Description
Technical Field
[0001] This utility model relates to the field of coal pile monitoring technology, specifically a coal pile monitoring device for mine conveyors. Background Technology
[0002] Coal pile monitoring on conveyors is a crucial component of bulk material conveying systems in coal mines, power plants, and ports. It primarily monitors the accumulation of coal or other materials during conveyor operation in real time, preventing equipment malfunctions, downtime, or safety accidents caused by coal pile-up. Mining conveyors require coal pile monitoring devices during operation. To achieve coal pile monitoring and alarm at the transfer point of the tunneling face, a "coal pile algorithm" was developed using computer vision technology to determine if coal pile-up has occurred, ensuring real-time monitoring and timely alarms after pile-up occurs. Specifically, a "belt conveyor coal pile recognition model" is used to identify real-time video data captured by AI cameras installed at the belt conveyor overlap. When the model detects that the coal pile height reaches the system's custom coal pile height line, it triggers a voice alarm and an alarm on the intelligent control platform's monitoring screen.
[0003] However, existing AI cameras have poor dust protection and are easily contaminated by dust when shooting coal piles, requiring frequent cleaning by staff and posing a significant safety hazard. Therefore, we urgently need a coal pile monitoring device for mine conveyors. Utility Model Content
[0004] This utility model provides a coal pile monitoring device for mining conveyors, which can solve the problem that the existing AI cameras have poor dust prevention effect, are easily contaminated by dust when shooting coal pile images, require frequent cleaning by staff, and pose a significant safety hazard.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a coal pile monitoring device for a mining conveyor, including a mounting base, a monitoring mechanism being provided on the top of the mounting base, and a fixing mechanism being provided at one end of the mounting base;
[0006] The monitoring mechanism includes a monitoring box, a protective shell installed on the top of the monitoring box, an AI camera installed inside the protective shell, a fan installed on the top of the monitoring box, an exhaust pipe installed at one end of the fan, a first branch pipe and a second branch pipe fixedly connected to one end of the exhaust pipe, a dustproof frame fixedly connected to one end of the protective shell, a rotating shaft rotatably connected to one end of the protective shell, blades and a connecting rod fixedly connected to the outside of the rotating shaft, and a silicone scraper fixedly connected to one end of the connecting rod.
[0007] Preferably, the monitoring box is equipped with a wireless transmission module, one end of which is connected to the AI camera's wire.
[0008] Preferably, the diameter of the first branch pipe is larger than the diameter of the second branch pipe, and one end of the first branch pipe passes through the dustproof frame and extends to the inside of the dustproof frame.
[0009] Preferably, a solenoid valve is installed on the outside of the second branch pipe, and a dust sensor is connected to one end of the solenoid valve via a wire.
[0010] Preferably, one end of both the first branch pipe and the second branch pipe is fixedly connected to a nozzle, and one end of the second branch pipe is located above the blade.
[0011] Preferably, there are multiple blades, and the multiple blades are arranged in a ring array.
[0012] Preferably, one end of the silicone scraper is attached to one end of the AI camera.
[0013] Preferably, the fixing mechanism includes an adjusting frame, an adjusting plate is slidably connected to the inner side of the adjusting frame, a gear is engaged at one end of the adjusting plate, and a support rod is fixedly connected to the top of the adjusting plate.
[0014] Preferably, the adjustment frame is fixedly connected to the top of the mounting base, and one end of the support rod is fixedly connected to one end of the monitoring box.
[0015] Preferably, one end of the support rod passes through the adjustment frame and extends to the outside of the adjustment frame, and one end of the gear is equipped with a motor.
[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0017] I. This utility model uses screws to fix the mounting base to the monitoring point of the conveyor. Then, an AI camera monitors the coal pile, and a wireless transmission module connected to the AI camera transmits the video data to the monitoring system for identification. When the coal pile height reaches the system's preset height line, an alarm is triggered to alert the staff. During monitoring, a fan blows air, directing it from the exhaust duct to the first and second branch pipes. The first branch pipe then directs the air to the dustproof frame, where it is sprayed out through nozzles at the bottom, forming an air curtain to reduce dust. The system detects the impact of impurities on the AI camera lens. A dust sensor monitors the lens, and when there is a significant amount of dust, a solenoid valve connected to the dust sensor opens. This allows air from the fan to reach the nozzle at the bottom of the second branch pipe and blow onto the blades. The rotating shaft, in conjunction with the blowing blades, allows the shaft and blades to rotate, which in turn rotates the connecting rod outside the shaft. This causes the silicone scraper at the connecting rod to clean the lens, thus preventing dust from affecting the lens. This eliminates the need for frequent manual cleaning and improves monitoring quality.
[0018] II. After the mounting base is fixed in position, the motor is started to drive the gear to rotate according to the required coal pile height. This drives the adjusting plate meshing with the gear to rise, which in turn drives the support rod to rise, thereby raising the monitoring box connected to it. This allows for adjustment of the monitoring height of the AI camera, achieving the effect of conveniently adjusting the monitoring height. Attached Figure Description

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0025] Example 1:
[0026] Please see Figure 1-4 This utility model provides a technical solution:
[0027] A coal pile monitoring device for a mining conveyor includes a mounting base 1, a monitoring mechanism 2 on the top of the mounting base 1, and a fixing mechanism 3 at one end of the mounting base 1.
