Description

Technical Field

[0001] This utility model relates to the field of measurement technology, specifically to an online measurement device for coal yard material storage. Background Technology

[0002] In industries such as coal production, power generation, and chemicals that rely on coal as a raw material or energy source, accurate measurement and dynamic monitoring of coal yard materials are core aspects of production scheduling, cost accounting, and resource management. Online measurement equipment for coal yard materials, as a key measuring device, is required to efficiently detect parameters such as the volume and mass of bulk coal piles, providing data support for enterprise operational decisions. The principle of online measurement equipment for coal yard materials is to collect three-dimensional spatial data of coal piles using laser spatial detection technology, calculate the coal pile volume through geometric modeling and algorithms, and then convert the mass into mass based on coal density, thus achieving the measurement of inventory parameters. However, existing online measurement equipment for coal yard materials still has certain shortcomings in its use. For example, the track-type coal tumbler with self-cleaning function proposed in application number CN202320072468.6 includes a track, a traveling trolley suspended below the track, a rotating platform at the bottom of the traveling trolley, a laser scanner at the bottom of the rotating platform, and symmetrically arranged purging devices on both sides of the traveling trolley. A drive motor controls the traveling trolley to move back and forth along the track, while a micro-pump provides purging gas. The outlet of the micro-pump is connected to the inlet through a guide pipe, allowing the gas to be discharged from the purging nozzle, thus removing coal from the concave guide rail and the rotating mechanism of the rotating platform. The dust is blown off, and the rotating gimbal controls the rotation of the laser scanner as the equipment reaches different positions to collect coal pile data. A micro air pump is used to blow away the track and rotating mechanism, which improves the accuracy of the coal inventory and the measurement accuracy. In actual use, the internal environment of the coal yard is complex, and there are often a lot of floating objects and dust in the air. These floating objects are easy to adhere to the surface of the laser scanner. However, this coal inventory only has a structure for blowing away the track and does not include a cleaning structure for the laser scanner. As a result, the adhering floating objects and dust will affect the measurement effect and reduce the effectiveness of use.

[0003] Therefore, we propose an online measurement device for coal yard material storage to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an online measurement device for coal yard material storage, so as to solve the problem mentioned in the background art that it is inconvenient to clean the laser scanner, which affects the measurement effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online measurement device for coal yard material storage, comprising a mounting plate and a laser scanner, wherein a servo motor is mounted on the bottom of the mounting plate, a connecting plate is connected to the shaft end of the servo motor, and connecting seats are mounted on the bottom of both ends of the connecting plate, and the inner bottom of the connecting seats is connected to the laser scanner. The connector is equipped with a cleaning drive mechanism. The bottom of the cleaning drive mechanism is connected to an active blowing mechanism to clean the dust on the surface of the laser scanner.

[0006] Preferably, the mounting plate has symmetrical through holes at both ends, and the mounting plate is fixedly connected to the top of the coal shed by screws passing through the through holes during installation.

[0007] The above-mentioned structural design uses screws through through holes to fix the mounting plate to the top of the coal shed. The installation method is reliable and can ensure the overall stability of the equipment. At the same time, the detachable connection facilitates the maintenance and disassembly of the equipment in the future. It is adaptable to different mounting planes on the top of the coal shed and provides basic support for the stable operation of the laser scanner.

[0008] Preferably, the cleaning drive mechanism includes a second servo motor mounted on the top of the right-side connecting seat. The shaft end of the second servo motor is connected to a drive screw. The left end of the drive screw is rotatably connected to the left-side connecting seat. A linkage seat is sleeved on the outer ring of the drive screw. When the drive screw rotates, it drives the linkage seat to move.

[0009] Preferably, the cleaning drive mechanism further includes slides fixedly installed at both ends of the linkage seat, with a limit rod passing through the interior of the slide, and positioning seats fixedly sleeved at both ends of the limit rod. The positioning seats are fixedly connected to the connecting seat, and the slide is slidably connected to the limit rod.

[0010] With the above-mentioned structure, the servo motor drives the screw to rotate, which can drive the linkage seat to move along the screw axis, thereby realizing the reciprocating movement adjustment of the active blowing mechanism. This design allows the blowing mechanism to cover the entire surface of the laser scanner, avoiding blind spots and improving the comprehensiveness of cleaning. Moreover, the driving method is precise and controllable, meeting the needs of different cleaning paths. The sliding engagement between the slide block and the limit rod provides guidance and limitation for the movement of the linkage seat, preventing the linkage seat from shifting or shaking during movement, and improving the accuracy and reliability of the cleaning action.

