[0047] The following combination Figures 1 to 7 A specific embodiment of the gas pipeline monitoring device of the present invention is described.

[0048] The gas pipeline monitoring device of an embodiment of the present invention includes a power supply mechanism, a detection mechanism and a signal transmission mechanism, wherein the power supply mechanism is used to supply power to the detection mechanism and the signal transmission mechanism, the detection mechanism is used to detect the gas pipeline 1, and the signal transmission mechanism is used to transmit the detection data collected by the detection mechanism to a remote terminal in real time.

[0049] The power supply mechanism is installed inside the gas pipeline 1. A mounting notch is provided at the top of the gas pipeline 1, where a sealing block 2 is removably mounted. The power supply mechanism comprises a support column 3, multiple wind turbine generators mounted on the support column 3, and multiple battery packs 4 corresponding to each wind turbine generator. The top of the support column 3 is fixedly connected to the sealing block 2, while the bottom of the support column 3 is fixedly connected to the bottom of the gas pipeline 1. Each wind turbine generator is electrically connected to a corresponding battery pack 4. In other words, the support column 3 is perpendicular to the axial direction of the gas pipeline 1, thereby supporting the power supply mechanism and installing it inside the gas pipeline 1.

[0050] Among them, the detection mechanism is arranged inside the gas pipeline 1. The detection mechanism includes a detection tube group 5, a communication cable 6 installed inside the detection tube group 5, and a plurality of gas pressure sensors 7 installed on the detection tube group 5. The detection tube group 5 is arranged on the inner side wall of the bottom of the gas pipeline 1. One end of the detection tube group 5 is connected to the bottom of the support column 3, and the other end of the detection tube group 5 is extended along the length direction of the gas pipeline 1. The plurality of gas pressure sensors 7 are respectively arranged in sequence along the length direction of the detection tube group 5. Each gas pressure sensor 7 is electrically connected to the communication cable 6, and the communication cable 6 is electrically connected to the battery pack 4. Among them, each gas pressure sensor 7 is arranged in parallel. That is, the arrangement of the detection tube group 5 and the plurality of gas pressure sensors 7 is convenient, which can ensure that the gas pipeline 1 is effectively monitored as a whole in the length direction of the gas pipeline 1, and the detection data of each gas pressure sensor 7 can be used to promptly determine the specific location of the problem in the gas pipeline 1.

[0051] The signal transmission mechanism is disposed outside the gas pipeline 1 and mounted on the sealing block 2. The signal transmission mechanism is electrically connected to the communication cable 6 and is used for wireless connection with the remote terminal. The signal transmission mechanism can transmit the detection data of each gas pressure sensor 7 to the remote terminal in real time.

[0052] The gas pipeline monitoring device of the embodiment of the present invention only needs to open an installation notch at the top of the gas pipeline 1 during installation, and then install the power supply mechanism and the detection mechanism inside the gas pipeline 1 respectively, and install the signal transmission mechanism on the sealing block 2, and then install the sealing block 2 at the installation notch, so that the monitoring device can be installed and fixed on the gas pipeline 1, thereby eliminating the need for complicated installation processes and large-scale cutting and installation of the entire gas pipeline 1. It can better match various new and old gas pipelines 1, making installation more convenient, effectively reducing the difficulty of installation, and improving installation efficiency.

[0053] The gas pipeline monitoring device of the embodiment of the present invention is configured such that, when in use, each wind turbine generator mechanism can utilize the gas flowing in the gas pipeline 1 to generate electricity and store the electrical energy in the corresponding battery packs 4. The battery packs 4 then provide working power to each gas pressure sensor 7. The gas pipeline 1 as a whole can be accurately monitored in real time through each gas pressure sensor 7. Each gas pressure sensor 7 can transmit detection data to a signal transmission mechanism in real time via a communication cable 6, and then the collected detection data can be transmitted to a remote terminal in real time via the signal transmission mechanism. Therefore, when an accident occurs (such as a field pipeline rupture or valve leakage), the location of the accident can be quickly determined, and the location of the problem in the gas pipeline 1 can be directly narrowed down to a predetermined range through the detection data fed back by each gas pressure sensor 7. This not only improves the monitoring accuracy, but also facilitates rapid maintenance and reduces the overall blocking time of the gas pipeline 1.

[0054] During monitoring, the gas pressure sensors 7 may be numbered and divided into two groups as shown in Table 1 below:

[0055]

[0056] Table 1

[0057] As can be seen from Table 1, a significant pressure drop occurs at the 00-03~00-04 position of Group 1 and the 00-04~00-05 position of Group 2. This indicates that there may be obvious leakage or other problems at these positions. Therefore, the problem position of the gas pipeline 1 can be quickly and accurately determined and repaired.

