Description

Technical Field

[0001] The present invention relates to the technical field of flame detection, and particularly relates to a test device for a flame detector. Background Art

[0002] Flame detectors play a crucial role in industrial, commercial, and home safety protection systems. Their core function is to quickly capture flame signals and instantly trigger alarms, thus building the first line of defense for the safety of people's lives and property. With the increasing strictness of fire safety standards and the rising complexity of fire hazards, the demands for the accuracy and comprehensiveness of detector performance verification have become more prominent.

[0003] In the prior art, due to the over-simplification of the test scenario, which only focuses on the detector's response to flames under ideal conditions and does not consider the interference of multiple light sources in complex field environments, the performance of the detector in the real environment when facing the interference of various intertwined light sources is unclear, and the risks of false alarms and missed alarms are difficult to measure. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a test device for a flame detector, including: a frame, a horizontal moving guide rail is fixedly connected to the inner side of the frame, a sliding adjustment seat is slidably connected to the outer side of the horizontal moving guide rail, a servo motor is fixedly connected to the outer side of the sliding adjustment seat, an installation platform is fixedly connected to the output end of the servo motor, a light box is fixedly connected to the top of the frame. By setting the horizontal moving guide rail, the sliding adjustment seat can move on the surface of the frame, thereby realizing the adjustment of the distance between the flame detector and the light source. The servo motor can drive the installation platform to rotate, thereby realizing the angle adjustment of the flame detector, and the response performance of the flame detector at different detection angles can be analyzed;

[0005] A light source assembly, the light source assembly is used to simulate complex and diverse interference light source environments for the test of the flame detector and construct accurate test conditions. The outer side of the light source assembly is rotatably connected to the inner side of the light box, and the light source assembly is linearly arranged along the central axis of the light box. The light source assembly includes a lamp shade, a searchlight is fixedly connected to the inner side of the lamp shade, a roller is fixedly connected to the outer side of the lamp shade. The number of light source assemblies is five. Among them, the searchlights in the light source assembly are a red light, an incandescent lamp, a xenon lamp, a gas discharge lamp, and an LED lamp in sequence. By simulating light sources with different spectral characteristics and light intensities, the sensitivity and anti-interference ability of the flame detector can be tested;

[0006] Cleaning component, the cleaning component is located inside the light box, a driving motor is fixedly connected to the outside of the light box, the output end of the driving motor is fixedly connected to a lead screw, the outer wall of the lead screw is threadedly connected to the top of the cleaning component, the cleaning component includes a moving seat, a telescopic cylinder is fixedly connected to the outside of the moving seat, the output end of the telescopic cylinder is fixedly connected to a sliding plate, a fixing frame is fixedly connected to the bottom of the sliding plate, guide rods are slidably connected to both sides of the fixing frame, the bottom ends of the guide rods are fixedly connected to a mounting frame, a rotating shaft is rotatably connected to the inside of the mounting frame, rubber pressing wheels are fixedly connected to both sides of the rotating shaft, a rubber plate is rotatably connected to the outer wall of the rotating shaft, a torsion spring is fixedly connected to the inside of the rubber plate, compression springs are fixedly connected to both sides of the top of the mounting frame. The cleaning component can clean the lamp shade, prevent the performance evaluation of the detector from being interfered by light fluctuations, and ensure that the test data accurately reflects the true level of the detector.

[0007] Preferably, the outside of the mounting table is rotatably connected to the inside of the sliding adjustment seat, a scale disk is fixedly connected to the outside of the mounting table, a locking bolt is threadedly connected to the bottom of the mounting table, the outside of the roller is rotatably connected to the inside of the light box, and both sides of the lead screw are rotatably connected to the inside of the light box. When the locking bolt is rotated and inserted into the hole opened on the surface of the horizontal movement guide rail, the sliding adjustment seat can be limited.

[0008] Preferably, the inner wall of the moving seat is slidably connected to the top of the inner wall of the light box, and the inner wall of the moving seat is threadedly connected to the outer wall of the lead screw. At this time, the driving motor is started, and the driving motor drives the lead screw to rotate, so that the cleaning component moves in the light box.

[0009] Preferably, the outside of the sliding plate is slidably connected to the outside of the moving seat, the top ends of the compression springs are fixedly connected to the bottom of the fixing frame. When the rubber pressing wheel contacts the roller, at this time, the fixing frame slides downward along the surface of the guide rod and approaches the mounting frame, forcing the compression springs to be compressed. At this time, under the elastic force of the compression springs, the rubber pressing wheel can be pressed against the surface of the roller.

