Description

Technical Field

[0001] The utility model relates to the field of sampling equipment, in particular to an air pollution monitoring sampling equipment. Background Technique

[0002] Air pollution monitoring refers to the process of measuring the types and concentrations of pollutants in the atmosphere and observing their spatial and temporal distributions and variation laws. The purpose of air pollution monitoring is to identify the polluting substances in the atmosphere, master their distribution and diffusion laws, and monitor the emissions and control situations of air pollution sources.

[0003] An air pollution monitoring device samples the surrounding environment in real time through externally connected wind direction sensors, wind speed sensors, particulate matter samplers, etc. These external devices are in contact with the air. At the same time, the collected data is transmitted into the air pollution monitoring device chassis through a data cable, which facilitates the device chassis to uniformly record and analyze the data. For household users, a portable monitor can be selected; for industrial users, more professional equipment may be required.

[0004] When using the sampling equipment, the equipment should be calibrated regularly to ensure the accuracy of the data. By monitoring and analyzing the data, measures can be taken to improve air quality, such as ventilation, air purification, etc. However, the traditional equipment is fixed by screws. When sampling data in different environments, different external devices are required. This method is inconvenient for replacing the equipment later, thus reducing the practicability of the equipment. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an air pollution monitoring sampling equipment to solve the technical problems mentioned in the above background technique.

And a connecting rod is fixedly connected to the outer wall of the driven gear. And the other end of the connecting rod is fixedly connected to a guiding plate. A guiding column is slidably installed in the guiding plate. And a slider is fixedly installed on the guiding column. A support column is fixedly installed on the outer wall of the base. And a guiding groove corresponding to the guiding column is formed in the guiding plate. A driving gear is fixedly installed at the end of the rotating cylinder.

At this time, the user rotates the rotating cylinder, driving the driving gear to rotate, and simultaneously driving the surrounding driven gears to rotate, thereby driving the connecting rod, and finally realizing the rotation of the guiding plate, so that the slider can smoothly slide out of the support column. At this time, the slider can limit the support column, so that the sampling device is fixed on the air pollution monitoring equipment. By restricting the gears, the practicability of the sampling device is ensured.

[0008] Further, the cross-section of the rotating cylinder is designed as a rectangular structure, and the inner wall of the rotating cylinder is in contact with the outer wall of the sampling equipment.

[0009] By adopting the above technical solution, it is ensured that the user can smoothly rotate the rotating cylinder.

[0010] Further, multiple groups of driven gears are symmetrically arranged on the outer wall of the base, and the driven gears and the driving gear are located on the same side of the base.

[0011] By adopting the above technical solution, it is ensured that the user can better rotate multiple groups of driven gears through the driving gear.

[0012] Further, the connecting rod is rotatably connected inside the support column, and a chute corresponding to the slider is provided inside the support column.

[0013] By adopting the above technical solution, it is ensured that the user can smoothly guide the slider out of the support column through the connecting rod.

[0014] Further, multiple groups of guiding columns are arranged inside the guiding plate, and the length of the slider is less than the radius of the guiding plate.

[0016] Further, the support column is located on the other side of the base, and multiple groups of support columns are arranged in a counter-supporting manner on the outer wall of the base.

[0017] By adopting the above technical solution, it is ensured that the sampling equipment is stable on the support frame.

[0018] Further, multiple groups of guiding grooves are provided inside the guiding plate, and the length of the guiding grooves is less than the radius of the guiding plate.

[0019] By adopting the above technical solution, it is ensured that the guiding column will not slide out of the guiding plate when the guiding plate is rotated.

[0020] Further, the driving gear and the driven gear are fitted together, and the driving gear is located at the center of the base.

[0021] By adopting the above technical solution, it is ensured that the driving gear can drive multiple groups of driven gears.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a support column, a guide groove, a slider and a gear set, so that the user can be guided by the support column when installing the sampling device, and the user can conveniently place the sampling device on the air pollution monitoring equipment.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] An air pollution monitoring sampling device, such as Figure 1 - Figure 7 shown, includes a support frame 1, a sampling device 2 and a base 3. A rotating cylinder 4 is rotatably connected to the outer wall of the sampling device 2. A driven gear 5 is rotatably connected to the outer wall of the base 3. A connecting rod 6 is fixedly connected to the outer wall of the driven gear 5. The other end of the connecting rod 6 is fixedly connected to a guide plate 7. The driven gear 5 drives the connecting rod 6 fixedly connected to its outer wall to start rotating. At this time, the guide plate 7 fixedly connected to the other end of the connecting rod 6 starts to rotate. A guide post 8 is slidably installed in the guide plate 7. A slider 9 is fixedly installed on the guide post 8. A support post 10 is fixedly installed on the outer wall of the base 3. A guide groove 11 corresponding to the guide post 8 is opened in the guide plate 7. The guide post 8 drives the slider 9 fixedly connected to its outer wall to slide in the chute provided at the end of the support post 10 until the guide post 8 slides to the other end of the guide groove 11. A driving gear 12 is fixedly installed at the end of the rotating cylinder 4. A locking block 13 corresponding to the driving gear 12 is slidably installed on the outer wall of the base 3. Move the locking block 13 slidably connected to the outer wall of the base 3 to release the restriction on the driving gear 12. Drive the driving gear 12 fixedly connected to the end by rotating the rotating cylinder 4.

