At the same time, there is no way to protect the camera in case of bad weather. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a self-patrolling device for highway traffic condition detection, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A self-patrolling device for highway traffic condition detection, including a fixed frame. A square rod is fixedly installed on the left side of the fixed frame. A solar panel is fixedly installed on the top of the square rod. A flat rod is slidably installed on the left side of the square rod. A camera is rotatably installed on the top left side of the flat rod. A protection mechanism is arranged on the surface of the square rod; Among them, the protection mechanism includes a sliding plate, a collection basket, a semi-circular block, an arrow column, a long column and a baffle. The sliding plate is slidably installed on the surface of the square rod. The collection basket is fixedly installed on the side of the sliding plate away from the square rod. The bottom of the collection basket is a sliding plate. The semi-circular block is fixedly installed at the bottom of the sliding plate. The arrow column is fixedly installed on the top of the fixed frame. The long column is fixedly installed at the bottom of the sliding plate. The baffle is fixedly installed on the left side of the square rod. Among them, a support mechanism for supporting the baffle and a prevention mechanism for preventing the baffle from breaking are provided on the surface of the square rod. At the same time, when the collection basket continues to move downward, the semi-circular block at the bottom of the collection basket will contact the arrow column. When the semi-circular block contacts the arrow column, the bottom of the collection basket will be opened, causing the snow pile above to fall.

[0007] According to the above technical solution, the protection mechanism further includes a triangular inclined block, a push block and a semi-cylinder. The triangular inclined block is slidably installed on the top of the baffle. The push block is fixedly installed on the left side of the triangular inclined block. The semi-cylinder is fixedly installed on the top of the baffle. Therefore, the push block will collide with the semi-cylinder. When the push block collides with the semi-cylinder, solids such as broken ice hanging at the bottom of the baffle will fall.

[0008] According to the above technical solution, the push block contacts the semi-cylinder, the long column contacts the triangular inclined block, the semi-circular block contacts the arrow column. A first spring is provided between the two semi-circular blocks. When the semi-circular block leaves the arrow column, the spring between the semi-circular blocks will pull the semi-circular blocks towards the middle to close.

[0009] According to the above technical solution, the support mechanism includes an elastic telescopic rod, a U-shaped rod, a long strip plate, a fixed block, a rotating column, a support rod and an elastic telescopic block. The fixed end of the elastic telescopic rod is fixedly installed at the bottom of the sliding plate. The U-shaped rod is fixedly installed at the free end of the elastic telescopic rod. One end of the long strip plate is fixedly installed at the bottom of the U-shaped rod. A tooth groove is opened on the surface of the other end of the long strip plate away from the square rod. The fixed block is fixedly installed on the front of the fixed frame. The rotating column is rotatably installed on the front of the fixed block. A tooth groove is opened on the circumferential surface of the end of the rotating column away from the fixed frame. The fixed end of the elastic telescopic block is slidably installed on the left side of the square rod. The support rod is fixedly installed at the free end of the elastic telescopic block. The Z-shaped rod is slidably installed at the bottom of the support rod. A tooth groove is opened on the surface of the bottom of the Z-shaped rod close to the square rod. The bottom of the front of the square plate is rotatably installed on the side of the Z-shaped rod close to the square rod. The triangular block is fixedly installed on the front of the square rod. When the U-shaped rod moves downward, it will drive the long strip plate to move downward. When the long strip plate moves downward, it will drive the rotating column on the fixed block to rotate. When the rotating column rotates, the screw on the fixed frame will be further tightened.

[0010] According to the above technical solution, the support mechanism further includes a Z-shaped rod, a square plate, and a triangular block. A tooth groove is formed on one side of the bottom of the Z-shaped rod close to the square rod. The bottom of the front surface of the square plate is rotatably installed on one side of the Z-shaped rod close to the square rod. The triangular block is fixedly installed on the front surface of the square rod. Since the square plate is rotatably installed on the Z-shaped rod in one direction, the square plate will move outwards when it contacts the triangular block.

[0011] According to the above technical solution, the tooth groove of the rotating column meshes with the tooth groove of the long strip plate, the tooth groove of the Z-shaped rod meshes with the tooth groove of the rotating column, and the square plate contacts the triangular block. When the long strip plate moves downwards, it will drive the rotating column on the fixed block to rotate. When the rotating column rotates, it will further tighten the screw on the fixed frame.

