Description
Technical Field
[0001] The utility model relates to the technical field of atmospheric environment monitoring, in particular to a gridded atmospheric environment monitoring data acquisition device. Background Art
[0002] Atmospheric environment monitoring is the process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. This is the basis for air quality control and reasonable evaluation of air quality. With the development of science and technology, most of the current atmospheric environment monitoring methods use gridded atmospheric monitoring devices, which are an atmospheric environment monitoring technology based on spatial grid division. It sets up dense monitoring points within the city to build a monitoring network covering the entire city, realizing real-time monitoring and data analysis of air quality. This monitoring device not only improves the accuracy and scope of monitoring, but also provides more comprehensive and detailed air quality information, providing strong support for urban environmental management and decision-making.
[0003] In order to ensure the detection accuracy of the atmospheric samplers in the atmospheric environment monitoring data acquisition devices in the prior art, they cannot be directly exposed to rain during use. Therefore, the atmospheric samplers in the atmospheric environment monitoring data acquisition devices are installed inside the corresponding protection boxes. In order for the atmospheric samplers to be able to sample the surrounding atmosphere, a ventilation cavity is opened on the side of the protection box. At the same time, in order to ensure the ventilation smoothness of the ventilation cavity, the ventilation cavity in the prior art is not provided with a corresponding rainproof structure. Therefore, when it rains heavily, external rainwater can easily enter the protection box through the ventilation cavity, causing the atmospheric sampler inside the protection box to become damp and damaged, thereby causing losses to the users, and the practicality is poor.

[0022] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-5 , the utility model provides a technical solution:
[0024] Embodiment 1:
[0025] A grid-based atmospheric environment monitoring data acquisition device comprises a wind direction and anemometer 1, a collection box 2, a support column 5, an online dust monitor 6, a rainfall data collector 7, a ventilation chamber 8 and an atmospheric sampler 9. The online dust monitor 6 is installed on the right side of the upper end face of the collection box 2. The online dust monitor 6 can continuously monitor the dust concentration in the ambient air when working and upload it to an external grid-based atmospheric environment monitoring system. A rainfall data collector 7 is installed in the middle position of the upper end face of the collection box 2. The rainfall data collector 7 can automatically measure and record rainfall process data when working and upload it to an external grid-based atmospheric environment monitoring system. A wind direction and anemometer 1 is installed on the rear side of the upper end face of the rainfall data collector 7. The wind direction and anemometer 1 is installed on the right side of the upper end face of the collection box 2. It can measure the instantaneous wind speed and direction of the surrounding environment and upload them to the external grid atmospheric environment monitoring system. An atmospheric sampler 9 is installed inside the collection box 2. When working, the atmospheric sampler 9 can collect atmospheric pollutants or polluted atmosphere entering the collection box 2, and upload the collected data to the external grid atmospheric environment monitoring system. The wind direction and anemometer 1, the online dust monitor 6, the rainfall data collector 7 and the atmospheric sampler 9 are all connected to the external grid atmospheric environment monitoring system through signal lines. Since the internal detailed structure and working principle of the wind direction and anemometer 1, the online dust monitor 6, the rainfall data collector 7 and the atmospheric sampler 9 are relatively mature technologies in the existing technology, they will not be elaborated here.
[0026] A support column 5 is fixedly connected to the bottom of the collection box 2, and the support column 5 can support and fix the collection box 2. Ventilation cavities 8 are symmetrically opened on the left and right end surfaces of the collection box 2. The ventilation cavity 8 facilitates external air to enter the collection box 2. A protective door panel 21 is installed on the front end surface of the collection box 2, and the protective door panel 21 is a detachable structure. The detachable protective door panel 21 facilitates the staff to inspect and maintain the interior of the collection box 2 at a later time. An internal rain shield component 4 is arranged inside the collection box 2, and the internal rain shield component 4 is used to seal the inner side of the ventilation cavity 8 to block rain. External rain shield components 3 are arranged on both the left and right sides of the interior of the collection box 2, and the external rain shield component 3 is used to seal the outer side of the ventilation cavity 8 to block rain.
