Description

Technical Field

[0001] The present application relates to the technical field of fire warning, and in particular to a multifunctional integrated composite fire warning device. Background Art

[0002] Currently common fire warning equipment mainly includes smoke detectors, temperature detectors and flame detectors. These devices sense environmental changes through different sensing mechanisms and trigger an alarm once the preset threshold is reached.

[0003] Among them, the smoke detector mainly includes a housing, a light source for emitting a light beam, a photoelectric receiver for receiving scattered light, and a signal processing unit. The smoke detector can detect smoke particles generated by an initial fire, but it is difficult to accurately distinguish between fire smoke particles and non-fire interferences, such as small insects, dust, and other interferences. Especially for places with many small flies, spiders and other insects such as barns, farmers' markets or fruit and vegetable stores, they are easily attracted by the flashing indicator light on the detector and enter the detector, interfering with the detection of the detector and causing false alarms. The temperature detector mainly includes a housing, a thermistor for sensing temperature changes, and a signal conversion circuit that converts the physical changes produced by the thermistor into an electrical signal. It uses temperature changes to warn of fires and is particularly sensitive to fire identification in high temperature environments. However, the reaction time is long, which is not conducive to the early detection of fires, and it is easily affected by dust coverage, resulting in delayed warnings. The flame detector mainly includes a housing, a flame sensor module for detecting flames, various photoelectric components, a circuit board, a signal processing circuit and a sealed detection window. The flame detector warns of fires based on the intensity of flame radiation, and it is easily affected by obstructions.

[0004] However, although the various existing fire warning devices have their own characteristics, traditional fire warning devices mostly rely on a single type of detector, lack comprehensive judgment capabilities, are difficult to adapt to the complex and changeable actual environmental needs, and cannot cover the characteristics of different types of fires, which limits the accuracy and reliability of the warning. They are also easily interfered by external non-fire factors, delaying warnings, resulting in untimely rescue and unnecessary property losses, or easily generating false alarms, disturbing people's normal life order, and causing users to lose their due vigilance against warning signals. Summary of the invention

[0005] In order to improve the comprehensive judgment ability of the fire warning device, adapt to the complex and changeable actual environmental requirements, and at the same time improve the accuracy and reliability of the warning, the present application provides a multifunctional integrated composite fire warning device.

[0006] The present application provides a multifunctional integrated composite fire warning device, which adopts the following technical solutions: A multifunctional integrated composite fire warning device, comprising: A housing, wherein a plurality of sensing channels are arranged along the circumference of the housing, and a detector integrated module is built into the housing, wherein the detector integrated module includes a smoke detector, a flame detector and a temperature detector; The main control unit is connected to the detector integrated module and is responsible for data collection, analysis and processing, and the sending of control instructions; Communication interface, connected to the main control unit, supports wireless communication protocol, and is also connected to the cloud server or other terminal devices; The self-cleaning and dust-proof mechanism is arranged between the outer shell and the detector integrated module, and includes a self-cleaning component and a dust-proof component. The self-cleaning and dust-proof mechanism has an anti-false alarm mode and an automatic cleaning mode. When the self-cleaning and dust-proof mechanism is in the anti-false alarm mode, the dust-proof component is started; when the self-cleaning and dust-proof mechanism is in the automatic cleaning mode, both the self-cleaning component and the dust-proof component are started.

