Description

Technical Field

[0001] This utility model is a rapid sensing device for vehicles in green channels, belonging to the field of green channel vehicle sensing. Background Technology

[0002] Currently, when inspecting green channel vehicles at highway toll booths, manual inspections are not conducted because manual inspections cannot determine whether the vehicle is carrying mixed cargo or whether the cargo compartment contains other products or equipment.

[0003] Therefore, many existing highway tollbooths use X-ray vehicle inspection devices to inspect vehicles for green channel access. These devices emit X-rays to see through vehicles and quickly determine whether they are green channel vehicles.

[0004] However, although using X-ray vehicle inspection equipment for green channel inspection is highly efficient, the X-rays emitted by the equipment can have an impact on the environment or the surrounding public when there are no vehicles entering and under unobstructed lighting conditions, which is not conducive to safe use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fast sensing device for green channel vehicles.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A rapid sensing device for green channel vehicles includes a sensor housing mounted on a bracket. The sensor housing has an infrared sensor mounted on it and a rain / snow shielding mechanism that cooperates with the infrared sensor. The bracket includes a movable base and a fixed base. The sensor housing is placed on top of the movable base. A vertical rod is provided on each side of the bottom of the movable base, and the vertical rod is inserted into the fixed base. A cylinder is mounted on the fixed base, and the top output end of the cylinder is connected and fixed to the bottom of the movable base.

[0008] Furthermore, the rain and snow shielding mechanism includes two sets of support blocks fixed on both sides of the top of the sensor housing and a fixing frame fixed in the middle of both sides of the sensor housing. The top of the support block is provided with a sliding column, and the top outer surface of the fixing frame is provided with a through hole. A sliding hole is provided on one side of the through hole, extending to the outer side surface of the fixing frame. A positioning element is slidably connected inside the sliding hole.

[0009] Furthermore, the positioning component includes a positioning plate slidably connected in the sliding hole, one end of the positioning plate extending through to the outside of the fixing frame and connected and fixed to the protrusion, the outer surface of the protrusion being provided with a traction rope, and the bottom side of the fixing frame being provided with a winding post that cooperates with the traction rope.

[0010] Furthermore, a slider is provided on each side of the outer surface of the positioning plate, and a groove is provided on the inner wall of the through hole to cooperate with the slider. A spring is provided between the inner wall of one side of the groove and the slider.

[0011] Furthermore, the rain and snow shielding mechanism also includes a top plate located at the top of the sensor housing. A baffle is hinged to each of the two sides of the top plate. A sliding groove that cooperates with the sliding column is opened on the bottom side of the baffle. A vertical plate is fixed to the outer surface of the other two sides of the top plate. A number of positioning holes are opened vertically at equal intervals on the outer surface of the vertical plate. The vertical plate is inserted into the through hole, and the end of the positioning plate passes through the positioning hole.

[0012] Furthermore, a shielding component is provided between the top plate and the baffle. The shielding component includes a storage groove formed on one side of the top of the top plate. A winding shaft is movably connected in the storage groove. A coil spring is provided between the winding shaft and the inner wall of the storage groove. A shielding cloth is wound on the outer surface of the winding shaft. The end of the shielding cloth passes through the top plate and is connected and fixed to the baffle.

[0013] Furthermore, the bracket is positioned at the entrance of the highway toll station on the same side as the X-ray vehicle inspection device.

[0014] The beneficial effects of this utility model are:

[0015] By designing an infrared sensor, when a green channel vehicle enters the green channel of the toll station, the infrared sensor detects the vehicle's entry and sends a signal to the controller of the X-ray vehicle inspection device. The X-ray vehicle inspection device then activates, using X-rays to inspect the vehicle's cargo compartment and determine if it is a green channel vehicle. Once the rear of the vehicle leaves the sensing range of the infrared sensor, the sensor detects the vehicle's departure and sends another signal to the controller of the X-ray vehicle inspection device, causing the device to stop operating. This design avoids the impact of X-rays on the environment or the surrounding public under untreated conditions, while also reducing the operating time of the X-ray vehicle inspection device and extending its service life.

[0016] Through the design of the rain and snow shielding mechanism, rainwater and snow falling from the sky will fall on the infrared sensor during rainy and snowy weather, thus not interfering with or affecting the normal operation of the infrared sensor. At the same time, it reduces the corrosion of the infrared sensor by external debris.

