Automatic test device forflame retardant property of firefighter protective boot and use method

Abstract

The invention provides an automatic test device for the flame retardant property of a firefighter protective boot and a use method.The test device comprises a cantilever beam, a foot model is hoisted under the cantilever beam, a protective boot sample is worn outside the foot model, moving devices are arranged under the protective boot sample, the tail end of each moving device is connected with a combustor, flaming ports of the five combustors are respectively opposite to the upper surface of the front end of the protective boot sample, the junction of the front end of the protective boot sample and the boot sole, the position under the boot sole of the protective boot sample, the position right in front of the boot leg of the protective boot sample and the position right behind the boot leg of the protective boot sample. The combustors are supported by a mechanical structure, flame shaking can be prevented, it is ensured that the inner flame tip of the flame makes contact with a sample, the distance is kept stable, the requirement that the flame inclines by 90 degrees or 45 degrees is met, timing, observation and judgment are all automatic, the environment where detection personnel are located is improved, and the test detection quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting product testing equipment and methods, and in particular relates to an automatic test device for the flame-retardant performance of firefighter protective boots and a method for using it. Background technique [0002] Now the flame retardant performance test of fireman's protective boots is carried out manually by hand-held Bunsen burner operation. The protective boots sample is placed on the bench, and the burner is ignited to adjust the flame height to 75mm. The flame is 90 ° or 45 ° against the protective boots. The sample stipulates that five burning points should be left after contacting and burning for 12s. The self-extinguishing time of each burning position after leaving the fire should not exceed 2s. The damage length of each test position should not exceed 100mm, and there should be no melting, dripping or peeling. . Because the hand-held Bunsen burner is operated by hand, it is e...

AI Technical Summary

Problems solved by technology

Because the hand-held Bunsen burner is operated by hand, it is easy to cause the flame to shake, and the angle and distance between the flame and the burning point are difficult to meet the specified requirements, which also makes the burning temperature of each test burning point inconsistent. This is because the outer flame and the inner flame part of the fire It is not as stable and high as the temperature of the inner flame tip. Each burning point burns for 12s and leaves the fire. The self-extinguishing time of the burned point does not exceed 2s. There are often deviations in timing, observation, and judgment by human eyes. The quality of the test is tested. The efficiency and efficiency are not high, and the environment in which the inspectors are located is also harsh
