The invention relates primarily to the field of Oceanography and designed for the intake of deep-water seas and oceans from selected horizons for subsequent physical, chemical, biological investigations or to extract from it certain mineral or gas components for industrial purposes. It can be used to solve any other problems, the technological step of which is the rise of water from a given depth of open water.

Usually the ascent of deep water to the surface, for example, srsly water, by using a submersible electric pump which is fixed on the end of the diversion pipe and drop in depth with the winch. For example, known means for lifting sea water used in the device for degassing water [1]. It contains submersible water pump for borehole type with the water hose in the form of a plastic tube through which water is forced upward. Similar symptoms with the essential features of the claimed invention are pump attached to a water hose.

The disadvantage of these analogues is that such equipment is quite cumbersome, difficult, especially unsafe in stormy sea conditions and consumes significant amounts of electricity is used in such a W�demneh the pumps zapityvaya cable voltage 220-380 In and consume power on the order of several kW.

Famous wave water lift [2], intended primarily for application in agriculture. It uses the energy of wind waves in the open water by directly converting it to water-lifting force vertical to the wave displacement and hydrodynamic pressure wave. The water lift includes a fixed support mounted on the bottom of an open reservoir, is provided in its upper and lower parts of the rotary Assembly with the actuator is rigidly fixed to the horizontal movement of the frame with a piston pump and lever supports, in the lower part of the bearing is provided with a lever with the possibility of free vertical movement rigidly connected with the rod of the pump and the float rod mounted at an angle of 105° to the axis of the lever. Lists the device as claimed solution is a wave machine most closely fits the present invention, a set of attributes. Therefore, it is selected as a prototype. Similar features of these technical solutions are the presence of a floating element and the pump, and also the fact that the claimed device and the prototype can be attached to the open bottom of the reservoir.

The disadvantages of the prototype are its complexity and limitation of application, since it is designed to work in open water shallow - mouth�eusto attached to its bottom. In order Oceanographic research this device can be used only in a narrow coastal zone and is not applicable for the lifting of deep-sea water to extract hydrogen sulfide for industrial purposes.

The basis of the invention tasked with creating a device to lift water from a reservoir that converts the energy of surface waves in this reservoir water-lifting force, and in which the totality of characterizing its essential features provides the technical result - the simplification of the device. Thus at the expense of features that characterize the production of the device is achieved a new property: the ability of abstraction it is with deep open waters of seas and oceans, resulting in another technical result of the invention is the extension of the scope of the device for lifting water.

The problem is solved in that the device for lifting deep sea water to the surface by using mechanical energy of surface waves of the sea, which contains the float element, the pump and rigidly attached to the seabed, what is new is that the pump is made in the form of a cylindrical tubular vertical half-submerged in the sea of the camera, which is rigidly attached to the seabed or to a massive buoyancy and supplied in Saint�their lower and upper parts respectively of the lower and upper fittings, the first of which is fixed located in the water hose of a certain length, wherein the camera is placed is fixed to the piston rod in the form of an inlet check valve, which is made with the possibility of transmission of water in the chamber only in the direction from the bottom fitting to the top and is connected by a rod with a float item that is placed on the surface of the sea. The piston may be made in the composition of the membrane adjacent to the plane of the disk, formed with through holes with axes parallel to the axis of the disk. Optionally, instead of the disk can be applied to the cylinder.

The differences of the claimed invention to the design of the wave pump, relations characterizing its characteristics with other essential features of the device, as well as to the peculiarities of the formulation of the device, namely, it can be firmly attached to the shelf zone to the sea floor by means of support, as a prototype, and yet it can be through the mount rigidly attached to a massive buoyancy, for example the hull of a vessel or marine buoy, because the difference of inserzionisti massive buoyancy and light. buoyancy - floating element - determines the efficiency of the design with this new fastening-lifting device.

Summary of the invention explains�I use the illustration, which depicts the setting of the device by fixing it on a massive buoyancy.

The device comprises a pump wave in the form of a cylindrical tubular vertical half-submerged in the sea of camera 1, which may be formed from a cut aluminum tube with a length of 1500 mm, an inner diameter of 100 mm and a wall thickness of 6 mm. muted Trumpet top cap in the center of which is mounted the seal 2 and the lower plate installed W bottom fitting 3, on which are fixed the suction pipe 4 of a given length with the end 5, which serves for the penetration of the hose, the vertical location in the water column and prevent the hose of a foreign body. As the hose 4 can be used a polyethylene tube with an inner diameter of 32 mm, a length of 1000 m. the End 5 is provided with metal mesh surface. In the upper part of the chamber 1 contains the upper fitting 6 raised to drain water, for example in the reactor 7, which produces further manufacturing operations to extract the required components of the water or its use. Camera 1 through the mount rigidly attached to a massive buoyancy - sea buoy 8. The device comprises a U-shaped rod 9, is made of bent stainless steel rods with diameters of 6 mm. At one end of the rod 9 is rigidly behind�replen float element 10, placed on the surface of the sea, and which is made of vinyl plastic in the form of a disc diameter 500 mm, height 150 mm. the Other end of the U-shaped rod 9 through the gland 2 is passed into the cavity of the camera 1 and is rigidly secured to the piston, D. g I stroke of which the inner surface of the camera processed. The piston is made in the form of an inlet check valve that passes water in the chamber only from below upwards, for example it is made in the form of a disk 11, for example made of PTFE, with a height of 8 mm with through holes whose axes are parallel to the axis of the disc, and adjacent to the upper plane of the membrane 12, which is formed, for example, kislotostojky rubber thickness of 4 mm and a diameter corresponding to the diameter of the disc 11. To protect the device from impacts with the appearance of surface waves of large height, such as above 1 m, the camera is provided with a top 13 and bottom 14 of the stroke limiting rod 9, which, for example, made in the form of rubber cushions.

Thus, the float element and the piston of the pump form a structurally unified whole.

The device operates as follows. Under the influence of wave energy of the float element 10 performs a vertical oscillatory motion. Summary of the invention in that such fluctuations of the float is converted to translational motion of water from the depths of the sea to the top. Namely, when under�EME waves of the float element 10 goes up and at the same time rises the piston pump, while its body - camera 1 - remains stationary due to the inertia of the sea buoy 8, which has a mass of, for example, 1000 kg of Water in newportnews space of the chamber 1 presses the membrane 12 to the upper plane of the disc 11 and covers his hole. In subpiston chamber 1 in a vacuum and the water depth along the hose 4 rises up, filling this space. When lowering the wave of the float element 10 moves downward and at the same time the piston descends. This disturbed a tight seal of the membrane 12 to the disk 11, the holes are opened and the piston travels down through the water subpiston chamber. When moving the float up again the hole ROM 11 overlapped by the membrane 12, clipping nagorskiy volume of water. The piston goes up, pushing the deep water from the chamber 1 through the drain fitting 6 into the reactor 7.

In operation of the device in conditions of intense excitement it can be equipped with additional non-return valves, which may be located on the lower nipple 3, the end 5 and the hose 4, for example every 50 m of its length.

The advantage of the proposed device is that it requires no power supply and operator intervention is safe and effective due to its ability to deliver with great depth on top of�awn significant amount of water due to the continuity, because the wave vibrations of the surface, including wind waves, almost always take place in open pond <5 especially in the seas and oceans, where it mainly operates the device.
