System and method for measuring wind resistance parameter of water mist

Abstract

The invention relates to the technical field of fire protection and discloses a system and method for measuring a wind resistance parameter of water mist. The system comprises a nozzle connected with a water pipe, wherein the other end of the water pipe is connected with a water tank through a water pressure source; at least two first testers with the same model are deployed on a jet path of the nozzle to measure droplet diameters and droplet velocity of the water mist on different sections; the first testers are connected with a data processing terminal; the data processing terminal is also connected to a second tester for testing water pressure of output water; and an air supply device is also deployed on the jet path of the nozzle. The corresponding measurement method comprises the following steps executed by the data processing terminals: measuring the water pressure of the water pipe through the second testers, and obtaining the droplet diameters and the droplet velocity of the water mist of at least two sections through at least two first testers with the same model deployed on the jet path; and carrying out corresponding data processing according to the water pressure water and the droplet diameters and the droplet velocity of the water mist of different sections.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a system and method for measuring wind resistance performance parameters of fine water mist. Background technique [0002] Forest is one of the most important and indispensable resources for human survival and social development, and it is also the protector of the earth's ecological balance. However, due to the uncontrolled activities of human beings and the impact of natural factors, forest fires occur frequently, and each large forest fire brings huge economic losses and casualties. The indirect impact of fire on global climate, vegetation and ecological environment far exceeds other direct economic loss. [0003] The development of modern society and the advancement of science and technology have put forward higher requirements for the rapidity, effectiveness and environmental protection of fire suppression methods. Traditional physical methods of fire suppression, ...

Problems solved by technology

However, the fine water mist is light in weight and is greatly affected by the wind. At the same time, it is affected by many factors such as gravity, wind lateral force, and pressure energy converted into motion potential energy. At present, there are no wind resistance performance parameters of fine water mist that can guide the design of fire extinguishing nozzles. Measurement methods and systems
