The device comprises an outer box body, wherein one side of the outer box body is rotationally matched with a plurality of exhaust shifting plates; the threaded rod is rotationally matched with one side of the outer box body, a sliding block is in threaded fit with the threaded rod, a rotating roller is rotationally matched with one side of the sliding block, and a gear is arranged at one end of the rotating roller. Through the arrangement of the rotating roller, the sliding block drives the rotating roller to move under the action of the threaded rod, and due to the fact that the gear is matched with the teeth in a meshed mode, the rotating roller can rotate, so that the rotating roller which rotates drives the brush to clean impurities on one side of the exhaust shifting plate, the problem that impurities are accumulated on one side of the exhaust shifting plate is solved, and the service life of the exhaust shifting plate is prolonged. The influence of impurity accumulation on one side of the exhaust shifting plate on the heat dissipation efficiency of the outer box body is reduced, and the service life of parts in the outer box body is prolonged.

Description

Technical Field

[0001] The utility model belongs to the field of VOCs online monitoring, and specifically relates to a VOCs online monitoring system calibration cabinet. Background Art

[0002] VOCs are a type of volatile organic compound, which refers to organic compounds with a saturated vapor pressure greater than 70 Pa at room temperature and a boiling point below 260°C at normal pressure, or all organic compounds with corresponding volatility whose vapor pressure is greater than or equal to 10 Pa at 20°C.

[0003] The patent application with publication number CN211406518U discloses a control cabinet for VOCs equipment, including: an outer box body, the top of the outer box body is threadedly sleeved with an adjusting screw, and the top of the outer box body is movably sleeved with guide rods located on both sides of the adjusting screw, the bottom of the guide rod is fixedly installed with a fixing plate, and the bottom of the fixing plate is fixedly installed with an upper cooling fan, and the bottom of the inner cavity of the outer box body is fixedly installed with an electrical fixing plate. The control cabinet of the VOCs equipment dissipates heat for electronic components through the upper and lower cooling fans at the upper and lower ends, thereby reducing the temperature of the electronic components, avoiding the long-term accumulation of heat inside the electronic components, reducing the damage of heat to the electronic components, and increasing the service life of the electronic components. At the same time, by rotating the adjusting screw, the fixing plate is driven to move up and down, and the upper cooling fan is driven to move up and down.

[0004] However, the above technology has the following disadvantages when used:

[0005] It is described in paragraph 0027 of the above-mentioned document that "one end of the fixed sleeve 11 is fixedly connected to the reset spring 10, and the other end of the fixed sleeve 11 is fixedly connected to the side of the rectangular groove, the reset spring 10 is mirror-imaged at both ends of the fixed rod 8, the length of the exhaust plate 9 is the same as the width of the rectangular groove, and the reset spring 10 outside the fixed rod 8 has elastic potential energy. When the upper cooling fan 5 and the lower cooling fan 7 are closed, there is no airflow inside the control cabinet. At this time, the exhaust plate 9 is in a closed state, which avoids the entry of dust and reduces the impact of dust on electronic components. It solves the problem of easy entry of dust in the previous open air outlet structure, and further improves the service life of electronic components." It can be seen that the temperature inside the outer box 1 is cooled by adjusting the position of the exhaust plate 9, and the outer wall of the exhaust plate 9 is prone to accumulate impurities when in use, thereby reducing the efficiency of heat dissipation inside the outer box 1, and causing the internal components of the outer box 1 to be damaged due to high temperature.

[0006] Therefore, a VOCs online monitoring system calibration cabinet is proposed to solve the above drawbacks. Utility Model Content
