Description

Technical Field

[0001] This invention relates to the field of camera technology, and more specifically to an explosion-proof industrial camera. Background Technology

[0002] Explosion-proof industrial cameras are special monitoring devices designed for flammable and explosive hazardous environments (such as petrochemical, natural gas, coal mine, and pharmaceutical sites). Their core feature is that the entire unit (including the casing, circuitry, and terminals) employs an explosion-proof structure, effectively blocking the spread of flames and explosions when internal electrical sparks or high temperatures occur, preventing the ignition of external flammable gases or dust. Simultaneously, these cameras are typically equipped with high-strength stainless steel or aluminum alloy explosion-proof covers, explosion-proof windows (such as thickened explosion-proof glass), and impact-resistant sealing structures. They also integrate high-definition imaging, infrared night vision, and wide dynamic range functions to ensure continuous and stable operation under extreme conditions, achieving safe and visual monitoring of high-risk areas.

[0003] Existing explosion-proof industrial cameras, when applied in special industrial environments with severe external air pressure fluctuations (such as high-pressure relief areas, near flare equipment, large fan outlets, areas affected by explosion shock waves, or compression or exhaust sections with frequent start-stop cycles), often experience significant mechanical vibrations or overall shaking due to transient strong airflows or periodic pressures. This shaking not only causes image jitter, blurring, or even interruption of the video feed, severely affecting the clarity and continuity of real-time monitoring, but may also lead to loosening of internal optical components, fatigue failure of sealing structures, or even bracket breakage or shell damage due to long-term alternating stress, thereby threatening the explosion-proof integrity and service life of the equipment. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a solution for an explosion-proof industrial camera. This solution effectively addresses the problem that existing explosion-proof industrial cameras are susceptible to vibration due to strong airflow or pressure pulsations in environments with drastic pressure fluctuations (such as high-pressure relief zones, fan outlets, or explosion impact areas). This vibration can cause image jitter, blurring, or even interruption, and long-term vibration may also lead to loosening of optical components, sealing failure, or structural damage, jeopardizing explosion-proof performance and equipment lifespan.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an explosion-proof industrial camera, including a mounting base. A camera body is mounted on the top front side of the mounting base. A protective assembly is mounted on the outer surface of the mounting base. The protective assembly includes a mounting plate. Buffer air cushions are fixedly connected to the left and right sides of the front side of the mounting plate. Fixed boxes are fixedly connected to the left and right sides of the mounting base. A long rod extends through the rear side of the inner cavity of each fixed box. A connecting rod is rotatably connected to the left side of the inner cavity of the fixed box. Running plates are fixedly connected to opposite ends of the connecting rod and the long rod. A running round rod is fixedly connected to opposite sides of the two running plates. A top plate is slidably connected to the inner cavity of the fixed box. The bottom of the top plate is rotatably connected to the outer surface of the running round rod. A limit frame is fixedly connected to the inner cavity of the fixed box. An inflatable ball is mounted on the top of the limit frame and the inner cavity of the fixed box.

[0006] Furthermore, a hose is connected to one side of the inflatable ball, one end of the hose is connected to a cushioning air cushion, a pressure sensor is installed on the top of the mounting plate, and a solenoid valve is installed on the front side of the cushioning air cushion.

[0007] Furthermore, a welding seat is fixedly connected to the front side of the mounting base, and a threaded rod is rotatably connected to the front side of the welding seat. Two threaded plates are threadedly connected to the outer surface of the threaded rod. The rear side of the threaded plates is slidably connected to the welding seat, and a protective plate is fixedly connected to the top of the threaded plates.

[0008] Furthermore, protective boxes are fixedly connected to both the left and right sides of the mounting base, and long boxes are fixedly connected to both the left and right sides of the mounting base. A running rod is rotatably connected to the inner cavity of the long box.

[0009] Furthermore, the inner cavity of the protective box is rotatably connected to a guide rod, and the outer surfaces of the guide rod, the running rod, and the threaded rod are respectively equipped with first pulleys. The four first pulleys are connected by belt drive, and the inner cavity of the protective box is rotatably connected to two rotating rods.

[0010] Furthermore, a motor is fixedly connected to the inner cavity of the protective box, and the output shaft of the motor is fixedly connected to the rear end of the rotating rod on the left side.

