Description

Technical Field

[0001] This utility model relates to the field of atmospheric sampler technology, and in particular to a constant temperature and constant flow intelligent atmospheric sampler. Background Technology

[0002] With social development, people have higher and higher requirements for air quality. In order to better detect the local air quality and test the content of various gas components and dust in the atmosphere, environmental monitoring departments need to use air samplers. With the development of technology, various types of air samplers have emerged. With the requirements of air sampling technology and to obtain effective sampling results, there are also certain requirements for constant temperature and constant flow of air samplers. Therefore, constant temperature and constant flow air samplers have begun to appear on the market, and constant temperature and constant flow has become a well-known standard technology.

[0003] Chinese patent CN203101133U discloses a constant-temperature dual-channel atmospheric sampler that can simultaneously achieve constant temperature function and sampling flow control function, and has the advantages of lightweight structure, simple operation, high degree of intelligence and portability.

[0004] When installing and using existing constant temperature and constant flow atmospheric samplers, the sampling direction is usually fixed or manually adjusted periodically. Fixed installation cannot adapt to dynamic changes in wind direction. When the wind direction changes, the deviation between the sampling direction and the wind direction will persist, resulting in insufficient sample representativeness during long-term sampling. Although manual adjustment can correct the sampling direction to some extent, it requires on-site operation by staff, which not only increases labor costs but also cannot achieve real-time adjustment and still poses a risk of sampling deviation. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the existing technology: fixed installation cannot adapt to dynamic changes in wind direction. When the wind direction changes, the deviation between the sampling direction and the wind direction will persist, resulting in insufficient sample representativeness during long-term sampling. Although manual adjustment can correct the sampling direction to some extent, it requires on-site operation by staff, which not only increases labor costs but also cannot achieve real-time adjustment and still poses a risk of sampling deviation. Therefore, this invention proposes a constant temperature and constant flow intelligent atmospheric sampler.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A constant temperature and constant flow intelligent atmospheric sampler includes a mounting base, on the upper surface of which an annular support rail is fixedly mounted via a support rod. A rotating seat is rotatably mounted on the support rail via multiple sets of sliding components. The sampler body is fixedly mounted on the upper surface of the rotating seat. A guide plate is mounted on the upper surface of the sampler body via an installation assembly. The guide plate is vertically positioned above the sampler body and is parallel to the sampling direction of the sampler body. A tail fin is symmetrically and obliquely fixedly mounted on the end of the guide plate away from the sampling port of the sampler body. Multiple reinforcing ribs are horizontally fixedly mounted between the two tail fins.

[0007] Preferably, the upper and lower surfaces of the support rail are provided with annular rolling grooves. The sliding assembly includes a connecting seat, two rotating shafts and two rollers. The two rotating shafts are horizontally rotatably mounted on the connecting seat, and the two rollers are rotatably mounted on one end of the two rotating shafts respectively. The two rollers roll in the two rolling grooves respectively, and the connecting seat is fixedly mounted on the lower surface of the rotating seat.

[0008] Preferably, the mounting assembly includes a support base and multiple sets of screws and nuts. The upper end of the support base has a slot, and the lower end of the guide plate is inserted into the slot. The side of the support base has multiple insertion holes that are all connected to the slot. The side of the guide plate has multiple limiting holes, which are respectively aligned with the multiple insertion holes. The multiple sets of screws and nuts are respectively inserted into the multiple limiting holes and insertion holes.

[0009] Preferably, a vertical rod is fixedly mounted on the lower surface of the mounting base, and a base is fixedly mounted on the lower end of the vertical rod.

[0010] Preferably, a plurality of anti-slip pads are fixedly installed on the lower surface of the base, and the plurality of anti-slip pads are all made of rubber.

[0011] Preferably, both the air deflector and the tail fin are made of acrylic material, and the air deflector and the tail fin are integrally formed.

