[0002] The mobile barrier in the vehicle collision test is a high-strength device that simulates a real traffic accident and is used to evaluate the safety performance of the vehicle during a collision. It is made of high-strength materials and its structural design simulates an actual vehicle. It can simulate different types of collisions. In vehicle collision tests, the currently used mobile barrier will cause the vehicle's glass to break after colliding with the vehicle. These collapsed broken glass will splash onto the tires of the mobile barrier after the collision, causing damage to them. This damage will accelerate tire wear and thus reduce the service life of the tires. In addition, during the subsequent movement of the mobile barrier, the tires may continue to come into contact with residual glass fragments, causing continued damage. This continued damage will not only further shorten the service life of the tires, but may also affect the stability and safety of the mobile barrier. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the present invention provides a mobile barrier, which solves the problem that when the mobile barrier collides with a vehicle, the glass of the vehicle will break. These broken glass will splash onto the tires of the mobile barrier after the collision, causing damage thereto. In addition, during the subsequent movement of the mobile barrier, the tires may continue to come into contact with the remaining glass fragments, causing continued damage.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a mobile barrier, comprising a frame, an impact head connected to one side of the frame, four tires connected to the outside of the frame, four protective devices connected to the outside of the frame, four cleaning devices connected to the outside of the frame, the protective devices comprising protective plates connected to the outside of the frame, and fixing plates connected to both sides of the protective plates;

[0005] A limiting rod is slidably connected in the fixing plate, an extension rod is connected under the fixing plate, a return spring is provided on the outer sleeve of the extension rod, a scraper is connected under the limiting rod, and a collection box is connected to the front and back of the scraper.

[0006] As a further solution of the present invention: the fixing plate is connected outside the frame, and the extension rod is connected to the scraper.

[0007] As a further solution of the present invention: one end of the return spring is connected under the fixed plate, and the other end of the return spring is connected to the scraper.

[0012] 1. The mobile barrier is equipped with a protective plate, a fixed plate, a limit rod, an extension rod, a pull-back spring, a scraper and a collection box. When broken glass is flying, the protective plate protects the tire. Then, when the tire continues to move and encounters an uneven road, the pull-back spring applies elastic force to the scraper, which drives the scraper to move freely, so that the scraper always keeps in contact with the road surface. At this time, when the tire is moving, the scraper can scoop up the broken glass on the road, and the tire will not be scratched by the broken glass. In this way, the protective plate can protect the tire when broken glass is flying, and the scraper can clean the road surface when moving, ensuring the integrity of the tire.

[0013] 2. The mobile barrier is equipped with a connecting plate, a motor, an elastic telescopic rod and a brush head. When the tire moves, the motor is started. Then, when the scraper scoops up broken glass, the motor drives the elastic telescopic rod to rotate, and the elastic telescopic rod drives the brush head to rotate. The brush head rotates and cleans the broken glass on the scraper into the collection box, so that the scraper will not be blocked and the cleaning work can be carried out continuously.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a mobile barrier, including a frame 1, an impact head 2 is connected to one side of the frame 1, four tires 3 are connected to the outside of the frame 1, four protective devices 4 are connected to the outside of the frame 1, and four cleaning devices 5 are connected to the outside of the frame 1. The cleaning device 5 includes a connecting plate 51, the connecting plate 51 is connected to the outside of the frame 1, a motor 52 is connected under the connecting plate 51, an elastic telescopic rod 53 is connected under the motor 52, and a brush head 54 is connected under the elastic telescopic rod 53. By setting the elastic telescopic rod 53 and the brush head 54, the elastic telescopic rod 53 cooperates with the brush head 54, so that the elastic telescopic rod 53 exerts elastic force on the brush head 54, so that the brush head 54 always maintains contact with the scraper 46;

[0021] The brush head 54 is overlapped on the scraper 46. The protective device 4 includes a protective plate 41. By setting the protective plate 41 and the tire 3, the protective plate 41 cooperates with the tire 3 to achieve the protection of the protective plate 41 on the tire 3, thereby preventing the tire 3 from being impacted by broken glass.

[0022] The protective plate 41 is connected to the outside of the frame 1. Both sides of the protective plate 41 are connected to the fixing plate 42. The fixing plate 42 is connected to the outside of the frame 1. The extension rod 44 is connected to the scraper 46.

[0023] A limit rod 43 is slidably connected to the fixed plate 42, and an extension rod 44 is connected to the lower portion of the fixed plate 42. A return spring 45 is provided on the outer sleeve of the extension rod 44. By providing the return spring 45, during operation, the return spring 45 applies elastic force to the scraper 46, so that the scraper 46 always keeps in contact with the ground.

[0024] One end of the return spring 45 is connected to the bottom of the fixed plate 42, and the other end of the return spring 45 is connected to the scraper 46. The scraper 46 is connected to one side of the protective plate 41. The collection box 47 is connected to one side of the protective plate 41. The scraper 46 is connected under the limit rod 43. The front and back sides of the scraper 46 are connected to the collection box 47. By setting the collection box 47 and the brush head 54, the collection box 47 cooperates with the brush head 54, so that the brush head 54 can clean the broken glass into the collection box 47 for collection.

[0025] The working principle of this utility model is:

[0026] When broken glass is flying, the protective plate 41 protects the tire 3. Then, when the tire 3 continues to move, when encountering an uneven road, the return spring 45 applies elastic force to the scraper 46, and the elastic force drives the scraper 46 to move freely, so that the scraper 46 always keeps in contact with the road surface. At this time, when the tire 3 is moving, the scraper 46 can shovel up the broken glass on the road. When the tire 3 moves, the motor 52 is started. Then, when the scraper 46 shovels up the broken glass, the motor 52 drives the elastic telescopic rod 53 to rotate, and the elastic telescopic rod 53 drives the brush head 54 to rotate. The brush head 54 rotates and cleans the broken glass on the scraper 46 into the collection box 47, thereby completing the protection of the tire 3.
