Description

Technical Field

[0001] The utility model relates to the technical field of coal mining and transportation equipment, in particular to a coal pile protection system for a belt conveyor. Background Art

[0002] Coal mine transportation systems, comprising equipment such as mine cars, tracks, hoists, and belt conveyors, are used to transport coal from the mine to the surface, and are a crucial component of coal mine production. Currently, underground coal mine transportation systems primarily utilize belt conveyors to transport raw coal mined from the working face to the surface for washing and processing. Belt conveyors offer advantages such as a simple structure, ease of use, ease of maintenance, high transport capacity, low power consumption, labor savings, and low operating costs. However, during daily production and continuous use, belt conveyors often experience problems such as coal accumulation, slippage, tearing, and deviation, severely restricting production and causing significant economic losses to the mine.

[0003] To solve this problem, a coal electrode type coal pile protection device has been proposed. The coal electrode type coal pile protection device is widely used because of its more scientific operating principle and more reliable operation. However, this type of sensor and grounding cable are easily affected by external harsh environments such as coal dust intrusion, moisture corrosion, etc., and often cannot accurately monitor the coal pile fault signal in a timely manner. At the same time, this type of coal pile protection is hanging, which is prone to collision and has a high probability of misoperation, resulting in unsatisfactory use effect and reliability.

[0004] When using inclined coal stacking devices and coal electrode type coal stacking devices, in actual production processes, workers often arbitrarily adjust the horizontal position or height of the protective device to reduce the probability of malfunction and increase the operating rate. This can cause the protector to lose its protective function and, in serious cases, may cause a safety accident. Therefore, this application proposes a belt conveyor coal stacking protection system to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0038] In order to help those skilled in the art better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0039] Example 1:

[0040] like Figure 1 As shown, a belt conveyor coal pile protection system includes: a video acquisition module, an AI recognition module, an early warning and shutdown module, and a system management module;

[0041] The video acquisition module includes:

[0042] High-definition camera: The high-definition camera is installed at the transfer point of the belt conveyor through a mounting bracket to capture the accumulation of coal in real time. The camera has high resolution and wide-angle field of view to ensure that the full picture of the transfer point can be captured.

[0043] Video encoder: The video encoder encodes the video signal captured by the high-definition camera and converts it into a digital signal for subsequent analysis and processing.

[0044] The AI ​​recognition module includes:

[0045] The image processing unit performs image processing on the digital video signal transmitted by the video encoder, including operations such as denoising, enhancement, and scaling to improve image quality.

[0046] The AI ​​recognition algorithm utilizes deep learning and other artificial intelligence technologies to identify and analyze processed images. The algorithm accurately identifies coal accumulation, including height, shape, and location. The AI ​​recognition algorithm's output determines whether the coal accumulation has reached a dangerous level. If a preset threshold is reached, an early warning or shutdown signal is triggered.

[0047] The early warning and shutdown module includes:

[0048] The early warning unit is used to remind operators to pay attention and take corresponding measures; when the AI ​​recognition module determines that the coal accumulation has reached the early warning threshold, the early warning system will remind operators to pay attention and take corresponding measures through sound and light alarms, text message notifications, etc.

[0049] Shutdown control unit: If the coal accumulation is serious and reaches the shutdown threshold, the shutdown control unit is used to cut off the power supply of the belt conveyor and stop the conveyor to prevent coal accumulation accidents.

[0050] The system management module includes:

[0051] The display unit provides a real-time system monitoring interface, displaying high-definition camera video, AI recognition results, warnings, shutdown status, and other information. Operators can understand the system's operating status in real time through the monitoring interface.

[0052] The data storage unit is used to store historical data, including the time, location, and handling of coal pile events. Operators can use the historical data query function to understand past coal pile events and handling situations in order to summarize lessons learned.

[0053] Example 2:

[0054] The belt conveyor coal pile protection system provided in Example 1 is further optimized. Specifically, Figure 2-Figure 3 As shown, the mounting frame includes a rotating arm 1, the lower end of the rotating arm 1 is rotatably connected to a rotating base 2, the lower end of the rotating base 2 is provided with a mounting plate 3 for installing a high-definition camera, the upper end of the rotating arm 1 is rotatably connected to a mounting base 4, the upper end of the mounting base 4 is fixedly connected to a connecting plate 5, and the top of the connecting plate 5 is provided with a clamping assembly 6.

[0055] It can be seen that the mounting plate 3 provided at the lower end of the rotating seat 2 facilitates the installation and fixation of the high-definition camera, and the rotating connection between the rotating arm 1 and the rotating seat 2, and the rotating connection between the rotating arm 1 and the mounting seat 4, enables the position of the high-definition camera to be adaptively adjusted according to the installation requirements or production environment, and the installation of the device and the beam or crossbar can be achieved through the connecting plate 5 and the clamping assembly 6 on the top of the mounting seat 4.

