Description

Underwater nail gun is a hand tool and device for driving nails initiated by the explosion of a charge.

Known is the USSR patent SU 108213A1. A gun for driving fasteners using the energy of powder gases, the body of which carries the trigger mechanism and is connected to a rotating barrel, equipped at the end with a tip protecting against fragments for applying to the place of fastener seating. The gun consists of a barrel, a body with a trigger mechanism placed in it. The barrel is made to rotate around the axis in order to load the gun with a fastener and a powder cartridge. At the free end of the barrel there is a replaceable tip, pressed against the place of fastener seating and protecting workers from fragments. The tip is connected by a flexible rod to the trigger mechanism safety catch.

The main disadvantage is the mechanical initiation system, which does not provide high tightness, which does not allow the device to be used for work under water and in aggressive aquatic environments.

The disadvantage is that the device is single-charge.

The Russian patent RU 2310805 C1 presents a multi-barrel shooting module, which contains a block of barrels for loading with cartridges, a barrel channel locking unit and a contact block for transmitting an electrical signal to electric caps.

The main disadvantage of the prototype is the presence of a locking unit, which reduces the tightness and reliability of the device when used in work related to the aquatic environment.

The disadvantage is the presence of a movable bushing in the clip, located between the electric cap and the cartridge. Also, the presence of the cartridge cap is unnecessary, since it receives a mechanical impulse from the powder gases when the electric cap is ignited. The presence of such intermediate parts generally reduces the reliability of the design.

The disadvantage is the lack of indication of the barrels being ready to fire.

The device is known - the Heckler Koch HK P11 pistol (Unique small arms: illustrated reference book / Ardashev A.N., Fedoseyev S.L. - M .: Astrel: ACT, 2006 - 319 [1] p: ill. - (Military equipment) pp. 171-173), designed for combat operations under water, where conventional bullets lose their effectiveness at a distance of about one meter, or even less, depending on the depth. Therefore, special ammunition with a nominal caliber of 7.62 mm was developed for the P11, firing long needle-shaped bullets that stabilize well in water. The mass of the arrow-shaped bullet is 31 grams, the length of the bullet is 117 mm. The initial velocity is 117 m / s. Ammunition is factory loaded into five-shot barrel blocks, which are installed on the frame of the weapon with a pistol grip. After all 5 charges have been fired from the barrels, the barrel block is removed and discarded, or saved for subsequent return to the factory for reloading (if shooting was conducted under training conditions). The charges are ignited electrically, the power source (two 9-volt batteries) is located in a sealed compartment in the pistol grip. The effective firing range is up to 15 meters underwater and up to 30 meters in the air. The gun body and barrel block casing are made of impact-resistant plastic.

The main disadvantage of the analogue is that it does not provide for shooting dowels for carrying out repair work.

The disadvantage is the lack of a safety device, which does not allow firing without tightly pressing the device to the object to be pierced.

The disadvantage is the inability to monitor the battery charge status.

The closest technical solution to the proposed one, taken as a prototype, is the underwater tool with a power drive US 3370770A, using a disposable barrel element, including a thin-walled tube containing a dowel and a cartridge. Both ends of the barrel element, as well as the primer of the cartridge, are sealed against water ingress. The barrel element is located in such a way relative to the body of the tool that the barrel element must be moved relative to the body of the tool in order to move it to the firing position. The means of firing the tool include a lever element, which, when rotated in one direction, cocks the striker, and when rotated in the other direction, releases the striker to activate the cartridge.

The main disadvantage is the mechanical initiation system, which does not allow for high tightness, and as a result, the possibility of long-term storage of the product. The problem of leakage of the pyrotechnic system can lead to dampening of the powder charge, misfire.

Another disadvantage is that the device is single-charge.

The disadvantage is the low speed of dowel fastening – 4 pcs/min.

The disadvantage is the presence of water hammer when firing.

