[0032] A multifunctional multi-gas laser TDLAS detector, comprising:

[0033] A connecting sleeve (1), both ends of the connecting sleeve (1) are fixedly connected to a first flange (2), a circumferential surface of the connecting sleeve (1) is fixedly connected to a temperature sensor (8), the bottom end of the connecting sleeve (1) is fixedly connected to a support rod (4), and the bottom end of the support rod (4) is fixedly connected to a threaded sleeve (5);

[0035] a motor (9), wherein the motor (9) is fixedly connected to the circumferential surface of the connecting sleeve (1);

[0036] An adjustment mechanism is provided in the connecting sleeve (1), and is used to adjust the angle of a gas laser TDLAS detector body (3).

[0037] In a specific embodiment of the present invention, first, a connecting sleeve (1) connects two gas laser TDLAS detector bodies (3), playing the role of a bridge and a support, ensuring that the two detectors maintain a stable connection relationship in structure, facilitating overall installation and use.

[0038] Provide installation locations for the temperature sensor (8) and the motor (9), so that these components can be reasonably arranged in the detector system and work together.

[0039] The first flanges (2) at both ends facilitate connection with external pipelines or equipment, thereby improving the installation convenience and versatility of the detector.

[0040] Second, the first flange (2) serves as a connecting component, enabling the multifunctional multi-gas laser TDLAS detector to be quickly and firmly connected to external equipment or pipelines. The flange connection method has the advantages of good sealing and easy installation and disassembly.

[0041] Ensure that the connection between the detector and the external system is tight and reliable to prevent gas leakage and ensure the accuracy and stability of detection.

[0042] 3. The gas laser TDLAS detector body (3) is the core part of the detector, which includes key components such as laser emission module, receiving module, signal processing module, control module and display module.

[0043] The laser emission module emits laser light of a specific wavelength to excite the gas molecules to be detected and provide a light source for detection.

[0044] The receiving module receives the laser signal after being absorbed by the gas and converts it into an electrical signal to collect the gas absorption information.

[0045] The signal processing module amplifies, filters and digitizes the received electrical signals to extract key information such as gas concentration.

[0046] The control module is responsible for coordinating the work of each module to realize the automatic operation of the detector, such as controlling the intensity and frequency of laser emission and the sensitivity of the receiving module.

[0047] The display module is used to display the detection results and the working status of the detector, so that users can intuitively understand information such as gas concentration.

[0048] Fourth, the support rod (4) provides connection support for the connecting sleeve (1) and the threaded sleeve (5), making the overall structure of the detector more stable.

[0049] The installation height of the detector can be adjusted to suit different installation environments and detection requirements.

[0050] 5. The threaded sleeve (5) is connected by a threaded connection method to facilitate the connection between the detector and the mounting base or other fixing devices. The threaded connection has the advantages of firm installation and strong adjustability.

[0051] The installation angle and position of the detector can be adjusted according to actual needs to improve the flexibility of the detector.

[0052] 6. Temperature sensor (8) monitors the temperature changes of the detector's surrounding environment in real time. Temperature has a certain impact on the physical properties of the gas and the performance of the detector. By monitoring the temperature, the detection results can be compensated for temperature and the accuracy of the detection can be improved.

[0053] When the temperature is too high or too low and may affect the normal operation of the detector, the temperature sensor (8) can sound an alarm to remind the user to take appropriate measures to protect the detector equipment.

[0054] 7. The motor (9) provides a power source for the adjustment mechanism. The operation of the motor (9) can drive the adjustment mechanism to work and achieve the adjustment of the angle of the gas laser TDLAS detector body (3).

[0055] By precisely controlling the rotation speed and direction of the motor (9), the angle of the detector can be precisely adjusted to suit different detection scenarios and requirements.

[0056] 8. The adjustment mechanism adjusts the angle of the gas laser TDLAS detector body (3) according to actual detection needs. This can expand the detection range of the detector and improve the flexibility and adaptability of the detection.

[0057] For example, in a complex piping system or a space-constrained environment, the detector can be better aligned with the gas area to be detected by adjusting the angle, thereby improving the accuracy and reliability of the detection. It should be noted that the specific type of temperature sensor (8) and gas laser TDLAS detector body (3) to be used is selected by relevant technicians familiar with the field, and the above-mentioned temperature sensor (8), gas laser TDLAS detector body (3) and the like are all existing technologies and will not be elaborated in this solution.

