Description

Technical Field

[0001] This utility model relates to the field of heating pipe technology, specifically a cleaning device for the inner wall of heating pipes. Background Technology

[0002] A cleaning device for the inner walls of heating pipes is a specialized piece of equipment designed primarily to remove scale, rust, and biological slime deposits in hot water or steam heating systems. It typically achieves efficient cleaning through high-pressure water jet technology or mechanical scraping, significantly restoring the pipe's flow cross-section, improving heating efficiency, saving energy, and effectively extending the service life of the pipe network. It is a key maintenance tool for ensuring the stable and economical operation of heating systems.

[0003] According to a public disclosure (CN221248264U), a cleaning device for the inner wall of heating pipes is disclosed. This device relates to the field of heating pipe technology and includes a mounting frame. A sleeve is fixedly mounted on one side of the mounting frame, and a drive shaft is rotatably mounted inside the sleeve. A motor is fixedly mounted on the mounting frame. An installation tube is mounted on the other end of the sleeve. A grinding head is rotatably mounted on one end of the installation tube, and a grinding cylinder is rotatably mounted on the outside of the installation tube. A pair of fixed rods are symmetrically arranged on the outside of the installation tube, and idler wheels are rotatably mounted on each of the fixed rods. Gear rings that mesh with the idler wheels are fixedly mounted on both the grinding head and the grinding cylinder. This invention cleans the inner wall of the heating pipe using the grinding head and the grinding brush on the grinding cylinder. The idler wheels allow the grinding cylinder and the grinding head to rotate in opposite directions, thus offsetting most of the circumferential force generated by the grinding head on the sleeve, preventing the sleeve from rotating inside the heating pipe, and reducing the labor intensity of operators manually supporting the sleeve.

[0004] In the aforementioned device, the grinding head and the grinding brush on the grinding cylinder can reduce the labor intensity of operators when manually supporting the sleeve, but it is difficult to clean pipes of different diameters in a convenient way, resulting in poor device adaptability, inability to fit the inner wall of pipes of different diameters, incomplete cleaning, and increased subsequent maintenance costs.

[0005] In view of this, we propose a cleaning device for the inner wall of heating pipes. Summary of the Invention

[0006] The purpose of this utility model is to provide a cleaning device for the inner wall of heating pipes, which solves the problem of cleaning pipes of different diameters.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A cleaning device for the inner wall of heating pipes includes a cleaning unit, which includes a mounting frame. A support plate is fixedly connected to the top of the mounting frame. A motor is fixedly connected to the top of the support plate. A connecting column is fixedly connected to the output shaft of the motor. A cylindrical plate is fixedly connected to the end of the connecting column away from the motor. A connecting rod is fixedly connected to the middle of the cylindrical plate on the side away from the connecting column. A sleeve is fixedly connected to the circumferential surface of the connecting rod on the end away from the cylindrical plate. A baffle is fixedly connected to one end of the sleeve. A cleaning brush is provided on the outside of the sleeve. The device also includes an adjustment device for adjusting the cleaning range of the cleaning brush and a positioning device for fixing a rotating plate.

[0008] Preferably, the adjusting device includes a rotating plate, a connecting plate fixedly connected to the inner circumferential surface of the rotating plate, a turntable fixedly connected to the end of the connecting plate away from the inner circumferential surface of the rotating plate, a rotating rod slidably connected to the surface of the turntable, a long rod fixedly connected to the end of the rotating rod away from the turntable, a limit plate penetrating the surface of the long rod and slidably connected to the long rod, an adjusting plate fixedly connected to the end of the long rod away from the rotating rod, and a slider fixedly connected to one end of the adjusting plate.

