Description
Technical Field
[0001] This invention belongs to the field of cold water wall detection technology, specifically relating to a boiler component deformation measuring device. Background Technology
[0002] Water-cooled walls are the core heat-receiving components of boilers, primarily absorbing heat from the high-temperature flames and flue gas in the furnace, causing the working fluid (water or a water-steam mixture) inside the tubes to evaporate, while simultaneously protecting the furnace walls from high temperatures and erosion. However, water-cooled walls operate in a high-temperature, high-pressure environment, and after long-term use, problems such as expansion, deformation, dents, and rust inevitably occur. These deformations can lead to boiler malfunctions and safety hazards; therefore, it is necessary to regularly measure the deformation of the water-cooled walls.
[0003] Current methods for measuring cold water wall deformation primarily utilize wall-climbing robots. These robots use magnetic wheels to move along the surface of the cold water wall and are equipped with an electromagnetic ultrasonic thickness gauge and a camera. During measurement, an operator uses a control platform to maneuver the robot, which in turn moves the ultrasonic thickness gauge, measuring the cold water wall as it moves to determine where deformation has occurred. However, existing wall-climbing robots lack a marking function. After detecting deformation in a specific area, the robot cannot mark it, requiring the operator to record the deformed area. Given the large area of the cold water wall, this increases the difficulty of recording, and omissions or misrepresentations necessitate remeasurement, making the process cumbersome.
[0004] Therefore, it is necessary to design a markable deformation measuring device for boiler components to reduce the workload of deformation measurement. Summary of the Invention

The drawing pen draws a mark on the outer wall of the cold water wall, recording this area as the deformation area, which is convenient for subsequent maintenance. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0023] Example 1: like Figures 1 to 5As shown, a boiler component deformation measuring device includes: a wall-climbing robot, a marking component 2, and a measuring component 3; the wall-climbing robot includes a wall-climbing robot body and a control system, the wall-climbing robot body is electrically connected to the control system, and the wall-climbing robot body is equipped with magnetic wheels, a camera, a control module, a drive motor, etc. The control system is adapted to an operating terminal, and the movement of the wall-climbing robot body is controlled through the operating terminal; the marking component 2 includes a pen 21, a clamp 22, a first linear movement mechanism 23, and a support 24; one end of the support 24 is connected to the wall-climbing robot body, and the other end of the support 24 is connected to the fixed end of the first linear movement mechanism 23. The support 24 supports the first linear motion mechanism 23; the movable end of the first linear motion mechanism 23 is equipped with a clamp 22; the clamp 22 is connected to a paintbrush 21, and the first linear motion mechanism 23 drives the clamp 22 and the paintbrush 21 to move up and down so that the paintbrush 21 contacts the outer wall of the cold water wall. The paintbrush 21 is a paintbrush. The measuring component 3 includes an electromagnetic ultrasonic thickness gauge 31 and a connecting rod 32; one end of the connecting rod 32 is connected to the end of the support 24 away from the wall-climbing robot body, and the other end of the connecting rod 32 is equipped with an electromagnetic ultrasonic thickness gauge 31 to measure the thickness of the water-cooled wall; both the electromagnetic ultrasonic thickness gauge 31 and the first linear motion mechanism 23 are connected to the control system circuit. In addition, it should be noted that the wall-climbing robot body, the control system, and the electromagnetic ultrasonic thickness gauge are all existing technologies and are used in actual applications. The specific models of the wall-climbing robot body, the control system, the electromagnetic ultrasonic thickness gauge, and the first linear motion mechanism are not improvements of this application and will not be described in detail here.
[0024] like Figure 2 and Figure 3 As shown, preferably, the electromagnetic ultrasonic thickness gauge 31 and the drawing pen 21 are located in front of the wall-climbing robot body in the direction of travel; the drawing pen 21 is located between the electromagnetic ultrasonic thickness gauge 31 and the wall-climbing robot body, and the drawing pen 21 is located behind the electromagnetic ultrasonic thickness gauge 31 to correspond with the electromagnetic ultrasonic thickness gauge 31; the electromagnetic ultrasonic thickness gauge 31 is located below the support 24 to be close to the cold water wall.