[0012] According to the above technical solution, the prevention mechanism includes a connecting block, an elastic telescopic square rod, a telescopic rotating rod, an elastic telescopic giant rod, a bottom plate, a limiting plate, and a connecting rod. One side of the connecting block is fixedly installed on the front surface of the support rod. The fixed end of the elastic telescopic square rod is fixedly installed at the other end of the connecting block. The bottom plate is fixedly installed at the free end of the elastic telescopic square rod. The fixed end of the elastic telescopic giant rod is fixedly installed at the bottom of the square rod. The free end of the elastic telescopic giant rod is fixedly connected to the bottom plate. The telescopic rotating rod is rotatably installed on the left side of the square rod. The elastic telescopic square rod is rotatably connected to the telescopic rotating rod. When the elastic telescopic square rod moves downwards, it will drive the telescopic rotating rod to move. When the telescopic rotating rod moves, a platform will be formed due to rotation to lift the elastic telescopic block.

[0013] According to the above technical solution, the telescopic rotating rod contacts the elastic telescopic block, and the limiting plate contacts the connecting rod. When the connecting rod moves, it will squeeze the limiting plate. When the limiting plate is squeezed, it will slide towards the direction close to the fixed frame.

[0014] The present invention provides a self-patrolling device for detecting highway traffic conditions. It has the following beneficial effects: (1) In this invention, when the push block collides with the semi-cylinder, solids such as broken ice hanging at the bottom of the baffle will fall off, avoiding the obstruction of the camera's line of sight by the ice cubes. When the triangular inclined block is pushed, it will drive the push block to move. When the push block moves, it will push off the accumulated snowflakes on the baffle, reducing the possibility of icing, thereby prolonging the service life of the baffle. At the same time, it can avoid the obstruction of the camera's field of view caused by icing, and also avoid the structural deformation or damage caused by excessive weight, which may affect the subsequent work.

[0015] (2) In this invention, when the rotating column rotates, it will further tighten the screws on the fixing bracket, preventing the screws from loosening due to the long-term placement of the device. When the Z-shaped rod moves, it will drive the support rod to move, and at the same time, the elastic telescopic block will also push the support rod, thereby supporting the baffle, effectively enhancing its stability, minimizing deformation or damage caused by external forces, and also buffering external forces to a certain extent, reducing the risk of fracture, thus improving the reliability of the system.

[0016] (3) In this invention, when the telescopic rotating rod moves, a platform will be formed due to rotation to support the elastic telescopic block, preventing objects above from falling. When the limit plate leaves, the limit on the flat rod will be released. When the limit on the flat rod is released, the flat rod will move downward, preventing the baffle above from damaging the camera, providing additional buffer space for the camera to avoid direct collision, and also effectively isolating the vibration generated by fractures above, ensuring that the camera can work stably, effectively extending its service life, and reducing the replacement cost of the equipment.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 8 , an embodiment of the present invention is: A self-inspecting device for highway traffic condition detection, including a fixed frame 1, a square rod 4 is fixedly installed on the left side of the fixed frame 1, a solar panel 3 is fixedly installed on the top of the square rod 4, a flat rod 8 is slidably installed on the left side of the square rod 4, a camera 2 is rotatably installed on the top left of the flat rod 8, and a protection mechanism is arranged on the surface of the square rod 4; Among them, the protection mechanism includes a sliding plate 501, a collection basket 502, a semi-circular block 503, an arrow post 504, a long post 505 and a baffle 506. The sliding plate 501 is slidably installed on the surface of the square rod 4, the collection basket 502 is fixedly installed on the side of the sliding plate 501 away from the square rod 4, the bottom of the collection basket 502 is a sliding plate, the semi-circular block 503 is fixedly installed on the bottom of the sliding plate, the arrow post 504 is fixedly installed on the top of the fixed frame 1, the long post 505 is fixedly installed on the bottom of the sliding plate 501, and the baffle 506 is fixedly installed on the left side of the square rod 4, reducing the possibility of icing, thereby extending the service life of the baffle 506, and at the same time avoiding the obstruction of the camera 2's field of view caused by icing, and also avoiding structural deformation or damage caused by overweight, which affects subsequent work.

[0021] The protection mechanism further includes a triangular inclined block 507, a push block 508 and a semi-cylinder 509. The triangular inclined block 507 is slidably mounted on the top of the baffle 506. The push block 508 is fixedly mounted on the left side of the triangular inclined block 507. The semi-cylinder 509 is fixedly mounted on the top of the baffle 506. Therefore, the push block 508 will collide with the semi-cylinder 509. When the push block 508 collides with the semi-cylinder 509, solids such as broken ice hanging at the bottom of the baffle 506 will fall off.

