Description
Technical Field
[0001] The present invention relates to the technical field of well and mine monitoring, and particularly to an intrinsically safe image processing camera for mines. Background Art
[0002] An intrinsically safe camera is a special safety device designed specifically for flammable and explosive hazardous environments. Its core feature is the adoption of intrinsic safety technology to ensure that the device will not generate sparks, heat, or electrical energy sufficient to ignite the surrounding explosive gases or dust during normal use or in a fault state.
[0003] However, during the installation process of existing intrinsically safe cameras, multiple fixing screws are generally used for fixation. This method not only makes the installation process of the device relatively complex but also brings a series of potential problems. Since a gasket is usually provided inside the camera to ensure its waterproof and dustproof performance, when using screws for local fastening, the gasket will be subjected to uneven extrusion pressure. This local sealing method causes some parts of the gasket to bear a large pressure, while other parts may not be fully compressed, resulting in uneven stress on the gasket. Over time, this uneven stress will accelerate the aging process of the gasket, thereby affecting the sealing performance and service life of the camera. In addition, the installation method using screws also increases the difficulty of camera maintenance. When maintenance or repair of the camera is required, disassembling and reinstalling multiple screws not only takes time and effort but also easily causes damage to the camera or the gasket during the operation. This complex installation method not only reduces the maintenance efficiency but also increases the complexity and cost of repair. Therefore, the existing installation method of intrinsically safe cameras urgently needs to be improved to simplify the installation process, improve the sealing performance, and reduce the maintenance difficulty.
[0004] In addition, during the operation of existing downhole operation cameras, the dust concentration in the downhole environment is high, and these dusts are extremely easy to suspend in the air. When the camera performs monitoring tasks, a large amount of dust and impurities will quickly adhere to the surface of its lens, which greatly affects the clarity of the image and the accuracy of data collection. To address this problem, traditional cleaning methods mainly rely on compressed air blowing or mechanical scraping. However, both of these methods have obvious limitations: Compressed air blowing requires an external air source and may disturb the dust in the air during the operation, instead exacerbating the pollution of the lens surface; while the mechanical scraper can remove some dust but is powerless against stubborn particles adhering to the lens. Therefore, the existing cleaning methods are single and ineffective, and it is difficult to effectively deal with the accumulation problem of stubborn dust in downhole operations.
[0005] Therefore, an intrinsically safe image processing camera for mines is proposed to solve the above problems. Summary of the Invention

[0020] Compared with the prior art, the present invention provides a mine intrinsically safe image processing camera, which has the following beneficial effects:
[0021] 1. This solution can reduce the shaking caused by the reverse action of the spring deformation through the V-shaped elastic plate.

By the sliding of the first push plate, the second clamping plate can be driven to engage with the first clamping plate, the first clamping frame and the second clamping frame, so that the light-shielding cover can be quickly installed on the box body. When the camera fails, the maintenance personnel can quickly locate and solve the problem, enabling the maintenance personnel to easily disassemble and install the camera without complex tools or skills, and can also quickly disassemble and replace it, reducing the downtime and improving the maintenance efficiency.
[0024] 4. In this solution, the second clamping plate, the first clamping plate and the auxiliary clamping plate can quickly engage and seal the first clamping frame and the second clamping frame. Compared with the local fixation generated by traditional bolt fixation, this solution uses distributed extrusion fixation, which can make the sealing gasket in the first clamping frame and the second clamping frame be evenly extruded, reducing the damage of the sealing gasket caused by local extrusion, and thus increasing the service life of the sealing gasket.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0041] In the embodiment, refer to the attached Figure 1 to the attached Figure 10 .