[0025] Work style: In use, the operator controls the wall-climbing robot to walk on the cold water wall through the control system's operating terminal. During the movement of the wall-climbing robot, the electromagnetic ultrasonic thickness gauge 31 and the drawing pen 21 are moved. The electromagnetic ultrasonic thickness gauge 31 detects the thickness of the cold water wall during the movement. If the electromagnetic ultrasonic thickness gauge 31 detects a deformation problem in the thickness of the cold water wall, the operator can control the first linear movement mechanism 23 through the operating terminal to move the clamp 22 and the drawing pen 21 toward the outer wall of the cold water wall, so that the drawing pen 21 contacts the deformation area of the cold water wall. The drawing pen 21 draws a mark on the outer wall of the cold water wall, recording this area as the deformation area, which is convenient for subsequent maintenance, avoids omissions or confusion, and effectively reduces the workload of deformation measurement.
[0026] like Figure 2 and Figure 3 As shown, preferably, the measuring component 3 further includes a connecting frame 33, a roller brush 34, and a motor 35; the connecting frame 33 is connected to the end of the support 24 away from the wall-climbing robot body, optionally, the connecting frame 33 is a U-shaped frame; the roller brush 34 is rotatably mounted on the connecting frame 33; the length direction of the roller brush 34 is consistent with the width direction of the wall-climbing robot body; the motor 35 is mounted on the connecting frame 33; the output end of the motor 35 is mechanically connected to the roller brush 34, driving the roller brush 34 to rotate, optionally, the motor 35 is directly connected to the roller brush 34; the motor 35 is connected to the control system circuit; during the movement of the wall-climbing robot body, the connecting frame 33, the roller brush 34, and the motor 35 move together, the motor 35 drives the roller brush 34 to rotate, the roller brush 34 moves and rotates at the same time, cleaning the outer wall of the cold water wall, removing dust from the outer wall of the cold water wall, so as to remove the interference of dust and facilitate the pen 21 to make marks on the outer wall of the cold water wall.
[0027] Example 2: like Figure 2 and Figure 3 As shown, compared with Embodiment 1, the difference lies in that the marking component 2 further includes a second linear movement mechanism 25; the first linear movement mechanism 23 is connected to the support 24 through the second linear movement mechanism 25; the fixed end of the second linear movement mechanism 25 is disposed on the support 24; the extension and retraction direction of the second linear movement mechanism 25 is consistent with the width direction of the wall-climbing robot body; the fixed end of the first linear movement mechanism 23 is connected to the movable end of the second linear movement mechanism 25, and the second linear movement mechanism 25 drives the first linear movement mechanism 23 to move; the second linear movement mechanism 25 is connected to the control system circuit; when the first linear movement mechanism 23 moves the drawing pen 21 downward, the second linear movement mechanism 25 drives the first linear movement mechanism 23 to move left and right back and forth, and the drawing pen 21 moves left and right back and forth with the second linear movement mechanism 25 to expand the range of motion of the drawing pen 21, increase the movement of the drawing pen 21, and thus increase the range of the marking area, making it easier for staff to notice. In addition, it should be noted that the connection method between the second linear movement mechanism and the control system is a conventional connection, and the specific model of the second linear movement mechanism is not an improvement point of this application, so it will not be described in detail here.
