Embodiment Construction

[0028] Such as figure 1 and 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, an...

Abstract

The present invention proposes a device and method for measuring the equivalent diameter of blast holes. The device includes a water tank, a water pump, a flow meter and a control valve; the method is to seal and install standard target plates with different standard hole diameters on the bottom of the water tank respectively. The location of the opening, and the flow test is carried out to obtain the corresponding relationship between the different opening apertures and the flow rate in the standard target plate under the set time length, and the relationship curve between the opening aperture and the flow rate of the target plate is fitted; then the tested target plate is sealed It is installed at the opening position at the bottom of the water tank, and the flow test is carried out to obtain the flow rate under the set time length. By comparing the relationship curve between the established hole diameter of the target plate and the flow rate, the corresponding hole diameter of the target plate is obtained as the target plate. Measure the equivalent diameter of the hole on the target plate. The invention is close to the actual working conditions of the underwater weapon industry, and is easy to implement, reliable in operation 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...
