[0028] To address the problem of poor shooting performance of existing explosion-proof cameras in dimly lit environments, this application provides an explosion-proof camera device.
[0029] like Figure 1 and Figure 2 As shown, the explosion-proof camera device includes a housing 10, an image acquisition device, a microphone 30, a speaker 40, and a supplementary lighting device 50. The housing 10 includes an explosion-proof shell 11 and an explosion-proof glass 12. The explosion-proof shell 11 has an inner cavity, a first mounting portion 13, a second mounting portion 14, and a first mounting opening. The inner cavity communicates with the first mounting opening, and the explosion-proof glass 12 is disposed at the first mounting opening. The image acquisition device is disposed in the inner cavity, with its image acquisition end positioned opposite to the explosion-proof glass 12. The microphone 30 is disposed on the first mounting portion 13 and is electrically connected to the sound collection portion of the image acquisition device. The speaker 40 is disposed on the second mounting portion 14 and is electrically connected to the sound playback portion of the image acquisition device. The supplementary lighting device 50 is disposed on the explosion-proof shell 11 for supplementary lighting.
[0030] Applying the technical solution of this embodiment, the supplementary lighting device 50 is installed on the explosion-proof housing 11 to provide supplementary lighting for the image acquisition device. When the explosion-proof camera is in a relatively dark environment, the supplementary lighting device 50 can be activated to provide supplementary lighting for the image acquisition device, enabling it to capture clear images, thereby solving the problem of poor shooting performance of explosion-proof cameras in dark environments in the prior art. Simultaneously, the microphone 30 and the speaker 40 are electrically connected to the sound collection unit and sound playback unit of the image acquisition device, respectively, so that the microphone 30 collects sound from the coal mine environment and the speaker 40 plays the sound emitted by the image acquisition device.
[0031] In this embodiment, the image acquisition device is a camera.
[0032] Optionally, the explosion-proof camera device also includes a support structure. This support structure is housed within the internal cavity to support the image acquisition device. This design makes the assembly and disassembly of the image acquisition device easier and simpler, reducing the difficulty of assembly and disassembly and also reducing the workload of the personnel.
[0033] Optionally, the support structure has a mounting recess, into which at least a portion of the image acquisition device extends and is positioned and engaged; there is one support structure; or, there are multiple support structures, spaced apart along the circumference and / or axial direction of the image acquisition device. This arrangement increases the contact area between the support structure and the image acquisition device, thereby improving the stability of the support structure in supporting the image acquisition device. Furthermore, it allows for greater flexibility in selecting the number and arrangement of support structures to meet different usage requirements and working conditions, and also enhances the processing flexibility for operators.
[0034] like Figure 1 and Figure 2 As shown, the explosion-proof housing 11 includes a housing body 15 and a rear cover 16. The housing body 15 has a first mounting port and a second mounting port, the second mounting port being opposite to the first mounting port and communicating with the inner cavity. The rear cover 16 is located at the second mounting port and has a flared opening communicating with the second mounting port. This design makes the maintenance and replacement of the image acquisition device easier and simpler, reducing the labor intensity of personnel; it also simplifies the structure of the explosion-proof housing 11, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the explosion-proof housing 11.
[0035] In this embodiment, when maintenance or replacement of the image acquisition device is required, simply remove the rear cover 16 from the housing body 15. After the maintenance or replacement of the image acquisition device is completed, the rear cover 16 can be reinstalled on the housing body 15.
[0036] Optionally, the flared opening extends along the length of the housing body 15, and there is only one flared opening; alternatively, there are multiple flared openings, spaced apart along the length and / or width of the rear cover 16. This allows workers to observe the interior of the housing body 15 through the flared openings for subsequent maintenance. Furthermore, this arrangement provides greater flexibility in selecting the number and arrangement of the flared openings to meet different usage requirements and working conditions, and also improves the processing flexibility for workers.
[0037] In this embodiment, the rear cover 16 is a circular cover with two flared openings, which are spaced apart along the length of the rear cover 16.
[0038] It should be noted that the number of bell mouths is not limited to this and can be adjusted according to working conditions and usage requirements.
[0039] Optionally, the flare can be three, four, five, six, or more.
