Description

Technical Field

[0001] This utility model belongs to the field of boiler monitoring technology, specifically relating to a mobile, non-contact boiler expansion monitoring device. Background Technology

[0002] With the continuous development of industrial production, the operational reliability of boilers, as key heat energy conversion equipment, is of paramount importance. During boiler operation, due to the heating effect of the internal medium, uneven heating of different parts of the boiler body inevitably leads to thermal expansion.

[0003] Traditional boiler expansion monitoring equipment is mostly fixed installation, which has many drawbacks. For example, the installation is complicated, and fixed components need to be installed and debugged during the boiler construction or shutdown maintenance phase. It is not convenient to make flexible adjustments according to the actual operation of the boiler. In addition, some equipment has low monitoring accuracy and is prone to false alarms or missed alarms.

[0004] Furthermore, retrofitting existing boilers that are already in use without reserved monitoring interfaces is difficult and costly. While non-contact monitoring technology avoids the problems associated with contact to some extent, existing non-contact devices are often customized for specific boiler models, lacking versatility, inconvenient to move and install, and unable to flexibly meet the monitoring needs under different operating conditions, thus failing to meet the diverse and efficient operation and maintenance requirements of today's industrial sites.

[0005] Meanwhile, in the daily operation of boilers, in addition to routine fixed-point monitoring, there are often temporary special situations that require special attention to the expansion status of specific areas. For example, during the trial operation phase after partial modification or repair of the boiler, or when there is suspicion of potential abnormal expansion in a certain area, mobile monitoring equipment can be quickly deployed to the relevant parts to accurately capture expansion dynamics and provide key data in a timely manner, without having to pre-set a large number of monitoring points as in traditional methods, which would only increase costs and waste resources. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mobile, non-contact boiler expansion monitoring device. This device overcomes the defects of existing boiler expansion monitoring technology and enables convenient and rapid deployment of monitoring points without complex modifications to the boiler body. It acquires boiler expansion data in real time with high precision and non-contact, providing accurate data for boiler operation and maintenance, and improving boiler operation safety and management efficiency.

[0007] The purpose of this utility model is achieved as follows: a movable, non-contact boiler expansion monitoring device, comprising an expansion displacement measuring device, a movable mounting assembly, and a marker. The expansion displacement measuring device is fixedly mounted on the movable mounting assembly, and the marker is directly or indirectly mounted on the outer wall of the boiler to be monitored. During expansion monitoring, the expansion displacement measuring device and the marker are aligned. The movable mounting assembly can move the expansion displacement measuring device together to the designated monitoring point, and can also fix the movable mounting assembly to ensure the stability of the expansion displacement measuring device during the monitoring process.

[0008] Furthermore, the mobile installation assembly includes a base, on which a bracket is fixedly mounted, and a gimbal is mounted on the top of the bracket, with the expansion displacement measuring device mounted on the gimbal.

[0009] The base may be equipped with a moving mechanism to allow the device to move flexibly around the boiler, thereby quickly moving the expansion displacement measuring device to a designated expansion measuring point for real-time monitoring of the boiler's expansion.

[0010] Furthermore, a caster wheel assembly is provided at the bottom of the base, and the caster wheel assembly is a universal wheel; the universal wheel facilitates the turning operation of this device during movement.

[0011] Furthermore, the base is also provided with a support foot at the bottom, which is used to support the base on the ground and at the same time lift the moving wheel assembly off the ground; the moving wheel assembly can be lifted off the ground by the support foot.

[0012] Furthermore, the expansion displacement measuring device is a high-resolution industrial camera sensor used to accurately sense the minute expansion changes of the boiler, and the marker is an image marker composed of four sets of square patterns arranged in two rows and two columns with equal horizontal and vertical spacing.

[0013] Furthermore, the expansion displacement measuring device includes a high-definition industrial camera and a supplementary light source. The supplementary light source is used to provide supplementary lighting for the high-definition industrial camera when the lighting is poor, so as to ensure clear image recognition.

[0014] Furthermore, the connection between the marker and the outer wall of the boiler to be monitored adopts different fixing methods depending on the type of boiler. For boilers without insulation, magnetic materials are used to fix the marker to the outer wall of the boiler. For boilers with insulation, the marker is fixed to the channel steel leading out from the expansion measuring point by means of a clamp.

[0015] Furthermore, after the expansion displacement measuring device is aligned with the marker, the distance between the marker and the expansion displacement measuring device is 40~50cm.

[0016] Furthermore, it also includes an expansion indicator bracket connected to the boiler body under test, with an expansion indicator sleeve connected to the end of the expansion indicator bracket, and the marker disposed on the expansion indicator sleeve; the marker is indirectly connected to the boiler body under test through the expansion indicator bracket.

