Technical Field

[0001] The utility model belongs to the technical field of flue gas monitoring, and in particular relates to an environmental monitoring device for flue gas monitoring. Background Art

[0002] The flue gas tester uses the Pitot tube isokinetic sampling weight method to capture particulate matter in the pipeline, and uses the constant potential electrolysis method to qualitatively and quantitatively determine harmful gases. It can be used by environmental protection, health, labor, safety supervision, military, scientific research, education and other departments to determine the emission concentration / total amount of smoke (gas) from various boilers and furnaces and the dust removal and desulfurization efficiency of equipment. It can measure flue gas dynamic pressure, flue gas static pressure, pressure before the flow meter, temperature before the flow meter, flue gas temperature, moisture content, O2, SO2, CO, NO, NO2, H2S, CO2, isokinetic suction flow rate, etc.

Two electric push rods are fixedly connected to the bottom of the box body, and the push rods of the two electric push rods are fixedly connected to the fixing column. One side of the fixing column is fixedly connected to two connecting rods, and one end of the two connecting rods away from the fixing column is fixedly connected to a top block.

It includes a protective component, a flue gas tester body 310 is installed in the protective component, and a driving component is installed at the bottom of the protective component;

[0028] The protective assembly includes a protective box 110, the top of the protective box 110 is an open structure, a cover plate 170 is installed on the top of the protective box 110, two groups of positioning rods 180 are installed on the side walls at both ends of the cover plate 170, multiple groups of first ventilation holes 120 are opened on the side walls around the protective box 110, and the multiple groups of first ventilation holes 120 are arranged at equal distances, a baffle 210 is slidably connected inside the protective box 110, multiple groups of second ventilation holes 220 are opened on the side walls around the baffle 210, and the multiple groups of first ventilation holes 120 and second ventilation holes 220 are arranged at equal distances, and four groups of threaded holes 230 are opened on the bottom of the baffle 210.

[0029] A protective box 110 is provided to protect the main body 310 of the smoke gas tester, so that the main body 310 of the smoke gas tester is not easily impacted by the outside world when the smoke gas tester is not in use; when monitoring the smoke, the first ventilation hole 120 and the second ventilation hole 220 are connected by moving the baffle 210, so that the external smoke enters the protective box 110 to monitor the smoke. At the same time, the protective box 110 can protect the main body 310 of the smoke gas tester, so that the main body 310 of the smoke gas tester is not easily impacted by the outside world during use, thereby making the main body 310 of the smoke gas tester not easily damaged, thereby improving the safety of the main body 310 of the smoke gas tester.

[0030] Two sets of fixing rods 140 are installed on both side walls of the protection box 110 . The fixing rods 140 are rotatably connected to rotating blocks 150 . The rotating blocks 150 are installed with clamping blocks 160 . The clamping blocks 160 are clamped on the positioning rods 180 .

[0031] Two groups of movable grooves 161 are formed on one end of the clamping block 160 close to the rotating block 150 , and springs 162 are installed on the inner walls of the two groups of movable grooves 161 . A movable plate 163 is installed on one end of the two groups of springs 162 , and the two groups of movable plates 163 are respectively slidably connected in the two groups of movable grooves 161 .

[0032] A moving rod 164 is installed on one side of the two groups of moving plates 163 away from the spring 162 , and one end of the two groups of moving rods 164 away from the moving plates 163 is installed on the rotating block 150 .

[0033] When fixing the cover 170, by pulling the block 160, the moving rod 164 drives the moving plate 163 to move in the moving groove 161, stretching the spring 162, and then the block 160 is clamped on the positioning rod 180, and the block 160 is released. Under the action of the spring 162, the block 160 is clamped on the positioning rod 180 to fix the cover 170, thereby installing the smoke tester body 310 in the protective box 110 to protect the smoke tester body 310.

[0034] The driving assembly includes an adjustment slot 410 , which is opened at the bottom of the protective box 110 . A dual-axis motor 430 is installed in the adjustment slot 410 , and two sets of worm gears 420 are transmission-connected to the output end of the dual-axis motor 430 .

[0035] The drive assembly also includes two groups of rotating rods 440, both of which are rotatably connected in the adjustment slot 410, and both groups of rotating rods 440 are installed with worm gears 450, both groups of worm gears 450 are engaged with the worm 420, and both ends of the two groups of rotating rods 440 are installed with first gears 460.

One end of each of the four sets of threaded rods 470 extends into the protective box 110, and each of the four sets of threaded rods 470 is threadedly connected to the four sets of threaded holes 230. Each of the four sets of threaded rods 470 is mounted with a second gear 480, which meshes with the four sets of first gears 460.

[0037] The dual-axis motor 430 drives the worm 420 to rotate, which in turn drives the rotating rod 440 via the worm gear 450. The rotating rod 440 then drives the threaded rod 470 via the first gear 460 and the second gear 480 to rotate. The threaded rod 470 and the threaded hole 230 act to move the baffle 210, connecting the first ventilation hole 120 and the second ventilation hole 220. This allows the smoke tester body 310 to monitor external smoke. When the smoke tester body 310 is not in use, the first ventilation hole 120 and the second ventilation hole 220 are disconnected, and the baffle 210 closes the first ventilation hole 120, thereby protecting the smoke tester body 310.

[0038] Specifically, the internal electrical connection structure of the dual-axis motor 430 and the smoke tester body 310 is well known to those skilled in the art and will not be described in detail herein.
