TECHNICAL FIELD
[0001] The utility model relates to linear light beam smoke fire detector filter detection technical field especially relates to a linear light beam smoke fire detector filter detection device. BACKGROUND
[0002] When detecting the filter of the detector, a linear light beam smoke fire detector filter detection device is often used, which is a special equipment for detecting the performance of linear light beam smoke fire detector. By simulating the fire smoke environment, the sensitivity and response time of the detector are evaluated. The use of this device can ensure the accuracy and reliability of the detector, timely detect and handle fire hazards, improve fire safety level, and reduce personnel casualties and property losses.
[0003] The filter detection device of the linear light beam smoke fire detector mainly emits a light beam of a specific wavelength from the emitting end. The light beam passes through the monitored area and reaches the receiving end. The receiving end uses a filter to screen and filter the received light signal. Only the light with a wavelength matching the scattered light of the smoke particles is allowed to pass through, thereby effectively reducing the influence of environmental light and other interference factors on the detection result and improving the accuracy and reliability of fire detection.
[0004] In the prior art, the traditional detection method mainly focuses on the simple test of the overall alarm function of the detector, such as simulating the smoke environment to observe whether the detector alarms. However, the effective detection of the key performance indicators and filter capacity of the detector is ignored. In the actual operation process of the linear light beam smoke fire detector, the environmental factors are complex and changeable, such as dust, water vapor, light, and many other interference sources. The internal filter bears the responsibility of excluding these interferences and ensuring the accurate identification of smoke signals by the detector. The existing detection device cannot accurately simulate different degrees of smoke filter scenes, making it difficult to comprehensively and accurately evaluate the performance of the linear light beam smoke fire detector under various complex filter conditions. This leads to the fact that some detectors pass the regular detection, but in real fire smoke environment or scenes with more interferences, due to poor filter performance, the detector cannot respond to the smoke signal in time and accurately, resulting in false alarms, missed alarms, and other situations, which seriously affects the reliability of fire warning and brings great hidden dangers to life and property safety.

[0036] Reference Figs. 1-2 An embodiment provided by the utility model: a kind of linear light beam smoke fire detector filter detection device, including rack 1, can withstand the weight of each component inside and vibration and impact force generated in the process of operation, the inside of rack 1 is fixedly connected with fixed frame one 2, for accurate installation and fixed detection mechanism, detection mechanism is provided in the inside of rack 1, the outer wall of rack 1 left and right sides is provided with dismounting and installing mechanism, the outer wall of rack 1 left and right sides is provided with adjusting mechanism;
[0037] The detection mechanism comprises a disc fixing frame 3 for fixing and supporting a transmission shaft 5 and a rotating wheel 6, ensuring stable relative position and movement track during operation, and providing a basis for installation of a filter 11. The outer wall of the disc fixing frame 3 is fixedly connected with a driving assembly, which transmits power to the transmission shaft 5, thereby driving the whole detection mechanism to operate. The output end of the driving assembly is rotationally connected with the transmission shaft 5, so that the power of the driving assembly can be smoothly transmitted to the rotating wheel 6, realizing power transmission and conversion. The outer wall of the transmission shaft 5 is rotationally connected with the rotating wheel 6, which realizes power conversion and transmission through cooperation with the transmission shaft 5 and a belt 7. During rotation, the rotating wheel 6 can drive the coupled belt 7 to move, thereby transmitting power to a transmission shaft 8.
[0038] The outer wall of the rotating wheel 6 is coupled with the belt 7, the two ends of the belt 7 are connected with the rotating wheel 6 and the transmission shaft 8 respectively, and the power of the rotating wheel 6 is transmitted to the transmission shaft 8 through friction. The outer wall of the rotating wheel 6 is rotationally connected with the transmission shaft 8, which transmits the power of the rotating wheel 6 to a disc 10 and drives the disc 10 to rotate. The inner part of the transmission shaft 8 is fixedly connected with a protective cover 9, which protects the filter 11 and prevents dust and impurities from entering the detection area, avoids the harm caused by accidentally touching the high-speed rotating disc 10 and filter 11 during equipment operation, and rotationally connects the disc 10 in the inner space area of the protective cover 9, which carries the filter 11 and rotates under the drive of the transmission shaft 8, so that the filter 11 can filter light. During rotation, the disc 10 can drive the filter 11 to rotate in the protective cover 9, realizing switching and detection of different filters 11.
