[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an ambient air nitrogen oxide sampling device, including a telescopic support assembly 1, a bottom support assembly 6 is provided above the telescopic support assembly 1, the telescopic support assembly 1 and the bottom support assembly 6 are connected by a threaded connector 7, a sampler main body assembly 5 is provided above the bottom support assembly 6, equipment mounting assemblies 3 are installed on both sides of the sampler main body assembly 5, the bottom support assembly 6 and the sampler main body assembly 5 are connected by a gas supply protection device 2, and an auxiliary fixing device 4 is fixedly installed on one side of the telescopic support assembly 1.

[0023] Specifically, the gas supply protection device 2 includes a connecting box 21, a gas supply pipe 22, a nozzle 23, a protection component 24, a hose 25, and a fan 26. The bottom support component 6 is connected to the main body component 5 of the sampler through the connecting box 21. The fan 26 is fixedly installed below the connecting box 21 and on one side of the bottom support component 6. The hose 25 is fixedly installed below the air inlet of the fan 26. The gas supply pipe 22 is fixedly installed above the connecting box 21 and on one side of the two equipment mounting components 3. Multiple nozzles 23 are fixedly installed on the side of the gas supply pipe 22 near the two equipment mounting components 3. The protection component 24 is provided on the outside of the main body component 5 of the sampler.

[0024] By adopting the above technical solution, staff can use the combination of hose 25 and fan 26 to send nitrogen oxides from a distance to the outside of the main component 5 of the sampler when needed, thus facilitating the sampling of nitrogen oxides from a distance.

[0025] Specifically, the gas transmission protection device 2 also includes a screen 27, and the screen 27 is fixedly installed at the end of the hose 25 away from the fan 26.

[0026] By adopting the above technical solution, the device can prevent external impurities from entering the interior of the hose 25 through the partition 27, thereby reducing the possibility of damage and blockage to structures such as the fan 26, and thus ensuring normal operation.

[0027] Specifically, the protective component 24 includes a protective shell 241, a movable plate 242, and an electric telescopic rod 243. The protective shell 241 is provided on the outside of the sampler main component 5. The movable plate 242 is fixedly installed below the protective shell 241 and on one side of the connecting box 21. The connecting box 21 and the movable plate 242 are connected by the electric telescopic rod 243.

[0028] By adopting the above technical solution, staff can protect the main component 5 of the sampler by using the protective shell 241 and the electric telescopic rod 243 when needed, thereby reducing the possibility of accidental damage to the main component 5 of the sampler.

[0029] In this embodiment, when the device is needed to sample nitrogen oxides in ambient air, the operator connects the telescopic support assembly 1 to the bottom support assembly 6 via the threaded connector 7. Then, the operator manipulates the telescopic support assembly 1 to adjust the height of the sampler main assembly 5 and the equipment mounting assembly 3. Then, the operator activates the electric telescopic rod 243 in the protective assembly 24 of the gas supply protection device 2, thereby moving the moving plate 242 and the protective shell 241 until the protective shell 241 leaves the outside of the sampler main assembly 5. If it is necessary to sample nitrogen oxides in the surrounding air, the sampler main assembly 5 can be directly activated for sampling. If it is necessary to sample nitrogen oxides in the air at a distance, the end of the hose 25 can be placed at the sampling position, and the fan 26 can be activated. Under the action of the fan 26, the air at the sampling position passes through the mesh 27, hose 25, connecting box 21, gas supply pipe 22 and each nozzle 23 and is blown out, so that the air at the sampling position surrounds the sampler main assembly 5. Then, the sampler main assembly 5 can be activated for sampling.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the auxiliary fixing device 4 includes a support plate 41, a lead screw 42, a lifting frame 43, and a cone 44. The support plate 41 is fixedly installed on one side of the telescopic support assembly 1. The lead screw 42 is installed above the support plate 41. The lifting frame 43 is installed on the outside of the lead screw 42 by thread. Multiple cones 44 are fixedly installed below the lifting frame 43.

[0032] By adopting the above technical solution, the staff can use the cooperation of the lead screw 42 and the cone 44 to fix the position of the device when needed, thereby reducing the possibility of the device moving accidentally due to external collisions or other reasons.

