Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas monitoring technology, and in particular to an online monitoring device for mixed gases. Background Technology
[0002] A mixed gas refers to a gas system in which two or more different gases are mixed in any proportion without undergoing a chemical reaction and coexist in the same container. In order to ensure the concentration and purity of the mixed gas, it is usually transported through pipelines, and a monitoring device resembling a pressure gauge is installed at the pipeline to monitor the mixed gas in real time.
[0003] However, traditional monitoring devices detect pipes by placing probes inside the pipes, neglecting factors such as high fluidity and the presence of particulate dust inside the pipes, which can affect the probes, leading to inaccurate monitoring data or even damage to the probes.
[0004] For example, when natural gas is made into the most commonly used mixed gas and transported through pipelines, monitoring devices need to be installed at multiple points inside the pipeline. If the probes installed inside the pipeline are not protected, the fine dust in the gas and the impact of the gas flow will damage the probes over a long period of time, affecting the detection data. Utility Model Content
[0005] This utility model discloses an online monitoring device for mixed gases, aiming to solve the technical problem that traditional monitoring devices, which place a detection probe inside the pipeline and then detect it through the detection device, ignore the fact that the large flow of gas and the presence of particulate dust inside the pipeline can affect the probe, resulting in inaccurate monitoring data or even damage to the probe.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An online monitoring device for a mixed gas includes a tube body and a front seat sleeved on its front side. A rear seat is slidably connected to the rear side of the front seat. An extension seat is fixedly connected to the bottom front side of the front seat. A locking block is fixedly connected to the top of the rear seat. The device also includes: a monitoring mechanism: the monitoring mechanism includes a cylindrical tube fixedly connected to the middle of the front seat. A fixing frame is fixedly connected inside the cylindrical tube. A detection probe is fixedly connected to the middle of the fixing frame. A protective cover is threaded to the rear end of the cylindrical tube. A filter screen is provided inside the protective cover. A delivery pipe is fixedly connected to the front end of the detection probe; and a fixing mechanism: the fixing mechanism is located on the top of the rear seat.
[0008] In this solution, the detection mechanism can effectively protect the detection probe installed inside the pipeline. By adding a protective cover to the outside of the detection probe, the probe can be protected from deformation and damage caused by long-term gas impact, which would affect the accuracy of the detection probe. After the gas passes through the arc-shaped opening on the surface of the protective cover, the filter screen inside the protective cover can block fine dust particles that may be contained in the gas, further protecting the probe. At the same time, the detachable design of the protective cover also facilitates subsequent cleaning of the protective cover and the filter screen.
[0009] In a preferred embodiment, the fixing mechanism includes a rotating seat fixedly connected to the top of the rear seat, a hook slidably connected to the surface of the rotating seat, a rotating rod rotatably connected to the middle of the rotating seat, a nut threadedly connected to the surface of the rotating rod, symmetrical sliding rods provided on the left and right sides of the rotating seat, the rotating seat slidably connected to the surface of the rotating seat sliding rods, a threaded groove being opened at the top of the rotating rod, and the front end of the hook engaging inside the locking block.
[0010] The device can be quickly installed using a fixing mechanism and is suitable for pipes of various sizes. By fitting the front and rear seats onto the front and rear sides of the pipe body, rotating the rotating seat causes the front end of the hook to engage with the locking block, completing the initial fixing of the device. Then, the hook is further fixed by restricting it with the nut on the rotating rod surface. The design of the front and rear seats fitting together can be used for pipes of various sizes, improving the practicality of the device.
[0011] As described above, an online monitoring device for mixed gases includes a tube body and a front seat fitted to its front side. A rear seat is slidably connected to the rear side of the front seat. An extension seat is fixedly connected to the bottom front side of the front seat, and a locking block is fixedly connected to the top of the rear seat. The device also includes: a monitoring mechanism comprising a cylindrical tube fixedly connected to the middle of the front seat, a fixing frame fixedly connected inside the cylindrical tube, a detection probe fixedly connected to the middle of the fixing frame, a protective cover threaded to the rear end of the cylindrical tube, a filter screen disposed inside the protective cover, and a delivery pipe fixedly connected to the front end of the detection probe; and a fixing mechanism disposed on the top of the rear seat. The online monitoring device for mixed gases provided by this utility model has the technical effect of protecting the detection probe and improving its service life and accuracy.

[0018] The online monitoring device for mixed gases disclosed in this utility model is mainly used in scenarios where it is necessary to protect the probe from dust and improve the monitoring accuracy when monitoring mixed gases inside pipelines.