[0011] Furthermore, two bevel gears are fixedly connected to the outer surfaces of the rotating rod and the guide rod, and the two bevel gears mesh with each other.

[0012] Furthermore, gears are fixedly connected to the outer surfaces of the two rotating rods respectively, and the two gears mesh. A guide plate is fixedly connected to the outer surface of the rotating rod, and a mounting rod is fixedly connected to the front side of the guide plate.

[0013] Furthermore, a positioning plate is fixedly connected to the front end of the mounting rod, and one side of the positioning plate is fixedly connected to the buffer air cushion. Second pulleys are respectively installed on the outer surfaces of the rotating rod and the long rod, and the two second pulleys are connected by belt drive.

[0014] Furthermore, a signal conversion device is mounted on the top of the mounting base.

[0015] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By setting up protective plates and buffer air cushions in the protective components, the camera can be dynamically wrapped and buffered with a fast response and tight fit under special working conditions of violent external airflow fluctuations (such as high pressure release, explosion shock wave, start-up and shutdown of large wind turbines or flare combustion area). When the sensor detects abnormal pressure change, the protection function is activated immediately, so that the protective plate closes first, building the first physical barrier. Simultaneously, the buffer air cushion deploys and inflates, forming a highly elastic and deformable buffer layer on the outside of the protective plate. This effectively absorbs and dissipates airflow energy. This dual-layer protection not only significantly suppresses the shaking and slight vibration of the entire machine caused by strong winds, periodic pressure, or transient shock waves, but also fundamentally isolates the high-speed airflow from directly impacting the lens window, housing seams, and heat dissipation holes. This avoids image jitter, seal failure, or loosening of internal components caused by airflow disturbances. More importantly, while enhancing the equipment's anti-interference capabilities, this protective component also strengthens its structural integrity and operational continuity in extreme environments, ensuring that the monitoring image remains clear and stable, providing reliable visual protection for safe production and emergency response.

[0016] 2. The protective components also feature guide plates, mounting rods, and other structures, allowing the buffer air cushion and protective plate to retract and fit snugly against the camera body under normal operating conditions. This prevents heat buildup caused by long-term coverage, ensuring efficient heat dissipation during normal operation while also facilitating maintenance. This further optimizes the long-term performance of the camera in complex industrial environments.

[0017] 3. In addition, the inflatable structure in the protective assembly, consisting of a top plate, a running rod, and an inflatable ball, can trigger the inflation process of the buffer air cushion while the protective plate is unfolding, realizing a rapid response mechanism of inflating as soon as it is unfolded. This not only ensures that the buffer air cushion expands rapidly at critical moments to provide effective cushioning, but also forms a flexible anti-drop protective layer in extreme cases (such as when the camera is accidentally dropped due to strong winds or external forces). The buffer air cushion absorbs the impact energy, and the protective plate disperses the impact stress. The synergistic effect of the two significantly reduces the risk of equipment damage, providing comprehensive and multi-layered safety protection for the camera and greatly improving its usability and durability in harsh scenarios.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] The present invention will be further described below with reference to embodiments.

[0025] See attached document Figure 1-8 The system includes a mounting base 1, which can be installed with an external installation environment and can be tilted and adjusted according to the actual installation environment. A camera body 2 is installed on the top front side of the mounting base 1. The camera body 2 can be an explosion-proof model. A protective component 3 is installed on the outer surface of the mounting base 1. The protective component 3 includes a mounting plate 31, which is fixedly connected to the top front side of the mounting base 1. Buffer air cushions 32 are fixedly connected to the left and right sides of the front side of the mounting plate 31. Fixing boxes 33 are fixedly connected to the left and right sides of the mounting base 1. A long rod 34 is provided through the rear side of the inner cavity of the fixing box 33. The contact area between the long rod 34 and the fixing box 33 is rotatably connected to each other through bearings. A connecting rod 35 is rotatably connected to the left side of the inner cavity of the fixing box 33. A running plate 36 is fixedly connected to the opposite end of the connecting rod 35 and the long rod 34, respectively.

