Description

Technical Field

[0001] This utility model relates to the field of light sensing equipment technology, and in particular to an explosion-proof multi-light sensing camera. Background Technology

[0002] In flammable and explosive environments such as petrochemical and mining industries, multispectral sensors serve as important safety monitoring devices, undertaking key tasks such as environmental perception, equipment status monitoring, and personnel identification.

[0003] Existing explosion-proof cameras generally adopt increased safety or explosion-proof designs, which achieve basic explosion protection by filling the metal shell with epoxy resin. Although this can meet the basic explosion-proof certification requirements, stress concentration is easily generated at the corners of the traditional square shell. When subjected to impact, it is easy to cause structural deformation of the shell, resulting in mechanical damage to the internal circuit boards and functional modules.

[0004] When the equipment is working continuously, the sensors and related electronic components generate accumulated heat. Conventional heat dissipation designs are unable to establish an effective heat conduction path, which may lead to local temperature rise exceeding the safe range and affect the long-term reliability of the equipment in special environments.

[0005] Based on the above problems, those skilled in the art have proposed an explosion-proof multi-light sensor camera. Utility Model Content

[0006] This utility model discloses an explosion-proof multi-light sensor camera, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0056] Lens protective cover 15 located above the sensor base plate 14;

[0058] A sensor circuit board 17 is spaced apart from the PCB circuit board 16, and a visible light sensor 1701 is provided on the sensor circuit board 17 that passes through the lens protective sleeve 15.

[0059] The protective plate 19 is assembled to the bottom surface of the bottom shell 18 by means of a movable connection or screw fixing;

[0060] The front surface of the housing 11 is provided with a protective part 1101 and an operating part 1102 distributed vertically. The protective part 1101 has a light-transmitting hole, and the operating part 1102 is embedded in the front panel 12.

[0061] The inner cavity of the housing 11 is provided with a placement part 1103 with a through-type speaker hole 1104;

[0062] The front panel 12 is divided into a lower sensing area 1201 and an upper button area 1202;

[0063] The protective lens 13 is provided with a light-transmitting part 1301 corresponding to the light-transmitting hole of the protective part 1101;

[0064] The sensing base plate 14 is provided with:

[0065] Hardened keyboard membrane 1401 corresponding to key area 1202;

[0066] A card reader module that works in conjunction with the sensing area 1201;

[0067] To avoid the notch 1402 in the placement part 1103;

[0068] The inner wall of the lens protective sleeve 15 is provided with a ring-shaped lens overpass reinforcing rib 1501;

[0069] PCB circuit board 16 includes:

[0070] Dual alarm relay 1601 integrated on the front of PCB circuit board 16;

[0071] A heat sink 1602 and a micro switch 1603 are integrated on the back of the PCB circuit board 16. The heat sink 1602 is connected to the sensor circuit board 17 to conduct heat.

[0072] The bottom shell 18 is provided with:

[0073] The heat-conducting metal 1801 is in contact with the heat sink 1602;

[0074] Tamper-proof switch 1802 that triggers micro switch 1603;

[0075] Waterproof adhesive strip 1803 is installed along the edge;

[0076] The recessed hanging groove on the back is 1804;

[0077] The guard plate 19 is provided with:

[0078] Through slot 1901 is provided to avoid the tamper switch 1802;

[0079] Mounting plate 1902 that mates with mounting slot 1804;

[0080] A connecting plate 1903 extending vertically from the bottom, and screw through holes provided on the connecting plate 1903 for assembly;

[0081] A speaker 110 corresponding to the speaker hole 1104 is fixedly installed inside the placement part 1103;

[0082] Working principle: The camera body 1 is connected to the housing 11 and the bottom housing 18 by screws to form an explosion-proof cavity. The rounded corners of the housing 11, combined with the internal reinforcing rib structure, effectively disperse external impact stress and improve the overall compressive strength. The front panel 12 is flexibly connected to the housing 11 through the buffer pad 1203. The sensing area 1201 at the bottom of the front panel works with the card reader module of the sensing base plate 14 to realize signal acquisition. The button area 1202 at the top realizes touch operation through the hardened keyboard membrane 1401. The visible light sensor 1701 extends outward through the lens protective sleeve 15 with lens over-control reinforcing rib 1501 and receives external light through the light-transmitting part 1301 of the protective lens 13. The light-transmitting hole of the protective part 1101 and the light-transmitting part 1301 form a double protection structure, which ensures light transmittance while blocking external dust from entering.

[0083] When the camera is working, the dual alarm relays 1601 on the front of the PCB circuit board 16 monitor the circuit status in real time, and the heat sink 1602 on the back conducts the heat generated by the sensor circuit board 17 to the heat dissipation conductive metal 1801 of the bottom shell 18 for rapid heat dissipation, preventing internal temperature accumulation. The waterproof adhesive strip 1803 on the edge of the bottom shell 18 is tightly attached to the shell 11 to form an explosion-proof sealing layer, preventing flammable gases or liquids from seeping in.

[0084] When the protective plate 19 is illegally disassembled, the anti-tamper switch 1802 triggers the micro switch 1603 to cut off the power and start the alarm. The speaker 110 in the placement part 1103 transmits the alarm sound to the outside through the through-hole 1104.

[0085] The mounting slot 1804 and the mounting plate 1902 of the guard plate 19 can be used to facilitate the mounting of this device. The bending design of the connecting plate 1903 can enhance the impact resistance of the bottom of the guard plate 19. At the same time, the guard plate 19 can be stably connected to the housing 11 by means of screw connection, thereby providing protection for the bottom shell 18.

[0086] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