[0011] Preferably, the active purging mechanism includes a fixed frame fixedly installed on the surface of the connecting seat on the left side, a filter screen is fitted inside the left end of the fixed frame, a bracket is fixedly installed on the inner ring of the fixed frame, a drive motor is fixedly installed in the middle of the bracket, and a fan blade assembly is fixedly installed on the shaft end of the drive motor.

[0012] Preferably, the active purging mechanism further includes a delivery pipe symmetrically installed on the right end of the fixed frame. The output end of the delivery pipe is fixedly connected to a telescopic pipe, and the output end of the telescopic pipe is fixedly connected to a flow divider. The flow divider has a hollow structure, and the top of the flow divider is fixedly connected to the bottom end of the slide. Nozzles are installed at equal angles on the inner ring of the flow divider.

[0013] With the above-mentioned structure, the drive motor drives the fan blade assembly to rotate and generate airflow. The filter screen can filter impurities and dust in the airflow to avoid secondary contamination of the laser scanner surface during cleaning. The bracket provides a stable mounting base for the drive motor and fan blade assembly, ensuring the stability of airflow generation. The filtered airflow ensures efficient cleaning and reduces the impact of dust on the accuracy of laser scanning. The delivery pipe delivers clean airflow to the telescopic pipe, whose length can be adjusted to match the movement range of the linkage seat, ensuring the continuity of airflow delivery. The hollow structure of the diverter seat enables uniform distribution of airflow, and the nozzles installed at equal angles can evenly spray airflow onto the surface of the laser scanner, removing coal dust adhering to the surface and ensuring unobstructed scanning optical path.

[0014] Preferably, a clamping connection mechanism is installed on the top surface of the mounting plate. The clamping connection mechanism includes a fixed seat fixedly installed on the left end of the top surface of the mounting plate. An adjusting screw is threaded through the internal thread of the fixed seat. A rotating shaft seat is installed on the right end of the adjusting screw. A movable clamping plate is connected to the right end of the rotating shaft seat. The adjusting screw is rotatably connected to the movable clamping plate through the rotating shaft seat. Limiting rails are fixedly installed on both sides of the bottom of the fixed seat. The bottom of the movable clamping plate is slidably connected to the limiting rails. A fixed clamping plate is fixedly connected to the right end of the limiting rails. The bottom surface of the fixed clamping plate is fixedly connected to the top surface of the mounting plate. Anti-slip pads are installed on the inner sides of both the movable clamping plate and the fixed clamping plate.

