Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automatic fire alarm equipment and systems, and particularly relates to an automatic fire alarm equipment and system. Background Art
[0002] Automatic fire alarm equipment, also known as intelligent fire alarm equipment, is a device with the function of automatically alarming in the initial stage of a fire. Once a fire occurs, it can send an alarm signal on the alarm in the fire control center, display the location or area code where the fire occurs. After receiving the alarm, the management personnel immediately start the fire alarm broadcast, organize the personnel to evacuate safely, start the fire elevator, the alarm linkage signal drives the automatic fire extinguishing control cabinet to work, close the fire doors to seal the fire area, and automatically spray water or fire extinguishing agent to extinguish the fire in the fire area. At the same time, start the fire pump and the automatic smoke exhaust device to minimize the life and property losses caused by the fire. The role of the high-rise building fire automatic alarm system is not only to detect and alarm the occurrence of a fire and remind the personnel to evacuate in time, but also to notify the relevant fire departments for fire fighting and rescue.
[0003] In the existing intelligent fire alarm system, through the cooperation of a smoke sensor and a temperature sensor, alarm information is sent, and at the same time, an automatic sprinkler system equipped with a temperature sensing element intervenes in the fire source when the temperature in the room rises to a certain degree, winning time for escape and other fire fighting measures. However, it can be found in actual use that when the fire source starts to burn, the temperature in the room does not rise rapidly, and at the same time, there is not enough smoke generated to trigger the smoke sensor. This is the lag of the fire alarm equipment, which cannot make a judgment in the first time of the fire source. Secondly, at the fire scene, the main harm to the human body is the toxic gas generated by the fire. When the fire is triggered, only the fire source is intervened, and the smoke is not intervened, resulting in the imperfection of the fire alarm equipment, and further causing losses to the property and health of citizens. Summary of the Invention
[0004] The main purpose of the present invention is to provide an automatic fire alarm equipment, aiming to timely judge the fire situation, effectively inhibit the spread of the fire, and reduce the affected area of the fire.

[0006] In a possible implementation manner, the clamping component includes: A clamping chassis, which is fixedly connected to the first partition board, and the clamping sleeve is mutually clamped with the clamping chassis; A transmission sleeve, which is rotatably connected to the water supply pipe and is fixedly connected to the flipping table; A linkage plate, which is fixedly connected to the transmission sleeve. A clamping block is hinged on the linkage plate.

[0007] In a possible implementation manner, a first positioning groove and a second positioning groove are respectively formed on the clamping sleeve and the clamping chassis for the mutual clamping of the clamping sleeve and the clamping chassis.
[0008] In a possible implementation manner, the reset component includes a plurality of reset columns. Each reset column is slidably connected to the flipping table. One end of each reset column facing the clamping sleeve is slidably abutted against the clamping sleeve. A reset spring is sleeved on each reset column, and the two ends of the reset spring are respectively abutted against the inner wall of the flipping table and the reset column.
[0009] In a possible implementation manner, a clamping groove is annularly formed on the upper side of the clamping sleeve. One end of the reset column facing the clamping sleeve is formed into a spherical structure, and each reset column is abutted against the inner wall of the clamping groove.
[0010] In a possible implementation manner, the defogging component includes: A defogging fan, which is fixedly connected to the water supply pipe; A defogging cover, which is fixedly connected between the first partition board and the second partition board; The first gear, which is fixedly connected to the water supply pipe, and a second gear meshes with one side of the first gear; The second motor, which is fixedly connected to the side of the demisting cover facing the demisting fan, and the drive shaft of the second motor is fixedly connected to the second gear; The differential mechanism, which ensures that the demisting fan rotates continuously without affecting the water outlet direction of the water spraying joint.
[0011] In a possible implementation manner, the differential mechanism includes: The third gear, which is fixedly connected to the transmission sleeve; The fourth gear, which is fixedly connected to the water supply pipe; The drive seat, which is fixedly connected to the outer wall of the water supply pipe. A fifth gear is rotatably connected to the drive seat. The fifth gear is arranged between the third gear and the fourth gear and meshes with the third gear and the fourth gear respectively.
