It is only for the convenience of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation. Therefore, it should not be construed as a limitation to this application.

[0028] The present utility model provides a device for preventing pollution of road markings during construction as shown in Figures 1 to 4 and includes:

[0029] A semi-circular cover plate 1 for protecting the road markings. At the same time, two sets of universal wheels are installed inside the cover plate 1, and the bottom of the universal wheels is lower than the bottom of the cover plate 1 to prevent the cover plate 1 from rubbing against the road surface.

[0030] A fixed box 2 is installed at the tail of the engineering vehicle. Two sets of movable frames 3 are provided at the bottom of the fixed box 2. The movable frames 3 are hinged to the top of the cover plate 1. A panoramic camera assembly 4 is installed on the back of the movable frames 3, and

[0031] A rotating box 5 is arranged above the movable frame 3. A rotating shaft 6 is fixed to the top of the movable frame 3. The top of the rotating shaft 6 penetrates into the inner cavity of the rotating box 5 and is rotatably connected to the rotating box 5 through a bearing.

[0032] An adjusting assembly 7 is used to adjust the positions of the two rotating boxes 5 at the bottom of the fixed box 2 to prevent the vehicle from being unable to be parallel to the markings during driving and to correct the cover plate 1.

[0033] A steering assembly 8 is arranged inside the rotating box 5 to drive the rotating shaft 6, the movable frame 3 and the cover plate 1 to adjust the angle, so as to achieve full coverage of the cover plate 1 for the markings.

[0034] Through the infrared and radar scanning integrated inside the panoramic camera assembly 4, the markings are accurately identified, the driving motor 71 is controlled, and then the connecting plate 74 is driven by the threaded rod 72 and the threaded sleeve 73 to adjust the position of the movable frame 3, so that the cover plate 1 is located above the markings. At the same time, the angle of the movable frame 3 is deflected by the rotating assembly to realize the free adjustment of the cover plate 1 in the vehicle driving direction, avoid the vehicle driving direction being not parallel to the markings, and facilitate the automatic adjustment of the cover plate 1 to cover the markings completely. The driver can not only focus more on driving the vehicle, but also the effect of preventing pollution of the markings is better.

[0035] The panoramic camera component 4 is integrated with sensors, which rely on LIDAR (laser radar) to identify the road. The autonomous driving car can identify pedestrians, accurately sense the direction of lane lines, and turn along lane changes. It involves many cutting-edge technologies such as artificial intelligence, cloud computing, big data, radar detection, positioning and navigation, and has the characteristics of highly integrated technology. Based on the autonomous driving system installed on existing vehicles, it only needs to identify the markings.

[0036] The adjusting assembly 7 includes a driving motor 71 fixed to one end of the fixed box 2, the output shaft of the driving motor 71 passes through the inner cavity of the fixed box 2 and is fixed with a threaded rod 72, the end of the threaded rod 72 is rotatably connected to the inner cavity of the fixed box 2 through a bearing, the outer side of the threaded rod 72 is threadedly connected with two groups of threaded sleeves 73, the outer side of the threaded sleeve 73 is fixed with a connecting plate 74, the connecting plate 74 passes through the fixed box 2 and is fixedly connected to the top of the rotating box 5, the driving motor 71 drives the threaded rod 72 to rotate, and then the threaded rod 72 is hidden; the threaded sleeve 73 drives the two groups of connecting plates 74 to move synchronously, so that the cover plate 1 on the lower side closer to the mark is quickly transferred to the top of the mark, shortening the adjustment time of the cover plate 1.

[0037] The steering assembly 8 includes a rotating motor 81 fixed to the inner cavity of the rotating box 5, the output shaft of the rotating motor 81 is fixed with a driving gear 82, and the surface of the rotating shaft 6 is fixed with a driven gear 83 meshing with the driving gear 82. The driving gear 82 is driven to rotate by the rotating motor 81, and the rotating shaft 6 is then driven to rotate by the driven gear 83 to deflect the movable frame 3 at an angle, so that the cover plate 1 and the forward direction of the vehicle have an angle, thereby preventing the vehicle's driving route from affecting the marking line covered by the cover plate 1.

