Description

Technical Field

[0001] This utility model relates to the field of ozone detection technology, and in particular to an ozone sampling device in the environment. Background Technology

[0002] Ozone can fade most organic pigments, slowly corrode rubber and cork, and oxidize unsaturated organic compounds. It is commonly used for: disinfection and sterilization of beverages, air purification, bleaching, water treatment and drinking water disinfection, and killing mold and insect eggs in grain warehouses. Ozone has extremely strong oxidizing and bactericidal properties and is one of the strongest oxidants in nature. Ozone is also an important chemical material in industry. However, excessive ozone concentration can be harmful to the human body, so the ozone concentration needs to be monitored at all times in industrial production.

[0003] Currently, when conducting environmental ozone detection, ozone absorbent is placed inside a U-shaped porous glass plate absorption tube. The inlet and outlet of the tube are then connected to air circuits, with an environmental air pump connected to the inlet to blow air through the tube. This allows ambient air to effectively pass through the ozone absorbent. The tube is brown to minimize light exposure. However, this method makes it difficult to determine when the ozone absorbent is saturated, affecting detection accuracy. Furthermore, the ambient air sampling time is long, requiring manual replacement of samples and reliance on experience to determine sampling time, which is cumbersome and labor-intensive.

[0006] As a preferred embodiment, a suspension plate is fixedly installed at the upper end of the U-shaped absorption tube, and a suspension retaining ring corresponding to the suspension plate is provided inside the storage cylinder. A support base is provided at the bottom of the U-shaped absorption tube. When the suspension plate is hung on the suspension retaining ring, the support base contacts and supports the bottom of the storage cylinder. The air inlet pipe and the air outlet pipe are connected to the air inlet and air outlet of the U-shaped absorption tube through adapters.

[0007] As a preferred embodiment, a turntable is rotatably mounted on the lower part of the upper cover plate. The turntable is connected to a lighting source extending into the inner cavity via a rotating shaft. The rotation drive device includes a drive motor. A driving gear and a driven gear are rotatably mounted on the upper cover plate. The driving gear is connected to the output shaft of the drive motor. The rotating shaft passes through the upper cover plate and is fixedly connected to the driven gear. A synchronizing rod extends radially from the turntable along the rotating shaft. A light intensity detection sensor is fixedly mounted on the synchronizing rod, and the light intensity detection sensor corresponds to the lighting source.

[0008] As a preferred embodiment, the upper cover plate is provided with an upper cover cover, and an upper cover cavity is formed between the upper cover plate and the upper cover cover. The driving gear and the driven gear are rotatably installed in the upper cover cavity, and the drive motor is fixedly installed on the upper cover cover.

[0009] As a preferred embodiment, the limiting device is a photoelectric switch, which is mounted on a synchronizing rod, and a sensing plate corresponding to the storage cylinder is fixedly installed on the side wall of the upper chamber.

[0010] As a preferred embodiment, the air inlet and air outlet pipes located inside the storage cylinder are vertical rigid pipes, while the air inlet and air outlet pipes in the lower chamber are flexible pipes connected to the main air inlet and main air outlet pipes.

[0011] As a preferred embodiment, the upper cover plate is provided with a groove that mates with the lower housing, and the locking structure is a latch installed on the side wall of the upper cover plate and the lower housing.

[0012] As a preferred embodiment, the lower housing is provided with a handle for easy lifting.

