Description

Technical Field

[0001] This utility model relates to the field of mining camera technology, specifically a mining encapsulation and intrinsically safe image processing camera with a display screen and battery. Background Technology

[0002] In underground mining environments such as coal mines, in order to ensure production safety and operational efficiency, it is necessary to use video equipment to monitor underground roadways, equipment operating status, and working environment in real time.

[0003] Underground coal mine operations generate a large amount of suspended particulate matter such as coal dust and rock dust, which makes it easy for dust to adhere to the surface of camera lenses, causing blurred images and loss of details, seriously affecting the accuracy of monitoring data.

[0004] In existing solutions, most cameras use oscillating cleaning brushes to remove lens dust. However, the cleaning brush itself is directly exposed to a highly polluted environment, and its bristles can become contaminated with dust or moisture. This not only fails to thoroughly remove contaminants from the lens surface but may also create secondary pollution during the cleaning process. More importantly, the oscillation of the cleaning brush relative to the lens causes dust particles to slide on the lens surface, resulting in scratches and damage, and shortening the lens's lifespan.

[0005] Meanwhile, most equipment relies on external cables for power supply. These cables are susceptible to mechanical impact, wear, or compression damage in the complex underground environment. Once a line fails, monitoring will be interrupted. Furthermore, the wiring is cumbersome and cannot meet the needs of scenarios such as mobile inspections and monitoring of temporary work sites.

[0006] Furthermore, existing mining cameras generally do not integrate real-time display functionality. The captured images or videos must be exported to a ground terminal via a data cable before they can be viewed. This prevents operators from judging the shooting effect on-site underground, often resulting in invalid shooting due to angle deviations or improper parameter settings, requiring repeated operations and significantly reducing work efficiency.

[0007] To address this, a mine-use encapsulation and intrinsically safe image processing camera with a display screen and battery is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a mining-grade encapsulation and intrinsically safe image processing camera with a display screen and battery, in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a mining-grade encapsulation and intrinsically safe image processing camera with a display screen and a battery, comprising a camera housing, wherein housings are symmetrically installed on both sides of the front end of the camera housing, and a film winding cylinder is rotatably connected inside each of the two housings, and a transparent protective film is wound between the two film winding cylinders;

[0010] One of the housings is equipped with a drive motor for moving the protective film, and the bottom of the other housing is equipped with a spring box for tightening the protective film.

[0011] Preferably, a rotating rod is rotatably connected to the bottom inner side of each of the two housings, and a cover is installed on the top of each of the two housings. A limiting rod is installed on the lower surface of the cover, and both the limiting rod and the rotating rod are inserted into the inside of the film roll.

[0012] Preferably, a limiting protrusion is installed on the outer side of the rotating rod, and a limiting groove is formed on the inner side of the film winding tube, wherein the limiting groove is adapted to the limiting protrusion.

[0013] Preferably, the output shaft of the drive motor is connected to the bottom end of a rotating rod via gear transmission, and the mainspring inside the mainspring barrel is connected to the bottom end of another rotating rod.

[0014] Preferably, the front surface of the housing has a through groove to facilitate the movement of the protective film.

[0015] Preferably, a display screen and buttons are installed on one side of the camera housing.

[0016] Preferably, the camera housing contains a camera module, a fill light, a motherboard, and a potted power supply.

[0017] Preferably, the camera housing and the front surface of the housing are both equipped with guide rollers for guiding and limiting the protective film.

[0018] Preferably, a limiting plate is installed on the front surface of the camera housing, and the limiting plate has a limiting groove for the protective film to pass through and a through hole for the camera to capture images.

