Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, and in particular to a fire alarm device. Background Technology

[0002] With the acceleration of urbanization and industrial development, the number of buildings and facilities is constantly increasing, and the risk of fire is also rising. Large commercial complexes, high-rise buildings, factories, warehouses and other places are densely populated with people and concentrated with materials. Once a fire occurs, the consequences are unimaginable. At the same time, the widespread use of electrical equipment in modern society and the storage and transportation of flammable and explosive materials have also increased the possibility of fire. Therefore, a fire alarm device is needed to detect fires and issue alarm signals.

[0003] Fire alarms have stringent requirements for the installation environment in actual installation scenarios. For example, the material and flatness of the wall surface can affect the smooth progress of the installation. In some older buildings, the wall surface may be uneven or there may be a lot of wiring and pipes already laid, making it extremely difficult to find a suitable installation location. Moreover, different wall materials, such as brick walls, concrete walls, or wooden wall panels, require different installation tools and fixing accessories, which undoubtedly increases the complexity of the pre-installation preparation work. When the fire alarm needs to be repositioned or maintained later, since its installation method is usually relatively fixed, the disassembly process may cause some damage to the alarm itself, causing great inconvenience to the user.

[0004] Therefore, considering the stringent environmental requirements of wall materials and flatness for the actual installation of fire alarms, the difficulty in finding suitable installation locations due to uneven walls and numerous existing wiring and conduits in old buildings, and the potential for damage to the alarm due to fixed installation methods during adjustments and maintenance, which causes inconvenience to users, a new type of alarm can be designed. This new alarm provides multiple installation methods through the mounting slots on the fire alarm mounting bracket, along with threaded nails, T-shaped inserts, suction cups, and fastening nuts. The T-shaped inserts further expand the installation area of ​​the alarm mounting bracket, allowing for the most suitable installation method for the alarm components, whether in narrow corners, high ceilings, or special locations near ventilation openings, thus improving the environmental adaptability and overall performance of the alarm components. Utility Model Content

[0005] To overcome the problems caused by the stringent environmental requirements of wall material and flatness in the actual installation of fire alarms, the difficulty in finding installation sites due to uneven walls and numerous existing wiring and pipes in old buildings, and the risk of damage to the alarm due to the fixed installation method during adjustment and maintenance, which brings inconvenience to users.

[0006] The technical solution of this utility model is as follows: a fire alarm device, including an alarm component; and an alarm mounting bracket, wherein the rear end of the alarm component is equipped with an alarm mounting bracket for providing multiple installation methods and giving the alarm component good support. The alarm mounting bracket includes a threaded connection hole, a primary mounting groove, a secondary mounting groove, a primary threaded nail, a secondary threaded nail, a fastening nut, a locking post, a suction cup, a slot, and a T-shaped insert plate; a locking post is installed at the center of the bottom end of the alarm mounting bracket, and a suction cup is installed at the bottom end of the locking post.

[0007] Preferably, the threaded connection hole can be connected to the wall or other fixed surface through primary and secondary threaded screws. This method is relatively simple to operate, and the installer only needs to use common installation tools such as electric drills and screwdrivers to complete the installation process. At the same time, the primary and secondary mounting slots provide more installation options. When space is limited or a specific angle installation is required, the mounting slot can be used with a T-shaped insert to flexibly adjust the installation angle and position, meeting the needs of visibility and operability of the alarm component in different scenarios. The combination of the clamp and the suction cup provides a quick and temporary installation method, and the fastening nut and thread are used to secure the connection. The screws enhance the stability of the installation. Even when encountering external factors such as vibration or wind, the tightening nuts prevent the screws from loosening, ensuring that the alarm components will not fall off or shift due to insecure installation. The locking posts provide a stable support structure for the suction cup, allowing the suction cup to evenly distribute the force while bearing the weight of the alarm components, thus enhancing the reliability of adsorption. Especially on smooth surfaces with high humidity or slight unevenness, the support of the locking posts helps the suction cup to better adhere to the surface, improving the adsorption force and ensuring that the alarm components can be stably installed in the predetermined position under various environmental conditions, enabling them to perform their alarm function promptly and accurately.

[0008] Preferably, the alarm mounting bracket has a slot for mounting the pin at the center of the bottom end, a threaded connection hole at the center of the top end, and two sets of primary mounting slots and two sets of secondary mounting slots symmetrically through the four edges of the top end. Multiple sets of primary threaded pins are installed on the two sets of primary mounting slots on the alarm mounting bracket. The primary threaded pins pass through the primary mounting slots, and a fastening nut is installed at the bottom end of the primary threaded pins.

