Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to a dust detection device for a dusty area. Background Art

[0002] Desertification is a natural (unnatural) phenomenon in which the productivity of large areas of soil decreases or is lost due to factors such as drought, lack of rainfall, vegetation destruction, overgrazing, strong wind erosion, water erosion, and soil salinization. The final result of desertification is mostly desertification. The direct indicator reflecting the intensity of soil wind erosion and sand activity is sand flux. Monitoring of near-ground sand activity is the main content of ground monitoring of soil wind erosion, which mainly monitors wind and sand flows. The monitoring results can provide basic data for soil wind erosion detection and forecasting.

[0003] In the utility model patent with patent announcement number CN219799143U, it is convenient for workers to climb directly by setting up multiple round bars, so that the upper sensor can be replaced and repaired more quickly. When not in use, the round bars can be removed. Through the combination of multiple round bars, a support rod can be formed to support the entire column, thereby improving the stability of the entire column to a certain extent. Although this method can facilitate manual climbing, it is only a temporary solution and the sensor detection method is still in the outside world. The detection method cannot avoid damage to the sensor, so it cannot be used in actual work.

[0004] Therefore, it is necessary to provide a dust detection device in a dusty area 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 dust detection device in a dusty area to solve the problem that although the existing method can facilitate manual climbing, it is only a temporary solution and not a fundamental solution. The detection method of the sensor is still in the outside world, and the detection method cannot avoid damage to the sensor, so it cannot be used in actual work.

An exhaust plate is installed on the side of the detection box away from the air inlet hole, and an exhaust fan is installed on the outside of the exhaust plate. A fine-pore filter is installed at the connection between the exhaust plate and the detection box, and the fine-pore filter is arranged diagonally with the air inlet hole. A detection plate is installed inside the cylindrical structure of the detection box, and the detection plate is located below the fine-pore filter. The middle part of the detection plate is connected to the motor shaft, and a weighing platform is installed on the top surface of the detection plate. The weighing platform is electrically connected to the data storage unit located on the top surface of the mounting frame, and a solar panel is installed on the top surface of the detection box.

[0009] In one embodiment, the exhaust plate is screwed to the detection box, and the fine-pore filter is screwed to the mounting plate via bolts.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0021] like Figure 1-Figure 2 As shown, the utility model provides a dust detection device for a dusty area, comprising: a mounting frame 1, a detection box 2, an air inlet 3, a solar panel 4, an exhaust plate 5, a data storage unit 6, and a detection plate 7;

[0022] like Figure 1-Figure 2 As shown, rods 11 are installed at the four corners of the bottom of the mounting frame 1, and conical nails are installed at the bottom of the rods 11. A detection box 2 is installed in the middle of the mounting frame 1. The upper part of the detection box 2 is a rectangular structure, and the lower part is a cylindrical structure. An air inlet hole 3 is opened on the top left side of the detection box 2, and a plurality of air inlet holes 3 are arranged side by side and spaced apart. An exhaust plate 5 is installed on the side of the detection box 2 away from the air inlet hole 3, and an exhaust fan is installed on the outside of the exhaust plate 5. A fine-pore filter 51 is installed at the connection between the exhaust plate 5 and the detection box 2, and the fine-pore filter 51 is arranged diagonally with the air inlet hole 3. A detection plate 7 is installed inside the cylindrical structure of the detection box 2, and the detection plate 7 is located below the fine-pore filter 51. The middle part of the detection plate 7 is connected to the motor shaft 72. Then, a weighing platform 71 is installed on the top surface of the detection plate 7, and the weighing platform 71 is electrically connected to the data storage unit 6 located on the top surface of the mounting frame 1. A solar panel 4 is installed on the top surface of the detection box 2, and the solar panel 4 is used to power the motor shaft 72, the data storage unit 6, and the weighing platform 71. When working, by starting the exhaust fan at the exhaust plate 5, the external sand-containing gas enters the detection box 2 from the air inlet 3. When passing through the fine-pore filter 51, the sand and dust in the air are blocked by the fine-pore filter 51, and the air is discharged from the exhaust plate 5. The sand falls into the weighing platform 71 of the detection plate 7 below. After recording the weight, the data is transmitted to the data storage unit 6 for manual extraction of the detection data. For example, the air is pumped for five minutes to obtain the corresponding weight of sand, which is converted into the dust content to complete the detection work.

[0023] Preferably, in one embodiment, Figure 1-Figure 3As shown, the exhaust plate 5 is screwed to the detection box 2, and the fine-pore filter 51 is screwed to the mounting plate 53 by bolts 52, so that the fine-pore filter 51 can be quickly disassembled and maintained.

[0024] Preferably, in one embodiment, the outer side surface of the exhaust plate 5 is a tapered narrow opening structure, and a coarse filter is installed inside the outer opening, so as to prevent external debris from entering the exhaust plate 5.

[0025] Preferably, in one embodiment, a guide plate 8 is installed inside the rectangular section of the detection box 2. Two guide plates 8 are arranged opposite to each other. The guide plate 8 is located between the fine-pore filter 51 and the detection plate 7. The purpose is to provide guidance for the sand particles after being blocked so that the sand particles can completely fall into the weighing platform 71 of the detection plate 7.

[0026] Preferably, in one embodiment, a sand discharge port 21 is installed at the bottom of the detection box 2. After the weighing platform 71 completes weighing, the motor shaft 72 drives the detection plate 7 to rotate 360 ​​degrees to discharge the sand from the outside of the detection box 2.

[0027] Working principle of this utility model:

[0028] During operation, by starting the exhaust fan at the exhaust plate 5, the external sand-containing gas enters the detection box 2 from the air inlet 3. When passing through the fine-pore filter 51, the sand and dust in the air are blocked by the fine-pore filter 51, and the air is discharged from the exhaust plate 5. The sand particles fall into the weighing platform 71 of the detection plate 7 below. After recording the weight, the data is transmitted to the data storage unit 6 for manual extraction of the detection data. For example, by exhausting the air for five minutes, the corresponding weight of the sand particles is obtained to convert the dust content, and the detection work can be completed. After the weighing platform 71 completes the weighing, the motor shaft 72 drives the detection plate 7 to rotate 360 ​​degrees to discharge the sand particles from the outside of the detection box 2.
