Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to a fire smoke detector detection device that is easy to adjust. Background Technology

[0002] Smoke detectors are a core component of automatic fire alarm systems, used to detect smoke particles generated by fires in their early stages and issue timely alarm signals, buying time for evacuation and firefighting. Their working principle is based on optical, ionization, or physical sensing technology, triggering an alarm by monitoring changes in smoke concentration in the air.

[0003] Depending on the location of use, not all fire smoke detectors are fixed to the ceiling; some are fixed to the wall. Over time, dust will accumulate, and dust buildup in the detector's casing and ventilation system can cause detection failure. Therefore, fire smoke detectors need to be cleaned periodically. After cleaning, necessary functional tests should be performed, and those that fail to meet the requirements must not be reinstalled or used. However, since the installation location is high, it is not convenient to use a ladder to clean the fire smoke detectors, as this method is somewhat dangerous. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easily adjustable fire smoke detector detection device, which facilitates the cleaning and detection of fire smoke detectors on walls or ceilings.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 An easily adjustable fire smoke detector detection device includes a fitting hopper 1. A rectangular frame 2 is fixedly connected to the lower end of the fitting hopper 1. The rectangular frame 2 is divided into a smoke chamber and a filter chamber by a partition 3. A smoke generator 4 is fixedly connected inside the smoke chamber. Two mutually symmetrical fixed seats are rotatably connected inside the fitting hopper 1. A cleaning mechanism is detachably connected to the fixed seats. A drive mechanism for driving the fixed seats to rotate is fixedly connected to the outer wall of the fitting hopper 1. Two threaded holes 5 are opened on the fitting hopper 1. Threaded caps 6 are threadedly connected to the threaded holes 5. A filter mechanism is detachably connected inside the filter chamber. A sealing component for sealing the outlet of the filter chamber is installed on the rectangular frame 2. A telescopic component is installed below the fitting hopper 1.

[0021] like Figures 1 to 4As shown, the adjustable fire smoke detector detection device of this utility model can be used to adjust the orientation of the mounting bucket 1 through the telescopic component, thereby facilitating the mounting bucket 1 to fit against the wall or ceiling, so as to cover the corresponding fire smoke detector for cleaning and detection. After covering, the drive mechanism is activated by the remote control, causing the fixed base to rotate, which in turn drives the cleaning mechanism on the fixed base to rotate, thereby cleaning the dust and other debris adhering to the surface of the fire smoke detector. During this process, the filtration mechanism also operates, allowing the air inside the mounting bucket 1 to flow through the outlet of the filtration chamber. The filtration mechanism can also filter and intercept dust and other particles in the flowing air, preventing dust from flying around. Similarly, to prevent dust from falling back onto the fire smoke detector, after the fire smoke detector is cleaned, the filtration chamber is sealed using the sealing component, and the connection between the smoke chamber and the mounting bucket 1 is opened. At this time, the smoke generator 4 is activated, which generates smoke and disperses it inside the mounting bucket 1, thereby detecting whether the fire smoke detector is working properly.

[0022] like Figure 2 and Figure 3 As shown, the fixed base includes a rotating shaft 7 rotatably connected to the inner wall of the fitting bucket 1, a rectangular block 8 fixedly connected to the rotating shaft 7, a pulley 9 fixedly connected to the front end of the rotating shaft 7, and a threaded hole 10 opened on the rectangular block 8.

[0023] Specifically, rectangular block 8 and threaded hole 10 are used to restrict and fix the cleaning mechanism. Rotary shaft 7 is connected to the drive mechanism through pulley 9. When the drive mechanism is running, it can drive pulley 9 to rotate, thereby causing the cleaning mechanism on rectangular block 8 to rotate, so as to clean dust and other debris on the surface of the fire smoke detector.

[0024] like Figure 2 As shown, the cleaning mechanism includes a cylinder 11 slidably connected to a rectangular block 8, a cleaning brush 12 fixedly connected to the cylinder 11, a disc 13 at the front end of the cylinder 11, and a threaded rod 14 that matches the threaded hole 10 fixedly connected to the disc 13.