The technical problem that the present invention is aimed at solving is to increase the reliability and functionality of an underwater assembly gun for driving in dowels by adding an optical initiation system to the device, which ensures the tightness and reliability of the device, as well as the possibility of installing a larger number of barrels.

The solution to the technical problem is achieved in that the underwater assembly gun for driving in dowels contains a hermetic body-handle, a release button, a push-button safety device made in the form of a spring-loaded rod. The underwater assembly gun is equipped with a replaceable unit consisting of an electronic system containing a photodetector and a microcontroller, a hermetic battery compartment, barrels fixed inside the body of the replaceable unit, wherein dowels, rods, powder charges and electric caps-igniters are placed in said barrels, a reset button for the replaceable unit, a folding ring tube, as well as an electronic system in a hermetic body-handle containing a microcontroller and a transmitter-laser, wherein the electronic system in the body-handle is connected to the electronic system of the replaceable unit via an optical channel, the hermetic body-handle is made with a safety tab, and the push-button safety device is made passing along the replaceable unit.

The underwater mounting gun is equipped with a wireless charger and an indicator screen that shows loaded and used barrels, as well as the battery level.

The technical result is an increase in the reliability and functionality of the device.

The essence of the proposed technical solution is explained by drawings, which depict:

Fig. 1 shows angles of an underwater mounting gun for driving in dowels;

Fig. 2. Section of the trunk.

Fig. 3. Section of the replaceable block.

The underwater assembly gun for driving in dowels is designed for repairing ship hulls, dams, weirs, installing special fasteners for lifting and carrying out construction and emergency rescue operations in aggressive water environments.

The underwater assembly gun consists of a sealed body-handle (1) (see Fig. 1), which is equipped with a safety tab (2), a trigger button (3), a button for resetting the replaceable block (4), a folding ring tube (5) for convenient carrying and holding of the assembly gun with two hands, and a replaceable block (6), consisting of barrels (7) (see Fig. 2), fixed inside the body of the block, a sealed battery compartment (8) (see Fig. 3), a pressure safety catch (9), which is a spring-loaded rod running along the block (6) and preventing a shot from being fired without pressing the underwater assembly gun tightly to the fixed object.

The replaceable block (6) contains several barrels (7), in which dowels (10) are placed, equipped with powder charges with electric caps-igniters (11). From the muzzle side, each barrel is protected by a membrane (12), preventing clogging of its channel.

On one of the edges of the sealed block (6) there is an indication screen (13), showing loaded and used barrels (7), as well as an indication of the battery charge level.

The use of the underwater assembly gun begins with the selection of the replaceable block (6), with the purpose of its subsequent attachment to the hermetic body-handle (1). For this, the replaceable block (6) is inserted along the guides of the hermetic body-handle (1), where it is fixed in the final position. To fire, it is necessary to activate the pressure safety catch (9), by pressing the underwater assembly gun tightly to the fixed object, clamp the safety tab (2) and press the trigger button (3). The firing of the barrels (7) occurs alternately, when the trigger button (3) is activated, the microcontroller located in the hermetic body-handle (1) generates a signal of the desired barrel and sends it to the laser transmitter, which generates pulses in the optical spectrum. In the replaceable block (6), the photoreceiver (15) receives impulses and, with the help of the microcontroller (14), decodes and sends an impulse to the required electric cap-igniter (11), and a shot occurs. Then the powder gases push the movable rod (16), the rod (16) drives the dowel (10) into the obstacle and in the extreme position the rod (16) is blocked, locking the gases, which ensures the absence of a water hammer during a shot.

If it is necessary to remove the replaceable block (6), it is unlocked and disconnected from the sealed housing-handle (1), for example, by pressing the replaceable block reset button (4).

If the underwater mounting gun needs to be charged, a wireless charger is used.

Thus, the invention made it possible to obtain a technical result by adding an optical initiation system to the device, which ensures the tightness and reliability of the device. The reliability of the underwater assembly gun is also increased by a wireless charger, which makes the body non-detachable and tight, and the functionality is also increased by the multi-barrel, which ensures high speed of installation of assembly points.
