Description

Technical Field

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

[0002] Currently, traditional fire smoke monitoring equipment mostly uses point detectors, which are usually installed independently in a specific monitoring area. Each detector can only passively sense smoke within a limited range around it, thus limiting the monitoring range.

[0003] In addition, passive sensing relies on the natural diffusion of smoke to the detector, which results in a response delay. It is not sensitive enough for fire early warning in the early stages of smoke generation or in complex airflow environments, which can easily lead to false alarms or missed alarms, making it difficult to meet the safety requirements of modern buildings for accurate early warning of fires.

[0004] To address the aforementioned issues, this patent proposes a smoke monitoring solution that can expand the monitoring coverage area, improve response sensitivity, and enhance anti-interference capabilities. Utility Model Content

[0005] The main purpose of this invention is to propose a fire smoke monitoring device, which aims to solve the problems of small monitoring range and low sensitivity of traditional fire smoke monitoring devices.

[0006] To address the aforementioned problems, this utility model proposes a fire smoke monitoring device, comprising a main suction cylinder, a smoke monitor installed inside the main suction cylinder with a gap between the main suction cylinder and the smoke monitor, multiple connecting rods connected to the outer side of the upper end of the main suction cylinder, a main fixing ring connected to the upper end of the multiple connecting rods, a fan frame installed inside the upper end of the main suction cylinder, a suction fan installed inside the center of the lower end of the fan frame, and the suction fan located above the smoke monitor, multiple side suction pipes connected to the outer side of the lower end of the main suction cylinder, a connecting pipe connected to the end of each of the multiple side suction pipes away from the main suction cylinder, and a secondary suction cylinder connected to the end of each of the multiple connecting pipes away from the side suction pipes.

[0007] Preferably, the upper end of the main suction cylinder is provided with multiple positioning grooves, and the multiple positioning grooves are connected to the inside of the main suction cylinder, and the upper outer side of the smoke monitor is connected with multiple positioning ears.

[0008] Preferably, the plurality of positioning ears are respectively engaged inside the plurality of positioning slots, and the lower outer side of the fan frame is connected to the plurality of positioning posts.

[0009] Preferably, the plurality of positioning posts are respectively engaged inside the plurality of positioning slots, and the plurality of positioning posts are respectively located at the upper ends of the plurality of positioning ears.

[0010] Preferably, the positioning ear and the positioning post are fixedly connected to the main suction cylinder by bolts, and a main cylinder filter screen is provided at the lower opening of the main suction cylinder.

[0011] Preferably, both the side suction tube and the auxiliary suction cylinder are connected to a connecting head near the end of the connecting tube, and the connecting tube is connected to the side suction tube and the auxiliary suction cylinder through the two connecting heads.

[0012] Preferably, a secondary fixing ring is connected to the outer side of the upper end of the secondary suction cylinder, and a secondary cylinder filter screen is provided at the lower end opening of the secondary suction cylinder.

[0013] Beneficial effects:

[0014] 1. This utility model connects a main suction cylinder to multiple auxiliary suction cylinders connected via side suction pipes and connecting pipes, thus constructing a centralized monitoring network. Utilizing the negative pressure generated by a suction fan located inside the main suction cylinder, air samples from multiple dispersed auxiliary monitoring areas can be actively extracted into the main suction cylinder simultaneously. These samples are then uniformly analyzed by a smoke monitor inside the main suction cylinder, thereby expanding the monitoring coverage of a single device and achieving efficient and comprehensive smoke monitoring of large areas or multi-zone areas. Furthermore, the active air intake monitoring provides higher sensitivity.

[0015] 2. This utility model has multiple positioning slots on the upper end of the main suction cylinder, so that the positioning ears of the smoke monitor and the positioning posts of the fan bracket can be inserted in sequence and finally tightened uniformly by bolts. This achieves quick and accurate centering installation of the smoke monitor and the suction fan, ensuring that the smoke monitor is placed in the center of the cylinder to form a uniform annular detection airway. At the same time, it ensures that the suction fan is located directly above the smoke monitor, so that the airflow passes through stably and evenly. This not only ensures the balance of suction force on each branch, but also avoids smoke accumulation caused by uneven airflow and prevents false detection.

[0016] 3. This utility model has a main cylinder filter and a secondary cylinder filter at the lower opening of the main suction cylinder and each secondary suction cylinder, respectively. This allows the air to be drawn in from each monitoring area while impurities in the air are filtered at the front end, preventing impurities from entering the pipes, suction fans and smoke monitors. This avoids equipment blockage, wear or performance degradation caused by these factors, and improves the reliability and service life of the entire system.

[0017] 4. Both the side suction pipe and the auxiliary suction cylinder of this utility model are connected to the connecting pipe through a connecting head. The use of standardized quick connectors makes the pipeline expansion, connection and deployment of the entire monitoring network simple and flexible, greatly reducing the complexity and time of on-site installation. It is convenient to quickly add or remove monitoring nodes according to actual monitoring needs, and improves the adaptability of the system and the efficiency of engineering installation.

