Description

Technical Field

[0001] This utility model relates to the field of camera technology, specifically to an intrinsically safe image processing camera for mining applications. Background Technology

[0002] In the underground mining environment, mining image processing cameras are key equipment for monitoring underground working conditions, locating and tracking personnel, and providing early warnings of safety hazards. The cleanliness of their lenses directly determines the clarity of image acquisition and the accuracy of data monitoring. Due to the harsh environment underground, characterized by high concentrations of coal dust, water mist, and suspended rock particles, lenses are highly susceptible to contaminant buildup. Therefore, some existing mining cameras are equipped with cleaning brushes for periodically wiping the lenses to maintain monitoring effectiveness.

[0003] However, existing cleaning brush designs have significant flaws: First, most cleaning brushes are installed in an exposed manner without dedicated protective and storage components. Coal dust and fine gravel permeating the mine continuously adhere to the brush bristles or cleaning cloth, forming a stubborn dust layer. When the cleaning brush is used to wipe the lens, the impurities on its surface not only fail to remove lens stains but also scrape the impurities onto the lens surface, causing secondary contamination and even scratching the lens coating, severely damaging image acquisition quality and interfering with the effectiveness of underground monitoring data. Second, existing cleaning brushes lack an automatic cleaning mechanism. After one lens cleaning cycle, the coal dust and debris adhering to its surface cannot be removed promptly and remain. When the cleaning function is activated again, the contaminated brush has completely lost its normal cleaning ability, and the cleaning effect gradually diminishes, making it difficult to guarantee lens cleanliness.

[0004] To maintain the monitoring performance of the equipment, workers need to frequently go down into the mine to disassemble and manually clean the cleaning brushes. This not only increases the intensity and safety risks of underground work, but also reduces the continuous operating capability of the camera due to equipment downtime for maintenance. This makes it unsuitable for the long-term, stable, and automated monitoring needs of underground mines, necessitating optimization and improvement of the existing cleaning brush installation and cleaning structure. Therefore, a mine-use intrinsically safe image processing camera is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intrinsically safe image processing camera for mining applications to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intrinsically safe image processing camera for mining, comprising a camera body, wherein a cleaning brush plate is rotatably connected to the lower center of the front surface of the camera body, and a motor for driving the cleaning brush plate to rotate is installed inside the camera body;

[0007] A groove is provided on the lower side of one side of the front surface of the camera body. A cleaning roller for cleaning the cleaning brush is rotatably connected inside the groove. A temporary storage box is installed on the lower surface of the camera body. Multiple water spray pipes are connected to the temporary storage box, and the water outlets of the multiple water spray pipes are located inside the groove.

[0008] Preferably, the front surface of the groove is fitted with a protective cover that completely covers the groove.

[0009] Preferably, one side of the protective cover is fixedly connected to the front surface of the camera body, and the other three sides of the protective cover are equipped with barrier strips, which are plastic or rubber brush strips.

[0010] Preferably, a cleaning cloth is installed on the side of the cleaning brush plate near the camera body, and plastic or rubber brushes for brushing the cleaning cloth on the cleaning brush plate are evenly installed on the outer surface of the cleaning roller.

[0011] Preferably, a cleaning roller motor for driving the cleaning roller to rotate is installed on one side of the camera body.

[0012] Preferably, the camera body has a controller installed inside, which is electrically connected to the cleaning roller motor and the motor that drives the cleaning brush plate to rotate.

[0013] Preferably, the temporary storage box is connected to an external water supply pipeline, and the outlet ends of the plurality of water spray pipes face the cleaning roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the cleaning roller, water spray pipe and temporary storage box, after the cleaning brush plate completes the lens cleaning, it can automatically enter the groove, where the water spray pipe sprays water to wet the cleaning roller brush, and then the cleaning roller rotates to brush the surface of the cleaning cloth to remove the attached coal dust and impurities. This avoids the problem of secondary contamination of the lens or coating scratches caused by residual pollutants in traditional cleaning brushes, ensuring a stable lens cleaning effect each time, and thus ensuring the accuracy of data for underground working condition monitoring, personnel positioning and hazard early warning.

[0015] The protective cover outside the groove prevents coal dust, gravel, and other debris from entering the groove, avoiding blockage or damage to the cleaning rollers and water spray pipes. The brush strips along the edge of the protective cover do not hinder the movement of the cleaning brushes, further isolating fine coal dust, and can be replaced individually when worn. This significantly reduces the probability of cleaning component failure, extends equipment lifespan, and lowers the cost of frequent disassembly and maintenance, as well as the intensity of underground operations.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an intrinsically safe image processing camera for mining, comprising a camera body 1 for realizing the core functions of image acquisition and processing. A cleaning brush 4 for cleaning its lens area is rotatably connected to the lower center of the front surface of the camera body 1. A drive motor is installed inside the camera body 1 to drive the cleaning brush 4 to reciprocate around the rotatable connection point to adapt to the lens cleaning trajectory. A groove 8 for accommodating cleaning components is provided on one side of the lower front surface of the camera body 1. A cleaning roller 7 for removing impurities attached to the surface of the cleaning brush 4 is rotatably connected inside the groove 8. A temporary storage box 5 for temporarily storing cleaning water is installed on the lower surface of the camera body 1. Three to five water spray pipes 6 for conveying cleaning water are connected to the temporary storage box 5. The water outlets of the multiple water spray pipes 6 are all located inside the groove 8, and the water outlet direction is towards the cleaning roller 7 to provide cleaning water to the cleaning roller 7 and improve its cleaning effect.

