Description

Technical Field

[0001] This invention relates to the field of power plant boiler technology, and in particular to a boiler pipeline monitoring system and inspection and cleaning device. Background Technology

[0002] Boiler piping refers to the network of pipes in a boiler system responsible for transporting media (such as water, steam, fuel, etc.). They connect different parts of the boiler and related equipment, serving to transmit, distribute, and recover the media. Boiler piping transports media such as water, steam, and fuel from one component or piece of equipment to another. Besides connecting other equipment, boiler piping also transports water from the feedwater system to the boiler, and the main steam pipeline transfers steam from the boiler to process equipment or heat exchangers. Boiler piping also functions to recover and reuse used media and is typically equipped with various control valves, instruments, and regulating devices to control the flow rate, pressure, and temperature of the media, ensuring the safe operation of the boiler system and meeting process requirements.

[0003] However, during the use of boiler pipelines, blockages can easily occur due to the accumulation and caking of particulate impurities. As the internal pressure of the pipeline increases, this can even lead to gas or liquid leaks, or even pipeline explosions and cracks. Existing technologies lack systems for real-time and accurate monitoring of boiler pipelines.

[0004] At the same time, after the monitoring system issues a pipeline fault alarm, it needs to investigate the internal condition of the pipeline. Blockages inside the pipeline prevent the inspection camera from entering, and deposits on the inner wall of the pipeline will adhere to the inner wall, hindering the observation of cracks and deformations in the inner wall of the pipeline.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1 Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a boiler pipeline monitoring system that can monitor the boiler tubes in real time online, realize early prediction of pipeline leaks, and determine the location and extent of the leak area.

[0031] Specifically, the boiler pipeline monitoring system includes a signal acquisition device, a monitoring device, and an automatic ash removal and anti-clogging device. The signal acquisition device consists of several enhanced acoustic signal sensors and waveguides. The waveguides are Y-shaped and fixed to the boiler wall to provide an acoustic signal channel. The enhanced acoustic signal sensors are fixed at one end of the waveguide to collect the acoustic signals transmitted through the waveguide from inside the boiler. The monitoring device is located in the central control room and consists of an industrial control host, multiple leak detection hosts, a display, a data output device, and a local relay junction box. The display, data output device, and each leak detection host are connected to the industrial control host for transmission. The signals from the enhanced acoustic signal sensors are transmitted to the corresponding leak detection hosts through the local relay junction box.

[0032] The air compressor is connected to another port on the upper part of each waveguide through a pipeline. Each pipeline is equipped with a solenoid valve, which is controlled by a solenoid valve control box, which is controlled by the corresponding leak detection host. The monitoring device has a real-time monitoring unit, a historical query unit, an alarm unit, and a remote communication unit.

[0033] Preferably, the real-time monitoring unit utilizes a multi-channel high-speed data acquisition card to sample and convert the signals transmitted from the acoustic signal sensor into digital signals. These signals are then sent to the main processing board via a bus. After mathematical operations such as FFT transformation, key physical quantities representing the degree of leakage are obtained and displayed in bar charts and trend graphs. Tracking changes in the bar charts and trend graphs allows for prediction and alarm of the leakage situation. Additionally, processing the background noise data at the measurement points allows for the determination of whether the waveguide is clogged with ash. A digital input / output card, interlocked with the sootblower, monitors the sootblower's operation. The unit can perform self-tests to determine if the system is functioning correctly; it also has passive node outputs that connect to the control room's indicator light for alarm indication.

[0034] Even better, the historical query unit has a historical recall function, which allows for data analysis by querying historical trend charts and historical reports.

[0035] In summary, during operation, the alarm unit can identify the location of leaks and ash blockages through the furnace simulation diagram on the software interface. When a leak is detected in a furnace tube near a certain measuring point, different alarm displays will appear depending on the degree of leakage. After a delay, a switch signal will be output to the indicator light for alarm. When the acoustic wave conduction tube is blocked with ash, maintenance personnel can also perform corresponding maintenance based on the prompts. The remote communication unit can remotely analyze the furnace noise data on the client side according to user needs, assisting in determining whether a leak has occurred and the degree of leakage, and adjusting relevant parameters accordingly.

[0036] Example 2 Reference Figures 1-6 This is the second embodiment of the present invention. This embodiment provides an inspection and cleaning device, which controls the cleaning component K-5 to rotate and clean by the moving component K-3, thereby cleaning the blockage on the inner wall of the pipe.

