The probe 1212 is used to collect temperature information. The control mechanism 124 is disposed inside the chamber 111. The housing 110 provides protection for the control mechanism 124.

[0028] Optionally, the dynamic pressure pipe 122 includes a total pressure acquisition port 1221, which is positioned facing the flue gas during the operation of the temperature, pressure and flow detection device 100 to acquire total pressure information within the chimney. The static pressure pipe 123 includes a static pressure acquisition port 1231, which is positioned away from the flue gas during the operation of the temperature, pressure and flow detection device 100 to acquire static pressure information within the chimney. The control mechanism 124 includes a differential pressure transmitter, which is connected to the dynamic pressure pipe 122 and the static pressure pipe 123 and obtains differential pressure information based on the total pressure information and static pressure information. The temperature, pressure and flow detection device 100 also includes a processor, which can obtain flow rate information based on the differential pressure information, total pressure information, static pressure information, and temperature information.

[0029] Optionally, the temperature measuring mechanism 121 includes an extension 1211 and a probe 1212. The probe 1212 extends out of the chamber 111 to collect temperature information inside the chimney. The control mechanism 124 includes a temperature transmitter. The extension 1211 is connected to the temperature transmitter. The temperature information collected by the probe 1212 is transmitted to the temperature transmitter through the extension 1211. The temperature transmitter converts the temperature information into an electrical signal and transmits it to the processor.

[0030] Optionally, the first pipeline 131 and the housing 110 are connected to enhance the stability of the first pipeline 131. The connection method can be clamp fixing, bonding, welding or threaded connection, etc.

[0031] Optionally, the first conduit 131 and the probe part 1212 are spaced apart to avoid the probe part 1212 or the surface of the probe part 1212 from clogging the purge port 134. The specific spacing value between the first conduit 131 and the probe part 1212 can be determined by the user.

[0032] Optionally, the probe portion 1212 is cylindrical, and the dynamic pressure tube 122 and the static pressure tube 123 are respectively disposed on both sides of the probe portion 1212 along the radial direction of the probe portion 1212. Along the radial direction of the probe portion 1212, the first pipe 131 is located on the side of the static pressure tube 123 away from the probe portion 1212. The fan-shaped airflow formed by the purge port 134 can blow away the dust on the surface of the probe portion 1212 and reduce the risk of the blown dust entering the static pressure collection hole 1231 and clogging the static pressure tube 123.

[0033] Optionally, the dynamic pressure tube 122 and the static pressure tube 123 are respectively arranged at intervals on both sides of the probe part 1212 in the second direction, and the first pipe 131 is located on one side of the probe part 1212 in the third direction. The first direction X, the second direction and the third direction intersect each other, and the fan-shaped airflow formed by the blow port 134 can directly blow away the dust on the surface of the probe part 1212.

[0034] Optionally, the probe part 1212 is located on the side of the static pressure tube 123 away from the dynamic pressure tube 122. The probe part 1212 is located between the static pressure tube 123 and the first pipeline 131. The fan-shaped airflow formed by the blow port 134 can directly blow away the dust on the surface of the probe part 1212.

[0035] Optionally, the first conduit 131 may be provided with one or more purge ports 134. For example, the first conduit 131 may be provided with 1, 2, 3, or 10 purge ports 134.

[0036] Specifically, during the operation of the temperature, pressure, and flow detection device 100, the probe 1212 is located inside the chimney. Dust and impurities inside the chimney gradually accumulate on the outer surface of the probe 1212. The dust accumulated on the outer surface of the probe 1212 has a heat-insulating effect, causing the temperature information measured by the probe 1212 to be lower than the actual temperature information. Therefore, in this embodiment, a first pipeline 131 is provided. After dust and impurities accumulate on the outer surface of the probe 1212, a gas medium can be output to the probe 1212 through the purge port 134 of the first pipeline 131 to purge the dust on the outer surface of the probe 1212.

[0037] Optionally, the input end of the first pipeline 131 can be connected to an external gas supply structure, which helps to enhance the flexibility of the temperature, pressure and flow detection device 100; or the cleaning assembly 130 may also include a storage structure 138 for storing a gaseous medium, with the first pipeline 131 and the storage structure 138 connected, and the gaseous medium being supplied to the first pipeline 131 through the storage structure 138, which helps to enhance the integration of the temperature, pressure and flow detection device 100.

In the closed state, the first valve 1351 blocks the first pipeline 131, and in the open state, the first valve 1351 opens the first pipeline 131.

[0041] In these embodiments, the first valve 1351 controls the opening and closing of the first pipeline 131 so that the first pipeline 131 can clean impurities on the surface of the probe part 1212, while also avoiding the situation where the probe part 1212 is inaccurate in temperature measurement due to the continuous blowing of the first pipeline 131 on the probe part 1212.

[0042] Optionally, the first valve 1351 is a solenoid valve, which reduces the control difficulty of the cleaning assembly 130.

[0043] Optionally, the first valve 1351 is connected to the processor. The first valve 1351 is configured to switch from a closed state to an open state after a first preset time, and the first pipeline 131 purges the probe section 1212, switching from an open state to a closed state after a second preset time. For example, the first preset time is 3 hours and the second preset time is 30 seconds.