[0022] The push block 508 contacts the semi-cylinder 509, the long column 505 contacts the triangular inclined block 507, the semi-arc block 503 contacts the arrow column 504. A first spring is arranged between the two semi-arc blocks 503. When the semi-arc block 503 leaves the arrow column 504, the spring between the semi-arc blocks 503 will pull the semi-arc blocks 503 towards the middle to close.

[0023] During the operation of this embodiment: Fix the fixing frame 1 at a specified position. Fix the square rod 4 on the top of the fixing frame 1. At the same time, slidably mount the flat rod 8 on the square rod 4. Mount the camera 2 on the top of the flat rod 8. Place the solar panel 3 on the top of the square rod 4. When it snows, the snowflakes will fall into the interior of the collection basket 502. At the same time, the baffle 506 will also block the snowflakes floating towards the camera 2. When the snowflakes in the collection basket 502 become more and more, it will press the collection basket 502 to move downward. When the collection basket 502 moves downward, it will drive the sliding plate 501 to move downward. When the sliding plate 501 moves downward, it will drive the long column 505 to move downward. When the long column 505 moves downward, it will contact and squeeze the triangular inclined block 507. When the long column 505 squeezes the triangular inclined block 507, it will push the triangular inclined block 507. When the triangular inclined block 507 is pushed, it will drive the push block 508 to move. When the push block 508 moves, it will push off the accumulated snowflakes on the baffle 506. However, since the bottom of the snowflakes may freeze into ice and affect the shooting of the camera 2 below, the push block 508 will collide with the semi-cylinder 509. When the push block 508 collides with the semi-cylinder 509, solids such as broken ice hanging at the bottom of the baffle 506 will fall off. At the same time, when the collection basket 502 continues to move downward, the semi-arc block 503 at the bottom of the collection basket 502 will contact the arrow column 504. After the semi-arc block 503 contacts the arrow column 504, it will open the bottom of the collection basket 502, causing the snow pile above to fall.

[0024] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, a support mechanism for supporting the baffle 506 and a prevention mechanism for preventing the baffle 506 from breaking are provided on the surface of the square rod 4. The support mechanism includes an elastic telescopic rod 601, a U-shaped rod 602, a long strip plate 603, a fixing block 604, a rotating column 605, a support rod 609, and an elastic telescopic block 610. The fixed end of the elastic telescopic rod 601 is fixedly installed at the bottom of the sliding plate 501, the U-shaped rod 602 is fixedly installed at the free end of the elastic telescopic rod 601, one end of the long strip plate 603 is fixedly installed at the bottom of the U-shaped rod 602, and a tooth groove is provided on the surface of the other end of the long strip plate 603 away from the square rod 4. The fixing block 604 is fixedly installed on the front surface of the fixing frame 1, the rotating column 605 is rotatably installed on the front surface of the fixing block 604, and a tooth groove is provided on the circumferential surface of the end of the rotating column 605 away from the fixing frame 1. The fixed end of the elastic telescopic block 610 is slidably installed on the left side of the square rod 4, the support rod 609 is fixedly installed at the free end of the elastic telescopic block 610, the Z-shaped rod 606 is slidably installed at the bottom of the support rod 609, and a tooth groove is provided on the surface of the bottom of the Z-shaped rod 606 close to the square rod 4. The bottom of the front surface of the square plate 607 is rotatably installed on the surface of the Z-shaped rod 606 close to the square rod 4, and the triangular block 608 is fixedly installed on the front surface of the square rod 4, which can effectively enhance its stability, minimize deformation or damage caused by external forces, and at the same time buffer external forces to a certain extent and reduce the risk of fracture, thereby improving the reliability of the system.

[0025] The support mechanism further includes a Z-shaped rod 606, a square plate 607, and a triangular block 608. A tooth groove is provided on the surface of the bottom of the Z-shaped rod 606 close to the square rod 4. The bottom of the front surface of the square plate 607 is rotatably installed on the surface of the Z-shaped rod 606 close to the square rod 4, and the triangular block 608 is fixedly installed on the front surface of the square rod 4. Since the square plate 607 is rotatably installed on the Z-shaped rod 606 in one direction, when the square plate 607 contacts the triangular block 608, the square plate 607 will move outward.