[0039] The inner part of the disc 10 is fixedly connected with the filter 11, which can selectively filter light and only allow light of a specific wavelength range to pass through, thereby realizing adjustment and detection of light received by a detector main body 12. The disc 10 is driven to rotate to meet different detection scenes and detection requirements. The outer wall of the rack 1 is fixedly connected with the detector main body 12 on the left and right sides. The outer wall of the transmission shaft 8 is fixedly connected to the top of the disc fixing frame 3. The dismounting and mounting mechanism comprises a mounting seat 13, which is a support component of the dismounting and mounting mechanism, provides a stable mounting basis for a knob 14, a connecting rod 15 and a fixed block 16, and is fixedly connected with the outer wall of the rack 1 to firmly mount the whole dismounting and mounting mechanism on the rack 1, ensuring that it will not shake or displace during operation.
[0040] The outer wall of the mounting seat one 13 is fixedly connected with a knob 14, which can convert the manual operation of the operator into mechanical movement. By rotating the knob 14, the connecting rod 15 is driven to move, thereby realizing the position adjustment of the fixed block 16, and further controlling the sliding of the ring block one 17, finally realizing the disassembly and installation of the detection mechanism. The outer wall of the knob 14 is fixedly connected with the connecting rod 15, which can convert the rotary motion of the knob 14 into the linear motion or swing of the fixed block 16. When the knob 14 rotates, the connecting rod 15 will move with it and drive the fixed block 16 to slide on the ring block one 17, thereby realizing the position adjustment and disassembly and installation operation of the related components.
[0041] The outer wall of the connecting rod 15 is fixedly connected with the fixed block 16, which can slide on the inner wall of the ring block one 17 under the driving of the connecting rod 15, thereby pushing the ring block one 17 to move correspondingly and realizing the fixation and loosening of the detection mechanism. The position adjustment accuracy of the fixed block 16 directly affects the effect and stability of disassembly and installation. The outer wall of the mounting seat one 13 is fixedly connected with the outer wall of the rack 1 on the left and right sides.
[0042] Referring to Figs. 3-4 The adjusting mechanism includes a motor 4, the outer portion of which is fixedly connected to the outer portion of the fixed frame one 2. The outer portion of the transmission shaft one 5 is rotatably connected to the inner portion of the motor 4. The outer wall of the fixed block 16 is slidingly connected with the ring block one 17, which can slide along the outer wall of the rack 1 under the pushing of the fixed block 16, thereby realizing the approaching or moving away operation of the detection mechanism. Through cooperation with the ring block two 20, the ring block one 17 can also realize a certain degree of positioning and limiting function, ensuring the accuracy and stability of the disassembly and installation process. The inner portion of the ring block one 17 is provided with a vertical groove 18 in the space area, which provides a sliding track for the fixed block 16, so that the fixed block 16 can stably slide in the ring block one 17. The existence of the vertical groove 18 limits the movement direction of the fixed block 16, ensuring that it moves within the predetermined track, thereby realizing the accurate control of the ring block one 17.
[0043] The outer wall of the ring block one 17 is fixedly connected with a connecting ring 19, which is used for connecting external operating tools or equipment to operate the ring block one 17, for example, during disassembly or installation, the operator can pull or rotate the connecting ring 19 to drive the ring block one 17 to move, so as to realize the disassembly and installation of the detection mechanism. The outer wall of the ring block one 17 is fixedly connected with a ring block two 20, which cooperates with the ring block one 17 to realize the positioning and limiting functions of the detection mechanism. When the ring block one 17 is pushed by the fixed block 16 and slides to a certain position, the ring block two 20 can limit the ring block one 17 through the limiting transverse groove 21 to prevent it from sliding too much, thereby ensuring the safety and stability of the disassembly and installation process. The middle space area of the ring block two 20 is provided with a limiting transverse groove 21. When the ring block one 17 slides close to the ring block two 20, the limiting transverse groove 21 can limit the ring block one 17 to prevent it from continuing to slide, so as to form a stable relative positional relationship between the ring block one 17 and the ring block two 20.
[0044] Referring to Figs. 5-6 The adjusting mechanism includes a mounting seat two 22, which is a support component of the adjusting mechanism and provides a stable mounting base for the connecting column 24, the connecting rod 25 and the follower rod 26. The adjusting mechanism is firmly mounted on the rack 1 through the fixed connection of the bottom with the ring block two 20, so as to ensure that it will not shake or displace during work. At the same time, the mounting seat two 22 also serves as a support point of the connecting column 24 to limit the movement range of the connecting column 24 and ensure the stability and precision of the adjusting mechanism. The mounting seat two 22 is provided with mounting holes 23 on the left and right sides of the inside to install the connecting rod 25. The components are fixed on the mounting seat two 22 through bolt, pin and other connection methods. The existence of the mounting hole 23 makes the installation and disassembly of the components more convenient and fast, and also ensures the accurate position and stability of the components on the mounting seat two 22.
