Description

The utility model relates to military defensive structures used in the engineering equipment of the positions of troops, block of posts, watchposts, border sections and other important objects to ensure their effective protection and defense in the shortest possible time without significant material costs.

Known prefabricated fortified structure of the closed type for firing ZSM-1, - analogue ("Recommendations for the use of prefabricated fortifications for firing UFS-4 with metal closures ZSM-1, ZSM-2 and ZSM-3" M., 1985, pg. 21-21), consisting of a base, a support element, a rotating disk with a cover, lifting (lowering) mechanisms and a device for attaching weapons.

The disadvantages of this technical solution are the large weight and size parameters and the complexity of the construction (extraction), low transport characteristics, the long preparation time of the firing position, the complexity of repeated use and high cost.

Known machine gun metal structure SPM-2 (4), a prototype ("Military fortifications", Military Publishing, M. .., 1984 p. 50), consisting of an entrance, a base and a turret equipped with an embrasure with a shutter and a wall mounted machine gun the machine tool.

The disadvantages of this technical solution are the low combat effectiveness due to the impossibility of using various types of small arms, the large mass, the high complexity of the erection (extraction), low transport characteristics, the long preparation time of the firing position, the complexity of repeated use.

The objective of the proposed technical solution is to increase the tactical and technical characteristics by reducing weight, the complexity of the firing position, improving the conditions for observation and firing of various weapons, reducing the level of gas contamination in the structure, achieving the possibility of a quick change of firing position, as well as reducing the cost.

The solution to this problem is achieved by the fact that in the proposed protective observation and fire structure, consisting of an entrance, a base and a turret equipped with an embrasure with a shutter and a wall machine gun, the turret is made of composite materials and has a hole in the center of the structure reinforced with a flange with a closed sliding bearing and a fragment of the pendulum tube, to the upper part of which a beam is attached for mounting various small arms and a protective bulletproof shield, - lower a stand with a seat for the shooter is attached, and a periscope sight is fixed in the center, while for the convenience of combat work, slots for observation are provided on the sides of the embrasure.

The essence of the proposed utility model is illustrated by drawings, which depict: in Fig.1 - shows a top view of a protective observational-fire structure, erected on the ground; figure 2 shows a longitudinal section of the structure in position for observation or shooting; Figures 3 and 4 show, respectively, transverse and longitudinal sections of the rotation mechanism (tilt) of the weapon and the associated periscope sight; figure 5 shows a set of components of the tower together with their fasteners, prepared for the assembly of the structure or its transportation.

Protective observation and fire structure (Figs. 1-5), consists of an entrance, a base and a turret 1 equipped with an embrasure with a shutter 2 and a wall mounted machine gun, the turret 1 is made of composite materials and has an opening 3 in the center of the structure, reinforced with a flange 4 with a closed sliding bearing 5 and a fragment of a pendulum pipe 6, to the upper part of which a beam 7 is attached for mounting various small arms 8 and a protective bulletproof screen 9, a stand 10 with a seat 11 for the shooter is attached from below, and in the center is fixed a periscope sight 12, while for the convenience of combat work, slots for observation 13 are provided on the sides of the embrasure.

The shooter conducts observation and firing in the circular sector, sitting on the seat 11 (figure 2) using a periscope sight 12, which is paired and shot together with the weapon 8. The rotation of the weapon with the periscope in any direction is achieved due to the sliding bearing 5, which under by the force of the legs of the shooter, applied to the seat 11, by means of the strut 10 and a fragment of the pendulum tube 6, it moves in the desired direction. The inclination of the weapon up or down is achieved by turning the pendulum pipe 6 when moving the rack 10 (Fig.2, 4) together with the seat 11 arrow forward or backward. For additional protection of the shooter from being hit by enemy return fire, a screen 9 (Figs. 1, 2) in the form of a light curtain made of bulletproof material is fixed in front of the traverse. When a bullet hits, it almost completely loses its energy due to the ductility and high strength of the material.

Replacing weapons, reloading the magazine to a machine gun or firing a grenade launcher is carried out without going to the surface by using the opening of the embrasure 2 when the corresponding weapon is turned to it, with the necessary side and with the desired angle. For greater security, such an operation is carried out from the back of the tower. When the ammunition supply is exhausted during the battle, the periscope or rotary device is damaged, the shooter uses the embrasure 2 to fire from the machine gun (machine gun) and the slit 13 for observation. In this case, the stand 10 together with the seat 11 is removed, and for observation and firing in the circular sector of the shooter, using the brackets 14, manually rotates the tower 1 in the desired direction.

To erect a protective observational-fire structure (Figs. 1, 2), a trench of an incomplete profile, 110-120 cm deep, is first set up. Then a tower made of composite materials is manually installed on its walls, while the adjacent section of the trench (or entrance to in the form of a manhole) overlap with improvised material and mask. After that, a traverse 7 with a protective shield 9 is attached to the tower from above, a periscope sight 12 is installed and the weapon is mounted on fixed sockets, and a stand 10 is attached from below with a seat 11 for the shooter.

To reuse the tower kit 1 or transport it to another war zone, the weapon 8, periscope 12 and traverse 7, as well as the stand 10 together with the seat 11 are removed from it. After that, the tower is removed and transferred to a new location with a calculation of three or four people .

Tower transportation can be carried out by any means of transport at any distance, including the airborne landing method. For mechanized loading (unloading) towers are stacked on a pallet in several sets (figure 5).

Concealment of a structure at a firing position is achieved by applying to the tower surface a special radio-transparent (radio-absorbing) coating made of composite material, using tree branches, bushes and installing one link of a service camouflage kit. In this case, firing from a machine gun can be done through a camouflage coating, without removing it.

The readiness of the proposed technical device for pilot testing is confirmed by the presence of drawings and calculations confirming the feasibility of the adopted constructive solution, the possibility of manufacturing a working layout using domestic innovative materials.

The proposed technical solution in comparison with known analogues has the following advantages:

- high combat effectiveness due to the possibility of using various types of small arms;

- the convenience of combat shooter using a rotating seat, periscope sight and sight slots;

- lack of gas contamination of the structure when firing from the outside of the tower;

- increase the protection of the shooter from the response of fire by the device bulletproof screen;

- mobility, ease of carrying and transportation;

- minimum labor costs for the construction of a firing structure;

- the ability to reuse the tower kit for quick equipment firing position;

- minimum weight and size parameters;

- low cost of design.

Theoretical studies and calculations show that the proposed protective observational-firing structure, according to the main criterion for assessing "application efficiency - cost", has indicators that are about 2-3 times higher compared to existing analogues.
