Description

Technical Field

[0001] This invention belongs to the field of camera equipment technology, specifically an intrinsically safe camera for mining and its cleaning components. Background Technology

[0002] Underground mining involves multi-directional vibrations from mechanical operation and blasting. Traditional cameras lack specific buffer structures, and the vibration force is easily transmitted to the lens, causing blurry images and ghosting, making it impossible to accurately capture the monitored area. At the same time, underground mining operations generate a large amount of suspended dust, which easily adheres to the lens surface. Furthermore, traditional cameras have a single dust removal method, making it difficult to actively intercept dust that approaches the lens, resulting in a continuous decline in image clarity.

[0003] Patent application CN202310855725.8 discloses an automatic dust removal mining camera, which includes an adjustment mechanism and a camera body mounted on the adjustment mechanism. The adjustment mechanism is used to adjust the shooting angle of the camera body, and the camera body is equipped with a protective cover. It also includes a right-angle air duct, which is located below the camera body. One opening of the right-angle air duct is vertically upward, and the other opening is horizontal. A fixing plate is installed inside the right-angle air duct. By performing a dual automatic dust removal process of sweeping and air blowing to remove dust adhering to the lens of the camera body, the dust removal method of the camera body can be greatly simplified, and the dust removal of the camera body can be achieved quickly. This saves a lot of manpower and time compared to manual wiping and cleaning, and improves work efficiency. Although the above solution achieves the cleaning of the camera surface, it cannot select the appropriate cleaning state according to the contamination state of the lens during the cleaning process, which may lead to over-cleaning and wear on the lens, affecting the service life of the camera.

[0004] Meanwhile, due to the strong adhesion of dust in the underground part of the mine, simple vacuuming alone cannot completely remove it. Traditional cleaning methods are either incomplete or cause the coating to wear down when the cleaning tools are used to directly contact the lens.

[0005] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes an intrinsically safe camera for mining and its cleaning components. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems. This invention provides an intrinsically safe camera for mining and its cleaning components, which have the advantages of quickly removing dust and accurately cleaning the lens.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intrinsically safe camera for mining, comprising a camera assembly, a buffer assembly connected to the camera assembly, and a rotating column connected to the end of the buffer assembly away from the camera assembly; The buffer assembly includes a base, one end of which is connected to the rotating column, a buffer column is connected to the end of the base away from the rotating column, a connecting plate is connected to the end of the buffer column away from the base, the connecting plate is connected to the camera assembly, and a plurality of edge buffer strips are connected between the base and the connecting plate.

[0008] Preferably, the camera assembly includes a housing, one end of which is provided with a lens, and the connecting plate is in contact with the housing.

[0009] Preferably, a connecting rod is rotatably provided at the end of the rotating column away from the buffer assembly, a rotating part is connected at the end of the connecting rod away from the rotating column, and a fixing block for connecting the camera assembly is connected at the end of the rotating part away from the connecting rod.

[0010] The present invention also includes a cleaning component for cleaning an intrinsically safe camera used in mining, including a shielding component connected to the camera component, and the shielding component being located on the end of the camera component away from the buffer component; The shielding assembly includes a dust shield, which has a dust suction chamber. A dust removal groove is formed through the dust suction chamber at one end near the lens, and the position of the dust removal groove corresponds to the position of the lens. A vent is formed on the side of the dust suction chamber away from the dust removal groove, and the opening direction of the vent is located at the end away from the camera assembly.

[0011] Preferably, an air pump is connected inside the dust suction chamber to facilitate the flow of gas within the chamber.

[0012] Preferably, a connecting hole is provided through the dust shield, and the camera assembly is connected through the connecting hole.

[0013] Preferably, a cleaning component and a washing component are connected to one end of the dust shield near the camera component, and the cleaning component and the washing component are located at both ends of the dust removal trough distributed along its length.

