Description

TECHNICAL FIELD

[0001] The present application relates to the field of emergency drainage equipment, in particular to a double-pump closed drainage robot. BACKGROUND

[0002] The drainage robot is a new type of equipment for dealing with urban waterlogging, and its role in drainage rescue and emergency rescue is becoming more and more important. The existing drainage robots mainly have two types, one is a self-walking drainage robot with a power system, this type of equipment has an engine or a power storage device, which causes the robot to be unable to completely enter the water, otherwise the power system will fail; the other type is without a power system, the robot takes power or hydraulic power from other equipment, but the electrical equipment of its control system also cannot be immersed in water.

[0003] From the above existing technology, although the power type and control method of the drainage robot are different, the electrical equipment has special requirements for immersion in water, so it is limited by the water depth. During the drainage operation, it is an "edge type" drainage, that is, the drainage robot cannot completely enter the water accumulation area, and only stops at the edge of the water accumulation point during drainage. The robot will carry the water pump head into the water through certain measures, which will cause the water level to drop, and the drainage robot must be stopped and moved to the deep water area to meet the water level requirement of the water pump. This not only makes the operation process extremely complex, but also easily causes the water pump to be damaged due to the water level not being lowered in time to move the equipment.

[0004] The utility model patent with patent number CN207565421U: a submersible tracked drainage vehicle, including a drainage vehicle body and a remote control device; the drainage vehicle body includes a tracked walking chassis, a submersible pump and a waterproof control cabinet arranged on the chassis, the waterproof control cabinet seals the electrical devices by pouring sealing glue, the sealing method is "one-time" sealing, which can achieve certain effect, but the method has high cost, and the electrical system cannot be repaired in the later period, and must be replaced as a whole, so it has little practical significance.

[0005] In addition, as an emergency rescue, the operation is urgent, and the drainage robot needs to work continuously for a long time, but due to the need to stop the power system for cooling, the actual drainage is intermittent.