[0037] Specifically, the cleaning device is characterized by: including a boiler pipeline monitoring system as described in any one of claims 1 to 3; a conveying mechanism 100, including a conveying pipe 101, a discharge port 102 disposed above the conveying pipe 101, a swing plate 103 rotatably disposed on the inner wall of the conveying pipe 101, a grinding block disposed on the inner wall of the conveying pipe 101, and a sieve plate 104 slidably disposed on the inner wall of the conveying pipe 101; and an adjusting mechanism 200, including a movable frame 201 disposed on both ends of the swing plate 103, an adjusting component 202 disposed on the inner wall of the movable frame 201, and a drive motor 203 disposed on the end face of the adjusting component 202; and an oscillation mechanism 300, including a universal joint 301 disposed on the end face of the adjusting component 202, and a sleeve The system includes a first transmission belt 301a on the outer wall of the universal joint 301, a transmission shaft 302 on the inner wall of the first transmission belt 301a, and an oscillation assembly 303 on the end face of the transmission shaft 302; a dredging mechanism 400, including a guide wheel 401 on the inner wall of the second transmission belt 301b, a dredging pipe 402 on the outer wall of the conveying pipe 101, and a dredging assembly 403 slidably disposed on the inner wall of the dredging pipe 402; and a dust removal mechanism K, including a movable wheel K-1 movably disposed on the inner wall of the conveying pipe 101, a housing K-2 disposed on the end face of the movable wheel K-1, a movable assembly K-3 movably disposed on the inner wall of the housing K-2, a camera K-4 disposed on the end face of the movable assembly K-3, and a cleaning assembly K-5 respectively disposed on the end face of the movable assembly K-3.

[0038] The movable component K-3 includes a movable groove K-6 that runs through the housing K-2, a guide plate K-7 that is located on the outer wall of the housing K-2, a movable column K-8 that is slidably located on the inner wall of the movable groove K-6, a rotating plate K-9 located on the end face of the movable column K-8, a movable shaft K-10 located on the end face of the rotating plate K-9, a connecting cylinder K-11 located on the outer wall of the rotating plate K-9, a movable sleeve K-12 that is movably located on the outer wall of the movable shaft K-10, and an eccentric rotating shaft K-13 that is eccentrically located on one end face of the movable sleeve K-12. The guide plate K-7 is rectangular in shape and has the same shape as the movable groove K-6. The movable column K-8 is slidably located between the movable groove K-6 and the guide plate K-7.

[0039] Preferably, the cleaning assembly K-5 includes hydraulic dampers K-14 arrayed on the outer wall of the connecting cylinder K-11 and a cleaning block K-15 movably sleeved on the telescopic end of the hydraulic damper K-12; the cleaning block K-13 is bonded with a scouring pad, the movable sleeve K-12 includes a bracket K-16 and a rotating cylinder K-17 rotatably disposed on the inner wall of the bracket K-16, and the eccentric rotating shaft K-13 is fixedly disposed on the outer wall of the bracket K-16.

[0040] Furthermore, a rotating motor is rotatably installed on the end face of the housing K-2, and the output end of the rotating motor is simultaneously connected to the moving wheel K-1 and the eccentric rotating shaft K-13. The moving wheel K-1 is set on each end face of the housing K-2 through damping rods, so that the device can have sufficient driving power at various angles and can adapt to pipe environments of various shapes. The housing K-2 is cylindrical in shape, and the connecting cylinder K-11 is slidably installed on the inner wall of the housing K-2. There are two rotating cylinders K-17, and the moving shaft K-10 is slidably installed in the gap between the two rotating cylinders K-17 and can move freely in the gap. Different mesh sizes of scouring pads can be glued to the cleaning block K-13 to achieve different cleaning effects and facilitate disassembly and replacement.

