Description

Technical Field

[0001] The present invention relates to the technical field of indoor fire protection, and in particular to a distributed fire prevention and control device and a control method based on the Internet of Things. Background Art

[0002] Indoor fire protection refers to facilities installed indoors to extinguish initial fires occurring in buildings. It mainly includes indoor fire hydrants, automatic sprinkler fire protection, water mist fire extinguishing, foam fire extinguishing, carbon dioxide fire extinguishing, halogenated hydrocarbon fire extinguishing, dry powder fire extinguishing and fire monitoring. Installing indoor fire protection is an effective and necessary safety measure.

[0003] A fire monitoring device for indoor fire fighting with Chinese patent application number 202320772215.X includes a load-bearing plate and a shell, a cross-shaped fixing plate is provided at the upper end of the load-bearing plate, a blower mechanism is provided at the upper end of the load-bearing plate and at the corners, a rotating mechanism is provided between the load-bearing plate and the shell, two groups of lenses are symmetrically provided on the outer side wall of the shell, and the rotating mechanism includes a support plate. However, the device only plays a monitoring role, but cannot autonomously extinguish fire and exhaust smoke, which can easily cause the fire to spread further.

[0004] An automatic fire alarm device based on fire monitoring with Chinese patent application number 202311464446.5 includes a smoke alarm housing, an inner diversion tube is fixedly installed inside the smoke alarm housing, an inner partition plate is fixedly installed inside the inner diversion tube, the inner diversion tube is closed, an exhaust chamber and a smoke sensing chamber are formed on both sides of the inner partition plate inside the inner diversion tube, a smoke sensor is installed inside the smoke sensing chamber, but when a fire occurs, the dust cover of the device is easily blocked, thereby affecting the detection accuracy of the smoke sensor.

[0005] When the equipment is used for a long time, the dust cover is often easily clogged with dust, which in turn affects the ventilation efficiency of the equipment. When a fire occurs, impurities in the thick smoke are more likely to clog the dust cover, reducing the ventilation efficiency of the equipment. At the same time, when a water pipe is added to the equipment to spray water to extinguish the fire, the water flow size sprayed from the water pipe is constant, so that the coverage area of ​​the water spray is constant, which makes the auxiliary fire extinguishing effect of the equipment poor. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a distributed fire prevention and control device and control method based on the Internet of Things.

[0007] The present invention comprises a connecting assembly, a directional fire extinguishing assembly is arranged at the lower end of the connecting assembly, a ventilation assembly is arranged at the lower end of the directional fire extinguishing assembly, and an adjusting assembly is also arranged on the directional fire extinguishing assembly;

[0008] The directional fire extinguishing assembly comprises a rotating disk, a water spray pipe is arranged on the rotating disk, a fire extinguishing ball is arranged at the end of the water spray pipe, a groove is arranged at the side end of the fire extinguishing ball, a plug rod is arranged at the side of the water spray pipe close to the ventilation assembly, a spring is arranged between the plug rod and the water spray pipe, and the plug rod has magnetism;

[0010] The regulating assembly comprises a first annular hose, a second annular hose is arranged on the water spray pipe, and a connecting pipe communicating with the second annular hose is arranged on the first annular hose.

[0011] By arranging components such as smoke sensors, magnet blocks, electromagnets, scrapers, torsion springs and the first annular hose, when the device detects a fire in a room with the assistance of the smoke sensor, the electromagnet is energized to change the inclination angle of the fan blades, thereby causing the device to generate pulse wind force, which is beneficial for clearing the blockage of the filter cover. After the electromagnet is energized, as the fan blades rotate, the magnet block interacts with the electromagnet to move the scraper up and down, thereby clearing the blockage of the filter cover. At the same time, the up and down movement of the scraper will intermittently squeeze the first annular hose, so that the water flow sprayed from the water spray pipe is in a pulse state, the water spraying area of ​​the water spray pipe is increased, and its fire extinguishing effect is enhanced. When the smoke sensor detects that the fire intensity in the room is increasing, the current of the electromagnet is increased, thereby canceling the limit of the fire extinguishing ball. Therefore, the fire extinguishing ball will be sprayed out with the water flow, so that the fire extinguishing ball hits the fire location, and the flame retardant liquid in the fire extinguishing ball is discharged to assist in fire extinguishing, thereby improving the fire extinguishing effect of the equipment.

