[0002] Municipal road engineering is an important part of urban infrastructure construction, involving the planning, design, construction and maintenance of facilities such as roads, bridges, tunnels, drainage systems, lighting, traffic signs and signal lights in the city. Such projects play a crucial role in urban traffic flow, residents' travel convenience, promotion of economic activities and shaping of the overall urban image.

[0003] Dust refers to solid particles suspended in the air. There are many names for dust by habit, such as dust, floating dust, falling dust, soot, etc. The International Organization for Standardization stipulates that solid suspended matter with a particle size less than 75 μm is defined as dust.

[0004] During the construction of municipal road projects, it is necessary to detect the dust in the surrounding environment of the construction site to monitor and control the dust level in the air, ensure the safety of the working environment, protect the health of workers, and comply with environmental regulations.

[0005] When the existing dust detectors are in use, they cannot concentrate and divert the air in the area to be detected around the dust detector, thereby affecting the detection effect of dust in the air. Content of the Utility Model

[0006] Aiming at the above problems, the purpose of the utility model is to provide a dust detector to solve the problem that the air in the area to be detected cannot be concentrated and diverted around the dust detector, thereby affecting the detection effect of dust in the air. Through the setting of the dust inlet, the air containing dust at the construction site can enter the dust collection cover, and then the air is concentrated and diverted into the detection box through the dust collection cover for dust detection.

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows: A dust detector, comprising a box body assembly, a detection assembly, and a collection assembly. The box body assembly includes a rectangular box body and a box door. The detection assembly includes a mounting plate. The collection assembly includes a collection box and an exhaust fan. One end of the outer wall of the rectangular box body is connected with an operation box. Inside the operation box, a display screen and an operation panel are provided.

At the lower end of the dust collection cover, a first conveying pipe is connected. Inside the rectangular box body, a detection box is provided. Inside the detection box, a second conveying pipe is provided. Inside the detection box, a dust detector is provided. Inside the wall of the collection box, a first diversion plate is connected. Below the first diversion plate, a second diversion plate is provided. On the inner wall of the collection box, guide rails are symmetrically connected. Inside the guide rails, a collection box is slidably connected. Inside the collection box, a collection grid is provided.

[0008] The beneficial effect of the present utility model is as follows: Through the setting of the dust inlet, the air containing dust at the construction site can enter the dust collection cover, and then the air is centrally diverted into the detection box through the dust collection cover for dust detection.

[0009] For the convenience of maintaining the dust detector inside the detection box:

[0010] As a further improvement of the above technical solution: Inside the operation box at the end far from the rectangular box body, a box door is rotatably connected. At the lower end of the rectangular box body, universal wheels are connected through brackets. At the front wall of the rectangular box body, a box door is rotatably connected through a hinge.

Through the connection of the collection box with a box door, it is used to take out the collection box after opening.

[0012] For the air containing dust at the construction site to enter the detection box through the dust inlet and be detected:

[0013] As a further improvement of the above technical solution: The mounting plate is installed on the top of the rectangular box body through a support frame. The outer ring of the dust inlet is provided with an external thread, and the inner wall of the sealing cover is provided with an internal thread.

[0014] The beneficial effect of this improvement is as follows: After the device is pushed to the predetermined detection position, the sealing cover is opened, and then the air containing dust at the construction site enters the detection box through the dust inlet and is detected.

[0015] For the air to be centrally diverted into the detection box through the dust collection cover for dust detection:

[0016] As a further improvement of the above technical solution: One end of the first conveying pipe away from the dust hood penetrates through the top wall of the detection box and extends to the inside of the detection box, and one end of the dust hood away from the first conveying pipe extends to communicate with the dust inlet.

[0017] The beneficial effect of this improvement is that through the setting of the dust inlet, the air containing dust at the construction site is introduced into the dust hood, and then the air is concentrated and guided into the detection box through the dust hood for dust detection.

[0018] In order for the dust detector to calculate the dust concentration and transmit it to the display screen for display:

[0019] As a further improvement of the above technical solution: The dust detector is a laser dust detector, the dust detector is electrically connected to the operation panel, and the dust detector is electrically connected to the display screen.

[0020] The beneficial effect of this improvement is that the operation of the dust detector is started through the operation panel. The dust detector works and emits laser light. When the laser beam passes through the air containing dust, the dust particles cause the light to scatter. The intensity and pattern of the scattered light depend on the size, quantity, and optical properties of the dust particles. The optical sensor inside the dust detector captures this scattered light and converts it into an electrical signal. By analyzing these signals, the dust detector calculates the dust concentration and transmits it to the display screen for display.

The collection box is slidably connected to the inner wall of the collection box through a guide rail. The lower end of the second conveying pipe penetrates through the top wall of the collection box and extends to the inside of the collection box.

[0023] The beneficial effect of this improvement is that through the setting of the second conveying pipe, it is used to convey the air that has completed detection in the detection box into the collection box and discharge it through the exhaust pipe.

[0025] As a further improvement of the above technical solution: There are two first guide plates in total and they are symmetrically connected to the inner wall of the collection box. One ends of the two second guide plates away from each other are connected to the inner wall of the collection box.

[0026] The beneficial effects of this improvement are as follows: Under the action of the exhaust fan, air flows into the collection box through the second delivery pipe. Then, the first deflector and the second deflector gradually decelerate the incoming air, thereby ensuring the collection of dust in the air by decelerating the air.

[0028] As a further improvement of the above technical solution: The exhaust fan is installed on the inner wall of the bottom surface of the collection box. The exhaust fan is electrically connected to the operation panel. An exhaust pipe is provided inside the collection box. The lower end of the exhaust pipe penetrates the bottom wall of the collection box and the bottom wall of the rectangular box and extends to the outside of the rectangular box.

[0029] The beneficial effects of this improvement are as follows: After the detection of dust is completed by the dust detector, the operation of the exhaust fan is started.