[0056] Example 3:

[0057] The belt conveyor coal pile protection system provided in Example 2 is further optimized. Specifically, Figure 5-Figure 6As shown, the clamping assembly 6 includes a second clamping plate 17 and a first clamping plate 14, a fixed extension plate 18 is transversely provided at the lower end of the second clamping plate 17, and the fixed extension plate 18 is fixedly connected to the connecting plate 5. A movable extension plate 13 is transversely provided at the middle part of the lower end of the clamping plate 14, and the lower end of the movable extension plate 13 is slidably connected to the connecting plate 5. In order to guide the sliding of the movable extension plate 13, a dovetail slide rail 16 is fixedly connected to the top of the connecting plate 5. The lower end of the movable extension plate 13 is slidably connected to the connecting plate 5 through the dovetail slide rail 16. The movable extension plate 13 is located on the fixed extension plate 1 At the inner position of 8, the end of the movable extension plate 13 away from the splint 14 extends to the outer side of the splint 2 17 away from the fixed extension plate 18. The side of the splint 2 17 away from the splint 14 is laterally fixedly connected to the limiting frame 19. The lower part of the limiting frame 19 is provided with a limiting cavity, and a return spring 20 is placed inside the limiting cavity. The end of the movable extension plate 13 away from the splint 14 is provided with a follower plate 15. The limiting frame 19 is plugged into the follower plate 15, and one end of the return spring 20 is in contact with the splint 2 17, and the other end of the return spring 20 is in contact with the follower plate 15.

[0058] With the above-mentioned structural design, when the mounting frame is fixed to the beam or crossbar through the clamping assembly 6, the clamping plate 14 is pulled to move in the direction away from the clamping plate 2 17, thereby increasing the distance between the clamping plate 14 and the clamping plate 2 17, so that the beam or crossbar can be placed between the clamping plate 14 and the clamping plate 2 17. In the process of pulling the clamping plate 14, the movable extension plate 13 drives the follower plate 15 to move, thereby squeezing the return spring 20 through the follower plate 15, so that the return spring 20 accumulates force. After loosening the clamping plate 14, the return spring 20 releases the accumulated force, pushing the follower plate 15 to drive the movable extension plate 13 and the clamping plate 14 to reset, and then the reset clamping plate 14 cooperates with the clamping plate 2 17 to clamp the beam or crossbar, thereby completing the fixation of the high-definition camera through the mounting frame.

[0059] Example 4:

[0060] The belt conveyor coal pile protection system provided in Example 2 is further optimized. Specifically, Figure 4 As shown, a rotating groove is provided at the upper end of the rotating arm 1, and the lower end of the mounting plate 3 extends into the rotating groove provided in the rotating arm 1. The inner wall of the rotating groove provided in the rotating arm 1 is embedded and fixedly connected with an insert 7. The mounting plate 3 is inserted into the rotating groove provided in the rotating arm 1 and is embedded and fixedly connected with an insert 4 11. The insert 1 7 and the insert 4 11 are rotatably connected by connecting bolts 2 12. A plurality of protrusions are provided in an annular array on one side of the insert 7 close to the insert 4 11, and a plurality of grooves are provided in an annular array on both sides of the insert 4 11. The protrusions on the side of the insert 7 are snap-fitted with the grooves provided on the side of the insert 4 11, and the number of grooves on the side of the insert 4 11 is twice the number of protrusions on the side of the insert 7.

[0061] Through the above structural design, it can be seen that when the rotating arm 1 rotates, the protrusion set on the side of the insert 1 7 engages with the groove opened on the side of the insert 4 11, thereby achieving the effect of positioning and limiting the rotation of the rotating arm 1.

[0062] Example 5:

[0063] The belt conveyor coal pile protection system provided in Example 2 is further optimized. Specifically, Figure 4 As shown, a rotating groove is provided on the upper part of the rotating seat 2, and the lower end of the rotating arm 1 extends into the rotating groove provided in the rotating seat 2. The inner wall of the rotating groove provided in the rotating seat 2 is embedded and fixedly connected with an insert three 9. The rotating arm 1 is inserted into the rotating groove provided in the rotating seat 2 and is embedded and fixedly connected with an insert two 8. The insert two 8 and the insert three 9 are rotatably connected by a connecting bolt one 10. A groove is provided on the side of the insert two 8, and a protrusion is provided on the side of the insert three 9. The insert three 9 is buckled with the groove provided on the side of the insert two 8 through the protrusion provided on the side. The number of grooves on the side of the insert two 8 is twice the number of protrusions on the side of the insert three 9.

[0064] Through the above structural design, it can be seen that when the rotating arm 1 or the rotating seat 2 rotates, the protrusion set on the side of the insert three 9 is engaged with the groove opened on the side of the insert two 8, so that the rotation of the rotating arm 1 or the rotating seat 2 can be positioned and limited.
