Description

Technical Field

[0001] This utility model relates to a pan-tilt mobile explosion-proof camera device with circumferential supplementary lighting function, belonging to the field of explosion-proof camera technology. Background Technology

[0002] According to section 5.2.11 of the "Safety Specifications for Special Operations in Hazardous Chemical Enterprises" (GB30871-2022), all special-grade hot work operations should be video-recorded throughout the entire process, and the recording equipment used at the work site should be explosion-proof. Especially in industries such as petroleum, chemical, metallurgy, and municipal engineering, when performing maintenance and repair work in confined spaces, such as furnaces, towers, tanks, warehouses, pools, tank trucks, pipelines, and flues, the enclosed working environment often results in dim lighting. Even with external lighting, it only covers the work area. According to relevant regulatory requirements, any maintenance or repair work requires the presence of safety supervisors. However, for confined spaces, supervisors typically monitor from outside the confined space, using the following methods to confirm the working conditions and safety status of personnel within the confined space.

[0003] First, supervisors can check the confined space entrance at different times or enter the confined space to confirm the safety status of the workers. A more rudimentary method is to confirm the safety of the workers inside the confined space by tapping on the pipe walls and shouting.

[0004] Secondly, cameras are installed in the confined space and connected to the host outside the confined space via wired or wireless means. Supervisors observe the operation process in the confined space through the screen of the host. Because the confined space is a closed environment, the light is dim, which leads to relatively blurry video surveillance images and makes it difficult to detect dangers in time.

[0005] Third, while walkie-talkies can be used to confirm the safety of operations inside confined spaces, the materials in confined spaces are generally metal, which can interfere with the transmission efficiency of walkie-talkies and create potential dangers due to untimely information transmission.

[0006] In conclusion, all of the above methods pose potential dangers, therefore a device that can overcome these shortcomings is urgently needed. Utility Model Content

[0007] This invention aims to solve the problem that existing video surveillance equipment suffers from blurred video images due to spatial and lighting factors in the working environment, making it impossible to promptly confirm the safety of workers. Therefore, it provides a pan-tilt mobile explosion-proof camera device with circumferential supplementary lighting function.

[0019] Furthermore, the upper terminal block is fixed in the lower housing by a number of first copper pillars, and the lower terminal block is fixed in the lower housing by a number of second copper pillars.

[0020] Furthermore, there is a threaded connection between the transparent cover and the shell.

[0021] Furthermore, the transparent cover has a first annular outer edge at the opening end, and the upper shell has a second annular outer edge at the top. The first annular outer edge passes through the upper shell and overlaps below the second annular outer edge. A threaded ring is threaded through the upper part of the upper shell to limit the position of the transparent cover.

[0022] Furthermore, the explosion-proof switches, cable entry connectors, and clip connectors are arranged alternately with multiple lighting components.

[0037] A pan-tilt-zoom (PTZ) mobile explosion-proof camera device with circumferential lighting includes a transparent cover 1, a housing, a camera 2, an illumination assembly 6, an explosion-proof switch 15, a cable entry connector 28, and a clip connector 29. The camera 2 is a 360-degree rotating camera, mounted inside the housing with its lens protruding above it. The transparent cover 1 covers the camera 2 and is sealed to the top of the housing.

[0038] The lighting components 6 are in multiple sets and are evenly distributed circumferentially in the lower part of the housing.

[0039] The explosion-proof switch 15, the cable inlet connector 28, and the clip connector 29 are respectively arranged in the lower part of the housing.

[0040] An upper terminal block 13 and a lower terminal block 16, which are electrically connected, are installed inside the housing below the camera 2. The lighting component 6, the explosion-proof switch 15, the cable entry connector 28, and the clip connector 29 are electrically connected to the lower terminal block and are all sealed to the housing.

[0041] The base of the camera 2 is mounted on the upper wiring board 13, and several Hall effect tubes 9 are evenly distributed around the upper wiring board 13 on the outside of the camera 2. The several Hall effect tubes 9 are arranged in a one-to-one correspondence with several lighting components 6. A magnet 7 is installed on the camera 2, and the magnet 7 cooperates with the Hall effect tubes 9 below it to control the opening and closing of the corresponding lighting components 6.

[0042] The base and lens of the camera 2 are both components of the camera 2. The main body of the camera 2 can rotate 360 ​​degrees relative to the base. The lens is located on the upper part of the main body of the camera 2. These are all existing technologies and will not be described in detail here. The camera 2 has the function of recording and storing video. The camera 2 is equipped with a memory card, which can record video and store it as data.

[0043] The magnet 7 is positioned above the Hall effect tube 9. The Hall effect tube 9 is preferably soldered onto the upper terminal block 13.

[0044] A sealing ring is provided between the explosion-proof switch 15, the cable inlet connector 28, and the card holder connector 29 and the housing.

When the magnet 7 moves away from the aforementioned corresponding lighting component 6, the lighting component 6 is turned off. In this way, when the camera 2 rotates to any circumferential position, the nearby lighting component 6 will be turned on and the lighting component 6 at the far position will be turned off.

[0054] This utility model discloses a pan-tilt mobile explosion-proof camera device with circumferential supplementary lighting function. Through a 360-degree rotating camera, it achieves all-round real-time video monitoring, effectively solving the problem of untimely information transmission caused by intercom. It adds an independent circumferential supplementary lighting facility, namely several lighting components 6 arranged circumferentially. As the camera 2 rotates, it drives the magnet 7 to rotate, realizing the opening and closing control of the lighting components 6 in the direction recorded by the camera 2, thereby achieving supplementary lighting without blind spots.

