  • BACKGROUND OF THE INVENTION For mountainous landforms, the terrain of the forest is complex, the terrain is steep, the grass is full of vegetation, and the vegetation is rich. Once a forest fire occurs, the fire intensity is high and the fire speed is fast. The wind extinguisher, the second tool, the fire bomb and the piggyback type are used.

  • the above conventional fire tools are powerless, and they can only hope to sigh.
  • Water is the most common, cheapest and most effective natural fire extinguishing agent. Water fire extinguishing is the preferred method of forest fire protection in many forestry developed countries. Some existing economically sound places have taken the lead in applying water pumps, water trucks, and piggybackers. However, the water source for water fire suppression is restricted by the steep slope of the fire field and the long distance. Knapsacks 34 Fire-fighting is subject to heavy loads and no subsequent water supply on the fire. It is generally used only for cleaning fires and cannot be used to effectively control fire lines, especially high-intensity fire lines. Waterwheels are costly and limited by terrain, and are not applicable where some vehicles cannot.
  • the existing fire pump usually uses a motor to drive the pulley to work, and the lift is small.
  • a water pump is usually placed at a certain height, and the water is pumped to the required height step by step through a multi-stage pump.
  • the application mode of "multi-stage docking and infinite water delivery" for water pump fire extinguishing due to the unbalanced pumping pressure between the pump and the pump, the phenomenon that the water belt 33 is taken out and crashes often occurs, and it is generally impossible to transfer water to the fire line.
  • Forest fires occur in forested mountains, steep mountains and steep slopes, impassable roads, and difficult water sources. Forest fires do not require large flows of water to extinguish fires, but require long-range high-lift water delivery. Therefore, forest fire pumps should use lower flow, higher lift, lighter weight, and smaller volume equipment to facilitate carrying and working in the mountains, but not directly apply to large flow, low lift, size and weight are not easy to go uphill. City fire pump preparation. The existing fire-fighting water pump is not enough to understand the fire-fighting of forests. If there is no water in the forest, it will require a large flow, high water pressure and long-range misunderstanding. Second, the application of water fire to forests The study of ideas and models is not enough.

  • the existing submersible pump because it only uses the centrifugal force of the multi-stage impeller to pressurize, the pressurization is limited, and the lift can not meet the needs of fire fighting, so it is generally used in deep well operations and has not been used as a fire pump.
  • the existing method of moving the water pump only the impeller rotates without the propeller, so the existing movement method of the submersible pump cannot form a spiral isolation propulsion mode to further increase the water pressure, so the head and the transmission The water distance is still difficult to meet the needs of fire protection, so the existing submersible pumps have not been applied to fire protection, especially forest fire protection.
  • the fire truck equipped with the existing water pump has a small lift and high cost, and often has the phenomenon of taking the water out of the water and crashing.

Abstract

L'invention concerne une pompe à incendie et son fonctionnement, un système de lutte contre les incendies et une autopompe. La pompe comprend un corps, un moteur monté dans le corps, et au moins deux étage d'ensembles roues montés en série. Un orifice d'admission d'eau est formé sur le corps, entre le moteur et les ensembles roues. Les ensembles roues sont montés coaxialement et en série sur l'arbre d'entraînement. L'arbre d'entraînement est fixé sur l'arbre moteur ou est coaxial avec ce dernier. L'ensemble roue comprend un diffuseur, une roue, un élément de fermeture d'extrémité et une bague de retenue placée sur le pourtour du diffuseur et de la roue, ces quatre éléments étant installés les uns à la suite des autres. Le diffuseur comporte une pluralité de premières aubes, et la roue comporte une pluralité de secondes aubes correspondantes en nombre et en position. Le diffuseur est fixé sur l'arbre d'entraînement, la roue est couplée de manière pivotante avec l'arbre d'entraînement, et l'élément de fermeture d'extrémité est traversé par l'arbre d'entraînement. Lors du fonctionnement de la pompe, l'arbre d'entraînement tourne conjointement à l'arbre moteur et entraîne le diffuseur monté sur l'arbre d'entraînement, la roue, l'élément de fermeture d'extrémité et la bague de retenue présentant un mouvement irrégulier. On obtient ainsi une hauteur de refoulement et une distance d'admission d'eau accrues.
