Existingly tidal current energy generating equipment is fixed on water-bed method of construction and mainly carries out explosion at the bottom by workmen, ram precast concrete pile and be fixed.But, in order to ensure the generating efficiency of tidal current energy generating equipment, usually need electricity generating device to be arranged on the very anxious place of current.Due to water velocity quickly, underwater construction not only reliability is low, and workmen also can be abnormally dangerous.
Being different from other field king-pile is construct and be used in comparatively flat water, and axially support and fixation are only played in these stakes, in marine tidal-current energy power field, because current can produce very large radial impact power, in order to ensure the strong degree of stake, the cross-section area of every pile must be guaranteed.In other words, cross-section area very large stake guarantee tidal current energy generating equipment is not disturbed by rapid stream, makes it be completely fixed in the bottom.But, add the cross-section area of stake, the water side of stake is also increased considerably, namely add the lifting surface area of each pile by water flow impact pressure.Increase owing to meeting power area, reduce the fastness even counteracting overstriking stake and bring on the contrary, and difficulty of construction also increases greatly.Therefore, the existing tidal current energy generating equipment being fixed on the bottom all exists fixing not firm, the problem that construction is complicated, dangerous, cost is too high.Existing tidal current energy generating equipment is owing to being subject to the restriction of method of construction, and cannot maximize, cost remains high, and causes the technology barriers of the tidal current energy generating equipment commercial operation that the mankind cannot break through.

Especially horizontal axis hydraulic turbine generator, due to its all devices (comprising impeller and generator) all under water, therefore the maintenance of horizontal axis hydraulic turbine generator is more difficult, and cost is higher.Therefore, even if the generating efficiency of horizontal axis hydraulic turbine generator is higher than vertical shaft hydraulic turbine generator, but horizontal axis hydraulic turbine generator still cannot commercialization.But the technician in current power generation with marine energy field have ignored the improvement to maintenance mode.
In addition, traditional tidal current energy generating equipment generally only adopts two hydraulic turbine generators at the most.But only adopt one or two hydraulic turbine generator, in order to improve generated output, the diameter of usual impeller needs to manufacture very large, greatly can reduce the rotating speed of impeller like this, increase moment of torsion, cause the friction between central shaft and gear-box to strengthen, the cost of central shaft and gear-box is climbed to a higher point simultaneously.In addition, the scale of whole electricity generating device also can be restricted, and the cost of electricity generating device can remain high, and constrains the development of tidal current energy generating equipment.
But the technician in current power generation with marine energy field also exists technology prejudice, only focus on how the impeller wheel portion of hydraulic turbine generator is done greatly or to improve to improve to the structure of impeller blade the generated output of single hydraulic turbine generator by research and development.Nobody research in current related domain, how under the prerequisite not changing impeller, improves generated output and reduces costs and use with applicable business.

Due to the impeller 21 of horizontal axis hydraulic turbine generator 2 and generator 22 all under water, therefore, if horizontal axis hydraulic turbine generator 2 breaks down, needs keep in repair in the sea by traditional tidal current energy generating equipment.Such maintenance is very difficult and expense is huge.But, built-in module can directly repair or replace from marine taking-up by the tidal current energy generating equipment 100 being fixed on the bottom of the present utility model, realize quick-replaceable and the maintenance of being fixed on water-bed tidal current energy generating equipment 100, greatly reduce maintenance cost, the commercialization of being fixed on water-bed tidal current energy generating equipment 100 is achieved.
At least one horizontal axis hydraulic turbine generator 2 correspondence is installed on every root rotating shaft 3, and at least one rotating shaft 3 correspondence is installed on each inner gimbal 12.At least three driver elements 4 respectively connection rotating shaft 3 rotate with drive shaft 3.In the present embodiment, the axial direction of rotating shaft 3 is perpendicular to horizontal plane P.But the utility model is not limited in any way this.In other embodiment, the axial direction of rotating shaft 3 can be parallel to horizontal plane P.An inner gimbal 12 forms built-in module jointly with corresponding rotating shaft 3 and horizontal axis hydraulic turbine generator 2.In the present embodiment, two horizontal axis hydraulic turbine generator 2 correspondences are installed on a rotating shaft 3, rotating shaft 3 and correspond to an inner gimbal 12.But the utility model is not limited in any way this.In other embodiment, a built-in module can have many rotating shafts 3 and multiple horizontal axis hydraulic turbine generator 2.
By arranging rotating rotating shaft 3, such that no matter current whichaway flows into, the impeller 21 of horizontal axis hydraulic turbine generator 2 all the time towards current, thus guarantees maximum generated output.Because the water (flow) direction of flood tide and ebb tide is contrary, the water-bed tidal current energy generating equipment 100 that is fixed on therefore with rotatable rotating shaft 2 is particularly useful for utilizing tidal energy to generate electricity.In the present embodiment, as shown in Figure 1, the top cross section of inner gimbal 12 is the rectangle that centre has crossbeam.The two ends of rotating shaft 3 are arranged on middle crossbeam rotationally.
