Description

Известны импульсные водометы, включаюшие ствол с насадкой, т желый поршень, поршень-боек и привод дл взвода т желого поршн . В таких водометах шток т желого поршн в конце разгона входит в ствол и соудар етс с поршнем- бойком, что ведет к интенсивному разрушению как штока т - желого поршн , так и поршн -бойка.Pulse water cannons are known, including a barrel with a nozzle, a heavy piston, a piston head and a drive for cocking a heavy piston. In such water jets, the heavy piston rod at the end of the acceleration enters the barrel and collides with the piston head, which leads to intensive destruction of both the piston rod and the piston block.

Дл увеличени надежности и долговечности предлагаетс водомет, у которого шток т желого поршн шарнирно соединен с поршнем-бойком, а ствол - с амортизатором , раздел ющим его на две части.In order to increase reliability and durability, a water jet is offered, in which the heavy piston rod is pivotally connected to the bushing piston and the barrel with a shock absorber dividing it into two parts.

На чертеже схематично изображен опи- сываемый водомет в разрезе.The drawing schematically depicts a water jet in section.

Ствольна часть 1 водомета разделена на два участка окном 2, соединенным с амортизатором, который выполнен в виде цилиндра 3 с поршнем 4, отдел ющим упругую полость 5 от ствола водомета.The barrel part 1 of the jet engine is divided into two sections by a window 2 connected to a shock absorber, which is designed in the form of a cylinder 3 with a piston 4 separating the elastic cavity 5 from the jet engine barrel.

Амортизатор служит дл приема выбрасываемой через окно 2 воды при разгоне т желого поршн 6. Шток 7 т желого поршн соединен шарнирно с порш The shock absorber serves to receive water ejected through the window 2 when the heavy piston is being accelerated 6. The 7 heavy piston rod is hingedly connected to the piston

нем-бойком 8, наход щимс в стволе водомета .German 8, located in the jet's trunk.

Отвальна часть заполн етс водой от насоса 9 через полость и окно в стволе. Вод ной насос имеет предохранительный клапан 1О. Обратный клапан 11 преп тствует попаданию в насос воды из ствола водомета при разгоне т желого поршн .The waste part is filled with water from the pump 9 through the cavity and the window in the barrel. The water pump has a safety valve 1O. The check valve 11 prevents water from the water jet barrel from entering the pump during acceleration of a heavy piston.

Выходное отверстие насадки 12 во врем заполнени ствола водой закрыто заслонкой 13. Открывание и закрывание заслонки производитс автоматически с помощью гидравлического выключател 14 Разгон т желого поршн происходит в пневмоцилинцре 15. Штокова полость пневмо- цилиндра соединена с атмосферой окном 16, запоршнева с ресивиром 17 окна ми 18,The outlet of the nozzle 12 during the filling of the barrel with water is closed by the flap 13. The flap opens and closes automatically by means of a hydraulic switch. 18,

Claims

The extreme piston is forced to the extreme position by means of a hydraulic actuator 19, the rod 20 of which is connected by means of an coupling device 21 with a heavy piston. mefib when moving its stock in the jet's barrel. The connection of the rod 7 with the piston 6-box 8 excludes the impact of these parts. The work of the water cannon is as follows. In the receiver 17 and the pneumatic cylinder pneumatic cavity, gas is injected from the compressor to a pressure equal to the calculated one; gas is supplied to the elastic cavity 5 of the shock absorber at a slight pressure. Under the action of the gas, the pistons 4 and 6 are moved to the extreme position. The piston blocker closes the windows 2 in the barrel 1. After the water jet is charged with gas, the pump 9 is turned on, supplying water under pressure somewhat lower than the pressure in the elastic cavity of the shock absorber. Since window 2 is blocked, getting into the vehicle in the barrel is excluded. The automatic firing of the water jet starts after the hydraulic actuator 19 is put into operation. With the start of movement of the hydraulic piston and hydraulic actuator, the hydraulic limit switch 14 is activated in the direction of the heavy piston, and the damper 13 closes the nozzle opening. Hydraulically, the heavy piston is inserted into the extreme position, and through the opening 2 of the window, the barrel is filled with water. When the heavy piston approaches the rearmost position, the flap 13 automatically opens the nozzle opening. From the extreme rear position, the heavy piston, under the action of gas, begins to accelerate along with the piston 1 and the water, which is then forced out through the window 2 into the shock absorber and partially through the nozzle. The shock absorber piston rises and the pressure in the elastic cavity rises. By the time the window 2 is completely blocked by the piston-boy, the heavy piston acquires the kinetic energy necessary to release water through the nozzle. After the shot, the cycle is repeated. Claims of the invention A pulse water jet comprising a barrel with a nozzle, a heavy piston, a firing piston, a receiver connected to a dead piston cavity, and a drive for a heavy piston, characterized in that in order to increase reliability and durability, the heavy piston rod is harnessed it is connected with the piston brisk, and the barrel with a shock absorber dividing it into two parts.
