Problems solved by technology

Since the simulated deep water environmental explosion test needs to simulate different water depth environments or meet the requirements of different explosive equivalents in closed containers, the compression resistance and sealing performance of the existing test cable sealing devices are increasingly unable to meet the test requirements.

Abstract

The invention relates to a testing cable sealing device for a container for simulating a deepwater environment explosion test. According to the technical scheme, two to fifteen cable holes (8) are formed around the center of a flange cover plate (1) and located in a protection cover (2); each cable hole (8) is a through hole which is formed by three sections, the hole diameter of the upper portion is larger than the hole diameter of the lower portion, a sprue (7), sealant (6) and a ring washer (5) are concentrically arranged on the middle section of each cable hole (8) from bottom to top, each compression bolt (4) is fixedly connected with the upper section of the corresponding cable hole (8) through threads, and the lower end of each compression bolt (4) is tightly pressed on the upper plane of the corresponding ring washer (5); a testing cable (3) sequentially penetrates through the protection cover (2), the corresponding compression bolt (4), the corresponding ring washer (5), the corresponding sealant (6) and the lower section of the corresponding cable hole (8) to be connected with an underwater impact wave pressure sensor. The testing cable sealing device is high in compression resistance, good in sealing performance, easy to assemble, wide in application range, and capable of meeting the requirement for simulating the 0.01-Kg TNT equivalent explosion test at the 200 m underwater environment.

Description

Technical field [0001] The invention belongs to the technical field of simulated deep-water environment explosion tests. Specifically, it relates to a test cable sealing device for simulating a container for explosion test in a deep water environment. Background technique [0002] Based on the research of underwater explosion theory, it lags far behind the development of engineering practice technology, and a lot of underwater explosion simulation tests are needed. When using a closed container to simulate an explosion test in a deep water environment, the underwater shock wave pressure sensor is placed in the closed container, and the signal generated at the moment of the explosion captured by the sensor is transmitted to the data acquisition instrument outside the closed container through the test cable. The closed container is filled with water. Medium, and the internal pressure is high, the tightness of the lead-out part of the test cable directly affects the success or fail...
