[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 The gas pipeline monitoring system includes two semi-circular arc-shaped plates 1, which are connected by bolts. Anti-slip pads, which are rubber pads, are fixedly installed on the inner side of each arc-shaped plate 1. When installing the two arc-shaped plates 1, they are placed on the gas pipeline and can be spliced ​​together to form a circle. Then, the two arc-shaped plates 1 are connected together by bolts. The anti-slip pads can increase the friction between the gas pipeline and the arc-shaped plates 1, preventing the arc-shaped plates 1 from rotating on the gas pipeline.

[0024] Both arc-shaped plates 1 are provided with arc-shaped grooves 2. Slider 3 is slidably mounted on the two arc-shaped plates 1 through a sliding assembly. An L-shaped bracket 4 is fixedly mounted on the slider 3. A laser leak detector 5 is mounted on the bracket 4 through an installation assembly. Arc-shaped limiting grooves 9 are provided on the inner walls of both sides of the arc-shaped groove 2. The sliding assembly includes two sliding blocks 10 that are slidably mounted in the two limiting grooves 9 respectively. Both sliding blocks 10 are fixedly connected to the slider 3. The slider 3 is slidably positioned in the arc-shaped groove 2. When the two arc-shaped plates 1 are joined together, the arc-shaped grooves 2 and limiting grooves 9 on the two arc-shaped plates 1 will also be joined together. The sliding blocks 10 can slide in the limiting grooves 9, thereby ensuring that the slider 3 can slide in the arc-shaped groove 2. When the slider 3 slides in the arc-shaped groove 2, it can drive the laser leak detector 5 to slide in a ring on the surface of the gas pipeline.

[0025] A semi-circular arc gear ring 6 is fixedly installed on each of the two arc plates 1. A drive motor 7 is fixedly installed on the slider 3. A spur gear 8 is fixedly installed on one end of the output shaft of the drive motor 7. The spur gear 8 meshes with the arc gear ring 6.

[0026] When the two arc-shaped plates 1 are joined together, the two arc-shaped gear rings 6 can be joined into a circle. When monitoring the gas, the drive motor 7 is started, which drives the spur gear 8 to rotate. Since the spur gear 8 is meshed with the arc-shaped gear ring 6, the spur gear 8 will roll on the arc-shaped gear ring 6, and at the same time drive the slider 3 to slide in the arc-shaped groove 2. During the sliding process, the slider 3 will drive the laser leak detector 5 to slide in a ring along the arc-shaped groove 2 on the gas pipeline, so that the emitted laser can rotate around the surface of the gas pipeline, thereby increasing the monitoring range of the laser leak detector 5 and improving the monitoring effect of the laser leak detector 5.

[0027] The mounting assembly includes a rotating shaft 11 rotatably mounted on a bracket 4 and a mounting plate 12 fixedly mounted on the upper end of the rotating shaft 11. The laser leak detector 5 is fixedly mounted on the mounting plate 12. The slider 3 is provided with a transmission assembly for driving the rotating shaft 11 to rotate. The transmission assembly includes a first bevel gear 13 fixedly mounted on the lower end of the rotating shaft 11 and a second bevel gear 14 fixedly sleeved on the output shaft of the drive motor 7. The first bevel gear 13 and the second bevel gear 14 are meshed together. When the drive motor 7 drives the spur gear 8 to rotate, it also drives the second bevel gear 14 to rotate. Then, the first bevel gear 13 drives the rotating shaft 11 to rotate on the bracket 4, which in turn drives the laser leak detector 5 to rotate through the mounting plate 12. This allows the laser leak detector 5 to rotate around the surface of the gas pipeline while also rotating around itself, thereby further increasing the monitoring range of the laser leak detector 5 and improving its monitoring effect.

[0028] The alarm safety device includes an alarm 15, which is fixedly installed on the mounting plate 12. The alarm 15 contains a control chip, which is electrically connected to the laser leak detector 5. When the laser leak detector 5 detects a gas leak, it will trigger the alarm 15 through the control chip to issue an alarm prompt. At the same time, it will wirelessly transmit the monitored data to the control room, further improving the safety of the device.

[0029] In this invention, when two arc-shaped plates 1 are joined together, two arc-shaped gear rings 6 can be joined into a circle. When monitoring the gas, the drive motor 7 is started, which drives the spur gear 8 to rotate. Since the spur gear 8 is meshed with the arc-shaped gear ring 6, the spur gear 8 will roll on the arc-shaped gear ring 6, and at the same time drive the slider 3 to slide in the arc-shaped groove 2. During the sliding process, the slider 3 will drive the laser leak detector 5 to slide in a ring along the arc-shaped groove 2 on the gas pipeline, so that the emitted laser can rotate around the surface of the gas pipeline, thereby increasing the monitoring range of the laser leak detector 5 and improving the monitoring effect of the laser leak detector 5.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