[0010] Preferably, the side of the torsion spring away from the rubber plate is fixedly connected to the inside of the mounting frame, the outer wall of the rubber pressing wheel contacts the outer wall of the roller. When the rubber pressing wheel is pressed against the surface of the roller, the motor on the outside of the mounting frame drives the rotating shaft to rotate, so that the rotating shaft can drive the rubber pressing wheel to rotate together, and then drive the whole light source component to rotate.

[0011] Preferably, a connecting plate is fixedly connected to the bottom of the fixing frame, and a pressing roller is rotatably connected to the bottom of the connecting plate. As the fixing frame moves downward, the connecting plate drives the pressing roller to move downward synchronously.

[0012] Preferably, the outer wall of the pressure roller is in rolling connection with the outer side of the rubber plate, and the outer wall of the fixed frame is in sliding connection with the inner wall of the mounting frame. When the connecting plate drives the pressure roller to move downward synchronously, the pressure roller rolls along the outer side of the rubber plate and presses the rubber plate downward, causing it to deflect and contact the surface of the lampshade.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention fixes the flame detector by setting the mounting table. By setting the horizontal movement guide rail, the sliding adjustment seat can move on the surface of the frame, thereby realizing the adjustment of the distance between the flame detector and the light source. The servo motor can drive the mounting table to rotate, thereby realizing the angle adjustment of the flame detector, and the response performance of the flame detector at different detection angles can be analyzed, which is used to test the wide-angle performance and blind area range of the detector. The dial can be used to judge the deflection angle of the mounting table relative to the sliding adjustment seat, and the scale line opened on the surface of the horizontal movement guide rail can be used to judge the distance between the sliding adjustment seat and the light source. When the rotation locking bolt is inserted into the hole opened on the surface of the horizontal movement guide rail, the sliding adjustment seat can be limited.

[0015] 2. The present invention sets a cleaning component. After long-term use, when dust adheres to the outer side of the lampshade, the driving motor is started at this time. The driving motor drives the lead screw to rotate, so that the cleaning component moves in the lamp box, and thus the position of the cleaning component can be adjusted to clean the lampshade, preventing the interference of light fluctuations on the performance evaluation of the detector and ensuring that the test data accurately reflects the true level of the detector.

[0016] 3. The present invention sets a compression spring. When the rubber pressure wheel contacts the roller, the fixed frame slides downward along the surface of the guide rod and approaches the mounting frame, forcing the compression spring to be compressed. At this time, under the elastic force of the compression spring, the rubber pressure wheel can be pressed tightly against the surface of the roller. Subsequently, the motor on the outer side of the mounting frame drives the rotating shaft to rotate, so that the rotating shaft drives the rubber pressure wheel to rotate together, and then drives the overall rotation of the light source component, so as to facilitate the wiping of the lampshade by the rubber plate.

[0017] 4. The present invention sets a rubber plate. As the fixed frame moves downward, the connecting plate drives the pressure roller to move downward synchronously. At this time, the pressure roller rolls along the outer side of the rubber plate and presses the rubber plate downward, causing it to deflect and contact the surface of the lampshade. At this time, the torsion spring is twisted by force. At this time, as the lampshade rotates, the rubber plate and the surface of the lampshade slide relative to each other, and the cleaning process of the lampshade can be completed, ensuring the stability of the light intensity, uniformity and propagation direction of the light emitted by the searchlight, and creating a constant illumination environment for the flame detector test.

[0018] 5. The present invention provides a light source assembly, and adjusts the illumination intensity of the searchlight through a light source control box. The number of the light source assemblies is five. Among them, the searchlights in the light source assembly are a red light, an incandescent lamp, a xenon lamp, a gas discharge lamp, and an LED lamp in sequence. The on / off of the five light sources is controlled by switching the switch of the light source control box to provide a single light source type and test whether the flame detector responds to this light source. For a single light source, the light intensity is adjusted to 0W, 20W, 40W, 50W, 75W, and 100W respectively through the knob of the light source control box to test whether the flame detector responds to the light source of this intensity. The frequency of the light source is adjusted to 0Hz, 5Hz, 10Hz, 20Hz, 30Hz, and 50Hz respectively through the knob of the light source control box to test whether the flame detector responds to the light source of this frequency. Through the light intensity and frequency knobs of the light source control box, the response performance of the flame detector under light sources of different intensities and different frequencies is tested to judge the false alarm level of the flame detector. By simulating light sources with different spectral characteristics and light intensities, the sensitivity and anti-interference ability of the flame detector can be tested.

The servo motor 4 can drive the mounting table 5 to rotate, thereby realizing the angle adjustment of the flame detector, and the response performance of the flame detector at different detection angles can be analyzed, which is used to test the wide-angle performance and blind area range of the detector. Among them, the dial 6 can be used to judge the deflection angle of the mounting table 5 relative to the sliding adjustment seat 3, and the scale line provided on the surface of the horizontal moving guide rail 2 can be used to judge the distance between the sliding adjustment seat 3 and the light source. When the locking bolt 7 is rotated and inserted into the hole provided on the surface of the horizontal moving guide rail 2, the sliding adjustment seat 3 can be limited.