[0042] A intrinsically safe image processing camera for mining use, including a box body 1, a light-shielding cover 11 is arranged above the box body 1, first brackets 13 are installed on both sides of the box body 1, a probe dome glass 12 is installed in the middle of the box body 1, a second bracket 14 is arranged above the first bracket 13. The intrinsically safe image processing camera for mining use further includes a dynamic damping mechanism 2, an electrostatic composite dust removal mechanism 3 and a modular quick-release mechanism 4;
[0043] The dynamic damping mechanism 2 is arranged in the first bracket 13, and the dynamic damping mechanism 2 is used for reducing vibration when the first bracket 13 is fixed;
[0044] The electrostatic composite dust removal mechanism 3 is arranged on the outer surface of the probe dome glass 12, and the electrostatic composite dust removal mechanism 3 is used for removing static electricity on the surface of the probe dome glass 12;
[0045] The modular quick-release mechanism 4 is arranged at the bottom of the light-shielding cover 11, and the modular quick-release mechanism 4 is used for the quick modular installation and disassembly of the box body 1 and the light-shielding cover 11;
[0046] Specifically, referring to the appendix Figure 3 and the appendix Figure 4 As shown in the figure, a buffer groove 21 is opened in the first bracket 13, the second bracket 14 is slidably connected in the buffer groove 21 opened in the first bracket 13, a V-shaped elastic plate 22 is installed near the bottom of the second bracket 14 in the buffer groove 21, one end of the V-shaped elastic plate 22 away from the buffer groove 21 is provided with a rocker 23, a fixing block 25 is rotatably connected in the middle of the rocker 23, and one end of the fixing block 25 away from the rocker 23 is fixedly connected to the outer surface of the first bracket 13;
[0047] Among them, the V-shaped elastic plate 22 is made of a high-toughness metal material, has good corrosion resistance, and can withstand repeated tensile and compressive deformations without being easily broken;
[0048] When the second bracket 14 is subjected to external vibration, at this time, due to the action of gravity, the bottom of the second bracket 14 will exert pressure on the V-shaped elastic plate 22, causing the V-shaped elastic plate 22 to deform. Since one end of the V-shaped elastic plate 22 is rotatably connected in the buffer groove 21 and the other end slides in the buffer groove 21, when the V-shaped elastic plate 22 is compressed, it will drive the V-shaped elastic plate 22 to move to the left. At this time, the movement of the V-shaped elastic plate 22 to the left will drive the rocker 23 to start moving. Through the elastic action of the V-shaped elastic plate 22 itself, it can deform when the camera is subjected to external impact or vibration, thereby absorbing and dispersing energy, so as to reduce image jitter or blur caused by vibration and improve the stability and image quality of the camera.
[0049] Further, auxiliary grooves 24 are provided at both ends of the rocker 23, and one end of the V-shaped spring plate 22 away from the buffer groove 21 is movably connected in the auxiliary groove 24, and a damping rod 26 is movably connected in the auxiliary groove 24 at one end of the rocker 23 away from the V-shaped spring plate 22, and the damping rod 26 is slidably connected in the first bracket 13, and rubber plates 27 are installed on both sides of the second bracket 14, and the rubber plates 27 are made of flexible rubber material;
[0050] The deformation of the V-shaped spring plate 22 can drive the seesaw 23 to rotate on the fixed block 25. Through the principle of leverage, the deformation of the V-shaped spring plate 22 can push the seesaw 23 to drive the damping rod 26 to slide in the first bracket 13 in the opposite direction, wherein the auxiliary groove 24 is provided to solve the distance change caused by the displacement in the lever process. The damping rod 26 can be squeezed toward the side of the rubber plate 27 installed in the second bracket 14 through the reverse movement of the damping rod 26. Since the rubber plate 27 is made of flexible rubber material, the rubber plate 27 can be squeezed by the damping rod 26 to produce a damping effect on the vibration of the second bracket 14. Compared with the traditional method of directly installing a buffer spring at the bottom of the bracket for vibration reduction, the present solution can reduce the shaking caused by the reverse effect of the deformation of the spring through the V-shaped spring plate 22. The damping rod 26 performs reverse damping extrusion on the second bracket 14 under the action of the deformation of the V-shaped spring plate 22, thereby increasing the damping force of the bracket, especially the external disturbance caused by a series of mechanical vibrations such as blasting and vibration generated during mine operations, so that the camera can still maintain a stable shooting posture in a complex environment.