[0009] Preferably, the top of the alarm mounting bracket is equipped with two sets of T-shaped inserts that pass through two sets of secondary mounting slots. Two sets of symmetrical threaded holes are opened through the bottom of each T-shaped insert, and secondary threaded pins are installed on each T-shaped insert in the threaded holes.

[0010] Preferably, the alarm assembly includes a mounting plate, a smoke sensor, a microcontroller, a transmitter, an audible and visual buzzer, a protective cover, a battery compartment, a compartment cover, and a threaded connecting post; a square mounting groove is provided at the center of the top of the mounting plate.

[0011] Preferably, a smoke sensor is installed in the center of the square mounting slot on the mounting plate, and an audible and visual buzzer is installed below the smoke sensor in the square mounting slot on the mounting plate.

[0012] Preferably, a microcontroller is installed above the smoke sensor in the square mounting slot of the mounting plate, and a transmitter is installed on one side of the microcontroller in the square mounting slot of the mounting plate.

[0013] Preferably, a protective cover is fitted on the top of the mounting plate, and a circular mounting groove is opened at the center of the top of the protective cover. The top of the smoke sensor passes through the protective cover. A threaded connecting post is installed at the center of the bottom of the mounting plate. The mounting plate is connected to the threaded connecting hole of the alarm mounting bracket through the threaded connecting post. A battery compartment is opened at the bottom of the mounting plate below the threaded connecting post, and a compartment cover is installed on the top of the battery compartment.

[0014] The beneficial effects of this utility model are:

[0015] 1. Existing fire alarms often lack effective adaptation methods when facing different wall materials. The alarm mounting bracket of this utility model, through threaded connection holes, primary mounting slots, primary threaded nails, and fastening nuts, can find a suitable installation method for wall materials such as brick walls, concrete walls, and wooden wall panels. For old building walls with poor flatness, the primary mounting slot can flexibly adjust the installation position to avoid uneven areas and existing wiring pipes. Compared with the fixed installation method of the existing technology, which cannot be adjusted, it greatly improves the possibility of finding a suitable installation position. Moreover, the combination of the clamping column and suction cup can be used for quick installation on smooth walls without drilling or other complicated operations, providing users with more options. In terms of later maintenance, the installation method of the existing technology is fixed, and disassembly is prone to damage to the alarm. With the connection method of threaded connection column and threaded connection hole, disassembly only requires a simple screwing operation, which is convenient, quick, and does not easily damage the alarm. Moreover, when it is necessary to adjust the position, the alarm mounting bracket's rich mounting slots and T-shaped inserts can easily change the installation angle and position without re-drilling or large-scale disassembly and installation work, effectively solving the problem of difficult adjustment and maintenance in the existing technology.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: a fire alarm device, including an alarm component and an alarm mounting bracket 2. The alarm component has an alarm mounting bracket 2 installed at its rear end, providing multiple installation options and good support. The alarm mounting bracket 2 includes a threaded connection hole 201, a primary mounting groove 202, a secondary mounting groove 203, a primary threaded nail 204, a secondary threaded nail 205, a fastening nut 206, a locking post 207, a suction cup 208, a slot 209, and a T-shaped insert 210. A locking post 207 is installed at the center of the bottom end of the alarm mounting bracket 2, and a suction cup 208 is installed at the bottom end of the locking post 207. The threaded connection hole 201 can be connected to a wall or other fixed surface through the primary threaded nail 204 and the secondary threaded nail 205. This method is relatively simple to operate; construction personnel only need to use common installation tools such as electric drills and screwdrivers to complete the installation process. At the same time, the primary mounting groove 202 and the secondary mounting groove 203 provide more installation options. When space is limited or a specific angle of installation is required, the mounting slot can be used with the T-shaped insert 210 to flexibly adjust the installation angle and position, meeting the needs of visibility and operability of the alarm component in different scenarios. The combination of the locking post 207 and the suction cup 208 provides a quick and temporary installation method. The cooperation between the fastening nut 206 and the threaded nail enhances the stability of the installation. Even when encountering external factors such as vibration and wind, the fastening nut 206 can prevent the threaded nail from loosening, ensuring that the alarm component will not fall off or shift due to insecure installation. The locking post 207 provides a stable support structure for the suction cup 208, allowing the suction cup 208 to evenly distribute the force while bearing the weight of the alarm component, enhancing the reliability of adsorption. Especially on smooth surfaces with high humidity or slight unevenness, the support of the locking post 207 helps the suction cup 208 to better adhere to the surface, improving the adsorption force and ensuring that the alarm component can be stably installed in the predetermined position under various environmental conditions, so as to perform the alarm function in a timely and accurate manner.