[0014] Preferably, the cleaning assembly includes a carrier shell with a carrier cavity. A telescopic part is rotatably provided inside the carrier cavity. One end of the telescopic part is connected to a rotating shaft. A rotating shaft is connected to one end of the rotating shaft along its length. A mounting plate is connected to the end of the rotating shaft away from the rotating shaft. A rotating disk is connected to the end face of the mounting plate. An air blowing port for dust removal is provided on the rotating disk. Multiple cleaning brushes are arrayed on the circumference of the rotating disk.

[0015] Preferably, the cleaning assembly includes a connecting shell, a rotating cavity is provided on the connecting shell, an adjusting part is connected inside the rotating cavity, an adjusting shaft is connected to the adjusting part, and a cleaning head is provided on one end of the adjusting shaft.

[0016] Preferably, a dust concentration sensor is connected to the shielding component.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The buffer assembly and rotation adjustment structure work together to achieve stable and flexible shooting by the camera. In the buffer assembly, the vibration force transmitted from the base in the mine is offset by the buffer column, and the evenly distributed edge buffer strips further weaken multi-directional vibration, significantly reducing the vibration amplitude of the housing and lens, and avoiding image blurring and ghosting; the combination structure of the rotating part, rotating column and connecting rod can precisely adjust the shooting angle through the stepper motor. Combined with the real-time analysis of the image by the image analysis module, it can quickly compensate for angle deviations, ensuring that the key monitoring area is always within the lens's optimal shooting range. This not only ensures shooting stability in vibration environments, but also meets the precise monitoring needs of complex underground mining scenarios.

[0018] 2. The shielding component, dust collection structure, and dust concentration sensor work together to construct a tiered active dust removal system. The dust shield reduces direct dust adhesion through physical shielding. The suction pump in the dust collection chamber, together with the dust collection groove and ventilation holes, forms a directional airflow. The power is dynamically adjusted according to the dust concentration detected by the sensor. At low concentrations, a slight negative pressure is used to adsorb suspended dust, while at high concentrations, full power is used to quickly remove dust near the lens, and an early warning is sent to the dispatch center. The suction pump works in conjunction with the air outlet of the cleaning component to promptly adsorb the blown-away dust during the dust removal process, avoiding secondary pollution, effectively reducing the dust adhesion rate to the lens, and ensuring image clarity.

[0019] 3. The images captured by the sweeping, cleaning, and camera components work together to achieve precise, tiered lens cleaning. For light contamination, only pulsed high-pressure airflow from the air nozzle removes floating dust, avoiding unnecessary wear on the cleaning brush. For moderate contamination, airflow is used first, followed by precise adjustment of the cleaning brush angle via the telescopic and rotating shafts, with continuous low-flow airflow guiding dust adsorption. For heavy contamination, the cleaning head sprays atomized cleaning fluid to soften the stains, the cleaning brush cleans at low speed, and then high-power airflow dries the lens. The entire process is controlled by an image analysis module that detects sharpness and implements closed-loop control, ensuring lens cleanliness while minimizing damage to the lens coating and extending the equipment's lifespan.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-9 As shown, the present invention discloses an intrinsically safe camera for mining, including a camera component 1, a buffer component 7 for stabilizing the shooting state of the camera component 1 connected to the camera component 1, and a rotating column 6 for supporting the buffer component 7 connected to the end of the buffer component 7 away from the camera component 1.

[0023] During use, the position of the camera component 1 is determined, and the camera angle of the camera component 1 is stabilized by the buffer component 7 to ensure the stability of the camera component 1 during the recording process.

[0024] The buffer assembly 7 includes a base 701 for supporting the connection. One end of the base 701 is connected to the rotating column 6, and the end of the base 701 away from the rotating column 6 is connected to a buffer column 704 for counteracting vibration. The end of the buffer column 704 away from the base 701 is connected to a connecting plate 703, which is connected to the camera assembly 1. Therefore, during use, when the position of the camera assembly 1 vibrates, the vibration is transmitted to the base 701, and then through the base 701 to the buffer column 704, causing the buffer column 704 to counteract the vibration on the base 701 and reduce the transmission of vibration. The vibration force of the connecting plate 703 is weakened, ensuring the shooting stability of the camera assembly 1. At the same time, since the direction of the vibration force is different, the vibration force transmitted by the base 701 cannot be effectively offset by the buffer column 704 alone. Multiple edge buffer strips 702 are connected between the base 701 and the connecting plate 703, and the multiple edge buffer strips 702 are evenly distributed around the buffer column 704 to support the area of ​​the base 701 and the connecting plate 703 other than the support position of the buffer column 704, thereby reducing the impact of multi-directional vibration force on the connecting plate 703 and improving the shooting stability of the camera assembly 1.

