Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to an automatic fault alarm device for fire protection equipment. Background Technology

[0002] In the field of fire safety, smoke detectors, as a key automatic fault alarm device, are widely used in various buildings to monitor the concentration of smoke in the air in real time, so as to issue an alarm in the early stage of a fire and buy valuable time for personnel evacuation and fire fighting and rescue.

[0003] A search revealed Chinese patent CN219085497U, which discloses a fire smoke alarm that is easy to clean. The alarm body has a connecting ring fixed to its lower end. The inner wall of the connecting ring has a slot, and a protective net is connected inside the connecting ring. A locking block matching the slot is fixed to the side wall of the protective net, and a tube is fixed to the lower end of the protective net. The slot is L-shaped. This novel fire smoke alarm, designed for easy cleaning, utilizes a connecting ring with a slot, and a locking block fixed to the outer wall of the protective net. The locking block matches the slot, securing the protective net within the connecting ring at the lower end of the alarm body. This allows for convenient cleaning of the protective net and rotation of the brush during alarm body inspection and maintenance.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing automatic alarm systems for fire protection equipment present numerous installation problems. Taking the common connection method between smoke detectors and their bases as an example, most employ complex fixing structures, such as simple screw tightening. This requires operators to use specialized tools and spend considerable time aligning the screw holes and repeatedly tightening the screws during installation or removal. The process is cumbersome, inefficient, and fails to meet the needs of rapid installation and maintenance, especially in large-scale installations or emergency repairs. Furthermore, existing base-to-wall fixing methods are often not stable enough, using only a few fixing points or simple adhesive methods. This makes smoke detectors prone to loosening and displacement due to vibration, impact, and other external forces during long-term use. This not only affects their normal monitoring function but may also lead to false alarms or missed alarms, posing a significant fire safety hazard. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes an automatic fault alarm device for fire protection equipment. The design completely eliminates the traditional and complex screw fastening method. No professional tools are required, and technicians can easily assemble and disassemble the smoke alarm body and base body by hand, greatly shortening installation and maintenance time and effectively improving work efficiency.

[0007] The technical solution to achieve the purpose of this utility model is: an automatic fault alarm device for fire-fighting equipment, including a smoke alarm body and a base body, wherein a detection port is opened on the outer side of the smoke alarm body, and an alarm light for alarm is provided at the bottom of the smoke alarm body, and further includes;

[0008] The docking mechanism is respectively set on the upper and lower sides of the adjacent ends of the smoke alarm body and the base body, and the forward and reverse rotation can control the smoke alarm body to be detachably connected to the bottom of the base body.

[0009] The docking mechanism includes a concave block on the connecting base body and a connecting foot on an adjacent concave block on the smoke alarm body. The connecting foot has an L-shaped structure and is inserted into the concave block from the opening. One end of the connecting foot inserted into the concave block is provided with an elastic limiting protrusion. A limiting hole communicating with the inside of the concave block is opened on the side of the concave block near the smoke alarm body. The limiting protrusion extends outward from the limiting hole inside the concave block.

[0010] A fixing component is provided at the center of the base body near the end of the smoke alarm body.

[0011] In some embodiments, the base body has a fixing groove on the side near the smoke alarm body, and the fixing component includes a connecting pipe that connects to the bottom surface inside the fixing groove, and a fixing bolt that passes through the other side of the base body is threaded onto the connecting pipe, so that the base body is threadedly fixed to the wall by the fixing bolt.

[0012] In some embodiments, at least four sets of fixing components are provided inside the fixing groove between the smoke alarm body and the base body.

[0013] In some embodiments, the connecting feet and the limiting protrusions are both made of elastic insulating material.

[0014] In some embodiments, a cover is provided at the opening of the fixing groove, and the opening is sealed by the cover snapping onto the fixing groove.

[0015] In some embodiments, a protective ring is fitted around the outer side of the smoke detector body, and the outer surface of the protective ring is provided with anti-slip texture.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this utility model is equipped with a docking mechanism. By connecting the concave block on the base body and the L-shaped connecting foot on the smoke alarm body, the connecting foot is inserted from the opening of the concave block, and the elastic limiting protrusion at the insertion end can extend from the limiting hole of the concave block, so as to realize the detachable connection of the smoke alarm body to the bottom of the base body. The installation and disassembly can be controlled by rotating in both directions, which is convenient to operate and solves the problems of complex connection method between the existing smoke alarm and the base and inconvenient installation and disassembly.