[0013] After adopting the above technical solution, the effect of this utility model is as follows: The ozone sampling device in the environment includes a lower shell and an upper cover plate, with a detachable locking structure between the lower shell and the upper cover plate. The lower shell is divided into an upper chamber and a lower chamber by a detection partition. The upper chamber is divided into an outer chamber and an inner chamber by a sampling retaining ring. Multiple light-transmitting storage cylinders for suspending and storing U-shaped absorption tubes are fixedly installed in the outer chamber. Each storage cylinder also contains an inlet pipe and an outlet pipe connected to the U-shaped absorption tube. The inlet pipe and outlet pipe pass through the detection partition and enter the lower chamber. The lower chamber contains a combined inlet pipe and an outlet pipe. The system includes an inlet manifold and an outlet manifold. Each inlet manifold is equipped with a corresponding solenoid valve. The inlet manifold is connected to a suction pump, whose suction pipe passes through the lower housing and connects to the outside. The outlet manifold also passes through the lower housing and connects to the outside. The sampling retaining ring has illumination holes corresponding to the storage cylinders. A lighting source that illuminates in one direction is rotatably mounted on the upper cover. The lighting source illuminates the storage cylinders through the illumination holes within the inner cavity. The lighting source is driven to rotate by a rotation drive device. A light intensity detection sensor and a rotation angle limiting device are installed in the outer cavity, rotating synchronously with the lighting source. First, open the top cover to expose the upper chamber. Then, place the corresponding U-shaped absorption tubes into the storage cylinder one by one. The U-shaped absorption tubes contain the corresponding ozone absorption liquid. Next, the suction pump connects to the required sampling point in the outside through the suction pipe. Then, the gas enters the corresponding intake branch pipe through the main intake pipe, ensuring that the solenoid valve of the intake branch pipe is open, allowing the gas to enter the U-shaped absorption tube for absorption by the ozone absorption liquid. Turn on the lighting source and rotate the drive device to drive the lighting source to rotate, so that the lighting source illuminates the storage cylinder that has absorbed the gas. At the same time, the light intensity detection sensor receives the light passing through the storage cylinder and detects the light absorption. The absorbance of the light source obtained through the unsampled U-shaped absorption tube is a standard value. Once the absorbance drops to a certain value, indicating that the ozone absorbent is saturated, the solenoid valve of that intake pipe closes, and the solenoid valve of the next intake pipe opens. At the same time, the lighting source and light intensity detection sensor rotate, and sampling and detection begin again until the required number of U-shaped absorption tubes have been sampled. Then, all solenoid valves can be closed, the top cover can be opened, and the U-shaped absorption tubes can be removed for subsequent testing. This device can automatically sample multiple U-shaped absorption tubes and then perform absorbance detection, ensuring accurate sampling, effectively avoiding light, and reducing manual labor.

[0014] Furthermore, since a suspension plate is fixedly installed at the upper end of the U-shaped absorption tube, and a suspension retaining ring corresponding to the suspension plate is provided inside the storage cylinder, and a support base is provided at the bottom of the U-shaped absorption tube, when the suspension plate is hung on the suspension retaining ring, the support base contacts and supports the bottom of the storage cylinder. The air inlet pipe and air outlet pipe are connected to the air inlet and air outlet of the U-shaped absorption tube through adapters. The U-shaped absorption tube can be suspended and installed through the suspension plate, and the bottom support base can also provide stable support, which facilitates the installation and removal of the U-shaped absorption tube and improves the efficiency of use.

[0015] Furthermore, a turntable is rotatably mounted on the lower part of the upper cover plate. The turntable is connected to an illumination source extending into the inner cavity via a rotating shaft. The rotation drive device includes a drive motor. A drive gear and a driven gear are rotatably mounted on the upper cover plate. The drive gear is connected to the output shaft of the drive motor. The rotating shaft passes through the upper cover plate and is fixedly connected to the driven gear. A synchronizing rod extends radially along the rotating shaft on the turntable. A light intensity detection sensor is fixedly mounted on the synchronizing rod, and the light intensity detection sensor corresponds to the illumination source. By driving the drive gear to rotate through the drive motor, the illumination source can rotate and thus be aligned with the storage cylinder for the required sampling. The fixed connection between the synchronizing rod and the turntable ensures that the rotation is synchronized with the illumination source, resulting in accurate absorbance detection.

[0016] Furthermore, since the upper cover plate is provided with an upper cover cover, an upper cover cavity is formed between the upper cover plate and the upper cover cover. The driving gear and the driven gear are rotatably installed in the upper cover cavity, and the drive motor is fixedly installed on the upper cover cover. The upper cover cover can improve the protection effect during use, ensuring that the external environment will not affect the transmission of the driving gear and the driven gear, and the drive is stable and reliable.

[0017] Furthermore, since the limiting device is a photoelectric switch, which is mounted on the synchronizing rod, and a sensing plate corresponding to the storage cylinder is fixedly installed on the side wall of the upper chamber; when the turntable drives the synchronizing rod to rotate, the photoelectric switch will also rotate, and the contact with the sensing plate ensures that each rotation can be accurately paused, thereby improving the measurement accuracy during sampling.

[0018] Furthermore, since the air inlet and outlet pipes located inside the storage cylinder are vertical rigid pipes, while the air inlet and outlet pipes in the lower chamber are flexible pipes connected to the main air inlet and outlet pipes, and the air pump is fixedly installed at the bottom of the lower chamber; the vertical rigid pipes facilitate connection when placing the U-shaped absorption tube, and the flexible pipes at the bottom reduce the space occupied, making the overall structure compact and improving practicality.