[0025] Furthermore, the camera assembly 1 includes a housing 101 for protecting the electronic board, one end of the housing 101 is provided with a lens 102 for taking pictures, and a connecting plate 703 is in contact with the housing 101.

[0026] Furthermore, to ensure a stable connection of the camera assembly 1, a connecting rod 5 is rotatably provided at the end of the rotating column 6 away from the buffer assembly 7. The end of the connecting rod 5 away from the rotating column 6 is connected to a rotating part 4 for adjusting the shooting angle of the camera assembly 1. The end of the rotating part 4 away from the connecting rod 5 is connected to a fixing block 3 for fixing the camera assembly 1 to the outside world. Thus, during installation and fixing, the fixing block 3 is used to fix it to the external wall. Then, according to the shooting requirements of the camera assembly 1, the rotation angle of the rotating part 4 is adjusted to change the angle of the connecting rod 5. At the same time, according to the installation requirements, the angle between the rotating column 6 and the connecting rod 5 is adjusted to fine-tune the shooting area of ​​the camera assembly 1, ensuring the shooting requirements and connection stability of the camera assembly 1.

[0027] Meanwhile, an integrated image analysis module is installed inside the housing 101 of the camera component 1 to analyze the captured image of the lens 102 in real time, identify the clarity and coverage of the monitored area, and receive remote control commands through the underground industrial Ethernet to obtain preset monitoring angle parameters.

[0028] Based on image analysis results or remote commands, the core control module drives the stepper motors built into the rotating part 4 and the rotating column 6 to achieve precise adjustment of the shooting angle. When a critical area is detected to be deviating from the shooting frame, the angle compensation value is calculated, and the rotating part 4 is controlled to rotate to adjust the horizontal angle of the connecting rod 5. At the same time, the angle between the rotating column 6 and the connecting rod 5 is adjusted to ensure that the critical area is always within the optimal shooting range of the lens 102.

[0029] Since the camera component 1 in this invention is mainly used in mining, it is easily covered by smoke and dust generated in the mine during use, which affects the shooting effect of the camera component 1.

[0030] During the equipment installation phase, the camera is first connected to external fixed structures such as the mine wall using fixing block 3, providing a stable support foundation for the entire camera and ensuring that the equipment will not shift as a whole in environments with vibration and impact in the mine. The core control module, as the command center, first receives the preset monitoring angle parameters. At the same time, the image analysis module integrated inside the housing 101 of the camera component 1 analyzes and identifies the key monitoring areas, clarity, and coverage of the image captured by the lens 102 in real time, and feeds this data back to the core control module.

[0031] When the shooting angle needs to be adjusted, the core control module drives the stepper motors built into the rotating part 4 and the rotating column 6. The rotating part 4 changes the horizontal angle of the connecting rod 5 by rotating, and the rotating column 6 rotates relative to the connecting rod 5 to adjust the angle between them. Through these two dimensions of angle adjustment, the shooting area of ​​the camera component 1 can be precisely fine-tuned. If the image analysis module detects that the key area deviates from the shooting screen, it will immediately calculate the angle compensation value and transmit it to the core control module to control the rotating part 4 and the rotating column 6 to make targeted adjustments, ensuring that the key area is always within the optimal shooting range of the lens 102, thus ensuring the accuracy of the shooting.

