Description

Technical Field

[0001] This utility model belongs to the field of building fire alarm technology, specifically relating to an alarm device for building electrical engineering installation. Background Technology

[0002] Common alarm devices have limitations. Many only trigger an alarm when smoke concentration reaches a high level, making it difficult to accurately identify and alarm when only a small amount of smoke is produced in the early stages of a fire. This leads to missed opportunities for firefighting, and once a fire spreads, it often causes huge property damage and casualties, affecting the entire building space and surrounding areas. The key contributing factors are insufficient sensitivity of smoke sensors and unscientific alarm threshold settings. On the other hand, for the detection of gas leaks, especially liquefied petroleum gas (LPG), existing detection alarm devices either lack sufficient accuracy to detect even minor leaks in time, or have poor stability, easily resulting in false alarms or missed alarms. Once an LPG leak is not detected in time, it can easily explode upon contact with an open flame, endangering the lives and property of the entire building and surrounding residents. In addition, the installation and dismantling of existing alarm devices are generally inconvenient. In the daily maintenance of building electrical engineering, alarm devices need to be inspected, cleaned, and have parts replaced regularly. However, the installation of traditional alarm devices is complex, requiring specialized tools and a long time to complete dismantling and reinstallation. This greatly reduces maintenance efficiency and increases maintenance costs, affecting all aspects of building electrical system maintenance.

[0003] Authorized publication number "CN118678604A" describes a fire alarm device for building electrical engineering, including a housing, a labyrinth cover connected to the housing, a sealing assembly connected to the labyrinth cover, a rack connected to the labyrinth cover, a return rod fixed to the labyrinth cover, a rotating rod fixed to the labyrinth cover, and a filter screen installed on the labyrinth cover; the housing is connected to a detection alarm mechanism, a partition plate is fixed to the housing, a support plate is fixed to the partition plate, and a clamping mechanism is connected to the support plate; the clamping mechanism includes a limiting assembly, a pawl, a gear, and a ratchet; the limiting assembly includes a sleeve, a first spring, and a limiting rod. In this invention, the rack moves upward with the labyrinth cover, thereby driving the gear and ratchet to rotate clockwise. The ratchet rotation causes the pawl to rotate. Since the ratchet cannot rotate in reverse, the labyrinth cover is fixed. By pressing the labyrinth cover, it rises, causing the pawl to rotate via the rotating rod. The pawl compresses the limiting rod, causing the limiting rod to contract, thus restricting the position of the pawl.

[0004] The aforementioned patent utilizes a rack that moves upwards with the labyrinth cover, causing the gears and ratchet to rotate clockwise. The ratchet's rotation causes the pawl to rotate, and since the ratchet cannot rotate in reverse, it secures the labyrinth cover. Pressing the labyrinth cover causes it to rise, which in turn rotates the pawl via a rotating rod. The pawl then compresses a limiting rod, causing it to retract and thus restricting the pawl's position. However, this patent has certain limitations in its application. On the one hand, it cannot identify and alarm for smoke inside buildings, making it difficult to issue timely warnings in the early stages of a fire to prevent its spread. On the other hand, the patent cannot detect and alarm for liquefied petroleum gas (LPG), failing to prevent safety hazards caused by LPG leaks. Furthermore, existing alarm devices are extremely inconvenient to install and remove, resulting in very low efficiency for routine maintenance. Utility Model Content

[0005] The purpose of this invention is to provide an alarm device for building electrical engineering installation, aiming to solve two problems in existing technology. Firstly, existing devices cannot identify and alarm for smoke inside buildings, making it difficult to issue timely warnings in the early stages of a fire to prevent its spread. Secondly, they also cannot detect and alarm for liquefied petroleum gas (LPG), failing to prevent safety hazards caused by LPG leaks. Furthermore, existing alarm devices are extremely inconvenient to install and remove, resulting in very low efficiency in routine maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An alarm device for building electrical engineering installation, comprising:

[0008] A smoke detector, wherein a fixed sleeve is movably snapped onto the outer surface of the smoke detector, a liquefied gas detector is fixedly connected to the circumferential surface of the fixed sleeve, and a connecting plate is fixedly connected to the top of the liquefied gas detector;

[0009] The first positioning block is fixedly connected to the top of the smoke alarm, and limit grooves are provided at both ends of the first positioning block.

[0010] The connecting conduit is disposed within the first positioning block and the fixing sleeve; and

[0011] A connecting mechanism is provided inside a fixed sleeve, and the connecting mechanism is used to position and fix the first positioning block.