[0027] The internal rain shield assembly 4 includes a transparent protective cover 41, a light-sensitive raindrop sensor 42, a connecting plate 43, a programmable logic controller 44, a digital hydraulic cylinder 45 and an internal rain shield 46. A digital hydraulic cylinder 45 is installed on the upper side of the inner wall of the collection box 2. The digital hydraulic cylinder 45 can complete the length vector control at different speeds through the digital pulse signal emitted by the programmable logic controller 44, so as to drive the connecting plate 43 to move up and down. Since the internal detailed structure and working principle of the digital hydraulic cylinder 45 are relatively mature technologies in the prior art, they will not be described in detail here. A connecting plate 43 is installed at the lower end of the hydraulic cylinder 45, and the connecting plate 43 is connected to the internal rain shield 46 by welding. The connecting plate 43 can drive the internal rain shield 46 to move up and down. Internal rain shields 46 are arranged on both sides of the connecting plate 43. The front-to-back length of the internal rain shield 46 is greater than the front-to-back length of the inner wall of the ventilation cavity 8, and the upper and lower lengths of the internal rain shield 46 are greater than the upper and lower lengths of the inner wall of the ventilation cavity 8. Two groups of internal rain shields 46 are arranged, and the specifications of the two groups of internal rain shields 46 are the same. When the two groups of internal rain shields 46 are moved down into place, they can seal the inner side of the ventilation cavity 8 from rain.
[0028] A transparent protective cover 41 is installed on the left side of the upper end surface of the collection box 2. The transparent protective cover 41 is made of tempered glass. The transparent protective cover 41 made of tempered glass not only provides waterproof protection for the light-sensitive raindrop sensor 42, but also facilitates the light-sensitive raindrop sensor 42 to measure the raindrop density on the upper end surface of the transparent protective cover 41 in real time, and transmits the detected data to the programmable logic controller 44 in real time. A light-sensitive raindrop sensor 42 is installed inside the transparent protective cover 41. When working, the light-sensitive raindrop sensor 42 can use the change of light to detect whether it is raining outside the transparent protective cover 41 and the amount of rain. Since the internal detailed structure and working principle of the light-sensitive raindrop sensor 42 are both relatively mature technologies in the prior art , so I will not go into details here. The light-sensitive raindrop sensor 42 is connected to the programmable logic controller 44 through a signal line. The programmable logic controller 44 is installed on the upper side of the inner wall of the collection box 2. The programmable logic controller 44 is connected to the digital hydraulic cylinder 45 through a signal line. The programmable logic controller 44 is connected to the external power supply through a wire. The programmable logic controller 44 stores instructions for performing logical operations, sequential control, arithmetic operations and other operations in its interior and controls the digital hydraulic cylinder 45 to work as required through digital or analog input and output. Since the internal detailed structure and working principle of the programmable logic controller 44 are relatively mature technologies in the prior art, I will not go into details here.
[0029] Embodiment 2:
[0030] On the basis of the first embodiment, in the present embodiment, when the internal rain shield plate 46 moves downward, the internal rain shield plate 46 will drive the active rack 35 to descend together, so that the active rack 35 drives the transmission gear 34 to rotate clockwise, and then the clockwise rotating transmission gear 34 will drive the external rain shield plates 31 on the left and right sides to move upward through the driven teeth 32 to block the rain on the outside of the ventilation cavity 8, thereby further improving the sealing and rain-proofing effect of the ventilation cavity 8.
