The fixed plate 3 is also fixedly mounted with a battery 9. The battery 9, the electric roller 2, the cleaning mechanism 4, the crevice cleaning mechanism 6, and the crevice detection mechanism 7 are all electrically connected to the PLC controller 8.
[0025] The operating principle of the present invention is described as follows: When in use, the housing 1 is first placed inside the heating pipe. The PLC controller 8 starts four sets of electric rollers 2. The electric rollers 2 drive the housing 1 to move at a constant speed inside the pipe, so that the gap detection mechanism 7, gap cleaning mechanism 6, scraping mechanism 5 and sweeping mechanism 4 arranged sequentially at the end of the housing 1 along the walking direction gradually pass through the inner wall of the pipe and carry out cleaning operations. When the gap detection mechanism 7 moves with the housing 1, the tapered head 78 at the end of its L-shaped extension rod 71 contacts and slides against the inner wall of the pipe. If the tapered head 78 passes through the pipe connection gap, the tapered head 78 extends into the gap under the elastic force of the spring 75, driving the moving rod 73 to move along the slot 72 (the limiting block 79 slides along the limiting groove to prevent the moving rod 73 from deviating). The moving rod 73 pulls the pull rope 76, causing the pull rope 76 to generate tension on the wireless tension sensor 77. The wireless tension sensor 77 feeds back the signal to the PLC controller 8, determining that this is a pipe connection gap. After receiving the signal, the PLC controller 8 controls the electric roller 2 to continue driving the housing 1 at a constant speed (for example, for 3 seconds). When the gap cleaning mechanism 6 moves to the gap position, the PLC controller 8 instructs the wireless electric push rod 63 on the mounting base 61 to extend and push the wireless pressure sensor 64, the fixing block 65 and the triangular gap cleaning head 66 to move, so that the tip of the triangular gap cleaning head 66 can accurately extend into the gap and scrape away stubborn impurities in the gap as the housing 1 moves. The wireless pressure sensor 64 monitors the cleaning pressure in real time to avoid excessive force from scratching the inner wall of the pipe. Subsequently, the scraping mechanism 5 arrives at the position along with the housing 1, and the triangular scraping head 53 on the outer side of its annular scraping plate 52 (connected to the annular cleaning plate 45 via the fixing rod 51) further scrapes away the harder impurities remaining on the inner wall of the pipe and around the gaps. Finally, the cleaning mechanism 4 is activated, and the motor 41 drives the rotating pipe 42 to rotate. The rotating pipe 42 drives the hollow annular plate 44, the annular cleaning plate 45, and the annular cleaning brush 47 to rotate through the fixed pipe 43. The annular cleaning brush 47 thoroughly cleans the inner wall and gaps of the pipe. At the same time, the vacuum cleaner 48 is activated. The vacuum cleaner 48 sucks up and collects the impurities generated during cleaning in real time through the suction pipe 49, the hollow disc 410 (the suction hole 412 on the pipe wall of the rotating pipe 42 is connected to the hollow disc 410), and the suction pipe 413 on the outside of the hollow annular plate 44. The entire process is powered by the battery 9. The PLC controller 8 coordinates and controls the various mechanisms to work together, achieving efficient and thorough cleaning of the inner wall and connecting gaps of the pipe.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