[0051] Specifically, the servo drive motor 31 is installed at the bottom of the box body 1, and a wiper frame 32 is fixedly installed on the drive shaft of the servo drive motor 31. The wiper frame 32 is rotatably connected to the box body 1 at one end away from the servo drive motor 31. A negative electrode vibration brush 34 is slidably installed in the middle of the arc surface of the wiper frame 32. Positive electrode dust collecting plates 33 are arranged on both sides of the negative electrode vibration brush 34, and the positive electrode dust collecting plates 33 are installed on the wiper frame 32.
[0052] The positive dust collecting plate 33 is electrically connected to the positive pole of the power supply, and the negative vibration brush 34 is connected to the negative pole of the power supply through a wire. The negative charge generated by the negative vibration brush 34 can transfer the charge to the dust on the surface of the probe ball cover glass 12, and the dust with negative charge will quickly adhere to the positive dust collecting plate 33 with positive charge, thereby reducing the dust emission effect during the dust processing process.
[0053] Further, an oscillation spring 35 is symmetrically arranged in the wiper frame 32, one end of the oscillation spring 35 is fixedly connected to the negative vibration brush 34, and the other end of the oscillation spring 35 is fixedly connected to the wiper frame 32. A micro motor is installed in the middle of the wiper frame 32, and an offset collision block 36 is installed on the micro motor drive shaft. The offset collision block 36 is eccentrically installed on the micro motor drive shaft;
[0054] Among them, a flexible cleaning material is provided on the contact surface between the negative vibration brush 34 and the probe dome glass 12 to prevent damage to the surface of the probe dome glass 12 when the negative vibration brush 34 oscillates.
[0055] Driven by the micro motor, the offset collision block 36 can achieve eccentric rotation. Under the elastic support and reset action of the oscillation spring 35, the eccentric rotation of the offset collision block 36 can be converted into a periodic driving force for the negative vibration brush 34, thereby causing the negative vibration brush 34 to generate reciprocating vibration. Through this reciprocating vibration, on the one hand, it can enhance the dust cleaning ability of the surface of the probe dome glass 12, and effectively shake off the dust adhering to the surface of the probe dome glass 12 through mechanical vibration; on the other hand, during the vibration process, the charges in the negative vibration brush 34 will collide frequently with the dust, which not only helps to separate the dust from the surface of the probe dome glass 12, but also increases the uniformity of the dust charging. When the surface of the component probe dome glass 12 passes through the oscillating cleaning of the component negative vibration brush 34, the dust removed will be charged during the collision process. At this time, those dusts with a certain negative charge will, under the action of the electric field force, quickly move towards the surface of the component positive dust collecting plate 33 with a positive charge and will ultimately be adsorbed on the component positive dust collecting plate 33. This process realizes the effective collection and separation of dust, improving the cleaning efficiency and effect.
[0056] In contrast, compressed air blowing requires relying on an external air source, and may disturb the dust in the air during operation, instead exacerbating the pollution of the lens surface; while the mechanical scraper can remove some dust, but is powerless against the stubborn particles adhering to the lens; through the design of this solution, not only the dust generation during the cleaning process is reduced, but also the cleaning of the surface of the probe dome glass 12 can be increased through the oscillation of the negative vibration brush 34.
[0057] Specifically, referring to Figure 5 and Figure 6 , the first card frame 41 is installed on the upper surface of the box body 1, the second card frame 42 is installed at the bottom of the light shielding cover 11. Sealing gasket grooves are provided in both the first card frame 41 and the second card frame 42, and sealing gaskets are installed in the sealing gasket grooves. Positioning columns are uniformly and fixedly installed on the outer side of the first card frame 41 near the sealing gasket groove, and positioning grooves are fixedly installed on the outer side of the second card frame 42 near the sealing gasket groove. The positioning columns and the positioning grooves are used for the quick positioning of the light shielding cover 11 and the box body 1, and the sizes of the positioning columns are adapted to the sizes of the positioning grooves;
[0058] The light shielding cover 11 and the box body 1 can be quickly positioned and installed through the positioning grooves and the positioning columns.