[0031] The external rain shield assembly 3 includes an external rain shield 31, a driven tooth 32, a support shaft 33, a transmission gear 34 and an active rack 35. The lower end surface of the internal rain shield 46 is provided with an active rack 35, and the active rack 35 is connected to the internal rain shield 46 by welding. The active rack 35 can drive the transmission gear 34 to rotate during the up and down movement. The outer surface of the active rack 35 is sprayed with anti-rust paint, and the anti-rust paint prevents the active rack 35 from being easily rusted during use. The support shafts 33 are symmetrically arranged on the left and right sides of the collection box 2. The support shafts 33 are symmetrically arranged on the left and right sides of the collection box 2. The shaft 33 is connected to the transmission gear 34 by welding. The front and rear ends of the support shaft 33 are both inside the collection box 2. The support shaft 33 enables the transmission gear 34 to rotate. The annular side of the support shaft 33 is provided with a transmission gear 34. The transmission gear 34 is respectively meshed with the active rack 35 and the driven teeth 32. When the transmission gear 34 rotates, it can drive the external rain shield 31 to move up and down through the driven teeth 32. The outer surface of the transmission gear 34 is sprayed with anti-rust paint, and the anti-rust paint prevents the transmission gear 34 from easily rusting during use.
[0032] External rain shields 31 are symmetrically arranged on the left and right sides inside the collection box 2. The front-to-back length of the external rain shield 31 is the same as the front-to-back length of the inner wall of the ventilation chamber 8, and the upper and lower lengths of the external rain shield 31 are greater than the upper and lower lengths of the inner wall of the ventilation chamber 8. The external rain shield 31 can block the outside of the ventilation chamber 8 from rain. A driven tooth 32 is arranged between the transmission gear 34 and the external rain shield 31. The driven tooth 32 is connected to the external rain shield 31 by welding. The driven tooth 32 facilitates the transmission gear 34 to drive the external rain shield 31 to move up and down. The outer surface of the driven tooth 32 is sprayed with anti-rust paint, and the anti-rust paint prevents the driven tooth 32 from easily rusting during use.
[0033] Working principle: During the use of this device, the online dust monitor 6 can continuously monitor the dust concentration in the ambient air and upload it to the external grid-based atmospheric environment monitoring system. The rainfall data collector 7 can automatically measure and record the rainfall process data and upload it to the external grid-based atmospheric environment monitoring system. The wind direction and anemometer 1 can measure the instantaneous wind speed and direction of the surrounding environment and upload it to the external grid-based atmospheric environment monitoring system. The atmospheric sampler 9 can collect atmospheric pollutants or polluted atmosphere entering the collection box 2, and upload the collected data to the external grid-based atmospheric environment monitoring system to monitor the surrounding atmospheric environment. When it rains, raindrops will adhere to the upper end surface of the transparent protective cover 41. At this time, the light-sensitive type The raindrop sensor 42 can detect rain outside the transparent protective cover 41 by using the change of light, and transmit the detected data to the programmable logic controller 44. At this time, the programmable logic controller 44 will receive the transmitted signal and control the digital hydraulic cylinder 45 to extend, so that the digital hydraulic cylinder 45 drives the internal rain shields 46 on the left and right sides to move downward through the connecting plate 43, so that the internal oil shields can block the rain on the inside of the ventilation cavity 8; at the same time, the internal rain shield 46 will drive the active rack 35 to descend together, so that the descending active rack 35 drives the transmission gear 34 to rotate clockwise, and the clockwise rotating transmission gear 34 will drive the external rain shields 31 on the left and right sides to move upward through the driven teeth 32 (refer to Figure 5 ), so that the external rain shield 31 can block the outside of the ventilation cavity 8 from rain, so as to prevent rainwater from entering the collection box 2 through the air inlet cavity on rainy days, causing the atmospheric sampler 9 to be damp and damaged. Similarly, when it is not raining, the light-sensitive raindrop sensor 42 will transmit the detected changes to the programmable logic controller 44, so that the programmable logic controller 44 controls the digital hydraulic cylinder 45 to retract, so that the internal rain shield 46 and the external rain shield 31 can move synchronously in opposite directions to open (reference Figure 3 ), at this time, the external air will enter the collection box 2 through the ventilation cavity 8 again and be collected by the atmospheric sampler 9 for atmospheric pollutants.