[0012] In a possible implementation manner, a protective cover is fixedly connected to the lower side of the first partition board. The differential mechanism is arranged in the protective cover to isolate the demisting fan from the differential mechanism.
[0013] In a possible implementation manner, the drive assembly includes: The third motor, which is fixedly connected to the first partition board. A sixth gear is fixedly connected to the drive shaft of the third motor. A transmission tooth ring meshes with the sixth gear, and the transmission tooth ring is fixedly connected to the outer side surface of the clamping sleeve.
[0014] Through the action of the infrared sensor installed on the clamping sleeve, the infrared sensor can freely rotate and adjust by sensing the relative temperature difference in the room. The infrared sensor judges whether there is a fire by sensing the relative temperature difference data in the room. When the temperature difference in a local area exceeds the set threshold, the defogging component drives the clamping component to perform synchronous operations, and the position of the infrared sensor is accurately limited, so as to ensure that the heat source detected by it can correctly point to the fire source position, facilitating firefighters to judge the specific location of the fire through the orientation of the infrared sensor. Firefighters can quickly determine the fire source and the trend of fire spread, and then analyze the cause of the fire. And through an external water pump, the water spray joint can quickly and timely aim at the fire point and spray water to extinguish the fire source, which can not only effectively inhibit the spread of the fire, but also reduce the affected area of the fire, thus providing more escape time for the residents and reducing the losses caused by the fire. In addition, the defogging component can effectively remove the smoke and dust in the fire scene after the fire occurs, reduce the impact of smoke, poisonous gas and dust on the residents, make the clarity in the room higher, enable the residents to process the fire or escape more quickly, and through the differential mechanism, the independent operation of the defogging function and the fire extinguishing function is guaranteed, so that the fire extinguishing function can be timely put into the fire extinguishing operation, further improving the overall fire extinguishing ability and use safety of the equipment, and ensuring the life and property safety of the residents.
[0015] Another object of the present invention is to provide an automatic fire alarm system, aiming to quickly obtain the fire situation and give a quick alarm to ensure the life and property safety of residents.
[0016] To achieve the above object, an automatic fire alarm system proposed by the present invention includes: An infrared thermal module for transmitting the data detected by the infrared sensor to the driving component, so that the driving component drives the infrared sensor towards the thermal source; A heat removal module for transmitting the data detected by the infrared thermal module to the water pump connected to the water supply pipe, pumping water to the water spray joint through the water pump, and driving the first motor to work according to the cooling effect at the same time; A smoke warning module, which is provided with a smoke sensor, a buzzer and an alarm lamp, for detecting the smoke concentration in the room and providing different frequency buzzer bands and alarm lamp flashing frequencies according to the smoke concentration; A defogging module for transmitting the data received by the smoke warning module to the defogging component, so that the defogging component extracts the flue gas and poisonous gas from the room and reduces the impact of the poisonous gas on the residents; An alarm module, which is provided with a remote alarm module and a broadcast module, remotely alarms through the data transmitted by the smoke warning module, and notifies the surrounding residents through the broadcast function; The main control module is arranged outside the house and is used for overall control of the working states of the infrared thermal module, the fire extinguishing module, the smoke warning module, the defogging module and the alarm module.
[0017] The technical solution of the present invention determines whether there is a fire in the house by obtaining the relative temperature difference data inside the house. Since the spread speed of the fire is slow in the initial stage and the smoke aggregation efficiency is slow, when detecting the fire only from the smoke alarm, the fire is already relatively large and it is easy to have a lag. However, by obtaining the relative temperature difference data inside the house, when the fire burns in the initial stage, it will quickly heat the air in a certain area inside the house, thereby generating a large temperature difference inside the house. This temperature difference data can be quickly obtained when the fire just appears. Then, by setting a threshold value, when the obtained temperature difference data exceeds the threshold value, the fire extinguishing module will perform a fire extinguishing operation on the ignition point. This fire extinguishing operation only plays the role of suppressing the spread speed of the fire. And the infrared thermal module transmits information through the main control module, and then synchronously triggers the smoke warning module and the alarm module to quickly inform the household and the relevant fire departments, ensuring the property and life safety of the user. At the same time, the defogging module is also turned on synchronously to guide the unburned toxic gases and soot in the indoor air upward and extract them, reducing the influence of toxic gases on the household, and at the same time improving the indoor vision situation, enabling the household to more easily control or escape from the ignition point.

