Description

Technical Field

[0001] The present invention relates to the field of environmental protection detection equipment, and in particular to environmental protection detection equipment and a detection method for highway construction. Background Art

[0002] Currently, commonly used construction dust monitoring equipment is usually an electronic automatic detection device. For example, the patent with application number CN202111350563.X discloses a portable on-site air quality detector for environmental protection engineering construction, and specifically discloses that "the portable on-site air quality detector for environmental protection engineering construction can simplify the operation of the air quality detector by setting an observation window and a movable window, so that the body does not need to be taken out to use the temperature and humidity sensing area and the air inlet that pass through the opening for detection and observation, and the integrity of the air quality detector can also be guaranteed under harsh conditions at the construction site."

[0003] This type of equipment usually has large detection errors. The reason is that there is usually only one detection point on the detection device, and the detection data displayed on the detection device usually depends on the dust density near the detection point, which makes the detection data prone to errors.

[0025] The dust filtering mechanism includes: a filter screen 12, which is located in the air inlet pipe 10; a slider 11, which is fixedly provided at both ends of the filter screen 12, and is slidably connected to the inner wall of the air inlet pipe 10; a spring 13, whose lower end is fixedly connected to the slider 11; a support plate 14, whose upper end is fixedly connected to the limit plate 14, and the support plate 14 is fixedly connected to the air inlet pipe 10.

[0026] The spray mechanism includes a sprayer 26 , which is fixed on the air inlet pipe 10 . The sprayer 26 is connected to an external water source through a hose 17 . The spray end 15 of the sprayer 26 extends into the air inlet pipe 10 and faces the filter 12 .

[0027] It also includes a measuring mechanism, which includes: a measuring rod 20, the top of which is fixedly connected to the bottom surface of the filter screen 12, and a scale 18 is set on the measuring rod 20; an indicating arrow 19, which is fixedly connected to the glass cover 9 and points to the measuring rod 20.

[0028] The air inlet mechanism includes an air inlet pipe 24 . A plurality of air inlet pipes 24 are fixedly provided on the glass cover 9 . The top of the air inlet pipe 24 is fixedly connected to the protective cover 21 via a plurality of support rods 23 .

[0029] Working principle: When in use, start the suction fan 1, and the suction fan 1 absorbs air from the outside through the air inlet pipe 10, the glass cover 9, and the air inlet pipe 24. When the air passes through the filter 12, the dust in the air is trapped on the filter 12, and the sprayer 26 sprays water mist on the filter 12 to make the dust condense to form dirt to block the filter 12. If there is more dust in the air, the more dirt condenses on the filter 12, so that the less air passes through the filter 12, and a negative pressure is generated in the air inlet pipe 10. Under the action of the negative pressure in the air inlet pipe 10, the filter 12 rises.
