Description

Technical Field

[0001] This utility model relates to the technical field of air quality monitoring equipment, specifically to an outdoor online air quality monitoring device. Background Technology

[0002] TVOC is the overall composition of volatile organic compounds (VOCs). It exists in the air at room temperature in the form of evaporation. It has an irritating or distinctive odor and can affect the skin and mucous membranes, causing acute damage to the human body. The World Health Organization, the U.S. National Academy of Sciences, and other institutions have consistently emphasized that TVOC is an important type of air pollutant. TVOC in ambient air can not only directly harm human health, but also interact with each other to cause photochemical pollution. Its adverse effects on human health and the environment have received widespread attention. Currently, monitoring systems are commonly used to monitor outdoor air quality to ensure that air pollution in the production environment is controllable.

[0003] Existing air quality monitoring equipment mainly consists of an equipment cabinet, a dehumidification and filtration system, a PID sensor, and a condensation system. The dehumidification and filtration system ensures the reliable operation of the PID sensor. Combined with the filter tube and dehumidification filter, multiple filtration measures are taken to effectively improve the accuracy of the data. The condenser tube and fan are designed to significantly improve the cooling effect. Together with the PID sensor, PID photoionization detection is performed to ensure effective monitoring of TVOC in the air.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned outdoor air quality online monitoring equipment requires a cabinet structure to house and protect the internal equipment when monitoring air pollution. Since it is used in an outdoor environment, a single shell structure is insufficient to provide adequate protection for the internal filtration system, condensation system, and sensors. When subjected to bumps or localized impacts, the cabinet is prone to deformation, which can damage the internal equipment, affect its use, and pose safety hazards. Therefore, an outdoor air quality online monitoring device is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an outdoor air quality online monitoring device. It forms an internal double-cavity structure by connecting an inner cavity within the outer shell frame, which reduces the impact of external impacts. In addition, it can be used with rubber piles connected to the outer walls of the inner shell frame to reduce the transmission of vibration and impact forces to the internal hardware. With the help of vibration sensors, it can trigger alarms in a timely manner, thereby improving the safety performance of this device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an outdoor air quality online monitoring device, comprising a housing body, an internal monitoring component mounted inside the housing body, the internal monitoring component comprising an inner cavity, and an inner frame mounted inside the inner cavity, a PID monitoring module fixed at the top of the inner frame, and a filtration system and a condensation module sequentially fixed at the bottom of the PID monitoring module, internal ventilation slots opened on both outer walls of the inner frame, and an alarm light connected to the top of the inner frame, and rubber stakes and vibration sensors fixed on all four outer walls of the inner frame.

[0008] Preferably, the inner shell frame is connected to the perimeter of the inner cavity by rubber posts on the outer walls, and the rubber posts are made of rubber.

[0009] Preferably, the vibration sensor is fixed to the center of the outer wall around the inner shell frame, and the vibration sensor is electrically connected to the PID monitoring module.

[0010] Preferably, the alarm light is electrically connected to the PID monitoring module, and the PID monitoring module, the filtration system, and the condensation module are fixedly connected to the inner shell frame.

[0011] Preferably, the PID monitoring module further includes a PCB board, on which a PID sensor and a microcontroller are soldered.

[0012] Preferably, the outer shell body includes an outer shell frame, and a door is fastened to the front end of the outer shell frame. A latch is fixed to one side of the door. Support seats are fixed around the bottom of the outer shell frame, and external ventilation slots are opened on both sides of the bottom of the outer shell frame.

[0013] Preferably, the external ventilation slot is connected to the interior of the outer casing frame, and the support bases are equidistantly distributed around the bottom of the outer casing frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses an inner cavity opened inside the outer shell frame to connect to the inner shell frame, forming an internal double-cavity structure, which reduces the impact of external impacts. It can also work with rubber piles connected to the outer walls around the inner shell frame to reduce the transmission of vibration and impact forces to the internally mounted hardware, thereby providing buffer protection. At the same time, when affected by external forces, the vibration sensor mounted in the center of the outer wall can detect the vibration from multiple directions and trigger an alarm in time, allowing nearby personnel to check, thereby improving the safety performance and long-term stable operation of this equipment.

