[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-4This utility model relates to a flame detector testing device, comprising a workbench 1 and a gas cylinder 2. A testing box 3 is mounted on the workbench 1, and the testing box 3 is equipped with a sealing mechanism, a ventilation mechanism, a lighting mechanism, a detector assembly mechanism, and a camera mechanism. A support mechanism and a drive motor 4 are located at the bottom of the workbench 1. An installation groove is formed at the bottom of the testing box 3, and a bearing seat 5 is mounted on the installation groove. An adjusting plate 6 is mounted on the bearing seat 5, and a burner 7 is mounted on the adjusting plate 6. The bottom of the workbench 1 is connected to the testing box 3 via a through hole 8. A gas pipe 9 is mounted on the gas cylinder 2, and the gas pipe 9 passes through the through hole 8 and is connected to the... The burner 7 includes a detector assembly mechanism comprising a threaded groove and a threaded ring 10. The threaded groove is located at the top of the detection box 3, and the threaded ring 10 is threadedly connected to the threaded groove. A support ring 11 is provided on the inner wall of the threaded ring 10, and a flame detector 12 is placed at the top of the support ring 11. In this embodiment, the operator places the flame detector 12 on the support ring 11 of the threaded ring 10 for support and storage, and then threads the threaded ring 10 onto the threaded groove, thereby quickly assembling the flame detector 12. By opening the sealing mechanism, the operator can push the flame detector 12 upwards from below the threaded ring 10 to remove the flame detector 12, facilitating replacement with the next flame detector. The detector 12 performs testing operations. When storing and testing flame detectors 12 of different sizes, the threaded ring 10 can be rotated to disengage from the threaded groove, allowing for the replacement of support rings 11 of different sizes that are suitable for storing the flame detectors 12. This facilitates the storage and testing of different models of flame detectors 12. During testing, the front of the testing box 3 is sealed by a sealing mechanism. Then, the burner 7 is used to ignite the flame. Combustion gas is supplied to the burner 7 by connecting the gas pipe 9 to the gas tank 2. Then, the drive motor 4 is used, and the output of the drive motor 4 drives the adjustment plate 6 to rotate at an angle. The bearing seat 5 enables the adjustment disc 6 to rotate stably, thereby adjusting the angular position of the burner 7 inside the test chamber 3. Through reciprocating rotation, it can rotate normally within a limited distance of the gas pipe 9, preventing the gas pipe 9 from becoming tangled. By adjusting the position of the burner 7, it is convenient to simulate the flame at different positions to test the flame detector 12. The ventilation mechanism ensures air circulation between the inside and outside of the test chamber 3, ensuring the normal combustion of the burner 7. The lighting mechanism is located around the inside of the test chamber 3, which facilitates the simulation of testing the flame detector 12 under different lighting conditions. It can comprehensively simulate the complex working environment of the flame detector 12, improving the comprehensiveness and accuracy of the test.

[0023] To facilitate blocking external light from entering the testing chamber 3, the sealing mechanism in this design includes a sealing groove and a sealing plate 13. The sealing groove is located at the top of the testing chamber 3, and the sealing plate 13 is located in the sealing groove. By moving the sealing plate 13 up and down in the sealing groove, a sealing structure is formed for the testing chamber 3, reducing interference from light inside and outside the chamber and improving the accuracy of the test.

[0024] To test the flame detector 12 under different lighting conditions, this design includes an illumination mechanism comprising an illumination group 14. The illumination group 14 is installed on both sides and the rear of the inner wall of the testing chamber 3. The illumination group 14 is also embedded in one side of the sealing plate 13. By controlling the switching and brightness of the illumination group 14, the light intensity and illumination range within the testing chamber 3 can be adjusted to simulate different lighting environments. This allows for the simulation of various lighting conditions, including daytime, nighttime, strong light, and weak light, to test the sensitivity and accuracy of the flame detector 12 under different lighting environments, further improving the comprehensiveness of the detection.

[0025] To facilitate air circulation between the testing chamber 3 and the outside air, the ventilation mechanism in this design includes ventilation pipes 15 installed at the rear of the testing chamber 3. Two ventilation pipes 15 are symmetrically arranged, allowing for air exchange between the inside and outside of the testing chamber 3. The filters 16 filter impurities from the air entering the chamber, preventing interference with the experiment and promptly removing exhaust gases and excess fuel produced during combustion within the testing chamber 3, ensuring fresh air inside and providing a good environment for the experiment. This also avoids safety hazards caused by fuel buildup.

[0026] To facilitate observation of the internal state of the testing chamber 3 during testing, this design includes a camera 17 mounted on the top inner wall of the testing chamber 3. The camera 17 is equipped with a high-temperature resistant transparent cover 18. Operators can observe the test situation in real time through the camera 17 without opening the testing chamber 3, thus avoiding the impact of environmental changes caused by opening the chamber on the test results. The high-temperature resistant transparent cover 18 ensures the normal operation of the camera 17 in high-temperature environments, extending its service life.

[0027] In order to accurately adjust the position and angle of the burner 7, the drive motor 4 in this solution is a servo motor. The servo motor has high-precision speed control and position control capabilities, and can accurately drive the adjustment disk 6 to rotate, so as to achieve precise adjustment of the burner 7 angle.

[0028] To stably support the workbench 1, in this design, the support mechanism includes support legs 19 and shock-absorbing pads 20. The support legs 19 are fixedly installed at the four corners of the bottom of the workbench 1, and the shock-absorbing pads 20 are fixedly installed at the bottom of the support legs 19. The support legs 19 support the weight of the entire device, ensuring its stability. The shock-absorbing pads 20 are elastic and can absorb vibrations generated during the operation of the device, as well as vibrations transmitted to the device from the outside.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
