Floating body platform capable of carrying out underwater explosion damage test in large water area

Abstract

The invention discloses a floating body platform capable of carrying out an underwater explosion damage test in a large water area, which can reduce the influence of environmental factors, improve thetest precision and research underwater explosion and damage problems. A hanging bracket is installed in the middle of the floating body platform body, one end of the hanging steel cable is fixed to the hanging bracket, and the other end penetrates through a notch in the floating body platform body below the hanging bracket to be connected with the target. A lifter is used for controlling the lifting steel cable to put down and recover the target; the length of the hoisting steel cable is slightly greater than the specified detonation depth, so that the hoisting steel cable is not stressed during test detonation; one end of the bearing steel cable is fixed on the floating body platform body and the other end is connected with the target; the length of the load-bearing steel cable is set according to the specified detonation depth for controlling the underwater penetration depth of the target and bearing the gravity of the target during test detonation; one end of the restrictive detonating cord is fixed to the floating body platform body, and the other end of the restrictive detonating cord is connected with a test detonation source arranged on the target. The floating body platform body is connected with N anchoring buoys at equal intervals to limit movement and rotation of the floating body.

Description

technical field [0001] The invention belongs to the technical field of underwater explosion and damage tests, and in particular relates to a floating body platform capable of carrying out underwater explosion damage tests in large water areas. Background technique [0002] With the rapid development of underwater weapons, the underwater explosion test of ammunition, as an important research method, is gradually systematized in practice. For underwater explosion damage tests, most of them are done in wells, pools or tanks. The test environment is relatively limited, which also limits the scale and accuracy of the test to a certain extent. In order to more realistically simulate the actual combat environment, it is necessary to carry out experiments in large waters such as seas (lakes). [0003] However, carrying out experiments in large waters is costly and there are many uncontrollable factors. There is no special test platform in the prior art. Most of the test devices su...

[0003] However, carrying out experiments in large waters is costly and there are many uncontrollable factors

There is no special test platform in the prior art, and most of the test devices such as the warhead and the target are installed, and then directly hoisted into the offshore or directly dragged to a predetermined position for testing. The lack of large-scale platform support makes the operation inconvenient and unfavorable The positioning of the test device, the test device may rotate or shift under the influence of environmental factors, and the depth of water entry cannot be well controlled, resulting in errors in test data collection and greatly affecting test accuracy; The target cannot be recovered normally due to excessive load-bearing. Therefore, a reasonable design of a floating platform that can carry out underwater explosion damage tests in large water areas can provide platform support for underwater explosion tests in large water areas. The explosion damage test is of great significance