[0028] The monitoring unit 2 includes a monitoring box 21. A protective shell 22 is installed on the top of the monitoring box 21. An AI camera 23 is installed inside the protective shell 22. A fan 24 is installed on the top of the monitoring box 21. An exhaust pipe 25 is installed at one end of the fan 24. One end of the exhaust pipe 25 is fixedly connected to a first branch pipe 26 and a second branch pipe 27. A dustproof frame 28 is fixedly connected to one end of the protective shell 22. A rotating shaft 29 is rotatably connected to one end of the protective shell 22. A blade 201 and a connecting rod 202 are fixedly connected to the outside of the rotating shaft 29. A silicone scraper 203 is fixedly connected to one end of the connecting rod 202.
[0029] Through the above technical solution, the mounting base 1 is fixed to the monitoring point of the conveyor with screws. Then, the AI camera 23 monitors the coal pile, and the video data is transmitted to the monitoring system for identification through a wireless transmission module connected to the AI camera 23. When the coal pile height reaches the system's custom coal pile height line, an alarm is triggered to remind the staff. During the monitoring process, the fan 24 blows air and guides the air from the exhaust pipe 25 to the first branch pipe 26 and the second branch pipe 27. The first branch pipe 26 then guides the air to the dustproof frame 28, and sprays it out through the nozzle at its bottom to form an air curtain, thereby reducing the impact of dust and other impurities on the lens of the AI camera 23. At the same time, the dust sensor 12 detects the lens of the AI camera 23. When the lens... When there is a lot of dust, the solenoid valve 11 connected to the dust sensor 12 wire opens, allowing the air from the fan 24 to reach the nozzle at the bottom of the second branch pipe 27 and then blow onto the blades 201. Due to the setting of the rotating shaft 29, the rotating shaft 29 and the blades 201 can rotate, thereby driving the connecting rod 202 outside the rotating shaft 29 to rotate, so that the silicone scraper 203 at the connecting rod 202 cleans the lens, thus completing the operation of preventing dust from affecting the lens. It eliminates the need for frequent manual cleaning and achieves the effect of improving monitoring quality. The connection between the wireless transmission module and the AI camera 23 and the connection between the dust sensor 12 and the solenoid valve 11 are existing technologies, and their internal wiring connections are known technologies, so they will not be described in detail.
[0030] Specifically, the monitoring box 21 is equipped with a wireless transmission module, one end of which is connected to the AI camera 23 via a wire.
[0031] The above technical solution enables the data captured by the AI camera 23 to be transmitted to the monitoring system by connecting one end of the wireless transmission module to the wire of the AI camera 23.
[0032] Specifically, the diameter of the first branch pipe 26 is larger than the diameter of the second branch pipe 27, and one end of the first branch pipe 26 passes through the dustproof frame 28 and extends to the inside of the dustproof frame 28.
[0033] With the above technical solution, the diameter of the first branch pipe 26 is larger than the diameter of the second branch pipe 27, so that when the first branch pipe 26 and the second branch pipe 27 are opened at the same time, the air volume of the first branch pipe 26 is greater than that of the second branch pipe 27, thus avoiding affecting the air curtain.
[0034] Specifically, a solenoid valve 11 is installed on the outside of the second branch pipe 27, and a dust sensor 12 is connected to one end of the solenoid valve 11.
[0035] The above technical solution enables the solenoid valve 11 to work in conjunction with the dust sensor 12 to intermittently clean the lens.
[0036] Specifically, a nozzle is fixedly connected to one end of both the first branch pipe 26 and the second branch pipe 27, with one end of the second branch pipe 27 located above the blade 201.
[0037] The above technical solution can improve the intensity of airflow through the nozzle, and one end of the second branch pipe 27 is located above the blade 201 so that the blade 201 can be blown directly.
[0038] Specifically, multiple blades 201 are provided, and the multiple blades 201 are arranged in a ring array.
[0039] Through the above technical solution, multiple blades 201 are arranged in a ring array, which allows the rotating shaft 29 to rotate better.
[0040] Specifically, one end of the silicone scraper 203 is attached to one end of the AI camera 23.
[0041] Through the above technical solution, one end of the silicone scraper 203 is attached to the lens of the AI camera 23, which allows for better cleaning of the lens.
[0042] Example 2:
[0043] Please see Figure 1 , Figure 3 Furthermore, in conjunction with Embodiment 1, it is further found that the fixing mechanism 3 includes an adjusting frame 31, an adjusting plate 32 is slidably connected to the inner side of the adjusting frame 31, a gear 33 is engaged at one end of the adjusting plate 32, and a support rod 34 is fixedly connected to the top of the adjusting plate 32.
[0044] The adjustment frame 31 is fixedly connected to the top of the mounting base 1, and one end of the support rod 34 is fixedly connected to one end of the monitoring box 21.
[0045] One end of the support rod 34 passes through the adjusting frame 31 and extends to the outside of the adjusting frame 31, and a motor is installed at one end of the gear 33.
[0046] With the above technical solution, after the mounting base 1 is fixed in position, the motor is started to drive the gear 33 to rotate according to the coal pile height to be monitored, thereby driving the adjusting plate 32 meshing with it to rise, which in turn drives the support rod 34 to rise, thereby raising the monitoring box 21 connected to it, and thus adjusting the monitoring height of the AI camera 23, so as to achieve the effect of easy adjustment of the monitoring height.
[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
