Known water-lifting device hydraulic RAM (Vasiliev B.A., Grecov N.A. Hydraulic machines. - M.: Agropromizdat, 1988, s-177), contains a source of water supply line, an air cap, pressure pipe, pressure tank and using the system water-air to support the process of water lift.

Also known invention (RU, patent, 2117093 C1, 6 EV 13/02, 1998 - the authors used as a prototype), containing the lower reservoir with the inlet and outlet nozzles, pressure tank, switch closures and septum-separator pounds.

A disadvantage of the known device is that the entire transit flows through switching device is a magnetic switch. Magnetic switch complex to manufacture. In the case of magnetic switches when installing steel conduits with a diameter of more than 152 mm, significant energy losses due to friction during rotation of the valve, which reduces the stability of the structure. This fact excludes the applicability of the design for watercourses with high costs, which is a significant drawback.

Also the disadvantages of construction is a significant amount of mechanical elements in the circuit, the transmitting hydraulic energy differential to the piston vodopada the nick. The very existence of the piston in the pressure system is also a disadvantage of this design, as it determines the presence of friction losses.

Technical solution to the problem is the expansion of technological capabilities by reducing energy losses to friction and simplifying the process of lifting the liquid.

The task is achieved by the fact that aeroservices the water lift, containing the lower reservoir with the inlet and outlet nozzles, pressure tank, switch closures and septum-separator pounds, according to the invention additionally has the upper reservoir duct and conduit with a check valve provided with a pressure tank, bottom tank equipped with a float and valves with stems, while the switch closures are made in the form mounted on the support cylindrical sealed housing, in which is adjustably moving the spherical element, and bearing in the upper part has a latch closures provided with rods paddles bottom of the tank, with stops for contact with the levers provided with switch closures.

The novelty of the claimed proposal lies in the fact that as a result of using the design aeroservices water lift new set of structural characteristics is creating pressure for recovery is as fluid with the use of air-hydraulic pressure systems.

According to the patent and scientific literature is not found similar technical proposal that allows to judge about the level of invention proposals.

The invention is illustrated by drawings, where figure 1 shows the design aeroservices water lift (the stage of filling the bottom of the tank with air and the upper reservoir water); figure 2 shows the position of the structural elements of water lift at the initial stage of filling the bottom of the tank with the water stage in the beginning of the displacement of air from the lower to the upper reservoir and started the water in the pressure tank; figure 3 shows the position of the structural elements of water lift to the stage of completion of the filling of the lower water tank; figure 4 reflects the position of structural elements of water lift at the stage of discharge of water and air filling the bottom of the tank, lowering and filling the upper reservoir.

Aeroservices the water lift consists of the bottom of the tank 1 with an inlet 2 and outlet 3 nozzles, pressure tank 4, the switch valves 5 (which is made in the form of a cylindrical sealed casing, a partition separator 6 pounds (figure 1). The design additionally provides an upper reservoir 7 with the duct 8 and conduit 9, is equipped with a check valve 10. The lower reservoir sleep the wives of the float 11, shutter downstream 12 and the shutter of the headrace channel 13. The shutter downstream 12 is controlled through the bolt shaft downstream 14. The shutter of the headrace channel 13 is controlled through the bolt shaft of the upstream 15. The rods 14, 15 are as light as possible out of the plastic materials. On the housing bottom of the tank 1 is provided by a support 16, which consists of two parallel metal rods (not shown), between which strengthened the switch paddles 5 located therein adjustably moving the spherical element 17 (switching element) and the lock gates 18. Rods shutter downstream 14 and the shutter of the headrace channel 15 provided with lugs 19 which are in contact with the levers 20 of switch closures 5. The bolt shaft downstream 14 is moved vertically within the guide 21, and the bolt shaft of the upstream 15 moves vertically within the guide 22. The gates of the bottom 12 and downstream of the upstream 13 are composed of the same structural elements: a supporting portion of the bolt 23, the corrugated portion of the bolt 24 (fall, forming a cylinder, runs from the hydraulic fabric), the lower ring 25 of the valves 12, 13 (attached to the stem in the center of the circle on several radially arranged rods (not shown); the plane of the ring in the bolt is completely permeable to exclude hydrostatica the who and hydrodynamic effects and to increase the shutter speed). The guides 21, 22 rods of the valves 14, 15 are rigidly connected by fasteners 26 with the housing bottom of the tank 1 and the partition separator 6 pounds. The float 11 in the housing bottom of the tank 1 has a piston rod 27, provided with upper retainer 28, the lower retainer 29 and the thrust pad 30. The stem 27 of the float 11 moves vertically up and down through the guide 31 of the rod 27, provided with a corrugated sealing membrane 32, eliminating air loss from the bottom of the tank 1. Resistant pad 30 has a flexible coupling 33 to the switch control gates 5. Bearing 16 has a hinge 34 for mounting of switch closures 5 and the hinge 35 for fastening the lock gates 18. The latch gate 18 includes a housing holding a ball-shaped element 36 and is equipped with the holding arms 37 that are connected via hinges 38 with the rod gates of the bottom 14 and downstream of the upstream 15. The housing bottom of the tank 1 equipped with an air valve 39, which is spring loaded in the closed position. The upper tank 7 due to the restraint of the float 40 and the retainer 41 operates on the level of the water surface of the upstream. Watanapongse valve 42 located at the bottom of the upper reservoir 7, provides a fill cycle of the upper water tank 7 and the check valve duct 43, located at the entrance of the duct 8 into the upper tank 7, excl which includes water penetration into the duct 8.

