Description

Technical Field

[0001] This application relates to the field of fire safety technology, specifically a ventilation device. Background Technology

[0002] Fire safety is short for fire prevention and firefighting. It is a specialized field of work that has gradually formed and developed in the process of humankind's struggle against fire, focusing on fire prevention and extinguishing, and serving a social safety guarantee purpose. Ventilation systems play a crucial role in prevention and initial firefighting efforts.

[0003] For example, the Chinese utility model patent with announcement number "CN216048186U" discloses a fire safety ventilation device. In this utility model, during installation, the sliding connecting rods on both sides of the fixed connecting frame are inserted into the corresponding rectangular sliding grooves. The telescopic connecting rod is manually pushed inward a certain distance, and then the fixed connecting frame is placed at the corresponding position on the ceiling. The corresponding telescopic connecting rod is then slowly released; under the action of the spring, the telescopic connecting rod will extend again and lock into the edge of the adjacent ceiling. This method secures the remaining four corners to the ceiling. Secondly, in the event of a fire, the smoke alarm will be triggered, controlling the controller, which in turn controls the motor. Thirdly, the motor drives the gears to rotate via the shaft, causing the arc-shaped rack to move downwards. During this downward movement, the adjustable duct rotates around one side of the shaft at a certain angle, so that the opening faces the top of the corridor. Fourthly, the exhaust fan absorbs the smoke and dust from the opening of the adjustable duct through the flexible hose.

[0004] Although the aforementioned patent includes a smoke detector, when a fire occurs, relying solely on the exhaust fan to remove smoke and dust is not only insufficient for effective initial firefighting efforts, but also allows outdoor oxygen to enter the room, leading to a further escalation of the disaster.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Reference Figure 1 and Figure 2This application provides a ventilation device, including a housing 1, a mounting plate 101, and a temperature sensor 103. The housing 1 is equipped with a ventilation mechanism 2 and a water spraying mechanism 3. A louvered fan 4 is rotatably connected to the bottom of the housing 1. The ventilation mechanism 2 includes a filter plate 203, and the water spraying mechanism 3 includes a guide pipe 314 and a water pump 317. The mounting plate 101 is fixedly installed on the outer side of the upper end of the housing 1. The surface of the mounting plate 101 is provided with a threaded hole 102. The temperature sensor 103 is fixedly installed on one side of the inner wall of the housing 1. The ventilation mechanism 2 draws in and exhausts indoor air to achieve the effect of air circulation. When the temperature sensor 103 senses an abnormal indoor temperature, the water spraying mechanism 3 can spray water to extinguish the abnormal temperature.

[0037] Reference Figure 3 and Figure 4 In one aspect of this embodiment, the water spraying mechanism 3 further includes a fixing block 301, which is fixedly installed on the top of the inner wall of the housing 1. A first motor 302 is fixedly installed at one end of the fixing block 301, and a first gear 303 is fixedly connected to one end of the first motor 302. The output shaft of the first motor 302 is fixedly connected to the first gear 303. A second gear 305 is rotatably connected to the lower surface of the fixing block 301, and a threaded rod 304 is fixedly installed at one end of the second gear 305.

[0038] The threaded rod 304 has a threaded connection to a slider 306. A limit plate 308 is fixedly installed at the lower end of the threaded rod 304. A slide rod 307 is fixedly connected to the lower surface of the fixed block 301. The slider 306 is slidably connected to the surface of the slide rod 307. The limit plate 308 is fixedly installed at the lower end of the slide rod 307. There are multiple limit plates 308 and sliders 306.

[0039] A connecting plate 309 is fixedly installed on one side of the slider 306. A second motor 313 is fixedly installed on one side of the connecting plate 309. A rotating rod 312 is fixedly connected to one end of the second motor 313. The output shaft of the second motor 313 is fixedly connected to the rotating rod 312. A limit block 311 is rotatably connected to the surface of the rotating rod 312. A fixing rod 310 is fixedly installed on the upper surface of the limit block 311.

[0040] A water supply hose 316 is fixedly installed on the surface of the rotating rod 312, and a water pump 317 is fixedly installed on the upper surface of the housing 1.

