Description

Technical Field

[0001] This utility model relates to the field of fire monitoring, specifically a flame alarm detection device for dealing with complex environments. Background Technology

[0002] Fire alarm detectors are the core equipment for fire early warning. They can monitor the initial characteristic signals of fire such as smoke, temperature and flame in the environment in real time and respond quickly. Their core function is to trigger alarms in time and link fire-fighting facilities to buy time for personnel evacuation and fire fighting, and reduce loss of life and property.

[0003] Fire alarm detectors primarily use cameras for fire detection. By capturing images of the monitored location, they determine the presence of a fire based on the captured images. This not only adapts to complex scenarios such as chemical plants and large warehouses, expanding coverage through visual monitoring, but also complements traditional detectors, enabling real-time fire confirmation and reducing false alarm losses. However, most fire alarm detectors are fixed in their installation, meaning the camera's shooting angle is fixed and cannot be adjusted. This makes them susceptible to significant environmental conditions, such as strong light interference, obstructions, and dust adhering to the lens, which directly reduce detection accuracy and lead to alarm delays.

Detailed Implementation

[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] like Figure 1-4 As shown, the present invention provides a flame alarm detection device for dealing with complex environments, including a controller, a fire alarm detector 4 electrically connected to the controller, a drive cylinder electrically connected to the controller, a first drive motor 5 electrically connected to the controller, a second drive motor 6 electrically connected to the controller, a mounting bracket 1, an adjustment bracket 2, and a filter assembly.

[0028] Mounting bracket 1 is used for mounting on a vehicle, wherein the controller is mounted on mounting bracket 1.

[0029] One end of the adjusting rod 2 is rotatably mounted on the mounting frame 1, wherein the first drive motor 5 is mounted on the mounting frame 1, and the rotating shaft of the first drive motor 5 is connected to one end of the adjusting rod 2, so as to drive the adjusting rod 2 to rotate relative to the mounting frame 1 through the first drive motor 5.

[0030] In this embodiment, the mounting frame 1 includes a support plate 11, a first clamping rod 12 and a second clamping rod 13 disposed on the bottom surface of the support plate 11. The first clamping rod 12 has a first through hole at the end away from the support plate 11, and the second clamping rod 13 has a second through hole at the end away from the support plate 11. One end of the adjusting rod 2 is disposed between the first clamping rod 12 and the second clamping rod 13, and one end of the adjusting rod 2 has a third through hole. The first drive motor 5 is fixedly disposed on the outer side wall of the first clamping rod 12. The rotating shaft of the first drive motor 5 passes through the first through hole, the third through hole and the second through hole. The rotating shaft of the first drive motor 5 is fixedly disposed in the third through hole (such as by a snap-fit ​​connection), so that the adjusting rod 2 can be driven to rotate by the rotating shaft of the first drive motor 5.

[0031] An adjustment frame 3 is set at the other end of the adjustment rod 2. The bottom end of the fire alarm detector 4 is rotatably mounted on the adjustment frame 3, and the second drive motor 6 is mounted on the adjustment frame 3. The rotation shaft of the second drive motor 6 is connected to the bottom end of the fire alarm detector 4 so as to drive the fire alarm detector 4 to rotate relative to the adjustment frame 3 through the second drive motor 6.

[0032] It should be understood that, since the first drive motor 5 drives the adjusting rod 2 to rotate and the second drive motor 6 drives the fire alarm detector 4, when the fire alarm detector 4 is interfered with or the image is unclear (such as strong light interference, obstacles, or other reasons that cause the image to be unclear at the original position), the controller controls the rotation shaft of the first drive motor 5 to drive the adjusting rod 2 and / or the second drive motor 6 to drive the fire alarm detector 4 to rotate, so as to rotate the fire alarm detector 4 to a position where the image can be clearly captured. This provides greater flexibility and can cope with different complex environments.