[0059] Further, an adjusting cylinder 43 is provided in the middle of the upper surface of the light-shielding cover 11. A ratchet wheel 44 is fixedly connected to the inner surface of the middle part of the adjusting cylinder 43. A ratchet pawl 45 is engaged with the tooth surface of the ratchet wheel 44. The bottom of the ratchet pawl 45 is rotatably connected to the light-shielding cover 11. A first torsion spring 46 is sleeved on the outer surface of the bottom of the ratchet pawl 45. One end of the first torsion spring 46 is fixedly connected to the ratchet pawl 45, and the other end of the first torsion spring 46 is fixedly connected to the light-shielding cover 11. A push rod 47 is fixedly connected to the outer surface of the bottom of the ratchet pawl 45. The end of the push rod 47 away from the first torsion spring 46 is arranged on the upper surface of the adjusting cylinder 43;
[0060] Wherein, by rotating the adjusting cylinder 43, the elliptical plate 51 can be driven to rotate. Compared with the traditional scheme, after rotating the adjusting cylinder 43 in this scheme, under the elastic action of the first torsion spring 46, the ratchet wheel 44 and the ratchet pawl 45 can be engaged, so that the ratchet wheel 44 can be locked on the light-shielding cover 11.
[0061] Further, as shown in the attached Figure 8 As shown, the middle part of the elliptical plate 51 is fixedly connected to the middle part of the ratchet wheel 44 through a transmission shaft. A first arc-shaped groove 52 and a second arc-shaped groove 57 are symmetrically formed in the elliptical plate 51 respectively. Bearings are arranged in the middle parts of the first arc-shaped groove 52 and the second arc-shaped groove 57. A first push plate 53 is installed on the bearing in the middle part of the first arc-shaped groove 52;
[0062] Furthermore, the outer surface of the first push plate 53 is slidably connected to the bottom of the light-shielding cover 11 through a support block. A second clamping plate 55 and a first clamping plate 54 are installed at the end of the first push plate 53 away from the first arc-shaped groove 52. The first clamping plate 54 is rotatably connected to the second clamping plate 55. A second torsion spring 56 is installed on the second clamping plate 55 and the first clamping plate 54. Pressing grooves are formed on both the second clamping plate 55 and the first clamping plate 54, and the pressing grooves are used for quick clamping of the first clamping frame 41 and the second clamping frame 42; A second push plate 58 is installed on the bearing of the second arc-shaped groove 57. The second push plate 58 is slidably connected to the light-shielding cover 11 through a support block. An auxiliary clamping plate 59 is fixedly installed at the end of the second push plate 58 away from the second arc-shaped groove 57. A pressing groove is also formed on the auxiliary clamping plate 59, and its function is the same as that of the above-mentioned pressing groove;
[0063] Wherein, by rotating the elliptical plate 51, the first push plate 53 and the second push plate 58 can be driven to move different distances. By the movement of the first push plate 53 and the second push plate 58, the second clamping plate 55, the first clamping plate 54 and the auxiliary clamping plate 59 are further driven to clamp the first clamping frame 41 and the second clamping frame 42.
[0064] In this solution, by adjusting the adjusting cylinder 43, the elliptical plate 51 can be driven to rotate synchronously. Then, through the mutual extrusion between the first arc-shaped groove 52 and the first push plate 53, the first push plate 53 can be driven to slide at the bottom of the light-shielding cover 11. By the sliding of the first push plate 53, the second clamping plate 55, the first clamping plate 54 can be driven to engage with the first clamping frame 41 and the second clamping frame 42, so that the light-shielding cover 11 can be quickly installed on the box body 1. When the camera fails, maintenance personnel can quickly locate and solve the problem, enabling the maintenance personnel to easily disassemble and install the camera without complex tools or skills, and can also quickly disassemble and replace it, reducing the downtime and improving the maintenance efficiency. Moreover, in this solution, through the second clamping plate 55, the first clamping plate 54 and the auxiliary clamping plate 59, the first clamping frame 41 and the second clamping frame 42 can be quickly clamped and sealed. Compared with the local fixation generated by traditional bolt fixation, this solution adopts distributed extrusion fixation, which can make the sealing gaskets in the first clamping frame 41 and the second clamping frame 42 be evenly extruded, reducing the damage to the sealing gaskets caused by local extrusion, thereby increasing the service life of the sealing gaskets.
