Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler pipe unblocking technology, specifically a novel boiler pipe unblocking device. Background Technology
[0002] Boiler piping is a crucial component of the boiler system, playing a vital role in transporting the medium and significantly impacting the safe and economical operation of the boiler. Boiler piping is classified by purpose as follows: Feedwater piping: used to supply water to the boiler, typically extending from the feedwater pump outlet to the boiler. Main steam piping: used to transport steam generated by the boiler to the steam distribution cylinder or steam usage point. Reheat steam piping: in power plant boilers, used to return steam after it has been used by the turbine to the boiler for reheating. Other piping: such as circulating pump inlet and outlet piping, etc. During operation, boiler piping can become clogged due to the accumulation of ash, impurities, unburned particles, and slag from the fuel, necessitating the use of unclogging devices.
[0003] Traditional boiler pipe unblocking devices use high-pressure nozzles to spray high-pressure water onto the inner walls of the pipes. However, when large impurities adhere to the pipe walls, flushing alone is insufficient to remove them, reducing the unblocking effect. To address this issue, some boiler pipe unblocking devices incorporate a rotating shaft with a scraper on its surface. This shaft is coaxially connected to a motor. When the shaft is inserted into the boiler pipe, the motor drives the shaft and scraper to rotate, scraping away impurities and ensuring effective unblocking. However, this method suffers from limitations because the scraper's overall size is fixed, and boiler pipes vary in size, reducing the device's applicability and limiting its cleaning effectiveness. Therefore, a novel boiler pipe unblocking device is proposed. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a novel boiler pipe unblocking device to solve the aforementioned technical problems that not only reduce the applicability of the device but also limit the cleaning effect.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel boiler pipe unblocking device, comprising:
[0008] The guide cylinder and the fixed column disposed in the inner cavity of the guide cylinder, wherein the surface of the fixed column is uniformly mounted with annular plates, and a rotating gear is rotatably connected above the guide cylinder, wherein the rotating gear meshes with the annular plates, and a first drive motor is coaxially connected to the end of the rotating gear.
[0009] A fixed base is provided at the end of a fixed column, and a second drive motor and a fixed block are respectively installed at both ends of the fixed base. A cam is rotatably connected to the end of the fixed base, and the cam is coaxially connected to the second drive motor. Arc-shaped scrapers are provided above and below the fixed block.
[0010] A fixed rod is mounted on the upper and lower surfaces of the fixed block, and a sliding plate is fitted on each surface of the fixed rod. A side connecting column connects the sliding plate and the arc-shaped scraper, and a return spring is fitted on each surface of the fixed rod. By aligning the guide cylinder with the end of the boiler pipe, the first drive motor, powered by an external power source, drives a rotating gear on the guide cylinder to rotate and adjusts the rotation direction of the rotating gear. The annular plate, according to the rotation direction of the rotating gear, drives the fixed column to move along the guide cylinder and enter the inner cavity of the boiler pipe. The rotation of the rotating gear, through the annular plate, drives the guide cylinder to move in a manner similar to the gear driving the toothed plate. After the fixed seat enters the inner cavity of the boiler pipe, the second drive motor, powered by an external power source, drives a cam on the fixed seat to rotate on the fixed block and adjusts the cam's rotation direction. The cam's convex end drives the arc-shaped scraper to move on the fixed block. As the arc-shaped scraper moves, it drives the sliding plate along the fixed rod through the side connecting column, compressing the return spring and causing the arc-shaped scraper to contact the boiler pipe. After the scraper is tightly fitted to the inner wall of the pipe, it moves with the fixed column to scrape away impurities from the inner wall of the boiler pipe, thus preventing blockage caused by excessive impurities. On the one hand, the height of the arc-shaped scraper can be adjusted within a certain range according to the size of different boiler pipes, ensuring a tight fit between the arc-shaped scraper and the inner wall of the boiler pipe. This not only increases the applicability of the device but also guarantees the cleaning effect. On the other hand, the fixed column can be rotated on the guide cylinder, and the rotation of the fixed column will not affect the meshing of the annular plate and the rotating gear. This allows the fixed column to drive the arc-shaped scraper to move and rotate within the inner cavity of the boiler pipe, thereby enabling a comprehensive cleaning of impurities from the inner wall of the boiler pipe.
[0011] Preferably, the end of the fixing post is threaded with an anti-slip handle, and the fixing post is composed of short columns. After the fixing post is fixed, the anti-slip handle can be installed on the fixing post, so that the anti-slip handle drives the fixing post to rotate inside the guide cylinder, and facilitates disassembly and assembly operations.