[0007] By adopting the above technical solution, smoke detectors, flame detectors and temperature detectors respectively monitor the concentration of smoke particles in the air, the intensity of flame radiation and the changes in the ambient temperature, and ensure all-round environmental monitoring by collecting data. The main control unit is responsible for collecting data from the detector integrated module and analyzing and processing the data through the built-in algorithm. The main control unit determines whether the warning threshold is reached based on the analysis results. Once the fire signal is confirmed, the main control unit will send a control instruction to trigger the warning mechanism, including starting the alarm and transmitting the warning information to the cloud server or other terminal devices in real time through the communication interface, so as to realize remote monitoring and management, and thus quickly respond to the fire. When the self-cleaning dustproof mechanism is in the anti-false alarm mode, the dustproof component is started to prevent non-fire factors such as dust and small insects from entering the detector integrated module, thereby reducing false alarms caused by external interference. When the cleaning and dustproof mechanism is in automatic cleaning mode, both the self-cleaning component and the dustproof component are started, and the dustproof component cooperates with the self-cleaning component to remove dust and impurities on the detector integrated module, keep the detector integrated module clean, and improve the accuracy of data collection; wherein, through the cooperation of the detector integrated module, the main control unit, the communication interface, the self-cleaning and dustproof mechanism, etc., it can quickly respond to fire signals in the early stage of fire, improve the comprehensive judgment ability of the fire warning device, adapt to the complex and changeable actual environmental requirements, and at the same time improve the accuracy and reliability of the warning, and gain precious time for personnel evacuation and fire extinguishing; and the self-cleaning and dustproof mechanism reduces the maintenance workload of the fire warning device, cleans the fire warning device regularly and in time, reduces unnecessary interference, reduces the false alarm rate, enables the fire warning device to provide more accurate and timely fire warnings, and improves the overall performance of the warning system.

[0008] Optionally, the dustproof component includes: A synchronous ring gear, rotatably connected to the interior of the housing; The dustproof net is fixedly mounted on the synchronous gear ring, and a plurality of the dustproof nets are provided. The plurality of dustproof nets are arranged in one-to-one correspondence with the plurality of sensing channels, and the dustproof nets are used to shield the corresponding sensing channels.

[0009] By adopting the above technical solution, when the self-cleaning dust-proof mechanism switches to the anti-false alarm mode and the dust-proof component is started, the synchronous gear ring starts to rotate and drives the dust-proof net to block the corresponding sensing channel. The dust-proof net only allows smoke particles or extremely small dust impurities to enter, thereby preventing most non-fire interference factors such as dust and small insects from entering the detector integrated module, protecting the detector integrated module from being contaminated and affected by impurities, reducing false alarms caused by external interference, and improving the accuracy and reliability of early warning; when the self-cleaning dust-proof mechanism switches to the automatic cleaning mode, the synchronous gear ring starts to rotate and drives the dust-proof net to temporarily open the corresponding sensing channel to allow the self-cleaning component to perform cleaning work, and then blocks it again.

[0010] Optionally, the self-cleaning component includes: A scraping component is provided on the housing and is used to scrape away impurities adhered to both sides of the dustproof net; A self-locking driving component is disposed between the housing and the synchronous gear ring, and is used to drive the synchronous gear ring to rotate and lock the position of the synchronous gear ring after rotation; A wiping component, arranged on the housing, and used for wiping the detection window of the flame detector; The timing controller is connected to the self-locking driving component and the wiping component and is used for regularly starting the self-locking driving component and the wiping component.

[0011] By adopting the above technical solution, the timing controller is connected to the self-locking driving component and the wiping component, and the self-locking driving component and the wiping component are automatically started according to the preset time interval, that is, the self-cleaning dustproof mechanism is switched to the automatic cleaning mode to realize regular automatic cleaning. When cleaning, the self-locking driving component first drives the synchronous gear ring to rotate, and the rotation of the synchronous gear ring causes the dustproof net to move accordingly, and cooperates with the scraping component to scrape off the impurities adhering to the dustproof net, thereby ensuring the permeability of the dustproof net and improving the response speed and accuracy of the detector; at the same time, in the automatic cleaning mode, the wiping component is started synchronously, and the wiping component is used to clean the detection window of the flame detector. Wipe to remove dust or impurities that may affect the detection effect, and maintain the high sensitivity and accuracy of the detector; through the coordinated action of the scraping component, the self-locking drive component, the wiping component, and the timing controller, the dust and impurities on the detection windows of the smoke detector and the flame detector can be removed simultaneously, maintaining the high sensitivity and accuracy of the detector integrated module, improving the performance of the early warning device, and reducing false alarms and missed alarms; at the same time, the self-locking drive component also has a locking function to ensure that the dustproof net can be stably locked for a long time to protect the sensing channel without power input after cleaning is completed, to prevent malfunction due to external vibration or airflow.