[0024] like Figure 1 and Figure 2 As shown: A protective cover 3 that completely covers the opening of the groove 8 is installed on the front surface of the groove 8. The protective cover 3 can prevent coal dust, gravel and other debris in the mine from entering the interior of the groove 8, and prevent the cleaning roller 7 and the water spray pipe 6 from being blocked or damaged by debris, thus ensuring the normal operation of the cleaning components.

[0025] like Figure 5As shown: One side of the protective cover 3 is fixedly connected to the front surface of the camera body 1 by screws, which facilitates disassembly and maintenance in the future; the other three sides of the protective cover 3 are equipped with barrier strips 31, which are elastic plastic or rubber brush strips. Their length is consistent with the length of the corresponding side of the protective cover 3. While not affecting the cleaning brush plate 4 entering and exiting the groove 8, they can further block fine coal dust from entering the groove 8. Moreover, the brush strips can be replaced individually after wear, reducing maintenance costs.

[0026] like Figure 3 and Figure 4 As shown: A microfiber cleaning cloth is attached to the side of the cleaning brush plate 4 near the camera body 1. The cleaning cloth is soft and can avoid scratching the lens surface when cleaning the lens, while efficiently absorbing dust and water stains on the lens. Plastic or rubber brushes are evenly installed in a spiral shape along the outer surface of the cleaning roller 7. The brushes match the cleaning cloth. When the cleaning brush plate 4 rotates into the groove 8, the plastic brush can thoroughly brush the surface of the cleaning cloth, completely removing the dust and impurities adsorbed on the cleaning cloth, ensuring the effectiveness of the cleaning brush plate 4 in cleaning the lens next time.

[0027] like Figure 1 As shown: A cleaning roller motor 2 for driving the cleaning roller 7 to rotate is installed on one side of the camera body 1. Its output shaft is fixedly connected to one end of the cleaning roller 7, which can provide a stable driving force for the cleaning roller 7, ensuring that the cleaning force is moderate and does not damage the cleaning cloth.

[0028] like Figure 1 As shown: The camera body 1 is equipped with a programmable logic controller (PLC). The controller is electrically connected to the cleaning roller motor 2 and the motor that drives the cleaning brush plate 4 to rotate. The automatic control of the start and stop sequence of the two motors first drives the cleaning brush plate 4 to clean the lens, and then drives the cleaning roller 7 to clean the cleaning brush plate 4. At the same time, it supports receiving external control signals to realize manual cleaning, adapting to different working conditions.

[0029] like Figure 2 As shown: the temporary storage box 5 is connected to the external water supply pipeline of the mine through a pipe. The connecting pipe is equipped with a solenoid valve that is electrically connected to the controller. The controller can control the opening and closing of the solenoid valve to realize the automatic replenishment of cleaning water. The outlet of multiple water spray pipes 6 can evenly spray cleaning water onto the brush of the cleaning roller 7, which saves water and improves the cleaning effect of the cleaning roller 7 on the cleaning cloth.

[0030] Working principle: The controller first sends a start signal to the solenoid valve on the pipeline connecting the temporary storage box 5 and the external water supply pipeline. After the solenoid valve opens, the external water supply enters the temporary storage box 5 and is sprayed through multiple water spray pipes 6 connected to the temporary storage box 5 to evenly wet the cleaning cloth, so as to avoid scratching the coating caused by dry wiping the lens later, and at the same time improve the cleaning cloth's ability to absorb coal dust and water stains on the lens surface.

[0031] After the cleaning cloth is wetted, the controller sends a command to the motor that drives the cleaning brush 4 to rotate. The motor starts and drives the cleaning brush 4 to reciprocate around its rotational connection point with the camera body 1. During this process, the wet cleaning cloth adheres tightly to the surface of the camera lens, and through the reciprocating wiping action, it effectively removes coal dust, suspended particles, and water mist residue adhering to the lens, ensuring the cleanliness of the lens and guaranteeing the clarity of image acquisition.

[0032] After the lens cleaning operation is completed, the controller drives the cleaning brush plate 4 to return to its original rotation trajectory and gradually enter the protective cover 3 outside the groove 8 on the front surface of the camera body 1. After the cleaning brush plate 4 is fully inside the protective cover 3, the controller controls the cleaning roller motor 2 to operate, driving the cleaning roller 7 inside the groove 8 to rotate at a uniform speed. Then, the water spray pipe 6 is controlled to supply water to the plastic or rubber brush on the outer surface of the cleaning roller 7, keeping the brush moist. The rotating cleaning roller brush makes full contact with the cleaning cloth on the cleaning brush plate 4, and through the brushing action of the spiral brush, the coal dust and impurities adsorbed on the surface of the cleaning cloth are completely removed; at the same time, the water flow from the water spray pipe 6 can carry away the removed impurities, preventing them from remaining on the cleaning cloth or cleaning roller. After cleaning is completed, the controller closes the solenoid valve, the cleaning roller motor 2, and the motor driving the cleaning brush plate 4. The cleaning brush plate 4 remains stationary inside the protective cover 3, without affecting the normal image acquisition operation of the camera body 1, waiting for the next cleaning instruction.

[0033] 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.
