Description

Technical Field

[0001] The invention relates to the technical field of flame detection, and in particular to a flame detection control device. Background Art

[0002] A flame detector, also known as a photosensitive fire detector, is a fire detector used to respond to the optical characteristics of a fire, that is, to detect the light intensity of the burning flame and the flickering frequency of the flame. According to the optical characteristics of the flame, there are three types of flame detectors used: one is an ultraviolet detector that is sensitive to the shorter wavelength ultraviolet radiation in the flame; the other is an infrared detector that is sensitive to the longer wavelength infrared radiation in the flame; the third is an ultraviolet / infrared hybrid detector that simultaneously detects the shorter wavelength ultraviolet and longer wavelength infrared in the flame.

[0003] The current flame detection control device is found to have at least the following technical problems:

[0004] First, traditional flame detectors are often not flexible enough in terms of angle adjustment, and it is difficult to accurately adjust the detection angle according to the actual environment and needs, resulting in detection blind spots in some areas, reducing the accuracy and comprehensiveness of fire detection.

[0005] Second, at the same time, existing devices perform poorly in the function of moving the detector's position, cannot effectively expand the detection range, and are difficult to adapt to complex and changing monitoring scenarios, affecting the efficiency and reliability of fire detection. In terms of installation and disassembly, traditional devices are usually complicated to operate, time-consuming and labor-intensive, and are not conducive to rapid maintenance or replacement of detectors.

[0006] In summary, in order to improve the effect and efficiency of flame detection and ensure the safety of personnel and property, there is an urgent need for a flame detection control device that can flexibly adjust the angle and position, is easy to install and disassemble, and has a stable structure.

The mounting block is locked so that the fixings on the flame detector can be separated from the mounting block, which is convenient for separate maintenance or replacement of the flame detector. When the flame detector needs to be installed, the operator pushes the locking rod to compress the spring. At this time, the fixings on the flame detector can be sleeved on the mounting block. After loosening the locking rod, the elastic resetting effect of the spring is used to reset the locking rod.

[0016] (III) Beneficial effects

[0017] 1.

[0019] 3. The operator pushes the locking rod to move the locking rod toward the baffle. At this time, the end of the locking rod is no longer inserted into the fixing groove of the mounting block, and the locking of the mounting block is released. In this way, the fixing part on the flame detector can be separated from the mounting block, which is convenient for separate maintenance or replacement of the flame detector. When the flame detector needs to be installed, the operator pushes the locking rod to compress the spring. At this time, the fixing part on the flame detector can be sleeved on the mounting block. After loosening the locking rod, the elastic reset effect of the spring is used to reset the locking rod. The end of the locking rod is inserted into the fixing groove to complete the locking of the mounting block, realize the quick connection and fixation of the flame detector and the slide bar, and improve the efficiency of installation and disassembly.

[0020] Four: The two limit rods are movable through the fixed rods on the connecting plate, which plays a good limiting role in the movement of the connecting plate and the two racks, ensuring that the racks maintain linear motion during the movement and accurately mesh with the gears, thereby stably and accurately adjusting the tilt angle of the flame detector.

[0021] Five: There are two fixing plates fixedly installed on the slide rail, each of which is provided with fixing holes. The slide rail can be firmly installed in the desired position through the fixing plates and fixing holes using bolts and other connectors to ensure the stability of the entire device during operation.

[0022] 6.

[0035] When a fire occurs, the flame will release a large amount of ultraviolet rays of a specific wavelength. The optical system of the flame detector 1 will collect these ultraviolet rays and focus them on the photoelectric sensor. After receiving the ultraviolet rays, the photoelectric sensor will generate an electrical signal. This electrical signal is amplified, processed and analyzed. If its intensity and characteristics are consistent with the ultraviolet characteristics generated by the flame, it will be determined that a fire has occurred and trigger a corresponding alarm or control action. The flame detector 1 is an existing mature technology and will not be described in detail here. When in use, the telescopic rod is moved by starting the cylinder 4, and the movement of the telescopic rod drives the fixed rod 52 to move, and the movement of the fixed rod 52 then drives the connecting plate 5 to move. The movement of the connecting plate 5 drives the two racks 51 to move synchronously. Since the two racks 51 are respectively meshed with the two gears 13, the movement of the racks 51 drives the gears 13 to rotate, so that the flame detector 1 rotates around the connecting shaft 12, thereby realizing the adjustment of the inclination angle of the flame detector 1, and the engagement of the racks 51 with the gears 13 can lock the adjusted position of the flame detector 1, ensuring that it maintains a stable inclination angle during operation, thereby improving the accuracy and adaptability of detection;

[0036] When the horizontal position of the flame detector 1 needs to be adjusted, the servo motor 72 is started to rotate the threaded rod 73, and the rotation of the threaded rod 73 drives the slide bar 8 to move along the length direction of the slide rail 7. The movement of the slide bar 8 drives the flame detector 1 to move, which can expand the detection range of the flame detector 1, so that it can cover the monitoring area more comprehensively, and improve the efficiency and reliability of fire detection;