[0012] Optionally, a fan is provided in the housing, the fan is connected to a timing controller, a plurality of air ducts are provided on a side of the housing close to the thermistor of the temperature detector, and air outlets of the air ducts face the thermistor of the temperature detector.

[0013] By adopting the above technical solution, when the self-cleaning dustproof mechanism is switched to the automatic cleaning mode, the timing controller will start the fan. On the one hand, the fan can blow the impurities scraped off the dustproof net by the scraping component through the sensing channel to the outside of the shell; on the other hand, multiple air ducts are arranged on the side of the shell close to the thermistor of the temperature detector, and the air outlet of the air duct is directly facing the thermistor of the temperature detector. When the fan is started, the air duct will guide the airflow, and the airflow is guided to the vicinity of the thermistor of the temperature detector through the air duct, so that the impurities adhered to the thermistor of the temperature detector are blown away by the synergistic action of the fan and the air duct, so that the thermistor can subsequently sense the changes in ambient temperature more quickly, thereby improving the response speed of the thermistor of the temperature detector.

[0014] Optionally, the scraping component includes: An outer scraper is fixed to the outer shell, and a plurality of them are provided and correspond one to one with the plurality of dustproof nets; The inner scraper is fixed to the outer shell, and is provided in plurality and corresponds to the plurality of dustproof nets one by one.

[0015] By adopting the above technical scheme, the inner and outer sides of each dustproof net are respectively abutted against the inner scraper and the outer scraper to form a closed cleaning path. When the self-locking drive component drives the synchronous gear ring to rotate, multiple dustproof nets move synchronously with the synchronous gear ring. The movement of the dustproof net drives the inner scraper and the outer scraper abutting therewith to perform cleaning and scraping work, thereby scraping off dust, small insects and other impurities adhering to the dustproof net, ensuring the permeability of the dustproof net and improving the response speed and accuracy of the detector integrated module.

[0016] Optionally, the self-locking drive component includes: A drive shaft rotatably connected to the housing; The driving gear is fixedly sleeved on the driving shaft and meshes with the synchronous gear ring; A worm gear is fixedly sleeved on the driving shaft; A worm, rotatably connected to the housing and meshing with the worm wheel; The driving motor is arranged at one end of the worm and connected to the timing controller.

[0017] By adopting the above technical solution, when the self-cleaning dustproof mechanism enters the automatic cleaning mode, the timing controller sends a start signal to the drive motor, the drive motor starts to run and drives the worm to rotate, and then the worm drives the worm wheel to rotate, the rotation of the worm wheel will drive the drive shaft to rotate, the drive shaft drives the drive gear to rotate, and the drive ring gear rotates accordingly; when the drive motor stops running, the self-locking characteristics of the worm and the worm wheel enable the drive shaft and the synchronous ring gear to remain in the current position without power input, thereby reducing energy consumption, and at the same time ensuring that the dustproof net can be stably locked after cleaning is completed, preventing the dustproof net from malfunctioning due to external vibration or airflow, thereby improving the stability of the dustproof net in blocking dust in the sensing channel.

[0018] Optionally, the wiping component includes: A guide track is fixedly arranged on the outer side of the shell; A walking frame, slidably connected to the guide rail; A traveling wheel, rotatably connected to the traveling frame; The self-locking hub motor is arranged between the traveling wheel and the traveling frame and is connected to the timing controller; A rotating shaft is rotatably connected to the traveling frame, and a plurality of rotating shafts are arranged at intervals along the length direction of the traveling frame; A flexible wiping member is fixedly arranged at one end of the rotating shaft close to the detection window of the flame detector; A driven gear is fixedly sleeved on the outside of the rotating shaft, and a plurality of driven gears are meshed with each other; A driving gear is rotatably connected to the traveling frame, the driving gear is meshed with one of the driven gears, and a power motor is arranged at one end of the rotating shaft of the driving gear, and the power motor is connected to the timing controller.