[0019] Furthermore, since the upper cover plate is provided with a groove that mates with the lower housing, the locking structure is a latch installed on the side wall of the upper cover plate and the lower housing; the groove facilitates the upper cover plate to be snapped onto the lower housing, and the latch is used to lock and fix it in place. The structure is simple and the operation is convenient.

[0020] Furthermore, the lower housing is equipped with a handle for easy lifting, making it convenient for manual movement and ensuring easy portability. Attached Figure Description

[0028] The present invention will be further described in detail below through specific embodiments.

[0029] like Figures 1 to 5As shown, an ozone sampling device for the environment includes a lower housing 1 and an upper cover 2. A detachable locking structure is provided between the lower housing 1 and the upper cover 2. The lower housing 1 is divided into an upper chamber and a lower chamber 6 by a detection partition 3. The upper chamber is divided into an outer chamber 5 and an inner chamber 7 by a sampling retaining ring 4. Multiple light-transmitting storage cylinders 9 are fixedly installed in the outer chamber 5 to suspend and store U-shaped absorption tubes 8. The storage cylinders 9 are also provided with an inlet pipe 10 and an outlet pipe 11 communicating with the U-shaped absorption tubes 8. The inlet pipe 10 and the outlet pipe 11 pass through the detection partition 3 and enter the lower chamber 6. The lower chamber 6 is provided with a main inlet pipe 12 and an outlet pipe 13 that combine the inlet pipes 10 and the outlet pipes 11. 3. Each of the air intake manifolds 10 is equipped with a corresponding solenoid valve 14. The main air intake manifold 12 is connected to the air pump 15. The pump pipe 16 of the air pump 15 passes through the lower housing 1 and communicates with the outside. The main air outlet manifold 13 also passes through the lower housing 1 and communicates with the outside. The sampling retaining ring 4 is provided with an illumination hole 17 corresponding to the storage cylinder 9. An illumination source 18 that illuminates in one direction is rotatably installed on the upper cover plate 2. The illumination source 18 illuminates the storage cylinder 9 through the illumination hole 17 in the inner cavity 7. The illumination source 18 is driven to rotate by a rotation drive device. The outer cavity 5 is provided with a light intensity detection sensor 19 that rotates synchronously with the illumination source 18 and a limiting device for limiting the rotation angle.

[0030] like Figure 5 As shown, a hanging plate 20 is fixedly installed at the upper end of the U-shaped absorption tube 8. A hanging retaining ring 21 corresponding to the hanging plate 20 is provided inside the storage cylinder 9. A support base 22 is provided at the bottom of the U-shaped absorption tube 8. When the hanging plate 20 is hung on the hanging retaining ring 21, the support base 22 contacts and supports the bottom of the storage cylinder 9. The air inlet pipe 10 and the air outlet pipe 11 are connected to the air inlet and air outlet of the U-shaped absorption tube 8 through an adapter 23. The U-shaped absorption tube 8 is provided with a pipe for storing ozone absorption liquid. After gas is introduced from the air inlet, it can be effectively discharged from the air outlet without causing the ozone absorption liquid to be discharged. This allows the ozone absorption liquid to effectively react with ozone in the air. The U-shaped absorption tube 8 can be suspended and installed by the hanging plate 20, and the bottom support base 22 can also provide stable support, which facilitates the installation and removal of the U-shaped absorption tube 8 and improves the efficiency of use. The U-shaped absorption tube 8 is a commonly used existing structure on the market, so it will not be described in detail in this article.

[0031] like Figure 2 and Figure 3As shown, a turntable 24 is rotatably mounted on the lower part of the upper cover plate 2. The turntable 24 is connected to an illumination source 18 extending into the inner cavity 7 via a rotating shaft 25. The rotation drive device includes a drive motor 26. A driving gear 27 and a driven gear 28 are rotatably mounted on the upper cover plate 2. The driving gear 27 is connected to the output shaft of the drive motor 26. The rotating shaft 25 passes through the upper cover plate 2 and is fixedly connected to the driven gear 28. A synchronizing rod 29 extends radially from the rotating shaft 25 onto the turntable 24. A light intensity detection sensor 19 is fixedly mounted on the synchronizing rod 29. The light intensity detection sensor 19 is connected to the illumination source... The illumination source 18 corresponds to the light intensity sensor 19. The drive motor 26 drives the active gear 27 to rotate, which in turn drives the driven gear 28 to rotate, so that the illumination source 18 can rotate and be aligned with the storage cylinder 9 to be sampled. The synchronization rod 29 is fixedly connected to the turntable 24 to ensure that it rotates synchronously with the illumination source 18, and the absorbance is accurately detected. The illumination source 18 is an illumination structure corresponding to the light intensity sensor 19. It can be used if it can be pointed to a single point and the light intensity sensor 19 can effectively detect the absorbance after passing through the storage cylinder 9. The light intensity sensor 19 is an existing structure that can be purchased on the market, so it will not be described in detail in the text.