[0022] In order to make the object, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Embodiment 1
[0023] The present invention provides an automatic fire alarm device; Referring to Figures 1 to 8 , in the embodiment of the present invention, the automatic fire alarm device includes: A first partition 11 and a second partition 12, both the first partition 11 and the second partition 12 are detachably and fixedly connected to the ceiling of the room; A water supply pipe 13, the water supply pipe 13 is connected between the first partition 11 and the second partition 12, the upper end of the water supply pipe 13 is fixedly connected with a turning table 14, a spraying joint 15 is rotatably connected to the turning table 14, and a plastic hose 16 is connected between the water supply pipe 13 and the spraying joint 15; A first motor 17 for adjusting the relative angle between the spraying joint 15 and the turning table 14; The clamping sleeve 18 is rotatably arranged between the first partition plate 11 and the flipping table 14. An infrared sensor 19 is detachably and fixedly connected to the clamping sleeve 18 for sensing the relative temperature inside the house. A driving component for driving the rotation of the clamping sleeve 18 is connected to one side of the clamping sleeve 18; The clamping component is arranged between the first partition plate 11 and the flipping table 14, and is used to ensure that the water outlet direction of the water spraying joint 15 is the same as the orientation of the infrared sensor 19; The defogging component is arranged on the side of the first partition plate 11 facing the second partition plate 12 and is used to discharge the toxic gases inside the house; The infrared sensor 19 installed on the clamping sleeve 18 can freely rotate and adjust by sensing the relative temperature difference inside the house. The infrared sensor 19 judges whether there is a fire by sensing the relative temperature difference data inside the house. When the temperature difference in a local area exceeds the set threshold, the defogging component drives the clamping component to perform synchronous operations, and the position of the infrared sensor 19 is accurately limited, so as to ensure that the heat source detected by it can correctly point to the fire source position, facilitating firefighters to judge the specific location of the fire according to the orientation of the infrared sensor 19. Firefighters can quickly determine the fire source and the trend of the fire spread, and then analyze the cause of the fire. And through an external water pump, the water spraying joint 15 can quickly and timely aim at the fire point and spray water to extinguish the fire source, which can not only effectively inhibit the spread of the fire, but also reduce the affected area of the fire, thus providing more escape time for the residents and reducing the losses caused by the fire. In addition, the defogging component can effectively remove the smoke and dust in the fire scene after the fire occurs, reduce the impact of the smoke, poisonous gas and dust on the residents, make the clarity inside the house higher, enable the residents to process the fire or escape more quickly, and through the differential mechanism, the independent operation of the defogging function and the fire extinguishing function is guaranteed, so that the fire extinguishing function can be timely put into the fire extinguishing operation, further improving the overall fire extinguishing ability and the use safety of the equipment, and protecting the lives and property safety of the residents.
[0024] Reference Figures 2 to 8 , the clamping component includes: The clamping chassis 21 is fixedly connected to the first partition plate 11, and the clamping sleeve 18 is mutually clamped with the clamping chassis 21; The transmission sleeve 22 is rotatably connected to the water supply pipe 13, and the transmission sleeve 22 is fixedly connected to the flipping table 14; The linkage plate 23 is fixedly connected to the transmission sleeve 22. A clamping block 24 is hinged on the linkage plate 23. The clamping block 24 is slidably abutted against the clamping chassis 21, and the clamping block 24 is abutted against one side of the clamping sleeve 18 facing the clamping chassis 21; The articulated relationship between the linkage plate 23 and the clamping block 24 enables the linkage plate 23 to drag the clamping block 24 towards the linkage plate 23 in either rotational direction through the articulated relationship, causing the clamping sleeve 18 abutted against the upper side of the linkage plate 23 to drop. A first clamping block 181 is fixedly connected to the inner side surface of the clamping sleeve 18, and a second clamping block 141 is fixedly connected to the turntable 14. A reset assembly is arranged between the turntable 14 and the clamping sleeve 18 and is used to drive the clamping sleeve 18 to be clamped with the clamping chassis 21. The clamping assembly enables the infrared sensor 19 installed on the clamping sleeve 18 to freely rotate and