Description

Technical Field

[0001] This utility model relates to the field of train carriage water accumulation detection technology, and in particular to a train carriage water accumulation detection device. Background Technology

[0002] During the transportation of coal by rail freight, severe weather, precipitation, and other factors often lead to water accumulation inside the freight cars. This water accumulation not only increases safety hazards during transportation but also significantly impacts the quality measurement of coal.

[0003] The water accumulation inside trucks has significantly impacted coal quality measurement, mainly in the following aspects:

[0004] Inaccurate measurement: Water accumulation occupies space inside the car, reducing the actual amount of coal loaded. If this water factor is not taken into account during measurement, the result will be too high, affecting the accuracy of the data.

[0005] Quality Degradation: When water mixes with coal, it can increase the coal's moisture content and decrease its calorific value, thus affecting its performance. For steel producers, this directly impacts product quality and production efficiency.

[0006] Safety hazards: Accumulated water may also damage the structure and performance of trucks, increasing safety risks during transportation. Furthermore, impurities and pollutants in the water may cause secondary pollution to the coal. Utility Model Content

[0009] Preferably, the data transmission equipment includes an industrial switch and a fiber optic transceiver, and the data processing equipment includes a two-dimensional and three-dimensional image acquisition industrial control computer, an image workstation, and a client host.

[0010] Preferably, the longitudinal slider extends outward on one side and penetrates the insert frame. An elastic stop is rotatably connected to the surface of the extended part of the longitudinal slider. A sliding block is movably connected to the inner wall of the insert frame facing the inner wall of the elastic stop. Several spring rods are provided between the sliding block and the insert frame, as well as between the elastic stop and the longitudinal slider. One side of the sliding block overlaps with one side of the elastic stop.

[0011] Preferably, some of the transverse sliders are also movably mounted with limiting blocks embedded in the spring rods, and one side of the transverse slider is slidably connected to the surface of the extension of the longitudinal slider and the inclined surface of the elastic stop. One side of the transverse slider is also inserted into one edge of the sliding block. The inclined part of the limiting block is slidably connected to the edge of the insertion frame, and the vertical part overlaps with the outer wall of the insertion frame.

[0012] Preferably, a sliding frame is inserted into the top edge of the extension of the insertion frame, and a lifting frame located below the identification mechanism is inserted into one side of the sliding frame. An electric telescopic rod is connected between the insertion frame and the sliding frame, and between the sliding frame and the lifting frame.

[0013] Preferably, a rotary joint is installed on the upper surface of the lifting frame at the position of each identification mechanism. One end of the rotary joint is fixedly connected to a blower pipe, and a scraper is fixedly connected to the surface of the blower pipe. Both the blower pipe and the scraper are used to clean the lens of the identification mechanism. An air inlet pipe is provided on the upper surface of the lifting frame to connect several rotary joints.