[0019] By adopting the above technical solution, when the self-cleaning and dust-proof mechanism enters the automatic cleaning mode, the timing controller sends a start signal to the self-locking hub motor, the self-locking hub motor starts to operate, generates walking power, drives the walking wheel to rotate, and then the walking wheel drives the walking frame to move along the guide track, the movement of the walking frame drives the movement of the entire wiping component, and at the same time the power motor drives the driving gear to rotate, the driving gear synchronously drives multiple driven gears and the rotating shaft to rotate, the rotation of the rotating shaft drives the flexible wiping member to rotate, and the flexible wiping member contacts the detection window of the flame detector, thereby cleaning the dust and impurities on the surface of the detection window of the flame detector; wherein the wiping member can cover the entire area of ​​the detection window of the flame detector through the movement of the walking frame and the rotation of the flexible wiping member, ensuring the comprehensive cleaning of the detection window of the flame detector, and improving the sensitivity and accuracy of the flame detector; and when the detection window of the flame detector is cleaned, the self-locking hub motor stops running, and the self-locking characteristics of the self-locking hub motor keep the walking frame in the current position, ensuring that the wiping member can be stably locked after cleaning, and avoiding the wiping member from malfunctioning due to wind or vibration, resulting in the blocking of the detection window.

[0020] Optionally, the wiping component further includes: The wind collecting chamber is fixed on the traveling frame; The fan is arranged in the air collecting chamber and connected to the timing controller; The wind collecting channels are fixedly arranged in the wind collecting bin, and are provided in plurality and correspond one to one with the plurality of rotating shafts. The wind collecting channels are sleeved on the outer sides of the corresponding rotating shafts, and the rotating shafts are hollow inside and open at both ends.

[0021] By adopting the above technical scheme, when the self-cleaning and dust-proof mechanism enters the automatic cleaning mode, the timing controller sends a start signal to the fan, and the fan starts to run to generate suction. The operation of the fan forms a negative pressure in the air collecting bin and the air collecting channel. Since the air collecting channel is arranged on the outside of the rotating shaft, the rotating shaft is hollow inside and has openings at both ends, the dust scraped by the flexible wiper will be absorbed by the negative pressure generated by the fan into the hollow part of the rotating shaft, and then enter the air collecting bin through the air collecting channel, and finally be sucked into the fan and discharged to the outside; wherein, through the dual cleaning action of the fan and the flexible wiper, on the one hand, the detection window of the flame detector is fully cleaned to improve the sensitivity and accuracy of the flame detector, and on the other hand, the negative pressure generated by the fan can absorb the dust adhered to the flexible wiper and the dust scraped off, so that the flexible wiper is kept clean continuously.

[0022] Optionally, a plurality of pressing plates are provided between the air collecting channel and the flexible wiping member, the plurality of pressing plates correspond to a plurality of rotating shafts one by one, and the rotating shafts are rotatably connected to the corresponding pressing plates; A plurality of damping telescopic rods are arranged between the air collecting channel and the pressure plate, and a damping spring is sleeved on the outer side of the damping telescopic rod. The damping spring is in a compressed state and gives the pressure plate a force close to the detection window side of the flame detector.

[0023] By adopting the above technical solution, under the action of the damping telescopic rod and the damping spring, the pressure plate can drive the flexible wiping member to be close to the detection window of the flame detector, thereby improving the wiping effect of the flexible wiping member.

[0024] Optionally, a storage box is fixedly provided on the shell, and the storage box is located at one end of the guide track.

