Abstract
The invention relates to wave power generation equipment with an automatic anchor chain adjusting device. The wave power generation equipment is low in building cost. According to the technical scheme, the wave power generation equipment comprises a floating body system, acting floating bodies, a gravity anchor, the automatic anchor chain adjusting device and a power generation system. The floating body system 1 is pulled into water by the gravity anchor 3. When buoyancy and tensile force of each anchor chain are balanced, the floating body system 1 can keep still in the water and cannot rise and fall along with waves. The power generation system 5 installed on the floating body system 1 can generate electric energy due to the fact that a rack or hydraulic rod of the power generation system can move along with the acting floating bodies 2. The automatic anchor chain adjusting device 4 can adjust the length of each anchor chain according to tidal changes, and therefore the floating bodies of the floating body system 1 can be kept at certain points under the water all the time and can almost keep a stable distance with the water surface, and the effect that the acting floating bodies 2 can move within a certain fixed range of a support is guaranteed. The wave power generation equipment is low in building cost, easy to manufacture and install and convenient to repair, thereby having great commercial value.
Description
Technical field
The present invention relates to the use of the device that adjustment Wave-activated power generation equipment adapts to tidal range, make Wave-activated power generation equipment low particularly to one kind
The time of tide can work, in the equally efficient anchor chain automatic regulating apparatus of high water time.
Technical background
There is following problem in actual applications in Wave-activated power generation equipment at present: floatation type Wave-activated power generation equipment completely is bulky,
Attached body is more much larger than acting buoyancy aid, leads to cost to increase it is difficult to commercially valuable；The fixed or seabed anchoring type of piling, is subject to again
To the impact of tide, in order to be able to take into account climax, low tide equally can do work, and is necessary for lengthening fixing device, allows well acting buoyancy aid not
Affected by tide, can normal work；Construction cost is so also led to increase.For example, single-point popular in the world at present floats
Body Wave-activated power generation equipment, attached body is very long, very big, heavy at one end to hydrostatic-layer, play the effect of damping；Other end must be with one
Very thick pipe and acting buoyancy aid insertion, limit the range of movement of acting buoyancy aid；And, the damping buoyancy aid of hydrostatic-layer be not with
The rigid link of sea bed, still can not accomplish absolute rest, also can move up and down with acting buoyancy aid, simply amplitude is much smaller；So
Acting buoyancy aid is just little with the distance of relative movement of attached body, and output will reduce, and attached body, due to very long, larger, is also led
Cause cost not low it is difficult to commercially valuable.
The development trend of the fixed Wave-activated power generation equipment of following sea bed is: mooring low cost, close to rigid fixation, throw in low cost,
Efficiency high, construction cost is low, easy installation, can keep in repair in the water surface.Only efficiency high, could fully seize wave energy；Only
Construction cost is low, easy installation, can keep in repair in the water surface, and totle drilling cost just can reduce, and just has commercial exploitation.
Content of the invention
The present invention is intended to provide one kind has high efficiency concurrently, particularly can work in the face of climax, low tide in the same old way, and cost is also non-
The often low Wave-activated power generation equipment with anchor chain automatic regulating apparatus.There is tide in all marine sites in the whole world, and some tidal ranges are very big, reach
To 8-9 rice, such as in Britain；The tidal range of coastal area of china is between 2.5-3.5 rice.Because Wave-activated power generation equipment only utilizes surface
Wave energy, so, the problem of fixed Wave-activated power generation equipment overriding concern be how to adapt to low tide, high water time can be seized effectively
Take wave energy.In order to adapt to tidal range, the support of currently all fixed Wave-activated power generation equipment is all very long, is so to allow acting
Buoyancy aid can work in low tide, high water time.Support is long, and the cost increasing for fixed Wave-activated power generation equipment of driving piles is not also very
Greatly；But, for seabed anchoring type Wave-activated power generation equipment, cost will increase a lot.Because support length is it is meant that center of gravity is high；
In order to balance center of gravity, fulcrum will be made very wide, just as television tower runners, so could smoothly float across the sea.
