Embodiment
Like Fig. 1, Fig. 2, Fig. 4, shown in Figure 6; A kind of Wave power generation method involved in the present invention, it is made up of main frame 3, mobile framework 18, hoist cylinder 4, power buoyancy aid 11, power cylinder 9, high pressure liquid container 1, low pressure liquid tank 19, multistage bending moment pump 21 and generator 22 etc.
Because wave 10 is along 14 fluctuations (Fig. 1) of surge direction; Drive power buoyancy aid 11 through universal head 16 (Fig. 3); Power cylinder 9 is moved up and down along guide pillar 15 through slide bushing 17, and when power buoyancy aid 11 moved from bottom to top, power moved power cylinder 9 through universal head 16 from bottom to top; Power cylinder 9 compression hydraulic oil flow to high pressure liquid container filler opening 2 through power cylinder oil outlet one-way valve 7; When power buoyancy aid 11 moved downward, power cylinder 9 sucked the hydraulic oil in the low pressure liquid tank 19 in the power cylinder 9 through low pressure liquid tank oil outlet 5, power cylinder filler opening one-way valve 8, accomplishes a circulation.
A certain proportion of air is arranged in the high pressure liquid container 1, be used to cushion impact force, pressure and the flow of hydraulic oil, make the more steady of multistage bending moment pump 11 operations, the output oil pipe 24 of high pressure liquid container 1 is connected respectively to the input end of the electrically-controlled valve 23 of each pump.
Multistage bending moment pump 21 is composed in series by a plurality of self-contained pumps; The input end of each pump all has independently electrically-controlled valve 23; The Push And Release of control pump; With the gear pump is example, and it is made up of gear pump main shaft 25 (Fig. 4), the pump housing 26, high pressure oil import 27, gear pump pump tooth 28 etc., and the capacity of pump increases progressively than being: 1: 2: 4: 8: 16 ... (Fig. 5).
When wave 10 changed from small to big, pressure and flow in the high pressure liquid container 1 increased gradually, and multistage bending moment pump 21 moves according to system's control law as follows:
The first step is opened the electrically-controlled valve (Fig. 1) of the minimum one-level pump 29 (Fig. 6) of flow, and high-pressure and hydraulic oil flows into one-level pump filler opening 32, makes 29 work of one-level pump;
Second step was opened the electrically-controlled valve of two stage pump 30, closed the electrically-controlled valve of one-level pump 29 and triplex 31 simultaneously, and high-pressure and hydraulic oil flows into two stage pump filler opening 33, made two stage pump 30 work;
The 3rd step was opened the electrically-controlled valve of one-level pump 29 and two stage pump 30 simultaneously, closed the electrically-controlled valve of triplex 31, and high-pressure and hydraulic oil flows into one-level pump filler opening 32, two stage pump filler opening 33, made one-level pump 29, two stage pump 30 work;
The 4th step was opened the electrically-controlled valve of triplex 31, closed the electrically-controlled valve of one-level pump 29 and two stage pump 30 simultaneously, and high-pressure and hydraulic oil flows into triplex filler opening 34, made triplex 31 work;
The 5th step was opened the electrically-controlled valve of one-level pump 29 and triplex 31 simultaneously, closed the electrically-controlled valve of two stage pump 30, and high-pressure and hydraulic oil flows into one-level pump filler opening 32, triplex filler opening 34, made one-level pump 29, triplex 31 work;
The 6th step was opened the electrically-controlled valve of two stage pump 30 and triplex 31 simultaneously, closed the electrically-controlled valve of one-level pump 29, and high-pressure and hydraulic oil flows into two stage pump filler opening 33, triplex filler opening 34, made two stage pump 30, triplex 31 work;
