Mixed feed system of variable-flow foam and fire fighting truck

Abstract

The invention belongs to the field of fire fighting and extinguishment, and specifically relates to a mixed feed system of variable-flow foam and a fire fighting truck. The mixed feed system comprisesa frame body, an isolating board, a mixing and stirring mechanism, a centrifugal mechanism, a power transmission mechanism and a flow regulation mechanism, wherein a liquid inlet pipe is fixedly installed in the right end wall of the frame body, and the mixing and stirring mechanism is arranged in the right end of the frame body; a mixing rod is rotatably installed in the frame body in a penetrating mode, the left side of the mixing rod is rotatably connected to the middle of the isolating board in the penetrating mode, and the right end of the mixing rod is rotatably connected to a motor; the power transmission mechanism is arranged on the left side of the isolating board; the centrifugal mechanism is arranged on the left side of the power transmission mechanism; a conveying groove is formed in the left end of the mixing rod; and the flow regulation mechanism is fixedly connected to the lower end of a liquid outlet pipe by virtue of a flange plate. The mixed feed system is mainly used for solving the problems of waste and environmental pollution caused by incapability of controlling the amount of discharged foam and incapability of controlling the discharge distance of an existing foam extinguishing system.

Description

technical field [0001] The invention belongs to the field of fire extinguishing, in particular to a variable flow foam mixing supply system and a fire truck. Background technique [0002] The principle of foam fire extinguishing is that when extinguishing a fire, a large amount of carbon dioxide and foam can be ejected, and they can adhere to combustibles, so that the combustibles are isolated from the air, so as to achieve the purpose of extinguishing the fire. [0003] Fire trucks, also known as fire trucks, refer to special vehicles that are mainly used to perform fire response tasks. Fire departments in most countries, including China, also use them for other emergency rescue purposes. Fire trucks can transport firefighters to the scene of disasters and provide them with a variety of tools to perform disaster relief tasks. Modern fire trucks are usually equipped with large fire extinguishing equipment such as water tanks, water pumps, and foam fire extinguishing devices....