[0028] like Figure 2 and Figure 3As shown, preferably, the marking component 2 further includes a third linear motion mechanism 26; the second linear motion mechanism 25 is connected to the first linear motion mechanism 23 via the third linear motion mechanism 26; the fixed end of the third linear motion mechanism 26 is disposed at the movable end of the second linear motion mechanism 25; the movable end of the third linear motion mechanism 26 is connected to the first linear motion mechanism 23; the extension and retraction direction of the third linear motion mechanism 26 is consistent with the length direction of the wall-climbing robot body; the second linear motion mechanism 25 drives the third linear motion mechanism 26 and the first linear motion mechanism 23 to move left and right, and the third linear motion mechanism 26 drives the first linear motion mechanism 23 to move back and forth; the third linear motion mechanism 26 is connected to the control system circuit; preferably, the first linear motion mechanism 23 and the third linear motion mechanism 26 are both electric push rods, with a small volume. Small and lightweight, and even better, the first linear motion mechanism 23 and the third linear motion mechanism 26 are both miniature electric actuators to reduce space volume. The second linear motion mechanism 25 is a lead screw slide, which has high flexibility and fast response speed, suitable for reciprocating motion. When the first linear motion mechanism 23 moves the drawing pen 21 downward, the third linear motion mechanism 26 drives the first linear motion mechanism 23 forward to expand the range of motion of the drawing pen 21, increase the movement of the drawing pen 21, and thus increase the range of the marking area, making it easier for the operator to notice. Preferably, the operating terminal is equipped with a marking button. After the marking button is pressed, the first linear motion mechanism 23, the second linear motion mechanism 25, and the third linear motion mechanism 26 automatically operate, moving the drawing pen 21 to complete the marking, thus reducing the operator's operation steps. In addition, it should be noted that the connection method between the third linear motion mechanism and the control system is a conventional connection. The specific model of the third linear motion mechanism is not an improvement point of this application and will not be described here.
[0029] like Figure 2 and Figure 3 As shown, preferably, the second linear movement mechanism 25 and the third linear movement mechanism 26 are located above the bracket 24 to provide installation space and movement space for the paintbrush 21 and the clamp 22.
[0030] Example 3: like Figures 2 to 7As shown, compared with Embodiment 1, the difference lies in the fact that a structural form of the clamp 22 is given. The clamp 22 includes a connecting plate 221, a sleeve 222, and a cover 223. One end of the connecting plate 221 is connected to the end of the first linear moving mechanism 23 away from the support 24. A through hole is opened on the plate surface of the connecting plate 221 for the pen tip of the corresponding pen 21. One end of the sleeve 222 is connected to the plate surface of the connecting plate 221, and the inner cavity of the sleeve 222 communicates with the through hole. The other end of the sleeve 222 is an open structure. The pen 21 is located inside the sleeve 222 and is detachably connected to the sleeve 222. The detachable connection is... Threaded connection; the tip of the pen 21 passes through the through hole and extends out of the sleeve 222; the cover 223 covers the end of the sleeve 222 away from the connecting plate 221; the sleeve 222 is located on the side of the connecting plate 221 near the fixed end of the first linear moving mechanism 23; the inner diameter of the sleeve 222 is larger than the diameter of the through hole; the axis of the sleeve 222 and the axis of the through hole are on the same straight line; the sleeve 222 and the cover 223 restrict the pen 21 to prevent the pen 21 from separating from the sleeve 222. When the pen 21 contacts the outer wall of the cold water wall, the cover 223 presses against the pen 21, so that the pen 21 contacts the outer wall of the cold water wall.
[0031] like Figure 7 As shown, preferably, the clamp 22 also includes a spring 224; the spring 224 is located inside the sleeve 222; one end of the spring 224 is connected to the cover 223, and the other end of the spring 224 presses against the top of the pen 21, pushing the pen 21 to move towards the through hole; because the outer wall of the cold water wall is not flat and smooth, but has curved parts, when the pen 21 contacts the curved part of the cold water wall, the spring 224 deforms, thereby changing the position of the pen tip of the pen 21, so that the pen 21 is always in contact with the outer wall of the cold water wall when making marks.
[0032] like Figure 2 , Figures 4 to 7 As shown, preferably, the marking component 2 further includes a deformable sleeve 27; one end of the deformable sleeve 27 is connected to the side of the connecting plate 221 away from the fixed end of the first linear moving mechanism 23; the inner cavity of the deformable sleeve 27 communicates with the through hole; the deformable sleeve 27 covers the tip of the brush 21, the deformable sleeve 27 is made of plastic and can deform, optionally, the deformable sleeve 27 is a telescopic plastic corrugated tube, which can deform, the deformable sleeve 27 covers the tip of the brush 21 to prevent the tip of the brush 21 from getting dusty when the roller brush 34 sweeps dust, and protects the tip of the brush 21.
[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