The present invention, due to employing anchor chain automatic regulating apparatus, by hoist engine folding and unfolding wirerope or anchor chain, can allow attached body upper and lower with tide
Lifting, be fixed on certain position of the water surface all the time, so, support just can be made not long, remain to ensure do work buoyancy aid have enough
Space, such that it is able to seize highest wave energy.Because support is not long, attached body does work on the premise of buoyancy aid needs in satisfaction,
Just can be made small, overall cost will be very low as far as possible.Again due to utilizing automatic anchoring device thereof, can allow attached body pass through anchor chain or
Wirerope is rigid to be fixed on sea bed, and so attached body just substantially can accomplish absolute rest, would not with the relative motion of acting buoyancy aid
Reduce efficiency because of attached moving up and down of body, acting buoyancy aid can be allowed to obtain maximum relative travel, so that efficiency highest.
Because efficiency high, low cost are so that the present invention has good commercial value.
The operation principle of the present invention:
Experiment proves: when the power pullling downwards buoyancy aid is more than buoyancy, buoyancy aid can submerged, the buoyancy of buoyancy aid and the pulling force of anchor chain
Reach balance, buoyancy aid will be still in certain point in water because of the length of anchor chain, buoyancy aid would not rise and fall on the waves, only can be with wave
All around swing.We, in this buoyancy aid support surfacing installed above, integrally will become attached body；Allow another again
The acting buoyancy aid that can rise and fall on the waves and support relative motion, will produce energy；This energy is converted into electric energy it is simply that
Wave-activated power generation equipment.
As Fig. 1, the present invention is by attached system system 1, acting buoyancy aid 2, gravity anchor 3, anchor chain self-checking device 4, electricity generation system 5
Composition.
Attached system system 1 is held by anchor chain 401 by gravity anchor 3, when anchor chain 401 be shorter in length than the water surface to sea bed apart from when,
Attached system system 1 will be drawn in water, and the attached buoyancy of system system 1 and the pulling force of anchor chain reach balance, and Floating System 1 can be static
In water, will not rise and fall on the waves.Acting buoyancy aid 2, due to being not affixed to sea bed, can thus can with wave dipping and heaving
With attached system system 1 generation relative motion, energy will be produced.Be installed on attached system system 1 frame upper electricity generation system 5 by
Produce electric energy in its tooth bar or hydraulic stem with the motion of acting buoyancy aid 2.Anchor chain self-checking device 4 according to the change of tide,
The length of hawser can be adjusted, thus allow attached system system 1 buoyancy aid forever in certain point undersurface, almost keep stable with the water surface
Distance it is ensured that acting buoyancy aid 2 move in certain fixed range of support 102, attached system will not be hit because of the time of low water
Support 102 bottom of system 1, also will not hit the top of support 102 because of high water time, thus damaging to support, with
When have enough working strokes, allow generating equipment output maximum power.
The invention has the benefit that
1st, utilize the pulling force of anchor chain and the buoyancy of attached body, attached system system 1 almost just can be allowed to have linking close to rigidity with sea bed,
Up and down motion will not be produced with the change of wave；This is the effect that other floatation type Wave-activated power generation equipments are dreamed of.
2nd, so, attached system system 1 just can be made less, as long as its gross buoyancy is more than the weight of the gravity of itself+acting buoyancy aid 2
Power+insurance buoyancy it is possible to；Not necessarily like other floating generators like that, in order to allow attached body obtain enough being stably made
Very big.
3rd, because attached system system 1 is less, so the totle drilling cost occupying is just less, close to the cost of acting buoyancy aid 2；And it is traditional
The attached body of floatation type Wave-activated power generation equipment typically occupies more than the 80% of cumulative volume.
4th, due to cumulative volume less, less, the pulling force of such fixing equipment is also little for buoyancy, and gravity anchor 3 is just little, needs
Installation equipment is just less, and mounting cost will be greatly lowered.
5th, make use of anchor chain self-checking device, equipment can be made very well to eliminate the harmful effect that tidal range causes.