[0055] This utility model discloses a pan-tilt mobile explosion-proof camera device with circumferential supplementary lighting function. The supplementary lighting device is activated by a magnetic switch, which eliminates contact friction, ensuring the sealing integrity of the device and greatly increasing the product's service life. Moreover, it is very easy to disassemble.

[0056] This utility model discloses a pan-tilt mobile explosion-proof camera device with circumferential supplementary lighting function. It has waterproof, dustproof and explosion-proof functions. By sealing the lighting component 6, explosion-proof switch 15, cable inlet connector 28 and card holder connector 29 to the housing, and sealing the housing and transparent cover 1, sparks generated inside the supplementary lighting housing cannot be conducted out, thereby ensuring the safety of application in dangerous places. At the same time, the waterproof and dustproof performance is enhanced, avoiding the accumulation of harmful gases and dust.

[0057] The lighting assembly 6 includes a lighting cylinder cover 18, a lighting glass 21, a lighting condenser cup 22, a light-emitting panel 23, and a condenser cup support cover 24. The light-emitting panel 23 is fixedly mounted on the condenser cup support cover 24, which is inserted inside the lighting cylinder cover 18. The small-diameter end of the lighting condenser cup 22 covers the light-emitting panel 23 and is supported by the condenser cup support cover 24. The lighting glass 21 is positioned on the large-diameter end of the lighting condenser cup 22 and sandwiched between the lighting cylinder cover 18 and the condenser cup support cover 24. A glass retaining ring 19 is provided between the condenser cup support cover 24 and the lighting glass 21, and a sponge pad 20 is provided between the glass retaining ring 19 and the lighting condenser cup 22. Several light-emitting panels 23 are electrically connected to a lower wiring board. With this design, the lighting cylinder cover 18 is threaded through the lower part of the housing, and a sealing ring is provided between the lighting cylinder cover 18 and the housing. The lighting cylinder cover 18 has a ring-shaped structure with open ends at both ends. One end has a ring-shaped flange for axial positioning of the lighting glass 21. The condenser cup cover 24 has a cylindrical structure with its open end facing the lighting glass 21. The lighting glass 21 serves to protect the light-emitting panel 23 and the lighting condenser cup 22.

[0058] The housing comprises an upper housing 4 and a lower housing 17 connected by threads. This design, by separating the housing, facilitates the installation and maintenance of the camera 2 and other internal structural components.

[0059] A handle is installed on the outside of the casing. This design facilitates carrying and adds a hand-carrying function, while also making the device lightweight.

[0060] Magnet 7 is fixed to camera 2 by mounting bracket 5. In this design, mounting bracket 5 is a bent structure to adapt to the external contour of camera 2. The upper end of mounting bracket 5 is mounted to the body of camera 2 by screws, and magnet 7 is mounted to the lower end of mounting bracket 5 by screws.

[0061] The center of magnet 7 and the center of lens of camera 2 are located in the same vertical plane. This design ensures that the position where camera 2 captures video is the same as the position where lighting component 6 provides illumination.

[0062] The upper terminal block 13 is fixedly mounted inside the lower housing 17 by a number of first copper posts 12, and the lower terminal block 16 is fixedly mounted inside the lower housing 17 by a number of second copper posts 27. With this design, both the first copper posts 12 and the second copper posts 27 are threaded into the bottom end of the lower housing 17. The upper terminal block 13 is fixed to the M4*50 first copper posts 12 by M4 screws, and the lower terminal block 16 is fixed to the M4*10 second copper posts 27 by M4 screws.

[0063] The transparent cover 1 and the upper housing 4 can be directly connected by threads for easy assembly and disassembly. Alternatively, a first annular outer edge can be machined at the open end of the transparent cover 1, and a second annular outer edge can be machined at the top of the upper housing 4. The first annular outer edge passes through the upper housing 4 and overlaps below the second annular outer edge. A threaded ring 3 is threaded through the upper part of the upper housing 4, which limits the movement of the transparent cover 1. In this design, the outer surface of the threaded ring 3 is threaded and connected to the inner wall of the upper housing 4 below the transparent cover 1, thereby pressing the transparent cover 1 and limiting its vertical displacement.

[0064] The explosion-proof switch 15, cable entry connector 28, and clip connector 29 are arranged alternately with multiple sets of lighting components 6. This design ensures that the circumferential distribution of multiple sets of lighting components 6 is not affected, while making more reasonable use of the circumferential space in the lower part of the housing for a more rational layout.

[0065] Installation process:

[0066] First, the transparent cover 1 is fixed to the upper shell 4. The second annular outer edge of the upper shell 4 is machined with a glue storage groove on the side facing the first annular outer edge. The glue storage groove is filled with sealant. Then, the transparent cover 1 and the upper shell 4 are pressed together by the screw ring 3.

[0067] Install magnet 7 onto camera 2;

[0068] Fix the lower terminal block 16 to the second copper post 27 with screws, then install the second copper post 27 to the bottom of the lower housing 17, and then install the explosion-proof switch 15, cable inlet connector 28 and card holder connector 29 in sequence around the lower housing 17.

[0069] After assembling the lighting components 6, install them onto the circumference of the lower housing 17.

[0070] Fix the upper wiring board 13 and the base of the camera 2 to the first copper pillar 12 with screws, then install the first copper pillar 12 to the bottom of the lower housing 17, and finally thread the upper housing 4 and the lower housing 17 together. Set a sealing ring at the connection between the upper housing 4 and the lower housing 17.

[0071] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