[0065] Based on the above embodiments, the specific implementation process of this solution is as follows.
[0066] The present invention provides a dynamic damping mechanism 2. When in use, as Figure 4 shown, due to the complexity of underground operations, blasting is a common operation method in mining engineering. However, the vibration waves generated by blasting activities not only have an important impact on the mining engineering itself, but may also cause vibrations to the surrounding environment. At the same time, common vibration tools in coal mines, such as piston-type hammering tools like rock drifters, pneumatic hammer riveters, etc., fixed rotary tools like grinders, electric saws, etc., and handheld rotary tools like pneumatic drills, electric coal drills, etc., will all generate vibrations during the working process. Since the camera device of this solution is installed in the mine for monitoring operations, the above vibrations generated underground will be directly transmitted to the camera device. When these vibration devices are first transmitted to the second bracket 14, the second bracket 14 will generate an amplitude. The second bracket 14 with a certain amplitude will slide in the buffer groove 21 opened in the first bracket 13. Due to the gravity, the second bracket 14 will start to continuously squeeze the V-shaped elastic plate 22, causing the V-shaped elastic plate 22 to deform. Since one end of the V-shaped elastic plate 22 is rotatably connected in the buffer groove 21 and the other end slides in the buffer groove 21, when the V-shaped elastic plate 22 is compressed, it will drive the V-shaped elastic plate 22 to move to the left. At this time, by the movement of the V-shaped elastic plate 22 to the left, the rocker 23 will be driven to move. Through the elastic action of the V-shaped elastic plate 22 itself, it can deform when the camera is subjected to external impacts or vibrations, thereby absorbing and dispersing energy;
[0067] At this time, the deformation of the V-shaped spring plate 22 can drive the seesaw 23 to rotate on the fixed block 25. Through the principle of leverage, the deformation of the V-shaped spring plate 22 can push the seesaw 23 to drive the damping rod 26 to slide in the first bracket 13 in the opposite direction, wherein the auxiliary groove 24 is provided to solve the distance change caused by the displacement in the lever process. The damping rod 26 can be squeezed toward the side of the rubber plate 27 installed in the second bracket 14 through the reverse movement of the damping rod 26. Since the rubber plate 27 is made of flexible rubber material, the rubber plate 27 can be squeezed by the damping rod 26 to produce a damping effect on the vibration of the second bracket 14. Compared with the traditional method of directly installing a buffer spring at the bottom of the bracket for vibration reduction, the present solution can reduce the shaking caused by the reverse effect of the deformation of the spring through the V-shaped spring plate 22. The damping rod 26 performs reverse damping extrusion on the second bracket 14 under the action of the deformation of the V-shaped spring plate 22, thereby increasing the damping force of the bracket, especially the external disturbance caused by a series of mechanical vibrations such as blasting and vibration generated during mine operations, so that the camera can still maintain a stable shooting posture in a complex environment.