[0012] The beneficial effects of this utility model are as follows: When the wind direction changes, the airflow will generate thrust on the deflector and tail fin, thereby causing the sampler body to rotate on the mounting base. This ensures that the sampling direction of the sampler body is always consistent with the wind direction, avoiding the deviation of the sampling area caused by wind direction deviation. The atmospheric samples collected during long-term sampling can truly reflect the air quality of the monitored area, effectively solving the problems of insufficient sample representativeness and lag in manual adjustment in traditional fixed installation methods, while saving the labor cost of manual on-site adjustment.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-2 A constant temperature and constant flow intelligent atmospheric sampler includes a mounting base 1. A ring-shaped support rail 3 is fixedly mounted on the upper surface of the mounting base 1 via a support rod 2. A rotating seat 4 is rotatably mounted on the support rail 3 via multiple sets of sliding components. A sampler body 5 is fixedly mounted on the upper surface of the rotating seat 4. A guide plate 6 is mounted on the upper surface of the sampler body 5 via mounting components. The guide plate 6 is vertically positioned above the sampler body 5 and is parallel to the sampling direction of the sampler body 5. A tail fin 7 is symmetrically and obliquely fixedly mounted at the end of the guide plate 6 away from the sampling port of the sampler body 5. Multiple reinforcing ribs 8 are horizontally fixedly mounted between the two tail fins 7.

[0017] Mounting base 1 provides the basic mounting carrier for the entire sampler, ensuring the stability of each component. Support rod 2 vertically connects mounting base 1 and support rail 3, providing fixed support for support rail 3. The annular support rail 3 provides a 360° annular sliding track for the sliding assembly, ensuring that the rotating seat 4 can freely rotate to adapt to different wind directions. The sliding assembly realizes the rotational connection between the rotating seat 4 and the support rail 3, reducing rotational resistance. The sampler body 5 is fixed on the upper surface of the rotating seat 4, driving the sampler body 5 to rotate synchronously with the sliding assembly, realizing the adjustment of the sampling direction. The sampler body 5 is the core component of atmospheric sampling, possessing constant... The constant temperature and flow function enables precise collection of atmospheric samples. The deflector plate 6 is vertically installed above the sampler body 5 and parallel to the collection direction, guiding the airflow towards the collection port. At the same time, it works with the tail fin plate 7 to sense the wind direction. The tail fin plate 7 is symmetrically tilted and fixed at the end of the deflector plate 6 away from the collection port, forming a force-bearing structure similar to a "weather vane". When the airflow acts on the tail fin plate 7, it generates a horizontal thrust, causing the deflector plate 6 and the sampler body 5 to turn. The reinforcing rib 8 is horizontally fixed between the two tail fin plates 7 to enhance the structural strength of the tail fin plate 7, prevent the tail fin plate 7 from deforming due to strong winds, and ensure the accuracy of wind direction sensing.

[0018] Reference Figures 3-4 The support rail 3 has annular rolling grooves on both its upper and lower surfaces. The sliding assembly includes a connecting seat 9, two rotating shafts 10, and two rollers 11. The two rotating shafts 10 are horizontally rotatably mounted on the connecting seat 9, and the two rollers 11 are rotatably mounted on one end of each of the two rotating shafts 10. The two rollers 11 roll within the two rolling grooves. The connecting seat 9 is fixedly mounted on the lower surface of the rotating seat 4. The rolling grooves on the upper and lower surfaces of the support rail 3 provide limiting and sliding space for the rollers 11, preventing them from detaching from the support rail 3, while ensuring that the rollers 11 only... Rolling along the circular track, the connecting seat 9 is fixed on the lower surface of the rotating seat 4, providing an installation reference for the rotating shaft 10, ensuring that the two rotating shafts 10 are horizontal and symmetrical. The rotating shaft 10 is horizontally rotatably mounted on the connecting seat 9, providing a rotation fulcrum for the roller 11, allowing the roller 11 to roll flexibly. The two rollers 11 roll in the upper and lower rolling grooves respectively, forming a clamping rolling structure for the support rail 3, which reduces the rotational resistance of the rotating seat 4 and ensures that the rotating seat 4 does not deviate or tilt during rotation, ensuring that the sampler body 5 rotates smoothly.