[0012] Preferably, there are two sets of short columns, each with a threaded connecting hole at its outer end and a threaded connecting block installed at its inner end. The length of the fixing column can be adjusted by increasing or decreasing the number of short columns according to the length of the boiler pipe, thus enabling unblocking operations on longer boiler pipes.
[0013] Preferably, the inner wall of the threaded connecting hole is provided with an internal thread, and the surface of the threaded connecting block is provided with an external thread, and the threaded connecting hole and the threaded connecting block are threadedly connected. When adjacent short cylinders are connected, the threaded connecting block can be rotated into the inner cavity of the threaded connecting hole.
[0014] Preferably, a fixing rod is installed between the fixing base and the fixing column, and the second drive motor is located between the fixing base and the fixing column. The fixing base drives the fixing column to move via the fixing rod, while the second drive motor drives the connecting structure to rotate on the fixing base.
[0015] Preferably, the ends of the return spring are tightly fitted to the fixed rod and the sliding plate, respectively. When the sliding plate moves along the fixed rod, it compresses the return spring, and the return spring can drive the sliding plate to perform a reset operation on the fixed rod.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a novel boiler pipe unblocking device, which has the following beneficial effects:
[0018] This novel boiler pipe unblocking device works by aligning a guide cylinder with the end of the boiler pipe. A first drive motor, powered by an external power source, rotates a gear on the guide cylinder. The rotation direction of the gear is adjusted, and a ring plate, according to the gear's rotation, moves a fixed column along the guide cylinder into the boiler pipe cavity. Once the fixed column is inside the boiler pipe cavity, a second drive motor, powered on, rotates a cam on the fixed block. The cam's rotation direction is adjusted, and the cam's convex end moves an arc-shaped scraper on the fixed block. As the scraper moves, it drives a sliding plate along a fixed rod via a side connecting column, compressing a return spring and ensuring the arc-shaped scraper is in close contact with the inner wall of the boiler pipe. After assembly, the scraper moves with the fixed column to scrape away impurities from the inner wall of the boiler pipes, thus preventing blockages caused by excessive impurities. The height of the arc-shaped scraper can be adjusted within a certain range according to the size of different boiler pipes, ensuring a tight fit between the arc-shaped scraper and the inner wall of the boiler pipes. This not only increases the applicability of the device but also guarantees the cleaning effect. At the same time, the fixed column can be rotated on the guide cylinder, and the rotation of the fixed column will not affect the meshing of the annular plate and the rotating gear. This allows the fixed column to drive the arc-shaped scraper to move and rotate within the boiler pipe cavity, thereby enabling a comprehensive cleaning of impurities from the inner wall of the boiler pipes.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution: a novel boiler pipe unblocking device, comprising: (see details) Figure 1 , Figure 2 , Figure 4 , Figure 5 The guide cylinder 1 and the fixed column 2 disposed in the inner cavity of the guide cylinder 1, and the surface of the fixed column 2 is uniformly equipped with an annular plate 3, and a rotating gear 4 is rotatably connected above the guide cylinder 1, and the rotating gear 4 meshes with the annular plate 3, and a first drive motor 5 is coaxially connected to the end of the rotating gear 4.
[0027] A fixed base 10 is provided at the end of the fixed column 2, and a second drive motor 11 and a fixed block 12 are respectively installed at both ends of the fixed base 10. A cam 13 is rotatably connected to the end of the fixed base 10, and the cam 13 is coaxially connected to the second drive motor 11. An arc-shaped scraper 14 is provided above and below the fixed block 12.
[0028] A fixed rod 15 is provided on the upper and lower surfaces of the fixed block 12, and a sliding plate 16 is sleeved on the surface of the fixed rod 15. A side connecting column 17 is connected between the sliding plate 16 and the arc-shaped scraper 14, and a return spring 18 is sleeved on the surface of the fixed rod 15. By aligning the guide cylinder 1 with the end of the boiler pipe, the first drive motor 5, powered by an external power source, drives the rotating gear 4 to rotate on the guide cylinder 1 and adjusts the direction of rotation of the rotating gear 4. The annular plate 3, according to the direction of rotation of the rotating gear 4, drives the fixed column 2 to move along the guide cylinder 1 and enter the inner cavity of the boiler pipe. The rotation of the rotating gear 4, through the annular plate 3, drives the guide cylinder 1 to move in a manner similar to that of a gear driving a toothed block. When the fixed seat 10 enters the inner cavity of the boiler pipe, the second drive motor 11, powered by an external power source, drives the cam 13 to rotate on the fixed block 12 on the fixed seat 10 and adjusts the direction of rotation of the cam 13. The convex end of the cam 13 drives the arc-shaped scraper 14 to move on the fixed block 12. When the arc-shaped scraper 14 moves, it drives the sliding plate 16 to move along the fixed rod 15 through the side connecting column 17, and also affects the return spring 18. The scraping action, which causes the arc-shaped scraper 14 to fit tightly against the inner wall of the boiler pipe, moves with the fixed column 2 to scrape away impurities from the inner wall of the boiler pipe. This prevents blockage caused by excessive impurities on the inner wall of the boiler pipe. On the one hand, the height of the arc-shaped scraper 14 can be adjusted within a certain range according to the size of different boiler pipes, ensuring a tight fit between the arc-shaped scraper 14 and the inner wall of the boiler pipe. This not only increases the applicability of the device but also ensures the cleaning effect. On the other hand, the fixed column 2 can be rotated on the guide cylinder 1, and the rotation of the fixed column 2 will not affect the meshing of the annular plate 3 and the rotating gear 4. This allows the fixed column 2 to drive the arc-shaped scraper 14 to move and rotate within the inner cavity of the boiler pipe, thus enabling a comprehensive cleaning of impurities on the inner wall of the boiler pipe.