[0033] A light-filtering assembly is movably mounted on the top of the fire alarm detector 4 to filter the light from the camera 41 located at the top of the fire alarm detector 4. It should be understood that filtering the light from the camera 41 by the light-filtering assembly can filter out strong light and prevent strong light from affecting the image captured by the camera 41.

[0034] In this embodiment, the drive cylinder is located at the top of the fire alarm detector 4, and the telescopic rod of the drive cylinder is connected to the filter assembly so as to drive the filter assembly to move through the drive cylinder.

[0035] Preferably, the drive cylinder includes a first drive cylinder 7 and a second drive cylinder 8 respectively disposed on both sides of the top of the fire alarm detector 4, wherein the first drive cylinder 7 and the second drive cylinder 8 are arranged in parallel and spaced apart, and the extension and retraction directions of the extension rods of the first drive cylinder 7 and the second drive cylinder 8 are the same, and the extension and retraction direction of the extension rod of the first drive cylinder 7 is perpendicular to the shooting direction of the camera at the top of the fire alarm detector 4.

[0036] In this embodiment, the filter assembly includes a connector 9 and a filter element 10.

[0037] The connector 9 is connected to the telescopic rod of the first drive cylinder 7 and the telescopic rod of the second drive cylinder 8, so that the first drive cylinder 7 and the second drive cylinder 8 synchronously drive the connector 9 to rise and fall.

[0038] The filter element 10 is mounted on the connector 9, and the filter element 10 is detachably connected to the connector 9, allowing different filter elements 10 to be replaced as needed. It should be understood that when the image captured by the camera 41 of the fire alarm detector 4 is interfered with by strong light, the first drive cylinder 7 and the second drive cylinder 8 together drive the connector 9 and the filter element 10 to descend, so that the strong light can be filtered through the filter element 10.

[0039] Furthermore, the light-filtering component includes a connecting frame 101 and a filter 102. The side of the connecting frame 101 is threadedly connected to the connector 9 (allowing for the replacement of different connecting frames 101 as needed), and the connecting frame has a hollow hole. The filter 102 is disposed within the hollow hole of the connecting frame 101 for filtering light from the camera 41. It should be understood that the filter 102 filters strong light.

[0040] Preferably, the hollow hole is rectangular and the filter 102 is rectangular, wherein the length and width of the filter 102 are both greater than the length and width of the lens of the camera 41.

[0041] Furthermore, the side of the connecting frame 101 facing the camera 41 is provided with a cleaning scraper made of soft material. It should be understood that when the connecting frame 102 descends, the cleaning scraper contacts the lens of the camera 41, thereby cleaning dust from the camera 41 during the descent. In other words, the filter assembly can clean dust from the camera 41 while moving, preventing dust from affecting image capture. Of course, in some embodiments, the cleaning scraper is equipped with a brush to clean the camera lens.

[0042] In this embodiment, the adjustment frame 3 includes a mounting plate 31 disposed at the other end of the adjustment rod 2, a first clamping plate 32 and a second clamping plate 33 disposed on one side of the mounting plate 31, wherein the bottom end of the fire alarm detector 4 extends to provide an extension portion located between the first clamping plate 32 and the second clamping plate 33, the first clamping plate 32 is provided with a fourth through hole, the second clamping plate 33 is provided with a fifth through hole, and the extension portion is provided with a sixth through hole, the second drive motor 6 is fixedly disposed on the outer wall of the first clamping plate, and the rotating shaft of the second drive motor 6 passes through the fourth through hole, the sixth through hole and the fifth through hole, and the rotating shaft of the second drive motor 6 is fixedly disposed in the sixth through hole, so that the extension portion can be driven to rotate through the rotating shaft of the second drive motor 6, thereby driving the fire alarm detector 4 to rotate.

[0043] It is worth noting that the controller, fire alarm detector 4, drive cylinder, first drive motor 5 and second drive motor 6 in this embodiment can be implemented using products in the prior art, and their principles and structures will not be described in detail.

[0044] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
