The upper part of turbine module catch wind, the lower part of turbine catch wave, as shown in Fig.3 and Fig.7, when waves hit the water receiving gate then exit at the drainage gate flow through the curved circle and back to front of the water receiving gate and exit outwards. Due to turbine catch wave/wind in the vertical the lower part catch wave, the upper part catch wind make turbine module constantly rotate. Contruction is built in form of zigzag, looks like many triangles, each of line of zigzag from 30 to 40m in length, install 6-8 turbine modules, the turbine module nay which connected to each other at the upper part a horizontal axis 41 with the helical gears 42 engage with cac helical spur wheel) 43 is assembled on top of turbine module in the vertical to increase the rotation and make turbine modules rotate with the same rotation. At two ends of the said horizontal axis is assembled with rotors of generator (see Fig.3). The lower part of helical spur wheel is assembled with turbine pillar by a pair of bearing release and a pair of bearing and is assembled with the pivot of turbine. The bottom of turbine module in the vertical is the underwater section using resin ball-bearing or compressed ball-bearing. Because turbines module is connected together the rotation is the same, when wave hits the front turbine thi the rear turbine still rotates; when wave move to the rear turbine, front turbine still rotate because one shaft connected to turbines modules so that the wavelength hits sequentially but the rotation is not interrupted by the wavelengths so the frequency of generator is stabilized frequency. Because natural tide - wave - wind make turbines rotate, by gears increasing the rotation from 30rpm upto 120rpm.

According to one embodiment of the invention, the said electricity generating turbine system which built far away from the coast from 50 - over 100km have to manufacture the dimeter of turbine from 8 - 9m, the length of the turbine module is produced long or short depend on the depth of the sea, pour reinforced concrete into four pillars 3Ί with dimeters is 2,5m as turbine pillar, each of pillars 3Ί have groove 3 '2 to release turbine down and pull turbine up; built in form of zigzag (zig zag) to catch wave - catch wind in the multi-direction; by having pillars of turbine and having electricity for developing industry and for living so that the industrial city can be built offshore.

According to one embodiment of the invention, system for converting wave- wind derived energy comprising apparatus assembly for converting wave-wind derived energy has blade module placed horizontally, each of the apparatus assembly for converting wave- wind derived energy is 30 - 40m in length, is installed in form of zigzag (zig zag). The system can be built farther away from the coast than turbine system placed vertically. The apparatus assembly for converting wave-wind derived energy placed horizontally has to be poured reinforced concrete into two lozenge shafts, two side of lozenge shaft having 2 grooves to release turbine down and lift turbine up according to tidal level. Because tide goes up and down, an unit for automatically lifting and lowering the turbine according to the tidal water operated by compressed air is required. As shown in Fig.5, the apparatus assembly for converting wave-wind derived energy is placed horizontally being supported at two ends by reinforced concrete pillars with grooves to insert into frame at two ends of turbine. The turbine module assembly placed horizontally can automatically be raised and lowered according to the tidal water by the automatic compressed air operated unit. The unit operated by using float acting as swich under the effect of the change of sea level to rotate viscous hydraulic pump to lift turbine system or lower turbine to an appropriate height to the sea level. When tide rises, floats push the compressed air lock to unlock compressed air and rotate viscous hydraulic pump to push apparatus assembly for converting wave-wind derived energy up, when apparatus assembly for converting wave-wind derived energy is lifted, accordingly it will make floats raised, compressed air is automatically cut when float is heavy enough to pull lock and close compressed air. When tidal fall, another float lower turbine module assembly by float pull lock and discharge of hydraulic Lubricant to lower apparatus assembly for converting wave- wind derived energy.

At two ends energy conversion assembly have bin blade module in the horizontal is installed with rotors of generators which connected to two ends of energy conversion apparatus by the cycle increasing chain gears.

Efficiencies of invention

Advantage of solution of the invention: The multifunction tidal turbine for the system for converting wave-wind derived energy", converting wave/wind energy into electricity energy continuously even when have no nature wind and when wave/wind is small and regain wastewater of the present hydropower constructions and/or hydropower construction with the water column is only 0,3m - 1,5m in height for generating with condition of m3/s is big the capacity is high, overcome the power shortage in areas where electricity can be connected such as in the islands, remote areas, disadvantaged areas and supplement to the national power grid at rush hours. This is green energy, does not affect the environment and not destroy biodiversity. When building the constructions at the coast, it acts as dyke for preventing tsunami. Besides, tidal turbine can be further installed at the diverse terrain of rivers, streams flow from the uptream to sea, help the irrigation in the dry season; modernize the irrigation, hydropower, road traffic; with the water is only 0,3m for generating electricity. Building the contructions by using tidal turbine to disperse flood and against drought and cancel flood power in different regions throughout the territory of Vietnam.

In short, this solution of the invention is completely new and different with the conventional turbines, the contruction is also built dTifferently to the present generator constructions operated by tides and waves - wind. The tidal turbine is kind of turbine for multi-purpose application, multiple benefits; respond to climate change and contribute greatly to social economic development; ensure social security, maritime security and defense.
