Abstract

The invention relates to a hydraulic pressure type tidal energy power-generating device, in particular to a power-generating device for performing hydraulic transmission by utilizing tidal energy. The hydraulic pressure type tidal energy power-generating device is composed of a caisson, a hydraulic cylinder, a piston, a connecting rod, a floating body, a water outlet pipe and a power generator, wherein a one-way water inlet valve and a one-way water outlet valve are respectively arranged on the hydraulic cylinder and at the lower part of the hydraulic cylinder. When ebb and flow occur, the floating body drives the piston to vertically move so as to press out water in the hydraulic cylinder through the one-way water inlet valve and the one-way water outlet valve, and the pressed high-pressure water drives a power generator to generate power. The hydraulic pressure type tidal energy power-generating device has the benefits of simple structure, high easiness in construction and mounting, lower cost, high energy conversion efficiency, large power generation quantity, no need of damming and no influence on environment. The power generator is not corroded by seawater due to absence in the seawater and is easy to overhaul.

Description

Water pressing tidal-energy electric generator set
technical field:
The present invention relates to a kind of tidal-energy electric generator set, especially a kind of tidal energy that can utilize carries out the water pressing tidal-energy electric generator set generated electricity.
background technique:
At present, known tidal-energy electric generator set be at harbour, bay builds gate dam, forms tidal power station reservoir, and controls the turnover of seawater, makes that storehouse is inside and outside produces water-head, under certain water-head, current are generated electricity by hydraulic turbine generator.But this electricity generating device not only engineering work load is huge, and construction cost is high, also environment can be affected.
summary of the invention:
In order to solve the deficiency of current tidal-energy electric generator set, the invention provides a kind of water pressing tidal-energy electric generator set can built on shallow sea.This apparatus structure is simple, and build and install easily, cost is lower, and neither needing to build a dam also can not affect environment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water pressing tidal-energy electric generator set, by caisson, fluid cylinder, piston, connecting rod, buoyancy aid, outlet pipe and generator are formed, it is characterized in that: described caisson is fixed on bottom shallow sea, the fluid cylinder of piston is had in installing one above caisson, a ball float is established above fluid cylinder, certain mass is added in buoyancy aid, be connected by a metallic rod between buoyancy aid with piston, one-way water inlet valve is established respectively above fluid cylinder, upper one-way water outlet valve and upper unidirectional outlet pipe, fluid cylinder bottom sides sets one-way water inlet valve respectively, lower one-way water outlet valve and lower unidirectional outlet pipe, the other end of upper unidirectional outlet pipe and lower unidirectional outlet pipe faces toward the impeller of generator.
According to described water pressing tidal-energy electric generator set, it is characterized in that: the height of described fluid cylinder is greater than local extreme tide range, prevent buoyancy aid from rising excessively, damage whole device.
The invention has the beneficial effects as follows, this apparatus structure is simple, and build and install easily, cost is lower, and energy conversion efficiency is high, and neither needing to build a dam also can not affect environment.Generator not in the seawater, not by the corrosion of seawater, is easy to again maintenance.
accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is unitary construction figure of the present invention.
One-way water inlet valve, 12 generators on unidirectional outlet pipe, 11 on one-way water outlet valve, 10 on 1 caisson in figure, 2 fluid cylinders, 3 pistons, 4 metallic rod, 5 buoyancy aids, 6 times one-way water inlet valves, 7 times one-way water outlet valves, 8 times unidirectional outlet pipes, 9.
embodiment:
As shown in the figure, caisson 1 is fixed on bay, and fluid cylinder 2 is fixed on above caisson 1, establishes piston 3 in fluid cylinder 2, and metallic rod 4 connects the buoyancy aid 5 above piston 3 and fluid cylinder 2.On fluid cylinder 2, be provided with one-way water inlet valve 11 and upper one-way water outlet valve 9, upper one-way water outlet valve 9 connects unidirectional outlet pipe 10.The bottom of fluid cylinder 2 is provided with lower one-way water inlet valve 6 and lower one-way water outlet valve 7, and lower one-way water outlet valve 7 connects lower unidirectional outlet pipe 8.The other end of upper unidirectional outlet pipe 10 and lower unidirectional outlet pipe 8 faces toward the impeller of generator 12.The height of fluid cylinder 2 is greater than local extreme tide range, prevents buoyancy aid 5 from rising excessively, damages whole device.
Working principle of the present invention is: as the tide rises, buoyancy aid 5 drives piston 3 to rise, at this moment the lower one-way water outlet valve 7 of fluid cylinder 2 bottom is closed automatically, lower one-way water inlet valve 6 is opened automatically into water, upper one-way water inlet valve 11 above fluid cylinder 2 is closed automatically, upper one-way water outlet valve 9 is opened automatically, and the high pressure water on piston 3 top sprays through upper unidirectional outlet pipe 10, and surge generator 12 generates electricity.When ebb tide, buoyancy aid 5 drives piston 3 to move downward, and the upper one-way water inlet valve 11 at this moment above fluid cylinder 2 is opened automatically, and seawater enters fluid cylinder 2, and upper one-way water outlet valve 9 is closed automatically; The lower one-way water inlet valve 6 of fluid cylinder 2 bottom is closed automatically, and lower one-way water outlet valve 7 is opened automatically, and the high pressure water of fluid cylinder 2 bottom sprays through lower unidirectional outlet pipe 8, and surge generator 12 generates electricity.