[0026] The tooth groove of the rotating column 605 meshes with the tooth groove of the long strip plate 603, the tooth groove of the Z-shaped rod 606 meshes with the tooth groove of the rotating column 605, and the square plate 607 contacts the triangular block 608. When the long strip plate 603 moves downward, it will drive the rotating column 605 on the fixing block 604 to rotate. When the rotating column 605 rotates, the screw on the fixing frame 1 will be further tightened.

[0027] The prevention mechanism includes a connecting block 701, an elastic telescopic square rod 702, a telescopic rotating rod 703, an elastic telescopic giant rod 704, a bottom plate 705, a limit plate 706 and a connecting rod 707. One side of the connecting block 701 is fixedly mounted on the front side of the support rod 609, the fixed end of the elastic telescopic square rod 702 is fixedly mounted on the other end of the connecting block 701, the bottom plate 705 is fixedly mounted on the free end of the elastic telescopic square rod 702, the fixed end of the elastic telescopic giant rod 704 is fixedly mounted on the bottom of the square rod 4, the free end of the elastic telescopic giant rod 704 is fixedly connected to the bottom plate 705, the telescopic rotating rod 703 is rotatably mounted on the left side of the square rod 4, and the elastic telescopic square rod 702 is rotatably connected to the telescopic rotating rod 703, which can provide additional buffer space for the camera 2 to avoid direct collision, and can also effectively isolate the vibration caused by the fracture above, ensure that the camera 2 can work stably, effectively extend its service life, and reduce the replacement cost of the equipment.

[0028] The telescopic rotating rod 703 contacts the elastic telescopic block 610 , and the limit plate 706 contacts the connecting rod 707 . When the connecting rod 707 moves, it squeezes the limit plate 706 . When the limit plate 706 is squeezed, it slides toward the direction close to the fixing frame 1 .

[0029] When this embodiment works: when the sliding plate 501 moves, the elastic telescopic rod 601 is compressed downwards; when the elastic telescopic rod 601 is slowly compressed, a certain pressure is applied downwards; when the elastic telescopic rod 601 applies pressure downwards, the U rod 602 is driven to move downwards; when the U rod 602 moves downwards, the long strip 603 is driven to move downwards; when the long strip 603 moves downwards, the rotating column 605 on the fixed block 604 is driven to rotate; when the rotating column 605 rotates, the screws on the fixed frame 1 are further tightened; when the rotating column 605 rotates, the Z-shaped rod 606 is driven to move; when the Z-shaped rod 606 moves, the support rod 609 is driven to move; When the upper baffle 506 is broken, it will press downward. When the support rod 609 is squeezed, it will drive the Z-shaped rod 606 to move downward. When the Z-shaped rod 606 moves downward, it will drive the square plate 607 to move downward. However, because the square plate 607 is installed on the Z-shaped rod 606 for one-way rotation, when the square plate 607 contacts the triangular block 608, it will move the square plate 607 outward. When the square plate 607 moves outward, it will drive the Z-shaped rod 606 to move outward. When the Z-shaped rod 606 moves outward, it will break away from the contact with the rotating column 605 to avoid loosening the screw.

[0030] When the baffle 506 breaks, it will drive the support rod 609 to move. When the support rod 609 moves, it will drive the connecting block 701 to move. When the connecting block 701 moves, it will squeeze the elastic telescopic square rod 702. When the elastic telescopic square rod 702 is squeezed, it will move downward. When the elastic telescopic square rod 702 moves downward, it will drive the telescopic rotating rod 703 to move. When the telescopic rotating rod 703 moves, a platform will be formed due to rotation to lift the elastic telescopic block 610. At the same time, when the elastic telescopic square rod 702 moves, it will drive the connecting rod 707 to move. When the connecting rod 707 moves, it will squeeze the limiting plate 706. When the limiting plate 706 is squeezed, it will slide towards the direction close to the fixed frame 1. When the limiting plate 706 leaves, the limitation on the flat rod 8 will be released. When the limitation on the flat rod 8 is released, the flat rod 8 will move downward to prevent the upper baffle 506 from damaging the camera 2. When the flat rod 8 moves downward, it will contact the bottom plate 705. When the bottom plate 705 is squeezed, it will first move downward, and at the same time, the force of the telescopic rotating rod 703 will be greater. At the same time, the elastic telescopic giant rod 704 will pull the bottom plate 705 upward to prevent the force of the telescopic rotating rod 703 from being insufficient to lift the upper baffle 506.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