[0041] In summary, during use, the entire Jiang device is placed on the inner wall of the pipe to be cleaned and observed. The servo motor is activated, driving the moving wheel K-1 to rotate, propelling the device deeper into the pipe. Simultaneously, the eccentric shaft K-13 rotates, causing the movable sleeve K-12 to rotate eccentrically. Since the rotating drum K-17 is rotatably mounted on the inner wall of the bracket K-16, the moving shaft K-10, which slides between the two rotating drums K-17, also rotates eccentrically, simultaneously causing the rotating plate K-9 and the moving column K-8 to slide along a rectangular path in the moving groove K-6. When the moving column K-8 slides axially, it drives the cleaning component K-5 to slide forward. Subsequently, when the moving column K-8 slides perpendicular to the axial direction, the cleaning component K-5 rotates radially. Thus, the cyclic sliding of the moving column K-8 achieves the reciprocating scraping cleaning of the cleaning component K-5, thereby realizing the cleaning function. After cleaning is complete, the camera K-4 captures and transmits images of the inner wall of the pipe, allowing users to easily observe the condition of the pipe's inner wall. Example 3 Reference Figures 1-4 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the adjustment mechanism 200 can start different working states at different times when the coal ash flow rate is different, thereby automatically realizing the three functions of unblocking mechanism 400: unblocking blockage, low-speed oscillation, and high-speed oscillation.

[0042] Specifically, the adjustment assembly 202 includes an adjustment rod 202a disposed on the inner wall of the movable frame 201, a slider 202a-1 disposed on the end face of the adjustment rod 202a, an output shaft 202b disposed on the output end of the transmission motor 203, a transmission gear 202b-1 sleeved on the output shaft 202b, a first driven gear 202c-1, a second driven gear 202c-2 and a third driven gear 202c-3 respectively meshing with the transmission gear 202b-1, an adjustment block 202d rotatably disposed on the outer wall of the output shaft 202b, and an adjustment groove 202d-1 disposed on the end face of the adjustment block 202d.

[0043] Preferably, the slider 202a-1 is slidably disposed on the inner wall of the adjusting groove 202d-1, and the end faces of the second driven gear 202c-2 and the third driven gear 202c-3 are provided with internal meshing gears 202c-4 for connection, and the end face of the internal meshing gears 202c-4 is connected to the universal joint 301.

[0044] Furthermore, a second transmission belt 301b is also fitted on the outside of the first driven gear 202c-1. The first transmission belt 301a slides through the guide wheel 401. The guide wheel 401 is fixedly installed on the outer wall of the conveying pipe 101. The rotating shaft 401a is fixedly connected to the rotating shaft of the guide wheel 401. The rotating shaft 401a is connected to the unblocking component 403 through the universal joint 301.

[0045] Preferably, the inner wall of the conveying pipe 101 is treated with high temperature resistance and leak-proof treatment. The swing plate 103 is rotatably mounted on the inner wall of the conveying pipe 101 through the bearing, and the rotating shaft of the swing plate 103 extends through the bearing to the outside of the conveying pipe 101. The two ends of the rotating shaft of the swing plate 103 are fixedly connected to the inner wall of the moving frame 201 respectively. The rotating shaft of the swing plate 103 and the outer wall of the conveying pipe 101 are provided with a spring-loaded buffer, so that the swing plate 103 is perpendicular to the inner wall of the conveying pipe 101 in a weightless state. The universal shaft 301 is a universal drive shaft in the prior art. The second drive belt 301b, guided by the guide wheel 401, transmits power through the universal shaft 301 to the unblocking component 301 to realize the unblocking function. There are three first drive belts 301a. The power of the drive motor 203 is transmitted to the drive shaft 302 through the universal shaft 301 and the three first drive belts 301a to drive the vibration mechanism 300 to work.

[0046] More preferably, there are three transmission gears 202b-1, which mesh with the first driven gear 202c-1, the second driven gear 202c-2, and the third driven gear 202c-3 respectively, and have the same tooth width. When the first driven gear 202c-1 is fully meshed with the first second driven gear 202c-2, the second driven gear 202c-2 and the third driven gear 202c-3 are both located at the end of the corresponding second driven gear 202c-2 away from the first driven gear 202c-1. Furthermore, the transmission gears corresponding to the driven gears mesh with the first driven gear 202c-1 with a tooth width equal to one tooth width. The gears are wide and have twice the tooth width. The second driven gear 202c-2 and the third driven gear 202c-3 are each connected to a pinion with the same number of teeth. These two pinions mesh with the internal meshing gear 202c-4 at the same time, so that the second driven gear 202c-2 and the third driven gear 202c-3 jointly drive the internal meshing gear 202c-4 to rotate. When one of the transmission gears drives the internal meshing gear 202c-4 to rotate, the other driven gear is in an idle state. The number of teeth of the second driven gear 202c-2 is greater than the number of teeth of the third driven gear 202c-3.

