Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline monitoring technology, and in particular to an Internet of Things pressure monitoring device. Background Technology

[0002] Long-distance gas pipelines are common in industrial settings such as petrochemicals and gas transmission. These pipelines connect large-scale natural gas fields or manufactured gas with areas where gas is consumed. The ends of the main and branch pipelines connect to towns or large industrial enterprises, serving as the gas source for the supply area. Some pipelines are erected in the air, while others are buried underground.

[0003] Compared to other pipelines, gas pipelines have particularly strict requirements because gas leaks can lead to accidents such as fires, explosions, and poisoning. The higher the pressure in the gas pipeline, the greater the possibility of pipe joints coming loose and cracks appearing in the pipeline itself. Therefore, pressure monitoring of gas pipelines is a key link in ensuring safe operation. When testing the pressure of gas pipelines, workers usually need to use handheld detectors to check along the pipeline to determine if there is a leak. This method is inefficient, especially for pipelines buried deep underground, where testing is even more cumbersome and inefficient. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] This embodiment provides an Internet of Things (IoT) pressure monitoring device that can remotely monitor the pressure value of gas pipelines in real time, thereby improving detection efficiency.

[0031] Please see Figure 1 The IoT pressure monitoring device includes a pressure measuring tube 1, a pressure transmitter 2, and an explosion-proof box 3. One end of the pressure measuring tube 1 is connected to the gas supply pipe 10, and the other end is connected to the pressure transmitter 2. The pressure transmitter 2 is used to detect the pressure information of the gas supply pipe 10 and convert it into an electrical signal. The explosion-proof box 3 is installed remotely to remotely receive and convert the electrical signal of the pressure transmitter 2 and display it as a readable pressure value for the staff to read intuitively.

[0032] Preferably, the pressure measuring tube 1 is a capillary tube. The capillary tube has a certain degree of flexibility and can absorb some of the vibration energy when subjected to vibration, thereby reducing the direct impact on the pressure transmitter 2 and avoiding unstable readings of the pressure transmitter 2.

[0033] More preferably, the pressure measuring tube 1 is filled with a filling fluid to isolate the pressure transmitter 2 from the natural gas in the gas transmission pipe 10, preventing damage caused by direct contact between the pressure transmitter 2 and the natural gas. For example, silicone oil is used as the filling fluid.

[0034] Alternatively, please continue reading Figure 1The IoT pressure monitoring device also includes an instrument valve 7, which is installed on the pressure measuring pipe 1. The instrument valve 7 is used to connect or disconnect the natural gas in the pressure measuring pipe 1 to start or stop pressure monitoring of the transmission pipe. By setting the instrument valve 7, after the pressure transmitter 2 has been used for a long time, the pressure measuring pipe 1 can be disconnected through the instrument valve 7, allowing for direct maintenance and disassembly of the pressure transmitter 2. Preferably, the instrument valve 7 is a shut-off valve.

[0035] For example, the pressure transmitter 2 includes a body, a sensor, and a connector. The connector is installed at the lower end of the body, the sensor is disposed inside the connector, and the connector is sealed to the other end of the pressure measuring tube 1. The sensor is used to detect the pressure information of the gas supply tube 10 and convert it into an electrical signal.

[0036] Specifically, please refer to Figure 1 and Figure 2 The explosion-proof box 3 includes a housing 31 and a digital display 33. The digital display 33 is mounted on the surface of the housing 31. The digital display 33 is connected to a sensor to receive and convert the electrical signal of the sensor and display it as a readable pressure value so that the staff can read it intuitively.

[0037] Alternatively, the housing 31 may be made of aluminum alloy or stainless steel, which is corrosion resistant and has high strength.

[0038] Furthermore, the digital display 33 provided in this embodiment is connected to an external mains power supply.

[0039] Furthermore, to ensure power supply stability, please refer to [link / reference needed]. Figure 2 The explosion-proof box 3 provided in this embodiment also includes a storage battery 32, which is installed inside the housing 31 and is electrically connected to the digital display 33 to supply power to the digital display 33 in the event of a power outage.

