Description

Technical Field

[0001] This utility model relates to the field of gas detection equipment technology, specifically to an installation structure for a gas composition measuring device. Background Technology

[0002] The TDLAS gas composition measuring device (tunable laser absorption spectroscopy for measuring gas composition, or simply gas composition measuring device) utilizes the narrow linewidth and tunable characteristics of a laser to scan the characteristic absorption spectral lines of the gas being measured, thereby achieving qualitative and quantitative measurement of trace gases. In conventional gas composition measuring devices, the gas detection cell is directly mounted on the laser emission platform via a bracket. In this case, slight vibrations accompanying laser operation can cause the gas detection cell to resonate, leading to deviations in laser beam illumination. Furthermore, once installed, the gas detection cell cannot be fine-tuned for horizontal adjustment, resulting in a slight tilt deviation in its installation position. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The installation structure of this gas composition measuring device, by setting a rubber pad between the outer shell and the mounting bracket, with multiple sets of deformation holes in the rubber pad, utilizes the shock absorption performance of the rubber pad to reduce the transmission of external vibration force to the inner shell, ensuring that the entire gas detection device is not affected by external vibration; at the same time, driving one of the locking nuts to move upward along the screw will cause the outer shell to contract downward and close to the mounting bracket, and its rubber pad and spring will also be compressed, thereby controlling one corner of the outer shell to tilt downward.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a technical solution: an installation structure for a gas composition measuring device, including an inner shell 1, an outer shell 10 fixedly installed on the outside of the inner shell 1, a concave mirror 2 fixedly installed on the left side of the inner wall of the inner shell 1, and two symmetrically arranged concave mirrors 3 fixedly installed on the right side of the inner wall of the inner shell 1. A laser collimator illuminates the upper concave mirror 3 with a laser beam, which is then refracted by the upper concave mirror 3 into the concave mirror 2. The concave mirror 2 then refracts the laser beam back to the lower concave mirror 3, which in turn refracts the laser beam to an external laser detector, increasing the beam travel path and improving the gas detection time. A pressure sensor 4 and a temperature sensor 5 are fixedly installed on the inner wall of the inner shell 1 in the gaps of the laser path. The temperature sensor is a platinum resistance thermometer, and the pressure sensor is a piezoelectric ceramic sensor. Both sensors detect the pressure and temperature of the gas, respectively, allowing users to understand the gas conditions.

[0015] Please see Figure 1-3 An air outlet 6 is fixedly embedded on the front of the inner shell 1. A three-way connector of a pressure gauge is threaded to the outer side of the air outlet 6. The other end of the three-way connector of the pressure gauge is connected to an external constant pressure device. Its function is to ensure the internal pressure of the inner shell 1 is stable. An air inlet 9 is fixedly embedded on the back of the inner shell 1. A three-way valve is threaded to the outer side of the air inlet 9. An air pump is threaded to the other end of the three-way valve. The air pump's suction end is connected to an external gas distribution device. Its function is to inject the gas to be tested into the inner shell 1.

[0016] Please see Figure 1-3 The inner shell 1 has a laser detector mounting connector 7 and a laser collimator mounting connector 8 fixedly embedded on its left side. The bottom of the outer shell 10 is provided with a rubber pad 12 to reduce vibration. The bottom of the rubber pad 12 is provided with a mounting bracket 14. A connecting component 15 is interspersed between the rubber pad 12 and the mounting bracket 14, which can adjust the level of the entire gas detection equipment.

[0017] Please see Figure 1-3A heating wire 11 is provided between the outer shell 10 and the inner shell 1, which heats the gas being detected. The heating wires 11 are arranged separately from the positions of the outlet nozzle 6 and the inlet nozzle 9 to prevent the heating wires 11 from interfering with the two nozzles. A deformation hole 13 is provided inside the rubber pad 12, which is used when the rubber pad 12 is deformed. A through hole corresponding to the connecting component 15 is provided on the surface of the rubber pad 12.

[0018] Please see Figure 4-5 The connecting assembly 15 includes an externally threaded ball joint 151, which is threadedly connected to the bottom of the housing 10. The bottom of the housing 10 also has a corresponding threaded groove. A connecting ball 152 is movably installed inside the externally threaded ball joint 151. A screw 153 is fixedly installed at the bottom of the connecting ball 152, extending downwards into a through hole in the mounting bracket 14. A spring 154 and a limiting plate 155 are respectively fitted onto the outer side of the screw 153. Both the spring 154 and the limiting plate 155 are located in through holes on the surface of the rubber pad 12. A locking nut 156 is threadedly connected to the outer side of the screw 153. The locking nut 156 is located below the mounting bracket 14. The housing 10 is detachably mounted to the mounting bracket 14 via the externally threaded ball joint 151, the connecting ball 152, the screw 153, and the locking nut 156.

[0019] By providing a rubber pad 12 between the outer shell 10 and the mounting bracket 14, with multiple sets of deformation holes 13 in the rubber pad 12, the shock absorption performance of the rubber pad 12 reduces the transmission of external vibration force to the inner shell 1, ensuring that the entire gas detection device is not affected by external vibration. At the same time, driving one of the locking nuts 156 to move upward along the screw 153 causes the outer shell 10 to contract downward toward the mounting bracket 14, and its rubber pad 12 and spring 154 are also compressed, thereby controlling one corner of the outer shell 10 to tilt downward. Simultaneously driving the locking nuts 156 of the four connecting components 15 allows for fine-tuning of the horizontal position of the four corners of the outer shell 10, ensuring that the overall gas detection device is in a horizontal state and improving the accuracy of laser penetration.