[0019] Reference Figure 5 The mounting components include a support base 12 and multiple sets of screws, nuts and fasteners 13. The upper end of the support base 12 has a slot, and the lower end of the guide plate 6 is inserted into the slot. Multiple insertion holes, all connected to the slot, are opened through the side of the support base 12. Multiple limiting holes are opened on the side of the guide plate 6, and the multiple limiting holes are aligned with the multiple insertion holes. The multiple sets of screws, nuts and fasteners 13 are inserted into the multiple limiting holes and insertion holes respectively.

[0020] The support 12 is fixed on the upper surface of the sampler body 5, providing a mounting carrier for the guide plate 6. The slot is adapted to the lower end of the guide plate 6, which can quickly position the installation position of the guide plate 6, ensuring that the guide plate 6 is vertical and parallel to the sampling direction of the sampler body 5. After the insertion hole is aligned with the limiting hole, the screw and nut fastener 13 is inserted and fixed to securely lock the guide plate 6 on the support 12, preventing the guide plate 6 from loosening under the action of airflow. The design of multiple sets of fasteners can distribute the force on the guide plate 6 and prevent damage caused by excessive force on a single connection point. At the same time, the guide plate 6 can be removed by removing the screw and nut fastener 13, which is convenient for later maintenance or replacement of guide plates 6 of different sizes, improving the compatibility of the equipment.

[0021] Reference Figure 1 A vertical rod 14 is fixedly installed on the lower surface of the mounting base 1. A base 15 is fixedly installed at the lower end of the vertical rod 14. Multiple anti-slip pads 16 are fixedly installed on the lower surface of the base 15. All anti-slip pads 16 are made of rubber. The vertical rod 14 vertically connects the mounting base 1 and the base 15. The base 15 increases the contact area between the equipment and the mounting surface, improves the overall stability of the equipment, and prevents the equipment from tipping over. The rubber anti-slip pads 16 can increase the friction between the base 15 and the mounting surface, prevent the equipment from shifting under the action of outdoor wind, and at the same time buffer the impact force when the equipment is placed, protect the base 15 and the mounting surface, and are compatible with mounting surfaces of different materials.

[0022] Both the deflector 6 and the tail fin 7 are made of acrylic and are integrally molded. Acrylic material combines lightweight and high strength. Lightweight design reduces the thrust required for airflow to push the deflector 6 and tail fin 7, ensuring that the sampler body 5 can be turned even in light winds, thus improving the sensitivity of wind direction sensing. High strength allows it to withstand the influence of complex outdoor environments, preventing component deformation, aging, or damage, and extending its service life. The integral molding structure eliminates the splicing gaps between the deflector 6 and tail fin 7, which not only improves the overall structural strength but also prevents rainwater from seeping in from the splicing points and causing corrosion of internal components. At the same time, it reduces airflow turbulence at the gaps, ensuring accurate wind direction sensing.

[0023] In this invention, the guide plate 6 is vertically installed above the sampler body 5 and parallel to the collection direction, guiding the airflow towards the collection port. Simultaneously, it works with the tail fin 7 to sense the wind direction. The tail fin 7 is symmetrically and tilted, fixed at the end of the guide plate 6 furthest from the collection port, forming a force-bearing structure similar to a "weather vane." When the airflow acts on the tail fin 7, it generates horizontal thrust, causing the guide plate 6 and the sampler body 5 to turn, ensuring that the collection direction of the sampler body 5 always aligns with the wind direction. This avoids sampling area deviation caused by wind direction deviation, and the atmospheric samples collected during long-term sampling can accurately reflect the air quality of the monitored area. This effectively solves the problems of insufficient sample representativeness and delayed manual adjustment in traditional fixed installation methods, while also saving the labor costs of on-site manual adjustments.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
