[0013] After adopting the above technical solution, the effect of the present invention is as follows: since the ozone sampling device in the environment includes a lower shell and an upper cover plate, a detachable locking structure is provided 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, and the upper chamber is divided into an outer chamber and an inner chamber by a sampling retaining ring, a plurality of light-transmitting storage cylinders for hanging and storing U-shaped absorption tubes are fixedly installed in the outer chamber, and an air inlet branch pipe and an air outlet branch pipe connected to the U-shaped absorption tube are further provided in the storage cylinder, and the air inlet branch pipe and the air outlet branch pipe penetrate the detection partition and enter the lower chamber, and a collecting air inlet branch pipe and an air outlet branch pipe are provided in the lower chamber.

The absorbance obtained by the light source through the unsampled U-shaped absorption tube 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 of the air intake branch is closed, and the solenoid valve of the next air intake branch is opened. At the same time, the lighting source and the light intensity detection sensor are rotated, and the sampling and detection are restarted until the required number of U-shaped absorption tubes are sampled. Then all the solenoid valves can be closed, the upper cover can be opened, the U-shaped absorption tube can be taken out, and subsequent detection can be carried out. The device can automatically perform absorbance detection after sampling with multiple U-shaped absorption tubes, ensuring accurate sampling, effective light protection, and reducing manual tediousness.

[0014] Since a hanging plate is fixedly installed on the upper end of the U-shaped absorption tube, a hanging retaining ring corresponding to the hanging plate is provided in the storage tube, and a supporting base is provided at the bottom of the U-shaped absorption tube. When the hanging plate is hung on the hanging retaining ring, the supporting base is in contact with and supported by the bottom of the storage tube, and the air inlet branch pipe and the air outlet branch pipe are connected to the air inlet and air outlet of the U-shaped absorption tube through an adapter; the U-shaped absorption tube can be suspended and installed by the hanging plate, and the bottom supporting base can also provide stable support, which facilitates the assembly and disassembly of the U-shaped absorption tube and improves the utilization efficiency.

[0015] Since the upper cover is located below and a turntable is rotatably installed, the turntable is connected to an illumination light source extending into the inner cavity through a rotating shaft, and the rotation driving device includes a driving motor, and a driving gear and a driven gear are rotatably installed on the upper cover, the driving gear is connected to the output shaft of the driving motor, the rotating shaft passes through the upper cover and is fixedly connected to the driven gear, and a synchronization rod extends along the radial direction of the rotating shaft on the turntable, and a light intensity detection sensor is fixedly installed on the synchronization rod, and the light intensity detection sensor corresponds to the illumination light source; after the driving motor drives the driving gear to rotate and drives the driven gear to rotate, the illumination light source can be rotated to align with the storage tube for the required detection sample, and after the synchronization rod is fixedly connected to the turntable, it can ensure synchronization with the rotation of the illumination light source, and the absorbance detection is accurate.

[0016] Furthermore, since an upper cover is provided on the upper cover plate, an upper cover chamber is formed between the upper cover plate and the upper cover, the driving gear and the driven gear are rotatably mounted in the upper cover chamber, and the drive motor is fixedly mounted on the upper cover; the upper cover can improve the protection effect during use, ensure that the outside world will not affect the transmission of the driving gear and the driven gear, and the drive is stable and reliable.

[0018] Furthermore, since the air inlet branch pipe and the air outlet branch pipe located in the storage cylinder are vertical hard pipes, the air inlet branch pipe and the air outlet branch pipe in the lower chamber are hoses connected to the air inlet main pipe and the air outlet main pipe, and the air pump is fixedly installed at the bottom of the lower chamber; the vertical hard pipe is used for convenient connection when placing the U-shaped absorption tube, and then the bottom is passed through the hose to reduce the occupied space, making the overall structure compact and improving practicality.

[0019] Since the upper cover is provided with a groove that cooperates with the lower shell, the locking structure is a buckle installed on the upper cover and the side wall of the lower shell; the upper cover is conveniently mounted on the lower shell through the groove, and then fixed by the buckle, which has a simple structure and is easy to operate.

[0020] Furthermore, since a handle for easy lifting is provided on the lower shell, it is convenient for manual movement through the handle, ensuring that it is easy to move and carry. BRIEF DESCRIPTION OF THE DRAWINGS
