  • water in a first vessel 16A settles to the same level 58 as in a second vessel 50 communicating therewith through a pipe 28.
  • water pump 18 pumping water out of vessel 16A practically brings water thereto, without provision of additional energy.
  • Fig. 2 illustrates the principle of communicating vessels in a slight different structure.
  • Water pump 18 may pump water directly from pipe 28. Like Fig. 1, energy of water pump 18 is required only above level 58.
  • Fig. 3 depicts a sea water supply system (SWSS), according to one embodiment of the present invention.
  • SWSS sea water supply system
  • a sea water supply system (SWSS) 10 according to the embodiment of Fig. 3 is based on the structure of Fig. 2.
  • SWSS 10 includes a pipe 28 which communicates pump 18 that is located substantially at the sea level, to the depth of the sea 50, which is equivalent to vessel 50 of Fig. 2.
  • SWSS 10 is advantaged by supplying water of the purity of the deep level 88. If applying heat insulation to depth-pipe 28 and allowing speed of flow, SWSS 10 may also provide water having temperature derived from the deep level 88. For example the temperature at the depth is 15 C and the temperature at sea level is 25 C. Thus the water from the depth may expand and raise above the sea level.
  • Fig. 4 depicts a sea water supply system (SWSS), according to another embodiment of the present invention.
  • SWSS 10 of Fig. 4 is based on the structure of Fig. 1.
  • SWSS 10 includes first vessel 16A located on land 56 and depth-pipe 28, which communicates vessel 16A to the depth of the sea 50, which is vessel 50 of Fig. 1.
  • the top level 58 of the water in vessel 16A which is the product vessel, equals sea level 58.
  • Pump 18 may pump water from product vessel 16A into an industrial desalination plant 12, an algae growth plant or another plant, such as for marine agriculture for pharmaceutical applications and for high-tech industries etc., which is located substantially at sea level 58.
  • Depth-pipe 28 is depicted communicating a low inlet 66 of vessel 16A. Depth-pipe 28 crosses the solid ground 20 through a drilled entrance 90 that is at a lower level than sea level 58. Depth-pipe is denoted by numeral 82 at that portion.
  • Fig. 5 is a sea water supply system (SWSS) according to another embodiment of the present invention.
  • Fig. 5 is similar to Fig. 4, except that in order to save the drilling infrastructure of Fig. 2, water pump 18 may pump the water from the depth of the sea to product vessel 16A.
  • Fig. 6 depicts the bottom of the pipe of Figs. 3, 4 and 5, according to one embodiment of the present invention. Even though depth-pipe 28 naturally receives relatively pure water from the deep level 88, depth-pipe 28 preferably includes a particles remover 30 at the bottom thereof, for preventing blocking thereof.
  • Particles remover 30 also holds the bottom of depth-pipe 28. The holding is by anchors 32 at the bottom of the sea, through pedestals 70.
  • Fig. 7 depicts the particles remover of Fig. 6, according to one embodiment of the present invention.
  • the water quality is examined by a sensor 38 at the bottom of pipe 28.
  • Sensor 38 may measure the hydrostatic pressure, temperature and other parameters.
  • depth-pipe 28 is inserted into a tube 72 of particles remover 30, which is normally closed beneath by a normally-closed bottom- valve 48.
  • incoming water can enter depth-pipe 28 from the top only.
  • Sea water coming from the top and turning the direction thereof upwards into depth-pipe 28 leaves its particles gathered in a particles pile 46 laid on normally-closed bottom-valve 48.
  • the length of tube 72 from particles pile 46 to the bottom of depth- pipe 28 is sufficient to prevent vacuuming of the particles upwards.
  • bottom-valve 48 Upon exceeding a pre-determined accumulation of particles pile 46, bottom-valve 48 opens, dropping the particles through outlet 44.
  • the allowed size of particles pile 46 is determined by the weight thereof. A weight of particles pile 46 exceeding that of a weight 36 or a spring force, opens bottom-valve 48 about a hinge 74.
  • a transmitter 42 and a detector 40 detect that particles pile 46 has exceeded the allowed size, for activating a motor 76 to open bottom-valve 48.
  • Fig. 8 depicts the particles remover 30 of Fig. 6, removing the particles pile applying another activity.
  • Particles pile 46 (of Fig. 7) and other zones of depth-pipe 28 may be washed by pushing water from depth-pipe 28 downwards to open bottom- valve 48. This activity may also clean a filter 80, and allow maintenance of product vessel 16A.
  • top valve 78 blocks this water exiting through the top of tube 72. However, upon entering depth-pipe 28 at the normal flow depicted in Fig. 6, the water entering tube 72 from the top thereof opens top valve 78.
  • Fig. 9 details the SWSS of Fig. 4.
  • depth-pipe 28 and the extension 82 thereof provide water of the purity of the deep level 88 to product vessel 16A substantially without consuming any energy. This provision is upon opening faucets 62 and 15 A.
  • depth-pipe 28 and extension 82 thereof provide deep sea water to product vessel 16B upon opening faucets 62 and 15B; similarly, depth-pipe 28 and extension 82 thereof provide deep sea water to product vessel 16C upon opening faucets 62 and 15C.
  • Pump 18 may pump water either from product vessel 16A through faucets 86 and 14A, or from product vessel 16B through faucets 86 and 14B, or from product vessel 16C through faucets 86 and 14C, each to a shared pipe 34, into industrial desalination plant 12, requiring minimal lifting energy.
  • depth-pipe 28 and extension 82 thereof also provide this water to additional product vessels 16B and 16C through faucets 15A, 15B and 15C respectively, and through a central faucet 62, all normally open.
  • Fig. 10 details the SWSS of Fig. 9 while pushing water out. Maintenance preferably may use the pure water of product vessels 16A or 16B or 16C.
  • a pump 22 may pump water from any of product vessels 16A, 16B or 16C into the depth of the sea. Pump 22 is depicted pumping water from vessel 16A through faucet 15A through a faucet 19 to pump 22. From there, pump 22 pushes this water through a faucet 64 into an extraction pipe 26 below the ground, and down into the sea through depth-pipe 28. This extraction may open bottom-valve 48 to clean pipe 28, including dropping particles through outlet 44.
  • water for maintenance may be pumped from the sea at sea level through a piping and filter 24 and a faucet 17. However, after using water from the sea level, the pipes must be washed by flowing water from the depth of the sea.

Abstract

Cette invention concerne, dans un aspect, un appareil d'approvisionnement en eau de mer (10) comprenant (Fig. 3, 4, 5) : une conduite d'eau (28) partant sensiblement du niveau de la mer (58) et atteignant les profondeurs (88) marines (50), et qui achemine l'eau depuis les profondeurs (88) marines (50) pour approvisionner une usine (12) située à terre (56) ; cet appareil améliore la qualité de l'eau provenant des profondeurs (88) marines (50) en utilisant le principe des vases communicants plutôt que la consommation d'énergie, ce qui permet d'économiser des infrastructures massives de pompage et de prétraitement, et donc de faire des économies globales.