[0009] Preferably, the rotating plate is disposed between the cylindrical plate and the sleeve, and is sleeved with both the cylindrical plate and the sleeve. The surface of the turntable is provided with an arc-shaped guide groove, and the end of the rotating rod away from the long rod is slidably connected to the arc-shaped guide groove on the surface of the turntable. One end of the limiting plate is fixedly connected to the inner circumferential surface of the sleeve. A cleaning brush is provided on the side of the adjusting plate away from the long rod, and there are five adjusting plates, which are evenly distributed on the circumferential surface of the sleeve. The end of the slider away from the adjusting plate is slidably connected to the sliding groove on the side of the baffle. A concave hole is provided on the circumferential surface of the rotating plate near the cylindrical plate.

[0010] Preferably, the positioning device includes a handle, a slide plate is fixedly connected to the bottom of the handle, a spring is fixedly connected to one end of the slide plate, a fixing plate is fixedly connected to the end of the spring away from the slide plate, and a locking pin is fixedly connected to the end of the slide plate away from the spring.

[0011] Preferably, the bottom of the fixing plate is fixedly connected to the circumferential surface of the cylindrical plate, and the surface of the fixing plate is provided with a sliding groove, and the surface of the sliding plate is slidably connected to the sliding groove provided on the surface of the fixing plate.

[0012] Preferably, the end of the locking pin away from the sliding plate is provided in a recessed hole on the circumferential surface of the rotating plate near the cylindrical plate.

[0013] Preferably, the surface of the baffle near the sleeve is provided with a groove, and the bottom end of the cleaning brush is disposed on the top surface of the adjusting plate.

[0014] By employing the above technical solution, this utility model provides a cleaning device for the inner wall of heating pipes. It has at least the following beneficial effects: 1. This utility model solves the problem of poor device adaptability, inability to fit the inner wall of pipes of different diameters, and increased subsequent maintenance costs when the cleaning range of the cleaning brush needs to be adjusted to adapt to different pipe diameters. When it is necessary to adjust the cleaning range of the cleaning brush to adapt to different pipe diameters, the rotating plate is first manually rotated so that the rotating plate is set between the cylindrical plate and the sleeve and rotates through the sleeve. The rotation is then transmitted to the turntable through the connecting plate fixedly connected to its inner circumference, thereby ensuring the stability of the adjustment plate movement.

[0015] 2. In the initial state, the spring is in its natural state, and its elastic thrust continues to act on the slide plate, thereby pushing the slide plate to slide along the groove opened on the fixed plate fixedly connected to the circumferential surface of the cylindrical plate. Then, the slide plate and the locking pin are automatically pushed back to reset, so that the locking pin is locked into the concave hole corresponding to the new position on the circumferential surface of the rotating plate, thereby completing the locking. This effectively prevents the cleaning diameter of the cleaning brush from changing unexpectedly due to vibration or resistance during the operation of the cleaning device.

[0018] 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.

[0019] A cleaning device for the inner wall of heating pipes, such as Figure 1 - Figure 5 As shown, the device includes a cleaning device 1, which includes a mounting frame 101. A support plate 102 is fixedly connected to the top of the mounting frame 101. A motor 103 is fixedly connected to the top of the support plate 102. A connecting column 104 is fixedly connected to the output shaft of the motor 103. A cylindrical plate 105 is fixedly connected to the end of the connecting column 104 away from the motor 103. A connecting rod 106 is fixedly connected to the middle of the side of the cylindrical plate 105 away from the connecting column 104. A sleeve 107 is fixedly connected to the circumferential surface of the connecting rod 106 away from the cylindrical plate 105. A baffle 108 is fixedly connected to one end of the sleeve 107. A cleaning brush 109 is provided on the outside of the sleeve 107. The device also includes an adjustment device 2 for adjusting the cleaning range of the cleaning brush 109 and a positioning device 3 for fixing the rotating plate 201.

