Description

Technical Field

[0001] This application relates to the field of gas detection, and more particularly to a gas detector for multi-gas detection. Background Technology

[0002] Gas detectors play a crucial role in numerous fields such as industrial production, environmental monitoring, and safety protection. They are used to detect the concentration of various gases in the air in real time, providing important safeguards for production safety, environmental protection, and human health. With the diversification of gas detection needs, multi-gas detectors have emerged. By equipping them with multiple detection heads, they can detect multiple gases simultaneously, greatly improving the comprehensiveness and accuracy of detection.

[0003] However, in practical applications, especially in environments with high levels of dust and debris, such as industrial plants, mines, and construction sites, dust, particulate matter, and other impurities in the air can easily clog the air inlet of the detector head. This problem is even more pronounced for gas detectors with multiple detector heads. Once the air inlet is blocked, gas cannot enter the detector head normally, which can lead to deviations or failures in the detection results, affecting the accurate judgment of gas concentration and thus threatening production safety and the effectiveness of environmental monitoring. Long-term blockage can also damage the detector head, increasing equipment maintenance costs and downtime, and reducing work efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that the multiple detection heads of a gas detector are susceptible to the influence of dust and debris in the environment during use. Therefore, a multi-gas detection gas detector is proposed to solve the above problems. Utility Model Content

Limit bolts are fixedly installed at the four corners of the bottom end of the fixed support plate. A support frame is installed on the outer surface of the limit bolts at the bottom end of the fixed support plate. A fastening nut is threaded onto the support frame and a dustproof net is fixedly installed at the bottom end of the support frame. Guide rods are fixedly connected at the four corners of the bottom end of the fixed support plate. A movable frame is installed on the outer surface of the guide rods at the bottom end of the dustproof net. A positioning component is also provided on the outer surface of the guide rods for limiting and fixing the movable frame.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a gas detector capable of detecting multiple gases. (Refer to...) Figure 1-4 A multi-gas detector includes a gas detection device 1, which serves as the main body of the detector and is used to process and display detection data. Several connecting pipes 2 are provided at the bottom of the gas detection device 1, which are used to transmit gas to a detection head 3. A detection head 3 is installed at the bottom of each connecting pipe 2, and is used to detect parameters such as the concentration of different gases. A connecting mechanism is provided between the connecting pipes 2 and the detection head 3. The connecting mechanism includes a connecting kit 13, which is movably fitted onto the outer surface of the connecting pipes 2. An internal thread is provided on one side of the inner wall of the connecting kit 13, and an external thread 14 is provided on the top of the outer surface of the detection head 3. The external thread 14 and the internal thread in the connecting kit 13 are mutually compatible. By rotating the connecting kit 13, the connecting pipes 2 and the detection head 3 can be quickly connected or separated, facilitating the installation, maintenance, and replacement of the detection head 3.

[0023] A fixed support plate 4 is fixedly installed at the bottom of the gas detection device 1 near the connecting pipe 2. The fixed support plate 4 is used to support and fix other components. Limit bolts 5 are fixedly installed at the four corners of the bottom of the fixed support plate 4. A support frame 6 is installed on the outer surface of the limit bolts 5 at the bottom of the fixed support plate 4. The support frame 6 is used to install a dustproof net 8. The outer surface of the limit bolts 5 abuts against the support frame 6 and is threaded with a fastening nut 7. By tightening the fastening nut 7, the support frame 6 can be fixed to the fixed support plate 4. The dustproof net 8 is fixedly installed at the bottom of the support frame 6. The dustproof net 8 is made of fine metal mesh or polymer material mesh, which can effectively block dust, particulate matter and other impurities in the air, preventing them from entering the air inlet of the detection head 3, ensuring the normal operation and detection accuracy of the detection head 3.

[0024] Guide rods 9 are fixedly attached to the bottom of the fixed support plate 4 near the four corners. The bottom of the support frame 6 is placed on the outer surface of the guide rods 9 and a movable frame 10 is installed. The outer surface of the guide rods 9 is also provided with a positioning component, which includes a first magnetic block 11, which is fixedly installed at the top of the outer surface of the guide rods 9. Second magnetic blocks 12 are fixedly attached to the upper surface of the movable frame 10 near the four corners. The first magnetic block 11 and the second magnetic block 12 attract each other magnetically. Through magnetic attraction, the movable frame 10 can be initially positioned. At the same time, the guide rods 9 cooperate with the second through hole on the movable frame 10 to guide and further limit the movement, ensuring that the movable frame 10 is installed stably. The support frame 6 has a through hole No. 1 at the bottom near the four corners. One side of the outer surface of the limiting bolt 5 is located in the through hole No. 1, and the limiting bolt 5 and the through hole No. 1 are fitted together. The upper surface of the movable frame 10 has a through hole No. 2 at the four corners. The outer diameter of the guide rod 9 is smaller than the inner diameter of the through hole No. 2, and one side of the outer surface of the guide rod 9 is located in the through hole No. 2. These structural designs ensure the installation accuracy and stability between the components.

[0025] The implementation principle of a multi-gas detection gas detector according to an embodiment of this application is as follows: During use, the dustproof net 8 effectively blocks dust and debris, preventing them from approaching the air inlet of the detection head 3. When it is necessary to install or replace the detection head 3, quick connection or disassembly is achieved by rotating the connecting kit 13 and utilizing its cooperation with the external thread 14 of the detection head 3. The support frame 6 is fixed to the fixed support plate 4 by the limiting bolts 5 and the fastening nuts 7. The movable frame 10 is stably installed at the bottom of the support frame 6 by the magnetic attraction of the first magnetic block 11 and the second magnetic block 12 and the guiding and limiting of the guide rod 9, ensuring the stable position of the dustproof net 8 and effectively playing its dustproof role, thereby ensuring the detection accuracy and long-term stable operation of the gas detector.