[0017] The design of the rain and snow shielding mechanism allows the tilt angle of the two baffles to be adjusted according to the amount of rain or snow or the wind direction, thus adapting the two baffles to different environmental conditions. At the same time, by changing the tilt angle of the baffles, the snow and dust deposited on the baffles can be quickly cleared.

[0018] The design of the positioning component allows for quick positioning of the vertical plate. When positioning is required, pulling the traction rope moves the positioning plate, causing it to disengage from the positioning hole on the vertical plate and releasing the restriction between the fixing frame and the vertical plate. Then, the end of the traction rope is wound around the winding post at the bottom of the fixing frame to complete the positioning of the positioning plate. At this point, the height of the top plate can be adjusted, thereby adjusting the angle and extension length of the baffle.

[0019] By designing the shielding component, the angle of the baffle can be adjusted, and the shielding cloth can also be used to shield the hinge of the top plate and the baffle, thereby achieving a water-proof effect. This prevents rain and snow from dripping onto the sensor housing from the hinge of the top plate and the baffle. At the same time, elastic sealing gaskets can be set at both ends of the hinge of the top plate and the baffle to achieve a sealing effect at the ends. Attached Figure Description

[0028] 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.

[0029] Please see Figures 1-6This utility model provides a technical solution for a rapid sensing device for vehicles in a green channel, including a sensor housing 1, which is mounted on a bracket 19. An infrared sensor 2 is mounted on the sensor housing 1, and a rain / snow shielding mechanism is provided on the sensor housing 1 to cooperate with the infrared sensor 2. The bracket 19 includes a movable base 21 and a fixed base 22. The sensor housing 1 is placed on top of the movable base 21. A vertical rod is provided on each side of the bottom of the movable base 21, and the vertical rod is inserted into the fixed base 22. A cylinder 23 is mounted on the fixed base 22, and the top output end of the cylinder 23 is connected and fixed to the bottom of the movable base 21. The bracket 1... 9 is set at the entrance of the highway toll station on the same side as the X-ray vehicle inspection device 20. The X-ray vehicle inspection device 20 is an existing technology, such as the same-side three-source three-view X-ray vehicle inspection device disclosed in Chinese Patent No. 202122382336.7 or the dual X-ray source green channel vehicle rapid inspection device disclosed in Chinese Patent No. 202121668982.3. Therefore, it is not described in detail. Through the design of the bracket 19, the cylinder 23 can push the moving seat 21 to move vertically. The moving seat 21 will drive the sensor housing 1 and the infrared sensor 2 to move vertically, so that the infrared sensor 2 can be adapted to different vehicle models.

[0030] See Figures 3-5 The rain and snow shielding mechanism includes two sets of support blocks 3 fixed to the top two sides of the sensor housing 1 and a fixing frame 10 fixed to the middle of the two sides of the sensor housing 1. The top of the support block 3 is provided with a sliding column 4. The top outer surface of the fixing frame 10 is provided with a through hole. A sliding hole is provided on one side of the through hole, extending to the outer side surface of the fixing frame 10. A positioning element 11 is slidably connected inside the sliding hole. The rain and snow shielding mechanism also includes a top plate 5 located at the top of the sensor housing 1. A baffle 6 is hinged to each side of the top plate 5. A sliding groove 7 that cooperates with the sliding column 4 is provided on the bottom side of the baffle 6. A vertical plate 8 is fixed to the outer surface of the other two sides of the top plate 5. The outer surface of the device has several vertically spaced positioning holes 9. The vertical plate 8 is inserted into the through hole, and the end of the positioning plate 12 extends into the positioning hole 9. Through the design of the rain and snow shielding mechanism, in rainy or snowy weather, rainwater and snow falling from the sky will fall on the infrared sensor 2, thus not interfering with or affecting the normal operation of the infrared sensor 2. At the same time, it reduces the erosion of the infrared sensor 2 by external debris. In addition, the tilt angle of the two baffles 6 can be adjusted according to the size of the rain and snow or the wind direction, so that the two baffles 6 can be adapted to different environmental conditions. At the same time, by changing the tilt angle of the baffles 6, the snow and dust deposited on the baffles 6 can be quickly cleaned.