[0020] The adjusting device 2 includes a rotating plate 201, a connecting plate 202 fixedly connected to the inner circumferential surface of the rotating plate 201, a turntable 203 fixedly connected to the end of the connecting plate 202 away from the inner circumferential surface of the rotating plate 201, a rotating rod 204 slidably connected to the surface of the turntable 203, a long rod 205 fixedly connected to the end of the rotating rod 204 away from the turntable 203, a limit plate 206 penetrating the surface of the long rod 205 and slidably connected to the long rod 205, an adjusting plate 207 fixedly connected to the end of the long rod 205 away from the rotating rod 204, and a slider 208 fixedly connected to the end of the adjusting plate 207. In the above design, the rotational motion of the rotating plate 201 is precisely transmitted to the turntable 203, thereby driving the subsequent adjusting device 2.

[0021] The rotating plate 201 is positioned between the cylindrical plate 105 and the sleeve 107, and is sleeved with both the cylindrical plate 105 and the sleeve 107. The surface of the turntable 203 is provided with an arc-shaped guide groove, and the end of the rotating rod 204 away from the long rod 205 is slidably connected to the arc-shaped guide groove on the surface of the turntable 203. One end of the limiting plate 206 is fixedly connected to the inner circumferential surface of the sleeve 107. A cleaning brush 109 is provided on the side of the adjusting plate 207 away from the long rod 205, and there are five adjusting plates 207, which are evenly distributed on the circumferential surface of the sleeve 107. The end of the slider 208 away from the adjusting plate 207 is slidably connected to the sliding groove on the side of the baffle 108. A concave hole is provided on the circumferential surface of the rotating plate 201 near the cylindrical plate 105. The above design converts the rotational motion of the turntable 203 into the radial linear motion of the rotating rod 204.

[0022] The positioning device 3 includes a handle 301, a slide plate 302 fixedly connected to the bottom of the handle 301, a spring 303 fixedly connected to one end of the slide plate 302, a fixing plate 304 fixedly connected to the end of the spring 303 away from the slide plate 302, and a locking pin 305 fixedly connected to the end of the slide plate 302 away from the spring 303. In the above design, the linear pulling force of the handle 301 is converted into the linear movement of the slide plate 302 to drive the locking pin 305 to disengage from the locked position.

[0023] The bottom of the fixing plate 304 is fixedly connected to the circumferential surface of the cylindrical plate 105. The surface of the fixing plate 304 is provided with a sliding groove, and the surface of the sliding plate 302 is slidably connected to the sliding groove on the surface of the fixing plate 304. The above design provides a stable installation base for the entire positioning device 3.

[0024] The end of the locking pin 305 away from the sliding plate 302 is located in a recessed hole on the circumferential surface of the rotating plate 201 near the cylindrical plate 105. In the above design, the circumferential fixation of the rotating plate 201 is achieved by the engagement of the locking pin 305 with the recessed hole, preventing it from rotating accidentally.

[0025] The baffle 108 has a groove on the side near the sleeve 107, and the bottom end of the cleaning brush 109 is set on the top surface of the adjusting plate 207. The above design, in cooperation with the slider 208, provides guidance and support for the radial movement of the adjusting plate 207, ensuring smooth movement.

[0026] In use, the cleaning device for the inner wall of heating pipes of this utility model first starts the motor 103 fixedly installed on the support plate 102. The output shaft of the motor 103 drives the connecting column 104 fixedly connected to it to rotate, thereby transmitting power to the cylindrical plate 105 fixedly connected to the connecting column 104. Then, the cylindrical plate 105 transmits the rotational motion to the sleeve 107 through the connecting rod 106 fixedly connected to its side. Thus, the sleeve 107 and the baffle 108 fixedly connected to one end of the sleeve 107 rotate synchronously as a whole. At the same time, the bottom end of the cleaning brush 109 is set on the top surface of the radially adjustable adjustment plate 207. Secondly, the side surface of the baffle 108 near the sleeve 107 is provided with a radial groove, and the groove slides stably in the radial direction with the adjustment plate 207. Therefore, when the sleeve 107 and the baffle 108 rotate, the power is ultimately transmitted to the cleaning brush 109 through the adjusting plate 207, driving it to rotate on the circumferential diameter that has been adjusted and determined, thereby effectively scrubbing or scraping off the deposits on the inner wall of the heating pipe and achieving the cleaning function.