[0026] See attached document Figure 2-8 Two running plates 36 are fixedly connected to a running rod 38 on opposite sides. A top plate 37 is slidably connected to the inner cavity of the fixed box 33. The bottom of the top plate 37 is rotatably connected to the outer surface of the running rod 38. A limit frame 330 is fixedly connected to the inner cavity of the fixed box 33. A through cavity is provided on one side of the limit frame 330 to facilitate the movement of the top plate 37. An inflatable ball 39 is installed on the top of the limit frame 330 and the inner cavity of the fixed box 33. The top plate 37 and the inflatable ball 39 cooperate with each other to facilitate repeated squeezing and inflation of the inflatable ball 39. The top plate 37 is convex. A hose 310 is connected to one side of the inflatable ball 39.

[0027] See attached document Figure 3-8One end of the hose 310 is connected to the cushioning air pad 32, which is semi-circular. A pressure sensor 326 is installed on the top of the mounting plate 31. The pressure sensor 326 is used to detect the external air pressure. The type of air pressure sensor can be selected. A solenoid valve 329 is installed on the front side of the cushioning air pad 32. The solenoid valve 329 is used to release air, so that the cushioning air pad 32 can be folded and stored after use. A welding seat 311 is fixedly connected to the front side of the mounting base 1. A threaded rod 312 is rotatably connected to the front side of the welding seat 311. The outer surface of the threaded rod 312 has two external thread sections arranged in opposite directions. Two threaded plates 313 are threadedly connected to the outer surface of the threaded rod 312. The area of ​​the threaded plate 313 in contact with the threaded rod 312 has matching internal threads. The rear side of the threaded plate 313 is slidably connected to the welding seat 311.

[0028] See attached document Figure 1-7 A protective plate 314 is fixedly connected to the top of the threaded plate 313, and the protective plate 314 cooperates with the camera body 2. Protective boxes 315 are fixedly connected to both sides of the mounting base 1. Long boxes 331 are fixedly connected to both sides of the mounting base 1. A running rod 316 is rotatably connected to the inner cavity of the long box 331. A guide rod 317 is rotatably connected to the inner cavity of the protective box 315. First pulleys 318 are respectively installed on the outer surfaces of the guide rod 317, the running rod 316, and the threaded rod 312. The four first pulleys 318 are connected by belt drive. Two rotating rods 319 are rotatably connected to the inner cavity of the protective box 315. Several guide plates are fixedly connected to the inner cavity of the protective box 315 and the top of the mounting base 1. The guide plates are rotatably connected to the rotating rods 319 and the guide rods 317. A motor 320 is fixedly connected to the inner cavity of the protective box 315.

[0029] See attached document Figure 2-7 The output shaft of the motor 320 is fixedly connected to the rear end of the left rotating rod 319. Two bevel gears 328 are fixedly connected to the outer surfaces of the rotating rod 319 and the guide rod 317, respectively. The two bevel gears 328 mesh. Gears 321 are fixedly connected to the outer surfaces of the two rotating rods 319, respectively, and the two gears 321 mesh. A guide plate 322 is fixedly connected to the outer surface of the rotating rod 319. A mounting rod 323 is fixedly connected to the front side of the guide plate 322. A positioning plate 324 is fixedly connected to the front end of the mounting rod 323.

[0030] See attached document Figure 1-7One side of the positioning plate 324 is fixedly connected to the buffer air cushion 32. The outer surfaces of the rotating rod 319 and the long rod 34 are respectively equipped with second pulleys 325. The two second pulleys 325 are connected by belt drive. The top of the mounting base 1 is equipped with a signal conversion device 327. The signal conversion device 327 is a sensor or controller, etc., which is a module or device that can receive signals from the motor 320, the solenoid valve 329 and the pressure sensor 326. The signal conversion device 327 is electrically connected to the pressure sensor 326, the motor 320 and the solenoid valve 329 respectively.

[0031] The protective component 3 also includes a guide plate 322, a mounting rod 323, and other structures, which allow the buffer air cushion 32 and the protective plate 314 to be stably retracted and tightly fitted to the outer contour of the camera body 2 under normal operating conditions. This storage design not only ensures that the protective unit completely avoids the lens window, heat dissipation holes, and interface areas when it is not inactive, but also effectively avoids problems such as heat accumulation, excessive internal temperature rise, or condensation retention caused by long-term coverage. This ensures that the core electronic components of the camera (such as the image sensor, main control chip, and power module) are always within a safe operating temperature range, maintaining their imaging performance and operational stability.