In practical application, when current flow to the tidal current energy generating equipment 100 being fixed on the bottom along the water (flow) direction D shown in Fig. 1, driver element 4 does not operate.Now, the impeller 21 of horizontal axis hydraulic turbine generator 2 is towards current.When current flow to along the direction (looking from Fig. 1 as from top to bottom) that water (flow) direction D is contrary the tidal current energy generating equipment 100 being fixed on the bottom, driver element 4 drive shaft 3 is rotated, thus drive horizontal axis hydraulic turbine generator 2 to revolve turnback, make impeller 21 from changing into upward down, to ensure that the impeller 21 of horizontal axis hydraulic turbine generator 2 is all the time towards current.This kind of situation is particularly useful for utilizing tidal power, ensure that maximum generated output.
In the present embodiment, be fixed on water-bed tidal current energy generating equipment 100 and also comprise at least three air guide sleeves 8, be fixed on inner gimbal 12 or external frame 11, air guide sleeve 8 is positioned at the upstream of horizontal axis hydraulic turbine generator 2 along water (flow) direction D accordingly.Preferably, be fixed on water-bed tidal current energy generating equipment 100 and also comprise at least six air guide sleeves 8 arranged axisymmetricly, be fixed on inner gimbal 12 or external frame 11, air guide sleeve 8 lays respectively at the upstream and downstream of horizontal axis hydraulic turbine generator 2 along water (flow) direction D.
In the present embodiment, the cylindrical shape that air guide sleeve 8 reduces gradually for diameter.Specifically, the crossbeam of every two air guide sleeves 8 in the middle of inner gimbal 12 axisymmetricly.As shown in Figure 1, be arranged in the air guide sleeve 8 of figure top, its diameter from top to bottom successively decreases, and be positioned at the air guide sleeve 8 of below, its diameter from bottom to top successively decreases.By arranging air guide sleeve 8, current are all concentrated guiding horizontal axle hydraulic turbine generator 2, make the impeller 21 of horizontal axis hydraulic turbine generator 2 stressed larger, rotating speed is faster, thus improves generating efficiency.But the utility model is not limited in any way the quantity of air guide sleeve 8 and shape.In other embodiment, air guide sleeve 8 can be first that square then diameter reduces transition for cylindric.
In the present embodiment, be fixed on water-bed tidal current energy generating equipment 100 and also comprise at least two fence 92, two fence 92 are arranged in inner gimbal 12 or external frame 11(Fig. 1 not to be drawn), at least two fence 92 lay respectively at the upstream and downstream of horizontal axis hydraulic turbine generator 2 along water (flow) direction D.Fence 92 is perpendicular to water (flow) direction D and perpendicular to horizontal plane P.By arranging fence 92, seabed rubbish effectively can be avoided to be involved in horizontal axis hydraulic turbine generator 2, thus realize the protection to horizontal axis hydraulic turbine generator 2, extend the working life of horizontal axis hydraulic turbine generator 2.As shown in Figure 3, fence 92 has lattice type lines.But the utility model is not limited in any way this.
How be fixed on water-bed method of construction below in conjunction with the tidal current energy generating equipment 100 provided by the present embodiment makes construction safer, convenient, firm to illustrate tidal current energy generating equipment of the present utility model.
First, make external frame 11, many outer sleeves 5 are fixed on external frame 11, respectively in the one-body molded multiple reduction resistance to water-flow structure 112 of the side position that meets water of many outer sleeves 5, many inner sleeves 6 are inserted accordingly in many outer sleeves 5, buoyancy aid 7 is fixed on external frame 11, and these are all carry out on the coast.In the present embodiment, every root inner sleeve 6 comprises the first inner sleeve 61 and the second inner sleeve 62 be separated from each other.Insert in outer sleeve 5 by the first inner sleeve 61, the second inner sleeve 62 wouldn't insert.The internal diameter of outer sleeve 5 is only slightly larger than the external diameter of the first inner sleeve 61.
Then, external frame 11 is inserted in water, in water, pull external frame 11 to infield.In practical application, because tidal current energy generating equipment 100 will ensure efficient generating, therefore the infield of tidal current energy generating equipment 100 needs to be selected in the larger waters of water velocity, and distance bank, infield has not short distance.
In prior art, be first with ship, whole electricity generating device loading is transported to infield, and then by crane barge ship, electricity generating device hung in water, sink under water.Need long period of soaking in water due to electricity generating device and will bear the impact of current, in order to increase the stable degree of electricity generating device at the bottom, its framework major part adopts reinforcing bar and concrete to make, and it is very heavy that usual whole device can be built.But the maximum weight that crane barge ship can lift by crane in the world only has 3000 tons.In other words, due to period launch vehicle and lifting tool bears is the gravity of whole electricity generating device, the therefore scale of the electricity generating device restriction of maximum load that instruments such as being subject to crane barge ship can be born.Be subject to the restriction of crane barge ship, the whole weight of tidal current energy generating equipment all must control within 3000 tons.For guaranteeing the lifting of crane barge ship safety and stability and putting down, the weight of tidal current energy generating equipment is preferably far below 3000 tons, and this greatly constrains the large scale development of existing tidal current energy generating equipment.