[0031] The light source assembly 12 is used to simulate a complex and diverse interference light source environment for the test of the flame detector and construct accurate test conditions. The outer side of the light source assembly 12 is rotatably connected to the inner side of the light box 8, and the light source assemblies 12 are linearly arranged along the central axis of the light box 8. The light source assembly 12 includes a lamp shade 121. A searchlight 122 is fixedly connected to the inner side of the lamp shade 121. A roller 123 is fixedly connected to the outer side of the lamp shade 121. The light source control box outside the frame 1 is electrically connected to the searchlight 122 in the light source assembly 12. The illumination intensity of the searchlight 122 can be adjusted through the light source control box. The number of the light source assemblies 12 is five. The searchlights 122 in the light source assemblies 12 are a red light, an incandescent lamp, a xenon lamp, a gas discharge lamp, and an LED lamp in sequence. By simulating light sources with different spectral characteristics and light intensities, the sensitivity and anti-interference ability of the flame detector can be tested;

[0032] The cleaning assembly 11 is located inside the light box 8. A driving motor 9 is fixedly connected to the outside of the light box 8. The output end of the driving motor 9 is fixedly connected to a lead screw 10. The outer wall of the lead screw 10 is threadedly connected to the top of the cleaning assembly 11. The cleaning assembly 11 includes a moving seat 111. A telescopic cylinder 113 is fixedly connected to the outside of the moving seat 111. The output end of the telescopic cylinder 113 is fixedly connected to a sliding plate 112. A fixing frame 114 is fixedly connected to the bottom of the sliding plate 112. Guide rods 115 are slidably connected to both sides of the fixing frame 114. The bottom ends of the guide rods 115 are fixedly connected to a mounting frame 116. A rotating shaft 118 is rotatably connected to the inside of the mounting frame 116. Rubber pressing wheels 102 are fixedly connected to both sides of the rotating shaft 118. A rubber plate 101 is rotatably connected to the outer wall of the rotating shaft 118. A torsion spring 119 is fixedly connected to the inside of the rubber plate 101. Compression springs 117 are fixedly connected to both sides of the top of the mounting frame 116. When the cleaning assembly 11 is directly above the lamp shade 121, the telescopic cylinder 113 outside the moving seat 111 extends at this time, so that the sliding plate 112 drives the fixing frame 114 to move downward. At the same time, the fixing frame 114 drives the mounting frame 116 to move downward as a whole through the compression spring 117. When the rubber pressing wheel 102 contacts the roller 123, the fixing frame 114 slides downward along the surface of the guide rod 115 at this time and approaches the mounting frame 116, forcing the compression spring 117 to be compressed. At this time, under the elastic force of the compression spring 117, the rubber pressing wheel 102 can be pressed against the surface of the roller 123. Subsequently, the motor outside the mounting frame 116 drives the rotating shaft 118 to rotate, so that the rotating shaft 118 drives the rubber pressing wheel 102 to rotate together, and then drives the whole light source assembly 12 to rotate, so as to facilitate the rubber plate 101 to wipe the lamp shade 121.

[0033] The inner wall of the moving seat 111 is slidably connected to the top of the inner wall of the light box 8. The inner wall of the moving seat 111 is threadedly connected to the outer wall of the lead screw 10. The outside of the sliding plate 112 is slidably connected to the outside of the moving seat 111. The top end of the compression spring 117 is fixedly connected to the bottom of the fixed frame 114. The side of the torsion spring 119 away from the rubber plate 101 is fixedly connected to the inside of the mounting frame 116. The outer wall of the rubber pressing wheel 102 is in contact with the outer wall of the roller 123. The bottom of the fixed frame 114 is fixedly connected with a connecting plate 103. The bottom of the connecting plate 103 is rotatably connected with a pressing roller 104. The outer wall of the pressing roller 104 is in rolling connection with the outside of the rubber plate 101. The outer wall of the fixed frame 114 is slidably connected to the inner wall of the mounting frame 116. As the fixed frame 114 moves downward, the connecting plate 103 drives the pressing roller 104 to move downward synchronously. At this time, the pressing roller 104 rolls along the outside of the rubber plate 101 and presses the rubber plate 101 downward, causing it to deflect and contact the surface of the lamp cover 121. At this time, the torsion spring 119 is torsionally stressed. At this time, as the lamp cover 121 rotates, the rubber plate 101 slides relative to the surface of the lamp cover 121, and the cleaning process of the lamp cover 121 can be completed, ensuring the stability of the light intensity, uniformity and propagation direction of the light emitted by the searchlight 122, and creating a constant lighting environment for the flame detector test.