[0035] Please refer to Figure 4 , the cross-section of the rotating cylinder 4 is designed as a rectangular structure. The user rotates the rotating cylinder 4 to make the rotating cylinder 4 rotate on the outer wall of the sampling device 2, and the inner walls of the rotating cylinder 4 are all in contact with the outer wall of the sampling device 2 to ensure that the user can smoothly rotate the rotating cylinder 4.

[0036] Please refer to Figure 4 , multiple groups of driven gears 5 are symmetrically arranged on the outer wall of the base 3, and the driven gears 5 and the driving gear 12 are located on the same side of the base 3. By rotating the driving gear 12, the driven gears 5 are driven to rotate, so that multiple groups of driven gears 5 rotate simultaneously driven by the driving gear 12 to ensure that the user can better rotate multiple groups of driven gears 5 through the driving gear 12.

[0037] Please refer to Figure 2 - Figure 6 , the connecting rod 6 is rotatably connected in the support post 10. The rotation of the driven gear 5 drives the connecting rod 6 to rotate in the support post 10. A chute corresponding to the slider 9 is opened in the support post 10. Through the setting of the chute, the slider 9 can smoothly slide in the support post 10 to ensure that the user can smoothly guide the slider 9 outside the support post 10 through the connecting rod 6.

[0038] Please refer to Figure 3 - Figure 6 , multiple groups of guide posts 8 are arranged in the guide plate 7. The rotation of the guide plate 7 drives the guide posts 8 to slide in the guide plate 7. The length of the slider 9 is less than the radius of the guide plate 7. Through the movement of the slider 9, the slider can be smoothly moved into the support post to ensure that the slider 9 can smoothly enter the support post 10.

[0039] Please refer to Figure 2 , the support column 10 is located on the other side of the base 3. Through the guidance of the support column 10, the sampling device 2 can be smoothly installed on the support frame 1. Moreover, multiple groups of support columns 10 are arranged in a counter-bracing manner on the outer wall of the base 3. Through the arrangement of multiple groups of support columns 10, the sampling device 2 is more stably installed on the support frame 1, ensuring that the sampling device 2 is stable on the support frame 1.

[0040] Please refer to Figure 6 , multiple groups of guiding grooves 11 are provided in the guiding plate 7. Through the arrangement of the guiding grooves 11, when the user rotates the guiding plate 7, the slider 9 on the outer wall of the guiding column 8 is moved through the guiding grooves 11, and the length of the guiding grooves 11 is less than the radius of the guiding plate 7, ensuring that the guiding column 8 will not slide out of the guiding plate 7 when the guiding plate 7 is rotated.

[0041] Please refer to Figure 4 , the driving gear 12 meshes with the driven gear 5. Through the rotation of the driving gear 12, multiple groups of driven gears 5 are smoothly driven to rotate, and the driving gear 12 is located at the center of the base 3, ensuring that the driving gear 12 can drive multiple groups of driven gears 5.

[0042] The working principle of the present utility model is as follows: When the user needs to install the sampling device 2 on the support frame 1, first move the lock block 13 slidably connected to the outer wall of the base 3 to release the restriction on the driving gear 12. Drive the driving gear 12 fixedly connected to the end by rotating the rotating cylinder 4, and the driving gear 12 starts to rotate. At the same time, the driving gear 12 drives the driven gear 5 to start rotating, so that the driven gear 5 drives the connecting rod 6 fixedly connected to the outer wall to start rotating. At this time, the guiding plate 7 fixedly connected to the other end of the connecting rod 6 starts to rotate. Due to the fixed connection between the support column 10 and the base 3, under the restriction of the support column 10, the guiding plate 7 drives the guiding column 8 to slide in the guiding groove 11. At the same time, the guiding column 8 drives the slider 9 fixedly connected to the outer wall to slide in the sliding groove provided at the end of the support column 10 until the guiding column 8 slides to the other end of the guiding groove 11. At this time, the slider 9 completely slides out of the support column 10. At this time, the user stops rotating the rotating cylinder 4, and at the same time, the driving gear 12 is limited by the lock block 13 provided on the outer wall of the base 3, making the driving gear 12 unable to rotate. At this time, the installation of the sampling device 2 is completed;

[0043] When the user needs to remove the sampling device 2, move the lock block 13 slidably connected to the outer wall of the base 3 to release the restriction on the driving gear 12. At the same time, drive the rotation of the driving gear 12 through the rotating cylinder 4, so that the driving gear 12 drives the driven gear 5 to be linked at the same time, and further makes the connecting rod 6 drive the guiding plate 7 to rotate. Under the restriction of the support column 10, the slider 9 starts to contract into the support column 10. Finally, the slider 9 contracts into the support column 10. At this time, the user can move the sampling device 2 to realize the removal of the sampling device 2.

[0044] Although embodiments of the present utility model have been shown and described, the specific embodiments are only interpretations of the present utility model and are not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
