Description
The utility model relates to a kind of electricity generating device, particularly relates to a kind of Wave power generation device.
It is pollution-free to utilize wave to generate electricity as power source, Chinese patent CN1082148 has introduced a kind of Wave power generation device, it by vertically be installed in the buoyancy substrate relatively each limit vertical buoyancy tube with much the oil hydraulic cylinder that has the water inlet that is installed on the crossbar that is connected vertical buoyancy tube is formed, each oil hydraulic cylinder has a box type piston bar that has a water inlet and a folding pressure plate, strut is installed in the bottom of crossbar versatilely, and be plugged in the elongated hole of buoyancy plate, this structure makes that the buoyancy plate can be along the strut vertical movement, the upper end activity of box type piston bar is in the bottom that is connected in the buoyancy plate, and be connected with flexible pipe, the water main of this flexible pipe and pressure collector pipe links, and is provided with the generator of big capacity and small capacity in a side of pressure collector pipe.Its working principle is, when the buoyancy plate is promoted by wave and is for vertical movement, the box type piston bar is vertical movement in oil hydraulic cylinder thereupon also, form the water pump effect, therefore, the seawater that enters oil hydraulic cylinder continues to flow into water main, and then the feed pressure collector pipe, utilizes the driving force that is discharged into current generation when being put into waste water pipe to make generator for electricity generation.This device is the buoyancy pulling sea water hydraulic cylinder that utilizes kickboard, provides press water to drive oil hydraulic motor.In fact framework is impossible be anchored in the deep water of several kms, and problems such as marine in addition interior ripple and ocean current, because framework can not be fixed, under the effect of wave, kickboard just can not be done relative movement with framework, can not the compression piston pump, so can't work at all in the abyssal region.Moreover the stormy waves in the ocean and the one-period of surging are 7～11 seconds, and the per minute number of times is very limited, and therefore, the industrial value of this device must be cherished with fixed attention.
The purpose of this utility model is to provide a kind of and need be fixed in the ocean, utilizes the wave collecting energy, produces pressure oil to hydraulic system and generates electricity, and has the Wave power generation device of industrial value.
The utility model Wave power generation device is achieved in that it comprises the power collecting device.The power collecting device is the associating buoyancy aid that is formed by connecting through rigidity by cell cube.Cell cube is by hollow pontoon; fixing with hollow pontoon upper end has the axis of symmetrical slotted hole steel pipe on it; be enclosed within the counterweight buoyancy aid that the axis steel pipe is outer and slide up and down; be arranged in the axis steel pipe and be fixed on the hydraulic cylinder that high pressure oil oil outlet tube and low pressure oil oil inlet pipe are arranged at its bottom, hollow pontoon upper end; the piston that cooperates with hydraulic cylinder; one end is fixedlyed connected with piston; the piston push rod that the other end is fixedlyed connected with the counterweight buoyancy aid; and one end be fixed on hydraulic cylinder upper end, the waterproofing guaranteeding jacket that the other end is fixed on the piston push rod upper end constitutes.The high pressure oil oil outlet tube is connected with hydraulic system with the low pressure oil oil inlet pipe.Wherein, the other end of piston push rod is to fixedly connected by the symmetrical slotted hole counterweight buoyancy aid outer with being enclosed within the axis steel pipe with key pin with fixedlying connected of counterweight buoyancy aid, on the one hand the counterweight buoyancy aid is slided up and down along the axis steel pipe by key pin, drive piston push rod by key pin again on the other hand and slide up and down with the counterweight buoyancy aid and move up and down, thereby make piston up-down in the hydraulic cylinder.Waterproofing guaranteeding jacket is the foldable waterproof protecting jacket, prevents that seawater from entering hydraulic pressure body cylinder on the one hand, does not influence counterweight buoyancy aid promotion piston push rod on the other hand and moves up and down.The associating buoyancy aid is to constitute by interfixing by the rigidity cant beam between the adjacent cells body, and promptly the two ends of rigidity cant beam are separately fixed on the hollow pontoon of two adjacent cell cubes, have best force way, makes it to form a rigidity associating buoyancy aid that scope is bigger.The associating buoyancy aid floats on big ocean surface, and greater than several wave wavelength, vertically insert in the water by the hollow pontoon that constitutes monomer on the X-Y direction for volume, and length should be greater than 1/4 wave wavelength, so that the associating buoyancy aid is not subjected to the wave effect and floating.The associating buoyancy aid can use global satellite orientation device (GPS) and universally push away nearly device and accurately locate in the ocean.When wave rises, the counterweight buoyancy aid reduces to zero to the active force of associating buoyancy aid from T (weight of counterweight buoyancy aid), when wave falls, the counterweight buoyancy aid increases from zero to T to the active force of associating buoyancy aid, when the quantity of counterweight buoyancy aid is abundant, along with the regular fluctuation of wave large size, its aggregate is a steady state value to the active force of associating buoyancy aid, this steady state value just can guarantee the static of the relative counterweight buoyancy aid of associating buoyancy aid, counter-force is provided, thereby guarantees of the effective compression of counterweight buoyancy aid hydraulic cylinder.
The working principle of the utility model Wave power generation device is that during work, the utility model Wave power generation device is connected with hydraulic system (power generation system).Wave shows as with one climax following another on a vast face, and differential is on a limited area time, show as the variation up and down of water level, the counterweight buoyancy aid shows as with floating about the ripple, be that water holds up the counterweight buoyancy aid in the time of upwards, promptly wave overcomes gravity acting the counterweight buoyancy aid is upwards lifted, and the counterweight buoyancy aid obtains potential energy, and by the key pin that is positioned at axis steel pipe slotted hole piston push rod is pulled upwardly, make hydraulic cylinder suck low pressure oil; When the counterweight buoyancy aid moved downward, because hydraulic cylinder output high pressure oil, when the gravity that only presses down reached certain amount, the counterweight buoyancy aid just may press down piston rod.So when wave descended, the counterweight buoyancy aid did not and then descend, but be subjected to the jacking of hydraulic cylinder to be suspended in the there, diminish up to buoyancy, gravity reaches one regularly, and the counterweight buoyancy aid just begins the acting of falling, the output high pressure oil.The associating buoyancy aid provides counter-force for the oil hydraulic cylinder body.This shows in order to obtain required gravity, need the certain wave of loss high, and the associating buoyancy aid provides counter-force for this reason, make its effective compression, the high pressure oil that pumps enters hydraulic system, and drives generator for electricity generation by oil hydraulic motor, ashore carries by submerged cable.Can control automatically by automatic control system, excessive at wave, wave is big unusually, when wave is less than normal, guarantees the hydraulic system safe operation, steady-working state.
The advantage of the utility model Wave power generation device is 1) pollution-free, energy sources is extensive, and is inexhaustible, use not to the utmost.2) found the factory in the sea, do not tie up land resources.3) technology is simple than water power, thermoelectricity, and construction duration is short.4) cost of electricity-generating is low, can match in excellence or beauty with big water power.5) scale of founding the factory can be big, can be little, and very flexible, and extend very convenient, easy.