[0033] Specifically, one side of the support plate 41 is in contact with the inner side of the lifting frame 43.

[0034] By adopting the above technical solution, the device can limit the movement of the lifting frame 43 by the support plate 41, thereby preventing the lifting frame 43 from rotating and deviating during the movement, thus ensuring the normal operation of the work.

[0035] In this embodiment, when it is necessary to assist in fixing the position of the device, the operator rotates the lead screw 42 in the auxiliary fixing device 4. The lead screw 42 is threadedly connected to the lifting frame 43, and one side of the support plate 41 is in contact with the inner side of the lifting frame 43. Therefore, the lead screw 42 drives the lifting frame 43 to descend until each of the insertion cones 44 is driven into the ground, thereby providing a certain degree of auxiliary fixing of the device's position and reducing the possibility of the device moving accidentally due to external collisions or other reasons.

[0036] The structure and principle of the telescopic support assembly 1, the equipment mounting assembly 3 consisting of a hook, a fixed connecting frame, mounting holes, slots, and an adjusting plate, the sampler body assembly 5 consisting of the sampler body, a handle, and a snap-fit ​​placement assembly, the bottom support assembly 6, and the threaded connector 7 in this utility model have been disclosed in an ambient air nitrogen oxide sampling device disclosed in Chinese Patent Application No. 202322020569.1. Its working principle is as follows: when using the ambient air nitrogen oxide sampling device, firstly, during use, the support base plate and support legs at the bottom of the device are connected and fixed for support and tightening, making the device stable and non-adjustable. A threaded connector is provided in the middle of the bottom end of the support base plate, which can be threadedly connected to the rotating connector. Then, the telescopic rod at the bottom end can be height adjusted, and a counterweight base plate is provided at the bottom end for counterweight fixation, allowing for placement in different positions. The device is designed for use by hanging the sampler on both sides of the main body using hooks, allowing for easy snap-fit ​​fixing of Equipment Installation Components 1 and 2. Glassware is placed inside the fixing frame via mounting holes, and the central adjustment plate allows for vertical adjustment, facilitating the placement of different containers and simplifying disassembly and cleaning. Equipment Installation Component 2 has a slider on its inner side that matches the slot inside the fixing frame, allowing Equipment Installation Components 1 and 2 to be interlocked and stacked. Disassembly reduces the storage space. The combination of the snap-fit ​​receiving frame and the compression pad allows for the placement of Equipment Installation Components 1 and 2, as well as the telescopic support component, after disassembly and reassembly, improving product storage capacity and portability. This is the working principle of this ambient air nitrogen oxide sampling device.

[0037] The working principle and usage process of this utility model are as follows: When it is necessary to use the device to sample nitrogen oxides in ambient air, the operator connects the telescopic support assembly 1 to the bottom support assembly 6 through the threaded connector 7. Then, the operator manipulates the telescopic support assembly 1 to adjust the height of the main body assembly 5 of the sampler and the equipment mounting assembly 3. Then, the operator activates the electric telescopic rod 243 in the protective assembly 24 of the gas supply protection device 2, thereby moving the moving plate 242 and the protective shell 241 until the protective shell 241 moves away from the outside of the main body assembly 5 of the sampler. If it is necessary to sample nitrogen oxides in the surrounding air, the main body assembly 5 of the sampler can be activated directly for sampling. If it is necessary to sample nitrogen oxides in the air at a distance, the end of the hose 25 can be placed at the sampling position. Set up the sampling device and start the fan 26. Under the action of the fan 26, the air at the sampling position passes through the partition 27, hose 25, connecting box 21, air supply pipe 22 and each nozzle 23 and blows out, so that the air at the sampling position surrounds the main component 5 of the sampler. Then start the main component 5 of the sampler to perform sampling. When it is necessary to assist in fixing the position of the device, the operator rotates the screw 42 in the auxiliary fixing device 4. The screw 42 is threadedly connected to the lifting frame 43, and one side of the support plate 41 is in contact with the inner side of the lifting frame 43. Therefore, the screw 42 drives the lifting frame 43 to descend until each of the insertion cones 44 is driven into the ground, thereby providing a certain degree of auxiliary fixing of the position of the device and reducing the possibility of the device moving accidentally due to external collisions or other reasons.