[0012] As a preferred embodiment of this utility model, the connecting mechanism includes:

[0013] The mounting slots are provided in two places, and both mounting slots are formed on the inner circumference of the fixing sleeve.

[0014] The springs are provided in two parts, and the two springs are respectively fixedly connected to the inner walls of two mounting slots that are close to each other;

[0015] The positioning holes are provided in two places, and the two positioning holes are respectively opened on the inner walls of the two mounting slots that are close to each other;

[0016] The limiting groove is provided in two places, and both limiting grooves are formed on the circumferential surface of the smoke alarm.

[0017] The second positioning block is provided in two parts. The two second positioning blocks are slidably connected in two mounting slots and two positioning holes respectively, and the two second positioning blocks are movably engaged in two limiting slots respectively.

[0018] As a preferred embodiment of this utility model, a second plastic sleeve is fixedly connected to the circumferential surface of each of the two second positioning blocks.

[0019] As a preferred embodiment of this utility model, the two second positioning blocks are in an inverted T shape.

[0020] In a preferred embodiment of this utility model, a plastic pad is fixedly connected to the top of the connecting plate, and two first plastic sleeves are fixedly connected to the circumferential surface of the fixing sleeve.

[0021] As a preferred embodiment of this utility model, an LED alarm light is installed on the circumferential surface of the fixing sleeve.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This solution is equipped with a liquefied petroleum gas (LPG) alarm, which has the ability to accurately detect LPG leaks. When the LPG concentration is detected to exceed the safe range, an alarm will be sounded immediately, effectively preventing serious safety accidents such as explosions and poisoning caused by LPG leaks. In conjunction with smoke detectors, it comprehensively improves the safety of the building's electrical environment and protects the lives and property of residents in the building and surrounding areas. This effect is due to the setting of the LPG alarm and its accurate detection function, which solves the problems of traditional LPG leak detection and alarm equipment.

[0024] The design of the connection mechanism, including the coordinated operation of components such as the mounting groove, spring, positioning hole, and second positioning block, enables convenient and reliable connection and disassembly between the smoke alarm and the fixing sleeve. During installation, align the smoke alarm with the fixing sleeve, insert the limiting groove and the second positioning block accordingly, and the spring assists in completing the installation. During disassembly, push the second positioning block to overcome the spring force to remove it. Furthermore, the inverted T-shaped design of the second positioning block, the buffering and friction-increasing effect of the second plastic sleeve, the plastic pad at the top of the connecting plate, and the design of the first plastic sleeve on the circumferential surface of the fixing sleeve all further facilitate installation and disassembly. This convenient installation and disassembly structure significantly shortens maintenance time, improves daily maintenance efficiency, reduces maintenance costs, ensures that the alarm device is always in good operating condition, and promptly provides a safety warning, solving the problem of inconvenient installation and disassembly of traditional alarm devices.

[0025] 2. In this solution, the smoke detector adopts a highly sensitive smoke detection mechanism, which can monitor the smoke concentration in the building's electrical environment in real time. Once the smoke concentration reaches the preset danger threshold, it can quickly trigger the alarm mechanism and issue an alarm signal. Compared with traditional devices, it greatly advances the alarm time, providing early warning for the prevention of electrical fires and their spread. It effectively prevents the spread of fire in its initial stage, reduces property damage and casualties caused by fire, and protects the safety of the entire building and its occupants. This effect is closely related to the installation of the smoke detector and the optimization of smoke detection and alarm functions, solving the shortcomings of traditional devices in smoke detection and alarm in the early stages of a fire.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figures 1-4 The present invention provides the following technical solution:

[0035] An alarm device for building electrical engineering installation, comprising:

[0036] A smoke alarm 1 has a fixed sleeve 2 that is movably snapped onto its outer surface. A liquefied gas alarm 4 is fixedly connected to the circumferential surface of the fixed sleeve 2. A connecting plate 5 is fixedly connected to the top of the liquefied gas alarm 4.

[0037] The first positioning block 101 is fixedly connected to the top of the smoke alarm 1, and limit grooves 102 are provided at both ends of the first positioning block 101.

[0038] Connecting conduit 9, which is disposed within the first positioning block 101 and the fixing sleeve 2; and

[0039] A connecting mechanism is provided inside the fixed sleeve 2. The connecting mechanism is used to position and fix the first positioning block 101.

[0040] In a specific embodiment of this utility model, the smoke detector 1, as one of the core components of the device, primarily functions to monitor the smoke concentration in the building's electrical environment in real time. When the smoke concentration reaches a preset danger threshold, it can quickly trigger the alarm mechanism and issue an alarm signal, providing early warning to prevent the occurrence and spread of electrical fires and ensuring the safety of life and property of people inside the building.