[0025] By adopting the above technical solution, the wiping component will enter the storage box when not in use. The storage box can prevent the wiping component from being easily exposed to external dust, especially the flexible wiping component from accumulating too much dust, thereby maintaining its cleaning effect and ensuring that the best cleaning effect can be provided when needed.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: When the self-cleaning and dust-proof mechanism is in the anti-false alarm mode, the dust-proof component is activated to prevent non-fire factors such as dust and small insects from entering the detector integrated module, thereby reducing false alarms caused by external interference; when the self-cleaning and dust-proof mechanism is in the automatic cleaning mode, both the self-cleaning component and the dust-proof component are activated, and the dust-proof component cooperates with the self-cleaning component to remove dust and impurities on the detector integrated module, thereby keeping the detector integrated module clean and improving the accuracy of data collection; wherein, through the coordinated action of the detector integrated module, the main control unit, the communication interface, the self-cleaning and dust-proof mechanism, etc., it is possible to quickly respond to fire signals at the early stage of a fire, improve the comprehensive judgment ability of the fire warning device, adapt to the complex and changeable actual environmental requirements, and at the same time improve the accuracy and reliability of the warning, thereby buying precious time for personnel evacuation and fire extinguishing; and the self-cleaning and dust-proof mechanism reduces the maintenance workload of the fire warning device, cleans the fire warning device regularly and in a timely manner, reduces unnecessary interference, reduces the false alarm rate, enables the fire warning device to provide more accurate and timely fire warnings, and improves the overall performance of the warning system; When the self-cleaning dust-proof mechanism switches to the anti-false alarm mode and the dust-proof component starts, the synchronous gear ring starts to rotate and drives the dust-proof net to block the corresponding sensing channel. The dust-proof net only allows smoke particles or extremely small dust impurities to enter, thereby preventing most non-fire interference factors such as dust and small insects from entering the detector integrated module, protecting the detector integrated module from being easily contaminated and affected by impurities, reducing false alarms caused by external interference, and improving the accuracy and reliability of early warning; when the self-cleaning dust-proof mechanism switches to the automatic cleaning mode, the synchronous gear ring starts to rotate and drives the dust-proof net to temporarily open the corresponding sensing channel so that the self-cleaning component can perform cleaning work, and then blocks it again; The scraping component, self-locking drive component, wiping component and timing controller in the self-cleaning component can simultaneously remove dust and impurities on the detection windows of smoke detectors and flame detectors, maintain the high sensitivity and accuracy of the detector integrated module, improve the performance of the early warning device, and reduce false alarms and missed alarms; at the same time, the self-locking drive component also has a locking function to ensure that the dustproof net can be stably locked for a long time to protect the sensing channel without power input after cleaning, to prevent malfunction due to external vibration or airflow; When the self-cleaning dustproof mechanism is switched to the automatic cleaning mode, the timing controller will start the fan.

[0036] The timing controller is connected to the self-locking driving component 412 and the wiping component 413, and automatically starts the self-locking driving component 412 and the wiping component 413 according to the preset time interval, that is, the self-cleaning dustproof mechanism 4 switches to the automatic cleaning mode to achieve regular automatic cleaning. When cleaning, the self-locking driving component 412 first drives the synchronous ring gear 421 to rotate, and the rotation of the synchronous ring gear 421 causes the dustproof net 422 to move accordingly, and cooperates with the scraping component 411 to scrape off the impurities adhering to the dustproof net 422, thereby ensuring the permeability of the dustproof net 422 and improving the response speed and accuracy of the detector.

[0037] At the same time, in the automatic cleaning mode, the wiping component 413 is started synchronously. The wiping component 413 is used to wipe the detection window 321 of the clean flame detector 32 to remove dust or impurities that may affect the detection effect, and maintain the high sensitivity and accuracy of the detector. Among them, through the cooperation of the scraping component 411, the self-locking drive component 412, the wiping component 413, and the timing controller, the dust and impurities on the detection windows 321 of the smoke detector 31 and the flame detector 32 can be removed synchronously, the high sensitivity and accuracy of the detector integrated module 3 can be maintained, the performance of the early warning device can be improved, and false alarms and missed alarms can be reduced. At the same time, the self-locking drive component 412 also has a locking function to ensure that the dustproof net 422 can be stably locked to a state of protecting the sensing channel 2 for a long time without power input after cleaning is completed, to prevent malfunction due to external vibration or airflow.

