Description

Technical Field

[0001] This utility model relates to the field of gas flow detection technology, specifically a gas flow anomaly detection terminal. Background Technology

[0002] Gas fuels are a general term for gaseous fuels that can burn and release heat for use by urban residents and industrial enterprises. Gas fuels include manufactured gas (commonly known as coal gas), liquefied petroleum gas (LPG), and natural gas. In the 21st century, the urban population using gas has maintained a rapid growth trend, and correspondingly, the penetration rate of China's gas industry has also increased rapidly.

[0003] Gas needs to be monitored during actual use to prevent leaks that could threaten lives and property. Existing gas flow anomaly detection terminals generally use smart gas flow meters. However, the length of these smart gas flow meters is not adjustable, and they need to be connected to two gas pipelines. It is difficult to control the distance between the two gas pipelines to perfectly match the smart gas flow meter. This requires multiple careful cutting and adjustment of the gas pipelines to ensure a proper fit, which makes the connection between the smart gas flow meter and the gas pipelines very inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gas flow anomaly detection terminal, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas flow abnormality detection terminal, including a gas flow meter, wherein the gas flow meter is provided with two connecting mechanisms, each connecting mechanism including a movable connecting cylinder, the outer side wall of the movable connecting cylinder is provided with an annular opening, and the opposite sides of the two annular openings are provided with an annular movable groove, the annular movable groove is provided with a compression ring inside, and multiple connecting rods are slidably connected inside the movable connecting cylinder; Both of the two movable connecting cylinders have annular rings on opposite sides. The end of the connecting rod away from the extrusion ring is fixedly connected to the annular ring. An annular sealing rubber ring is provided inside the annular opening. An annular extrusion groove is provided on the side of the annular sealing rubber ring near the extrusion ring. A flange connection mechanism is integrally formed on the side of the movable connecting cylinder away from the gas flow meter. Annular grooves are provided on opposite sides of both movable connecting cylinders.

[0006] Preferably, a plurality of tension springs are fixed to the right side of the compression ring, and the other end of the tension springs is fixedly connected to the annular movable groove.

[0007] Preferably, the movable connecting cylinder, the ring, and the connecting rod are all made of stainless steel.

[0009] Preferably, a battery is fixed on the rear surface of the motherboard below the processing module.

[0010] Preferably, a charging port is fixed on the rear surface of the motherboard on the left side of the processing module. Beneficial effects

[0011] This utility model provides a gas flow anomaly detection terminal. Compared with the prior art, it has the following advantages: This gas flow anomaly detection terminal, through a connecting mechanism, positions the device before two gas pipelines. This allows the movable connecting cylinder to be pulled according to the distance between the two gas pipelines, bringing it into contact with the pipelines and securing them together. The pipeline then compresses a ring, which pushes the connecting rod and the compression ring to move. The compression ring inserts into an annular compression groove, compressing a sealing rubber ring. The sealing rubber ring compresses both outwards and inwards; the inner side compresses the inner wall of the annular opening, while the outer side compresses the inner wall of the gas flow meter pipeline, thus sealing and preventing gas leakage. This design facilitates connection between the device and the gas pipelines when the distance between the two gas pipelines is greater than the length of the gas flow meter.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a gas flow abnormality detection terminal, including a gas flow meter 2. The gas flow meter 2 has two connecting mechanisms 1 inside. Each connecting mechanism 1 includes a movable connecting cylinder 104. An annular opening 107 is formed on the outer wall of the movable connecting cylinder 104. An annular movable groove 108 is formed on the opposite sides of the two annular openings 107. A compression ring 101 is provided inside the annular movable groove 108. Multiple connecting rods 102 are slidably connected inside the movable connecting cylinder 104. A circular ring 103 is provided on the opposite sides of the two movable connecting cylinders 104. The end of each connecting rod 102 away from the compression ring 101 is fixedly connected to the circular ring 103. An annular sealing rubber ring 106 is provided inside the annular opening 107. The annular sealing rubber ring 106 has an annular extrusion groove 110 on the side near the extrusion ring 101. The movable connecting cylinder 104 has an integrally formed flange connection mechanism 111 on the side away from the gas flow meter 2. Both movable connecting cylinders 104 have annular grooves 109 on opposite sides to facilitate the connection between the device and the gas pipeline. Multiple tension springs 105 are fixed on the right side of the extrusion ring 101. The other end of the tension spring 105 is fixedly connected to the annular movable groove 108. When the movable connecting cylinder 104 and the gas pipeline are released, the tension spring 105 can pull the extrusion ring 101 away from the annular extrusion groove 110. The movable connecting cylinder 104, the ring 103 and the connecting rod 102 are all made of stainless steel to prevent rusting.

[0020] Furthermore, a housing 3 is fixed to the rear surface of the gas flow meter 2. A main board 7 is fixed inside the housing 3. A processing module 6 is fixed to the rear surface of the main board 7. A signal transmitting antenna 4 is fixed inside the housing 3. The signal transmitting antenna 4 and the main board 7 are fixedly connected, so that the monitored gas flow can be sent to the customer's mobile phone for the customer to view and understand. A battery 5 is fixed to the rear surface of the main board 7 below the processing module 6, so that it can provide power and allow the device to work in the event of a power outage. A charging port 8 is fixed to the left side of the processing module 6 on the rear surface of the main board 7, so that the battery 5 can be charged.

[0021] During operation, the device is positioned in front of two gas pipelines. The movable connecting cylinder 104 is then pulled according to the distance between the two gas pipelines, bringing it into contact with the pipelines and securing it tightly. This causes the pipeline to compress the annular ring 103, which in turn pushes the connecting rod 102 and the compression ring 101. The compression ring 101 inserts into the annular compression groove 110, compressing the sealing rubber ring 106. The sealing rubber ring 106 compresses outwards and inwards, with the inner side compressing the inner wall of the annular opening 107 and the outer side compressing the inner wall of the gas flow meter 2 pipeline, thus sealing against gas leakage. When the distance between the two gas pipelines is greater than the length of the gas flow meter 2, it facilitates connection between the device and the gas pipelines. After connection, the gas flow meter 2 continuously monitors the gas flow rate, and the signal transmitting antenna 4 sends the gas flow rate data to the customer's mobile phone, allowing the customer to view the gas flow status in real time and prevent gas leakage.
