Description

Technical Field

[0001] The utility model relates to the technical field of laboratory environment monitoring, in particular to a laboratory environment self-adaptive regulating device based on the Internet of Things. Background Art

[0002] The chemistry laboratory is an important place for students to conduct chemistry experiments. However, during the chemistry experiments, harmful gases to the human body are easily produced, causing serious accidents or even explosions, which have serious negative impacts on the school and society. Therefore, the monitoring of chemistry laboratories has attracted people's high attention. Due to the wide variety of toxic gases or flammable and explosive gases, if the harmful gases are not discovered in time, it is easy to cause safety accidents.

[0003] Most of the existing monitoring devices are fixed in place. Due to the wide variety of toxic and harmful gases and the different densities of different gases, it is easy to cause stratification in the distribution of toxic and harmful gases. The existing monitoring devices are fixed in place and cannot detect gases at different heights, resulting in the inability to detect harmful gases, posing a major safety hazard.

[0004] The existing patent (Announcement No.: CN 210302863 U) discloses a chemical laboratory environment monitoring device, which includes two slide rails, and the locking plate is fixed to the wall by screws and other standard parts. Air detection instruments such as carbon dioxide sensors, carbon monoxide sensors, and mercury vapor testers can be installed on the sensor mounting plate. When performing air detection, the servo motor is started, and the servo motor drives the winding wheel to rotate forward when working. At this time, the winding wheel reels the pull rope, and the pull rope pulls the purification device and the sensor mounting plate to move upward. During the movement, the detection instrument on the sensor mounting plate detects the air. When the purification device moves to the top, the servo motor reverses, and the winding wheel loosens the pull rope. Under the gravity of the purification device itself, the purification device moves downward. During the up and down movement of the purification device and the sensor mounting plate, the detection instrument can detect air at different heights, and when harmful gases are detected, the purification device performs preliminary purification of the air, which has a good emergency effect and solves the problem that different gases have different densities, which easily causes the distribution of toxic and harmful gases to be layered. Phenomenon, and the existing monitoring device is fixed in position and cannot detect gases at different heights, resulting in the inability to detect harmful gases, which poses a great safety hazard. The two slide rails can be fixed by plugging in the plug-in column and the plug-in hole. According to the actual height inside the laboratory, the appropriate additional slide rail can be selected to make the device suitable for laboratories with different indoor heights, and the scope of application is wider. The sliding block is set as a convex block to prevent the sliding block from detaching from the inside of the slide rail, and the ball bearing can make the sliding of the sliding block smoother, and at the same time has a certain anti-tilt effect. When harmful gases are found, the fan sucks the external wind into the inside of the wind tube, and filters the gas through the filter to block the large particles of impurities therein, and then purifies the air through a small purifier. At the same time, the filter is set to be plug-in, which is convenient for the subsequent removal or replacement of the filter, and the sealing seat seals the gap between the filter and the filter box to prevent air leakage. The pulley changes the direction of the pull rope and reduces the possibility of the pull rope being entangled inside the installation box.

[0005] However, the above technical solution still has certain defects. The filter box is raised and lowered by controlling the winding wheel and the pull rope, and the filter box descends by its own gravity. When the trapezoidal block and the slide rail are relatively stuck, the filter box cannot move downward normally, and the pull rope cannot provide a downward force. Therefore, a laboratory environment adaptive adjustment device based on the Internet of Things is proposed. Utility Model Content
