Description

The invention relates to the field of water intake from an intermediate layer of open sources, in particular from reservoirs, sedimentation tanks, catchments, and open winds, and with a wide range of level fluctuations.

The effectiveness of using water bodies for water intake depends on the depth of intake from it to the consumer, and this is also due to the fact that the water stratification in it occurs according to temperature gradients and the separation of pollution into components with different densities. Water intake from the surface of reservoirs, sedimentation tanks allows water to be taken in predetermined volumes, but for this purpose these waters must be cleaned of impurities with a density lower than the density of water (oil products, floating objects, ice and other suspended particles), and when taking water at the bottom of a reservoir underwater currents are formed, which carry settled sludge to the water intake.

Analysis of existing methods and means for water intake from sources indicates the need to develop devices for environmentally friendly water intake to the consumer, which can be solved by taking water from the intermediate layer at the depth of the reservoir or sump that meets environmental safety requirements.

The head of the river water intake is known, consisting of a pipeline and an intake tip, the pipe is made of articulated pipe segments, and the head is equipped with a float located above the suction hole and a hemispherical protective net (Copyright certificate SU No. 108060, ЕВВ 8/04 of 09/14/1956) .

It is also known a device for sampling the surface layer of liquid, containing a movable pipe with a receiving hole, pivotally connected to the receiving pipe of the pump and equipped with a float, while the movable pipe is made up of pivotally connected bends and a straight section equipped with a saddle that contacts the seating surface of the movable along the straight section of the fence, made in the form of a hemispherical cup with bent edges (Copyright certificate SU№393420, Е03В 1/00 of 08/10/1973).

The disadvantages of the known devices are the complexity of the design and its operation, material consumption and unreliability of the devices. In addition, there is insecurity from the depression funnel, capturing the surface layers of the water of the reservoir or sedimentation tank, the lack of reliable regulation for water intake.

A device for collecting water from surface sources is known, comprising a float rigidly connected to the float and a water receiving chamber in the form of a tray installed underneath it, a water intake pipe located below the water edge, the upper part of which is connected to the float, and the lower part is installed with a clearance of water-receiving chamber and is made with holes decreasing in the direction of movement of water in the pipeline (Copyright certificate SU No. 1622535, Е03В 3/04 of 01/23/1991).

However, 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. And for the movement of water through the pipeline, the use of pumping equipment is necessary, which complicates the design of the device itself and increases the cost of its operation. In addition, the disadvantage is the insecurity from the depression funnel, capturing the surface layer of water of the reservoir or sedimentation tank, the lack of a smooth drive to regulate water intake.

Known floating water receptacle containing a deck with an area larger than the area of funnel formation at the inlet, a water reception chamber with a bottom shutter and radially arranged rigid communication elements and a suction bell located vertically in the center of gravity of the deck, the entrance of which is flush with the bottom of the deck (Copyright certificate SU No. 1155692 , Е03В 3/04 dated 05/15/1985).

The disadvantage is the tight connection of the water intake with the suction pipe, makes the structure heavier and reduces maneuverability when moving to a new place. In addition, the elongated shape of the water intake in the cramped conditions of water intake makes it difficult to place it, and it is not associated with a wide range of fluctuations in the levels and possibilities of water bodies open to winds, and it is also difficult to extract it. In addition, during operation of the water intake, there is no automatic filling of the chamber with water, which makes it inconvenient to operate. The selection of a layer of clarified water from the middle layers is difficult for normal operation of the pumps and should be a certain filling depending on their performance. The cost-effectiveness of water intake can be improved by using the proposed device from the middle layers of clarified water from reservoirs. This will dramatically ensure the intake of water free of suspended abrasive particles, that is, the standard resource of the pump is fully used.

The closest technical solution adopted for the prototype is a device for water intake 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 grille from above, and a spring-loaded shutter, made with the possibility of vertical movements, to overlap of the indicated hole, the pressure pipe is made in the form of the main part and the connection of the tubular links in the form of an inverted T, the vertical of which is rigidly connected to the water intake chamber, and the horizontal is equipped at the ends with check valves - pressure and suction, and from the pressure valve side it is connected by a flexible hose to the main part of the pressure pipe, and on the suction valve side is equipped with a brush trash holding device (Patent RU No. 2289000, EV 03/10 of 10.12. 2006).

The disadvantage of this device is the possibility of sticking floating debris on top of the grate and blocking the opening of the intake chamber, made with the possibility of vertical movements on the surface of the water. In addition, water intake at the surface can cause the capture of oil stains and substances with a density lower than the density of water, they are sucked from the surface of the water layer of the reservoir, the absence of a smooth drive to regulate water intake from the intermediate depth layers. In addition, the complexity of the design and its operation, material consumption and unreliability in the operation of the spring.

The objective of the invention is to increase the efficiency of the device for water intake by increasing its maneuverability and ease of use, i.e. an improvement for water intake from an intermediate layer of water sources at all positions of a movable flexible non-crushable pipe connected to a nozzle having a mushroom shape with any flow rates in water bodies.

The technical result from the use of the invention lies in the possibility of increasing the possibility of water intake and ensuring capture of the purest water from sources by fixing the nozzle, which has a mushroom shape, to the guide riser with an adjustable float along its height, as well as by fixing to the bottom of the nozzle with a nozzle mounted counterbalance cargo and water intake of any water layers, reduction of water intake time in the middle layers of water bodies with different water flow rates.

