Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a new type of device for measuring the explosive characteristics of liquid after falling. When the device is used to measure the explosive characteristics of liquid after falling, it can well meet the requirements of GB / T21581- The technical requirements of the 2008 "Drop Test Method for Liquid Steel Pipes of Dangerous Goods", such as steel pipe inner diameter 33mm, outer diameter 42mm, length 500mm, the maximum height that the steel pipe can rise on the lifting platform is 5m (0.5m as a grade), etc. In the process of measuring the explosive characteristics of the liquid after falling, the device realizes remote automatic control, which changes the situation that the entire experimental process must be operated by hand in the past, and effectively improves the safety factor of the test.

Abstract

The invention provides a device for measuring the explosion characteristic of fallen liquid. The device comprises a sample accommodating device for accommodating a sample to be tested, a fixing device for fixing the sample accommodating device at a position required in the test, a positioning device for positioning the fixing device and the sample accommodating device, an automatic lifting device for lifting the sample accommodating device, an automatic releasing control device for releasing and dropping the sample accommodating device from the fixing device and a protection device for preventing danger caused by the explosion of the fallen sample to be tested. A lifting table of the device is automatic; the device is provided with a creepage protection device and a blasting protection device as well as an automatic releasing device, so that an operator can get away from a test site, and operates the test through a wireless remote control device; therefore, remote automatic control is realized; and the safety coefficient of the test is increased.

Description

technical field [0001] The present invention relates to a device for measuring the properties of liquids, in particular to a device for measuring the explosive properties of liquids after falling. Background technique [0002] Chemical energetic liquids (or other chemicals) are generally prone to accidents. When they are subjected to external conditions such as friction, impact, fire, and heat during loading and unloading, major accidents such as explosions or fires are likely to occur. Once an accident occurs during storage and transportation, it will cause huge losses to life and property. Therefore, it is necessary to determine the explosive properties of the object after being dropped before storage and transportation. At present, the accuracy of the device for measuring the explosive characteristics of liquid after falling is low, and it is difficult to meet the technical requirements of GB / T21581-2008 "Dropping Test Method of Liquid Steel Pipe for Dangerous Goods". T...
