Patented technology solves the waterproof problem of louver box
1. Patented technology background

With the rapid development of society and economy, the continuous expansion of the scale of cities, the intensification of human production and living activities, the increase of industrial and mining enterprise exhaust gas and motor vehicle exhaust emissions, resulting in a continuous atmospheric environment Worsened. At present, the government only obtains the corresponding regional pollutant concentration and its change trend in real time by setting up automatic monitoring points of the atmospheric environment in key cities across the country, and analyzes its impact on air quality in the region under the action of atmospheric circulation. Obviously, this is far from satisfying the research and analysis of environmental protection departments and related agencies on the temporal and spatial distribution of air pollutants and their changing laws.

The main monitoring items of the atmospheric environment automatic monitoring points include sulfur dioxide, nitrogen oxides, ozone, floating and sinking, PM2.5 and other factors. At present, the monitoring requirements for semi-open spaces of the environment are relatively high, and the existing atmospheric monitoring sensors are usually installed in louver boxes to meet the semi-open requirements. However, in actual use, due to special weather such as rain, snow, strong wind, etc., rainwater, dust, etc. will enter the louver box, causing the sensor circuit board to malfunction.

2. Patent content

In order to overcome the shortcomings of the above-mentioned prior art, a louver box for atmospheric environment monitoring is provided. This louver box is equipped with a cavity for installing a sensor current plate. The room can effectively reduce or avoid the erosion of the circuit board components by rain, snow and dust, and improve the service life and reliability of the equipment.

Where is the chamber?

This louver box includes a top louver and a number of sub-louvers installed on top of each other. There is a hole in the middle of the sub-louvers for air to pass through, and there is a connection between the top louver and the uppermost terminal louver. The louver board has a hole in the middle of the connecting louver board. The upper and lower surfaces of the connecting louver board are provided with annular sealing plates. The louver, the sealing plate, and the uppermost sub-louver constitute a cavity for installing the sensor circuit board. See the figure below for details:

3. Patent significance

The utility model of the shutter box adds a connecting louver, and a sealing plate is set on the connecting louver, so that the top louver, sealing plate, The uppermost sub-louver constitutes a sealed chamber for installing the sensor circuit board, which can effectively prevent rain and snow from entering the louver box through the gap between the sub-louver, causing erosion to the circuit board, and improving the overall louver box. The service life and stability of the detection device.

IV. Introduction to the louver box

Advantages:

1. The use of new patented technology, the appearance of an increased connection louver, to prevent rain, snow, strong wind and other bad weather from causing damage to the internal circuit board and sensors , Affect measurement data. The key components are imported components, which are stable and reliable; it has the characteristics of wide measurement range, good linearity, good waterproof performance, convenient use, easy installation, and long transmission distance.

2. The weather shutter box is small in size, light in weight, and has a long service life; it adopts a high-sensitivity probe, the signal is stable, and the accuracy is high;

3, the outside of the shutter box is of high quality The anti-ultraviolet material can effectively block ultraviolet radiation and prevent rapid aging of the equipment.

4. The louver box can integrate noise collection, PM2.5 and PM10, temperature and humidity, atmospheric pressure, and light. It can be installed in the louver box, and the required parameters can also be installed according to customer requirements.

5. The equipment adopts standard ModBus-RTU communication protocol, RS485 signal output, and the maximum communication distance can reach 2000 meters (measured).

(485 wiring instructions)

6. The new patented weather shutter box is widely used in various occasions that need to measure environmental temperature and humidity, noise, air quality, atmospheric pressure, and light.