[0032] During the recording process, the buffer assembly 7 plays a crucial role in ensuring the stability of the recording. Underground mining operations are often accompanied by mechanical vibrations. These vibrations are transmitted through the fixed block 3, rotating part 4, and connecting rod 5 to the rotating column 6, and then from the rotating column 6 to the base 701 of the buffer assembly 7. The base 701 disperses the vibrations to the buffer column 704, which uses its structural characteristics to offset some of the vibrations, reducing the intensity of the vibration transmitted to the connecting plate 703. Simultaneously, multiple edge buffer strips 702, evenly distributed around the buffer column 704 between the base 701 and the connecting plate 703, provide comprehensive auxiliary support to the area between them, except for the support point of the buffer column 704. This effectively weakens vibrations from different directions, preventing the problem of a single buffer column 704 not completely offsetting complex multi-directional vibrations. Ultimately, after the multi-layer vibration reduction treatment of the buffer assembly 7, the vibration amplitude of the camera assembly 1 housing 101 connected to the connecting plate 703 is significantly reduced, ensuring the stability of the image captured by the lens 102 and avoiding problems such as image blurring and ghosting caused by vibration, thus ensuring the validity of the recording data.

[0033] The present invention also includes a cleaning component for cleaning an intrinsically safe camera used in mining, including a shielding component 2 for reducing dust interference with the housing 101. The shielding component 2 is connected to the camera component 1 to ensure that the position of the shielding component 2 is stable, and the shielding component 2 is located at the end of the camera component 1 away from the buffer component 7. The shielding component 2 is used to prevent dust in the air from falling on the camera component 1, thereby improving the cleanliness of the camera component 1 and reducing the impact of dust on the camera component 1.

[0034] To reduce the interference of airborne dust on the lens 102, the shielding assembly 2 includes a dust shield 201 for protecting the housing 101 from dust. The dust shield 201 has a dust suction chamber 205 for drawing out dust. A dust removal groove 204 is provided through the end of the dust suction chamber 205 near the lens 102 to absorb dust near the lens 102. The position of the dust removal groove 204 corresponds to the position of the lens 102, ensuring that the dust removal groove 204 can evenly draw out dust near the lens 102. The dust suction chamber 205 is located away from the lens 102. A vent 203 is provided on one side of the dust tank 204 for the air flow in the dust suction chamber 205. The opening direction of the vent 203 is located at the end away from the camera component 1. Therefore, when the camera component 1 is in use, the dust tank 204 absorbs the dust near the lens 102, causing the air to move the dust in the dust suction chamber 205, keeping the dust away from the lens 102 and reducing the dust adhesion rate on the lens 102. At the same time, after passing through the dust suction chamber 205, the dust is discharged from the vent 203, keeping the dust away from the lens 102 and improving the shooting clarity of the lens 102.

[0035] Furthermore, in order to improve the suction power of the suction chamber 205 for dust in the air, an air pump is connected inside the suction chamber 205 to promote the flow of gas inside the suction chamber 205. The air pump drives the flow of gas inside the suction chamber 205, so that the dust removal tank 204 can effectively absorb the dust near the lens 102.

[0036] In low-concentration dust environments, the air pump operates at 30% of its rated power to maintain a slight negative pressure within the suction chamber 205, adsorbing suspended dust and reducing the probability of lens contamination.

[0037] In environments with medium concentrations of dust, the power of the air pump is increased to 60%, which increases the adsorption force of the dust removal tank 204 and quickly removes dust near the lens.

[0038] In environments with high concentrations of dust (such as after blasting or during periods of high dust levels), the air pump operates at 100% of its rated power. At the same time, the core control module sends dust warning information to the dispatch center through the underground network to remind workers to take precautions. Once the dust concentration drops below medium concentration, the air pumping power is automatically adjusted back to reduce energy consumption.

[0039] Furthermore, in order to improve the connection stability of the dust cover plate 201, a connection hole 202 is provided through the dust cover plate 201, and the connection hole 202 is used to snap and fix it with the protrusion on the camera component 1.

