Problems solved by technology
[0004] At present, the speed bumps laid on the road are all in a fixed state. The original design of the speed bumps is to reduce the speed of the vehicle. When the speed of the vehicle is already very slow, the speed bumps at this time lose their original meaning and reduce the The belt will also produce bumps, and it is easy to scratch the vehicle with a lower chassis; there are many disadvantages

Embodiment Construction
[0029] The self-lifting deceleration belt used in the present invention adopts hydraulic control to lift the deceleration belt. When the vehicle passes at a high speed per hour, the contact time between the vehicle and the pressure plate is short and the kinetic energy of the vehicle itself is relatively large. The pressure exerted by the pressure-bearing plate is relatively large and the speed of the pressure-bearing plate descends quickly; when the vehicle passes at a low speed or slowly, the contact time between the vehicle and the pressure-bearing plate is long and the kinetic energy of the vehicle itself is relatively small. The pressure exerted by the pressure plate is relatively small and the pressure plate obtains a relatively small descending speed; the displacement generated by the different speeds of the pressure plate is used to sense the difference, and the movement area of the pressure plate in the vertical direction is controlled. Based on this The principle is...

The invention discloses a water-pressure control based automatic-lifting speed bump for intelligent transportation. The water-pressure control based automatic-lifting speed bump comprises a base plateprovided with an internal base groove with upwards opening. A bearing plate is in sliding fit in the base plate, touches the wall of the base groove, and can move vertically. A closed water storage box and a plurality of lifting units are mounted between the base plate and the bottom surface of the bearing plate; the water storage box is communicated with a running water pipe, and is connected with one lifting unit through an inlet passage and a drain passage. The upper end face of the base plate is provided with a transitional edge extending outwards and inclining; the end, facing the bearing plate, of the transitional edge is higher, while the lower end of the transitional edge is flush with the road surface. The inlet passage and the drain passage are respectively communicated with theinner cavity of a cylinder body of the corresponding lifting unit; a check valve a for controlling water in the water storage box to flow into the cylinder body is arranged on the inlet passage, anda check valve b for controlling water in the cylinder body to flow to the water storage box is arranged on the drain passage.
Description
[0001] The present invention is a divisional application of the invention patent with the application date of March 1, 2017, the application number: 2017101156877, and the invention title of "water pressure control type vertical pressure self-elevating speed bump". technical field [0002] The invention relates to a road deceleration belt, in particular to a lifting type deceleration belt. Background technique [0003] The deceleration belt is the road belt that reduces the speed of the vehicle. It is placed on the required road section to reduce the speed of passing vehicles. It can cause large bumps to the vehicles passing at high speed and cause certain damage to the shock absorption of the vehicle. The resistance generated by it can be reduced. Speed: With the development of the economy, the number of vehicles is rising in a straight line. In order to restrain the speed of vehicles and protect the safety of pedestrians, the number of speed bumps laid on the road is also i...
