Detailed Description

The invention relates to a water target channel underwater gun position subsection structure which is used for realizing underwater high-speed projectile launching experiments. The invention can realize underwater high-speed projectile launching experiment. The underwater gun position segmented structure resists recoil force generated when the gun seat is launched through the self weight of the reinforced concrete bottom plate and the side wall; through the water collecting well and the inserting plate door which are arranged in the gun seat section, when the artillery needs to be subjected to loading operation, the inserting plate door is closed, water in the underwater gun position section is discharged, and when the artillery needs to be launched, the inserting plate door is opened, so that the shots can be launched underwater; through the expansion joint and the gravel shock insulation ditch outside the lateral wall that set up between with the water target way, reduce the big gun seat vibrations when launching and to the influence of high-speed camera system under water in the water target way to guarantee the experiment required precision.

The invention is further described below with reference to the accompanying drawings.

The underwater gun position subsection structure of the water target channel is used for underwater high-speed projectile launching experiments, and water overflows the whole gun position structure when the underwater high-speed projectile launching experiment is used.

As shown in fig. 1 and 2, the gun position structure is underground, the main body is formed by connecting two parts, namely a water collecting well and a water target, wherein the left water collecting well comprises a reinforced concrete base, a side wall 1 and a water outlet 2; the right water target way comprises a spile door 3 and a target way 6. Gravel shock insulation ditches 5 are arranged between the whole gun position structure and the outer side of the water target way and the ground, and gravel is filled in the gravel shock insulation ditches.

As shown in fig. 1 and 2, the collector well is a rectangular structure, and the base and three walls of the collector well are poured by reinforced concrete, and the side opposite to the water target way is left vacant.