[0058] Specifically, if Figure 7 As shown, the wind turbine generator utilizes the kinetic energy of the gas in the gas pipeline 1 to generate electricity. When the battery pack 4 has sufficient power, it preferentially powers the gas pressure sensors 7. When the battery pack 4 has insufficient power, an external power source can also be used to power the battery pack 4 and the gas pressure sensors 7.

[0059] Specifically, each wind turbine generator system includes an impeller and a generator rotor group coaxially connected to the impeller. The flowing gas in the gas pipeline 1 can drive the impeller to rotate, and the rotation of the impeller can drive the generator rotor group to rotate, thereby generating electrical energy through the generator rotor group. The generated electrical energy will be stored in the corresponding battery group 4.

[0060] Specifically, the power supply mechanism also includes a duct shell 11 covering the periphery of each impeller. The duct shell 11 can form an air guide channel for guiding the flow of gas around each impeller, thereby increasing the air flow speed and improving the power generation efficiency of each wind wheel power generation mechanism.

[0061] The duct housing 11 can be either a one-piece or split structure. In the one-piece structure, the upper end of the duct housing 11 is connected to the upper portion of the support column 3, and the lower end of the duct housing 11 is connected to the lower portion of the support column 3, thereby achieving secure installation of the duct housing 11 on the support column 3. In the split structure, the duct housing 11 includes an upper duct housing and a lower duct housing. The upper duct housing is connected to the upper portion of the support column 3, and the lower duct housing is connected to the lower portion of the support column 3, thereby achieving secure installation of the duct housing 11 on the support column 3.

[0062] Specifically, the number of wind turbine generators and the corresponding number of battery packs 4 can be set according to actual use requirements. The following is a specific description using an example in which the power supply mechanism includes three wind turbine generators and corresponding three battery packs 4.

[0063] In a specific embodiment of the present invention, the support string 3 includes a first string section 301, a second string section 302, a third string section 303, and a fourth string section 304, which are spaced apart from each other from top to bottom.

The first generating rotor group is installed in the installation chamber of the first tubular section 301 through the first rotating shaft 802, the second generating rotor group is installed in the installation chamber of the third tubular section 303 through the second rotating shaft, and the third generating rotor group 102 is installed in the installation chamber of the fourth tubular section 304 through the third rotating shaft 103.

[0065] The power supply mechanism includes three battery packs 4: a first battery pack, a second battery pack, and a third battery pack. The first battery pack is installed in the mounting chamber of the first tubular section 301 and is electrically connected to the first generator rotor assembly. The second battery pack is installed in the mounting chamber of the third tubular section 303 and is electrically connected to the second generator rotor assembly. The third battery pack is installed in the mounting chamber of the fourth tubular section 304 and is electrically connected to the third generator rotor assembly 102.

[0066] In some embodiments of the present invention, the first impeller 801 includes a first mounting ring 801A, a plurality of first rotating blades 801B arranged on the outer side wall of the first mounting ring 801A, and a plurality of first clamping plates 801C arranged on the inner side wall of the first mounting ring 801A. A plurality of first clamping grooves 802A matching the first clamping plates 801C are provided on the first rotating shaft 802, and each first clamping plate 801C is correspondingly clamped in each first clamping groove 802A so that the first mounting ring 801A is fixed on the first rotating shaft 802.

[0067] Correspondingly, the second impeller 901 includes a second mounting ring, a plurality of second rotating blades arranged on the outer side wall of the second mounting ring, and a plurality of second clamping plates arranged on the inner side wall of the second mounting ring. A plurality of second clamping grooves adapted to the second clamping plates are provided on the second rotating shaft, and each second clamping plate is correspondingly clamped in each second clamping groove so that the second mounting ring is fixed on the second rotating shaft.

[0069] In some embodiments of the present invention, the detection tube group 5 includes a first branch section 501 and a second branch section 502, which are connected by a plurality of connecting lines 503. The plurality of connecting lines 503 are arranged in a ring shape between the end face of the first branch section 501 and the end face of the second branch section 502, so that the plurality of connecting lines 503 enclose an installation channel for the communication cable 6 to pass through.

That is, by providing the first branch section 501, the influence of the vibration of the impeller rotating on the gas pressure sensors 7 on the second branch section 502 can be reduced, so that the vibration is not transmitted in an orderly manner. The connecting line 503 is made of twisted steel wire. The function of the connecting line 503 is to connect the first branch section 501 and the second branch section 502. After the connection, the vibration cannot be directly transmitted to the second branch section 502 along the first branch section 501 in an orderly manner, thereby further reducing the impact force on the gas pressure sensor 7.
