Ice breaking device

Abstract

The invention provides an ice breaking device which is suitable for manual ice breaking after a large area of water surface is frozen. The ice breaking device comprises a delivery system, a scattering system and an ice breaking element system. The delivery system comprises a rocket engine and an underwater movable parent projectile body. The scattering system comprises an extension pipe and scattering reagents. The ice breaking element system comprises independent sub projectile bodies which are symmetrically embedded in the two sides of a parent projectile shell of the underwater movable parent projectile body. The delivery system can move in the water under ice to be away from an initial operation area and scatter the ice breaking element system in the direction parallel to the ice surface under the action of the scattering system after reaching a determined area and conduct explosion for ice breaking. The ice breaking element system generates pushing force through the structure of the ice breaking element system to move in the water at random to explode to increase the ice breaking area. According to the ice breaking device, the parent and sub projectile scattering principle is adopted, and the ice breaking device is away from the initial operation area, and is simple in structure, easy to operate, high in safety, large in breaking area, obvious in ice breaking effect, and low in environment pollution, and lowers production difficulty and cost.

Description

technical field [0001] The invention belongs to the field of ice-breaking device design, and in particular relates to an ice-breaking device suitable for artificial ice-breaking after large-area water surface freezes. Background technique [0002] Due to the expansion of my country's territory, the temperature difference between the north and the south is relatively large. Especially in the winter in the north, the gradient of the temperature difference between day and night is huge, so that the water surface of the big rivers and rivers flowing through here will freeze. With the increase of freezing, the water flow in the riverbed will be affected The blocking effect is generated, so that the river section where the freezing occurs forms a frozen dammed lake phenomenon. When the temperature becomes high, the accumulated water flow after the freezing is lifted instantly will cause disastrous consequences to the downstream. Therefore, many technicians are trying to find a meth...

Problems solved by technology

There are three most widely used methods: After artificially laying explosives at fixed points on the ice surface, the relevant detonation circuit is used to carry out network blasting to break the ice. The disadvantage is that the rate of explosives deployment on the artificial ice surface is low. In order to fix the explosives, they are basically in the ice layer and the explosives explode. The energy generated in the end does not fully act on the ice layer, and the broken ice cubes generated at the same time splash around at a high speed, which is prone to safety accidents; Relying on helicopters to drop blasting bombs for ice breaking has the disadvantages of high cost, difficulty in launching, low accuracy of launching, and also easy to produce fragments, which pose a threat to the surrounding environment and the safety of personnel; Ice breaking is carried out by professionals using mortars to throw blasting mortars. The disadvantage is that fragments are generated, the utilization efficiency of explosive detonation is low, and operators require special training.

[0003] In order to overcome the shortcomings of the above-mentioned technologies, the present invention provides a new type of ice breaking device with a larger blasting area and safer use