[0027] Meanwhile, when it is necessary to adjust the cleaning range of the cleaning brush 109 to accommodate different pipe diameters, the rotating plate 201 is first manually rotated, so that the rotating plate 201 is positioned between the cylindrical plate 105 and the sleeve 107 and rotates through the sleeve. This rotation is then transmitted to the turntable 203 via the connecting plate 202 fixedly connected to its inner circumferential surface, causing the turntable 203 to rotate synchronously. Since the arc-shaped guide groove on the surface of the turntable 203 forms a sliding connection with one end of the rotating rod 204, as the turntable 203 rotates, the arc-shaped guide groove drives the rotating rod 204 to generate radial displacement. This causes the other end of the rotating rod 204 to be fixedly connected to the long rod 205, which passes through and is slidably connected to a limiting plate 206 fixed at one end to the inner circumferential surface of the sleeve 107. This limiting plate 206 constrains the long rod 205 to only perform linear motion and prevents it from rotating circumferentially with the sleeve 107. Therefore, the radial motion of the rotating rod 204 is precisely converted into the stable linear motion of the long rod 205. This causes the radial movement of the long rod 205 to directly push the adjusting plate 207 fixedly connected to one end to move synchronously, so that the five adjusting plates 207 are evenly distributed on the circumferential surface of the sleeve 107, and thus their synchronous radial movement achieves uniform adjustment of the cleaning diameter. At the same time, to ensure the linearity and stability of the movement of the adjusting plate 207, the slider 208 fixedly connected to one side is slidably connected in the radial groove opened on one side of the baffle 108, thereby ensuring the stability of the movement of the adjusting plate 207. This solves the problem that it is difficult to clean pipes of different diameters in a convenient way, resulting in poor device adaptability, inability to fit the inner wall of pipes of different diameters, incomplete cleaning, and increased subsequent maintenance costs.

[0028] Secondly, in the initial state: the spring 303 is in its natural state, and its elastic thrust continues to act on the slide plate 302, thereby pushing the slide plate 302 to slide along the groove opened on the fixed plate 304 fixedly connected to the circumferential surface of the cylindrical plate 105. This causes the locking pin 305, which is fixedly connected to one end of the slide plate 302, to be stably pushed into the corresponding recessed hole opened on the circumferential surface of the rotating plate 201 near the cylindrical plate 105. Thus, through the tight fit between the locking pin 305 and the recessed hole, the circumferential direction of the rotating plate 201 is reliably fixed, thereby locking the entire adjustment mechanism and preventing it from rotating unexpectedly due to vibration or force during the cleaning operation, ensuring the stability of the cleaning diameter. At the same time, the positioning device 3 enables the cylindrical plate 105 to rotate, driving the rotating plate 201 to rotate synchronously, thereby driving the adjustment plate 207 and the cleaning brush 109 set on the surface of the adjustment plate 207 to rotate, so that the cleaning brush 109 cleans the pipe. When adjustment is required, the handle 301 is manually pulled outward, causing the handle 301 to drive the slide plate 302, which is fixedly connected to it, to slide along the groove of the fixed plate 304 against the thrust of the spring 303. As the slide plate 302 moves, the spring 303 is compressed to store energy, so that the linear movement of the slide plate 302 directly drives the locking pin 305, which is fixedly connected to its other end, to disengage from the recess of the rotating plate 201. Once the locking pin 305 disengages from the recess, the circumferential constraint of the rotating plate 201 is released, and the rotating plate 201 can be freely rotated for adjustment. After adjustment, the handle 301 is released, and the elastic potential energy stored in the spring 303 is released, which automatically pushes the slide plate 302 and the locking pin 305 back to their original positions, so that the locking pin 305 engages in the recess on the circumference of the rotating plate 201 corresponding to the new position, thus locking and effectively preventing the cleaning diameter of the cleaning brush 109 from changing unexpectedly due to vibration or resistance during operation of the cleaning device 1.
