[0007] Through the above technical scheme:

[0008] When in use, the camera device as the core component of the machine room safety monitoring can monitor all kinds of conditions in the machine room such as equipment running state, environmental parameters and potential safety hazards, etc. in real time all day long. The high-resolution camera equipped with the camera device has the ability to capture clear images and videos, which can ensure that the operation and maintenance personnel can accurately master the dynamic information of the machine room at any time.

[0009] In view of the need to ensure that the camera device maintains stability and durability in various complex environments, the camera device is externally equipped with a protection cover. The protection cover is made of high-strength and high-temperature-resistant metal material, which can effectively resist physical impact, withstand high-temperature invasion and prevent chemical corrosion, and can protect the camera device in all directions, so that it can still operate normally and stably even in harsh working conditions. The front wall of the protection cover is specially designed as a transparent protective plate made of high-transmittance and wear-resistant material, which provides an additional layer of protection without affecting the camera device's field of view. The transparent protective plate can effectively prevent dust, dirt and other pollutants from adhering to the camera lens, and can also effectively prevent the invasion of smoke and harmful gases, ensuring that the camera device can output clear images in any situation.

[0010] In order to properly handle the problem of dust accumulation that may frequently occur in the machine room, the protective cover of the camera device is equipped with an advanced automatic cleaning system. Once the transparent protective plate surface is attached with dust or other contaminants, affecting the working efficiency of the camera device, the operator can start the first motor. The first motor drives the installation plate to rotate through the first shaft and the connecting block. The installation plate is internally provided with a roller brush. Under the driving of the installation plate, the roller brush moves back and forth on the surface of the transparent protective plate in a specific mode, and carries out efficient cleaning work on the dust on the transparent protective plate.

[0011] When a fire accident breaks out, the protective cover of the camera device and the automatic cleaning system will play an irreplaceable key role. A large amount of smoke and dust generated by the fire will accumulate on the surface of the transparent protective plate in a very short time, causing serious shielding of the camera device's field of view. At this critical moment, the automatic cleaning system can be started immediately, and the roller brush can quickly remove dust to ensure that the camera device can continuously and stably provide clear images. It is known that these clear images are crucial for fire emergency response, which can help firefighters and machine room operators to understand the fire development situation at the first time, and provide guidance for the quick escape of the disaster victims. Moreover, the camera device can also transmit the real-time situation of the fire scene to the remote monitoring center through the real-time video transmission function, and provide valuable information support for the rescue work.

[0012] The angle adjusting assembly comprises a second motor, a second shaft and a second gear, the second motor is fixed on the installation plate, the second shaft is connected to the output end of the second motor, the second gear is installed on the outer wall of the second shaft, and the first gear and the second gear are matched.

[0013] Preferably, the cleaning assembly comprises a dust collecting plate, a dust collecting box, a duct and an air extractor, the dust collecting plate is arranged in the installation groove, the dust collecting box is fixed on the side wall of the installation plate, a plurality of filter screens are arranged in the dust collecting box, the duct is connected between the dust collecting plate and the air inlet end of the dust collecting box, the duct adopts a multi-head structure, and the air extractor is installed at the air outlet end of the dust collecting box.

[0014] Through the above technical solutions:

[0015] In use, the second motor and the air extractor are started simultaneously when performing cleaning. This synchronous starting mode ensures that the cleaning process and the dust suction process are synchronized, greatly improves the cleaning efficiency, and effectively avoids the secondary pollution problem of dust.

[0016] The second motor after starting drives the second gear to rotate by the second rotating shaft. Since the first gear and the second gear are engaged with each other, the rotation of the second gear will drive the first gear to rotate synchronously. This gear transmission architecture design ensures that the roller brush can rotate continuously at a stable speed, and with the fine adjustment of the angle adjusting assembly, the roller brush is fully utilized, avoiding the situation of being stuck, further improving the cleaning efficiency.

[0017] In the process of rotating cleaning of the roller brush, the air extractor performs cleaning operation on the brush body of the roller brush located on one side of the installation groove through the conduit. The conduit adopts a multi-head structure, which can more comprehensively cover the cleaning area of the roller brush, and effectively ensure that dust is efficiently sucked in.