[0012] Preferably, the connection assembly comprises a connection ring sleeve, mounting plates are arranged on both sides of the connection ring sleeve, mounting holes are arranged on the mounting plates, and a smoke collecting pipe is arranged at the center of the connection ring sleeve.

[0019] The present invention also provides a control method for a distributed fire prevention and control device based on the Internet of Things, comprising the following steps:

[0020] Step 1: Start the second motor to rotate the fan blades, thereby generating upward wind force in the device, so that the device can ventilate and exhaust the room;

[0021] Step 2: When a fire occurs indoors, the detection value of the smoke sensor in the device will increase during the process of ventilating and exhausting the indoor air, thereby causing the device to determine that a fire has occurred indoors;

[0022] Step 3: Based on step 2, the device determines the specific location of the fire according to the cooperation of multiple smoke sensors, controls the water sprinkler to turn to the direction of the fire, and makes the water sprinkler spray water to extinguish the fire;

[0023] Step 4: Based on step 2, when the device is located above the fire, the detection values ​​of multiple smoke sensors in the device are similar, so the device cannot determine the direction of the fire. At this time, the device controls the turntable to continue to rotate and the water pipe to spray water. At this time, the water pipe sprays water around to extinguish the fire;

[0024] Step 5. Based on step 4, even if the detection value of the smoke sensor in other devices near the device does not meet the standard, other devices will control their water pipes to spray water towards the location of the fire to assist in extinguishing the fire.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. By setting up smoke sensors, magnets, electromagnets, scrapers and other components, when the device detects a fire indoors with the assistance of the smoke sensor, the electromagnet is energized to change the inclination angle of the fan blades, thereby causing the device to generate pulse wind force, which is beneficial for clearing the filter cover.

[0027] 2. By setting up components such as smoke sensors, magnet blocks, electromagnets, scrapers, torsion springs and the first annular hose, after the electromagnet is energized, as the fan blades rotate, the magnet block and the electromagnet interact to move the scraper up and down, thereby clearing the filter cover. At the same time, the up and down movement of the scraper will intermittently squeeze the first annular hose, making the water flow sprayed from the sprinkler pipe in a pulsed state, thereby increasing the water spraying area of ​​the sprinkler pipe and enhancing its fire extinguishing effect.

[0028] 3. By setting up components such as smoke sensors, magnet blocks, electromagnets, scrapers and the first annular hose, when the fire in the room increases with the assistance of the smoke sensor, the current of the electromagnet is increased, thereby canceling the limit of the fire extinguishing ball.

[0036] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0037] like Figures 1 to 5 As shown, the distributed fire prevention and control device based on the Internet of Things of the present invention includes a connecting component 1, a directional fire extinguishing component 2 is arranged at the lower end of the connecting component 1, and a ventilation component 3 is arranged at the lower end of the directional fire extinguishing component 2. With the assistance of the connecting component 1, the device can be installed at the top of the interior of the house, and then the air in the house can be replaced with the assistance of the ventilation component 3. In the process of controlling the replacement, the smoke sensor in the ventilation component 3 can detect the smoke concentration in the air. When the smoke concentration is too high, it indicates that a fire has occurred in the house, and then the fire is extinguished with the assistance of the directional fire extinguishing component 2.