[0041] The fixing sleeve 2 plays a crucial role in connection and fixation. It engages with the outer surface of the smoke alarm 1, providing additional support and enhancing its installation stability. Furthermore, its circumferential surface securely connects it to the liquefied gas alarm 4, achieving integrated operation of the two alarms and enabling them to work together to ensure the safety of the building's electrical environment. Simultaneously, the fixing sleeve 2 also provides space for the connecting conduit 9, facilitating the organization and protection of the wiring.

[0042] The LPG alarm 4 is designed to detect LPG leaks within buildings. Once the LPG concentration exceeds safe limits, it will immediately sound an alarm, effectively preventing serious safety accidents such as explosions and poisoning caused by LPG leaks. Complementing the smoke alarm 1, it comprehensively enhances the safety of the building's electrical environment.

[0043] The connecting plate 5 is located at the top of the liquefied gas alarm 4 and is mainly used to connect with other equipment or structures. It can serve as an interface to facilitate the connection of the entire alarm device with the building's monitoring system, alarm linkage equipment, etc., enabling remote transmission of alarm information and system linkage control, thereby further improving the functionality and practicality of the alarm device.

[0044] The first positioning block 101 is fixed to the top of the smoke alarm 1. The limiting grooves 102 at both ends of the block cooperate with the connecting mechanism to achieve precise positioning and fixation. During installation, the interaction between the limiting grooves 102 and the connecting mechanism ensures that the connection position between the smoke alarm 1 and the fixing sleeve 2 is accurate, while also enhancing the firmness of the connection, preventing displacement or loosening during use, and ensuring the stable operation of the alarm device.

[0045] The connecting conduit 9 is housed within the first positioning block 101 and the fixing sleeve 2, responsible for housing and protecting the connecting lines of the alarm device. It effectively prevents exposed lines from being damaged, such as by external pulling, wear, or electrical interference, ensuring a stable and reliable electrical connection for the alarm device. This guarantees that the smoke alarm 1 and the liquefied gas alarm 4 can receive and transmit signals normally, thereby achieving accurate alarm functionality.

[0046] The connecting mechanism is installed inside the fixed sleeve 2, and its core function is to position and fix the first positioning block 101. By cooperating with the limiting grooves 102 at both ends of the first positioning block 101, the smoke alarm 1 is firmly fixed to the fixed sleeve 2 during installation, ensuring the stability of the entire alarm device structure and ensuring that the smoke alarm 1 and the liquefied gas alarm 4 can work normally under various environmental conditions, realizing effective monitoring and alarm of the building electrical engineering environment.

[0047] It should be noted that the specific models of smoke detector 1, liquefied gas detector 4, and LED warning light 8 used shall be selected by those skilled in the art. Furthermore, the smoke detector 1, liquefied gas detector 4, and LED warning light 8 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0048] Please refer to the details. Figures 1-4 The connecting mechanism includes:

[0049] Mounting slot 3, there are two mounting slots 3, both of which are opened on the inner circumference of the fixing sleeve 2;

[0050] Spring 12, two springs 12 are provided, and the two springs 12 are respectively fixedly connected to the inner walls of the two mounting slots 3 close to each other;

[0051] Positioning holes are provided, and the two positioning holes are respectively opened on the inner walls of the two mounting slots 3 that are close to each other;

[0052] There are two limiting grooves 102, and both limiting grooves 102 are formed on the circumferential surface of the smoke alarm 1.

[0053] The second positioning block 11 is provided in two parts. The two second positioning blocks 11 are slidably connected to the two mounting grooves 3 and the two positioning holes respectively, and the two second positioning blocks 11 are movably engaged in the two limiting grooves 102 respectively.

[0054] In this embodiment: When it is necessary to install the smoke alarm 1 onto the fixing sleeve 2, first align the smoke alarm 1 with the fixing sleeve 2, so that the limiting groove 102 on the circumferential surface of the smoke alarm 1 corresponds to the second positioning block 11 in the mounting groove 3 on the inner circumferential wall of the fixing sleeve 2. During the insertion process, the smoke alarm 1 presses against the second positioning block 11, causing the second positioning block 11 to slide into the mounting groove 3 against the elastic force of the spring 12, while the spring 12 is compressed. When the limiting groove 102 moves to the position aligned with the second positioning block 11, the spring 12 restores its elastic deformation, pushing the second positioning block 11 to quickly snap into the limiting groove 102. At this time, the smoke alarm 1 is firmly fixed on the fixing sleeve 2.

