Description
Technical field
The utility model belongs to a kind of tidal power generation pressure charging system.
Background technique
Existing tidal power generation system is exactly that energy cannot sufficiently be absorbed from ocean current there are a maximum problem, example
If seawater velocity increases to 4 sections from 1 section, the energy of ocean current increases 64 times, existing direct generation of electricity system (the direct band of the hydraulic turbine
Dynamic generator) absorb energy the amplitude of accommodation it is very narrow, energy absorption is insufficient, causes a large amount of energy dissipations, increases payoff period.I
Early period develop utilize Fluid-transmission indirect power generation system, although more larger than the absorption energy amplitude of direct generation of electricity system,
Or a large amount of energy dissipation.
Prior art disadvantage:
1. the energy that existing electricity generation system cannot efficiently use tide.2, existing self booster is broadly divided into two
Kind, one is the commutations with Electronic control pressurized cylinder, but unstable (such as are powered off, electromagnetic coil easy burn-out due to automatically controlled
Deng.) all application ranges are narrow.Second is hydraulic control, and feature is all the setting guidance oil circuit at low-pressure piston, this just makes
At two problems, if there is sealing ring on low-pressure piston, sealing ring is particularly easy to damage, if using clearance seal, it will
Cause to cannot be used for the seawater of low viscosity, while inefficiency.

Ejector pin b (15) and flow stabilizer b (16)；Wherein, ejector pin a (3) one end is suspended from low pressure chamber a (8), and one end resists import list
To the nonreturn valve core of (5) valve a, the spring terminal of check valve a (5) is connected with P mouthfuls, and the other end and the hydraulic control of check valve a (5) can position
One end of reversal valve (1) is connected, while being connected with the import of flow stabilizer a (2), the outlet of flow stabilizer a (2) and atmosphere
It is connected；The other end is also identical connection；
Wherein, under the spring effect of check valve a (5) and under P mouthfuls of pressure, check valve a (5) is constantly in closing, works as work
Stopper rod (9) travels to the left, encounters ejector pin a (3), moves downward ejector pin a (3), opens check valve a (5), such P mouthfuls of high pressure
Seawater becomes the left end that reversal valve (1) can be positioned into hydraulic control, and reversal valve (1) is made to commutate, and such P mouthfuls just enters low pressure chamber a (8)
Make piston rod (9) to right travel, is detached from its ejector pin a (3) and piston rod (9).It is acted on simultaneously in the spring of check valve a (5)
Under, check valve a (5) is closed；The control pressure of reversal valve (1) left end will pass through flow stabilizer a (2) pressure release.
Since reversal valve (1) has positioning action, therefore kept for P mouthfuls just enter low pressure chamber a (8), until commutate next time,
Preferably, the hydraulic control can position commutation position there are two reversal valves (1), and each position has accordingly
Steel ball positioning, thus hydraulic control can position reversal valve (1) and be only possible in left position or right position；When highly pressurised liquid enters booster
When afterwards, into the left-half of booster, highly pressurised liquid can position reversal valve (1) into low pressure chamber a by hydraulic control all the way
(8), highly pressurised liquid enters the valve port of machine control check valve a (4) all the way, and highly pressurised liquid passes through high pressure chest import check valve a (5) all the way
Into high pressure chest a (6), since the spring of high pressure chest Outlet check valves a (7) is softer, so that it may easily enter in HP；Work as high pressure
After liquid enters booster by P mouthfuls, into the right half part of booster, the pressure that the left side of piston rod (9) is subject to is greater than the right side
The pressure in face, then piston rod (9) moves right under the effect of the pressure, and at the same time, the high-pressure fluid of generation is from high pressure chest
Outlet check valves b (11) is flowed into HP, to generate pressurization；
Preferably, in the above process, high pressure chest import check valve b (13) and high pressure chest Outlet check valves a (7) are in and close
Closed state, and high pressure chest import check valve a (5) and high pressure chest Outlet check valves b (11) are in the open state；Until piston rod

And push hydraulic control can position reversal valve (1) valve rod commutation, make hydraulic control that can position reversal valve (1) and be in right position, thus connect P and
Low pressure chamber b (10), so that low pressure chamber b (10) and high pressure chest b (12) are in high pressure, and low pressure chamber a (8) and oil return are connected, and are formed
It is big to make piston rod (9) right atrial pressure for low pressure, and left pressure is small, and then piston rod (9) travels to the left；After travelling a distance,
Piston rod (9) and ejector pin b (15) are detached from, and machine control check valve b (14) is closed under the effect of the pressure, due to do not continue into
Oil, flow stabilizer b (16), but always in pressure release, therefore the right atrial pressure that hydraulic control can position reversal valve (1) is gradually kept to 0, still
Hydraulic control, which can position reversal valve (1), steel ball positioning, so make hydraulic control that can position the always on right position of reversal valve (1), until next
Secondary commutation；To the left when driving, the high-pressure fluid of high pressure chest a (6) is entered piston rod (9) by high pressure chest Outlet check valves a (7)
HP；
During this, high pressure chest import check valve b (13) and high pressure chest Outlet check valves a (7) are in the open state, and high
Pressing chamber import check valve a (5) and high pressure chest Outlet check valves b, (11 are in close state.It is encountered when piston rod (9) travels to the left
Ejector pin a (3) moves right ejector pin a (3), opens machine control check valve a (4), and such highly pressurised liquid, which will enter hydraulic control, to be positioned
The left control terminal of reversal valve (1) is greater than flow stabilizer b due to that can position the flow of control terminal of reversal valve (1) into hydraulic control
(flow of 2 discharges, thus in the control terminal left row that can position reversal valve (1) into hydraulic control at high pressure, and then push hydraulic control
The commutation of reversal valve (1) valve rod can be positioned, makes hydraulic control that can position reversal valve (1) and is in left position, to connect P and low pressure chamber a (8)；
An actuation cycle is completed as a result, has been completed at the same time pressurization, if always on high-pressure fluid at P, booster will work always
Work goes down.
Preferably, when the booster is mechanical commutation booster comprising: high pressure chest import check valve a (21),
Machine control can position reversal valve (22), rocker arm a (23), ejector pin a (24), the second high pressure chest a (25), the second high pressure chest Outlet check valves
