Description

Technical Field

[0001] This utility model relates to the field of odorizer technology, specifically to an automatic odorizer detection device for an automatic odorizer. Background Technology

[0002] An automatic odorizer is a device used to add odorants to gases such as natural gas and liquefied petroleum gas (LPG). Since natural gas and LPG are colorless and odorless, leaks are difficult to detect and pose a safety hazard. Therefore, by adding odorants (such as tetrahydrothiophene), a distinct odor can be produced when a gas leak occurs, making it easier for people to detect and take timely action.

[0003] The natural gas station first adds the canned odorant to the odorizer, which then introduces the odor into the gas pipeline. However, the existing odorizer cannot provide real-time information on the odorant content in the natural gas pipeline after odorization, necessitating timely odorant monitoring of the pipeline. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic detection device for odorizing agents in automatic odorizers, thus solving the existing technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic odorant detection device for an automatic odorizer includes a gas supply pipe, a guide pipe connected to the gas supply pipe is installed on the side wall of the gas supply pipe, a gas distribution hood and a detection component are installed on the guide pipe, the side wall of the gas distribution hood is provided with equidistantly distributed self-sealing structures, and the inner side of the gas distribution hood is provided with a partition that divides its inner cavity into four equal parts. The gas distribution hood and the partition are movably connected to the guide pipe. The detection component on the guide pipe includes a circular plate, a detection head, a breathable ring and a negative pressure suction head. The circular plate is fixed to the guide pipe, and three breathable rings are installed on the circular plate. The detection head and the negative pressure suction head are respectively installed in two of the symmetrical breathable rings.

[0007] Preferably, the self-sealing structure includes a vent frame, a spring, and a sealing block. The vent frame is fixed to the inner wall of the air distribution hood, and a spring is provided on the inner side of the vent frame to provide elastic reset for the sealing block. The sealing block is movably connected to a pre-set circular hole on the side wall of the air distribution hood.

[0008] Preferably, the sealing block includes a disc portion and a hemispherical portion, with the hemispherical portion being movably connected to the vent ring.

[0009] Preferably, a servo motor is installed on the outside of the gas supply pipe, and a gear is installed at the output end of the servo motor. The gear is movably connected to the outer wall of the gas distribution hood.

[0010] This utility model provides an automatic odorant detection device for an automatic odorizer, which has the following advantages compared with the prior art:

[0011] This automatic odorizer uses an automatic odorant detection device installed on the side wall of the gas pipeline. The odorous natural gas in the pipeline fills the gas delivery pipe and can also diffuse into the gas distribution hood. The side wall of the gas distribution hood has equidistantly distributed self-sealing structures. In the initial state, the elasticity of the spring forces the sealing block to block the round hole on the side wall of the gas distribution hood, preventing leakage of odorous natural gas. The inside of the gas distribution hood is divided into a collection chamber, a detection chamber, an exhaust chamber, and a clean air chamber by four partitions. When the automatic odorant detection device is in use, the concentration of odorant can be detected once every time the servo motor drives the gear to rotate the gas distribution hood by 90 degrees. At the same time, the previous detection does not affect the accuracy of the next detection, making it highly practical. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-6This utility model provides an automatic odorant detection device for an automatic odorizer, including a gas supply pipe 1. A guide pipe 2, connected to the gas supply pipe 1, is installed on the side wall of the gas supply pipe 1, allowing the odorous natural gas in the gas supply pipe 1 to enter the guide pipe 2. A gas distribution hood 3 and a detection component 4 are installed on the guide pipe 2, allowing the odorous natural gas to diffuse into the gas distribution hood 3. The side wall of the gas distribution hood 3 has equidistantly distributed self-sealing structures 32. The inner side of the gas distribution hood 3 has partitions 31 that divide its internal space into four equal parts. The inner side of the gas distribution hood 3 is divided into a collection chamber, a detection chamber, an exhaust chamber, and a clean air chamber by the four partitions 31. Natural gas diffuses from the gas duct 2 into the collection chamber. The gas distribution hood 3 and the partition 31 are both movably connected to the gas duct 2. The detection assembly 4 on the gas duct 2 includes a circular plate 41, a detection head 42, a breathable ring 43, and a negative pressure suction head 44. The circular plate 41 is fixed to the gas duct 2. Three breathable rings 43 are installed on the circular plate 41. The detection head 42 and the negative pressure suction head 44 are respectively installed in two of the symmetrical breathable rings 43. The breathable rings 43 are in contact with the self-sealing structure 32. When the end of the self-sealing structure 32 is movably connected to the breathable ring 43, the deformation of the self-sealing structure 32 will cause the gas inside the gas distribution hood 3 to diffuse.

