Description

Technical Field

[0001] This utility model relates to the field of fire alarm technology, specifically a protective component for a BIM-based intelligent fire alarm during the operation and maintenance phase. Background Technology

[0002] A fire alarm is the sensing component of an automatic fire alarm system. It responds to fire parameters and automatically generates a fire alarm signal. With the gradual maturation of BIM technology, when a fire alarm is in operation, workers can see the specific floor and room where the fire is occurring through a display screen, thereby achieving the goal of rapid fire suppression. Consequently, the accuracy requirements for the internal sensors of the fire alarm are high, leading to the installation of protective components on its exterior.

[0003] In the prior art, the protective component is generally a filter screen. By installing the filter screen on the mounting frame and fixing it with bolts, the filter screen is installed relatively stably, which prevents dust from adhering to the sensor and thus prevents dust from reducing the accuracy of the sensor.

[0004] However, after prolonged use, dust will accumulate on the surface of the filter, affecting the accuracy of the sensor. This necessitates disassembling and cleaning the filter, requiring workers to use ladders and tools such as screwdrivers to remove the bolts. This makes disassembly and cleaning the filter inconvenient, affecting not only the cleaning efficiency but also increasing the operational risks for workers. Utility Model Content

[0005] The purpose of this invention is to provide a protective component for a BIM-based intelligent fire alarm during the operation and maintenance phase, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective component for a BIM-based intelligent fire alarm during the operation and maintenance phase, comprising a body, a mounting frame fixedly connected to the lower side of the body, a placement ring sleeved on the outside of the mounting frame, and multiple filters detachably connected inside the placement ring.

[0007] Preferably, one end of the placement ring is fixedly connected to a connecting piece one, and the other end of the placement ring is fixedly connected to a connecting piece two. A slot is provided inside the right side of the connecting piece one, and a plug is fixedly connected to the left side of the slot. The plug is engaged inside the slot.

[0008] Preferably, the filter screen has slots on both the upper and lower sides, and the placement ring has mounting slots on both the upper and lower sides. A push rod is slidably connected inside the mounting slot, and an elastic element is sleeved on the outside of the push rod. One end of the push rod is fixedly connected to an arc block, and the other end of the push rod is fixedly connected to a push plate. The end of the push plate away from the push rod is fixedly connected to a locking block.

[0009] Preferably, the right side of the first connecting piece fits into the left side of the second connecting piece, and the outer surface of the insert is tapered and adapted to the interior of the slot.

[0010] Preferably, the outer side of the first connecting piece is slidably connected to the inner side of the mounting frame, and the outer side of the second connecting piece is slidably connected to the inner side of the mounting frame.

[0011] Preferably, the push plate is slidably connected inside the mounting groove, the arc block is slidably connected inside the mounting groove, and the side of the arc block away from the push rod is slidably connected to the inner wall of the mounting frame.

[0012] Preferably, one end of the elastic element is fixedly connected to the inner wall of the mounting groove, the other end of the elastic element is fixedly connected to the push plate, one side of the locking block is slidably connected to the inside of the mounting groove, and the other side of the locking block is engaged with the inside of the locking groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The protective component for intelligent fire alarms based on BIM during the operation and maintenance phase proposed in this utility model involves installing a filter screen inside an installation ring, and then fitting the installation ring inside an installation frame. This makes the installation, disassembly, and cleaning of the filter screen more convenient, eliminating the need for workers to carry tools and climb ladders. This not only improves cleaning efficiency but also enhances worker safety. Furthermore, it allows for the cleaning of individual filter screens, thereby reducing the labor intensity of workers.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a protective component for a BIM-based intelligent fire alarm during the operation and maintenance phase, including a body 1, a mounting frame 2 fixedly connected to the lower side of the body 1, a sensor installed inside the mounting frame 2, a placement ring 3 sleeved on the outside of the mounting frame 2, and multiple filters 4 detachably connected inside the placement ring 3. The placement ring 3 provides installation space for the filters 4, making it easy to install the filters 4, and the filters 4 are used to protect the sensors inside the mounting frame 2, so that dust will not adhere to the sensors inside the mounting frame 2.

[0025] When the filter screen 4 needs to be cleaned, pulling one side of the placement ring 3 allows the placement ring 3 to detach from the mounting frame 2, thus enabling the entire filter screen 4 to be cleaned. Furthermore, pulling the filter screen 4 outwards allows it to slide out from inside the placement ring 3, enabling the cleaning of a single filter screen 4. Conversely, it can be easily installed. This makes the installation, disassembly, and cleaning of the filter screen 4 convenient, eliminating the need for workers to carry tools or climb ladders. This not only increases cleaning efficiency but also improves worker safety and reduces labor intensity.

[0026] Example 2: Based on Example 1, in order to achieve a more stable installation of the placement ring 3, a connecting piece 5 is fixedly connected to one end of the placement ring 3. The outside of the connecting piece 5 is slidably connected to the inside of the mounting frame 2. The mounting frame 2 limits the connecting piece 5, allowing it to slide stably. A connecting piece 6 is fixedly connected to the other end of the placement ring 3. The outside of the connecting piece 6 is slidably connected to the inside of the mounting frame 2. The mounting frame 2 limits the connecting piece 6, preventing it from shifting during sliding. The right side of the connecting piece 5 fits against the left side of the connecting piece 6, thus making the installation of the connecting piece 5 and the connecting piece 6 more stable. A slot 7 is provided inside the right side of the connecting piece 5. A plug 8 is fixedly connected to the left side of the slot 7. The outside of the plug 8 is a conical design and is adapted to the inside of the slot 7, allowing the plug 8 to slide easily into the inside of the slot 7. The plug 8 is engaged inside the slot 7, making the engagement between the plug 8 and the slot 7 more stable, thereby making the installation of the placement ring 3 more stable.