[0047] Furthermore, the unblocking component 403 is a threaded stainless steel pointed rod, and the vibration component 303 is an electric screener in the prior art, which realizes automatic vibration screening by rotating a motor.

[0048] In summary, during normal operation, the second driven gear 202c-2 meshes with the transmission gear 202b-1, thereby driving the oscillating assembly 303 to oscillate and screen the coal ash. When the amount of material discharged from the conveying pipe 101 increases, the falling coal ash pushes the swing plate 103 to deflect again, causing the moving frame 201 to rotate. At this time, the adjusting rod 202a drives the adjusting block 202d to slide in the adjusting groove 202d-1, while simultaneously pushing the adjusting groove 202d-1 towards the transmission motor 203. At this time, the second driven gear 202-2 disengages from the transmission gear 202b-1, and at the same time, the third driven gear 202-3 approaches and engages with the transmission gear 202c-1. 02b-1, due to the decrease in the number of teeth, the rotational speed increases, which drives the internal meshing gear 202c-4 to increase its rotational speed, thereby increasing the rotational speed of the first transmission belt 301a, which in turn increases the working frequency of the oscillation component 303 and the screening rate. At the same time, when the coal ash at the front end of the conveying pipe 101 is blocked, the amount of coal ash entering the subsequent process decreases. At this time, the swing plate 103 moves in the opposite direction and causes the first driven gear 202c-1 to mesh with the transmission gear 202b-1, driving the second transmission belt 301b to rotate, thereby driving the stainless steel tip rod to rotate along the thread and insert into the blocked coal ash, and crush it, thereby clearing the blockage. After clearing the blockage, the system automatically returns to normal operation.

[0049] Example 4 Reference Figures 1-5 This is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the oscillation component 303 can adjust the oscillation stroke. When the stroke is large enough, large particles are screened and oscillated, bounced up and collided with the grinding blocks on the inner wall of the conveying pipe 101 to break them, preventing blockage while performing preliminary crushing, which facilitates subsequent screening.

[0050] Specifically, the oscillation assembly 303 includes a turntable 303a disposed on the end face of the transmission shaft 302, a first ball head 303a-1 rotatably disposed on the end face of the turntable 303a, a connecting rod 303b disposed on the outer wall of the first ball head 303a-1, a second ball head 303b-1 disposed on the end face of the connecting rod 303b, a sleeve 303c movably sleeved on the outer wall of the second ball head 303b-1, a sliding plate 303c-1 disposed on the end face of the sleeve 303c, a fixed plate 303d sleeved on the outer wall of the transmission shaft 302, a sliding column 303d-1 disposed on the end face of the fixed plate 303d, an oscillation plate 303d-2 slidably sleeved on the outer wall of the sliding column 303d-1, and a sliding groove 303d-3 disposed on the end face of the oscillation plate 303d-2.

[0051] The sliding plate 303c-1 is slidably disposed on the inner wall of the sliding groove 303d-3, and the outer wall of the sliding column 303d-1 is fitted with a first elastic element 303d-4. The two ends of the first elastic element 303d-4 are respectively connected to the fixed plate 303d and the vibrating plate 303d-2. The sliding column 303d-1 is fixedly disposed on the outer wall of the conveying pipe 101, and the vibrating plate 303d-2 is fixedly connected to the screen plate 104.

[0052] Furthermore, the inner wall of the sliding groove 303d-3 is provided with a screw 303e that rotates through the sliding plate 303c-1 and the screw 303e is connected to the sliding plate 303c-1 by internal and external threads. A hand valve 303e-1 is provided on the side of the screw 303e away from the sliding plate 303c-1. The screen plate 104 only allows fine coal ash to pass through.

[0053] Preferably, the sieve plate 104 is slidably disposed on the inner wall of the conveying pipe 101 and the outer periphery is sealed. The first elastic element 303d-4 is a spring, which provides buffering while limiting the stroke of the oscillation mechanism. The sliding plate 303c-1 has an internal thread and is matched and screwed into the screw 303e. The first ball head 303a-1 is movably sleeved on the turntable 303a away from the center.