[0040] In this embodiment, the supplementary lighting device 50 is a supplementary light lamp, which is positioned close to the first mounting port. This arrangement simplifies the structure of the supplementary lighting device 50, making it easier to manufacture and implement, thus reducing manufacturing costs and difficulties. Simultaneously, the aforementioned positioning of the supplementary light lamp further enhances the image capture clarity of the image acquisition device.
[0041] Optionally, the first mounting portion 13 includes a first cylindrical body 131 and a second cylindrical body 132 connected to each other. The second cylindrical body 132 is connected to the outer surface of the explosion-proof housing 11 through the first cylindrical body 131, and the inner diameter of the first cylindrical body 131 is smaller than the inner diameter of the second cylindrical body 132. And / or, the second mounting portion 14 includes a third cylindrical body 141 and a fourth cylindrical body 142 connected to each other. The fourth cylindrical body 142 is connected to the outer surface of the explosion-proof housing 11 through the third cylindrical body 141, and the inner diameter of the third cylindrical body 141 is smaller than the inner diameter of the fourth cylindrical body 142. Thus, the above arrangement makes the structure of the first mounting portion 13 and / or the second mounting portion 14 simpler, easier to process and implement, and reduces the processing cost and difficulty of the housing 10.
[0042] In this embodiment, the explosion-proof camera device further includes an alarm module and a control module. The alarm module is used to issue an alarm signal, and the control module is electrically connected to both the alarm module and the image acquisition device. Specifically, when the explosion-proof camera device is within the protected area, if the image acquisition device captures a person or vehicle, the control module controls the alarm module to issue an alarm signal.
[0043] Optionally, the explosion-proof camera device also includes a drying device disposed within the explosion-proof housing 11; and / or, the explosion-proof camera device also includes a POE power supply electrically connected to the image acquisition device for powering the image acquisition device.
[0044] Optionally, the explosion-proof housing 11 is made of stainless steel.
[0045] Optionally, the explosion-proof camera device also includes an observation window. This observation window is located at the flared opening. This allows personnel to observe the interior of the housing body 15 through the observation window for subsequent maintenance. Furthermore, this design allows for greater flexibility in the number and arrangement of observation windows to meet different usage needs and working conditions, and also improves the processing flexibility of the personnel.
[0046] Optionally, there can be one observation window; or, there can be multiple observation windows, with each observation window corresponding to a different horn opening. This arrangement allows for greater flexibility in selecting the number of observation windows to meet different usage needs and working conditions, and also improves the processing flexibility of the workers.
[0047] In this embodiment, there are two observation windows, and the two observation windows are set one-to-one with the two horn openings.
[0048] It should be noted that the number of observation windows is not limited to this and can be adjusted according to working conditions and usage requirements.
[0049] Optionally, the number of viewing windows may be three, four, five, six, or more.
[0050] Optionally, the explosion-proof glass 12 is an IR-CUT dual filter. Specifically, the IRCUT dual filter consists of an infrared cut-off filter and a full-spectrum optical glass. When there is sufficient light during the day, the infrared cut-off filter works, and the CCD reproduces true colors. When there is insufficient light at night, the infrared cut-off filter automatically moves away, and the full-spectrum optical glass starts working, allowing the CCD to make full use of all light, thereby greatly improving infrared performance, but increasing the cost of the camera.
[0051] In this embodiment, the explosion-proof enclosure 11 serves to isolate the sparks and arcs generated by the electrical components inside the enclosure from the explosive mixture outside the enclosure, and can withstand the explosion pressure generated when the explosive mixture entering the enclosure is ignited by the sparks and arcs of the electrical equipment inside the enclosure. At the same time, the explosion-proof enclosure 11 can prevent the explosion products inside the enclosure from propagating to the explosive mixture outside the enclosure, and will not cause the explosive mixture outside the enclosure to burn or explode.
[0052] In this embodiment, the explosion-proof camera device uses deep learning hardware and algorithms to intelligently analyze and identify real-time video images. It can classify and detect personnel and vehicles, support boundary crossing detection, area intrusion detection, and detection of entering or leaving the area. It can detect anomalies in perimeter protection and designated area perimeter protection in real time. It provides voice alarms through the microphone 30 and speaker 40 set in the explosion-proof housing 11 and the alternating flashing lights, providing accurate prompts, real-time warnings, and sound and light deterrence.
