High-reliability emergency drainage vehicle

Abstract

The invention belongs to the technical field of rescue vehicles and specifically relates to a high-reliability emergency drainage vehicle. The high-reliability emergency drainage vehicle comprises a vehicle cabin, the vehicle cabin is internally provided with a chassis, the chassis is provided with a water pump, a Venturi injector, an inflator and a vacuum pump, a water storage pot is arranged in the vehicle cabin, the bottom of the water storage pot is provided with a water pumping port and a water inlet, the water pumping port communicates with an inlet of the water pump through a first flexible pipe, and an outlet of the water pump communicates with the outside of the vehicle cabin through a drain pipeline; the drain pipeline communicates with an inlet of the vacuum pump through a first branch; and the top portion of the water storage pot communicates with a mixing chamber of the Venturi injector through a second flexible pipe, a high-pressure gas inlet of the Venturi injector communicates with the inflator, and the Venturi injector communicates with the outside of the vehicle cabin through an injection pipeline. The high-reliability emergency drainage vehicle has the following advantages: each apparatus is integrated on the chassis, the water pump does not have to be moved, and maintenance and repair are convenient; and water currents in the water pump are stable, the operation of a pump body is quiet and stable in an application process, there is neither noise no vibration, the service life of the water pump is long, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of rescue vehicles, and in particular relates to a highly reliable emergency drainage vehicle. Background technique [0002] With the acceleration of urban construction in recent years, insufficient construction of municipal drainage pipe networks or poor drainage of individual pipes have resulted in large areas of water accumulation in low-lying areas of cities from time to time. As we all know, the scale of the city has grown rapidly in recent years, but the corresponding public facilities have not kept up. The roads are covered by cement and asphalt in a large area. The various projects constructed have changed the topography, the city has become hardened, and the drainage pipe network has aged, which has greatly reduced the urban drainage function, and the few drainage outlets and pipelines left Frequent blockages, especially under low-lying railway culverts and overpasses.

Problems solved by technology

The roads are covered by cement and asphalt in a large area. The various projects constructed have changed the topography, the city has become hardened, and the drainage pipe network has aged, which has greatly reduced the urban drainage function, and the few drainage outlets and pipelines left Frequent blockages, especially under low-lying railway culverts and overpasses. When there is not much rain and no large-scale water accumulation occurs, water accumulation will occur due to the low-lying terrain. However, the drainage pipes in such places are also the most fragile, which leads to traffic jam, paralysis

At this time, a kind of drainage equipment that is convenient, quick, time-saving and labor-saving is needed to solve the problem. The usual method is to drag a small mobile diesel sewage pump, and then manually connect the inlet and outlet pipes to lay the water pipes out. Due to the drop of the water level, the water pump must be moved frequently. When using it, due to the large number of parts in each part, the maintenance / maintenance is very complicated.

Because the accumulated water is often caused by frequent rainfall, some garbage is mixed in the accumulated water area, and there is a vortex on the inspection well cover, so the accumulated water is easy to dissolve more air, and the pump body is prone to noise and vibration during pumping. , the pump body is easy to be damaged after long-term use
