An emergency drainage device for an open service area

Abstract

The invention discloses an emergency drainage device for an open service area and mainly relates to the field of drainage facilities for highway service areas. The device comprises a vehicle frame, wherein a rotating shaft is arranged at the bottom of the vehicle frame; a hanging rope is arranged on the rotating shaft; a gravitational block is arranged at one end of the hanging rope; a supporting frame is arranged above the vehicle frame; a buoyancy mechanism is arranged at the bottom of the supporting frame; a rain-proof bin is arranged at the top of the supporting frame; a water pumping device is arranged in the rain-proof bin; a water inlet pipe and a water outlet pipe are arranged on the water pumping device; a first driving motor and a hollow rotating shaft are arranged at the top of the supporting frame; one end of the hollow rotating shaft is closed, and the other end of the hollow rotating shaft is connected with the water outlet pipe through a universal joint; a water drainage pipe is arranged on the hollow rotating shaft, one end of the water drainage pipe communicates with the hollow rotating shaft, and a pipe layout mechanism is arranged at the other end of the water drainage pipe. The device has the benefits as follows: the device can be firmly fixed on the ground, can be used normally in extreme weather, can replace manual pipe layout and can guarantee personal safety of workers.

Description

technical field [0001] The invention relates to the field of drainage facilities in expressway service areas, in particular to an emergency drainage device for open service areas. Background technique [0002] The expressway service area is an important part of the expressway. It can provide rest places for drivers and vehicles, relieve fatigue, reduce the accident rate, and thus achieve the purpose of driving safety. The open highway service area is a new service area model developed gradually in recent years. It is established to maximize the use of land resources and realize sharing. The open expressway service area is not a fully enclosed service area in the traditional sense. It can not only provide a rest place for passing drivers and vehicles, but also farmers and small vehicles around it can go to the service area to sell local specialty products such as agricultural products, which can promote local economic development. [0003] However, due to its relatively low...

Problems solved by technology

[0003] However, due to its relatively low-lying location, water accumulation often occurs in the service area during extreme rainstorms, making it impossible for vehicles to enter, especially at the connecting passages of the parallel service area, which affects the flow of goods and Vehicle and Pedestrian Safety

[0004] At present, in order to solve the problem of water accumulation in the service area, emergency drainage vehicles are often used to pump the water in the service area to the drainage canal near the service area, and the staff are required to lay the drainage pipes to the drainage canal. In weather, the water level rises rapidly, and it is very easy to cause danger when laying pipes manually. Moreover, the height and weight of the existing emergency drainage vehicle are limited. When the water level rises too fast, the emergency drainage vehicle may be overturned and affect the use.