[0032] Specifically, when the pressure sensor 326 detects fluctuations in external gas pressure, it starts the motor 320 via the signal conversion device 327. The motor 320 drives the rotating rod 319, bevel gear 328, second pulley 325, and gear 321 to rotate synchronously. Among them, the bevel gear 328 drives the first pulley 318 to rotate, which in turn drives the running rod 316 and the threaded rod 312 to rotate, causing the two threaded plates 313 to move in opposite directions along the threaded rod 312, thereby pushing the protective plate 314 to shield and protect the camera body 2.

[0033] At the same time, gear 321 drives another rotating rod 319 to rotate in the opposite direction, causing the two rotating rods 319 to rotate in opposite directions, thereby driving the guide plate 322 to swing towards the bottom of the mounting base 1; the guide plate 322 simultaneously drives the mounting rod 323, positioning plate 324 and buffer air cushion 32 to move, causing the buffer air cushion 32 to unfold and cover the outer surface of the protective plate 314, forming a double-layer protective structure, effectively suppressing the shaking of the camera body 2 in special environments, significantly improving its protective performance, and thus completing the function of protecting the camera body 2. When the camera body 2 is protected, it can use the space in front of the two buffer air cushions 32 and the protective plate 314 to continuously shoot, thereby avoiding the situation of the camera body 2 being blocked when shooting. It can also use the space in front of the camera body 2 to dissipate heat normally (because its two buffer air cushions 32 and the protective plate 314 are semi-circularly set, the front side has a cavity structure when the protection is closed, which allows the camera body 2 to shoot normally and dissipate heat through air circulation).

[0034] When it is necessary to store the cushioning air cushion 32, the motor 320 is reversed and the above structure is driven to run in the opposite direction, so that the cushioning air cushion 32 is first stored on the left and right sides of the top of the mounting plate 31, thereby moving the cushioning air cushion 32 away from the protective plate 314. After the cushioning air cushion 32 is stored, the two protective plates 314 gradually move away from the camera body 2.

[0035] In addition, the bevel gear 328 drives the second pulley 325 to rotate, the second pulley 325 drives the long rod 34 to rotate, and the long rod 34 drives the running plate 36 to move synchronously; the running plate 36 pushes the running rod 38 to move back and forth, thereby driving the top plate 37 to move up and down back and forth, repeatedly squeezing the inflatable ball 39; the inflatable ball 39 continuously supplies air to the buffer air cushion 32 through the hose 310, so that it inflates synchronously during the deployment process, ensuring that the buffer air cushion 32 is fully expanded and fits the protective surface, so as to quickly and reliably achieve buffer protection.

[0036] Furthermore, the linked inflation structure of the protective component 3, consisting of the top plate 37, the running rod 38, and the inflatable ball 39, integrates mechanical motion and pneumatic function, realizing the power supply inflation function. When the protective function is activated and the protective plate 314 begins to unfold, the transmission mechanism synchronously drives the top plate 37 to reciprocate. The top plate 37 applies reciprocating compression to the inflatable ball 39 through the running rod 38, thereby continuously pumping air into the buffer air cushion 32 through the hose 310. This not only reduces the failure rate but also truly achieves the function of "inflating as soon as it unfolds".

[0037] The cushioning air pad 32 can inflate within seconds, quickly forming a full and uniform buffer layer to provide immediate protection for the camera body 2. In extreme conditions, such as when the equipment is overturned by a sudden strong wind, the bracket becomes loose and the camera falls unexpectedly, or when it is subjected to violent displacement caused by an explosive shock wave, the inflated cushioning air pad 32 can effectively absorb and dissipate most of the vertical and lateral impact energy. Meanwhile, the protective plate 314 bears and disperses the remaining concentrated impact stress, preventing local deformation or shell breakage. The two work together to form a composite protective function of energy absorption and impact resistance, significantly reducing the risk of critical damage such as lens breakage, circuit board breakage, and seal failure.

[0038] More importantly, it takes into account both daily use and emergency protection needs: in non-dangerous situations, the buffer air cushion 32 is in a retracted state, which does not affect the heat dissipation and field of view of the device; once an abnormal environment is detected, the double-layer protection is activated without human intervention. As a result, it not only greatly improves the survivability, availability and service life of the camera body 2 in harsh and high-risk scenarios such as petrochemical, mining and military industries, but also provides a solid guarantee for the continuous and stable operation of remote monitoring and is easy to use.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
