Abstract
Floats are constructed to provide an offshore wave calming effect and their movement used to generate electric power via submerged generators. The floats 1 operate the generators 3 by means of toothed rods 2 acting through gearboxes 5. A buoyancy balance is created via central float 7, buoyancy jackets 10, positioned by tie bars 4 and hawsers 6 the whole machine being held by anchor 8 which also provides the means of power distribution.
Description
r i 2332245 WAVE CALMING POWER GENERATOR This invention relates to a wave
calming power generator which may be used in a fixed position or moved from location to location as the need arises The problems of coastal erosion are well known. The most commonly used approach is to build up and reinforce in some way the coast itself This is usually extremely costly, and in the case of shingle beaches needs constant repair to remain effective.
Ile present invention attacks the problem offshore by dissipating wave energy, the energy thus dissipated is used to provide electricity.
According to the present invention there is provided a floa or a number of floats, which activated by waves and thus dissipating their power operate generators by means of toothed rods and gears; a buoyancy balance is created between the floats and buoyancy jackets around the generators to enable the operations to take place.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which:sheet 1. shows a machine with two floats sheet 2. shows a schematic drawing of sheet 1. in isometric form sheet 3. Fig 1. Shows an end elevation of the generator and gearbox. Fig 2. Shows a side elevation of the generator and gearbox Referring to the drawings the machine comprises a number of wave calming floats 1 free to move with wave motion but anchored to a central buoyancy float 7; beneath these are suspended generators 3, contained in buoyancy jackets 10 and operated by a particular float by means of a connecting toothed rod 2 and gearbox 5 which gives continuous rotary motion to the generator regardless of the linear direction of the floats or rods. The generators are maintained in spatial distance from the central float by tie rods 4 fixed centrally by swivel joints 9 which are latched to prevent the generators underrunning the central pivot, and also by anchor hawsers 6 which restrict generator movement to a maximum arc of ninety degrees. The whole machine is anchored to the sea bed by the central anchor 8 which also provides a distribution point for the power via cables 11. Ile ratios between the tie rods 4, the length and angle of toothed rods 2, the length and circular path of the generator 3 due to the hawser 6, must be carefully designed to enable maximisation of movement of the toothed rod and hence, generator, whilst at the same time preventing the bottom end of the toothed rod from hitting the sea bed when either the machine is at low water, or at the bottom of wave motion.
