The hydraulic system of emergency protection multisupport sprinkler includes a water conveyance pipe 1 is placed on a support 2 with the hydraulic actuators 3, each of which is made by valve distributor 4 and the switching mechanism 5 with a thrust of 6 placed in the hub 7 of the power lever 8. The hydraulic system is equipped with a hydraulically operated limit switch 9, is made in the form of a housing 10 of the membrane actuator 11 and the hollow shaft 12, the end thrust 6 switching mechanism 5 connected to the housing 10 of the membrane actuator 11 and is located inside the hollow rod 12 that is installed with the possibility of interaction with the sleeve 7 power lever 8, and the diaphragm actuator 11 is hydraulically connected to the tube control 13 connecting sequentially actuating valves 14 protection system, hydraulically operated limit switch 9 is supplied with power by a spring 15, which interacts with the upper part and the lower part of the body of the membrane actuator 11, and the inner surface of the housing 10 notmember membrane actuator 11, hydraulically connecting it with the pipe control 13 protection, the valve distributor 4 last (leading) support 2 is equipped with a hydraulic timer 17, made in the form of a storage tank 18 with adjustable orifice 19, which is connected through a tee 20 line drain line 21 of the hydraulic actuator 3 and the float 22, rigidly connected with the rod 23, is placed in the guides of the tee 20 drain line 21 of the hydraulic actuator 3, and the upper end of the rod 23 provided with a stop 24, which interacts with additional actuating valve 25 associated with the system of protection and mounted on quadratorum casing 26, and interacting with his rod 27 with the Cam 28, located on spring loaded pendulum 29, rigidly mounted on the axis 30, is placed in the housing body 26, and the rod 27, the Executive of the valve 25 equipped with a hollow part 31, limited in movement by the surface of Cam 28 and the casing 26, and the stop 24 is made of two parts, pivotally connected with each other, while the second link 32 is moved on the bottom shelf quadratierung casing 26 and provided with a slot 33 located therein pendulum 29.

The hydraulic system of emergency protection multisupport sprinkler works following proishodit filling tube control 13 security that provides water flowing through the grooves 16, made in the body of the housing 10 in the membrane actuator 11. As a result, namebrand cavity hydraulically operated limiter 9 is pressurized, providing the compression force of the spring 15 and the movement of the hollow rod 12 in the lower position, providing communication with the sleeve 7 power lever 8, which allows the operation of the switching mechanism 5 and the valve of the distributor 4, and the movement of the hydraulic actuator 3. This facilitates movement of the machine.

Flow-through grooves 16 provide a continuous passage of water in the membrane actuator (and from there into the opening of the Executive of the valve when the emergency situation) in the points of location of the hollow rod 12 in the upper position. This ensures that the speed alarm system protection and reliability of its work.

When the emergency situation at the intermediate supports 2 is invalid bending pipe machine 1 and the opening of the Executive of the valve 14 is defective truck that causes a drop in pressure in the control tube 13 and the membrane actuator 11. Under the influence of the force of the spring 15 is rapid movement of the hollow rod 12 in the upper position, financial p is 4. The hydraulic drive 3 the last support stops, causing the stop of the whole machine. The pressure drop in the control tube 13 causes the closing of hydrosulfite for the time at which hydraulic shock in the pressure (inlet) pipe does not occur. Rapid movement of the hollow rod 12 in the upper position due to the force of the spring 15, when the opening of the Executive of the valve 14 enables reducing the stop time of the last (leading) trucks, which prevents damage to machine failure hydrosulfite and reduces the curves of the water conveyance pipeline 1 machine in case of emergency situations of intermediate trolleys.

When the emergency situation in the past (leading) leg is stop the whole machine, but due to the lack of bend water conveyance pipeline machine 1, since the intermediate trolleys are in working position, the opening of the dampers 14 does not occur, and therefore the machine from the mains supply is not turned off.

In this case, the work enters the hydraulic timer, which is as follows.

When working working last (leading) truck, at each cycle of the hydraulic drive 3 (lowering it down) drain the water from it through to into the atmosphere with the distribution in the form of rain on the field. The incoming flow into a storage tank 18 provides filling of the tank 18 and the rise of the float 22 in the extreme position.

Causing the stop 24 mounted on the end of the rod 23 moving in the guides of the tee 20, occupies the upper extreme position, excluding the interaction additional Executive valve 25.

From the storage tank 18 through an adjustable orifice 19 is a constant outflow of water in the atmosphere given flow rate, allowing for every stroke of the hydraulic drive 3 to maintain the specified level in the tank 18. This prevents the float 22 in the position in which the stop 24 prevents the interaction of the additional actuating valve 25.

The emergency stop on the last (leading) trolley stops the flow of water from the drain line 21 in the storage tank 18.

Resulting in a constant outflow through an adjustable orifice 19 causes a drop in the level in the tank 18, which leads to the lowering of the float 22 and the rod 23 with the stop 24 down. Thus the second link 32 of the stop 24 moves forward on the bottom shelf quadratierung casing 26. Whenever the second link 32 horizontal polozheniya pendulum 29 and the influence of the Cam 28 on the shaft 27 of the valve 25, which, opening, causes a drop in pressure in the tube 13 control system protection. The pressure drop in the tube 13 provides disconnecting the machine from the mains supply.

After a fault is the last (leading) truck operator directly with it shall enable the machine to work as follows.

Is the sealing of an additional Executive of the valve 25 by lifting the second hollow element 32 on the rod 27 up installing it on the shelf copier 28.

The result is constantly the incoming ow from the pressure of the inlet pipeline provides a pressure rise in the tube 13 management protection, which leads to a pressure rise in adminpanel cavity hydraulically operated limiter 9 and the movement of the hollow rod 12 in the lower position for the impact of his shaft with bushing 7 power lever 8. With the opening of hydrosulfite and water supply in the pipeline 1 machine.

This causes movement of the last (leading) truck and the incoming water flow from the drain line 21 in a storage tank 18, which provides rise of the float 22 is in its extreme upper position.

With the rise of the float 22 moves the hinge so.

Resulting in a spring pendulum 29 is perpendicular position and is set in the middle of the slot 33 of the second link 32 of the stop 24. This enables lowering of the hollow element 31 Executive of the valve 25 on the rod 27 downward in the bottom of the copier 28.

The machine is in automatic mode under the control of the security system.

As a result of this proposed technical solution in comparison with previously known inherent high reliability, prevention of negative consequences if the accident last (leading) truck, simplicity and automation control sprinkler.