[0024] Please see Figures 1-5In this embodiment, the alarm mounting bracket 2 has a slot 209 at the center of its bottom for mounting the pin 207, and a threaded connection hole 201 at the center of its top. Two sets of primary mounting slots 202 and two sets of secondary mounting slots 203 are symmetrically arranged around the perimeter of the top of the alarm mounting bracket 2. Multiple sets of primary threaded nails 204 are installed on the two sets of primary mounting slots 202 on the alarm mounting bracket 2. Each primary threaded nail 204 passes through the primary mounting slot 202, and a fastening nut 206 is installed at the bottom of each primary threaded nail 204. During installation, the design of the mounting slots provides a convenient operating method for construction personnel. Construction personnel can freely adjust the position of the threaded nails within a certain range according to the actual situation, without the need for precise measurement and positioning, greatly improving installation efficiency. In later maintenance, if it is necessary to adjust the alarm... Disassembly or replacement is possible by loosening the fastening nut 206 to easily remove the alarm mounting bracket 2, avoiding large-area damage to the wall. The slot 209 facilitates the installation and removal of the clamping post 207. When the suction cup 208 is needed for installation assistance or replacement, the operation can be performed quickly, improving the flexibility and maintainability of the equipment. The top of the alarm mounting bracket 2 is equipped with two sets of T-shaped inserts 210 that pass through two sets of secondary mounting slots 203. Two sets of symmetrical threaded holes are opened through the bottom of each T-shaped insert 210. Secondary threaded nails 205 are installed on each T-shaped insert 210 at the threaded holes. The cooperation between the T-shaped inserts 210 and the secondary mounting slots 203 provides more flexibility for installation. The T-shaped inserts 210 can slide and adjust within a certain range within the secondary mounting slots 203 to adapt to different installation layout requirements.

[0025] Please see Figures 2-3 In this embodiment, the alarm component includes a mounting plate 101, a smoke sensor 102, a microcontroller 103, a transmitter 104, an audible and visual buzzer 105, a protective cover 106, a battery compartment 107, a compartment cover 108, and a threaded connecting post 109. A square mounting groove is provided at the center of the top of the mounting plate 101. The square mounting groove provides a stable foundation structure for the installation of each component, ensuring that the components will not shift or loosen due to vibration, collision, or other reasons during daily use, thus affecting the normal operation of the equipment. The smoke sensor 102 is installed in the center of the square mounting groove on the mounting plate 101. The smoke sensor 102 is an MQ-2. An audible and visual buzzer 105 is installed below the smoke sensor 102 in the square mounting groove on the mounting plate 101. The audible and visual buzzer 105 is an LTE-1101J. Placing the smoke sensor 102 in the center position is beneficial for it to capture smoke particles in the air from all directions. Since the diffusion of smoke in space is irregular, the central layout allows the sensor to receive smoke information from all directions to the greatest extent and reduce detection blind spots.

[0026] Please see Figures 2-3 In this embodiment, a microcontroller 103, using an STM32F103, is installed above the smoke sensor 102 in the square mounting slot of the mounting plate 101. A transmitter 104, using a SIM800L, is installed to one side of the microcontroller 103 in the square mounting slot of the mounting plate 101. Placing the microcontroller 103 above the smoke sensor 102 allows for faster signal reception from the sensor. Due to the close proximity and short signal transmission path, signal attenuation and interference during transmission are reduced, enabling the microcontroller 103 to process and analyze smoke data promptly. In the instant a fire occurs, it can quickly determine whether the smoke concentration change has reached the alarm threshold, greatly improving the timeliness and accuracy of the alarm. The transmitter 104 is installed close to the microcontroller 103. When the microcontroller 103 determines that an alarm is needed, it can quickly transmit the alarm command to the transmitter 104. The transmitter 104 can then quickly send fire information to relevant monitoring centers, fire departments, or users' mobile devices. The mounting plate 101 is equipped with a protective cover 106 at its top, with a circular mounting groove at the center of the top of the protective cover 106. The top of the smoke sensor 102 passes through the protective cover 106. A threaded connecting post 109 is installed at the center of the bottom of the mounting plate 101, and the mounting plate 101 is connected to the threaded connecting hole 201 of the alarm mounting bracket 2 through the threaded connecting post 109. A battery compartment 107 is located at the bottom of the mounting plate 101 below the threaded connecting post 109, and a compartment cover 108 is installed at the top of the battery compartment 107. The protective cover 106 provides physical protection for key components such as the smoke sensor 102 and the microcontroller 103 inside. In the daily environment, it can effectively prevent dust and moisture from entering and extend the service life of the components. The battery compartment 107 provides backup power support for the alarm components, ensuring that the alarm components can continue to work in the event of a sudden power outage or main power failure, thus enhancing the reliability of the fire alarm. The compartment cover 108 facilitates battery replacement and maintenance.

