Description

Technical Field

[0001] The invention relates to an amphibious drainage device, belonging to the fields of mechanical technology and emergency rescue and flood drainage. Background Art

[0002] At present, the earth's climate is abnormal, and drought and flood disasters are frequent. Especially in recent years, many cities in my country have suffered from waterlogging caused by heavy rains and floods, resulting in road traffic paralysis, power and water supply interruptions, water intrusion into low-lying buildings, underground buildings and civil air defense projects, and the water is often unable to be drained in time, causing a large amount of property and equipment to be damaged. The economic losses incurred are difficult to estimate.

[0003] In the existing technology, amphibious drainage devices all adopt the solution of integrating the power system for driving the tracked drainage vehicle on the body of the tracked drainage vehicle, but this solution will cause the tracked drainage vehicle to be either large in size and unsuitable for drainage operations in a narrow space; or the tracked drainage vehicle can be reduced in size by installing a small power system, but the reduced power leads to low drainage efficiency and fails to achieve the purpose of rapid drainage. In addition, the existing tracked drainage vehicle can perform drainage operations at the water's edge, and when the water level drops, it will drive closer to the deep water. At this time, since the connected drainage pipe is filled with water with a relatively large mass, the tracked vehicle cannot be dragged, and the water in the pipe needs to be drained before the tracked vehicle can drive and operate, which increases the complexity of the operation.
