Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, and in particular to a fire alarm device and alarm method for ultra-high-rise buildings. Background Technology

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. Cables play a very important role in the power supply and information transmission of high-rise buildings. However, cables are prone to catching fire and causing fires due to prolonged use or external factors. Therefore, cable fire alarms are now required to be installed on cables in high-rise buildings.

[0003] Currently, high-rise building cable fire alarms on the market have complex structures, are inconvenient to install and disassemble, and some alarms are even inaccurate in their monitoring. At the same time, monitoring personnel cannot know the temperature information of the cable in real time, which affects the protection of the cable.

[0004] Chinese Patent No. CN210488732U discloses a fire alarm and protection device for cables in high-rise buildings. It utilizes a power supply, controller, alarm, and temperature sensor inside the cavity. The controller is equipped with a power conversion module, a data receiving and processing module, a control module, and a wireless transmission module. The data receiving and processing module can receive and process the temperature signal from the temperature sensor, the control module can control the operation of the alarm, and the wireless transmission module can transmit digital temperature signals to the back-end display platform. Monitoring personnel can understand the real-time status of the cable through the back-end display platform, thereby protecting the cable in a timely and effective manner.

[0005] Although the device can detect the temperature of the internal cable of the alarm in real time and trigger an alarm, allowing monitoring personnel to understand the situation in real time through the backend, the device has many built-in electronic component modules. When the device is running, if the internal temperature is too high and heat is not dissipated in time, it can easily cause the internal temperature to be too high, resulting in cable aging and damage to electronic components, which will affect the service life of the equipment.

[0006] Therefore, a fire alarm device and alarm method for ultra-high-rise buildings are proposed. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 6 The present invention provides a technical solution:

[0037] A fire alarm device for ultra-high-rise buildings includes an alarm body 1. Mounting ears 11 are fixed at all four corners of the outer surface of the alarm body 1. A cable insertion slot is provided on the rear end face of the alarm body 1. A display screen and buttons for controlling the content displayed on the display screen are provided on the front end face of the alarm body 1. A sensor is installed inside the alarm body 1. A second rotating groove 13 is provided on the lower end face of the alarm body 1. A heat dissipation mechanism 2 is provided inside the second rotating groove 13. Rotating grooves 12, communicating with the second rotating groove 13, are provided on both sides of the second rotating groove 13. A drive mechanism 3 is installed inside the first rotating groove 12.

[0038] The heat dissipation mechanism 2 includes a sleeve 21 rotatably connected in the rotating groove 13, and heat dissipation blades 22 are fixed inside the sleeve 21. The sleeve 21 is driven by the driving mechanism 3 to rotate the heat dissipation blades 22 to achieve heat dissipation and cooling by alternating hot and cold air inside the alarm body 1 with outside air.

[0039] By adopting the above technical solution, this application designs a drive mechanism 3 in conjunction with a heat dissipation mechanism 2 to drive the heat dissipation mechanism 2 to operate, so that the internal air of the alarm body 1 and the external air alternate between hot and cold to achieve temperature regulation inside the alarm body 1, thereby cooling and dissipating heat, maintaining a suitable working environment for the electronic equipment inside the alarm body 1, extending the service life of the alarm body 1 and the sensitivity of related electronic components.

[0040] Specifically, such as Figure 1 and Figure 2 as well as Figure 6 As shown, a filter mechanism 4 is provided on the upper side of the heat dissipation mechanism 2. The filter mechanism 4 is connected to the heat dissipation mechanism 2. The filter mechanism 4 can dry and filter the air driven into the alarm body 1 by the heat dissipation mechanism 2, reducing the humidity and dust inside the alarm body 1. The filter mechanism 4 includes a U-shaped heating plate 5 fixed inside the alarm body 1. A filter screen is sleeved on the outside of the heating plate 5. The lower side of the filter screen is connected to the drive mechanism 3. The lower side of the filter screen has a V-shaped structure design. The filter screen includes an upper filter screen 41 and a lower filter screen 42. Several carbon fiber skeletons 43 are inclinedly fixed between the upper filter screen 41 and the lower filter screen 42. Silica gel desiccant 44 is filled between adjacent carbon fiber skeletons 43.

[0041] By adopting the above technical solution, the conveyor shaft 31 drives the filter screen to move around the heating plate 5, so that the filter screen can fully contact and filter the air entering the alarm body 1. In addition, the filter screen has a built-in silica gel desiccant 44, which can further dry the air passing through the filter screen.

[0042] Specifically, such as Figure 2As shown, the heating plate 5 is made of copper and has a built-in heating wire, which is electrically connected to the control module installed in the alarm body 1.

[0043] By adopting the above technical solution, the heating plate 5 is heated by controlling the heating wire inside the heating plate 5, thereby further heating the inside of the alarm body 1 to achieve further drying of the internal air.