[0038] When the self-cleaning dustproof mechanism 4 is switched to the automatic cleaning mode, the timing controller will start the fan 414. On the one hand, the fan 414 can blow the impurities scraped off the dustproof net 422 by the scraping component from the sensing channel 2 to the outside of the housing 1. On the other hand, a plurality of air ducts 415 are arranged on one side of the housing 1 close to the thermistor 331 of the temperature detector 33. The air outlet of the air duct 415 faces the thermistor 331 of the temperature detector 33. When the fan 414 is started, the air duct 415 guides the air flow, and the air flow is guided to the vicinity of the thermistor 331 of the temperature detector 33 through the air duct 415. Thus, under the synergistic effect of the fan 414 and the air duct 415, the impurities adhering to the thermistor 331 of the temperature detector 33 are blown away, so that the thermistor 331 can sense the change of the ambient temperature more quickly later, thereby improving the response speed of the thermistor 331 of the temperature detector 33.

[0039] Reference Figure 2 and Figure 3 The scraping component 411 includes a plurality of outer scrapers 4111 fixedly mounted on the housing 1, and the plurality of outer scrapers 4111 correspond one-to-one to the plurality of dust-proof nets 422. The housing 1 is also provided with a plurality of inner scrapers 4112 fixedly mounted on the housing 1, and the plurality of inner scrapers 4112 correspond one-to-one to the plurality of dust-proof nets 422, and the inner and outer sides of the dust-proof nets 422 abut against the inner scrapers 4112 and the outer scrapers 4111, respectively.

[0040] The inner and outer sides of each dustproof net 422 are respectively in contact with the inner scraper 4112 and the outer scraper 4111 to form a closed cleaning path. When the self-locking drive component 412 drives the synchronous ring gear 421 to rotate, multiple dustproof nets 422 move synchronously with the synchronous ring gear 421. The movement of the dustproof net 422 drives the inner scraper 4112 and the outer scraper 4111 in contact with it to perform cleaning and scraping work, thereby scraping off dust, small insects and other impurities adhering to the dustproof net 422, ensuring the permeability of the dustproof net 422 and improving the response speed and accuracy of the detector integrated module 3.

[0041] Reference Figure 2 and Figure 3 The self-locking driving component 412 includes a driving shaft 4121 rotatably connected to the housing 1, a driving gear 4122 is fixedly sleeved on the driving shaft 4121, and the driving gear 4122 is meshed with the synchronous ring gear 421. A worm gear 4123 is also fixedly sleeved on the driving shaft 4121, and a worm 4124 is rotatably connected to the housing 1, and the worm 4124 is meshed with the worm gear 4123. A driving motor 4125 is provided at one end of the worm 4124, and the driving motor 4125 is connected to the timing controller.

[0042] When the self-cleaning dustproof mechanism 4 enters the automatic cleaning mode, the timing controller sends a start signal to the drive motor 4125, and the drive motor 4125 starts to run and drives the worm 4124 to rotate. Then the worm 4124 drives the worm wheel 4123 to rotate, and the rotation of the worm wheel 4123 drives the drive shaft 4121 to rotate, and the drive shaft 4121 drives the drive gear 4122 to rotate, so that the drive ring gear rotates accordingly. When the drive motor 4125 stops running, the self-locking characteristics of the worm 4124 and the worm wheel 4123 allow the drive shaft 4121 and the synchronous ring gear 421 to remain in the current position without power input, reducing energy consumption, and ensuring that the dustproof net 422 can be stably locked after cleaning is completed, preventing the dustproof net 422 from malfunctioning due to external vibration or airflow, and improving the stability of the dustproof net 422 in blocking dust from the sensing channel 2.

