The present invention relates to the technical field of grounding protection devices for power grids, and discloses a grounding protection device for smart grids, including a telescopic bracket, two limit assemblies and a conductive bar, wherein the telescopic bracket has two telescopic ends that can move closer to or farther from each other; two limit assemblies are respectively arranged at the two telescopic ends, and the limit assembly includes two limit brackets, which are respectively arranged on both sides of the telescopic bracket and can be rotatably connected to the telescopic bracket. When the limit bracket is rotated to be perpendicular to the telescopic bracket, a limit structure is formed between the limit bracket and the telescopic bracket; the conductive bar is detachably connected to the telescopic bracket; wherein the telescopic bracket, the limit bracket and the conductive bar are all conductive and electrically connected to each other. The telescopic bracket and the limit bracket can be unfolded and folded, and there is no need to fix each component by welding. The telescopic bracket and the limit bracket extending in different directions increase the length of the grounding, which can effectively reduce the grounding resistance.

The application relates to a road section vehicle group dissolving method based on real-time vehicle speed regulation, which comprises the following steps: S1, acquiring real-time traffic information of a road section; S2, when the headway between a host vehicle and a front vehicle in the same lane is less than a safe following headway and the headways between the host vehicle and front vehicles in adjacent lanes are both less than a safe lane-changing headway, the front vehicle in the same lane and the front vehicles in the adjacent lanes form a vehicle group; S3, judging the risks of vehicles in the vehicle group, and the vehicle with the maximum risk value R being the risk source of the vehicle group; S4, regulating the vehicle speed of the risk source vehicle of the vehicle group; and S5, when the host vehicle satisfies the condition that the headway with the front vehicle in the same lane is greater than or the headway with the front vehicle in the adjacent lane is greater than, the original vehicle group is dissolved. The application dissolves the vehicle group and reduces the driving risk of the road section by regulating the real-time vehicle speed of the risk source vehicle.

The utility model relates to the technical field of magnetic particle flaw detectors, in particular to a magnetic particle flaw detection device for bolts, including a collection table, and further comprising: a conveyor belt, which is arranged at one end of the collection table, and baffles are fixedly arranged on the left and right sides of the conveyor belt; a flaw detection component, which is fixedly arranged outside the baffle and is used for magnetizing and flaw detecting the bolts; two groups of racks, which are respectively arranged on the inner sides of both sides of the conveyor belt, and gears are arranged on the two groups of racks, and the racks are meshed with the gears; when the conveyor belt is started, it can drive the gears on the telescopic placement rack to rotate, so that the bolts on the telescopic placement rack rotate. The arc-shaped notch on the support plate that fits the size of the bolts and the rolling columns in the notch rotate simultaneously when the gears drive the bolts, making the bolts rotate more smoothly on the telescopic placement rack, enabling the bolts to receive flaw detection in all directions during the conveying process, ensuring no dead angle in detection, and improving the accuracy of detection.