[0038] The directional fire extinguishing assembly 2 includes a turntable 201, on which a water spray pipe 202 is arranged. The connecting assembly 1 includes a connecting ring sleeve 101. A water inlet pipe 106 is also arranged at the upper end of the connecting ring sleeve 101. An electric control valve is arranged in the water inlet pipe 106. A ring piece 105 is rotatably arranged at the lower end of the connecting ring sleeve 101. The water spray pipe 202 passes through the ring piece 105 and is communicated with the connecting ring sleeve 101. The water inlet pipe 106 is communicated with the water supply system. After the electric control valve is opened, water in the water supply system enters the connecting ring sleeve 101 through the water inlet pipe 106, and the water in the connecting ring sleeve 101 enters the water spray pipe 202. Then the water spray pipe 202 sprays water at the location where the fire occurs to extinguish the fire. In addition, due to the effect of the ring piece 105, during the process of the turntable 201 driving the water spray pipe 202 to rotate, with the assistance of the ring piece 105, the water spray pipe 202 can be stably connected with the connecting ring sleeve 101, so that the water spraying of the equipment is more stable.

[0039] Mounting plates 102 are provided on both sides of the connecting ring sleeve 101, mounting holes 103 are provided on the mounting plates 102, a smoke collecting pipe 104 is provided in the center of the connecting ring sleeve 101, the turntable 201 is rotatably connected to the smoke collecting pipe 104, and connecting bolts are provided in the mounting holes 103 on the mounting plates 102, so that the equipment can be fixed on the indoor ceiling.

[0040] An annular groove 207 is provided at the lower end of the turntable 201, and a gear ring is provided in the annular groove 207 on a side away from the center of the turntable 201. A first motor 107 is provided on the smoke collecting pipe 104, and a transmission gear 108 is provided at the output end of the first motor 107. The transmission gear 108 is meshed with the gear ring for transmission. After the first motor 107 is started, the output end of the first motor 107 will drive the rotation of the transmission gear 108, and the rotation of the transmission gear 108 drives the rotation of the gear ring through the meshing transmission, so that the turntable 201 rotates. The first motor 107 is assisted to provide power for the rotation of the turntable 201, so that the rotation of the turntable 201 is more stable and controllable.

[0041] The ventilation component 3 includes a filter cover 301, and a plurality of smoke sensors are arranged on the inner wall of the filter cover 301. A fan blade 303 is rotatably arranged inside the filter cover 301. With the assistance of the smoke sensor, smoke in the air can be detected to determine whether a fire occurs indoors. Wind can be generated by the rotation of the fan blade 303, and the air in the room is discharged through the smoke collecting pipe 104 with the assistance of the wind.

[0042] A bottom groove 305 is provided at the lower end of the filter cover 301, a horizontal plate 306 is provided in the bottom groove 305, a second motor 307 is provided at the lower end of the horizontal plate 306 in the bottom groove 305, a mounting plate 308 is provided at the output end of the second motor 307 above the horizontal plate 306, and the fan blades 303 are rotatably arranged on the outside of the mounting plate 308 through a torsion spring. After the second motor 307 is started, the output end of the second motor 307 will drive the rotation of the mounting plate 308, and the rotation of the mounting plate 308 will drive the rotation of the fan blades 303. The second motor 307 is assisted to provide power for the rotation of the fan blades 303, so that the rotation of the fan blades 303 is more stable and controllable.

[0043] The filter cover 301 is arranged at the lower end of the smoke collecting pipe 104, and the upper end of the smoke collecting pipe 104 is connected to the ventilation system. With the assistance of wind, the indoor air passes through the filter cover 301 and enters the filter cover 301, and then under the action of wind, the air is discharged from the smoke collecting pipe 104 to the ventilation system, thereby improving the convenience of equipment use.

[0044] During use of the present invention, the second motor 307 is started, and the output end of the second motor 307 drives the mounting plate 308 to rotate. The rotation of the mounting plate 308 drives the fan blades 303 to rotate. The rotation of the fan blades 303 generates an upward wind force. Under the action of the wind force, the indoor air passes through the filter cover 301 and enters the filter cover 301. Then, under the action of the wind force, the air enters the ventilation system along the smoke collecting pipe 104, thereby completing the discharge of the indoor air.

