[0002] The Internet of Things (IoT) is a network that connects any object to the internet through information sensing devices and according to agreed-upon protocols, enabling information exchange and communication to achieve intelligent identification, location, tracking, monitoring, and management. In simple terms, the IoT is the "internet of interconnected things," encompassing two meanings: First, the IoT is an extension and expansion of the internet, with the internet remaining its core and foundation; second, the users of the IoT include not only people but also objects, enabling the exchange and communication of information between people and objects, as well as between objects themselves.

[0003] Existing integrated boilers monitor expansion using mechanical boiler expansion indicators, requiring manual patrols and data recording for analysis. These boiler expansion sensors cannot transmit acquired data to the monitoring system in a timely manner, preventing the system from obtaining boiler expansion data promptly. This can affect the safe operation of the boiler, potentially leading to cracks or leaks. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an integrated boiler expansion IoT sensor to solve the technical problem that existing boiler expansion sensors cannot transmit the acquired data to the monitoring system in a timely manner, thus preventing the monitoring system from timely obtaining the boiler expansion data, which affects the safe operation of the boiler and may lead to cracks or leaks.

[0005] According to the technical solution provided in the embodiments of this application, an integrated boiler expansion IoT sensor includes a fixed box, which is fixedly installed on the boiler on the right side by bolts, and has a mounting hole on the left side. An indicator rod is movably installed in the mounting hole, and the bottom of the indicator rod abuts against a scale plate for measuring the boiler expansion. The first displacement sensor is installed at the middle position between the indicator rod and the sliding sleeve, and is used for measuring the vertical displacement of the indicator rod; The second displacement sensor is installed at the bottom of the indicator rod and the bottom of the scale plate, and is used to measure the horizontal displacement of the indicator rod. An antenna is snapped onto the first connection port on the right side of the fixed box and is used for IoT transmission of detection data within the fixed box. A buzzer and a warning light are mounted side-by-side on the top of the fixed box for voice and light alerts regarding boiler expansion exceeding limits.

[0006] Furthermore, the fixed box has a rectangular structure and a microcontroller is installed inside.

[0007] Furthermore, a battery compartment is provided at the bottom of the fixed box, and batteries are installed in the battery compartment and sealed by a cover plate.

[0008] Furthermore, the left side of the fixing box is provided with parallel and corresponding connecting lugs along the vertical direction, so that each connecting lug is fixed to the outer wall of the boiler by corresponding bolts.

[0009] Furthermore, the rear end of the fixed box is provided with a plurality of first connection ports, which are arranged side by side and spaced apart along the horizontal direction.

[0010] Furthermore, corresponding first and second connecting lines are snapped onto the two first connecting ports located on the left side, with the other end of the first connecting line connected to the second connecting port at the top of the indicator rod, and the other end of the second connecting line connected to the third connecting port on the side of the scale plate.

[0011] Furthermore, a resistance sensing plate is provided at the bottom of the scale plate.

[0012] Furthermore, the scale plate is mounted on the base plate, and a support frame is installed at the bottom of the base plate to support the base plate.

[0013] Furthermore, the support frame has a triangular structure.

[0014] Furthermore, the fixing box is made of insulating material.

[0015] In summary, the beneficial effects of this application are as follows: 1. By setting a first displacement sensor and a second displacement sensor at the middle and bottom of the indicator rod of a traditional mechanical expansion indicator, the vertical and horizontal displacements of the boiler detected by the indicator rods of the first and second displacement sensors are dynamically sensed and recorded. The data is then transmitted to a microcontroller via a first and second connecting line in a timely manner. After data integration on the microcontroller, the data is transmitted to the monitoring system via an Internet of Things network. This allows for timely monitoring and early warning of the boiler's expansion data, thereby improving the safety of boiler operation. Second, by installing a buzzer and warning light on the top of the fixed box of the IoT sensor, the buzzer and warning light can promptly sound an alarm and flash a light to warn of boiler expansion exceeding the range based on the data output by the microcontroller. This makes it easier for patrol personnel to promptly obtain the location of the expansion and deal with the boiler overload, thereby improving the safety of boiler operation.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] An integrated boiler expansion IoT sensor, its structure is as follows: Figures 1-5 As shown, the device includes a fixed box 100, which has a rectangular structure and is made of insulating material. A corresponding connecting lug 110 is installed on the right side of the fixed box 100 so that the connecting lug 110 is fixed to the boiler by bolts, thereby making the left side of the fixed box 100 abut against the boiler wall. An installation hole is provided on the left side of the fixed box 100, and an indicator rod 200 is movably installed in the installation hole. The bottom of the indicator rod 200 abuts against the scale plate 300 so that the fixed box 100 moves along the vertical direction of the indicator rod 200 during the boiler expansion process. The indicator rod 200 moves on the scale plate 300 to make the indicator rod 200 move in different directions for measuring the expansion degree of the boiler.

[0021] like Figure 4 and Figure 5As shown, the first displacement sensor 400 is installed at the middle position between the indicator rod 200 and the sliding sleeve. The first displacement sensor 400 is a linear displacement sensor, so that the linear displacement sensor senses the vertical displacement of the indicator rod 200 through the linear variable differential transformer, and then measures and records the vertical displacement data of the indicator rod 200.