[0054] In summary, during use, the rotation of the drive shaft 302 drives the first ball head 303a-1, which is eccentrically mounted, to rotate. This, in turn, drives the second ball head 303b-1 to rotate via the connecting rod 303b, simultaneously causing the sleeve 303c to move up and down. This, in turn, causes the vibrating plate 303d-2 to move up and down, which in turn causes the connected screen plate 104 to vibrate. Fine coal ash particles on the screen plate are vibrated and fall from the screen plate 104, flowing out from below. Larger coal ash particles flow out from the screen plate 104. When it is necessary to change the vibration... During the process, rotating the hand valve 303e-1 causes the screw 303e to rotate, and the sliding plate 303c-1, which is threaded with it, moves closer to the disc 303a. This reduces the eccentricity of the first ball head 303a-1 and the second ball head 303b-1, thereby reducing the rotation radius of the sleeve 303c, i.e., the lifting frequency, but increasing the vertical lifting amplitude. When the stroke is large enough, large particles are screened, vibrated, and bounced up, and collide with the grinding blocks on the inner wall of the conveying pipe 101 to break them. This prevents blockage and performs preliminary crushing, which facilitates subsequent screening.

[0055] Example 5 Reference Figures 1-6 This is the fifth embodiment of the present invention. This embodiment is based on the previous embodiment, except that the unblocking component 403 can change the unblocking range, and the drill bit 403e increases the unblocking effect.

[0056] Specifically, the unblocking component 403 includes a control plate 403a located on the end face of the universal joint 301, a control groove 403a-1 located on the end face of the control plate 403a, a control block 403b slidably located on the end face of the control groove 403a-1, a threaded rod 403b-1 rotatably located inside the control block 403b, and a rotating head 403b-2 located on the end face of the threaded rod 403b-1. The threaded rod 403b-1 is rotatably located on the inner wall of the control groove 403a-1 via a bearing.

[0057] The unblocking component 403 also includes a disc 403c disposed on the end face of the control block 403b-2, an arc groove 403c-1 disposed on the end face of the disc 403c, a cylinder 403c-2 rotatably disposed on the inner wall of the arc groove 403c-1, and a lifting plate 403d disposed on the end face of the cylinder 403c-2.

[0058] Furthermore, the unblocking component 403 also includes a rotating column 403d-1 disposed on the end face of the lifting plate 403d, an arc-shaped groove 403d-2 disposed on the outer wall of the rotating column 403d-1, a fixed column 403d-3 slidably disposed on the inner wall of the arc-shaped groove 403d-2, and a drill bit 403e disposed on the end face of the rotating column 403d-1. A fixed block 403f is connected to the end face of the fixed column 403d-3. The fixed block 403d is rotatably sleeved on the outer wall of the rotating column 403d-1 and fixedly disposed on the inner wall of the unblocking pipe 402.

[0059] Preferably, the end of the unblocking pipe 402 located inside the conveying pipe 101 is provided with a flip cover to prevent coal ash from flowing out of the unblocking pipe 402. The disc 403c connected to the control block 403b is eccentrically set with the rotating shaft of the control plate 403a. The rotating column 403d-1 is transferred to the end face of the lifting plate 403b through the bearing. The drill bit 403e is conical in shape and has spiral patterns on its outer wall.

[0060] In summary, during use, the universal joint 301 drives the control plate 403a to rotate, causing the eccentrically positioned disc 403c on the control plate 403a to rotate. This causes the cylinder 403c-2 to slide inside the arc groove 403c-1, simultaneously moving the connected lifting plate 403d up and down. This, in turn, causes the rotating column 403d-1 to rise and fall simultaneously. At this time, the fixed column 403d-3 slides along the arc groove 403d-2, causing the rotating column 403d-1 to rotate. The fixed column 403d-3 is located on the end face of the rotating column 403d-1. The drill bit 403e rotates as it rises and falls, repeatedly pushing into the clogged coal ash and slag to break it up and clear the blockage. At the same time, the rotating head 403b-2 rotates, causing the threaded rod 403b- to rotate, which moves the control plate 403b away from the center of the disc 403c. This increases the eccentric rotation amplitude of the disc 403c, increases the rising and falling amplitude of the lifting plate 403d, and increases the reciprocating stroke of the drill bit 403e, thereby clearing the blockage of coal ash and slag deeper into the blockage.