[0045] When a fire occurs indoors, the thick smoke generated by the fire will float to the top of the room. As the thick smoke passes through the filter cover 301 and enters the inside of the filter cover 301, the smoke concentration can be detected with the assistance of the smoke sensor to determine whether a fire occurs indoors. The smoke concentration in the direction of the fire is the highest through the joint action of multiple smoke sensors. Therefore, through the joint action of multiple smoke sensors, the device can determine the direction of the fire. Then the device accurately controls the first motor 107 to start, so that the output end of the first motor 107 rotates a fixed angle. The output end of the first motor 107 drives the transmission gear 108 to rotate. The rotation of the transmission gear 108 drives the gear ring to rotate through meshing, thereby rotating the turntable 201. The rotation of the turntable 201 turns the water spray pipe 202 to the direction of the fire. Then the device starts the electric control valve, and the water in the water supply system enters the connecting ring 101 through the water inlet pipe 106. Then the water in the connecting ring 101 is sprayed out through the water spray pipe 202. The water sprayed from the water spray pipe 202 assists in extinguishing the fire.

[0046] During the use of the present invention, the filter cover 301 is easily blocked by dust, thereby affecting the ventilation efficiency. When a fire occurs, impurities in the thick smoke are more likely to block the filter cover 301, reducing the ventilation efficiency of the device. At the same time, the water flow size sprayed by the water spray pipe 202 is constant, so that the coverage area of ​​the water spray is constant, thereby making the auxiliary fire extinguishing effect of the device poor. For this reason, the following technical solutions are proposed:

[0047] like Figures 1 to 6 As shown, the directional fire extinguishing assembly 2 is also provided with an adjusting assembly 4, with the assistance of the adjusting assembly 4, the water sprayed from the water spray pipe 202 is in a pulse state, thereby making the spraying area of ​​the water spray pipe 202 larger, which is conducive to fire extinguishing.

[0048] The adjusting component 4 includes a first annular hose 401, a second annular hose 402 is arranged on the water spray pipe 202, a connecting pipe 403 connected to the second annular hose 402 is arranged on the first annular hose 401, and the first annular hose 401 is located above the scraper 302. When the first annular hose 401 is squeezed, the air in the first annular hose 401 enters into the second annular hose 402 through the connecting pipe 403, so that the second annular hose 402 expands. When the second annular hose 402 expands, the inner diameter of the water spray pipe 202 becomes smaller, thereby changing the water spraying force of the water spray pipe 202, and thereby changing the spraying area of ​​the water spray pipe 202.

[0049] A scraper 302 that moves up and down is arranged on the outside of the filter cover 301, and an electromagnet is arranged on the scraper 302. A magnet block 304 is arranged on the fan blade 303. After the electromagnet is energized, when the fan blade 303 rotates, the magnet block 304 on the fan blade 303 will have a magnetic effect with the electromagnet on the scraper 302, thereby causing the scraper 302 to move upward. When the scraper 302 moves upward, it will squeeze the first annular hose 401, and there is a gap between two adjacent scrapers 302. When the fan blade 303 moves to the gap between two adjacent scrapers 302, the tops of the two adjacent scrapers 302 will not contact the first annular hose 401. Therefore, as the fan blade 303 rotates, the first annular hose 401 will be intermittently squeezed, so that the water spray from the water spray pipe 202 is in a pulsed state.

[0050] A fire extinguishing ball 203 is arranged at the end of the water spray pipe 202, and a groove 204 is arranged at the side end of the fire extinguishing ball 203. A plug rod 205 is arranged on the side of the water spray pipe 202 close to the ventilation component 3, and a spring 206 is arranged between the plug rod 205 and the water spray pipe 202. The plug rod 205 is magnetic. After the electromagnet is energized, there is a magnetic attraction between the electromagnet on the scraper 302 and the magnetic plug rod 205, so that the plug rod 205 overcomes the action of the spring 206 and moves away from the groove 204. When the plug rod 205 leaves the groove 204, the fire extinguishing ball 203 is sprayed out under the action of the water flow in the water spray pipe 202. When the fire extinguishing ball 203 hits the fire location, an explosion will occur. Flame retardant liquid is arranged in the fire extinguishing ball 203. Therefore, the flame retardant liquid in the fire extinguishing ball 203 is discharged to enhance fire extinguishing, thereby improving the fire extinguishing effect of the equipment.