[0026] 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.

[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a fire smoke monitoring device, including a main suction cylinder 1. A smoke monitor 2 is installed inside the main suction cylinder 1, with a gap between the main suction cylinder 1 and the smoke monitor 2. Multiple connecting rods 3 are connected to the outer side of the upper end of the main suction cylinder 1, and a main fixing ring 4 is connected to the upper end of the multiple connecting rods 3. A fan frame 5 is installed inside the upper end of the main suction cylinder 1, and a suction fan 6 is installed inside the center of the lower end of the fan frame 5, with the suction fan 6 located above the smoke monitor 2. Multiple side suction pipes 7 are connected to the outer side of the lower end of the main suction cylinder 1. The ends of the multiple side suction pipes 7 away from the main suction cylinder 1 are all connected to a connecting pipe 8, and the ends of the multiple connecting pipes 8 away from the side suction pipes 7 are all connected to auxiliary suction cylinders 9. During the installation of the smoke monitoring device, the main suction cylinder 1 and the smoke monitor 2 are installed in the main monitoring area by the main fixing ring 4 and screws, and the multiple auxiliary suction cylinders 9 are connected to the lower part of the main suction cylinder 1 by the side suction pipes 7 and the connecting pipes 8. Outside the main monitoring unit, multiple auxiliary suction cylinders 9 are installed in multiple auxiliary monitoring areas. Then, the smoke monitor 2 and the suction fan 6 are powered on. At this time, the suction fan 6 starts and sucks the air inside the main suction cylinder 1. The suction fan 6 then discharges the sucked air through the gap between the upper opening of the main suction cylinder 1 and the main fixing ring 4. This allows the main suction cylinder 1 to actively suck in the air from the main monitoring area and multiple auxiliary monitoring areas through the lower opening and the multiple auxiliary suction cylinders 9. The air then flows through the gap between the main suction cylinder 1 and the smoke monitor 2 to the upper opening of the main suction cylinder 1. During this process, the air flowing between the main suction cylinder 1 and the smoke monitor 2 can enter the smoke monitor 2 and be detected by the smoke monitor 2. This allows for simultaneous monitoring of the air in the main monitoring area and multiple auxiliary monitoring areas, increasing the monitoring area of ​​the smoke monitoring equipment. Furthermore, the active sucking in of the air from the main monitoring area and multiple auxiliary monitoring areas effectively improves the detection sensitivity.

[0028] Preferably, the upper end of the main suction cylinder 1 has multiple positioning slots 10, which are connected to the interior of the main suction cylinder 1. The upper outer side of the smoke monitor 2 is connected to multiple positioning ears 11, which are respectively engaged within the multiple positioning slots 10. The lower outer side of the fan bracket 5 is connected to multiple positioning posts 12, which are respectively engaged within the multiple positioning slots 10. The multiple positioning posts 12 are located above the multiple positioning ears 11. The positioning ears 11 and positioning posts 12 are fixedly connected to the main suction cylinder 1 by bolts. During the installation of the main suction cylinder 1, the smoke monitor 2 can pass through the multiple positioning slots... The engagement between the 10 and multiple positioning ears 11 positions the main suction cylinder 1, allowing the smoke monitor 2 to be located inside the main suction cylinder 1 with a uniform gap between it and the main suction cylinder 1. At the same time, the fan bracket 5 and the suction fan 6 can be positioned by the engagement between multiple positioning slots 10 and multiple positioning posts 12, and the positioning ears 11 and positioning posts 12 are fixed by bolts, so that the suction fan 6 is located directly above the smoke monitor 2. This ensures that the air being sucked can pass evenly through the gap between the main suction cylinder 1 and the smoke monitor 2, which can ensure that the suction force of multiple auxiliary suction cylinders 9 is uniform and avoid smoke accumulation that could lead to misjudgment.

[0029] Preferably, a main cylinder filter 13 is provided at the lower opening of the main suction cylinder 1. The side suction pipe 7 and the auxiliary suction cylinder 9 are both connected to a connecting head 14 near the connecting pipe 8. The connecting pipe 8 is connected to the side suction pipe 7 and the auxiliary suction cylinder 9 through two connecting heads 14. A secondary fixing ring 15 is connected to the outer side of the upper end of the auxiliary suction cylinder 9. A secondary cylinder filter 16 is provided at the lower opening of the auxiliary suction cylinder 9. During the process of suctioning air into the main monitoring area and the secondary monitoring area through the lower opening of the main suction cylinder 1 and the lower openings of the multiple auxiliary suction cylinders 9, the auxiliary suction cylinder 9 is installed in the secondary monitoring area through the secondary fixing ring 15 and screws. The lower opening of the main suction cylinder 1 and the lower openings of the multiple auxiliary suction cylinders 9 filter the sucked air through the main cylinder filter 13 and the auxiliary cylinder filter 16 respectively, to prevent impurities in the air from entering the equipment and causing damage, thereby improving the service life of the equipment.