[0018] Secondly, this utility model has a fixing component set at the center of the base body near the smoke alarm body. A fixing groove is opened on the side of the base body near the smoke alarm body. A connecting pipe is connected to the bottom surface of the groove. A fixing bolt that passes through the other side of the base body is threaded on the connecting pipe. At least four sets of fixing components are set, which can securely fix the base body to the wall with threads, greatly enhancing the installation stability of the entire alarm device on the wall and solving the problem that existing automatic fault alarm devices for fire protection equipment are not securely installed on the wall and are easy to shake.

[0019] Thirdly, this utility model has a protective ring fitted on the outside of the smoke alarm body. The outer surface of the protective ring has anti-slip texture. When the smoke alarm body is connected to the base body, on the one hand, the protective ring can increase the friction of the smoke alarm body in the palm of the technician's hand, so as to play an anti-slip role. On the other hand, it is easier to rotate the protective ring to drive the docking component between the smoke alarm body and the base body, thus improving the installation efficiency and solving the problem that existing smoke alarms are not easy to hold and are difficult to operate during installation.

[0020] Fourthly, this utility model has a cover at the opening of the fixing groove. The cover is snapped onto the fixing groove to seal the opening. This not only prevents water leakage from the wall from dripping onto the smoke alarm body through the limiting hole, but also covers and hides the fixing bolt inside the fixing groove, thus providing protection, extending the service life of the equipment, and solving the problems of existing fire equipment automatic fault alarm devices being easily soaked in water and the fixing parts being easily damaged.

[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0031] This utility model provides an automatic fault alarm device for fire-fighting equipment through improvements. The technical solution of this utility model is as follows:

[0032] Example 1, as Figure 1 - Figure 2As shown, an automatic fault alarm device for fire protection equipment includes a smoke alarm body 1 and a base body 2. The smoke alarm body 1 has a detection port 101 on its outer side, and an alarm light 102 for alarm purposes is provided at the bottom of the smoke alarm body 1. It also includes a docking mechanism and a fixing component. The docking mechanism is respectively provided on the upper and lower sides of the adjacent ends of the smoke alarm body 1 and the base body 2, and can be rotated in both directions to control the detachable connection of the smoke alarm body 1 to the bottom of the base body 2. The docking component detachably connects the smoke alarm body 1 and the base body 2 for easy assembly. Specifically, the docking mechanism includes a concave block 3 on the base body 2 and a connecting foot 301 on the adjacent concave block 3 on the smoke alarm body 1. The connecting foot 301 has an L-shaped structure and is inserted into the concave block 3 from the opening. One end of the connecting foot 301 inserted into the concave block 3 is provided with an elastic limiting protrusion 3012. Both the connecting foot 301 and the limiting protrusion 3012 are made of elastic insulating material. When the base body 2 and the smoke alarm body 1 are connected by the concave block 3, the connecting foot 301, and the limiting protrusion 3012 in the fixing assembly, electrical conduction is prevented. The side of the concave block 3 near the smoke alarm body 1 has a limiting hole 303 that communicates with the interior of the concave block 3. The limiting protrusion 3012 extends outward from the limiting hole 303 inside the concave block 3. The fixing assembly is located at the center of the end of the base body 2 near the smoke alarm body 1.

[0033] A protective ring 5 is fitted onto the outer side of the smoke alarm body 1, and the outer surface of the protective ring 5 is provided with anti-slip texture. By providing a protective ring 5 with anti-slip texture on the outer surface of the smoke alarm body 1, when the smoke alarm body 1 is docked with the base body 2, the protective ring 5 can increase the friction of the smoke alarm body 1 in the palm of the technician's hand, thus achieving an anti-slip effect. At the same time, rotating the protective ring 5 to drive the docking component between the smoke alarm body 1 and the base body 2 can reduce the effort required.