[0019] Reference Figure 1 , Figure 2 and Figure 3 An online monitoring device for a mixed gas includes a tube body 1 and a front seat 2 sleeved on its front side. A rear seat 3 is slidably connected to the rear side of the front seat 2. An extension seat 4 is fixedly connected to the bottom front side of the front seat 2. A locking block 5 is fixedly connected to the top of the rear seat 3. The device also includes: a monitoring mechanism: the monitoring mechanism includes a cylindrical tube 6 fixedly connected to the middle of the front seat 2. A fixing frame 7 is fixedly connected inside the cylindrical tube 6. A detection probe 8 is fixedly connected to the middle of the fixing frame 7. A protective cover 9 is threadedly connected to the rear end of the cylindrical tube 6. A filter screen 10 is provided inside the protective cover 9. A delivery pipe 11 is fixedly connected to the front end of the detection probe 8; and a fixing mechanism: the fixing mechanism is located on the top of the rear seat 3.
[0020] Specifically, by adding a protective cover 9 to the outside of the detection probe 8, the probe can be protected to prevent deformation and damage to the detection probe 8 caused by long-term gas impact, which would affect the accuracy of the detection probe 8. After the gas passes through the arc-shaped opening on the surface of the protective cover 9, the filter screen 10 set inside the protective cover 9 can block the fine dust particles that may be contained in the gas, further protecting the probe. At the same time, the detachable design of the protective cover 9 also facilitates the subsequent cleaning of the protective cover 9 and the filter screen 10.
[0021] The cylindrical tube 6 is inserted into the tube body 1 at its rear end. The rear end surface of the cylindrical tube 6 is provided with a threaded groove. The threaded groove at the rear end of the cylindrical tube 6 can be used to disassemble and assemble the protective cover 9, thereby facilitating the cleaning and maintenance of the interior of the protective cover 9.
[0022] The protective cover 9 has an arc-shaped hole on its surface and a threaded line corresponding to the cylindrical tube 6 on the inner side of the front end of the protective cover 9. The arc-shaped hole on the surface of the protective cover 9 can ensure that the gas can contact the detection probe 8 while reducing the impact of the gas.
[0023] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the fixing mechanism includes a rotating seat 12 fixedly connected to the top of the rear seat 3, a hook 13 slidably connected to the surface of the rotating seat 12, a rotating rod 14 rotatably connected to the middle of the rotating seat 12, and a nut 15 threadedly connected to the surface of the rotating rod 14.
[0024] Specifically, by fitting the front seat 2 and the rear seat 3 onto the front and rear sides of the pipe body 1, rotating the rotating seat 12 causes the front end of the hook 13 to engage with the locking block 5, thus completing the initial fixation of the device. Then, the hook 13 is further fixed by restricting it with the nut 15 on the surface of the rotating rod 14. The design of fitting the front seat 2 and the rear seat 3 together can be applied to pipes of various sizes.
[0025] The rotating seat 12 has symmetrical sliding rods on its left and right sides. The rotating seat 12 is slidably connected to the surface of the sliding rods. The top of the rotating rod 14 has a threaded groove. The front end of the hook 13 is engaged inside the locking block 5. The device is quickly fixed by the quick engagement of the hook 13 and the locking block 5, which facilitates installation.
[0026] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a composite gas detector 16 is placed inside the extension seat 4. The top of the composite gas detector 16 is fixedly connected to the front end of the delivery pipe 11. Sealing gaskets are provided on the inner sides of the front seat 2 and the rear seat 3.
[0027] Specifically, the sealing gaskets on the inner sides of the front seat 2 and the rear seat 3 can increase the fit with the tube body 1 and prevent the gas inside the tube body 1 from leaking out through the opening.
[0028] Working principle: In use, first install the device. A circular hole is made on the surface of the tube body 1 to facilitate the insertion of the cylindrical tube 6. Insert the cylindrical tube 6 into the hole, simultaneously ensuring the inner side of the front seat 2 is against the front side of the tube body 1. The sealing gasket on the inner side of the front seat 2 increases the sealing at the opening of the tube body 1, preventing gas leakage. Then, insert the bottom of the rear seat 3 into the bottom of the front seat 2. Rotate the rotating seat 12, and slide the hook 13 to engage with the locking block 5. Next, rotate the rotating rod 14 until it is positioned in the groove on the inner surface of the hook 13. Rotate the nut 15 until it is aligned with the front side of the hook 13 along the rotating rod 14, completing the device's fixation. Then, place the composite gas detector 16 in the extension seat 4 and connect it to the delivery pipe 11. The mixed gas inside the tube 1 can then be detected. During the detection, the protective cover 9 on the outside of the detection probe 8 can prevent long-term gas impact from causing deformation and damage to the detection probe 8, thus affecting the accuracy of the detection probe 8. After the gas passes through the arc-shaped opening on the surface of the protective cover 9, the filter screen 10 set inside the protective cover 9 can block the fine dust particles that may be contained in the gas, further protecting the probe. At the same time, the detachable design of the protective cover 9 also facilitates the subsequent cleaning of the protective cover 9 and the filter screen 10.