[0032] Furthermore, the upper cover plate 2 is provided with an upper cover cover 30, and an upper cover chamber 31 is formed between the upper cover plate 2 and the upper cover cover 30. The driving gear 27 and the driven gear 28 are rotatably installed in the upper cover chamber 31, and the drive motor 26 is fixedly installed on the upper cover cover 30. The upper cover cover 30 can improve the protection effect during use, ensuring that the external environment will not affect the transmission of the driving gear 27 and the driven gear 28, and the drive is stable and reliable.

[0033] like Figure 3 As shown, the limiting device is a photoelectric switch 32, which is mounted on the synchronizing rod 29. A sensing plate 33 corresponding to the storage cylinder 9 is fixedly installed on the side wall of the upper chamber. When the turntable 24 drives the synchronizing rod 29 to rotate, the photoelectric switch 32 will also rotate. By contacting the sensing plate 33, it ensures that each rotation can be accurately paused, controls the rotation angle, and improves the measurement accuracy during sampling.

[0034] In this embodiment, the air inlet pipe 10 and air outlet pipe 11 located in the storage cylinder 9 are vertical rigid pipes, while the air inlet pipe 10 and air outlet pipe 11 in the lower chamber 6 are flexible pipes connected to the main air inlet pipe 12 and the main air outlet pipe 13. The air pump 15 is fixedly installed at the bottom of the lower chamber 6. The vertical rigid pipes facilitate connection when placing the U-shaped absorption pipe 8, and the flexible pipes at the bottom reduce the space occupied, making the overall structure compact and improving practicality.

[0035] like Figure 2As shown, the upper cover plate 2 is provided with a groove 34 that mates with the lower housing 1. The locking structure is a latch 35 installed on the side wall of the upper cover plate 2 and the lower housing 1. The groove 34 facilitates the upper cover plate 2 to be quickly and accurately attached to the lower housing 1, and the latch 35 is used to lock and fix it in place. The structure is simple and the operation is convenient.

[0036] In this embodiment, the lower housing 1 is provided with a handle 36 for easy lifting; this facilitates manual movement via the handle 36 and ensures convenient carrying.

[0037] The working principle of this embodiment is as follows: First, open the upper cover plate 2 and place the U-shaped absorption tube 8 containing ozone absorbent liquid into the storage cylinder 9. Then, connect the inlet branch pipe 10 and the outlet branch pipe 11 to the inlet and outlet of the U-shaped absorption tube 8 in sequence through the adapter 23. Cover the upper cover plate 2 and secure it with the buckle 35. Next, the suction pump 15 connects to the sampling point in the outside through the suction pipe. Then, the air enters the corresponding inlet branch pipe 10 through the main inlet pipe 12, ensuring that the solenoid valve 14 of the inlet branch pipe 10 is open, allowing gas to enter the U-shaped absorption tube 8 for ozone absorbent liquid absorption. The absorbed air then enters the main outlet pipe 13 through the outlet branch pipe 11 and is discharged. Turn on the lighting source 18, and drive the drive motor 26 to drive the drive gear 27 to drive the driven gear. Gear 28 rotates, driving the illumination source 18 to rotate, so that the illumination source 18 is aimed at the storage cylinder 9 that has absorbed the gas to illuminate it. At the same time, the light intensity detection sensor 19 receives the light passing through the storage cylinder 9 and detects the absorbance. Originally, the absorbance obtained by the illumination source 18 through the unsampled U-shaped absorption tube 8 is a standard value. When the absorbance drops to a certain value, it means that the ozone absorption liquid is saturated. Then, the solenoid valve 14 of the air inlet pipe 10 is closed, and the solenoid valve 14 of the next air inlet pipe 10 is opened. At the same time, the illumination source 18 and the light intensity detection sensor 19 rotate to start sampling and detection again until the required number of U-shaped absorption tubes 8 have been sampled. Then, all the solenoid valves 14 can be closed, the top cover 2 can be opened, the U-shaped absorption tubes 8 can be taken out, and subsequent detection can be carried out.

[0038] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