[0058] For details, please refer to Figures 1-4 , the regulating mechanism comprises:

[0059] A first transmission rod (301), wherein two first transmission rods (301) are provided, and the two first transmission rods (301) are respectively fixedly connected to adjacent ends of two gas laser TDLAS detector bodies (3);

[0060] Support discs (303), wherein four support discs (303) are provided, and the four support discs (303) are all fixedly connected to the circumferential inner wall of the connecting sleeve (1), and the two first transmission rods (301) are respectively rotatably connected to the four support discs (303);

[0061] A second transmission rod (901), the second transmission rod (901) being rotatably connected to the circumferential inner wall of the connecting sleeve (1), and the second transmission rod (901) being fixedly connected to the output end of the motor (9);

[0062] a second bevel gear (10), the second bevel gear (10) being fixedly connected to the circumferential surface of the second transmission rod (901);

[0063] The first bevel gear (302) is provided with two first bevel gears (302), and the two first bevel gears (302) are respectively fixedly connected to the circumferential surfaces of the two first transmission rods (301), and the second bevel gear (10) is meshed with the two second bevel gears (10).

[0064] In this embodiment: 1. The first transmission rod (301) serves as a key component for connecting the gas laser TDLAS detector body (3) and the support plate (303), and plays the role of transmitting power and adjusting the angle of the detector body.

[0065] When the first transmission rod (301) rotates, it can drive the gas laser TDLAS detector body (3) fixedly connected thereto to rotate, thereby adjusting the angle of the detector to adapt to different detection requirements and environments.

[0066] Second, the support discs (303) provide a stable support and rotation base for the first transmission rod (301). The four support discs (303) are evenly distributed on the inner circumference of the connecting sleeve (1), ensuring that the first transmission rod (301) remains stable during rotation without shaking or deflection.

[0067] The axial movement of the first transmission rod (301) is restricted so that the first transmission rod (301) can only rotate around its own axis, thereby ensuring the accuracy and reliability of angle adjustment.

[0068] 3. The second transmission rod (901) serves as an intermediate link in power transmission, transmitting the output power of the motor (9) to the second bevel gear (10).

[0069] The second transmission rod (901) rotates under the drive of the motor (9), driving the second bevel gear (10) fixedly connected thereto to rotate, thereby starting the operation of the entire adjustment mechanism.

[0070] Fourth, the second bevel gear (10) cooperates with the first bevel gear (302) to realize the diversion and transmission of power. When the second bevel gear (10) rotates, it will drive the first bevel gear (302) to rotate due to the engagement with the two first bevel gears (302).

[0071] By changing the rotation direction, the horizontal power output by the motor (9) is converted into vertical power, thereby driving the first transmission rod (301) to rotate, thereby achieving adjustment of the angle of the gas laser TDLAS detector body (3).

[0072] 5. The first bevel gear (302) is fixed on the circumferential surface of the first transmission rod (301), receives the power transmitted by the second bevel gear (10), and converts it into the rotation of the first transmission rod (301).

[0073] The two first bevel gears (302) are meshed with the second bevel gear (10) to ensure smooth power transmission and synchronization of angle adjustment. When the second bevel gear (10) rotates, the two first bevel gears (302) rotate simultaneously, so that the two gas laser TDLAS detector bodies (3) can be adjusted at the same angle, ensuring consistency and accuracy of detection.

[0074] For details, please refer to Figure 1-Figure 3 The bottom end of the support rod (4) is fixedly connected to a threaded sleeve (5), and the circumferential surface of the threaded sleeve (5) is fixedly connected to a fixing plate (7).

[0075] In this embodiment, the fixing plate (7) is fixed to the circumferential surface of the threaded sleeve (5), thereby increasing the contact area and stability of the threaded sleeve (5) and the external connection. After the detector is installed, the fixing plate (7) can share part of the weight and force of the detector, preventing the threaded sleeve (5) from loosening or being damaged due to uneven force. The threaded sleeve (5) serves as an intermediate component connecting the support rod (4) and the mounting base or other fixing device. Through the threaded connection method, it is convenient to firmly connect the detector as a whole with the external structure, ensuring that the detector maintains a stable position during use.

[0076] For details, please refer to Figure 2 The bottom end of the threaded sleeve (5) is fixedly connected to a second flange (6), and the bottom end of the second flange (6) is fixedly connected to a plastic pad (601).

