Abstract

The invention discloses an ejector device which is mainly characterized in that an ejector is connected with a pump connected with a power machine and then is connected with an ejecting gun by an ejecting pipe connected therewith, the ejector and the pump are placed in a storage water tank on a fire control car, the ejecting gun is above the fire control car and presents an angle of elevation of 40-80 degrees. The ejector device applies work relying on the power machine, water enters the ejector by the pump and accumulates certain energy in the ejector and then is ejected by the ejecting pipe and the ejecting gun, water ejecting height can reach 300m, when water ejecting height reaches 43.5m, water ejecting distance is about 120m and the diameter of landing area is 3-5m. Therefore, the ejector device is applicable to the fire control car for extinguishing fire with height within 300m as well as to a forest fire control car, and can extinguish a fire source in the central area of a forest.

Description

technical field [0001] The invention relates to a spraying device, which can be installed on a fire truck and used for fire extinguishing, lifesaving and emergency rescue. Background technique [0002] Usually, the spraying device installed on the fire truck mainly includes a motor and a fire pump connected to it in turn, a spraying pipe and a spraying water gun. The injection device sprays water through the pressure of the fire pump, and its injection height is about 40-50m, and the injection pipe used is relatively long. Although it can effectively extinguish the fire within the height of 40-50m, it is powerless to extinguish the fire of high-rise buildings above 50m or the fire source area in the forest central area. Like this, can bring very big difficulty to rescuing state property and injured person, even can cause the heavy loss of state property and undue casualty accident. Contents of the invention [0003] The object of the present invention is to provide a kin...