[0019] Compared with existing technologies, the advantages of this invention are as follows: By combining the transparent protective film with the replacement mechanism, the problems of secondary contamination and lens scratches caused by traditional cleaning brushes are completely solved. The protective film, under the dual constraint of the guide roller and the upper limit groove of the limiting plate, always accurately covers the lens area. Combined with the continuous tension of the spring box, this ensures the film is flat and wrinkle-free, with stable light transmittance. The integrated display screen and buttons can display the captured images, equipment status, and parameters in real time. Operators can judge the shooting effect on-site without exporting data, reducing unnecessary work. The built-in battery eliminates reliance on external cables, avoiding monitoring interruptions caused by line wear and breakage, and improving the reliability and safety of the equipment in scenarios such as mobile inspections and temporary work sites.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-7 This utility model provides a technical solution: the camera housing 1 serves as the main support structure of the device, with two housings 4 symmetrically fixed on both sides of its front end. Inside the housings 4, a film roll 11 is rotatably supported by a rotating rod 15 and a limiting rod 9 on the lower surface of the cover 8. A limiting groove 14 on the inner side of the film roll 11 is adapted to a limiting protrusion 16 on the outer side of the rotating rod 15, ensuring that the film roll 11 rotates synchronously with the rotating rod 15. A transparent protective film 6 is wound between the two film rolls 11. The protective film 6 extends through a through groove 12 on the front surface of the housing 4 and is guided and limited by the guide rollers 5 on the front surface of the camera housing 1 and the housing 4, forming a protective cover for the front lens area of ​​the camera.

[0030] The limiting grooves 22 are formed on both sides of the limiting plate 21. The width of the grooves is adapted to the thickness of the protective film 6. After the protective film 6 extends from the through grooves 12 of the two housings 4, it needs to pass through the limiting grooves 22 before covering the front of the lens. The limiting grooves 22 form a lateral constraint on the protective film 6 through the inner walls on both sides, preventing it from shifting due to vibration or external impact during movement or tensioning. This ensures that the protective film 6 always accurately covers the lens area, does not obstruct the shooting field of view, and can also effectively reduce the occurrence of dust entering behind the film.

[0031] The through hole 23 is located in the middle of the limiting plate 21. Its diameter is slightly larger than the outer diameter of the camera lens, providing an unobstructed shooting channel for the camera module 17 and ensuring that light enters the lens normally.

[0032] One of the housings 4 has a drive motor 7 fixedly installed on one side, and its output shaft is connected to the bottom end of the corresponding rotating rod 15 through gear transmission. This motor drives the film roll 11 to rotate so as to move and replace the protective film 6. The bottom of the other housing 4 has a spring box 13 installed. One end of the spring inside the spring box 13 is connected to the bottom end of the rotating rod 15 on the same side, and the other end is fixed to the inner wall of the spring box 13. The elastic deformation of the spring generates a continuous torque, so that the protective film 6 is always kept taut and avoids loosening that would affect the protective effect.

[0033] A display screen 2 and buttons 3 are integrated on one side of the camera housing 1. The display screen 2 is used to display captured images and equipment parameters in real time, and the buttons 3 are used for operating the equipment and adjusting parameters. Inside the housing 1, there is a camera module 17, a fill light 18, a motherboard 19, and a potted power supply 20. The camera module 17 is responsible for image acquisition, the fill light 18 provides supplementary lighting in low-light environments, the motherboard 19 implements image processing and control logic, and the potted power supply 20 adopts a potted and intrinsically safe design to ensure safe power supply in flammable and explosive environments such as coal mines.

[0034] When the image clarity is affected by contamination such as mineral dust and water mist on the surface of the protective film 6, the drive motor 7 is started. The drive motor 7 drives one side of the film winding drum 11 to rotate, and winds the contaminated protective film 6 onto the film winding drum 11 on that side. At the same time, the other side of the film winding drum 11 releases a new protective film 6 under the torque of the spring box 13, thus completing the automatic replacement of the protective film 6.

[0035] This embodiment, through the above structural design, achieves automatic protection and cleaning of the camera lens in a mining environment. Combined with the potting and intrinsically safe power supply design, it not only meets the safety requirements of dangerous environments such as coal mines, but also improves the portability and real-time operation capability of the equipment through the integration of the display screen and battery.

[0036] It should be noted that the specific models of the drive motor 7, the spring box 13 and other components of this utility model can be selected according to the actual power requirements, and the protective film 6 can be made of wear-resistant and anti-static transparent material to adapt to the harsh environment in the mine.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