[0025] Specifically, after removing the threaded cap 6, rotating the disc 13 allows the threaded rod 14 to be removed from the threaded hole 10, making it easier to remove the cylinder 11 and the cleaning brush 12 for replacement. After fixing them in the reverse order, the drive mechanism operates, and the cylinder 11 moves and rotates with the rectangular block 8, causing the cleaning brush 12 to rotate and clean dust and other debris from the surface of the fire smoke detector.

[0026] like Figure 2As shown, the drive mechanism includes a mounting frame fixedly connected to the fitting bucket 1, a driver 15 fixedly connected to the mounting frame, a rotating shaft 16 fixedly connected to the output end of the driver 15, two pulleys 17 fixedly connected to the rotating shaft 16, and a rubber belt 18 adapted to the pulley 9 installed on the pulley 17.

[0027] Specifically, starting the driver 15 causes the second shaft 16 to rotate, which in turn drives the two pulleys 17 to rotate. Since the second pulley 17 is connected to the first pulley 9 by a rubber belt 18, it can drive the first pulley 9 to rotate, thereby causing the cleaning brush 12 on the cleaning mechanism to rotate.

[0028] like Figure 3 and Figure 4 As shown, the filtration mechanism includes a rectangular cylinder 19 slidably connected inside the filter chamber, a support plate 20 fixedly connected to the inner wall of the rectangular cylinder 19, a filter screen 21 fixedly connected between the support plate 20 and the rectangular cylinder 19, a blower fan 22 fixedly connected to the support plate 20, and a tightening bolt for fixing the rectangular cylinder 19 threadedly connected to the rectangular frame 2.

[0029] Specifically, the blower fan 22 blows air outward, thereby driving the airflow inside the sealing bucket 1. The flowing air is intercepted by the filter screen 21, which can prevent dust from flying around and reduce the dust from re-adhering to the surface of the fire smoke detector. Turning and tightening the bolt can release the fixing effect on the rectangular cylinder 19, thus making it easy to clean and replace the filter screen 21 and the blower fan 22.

[0030] like Figure 4 As shown, the sealing assembly includes a groove 23 formed on a rectangular frame 2, a sealing plate 24 slidably connected to the groove 23, the sealing plate 24 slidably connected to the partition 3, and an electric telescopic rod 25 fixedly connected to the inner wall of the rectangular frame 2, the output end of the electric telescopic rod 25 being fixedly connected to the sealing plate 24.

[0031] Specifically, when cleaning the dust and other debris adhering to the surface of the fire smoke detector, the sealing plate 24 is located in the smoke chamber, separating the smoke chamber from the bonding hopper 1. Dust will not fall onto the smoke generator 4. After cleaning the surface of the fire smoke detector, the electric telescopic rod 25 is activated to push the sealing plate 24 from the smoke chamber along the slide 23 into the filter chamber. At this time, the smoke chamber is connected to the bonding hopper 1, while the filter chamber is separated from the bonding hopper 1. The smoke generator 4 is activated, and the generated smoke will remain in the bonding hopper 1 and the smoke chamber, thereby testing whether the fire smoke detector can be used normally.

[0032] like Figure 2As shown, the telescopic assembly includes a connecting rod 26 rotatably connected to the lower end of the fitting bucket 1. The lower end of the connecting rod 26 is fixedly connected to a friction self-locking multi-stage telescopic rod 29. Two mutually perpendicular U-shaped pipe clamps 27 and 28 are fixedly connected to the fitting bucket 1. The U-shaped pipe clamps 27 and 28 are used to fix the connecting rod 26.

[0033] Specifically, the connecting rod 26 is connected to the U-shaped pipe clamp 27. At this time, the connecting rod 26 and the fitting bucket 1 are perpendicular to each other, which facilitates the maintenance and inspection of the fire smoke detector on the top of the wall. The connecting rod 26 is connected to the U-shaped pipe clamp 28. At this time, the connecting rod 26 and the fitting bucket 1 are parallel to each other, which facilitates the maintenance and inspection of the fire smoke detector on the wall. The friction self-locking multi-stage telescopic rod 29 (similar to the telescopic locking principle of a fishing rod) can be adjusted according to the installation position of the fire smoke detector.

[0034] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
