Description

Technical Field

[0001] This utility model belongs to the technical field of gas detection and monitoring, specifically relating to a gas pipeline leak detection device. Background Technology

[0002] A gas pipeline leak detection device is a specialized piece of equipment used to monitor and identify leaks in gas pipelines. It typically consists of sensors, a signal acquisition module, a data processing system, and an alarm device. By installing detection points along the pipeline, it collects real-time data on parameters such as gas concentration, pressure, and flow rate inside the pipeline or in the surrounding environment. This data is then transmitted to a monitoring system for analysis, enabling timely detection and response to gas leaks.

[0003] Currently, during long-term use, dust, microfibers, or oily particles easily accumulate on the surface and vents of the probe protective cover. These deposits gradually block the channels, slowing down the speed at which external gas enters the detection area, thus affecting the probe's sensitive response to leaked gas.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1-5 This is an embodiment of the present invention, which provides a gas pipeline leak detection device, including,

[0030] The conveying mechanism 100 includes a tube body 110 and a fixed seat 120 fixedly installed on the top of the tube body 110;

[0031] The dustproof mechanism 200 includes a support shell 210 that is movably mounted in the inner cavity of the tube body 110, an inner filter assembly 220 disposed in the inner cavity of the support shell 210, and a flow guiding assembly 230 disposed in the inner cavity of the inner filter assembly 220.

[0032] The coordinated operation of the conveying mechanism 100 and the dustproof mechanism 200 effectively improves the stability and reliability of gas pipeline leak detection. The pipe body 110 and the fixed seat 120 form a stable conveying structure to ensure the smooth flow of gas. The support shell 210, the inner filter assembly 220 and the flow guiding assembly 230 together form a multi-layer dustproof system, which can efficiently filter impurities in the gas and prevent dust and particulate matter from interfering with the detection accuracy, thereby extending the service life of the device and improving the detection accuracy.

[0033] Specifically, the dustproof mechanism 200 also includes a guide rail 240 fixedly installed in the inner cavity of the tube body 110, a channel 250 opened on the top of the support shell 210, a filter screen 260 movably locked in the ventilation part at the bottom of the support shell 210, and a magnetic seat 270 fixedly installed on the top of the support shell 210.

[0034] The dustproof mechanism 200 achieves the detachable and adjustable installation of the support shell 210 through the sliding cooperation of the guide rail 240 and the channel 250, which facilitates quick cleaning or replacement of the internal filter components. The filter screen 260 is set in the ventilation section to effectively intercept large particulate impurities and reduce the load on the subsequent filter components. The introduction of the magnetic seat 270 enhances the fixation stability of the inner structure and ensures that the filter components will not be displaced or loosened under the impact of airflow.

[0035] Furthermore, the inner filter assembly 220 includes a partition 221 that is movably mounted in the inner cavity of the support housing 210, a magnetic block 222 that is fixedly mounted on the bottom of the partition 221, and a limiting track 223 that is fixedly mounted in the inner cavity of the partition 221.

[0036] In the inner filter assembly 220, the baffle 221 is quickly positioned and fixed by the magnetic block 222 adsorbing the external magnetic seat 270, which simplifies the disassembly and assembly process. The addition of the limiting track 223 further constrains the movement trajectory of the flow guiding assembly 230, preventing it from deviating from the preset position due to airflow disturbance. Through layered filtration and precise limiting, the interception efficiency of fine particles is significantly improved, while the airflow distribution is optimized and the interference of turbulence on the detection signal is reduced.

[0037] Preferably, the flow guiding assembly 230 includes a flow guiding plate 231 that is movably mounted in the inner cavity of the limiting track 223, a through hole 232 opened on the top of the flow guiding plate 231, and a flow guiding groove 233 opened on the outer side of the flow guiding plate 231, wherein the through hole 232 and the flow guiding groove 233 communicate with each other.