[0014] Preferably, each of the lifting frames is rotatably connected to a sprocket near the bottom edge of each blower pipe. The sprockets are driven by a chain, and one of the sprockets is driven by a motor. The top of the sprocket extends outward through the lifting frame in the shape of a gear column and meshes with the bottom edge of the outer wall of the blower pipe.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the identification mechanism, using the high-speed linear array camera and three-dimensional image sensor in the identification mechanism, two-dimensional and three-dimensional images of the top of passing freight cars can be acquired. It innovatively integrates two-dimensional high-definition color image and three-dimensional image acquisition technology, focusing on capturing detailed information of the top of railway freight cars. Using advanced deep intelligent algorithms, the acquired image data is accurately analyzed, realizing the automatic identification and judgment of water accumulation on the top of freight cars.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figure 1-6As shown, a train carriage water accumulation detection device includes a slide rail 3 for fixing to the bottom edge of the transverse portion of a gantry erected beside the track. A lead screw 4 is rotatably connected to the bottom edge of the slide rail 3. A transverse slider 6, which is inserted into the bottom edge of the slide rail 3, is threaded onto the lead screw 4. A longitudinal slider 7, which is inserted into the top edge of the longitudinal portion of the gantry, is located near one end of the bottom edge of the slide rail 3. A frame 9 is engaged with the longitudinal slider 7, and the engaging surface of the longitudinal slider 7 is slidably connected to the transverse slider 6. The transverse slider 6 is engaged with the frame 9 and is used to move the frame 9 to directly above the track. The lead screw 4 is driven to rotate by a motor, thereby enabling the longitudinal slider 7 to be inserted into the top edge of the longitudinal portion of the gantry by manually climbing up the surface of the gantry. The device is then driven by the motor. The rotation of the lead screw 4 causes the horizontal slider 6 to move horizontally relative to the vertical slider 7. This allows the insertion frame 9, which is equipped with the identification mechanism 13, to first rise to the top edge of the gantry side by manually installing the vertical slider 7. Then, the horizontal slider 6 moves towards the vertical slider 7 until it alternates with the insertion frame 9, causing the insertion frame 9 to detach from the vertical slider 7 and be installed on the horizontal slider 6. Finally, as the horizontal slider 6 moves away from the vertical slider 7, it moves directly above the track. One side of the insertion frame 9 extends outward, and the bottom surface of the extension is threaded with several identification mechanisms 13. The identification mechanism 13 includes a high-speed linear array camera and a three-dimensional image sensor. The three-dimensional image sensor installed on the tower directly above the railway line collects three-dimensional images of the railway freight car.After data acquisition, the system will display a 3D image of the loading status on the top of the railway freight car. Inspection personnel can use this 3D image to automatically identify anomalies such as water accumulation, bulging of the freight car body, oversized tops, frozen coal under the car, foreign objects under the car, and excessive height of bulk cargo. A light shield 14 is installed on the lens of the high-speed line-scan camera to capture high-definition images of the freight car top. A 3D image sensor installed on the top of the slide rail 3 directly above the track captures the 3D model of the freight car. After data acquisition, the system will display a high-definition image of the freight car top and a 3D image of the car body. Inspection personnel can check the loading status of the freight cars through the system software and verify any anomalies by measurement. The system also includes a data transmission device 1 and a data processing device 2 installed on one side of the slide rail 3. The data transmission device 1 includes a... The equipment includes industrial switches, fiber optic transceivers, and data processing equipment 2, which includes a 2D and 3D image acquisition industrial control computer, an image workstation data publishing server, and a client host. The fiber optic transceiver in data transmission equipment 1 is deployed in the field equipment box and is responsible for data aggregation and conversion by the recognition mechanism 13. It is connected to the fiber optic transceiver and industrial switch deployed in the computer room through a fiber optic channel and is connected to the acquisition server in the computer room. The image workstation (data publishing server) integrates a high-performance CPU and GPU graphics card, mainly handling intelligent recognition work. The image recognition speed is less than 300ms / image, and it supports multi-threaded synchronous processing, with an equivalent recognition speed of 1 second / carriage (left, right, and top three views). The image acquisition industrial control computer and the vehicle body 3D image acquisition industrial control computer are devices for acquiring and storing vehicle passage records, vehicle passage images, and 3D images of trucks. They can store no less than 6 months of vehicle passage data.

[0029] In addition, in actual use, a top speed measuring unit sensor and a train arrival start module can be installed at the extension of the insertion frame 9. After the train arrival start module detects the arrival of the train, it automatically triggers the high-definition camera to start working. If no train arrival signal is detected for a continuous period of time (the time can be set, the default is 20 seconds), the system considers the entire train to have passed. Car number recognition host: The car number recognition module is divided into two parts. One part is the car number recognition antenna, which is installed and deployed in the middle of the track on site. The other part is the car number recognition host, which is installed and deployed in the front-end equipment box. Upon detecting the arrival of a freight car, the vehicle number recognition device identifies the freight car tag and, in conjunction with the cutting unit, displays the corresponding vehicle number on the system's freight car viewing interface for easy retrieval and archiving. The system can also connect to the railway pre-reporting system for automatic data matching, automatically generating freight car loading information while comparing the pre-reported vehicle number information with the vehicle number information collected by the vehicle number recognition module. This saves time for on-site vehicle number operators and improves operational efficiency. Furthermore, the installed 3D image sensor can not only detect the 3D image of the freight car's top using scanning technology but can also be installed on the side of the slide rail 3 or on the track to scan the cross-sectional outline of the car's undercarriage. By acquiring complete interface data of the carriage through the 3D image sensor and then integrating the 3D data, the system obtains... By analyzing the water accumulation area inside the carriages and utilizing the features of the 3D images of the carriage floor, the system can estimate the left-right and front-back deviations of the coal loading in fully loaded carriages, as well as the loading height and sinking height. Furthermore, when the recognition mechanism 13 is running, it can also use convolutional neural networks, deep learning algorithms, and machine vision texture feature extraction and frequency domain signal processing to identify and label cargo inspection issues in train images, maximizing the efficiency of on-site cargo inspection personnel. Currently implemented intelligent recognition functions include: tank car top cover opening, container top cover opening, foreign objects in open wagon sides, foreign objects in empty wagons, foreign objects on bulk cargo, foreign objects on container roofs, foreign objects on flat wagon roofs, foreign objects on tank car roofs, foreign objects on covered wagon roofs, unauthorized personnel climbing onto wagons, and coal water accumulation.