[0031] See Figure 6 The positioning component 11 includes a positioning plate 12 slidably connected within the sliding hole. One end of the positioning plate 12 extends through to the outside of the fixing frame 10 and is connected and fixed to the protrusion 15. A traction rope 16 is provided on the outer surface of the protrusion 15. A winding post cooperating with the traction rope 16 is provided on one side of the bottom of the fixing frame 10. A slider 13 is provided on each side of the outer surface of the positioning plate 12. A groove cooperating with the slider 13 is opened on the inner wall of the through hole. A groove is provided between the inner wall of one side of the groove and the slider 13. Spring 14; through the design of positioning component 11, the vertical plate 8 can be quickly limited. When the limitation is required, pull the traction rope 16, and the traction rope 16 will drive the positioning plate 12 to move, thereby causing the positioning plate 12 to disengage from the positioning hole 9 on the vertical plate 8, releasing the limitation between the fixing frame 10 and the vertical plate 8. Then, the end of the traction rope 16 is wrapped around the winding post at the bottom of the fixing frame 10 to complete the limitation of the positioning plate 12. At this time, the height of the top plate 5 can be adjusted, thereby realizing the adjustment of the angle and extension length of the baffle 6.

[0032] See Figure 5 A shielding component is provided between the top plate 5 and the baffle 6. The shielding component includes a storage groove on one side of the top of the top plate 5. A winding shaft 17 is movably connected in the storage groove. A coil spring is provided between the winding shaft 17 and the inner wall of the storage groove. A shielding cloth 18 is wound on the outer surface of the winding shaft 17. The end of the shielding cloth 18 passes through the top plate 5 and is fixedly connected to the baffle 6. Through the design of the shielding component, while satisfying the angle adjustment of the baffle 6, the shielding cloth 18 can also shield the hinge of the top plate 5 and the baffle 6, thereby achieving a water-proof effect. This prevents rain and snow from dripping onto the sensor housing 1 from the hinge of the top plate 5 and the baffle 6. At the same time, elastic sealing gaskets can be set at both ends of the hinge of the top plate 5 and the baffle 6 to achieve the end sealing effect.

[0033] In operation, when a green channel vehicle enters the green channel of the toll station, the infrared sensor 2 detects the vehicle's entry and sends a signal to the controller of the X-ray vehicle inspection device 20. The X-ray vehicle inspection device 20 then activates, using X-rays to inspect the vehicle's cargo compartment and determine its authenticity. Once the rear of the vehicle leaves the sensing range of the infrared sensor 2, it sends another signal to the controller, stopping the X-ray vehicle inspection device 20. This avoids the impact of X-rays on the environment or the surrounding public under open-air conditions, reduces the operating time of the X-ray vehicle inspection device 20, and extends its lifespan. In rainy or snowy weather, falling rain and snow will fall on the infrared sensor 2, preventing interference with its normal operation and reducing the risk of external debris erosion. Furthermore, the rain and snow provide shade and protection. The mechanism can adjust the tilt angle of the two baffles 6 according to the amount of rain or snow, or the wind direction, so that the two baffles 6 can be adapted to different environmental conditions. At the same time, by changing the tilt angle of the baffles 6, the snow and dust deposited on the baffles 6 can be quickly cleared. That is, by pulling the traction rope 16, the traction rope 16 moves the positioning plate 12, thereby disengaging the positioning plate 12 from the positioning hole 9 on the vertical plate 8, releasing the limitation between the fixing frame 10 and the vertical plate 8. Then, the end of the traction rope 16 is wrapped around the fixing frame. The positioning plate 12 can be limited on the winding column at the bottom of 10. At this time, the height of the top plate 5 can be adjusted, thereby adjusting the angle and extension length of the baffle 6. While satisfying the angle adjustment of the baffle 6, the hinge of the top plate 5 and the baffle 6 can also be blocked by the shielding cloth 18, thereby achieving the effect of water prevention, so that rain and snow from the outside will not drip onto the sensor housing 1 along the hinge of the top plate 5 and the baffle 6. At the same time, elastic sealing gaskets can be set at both ends of the hinge of the top plate 5 and the baffle 6 to achieve the end sealing effect.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