[0022] like Figure 4 and Figure 5 As shown, the second displacement sensor 500 includes a probe 510 and a sensing plate 520. The probe 510 is installed at the bottom of the indicator rod 200, and the sensing plate 520 is installed at the bottom of the scale plate 300. The sensing plate 520 is a resistive sensing plate 520, so that the probe 510 is displaced along the scale plate 300, so that the sensing plate 520 and the probe form a sliding rheostat. The change in resistance is converted into a displacement signal, thereby sensing the displacement data of the probe 510 at the bottom of the indicator rod 200. The displacement data of the horizontal position of the indicator rod 200 is then transmitted to the microcontroller in a timely manner through the second connecting line 1000 installed at the third connecting port on the side of the scale plate 300.

[0023] like Figure 4 and Figure 5 As shown, antenna 600 is snapped onto the first connection port on the right side of fixed box 100. Fixed box 100 is equipped with an Internet of Things (IoT) module, and antenna 600 supports the LoRaWAN protocol. Antenna 600 is equipped with a transmitter inside, so that antenna 600 can transmit boiler expansion data to the monitoring system in a timely manner through the IoT network, avoiding manual patrol and recording, which is inefficient and cannot detect expansion overload in a timely manner.

[0024] like Figure 4 and Figure 5 As shown, the buzzer 700 and warning light 800 are mounted side-by-side on the top of the fixed box 100 and connected to the microcontroller via wires. The microcontroller compares the displacement data with a preset threshold. If the limit is exceeded, the buzzer 700 is triggered, so that the buzzer 700 and warning light 800 can promptly sound an alarm and flash a light to warn of boiler expansion exceeding the range, based on the data output by the microcontroller. This allows patrol personnel to quickly locate the expansion position, address the boiler overload, and monitor and warn of boiler expansion data in a timely manner, thereby improving the safety of boiler operation.

[0025] like Figure 3 As shown, a battery compartment is provided at the bottom of the fixed box 100, and a battery is installed in the battery compartment so that the battery can provide power to the sensing element on the sensor so that the sensing element can operate normally.

[0026] like Figure 2 and Figure 4As shown, the rear end of the fixed box 100 is provided with several first connection ports. The first connection ports are arranged side by side and spaced apart along the horizontal direction. The two first connection ports on the left are connected to corresponding first connection lines 900 and second connection lines 1000. The other end of the first connection line 900 is connected to the second connection port on the top of the indicator rod 200, and the other end of the second connection line 1000 is connected to the third connection port on the side of the scale plate 300. This allows the expansion data sensed by the first displacement sensor 400 and the second displacement sensor 500 to be transmitted to the microcontroller in a timely manner through the connection lines connected to each connection port. This enables the microcontroller to analyze and process the acquired data in a timely manner, obtain the expansion data during the boiler combustion process, and view it in real time, improving the convenience of expansion data acquisition. At the same time, it allows for timely adjustment of the boiler combustion data according to the boiler's expansion degree, thereby improving the boiler's operational safety.

[0027] like Figure 1 and Figure 2 As shown, the scale plate 300 is installed on the base plate 310, and a support frame 320 is installed at the bottom of the base plate 310 to support the base plate 310. The support frame 320 has a triangular structure so that the strength of the support frame 320 can stably support the base plate 310 and prevent the scale plate 300 from shifting during use, thereby affecting the acquisition of boiler expansion data.

[0028] The working principle of an integrated boiler expansion IoT sensor of this utility model: In thermal power generation, coal is burned in a boiler to convert heat energy into electrical energy. During combustion, the boiler expands due to heat. Existing boiler expansion data is collected using mechanical expansion indicators on the boiler's outer wall. However, these mechanical indicators cannot fully reflect the expansion of all heated surfaces. Furthermore, during boiler startup, manual inspections at various monitoring points are required, which is labor-intensive and lacks real-time data accuracy. After the boiler is running normally, manual inspections involve climbing up and down stairs, and are affected by factors such as lighting conditions at night and personnel condition, making the process cumbersome and unsafe. Data recording uses paper-and-pen reports, which cannot intuitively and in real-time display boiler expansion changes, nor can they provide early warnings of excessive boiler expansion. By installing a first displacement sensor 400 and a second displacement sensor 500 at the middle and bottom of the indicator rod 200 of a traditional mechanical expansion indicator, the vertical and horizontal displacements of the boiler detected by the indicator rod 200 are dynamically sensed and recorded. This data is then transmitted to a microcontroller via a first connecting line 900 and a second connecting line 1000. After data integration on the microcontroller, the expansion data is read and sent to the software system via an Internet of Things (IoT) network. The expansion data is also integrated into a boiler 3D visualization system, where specialized graphics software is used to display and store the expansion data. Expansion data can now be viewed in the office, collected and displayed in real time, completely solving the problem of needing to manually record boiler expansion data periodically. By setting up dual sensors, the measurement error has been reduced from the original 2mm to 0.5mm. At the same time, a buzzer 700 and a warning light 800 are installed on the top of the fixed box 100. The buzzer 700 and the warning light 800 can promptly sound an alarm and flash a light when the boiler expansion exceeds the range, based on the data output by the microcontroller. This makes it easier for patrol personnel to quickly find the expansion location, handle the boiler overload, and monitor and warn of boiler expansion data in a timely manner, thereby improving the safety of boiler operation.

[0029] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
