A device for preventing a vehicle from being flooded is characterized in that multi-stage plunger sleeve cylinders with downward extension directions are fixed at four positions on front, rear, left and right crossbeams of a vehicle chassis, and the multi-stage plunger sleeve cylinders firstly recommend that a working medium is air, secondly water and thirdly hydraulic oil. Two sections of <-shaped grooves are exposed on the circumference of the plunger at the junction of the stages, and a limiting clip with a <-shaped bulge on the inner edge is used for manually limiting the plunger between the stages. The air pump or the hydraulic pump controls the four multi-stage plunger sleeve cylinders to ascend and descend through the air delivery pipes or the hydraulic pipes and the three-way valves. The descending of the four multi-stage plunger sleeve cylinders is achieved through outlet throttle valves of the multi-stage plunger sleeve cylinders. The device is simple, convenient to operate,feasible in technology and reliable in work.

    一种防止车辆被淹装置,在车辆底盘的前后左右大梁上的四个位置,固定有伸长方向向下的多级柱塞套筒缸,所述多级柱塞套筒缸首先推荐的工质是空气、其次为水,再次为液压油。在级与级交界的柱塞圆周上露出有两段“∠”形状凹槽,有内边缘有“∠”形状凸起的限位卡子通过手动将级与级间的柱塞限位。气泵或者液压泵通过输气管或者液压管和三通阀控制四个多级柱塞套筒缸的升高,降落通过多级柱塞套筒缸的出口节流阀来实现的。本发明设备简单、操作方便、技术可行、工作可靠。
