Problems solved by technology

The disadvantages of the above patents are as follows: (1) The icebreaker bombs need to be arranged on the ice surface at a designated location. Without knowing the ice surface, the safety of the operators on the ice cannot be guaranteed
(2) The connection body is an aluminum alloy hollow cylinder, and the front-stage open-hole bomb is detonated on ice, and the shrapnel and connection body fragments are likely to pose a threat to the surrounding personnel
(3) The rear-stage blasting projectile enters under the ice under the action of its own gravity and the momentum of the front-stage open-hole projectile. It is difficult to control the depth of its entry into the water, and the blasting efficiency is uncontrollable

Abstract

The invention discloses an under-ice fixed-depth ice breaking bullet capable of being thrown automatically and based on a drone. The bullet comprises a bullet body, a floater, an inner end cover, an outer end cover, an explosion timer arranged in the inner end cover and a water-proof plug arranged on the outer end cover. A floater chamber matched with the floater is arranged on a lateral wall of the bullet body, the floater is arranged in the floating chamber to form a cylindrical whole body with the bullet body and fixed by a water-soluble ribbon, and the floater is connected with the bullet body through two fixed-depth ropes. Outer threads are arranged on a port of the bullet body, a flange is arranged at the open end of the inner end cover, the inner end cover is arranged at the port position of the bullet body, the outer end cover is in threaded connection with the port of the bullet body, and a sealing rubber ring is arranged between the flange of the inner end cover and the outer end cover. The bullet has the advantages of being small in size, light in weight, novel in design, simple in throwing, adjustable in delay, safe, reliable, large in explosive force, good in ice breaking effect and capable of conducting continuous throwing operation.

Description

technical field [0001] The invention relates to a sub-ice depth-fixed ice-breaking bomb based on the automatic delivery of a drone, which belongs to a diving ice-breaking bomb and is suitable for excavating a flow channel, breaking a large block of flow, and eliminating ice plugs and ice dams. Background technique [0002] The Chinese patent discloses a kind of "A Kind of Icebreaker" (Application No.: 200920207158.0), which includes a front-stage opening bomb, a connecting body, a rear-stage blasting bomb, a comprehensive socket and a cable, etc. The under-ice blasting is integrated, and the front-stage detonator and the rear-stage detonator are respectively connected to the integrated socket through cables, which can realize long-distance detonation. The disadvantages of the above-mentioned patents are as follows: (1) The icebreaker bombs need to be placed on the ice surface at a designated location. Without knowing the ice surface, the safety of the operators on the ice ca...