[0041] The guide pipe 314 is fixedly installed at the lower end of the rotating rod 312. A water spray hole 315 is fixedly installed on the lower surface of the guide pipe 314. A fixing block is provided at one end of the first motor 302 and at the upper ends of the threaded rod 304 and the sliding rod 307. When the first motor 302 is started, its output shaft drives the first gear 303, which is fixedly connected to it, to rotate. When the first gear 303 rotates, it meshes with the second gear 305, thereby driving the threaded rod 304 to rotate. The threaded rod 304 then drives the slider 306, which is threadedly connected to its surface, to descend. When the slider 306 descends, it drives the sliding block 306, which is threadedly connected to its surface, to descend. Simultaneously, the slider 306 descends, causing the guide pipe 314 installed below the slider 306 to descend as well. After descending to a certain height, the second motor 313 is activated. The output shaft of the second motor 313 drives the rotating rod 312, which is fixedly connected to it, to rotate, and at the same time, drives the guide pipe 314, which is fixedly installed at the lower end of the rotating rod 312, to rotate. After rotating to a suitable angle, the second motor 313 is turned off, and the water pump 317 is activated. The water pump 317 draws water from the external water source and transports it through the water delivery hose 316 fixedly installed on the surface of the rotating rod 312 to the water spray hole 315 for spraying water to extinguish the abnormal temperature.

[0042] Reference Figure 1 and Figure 2 In one aspect of this embodiment, the ventilation mechanism 2 includes a ventilation pipe 201, which is fixedly installed on the top of the inner wall of the housing 1. A first fan 202 is fixedly installed at the bottom of the inner wall of the ventilation pipe 201. A filter plate 203 is fixedly installed inside the ventilation pipe 201. A second fan 204 is fixedly installed at the top of the inner wall of the ventilation pipe 201. The effect of air circulation is achieved by activating the first fan 202 and the second fan 204 to draw in and exhaust indoor air.

[0043] refer to Figure 5 and Figure 6 In one aspect of this embodiment, the louvered fan 4 includes a rotating shaft 401, which is rotatably connected to the bottom of the inner wall of the housing 1. Fan blades 402 are fixedly mounted on the surface of the rotating shaft 401. A belt 403 is rotatably connected to each pair of rotating shafts 401. The louvered fan 4 also includes a third motor 404, which is fixedly mounted on one side of the housing 1. The output shaft of the third motor 404 is fixedly connected to the rotating shaft 401. By starting the third motor 404, the third motor 404 drives the rotating shaft 401, which is fixedly connected to its output shaft, to rotate. Then, the belt 403 drives all the rotating shafts to rotate, causing the fan blades 402 fixedly mounted on the surface of the output shaft to rotate, thereby opening or closing the louvered fan 4.

[0044] All electrical devices in this plan are powered by an external power source.

[0045] Working principle: When using this ventilation device, it should first be fixedly installed on the ceiling through the threaded holes 102 on the surface of the mounting plate 101. Then, start the No. 3 motor 404, which drives the rotating shaft 401 fixedly connected to its output shaft to rotate. Then, the belt 403 drives all the rotating shafts to rotate, causing the fan blades 402 fixedly installed on the surface of the output shaft to rotate, thus opening the louvered fan 4. After opening, start the No. 1 fan 202 and the No. 2 fan 204 to draw in and exhaust indoor air to achieve the effect of air circulation. A temperature sensor 103 is fixedly installed on one side of the inner wall of the housing 1. When the temperature sensor 103 senses an abnormal indoor temperature, it starts the No. 1 motor 302. The output shaft of the No. 1 motor 302 drives the No. 1 gear 303 fixedly connected to it to rotate. When the No. 1 gear 303 rotates, it interacts with the No. 2 gear 301. 5. The meshing rotation drives the threaded rod 304 to rotate, which in turn drives the slider 306 threadedly connected to its surface to descend. When the slider 306 descends, it drives other sliders 306 slidably connected to the surface of the slide rod 307 to descend simultaneously, causing the guide pipe 314 installed below the slider 306 to descend. After descending to a certain height, the second motor 313 is started. The output shaft of the second motor 313 drives the rotating rod 312 fixedly connected to it to rotate, which in turn drives the guide pipe 314 fixedly installed at the lower end of the rotating rod 312 to rotate. After rotating to a suitable angle, the second motor 313 is turned off, and the water pump 317 is started. The water pump 317 draws water from the external water source and transports the water through the water delivery hose 316 fixedly installed on the surface of the rotating rod 312 and through the guide pipe 314 to the spray hole 315 for spraying water to extinguish the abnormal temperature.