[0077] In this embodiment: the second flange (6) facilitates the connection of the detector to an external fixed structure or other equipment. The flange connection method has the advantages of easy installation and disassembly, firm connection, and good sealing. When the detector is vibrated or impacted during operation, the plastic pad (601) can play a role in buffering and shock absorption, protecting the precision components inside the detector from damage.

[0078] For details, please refer to Figures 1-4 A fixing plate (7) is fixedly connected to the circumferential surface of the connecting sleeve (1).

[0079] In this embodiment, the fixing plate (7) is fixedly connected to the circumferential surface of the connecting sleeve (1) to provide additional support and reinforcement for the connecting sleeve (1). During the operation of the detector, the connecting sleeve (1) needs to bear the weight of the two gas laser TDLAS detector bodies, the support rod (4) and other components, as well as possible external vibration and impact forces. The presence of the fixing plate (7) can disperse these forces, improve the structural strength and stability of the connecting sleeve (1), and ensure the firmness and reliability of the overall structure of the detector.

[0080] The working principle and use process of the utility model: Multifunctional multi-gas detection: The multifunctional multi-gas laser TDLAS detector is provided with two gas laser TDLAS detector bodies (3), each detector body comprising a laser emission module, a receiving module, a signal processing module, a control module and a display module.

[0081] The laser emission module emits laser light of a specific wavelength to excite the gas molecules to be detected.

[0082] The receiving module receives the laser signal after being absorbed by the gas and converts it into an electrical signal.

[0083] The signal processing module amplifies, filters and digitizes the received electrical signals to extract key information such as gas concentration.

[0084] The control module is responsible for coordinating the work of each module and realizing the automatic operation of the detector.

[0085] The display module is used to display the detection results and the working status of the detector, so that users can intuitively understand information such as gas concentration.

[0086] Through such a design, the two detector bodies can work simultaneously to detect multiple gases and meet the needs of simultaneous detection of multiple gases.

[0087] Improve detection accuracy and stability, and enhance anti-interference capabilities:

[0088] It adopts advanced laser TDLAS technology, which has the advantages of high detection accuracy and fast response speed.

[0089] A temperature sensor (8) is fixedly connected to the circumferential surface of the connecting sleeve (1) to monitor the temperature change of the environment around the detector in real time. Temperature has a certain influence on the physical properties of the gas and the performance of the detector. By monitoring the temperature, the detection result can be temperature compensated to improve the accuracy of the detection.

[0090] When the temperature is too high or too low and may affect the normal operation of the detector, the temperature sensor (8) can sound an alarm to remind the user to take corresponding measures to protect the detector equipment, thereby improving the stability and anti-interference ability of the detector.

[0091] Adjust the angle of the detector body:

[0092] The motor (9) provides a power source for the regulating mechanism, and its output end is fixedly connected to the second transmission rod (901).

[0093] The second transmission rod (901) is rotatably connected to the circumferential inner wall of the connecting sleeve (1), driving the second bevel gear (10) fixedly connected to the circumferential surface thereof to rotate.

[0094] The two first transmission rods (301) are respectively fixedly connected to the adjacent ends of the two gas laser TDLAS detector bodies (3), and the circumferential surfaces of the two first transmission rods (301) are respectively fixedly connected to first bevel gears (302), and the two first bevel gears (302) are meshed with the second bevel gear (10).

[0095] The four support plates (303) are all fixedly connected to the circumferential inner wall of the connecting sleeve (1), and the two first transmission rods (301) are respectively rotatably connected to the four support plates (303).

[0096] When the motor (9) is running, the second transmission rod (901) drives the second bevel gear (10) to rotate, and through cooperation with the first bevel gear (302), power is transmitted to the first transmission rod (301), so that the first transmission rod (301) drives the gas laser TDLAS detector body (3) to rotate, thereby achieving adjustment of the detector angle.

[0097] In this way, according to actual detection needs, for example, in a complex piping system or a space-constrained environment, the detector can be adjusted to better align with the gas area to be detected, thereby improving the accuracy and reliability of detection.

[0098] In summary, the multifunctional multi-gas laser TDLAS detector solves the problems in the existing technology of only being able to detect one or several specific gases, the need to improve detection accuracy and stability, and weak anti-interference ability in complex environments through the above operation process.
