Description

Technical Field

[0001] The utility model relates to the technical field of rainfall training, and particularly relates to a projectile structure of a blank training shell. Background Art

[0002] Artificial precipitation, also known as artificial rain enhancement, refers to the process of artificially supplementing some necessary conditions for precipitation formation according to the principle of natural precipitation formation, promoting the rapid condensation or coalescence of cloud droplets into raindrops and falling to the ground. Generally, shells carrying catalysts are fired into the clouds by artillery to make the clouds precipitate or increase the precipitation amount, so as to relieve or alleviate farmland drought, increase the reservoir irrigation water volume or water supply capacity, or increase the power generation water volume, etc.

[0003] To improve the level, training is usually required. However, live ammunition training not only has high costs but also has some potential safety hazards. Therefore, during daily training or test firing after artillery maintenance, blank cartridges are usually used. The existing blank cartridges have an integral structure. During training, the entire projectile drops, and the integral projectile has a relatively long firing distance, and the dropped objects may cause damage to personnel, vehicles, and buildings. Content of the Utility Model

[0004] To solve the above problems, the utility model provides a projectile structure of a blank training shell, and the utility model is realized through the following technical solutions.

[0005] A projectile structure of a blank training shell includes a projectile body, a filler, and a bottom cylinder. The projectile body has a hollow structure, one end of the projectile body is tapered, and the other end of the projectile body is open. The filler is contained in the projectile body. The bottom cylinder is in interference fit with the open end of the projectile body. Preformed grooves are evenly arranged on the inner circumferences of the projectile body and the bottom cylinder. The projectile body and the bottom cylinder are integrally formed injection molded parts.

[0006] Preferably, a conical seat body is provided at one end of the bottom cylinder located inside the projectile body.

[0007] Preferably, spiral ribs are integrally formed on the outside of the projectile body.

[0008] Preferably, the filler is iron sand.

[0009] Preferably, the filler is a mixture of baking soda powder and citric acid powder. A cover cylinder is fixedly connected inside the bottom cylinder. The cover cylinder is densely provided with through holes. A rubber membrane bag is provided inside the cover cylinder, and water is contained in the rubber membrane bag.

[0010] The beneficial effects of the present utility model are as follows: In the present application, the projectile body adopts a hollow structure, and a filler is filled in the projectile body. Prefabricated grooves are provided inside the projectile body and the bottom cylinder. The overall structure of the projectile body and the bottom cylinder is fragile and is prone to breakage when pushed, and the projectile is also prone to breakage due to the existence of centrifugal force when rotating. When the projectile is launched, each part breaks quickly, so that the launch distance will not be too far, avoiding the increase in uncontrollability caused by too far a distance. The falling object breaks into smaller fragments, and the falling object will not cause injury to personnel, vehicles, buildings, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0019] Such as Figures 1-4As shown in the figure, a projectile structure of an empty-pack training projectile includes a projectile body 1, a filler 2, and a bottom cylinder 3. The projectile body 1 has a hollow structure. One end of the projectile body 1 is conical, and the other end of the projectile body 1 is open. The filler 2 is contained in the projectile body 1. The bottom cylinder 3 is press-fitted into the open end of the projectile body 1. Prefabricated grooves 4 are evenly arranged on the inner circumferences of the inner walls of the projectile body 1 and the bottom cylinder 3. The projectile body 1 and the bottom cylinder 3 are integrally formed injection molded parts.

[0020] Further, a conical seat body 5 is provided at one end of the bottom cylinder 3 located inside the projectile body 1.

[0021] Further, spiral rib strips 6 are integrally formed on the outside of the projectile body 1.

[0022] Further, the filler 2 is iron sand.

[0023] Further, the filler 2 is a mixture of baking soda powder and citric acid powder. A cover cylinder 7 is fixedly connected inside the bottom cylinder 3. Through holes 8 are densely arranged on the cover cylinder 7. A rubber membrane bag 9 is provided inside the cover cylinder 7, and water is contained in the rubber membrane bag 9.

[0024] The projectile body 1 and the bottom cylinder 3 are made of high-strength and high-impact nylon materials and are integrally injection molded. Prefabricated grooves 4 are provided inside the projectile body 1, ensuring easy breakage after launch.

[0025] During assembly, the weighed filler 2 is poured into the projectile body 1, and then the bottom cylinder 3 is pressed into the projectile body 1 using a hydraulic press. The bottom cylinder 3 and the projectile body 1 are press-fitted, and the projectile body 1 and the bottom cylinder 3 will not separate after assembly. The conical seat body 5 makes it easy for the head of the bottom cylinder 3 to enter the projectile body 1 before press-fitting, ensuring accurate positioning.

[0026] After launch, due to the existence of the spiral rib strips 6, the whole projectile rotates. Under the action of centrifugal force, the projectile is prone to break at the position of the prefabricated grooves 4, and the filler 2 is thrown out. Under the action of air resistance, each falling object drops, making the launch distance of the projectile not too far (usually falling within 100 meters of the muzzle), and the falling objects are small fragments, with a controllable distance and fragmented falling objects, so as not to cause injuries to personnel, vehicles, and buildings.

[0027] There are two types of fillers 2 in this application. One is iron sand.

[0028] The other is a mixture of baking soda powder and citric acid powder. As Figure 1 and 2 shown, when the projectile is launched, it generates heat by friction with the air, causing the rubber membrane bag 9 to expand and age due to heat, making the rubber membrane bag 9 damaged, and the water inside it flows out, causing the baking soda powder and citric acid powder to undergo a neutralization reaction to generate gas, thereby expanding the inside of the projectile and forcing the projectile to break.

[0029] The centrifugal force causes the projectile to break at the prefabricated groove 4, and the gas expansion can also cause the projectile to break. The double guarantee makes the projectile fragment, avoiding damage caused by too large falling objects.

[0030] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and variations can be made.