[0030] To facilitate the installation of the identification mechanism 13: The longitudinal slider 7 extends outwards on one side and penetrates the insert frame 9. An elastic stop 8 is rotatably connected to the surface of the extended portion of the longitudinal slider 7. A sliding block 17 is movably connected to the inner wall of the insert frame 9 facing the inner wall of the elastic stop 8. Several spring rods 18 are provided between the sliding block 17 and the insert frame 9, and between the elastic stop 8 and the longitudinal slider 7. One side of the sliding block 17 overlaps with one side of the elastic stop 8. A limiting block 5 is also movably installed on some of the transverse sliders 6 via spring rods 18. One side of the transverse slider 6 is slidably connected to the surface of the extended portion of the longitudinal slider 7 and the inclined surface of the elastic stop 8. One side of the transverse slider 6 is also inserted into one edge of the sliding block 17. The inclined portion of the limiting block 5 is slidably connected to the edge of the insert frame 9, and the vertical portion overlaps with the outer wall of the insert frame 9. Figure 4 and Figure 5As shown, by using the installed spring rod 18, it can be ensured that the sliding block 17 is in contact with the extension of the longitudinal slider 7 and that the vertical surface of the elastic stop 8 is in contact with the vertical surface of the side of the sliding block 17, thereby ensuring that the insert frame 9 is fixed on the longitudinal slider 7. When it is necessary to adjust the position of the insert frame 9, it can be combined with... Figure 6 The horizontal slider 6 only needs to slide until its rear plane is in contact with the front plane of the vertical slider 7, and slide until the left side of the horizontal slider 6 contacts the inclined surface of the elastic stop 8, forcing the elastic stop 8 to completely overcome the thrust of the spring rod 18 and retract into the vertical slider 7. Then, the horizontal slider 6 continues to slide until its left tip contacts the inclined surface of the right rear side of the slider 17, pushing the slider 17 to move against the thrust of the spring rod 18. As the horizontal slider 6 continues to move to the left, the limiting block 5 on its surface moves against the thrust of the spring rod 18 due to contact with the side of the insert frame 9. After the misalignment of 9, the limiting block 5 extends and resets, and its vertical surface is attached to the left side of the insert frame 9. At this time, the elastic stop 8 on the longitudinal slider 7 is retracted into the longitudinal slider 7 due to the pressure of the transverse slider 6, maintaining the misalignment state with the sliding block 17. Therefore, when the transverse slider 6 resets, the contact between the vertical surface of the limiting block 5 and the left side of the insert frame 9 can drive the insert frame 9 to move out of the longitudinal slider 7. When the insert frame 9 moves out of the longitudinal slider 7, its left side is interfered by the vertical surface of the limiting block 5 and cannot be disengaged, and its right side is interfered by the corner of the transverse slider 6 and cannot be disengaged, thus ensuring that the position of the insert frame 9 is fixed.

[0031] Further solutions to this embodiment, such as Figure 4 As shown, several electric telescopic rods 10 can also be installed on the left side of the insertion frame 9. When the identification mechanism 13 needs to be removed, the insertion frame 9 can be moved back to the extension of the longitudinal slider 7 by using the horizontal slider 6. Then, the electric telescopic rod 10 on the left side of the insertion frame 9 can be extended, and the telescopic end can be used to press the limiting block 5 to swing until it is misaligned with the insertion frame 9 and does not interfere with it. The horizontal slider 6 can then be pulled out smoothly, leaving the insertion frame 9 on the longitudinal slider 7. The elastic stop 8 on the longitudinal slider 7 will extend again because it is not squeezed by the horizontal slider 6 and will directly overlap and interfere with the right side of the limiting block 17.