[0038] The movable frame 3 includes a fixed frame 31 fixedly connected to the rotating shaft 6, and the bottom of the fixed frame 31 is movably connected with two sets of movable rods 32 through a movable shaft. The end of the movable rod 32 away from the fixed frame 31 is movably connected to the top of the cover plate 1 through a movable seat. The fixed frame 31 and the movable rod 32 are movably connected to form the movable frame 3. At the same time, the movable rod 32 is used to connect the cover plate 1 to the rotating box 5, and the opening of the cover plate 1 is kept always facing downward.

[0039] An electric push rod 9 is embedded in the top of the fixed frame 31, and a guide wheel 10 is installed on the top of the inner cavity of the fixed frame 31. The outer side of the guide wheel 10 is connected to the transmission with a wire rope 11. One end of the wire rope 11 is connected to the top of the cover plate 1, and the other end of the wire rope 11 is fixedly connected to the piston rod of the electric push rod 9. Through the setting of the electric push rod 9, it is convenient to pull the cover plate 1 through the wire rope 11, and the guide wheel 10 is used to realize the upward movement of the cover plate 1, so that a single group of cover plates 1 fall off the road surface, avoiding the influence of a group of cover plates 1 that do not cover the marking line on the engineering task.

[0040] A control cabinet 12 is installed on the top of the fixed box 2. A control circuit board is integrated inside the control cabinet 12, and the control circuit board is electrically connected to the panoramic camera assembly 4, the driving motor 71, the rotating motor 81, and the electric push rod 9 respectively. Through the circuit board integrated inside the control cabinet 12, it is convenient to quickly process and analyze the information collected by the panoramic camera assembly 4, and at the same time control the driving motor 71, the rotating motor 81, and the electric push rod 9 to cooperate with each other to achieve accurate covering of the marking line by the cover plate 1.

[0041] Two sets of mounting brackets 13 are fixed on both sides of the top of the fixed box 2. Mounting long grooves are formed inside the mounting brackets 13. The device can be installed at the rear end of the engineering vehicle through the two sets of mounting brackets 13. At the same time, the mounting long grooves are suitable for the installation of most vehicles, which is convenient for adjusting the distance between the cover plate 1 and the road surface.

[0042] During specific use, the fixed box 2 is installed at the rear of the engineering vehicle by using the mounting brackets 13, and the panoramic camera assembly 4 is in the same direction as the vehicle driving direction. When the vehicle driving direction and the marking line are roughly in the same direction, the panoramic camera assembly 4 takes pictures and identifies the surrounding environment in the vehicle driving direction, identifies the position of the marking line, and then controls the driving motor 71 through the control cabinet 12. The driving motor 71 drives the threaded rod 72 to rotate, and then the threaded rod 72 drives the connecting plate 74 to move left and right through the threaded sleeve 73, so that the cover plate 1 and the movable frame 3 on the closer side quickly move above the marking line. When there is an angle between the vehicle driving direction and the extension direction of the marking line, the control cabinet 12 starts the rotating motor 81. The rotating motor 81 drives the driving gear 82 to rotate, and the driving gear 82 drives the driven gear 83 to rotate the rotating shaft 6, so that the movable frame 3 deflects to adjust the movable frame 3 and the cover plate 1 to be in the same direction as the extension direction of the marking line. At the same time, the cover plate 1 that is not covering the marking line moves up under the traction of the electric push rod 9 and the steel wire rope 11 and detaches from the road surface. The driver only needs to ensure that the vehicle is roughly in the same direction as the extension direction of the marking line, and the device can automatically identify and calibrate.

[0043] The above is only a preferred embodiment of the present invention, and it is not used to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