[0045] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a temperature, pressure and flow detection device provided in another embodiment of this application.

[0046] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the cleaning assembly 130 also includes a second pipe 132 and a third pipe 133. The second pipe 132 is connected to the dynamic pressure pipe 122, and the third pipe 133 is connected to the static pressure pipe 123. The second pipe 132 and the third pipe 133 are respectively used to deliver gas medium to the dynamic pressure pipe 122 and the static pressure pipe 123. The second pipe 132 and the third pipe 133 are both connected in series with the first valve 1351. Alternatively, the cleaning assembly 130 also includes a second valve 1352 and a third valve 1353, which are respectively disposed in the second pipe 132 and the third pipe 133.

[0047] In these embodiments, the cleaning assembly 130 includes a second pipeline 132 and a third pipeline 133 for supplying gaseous media to the dynamic pressure pipeline 122 and the static pressure pipeline 123, respectively, to reduce the risk of blockage in the dynamic pressure pipeline 122 and the static pressure pipeline 123; both the second pipeline 132 and the third pipeline 133 are connected in series with the first valve 1351, which simultaneously controls the first pipeline 131, the second pipeline 132 and the third pipeline 133, thus simplifying the structure of the temperature, pressure and flow detection device 100; the cleaning assembly 130 also includes a second valve 1352 and a third valve 1353 respectively disposed in the second pipeline 132 and the third pipeline 133, which can be independently controlled, thus improving the accuracy and reliability of the cleaning assembly 130.

[0048] Optionally, the input end of the second pipe 132 can be connected to an external gas supply structure, which helps to enhance the flexibility of the temperature, pressure and flow detection device 100; or the cleaning assembly 130 may also include a storage structure 138 for storing gas medium, with both the first pipe 131 and the second pipe 132 connected to the storage structure 138, providing gas medium to the first pipe 131 and the second pipe 132 through the storage structure 138, which helps to enhance the integration of the temperature, pressure and flow detection device 100. The third pipe 133 is similar and will not be described in detail here.

[0049] Optionally, the second pipeline 132 and the third pipeline 133 are both connected in series with the first valve 1351. In the closed state, the first valve 1351 blocks the first pipeline 131, the second pipeline 132 and the third pipeline 133. In the open state, the first valve 1351 opens the first pipeline 131, the second pipeline 132 and the third pipeline 133.

[0050] Optionally, both the second valve 1352 and the third valve 1353 are solenoid valves.

[0051] Optionally, the second valve 1352 and the third valve 1353 are connected in series in the second pipeline 132 and the third pipeline 133, respectively, and the opening frequencies of the first valve 1351, the second valve 1352 and the third valve 1353 are the same or different.

[0052] In some embodiments, such as Figure 1 and Figure 3 As shown, the cleaning assembly 130 also includes a detection mechanism 136. The detection mechanism 136 is disposed in the housing 110 and faces the probe portion 1212. The detection mechanism 136 is used to collect information on the thickness of impurities on the outer surface of the probe portion 1212. The detection mechanism 136 is connected to a first valve 1351. The first valve 1351 is configured to switch from a closed state to an open state when the thickness of impurities on the outer surface of the probe portion 1212 exceeds a threshold.

[0053] In these embodiments, the cleaning assembly 130 also includes a detection mechanism 136, which is connected to the housing 110 to enhance its stability. The detection mechanism 136 is connected to a first valve 1351 so that the first valve 1351 can switch between a closed state and an open state based on the impurity thickness information on the outer surface of the probe portion 1212 collected by the detection mechanism 136, so that the cleaning assembly 130 can more accurately and reliably purge the probe portion 1212.

[0054] Optionally, the detection mechanism 136 can actively control the first valve 1351 to increase the purging frequency of the first pipeline 131 when the flue gas flow rate in the chimney increases, thereby enhancing the reliability of the cleaning assembly 130; and reduce the purging frequency of the first pipeline 131 when the flue gas flow rate in the chimney decreases, thereby reducing the overall energy consumption of the temperature, pressure and flow detection device 100.

[0055] For example, the detection mechanism 136 is a laser sensor, which detects the thickness of dust accumulated on the outer surface of the probe portion 1212.

[0056] Optionally, the testing mechanism 136 is fixed to the housing 110 by means of snap-fit, welding or bolt connection.

[0057] Optionally, the cleaning assembly 130 also includes a sealed cavity with a transparent window on its wall. The detection mechanism 136 is disposed in the sealed cavity and connected to the housing 110 through the sealed cavity. The detection mechanism 136 collects information on the thickness of impurities on the outer surface of the probe part 1212 through the transparent window. The sealed cavity reduces the impact of dust on the detection mechanism 136 and helps to extend the service life of the detection mechanism 136.

[0058] In some embodiments, such as Figure 1As shown, the first pipeline 131 includes a first section 1311 and a second section 1312 that are connected to each other. The first section 1311 is connected to the second section 1312 so that the gas medium can enter the second section 1312 from the first section 1311. The second section 1312 is connected to the housing 110, and the purge port 134 is provided in the second section 1312. The first section 1311 is flexibly deformable, and the rigidity of the second section 1312 is greater than that of the first section 1311.

