Problems solved by technology

Such a high price limits the use of sensors with water-cooled structural heat sinks
Moreover, all sensors currently on the market do not have a standard positioning device, and cannot accurately aim at the center of the measured object in the external fire test of the United Nations explosives [Test 6 (c)]. In the test, the measurement results are often inaccurate and affect the measured object. Judgment of the hazard level of the measured object

Abstract

The invention discloses a water-cooled heat flux meter sensor bracket for an external bonfire test of an explosive and belongs to the field of sensor brackets. The water-cooled heat flux meter sensorbracket disclosed by the invention comprises a base, a sight bracket, a water cooling head, a sensor and a laser flashlight; a water cooling module slot is formed in one end of the base; the sensor isfitted to the water cooling head, and the sensor and the water cooling head are integrally mounted on the water cooling module slot of the base; two sides of the water cooling module slot are provided with a connecting blot; one end of the sight bracket is provided with a connecting pothook; the connecting pothook and the connecting bolt are matched with each other to connect the base and the sight bracket together; and the laser flashlight is mounted on the sight bracket. The invention provides the water-cooled heat flux meter sensor bracket which is capable of meeting the operation requirement for the external bonfire test of the explosive in a test and criteria manual of united nation recommendations on the transport of dangerous goods, also realizing the sighting of a tested object and improving the accuracy and reproducibility of the external bonfire test of the explosive.

Description

technical field [0001] The invention belongs to the field of sensor brackets, in particular to a water-cooled sensor bracket used for external fire tests of explosives Background technique [0002] The United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part I, Section 16.6, specifies the external fire test [Test 6(c)] method for classifying explosives, which is used to determine when an explosive is involved in a fire. Whether there is a mass explosion or risk of hazardous projections, radiant heat and / or violent combustion or any other hazardous effect. In this experiment, it is required to evaluate the heat flux at a distance of 5m and 15m from the center of the explosive, and the evaluation results are used to determine the hazard level of the object under test. [0003] Most of the sensors currently used are thin-film sensors. The principle of this type of sensor is: infrared radiation causes the temperature of the infrared...