[0043] Reference Figure 4 and Figure 5 The wiping component 413 includes two parallel guide rails 4131 fixedly arranged on the outer side of the housing 1, a traveling frame 4132 is arranged between the two guiding rails 4131, and the traveling frame 4132 is slidably connected to the two guiding rails 4131. A plurality of traveling wheels 4133 are rotatably connected to the traveling frame 4132, a self-locking hub motor is arranged between the traveling wheels 4133 and the traveling frame 4132, and the self-locking hub motor is connected to the timing controller. A rotating shaft 4134 is rotatably connected to the traveling frame 4132, and a plurality of rotating shafts 4134 are evenly spaced along the length direction of the traveling frame 4132. A flexible wiping member 4135 is fixedly arranged at one end of the rotating shaft 4134 close to the detection window 321 of the flame detector 32, and the flexible wiping member 4135 can be made of high-density fiber fabric, high-density sponge or soft rubber / silicone material.

[0044] Reference Figure 5 and Figure 6, a driven gear 4136 is fixedly sleeved outside the rotating shaft 4134, and a plurality of driven gears 4136 are meshed with each other. A driving gear 4137 is rotatably connected to the traveling frame 4132, and the driving gear 4137 is meshed with one of the driven gears 4136, and a power motor 4138 is provided at one end of the rotating shaft of the driving gear 4137, and the power motor 4138 is connected to the timing controller. A storage box 4139 is fixedly provided on the housing 1, and the storage box 4139 is located at one end of the guide track 4131.

[0045] When the self-cleaning dustproof mechanism 4 enters the automatic cleaning mode, the timing controller sends a start signal to the self-locking hub motor, and the self-locking hub motor starts to run, generating walking power, and driving the walking wheel 4133 to rotate. Then the walking wheel 4133 drives the walking frame 4132 to move along the guide track 4131, and the movement of the walking frame 4132 drives the movement of the entire wiping component 413, and at the same time, the power motor 4138 drives the driving gear 4137 to rotate, and the driving gear 4137 synchronously drives the plurality of driven gears 4136 and the rotating shaft 4134 to rotate, and the rotation of the rotating shaft 4134 drives the flexible wiping member 4135 to rotate, and the flexible wiping member 4135 contacts the detection window 321 of the flame detector 32, thereby cleaning the dust and impurities on the surface of the detection window 321 of the flame detector 32.

[0046] The wiping component 413 will enter the storage box 4139 when not in use. The storage box 4139 can prevent the wiping component 413 from being easily exposed to external dust, especially the flexible wiping component 4135 from accumulating too much dust, so as to maintain its cleaning effect and ensure that the best cleaning effect can be provided when needed. The wiping component 413 can cover the entire area of ​​the detection window 321 of the flame detector 32 through the movement of the traveling frame 4132 and the rotation of the flexible wiping component 4135, so as to ensure the comprehensive cleaning of the detection window 321 of the flame detector 32, and improve the sensitivity and accuracy of the flame detector 32. When the detection window 321 of the flame detector 32 is cleaned, the self-locking hub motor stops running. The self-locking characteristics of the self-locking hub motor keep the traveling frame 4132 in the current position, so as to ensure that the wiping component 413 can be stably locked after cleaning, and at the same time avoid the situation that the detection window 321 is blocked due to the influence of wind force or vibration, etc.

[0047] Reference Figure 4 and Figure 5The wiping component 413 also includes an air collecting bin 4140 fixedly mounted on the walking frame 4132, and a fan 4141 is arranged in the air collecting bin 4140, and the fan 4141 is connected to the timing controller. A plurality of air collecting channels 4142 are fixedly mounted on the air collecting bin 4140, and the plurality of air collecting channels 4142 correspond one-to-one to the plurality of rotating shafts 4134, and the air collecting channels 4142 are sleeved on the outer sides of the corresponding rotating shafts 4134. The rotating shaft 4134 is hollow inside and has openings at both ends. A plurality of pressing plates 4143 are arranged between the air collecting channels 4142 and the flexible wiping member 4135, and the plurality of pressing plates 4143 correspond one-to-one to the plurality of rotating shafts 4134, and the rotating shafts 4134 are rotatably connected to the corresponding pressing plates 4143. A plurality of damping telescopic rods 4144 are arranged between the air collecting channel 4142 and the pressure plate 4143 . A damping spring 4145 is sleeved on the outer side of the damping telescopic rod 4144 . The damping spring 4145 is in a compressed state and gives a force to the pressure plate 4143 to move closer to the detection window 321 of the flame detector 32 .