[0034] Working principle: When in use, flame detectors of different specifications can be fixed on the mounting table 5 by bolts. The light source control box outside the frame 1 is electrically connected to the searchlight 122 in the light source assembly 12. The light intensity of the searchlight 122 can be adjusted through the light source control box. The number of light source assemblies 12 is five. Among them, the searchlights 122 in the light source assembly 12 are a red light, an incandescent lamp, a xenon lamp, a gas discharge lamp, and an LED lamp in sequence. By simulating light sources with different spectral characteristics and light intensities, the sensitivity and anti-interference ability of the flame detector can be tested;

[0035] By setting the horizontal movement guide rail 2, the sliding adjustment seat 3 can move on the surface of the frame 1, thereby realizing the adjustment of the distance between the flame detector and the light source. The servo motor 4 can drive the mounting table 5 to rotate, thereby realizing the angle adjustment of the flame detector, and the response performance of the flame detector at different detection angles can be analyzed, which is used to test the wide-angle performance and blind area range of the detector. Among them, the dial 6 can be used to judge the deflection angle of the mounting table 5 relative to the sliding adjustment seat 3, and the scale line provided on the surface of the horizontal movement guide rail 2 can be used to judge the distance between the sliding adjustment seat 3 and the light source. When the rotation locking bolt 7 is inserted into the hole provided on the surface of the horizontal movement guide rail 2, the sliding adjustment seat 3 can be limited.

[0036] Gradually control the lighting and extinguishing of five light sources by switching the switch of the light source control box, providing a single light source type, and testing whether the flame detector responds to this light source; for a single light source, adjust the light intensity to 0W, 20W, 40W, 50W, 75W, and 100W respectively through the knob of the light source control box, and test whether the flame detector responds to the light source of this intensity; adjust the frequency of the light source to 0Hz, 5Hz, 10Hz, 20Hz, 30Hz, 50Hz respectively through the knob of the light source control box, and test whether the flame detector responds to the light source of this frequency. Through the light intensity and frequency knobs of the light source control box, test the response performance of the flame detector under light sources of different intensities and frequencies to judge the false alarm level of the flame detector;

[0037] The light source control box controls the light source to turn on the red light source, adjusts the light intensity to 50W, and adjusts the frequency to 10Hz. By moving the flame detector, analyze its response time at different distances. The mounting table 5 supports 360° rotation. The light source control box controls the light source to turn on the red light source, adjusts the light intensity to 50W, and adjusts the frequency to 10Hz. By adjusting the detection angle of the mounting table 5, analyze the response performance of the flame detector at different detection angles to test the wide-angle performance and blind area range of the detector.

[0038] After long-term use, when dust adheres to the outer side of the lamp shade 121, start the drive motor 9 at this time. The drive motor 9 drives the lead screw 10 to rotate, so that the cleaning component 11 moves in the lamp box 8, and thus the position of the cleaning component 11 can be adjusted to clean the lamp shade 121, preventing the interference of light fluctuations on the performance evaluation of the detector and ensuring that the test data accurately reflects the true level of the detector;

[0039] During cleaning, when the cleaning component 11 is directly above the lamp shade 121, the telescopic cylinder 113 on the outer side of the moving seat 111 extends at this time, so that the sliding plate 112 drives the fixed frame 114 to move downward. At the same time, the fixed frame 114 drives the mounting frame 116 to move downward as a whole through the compression spring 117. When the rubber pressing wheel 102 contacts the roller 123, the fixed frame 114 slides downward along the surface of the guide rod 115 at this time and approaches the mounting frame 116, forcing the compression spring 117 to be compressed. At this time, under the elastic force of the compression spring 117, the rubber pressing wheel 102 can be pressed tightly against the surface of the roller 123. Subsequently, the motor on the outer side of the mounting frame 116 drives the rotating shaft 118 to rotate, so that the rotating shaft 118 drives the rubber pressing wheel 102 to rotate together, and then drives the entire light source assembly 12 to rotate, so as to facilitate the rubber plate 101 to wipe the lamp shade 121.

[0040] During this process, as the fixing frame 114 moves downward, the connecting plate 103 drives the pressure roller 104 to move downward synchronously. At this time, the pressure roller 104 rolls along the outer side of the rubber plate 101 and presses the rubber plate 101 downward, causing it to deflect and contact the surface of the lamp cover 121. At this time, the torsion spring 119 is stressed and twisted. At this time, as the lamp cover 121 rotates, the rubber plate 101 slides relative to the surface of the lamp cover 121, and the cleaning process of the lamp cover 121 can be completed, ensuring the stability of the light intensity, uniformity and propagation direction of the light emitted by the searchlight 122, and creating a constant illumination environment for the flame detector test.
