Description

Technical Field

[0001] This utility model relates to the technical field of vehicle blocking devices, specifically to an intelligent identification and linkage vehicle blocking device for exhaust emissions from coal transport vehicles. Background Technology

[0002] Coal transport lines, as core channels for land-based coal transportation (such as the highway lines supporting the Datong-Qinhuangdao Railway in Shanxi and the coal collection and distribution station connecting lines in Inner Mongolia), undertake the majority of the country's coal transportation tasks, with an average of over 50,000 heavy-duty diesel trucks passing through daily. These vehicles suffer from severe emissions problems due to prolonged high-load operation, rapid engine aging, and some owners' unauthorized modifications to emission systems to reduce costs.

[0003] Existing intelligent exhaust gas identification and linkage vehicle blocking devices use multiple types of sensors deployed at key sections of coal transport lines (such as entrances, ramps, and weighing stations) to collect the physical characteristics and chemical composition of vehicle exhaust gas in real time. They also associate this data with vehicle identification information to provide raw data for subsequent judgment. Through the collaboration of an edge computing unit (deployed locally at the detection point) and a cloud-based monitoring platform, the collected "exhaust gas data + vehicle data" are analyzed in real time, thresholds are compared, and exceedances are determined. This avoids misjudgments due to single data anomalies and generates vehicle blocking commands.

[0004] Traditional barrier gates typically use a separate horizontal bar to intercept passing vehicles. To improve the interception effect, the horizontal bar is set to be relatively long, and the weight of the long bar is concentrated at the end. Since the stress points of the long bar are concentrated on the rotating shaft, a huge torque is generated when rotating, which can easily lead to overload damage to the rotating shaft and motor. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an intelligent identification and linkage vehicle blocking device for exhaust emissions from coal transport vehicles. The second barrier gate and the fixed frame are hinged together by a second connecting plate, which will cause the second barrier gate to fold inward around the rotation point of the mounting frame towards the first barrier gate. Ultimately, the first and second barriers gates are parallel to each other and perpendicular to the ground, thereby reducing the space occupied by the barrier gate and improving the adaptability of the equipment. Under the connection of the threaded sleeve and the screw, the pressure on the rotating shaft of the first barrier gate can be reduced.

[0006] The objective of this utility model is achieved through the following technical solution: The intelligent exhaust emission identification and linkage vehicle blocking device for coal transport vehicles includes a protective box; it also includes a first barrier and a support assembly rotatably mounted at the rear end of the protective box; a threaded sleeve is rotatably mounted at the rear end of the protective box, a screw is threadedly connected to the inner wall of the threaded sleeve, a connecting block is rotatably mounted at the other end of the screw, and a fixing frame is rotatably mounted on the outer side of the connecting block; a mounting frame is fixedly connected to the end of the first barrier away from the protective box, a second barrier is rotatably mounted on the inner wall of the mounting frame, a first connecting plate is fixedly connected to the lower end of the fixing frame, the first connecting plate is rotatably mounted on the outer wall of the first barrier, a second connecting plate is hinged between the fixing frame and the second barrier, and the support assembly is located at the lower end of the second barrier.

[0007] In one optional embodiment, a self-locking motor is fixedly connected to the inner wall of the protective box, and the first barrier gate is fixedly connected to the output end of the self-locking motor. The self-locking motor is used to drive the first barrier gate to rotate.

[0008] In one optional embodiment, a controller is fixedly connected to the bottom of the inner wall of the protective box, a base plate is fixedly connected to the lower end of the protective box, and a support rod is fixedly connected to the upper edge of the base plate.

[0009] In one optional embodiment, a display panel is fixedly connected to the upper end of the support rod, the display panel is tilted, a camera is fixedly connected to the upper end of the display panel, and two supplementary lights are symmetrically arranged at the lower end of the support rod.

[0010] In one alternative implementation, the controller is electrically connected to a self-locking motor, a display panel, a camera, and a fill light.

[0011] In one optional embodiment, the support assembly includes a detachable mounting block disposed at the lower end of the second barrier and a support plate rotatably disposed on the inner wall of the mounting block. The upper surface of the support plate is arc-shaped, and the side surface of the support plate is in contact with the inner wall surface of the mounting block.

