[0024] Example

[0025] like Figure 1-3 As shown, an atmospheric pollution gas detection device includes an upper plate 1 and an elastic pushing device 2. The elastic pushing devices 2 are fixedly connected to both sides of the upper end of the upper plate 1. The elastic pushing devices 2 at both ends are respectively connected to the first protective cover 3 and the second protective cover 4. A gas detection device 9 is fixedly installed on the upper end of the upper plate 1. The first protective cover 3 and the second protective cover 4 can be combined to provide closed protection for the gas detection device 9.

[0026] Among them, the elastic pushing device 2 includes a sleeve 201 and a push rod 202. The sleeve 201 is fixed to the upper surface of the upper plate 1. The push rod 202 is slidably installed on the inner wall of the sleeve 201. A spring 203 is installed between the sleeve 201 and the push rod 202. Through the telescopic effect of the spring 203, the push rod 202 moves horizontally, thereby realizing the extension or retraction of the first protective cover 3 and the second protective cover 4.

[0027] Among them, the outer walls of one side of the first protective cover 3 and the second protective cover 4 are fixed with hanging ears 10, and a pull rope 5 is tied to the hanging ears 10. H-shaped rods 6 are fixed on both sides of the upper plate 1. The pull rope 5 passes around the H-shaped rod 6 and is connected to a winding wheel 11 located at the lower end of the upper plate 1. A motor 12 is fixedly installed on the bottom wall of the upper plate 1, and the power output end of the motor 12 is connected to the power input end of the winding wheel 11; the winding wheel 11 is rotated by the drive of the motor 12 (the motor 12 is specifically a stepping motor that can be rotated forward and reverse), and then the pull rope 5 is retracted and released, thereby realizing the opening of the first protective cover 3 and the second protective cover 4.

[0028] The bottom end of the upper plate 1 is fixedly connected to a base frame 7, and a roller 8 is installed at the bottom end of the base frame 7; the design of the base frame 7 can facilitate the movement of the equipment, and the roller 8 enables the equipment to be flexibly moved to the area that needs to be inspected.

[0029] It should be noted that the utility model is an atmospheric pollution gas detection device. When working, the upper plate 1 is used as the main body of the device, and the upper ends of the upper plate 1 are fixedly connected with elastic extension devices 2 on both sides. Through the expansion and contraction of the spring 203, the push rod 202 is moved horizontally, thereby realizing the extension or retraction of the first protective cover 3 and the second protective cover 4. The first protective cover 3 and the second protective cover 4 are arranged at the upper end of the upper plate 1, and the gas detection device 9 can be closed and protected when combined. The winding wheel 11 is driven by the motor 12 (the motor 12 is specifically a stepping motor that can rotate forward and backward), and then the pull rope 5 is retracted to realize the opening of the first protective cover 3 and the second protective cover 4. After the first protective cover 3 and the second protective cover 4 are opened, the gas detection device 9 will be exposed to the environment. Then, the gas detection device 9 generates corresponding detection data by detecting atmospheric pollutants in the environment. After the detection is completed, the winding wheel 11 is reversed, and the elastic extension device 2 is contracted downward under the action of the spring 203, so that the first protective cover 3 and the second protective cover 4 are closed, and the gas detection device 9 is protected from being eroded by polluted gas. The design of the base frame 7 facilitates the movement of the device, and the rollers 8 enable the device to be flexibly moved to an area that requires inspection.