[0051] The water spray pipe 202 is fixed on the turntable 201, a connecting frame 208 is arranged on the outside of the turntable 201, and the first annular hose 401 is arranged at the lower end of the connecting frame 208. When the turntable 201 rotates, the water spray pipe 202 and the first annular hose 401 will be driven to rotate, so that the equipment is more stable and controllable during use.

[0052] A slide groove 309 is arranged on the outside of the filter cover 301, and the two sides of the scraper 302 slide in the slide groove 309. The scraper 302 slides in the slide groove 309, which makes the sliding of the scraper 302 more convenient and improves the convenience of using the equipment.

[0053] During use of the present invention, after the second motor 307 is started, the rotation of the fan blades 303 generates wind force. When the room is ventilated under the action of the wind force, if a fire occurs in the room, thick smoke will be generated. Therefore, during the ventilation process of the device, the smoke sensor will detect the smoke concentration in the filter cover 301. When the detection value of the smoke sensor exceeds the threshold, it indicates that a fire has occurred in the room. Through the synergistic analysis of multiple smoke sensors, the one with the largest detection value of the multiple smoke sensors is the direction of the fire. Therefore, the device controls the first motor 107 to start, rotate the turntable 201, and thus rotate the water spray pipe 202 to the direction of the fire, and then start the electric control valve to enable the water spray pipe 202 to spray water in a directional manner to extinguish the fire.

[0054] As the water spray pipe 202 sprays water to extinguish the fire, if the fire is extinguished, the detection value of the smoke sensor will gradually decrease. If the fire is not extinguished, the detection value of the smoke sensor will remain unchanged or continue to increase.

[0055] When the detection value of the smoke sensor remains unchanged, the device determines that the indoor fire has not been extinguished. At this time, the electromagnet on the scraper 302 is energized. After the electromagnet is energized, a magnetic field is generated. A magnetic force is generated between the electromagnet and the magnet block 304 on the fan blade 303. On the one hand, under the influence of the magnetic force, the inclination angle of the fan blade 303 will increase. At this time, as the fan blade 303 rotates, the wind force generated by the fan blade 303 will be strengthened. After the wind force is strengthened, the device can better exhaust smoke from the room. On the other hand, under the influence of the magnetic force, during the rotation of the fan blade 303, when the fan blade 303 moves close to the scraper 302, due to the influence of the magnetic force, the scraper 302 will move upward, and when the fan blade 303 moves away from the scraper 302, due to the influence of gravity, the scraper 302 will move downward, thereby causing the scraper 302 to move up and down, and the up and down movement of the scraper 302 will scrape off impurities on the filter holes of the filter cover 301 to ensure the stability of the smoke exhaust of the device.

[0056] During the rotation of the fan blade 303, as the fan blade 303 approaches the scraper 302, the inclination angle of the fan blade 303 will gradually increase, and as the fan blade 303 moves away from the scraper 302, the inclination angle of the fan blade 303 will gradually decrease. There is a gap between two adjacent scrapers 302. Therefore, the inclination angle of the fan blade 303 will change back and forth, thereby making the wind force generated by the rotation of the fan blade 303 in a pulsed state. When the pulsed wind force acts on the filter cover 301, it is beneficial to clear the filter holes on the filter cover 301, thereby improving the fluency of smoke exhaust of the equipment.

