The invention discloses an intelligent separation guardrail capable of automatically preventing pedestrian from climbing. The intelligent separation guardrail comprises a base. A wobbling device is arranged in the upper end face of the base. The wobbling device comprises rocker rod cavities which are symmetrically formed in the upper end face of the base in the front-back direction and are provided with upward openings. Rocker rods are arranged in the rocker rod cavities, and limiting grooves are formed in the rocker rods in a penetrating manner in the front-back direction. Limiting rods are arranged in the limiting grooves in a sliding manner, and a transmission device is arranged at the lower portion of the interior of the base. An inflation device is arranged at the upper end of the base. By means of the intelligent separation guardrail, people streams or vehicle streams can be effectively separated, when pedestrians try to climb and cross the guardrail, the guardrail is automatically started so that the pedestrians cannot climb under the assistance of force due to a soft running manner, the phenomenon that the pedestrians cross the guardrail to cause traffic jam or even trafficsafety accidents is prevented, safety of a traffic road is improved, meanwhile, the guardrail is automatically stopped when no pedestrian crosses the guardrail, and the guardrail is economical and environment-friendly.

The invention discloses an automobile accelerator anti-misstepping device, which is arranged under the accelerator pedal and includes a hydraulic device, hydraulic oil arranged in the hydraulic device, an isolation plate extending from the inner side to the outer side of the hydraulic device, and a device. The large oil inlet hole and the small oil inlet and outlet hole at the lower end of the isolation plate, the liftable stopper on the right side of the isolation plate; the upper end surface of the isolation plate and the top of the hydraulic device The lower end surface of the isolation plate is connected with the bottom surface of the hydraulic device. The isolation plate divides the hydraulic device into a left oil tank and a right oil cylinder. A refueling and venting hole is provided on the upper end of the left oil tank. The bottom of the right oil cylinder is provided with an elastic member capable of exerting longitudinal elastic force, and a pressing member that can exert pressure downward is pierced on the upper end surface of the right oil cylinder, and the pressure applying member and the elastic member The upper end surface is in contact, and the upper end surface of the pressing member is in contact with the lower surface of the accelerator pedal.

The invention discloses a self-adaptive multidirectional dislocation method and a self-adaptive multidirectional dislocation device for a retractable device. According to the technical scheme, comb plate dislocation and elastic damping dislocation are combined; an elastic damping dislocation device is arranged at the root of a movable steel comb plate of a comb plate dislocation device, comprises at least one spring component or elastic component made of polyurethane polymer composites, and is in point contact with the movable steel comb plate. By the self-adaptive multidirectional dislocation method and the self-adaptive multidirectional dislocation device, the problems that steel comb-tooth-shaped retractable devices are poor in adaptability to dislocation, tires are punctured by bolts, driving safety is affected, service life is not ideal and the like in the prior art are solved; the self-adaptive multidirectional dislocation device is simple in structure and low in production cost.