[0017] Furthermore, the expansion indicator sleeve is connected to an expansion indicator scale needle, and an expansion indicator dial is provided below the expansion indicator scale needle; when the boiler body under test expands and deforms during operation, the expansion change of the boiler body under test is visually displayed on the expansion indicator dial.

[0018] The beneficial effects of this utility model are as follows: This utility model provides a movable, non-contact boiler expansion monitoring device, which consists of an expansion displacement measuring device, a movable mounting assembly, and a marker. The expansion displacement measuring device is fixedly mounted on the movable mounting assembly, and the marker is directly or indirectly mounted on the outer wall of the boiler to be monitored. During expansion monitoring, the expansion displacement measuring device and the marker are aligned. The movable mounting assembly can move the expansion displacement measuring device to the designated monitoring point. Once at the designated monitoring point, the expansion displacement measuring device can be used for monitoring. The movable installation component is fixed to ensure the stability of the expansion displacement measuring device during monitoring. The expansion displacement measuring device is aligned with the marker. After the boiler body to be monitored expands and deforms, the marker moves along with it and can be monitored by the expansion displacement measuring device. This utility model provides a movable, non-contact boiler expansion monitoring device that allows for convenient and rapid deployment of monitoring points without complex modifications to the boiler body. It acquires boiler expansion data in real time with high precision and non-contact, providing accurate data for boiler operation and maintenance, and improving boiler operation safety and management efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0027] like Figure 1-2 As shown, this utility model discloses a movable, non-contact boiler expansion monitoring device, comprising an expansion displacement measuring device 7, a movable mounting assembly, and a marker 6. The expansion displacement measuring device 7 is fixedly mounted on the movable mounting assembly. The marker 6 is directly or indirectly mounted on the outer wall of the boiler to be monitored, and the expansion displacement measuring device 7 and the marker 6 are aligned during expansion monitoring operations. The movable mounting assembly can move the expansion displacement measuring device 7 together to the designated monitoring point, and can also fix the movable mounting assembly to ensure the stability of the expansion displacement measuring device 7 during the monitoring operation.

[0028] Different types and specifications of boilers have varying structural layouts and thermal expansion characteristics. Fixed-installation monitoring devices are customized for specific boilers, and once installed, they are difficult to change. They are almost unusable when boilers are upgraded, processes are adjusted, or monitoring point requirements change. Mobile installation methods, on the other hand, easily address these challenges. Simply move the monitoring device to a new critical location and adjust parameters such as the height, angle, and position of the mounting bracket to adapt to new operating conditions. One device can serve multiple boilers, offering strong versatility and reducing equipment investment costs.

[0029] Furthermore, in one embodiment, the mobile installation assembly includes a base 10, on which a bracket 9 is fixedly mounted, and a gimbal 8 is mounted at the top of the bracket 9, with the expansion displacement measuring device 7 mounted on the gimbal 8.

[0030] The base 10 may be equipped with a movable mechanism at its bottom, which allows the device to move flexibly around the boiler, thereby quickly moving the expansion displacement measuring device 7 to the designated expansion measuring point for real-time monitoring of the boiler's expansion. After moving the expansion displacement measuring device 7 to the designated expansion measuring point, the height of the expansion displacement measuring device 7 can be adjusted by adjusting the overall height of the bracket 9 to correspond to the height of the marker 6. At the same time, the angle of the expansion displacement measuring device 7 can be further finely adjusted by the gimbal 8 to ensure its levelness and alignment with the marker 6.

[0031] Furthermore, in one embodiment, the base 10 is provided with a movable wheel assembly 11 at its bottom, which can provide support for the device and facilitate the rapid movement of the device on the ground. The movable wheel assembly 11 is a universal wheel. The universal wheel facilitates the turning operation of the device during movement, further ensuring its speed and stability in movement and turning.

[0032] Furthermore, in one embodiment, the base 10 is also provided with a support foot 12 at its bottom. The support foot 12 is used to support the base 10 on the ground and simultaneously lift the moving wheel assembly 11 off the ground. After the device is moved to the designated boiler expansion monitoring point with the support of the moving wheel assembly 11 on the base 10, the moving wheel assembly 11 can be lifted off the ground by the support foot 12, so that the support foot 12 directly supports the base 10 to ensure the stability of the device during the monitoring operation.

[0033] Furthermore, the support foot 12 is connected to the base 10 by bolts. By tightening the bolts, the height of its lower end from the ground can be adjusted. After the device is moved to the designated boiler expansion monitoring point with the support of the base 10 by the moving wheel assembly 11, the bolts are tightened until its lower end is supported on the ground, and the casters 11 are lifted off the ground. At the same time, the base 10 is kept level, which can achieve the fixation and stable support of the device and ensure the stability of the expansion displacement measuring device 7 in the expansion monitoring operation.