[0018] The air extractor generates a negative pressure environment, and forcibly sucks the dust on the roller brush away through the conduit to prevent the dust from accumulating during the cleaning process. The sucked dust is transported to the inside of the dust collection box through the conduit. The dust collection box is equipped with multiple filter screens, which are used to capture dust particles to prevent dust from blocking the air extractor, thereby ensuring that the discharged air is clean and pollution-free.

[0019] Through the coordinated operation of the above components, the bristles on the roller brush can fully exert the cleaning function, effectively improve the cleaning efficiency, and firmly ensure the cleaning effect of the transparent protective plate. At the same time, the air extractor timely removes the dust on the roller brush through the conduit, which guarantees the normal operation of the roller brush and prolongs its service life.

[0020] This ingenious design not only significantly improves the cleaning efficiency, but also effectively ensures the long-term and stable operation of the camera device and its protective cover, laying a reliable foundation for the safe monitoring of the machine room. With the tacit cooperation between multiple components, the cleaning process becomes more efficient and thorough, effectively ensuring the clear vision of the camera device and the normal use of the equipment.

[0021] Preferably, the clamping assembly comprises a clamping groove and a clamping block, the clamping groove is opened on the side wall of the bearing plate close to the protective cover, and the clamping block is installed on the outer wall of the protective cover, and the clamping groove and the clamping block are matched with each other.

[0022] Specifically, the connection structure between the bearing plate and the protective cover is optimized, and the combination mode of the clamping groove and the clamping block is used to achieve rapid and convenient installation and disassembly. Such unique connection means not only simplifies the assembly steps of the equipment, but also greatly enhances the convenience in transportation, maintenance and maintenance, providing strong support for the operation and maintenance of the whole equipment.

[0023] Preferably, the bottom end of the camera device is provided with a support plate, the support plate is provided with a smoke alarm, the detection end of the smoke alarm is provided with a suction pump, and the air inlet end of the suction pump is connected with a suction pipeline.

[0024] Specifically, the support plate serves as an integrated installation platform of the camera device and the smoke alarm, which not only provides solid and reliable mechanical support for the two, but also can flexibly and freely regulate the position of the camera device through the linkage with the device with the functions of lifting and left-right translation, thereby greatly widening the working interval of the camera device and achieving more comprehensive and extensive monitoring coverage.

[0025] The smoke detection system uses the active air suction design concept, the air suction pump continuously and uninterruptedly runs, and the air sample is transmitted to the detection end of the smoke alarm in a high-efficiency manner by means of the air suction pipeline. Compared with the traditional passive detection mode, this design can detect the presence of smoke at a faster speed and higher accuracy, significantly improving the timeliness and reliability of fire warning, and laying a solid foundation for fire prevention work.

[0026] The smoke alarm is internally equipped with a high-sensitivity smoke sensor, which can capture smoke particles in the air at an extremely fast speed. Once the smoke concentration exceeds the pre-set threshold, the alarm will immediately trigger the sound and light alarm signal, timely alerting relevant personnel to take emergency measures, effectively preventing and responding to fire hazards, and ensuring personnel and property safety.

The transparent protective plate 3 can not only effectively prevent dust, dirt and other pollutants from adhering to the camera lens, but also effectively prevent the invasion of smoke and harmful gases, and can ensure that the camera device 1 can output clear images in any situation.

[0043] In order to properly handle the problem of frequent dust accumulation in the machine room, the protective cover 2 of the camera device 1 is equipped with an advanced automatic cleaning system. Once the transparent protective plate 3 is attached with dust or other pollutants, affecting the working efficiency of the camera device 1, the operator can start the first motor 9. The first motor 9 drives the mounting plate 7 to rotate through the first rotating shaft 10 and the connecting block 11. The mounting plate 7 is internally provided with a roller brush 12, which moves back and forth on the surface of the transparent protective plate 3 in a specific mode under the driving of the mounting plate 7, and performs efficient cleaning work on the dust on the transparent protective plate 3.
