Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide detection technology, and in particular to a carbon dioxide concentration measuring device under high humidity conditions. Background Technology

[0002] The increase in carbon dioxide in the atmosphere is a threat to the development of human civilization, especially its impact on the environment. Of course, many relevant institutions are now researching methods to detect and control carbon dioxide. Carbon dioxide detectors are a powerful guarantee for people to monitor this gas. A carbon dioxide detector is a special device used to detect the carbon dioxide content in the atmosphere and other related parameters. This device usually has a carbon dioxide content component installed and is widely used in most industries closely related to life, such as petroleum, home furnishing, chemical, meteorology, and chemistry. A carbon dioxide concentration detection device disclosed in CN215525520U includes: a housing, a temperature and humidity control device, and a carbon dioxide sensor; the housing forms a sealed cavity inside, and the housing wall is provided with an air inlet and an air outlet; the temperature and humidity control device is installed in the cavity to regulate the temperature and humidity of the gas in the cavity; the carbon dioxide sensor is used to detect the concentration of carbon dioxide in the gas in the cavity.

[0003] Although this invention provides a constant temperature and humidity detection environment for the gas inside the chamber through a temperature and humidity control device, preventing the temperature and humidity of the gas from affecting the detection results when detecting carbon dioxide concentration, it is suitable for accurate detection of carbon dioxide concentration in greenhouses. However, this device has the following disadvantages: (1) Failure to dehumidify the gas will still affect the test results and lead to inaccurate results; (2) The temperature of the gas and the temperature of the detector are not the same, which will cause water to condense on the detector and affect the detection results; (3) The height cannot be adjusted. Different heights result in different gas concentrations, which will also affect the test results. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a carbon dioxide concentration measuring device in a high humidity environment that is highly practical, easy to operate, and has a simple structure. This solves the problems mentioned in the background art, such as the lack of dehumidification, condensation on the detector, and the inability to adjust the height.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A carbon dioxide concentration measuring device for high humidity environments includes a base, a support mechanism fixedly connected to the bottom of the base, a storage cylinder fixedly connected to the top surface of the base, a lifting mechanism fixedly connected to the inner bottom surface of the base, a telescopic rod fixedly connected to one end of the lifting mechanism, a heating mechanism fixedly connected to the top surface of the telescopic rod, a heating wire fixedly connected inside the heating mechanism, a drying mechanism fixedly connected to one side of the heating mechanism, a drying box movably connected inside the drying mechanism, and an exhaust pipe fixedly connected to the other side of the heating mechanism.

[0006] Optionally, the drying mechanism includes an air inlet pipe fixedly connected to one side of the heating mechanism, an air intake fan fixedly connected inside the air inlet pipe, the surface of the drying box movably connected to the inside of the air inlet pipe, a solid desiccant movably connected inside the drying box, and the air intake fan acting as a suction fan to draw in the gas.

[0007] Optionally, the heating mechanism includes a heating chamber fixedly connected to the top surface of the telescopic rod, a detector fixedly connected inside the heating chamber, and the surface of the heating wire fixedly connected to the inside of the heating chamber, the heating wire serving to heat the detector.

[0008] Optionally, the lifting mechanism includes a spring fixedly connected to the inner bottom surface of the base, the bottom surface of the telescopic rod fixedly connected to one end of the spring, a connecting rod fixedly connected to the surface of the telescopic rod, a steel wire rope fixedly connected to the surface of the connecting rod, a handle fixedly connected to one end of the steel wire rope, and the handle rotatably connected to the surface of the storage cylinder, the handle serving to retract the steel wire rope.

[0009] Optionally, a PLC controller is fixedly connected to the surface of the storage tube, a display screen is fixedly connected to the surface of the storage tube, a sliding groove is opened on one side of the storage tube, a connecting rope is fixedly connected to one side of the storage tube, and a locking hook is fixedly connected to one end of the connecting rope, the locking hook serving to fix it.

[0010] Optionally, the surface of the drying box has several holes, and the surface of the air inlet pipe has a slot, the size of which matches the size of the drying box. The solid desiccant is calcium sulfate or calcium chloride, and the solid desiccant plays the role of absorbing moisture.

[0011] Beneficial effects: This utility model provides a carbon dioxide concentration measuring device in a high humidity environment, which has the following beneficial effects: 1. This carbon dioxide concentration measuring device for high humidity environments, through the setup of a drying mechanism and drying box, as well as a heating mechanism and heating wire, allows for the detection of carbon dioxide concentration in the environment. When the PLC controller is turned on, the intake fan and heating chamber are activated. The intake fan draws surrounding gas into the intake pipe, where it passes through the solid desiccant in the drying box to dry the moisture, improving dehumidification efficiency. The dried gas then enters the heating chamber, which heats the detector to prevent condensation due to temperature inconsistencies between the gas and the detector's surface temperature, thus improving the accuracy of the detection results.

[0012] 2. This carbon dioxide concentration measuring device for high humidity environments, through the setting of a lifting mechanism and a telescopic rod, allows for the detection of gas concentration at different heights when measuring carbon dioxide concentration in the environment. Turning the handle retracts the steel wire rope, which pulls the connecting rod, causing it to move upwards. Once the desired height is reached, the locking hook engages the handle to fix the height, enabling the detection of gas concentration at different heights. This improves the diversity of detection results and facilitates analysis. When not in use, the locking hook is released, and the spring connected to the bottom of the telescopic rod rebounds, retracting the telescopic rod and reducing space usage.

[0018] Please see Figure 3 The heating mechanism 6 includes a heating chamber 601 fixedly connected to the top surface of the telescopic rod 5. A detector 602 is fixedly connected inside the heating chamber 601. The surface of the heating wire 7 is fixedly connected to the inside of the heating chamber 601.

The handle 404 serves to retract the steel wire rope 403.

[0020] Please see Figure 1 A PLC controller 11 is fixedly connected to the surface of the storage tube 3, and a display screen 12 is fixedly connected to the surface of the storage tube 3. A sliding groove is opened on one side of the storage tube 3, and a connecting rope 14 is fixedly connected to one side of the storage tube 3. A locking hook 13 is fixedly connected to one end of the connecting rope 14, and the locking hook 13 serves to fix it.

[0021] Please see Figure 2 The surface of the drying box 9 has several holes, and the surface of the air inlet pipe 801 has a slot. The size of the slot matches that of the drying box 9. The solid desiccant 803 is made of calcium sulfate or calcium chloride and plays the role of absorbing moisture.

When no longer needed, the locking hook 13 is released, and the spring 401 connected to the bottom of the telescopic rod 5 rebounds, retracting the telescopic rod 5 and reducing space usage.