In addition, tidal current energy generating equipment is fixed on the bottom, as the term suggests electricity generating device will sink, therefore, in prior art, basic nobody is expected in external frame, increase any thing that can produce buoyancy.But, although the utility model provides be fixed on water-bed tidal current energy generating equipment 100, but innovatively buoyancy aid 7 is set in external frame 11, whole tidal current energy generating equipment 100 can first be suspended in water, then can move horizontally external frame 11 in water, whole device just can be dragged to infield by the instruments such as steamer easily.
In the present embodiment, be fixed on water-bed tidal current energy generating equipment 100 and also comprise fixing wirerope 91, external frame 11 is fixed in one end of fixing wirerope 91.When behind arrival infield, fixed by the other end of fixing wirerope 91, the wirerope 91 that is strained and fixed is parallel to the lateral attitude of horizontal plane with fixing external frame 11.Specifically, be provided with multiple fixed tower on the coast with in water, the two ends of fixing wirerope 91 are individually fixed in fixed tower and external frame 11.
Then, the level of external frame 11 is regulated by buoyancy aid 7.After tentatively securing the horizontal position of external frame 11 by fixing wirerope 91, next utilize leveling instrument, detect the level of external frame 11.If external frame 11 is out-of-level, directly Level tune can be carried out by pouring into water to regulate the buoyancy of both sides buoyancy aid 7.
After having adjusted the level of external frame 11, to be sunk under water F along the axial A of outer sleeve 5 one end of every root first inner sleeve 61, the other end stretches out in the water surface.Now, a part for the first inner sleeve 61 connects the bottom of corresponding outer sleeve 5 and water-bed F.Then loosen fixing wirerope 91, in buoyancy aid 7, pour into water to lay down the buoyancy of buoyancy aid 7, external frame 11 is sunk under water F.
In the present embodiment, the outer wall mark of the first inner sleeve 61 has scale (not shown).Therefore, by reading the scale change numerical value outside the first inner sleeve 61, i.e. the level of the known depth of water everywhere rear external frame 11 and judgement is sunk.Because external frame 11 was adjusted to level before sinking, therefore, if the scale numerical value that every root first inner sleeve 61 shows after sinking under water is inconsistent, prove that water-bed corresponding position is irregular.Numerical value changes larger, proves that the bottom is darker herein.If external frame 11 sinks, then inevitable external frame 11 can be positioned at an out-of-level state.
After discovery external frame 11 is out-of-level, the level of adjustment external frame 11.Specifically, in the present embodiment, one end of the first inner sleeve 61 is fixed by winch and external frame 11.When the external frame 11 of side is on the low side, now can drive winch, make the external frame 11 that it lifts this side, when after the special value reading arrival first inner sleeve 61 on the water surface, namely represent external frame 11 level, now stop the continuation of winch 9 to regulate.But the mode of the utility model to the level of adjustment external frame 11 is not limited in any way.In other embodiment, realize the Level tune of external frame 11 by arranging jack.By the outer wall mark scale at the first inner sleeve 61, workmen can intuitively and the whole external frame 11 that forms a prompt judgement comprises platform 11 whether level, thus instruct and further construct.But the utility model is not limited in any way this.When there is no scale outside the first inner sleeve 61, still judge the level of external frame 11 by the degree of depth of actual measurement first inner sleeve 61 submerged.
After having adjusted the level of external frame 11, start to carry out piling work.Because water-bed F is uneven, the first inner sleeve 61 is after submerged, and the bottom of the first inner sleeve 61 all can not contact with water-bed F.First beat to stretch in the first inner sleeve 61 with stake and carry out hammering to water-bed F, after beating out hole, by the first inner sleeve 61 toward pressing down, under making the bottom of the first inner sleeve 61 be embedded into water-bed F a little.Now, except open top, in the first inner sleeve 61, define a substantially airtight space, so complete before spudding in and prepare.
Then stretched into by driling machine in the first inner sleeve 61, the horizon d vertically towards water-bed F is holed, and gets into the degree of depth meeting construction requirement always, forms stake holes 52.In practical application, the degree of depth of stake holes 52, at about 6m, so just can make pile foundation be embedded into horizon d, makes the stake of formation more firm.Take out the first inner sleeve 61 subsequently, inserted by the second inner sleeve 62 in outer sleeve 5, the bottom of the second inner sleeve 62 outer sleeve for connecting 5 and the upper end, ground of water-bed boring, form airtight space again.Then in outer sleeve 5, put into reinforcement cage 54 or steel tube profile, concrete perfusion in outer sleeve 5, form deposited reinforced concrete pile.