[0016] 2. This outdoor air quality online monitoring device can be easily mounted or fixed with fasteners using the mounting plates distributed on the upper and lower parts of the outer frame. The support base at the bottom also allows for easy placement of the device. The external ventilation slots on both sides can maintain internal gas circulation with the built-in monitoring components, assisting in the normal monitoring process.

[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

Detailed Implementation

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4An outdoor air quality online monitoring device according to this embodiment includes a housing body 1, with an internal monitoring component 2 mounted inside the housing body 1. The housing body 1 includes a housing frame 101, and a door 102 is fastened to the front end of the housing frame 101. A latch 103 is fixed on one side of the door 102. Support seats 104 are fixed around the bottom of the housing frame 101, and external ventilation slots 105 are opened on both sides of the bottom of the housing frame 101.

[0025] like Figure 1-4 As shown, the outdoor air quality online monitoring device of this utility model has a similar structure to existing outdoor air quality online monitoring devices. The main improvement of this utility model is that the inner cavity 201 opened inside the outer shell frame 101 connects to the inner shell frame 202 to form an internal double-cavity structure, reducing the impact of external impacts. It can also work with the rubber piles 208 connected to the outer walls of the inner shell frame 202 to reduce the vibration and impact force transmission to the internally mounted hardware. With the vibration sensor 209, the alarm can be triggered in time, thereby improving the safety performance of this device. The filtration system 204 and the condensation module 205 in this utility model are existing technologies. When using this outdoor air quality online monitoring device, the filtration system 204 and the condensation module 205 can be improved through the outer shell frame 101. The internally mounted monitoring component 2 is provided with external protection. Mounting plates are fixed at the top and bottom of the housing frame 101, allowing the device to be mounted on walls or other surfaces. Alternatively, the housing frame 101 can be placed directly on the bottom support 104. External air vents 105 on both sides allow external air to flow in while maintaining internal airflow and ensuring the monitoring process. The mounting plates distributed at the top and bottom of the housing frame 101 facilitate mounting or securing the device with fasteners. The bottom support 104 also allows for direct placement of the device. The external air vents 105 on both sides ensure airflow between the internally mounted monitoring component 2 and the monitoring process.

[0026] like Figure 2-4As shown, the built-in monitoring component 2 includes an inner cavity 201, and an inner shell frame 202 is mounted inside the inner cavity 201. A PID monitoring module 203 is fixed to the top of the inner shell frame 202, and a filtration system 204 and a condenser module 205 are sequentially fixed to the bottom of the PID monitoring module 203. Internal ventilation slots 206 are provided on both sides of the outer wall of the inner shell frame 202, and an alarm light 207 is connected to the top of the inner shell frame 202. Rubber posts 208 and vibration sensors 209 are fixed to the four outer walls of the inner shell frame 202. During the application of the monitoring device, the filtration system 204 ensures that the PID sensor inside the PID monitoring module 203 maintains reliable operation. Combined with the filter media tube and filter mounted inside the filtration system 204, multiple filtration measures are taken to improve the accuracy of the data from the PID monitoring module 203. The condenser module 205 maintains the cooling effect of the internal equipment, ensuring stable operation. When the equipment is subjected to external impact... When impacted or bumped, the impact force applied to the outer shell 101 of the equipment is buffered by the gap between the outer shell 101 and the inner shell 202, and further buffered by the rubber piles 208 at the connection. When the impact force is too large, it will trigger the vibration sensor 209 at the center. The onboard microcontroller built into the PID monitoring module 203 will determine the pressure and vibration, and thus provide a warning in conjunction with the alarm light 207. The equipment is connected to the inner shell 202 through the inner cavity 201 opened in the outer shell 101, forming an internal double cavity structure, which reduces the impact of external impact. It can also work with the rubber piles 208 connected to the outer walls of the inner shell 202 to reduce the vibration and impact force transmission to the internal hardware, thus providing buffer protection. At the same time, when affected by external forces, the vibration sensor 209 mounted at the center of the outer wall can detect in multiple directions and trigger an alarm in time, prompting nearby personnel to check, thereby improving the safety performance and long-term stable operation of the equipment.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
