Fire-fighting equipment demonstration device applied to teaching

Abstract

The invention discloses a fire-fighting equipment demonstration device applied to teaching. The demonstration device comprises supporting legs, an operation panel and a liquid crystal display, a plurality of simulation grooves are formed in the upper surface of the operation panel, a plurality of extinguisher placing grooves are formed in two sides of each simulation groove, different kinds of extinguishers are placed in the extinguisher placing grooves, each extinguisher is provided with a display screen, a label area and an inflation inlet, a pressure sensor is arranged in each extinguisher,the liquid crystal display is fixedly arranged on one side of the operation panel, a video watching mode replaces an oral account mode of a teacher, enjoyment and motivation of students are improved,learning effects of the students can be deepened by simulation training, air is charged into the extinguishers through the inflation inlet and replaces carbon dioxide, the pressure sensors in the extinguishers monitor pressure in the extinguishers and view whether operations of the students are successful or not, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire fighting equipment demonstration device used in teaching. Background technique [0002] Fire Extinguisher──In ancient times, fire extinguishers were very simple, nothing more than hooks, axes, shovels, buckets and the like. The first real special fire extinguisher was invented in 1816 by Manby, a British captain and a Norfolk native. It was just two drums containing more than 1 liter of water and filled with compressed air. By the middle of the 19th century, the French doctor Gallier had invented a portable chemical fire extinguisher. Mix sodium bicarbonate and water in the cylinder, and use a glass bottle to hold sulfuric acid in the mouth of the barrel. When in use, the striker breaks the bottle to mix the chemicals, generate carbon dioxide, and press the water out of the barrel. In 1905, Professor Laurent of Russia invented a foam fire extinguishing a...

Problems solved by technology

[0005] The present invention proposes a fire-fighting equipment demonstration device used in teaching, which solves the problem that the fire-fighting teaching equipment in the prior art can only be explained by the teacher's dictation, and it is difficult to arouse the students' interest in learning, making the teaching efficiency low and unable to deeply understand what kind of primary What kind of fire extinguisher is used for fire; and if real fire extinguishers are used for teaching, it will cause a waste of resources