[0055] When it is necessary to disassemble the smoke alarm 1, apply external force to push the second positioning block 11, causing it to overcome the elastic force of the spring 12 and slide into the mounting groove 3, disengaging from the limiting groove 102. At this time, the smoke alarm 1 can be removed from the fixing sleeve 2, completing the disassembly operation. The entire connection mechanism, through the elastic force of the spring 12 and the mutual cooperation between the various components, realizes the convenient and reliable connection and disassembly function between the smoke alarm 1 and the fixing sleeve 2.

[0056] Please refer to the details. Figures 1-3The two second positioning blocks 11 are fixedly connected to the circumferential surfaces of the second plastic sleeves 10.

[0057] In this embodiment, the second plastic sleeve 10 serves to buffer and increase friction. When the second positioning block 11 is engaged in the limiting groove 102, the second plastic sleeve 10 contacts the inner wall of the limiting groove 102. This prevents the second positioning block 11 from being damaged due to direct friction with the limiting groove 102, thus extending the service life of the component.

[0058] Please refer to the details. Figure 2 The two second positioning blocks 11 are in an inverted T shape.

[0059] In this embodiment, the inverted T-shaped design makes the second positioning block 11 more stable when sliding in the mounting groove 3, and less prone to tilting or displacement. The horizontal part of the T-shape can act as a limit in the mounting groove 3 to prevent the second positioning block 11 from coming out of the mounting groove 3, while its vertical part can be accurately inserted into the limiting groove 102 to ensure the accuracy and reliability of the connection.

[0060] Please refer to the details. Figures 1-4 A plastic pad 7 is fixedly connected to the top of the connecting plate 5, and two first plastic sleeves 6 are fixedly connected to the circumferential surface of the fixing sleeve 2.

[0061] In this embodiment, the plastic pad 7 serves as a buffer and anti-slip material. When the entire alarm device is connected to other equipment or structures via the connecting plate 5, the plastic pad 7 prevents hard contact between the connecting plate 5 and the connected object, thus preventing damage caused by collision during the connection process. The fixing sleeve 2 not only connects the smoke alarm 1 and the liquefied gas alarm 4, but also has two first plastic sleeves 6 fixedly connected to its circumferential surface.

[0062] Please refer to the details. Figures 1-3 LED alarm lights 8 are installed on the circumferential surface of the fixed sleeve 2.

[0063] In this embodiment, the LED alarm light 8 serves as a visual warning component of the alarm device, linked with the smoke alarm 1 and the liquefied gas alarm 4. When the smoke alarm 1 detects excessive smoke concentration or the liquefied gas alarm 4 detects a liquefied gas leak, the LED alarm light 8 will illuminate, emitting a conspicuous light signal to visually warn surrounding personnel of a potential safety hazard. Working in conjunction with other alarm components such as the audible and visual alarms, it comprehensively enhances the alarm effect.

[0064] The working principle and usage process of this utility model are as follows: When installing the device, first fix the fixing sleeve 2 in a suitable position inside the building, pick up the smoke alarm 1, and align the limiting groove 102 on its circumferential surface with the second positioning block 11 in the mounting groove 3 on the inner circumference of the fixing sleeve 2. During the insertion process, the second positioning block 11 is squeezed to overcome the elastic force of the spring 12 and slides into the mounting groove 3. The spring 12 is compressed. When the limiting groove 102 is aligned with the second positioning block 11, the spring 12 returns to its deformation and pushes the second positioning block 11 into the limiting groove 102, thus completing the installation of the smoke alarm 1 and the fixing sleeve 2. Since the fixing sleeve 2 has been pre-connected to the liquefied gas alarm 4, and the connecting plate 5 at the top of the liquefied gas alarm 4 can be used to connect external equipment, if a connection is required, it can be connected through the connecting plate 5. The plastic pad 7 at the top can avoid hard contact and ensure a stable connection. During use, the smoke alarm 1 continuously monitors the smoke concentration. Once the preset danger threshold is reached, the alarm mechanism is immediately triggered, emitting an alarm signal and driving its own alarm component to illuminate the LED alarm light 8 via the connecting pipe 9. The liquefied gas alarm 4 monitors the liquefied gas concentration in real time. When the concentration exceeds the safe range, it also immediately emits an alarm signal, illuminating the LED alarm light 8 via the connecting pipe 9 to promptly warn personnel. When maintenance is required, first remove any external equipment connected to the connecting plate 5, then apply external force to push the second positioning block 11 to overcome the elastic force of the spring 12 and disengage from the limiting groove 102. The smoke alarm 1 can then be removed for individual maintenance. The first plastic sleeve 6 on the circumferential surface of the fixing sleeve 2 increases the hand grip friction, facilitating disassembly.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
