Device for preventing vehicle from being flooded

Abstract

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.

Description

technical field [0001] The invention relates to a device for preventing vehicles from being flooded, which belongs to accessories of transportation machinery. Background technique [0002] Whenever I watch the news footage of a certain place being flooded, there are also pictures of vehicles being flooded, especially this year. When the heavy rain comes, most people are prepared, such as parking the car in the community, in the parking lot, or in a high place. People are just worried about the possibility of excessive rainwater, but they cannot raise the vehicle and seem helpless. Even, in the dormitory of the community, he saw his car parked downstairs flooded. Although there are technologies to prevent flooding, such as adding buoyancy airbags under the vehicle to drag the vehicle up, it is difficult to solve the problems of airbag puncture and drift. 201521119583.6 includes slide rails and winches, and the lifting structure is complex and difficult to implement.

Although there are technologies to prevent flooding, such as adding buoyancy airbags under the vehicle to drag the vehicle up, it is not easy to solve the problems of airbag puncture and drift

201521119583.6 includes slide rails and winches, the lifting structure is complex and difficult to implement

The power is operated by a manual oil pump, which is inconvenient. In addition, the stored hydraulic oil pump and oil tank are on the car all year round, which increases the weight of the car and increases the risk of fire.