adjust by sensing the relative temperature difference inside the room when there is no fire. The infrared sensor 19 judges whether there is a fire by sensing the relative temperature difference data inside the room. When the temperature difference in a local area exceeds the set threshold, the clamping assembly is linked with the defogging assembly, and the clamping assembly works under the linkage action of the defogging assembly to separate the clamping sleeve 18 from the clamping block 24. Thus, under the action of the reset assembly, the clamping sleeve 18 moves towards the clamping chassis 21, and then the clamping sleeve 18 is quickly clamped with the clamping chassis 21. With the quick clamping of the clamping sleeve 18 and the clamping chassis 21, the position of the infrared sensor 19 is accurately limited, ensuring that the heat source detected by it can correctly point to the fire source position, facilitating the fire-fighting personnel to judge the specific location of the fire according to the orientation of the infrared sensor 19. In this way, the fire-fighting personnel can quickly determine the fire source and the trend of the fire spread, and then analyze the cause of the fire. In addition, the quick clamping action of the clamping sleeve 18 also accurately limits the orientation of the water spraying joint 15. Through an external water pump, the water spraying joint 15 can quickly and timely aim at the fire point and spray water to extinguish the fire source, which can not only effectively inhibit the spread of the fire, but also reduce the affected area of the fire, thus providing more escape time for the residents, reducing the losses caused by the fire, and ensuring the life and property safety of the residents.
[0025] Reference Figures 6 to 8 , a first positioning groove 182 and a second positioning groove 211 are respectively formed on the clamping sleeve 18 and the clamping chassis 21 for the mutual clamping of the clamping sleeve 18 and the clamping chassis 21. When the clamping sleeve 18 moves towards the clamping chassis 21 under the action of the reset component, the clamping between the clamping sleeve 18 and the clamping chassis 21 becomes more stable through the mutual clamping action of the first positioning groove 182 and the second positioning groove 211. Since the stability of the clamping sleeve 18 is ensured, the orientation angle of the infrared sensor 19 can also be more accurately aligned with the target. This is crucial for the fire extinguishing operation because an accurate angle can ensure that the infrared sensor 19 can accurately detect the position and temperature change of the fire source, thereby providing effective alarm information in a timely manner. In addition, the precise positioning of the infrared sensor 19 helps the subsequent firefighters to judge the cause of the accident. Through the stable and accurate data of the infrared sensor 19, the firefighters can identify the fire source and the specific situation of the fire spread faster and more accurately, so as to formulate more effective extinguishing strategies and treatment plans.
[0026] Reference Figures 6 to 8 , the reset component includes a number of reset posts 31. Each reset post 31 is slidably connected to the turntable 14. One end of each reset post 31 facing the clamping sleeve 18 is slidably abutted against the clamping sleeve 18. A reset spring 32 is sleeved on each reset post 31. The two ends of the reset spring 32 are respectively abutted against the inner wall of the turntable 14 and the reset post 31; The reset post 31 is slidably connected to the turntable 14 and slidably abuts against one end of the clamping sleeve 18, ensuring the limit of the clamping sleeve 18 during rotation or movement. When the clamping block 24 is separated from the lower side of the clamping sleeve 18, the reset component starts to act, enabling the clamping sleeve 18 to be continuously squeezed during the reset process, and finally pushing the clamping sleeve 18 towards the direction of the clamping chassis 21, ensuring that the clamping sleeve 18 can be accurately and stably clamped with the clamping chassis 21, thereby fixing its position and limiting the angle of the clamping sleeve 18 to ensure the stable position of the infrared sensor 19 facing the ignition point, facilitating the subsequent firefighters to confirm the ignition point. At the same time, the angle limit after the clamping of the clamping sleeve 18 also limits the rotation angle of the turntable 14, enabling the water spraying joint 15 installed on the turntable 14 to face the ignition position in the first time. Through the external water pump, water is quickly sprayed to the ignition point through the water spraying joint 15, ensuring that the fire can be detected and eliminated in the shortest time, improving the response speed and accuracy of the fire extinguishing system, and providing more intuitive and reliable fire extinguishing guidance for the firefighters, ensuring the efficient and stable operation of the fire prevention and control system.