[0027] When disassembling the placement ring 3, by pulling the connecting piece 2 6 outward, the connecting piece 2 6 can drive the insert 8 to move outward, allowing the conical surface of the insert 8 to slide inside the slot 7, thus allowing the insert 8 to easily detach from the slot 7, and thus allowing the placement ring 3 to be easily removed from the mounting frame 2. Conversely, by fitting the placement ring 3 onto the mounting frame 2, the insert 8 is slid into the slot 7, and the insert 8 is deformed by the slot 7. When the connecting piece 1 5 and the connecting piece 2 6 are in contact, the insert 8 can perform a reset movement, thus allowing the insert 8 to engage with the slot 7, thereby making the placement ring 3 more stably installed.

[0028] Example 3: Based on Example 2, in order to achieve automatic snap-fit ​​of the filter screen 4, slots 9 are provided inside the upper and lower sides of the filter screen 4, and mounting slots 10 are provided inside the upper and lower sides of the placement ring 3. A push rod 11 is slidably connected inside the mounting slot 10, and the mounting slot 10 limits the push rod 11 so that the push rod 11 will not deviate when sliding. An elastic element 14 is sleeved on the outside of the push rod 11, and an arc block 12 is fixedly connected to one end of the push rod 11. The arc block 12 is slidably connected inside the mounting slot 10, and the mounting slot 10 limits the arc block 12 so that the arc block 12 can slide smoothly. The side of the arc block 12 away from the push rod 11 is flush with the inner wall of the mounting frame 2. The sliding connection allows the mounting frame 2 to push the arc block 12 inward. The other end of the push rod 11 is fixedly connected to the push plate 13, which is slidably connected inside the mounting groove 10. The mounting groove 10 limits the push plate 13, making the push plate 13 slide more stably. One end of the elastic element 14 is fixedly connected to the inner wall of the mounting groove 10, and the other end of the elastic element 14 is fixedly connected to the push plate 13. The end of the push plate 13 away from the push rod 11 is fixedly connected to the locking block 15. One side of the locking block 15 is slidably connected inside the mounting groove 10, so that the locking block 15 will not deviate when sliding. The other side of the locking block 15 engages with the inside of the locking groove 9, thereby making the filter screen 4 installed more stably.

[0029] When the filter screen 4 needs to be disassembled, by pulling the filter screen 4 outward, the placement ring 3 is deformed, which prevents the placement ring 3 from pressing the arc block 12, allowing the elastic element 14 to return to its original position. This allows the elastic element 14 to pull the push plate 13 outward, which in turn pulls the locking block 15 out of the slot 9, thus freeing the filter screen 4 from restriction and making it easy to disassemble. Conversely, by sliding the filter screen 4 into the placement ring 3, the arc surface of the arc block 12 slides on the inner wall of the mounting frame 2, which pushes the arc block 12 inward. This pushes the push plate 13 inward, causing the push plate 13 to deform while pulling the elastic element 14, and simultaneously engaging the locking block 15 with the inside of the slot 9, thus making the filter screen 4 more stably installed.

[0030] In actual use, when the filter screen 4 needs to be cleaned, the connecting piece 2 6 is pulled outward, which in turn causes the insert block 8 to move outward. This allows the conical surface of the insert block 8 to slide inside the slot 7, making it easy for the insert block 8 to disengage from the slot 7. This also allows the placement ring 3 to be easily removed from the mounting frame 2. When the filter screen 4 needs to be disassembled, pulling the filter screen 4 outward causes the placement ring 3 to deform, preventing it from pressing against the arc block 12. This allows the elastic element 14 to reset, pulling the push piece 13 outward. The push piece 13 then pulls the locking block 15 out of the slot 9, freeing the filter screen 4 from restriction and allowing for easy disassembly. This makes cleaning the filter screen 4 more convenient and reduces the workload for workers. The placement ring 3 is inserted into the interior of the mounting frame 2, allowing the arc surface of the arc block 12 to slide against the inner wall of the mounting frame 2. This allows the mounting frame 2 to push the arc block 12 inward, which in turn pushes the push plate 13 inward. As the push plate 13 pulls the elastic element 14 and deforms, it pushes the locking block 15 to engage with the inside of the locking groove 9, thus making the filter screen 4 more stably installed. The placement ring 3 is then placed on the mounting frame 2, allowing the insert block 8 to slide into the slot 7. The insert block 8 is then squeezed and deformed by the slot 7. When the connecting piece 1 5 and the connecting piece 2 6 are in contact, the insert block 8 can perform a reset movement, thus engaging with the slot 7. This makes the placement ring 3 more stably installed, making the installation, disassembly, and cleaning of the filter screen 4 more convenient. This eliminates the need for workers to carry tools and climb ladders, resulting in higher cleaning efficiency and greater worker safety.
