Description

Anti-blocking flood prevention and drainage mobile pump truck Technical Field The invention relates to the technical field of drainage pump valves, in particular to an anti-blocking flood prevention and drainage mobile pump truck. Background In the first line of urban water logging rescue, construction site emergency drainage or emergency flood prevention, you can often see a device like a mobile water faucet, which is a mobile pump truck for flood prevention and drainage. In short, the system is a mobile fire fighting team with a heart (power system) and a blood vessel (pump body pipeline), and is specially responsible for sucking accumulated water at a low position up and then spitting the accumulated water into a remote river or a drainage pipe network in the shortest time. The core technology of the pump truck is that a character-suction to direct spitting. The system is mainly applied to emergency flood prevention under dangerous working conditions, and is not required to be filtered through a grating and then treated as in a sewage treatment plant, and the core task of the system is that accumulated water (whether clean rainwater or sewage mixed with silt and plant fragments) is conveyed from point A to point B (such as a river channel, a sewer or a low-lying place) in the shortest time, sediment, garbage and even some less serious pollutants are mixed in water, and the like, and the accumulated water is usually discharged along with the water directly on the premise of continuously draining waterlogging without blocking a pump body, so that interception or separation treatment (heavy polluted sewage or transportation to the sewage treatment plant by adopting a tank truck) is not carried out. They can work through the trailer removal to waterlogging department directly, and the inlet tube stretches into sewage just can take away sediment, rubbish one strand brain in the water entirely, because saved complicated filtration link, and deployment working speed is extremely fast, just can take out to start, and the drainage just can be opened to next danger area, especially adapted emergency rescue. Structurally, it is generally composed of a diesel engine (providing powerful power without external power supply), a sewage pump (core working part) and a mobile chassis (trailer or vehicle-mounted, ensuring rapid arrival). In order to cope with complex sewage environments. Meanwhile, in order to ensure long-time stable operation, the modern pump truck also integrates an intelligent control system, a hydraulic support leg (used for stabilizing a car body) and even a lighting system, so that all-weather combat can be ensured at night or under severe road conditions. However, the conventional pump truck in the prior art mainly has the following two defects: ① The prior art anti-blocking mainly relies on impeller design, wherein the characteristic of 'no blocking' of the impeller (such as a rotational flow type or an open type impeller) is emphasized more, the impeller tries to contain impurities by enlarging a flow passage, so that the impurities cannot be blocked into a blade gap, and the impurities are far away from the blades by centrifugal force, so that the impurities directly go out from a water outlet pipe of the side wall along the inner wall of the pump for one circle, and are prevented from contacting with the blades or striking the blades. However, when encountering large-particle solids (such as stones, concrete fragments, plastic bottles and the like), mechanical jamming still possibly occurs, and once the jamming occurs, overload burning of a motor or instant damage of mechanical sealing is often further caused, so that equipment is directly scrapped on site, and an emergency drainage task cannot be completed; ② The design of the filtering device before the pump is unreasonable, and secondary blockage is easy to be caused, wherein part of equipment is provided with a filter screen, a grating and the like in a pipeline before the pump for avoiding large particles from entering the pump body, but the structure of the filtering device is mainly a simple fixed grating, only fixed interception can be performed, and impurities under interception need to be stopped for cleaning. In the actual pumping process, fibrous matters (such as pasture and water and plastic bags) and viscous impurities in the sewage are extremely easy to quickly paste on the surface of the filter screen, so that the water inlet channel is completely blocked. The design has no protection effect, forces operators to stop and clean frequently, greatly reduces the drainage efficiency, and breaks through the original purpose of continuous operation of emergency equipment. In summary, the prior art lacks a cooperative mechanism for preventing blocking, flood control and drainage of mobile pump truck, which can effectively intercept lethal large particles (prevent the pump body from being blocked inside) and automatically remove intercepti
