[0035] like Figure 1-Figure 5 As shown, the present invention provides a fixed coal panning device for a bulk cargo yard, comprising: a scanning mechanism 1, an encoding mechanism 3, a pan-tilt mechanism 4, and a mounting frame 6. The scanning mechanism 1 is used to scan the coal in the yard and obtain the volume of the coal pile. A scanning device fixing mechanism 2 is installed on the top of the scanning mechanism 1. The provided scanning device fixing mechanism 2 is used to facilitate the installation of the scanning mechanism 1 and to facilitate the connection of the line of the scanning mechanism 1 to the external interface. The encoding mechanism 3 is used to convert and transfer transmission data. The encoding mechanism 3 is installed above the scanning device fixing mechanism 2, and the scanning mechanism 1 and the scanning device fixing mechanism 2 transmit data to each other. The signal obtained by the scanning mechanism 1, such as a bit stream or data, is compiled and converted into a signal form that can be used for communication, transmission, and storage, and then transmitted to the upper end device by wired and / or wireless means to perform three-mode modeling of the coal pile, thereby obtaining information about the coal pile by analyzing the model. The pan-tilt mechanism 4 is used to transmit data and adjust the scanning angle of the scanning mechanism 1. The pan-tilt mechanism 4 is installed on the top of the encoding mechanism 3. The pan-tilt mechanism 4 drives the encoding mechanism 3 to rotate, thereby causing the connected scanning mechanism 1 to rotate accordingly, so as to achieve all-round, no-dead-angle scanning, and the encoding mechanism 3 limits the rotation angle of the pan-tilt mechanism 4 through the encoder data. The encoding mechanism 3 and the pan-tilt mechanism 4 complement each other. At the same time, the pan-tilt mechanism 4 transmits the acquired data to the digital platform in a wired or / and wireless manner, and performs three-dimensional modeling, volume measurement, and motion control through the logic algorithm in the digital platform. The encoding mechanism 3 and the pan-tilt mechanism 4 are connected by an integrated cable 5 to realize wired transmission of data and reduce interference. The mounting frame 6 is used to support and suspend the entire coal pan meter. The mounting frame 6 is installed on the top of the pan-tilt mechanism 4, so that the entire equipment is installed on the top of the shed in the bulk yard.

[0036] The specific logic is as follows: Multiple laser coal counting meters are installed atop each greenhouse, covering the coal yard. This allows for comprehensive, seamless coal counting in a short period of time. Combined with laser scanners on both sides of the bucket wheel excavator, this technology achieves an accuracy of 0.5%. This creates a real-time, dynamic digital stockpile. After the operation is complete, the digital yard measures the volume of the outflowing stockpile in real time and sends it to the production management system for intelligent analysis. Any discrepancies between the stockpile volume and weight and the operation instructions are immediately reported, further strengthening the supervision of freight quality.

[0037] The Digital Stockyard System consists of two parts: the Digital Stockyard Display System and the Digital Stockyard Coal Counting System. The Digital Stockyard Display System primarily creates 3D models of the main structures and production equipment within the stockyard greenhouse. The stockyard coal pile model is a fusion of real-time laser scanning of bucket wheel excavators and modeling of the coal counting system. The Digital Stockyard Coal Counting System utilizes a fixed coal counting instrument to achieve full stockyard coverage, rapid response, zero blind spots, and real-time dynamic 3D scanning imaging.

[0038] Real-time coal counting technology: Collects data from the entire coal pile within 5 minutes and quickly builds a 3D model of the stockpile. It can operate 24 hours a day, with a relative measurement accuracy of less than 5‰.

[0039] Multiple modeling technology: the bucket wheel excavator's two-dimensional laser scanner performs real-time modeling, and the coal counting meter performs regular modeling to form a fused digital stockyard model that can be reused for the bucket wheel excavator's intelligent control and real-time coal counting.

[0040] In some embodiments, the scanning mechanism 1 of the present invention includes a scanner 101. A rotatable signal contact 102 is mounted at the end of the scanner 101 for transmitting and receiving signals. A motor drives the signal contact 102 to rotate, thereby increasing the detection range. The outer surfaces of the signal contact 102 are covered with an inner protective cover 103 and an outer protective cover 105, respectively, to protect the signal contact 102 and prevent dust, enabling the entire device to be used in harsh coal yard environments. A feedback port 104 is provided on the inner protective cover 103 to further concentrate the signal from the signal contact 102 and reduce external interference.