[0057] While the scraper 302 moves up and down, the scraper 302 will squeeze the first annular hose 401, and there will be a gap between two adjacent scrapers 302. When the fan blade 303 moves to the gap between the two adjacent scrapers 302, the tops of the two adjacent scrapers 302 will not contact the first annular hose 401. Therefore, as the fan blade 303 rotates, the first annular hose 401 will be intermittently squeezed, so that the water spray of the water spray pipe 202 is in a pulsed state, thereby increasing the water spraying area of ​​the water spray pipe 202, which is beneficial for the equipment to extinguish fires.

[0058] When the detection value of the smoke sensor gradually increases, the device determines that the fire in the room is expanding. At this time, the device controls the current of the electromagnet to increase, so the magnetic field of the electromagnet will be strengthened, and the device will generate stronger wind force to exhaust smoke.

[0059] At the same time, when the current flowing through the electromagnet increases, the magnetic force between the electromagnet and the magnetic rod 205 will also increase, thereby enabling the rod 205 to overcome the action of the spring 206 and move away from the groove 204. After the rod 205 leaves the groove 204, the fire extinguishing ball 203 is sprayed out under the action of the water flow in the water pipe 202. When the fire extinguishing ball 203 hits the fire location, an explosion will occur. Flame retardant liquid is provided in the fire extinguishing ball 203. Therefore, the flame retardant liquid in the fire extinguishing ball 203 is discharged to enhance fire extinguishing, thereby improving the fire extinguishing effect of the equipment.

[0060] The present invention is often installed indoors with multiple devices. Once a fire occurs indoors, the detection values ​​of multiple smoke sensors in the equipment located at the top of the fire position are close, so the first motor 107 of the device will keep running, so that the turntable 201 will keep rotating, and the water pipe 202 can spray all around to assist in fire extinguishing. In addition, multiple devices are connected to each other based on the Internet of Things, so that when the values ​​detected by the smoke sensors in the equipment around the fire do not reach the threshold, corresponding operations will be performed, so that the water pipes 202 of the equipment around the fire will turn to the direction of the fire to spray water.

[0061] The main functions achieved by the present invention are: by setting up components such as smoke sensors, magnet blocks 304, electromagnets, scraper plates 302, torsion springs and first annular hoses 401, when the device detects a fire in the room with the assistance of the smoke sensor, the electromagnet is energized to change the inclination angle of the fan blades 303, thereby causing the device to generate pulse wind force, which is beneficial for clearing the filter cover 301. After the electromagnet is energized, as the fan blades 303 rotate, the magnet blocks 304 interact with the electromagnet to cause the scraper plates 302 to move up and down, thereby clearing the filter cover 301. The scraper 302 moves up and down to intermittently squeeze the first annular hose 401, so that the water flow sprayed from the sprinkler pipe 202 is in a pulsed state, and the water spraying area of ​​the sprinkler pipe 202 is increased, thereby enhancing its fire extinguishing effect. When the fire in the room is detected to be increasing with the assistance of the smoke sensor, the current of the electromagnet is increased, thereby canceling the limit of the fire extinguishing ball 203. Therefore, the fire extinguishing ball 203 will be sprayed out with the water flow, so that the fire extinguishing ball 203 hits the fire location, and the flame retardant liquid in the fire extinguishing ball 203 is discharged to assist in fire extinguishing, thereby improving the fire extinguishing effect of the equipment.

[0062] The present invention also provides a control method for a distributed fire prevention and control device based on the Internet of Things, comprising the following steps:

[0063] Step 1: Start the second motor 307 to rotate the fan blades 303, thereby generating upward wind force in the device, so that the device can ventilate and exhaust the room;

[0064] Step 2: When a fire occurs indoors, the detection value of the smoke sensor in the device will increase during the process of ventilating and exhausting the indoor air, thereby causing the device to determine that a fire has occurred indoors;

[0065] Step 3: Based on step 2, the device determines the specific location of the fire according to the cooperation of multiple smoke sensors, and controls the water spray pipe 202 to turn to the direction of the fire, and makes the water spray pipe 202 spray water to extinguish the fire;