[0037] When the flame detector 1 needs to be disassembled, the operator pushes the locking rod 6 so that the locking rod 6 moves closer to the baffle 21. At this time, the end of the locking rod 6 is no longer inserted into the fixing groove 82 at the mounting block 81, and the locking of the mounting block 81 is released. In this way, the fixing part 3 on the flame detector 1 can be separated from the mounting block 81, which is convenient for separate maintenance or replacement of the flame detector 1. When the flame detector 1 needs to be installed, the operator pushes the locking rod 6 so that the spring 62 is compressed. At this time, the fixing part 3 on the flame detector 1 can be sleeved on the mounting block 81. After loosening the locking rod 6, the elastic reset effect of the spring 62 is used to reset the locking rod 6. The end of the locking rod 6 is inserted into the fixing groove 82 to complete the locking of the mounting block 81, and the flame detector 1 and the slide bar 8 are quickly connected and fixed, which improves the efficiency of installation and disassembly.

[0038] The two limiting rods 22 are movable through the fixed rod 52 on the connecting plate 5, which plays a good limiting role in the movement of the connecting plate 5 and the two racks 51, ensuring that the racks 51 maintain linear motion during the movement and precisely mesh with the gear 13, thereby stably and accurately adjusting the tilt angle of the flame detector 1;

[0039] Two fixing plates 74 are fixedly mounted on the slide rail 7, and each fixing plate 74 is provided with a fixing hole 75. The slide rail 7 can be firmly mounted at a desired position through the fixing plates 74 and the fixing holes 75 using bolts and other connecting parts to ensure the stability of the entire device during operation.

[0040] Working principle:

[0041] The first step is that when a fire occurs, the flame will release a large amount of ultraviolet rays of a specific wavelength. The optical system of the flame detector 1 will collect these ultraviolet rays and focus them on the photoelectric sensor. After receiving the ultraviolet rays, the photoelectric sensor will generate an electrical signal. This electrical signal is amplified, processed and analyzed. If its intensity and characteristics are consistent with the ultraviolet characteristics generated by the flame, it will be determined that a fire has occurred and trigger a corresponding alarm or control action. The flame detector 1 is an existing mature technology and will not be described in detail here. When in use, the telescopic rod is moved by starting the cylinder 4, and the movement of the telescopic rod drives the fixed rod 52 to move, and the movement of the fixed rod 52 then drives the connecting plate 5 to move. The movement of the connecting plate 5 drives the two racks 51 to move synchronously. Since the two racks 51 are respectively engaged with the two gears 13, the movement of the racks 51 drives the gears 13 to rotate, so that the flame detector 1 rotates around the connecting shaft 12, thereby realizing the adjustment of the inclination angle of the flame detector 1, and the engagement of the racks 51 with the gears 13 can lock the adjusted position of the flame detector 1, ensuring that it maintains a stable inclination angle during operation, thereby improving the accuracy and adaptability of detection.

[0042] In the second step, when the horizontal position of the flame detector 1 needs to be adjusted, the servo motor 72 is started to rotate the threaded rod 73. The rotation of the threaded rod 73 drives the slide bar 8 to move along the length direction of the slide rail 7. The movement of the slide bar 8 in turn drives the flame detector 1 to move, which can expand the detection range of the flame detector 1, enabling it to cover the monitoring area more comprehensively, thereby improving the efficiency and reliability of fire detection.

[0043] In the third step, when the flame detector 1 needs to be disassembled, the operator pushes the locking rod 6 so that the locking rod 6 moves closer to the baffle 21, and the end of the locking rod 6 is no longer inserted into the fixing groove 82 at the mounting block 81, and the locking of the mounting block 81 is released, so that the fixing member 3 on the flame detector 1 can be separated from the mounting block 81, which is convenient for the separate maintenance or replacement of the flame detector 1. When the flame detector 1 needs to be installed, the operator pushes the locking rod 6 so that the spring 62 is compressed. At this time, the fixing member 3 on the flame detector 1 can be sleeved on the mounting block 81. After loosening the locking rod 6, the elastic reset effect of the spring 62 is used to reset the locking rod 6. The end of the locking rod 6 is inserted into the fixing groove 82 to complete the locking of the mounting block 81, and the flame detector 1 and the slide bar 8 are quickly connected and fixed, which improves the efficiency of installation and disassembly.

[0044] In the fourth step, the two limit rods 22 are movable through the fixed rod 52 on the connecting plate 5, which plays a good limiting role in the movement of the connecting plate 5 and the two racks 51, ensuring that the rack 51 maintains linear motion during the movement and accurately meshes with the gear 13, thereby stably and accurately realizing the adjustment of the tilt angle of the flame detector 1.

[0045] In the fifth step, two fixing plates 74 are fixedly installed on the slide rail 7, and each fixing plate 74 is provided with a fixing hole 75. The slide rail 7 can be firmly installed in the desired position through the fixing plates 74 and the fixing holes 75 using bolts and other connecting parts to ensure the stability of the entire device during operation.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