[0040] Furthermore, even though the dust near the lens 102 is absorbed by the suction chamber 205, it is still impossible to completely prevent dust from covering the lens 102. Therefore, the lens 102 still needs to be cleaned during use. Thus, the dust shield 201 is connected to a cleaning component 8 for cleaning dust on the lens 102 and a washing component 9 for washing the surface of the lens 102 with water at one end near the camera assembly 1. The cleaning component 8 and the washing component 9 are located at both ends of the dust removal tank 204 along the length direction, ensuring that the cleaning component 8 and the washing component 9 will not interfere with the operation of the dust removal tank 204, and also ensuring that the cleaning component 8 and the washing component 9 will not damage the camera assembly 1 during use.

[0041] Furthermore, to ensure that the cleaning assembly 8 cleans the dust on the lens 102, the cleaning assembly 8 includes a support shell 801 for fixing, and a support cavity 8011 for storing the device. The support shell 801 is connected to the dust shield 201. The opening of the support cavity 8011 is located at the end away from the dust shield 201. A telescopic part 802 for length adjustment is rotatably provided inside the support cavity 8011. One end of the telescopic part 802 is connected to a rotating shaft 803 for overall adjustment of the cleaning angle. A rotating shaft 804 for fine adjustment of the cleaning angle is connected to one end of the rotating shaft 803 along its length. The end of the rotating shaft 804 away from the rotating shaft 803 is connected to a mounting plate 805 for stable connection. Thus, in use, the relative rotation between the telescopic part 802 and the support cavity 8011 is controlled, driving the rotating shaft 803... The positions of the rotating shaft 804 and the mounting plate 805 are moved, and the length of the telescopic part 802 is adjusted. The angle of the rotating shaft 803 is changed according to the angular offset between the mounting plate 805 and the lens 102, thereby adjusting the angle of the rotating shaft 804 and the mounting plate 805. Then, the angle of the mounting plate 805 is adjusted by rotating the rotating shaft 804 to ensure that the position of the mounting plate 805 is directly facing the lens 102. A rotating disk 806 for cleaning the lens 102 is connected to the end face of the mounting plate 805. An air blowing port 8061 for removing floating dust is opened on the rotating disk 806. A blower for delivering clean air is installed inside the rotating disk 806 to ensure that the air generated by the air blowing port 8061 can meet the cleaning requirements of the lens 102. Multiple cleaning brushes 807 for cleaning dust with strong adhesion are arrayed on the circumference of the rotating disk 806.

[0042] During use, when the mounting plate 805 is positioned directly opposite the lens 102, the cleaning method for the dust on the lens 102 is selected according to the degree to which the lens 102 is covered with dust.

[0043] When only a blurry image appears on the lens 102, only the air outlet 8061 is controlled to work, so that the air outlet 8061 releases gas to clean the dust on the lens 102 and restore the clarity of the lens 102. This reduces the number of times the cleaning brush 807 cleans the lens 102, avoids wear and tear on the lens 102, and improves the service life of the lens 102.

[0044] When the image captured by the lens 102 is abnormally blurry or remains blurry even after blowing air through the air outlet 8061, the angle of the mounting plate 805 is deflected after the dust on the lens 102 is blown away by the air outlet 8061, causing the cleaning brush 807 to come into contact with the surface of the lens 102. The rotating disk 806 is then controlled to drive the cleaning brush 807 to rotate, so that the cleaning brush 807 cleans the surface of the lens 102, ensuring the clarity of the image captured by the camera assembly 1.

[0045] Specifically, when the pollution is mild, only the air outlet 8061 of the cleaning component 8 is activated to operate in a pulse-type air blowing mode, using high-pressure gas to remove floating dust and avoid unnecessary contact wear of the cleaning brush 807; at the same time, the air pump maintains medium power operation to promptly absorb the blown-off dust and prevent secondary pollution.

[0046] When the pollution level is moderate, the air blower 8061 is activated first to pulse air blow away the floating dust. Then, the core control module adjusts the extension length of the cleaning component 8 through the telescopic part 802, and precisely adjusts the angle of the rotating disk 806 through the rotating shaft 803 and the rotating shaft 804, so that the cleaning brush 807 touches the surface of the lens 102 at a 30° angle. The rotating disk 806 is controlled to rotate, and the cleaning brush 807 performs spiral cleaning on the lens surface. During the cleaning process, the air blower 8061 continuously blows air at a low flow rate to promptly send the dust generated during cleaning to the dust collection tank 204. After cleaning is completed, the air blower 8061 is activated again to pulse air blow away the residual dust.