[0040] For example, the battery 32 is equipped with a power switch. In the event of a mains power outage, the power switch enables the battery 32 to supply power to the digital display 33, thereby ensuring the stability of the power supply.

[0041] Please see Figure 1 The IoT pressure monitoring device provided in this embodiment is also equipped with a photovoltaic panel 4. The photovoltaic panel 4 is installed in a location with sufficient sunlight. The output interface of the photovoltaic panel 4 is connected to the electrical interface of the battery 32. The photovoltaic panel 4 converts solar energy into electrical energy and further stores the electrical energy in the battery 32.

[0042] It should be noted that in this embodiment, the pressure transmitter 2 is also equipped with a battery 32 for power supply, and the photovoltaic panel 4 is connected to the electrical interfaces of the two batteries 32 through two output interfaces respectively. The electrical energy converted by the photovoltaic panel 4 is stored in the two batteries 32 respectively.

[0043] This embodiment also includes a receiving and transmitting device, which enables data transmission between the digital display 33 and the sensor.

[0044] For example, the receiving and transmitting device includes a wired cable 51, through which the sensor and the digital display 33 are connected. The wired cable 51 transmits the electrical signal converted by the sensor to the digital display 33, and the digital display 33 performs further conversion.

[0045] For example, the receiving and transmitting device includes a wireless transmitting antenna 61 and a wireless receiving antenna 62 connected for communication. The wireless transmitting antenna 61 is connected to a sensor, and the wireless receiving antenna 62 is connected to a digital display 33. The wireless transmitting antenna 61 is used to transmit the electrical signal converted by the sensor, and the wireless receiving antenna 62 is used to receive the electrical signal transmitted by the wireless transmitting antenna 61 and transmit it to the digital display 33 for further conversion.

[0046] The IoT pressure monitoring device provided in this embodiment also has an early warning function, which issues an early warning to staff when the pressure value is abnormal, thereby improving the safety factor.

[0047] For example, the explosion-proof box 3 is also equipped with a control board and an early warning module. The receiving and transmitting device is connected to the control board, and the control board is connected to the digital display 33 and the early warning module. On the one hand, the control board can receive the electrical signals transmitted by the receiving and transmitting device and transmit them to the digital display 33. On the other hand, in the case of abnormal electrical signals, the control board can also activate the early warning module to issue an alarm.

[0048] It should be noted that when the receiving and transmitting device includes a wired cable 51, the wired cable 51 connects the sensor and the control board; when the receiving and transmitting device includes a wireless transmitting antenna 61 and a wireless receiving antenna 62 for communication connection, the wireless receiving antenna 62 connects to the control board.

[0049] Optionally, the warning module includes a buzzer connected to the control board, which can control the buzzer to sound an alarm.

[0050] Furthermore, the digital display 33 can also transmit the electrical signals from the sensor to an external device, which can then record and process the pressure data of the delivery pipe being monitored.

[0051] For example, the explosion-proof box 3 is also equipped with an Internet of Things (IoT) module 34. The IoT module 34 connects the sensor to the external device. The IoT module 34 is wirelessly connected to the external device. The IoT module 34 receives the electrical signals from the sensor and wirelessly transmits them to the external device.

[0052] The IoT pressure monitoring device provided in this embodiment has the following beneficial effects:

[0053] The pressure data is displayed intuitively by the digital display instrument 33 installed on the explosion-proof box 3, which enables remote real-time monitoring of the pressure value of the gas pipeline 10, thereby improving the detection efficiency.

[0054] By filling the pressure measuring tube 1 with filling liquid, the pressure transmitter 2 is isolated from the natural gas in the gas transmission pipe 10, preventing the pressure transmitter 2 from being damaged by direct contact with natural gas.

[0055] By installing instrument valve 7 on pressure measuring tube 1, it is convenient to directly maintain and disassemble pressure transmitter 2;

[0056] By setting up battery 32, the stability of power supply is improved;

[0057] By installing a control board and an early warning module in the explosion-proof box 3, timely early warning can be given in case of abnormal pressure in the gas pipeline 10.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
