Novel breaking-explosion type efficient ice breaking device

Abstract

The invention provides a novel novel breaking-explosion type efficient ice breaking device. The device comprises a preceding-stage annular shaped charge and a backward-stage ordinary charge; the preceding-stage annular shaped charge comprises a preceding-stage shell, a preceding-stage grain, a shaped charge cover and a preceding-stage initiating device, the preceding-stage grain is arranged in thepreceding-stage shell, and the shaped charge cover is arranged at the front end of the preceding-stage grain; the preceding-stage initiating device is arranged at the rear end of the preceding-stagegrain; the rear-stage ordinary charge comprises a rear-stage shell, a rear-stage grain and a rear-stage initiating device; the rear-stage grain is arranged in the rear-stage shell, and the rear-stageinitiating device is arranged at the rear end of the rear-stage grain; and the preceding-stage annular shaped charge is arranged directly in front of the rear-stage ordinary charge. According to the novel breaking-explosion type efficient ice breaking device provided by the invention, after efficient super-caliber penetration of the preceding stage to an ice layer is achieved mainly through two-stage series connection, the backward-stage explosive enters the position below the water surface to explode, and therefore the effect of underwater ice layer blasting is achieved.

Description

technical field [0001] The present invention relates to the technical field of ice breaking device design, in particular to a new type of breaking-explosion high-efficiency ice breaking device. Background technique [0002] During the alternation of winter and spring in the northern region, the temperature difference between the upper and lower reaches of boundary rivers and inland rivers is large, and it is easy to accumulate and form dam-like ice bodies, causing dams to burst and forming ice disasters. At present, the commonly used explosive ice-breaking methods mainly include ice-charge blasting, shell explosion ice-breaking and under-ice charge blasting. For ice-charge blasting, on the one hand, air explosions are likely to cause secondary damage to surrounding buildings; on the other hand, air explosions The power of the explosion is less than that of the underwater explosion, and the ice-breaking effect is greatly impaired. For shell explosion ice breaking, the concen...