[0015] With the above-mentioned structural design, rotating the adjusting screw can drive the movable clamping plate to slide along the limiting track, which cooperates with the fixed clamping plate to clamp and fix the installation carrier. It is suitable for installation structures of different widths, expands the installation and adaptation range of the equipment and the ease of disassembly and assembly. The anti-slip pad can increase the friction of the clamping surface, prevent the equipment from loosening or shifting after installation, and avoid excessive clamping force from damaging the installation carrier, further improving the stability of the equipment installation and ensuring the stable operation of the laser scanner in complex coal yard environments.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the online measurement device for coal yard material storage; 1. By combining the cleaning drive mechanism and the active blowing mechanism, the problem of inconvenient surface cleaning of laser scanners is effectively solved. The servo motor drives the screw to move the linkage seat back and forth. Combined with the guide and limit of the slide and the limit rod, the blowing mechanism can fully cover the surface of the laser scanner and avoid cleaning blind spots. In the active blowing mechanism, the filter screen filters airflow impurities to prevent secondary pollution. The flow divider and the equal angle nozzle realize uniform airflow spray, which can efficiently remove surface dust, ensure unobstructed scanning optical path, and improve measurement effect. 2. The mounting plate is fixed by screws through the through holes, ensuring a reliable connection and facilitating disassembly and maintenance later. The clamping connection mechanism can drive the movable clamping plate to slide by adjusting the screw, adapting to different widths of mounting carriers. Anti-slip pads and limit rails further enhance the stability of the installation and prevent the equipment from loosening or shifting. The structural design of each component is adapted to provide a stable installation foundation for the laser scanner and can adapt to complex coal yard environments, ensuring the continuous and stable operation of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: an online measurement device for coal yard material storage, including a mounting plate 1 and a laser scanner 5. A servo motor 2 is installed at the bottom of the mounting plate 1. A connecting plate 3 is connected to the shaft end of the servo motor 2. Connecting seats 4 are installed at the bottom of both ends of the connecting plate 3. The inner side of the bottom of the connecting seat 4 is connected to the laser scanner 5. Through holes are symmetrically opened at both ends of the mounting plate 1. When the mounting plate 1 is installed, it is fixedly connected to the top of the coal shed by screws passing through the through holes. In the above-mentioned structural design, the mounting plate 1 serves as the basic load-bearing component of the equipment. Through the symmetrical through holes at both ends, screws are inserted through the through holes to fix the mounting plate 1 to the top of the coal shed, providing a stable installation support for the entire equipment. The servo motor 2 installed at the bottom of the mounting plate 1 serves as the rotation drive source, and its shaft end is connected to the connecting plate 3. When the servo motor 2 starts, it can drive the connecting plate 3 to rotate around the shaft end of the servo motor 2. The connecting seats 4 installed at the bottom of both ends of the connecting plate 3 serve as the connection and fixation function. The inner side of its bottom is connected to the laser scanner 5. Therefore, the rotation of the connecting plate 3 will synchronously drive the connecting seats 4 and the laser scanner 5 to adjust their angles, so that the laser scanner 5 can flexibly adjust the scanning direction and expand the scanning coverage of the coal yard materials. The laser scanner 5 emits a laser beam to irradiate the surface of the coal yard material. When the laser beam encounters the material, it is reflected. The scanner receives the reflected laser signal and calculates the distance between the scanner and each point on the material surface using the time difference or phase difference of laser propagation. Combined with its own scanning angle information, it finally constructs three-dimensional morphological data of the coal yard material, realizing online measurement of the material storage status.

[0021] The cleaning drive mechanism is installed inside the connecting seat 4. The cleaning drive mechanism includes a servo motor 6 installed on the top of the right connecting seat 4. The shaft end of the servo motor 6 is connected to a drive screw 7. The left end of the drive screw 7 is rotatably connected to the left connecting seat 4. The outer ring of the drive screw 7 is fitted with a linkage seat 8. When the drive screw 7 rotates, it drives the linkage seat 8 to move. The cleaning drive mechanism also includes a slide seat 9 fixedly installed at both ends of the linkage seat 8. A limit rod 10 passes through the inside of the slide seat 9. Positioning seats 11 are fixedly fitted at both ends of the limit rod 10. The positioning seats 11 are fixedly connected to the connecting seat 4. The slide seat 9 is slidably connected to the limit rod 10. In the above-described structure, the servo motor 6, mounted on the top of the right-side connecting seat 4, serves as the drive source. Its shaft is connected to the drive screw 7. When the servo motor 6 starts, it drives the drive screw 7 to rotate synchronously. The left end of the drive screw 7 is rotatably connected to the left-side connecting seat 4. This connection method provides support for the stable rotation of the drive screw 7. The outer ring of the drive screw 7 is fitted with a linkage seat 8. During the rotation of the drive screw 7, the linkage seat 8 is driven to move along the axial direction of the drive screw 7 through the threaded transmission. At the same time, the slide seats 9, which are fixedly installed at both ends of the linkage seat 8, move together with the linkage seat 8. Since the sliding seat 9 has a limit rod 10 running through it, and the two ends of the limit rod 10 are fixedly connected to the connecting seat 4 through the positioning seat 11, the sliding seat 9 and the limit rod 10 form a sliding fit, thereby providing guidance and limiting for the movement of the linkage seat 8, preventing the linkage seat 8 from shifting or shaking during the movement, and ensuring the smoothness of its movement.