[0027] When working, first select the appropriate installation method based on the characteristics and needs of the installation environment. If the wall surface is relatively smooth and flat, such as a tiled wall, the suction cup 208 at the bottom of the alarm mounting bracket 2 can be used for initial fixation. After inserting the clip 207 into the slot 209 and installing the suction cup 208, press the suction cup 208 onto the wall to make it adhere firmly. For ordinary brick walls, concrete walls, and other wall materials, when the wall surface is relatively flat, the alarm mounting bracket 2 can be fixed to the wall surface using expansion bolts or other connectors through the threaded connection hole 201. If the wall surface has a certain degree of unevenness or is obstructed by wiring pipes, the primary mounting groove 202 and primary threaded nail 204 can be used in conjunction with the tightening nut 206 to adjust the installation position, avoid obstacles, and ensure that the alarm mounting bracket 2 is installed horizontally. In some special scenarios, such as when it is necessary to install in conjunction with other equipment or when there are special requirements for the installation angle, the T-shaped insert 210 can be used to slide and adjust the position in the secondary mounting groove 203, and then fixed with the secondary threaded nail 205 to achieve diverse installation needs. After installation, After completion, the smoke sensor 102 in the alarm component continuously monitors the smoke concentration in the surrounding environment. When a fire occurs and smoke is generated, the smoke enters the circular mounting slot of the protective cover 106 and is detected by the smoke sensor 102. The smoke sensor 102 transmits the smoke concentration signal to the microcontroller 103 located above it. The microcontroller 103 quickly analyzes and processes the signal. Once the smoke concentration reaches the preset alarm threshold, it immediately activates the audible and visual buzzer 105 to emit a strong audible and visual alarm signal to alert surrounding personnel. At the same time, the microcontroller 103 controls the transmitter 104 to send out the fire alarm information, which is transmitted to the relevant monitoring center, fire department, and user-preset receiving devices such as mobile phones and computers via wireless or wired networks. Throughout the process, the battery compartment 107 at the bottom of the mounting plate 101 serves as a backup power source, continuously supplying power to the alarm component in the event of a power outage or other emergencies, ensuring that the alarm operation is not affected. The cover 108 protects the battery in the battery compartment 107, and can be easily opened for operation when the battery needs to be replaced.

[0028] Through the above steps, the threaded connection hole 201 can be connected to a wall or other fixed surface via the primary threaded nail 204 and the secondary threaded nail 205. This method is relatively simple to operate, and construction personnel only need to use common installation tools such as electric drills and screwdrivers to complete the installation process. At the same time, the primary mounting slot 202 and the secondary mounting slot 203 provide more options for installation. When space is limited or a specific angle of installation is required, the mounting slot can be used with the T-shaped insert plate 210 to flexibly adjust the installation angle and position, meeting the needs of visibility and operability of the alarm component in different scenarios. The combination of the clamping post 207 and the suction cup 208 provides a quick and temporary installation method, and the tightening nut... The engagement of nut 206 with the threaded pin enhances the stability of the installation. Even when encountering external interference such as vibration or wind, the tightening nut 206 prevents the threaded pin from loosening, ensuring that the alarm component will not fall off or shift due to insecure installation. The locking post 207 provides a stable support structure for the suction cup 208, allowing the suction cup 208 to evenly distribute the force while bearing the weight of the alarm component, thus enhancing the reliability of adsorption. Especially on smooth surfaces with high humidity or slight unevenness, the support of the locking post 207 helps the suction cup 208 to better adhere to the surface, improving the adsorption force and ensuring that the alarm component can be stably installed in the predetermined position under various environmental conditions, enabling it to perform its alarm function promptly and accurately.