The technical result is achieved by the fact that the device for water intake from the intermediate layer of sources, containing a float, a water intake chamber, a pressure pipe located under the water edge, a cable, a water intake chamber has a hole, a flexible hose is connected to the pressure pipe and the pipe link, the pressure pipe is equipped with a flexible an indelible pipe connected to a nozzle having a mushroom shape with inlets on the inside, while the nozzle is attached to a guide riser with an attached float m with the possibility of axial movement and freely installed on the guide riser between the limiters of its movement, while to balance and direct the flow into the nozzles and to position it in a horizontal position, an adjustable counterweight is mounted in the lower part.

In addition, the limiters on the guide riser are fixed at a height of adjustable immersion depth of the nozzle, which has a mushroom shape and is an autonomous floating receiver with the necessary landing on the guide riser for the intake of clean water.

In addition, the pressure pipe is attached to a vertical screen with an integrated pump, the lower part of the screen of which is connected to the cable, and the upper part is connected to the buoyancy chamber.

An autonomous floating receiver made with a nozzle having a mushroom shape, immersed to the height of the depth control of the intermediate layer of sources, automatically performs at the required water depth for operation of the water intake, which increases the maneuverability of the nozzle having a mushroom shape when attached with a flexible, non-crushable pipe with a pressure pipe, with a vertical screen with an integrated pump, and the upper part of the screen is connected to the buoyancy chamber. Thus, the new features allow the proposed technical solution to show new properties, which are used in reservoirs or sedimentation tanks, water withdrawal only from the middle layers of the sources, excluding the surface layer contaminated with oils, can increase the level of environmental safety of consumers and achieve great compactness of the device.

The above new features and properties are absent in the known technical solutions and allow the proposed technical solution to achieve the effects of simplifying the design and increasing the reliability of the device. This suggests that the proposed technical solution meets the criteria of "novelty" and "inventive step".

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

A device for withdrawing water from an intermediate layer of sources includes a buoyancy chamber 1 connected to a vertical screen 2, in the upper part of which a submersible pump 3 is mounted. A cable 4 is fixed at the bottom of the vertical screen 2. The device includes a submersible pump 3, for example, with a pressure pipe and flexible non-crushable pipe 5 with an autonomous floating receiver in the middle part of the stream, which consists of a nozzle 6 having a mushroom shape, with inlet openings 7 on the inner cavity in the form of a chamber 8, nozzle 6, openings to the right They are connected towards the nozzle 6 with a short nozzle connected to a flexible non-crushable pipe 5. For a better horizontal location of the nozzle 6 in the middle part of the flow, the device is equipped with a guide riser 9 with a float 10 in the upper part with the possibility of axial movement freely between the stops 11 and 12, riser 9 which is fixed to the nozzle nozzle 6, having a mushroom shape. The nozzles 6 in the lower part, coaxially to the riser 9, have an adjustable counterweight 13 fixed to the riser 14. The end of the riser 14 can be made, for example, in the form of a screw-nut 15 for an adjustable counterweight 13, i.e. the possibility of replacing it. The air intake is made in the form of a vertical tube 16 with a check valve 17 and is connected to the chamber 8 of the nozzle 6, which is connected to the atmosphere and the upper end of the tube 16 is located above the water level in the source. The depth of water intake is regulated by moving the float 10, fixed with the possibility of axial movement between the stops 11 and 12, relative to the immersion of the nozzle 6 in the middle layers of the source, this in turn does not allow the development of a depression funnel and to suck in the surface layers of water in which the pollution accumulates. In addition, the nozzle 6 is balanced by both the float 10 and the counterweight 13. Thus, the height of the horizontal position of the nozzle 6, which is connected by means of a short pipe with a flexible non-crushable pipe 5 in an open reservoir, is regulated.

A device for taking water from an intermediate layer of sources works as follows.

The float 10 together with the counterweight 13, while holding the nozzle 6 connected to the flexible indelible pipe 5, in the immersed state, provides a constant pressure head at the inlet with the inlet openings 7 of the chamber 8 of the nozzle 6. In this case, water from the intermediate layers enters the nozzles 6 and from there into a flexible indelible pipe 5, and then by starting the pump 3, water is supplied to the consumer. In this case, the device can be operated on inland waters with high flow rates. In addition, atmospheric air enters through the air intake in the form of a tube 16, which enriches the atmospheric air with oxygen to create a water-air mixture in the chamber 8 of the nozzle 6. In the mixing chamber 8, a mixture having a low density is created. The inlet 7 can be blocked by a fish protection device in the form of a grid (not shown), which protects the fauna of the aquatic environment. Finding the nozzle 6, which has a mushroom shape, with an inlet nozzle equipped with a flexible indelible pipe 5 in the submerged state with the help of the float 10 and the counterweight load 13 is always at a certain depth, provides high-quality water intake from cleaner layers of the water bodies, which allows to increase the level of environmental safety of such reservoirs.

It should be noted that the water is drawn by the flow of water through the chamber 8 of the nozzle 6 and through a flexible indelible pipe 5 when the pump 3 is fixed to the vertical screen 2, and the design of the water intake nozzle ensures the reliability of the device as a whole. Moreover, the device works well when the temperature of the water can vary from 0 to 30 ° C and its dynamic viscosity from 1790 to 800 μPa s.

The course of movement of the float on the guide riser between the fixing stops is determined by the immersion depth of the mushroom-shaped nozzle from the condition that the difference in the levels of the water layer in the retainer provided the necessary stroke of the float to draw water from the middle layers of the reservoir. Retention of the nozzle and the float actuator in connection with a flexible, indelible pipe provides a riser with an adjustable counterweight. Thus, the correspondence between the inflow of water into the pond and the flow rate into the discharge flexible non-crumpled pipe is automatically maintained during operation of the pump for supply to the consumer.

The proposed device has high mobility, a wide range of applications, a relatively simple design and is much more convenient during operation compared to known devices. When using the proposed device, the additional elements marked in the prototype are completely eliminated, and operating costs are also minimized.
