Description

The invention relates to the field of water intake from surface sources and can be used both in the waters of marine and freshwater reservoirs open to winds, causing the formation of a “surge” wave. When taking sea water, the latter is subjected to desalination.

A device for collecting water from surface sources is known, comprising a float, a water intake chamber connected thereto, a pressure pipe, a trash holding device and a cargo anchor with a control cable [1].

The water supply in the known device from the water intake chamber to the pressure pipe is carried out using a submersible pump driven by an electric motor, and all the drive equipment is located in the housing of the device.

This complicates the design of the device itself and significantly increases the cost of its operation.

A device for collecting water from surface sources is known, comprising a float, a water reception chamber rigidly connected to it, a pressure pipe located under the water edge and connected to the water reception chamber, and a trash guard [2].

Water enters the pressure pipe from the water intake chamber through openings located on its lower generatrix, the openings being made decreasing in the direction of water movement through the pipeline.

To move water through the pipeline, it is necessary to use pumping equipment, which, like in the above analogue, complicates the design of the device itself and increases the cost of its operation.

The aim of the present invention is to simplify the design of the water intake device and reduce the cost of its operation due to the use of "surge" wave energy for pumping water into the pressure pipe.

This goal is achieved by the fact that in the known design of a device for collecting water from surface sources, containing a float, a water intake chamber rigidly connected to it, a pressure pipe located under the water edge and connected to the water intake chamber, and a trash guard, it is additionally equipped with a cargo anchor and with a cable, the water intake chamber has an opening that protects the specified grill from above, and a spring-loaded damper made with the possibility of vertical movements to overlap the specified about openings, the pressure pipe is made in the form of a main part and the connection of tubular links in the form of an inverted T, the vertical of which is rigidly connected to the water intake chamber, and the horizontal one is equipped at the ends with check valves - pressure and suction, and from the pressure valve side it is connected with a flexible hose with the main part of the pressure pipe, and from the side of the suction valve - is equipped with a brush trash holder.

The implementation of the water intake chamber with a spring-loaded flap, with the possibility of vertical movement, and the communication of the chamber with a horizontal tubular link equipped with check valves, in combination with the use of a cargo armature with a cable, providing adjustment of the height of the vertical position of the water reception chamber, allows you to provide the necessary pressure in the pressure pipe for pumping withdrawn water. At the same time, there is no need to use specialized equipment (pump, engine, etc.). The device itself works as a kind of pump. Under the action of a “surge” wave covering the water intake chamber, its spring-loaded damper moves downward, exerting pressure on the volume of water in the chamber. Under the action of the pressure generated, the horizontal pipe-link check valve opens in the pressure mode, and the valve operating in the suction mode closes. As a result, water from the water intake chamber through the connection of the tubular links in the form of an inverted T and a check valve enters the main of the pressure pipe. When the “surge” wave leaves the water intake chamber, the spring-loaded damper returns to its original position, the pressure in the pipeline system drops, the valve operating in the pressure mode shuts off, and the one operating in the suction mode opens. Water entering through it fills the cavity of the horizontal tubular unit, creating the necessary backwater.

As already mentioned above, such an embodiment of the device, which is essentially a kind of pump using the "surge" wave energy, does not require the use of specialized equipment, which simplifies the design of the device and significantly reduces the cost of its operation.

The invention is illustrated in the drawing, which shows a General view of the claimed device.

A device for taking water from surface sources includes a water intake chamber 1 mounted on an annular float 2. The water intake chamber is equipped with a spring-loaded damper 3, which has the ability to move vertically. The hole in the water intake chamber blocked by the shutter is protected by a trash guard 4. The ends of the spring 5 are oriented from the top by the sleeve 6, and from the bottom by the upper end of the vertical link 7, which is one of the elements of the connection of the tubular links in the form of an inverted T and placed in glasses 8 and 9.

The vertical link is rigidly connected to the horizontal tubular link 10, equipped at both ends with check valves 11 and 12, the first of which works in pressure mode, and the second in suction mode. On the side of the pressure valve, the horizontal tubular link through the insert 13 and the flexible hose 14 is connected to the main part 15 of the pressure pipe, through which water enters the tank 16 on the shore of the reservoir. On the side of the valve operating in the suction mode, the horizontal tubular link is equipped with a nozzle 17 with a brush trash holding device 18.

The device is equipped with a cargo anchor 19, with the help of which, by tensioning the cable 20, the height of the vertical position of the water intake chamber in the open reservoir is adjusted when the natural level of the water in the reservoir changes.

A device for taking water from surface sources can be used both in the water areas of marine and freshwater reservoirs. When taking sea water, the latter is subjected to desalination.

The device is installed from the side of the prevailing winds in a given area of the water area, causing a “surge” wave. Using the cargo anchor 19 and the cable 20 set the water intake chamber 1 in a floating position. When the “surge” wave covers the intake chamber, its spring-loaded damper 3 moves downward, compressing the spring 5 and exerting pressure on the volume of water in the chamber.

Under the action of water pressure, the non-return valve 11 operating in the pressure mode opens and the non-return valve 12 operating in the suction mode is closed. Water from the water intake chamber 1 through the vertical 7 and horizontal 10 links of the tubular connection in the form of an inverted T enters the flexible hose 14 and then into the main part 15 of the pressure pipe and the shore tank 16.

When the “surge” wave rolls back, the intake chamber 1 floats to the water surface and its shutter 3, without experiencing pressure from above, moves upward by the action of the spring 5, draining part of the water from the chamber into the reservoir. In this case, the check valve 11 is closed, and the valve 12 opens, giving water access to the horizontal tubular link 10 through the nozzle 17 with the trash holding device 18. Thus, the necessary water pressure is created in the horizontal tubular link 10 for the subsequent pumping cycle, when the “surge” wave will again cover the water intake chamber.

When the natural level of the water in the reservoir changes (tide, ebb, shallowing, etc.), the height of the water intake chamber is regulated by a cable 20 using a cargo anchor 19.

Creating a periodically repeating pressure in the "water intake chamber - pressure pipe" system using a spring-loaded spring-loaded damper using "surge wave" energy, this device does not require the use of specialized equipment (a pump with a drive), which simplifies the design of the device itself and significantly reduces the cost of its operation.
