The development trend of the fixed Wave-activated power generation equipment of following sea bed is: mooring cost is low, close to rigid fixing, input cost is low, efficiency is high, low, the easy installation of construction cost, can keep in repair at the water surface.Only efficient height, fully could seize wave energy; Only have low, the easy installation of construction cost, can keep in repair at the water surface, overall cost just can reduce, and just has commercial exploitation.
Summary of the invention
The utility model aims to provide a kind of combining efficient rate, particularly in the face of climax, low tide can work in the same old way, and the cost also low-down Wave-activated power generation equipment with anchor chain automatic regulating apparatus.There is tide in all marine sites, the whole world, and some tidal ranges are very large, reach 8-9 rice, such as, in Britain; The tidal range of coastal area of china is between 2.5-3.5 rice.Due to Wave-activated power generation equipment only utilize 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 seize wave energy effectively.In order to adapt to tidal range, the support of present all fixed Wave-activated power generation equipments is all very long, is in order to acting buoyancy aid can be worked at low tide, high water time like this.Support is long, and the cost increased for the fixed Wave-activated power generation equipment of piling is not also very large; But for seabed anchor fixed pattern Wave-activated power generation equipment, cost will increase a lot.Because support is long, mean that center of gravity is high; In order to balance center of gravity, fulcrum will do very wide, just as television tower runners, and like this could be across the sea floating reposefully.The utility model is owing to have employed anchor chain automatic regulating apparatus, by winch folding and unfolding wirerope or anchor chain, attached body can be allowed with tide oscilaltion, all the time certain position of the water surface is fixed on, like this, support just can not long, still can ensure that acting buoyancy aid has enough spaces, thus can seize highest wave energy.Because support is not long, attached body is under the prerequisite of satisfied acting buoyancy aid needs, and just can do little, overall cost will be very low as far as possible.Again owing to utilizing automatic anchoring device thereof, attached body can be allowed by anchor chain or wirerope is rigid is fixed on sea bed, attached like this body just can accomplish absolute rest substantially, efficiency would not be reduced because of attached moving up and down of body with the relative movement of acting buoyancy aid, acting buoyancy aid can be allowed to obtain maximum relative travel, thus make most effective.Because efficiency is high, cost is low, the utility model is made to have good commercial value.
Working principle of the present utility model:
Experiment proves: when the power pullling buoyancy aid is downwards greater than buoyancy, buoyancy aid meeting submerged, the buoyancy of buoyancy aid and the pulling force of anchor chain reach balance, and 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, and only all around can swing with wave.We install the support surfaced on this buoyancy aid, and entirety will become attached body; The acting buoyancy aid allowing another rise and fall on the waves again and support relative movement, will produce power; This transformation of energy is become electric energy, is exactly Wave-activated power generation equipment.
As Fig. 1, the utility model is made up of attached system 1, acting buoyancy aid 2, gravity anchor 3, anchor chain automatic control tegulatingdevice 4, power generation system 5.
Attached 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 the distance of sea bed time, attached system 1 will be drawn in water, and the attached buoyancy of system 1 and the pulling force of anchor chain reach balance, Floating System 1 can be still in water, can not rise and fall on the waves.Acting buoyancy aid 2, owing to not being fixed on sea bed, with wave dipping and heaving, can will produce relative movement with attached system 1 like this, will produce power.The power generation system 5 being installed on the frame upper of attached system 1 produces electric energy with the motion of acting buoyancy aid 2 due to its tooth bar or hydraulic rod.Anchor chain automatic control tegulatingdevice 4 is according to the change of tide, the length of hawser can be adjusted, thus allow the buoyancy aid of attached system 1 forever at certain point undersurface, stable distance is almost kept with the water surface, ensure that acting buoyancy aid 2 moves in certain fixed range of support 102, bottom the support 102 that can not hit attached system 1 because of the time of low water, also the top of support 102 can not be hit because of high water time, thus support is damaged, there are enough working strokes simultaneously, allow power generating equipment export maximum power.
The beneficial effect that the utility model has:
1, utilize the buoyancy of the pulling force of anchor chain and attached body, attached system 1 almost just can be allowed to have linking close to rigidity with sea bed, can not produce with the change of wave and move up and down; This is the effect that other floating type Wave-activated power generation equipment is dreamed of.
2, like this, attached system 1 just can do less, as long as its gross buoyancy is greater than the gravity+insurance buoyancy of the gravity+acting buoyancy aid 2 of self, that's all; Need not as other floating generator, enough stable and do very large in order to allow attached body obtain.
3, because attached system 1 is less, so the overall cost occupied is just little, close to the cost of acting buoyancy aid 2; And the attached body of traditional floating type Wave-activated power generation equipment generally occupies more than 80% of total volume.
4, because total volume is little, buoyancy is little, and the pulling force of such fixed equipment is also little, and gravity anchor 3 is just little, and the erection unit of needs is just less, and mounting cost will significantly reduce.
5, make use of anchor chain automatic control tegulatingdevice, the harmful effect that equipment can be made very well to eliminate tidal range cause.