[0044] Specifically, such as Figure 4 and Figure 5 As shown, the drive mechanism 3 includes motors 33 symmetrically mounted on both sides of the sleeve 21. The upper output shaft of the motor 33 extends into the interior of the rotating groove 12, and a gear 34 is rotatably connected inside the rotating groove 12. A gear ring 35 is sleeved and fixed on the outside of the sleeve 21 at a position corresponding to the gear 34. The gear ring 35 is located inside the rotating groove 12, and the gear 34 and the gear ring 35 are meshed and connected for transmission.

[0045] By adopting the above technical solution, during operation, the control module controls the motor 33 to run. The motor 33 drives the gear 34 to rotate, which causes the gear ring connected to the gear 34 to drive the sleeve 21 to rotate in the rotating groove 13. The rotation of the sleeve 21 will drive the heat dissipation blades 22 located inside the sleeve 21 to rotate. At this time, the outside air is delivered to the inside of the alarm body 1 through the lower opening of the sleeve 21 under the rotation of the heat dissipation blades 22, realizing the alternating cooling and heat dissipation of the inside of the alarm body 1.

[0046] Specifically, such as Figure 4 and Figure 5 As shown, the drive mechanism 3 also includes a gear ring 37 fixed on the upper end face of the sleeve 21. A conveying shaft 31 is attached to the lower inner side of the filter screen, and a rotating shaft 32 is fixed to the rear end of the conveying shaft 31. The rotating shaft 32 passes through the inner wall of the alarm body 1 and is rotatably connected to the inner wall of the alarm body 1. A gear 36 is fixed to the front end of the conveying shaft 31, and the gear 36 meshes with the gear ring 37 for transmission.

[0047] By adopting the above technical solution, and during the rotation of the sleeve 21, the gear ring 2 37 meshes with the gear 2 36 to drive the conveyor shaft 31 to rotate. The conveyor shaft 31 drives the filter screen to move around the heating plate 5, so that the filter screen can fully contact and filter the air entering the alarm body 1. In addition, the filter screen has a built-in silica gel desiccant 44, which can further dry the air passing through the filter screen.

[0048] Specifically, such as Figure 2 As shown, inside the main body 1 of the alarm device, scrapers are symmetrically fixed on the lower side of the filter screen, and the scrapers are in contact with the outer surface of the lower filter screen 42 in the filter screen.

[0049] By adopting the above technical solution, and before the heat dissipation mechanism 2 is operated, it is necessary to control the motor 33 to rotate forward and reverse intermittently five times to realize the forward and reverse displacement of the filter screen outside the heating plate 5, and to scrape and clean the filter screen by the scraper.

[0050] A method for fire alarm in ultra-high-rise buildings includes the following steps:

[0051] S1: The main body of the alarm 1 has a built-in temperature sensor, humidity sensor, and a sensor and control module that are connected to the cable in real time. The control module is electrically connected to the temperature sensor, humidity sensor, sensor, display screen and buttons respectively. The user controls the control module through the buttons to display the relevant sensor feedback values ​​on the display screen.

[0052] S2: When the real-time feedback value from the sensor exceeds the preset value, an alarm will be triggered, prompting the back-end personnel to inspect and repair. When the feedback temperature and humidity exceed the predetermined values, the heat dissipation mechanism 2 and the filtration mechanism 4 will be automatically activated. During operation, the control module controls the motor 33 to run. The motor 33 drives the gear 1 34 to rotate, causing the gear ring connected to the gear 1 34 to drive the sleeve 21 to rotate in the rotating groove 2 13. The rotation of the sleeve 21 will drive the heat dissipation fins 22 located inside the sleeve 21 to rotate. At this time, the outside air is delivered to the interior of the alarm body 1 through the lower opening of the sleeve 21 under the rotation of the heat dissipation fins 22, realizing the alternating cooling and heat dissipation of the interior of the alarm body 1. During the rotation of the sleeve 21, the gear ring 2 37 meshes with the gear 2 36 to drive the conveyor shaft 31 to rotate. The conveyor shaft 31 drives the... The filter screen moves around the heating plate 5, allowing it to fully contact and filter the air entering the alarm body 1. The filter screen contains silica gel desiccant 44, which further dries the air passing through it. When the humidity inside the alarm body 1 is high, the heating plate 5 can be heated by controlling the heating wire inside, further drying the air inside the alarm body 1. This also dries the silica gel desiccant 44 inside the filter screen, extending its lifespan and eliminating the need for frequent filter replacements. Before the heat dissipation mechanism 2 operates, the motor 33 needs to rotate five revolutions in both forward and reverse directions to move the filter screen around the heating plate 5, allowing it to be cleaned by scraping with a scraper.

[0053] S3: The filter mechanism 4 and the heat dissipation mechanism 2 operate synchronously to regulate the humidity and temperature inside the alarm body 1, ensuring a suitable working environment inside the alarm body 1 and improving the service life of the internal electronic equipment.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