[0068] The specific use process of the electrostatic composite dust removal mechanism 3 in this scheme is as follows:
[0069] Please refer to the attached Figure 5 and attached Figure 6, on one side of the probe dome glass 12, a dust monitoring device is installed. When the dust monitoring device detects that the dust attached to the surface of the probe dome glass 12 reaches a certain level and affects the monitoring of the camera, at this time, through the electrical action of the dust sensor, it will be transmitted to the controller inside the camera. Under the control of the controller, through electrical conduction, the servo drive motor 31 and the micro motor in the wiper frame 32 will start. At this time, by rotating the servo drive motor 31, the wiper frame 32 can be driven to swing on the surface of the probe dome glass 12. At this time, through electrical transmission, the negative vibration brush 34 starts to be energized and the negative vibration brush 34 generates positive charges. At this time, the positive dust collecting plate 33 starts to be energized and the positive dust collecting plate 33 is charged with positive charges. When the micro motor starts, it will drive the eccentrically connected offset collision block 36 to start rotating. Under the elastic support and reset action of the oscillating spring 35, the eccentric rotation of the offset collision block 36 can be converted into a periodic driving force for the negative vibration brush 34, thereby causing the negative vibration brush 34 to generate reciprocating vibrations. Through this reciprocating vibration, on the one hand, it can enhance the dust cleaning ability of the surface of the probe dome glass 12, and effectively shake off the dust attached to the surface of the probe dome glass 12 through mechanical vibration; on the other hand, during the vibration process, the charges in the negative vibration brush 34 will collide frequently with the dust, which not only helps to separate the dust from the surface of the probe dome glass 12, but also increases the uniformity of the dust charge. When the surface of the component probe dome glass 12 passes through the oscillating cleaning of the component negative vibration brush 34, the dust cleaned off will be charged during the collision process. At this time, those dusts with a certain negative charge will, under the action of the electric field force, quickly move towards the surface of the component positive dust collecting plate 33 with a positive charge and will eventually be adsorbed on the component positive dust collecting plate 33. This process realizes the effective collection and separation of dust, improving the cleaning efficiency and effect.
[0070] In contrast, compressed air blowing needs to rely on an external air source, and may disturb the dust in the air during operation, instead exacerbating the pollution of the lens surface; while the mechanical scraper can remove some dust, but it is powerless against the stubborn particles adhering to the lens; through the design of this solution, not only the dust raising during the cleaning process is reduced, but also the cleaning of the surface of the probe dome glass 12 can be increased through the oscillation of the negative vibration brush 34.
[0071] The specific use process of the modular quick-release mechanism 4 in this solution is as follows:
[0072] Please refer to Appendix Figure 8 to Appendix Figure 10As shown, in the initial state, the shading cover 11 is separated from the box body 1. At this time, the operator covers the shading cover 11 with the box body 1, so that the positioning column on the box body 1 is inserted into the positioning groove provided in the shading cover 11. At this time, after pressing the shading cover 11, the push rod 47 is swung downward, and the push rod 47 drives the pawl 45 to start rotating counterclockwise, so that the pawl 45 and the ratchet 44 are out of the ratchet state. At this time, the operator performs as shown in FIG. Figure 10 The adjustment cylinder 43 is rotated clockwise as shown, which drives the ratchet wheel 44 to start synchronously driving the elliptical plate 51 to start rotating. Figure 8 As shown, by rotating the elliptical plate 51 counterclockwise, the first arc groove 52 and the second arc groove 57 will be driven to squeeze the first push plate 53 and the second push plate 58 respectively. At this time, the first push plate 53 and the second push plate 58 slide toward the outside of the light shielding cover 11 by squeezing each other after the elliptical plate 51 rotates. When the elliptical plate 51 is rotated until the second clamping plate 55 and the squeezing grooves in the first clamping plate 54 squeeze and engage the first clamping frame 41 and the second clamping frame 42 on both sides, and the squeezing grooves of the second push plate 58 squeeze and engage the first clamping frame 41 and the second clamping frame 42 on the upper and lower sides, At this time, the operator can release the push rod 47, and the pawl 45 and the ratchet wheel 44 will be re-engaged under the elastic action of the first torsion spring 46, so that the elliptical plate 51 can be locked at the bottom of the light shielding cover 11, thereby completing the rapid installation of the box body 1 and the light shielding cover 11. Compared with the traditional installation method, when the camera fails, the maintenance personnel can quickly locate and solve the problem, so that the maintenance personnel can easily disassemble and install the camera without complicated tools or skills, and can also quickly disassemble and replace it, reducing downtime and improving maintenance efficiency.
[0073] In addition, the present solution can quickly engage and seal the first clamping frame 41 and the second clamping frame 42 through the second clamping plate 55, the first clamping plate 54 and the auxiliary clamping plate 59. Compared with the local fixation produced by traditional bolt fixation, the present solution adopts distributed extrusion fixation, which can make the sealing gaskets in the first clamping frame 41 and the second clamping frame 42 be evenly squeezed, reducing the damage of the sealing gaskets caused by local extrusion, thereby increasing the service life of the sealing gaskets.