[0045] The bottom of the mounting seat two 22 is fixedly connected to the top of the ring block two 20. The outer wall of the mounting seat two 22 is fixedly connected with a connecting column 24, which can rotate or swing under the support of the mounting seat two 22, thereby driving the connecting rod 25 and the follower rod 26 to move. Through the connecting column 24, the position adjustment and limiting functions of the detection mechanism can be realized to ensure that it is in the correct position and state during work. The connecting column 24 is rotatably connected with a connecting rod 25 in the middle space area of the inside. Under the driving of the connecting column 24, the connecting rod 25 can rotate or swing, thereby transmitting the movement of the connecting column 24 to the movement of the connecting rod 25 to realize the position adjustment and operation functions of the detection mechanism, such as pushing, pulling, rotating, etc.
[0046] The space area in the interior of the connecting column 24 is rotationally connected with the follow-up rod 26, which can move together with the connecting rod 25 under the driving of the connecting column 24, and is connected or operated through the mounting groove 27 at the top, and the movement of the follow-up rod 26 can realize the auxiliary adjustment and operation function of the detection mechanism, such as limiting and locking, to ensure that it is in a stable and safe state during the working process. The top space area of the follow-up rod 26 is fixedly connected with the mounting groove 27 for mounting the detector main body 12, which ensures the accurate position and stability of the detector main body 12 on the follow-up rod 26. At the same time, the mounting groove 27 also facilitates the disassembly and replacement of the detector main body 12, improving the maintainability and flexibility of the adjustment mechanism.
[0047] Working principle: the motor 4 starts to work as a power source and transmits power output to the transmission shaft 5 rotationally connected thereto. The transmission shaft 5 starts to rotate under the power of the motor 4, driving the runner 6 rotationally connected to the outer wall on one side to operate. In the operating process of the runner 6, the power is transmitted to the transmission shaft 2 through the outer wall coupling connection of the belt 7 by using friction. The transmission shaft 2 starts to rotate after receiving the power. Since the protective cover 9 is fixedly connected inside the transmission shaft 2, its rotation drives the protective cover 9 to rotate. The disc 10 rotationally connected in the interior space area of the protective cover 9 also starts to rotate under the driving of the transmission shaft 2. The light filter 11 fixedly connected inside the disc 10 rotates with the disc 10. The light filter 11 selectively filters light, allowing only light of a specific wavelength range to pass through, realizing the adjustment and detection of the light received by the detector main body 12 to meet different detection scenes and detection requirements. In the whole process, the fixed frame 2 inside the rack 1 provides an accurate installation and fixing basis for the motor 4. The disc fixed frame 3 fixes and supports the transmission shaft 5, the runner 6, ensuring that the relative position and motion track remain stable during the working process, and providing a basis for the installation of the light filter 11.
[0048] The operator rotates the knob 14 on the outer wall of the mounting seat 13 on one side. The rotation of the knob 14 drives the connecting rod 15 fixedly connected thereto to move, which promotes the fixed block 16 to slide along the vertical groove 18 in the inner wall of the ring block 17, thereby pushing the ring block 17 to slide along the outer wall of the rack 1. In the sliding process, the operator can assist the operation by pulling or rotating the connecting ring 19 on the outer wall of the ring block 17. When the ring block 17 slides close to the ring block 20, the limiting transverse groove 21 of the ring block 20 limits the ring block 17. The sliding of the ring block 17 under the pushing of the fixed block 16 realizes the approach or away operation of the detection mechanism, and finally achieves the disassembly and installation of the detection mechanism.
[0049] The mounting seat two 22 is fixedly connected with the ring block two 20 on the frame 1 through the bottom as a supporting part of the adjusting mechanism, the mounting holes 23 on the left and right sides in the mounting seat two 22 are used for mounting the connecting rod 25, the connecting column 24 is fixed in the space area of the outer wall of the mounting seat two 22 and can rotate or swing under the support of the mounting seat two 22, when the connecting column 24 rotates or swings, the connecting rod 25 and the follower rod 26 connected with the connecting column 24 rotate are driven to move, the movement of the connecting rod 25 can adjust and operate the position of the detector main body 12, the follower rod 26 moves following the connecting rod 25, the mounting slot 27 on the top of the follower rod 26 is used for mounting the detector main body 12, the movement of the follower rod 26 can assist in adjusting and operating the detector main body 12, such as limiting, locking and the like, so as to realize the adjustment and limiting of the position of the detector main body 12 and ensure that the detector main body 12 is in the correct position and state in the working process.
