Amphibian tank gun automatic drainage device

Abstract

The invention discloses an amphibian tank gun automatic drainage device, belonging to the technical field of guns; the automatic drainage device is used for draining the water entering in a gun barrel, wherein the water is from the splash caused by the bombing of a shell launched by enemy in the water adjacent to the tank or caused by the storm when an amphibian tank gun is in float-crossing sailing. In the invention, fatal accident caused by a condition that the gun cannot shoot since the water is taken in the gun barrel or a condition that the bore premature is caused by the rushed shooting since the water is taken in the gun barrel is overcome, the risk of the amphibian tank gun when shooting on the water is reduced, and the safety and battle effectiveness of the amphibian tank are improved; the device is provided with a drainage channel for communicating the internal and the external of the gun barrel; the drainage channel is opened to drain the water in the gun barrel at normal time, and is automatically closed by using gun pressure when the gun shoots so as to prevent high-temperature high-pressure gas from leaking to guarantee the performance of the gun.

Description

technical field [0001] The invention provides an automatic drainage device capable of timely removing accumulated water in a cannon barrel of an amphibious tank when sailing on water, and belongs to the technical field of cannons. Background technique [0002] At present, when the known amphibious tanks float and sail on the water, when there are relatively large waves or the shells fired by the enemy explode in the water near the tank, it is easy to arouse splashes, and the aroused splashes are likely to enter the gun barrel. Usually, because the gun barrel forms a certain elevation angle with the horizontal plane, the water entering the gun barrel will flow inward along the bottom of the inner wall of the gun barrel. According to the related literature "Knowledge is Power" (No. The title of the publication is KNOWLEDGEISPOWER) introduction: It has been proved by experiments that once more water enters the gun barrel, reaching about 1 liter, the cannon will not be able to ...

Problems solved by technology

[0002] At present, when the known amphibious tanks float and sail on the water, when there are relatively large waves or the shells fired by the enemy explode in the water near the tank, they are easy to Arouse water splashes, and the aroused water splashes are likely to enter the barrel. Usually, because the barrel and the horizontal plane form a certain elevation angle, the water entering the barrel will flow inward along the bottom of the inner wall of the barrel. According to the relevant literature "Knowledge is Power" (No. 8, 2008, author——Chen Yu, English name KNOWLEDGEISPOWER) introduction: It has been proved by experiments that once the water in the gun barrel reaches more than 1 liter, the artillery will not be able to shoot. It may cause the bomb to explode, the light one will make the artillery incapable of fighting, and the serious one may cause accidents of vehicle crashes and fatalities. Therefore, the risk of amphibious tanks shooting on water is extremely high. If we look at it from the perspective of combat, then May affect the completion of combat missions
