Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection equipment, in particular to a traffic road air quality analyzer. Background Art

[0002] Traffic road air quality analyzer is a device used to monitor the air quality in the traffic environment. It can continuously monitor a variety of pollutants. Traffic road air quality analyzer plays an important role in urban environmental monitoring. By accurately monitoring pollutants in the traffic environment, it helps environmental protection departments and research institutions understand and control traffic pollution and improve urban air quality. In addition, the deployment and application of these devices also provide the public with a way to understand the quality of the environment they are in, and enhance the public awareness of environmental protection.

[0003] In the utility model patent with patent announcement number CN219891187U, a box cover is provided to facilitate the inspection and cleaning of the interior of the protective box. The sealing ring plays a sealing role and increases the friction between the inner wall of the protective box so that the box cover will not be easily opened. The air inlet pipe is used to introduce outside air into the protective box for analysis of the air quality by the analysis host and the analysis results are displayed on the display screen. The mounting plate facilitates the installation of the air inlet pipe so that the air inlet pipe can be installed separately and is not fixed and cannot be disassembled. The air outlet pipe is used to release the detected air. Although this method can be used for analysis and detection, it also has the problem that the air inlet and outlet are horizontally arranged and exposed to the outside world. Even with the protection of the filter, rainwater will still enter, especially in rainy weather with opposite wind flow, which can easily put the analyzer in a humid environment and cause erosion damage to the circuit system.

[0004] Therefore, it is necessary to provide a traffic road air quality analyzer to solve the above technical problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a traffic road air quality analyzer to solve the problem that the air inlet and outlet are arranged horizontally and exposed to the outside world. Even with the protection of the filter, rainwater will still enter, especially in rainy weather with opposite wind flow, which can easily put the analyzer in a humid environment and cause corrosion damage to the circuit system.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A traffic road air quality analyzer, comprising: a protection box;

The connecting holes are connected to the interior of the protective box. An air intake mechanism is installed in the left mounting groove, and an exhaust mechanism is installed in the right mounting groove. An air intake fan is installed inside the air intake mechanism, and an exhaust fan and a solenoid valve are installed inside the exhaust mechanism. The air intake mechanism and the exhaust mechanism are both mounted to the side of the protective box by bolts.

[0009] In one embodiment, sealing grooves are opened around the bottom surface of the protective box, sealing strips are installed inside the sealing grooves, and a sealing plate is installed on the top surface of the bottom plate. The sealing plate is a rectangular frame structure, and its size is matched with the internal size of the sealing groove.

[0010] In one embodiment, the air intake mechanism is composed of an installation box, a connecting pipe, an air guide plate, and an air inlet. A connecting pipe is installed inside the installation box. The connecting pipe is an L-shaped structure as a whole. The end of the horizontal section of the connecting pipe passes through the connecting hole and extends to the inside of the protective box. The end of the vertical section of the connecting pipe extends to the inside of the air guide plate. An air intake fan is installed inside the vertical section of the connecting pipe. The side of the air guide plate facing the protective box is spaced apart from the outer wall of the protective box, and the air guide plate is provided with an air inlet toward the bottom of the protective box.

[0011] In one embodiment, a slot is provided on the bottom surface of the air inlet, a filter is screwed into the slot, and a distance is left between the filter and the air inlet.

[0012] In one embodiment, a shielding plate is installed on the outer side of the top surface of the installation box, and the shielding plate is a downwardly inclined triangular structure.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The utility model is installed in an embedded installation groove through an air inlet mechanism and an air exhaust mechanism, and the air inlet is arranged toward the outer wall of the protective box to shield the air inlet to prevent rainwater from directly entering the air inlet pipe and corroding the analytical instrument.

[0015] (2) After the protection box and the bottom plate are installed, the sealing plate is tightly abutted against the sealing strip in the sealing groove to improve the overall sealing performance. At the same time, because the maintenance end is located at the bottom, a gap is avoided on the upper part of the protection box, thereby avoiding the problem of rainwater penetration. By setting the bolt connection at the bottom of the filter, there is no need to manually remove the bottom plate to replace and maintain the filter, which improves the maintenance efficiency and convenience. After the air inlet mechanism and the exhaust mechanism are installed, the vertical surface of the shielding plate is abutted against the side top surface of the protection box to form a shielding area for the air inlet mechanism and the exhaust mechanism.