[0027] Reference Figure 3 and Figures 6 to 8 , a clamping groove 183 is annularly formed on the upper side of the clamping sleeve 18. One end of the reset post 31 facing the clamping sleeve 18 is formed into a spherical structure, and each reset post 31 abuts against the inner wall of the clamping groove 183; The rotational movement of the clamping sleeve 18 is limited by the reset post 31, effectively preventing the clamping sleeve 18 from over-rotating or moving irregularly during rotation, thereby improving the stability and precision of rotation. In addition, the infrared sensor 19 provides real-time feedback information to the drive assembly by obtaining the relative temperature difference data inside the house. When the infrared sensor 19 detects a temperature change and analyzes the specific location of the fire source, the drive assembly will drive the clamping sleeve 18 to rotate according to this data. Due to the limiting effect of the reset post 31, the rotation process of the clamping sleeve 18 becomes more controllable, avoiding excessive deviation of the rotation angle and ensuring that the clamping sleeve 18 can be accurately adjusted to the correct position.
[0028] Reference Figures 2 to 7 , the defogging assembly includes: A defogging fan 41, which is fixedly connected to the water supply pipe 13; A defogging cover 42, which is fixedly connected between the first partition 11 and the second partition 12; A first gear 43, which is fixedly connected to the water supply pipe 13, and a second gear 44 meshes with one side of the first gear 43; A second motor 45, which is fixedly connected to the side of the defogging cover 42 facing the defogging fan 41, and the drive shaft of the second motor 45 is fixedly connected to the second gear 44; A differential mechanism, which ensures that the defogging fan 41 rotates continuously without affecting the water outlet direction of the water spraying joint 15; After a fire breaks out, the defogging assembly can effectively remove the smoke and dust in the fire scene, reduce the impact of smoke, poisonous gas and dust on the residents, make the clarity inside the house higher, enable the residents to handle the fire or escape more quickly, and through the differential mechanism, ensure the independent operation of the defogging function and the fire extinguishing function, enable the fire extinguishing function to be promptly put into fire extinguishing operations, improve the overall fire extinguishing ability and use safety of the equipment, and protect the lives and property safety of the residents.
[0029] Reference Figures 2 to 8 , the differential mechanism includes: A third gear 51, which is fixedly connected to the transmission sleeve 22; A fourth gear 52, which is fixedly connected to the water supply pipe 13; A drive seat 53, which is fixedly connected to the outer wall of the water supply pipe 13. A fifth gear 54 is rotatably connected to the drive seat 53. The fifth gear 54 is arranged between the third gear 51 and the fourth gear 52 and meshes with the third gear 51 and the fourth gear 52 respectively; The differential mechanism enables the demisting fan 41 to have sufficient rotational force and sufficient suction force. After the clamping sleeve 18 and the clamping chassis 21 are clamped with each other, the water spraying joint 15 can rotate along with the differential mechanism, so that the orientation of the water spraying joint 15 is consistent with the orientation of the infrared sensor 19. Then, by adjusting the water outlet angle of the water spraying joint 15, the fire extinguishing effect of the water spraying joint 15 on the fire can be better adjusted. At the same time, the water spraying joint 15 can be set to the existing fire-fighting interface model, so that the water outlet effect of the water spraying joint 15 can be more adapted to the fire. Since this kind of fire-fighting interface is well-known technology to those skilled in the art, it will not be elaborated here.
[0030] Reference Figures 6 to 7 , a protective cover 55 is fixedly connected to the lower side of the first partition 11, and the differential mechanism is arranged in the protective cover 55 for isolating the demisting fan 41 from the differential mechanism; The differential mechanism is arranged in the protective cover 55, mainly for isolating the demisting fan 41 from the differential mechanism to prevent smoke and dust from directly entering the differential mechanism and protecting its normal operation. When the demisting component works, the suction force generated by the demisting component will cause a large amount of smoke and dust generated by the fire to move towards the demisting cover 42. In order to prevent these smoke and dust from affecting the various components of the differential mechanism, the setting of the protective cover 55 effectively isolates the differential mechanism and reduces its pollution risk. There are holes on the first partition 11. Due to the suction force, the smoke and dust will enter the demisting cover 42 through these holes and be discharged through the holes in the demisting cover 42, and finally the smoke and dust will be quickly discharged through the fan pipeline installed on the outside, so that the smoke and dust will not contact the components in the differential mechanism. That is, it can not only effectively reduce the impact of smoke, dust and toxic gases on the residents, but also guide these harmful substances upward to improve the visual clarity of the residents, thereby improving safety. In case of a fire, a clear field of vision can increase the chance of residents' escape. Especially during the process of escaping while bending down, this design provides more survival opportunities for the residents.
