A high-precision explosion source location device for offshore platform tests

Abstract

The invention provides an offshore platform test high-precision explosion source positioning device. The offshore platform test high-precision explosion source positioning device comprises a fixed sliding rail mounted on the outer wall of a floating impact platform, an upper end sliding block, a lower end sliding block, a moving positioning block, a rotating block, a first-stage connecting cylinder, a first-stage stretching rod, a connecting part, a turnover fold plate, a secondary connecting cylinder, a secondary stretching rod and an end mounting device; the upper end sliding block, the lower end sliding block and the moving positioning block are arranged in the fixed sliding rail from top to bottom, the rotating block is arranged between an upper end fixing block and a lower end fixing block through an end plug pin, the first-stage connecting cylinder is hinged to the rotating block, the first-stage stretching rod is connected with the end of the first-stage connecting cylinder, the connecting part is arranged at the end of the first-stage stretching rod, the turnover fold plate is hinged to the connecting part, the secondary connecting cylinder is connected with the end face of the fold plate, the secondary stretching rod is connected with the end of the secondary connecting cylinder, and the end mounting device is arranged at the end of the secondary connecting cylinder. The offshore platform test high-precision explosion source positioning device is simple in structure, convenient to mount and low in production cost, the device is characterized in that in the test on the floating impact platform, the accurate positioning of an explosion source is achieved, and meanwhile, the explosion source positioning device can be repeatedly dismounted and mounted.

Description

technical field [0001] The invention relates to a high-precision explosion source positioning device for offshore platform tests, belonging to the technical field of impact-resistant assessment tests for ship equipment. Background technique [0002] With the development of my country's naval technology and the increasing emphasis on marine affairs, my country has continuously increased its investment in research and development and production of naval equipment, and naval equipment often needs to conduct verification experiments of many performance parameters before it is officially delivered for use. Among the contents of the assessment, the assessment of its response to the underwater explosion attack is an important content. However, it is impossible to evaluate the explosion shock response of equipment on ships with actual ship tests. Some small equipment (light in weight) can be assessed by land impact machines. For large and medium-sized shipboard equipment, floating im...

Problems solved by technology

In this case, due to the distance of the location of the explosion source, the slender rod has a large deflection problem, resulting in inaccurate location; at the same time, during the experiment, the location device is often broken due to the impact load of the explosion, so In each experiment process, it is necessary to repeatedly install the positioning rod, which not only increases the cost of the experiment, but also makes it very inconvenient to operate at sea

Therefore, the purpose of this device is to provide a high-precision mechanical positioning device for the offshore explosion shock test of the floating shock platform, and at the same time solve the problems of non-reusable and complicated operation in the traditional mechanical positioning device, and improve the operability of the offshore explosion test confidence in sex and test results