[0022] The bottom of the cleaning drive mechanism is connected to an active blowing mechanism to clean the dust on the surface of the laser scanner 5. The active blowing mechanism includes a fixed frame 12 fixedly installed on the surface of the left connecting seat 4. A filter screen 13 is fitted inside the left end of the fixed frame 12. A bracket 14 is fixedly installed on the inner ring of the fixed frame 12. A drive motor 15 is fixedly installed in the middle of the bracket 14. A fan blade assembly 16 is fixedly installed on the shaft end of the drive motor 15. The active blowing mechanism also includes a conveying pipe 17 symmetrically installed on the right end of the fixed frame 12. A telescopic pipe 18 is fixedly connected to the output end of the conveying pipe 17. A diverter seat 19 is fixedly connected to the output end of the telescopic pipe 18. The diverter seat 19 has a hollow structure. The top of the diverter seat 19 is fixedly connected to the bottom end of the slide 9. Nozzles 20 are installed at equal angles on the inner ring of the diverter seat 19. The above structure design provides a mounting base for the entire purging mechanism with the fixed frame 12 fixedly installed on the surface of the left connecting seat 4. The filter screen 13 installed inside the left end can filter the incoming air and intercept impurities and dust in the air. The bracket 14 in the inner ring of the fixed frame 12 is used to stably support the drive motor 15 in the middle. When the drive motor 15 starts, the fan blade group 16 fixed at its shaft end rotates synchronously, thereby generating airflow. The airflow is filtered by the filter screen 13 to form clean airflow. Clean airflow is delivered to telescopic tube 18 via delivery pipe 17 symmetrically installed at the right end of fixed frame 12. Telescopic tube 18 can extend and retract in length as slide 9 moves, ensuring the continuity of airflow delivery. The diverter 19 connected to the output end of telescopic tube 18 has a hollow structure, which can receive and temporarily store airflow. Since the top of diverter 19 is fixedly connected to the bottom of slide 9, it will move with slide 9. The nozzles 20 installed at equal angles on the inner ring of diverter 19 evenly spray the temporarily stored clean airflow onto the surface of laser scanner 5, thereby cleaning the dust attached to its surface and ensuring that the scanning effect of laser scanner 5 is not affected by dust.

[0023] Example 2: Based on Example 1, this utility model adopts the following... Figure 6-7 The technical solution shown further discloses that a clamping connection mechanism is installed on the top surface of the mounting plate 1. The clamping connection mechanism includes a fixed seat 21 fixedly installed on the left end of the top surface of the mounting plate 1. An adjusting screw 22 is threaded through the inside of the fixed seat 21. A rotating shaft seat 23 is installed on the right end of the adjusting screw 22. A movable clamping plate 24 is connected to the right end of the rotating shaft seat 23. The adjusting screw 22 is rotatably connected to the movable clamping plate 24 through the rotating shaft seat 23. Limiting rails 25 are fixedly installed on both sides of the bottom of the fixed seat 21. The bottom of the movable clamping plate 24 is slidably connected to the limiting rails 25. A fixed clamping plate 26 is fixedly connected to the right end of the limiting rails 25. The bottom surface of the fixed clamping plate 26 is fixedly connected to the top surface of the mounting plate 1. Anti-slip pads 27 are installed on the inner sides of both the movable clamping plate 24 and the fixed clamping plate 26. The above structure design uses a fixed base 21, which is fixedly installed on the left side of the top surface of the mounting plate 1, to provide the mounting foundation for the entire mechanism. The adjusting screw 22, which has a thread running through it, can move axially by rotation. The rotating shaft seat 23 installed on the right end of the adjusting screw 22 serves as a connection and reversing function, so that when the adjusting screw 22 rotates, it can only push the movable clamping plate 24 connected to the right end to move horizontally, without driving the movable clamping plate 24 to rotate synchronously. The limiting rails 25 fixedly installed on both sides of the bottom of the fixed base 21 provide sliding guidance for the movable clamping plate 24. The bottom of the movable clamping plate 24 is slidably connected to the limiting rails 25 to ensure that the movable clamping plate 24 moves stably along a straight line under the push of the adjusting screw 22. The fixed clamping plate 26, which is fixedly connected to the right end of the limiting rail 25, is fixed to the top surface of the mounting plate 1 to form a clamping fixed end. When the movable clamping plate 24 moves closer to the fixed clamping plate 26, the two cooperate to clamp and fix the mounting carrier. The anti-slip pads 27 installed on the inner sides of the movable clamping plate 24 and the fixed clamping plate 26 can increase the friction between them and the mounting carrier, prevent the equipment from loosening and shifting after clamping, and avoid excessive clamping force from damaging the mounting carrier, thereby improving the stability of the installation.