[0032] To facilitate cleaning of the identification mechanism 13: a sliding frame 11 is inserted into the top edge of the extension of the insertion frame 9, and a lifting frame 12 located below the identification mechanism 13 is inserted into one side of the sliding frame 11. Electric telescopic rods 10 are connected between the insertion frame 9 and the sliding frame 11, and between the sliding frame 11 and the lifting frame 12. A rotary joint 21 is installed on the upper surface of the lifting frame 12 at the position of each identification mechanism 13. One end of the rotary joint 21 is fixedly connected to a blower pipe 19, and a scraper 20 is fixedly connected to the surface of the blower pipe 19. Both the blower pipe 19 and the scraper 20 are used to clean the lens of the identification mechanism 13. An air inlet pipe 15 is provided on the upper surface of the lifting frame 12 to connect several rotary joints 21. A sprocket 16 is rotatably connected to the bottom edge of the lifting frame 12 near each blower pipe 19. Several sprockets 16 are driven by chains, and one of the sprockets 16 is driven by a motor. The top of the sprocket 16 extends outward through the lifting frame 12 in a gear-like shape and meshes with the bottom edge of the outer wall of the blower pipe 19. In actual use, as... Figure 3 As shown, the bottom surface of the lifting frame 12 is provided with strip-shaped protrusions. These protrusions ensure that the chain connecting the sprocket 16 in the middle position does not disengage from the sprocket 16. This ensures that when one sprocket 16 rotates due to the motor's drive, it can drive the other sprockets 16 to rotate, thus rotating the gear-like columnar portion that passes through the lifting frame 12. In actual manufacturing, the bottom end of the outer wall of the blower pipe 19 can be machined into a toothed ring shape. The meshing of the toothed ring with the gear-like columnar portion allows the blower pipe 19 to rotate, thereby allowing the horizontal portion at the top edge of the blower pipe 19 to spray air onto the high-speed line-scan camera lens. The scraper 20 cleans the lens as the blower pipe 19 rotates. The rotating joint 21 ensures that the blower pipe 19 can rotate smoothly while the air inlet pipe 15 does not rotate, facilitating the connection of a fan and enabling air delivery into the blower pipe 19. After cleaning, refer to... Figure 4 and Figure 5 By extending the electric telescopic rod 10 on the sliding frame 11, the lifting frame 12 is lowered, allowing the blower pipe 19 to detach from the lens hood 14 at the high-speed line scan camera lens. Then, by extending the electric telescopic rod 10 at the extension of the insert frame 9, the sliding frame 11, under the connection of the vertical electric telescopic rod 10 on its surface, causes the lifting frame 12 to move the blower pipe 19 on its surface to be misaligned with the area directly below the lens hood 14, without affecting the image acquisition of the high-speed line scan camera.

[0033] Working principle: The insertion frame 9 is first installed on the longitudinal slider 7. Then, the longitudinal slider 7 is manually raised to the top position. Then, the screw 4 on the slide rail 3 rotates to move the transverse slider 6 towards the insertion frame 9 until it coincides with the longitudinal slider 7 and replaces the longitudinal slider 7 to engage with the insertion frame 9. The transverse slider 6 then moves and resets, causing the identification mechanism 13 on the surface of the insertion frame 9 to move directly above the track. In use, when the train arrival module detects the arrival of the train, it automatically triggers the high-speed line scan camera to start working. The high-speed line scan camera captures a high-definition line scan image of the train passing over the top, while simultaneously receiving the image segmentation unit signal and the train speed signal, automatically extracting high-definition images of each freight car. The system utilizes 3D image sensor scanning technology to detect 3D images of the truck's top. To facilitate operations for cargo inspectors, the system integrates 2D and 3D images. The 3D image sensor scans the cross-sectional outline of the truck's underside, acquiring complete interface data of the cargo compartment. This data is then transmitted via fiber optic network to a high-definition intelligent analysis unit for analysis and processing. The system automatically identifies vehicles with reinforcement issues and provides voice prompts to cargo inspectors to confirm their inspection. By integrating the 3D data, the system obtains the area of ​​water accumulation inside the cargo compartment. Furthermore, by utilizing the characteristics of the 3D underside image, the system can estimate the lateral and longitudinal deviations of the coal loading in a fully loaded cargo compartment, as well as the loading height and the depth of any sinking.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts for the motor, identification mechanism 13, industrial switch, fiber optic transceiver, 2D and 3D image acquisition industrial control computer, image workstation, and client host will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