[0034] Furthermore, in one embodiment, the expansion displacement measuring device 7 is a high-resolution industrial camera sensor used to accurately sense minute expansion changes in the boiler and monitor the boiler's expansion in real time. The marker 6 is as follows: Figure 2 The image shown consists of four sets of square patterns arranged in two rows and two columns with equal horizontal and vertical spacing. The side length of the large square formed by the centroids of the four squares is L.

[0035] Furthermore, in one embodiment, the expansion displacement measuring device 7 includes a high-definition industrial camera and a supplementary light source. The supplementary light source is used to provide supplementary lighting for the high-definition industrial camera when the lighting is poor, so as to ensure clear image recognition and thus ensure the accuracy of expansion monitoring.

[0036] Furthermore, in one embodiment, the connection between the marker 6 and the outer wall of the boiler to be monitored adopts different fixing methods depending on the type of boiler. For boilers without insulation, magnetic materials are used to fix the marker 6 to the outer wall of the boiler. For boilers with insulation, the marker 6 is fixed to the channel steel leading out from the expansion measuring point by means of a clamp.

[0037] Furthermore, in one embodiment, after the expansion displacement measuring device 7 is aligned with the marker 6, the distance between the marker 6 and the expansion displacement measuring device 7 is 40~50cm; after adjusting the distance between the marker 6 and the expansion displacement measuring device 7, the base 10 is fixed by the support foot 12.

[0038] Furthermore, in one embodiment, it also includes an expansion indicator bracket 2 connected to the boiler body 1 under test. An expansion indicator sleeve 3 is connected to the end of the expansion indicator bracket 2, and the marker 6 is disposed on the expansion indicator sleeve 3. The marker 6 is indirectly connected to the boiler body 1 under test through the expansion indicator bracket 2. When the boiler body 1 under test expands and deforms during operation, it will be sensitively reflected on the marker 6 through the expansion indicator bracket 2 and monitored by the expansion displacement measuring device 7.

[0039] Furthermore, in one embodiment, the expansion indicator sleeve 3 is connected to an expansion indicator needle 5, and an expansion indicator dial 4 is provided below the expansion indicator needle 5; when the boiler body 1 under test expands and deforms during operation, the expansion indicator needle 5 will be moved by the expansion indicator bracket 2 and the expansion indicator sleeve 3, and then marked on the expansion indicator dial 4, so as to visually display the expansion change of the boiler body 1 under test.

[0040] Furthermore, in one embodiment, a data processing device 13 is provided on the base 10. The data processing device 13 is connected to the expansion displacement measuring device 7 to process and analyze the monitoring data. When the monitored expansion value exceeds a preset threshold, an alarm signal can be issued through an alarm device. The data processing device 13 can process and store the monitoring data in real time and transmit the data to a remote monitoring terminal wirelessly.

[0041] Furthermore, in one embodiment, the expansion displacement measuring device 7 employs an industrial camera with low illumination and a high frame rate (not less than 30fps) and a resolution of 3840×2160. The sensor type is 1 / 1.8" ProgressiveScan CMOS, paired with a 3.2mm wide-angle lens, which can cover a large area of ​​the boiler surface. It transmits the image to the data processing device 13, which uses advanced image recognition algorithms to analyze the acquired continuous image frames and calculate the three-dimensional spatial changes of the expansion markers, i.e., the boiler expansion changes.

[0042] In summary, this utility model discloses a movable, non-contact boiler expansion monitoring device, comprising an expansion displacement measuring device 7, a movable mounting assembly, and a marker 6. The expansion displacement measuring device 7 is fixedly mounted on the movable mounting assembly, and the marker 6 is directly or indirectly mounted on the outer wall of the boiler to be monitored. During expansion monitoring, the expansion displacement measuring device 7 and the marker 6 are aligned. The movable mounting assembly can move the expansion displacement measuring device 7 to a designated monitoring point. Once at the designated monitoring point, the expansion displacement measuring device 7 can be moved. The movable installation components are fixed to ensure the stability of the expansion displacement measuring device 7 during the monitoring operation. The expansion displacement measuring device 7 is aligned with the marker 6. After the boiler body to be monitored expands and deforms, the marker 6 moves along with it and can be monitored by the expansion displacement measuring device 7. This utility model provides a movable, non-contact boiler expansion monitoring device that can conveniently and quickly deploy monitoring points without complex modifications to the boiler body. It can acquire boiler expansion data in real time with high precision and non-contact method, providing accurate basis for boiler operation and maintenance, and improving boiler operation safety and management efficiency.
