FR2961221A1 - Support unit for attaching e.g. Kerckove type energy recovering device, that is utilized for recovering energy from marine or fluvial current, has mounting points on which chains are fixed, where energy recovery device is attached on chains - Google Patents

Abstract

The support unit has a main buoy rope (2) extending from a mooring (1), where the buoy rope has mounting points (4) on which chains (3) are fixed. An energy recovery device is attached on the chains, where the chains are connected with respect to each other so as to form a frame. An electric case has an electric cable that is used to transport electricity produced by the energy recovery device. The fixation unit has a stuffed buoy with a floater that ensures buoyancy of the stuffed buoy. An independent claim is also included for an energy recovery system comprising an energy recovery device.

Description

The present invention relates to a marine device, for recovering and transporting on land, the electricity produced by one or more apparatuses for recovering the energy of tidal streams, and in particular the recuperators called "Kerckove type 1", without that this is not limited to this type. In a tidal stream, the flow (fig 1 C) goes in one direction for six hours, starting from (fig 1, y) and stopping at oeigl, y 9 point that is called the high slack sea, then go back in the other direction from g 1, y 'to y) for about six hours (we returned to the starting point with what is called the low-water slack). But this flow of alternative water is not linear. After the low-water slack, the current goes to the earth (to the left or to the right depending on the proximity of the earth) and we observe a rotating movement g 1, Cl, C'2, C3 left or right, from (figl, b to b). After the high water mark, it does not go directly deg 1, y). It again makes a circular movement going from g 1, b 'to b,) going through C4, C5, C6, left or right) In terms of marine, it is said that a rising tide current "carries" on land , and that a falling tide stream "carries" off. If we take a mobile energy recovery apparatus of the type "Kerckove Type 1" Uig 2, D), anchored on a single dead body (fig 2, a) and fixed by a single oren (fi'g 2, e), this one will have every twelve hours, performed a complete rotation, and this repeatedly. If we put an electric cable 07g 2, f) going to the collection box (fig2, G), it will wind a turn around deg 2, e) every twelve hours.

The electric cable (fig 2, H) carrying the electricity on land to the point (fig2, K) does not pose any problems, because it winds on the seabed and goes back to (fig2, K) on floor. The present invention aims to solve this big problem. There is still no solution at the moment, the recuperator Kerckove Type 1, does not exist, being the subject, at the moment of a patent application (application 10 00513 of 09 February 2010) . The solution is to make the recuperating apparatus work by 2, (fig3), by "3, f7g 4), by 5, by 6 (fig 5) and by all the possible numbers, but knowing that the larger the number, more the places of implantation are docile to find.The devicepar 2 (fig 3) will be the most used.The recuperators "Kerckove type 1" (fig 3, D) or others, will be stowed, not directly to a dead body, but to a metal buoys 3, L), carrying at their summit a trunnion (fig 3, m) intended to receive the orin of the recuperator, allowing it to turn 360 ° .The buoys (fig3, L) will carry to their around the fasteners which will allow, by means of slings, to maintain in place a mixed buoy (fig3, n) composed of a part necessary for the flotation, and a part for the connection of the electric recovery cables ( Fig 3, P) of the energy produced, this buoy part of an electric cable (fig 3, Q) which rejoins the main land or a larger collector (fig 3, K) through the sea bed. Kerckove Type 1 energy recuperators (fig 3, D - g 4, D - fig 5, D), will receive in their upper part an electric extractor (fig 3, R) rotary waterproof; rotating at 360 °. In summary, the energy recovery apparatus D (Fig. 3D, 4D, 5D) will rotate steadily 360 ° about the axis (Fig. 3, m - 4m - 5m). The so-called "m" axes (g 3, m - 4, m - 5, m) and the buoys that support them, making only a circular displacement flat, without rotation on themselves. The goal being that the electrical box (fig 3, n - jig 4, n -; g 5, n) can move, but does not turn on itself The objective is reached, the electric cable (fig 3.Q g 4, fig 5, Q), which will connect these sets to the firm ground through the bottom of the sea, will not undergo a turning movement. It is therefore possible to recover the energy (contained in with waxed currents over 24 hours out of 4), except for the time of x 3 stages, with the VfunYlei turbines recuperators. You should be able to do this for 3 hours at a time, so that you will be able to handle all the depths of the pelagic system. §A also cry 1, fia. however, it is notbr.

Claims (5)

CLAIMS1) Maritime machine, a universal support working in reciprocating currents called tides, intended to be the geopositioned and pelagic support allowing tidal energy recuperators equipped with unidirectional hydroelectric turbines, to transmit the energy produced by these said recuperators to the place of consumption of this energy, while they themselves undergo, in addition to alternative constraints, random rotational constraints. 2) marine machine according to claim 1, characterized in that it is composed of a central float (fig 3, 4 and fig 5), float divided into two parts, one to ensure its buoyancy with all the appropriate means the other, which can be located in the lower part or in the upper part, intended to receive the electrical connections, somehow a waterproof floating branch box, of extremely strong construction and which will receive in its perimeter hanging systems . 3) Machine according to claim 1, characterized in that if it is constituted by peripheral floats (fig 3, 4 and fig 5) that can be ballasted on demand, a shape and a volume that will adapt in each case, comprising in the lower part an adjustable hooking means (FIG. 3) making it possible to secure it by means of a rope (FIG. 3) to a dead body OEIG3) which will be placed at the bottom of the sea, and which will have at its periphery fasteners that will connect it by slings to other similar floats and to the central float, which will carry at their summit a trunnion (fig 3) equipped with a safety fastening system, allowing them to receive a machine of recovery of the energy of the sea, turning on site at 360 ° of a constant way. 4) Peripheral floats according to claims 1 to 3, characterized in that they will be attached to the energy recovery machines of the current "Kerckove Type 1" or others, which will carry at their summit a curved antenna mounted on an electric contactor watertight rotating 360 ° (fig3, R) which antenna will recover the energy produced by said recuperators and to transmit this energy by the electric cable, the central float serving as a branch box (fig 3) 5) Machine according to all of the preceding claims, characterized in that it is necessary for it to exist that there is at least 2 energy recovery machines "Kerckove Type 1 or 40 others to assemble (fig 3), but also 3 (fig 4) 4, 5, 6 (fig 5), or an infinite number, knowing that the number of recuperators admitted, will depend on the possibility of installation at sea, the state of flatness of the floor of the sea being the main element, but the installation with 2 recuperators will be possible everywhere.