[0038] The flow guiding component 230 slides in conjunction with the limiting track 223 of the flow guiding plate 231, and can automatically adjust its angle according to the airflow speed to ensure that the gas passes evenly through the through hole 232 and the flow guiding groove 233. This dynamic flow guiding design not only reduces airflow resistance, but also guides the gas to the detection area through the through-flow channel, avoiding the detection blind zone caused by local eddies. The specific arrangement of the flow guiding groove 233 further enhances the impurity separation effect, enabling the detection probe 140 to capture the leakage signal more accurately.

[0039] It should be noted that there are four magnetic bases 270, which are evenly distributed on the top of the support shell 210. The number of magnetic blocks 222 is the same as that of magnetic bases 270, and they are located on the top of the magnetic bases 270 to achieve magnetic attraction.

[0040] In this design, the inner filter component 220 and the support shell 210 are fixed together by the evenly distributed magnetic bases 270 and the corresponding number of magnetic blocks 222. This symmetrical magnetic layout greatly improves the vibration resistance and sealing performance of the overall structure. Even under high pressure or pulsed airflow conditions, it can effectively prevent the components from falling off or leaking. At the same time, the magnetic connection method facilitates quick disassembly and maintenance, taking into account both stability and convenience.

[0041] Furthermore, the conveying mechanism 100 also includes a detector 130 fixedly installed on the top of the fixed base 120, and a detection probe 140 fixedly installed on the bottom of the detector 130. The dustproof mechanism 200 is located close to the upper part of the inner cavity of the tube body 110, and the detection probe 140 extends into the interior of the inner filter assembly 220.

[0042] The detector 130 and detection probe 140 added to the conveying mechanism 100 are directly fixed to the mounting base 120, forming an integrated detection unit. The detection probe 140 extends deep into the inner filter assembly 220, enabling real-time monitoring of the purified gas and avoiding external environmental interference. This design shortens the signal transmission path and improves the response speed. Simultaneously, the rigid connection avoids misjudgments caused by probe vibration, making it particularly suitable for high-sensitivity leak detection scenarios. The dustproof mechanism 200 is positioned close to the upper part of the inner cavity of the tube body 110. Combined with the extended design of the detection probe 140, it fully utilizes the upward floating characteristics of gas flow, allowing impurities to naturally settle under gravity, reducing the probability of the probe contacting contaminants. The detection probe 140 penetrates the structure of the inner filter assembly 220, ensuring direct contact with the filtered gas, further eliminating the negative impact of dust adsorption on the detection results and significantly improving data reliability.

[0043] In use, the gas first enters the system through the pipe 110 of the conveying mechanism 100. When passing through the dustproof mechanism 200, it is first coarsely filtered by the filter screen 260 at the bottom of the support shell 210. Then, the airflow is evenly passed through the fine filter layer of the inner filter assembly 220 under the guidance of the guide plate 231 of the guide assembly 230. Impurities are intercepted step by step. The purified gas flows to the upper part of the pipe 110. The gas composition is monitored in real time by the detector 130 fixed on the fixed base 120 through the detection probe 140. When a leak is detected, the system can alarm in time. The guide groove 233 and the through hole 232 ensure that the airflow passes through stably, realizing continuous and reliable leak detection.

[0044] In summary, the tube 110 and the fixed base 120 in the conveying mechanism 100 form a stable gas flow channel, ensuring stable airflow delivery. The dustproof mechanism 200, through the cooperation of the support shell 210, the inner filter assembly 220, and the dynamic flow guiding assembly 230, efficiently intercepts dust and particulate matter, ensuring a clean detection environment. The detection probe 140 penetrates deep into the core area of ​​the filtered airflow to directly monitor the purified gas, avoiding interference signals, optimizing airflow distribution, reducing the impact of turbulence, and also possessing anti-vibration and anti-fall-off characteristics. It is suitable for complex working conditions such as high pressure and high dust, significantly improving detection accuracy and equipment reliability.