[0047] When the contamination is severe, the cleaning process for moderate contamination is executed first. After cleaning, the lens sharpness is rechecked through the image analysis module. If the sharpness is still <70%, the cleaning component 9 is activated. The cleaning head 904 is precisely moved to the front of the lens 102 through the adjustment unit 902 and the adjustment shaft 903. The cleaning head 904 sprays atomized cleaning fluid to cover the lens surface. After settling, the cleaning brush 807 is controlled to clean again at low speed. At the same time, the air pump runs at high power to adsorb the mixture of sewage and dust. After cleaning, the air outlet 8061 blows air continuously at 80% power to achieve rapid drying of the lens and avoid watermarks. After drying, the image analysis module rechecks again until the lens sharpness is ≥80%, at which point the cleaning process automatically terminates.

[0048] Furthermore, to ensure the cleaning efficiency of the camera component 1, the cleaning component 9 includes a connecting shell 901 for connection and fixation. The connecting shell 901 has a rotating cavity 9011 for storage. The rotating cavity 9011 is connected to an adjustment part 902 for length adjustment. The adjustment part 902 is connected to an adjustment shaft 903. The functions of the adjustment part 902 and the adjustment shaft 903 are the same as those of the telescopic part 802 and the rotating shaft 803. One end of the adjustment shaft 903 is provided with a cleaning head 904 for washing the lens 102. When the lens 102 still has a relatively blurry area after cleaning with the cleaning component 8, the cleaning head 904 is controlled to rinse the lens 102. The cleaning component 8 can also be controlled to perform a secondary cleaning of the lens 102 according to the cleaning efficiency of the cleaning head 904 to ensure the cleanliness of the lens 102.

[0049] Meanwhile, after the cleaning head 904 cleans the lens 102, the air outlet 8061 dries the surface of the lens 102 to reduce watermarks caused by the natural drying of water droplets.

[0050] Furthermore, a dust concentration sensor is connected to the shielding component 2, and the dust concentration detected by the dust concentration sensor is uploaded to the control module. The dust concentration sensor is used to control the dust collection efficiency of the suction chamber 205, and the surface of the lens 102 is cleaned in a timely manner according to the dust concentration sensor and the image clarity of the camera component 1.

[0051] The dust concentration sensor uses the principle of laser scattering to detect the dust concentration in the area around the lens 102 in real time and transmits the data to the core control module. At the same time, the image analysis module identifies the grayscale value and sharpness parameters of the image captured by the lens 102 to help determine the degree of dust adhesion on the lens surface.

[0052] First, the dust shield 201 of the shielding assembly 2 is connected to the housing 101 of the camera assembly 1 through the connecting hole 202, forming a physical protection for the end where the lens 102 is located, reducing the probability of dust in the air falling directly onto the surface of the lens 102 and the housing 101, thus reducing the risk of pollution at the source. The dust suction chamber 205 opened in the dust shield 201 is the core structure of active dust removal. The dust removal groove 204 opened at the end of the dust suction chamber 205 near the lens 102 is precisely aligned with the position of the lens 102, ensuring that the dust removal range can completely cover the area around the lens 102; the vent 203 opened on the side of the dust suction chamber 205 away from the dust removal groove 204 opens away from the camera assembly 1, preventing the exhaust dust-laden airflow from re-contaminating the lens 102.

[0053] When the air pump inside the dust suction chamber 205 is working, it will cause a stable airflow channel to be formed inside the dust suction chamber 205. Outside air carries dust near the lens 102 into the dust suction chamber 205 through the dust removal groove 204, and then discharges through the vent 203, forming a continuous active dust suction effect, effectively reducing the adhesion of suspended dust on the surface of the lens 102.