[0059] In these embodiments, the first pipeline 131 includes a first segment 1311 and a second segment 1312 connected to each other. The rigidity of the second segment 1312 is greater than that of the first segment 1311. The second segment 1312 is connected to the housing 110, reducing the difficulty of fixing the first pipeline 131 and the housing 110. The purge port 134 is located on the rigid second segment 1312, which helps to improve the purge accuracy and stability of the purge port 134. The first segment 1311 is flexibly deformable and is connected to the second segment 1312 and the external air source, which reduces the difficulty of connecting the first pipeline 131 and the external air source and buffers the vibration of the second segment 1312 during operation, which helps to improve the service life of the temperature, pressure and flow detection device 100.

[0060] The first segment 1311 is connected to the second segment 1312, meaning that the inner cavities of the first segment 1311 and the second segment 1312 are connected. The gas medium can enter the second segment 1312 through the first segment 1311 and be blown to the probe part 1212 through the purge port 134 provided in the second segment 1312.

[0061] Optionally, the second segment 1312 is made of a metallic material to improve the structural strength of the second segment 1312.

[0062] Optionally, the second segment 1312 is fixedly connected to the housing 110, while the first segment 1311 and the second segment 1312 are detachably connected. During maintenance of the first pipeline 131, only the first segment 1311 and the second segment 1312 need to be disassembled, reducing the impact on the detection component 120. For example, the second segment 1312 is welded or bolted to the housing 110.

[0063] For example, the first segment 1311 can be a metal bellows, a high-pressure Teflon hose, etc.

[0064] In some embodiments, such as Figure 1 and Figure 4As shown, the second segment 1312 includes a connecting part 1371 and a blowing part 1372 that are connected to each other. The blowing part 1372 and the connecting part 1371 are connected and extend out of the housing 110 along the first direction X. The connecting part 1371 is connected to the housing 110 and is connected to the first segment 1311. A plurality of blowing ports 134 are provided on the blowing part 1372. The size of the blowing part 1372 in the first direction X is not less than the size of the probe part 1212 in the first direction X.

[0065] In these embodiments, the second segment 1312 includes a connecting portion 1371 and a purge portion 1372 that are interconnected. The connecting portion 1371 is connected to the housing 110 to enhance the stability of the second segment 1312. A plurality of purge ports 134 are disposed on the purge portion 1372. The dimension of the purge portion 1372 in the first direction X is not less than the dimension of the probe portion 1212 in the first direction X, so that the purge portion 1372 can provide sufficient purge effect for the probe portion 1212.

[0066] Optionally, multiple purge ports 134 are evenly spaced along the first direction X on the purge section 1372.

[0067] Optionally, the connecting part 1371 and the purging part 1372 are integrally formed to improve the sealing performance of the second section 1312 and reduce the risk of air leakage.

[0068] Optionally, the inner cavity of the purging section 1372 and the inner cavity of the connecting section 1371 are interconnected. The gas medium enters the purging section 1372 from the first segment 1311 through the connecting section 1371, and is purged to the probe section 1212 through the purging port 134 provided in the purging section 1372.

[0069] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a temperature, pressure and flow detection device provided in another embodiment of this application.

[0070] In some embodiments, such as Figure 1 and Figure 5 As shown, the second segment 1312 includes a plurality of purge sections 1372, which are spaced apart from each other and disposed on the outer periphery of the probe section 1212.

[0071] In these embodiments, the second segment 1312 includes a plurality of purge sections 1372 spaced apart from each other and disposed on the outer periphery of the probe section 1212. The plurality of purge sections 1372 can purge the probe section 1212 at multiple angles to reliably remove impurities from the outer surface of the probe section 1212.

[0072] Specifically, multiple purging sections 1372 are interconnected to simplify the structure of the first pipeline 131. For example, multiple purging sections 1372 are all connected to the same connecting section 1371.

[0073] Optionally, multiple purge sections 1372 are evenly spaced to facilitate uniform purging of the probe section 1212. For example, the number of purge sections 1372 can be 3, 4, 6, etc.

[0074] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a temperature, pressure and flow detection device provided in another embodiment of this application.

[0075] In some embodiments, such as Figure 1 and Figure 6 As shown, the purging part 1372 extends spirally in the first direction X and is disposed around the outer periphery of the probe part 1212.

[0076] In these embodiments, the purging part 1372 extends spirally in the first direction X and is disposed around the outer periphery of the probe part 1212 to provide a multi-angle purging effect to the probe part 1212 and improve purging efficiency.

[0077] Optionally, the purging part 1372 of the spiral device is arranged around the probe part 1212, the static pressure tube 123 and the dynamic pressure tube 122, so that while purging the probe part 1212, the static pressure tube 123 and the dynamic pressure tube 122 can also be purged.

[0078] Optionally, the cleaning assembly 130 also includes a support rod, one end of which is connected to the housing 110 and the other end of which is connected to the blowing part 1372 to fix and support the spiral blowing part 1372.