[0041] In some embodiments, the scanner 101 of the present invention is a German SICK brand LD-LRS3611 laser scanner, and its specific parameters are as follows:

[0042]

[0043] In some embodiments, the scanning device mounting mechanism 2 of the present invention includes a scanner mounting bracket 201, which facilitates the installation of the scanner 101. A junction box 202 is provided on the scanner mounting bracket 201. The junction box 202 is connected to the scanner 101 and provides power and signal cables for the scanner 101. After the scanner 101 is mounted and fixed on the scanner mounting bracket 201, external devices can be connected to the scanner 101 via connectors on the junction box 202, enabling power supply and information exchange with the scanner 101.

[0044] In some embodiments, a heat sink 203 is installed on the top of the scanner mounting bracket 201 of the present invention. The heat sink 203 is located on the side of the junction box 202. The device generates heat during continuous use. Therefore, the installation of the heat sink 203 on the top of the scanner mounting bracket 201 increases the top surface area of ​​the scanner mounting bracket 201 and improves the heat dissipation efficiency of the scanner 101.

[0045] In some embodiments, the encoding mechanism 3 of the present invention includes an encoder mounting bracket 301 and an encoder 302. The encoder mounting bracket 301 is bolted to the top of the scanner fixture 2, connecting the upper and lower parts. The encoder 302 is installed between the scanner fixture 2 and the encoder mounting bracket 301. The encoder 302 is connected to the junction box 202, thereby transmitting signals or data from the scanner 101 to the encoder 302. The encoder 302 then converts the signals or data into signals that can be used for communication, transmission, and storage. After receiving the readable data, the platform processes the data from the scanner 101 to form data that can be visually displayed.

[0046] A data connector 303 is provided on the side of the encoder 302, and the data connector 303 is connected to the integrated cable 5. The data connector 303 is mainly a waterproof connector to improve the adaptability of the device in harsh environments.

[0047] In some embodiments, the pan-tilt mechanism 4 of the present invention includes a digital pan-tilt platform 401, which is connected to the integrated cable 5, receives information data from the encoder 302, and transmits the information data to the digital platform in a wired and / or wireless manner. An executive servo 402 is provided on the side of the digital pan-tilt platform 401, and a rotary shaft 403 is provided at the bottom of the digital pan-tilt platform 401, and the rotary shaft 403 is driven by the executive servo 402. When the executive servo 402 receives a command to start, it can drive the rotary shaft 403 to rotate to adjust the direction of the scanner 101, and the rotary shaft 403 is connected to the top of the encoder mounting bracket 301 through a coupling.

[0048] In some embodiments, the integrated cable 5 of the present invention includes multiple cables connected to the power and signal of the encoder 302 and the power signal of the scanner 101, thereby achieving integrated circuits and improving the convenience of installation and maintenance. A shielding layer can be provided inside the integrated cable 5 to further improve anti-interference capabilities.

[0049] In some embodiments, the present invention utilizes multiple fixed coal panning devices in bulk cargo yards, each of which is suspended above the coal pile. This improves the panning device's coverage, allowing for more accurate model coordinate information and faster, more accurate, and more comprehensive information feedback.

[0050] The specific use process of the utility model is as follows: the entire device is suspended on the ceiling of the storage yard through the mounting frame 6;

[0051] Set the inspection interval of the pan / tilt mechanism 4 and the scanning interval of the scanning mechanism 1;

[0052] The scanning mechanism 1 scans the coal pile in the yard and transmits the data to the encoding mechanism 3, which converts the data into a communication signal readable by the upper device and then transmits it to the pan / tilt mechanism 4;

[0053] The pan-tilt mechanism 4 transmits the acquired data to the data platform in real time. The data platform performs three-dimensional modeling of the coal pile in the yard based on the acquired data and measures the volume of the material pile.

[0054] In summary, the fixed coal pan meter device for bulk cargo yards of the present invention scans the coal pile by setting a scanning mechanism 1 above the bulk cargo yard, thereby obtaining the coordinate points and height occupied by the coal pile, and transmitting the obtained data to the encoding mechanism 3 to be converted into signals that can be used for communication, transmission and storage, and finally transmitted to the computer in real time through the pan-tilt mechanism 4 for three-dimensional modeling and mapping of the material pile volume, thereby achieving the effect of obtaining coal pile information in real time.

[0055] By providing a signal contact head 102 and driving the signal contact head 102 to rotate by a motor, the detection range of the scanner 101 can be increased during surveying and mapping, and a patrol effect can be achieved through the cyclic movement of the signal contact head 102;

[0056] At the same time, the servo 402 drives the rotary shaft 403 to enable the scanner 101 to rotate in a circle, thereby achieving full coverage of the yard, rapid response, no measurement blind spots, and real-time dynamic three-dimensional scanning and imaging.

[0057] Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