[0012] In one optional embodiment, the support assembly further includes a first groove formed at the lower end of the support plate, a buffer pad slidably disposed on the inner wall of the first groove, a damper and a spring fixed between the buffer pad and the top of the inner wall of the first groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The second barrier gate and the fixed frame are hinged together by the second connecting plate, which will cause the second barrier gate to fold inward around the rotation point of the mounting frame towards the inside of the first barrier gate. Ultimately, the first and second barrier gates are parallel to each other and perpendicular to the ground, thereby improving the adaptability of the equipment. The second connecting plate provides the second barrier gate with an independent and optimized movement trajectory, allowing the second barrier gate to fold at a large angle, thereby reducing the space occupied by the barrier. Under the connection of the threaded sleeve and the screw, the pressure on the rotation shaft of the first barrier gate can be reduced. By rotating the threaded sleeve, its length can be easily adjusted.

[0014] 2. By rotating the support plate towards the inner wall of the mounting block under gravity until the side of the support plate is in contact with the inner wall of the mounting block, the support plate can be perpendicular to the ground. When the second gate is fully opened, the buffer pad will collide with the ground and compress the damper and spring upward, thereby reducing the impact force on the equipment. Then, with the support of the support plate, the load on the rotating shaft of the self-locking motor in the standby state can be reduced, thereby increasing the service life of the equipment.

[0021] Please refer to Figures 1-5This utility model provides an embodiment of an intelligent identification and linkage vehicle blocking device for exhaust emissions from coal transport vehicles, including a protective box 1; it also includes a first barrier 101 rotatably disposed at the rear end of the protective box 1 and a support assembly; a threaded sleeve 102 is rotatably disposed at the rear end of the protective box 1, a screw 103 is threadedly connected to the inner wall of the threaded sleeve 102, a connecting block 104 is rotatably disposed at the other end of the screw 103, a fixing frame 105 is rotatably disposed on the outer side of the connecting block 104, a mounting frame 106 is fixedly connected to the end of the first barrier 101 away from the protective box 1, a second barrier 107 is rotatably disposed on the inner wall of the mounting frame 106, a first connecting plate 108 is fixedly connected to the lower end of the fixing frame 105, the first connecting plate 108 is rotatably disposed on the outer wall of the first barrier 101, a second connecting plate 109 is hinged between the fixing frame 105 and the second barrier 107, and the support assembly is disposed at the lower end of the second barrier 107. The first barrier 101 is rotated by a self-locking motor 2. The movement causes the threaded sleeve 102 to lift upwards together. Since the rotation points of the first barrier 101 and the threaded sleeve 102 are at different positions, and the lengths of the threaded sleeve 102 and the screw 103 are fixed, the screw 103 will push the fixed frame 105 to rotate during rotation. Since the second barrier 107 is hinged to the fixed frame 105 through the second connecting plate 109, the second barrier 107 will be driven to fold inwards around the rotation point of the mounting frame 106 towards the first barrier 101. Ultimately, the first barrier 101 and the second barrier 107 are parallel to each other and perpendicular to the ground, facilitating vehicle passage. Under the connection of the threaded sleeve 102 and the screw 103, the pressure on the rotating shaft of the first barrier 101 can be reduced, solving the problem that the crossbar is too long, the weight of the long bar is concentrated at the end, and since the force points of the long bar are concentrated on the rotating shaft, a huge torque will be generated during rotation, which can easily lead to overload damage to the rotating shaft and motor.

[0022] Please refer to Figures 1-4 In a preferred embodiment of this utility model, a self-locking motor 2 is fixedly connected to the inner wall of the protective box 1. The first barrier gate 101 is fixedly connected to the output end of the self-locking motor 2. The self-locking motor 2 is used to drive the first barrier gate 101 to rotate. A controller 3 is fixedly connected to the bottom end of the inner wall of the protective box 1. A base plate 4 is fixedly connected to the lower end of the protective box 1. A support rod 5 is fixedly connected to the upper edge of the base plate 4. A display panel 6 is fixedly connected to the upper end of the support rod 5. The display panel 6 is inclined. A camera collector 7 is fixedly connected to the upper end of the display panel 6. Two supplementary devices are symmetrically arranged at the lower end of the support rod 5. The light 8, controller 3, self-locking motor 2, display panel 6, camera 7, and supplementary light 8 are electrically connected. The camera 7 collects vehicle license plates and compares them with the license plate information stored in the controller 3 to determine whether the vehicle can pass through the coal transportation line. This ensures that only vehicles with compliant exhaust emissions can pass through the gate to enter the coal transportation line, which not only improves the air quality of the coal transportation line but also indirectly prevents harmful exhaust gases from spreading into the industrial and residential areas, effectively protecting the health of employees.