[0031] Reference Figures 2 to 3 and Figures 6 to 8 , the driving component includes: a third motor 61, the third motor 61 is fixedly connected to the first partition 11, a sixth gear 62 is fixedly connected to the driving shaft of the third motor 61, and a transmission gear ring 63 is engaged with the sixth gear 62, and the transmission gear ring 63 is fixedly connected to the outer side surface of the clamping sleeve 18; Through the interaction of the driving component through the third motor 61, the transmission gear ring 63 and the clamping sleeve 18, the elimination efficiency of the water spraying joint 15 for the ignition point is optimized. The relative temperature difference data in the house is obtained by the infrared sensor 19, and the third motor 61 automatically adjusts the rotation angle of the clamping sleeve 18 according to this feedback information to achieve accurate fire source positioning and fire extinguishing. Compared with the traditional single smoke sensor, after a fire breaks out, the relative temperature in the house will change, that is, the temperature in a certain area of the house will rise rapidly, and then it is obtained by the infrared sensor 19, and it can be triggered in time due to the fire situation. This not only greatly shortens the response time in the initial stage of the fire, improves the fire extinguishing efficiency, but also can make real-time adjustments according to the fire source position to ensure that the fire extinguishing water flow is accurately sprayed on the fire point, reducing water resource waste. Embodiment 2
[0032] The present invention also proposes an automatic fire alarm system, referring to Figures 1 to 8 including: An infrared thermal module for transmitting the data detected by the infrared sensor 19 to the driving component to make the driving component drive the infrared sensor 19 towards the thermal source; A fire extinguishing module for transmitting the data detected by the infrared thermal module to the water pump connected to the water supply pipe 13, pumping water to the water spraying joint 15 through the water pump, and simultaneously driving the first motor 17 to work according to the cooling effect; A smoke warning module, which is provided with a smoke sensor, a buzzer and an alarm lamp, for detecting the smoke concentration in the house and providing different frequency buzzer wave bands and alarm lamp flashing frequencies according to the smoke concentration; A defogging module for transmitting the data received by the smoke warning module to the defogging component to make the defogging component extract the flue gas and poisonous gas from the house and reduce the impact of the poisonous gas on the residents; An alarm module, which is provided with a remote alarm module and a broadcast module, for remotely alarming through the data transmitted by the smoke warning module and informing the surrounding residents through the broadcast function; A main control module, which is arranged outside the house, for overall controlling the working states of the infrared thermal module, the fire extinguishing module, the smoke warning module, the defogging module and the alarm module; By obtaining the relative temperature difference data inside the house to determine whether there is a fire inside. Since the spread speed of the fire is slow in the initial stage and the smoke accumulation efficiency is also slow, when detecting the fire only from the smoke alarm, the fire is already relatively large, and there is an easy lag. However, by obtaining the relative temperature difference data inside the house, when the fire burns in the initial stage, it will quickly heat the air in a certain area inside the house, thereby generating a large temperature difference inside the house. This temperature difference data can be quickly obtained when the fire just appears. Then, by setting a threshold, when the obtained temperature difference data exceeds the threshold, the fire extinguishing module will perform fire extinguishing operations on the fire starting point. This fire extinguishing operation only serves to inhibit the spread speed of the fire. And the infrared thermal sensor module transmits information through the main control module, thereby synchronously triggering the smoke warning module and the alarm module to quickly inform the residents and relevant fire departments to ensure the property and life safety of users. At the same time, the defogging module is also turned on synchronously to guide the unburned toxic gases and soot in the indoor air upward and extract them, reducing the impact on residents caused by the toxic gases, and at the same time improving the indoor vision situation, enabling residents to more easily control the fire starting point or escape.