[0021] The self-sealing structure 32 includes a vent frame 321, a spring 322, and a sealing block 323. The vent frame 321 is fixed to the inner wall of the gas distribution hood 3. The inner side of the vent frame 321 is provided with a spring 322 to provide elastic reset for the sealing block 323. The sealing block 323 is movably connected to a pre-set circular hole on the side wall of the gas distribution hood 3. In the initial state, the elasticity of the spring 322 forces the sealing block 323 to block the circular hole on the side wall of the gas distribution hood 3. When the gas distribution hood 3 moves, the self-sealing structure 32 on the side wall of the gas distribution hood 3 rotates accordingly, and the self-sealing structure 32 will contact the vent ring 43. The odorous natural gas inside the gas distribution hood 3 then diffuses into different vent rings 43.

[0022] The sealing block 323 includes a disc portion and a hemispherical portion. The hemispherical portion is movably connected to the vent ring 43. When the self-sealing structure 32 on the side wall of the air distribution hood 3 comes into contact with the vent ring 43, the vent ring 43 comes into contact with the hemispherical portion of the sealing block 323, causing the sealing block 323 to move laterally. The sealing block 323 no longer blocks the circular hole on the side wall of the air distribution hood 3.

[0023] A servo motor 5 is installed on the outside of the gas pipe 1. A gear 6 is installed at the output end of the servo motor 5. The gear 6 is movably connected to the outer wall of the gas distribution hood 3. The servo motor 5 drives the gear 6 to rotate the gas distribution hood 3 in an adaptive manner.

[0024] Working Principle: This automatic odorizer uses an automatic odorant detection device installed on the side wall of the gas supply pipe 1. The odorous natural gas in the gas supply pipe 1 fills the gas guide pipe 2, and can also diffuse into the gas distribution hood 3. The side wall of the gas distribution hood 3 has equidistantly distributed self-sealing structures 32. In the initial state, the elasticity of the spring 322 forces the sealing block 323 to block the round hole on the side wall of the gas distribution hood 3, preventing leakage of the odorous natural gas. The inside of the gas distribution hood 3 is divided into a collection chamber, a detection chamber, an exhaust chamber, and a clearance chamber by four partitions 31. The collection chamber is always in the southeast direction (as shown in the attached diagram), the detection chamber is always in the northeast direction (as shown in the attached diagram), the exhaust chamber is always in the northwest direction (as shown in the attached diagram), and the clearance chamber is always in the southwest direction (as shown in the attached diagram). Thus, the collection chamber is filled with odorous natural gas. Then, the servo motor 5 drives the gear 6 to rotate the gas distribution hood 3 90 degrees, allowing the odorous natural gas to enter the detection chamber. Simultaneously, the sealing block 3... Block 323 is squeezed by the venting ring 43 and undergoes lateral displacement. Block 323 no longer blocks the round hole on the side wall of the gas distribution hood 3. The odorous natural gas comes into contact with the detection head 42 along the venting ring 43. The detection head 42 detects the odorous natural gas with an odorant. Then, the servo motor 5 drives the gear 6 to rotate the gas distribution hood 3 90 degrees, and the odorous natural gas enters the exhaust chamber. At the same time, the block 323 no longer blocks the round hole on the side wall of the gas distribution hood 3, and the odorous natural gas diffuses into the atmosphere. Then, the servo motor 5 drives the gear 6 to rotate the gas distribution hood 3 90 degrees, and the odorous natural gas enters the empty chamber. At the same time, the block 323 no longer blocks the round hole on the side wall of the gas distribution hood 3, and the negative pressure suction head 44 performs negative pressure suction on the empty chamber. In this way, the odorous natural gas in the empty chamber is cleaned up. When the gas distribution hood 3 rotates 90 degrees again, the empty chamber, as a "collection chamber", will not be affected by the previous detection. When the entire automatic odorant detection device is in use, the concentration of odorant can be detected once every time the servo motor 5 drives the gear 6 to rotate the gas distribution hood 3 by 90 degrees. At the same time, the previous detection does not affect the accuracy of the next detection, making it highly practical.

[0025] In summary: This automatic odorizer uses an automatic odorant detection device installed on the side wall of the gas supply pipe 1. The odorous natural gas in the gas supply pipe 1 fills the gas guide pipe 2, and can also diffuse into the gas distribution hood 3. The side wall of the gas distribution hood 3 is provided with equidistantly distributed self-sealing structures 32. In the initial state, the elasticity of the spring 322 forces the sealing block 323 to block the round hole on the side wall of the gas distribution hood 3, preventing leakage of the odorous natural gas.

[0026] The inner side of the gas distribution hood 3 is divided into a collection chamber, a detection chamber, an exhaust chamber, and a clean air chamber by four partitions 31. When the odorant automatic detection device is in use, the concentration of the odorant can be detected once each time the servo motor 5 drives the gear 6 to rotate the gas distribution hood 3 by 90 degrees. At the same time, the previous detection does not affect the accuracy of the next detection, making it highly practical.