[0054] The dust concentration sensor connected to the shielding component 2 uses the laser scattering principle to detect the dust concentration around the lens 102 in real time and transmits the data to the core control module, providing a basis for adjusting the power of the air pump and starting the cleaning process. When the dust concentration is low, the air pump operates at 30% of its rated power to maintain a slight negative pressure in the suction chamber 205, which can achieve basic vacuuming while avoiding energy waste.

[0055] In environments with medium-concentration dust, the power of the air pump is increased to 60% to enhance the adsorption force of the dust collection tank 204 and quickly remove dust near the lens 102. If high-concentration dust is detected (such as after underground blasting or during periods of dust dispersion), the air pump immediately operates at 100% rated power. At the same time, the core control module sends a dust warning message to the dispatch center via the underground industrial Ethernet to remind operators to take protective measures. Once the dust concentration drops below medium concentration, the power of the air pump is automatically adjusted back to achieve a dynamic balance between intelligent energy saving and efficient dust removal.

[0056] When dust has accumulated on the surface of lens 102, the image analysis module identifies the grayscale value and sharpness parameters of the captured image, and combines the dust concentration sensor data to determine the degree of contamination of lens 102, and triggers the corresponding cleaning process.

[0057] In the case of light contamination, only the air outlet 8061 of the cleaning component 8 is activated to remove the floating dust on the surface of the lens 102 with pulsed high-pressure gas, avoiding unnecessary contact and wear between the cleaning brush 807 and the lens 102, and extending the service life of the lens 102; at the same time, the air pump maintains medium power operation to promptly absorb the dust blown away, preventing the dust from spreading and re-adhering to the surface of the lens 102, causing secondary contamination.

[0058] For moderate pollution, the cleaning process consists of three steps: First, pulse air blowing is activated from the air outlet 8061 to remove surface dust. Second, the core control module drives the telescopic part 802 of the cleaning component 8 to rotate and adjust its length within the bearing cavity 8011 of the bearing housing 801, thereby moving the rotating shaft 803. The angle of the rotating shaft 804 is then adjusted by the rotation of the rotating shaft 803, ultimately ensuring that the rotating disk 806 on the mounting plate 805 is precisely aligned with the lens 102, and that the cleaning brush 807 is at a 30° angle to the surface of the lens 102. The angled touch ensures effective cleaning while preventing damage to the lens coating by the cleaning brush 807. The third step involves controlling the rotating disk 806 to rotate, allowing the cleaning brush 807 to perform a spiral cleaning of the lens 102 surface. During cleaning, the air outlet 8061 continuously blows air at a low flow rate, guiding the dust generated during cleaning towards the dust collection trough 204, ensuring that the dust is promptly sucked into the suction chamber 205. After cleaning, the air outlet 8061 is activated again for pulsed air blowing to remove any remaining traces of dust from the lens 102 surface.

[0059] If the contamination is severe, after the medium-contamination cleaning process is completed, the image analysis module immediately re-examines the sharpness of lens 102. If the sharpness is still below 70%, the cleaning component 9 is activated for deep cleaning. The adjustment part 902 of the cleaning component 9 adjusts its length within the rotating cavity 9011 of the connecting housing 901, driving the adjustment shaft 903 to move precisely to the front of the lens 102. The cleaning head 904 sprays cleaning fluid, evenly covering the surface of the lens 102, using the cleaning fluid to soften stubborn stains. After a preset time, the core control module drives the cleaning brush 807 of the cleaning component 8 to clean the surface of the lens 102 again at a lower speed, avoiding scratches on the wet surface of the lens 102 caused by high-speed rotation. At the same time, the air pump operates at high power to quickly absorb the mixture of wastewater and dust generated during cleaning, preventing wastewater from remaining on the surface of the lens 102 and forming watermarks. After cleaning, the air outlet 8061 blows air continuously at 80% power to accelerate the drying of the surface of the lens 102, preventing watermarks from affecting the image sharpness. After drying, the image analysis module re-checks the sharpness of the lens 102 until the sharpness is ≥80%, at which point the cleaning process automatically terminates, restoring the normal shooting function of the camera component 1.