Aeroservices the water lift works as follows. When draining water from the bottom of the tank 1 it enters the air (figure 1). The air flows from the upper reservoir 7 when lowering and filling it with water through watanapongse valve 42. The float 11 is lowered when draining water along the rod 27, and, reaching the bottom of the latch 29, he pulls his weight down rod 27, which is connected with a flexible coupling 33 with the arm 20 of the switch valves 5, with the hinge 34, the switch gate 5 is rotated and reaches the middle position II position III (Fig 1). Position III is a position of unstable equilibrium, and further lowering the left arm 20 of the switch valves 5 leads to rolling adjustably moving spherical (switching) element 17, which is its weight turns the switch gates 5 in position I. at the same time the right arm 20 of the switch valves 5 bearing on the stop 19 and raises the bolt shaft of the upstream 15, it goes lower ring 25 and is compressed corrugated portion 24 of the shutter of the headrace channel 13 and open access water from the upper pool in the bottom of the tank 1. When lifting the bolt shaft of the headrace channel 15 through a hinge 38 and right restraining lever 37 rotates on the hinge 35 of the lock gates 18. When turning the body of the lock gates 18 left Phi is serouse lever 37, acting via the hinge 38, lowers the bolt shaft downstream 14, when it is lowered the lower ring 25 and stretched corrugated portion 24 of the shutter downstream 12 and stops draining water from the bottom of the tank 1 into the lower reach. In the case of lock gates 18 is rolling spherical retaining element 36, the valve downstream 12 is fixed in the closed position, the shutter of the headrace channel 13 is fixed in the open position and begins filling the bottom of the tank 1 water from the upper reach (figure 2). Filling occurs due to the energy difference between the level of the upstream and the water level in the lower tank 1. Hydraulic differential is provided by a partition separator pounds 6 role of the retaining structures. At the initial stage of filling water to the bottom of the tank 1, the upper tank 7 is in the lower position and maximally filled with water (figure 2). The upper tank 7 through a fortified it latch 41 is based on holding the float 40. The air from the bottom of the tank 1 while it is being filled with water is expelled through the duct 8 into the upper tank 7. Thus, in the upper reservoir 7 creates a pressure, which closes watanapongse valve 42 and the water from the upper reservoir 7 raises the check valve water the ode 10 and the conduit 9 is displaced in the pressure tank 4. The process of water lift, in which the upper tank 7 as the ousting of water filled with air and floats up due to the action of the buoyancy force (figure 3). Filling the bottom of the tank 1 with water leads to the rise of the float 11 along the rod 27 to the upper clamp of the float 28. Reaching the latch 28 of the float 11, following the water level in the lower tank 1, raises the rod 27 and the thrust pad 30. Resistant pad 30, lifting, turning the switch gate 5 from the position I to the position of unstable equilibrium III (figure 3). The passage selector valves 5 position III adjustably moving spherical (switching) element 17 rolls to the right and puts his weight switch gates 5 in position II. When this occurs the change of position of the lock gates 18, the shutter downstream 12 is fixed in the open position, the shutter of the headrace channel 13 is fixed in the closed position, starts draining the water from the bottom of the tank 1 and the flow of air (figure 4). The upper tank 7 under the action of its own weight falls, watanapongse valve 42 is open and overlooks the water, which displaces the air in the duct 8 at the bottom of the tank 1. Check valve duct 43 stops the movement of air at the completion of filling of the upper reservoir 7 water and eliminates the prob is the possibility of operation of the duct 8 "siphon". When draining water from the bottom of the tank 1, in the case when the non-return valve of the duct 43 is closed, the air in the lower tank 1 is supplied through the air valve 39. The air valve 39 is spring-loaded in the closed position and opens when there is a slight vacuum at the bottom of the tank 1. Subsequent draining of water from the bottom of the tank results in a system of structural elements of the water lift in the state shown in figure 1, from which the system switches to filling the bottom of the tank 1, that is, begins the next cycle of water lift.

Aeroservices the water lift, containing the lower reservoir with the inlet and outlet nozzles, pressure tank, switch closures and septum-separator pounds, characterized in that it additionally has the upper reservoir duct and conduit with a check valve provided with a pressure tank, bottom tank equipped with a float and valves with stems, while the switch closures are made in the form mounted on the support cylindrical sealed housing, in which is adjustably moving the spherical element, and bearing in the upper part has a latch closures provided with rods paddles bottom of the tank, with stops for contact with the levers, which is provided with switch closures.
