Description

Technical Field

[0001] This utility model relates to the field of atmospheric detection technology, and in particular to an atmospheric pollutant detection device with protective function. Background Technology

[0002] An air pollution detection device is an instrument used to monitor the types, concentrations, and distribution of pollutants in the air in real time or periodically, and to provide data support for assessing air quality. Its core function is to perform qualitative and quantitative analysis of pollutants in the atmosphere through physical, chemical, or biological detection technologies, providing crucial data for environmental management, scientific research, and public health protection.

[0003] Regarding the aforementioned technologies, the inventors discovered that when monitoring the atmosphere, air pollutant detection devices are often exposed to the external environment. In strong winds or dusty weather, strong winds can easily blow foreign objects up and impact the air pollutant detection devices, causing damage. Alternatively, in dusty weather, dust particles in the air can easily enter the interior of the air pollutant detection devices, damaging the internal components and shortening their service life. Therefore, it is necessary to design an air pollutant detection device with protective functions. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an atmospheric pollutant detection device with protective function, which reduces the probability of damage to the atmospheric detection device caused by strong winds and sandstorms, and extends its service life.

[0005] To solve the above-mentioned technical problems, the present invention provides a protective atmospheric pollutant detection device, comprising: a square hollow column and an atmospheric pollutant detector detachably connected to its top; a square flange is fitted to the lower end of the square hollow column; a circular top plate is provided above the atmospheric pollutant detector; a plurality of circular rods are connected in a rectangular array on the lower plane of the circular top plate; the lower ends of the circular rods are connected to the square flange; a plurality of arc-shaped plates are connected in a circular array on the lower plane of the circular top plate; an arc-shaped plate is provided between adjacent arc-shaped plates; linear guides are provided between the two sides of the arc-shaped plate and the corresponding arc-shaped plate; a circular frame plate is fitted to the outer side of the square hollow column; the circular frame plate is connected to the lower end of the arc-shaped plate; the circular rods pass through the circular frame plate and the two are slidably connected; and a driving mechanism for driving the arc-shaped plate to move up and down is also included.

[0006] By adopting the above technical solution, the air pollutant detection device is placed in the external environment. The flowing air comes into contact with the air pollutant detector through the gap between the adjacent arc-shaped plates. The air pollutant detector detects the pollutants in the air and obtains detection data. When encountering strong winds or sandstorms, the operating drive mechanism moves the arc-shaped plate upward and connects with the circular top plate. The arc-shaped plates form a circular protective plate to protect the air pollutant detector, preventing foreign objects blown by strong winds from impacting the air pollutant detector and preventing sand and dust from entering the inner cavity of the air pollutant detector. This protects the air pollutant detector, reduces the probability of damage to the air detection device caused by strong winds and sandstorms, and extends its service life.

[0007] In a preferred embodiment, the present invention can be further configured such that: the linear guide includes grooves disposed on both sides of the arc-shaped plate, a guide slider is slidably connected in the groove, and the guide slider is connected to the side of the arc-shaped plate.

[0008] By adopting the above technical solution, the guide slider slides in the groove, thereby guiding the arc plate two to move up and down, which enhances the stability of the arc plate two when it moves.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the four sides of the square hollow column are respectively provided with rectangular holes; the driving mechanism includes a square movable seat, the four sides of the square movable seat are respectively connected to connecting blocks, the connecting blocks pass through the rectangular holes and are connected to the circular frame plate; it also includes a square mounting plate and an electric push rod; the square mounting plate is fixed to the inner side of the square hollow column; and the extended end of the electric push rod is connected to the square movable seat.

[0010] By adopting the above technical solution, the telescopic rod of the electric push rod extends and retracts, thereby driving the square moving seat to move up and down. The square moving seat drives the circular frame plate to move up and down through the connecting block. The circular frame plate drives the arc plate to move up and down. The structure is simple and easy to install.

[0011] In a preferred embodiment, the present invention can be further configured such that the arc length of the second arc plate is twice the arc length of the first arc plate.

[0012] By adopting the above technical solution, sufficient space is left between adjacent curved plates for air flow, which facilitates the detection of air pollutants by the air pollutant detector.

[0013] In a preferred embodiment, the present invention can be further configured such that: a square rod is provided below the square hollow column, and a square flange II is fitted onto the upper outer surface of the square rod, and the square flange II is connected to the arc-shaped plate I by bolts.

[0014] By adopting the above technical solution and setting up a square rod, the air pollutant detector has a certain height, which facilitates the detection of pollutants in flowing air.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the circular frame plate includes a circular plate body, the circular plate body is provided with a square hole, the square hollow column is inserted through the square hole, the circular plate body is provided with a number of circular holes equal to the number of circular rods, the circular rods pass through the circular holes and the two are slidably connected.

[0016] By adopting the above technical solution, and by setting a square hole on the circular plate, it is easy for the circular plate to be fitted onto the outside of the square hollow column, and the circular plate can move up and down under the action of external force.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] The operation of the drive mechanism moves the second arc-shaped plate upward and connects with the circular top plate. The first arc-shaped plate and the second arc-shaped plate form a circular protective plate to protect the air pollutant detector, reducing the probability of damage to the air detection device caused by strong winds and dust, and extending its service life.

The square movable seat 81 drives the circular frame plate 70 to move up and down through the connecting blocks 82. The circular frame plate 70 drives the arc plate 12 to move up and down. The structure is simple and easy to install.

[0032] The linear guide 60 includes a groove 61 provided on the side of the arc plate 12, and a guide slider 62 is slidably connected in the groove 61.

[0033] The arc length of the second arc plate 12 is twice the arc length of the first arc plate 11; there is enough space between adjacent arc plates 11 for air flow, which facilitates the detection of pollutants in the air by the air pollutant detector 2.

[0034] A square rod 14 is provided below the square hollow column 1. A square flange 2 15 is fitted onto the upper outer surface of the square rod 14.

The flowing air comes into contact with the air pollutant detector 2 through the gap between the adjacent arc-shaped plates 11. The air pollutant detector 2 detects the pollutants in the air and obtains the detection data. When encountering strong winds or sandstorms, the operating drive mechanism 80 operates to drive the arc-shaped plate 12 to move upward and abut against the circular top plate 4.

This protects the air pollutant detector 2, reduces the probability of damage to the air detection device caused by strong winds and sandstorms, and extends its service life.