[0034] like Figure 3 As shown, in Embodiment 2, based on Embodiment 1 above, the base body 2 has a fixing groove 201 on the side near the smoke alarm body 1. The fixing component includes a connecting pipe 202 that connects to the bottom surface inside the fixing groove 201, and a fixing bolt 203 that passes through the other side of the base body 2 is threaded onto the connecting pipe 202. The base body 2 is threadedly fixed to the wall by the fixing bolt 203. At least four sets of fixing components between the smoke alarm body 1 and the base body 2 are provided inside the fixing groove 201 to enhance the fixing effect between the base body 2 and the wall.

[0035] like Figure 4 - Figure 6As shown, in Embodiment 3, based on Embodiments 1 and 2, to prevent water leakage from the wall from dripping onto the smoke alarm body 1 through the limiting hole 303, a cover 204 is attached to the opening of the fixing groove 201 to block the opening. The cover 204 seals the opening of the fixing groove 201. The cover 204 is elastic, allowing it to be easily engaged inside the fixing groove 201, sealing the opening. However, this prevents water leakage from the wall behind the base body 2 from seeping into the back of the smoke alarm body 1 through the gap between the connecting pipe 202 and the fixing bolt 203. Simultaneously, it also conceals the fixing bolt 203 inside the fixing groove 201.

[0036] Working principle and usage process of this utility model:

[0037] Working principle:

[0038] The smoke alarm body 1 is connected to the base body 2 via a docking mechanism. The concave block 3 in the docking mechanism is fixed to the base body 2. The connecting foot 301 at the bottom of the smoke alarm body 1 has an L-shaped structure, utilizing its own elasticity to insert into the interior through the opening of the concave block 3 (e.g., ...). Figure 1 , Figure 2 and Figure 6 (As shown). After insertion, the connecting pin 301 inserts into the elastic limiting protrusion 3012 at one end of the concave block 3, and extends outward from the limiting hole 303 that connects to the inside of the concave block 3 on the side of the concave block 3 near the smoke alarm body 1, thereby locking the concave block 3 and achieving a stable connection between the smoke alarm body 1 and the base body 2. In addition, the insulating material of the connecting pin 301 and the limiting protrusion 3012 prevents electrical conduction and ensures electrical safety.

[0039] Regarding the fixing components, a connecting pipe 202 is connected to the bottom surface of the fixing groove 201 opened on the side of the base body 2 near the smoke alarm body 1. A fixing bolt 203 that passes through the other side of the base body 2 is threaded onto the connecting pipe 202. By screwing the fixing bolt 203 into the wall, the base body 2 is firmly fixed to the wall using at least four such fixing components.

[0040] Usage process:

[0041] During installation, first, install the base body 2 in the predetermined position on the wall using the fixing components. Specifically, pass the fixing bolt 203 through the connecting pipe 202 and screw it into the wall. Generally, use a screwdriver or similar tool to tighten it, ensuring the base body 2 is stable. If there are multiple fixing components, complete the fixing sequentially. Next, pick up the smoke alarm body 1 and align its bottom connecting foot 301 with the opening of the concave block 3 on the base body 2. Press down slightly and rotate. During insertion into the concave block 3, the elastic limiting protrusion 3012 is compressed and retracts. After full insertion, the limiting protrusion 3012 pops out from the limiting hole 303, completing the connection between the smoke alarm body 1 and the base body 2. To disassemble the smoke alarm body 1, simply rotate it in the opposite direction and gently pull it out. In daily use, the detection port 101 around the outer edge of the smoke alarm body 1 monitors the smoke concentration in the surrounding environment in real time. Once the smoke concentration reaches the set threshold, the alarm light 102 at the bottom will illuminate, alerting nearby personnel. If the smoke detector body 1 is found to be faulty and requires repair or replacement, it can be easily disassembled via the docking mechanism for operation. After repair, it can be reinstalled according to the above installation procedure. Meanwhile, during installation, the protective ring 5, with its anti-slip texture, is easy for technicians to grip. Rotating the protective ring 5 assists in the docking operation between the connecting foot 301 and the concave block 3, saving effort and increasing efficiency. The cover 204 at the opening of the fixing groove 201 always serves to waterproof and protect the fixing bolt 203, preventing water immersion and other factors from affecting the normal operation of the equipment.

[0042] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