[0023] Please refer to Figure 1 and Figure 5 In a preferred embodiment of this utility model, the support assembly includes a detachable mounting block 201 disposed at the lower end of the second barrier gate 107 and a support plate 202 rotatably disposed on the inner wall of the mounting block 201. The upper surface of the support plate 202 is arc-shaped, and the side surface of the support plate 202 is in contact with the inner wall of the mounting block 201. The support assembly also includes a first groove 203 opened at the lower end of the support plate 202, a buffer pad 204 slidably disposed on the inner wall of the first groove 203, and a damper 205 fixed between the buffer pad 204 and the top of the inner wall of the first groove 203. During the unfolding process, the support plate 202 rotates towards the inner wall of the mounting block 201 under the action of gravity until the side of the support plate 202 is in contact with the inner wall of the mounting block 201, so that the support plate 202 can be perpendicular to the ground. When the second gate 107 is fully unfolded, the buffer pad 204 will collide with the ground and compress the damper 205 and the spring 206 upward, thereby reducing the impact force on the equipment. Then, under the support of the support plate 202, the load on the rotating shaft of the self-locking motor 2 in the standby state can be reduced, thereby increasing the service life of the equipment.

[0024] In use, the information of all coal-hauling vehicles that meet the exhaust emission standards is first entered into the controller 3 for storage. Then, when the transport vehicle passes through the coal transport line entrance, the camera 7 collects the vehicle license plate information and compares it with the license plate information stored in the controller 3 to determine whether the vehicle can pass through the coal transport line.

[0025] When comparing vehicle information, the specific information will be displayed on the display panel 6 to facilitate driver verification and prevent the camera 7 from erroneously collecting information, which could prevent the vehicle from passing. If the vehicle information comparison fails, staff will be notified to manually test the exhaust emissions. If the emissions meet the standards, the vehicle will be allowed to pass through the gate. This ensures that only vehicles with compliant exhaust emissions can enter the coal transportation line. This not only improves the air quality of the coal transportation line but also indirectly prevents harmful exhaust gases from spreading into the industrial and residential areas, effectively protecting the health of employees. Once the license plate is successfully matched with the internally stored information, the controller 3 starts the self-locking motor 2, causing the self-locking motor 2 to rotate the first barrier 101 and lift the threaded sleeve 102 upwards. Since the rotation points of the first barrier 101 and the threaded sleeve 102 are different, and the lengths of the threaded sleeve 102 and the screw 103 are fixed, the screw 103 will push the fixing frame 105 to rotate during rotation. Since the second barrier 107 is hinged to the fixing frame 105 through the second connecting plate 109, the second barrier 107 will fold inwards around the rotation point of the mounting frame 106 towards the first barrier 101, ultimately making the first barrier 101 and the second barrier 107 parallel to each other and perpendicular to the ground, facilitating vehicle passage. After the vehicle passes, the controller 3 controls the self-locking motor 2 to rotate in the opposite direction, so that the first barrier 101 and the second barrier 107 return to their original state. During the unfolding process, the support plate 202 rotates towards the inner wall of the mounting block 201 under the action of gravity until the side of the support plate 202 is in contact with the inner wall of the mounting block 201, so that the support plate 202 can be perpendicular to the ground. When the second barrier 107 is fully unfolded, the buffer pad 204 will collide with the ground and compress the damper 205 and the spring 206 upward, thereby reducing the impact force on the equipment. Then, under the support of the support plate 202, the load on the rotating shaft of the self-locking motor 2 in the standby state can be reduced, thereby increasing the service life of the equipment.

[0026] Through the above steps, the self-locking motor 2 drives the first barrier 101 to rotate and lifts the threaded sleeve 102 upwards. Since the rotation points of the first barrier 101 and the threaded sleeve 102 are different, and the lengths of the threaded sleeve 102 and the screw 103 are fixed, the screw 103 will push the fixed frame 105 to rotate during rotation. Since the second barrier 107 is hinged to the fixed frame 105 through the second connecting plate 109, the second barrier 107 will be driven to fold inwards around the rotation point of the mounting frame 106 towards the first barrier 101. Finally, the first barrier 101 and the second barrier 107 are parallel to each other and perpendicular to the ground, facilitating vehicle passage. Under the connection of the threaded sleeve 102 and the screw 103, the pressure on the rotating shaft of the first barrier 101 can be reduced, solving the problem that the crossbar is too long, the weight of the long bar is concentrated at the end, and since the force points of the long bar are concentrated on the rotating shaft, a huge torque will be generated during rotation, which can easily lead to overload damage to the rotating shaft and motor.

[0027] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0028] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