[0029] Please see Figure 3 The fixed column 2 has a threaded connection to an anti-slip handle 6 at its end, and the fixed column 2 is composed of short columns 7. After the fixed column 2 is fixed, the anti-slip handle 6 can be installed on the fixed column 2, allowing the anti-slip handle 6 to drive the fixed column 2 to rotate within the guide cylinder 1, facilitating disassembly and assembly. There are two sets of short columns 7, and each short column 7 has a threaded connecting hole 9 at its outer end and a threaded connecting block 8 installed at its inner end. The length of the fixed column 2 can be adjusted by increasing or decreasing the number of short columns 7 according to the length of the boiler pipe, thus enabling unblocking operations on longer boiler pipes. The inner wall of the threaded connecting hole 9 has an internal thread, and the surface of the threaded connecting block 8 has an external thread, with the threaded connecting hole 9 and the threaded connecting block 8 being threadedly connected. When adjacent short columns 7 are connected, the threaded connecting block 8 can be rotated into the inner cavity of the threaded connecting hole 9.
[0030] Please see Figure 4 , Figure 5A fixing rod is installed between the fixing base 10 and the fixing column 2, and the second drive motor 11 is located between the fixing base 10 and the fixing column 2. The fixing base 10 drives the fixing column 2 to move via the fixing rod, while the second drive motor 11 drives the connecting structure to rotate on the fixing base 10. The ends of the return spring 18 are tightly fitted with the fixing rod body 15 and the sliding plate 16, respectively. When the sliding plate 16 moves along the fixing rod body 15, it presses the return spring 18, and the return spring 18 can drive the sliding plate 16 to perform a reset operation on the fixing rod body 15.
[0031] This solution: By aligning the guide cylinder 1 with the end of the boiler pipe, the first drive motor 5, powered by an external power source, drives the rotating gear 4 to rotate on the guide cylinder 1. The direction of rotation of the rotating gear 4 is adjusted, and the annular plate 3, according to the direction of rotation of the rotating gear 4, drives the fixed column 2 to move along the guide cylinder 1 into the inner cavity of the boiler pipe. After fixing the fixed column 2, the anti-slip handle 6 is installed on the fixed column 2, causing the anti-slip handle 6 to drive the fixed column 2 to rotate inside the guide cylinder 1. The rotating gear 4, through the annular plate 3, drives the guide cylinder 1 to move in a manner similar to a gear driving a toothed block plate. When the fixed seat 10 enters the inner cavity of the boiler pipe, the second drive motor 11, powered by an external power source, drives the cam 13 to rotate on the fixed block 12 on the fixed seat 10, and the direction of rotation of the cam 13 is adjusted. The convex end of the cam 13 drives the arc-shaped scraper 14 to move on the fixed block 12. When the arc-shaped scraper 14 moves, it drives the sliding plate 16 to move along the fixed rod 15 through the side connecting column 17 and squeezes the return spring 18. The return spring 18 can drive the sliding plate 16 to perform a reset operation on the fixed rod 15, so that the arc-shaped scraper 14 is tightly attached to the inner wall of the boiler pipe and moves with the fixed column 2 to scrape off the impurities on the inner wall of the boiler pipe, thereby avoiding the blockage caused by excessive impurities on the inner wall of the boiler pipe. When adjacent short columns 7 are connected, the threaded connecting block 8 can be rotated into the inner cavity of the threaded connecting hole 9. The length of the fixed column 2 can be adjusted within a certain range according to the length of the boiler pipe by increasing or decreasing the number of short columns 7.