[0048] When the self-cleaning and dust-proof mechanism 4 enters the automatic cleaning mode, the timing controller sends a start signal to the fan 4141, and the fan 4141 starts to operate to generate suction. The operation of the fan 4141 forms a negative pressure in the air collecting bin 4140 and the air collecting channel 4142. Since the air collecting channel 4142 is sleeved on the outside of the rotating shaft 4134, the rotating shaft 4134 is hollow inside and has openings at both ends, the dust scraped off by the flexible wiper 4135 will be absorbed by the negative pressure generated by the fan 4141 into the hollow part of the rotating shaft 4134, and then enter the air collecting bin 4140 through the air collecting channel 4142, and finally be sucked in by the fan 4141 and discharged to the outside. The double cleaning action of the fan 4141 and the flexible wiper 4135 can, on the one hand, fully clean the detection window 321 of the flame detector 32, thereby improving the sensitivity and accuracy of the flame detector 32, and on the other hand, the negative pressure generated by the fan 4141 can absorb the dust adhering to the flexible wiper 4135 and the dust scraped off, thereby keeping the flexible wiper 4135 clean. At the same time, under the action of the damping telescopic rod 4144 and the damping spring 4145, the pressing plate 4143 can drive the flexible wiper 4135 to be close to the detection window 321 of the flame detector 32, thereby improving the wiping effect of the flexible wiper 4135.

[0049] The implementation principle of a multifunctional integrated composite fire warning device in the embodiment of the present application is as follows: the smoke detector 31, the flame detector 32 and the temperature detector 33 respectively monitor the concentration of smoke particles in the air, the flame radiation intensity and the changes in the ambient temperature, and ensure all-round environmental monitoring by collecting data. The main control unit is responsible for collecting data from the detector integrated module 3, analyzing and processing the data through the built-in algorithm, and judging whether the warning threshold is reached according to the analysis results. Once the fire signal is confirmed, the main control unit will send a control instruction to trigger the warning mechanism, including starting the alarm, transmitting the warning information to the cloud server or other terminal equipment in real time through the communication interface, realizing remote monitoring and management, so as to quickly respond to the fire. When the self-cleaning dustproof mechanism 4 is in the anti-false alarm mode, the dustproof component 42 is started to prevent non-fire factors such as dust and small insects from entering the detector integrated module 3, and reduce false alarms caused by external interference. When the self-cleaning dustproof mechanism 4 is in the automatic cleaning mode, the self-cleaning component 41 and the dustproof component 42 are both started, and the dustproof component 42 cooperates with the self-cleaning component 41 to remove dust and impurities on the detector integrated module 3, keep the detector integrated module 3 clean, and improve the accuracy of data collection. Among them, through the cooperation of the detector integrated module 3, the main control unit, the communication interface, the self-cleaning and dust-proof mechanism 4, etc., it can quickly respond to fire signals in the early stage of fire, improve the comprehensive judgment ability of the fire warning device, adapt to the complex and changeable actual environmental needs, and at the same time improve the accuracy and reliability of the warning, so as to gain precious time for the evacuation of personnel and fire extinguishing; and the self-cleaning and dust-proof mechanism 4 reduces the maintenance workload of the fire warning device, cleans the fire warning device regularly and in time, reduces unnecessary interference, reduces the false alarm rate, enables the fire warning device to provide more accurate and timely fire warnings, and improves the overall performance of the warning system.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
