Description

Ice-cold device for cannon barrel

Technical Field

The utility model relates to a weaponry development field, concretely relates to artillery barrel ice-cold device.

Background

Barrels are the most basic components of artillery, which bear high temperature and high pressure gunpowder gases and eject the projectiles at high speed when fired. To prevent the barrel from overheating, cooling measures may be taken on the barrel to increase the artillery firing rate and extend the life of the barrel. At present, naval cannons utilize seawater to cool the outer surface of a barrel. China army artillery has to limit the shooting speed because no barrel cooling measures are taken. The method for cooling the barrel of a few foreign army artillery adopts a method of sleeving a water jacket on the outer part of the barrel.

The barrel is cooled by adopting a method of a water jacket outside the barrel, when the temperature of water in the water jacket reaches the boiling point of water, the water jacket loses the cooling effect, and the cannon must stop shooting. Such cooling devices have limited utility.

Further, the controller is connected with the buzzer through a cable.

The beneficial effects of the utility model reside in that: the utility model provides a cannon barrel ice-cold device sets up cooling sleeve in the barrel outside, pack into the ice-cube in the cooling sleeve, replace water as barrel coolant with ice, because can absorb some barrel heat from ice to water, can absorb some barrel heat again from ice water to boiling water, so the ice-cold scheme is bigger than the cooling effect of water-cooling scheme to the barrel on the whole, can make the cannon shoot longer time in succession, and prolong barrel life-span to a certain extent.

The utility model discloses a cannon barrel has installed ice-cold device additional, can follow the barrel and absorb more heats to help improving cannon shooting speed and extension barrel life-span, can be used to the cannon development of colleges and universities, scientific research institute and weapon manufacturing factory.

Detailed Description

Referring to fig. 1, a device for cooling a barrel of a cannon by ice comprises a barrel 1, a cannon tail 2 arranged at the tail end of the barrel 1 and a breech 3 arranged at the cannon tail 2; the barrel 1 comprises a guide part 5 and an extension part 6; the guide part 5 is movably connected with the cradle 7. The extension portion is a portion that does not engage with the cradle, and is located in front of the guide portion (forward in the muzzle direction).

A cooling sleeve 8 is sleeved outside the extension part 6, the bottom edge of the cooling sleeve 8 is perpendicular to the axial direction of the barrel 1, and an annular ice discharging opening 9 is formed in the muzzle 4; the ice discharging opening 9 is provided with a blocking cover; the baffle cover comprises an upper half-screw ring cover 10 and a lower half-screw ring cover 11; the outer sides of the upper half ring cover 10 and the lower half ring cover 11 are provided with external threads, the inner side of the annular ice discharging opening is provided with internal threads matched with the external threads, and the inner sides of the upper half ring cover 10 and the lower half ring cover 11 are provided with sealing ring gaskets 12. The ice discharging opening is sealed by matching the upper semi-spiral ring and the lower semi-spiral ring with the front end of the cooling sleeve through threads, and the sealing ring gasket is sealed with the barrel.

A drain pipe 13 is arranged on the lower side of the bottom edge of the cooling sleeve 8, a drain valve 14 is arranged on the drain pipe 13, and a temperature sensor 15 is arranged in the inner wall of the lower side of the cooling sleeve 8; the cooling sleeve 8 is filled with ice blocks.

The drain valve 14 is a solenoid valve. The drain valve 14 and the temperature sensor 15 are connected with a controller 17 through a cable 16. The controller 17 is connected to a gun power supply 18 via a cable 16. The controller 17 is connected to a buzzer 19 via a cable 16. The controller is provided with an ice-releasing button and a water-releasing button.

The working principle is as follows: before the cannon is shot, the upper hemivolution ring and the lower hemivolution ring are screwed off, the barrel is slightly lifted, crushed ice blocks are filled in through an ice discharge port (the cannon is matched with a refrigerator car and an ice crusher to be used in actual operation), and then the upper hemivolution ring and the lower hemivolution ring are screwed on.

In the continuous shooting process of the artillery, the barrel heats, the heat of the barrel is absorbed by the ice blocks, the ice blocks are firstly melted into ice water, and then the temperature of the ice water is continuously raised. The temperature sensor is used for measuring and timely displaying a temperature value on the display panel of the controller, when the temperature value is too high and reaches a set value, the controller drives the buzzer to give an alarm, and the cannon stops shooting.

At the moment, in order to enable the artillery to quickly enter a shooting state, a gun barrel is struck, a small barrel is placed below a drain pipe, a 'water discharge' button on a controller is pressed, the controller opens a drain valve, and high-temperature water in a cooling sleeve is discharged into the small barrel through the drain pipe.
