Embodiment Construction

[0028] Such as figure 1 with figure 2 As shown, the device proposed by the present invention for measuring the equivalent diameter of blast holes includes a water tank, a water pump, a flow meter and a control valve.

[0029] There is an opening at the bottom of the water tank, and the aperture is larger than the maximum aperture of the hole in the target plate to be tested. The maximum aperture of the hole refers to the maximum value of the distance between any two points on the edge of the hole. An installation hole is provided on the edge of the opening at the bottom of the water tank, which can seal and fix the target board to be tested at the opening at the bottom of the water tank.

[0030] The upper part of the water tank has a water inlet and a water level marking line, and a water level control switch is arranged at the water level marking line on the upper part of the water tank; the water inlet of the water tank is connected to the water pump through a pipeline, a...

Abstract

The invention provides a device and method for measuring the equivalent diameter of an explosion broken hole. The device comprises a water tank, a water pump, a flow meter and a control valve. The method comprises the steps that standard target plates with different standard open pore diameters are installed at the open pore positions of the bottom of a water tank in a sealed mode respectively, flow testing is conducted, the corresponding relation between the different open pore diameters and flow in the standard target plates under the set duration is obtained, and a relation curve of the open pore diameters and flow of the target plates is fitted; and then the tested target plate is installed at the position of the opening in the bottom of the water tank in a sealed mode, flow testing isconducted, the flow under the set duration is obtained, and the corresponding target plate opening hole diameter is obtained by comparing the established relation curve of the target plate opening hole diameter and the flow and serves as the broken hole equivalent diameter of the tested target plate. The device is close to the actual working condition of the underwater weapon industry, easy to implement, reliable in work and low in use cost.

Description

technical field [0001] The invention relates to the technical field of blast hole measurement, in particular to a device and method for measuring the equivalent diameter of blast holes. Background technique [0002] The size of the hole formed by the jet or projectile formed after the explosion of the energy-shaping warhead on the target plate is an important quantitative parameter for the evaluation of the damage effect of the energy-shaping warhead. It is an important embodiment of the necessity of equipment development and the advancement of technology. Since the explosion is an extremely rapid energy release process, a huge impact load acts on the target target plate, causing the target plate to deform and warp while being torn or even broken, making the shape of the hole on the target plate extremely irregular. According to the rules, it is difficult to accurately measure the diameter of the hole in the target plate. [0003] In the early days, the requirements for co...
