Abstract

Tidal-driven seawater pump (100) with a socket (111) arranged to rest upon the seabed. A buoyance means (101) is connected to a piston (102) accommodated slidably in a closed cylinder (108) with a lower compartment (109) with top wall (112). A seal (113) is provided along the periphery of the piston (102). The cylinder (108) exhibits an upper inlet valve (106A) and a lower inlet valve (106B), and an outlet for pumping seawater in the cylinder (108) to the sea surface either through upper outlet valve (107A) or lower outlet valve (107B). The buoyance means (101) is accommodated slidably in a housing (110) having an upper compartment (117) with an upper open end (110A), and having a lower end delimited by the top wall (112) of the lower compartment (109). The housing (110) is provided with a number of flow apertures (115) to allow exchange of seawater between the environments and the upper compartment (117) of the protective housing (110).

Claims (6)

Claims
1. Tidal-driven seawater pump (100) with a socket (111) arranged to rest upon the seabed, comprising: a buoyance means (101) connected to a piston (102) through a substantially vertically extending stiff connector means (103), wherein the piston (102) is accommodated slidably in a closed cylinder (108) having a top wall (112) and defining a lower compartment ( 109), wherein a seal (113) is provided along the periphery of the piston (102) and the cylinder (108) wall, and wherein the cylinder (108) at its outside exhibits an inlet for supply of seawater from the environments to either an upper inlet valve (106A) at the top wall (112) or a lower inlet valve (106B) and further to the internal closed compartment (109), and an outlet to allow seawater accommodated in the lower compartment (109) of the cylinder (108) to be pumped to a reception onshore or at the sea surface either through an upper outlet valve (107A) or a lower outlet valve (107B); characterized in that the buoyance means (101) is accommodated slidably in a substantially vertically extending elongate protective housing (110) having an upper compartment (117) with an upper open end (110A), and having a lower end delimited by the top wall (112) of the lower compartment (109), wherein the protective housing (110) is provided with numerous flow apertures (115) to allow exchange of seawater between the environments and the upper compartment (117) of the protective housing (110).
2. The tidal-driven seawater pump (100) of claim 1, wherein the buoyance means (101) is formed of a solid material having negative buoyancy, and having a recess in the underside of the buoyance means (101) defining a cavity (114) with means for supplying or evacuating air from the cavity (114) when the buoyance means (101) is submerged .
3. The tidal-driven seawater pump (100) of claim 1, where the buoyance means (101) is formed of concrete.
4. The tidal-driven seawater pump (100) of claim 1, wherein the top wall (112) of the lower compartment (109) is arranged movable in the axial direction within the cylinder (108) and exhibits means for locking or releasing the top wall (112) at desired elevation inside the cylinder (108).
5. The tidal-driven seawater pump (100) of claim 4, wherein the cylinder (108) exhibits a number of additional inlet valves (106A', 106A") distributed at a mutual distance in the height direction, and a number of additional outlet valves (107A', 107 A") distributed at a mutual distance in the height direction .
6. The tidal-driven seawater pump (100) of any one of the preceding claims, wherein the inlet valve (106A) is a non-return valve preventing seawater from flowing out of the lower compartment (109) in the cylinder (108), and wherein the outlet valve (107A) is a non-return valve preventing seawater from flowing into the lower compartment (109) in the cylinder (108).
